Hoisting device for heading machine and heading machine with hoisting device

Abstract

The invention relates to a hoisting device for a heading machine and the heading machine with the hoisting device. The hoisting device comprises a conveying track, electric hoists and a trolley conductor, wherein the conveying track penetrates through trailers of the heading machine in the longitudinal direction in sequence and is connected with the tops of the trailers; the electronic hoists are capable of moving on the conveying track in an extension direction of the conveying track; the slide conductor comprises a slide wire track and a current collector; the slide wire track penetrates through the trailers of the heading machine in the longitudinal direction in sequence and is connected with the tops of the trailers; the current collector is connected with the electronic hoists and is capable of sliding in the extension direction of the slide wire track so as to supply power to the electronic hoists; sliding mechanisms are correspondingly arranged on one side or two sides of a joint area of two adjacent trailers; the slide wire track is connected with the trailers through the sliding mechanisms, so that the slide wire track is capable of swinging in the transverse direction relative to the trailers. By adopting the hoisting device of the heading machine, the current collector is not liable to be blocked by a bent part of the slide wire track, and moreover the fatigue of the slide wire track can be greatly alleviated, and thus the service life of the slide wire track can be prolonged.

Description

technical field [0001] The invention relates to the field of tunnel construction machinery, in particular to a hoisting device for a roadheader and a roadheader including the hoisting device. Background technique [0002] In the field of tunnel construction machinery, the tunnel boring machine has the advantages of small environmental impact, fast tunneling speed, and small surface settlement during underground construction, so it is widely used in the construction of underground tunnels. [0003] At present, the hoisting device of the roadheader includes conveying rails that pass through the trailers of the roadheader in sequence along the longitudinal direction, an electric hoist that moves along the guide rails, and a trolley line capable of supplying power to the electric hoist. However, due to the frequent staggering of adjacent trailers when the roadheader is working, the sliding wire track of the trolley line is often repeatedly bent, which not only causes the collect...

AI Technical Summary

Problems solved by technology

However, due to the frequent staggering of adjacent trailers when the roadheader is working, the sliding wire track of the trolley line is often repeatedly bent, which not only causes the collector sliding on the sliding wire track to be easily stuck by the curved part of the sliding wire track , and the sliding track is prone to cracks due to fatigue
