Embodiment Construction

[0029] The technical solutions of the present invention will be further described in detail below through specific embodiments.

[0030] like Figure 1-Figure 4 As shown, a transport roadway supporting and traveling mechanism includes an advanced support 1 and a loader transport trough 2, and the loader transport trough 2 is an independent structure from which the self-moving mechanism of the loader is removed, and the advanced support 1 includes a main frame 3 and Auxiliary frame 4, in this embodiment, a pair of advanced brackets is composed of four brackets, one or three brackets form a main frame, and two or four brackets form a subframe, ( figure 2 , the thin line represents the main frame, and the thick line represents the sub-frame) The two overlap and fit together, and the main frame 3 and the sub-frame 4 alternately travel to realize the overall travel of the advanced bracket 1. The base 5 of the main frame is connected to The transport tank 2 of the loader is welded...

Abstract

The present invention provides a transport roadway support and traveling mechanism, which includes an advance support and a transport trough of a transfer machine, the advance support includes a main frame and a sub-frame, and the main frame and the sub-frame alternately travel to realize the overall advancement of the advance support, The base of the main frame is fixed to the transport tank of the transfer machine, and the base of the sub-frame is separately arranged from the transport tank of the transfer machine. The transport roadway support travel mechanism cancels the self-moving mechanism of the traditional transfer machine, and fixes the transport slot of the transfer machine and the main frame of the advanced support together. With the advancement of the advanced support, the main frame drags the transport slot of the transfer machine to move together. Realize no pressure relief support, better operability, simplified motion relationship, and effective control of the bottom drum.

Description

technical field [0001] The invention relates to the field of fully mechanized mining in coal mines, in particular to a supporting and traveling mechanism for a transport roadway. Background technique [0002] The strengthening support (including end support and advanced support) of the transportation roadway in the fully mechanized mining and fully mechanized caving face of coal mines has always been an important link affecting the safe and efficient mining of coal. Within 20m of the connection between the exit and the roadway, support must be strengthened; the "Notice of the State Coal Mine Safety Supervision Bureau on Strengthening the Prevention and Control of Coal Mine Rock Burst" stipulates that mines with rock burst regulations and coal mining face with impact danger are safe exits The advanced support range at the connection with the roadway shall not be less than 70 meters, and the advanced support range at the connection between the safety exit and the roadway of th...
