In actual work, the existing lifting equipment has a large lifting height of the suspension arm, and the hoist is installed with rollers for easy movement. However, installing rollers is not conducive to the daily suspension operation of the hoist and reduces the stability of the equipment.

[0003] In the prior art, a Chinese patent document with publication number CN113200461A is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a kind of lifting equipment for water conservancy and hydropower engineering construction, including a base, a reduction motor is vertically fixedly installed at the center position of the bottom end of the base, a rotating table is arranged at the top of the base, the output end of the reduction motor passes through the base and is vertically fixedly connected to the center position of the bottom end of the rotating table, a suspension mechanism is fixedly installed at the top of the rotating table, a supporting mechanism is fixedly installed on the side wall of the rotating table, and reinforcement mechanisms are vertically fixedly installed at the four corners of the bottom end of the base.

[0004] In order to solve the problem that the rollers installed on the hoist are not conducive to the daily suspension operation of the hoist and reduce the stability of the equipment, the existing technology adopts the method of setting up a supporting mechanism and a reinforcement mechanism to deal with it. However, the hoisting rope of the hoisting equipment is not infinite and is prone to large shaking, which makes it difficult to stabilize the hoisted object due to the shaking, and the shaking is prone to friction and damage.

By setting the limit assembly, the swing range can be limited by passing the lifting rope through the limit rod, thereby preventing the lifting object from shaking significantly due to force during the rotational movement, thereby causing unstable lifting and the risk of wear. By setting the arc-shaped rack, the limit rod can be moved on the arc-shaped rack, so that it can cooperate with the adjustment seat to perform horizontal adjustment according to the inclination angle of the supporting main rod, so that the limit rod remains horizontal to limit the lifting rope, thereby improving the stability of the limit.
