[0006] When the baffle is removed from the front surface of the elevator, the user pulls the pull rod to the right, which drives the counterweight block to move to the right at the same time. Then, when the counterweight block moves, the counterweight block is limited by the limit block. Then, the user moves an appropriate amount of counterweight block to the right side of the bottom end of the elevator.

[0007] Preferably, the shape of the limit block matches the limit groove provided inside the elevator.

[0008] Preferably, a specific groove is formed inside the baffle.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is arranged such that when the counterweight device of the aerial work lift is put into use, the position of the counterweight block is adjusted by using the sliding mechanism, and the counterweight block is fixed by the fixing mechanism after being moved. Through the coordinated use of the above structures, the problem that when the top platform of the lift is extended to both sides, the position of the counterweight block cannot be adjusted, which easily leads to a decrease in the stability of the lift is solved.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-5The utility model provides a technical solution: a counterweight device for an aerial work lift, comprising a lift 1 and rollers 2, wherein rollers 2 are arranged at the four corners of the bottom end of the lift 1, and the counterweight device for the aerial work lift also comprises: a sliding mechanism 3 is arranged inside the lift 1, and a fixing mechanism 4 is arranged at the bottom end of the sliding mechanism 3, wherein the sliding mechanism 3 is used to distribute the counterweight to the lift 1, and then fix it through the fixing mechanism 4, and a limiting groove is provided at the bottom end of the interior of the lift 1.

[0018] More specifically, the sliding mechanism 3 includes: a counterweight block 301, a pull rod 302, a limit block 303, a slot block 304 and a baffle 305;

[0019] The counterweight block 301 is movably arranged at the inner bottom end of the elevator 1, and the counterweight block 301 is used to counterweight the elevator 1. The pull rod 302 is fixedly arranged on the front surface and the back of the counterweight block 301, and the pull rod 302 is convenient for pulling the counterweight block 301. The limit block 303 is fixedly arranged on the front surface and the back of the counterweight block 301, and the limit block 303 is arranged at the bottom end of the pull rod 302. The groove block 304 is fixedly arranged at the bottom end of the counterweight block 301, and the groove block 304 can be clamped by the blocking rod 403. The baffle 305 is detachably arranged on the front surface of the elevator 1, wherein the limit block 301 is pulled to the right by the pull rod 302 so that the counterweight block 301 can be limited by the limit block 303. The shape of the limit block 303 matches the limit groove opened inside the elevator 1, and a specific groove is opened inside the baffle 305.

[0020] More specifically, the fixing mechanism 4 includes: a support block 401, a rotating rod 402, a stop rod 403, a slot rod 404 and a bolt 405;

[0021] The support block 401 is fixedly set on the left side of the bottom end of the elevator 1, and the support block 401 is used to support the rotating rod 402. The rotating rod 402 is rotatably set on the right side of the support block 401, and the blocking rod 403 is equidistantly fixed on the outer wall of the rotating rod 402. The groove rod 404 is sleeved on the outer wall of the rotating rod 402. The groove rod 404 is used to limit the support of the rotating rod 402, and the top of the groove rod 404 is connected to the bottom end of the elevator 1. The bolt 405 is threadedly set inside the groove rod 404, and the screw 405 can fix the rotating rod 402, wherein when the rotating rod 402 rotates, it can drive the blocking rod 403 to clamp into the inside of the groove block 304 to fix it.

[0022] Working principle: When the counterweight device of the aerial work lift is used, when the lift 1 is raised, the bottom end of the lift 1 can be counterweighted by the counterweight block 301. When the top platform of the lift 1 needs to extend to the left, the user needs to move the weight block 301 at the bottom end. The user first removes the baffle 305 from the front surface of the lift 1, and then pulls the pull rod 302 to the right, which drives the counterweight block 301 to move to the right at the same time. Then, when the counterweight block 301 moves, the limit block 303 limits the counterweight block 301. After the user moves an appropriate amount of counterweight 301 to the right side of the bottom end of the lift 1, the user rotates the rotating rod 402 90 degrees to rotate the blocking rod 403 into the specific slot of the slot block 304, and then fixes the slot block 304 through the blocking rod 403 to indirectly fix the moved counterweight 301, and then the user rotates the bolt 405 from the bottom end of the slot rod 404 to its inside to squeeze and fix the rotating rod 402, and then the counterweight moved to the right side of the bottom end of the lift 1 can effectively ensure the stability of the lift 1 after the left side is extended.
