Embodiment Construction

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

[0030] Such as Figure 1-Figure 4 As shown, a transport roadway support traveling mechanism includes an advanced support 1 and a transfer machine transport trough 2, the transfer machine transport trough 2 is an independent structure that removes the transfer machine self-moving mechanism, and the advanced support 1 includes a main frame 3 and Auxiliary frame 4, in the present embodiment, a pair of advanced support is made of four supports, and one or three supports form main frame, and two or four supports form sub-frame, ( figure 2 Among them, the thin line represents the main frame, and the thick line represents the sub-frame) both overlap and fit together, and the overall travel of the leading frame 1 is realized through the alternate travel of the main frame 3 and the sub-frame 4. The base 5 of the main frame and the The transfer m...

Abstract

The invention provides a haulage roadway support advancing mechanism. The haulage roadway support advancing mechanism comprises an advance support and a reversed loader conveying groove, wherein the advance support comprises a main support and an auxiliary support; the main support and the auxiliary support advance alternately to achieve overall advancing of the advance support; a base of the mainsupport is fixed to the reversed loader conveying groove; and a base of the auxiliary support and the reversed loader conveying groove are arranged in a split mode. According to the haulage roadway support advancing mechanism, a self-moving mechanism of a traditional reversed loader is omitted, the reversed loader conveying groove and the main support of the advance support are fixed together, the main support drags the reversed loader conveying groove to move along with advancing of the advance support, pressure-relief-free supporting is achieved, the operation performance is better, the motion relation is simplified, and a floor heave can be effectively controlled.

Description

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