[0033] The working principle of the utility model is as follows: when installing the pedal, it is necessary to first fix the pedal frame 4, and manually twist the threaded rod 66 to make it rotate. Under the action of the threaded connection, the threaded rod 66 will push the movable plate 65 to move backward. Under the sliding action of the fixed block 61 and the slide bar 63, the movable plate 65 will not rotate with the threaded rod 66, and can only move forward and backward. After the movable plate 65 and the inner wall of the fixed block 61 clamp the tower crane main frame 1, the pedal frame 4 can be preliminarily fixed, and then the pedal frame 4 and the pedal frame 25 are connected using the installation accessories 2, the fixed frame 21 is placed on the upper end of the tower crane main frame 1, and then the L-shaped plate 23 is connected to the support block 22 with bolts. The bolts pass through the pedal to fix it. The anti-skid pad 24 prevents the installation accessories 2 from sliding, posing a safety hazard. After using three anti-skid pads 234 in succession, it is completely When fixing the pedal frame 1 4 and the pedal frame 2 5, the installation direction of the installation accessory 2 3 is opposite. The fixing frame 2 31 is placed on the upper end of the tower crane main frame 1, and the L-shaped plate 2 33 and the support block 2 32 are connected with bolts. The bolts can also fix the pedal. The anti-skid pad 2 34 plays an anti-skid role. When objects falling from a high altitude hit the pedal, they will hit the buffer pad 76 and the load-bearing plate 75. The load-bearing plate 75 pushes the buffer block 74 to move downward. When the buffer block 74 moves, it will squeeze the supporting spring 73 to make it shrink, and also make the rotating rod 78 rotate. When the rotating rod 78 rotates, it will push the slide groove 72 to move in the opposite direction. When the slide groove 72 moves, it will squeeze the elastic spring 70 to make it shrink. Under the back and forth expansion and contraction of the elastic spring 70 and the support spring 73, the object can be buffered without causing damage to the pedal. The through holes opened in the load-bearing plate 75 and the buffer pad 76 prevent rainwater from accumulating on the upper end of the buffer pad 76.
