As a new floor construction equipment, laser leveling machine has attracted wide attention from the industry due to its excellent construction efficiency and construction accuracy as soon as it entered the market, and has been increasingly used in large-scale concrete floor construction in warehouses, basements, parking lots, industrial plants, etc. Like other construction machinery, laser leveling machine is also a whole composed of many parts, and the construction environment is relatively complex, so it is easier to wear than general mechanical parts during long-term work. In order to extend the effective service life of the laser leveling machine, the following is a brief introduction to the main components of its parts and the tips for use and maintenance. —-Core components and functions of laser leveling machine—- ➤Transmission system: mainly composed of transmission, universal joint, transmission shaft and drive axle; ➤Travel system: composed of frame/axle/suspension/wheels, etc. The function is to support the quality of the whole vehicle and ensure the driving of the laser leveler; ➤ Steering system: It is composed of steering wheel, steering gear, steering knuckle, steering knuckle arm, tie rod, straight tie rod, etc., and its function is steering; ➤ Hydraulic brake: The hydraulic brake device is composed of brake pedal, master brake cylinder, slave cylinder, drum brake and oil pipe and other parts; ➤ Transmission: It is composed of transmission case, transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing, operating mechanism and other parts, which are used for laser leveler speed change and output torque change; ➤ Leaf spring and shock absorber: The function of leaf spring is to maintain elastic connection between frame and body and wheels or axles. The function of shock absorber is to ease vibration when laser leveler is subjected to vibration shock; ➤ Starter: Its function is to convert electrical energy into mechanical energy, drive crankshaft rotation, and start engine. If the continuous starting time is too long, the battery will be discharged in large quantities and the starter coil will overheat and smoke, which will easily damage the laser leveling machine parts; ➤Battery: The function of the battery is to supply electricity to the starter, and to supply power to the engine ignition system and other electrical equipment when the engine is started or running at low speed. When the engine is running at high speed, the generator generates sufficient electricity, and the battery can store excess electricity; ➤Motor: The motor is the power device of the laser leveling machine. Its main function is to generate driving torque as a power source for electrical appliances or various machines. Its main function is to convert mechanical energy into electrical energy. At present, it is more commonly used to use heat energy, water energy, etc. to drive the generator rotor to generate electricity. —-Use and maintenance of core parts of laser leveling machine—- ➤Regularly replace lubricating oil to ensure that all parts of the machine are well lubricated and reduce the wear of parts; ➤Keep the whole machine and parts clean regularly, and tighten loose parts in time to prevent loose parts from aggravating the wear of parts or causing the loss of parts; ➤Pay attention to the workload of each part during the running-in period. The workload during the running-in period should generally not exceed 80% of the rated workload, and deploy appropriate workload to prevent overheating caused by long-term continuous operation of the laser leveling machine; ➤Start the leveling machine engine once every half a month to charge the battery and run all hydraulic actuators, such as rotating hydraulic motors, telescopic cylinders, etc. Do not remove the battery from the machine to prevent the failure of the controller's internal software program being lost due to long-term parking of the equipment; ➤Start the leveling machine regularly and turn on all hydraulic functions on the machine to allow the hydraulic drive components to work regularly to prevent the relevant seals from being damaged due to long-term parking, and metal components such as cylinder rods from rusting. Try to retract all cylinder rods into the hydraulic cylinder oil chamber as much as possible to better protect the surface of the cylinder rod. Reasonable use and regular maintenance of various components are effective ways to extend the service life of the laser leveling machine and improve the economic benefits of the operation. It is recommended that before using the leveling machine, you should be fully familiar with the composition and functions of each component of the machine, master the correct operation method, and strengthen daily maintenance.

Concrete pressure strength detection method 1. Rebounder or Schmitt Hammer (ASTM C805) Method: The hammer is activated by a spring release mechanism, which presses the plunger and presses it into the concrete surface. The rebound distance from the hammer to the concrete surface is in the range of 10 to 100. The measurement results are then associated with the strength of the concrete. Pros: Relatively easy to use and can be done directly in the field. Cons: To ensure accurate measurementresults, pre-calibrated concrete samples are required. Different states of the surface and the presence of rebar under large aggregates or test sites can affect the test results. 2. Penetration test (ASTM C803) Methods: When carrying out a penetration test, a pin or probe is drilled into the concrete surface with a special device. The strength and depth of drilling required to drill into a concrete surface are related to the strength of the poured concrete. Pros: Relatively easy to use and can be done directly in the field. Cons : The data are greatly influenced by conditions such as surface state, template type, and aggregate used. Accurate strength measurements require multiple sampling of concrete samples for early calibration. 3. Ultrasonic pulsation detection (ASTM C597) Method: This method is used to judge the velocity of the vibration energy pulsation in the ground floor. The ease with which this energy penetrates the floor plate reflects the results of the concrete's ability to elastic, resist deformation or stress, and density. The data is then associated with the strength of the concrete slab. Pros: This is a non-destructive testing method and can also be used to detect defects such as cracking or honeycomb holes inside concrete. Cons: The method is seriously affected by the enhancement method, the moisture in the aggregate and the concrete material. Multiple samples and calibrations are also required to obtain accurate test results. 4. Pull-up test (ASTM C900) Method: The main principle of this method is to pull the metal rod, which is poured inside or installed afterwards, out of the concrete. The cone after pulling out and the amount of force required to pull out from the concrete are related to the strength of the pressure. Pros: Easy to use, can be done in both old and new building structures. Cons: This detection can cause the concrete to break or damage. To obtain accurate test results, a large number of test samples need to be selected at different locations on the floor plate. 5. Drill core method (ASTM C42) Method: The drill core method is used to extract solidified concrete sample blocks from the floor plate. These samples are then compressed in the machine to monitor the strength of their concrete. Pros: These samples are more accurate than field solidification samples because the concrete of strength is tested by actual heat and solidified on site. Cons: This is a destructive detection method that requires the destruction of the structural integrity of the concrete slab. The position of the core needs to be patched after the fact. The strength data must be obtained by the lab. 6. Poured concrete cylinder detection method (ASTM C873) Method: The cylindrical mold is placed in the position of the pouring area. Fresh concrete is discharged directly into these molds, which are retained in the floor board. After the floor plate solidifies, remove the specimens and pressurize them to detect their strength. Pros: This method is considered to be more accurate than on-site cured specimens because the concrete undergoes the same solidification process and conditions as the site floor plate; Cons: This is a destructive detection method that requires the destruction of the structural integrity of the concrete slab. The hole position left after the specimen is removed needs to be repaired afterwards. The strength data must be obtained by the lab. 7. Wireless Maturity Sensor (ASTM C1074) Methods: The principle of this method is based on the direct relation of concrete strength and its hydration temperature history. Before starting pouring, the wireless sensor is placed in a concrete template and secured on the rebar. The sensor receives temperature data and uploads it to any smart device APP with a wireless connection. According to the maturity calculation formula of the setting number in the APP, the collected information is used to calculate the pressure strength of the concrete element at the current position. Pros: Anti-pressure strength data is fed back in real time and updated every 15 minutes. At the same time, because the sensor is embedded inside the template, the data accuracy and reliability are also ideal, i.e. the curing data collected is consistent with the in situ concrete element. This also means that you don't have to spend time waiting for a third-party lab to provide the test results. Cons: Each batch of mating concrete needs to create a maturity curve using a test method of a collapse dwelling barrel and complete a one-time calibration.
