Detailed Description
In the figure, the utility model is provided with a frame 20, two main bearing wheels 15 are arranged at the lower part of the frame 20, and an auxiliary wheel 14 is also arranged at the lower part of the frame 20. The driving wheel shaft 18 is fixed on the frame 20 through the bearing 17, the rubber driving wheel 19 is welded with the driving wheel shaft 18, two lifting arm rotation driving synchronous pulleys 16 are fixed at two ends of the driving wheel shaft 18 through keys, the lifting arm rotation shaft 7 passes through the bearing 8 and is fixed on the upper part of the frame 20, the lifting arm rotation shaft 7 and the driving wheel shaft 18 are arranged in parallel, two lifting arm rotation driven synchronous pulleys 5 and two supporting claw limiting driving synchronous pulleys 6 are connected to two ends of the lifting arm rotation shaft 7, the lifting arm rotation driven synchronous pulleys 5 are connected with the lifting arm rotation driving synchronous pulleys 16 through the lifting arm rotation synchronous belts 9, two lifting arms 3 are welded on two sides of the lifting arm rotation shaft 7, the supporting claw 4 is hinged on the lifting arm 3 through a pin shaft, the supporting claw limiting driven synchronous pulleys 1 are installed at the upper ends of the lifting arm 3, the supporting claw limiting driven synchronous pulleys 1 are connected with the supporting claw limiting driving synchronous pulleys 6 through the supporting claw limiting synchronous belts 2, the lifting arm locking block 10 is hinged on the frame 20, one end of the lifting arm locking block reset tension spring 11 is fixed on the lifting arm locking block 10, the other end of the lifting arm locking block is connected with the lifting arm locking block 13 through the other end of the pulling rope 13, and the other end of the pulling arm locking block is separated from the lifting arm locking block 13.
The pressing frame 20 enables the rubber driving wheel 19 to contact the ground, and the rubber driving wheel 19 is driven to rotate through the traction vehicle, so that the driving wheel shaft 18 welded with the rubber driving wheel 19 drives the lifting arm rotation driving synchronous pulley 16 to rotate, and then the lifting arm rotation driving synchronous pulley 16 drives the lifting arm rotation driven synchronous pulley 5 to rotate through the lifting arm rotation synchronous belt 9, and drives the lifting arm 3 welded with the lifting arm rotation shaft 7 to rotate, so that the lifting function of the supporting claw 4 is realized.
The lifting arm locking block 10 is hinged on the frame 20 through a pin shaft, can swing up and down around the pin shaft, one end of a lifting arm locking block reset tension spring 11 is fixed on the lifting arm locking block 10, and the other end of the lifting arm locking block is fixed on the frame 20, so that the lifting arm locking block 10 is always in a state of locking the lifting arm rotation driven synchronous pulley 5 when no external force exists. The lifting arm locking block separation traction rope 13 bypasses one end of the guide wheel 12 and is fixed to the lifting arm locking block 10, the other end of the lifting arm locking block separation traction rope is fixed to the traction rope control handle 21, the traction rope control handle 21 is pressed, the lifting arm locking block separation traction rope 13 is pulled to further pull the lifting arm locking block 10 to be separated from the lifting arm rotation driven synchronous pulley 5, and the locking state of the lifting arm rotation driven synchronous pulley 5 is released.
