[0061] Example

[0062] The adjustment device used includes: a wireless receiving antenna 1, a motor cover 2, a battery 3, a built-in control receiver 4, a reducer motor 5, a fixing seat 6, a rotating sleeve 7, a compression spring 8, a torsion bar 9, a wireless controller 10, and the wireless receiving antenna 1 and the battery 3 are independently installed on the second frame 12.

A compression spring 8 is provided between the torsion bar 9 and the rotating shaft sleeve 7.

[0064] The second technical solution adopted by the present invention is: an automatic adjustment method for a prefabricated road panel elevation automatic adjustment device based on screw transmission, comprising the following steps:

[0065] Step 1: Set the absolute elevation reference point, set up an automatic tracking total station within 500 meters of the prefabricated road panel to be leveled, and set up the total station monitoring prism at the position of the adjustment bolts 115 at the four corner points of the prefabricated road panel to be leveled;

[0066] Step 2: Insert the bottom ends of the torsion bars 9 of the four automated adjustment devices with the above-mentioned structure into the adjustment bolts 115 of the prefabricated road panel, and fix the automated adjustment device to the prefabricated road panel with the fixing base 6. After installation, the compression spring 8 is in a compressed state between the top surface of the prefabricated road panel and the fixing base 6.

[0067] Step 3: The operator sets up an automatic tracking total station through the PAD, and measures the real-time elevation of each corner point of the adjustment bolt 115 of the leveling panel through the automatic tracking total station, and sends the real-time elevation information to the control terminal using a wireless signal;

[0068] Step 4: Input the design elevation information of the position of the prefabricated road panel adjustment bolt 115 into the control terminal;

[0069] Step 5: The control terminal calculates the adjustment stroke of each adjustment bolt 115 based on the design elevation information and the real-time elevation information, and sends the calculated value to the automatic adjustment device using a wireless signal.

[0070] Step 6: The automatic adjustment device receives the signal through the wireless receiving antenna 1 and transmits the signal to the wireless controller 10;

[0071] Step 7: The built-in control receiver 4 controls the reducer motor 5 to work. The output shaft of the reducer motor 5 rotates and drives the torsion bar 9 to rotate in the hole of the adjustment bolt 115. The torsion bar 9 drives the adjustment bolt 115 to rotate, so that the corner points of each adjustment bolt 115 move up and down.

[0072] Step 8: The automatic tracking total station measures the elevation of the corner points of the adjustment bolt 115 in real time and compares it with the design elevation information. When the difference between the real-time elevation and the design elevation meets the error requirement, the wireless controller 10 is used to control the reducer motor 5 to stop working, completing the adjustment of the elevation of each corner point of the road panel.

[0073] In this method, the rotation of the torsion bar 9 drives the adjustment bolt 115 at the corner point to rotate, thereby adjusting the elevation of the corner point. By setting up a total station to measure the elevation of each corner point of the road panel in real time, and obtaining the difference between the design elevation and the real-time elevation in the control terminal, the reducer motor 5 is controlled according to the difference to drive the torsion bar 9 to rotate, completing the adjustment of the elevation of the monitored corner point. During this adjustment process, only the design elevation needs to be input manually, and the adjustment process and the adjusted elevation can be measured in real time. The adjustment efficiency is high, the adjusted elevation results are uniform, the error is small, it is not affected by human factors, and the operation is simple.
