The guide seat 2 and the roller seat support 4 are respectively and fixedly installed on the front vertical plate 7, the spring rod 1 can move in the guide seat 2, the bottom plane of the spring rod 1 is in contact with the roller 3, the roller 3 is installed on the roller seat support 4 and can rotate around the roller seat support 4 through the connection of a pin shaft and the like, the roller seat 5 is hinged on the roller seat support 4, the roller seat 5 can rotate around the shaft of the roller seat support 4, the roller seat support 4 and the roller seat 5 are installed in an assembling mode, the connection performance is stable, and the assembly and disassembly are convenient. The connecting rod 6 is connected with the roller seat 5 and the protection plate 8, the connecting part of the connecting rod 6, the roller seat 5 and the protection plate 8 can rotate, and the front vertical plate 7 is provided with a slotted hole 11 for a shaft of the roller seat 5 to pass through in the movement. The gas spring 10 is connected with the front vertical plate 7 and the connecting rod 6, the connection part can rotate, and the length of the gas spring 10 can be compressed.
Thus, the spring rod 1, the guide seat 2, the roller 3, the roller seat support 4 and the roller seat 5 are positioned outside the front vertical plate 7, and the shaft portion of the roller seat 5, the connecting rod 6 and the gas spring 10 are positioned inside the front vertical plate 7.

It can be seen that, when the protection plate 8 is in a closed state, the spring rod 1 is pressed down under the action of the oil cylinder support, the bottom of the spring rod 1 is in contact with the roller 3, the roller 3 rotates downwards around the roller seat support 4, correspondingly, the roller seat 5 rotates upwards around the roller seat support 4, the shaft of the roller seat 5 moves along the direction of the slotted hole 11, the connecting rod 6 is driven, and the protection plate 8 is further driven to rotate to a horizontal state around the hinged point of the protection plate 8 and the vertical plate.
When the aerial work platform travels to a hollow ground, the oil cylinder support rises and leaves the elastic device, the force acting on the spring rod 1 is removed, at the moment, the protection plate 8 rotates downwards to be vertical under the action of the self gravity of the protection plate 8 and the connecting rod 6, the shaft of the roller seat 5 moves to the lowest position of the shaft on the vertical plate along the reverse direction of the slotted hole 11, correspondingly, the roller 3 rotates upwards around the roller seat support 4, the spring rod 1 moves upwards in the guide seat 2, at the moment, the lower side included angle between the connecting line of the hinge point A and the hinge point B and the connecting line of the hinge point C and the hinge point B is larger than or equal to 180 degrees, and when the lower side included angle is equal to 180 degrees, the two connecting lines are positioned on the same straight line. Therefore, the opened protection plate 8 is supported by the dead point of the mechanism, and meanwhile, under the elastic action of the gas spring 10 and the limiting action of the slotted hole 11, the protection plate 8 is maintained in an opened stable state, the protection plate is prevented from being accidentally closed due to external load, and only when the fork frame descends, the oil cylinder support presses the spring rod 1 down, and the protection plate 8 can be driven to be closed after the elastic force of the gas spring 10 and the self gravity of each component are overcome.
The aerial work platform pothole protection device of the embodiment can utilize the mechanism dead point to support the opened protection plate 8 when the protection plate 8 is in the opening state in the working state, so that the protection plate 8 cannot be closed under the action of external load. The retraction of the shielding plate 8 can be driven if and only if the spring rod 1 is subjected to a sufficiently strong downward pressure to overcome the spring force of the gas spring 10 and the self-weight of each member. Therefore, the hollow protection device of the aerial work platform has good stability.

Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
