How to evaluate the performance & stability of laser receivers?

  The development of concrete laser leveling machine is the need of the times! The concrete laser leveling machine adopts the principle of laser leveling, which is more scientific and accurate than the traditional manual measurement method, and greatly reduces the error value caused by manual measurement. For some environments that require ultra-flat ground Said that this way of working is more acceptable and more in line with the needs of users. (1) The leveling principle of the laser leveling machine is realized under the automatic control of the computer by using precision laser technology, closed-loop control technology and highly precise hydraulic system. This is the most prominent difference between it and other floor construction processes. specialty. (2) The leveling principle of the precision laser leveling machine is to rely on the leveling head driven by hydraulic power, cooperate with the laser system and the computer control system to complete the leveling work while automatically leveling. The leveling head is equipped with an integrated scraper, vibrator and leveling plate, which integrates all leveling, leveling, vibration and compaction work, and completes it at one time. The computer control system automatically adjusts the elevation 10 times per second in real time, and the vibration frequency of the vibrator with a balanced design reaches 3000 times per minute. (3) The laser transmitter used to control the ground level is arranged independently, so that the level of the ground is not controlled by the template, and no cumulative error will occur.     The original traditional labor-intensive operation methods no longer meet the needs of development. The integration of machinery and equipment and intelligence must have become the mainstream of the times. The current construction industry has already adopted laser leveling machines to replace the traditional ground paving mode. Rapid paving of large areas can ensure the quality of construction. The ground paved by this equipment is more flat and compact, so that the flatness of the ground is guaranteed. The laser leveling machine has a high leveling ground, which significantly improves the flatness of the ground. The ground constructed by the laser leveling machine and the traditional method are tested at 22 points (one point every 5mx4m), and the average flatness is 1.3mm and 4.1mm respectively. The leveling quality of the laser leveling machine can be improved by more than 3 times compared with the traditional method. Reduce the amount of side formwork dismantling: Based on the statistics of 20,000 square meters of concrete pavement, the traditional method needs to dismantle 5800m of side formwork, but with advanced equipment such as laser leveling machines, the dismantling of 2500m can reduce the support modulus by more than 74%. Fast construction speed: use laser leveling machine and other equipment to construct large slabs, which improves the work efficiency by 3 times compared with the traditional beam vibrator method, saves 30%, and can complete 3000 square meters per day on average, especially suitable for large-scale concrete surface construction. High degree of automation and low labor intensity: the use of laser leveling machine equipment can change the heavy manual labor into mechanical paving, vibrating, leveling, pulp extraction, and surface plastering, reducing the number of operators by 30% and reducing labor intensity. The application of equipment such as laser leveling machines can realize large-scale construction, effectively reduce a large number of construction joints, and the concrete slump can also be significantly reduced. The concrete strength is guaranteed, so that the ground integrity is good and cracks are not easy to appear. High economic benefit, the use of laser leveling machine can save 2-3 yuan per square meter compared with the traditional process, less seams, and lower maintenance costs in the later period, so that the economic benefit can be significantly improved.    

The use and promotion of concrete paving and leveling machines has ended the traditional construction of using mortar to punch piers, finding elevations, laying out side formwork, dump trucks to transport concrete, manual preliminary leveling, scraping with flat plates, and vibrating concrete with vibrators. Then a special double-row steel pipe is used to vibrate and tamp and level it back and forth. So how much do you know about this device? Next, I will give you a detailed introduction to the basic configuration of the concrete paving and leveling machine equipment. Let's learn more about it together. The basic configuration of concrete paving and leveling machine equipment is introduced in detail as follows: 1. The laser leveling machine uses precision laser technology, closed-loop control technology and a highly precise integrated hydraulic system, and is realized under the automatic control of a microcomputer. This is what distinguishes it from other floor construction techniques. 2. The concrete paving and leveling machine relies on a hydraulically driven leveling mechanism and cooperates with the laser system and computer control system to complete the leveling work while automatically leveling. 3. The laser transmitter used by the concrete leveling machine to control the ground elevation is independently arranged, and the floor elevation will not produce cumulative errors. Compared with traditional methods, the construction joints on the floor can be greatly reduced, and the subsequent maintenance costs of the ground and the use of formwork are also greatly reduced. 4. The laser transmitter equipped with the concrete paving and leveling machine can automatically control both the plane and the two-way slope. It is also completed by the laser system, microcomputer system, hydraulic system, and mechanical and electronic system. For complex-shaped floors with high requirements such as drainage, a three-dimensional special-shaped ground treatment system can also be selected. 5. Using solid anti-puncture tires, paving and leveling operations can be performed directly on the steel mesh. 6. The concrete paving and leveling machine comes with a high-pressure cleaning system, which greatly facilitates the cleaning of the bonded concrete on the machine, ensures the normal use of the machine, and extends the service life of the machine.
