Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery assembly, in particular to a counterweight block installation assisting mechanism. Background Art

[0002] When assembling parts of engineering machinery, aerial work vehicles are indispensable. Taking the AGV aerial work vehicle as an example, when supporting the parts to a high place, in order to improve the stability of the AGV aerial work vehicle, it is necessary to counterweight the AGV aerial work vehicle to prevent the AGV aerial work vehicle from tipping over and ensure that the assembly of engineering machinery is safer. In order to stably install the counterweight block, power-assisting equipment is needed.

[0003] In the related technology, it was found through search that a new type of counterweight moving assist arm (announcement number CN211034979U) solves the problem of inconvenient and quick clamping of the counterweight through the coordination between the first cylinder, the second cylinder, the servo motor and the rotating column, and achieves the effect of accurately adjusting the clamping position and the clamping angle according to the position of the counterweight, thereby improving work efficiency.

[0004] The above scheme uses two oil cylinders to adjust the height of the clamping block, and the slide cylinder controls the two clamping blocks to clamp the counterweight block. When transporting the counterweight block, it can only clamp the counterweight block by clamping. When adjusting the height of the counterweight block, the clamping block and the counterweight block may be in a tilted state. At this time, there is a risk of the counterweight block slipping, and there is a safety risk in transporting the counterweight block. In addition, AGV aerial work vehicles usually have reserved receiving grooves on the side to place the counterweight blocks. The size of the receiving grooves is generally corresponding to the counterweight blocks. After the counterweight blocks and the clamping blocks are accommodated in the receiving grooves at the same time, the space is small. It is necessary to accurately control the clamping blocks to be inserted into the receiving grooves and stack the counterweight blocks. There are requirements for operating accuracy, which affects the stacking efficiency of the counterweight blocks. Utility Model Content

[0005] The purpose of the utility model is to provide a counterweight installation assisting mechanism to solve the problems raised in the above-mentioned background technology.

[0013] Furthermore, a sleeve is installed at the lower end of the bent arm, a right-angle arm is rotatably connected inside the sleeve, the right-angle arm is fixedly connected to the load-bearing frame, and a brake cylinder inserted into the sleeve is installed on the surface of the sleeve. The brake cylinder can limit the free rotation of the right-angle arm, thereby preventing the load-bearing frame from rotating freely and avoiding the load-bearing frame from injuring the staff.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The double-axis cylinder drives the loading and unloading seat to move to the top of the counterweight block through the plug arm, and cooperates with the plug arm to fix the counterweight block to prevent it from falling from the plug arm. When the lifting cylinder controls the lifting of the counterweight block, the counterweight block is placed horizontally on the plug arm to ensure that the counterweight block will not slip during transportation, which is safer to use.

[0016] (2) The arm supports the counterweight from below, and the arm does not occupy the space on the side of the counterweight. When the counterweight is placed into the receiving slot of the AGV aerial work vehicle, the counterweight can be placed on the AGV aerial work vehicle more quickly.
