Buffer spring fixing structure used for hoist

Abstract

The invention provides a buffer spring fixing structure used for a hoist. The buffer spring fixing structure comprises a spring base cover plate, screw rods and limiting cover plates. The bottoms of the two ends of the spring base cover plate are fixedly connected with one ends of buffer springs correspondingly, and the other ends of the two buffer springs are fixedly connected with pedestals correspondingly. Limiting structures are connected between the two ends of the spring base cover plate and the pedestals at the corresponding sides. The outer side of each pedestal is fixedly connected with a fixed base, and the top of each fixed base is fixedly connected with a limiting plate. The screw rods sequentially penetrate through the corresponding limiting cover plates and the limiting plates from top to bottom. According to the buffer spring fixing structure used for the hoist, when the construction hoist drops to the buffer springs, the buffer springs suffer from downward impulsive force; at this moment, the buffer springs can only be compressed without shifting, the problem of damage to parts like a suspending cage bottom is effectively avoided, and safety is greatly improved; and moreover, installation is easy and maintenance is convenient.

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a buffer spring fixing structure for a lift. Background technique [0002] The elevator is a kind of mechanical equipment for vertically transporting construction personnel and materials in construction. The elevator has a large load and a fast speed. When it falls out of control and falls to the bottom, it is easy to form a large impact force, which causes damage to the bottom of the elevator cage. If there is a large damage, the best way is to install a buffer device. In the prior art, when the sill height of the outer cage of the hoisting cage is low, the buffer spring is directly placed on the chassis, and a cover plate is placed on it without fixing it. When the elevator bottoms out, the buffer spring is easy to shift and cannot The function of cushioning can easily cause damage to the lower bottom of the hanging cage and other components, and there are certain potenti...

Problems solved by technology

[0003] In view of this, the present invention aims to propose a buffer spring fixing structure for elevators to solve the problem that when the height of the threshold of the outer cage is low, the buffer spring is easy to shift, causing the spring to fail to play a buffer role, and the lower bottom of the cage and other components damage problem
