[0029] The following is combined with Figure 1-5 The utility model is described in further detail.

[0030] The utility model embodiment discloses a fender of a lifting platform.

[0031] Reference Figure 1 , 2 , including a base bracket 1 and a plurality of bolts, two legs 2 are fixedly connected on both sides of the base bracket 1, and a guard plate 3 is detachably connected to one side of each leg 2 through a part of bolts, each guard plate 3 is located between the leg 2 and the track 7, and the guard plate 3 is connected to the outer cover 21 of the leg 2 through bolts. After the bolts are removed, the guard plate 3 and the leg 2 are in a disconnected state; the bottom of the base bracket 1 is fixedly connected to the track 7, and the lowest point of the guard plate 3 is higher than the lowest point of the track 7. When the base bracket 1 is operating in muddy ground, the track 7 is easy to bring up mud, and the guard plate 3 prevents mud and dirt from contaminating the leg 2, thereby acting as a mudguard for the leg 2.

[0032] Reference Figure 2 , 3, each leg 2 includes an outer cover 21 and a welding plate 22, and an oil cylinder is fixed inside each leg 2. The inner wall of the bottom of each outer cover 21 is detachably connected to the outer surface of the top of the corresponding welding plate 22 through a part of the bolts, and the outer cover 21 is bolted to the welding plate 22. When the leg 2 needs to be disassembled, the bolts are first removed to separate the outer cover 21 and the welding plate 22, and then the oil cylinder and hydraulic cylinder 4 inside are cleaned and repaired. A hydraulic cylinder 4 is clamped inside each welding plate 22, and the hydraulic cylinder 4 drives the ground contact member 5 to move down and contact the ground. When the crawler 7 moving equipment is in a walking state, the ground contact member 5 is driven by the hydraulic cylinder 4 to be suspended in the air. After the crawler 7 stops operating, the four hydraulic cylinders 4 drive the leg 2 to move in a direction close to the ground until the ground contact member 5 contacts the ground. When the crawler 7 is replaced or maintained and repaired, the four hydraulic cylinders 4 drive the leg 2 to move in a direction close to the ground until the crawler 7 is suspended in the air.

[0033] Reference Figure 1 , 3 The end of the output shaft of each hydraulic cylinder 4 is fixedly connected with a ground contact member 5, which supports the support leg 2 to contact the ground. When working in muddy ground, the ground contact member 5 is located at the bottom of the support leg 2, which can prevent the oil cylinder and hydraulic cylinder 4 inside the welding plate 22 from being contaminated.

[0034] Reference Figure 1 , 2 , 4, 5, one side of each guard plate 3 is overlapped with the outer surface of the corresponding ground contact member 5, the outer surface of the guard plate 3 is provided with two through holes, the inside of each through hole is plugged into the outer surface of the corresponding bolt, the guard plate 3 includes a rectangular area and an inverted trapezoidal area, the inverted trapezoidal area of ​​the guard plate 3 is beneficial to reduce the material loss of the guard plate 3, and is simple to clean, guides the flow direction of the dirt, reduces the flow range of the dirt when it flows downward, and reduces the impact on the operating efficiency of the crawler 7.

[0035] Reference Figure 3 The four ground contact components 5 each include a grounding plate 51, a cover 52 and a support ball 53. The end of the output shaft of each hydraulic cylinder 4 is fixedly connected to the top of the corresponding support ball 53. The bottom of each support ball 53 is adapted to the interior of the corresponding grounding plate 51. The bottom of the support ball 53 is a spherical surface. After contacting the interior of the grounding surface, the area for transmitting pressure is the largest, and the pressure can be transmitted better. The bottom of each support ball 53 is overlapped with the interior of the corresponding grounding plate 51. The bottom of the grounding plate 51 moves in the direction close to the ground driven by the hydraulic cylinder 4 until it is in contact with the ground.

[0036] Reference Figure 3The interior of each cover 52 is sleeved on the outer surface of the corresponding support ball 53, and the outer surface of each cover 52 is detachably connected to the top of the corresponding floor 51 through a portion of corresponding bolts. The cover 52 is bolted to the grounding plate 51, and the support ball 53 is locked to the inside of the grounding plate 51 by tightening the bolts. When the grounding plate 51 is worn, the bolts need only be removed to replace the grounding plate 51.
