Steel wire rope interference preventing device of dynamic compactor, cantilever crane of dynamic compactor and dynamic compactor

Abstract

The invention relates to a steel wire rope interference preventing device of a dynamic compactor, a cantilever crane of a dynamic compactor and a dynamic compactor. The steel wire rope interference preventing device of the dynamic compactor comprises a rope limiting rack, and further comprises a T-shaped rack, wherein three end portions of the T-shaped rack are connected to the rope limiting rack, respectively, so that two moving channels allowing two steel wire ropes to pass through separately are formed. The steel wire rope interference preventing device of the dynamic compactor provided by the invention is capable of effectively preventing two lifting ropes from kinking with each other and from hooking on to the cantilever crane during humping.

Description

technical field [0001] The present invention relates to the field of engineering machinery, and in particular to an anti-steel rope interference device for a dynamic tamping machine, a dynamic tamping machine arm frame provided with the anti-steel wire rope interference device for a dynamic tamping machine, and a dynamic tamping machine provided with the dynamic tamping machine arm frame. Background technique [0002] With the acceleration of urbanization in our country, a large number of land reclamation and land reclamation projects have been carried out, and the collapsible loess area and soft clay area are widely distributed in our country, so the dynamic compaction construction machinery will develop into large-scale and serialized . For the dynamic tamping machine with large ramming energy, in order to increase the lifting speed of the rammer, a double hoisting mechanism is often used, so that there are two hoisting wire ropes above the boom. Due to the sudden release...

AI Technical Summary

Problems solved by technology

Due to the sudden release of the rammer during the dynamic compaction operation, the rammer falls freely, and the steel wire rope connected to the rammer will still provide an upward rebound force equivalent to the gravity of the rammer due to inertia at the moment the rammer is released, resulting in irregularities. The rebound and jumping of the two wire ropes are prone to twisting during the rebound and jumping process, and they may even jump to the other side of the jib and hang together with some parts of the jib, which affects work efficiency and safety.

[0003] like figure 1 As shown, at present, many bow frames 2' are installed on the jib frame 1' on the dynamic compaction machine, and the steel wire rope 3' passes through the bow frame 2' when in use, so as to limit the jumping range of the lifting steel wire rope 3'

[0004] Installing several bow-shaped frames on the jib can prevent the hoisting wire rope from being hooked to some parts of the jib, which is very effective for the case of a single hoisting rope; but for the case of double hoisting ropes, since the two ropes are Over the bow frame, so it is impossible to prevent the two ropes from being twisted
