Abstract
The utility model discloses a fore support for a roadway provided with one group of two frames. The fore support comprises a main frame and an auxiliary frame, wherein the main frame and the auxiliary frame both comprise bases, top beams, and upright posts arranged between the bases and the top beams; the auxiliary frame is arranged between open forks of the main frame; the front end of the base of the main frame is hinged with the front end of the base of the auxiliary frame through a push jack; the base at the front end of the auxiliary frame is provided with a frame adjusting jack; both sides of the main frame are respectively hinged with a protective top plate, and the protective top plates are respectively hinged with the top beam of the main frame through side picking jacks; the back end of the top beam of the main frame is hinged with an outrigger, and the outrigger is hinged with the back end of the top beam of the main frame through a back picking jack; and the outrigger is provided with a backwards stretched telescopic beam. The fore support, provided by the utility model, has the advantages that the automation of the fore support is realized, and the safe and effective production of a mining work surface is ensured. According to the utility model, the advance speed of the work surface is accelerated and the efficiency of a fully-mechanized work surface is fully exerted; furthermore, the fore reinforced support is satisfied, and the repeated support of the roadway top plate is avoided.
Description
Technical field
The utility model relates to down-hole fully-mechanized mining working faces end head support, especially relates to two one group of tunnel advance timberings.
Background technology
According to " safety regulations in coal mine " regulation, all emergency exits of coal-face are in the 20 meters scopes in junction, tunnel, must add strong supporting.The head-room of fully-mechanized mining working in this scope must not be lower than 1.8 meters, promptly adopts in the 20 meters scopes in face two lanes and must take the advance support measure.The most of mining area of China coal-face lame advanced supporting mainly carries out supporting with individual prop complexed metal articulated roof beam at present, and this supporting method supporting intensity is low on the one hand, and it is many that individual prop bores the end, returns and removes difficulty; Return on the other hand and all adopt manpower when removing, labour intensity is big, the most important thing is that support cost is high, poor stability.
Summary of the invention
The utility model purpose is to provide two high, safe and reliable one group of tunnel advance timberings of a kind of automaticity.
For realizing above-mentioned purpose, the utility model is taked following technical proposals:
Described two one group of tunnel advance timberings of the utility model comprise body frame and subframe; Said body frame and subframe constitute by base, back timber, the column that is arranged between base and the back timber; Said subframe is arranged on said body frame and opens between the crotch; Body frame base front end is hinged through passing jack and subframe base front end; Subframe front end base is provided with transfers the frame jack; Be hinged with respectively in the both sides of body frame and protect top board, saidly protect that top board is chosen jack through side respectively and the body frame back timber is hinged; Be hinged with outrigger at the body frame top beam rear end, said outrigger through after choose jack and the body frame top beam rear end is hinged; Flexible backward extensible canopy is installed on outrigger.
Between the front and rear of said major and minor base and major and minor back timber, be respectively arranged with two connecting rods and quadric chain.
The utility model advantage is to realize the automation of advance support, ensures the safe and efficient production of exploitation work plane.When moving frame, be fulcrum, handle the subframe column and make subframe break away from top board a little, pass jack and stretch out, the subframe reach with the body frame.Handle the subframe column then and make the subframe back timber prop up top board, and make column reach setting load; Handling the body frame column and make body frame break away from top board a little, is fulcrum with the subframe, passes the jack withdrawal, the body frame reach.The subframe front end is provided with one and transfers the frame jack, the left and right sides position of adjustment support in the tunnel in the support walking process.Because set cap is longer, the stabilizing mechanism of support is arranged on two ends, and the rear end is provided with quadric chain, and front end is set up one two linkage, has strengthened the anti-twisting property and the stability of support.The back timber of support, base adopt the segmented box section, and be simple and reliable for structure.The body frame rear end is provided with outrigger and extensible canopy, and extensible canopy is positioned at outrigger, and is capable of expansion and contraction during work, helps control.Body frame back timber both sides are provided with protects top board, can protect pedestrains safety.This novel cost of winning that reduced has been accelerated the fltting speed of work plane, has given full play to the usefulness of fully mechanized coal face; Can satisfy and add strong supporting in advance, can avoid back to support repeatedly again.

The specific embodiment
Like Fig. 1,2, shown in 3, described two one group of tunnel advance timberings of the utility model comprise body frame and subframe; Said body frame and subframe constitute by base, back timber, the column that is arranged between base and the back timber; Said subframe is arranged on said body frame and opens between the crotch; Body frame base front end is hinged with subframe base front end through passing jack 1; Subframe base front end is provided with transfers frame jack 2; Be hinged with respectively in the both sides of body frame back timber and protect top board 3, saidly protect top board 3 to choose jack 4 through side respectively hinged with body frame back timber 5; Be hinged with outrigger 6 in body frame back timber 5 rear ends, said outrigger 6 through after to choose jack 7 hinged with body frame back timber 5 rear ends; Flexible backward extensible canopy 8 is installed in outrigger 6.Between the front and rear of major and minor base and major and minor back timber 9, be respectively arranged with two linkages 10 and quadric chains 11.
Claims (2)
1. two one group of tunnel advance timberings comprise body frame and subframe; Said body frame and subframe constitute by base, back timber, the column that is arranged between base and the back timber; It is characterized in that: said subframe is arranged on said body frame and opens between the crotch; Body frame base front end is hinged with subframe base front end through passing jack (1); Subframe base front end is provided with transfers frame jack (2); Be hinged with respectively in the both sides of body frame and protect top board (3), saidly protect top board (3) to choose jack (4) through side respectively hinged with body frame back timber (5); Be hinged with outrigger (6) in body frame back timber (5) rear end, said outrigger (6) through after to choose jack (7) and body frame back timber (5) rear end hinged; Flexible backward extensible canopy (8) is installed on outrigger (6).
