Problems solved by technology

[0003] However, as far as the current crane is concerned, the fixed pulley does not have any safety buffer structure, which causes the force of the steel cable on the wheel body of the fixed pulley to increase when the crane lifts the cargo, which is very easy to wear or damage the fixed pulley and the steel cable, affecting the safety of the crane. In normal use, the stability is poor, which increases the cost of using the crane, and the practicability is not high

Embodiment

[0037] Example: please refer to Figure 1 to Figure 11 :

[0038]The present invention proposes a safety shock absorbing device for a crane, comprising: an installation fixing base 1, the installation fixing base 1 is fixedly installed on the top of the boom of the crane, and a safety shock absorbing component is installed inside the installation fixing base 1; The shock assembly is composed of a shock absorber mechanism 2, a control mechanism 3 and an adjustment mechanism 4, and the shock absorber mechanism 2 includes a main shock absorber rod 201, an auxiliary pressure plate 202 and a pulley 203, and the main shock absorber rod 201 is inserted into the mounting base 1. The auxiliary pressure plate 202 is inserted into the interior of the mounting base 1, and the pulley 203 is connected to the top of the main shock-absorbing rod 201 in rotation. At the same time, when the device is hoisted, the instantaneous pressure of hoisting can make the pulley 203 move downward, so that...

Abstract

The invention provides a safety shock absorbing device for a crane, which relates to the technical field of cranes, and includes: an installation fixing seat, a safety shock absorbing component is installed inside the installation fixing seat, and the safety shock absorbing component can be realized by a pulley of a shock absorbing mechanism The guiding and traction effect of the wire rope, at the same time, the damping mechanism can buffer the instantaneous pressure of the wire rope on the pulley during the lifting of the shock-absorbing crane, thereby greatly reducing the wear degree of the pulley and the wire rope when the crane lifts the goods. The device is equipped with a three-stage shock absorption and buffer structure, which can realize the safety shock absorption function when lifting and transporting goods of different weights, and has strong adaptability. When the goods are carried, the force of the steel cable on the fixed pulley body increases, which is very easy to wear or damage the fixed pulley and the steel cable, and the stability is poor, which increases the use cost of the crane.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a safety damping device for cranes. Background technique [0002] Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. It is mainly used for the vertical and horizontal transportation of materials and the installation of building components in the construction of houses. The pulley plays the role of guiding and pulling the wire rope. [0003] However, as far as the current crane is concerned, its fixed pulley does not have any safety buffer structure, which leads to an increase in the force of the wire rope on the fixed pulley body when the crane lifts the goods, which is very easy to wear or damage the fixed pulley and wire rope, affecting the crane's performance. In normal use, the stability is poor, which increases the use cost of the crane, and the practicability is not high. SUMMARY OF THE I...
