[0041] The communication module 16 is fixed to the trolley steel structure 2 through the threaded structure 19 on the body of the communication module 16, and the communication module 16 can rotate in one degree of freedom through a corresponding mechanical mechanism, and the rotation range of the vertex is circular.

[0042] The battery 17 is divided into positive and negative electrodes, and the whole battery 17 is placed in the trolley steel structure 2 through the trolley steel structure 2 below, to supply power to other components.

[0043] The magnetic coupling 10 is divided into three parts, namely the driving shaft 11, the linkage 12 and the driven shaft 13, wherein the driving shaft 11 is directly connected with the main shaft of the servo motor, the linkage 12 is divided into two parts inside, and strong magnets are uniformly distributed inside, so that the driving shaft 11 and the driven shaft 13 realize power contactless transmission, the driven shaft 13 is connected with the lifting rod 14, so as to realize lifting work, through power contactless transmission, when the torque of the lifting rod 14 is too large and overloaded, the magnetic field will slide to limit the maximum transmission torque, so as to avoid overload and potential damage to the driven equipment, this overload protection can prolong the service life of the equipment and avoid excessive current of the servo motor.

[0044] The circuit adopted by the utility model is that the infrared distance sensor is powered through VCC and GND bus, and the input voltage is stabilized to 5V by using 7805 stabilizer. The filter capacitors C1 and C2 ensure the stability of the power supply. The core is STC89C51 single-chip microcomputer, which utilizes 12MHz crystal oscillator and 30pF capacitor to provide stable clock signal.

[0045] When using this utility model, it first needs to be assembled. Specifically, the battery 17 is installed from the lower part of the trolley steel structure 2; the communication module 16 is installed through the threaded structure 19; the infrared ranging sensor 5 is attracted by the magnetic suction plate 18 and its position is adjusted. The specific position requirement is: the construction worker's hand movements are used to simulate the traction of the guide plate 21. When it reaches about 500mm away from the line laying trolley, the lifting rod 14 is activated.

[0046] Then, it is necessary to check the working status of this utility model, including: checking whether there are any rust marks on the entire wire-laying trolley, checking whether the battery 17 is powered properly, checking whether the infrared ranging sensor 5 is working properly, checking whether the bolts of the trolley movable hanging plate 3 are fully tightened, checking whether the pin can be fully inserted and locked, and checking whether the communication module 16 can receive signals and work properly.

[0048] In operation, specifically, when the guide rope, traction board, and wire are successively pulled to the vicinity of the wire-laying pulley, the operator reduces the traction speed. The infrared ranging sensor 5 detects the traction board and continuously sends a distance signal. When the traction board 21 reaches a certain distance from the wire-laying pulley, the communication module sends a working signal, and at the same time, the battery 17 increases its output power, the motor starts working, the lifting rod 14 is raised, lifting the traction board and the wire to prevent the traction board 21 from getting stuck on the wire-laying pulley. The small pulley on the upper part of the lifting rod 14 can slide freely, reducing friction with the wire. When the infrared ranging sensor 5 no longer detects the traction board, it stops sending a distance signal, the motor stops working, and the communication module 16 sends a work completion signal, indicating that the work is completed.
