Abstract
The utility model discloses a top beam telescopic driving working face temporary timbering support which comprises a four-column front frame, a four-column rear frame and a hydraulic system. Two pushing jacks are arranged between the front frame and the rear frame. Main body structures of the front frame and the rear frame consist of two longitudinal frames and two cross beams in a connecting mode. Each longitudinal frame comprises a top frame, a base and telescopic hydraulic side columns on two sides. Two pushing jacks are respectively pulled on the base of the front frame and the rear frame. Multiple sleeve type telescopic longitudinal top beams are respectively arranged on the top faces of the cross beams of the front frame and the rear frame, and the front ends of inner pipes of the longitudinal top beams of each frame are connected through connecting rods. The top faces of the cross beams of the front frame and the rear frame are further respectively provided with top beam telescoping jacks. The top beam telescopic driving working face temporary timbering support can remarkably improve the driving construction speed and safety and provide technical support or quick and safe driving.
Description
Technical field
The utility model relates to roadway head temporary lining equipment.
Background technology
At present, the temporary lining form that down-hole driving face adopts is mainly " post of attaching the names of pre-determined candidates " supporting and front canopy support, all there is the major defect of the aspects such as supporting intensity is very low, supporting area is minimum, supporting effect is bad, poor stability in these easy temporary linings, can not effectively ensure the safety of driving face, can not adapt to the needs of fully-mechanized digging machine fast and safe construction, cause average drill footage per month lower, the digging anxiety that continues.For this reason, on market, also there is portable falsework, but complex structure heaviness, mobile inconvenience.Therefore, be sought after a kind of simple in structure, light temporary support for drivage face support.
Summary of the invention
The purpose of this utility model is the deficiency for solving traditional temporary lining mode in tunnelling, designs a kind of simple in structure, light temporary support for drivage face support.
For reaching above-mentioned purpose, the technical scheme that the utility model is taked is:
The telescopic temporary support for drivage face support of a kind of back timber, it is characterized in that, it comprises a four-column type side arm and a four-column type after-frame, is provided with two advancing jacks between side arm and after-frame, under advancing jack effect side arm and after-frame can mutually draw close or away from; The agent structure of side arm and after-frame is all to be connected to form by two longitudinal framings and two crossbeams; Described longitudinal framing comprises the side column of top frame, base and both sides, and side column is telescopic hydraulic vertical prop; Two advancing jack difference tractives are on the base of side arm and after-frame; Be arranged with respectively by the flexible rnnning bar of several bushing types at the crossbeam end face of side arm and after-frame, the inner tube front end of the rnnning bar of every connects together with connecting rod; Also be respectively equipped with the flexible jack of back timber at the crossbeam end face of side arm and after-frame, the flexible jack of back timber makes rnnning bar realize Telescopic when flexible; It also comprises the hydraulic system being made up of hydraulic power unit and hydraulic valve bank, the flexible jack of the lifting of the telescopic hydraulic vertical prop of hydraulic valve bank control and advancing jack and back timber flexible.
Operating principle of the present utility model is, when digging laneway, be arranged under the empty top of driving face, operation hydraulic valve bank rises telescopic hydraulic vertical prop, make the rnnning bar of two be close to back, and in stress, playing temporary lining effect, constructor tunnels and permanent support work under the shielding of support; Now have two kinds of situations: the one, side arm and after-frame are mutually close, the 2nd, side arm and after-frame mutually from away from, mutually from away from time should ensure after-frame rnnning bar stretch out and withstand two top boards between only.In the time that after driving, empty top appears in front, the rnnning bar that operates in time side arm stretches out and withstands top board, or in time to reach frame.
To reach when frame, as side arm and after-frame in mutually near state, should make after-frame push away side arm, as side arm and after-frame in from away from state, should make side arm draw after-frame.While pushing away side arm, operate hydraulic control valve group, the retraction of side arm rnnning bar, telescopic hydraulic vertical prop are declined no longer stressed, by advancing jack, side arm is pushed away forward to certain distance, then side arm is risen in stress; While drawing after-frame, the telescopic hydraulic vertical prop of after-frame declines no longer stressed, draws after-frame to draw close to side arm, then after-frame is risen in stress by advancing jack; Often pull or promote once to complete and necessarily move frame distance, said process until be advanced to the empty top of work plane place, carries out the temporary lining of next circulation repeatedly.
The utility model is a kind of new driving face mechanization temporary lining equipment; Because it is four pylon bodies, driving workman has improved supporting intensity and the supporting area of temporary lining, reaches the complete supporting of driving face top board, and driving workman can, at trouble free service under frame, avoid human casualty accident; Because it is the assembly of frame before and after, can automated movement, and rnnning bar is scalable, is convenient to neatly immediate support top board as the case may be, promote the parallel operations of driving and supporting operation; Thereby increase substantially tunneling construction speed and safety, for realizing fast, tunneling technical support is provided safely.

Detailed description of the invention:
The telescopic temporary support for drivage face support of back timber as Figure 1-3, it comprises a four-column type side arm 1 and a four-column type after-frame 2, between side arm 1 and after-frame 2, be provided with two advancing jacks 3, under advancing jack 3 effect side arm 1 and after-frame 2 can be drawn close mutually or away from; The agent structure of side arm 1 and after-frame 1 is all to be connected to form by two longitudinal framings and two crossbeams 8; Described longitudinal framing comprises the side column of top frame 6, base 4 and both sides, and side column is telescopic hydraulic vertical prop 5; Two advancing jack 3 difference tractives are on the base 4 of side arm 1 and after-frame 1; Be arranged with respectively the flexible rnnning bar 7 of several bushing types at crossbeam 8 end faces of side arm 1 and after-frame 1, the inner tube front end of the rnnning bar 7 of every connects together with connecting rod 10; Also be respectively equipped with the flexible jack 9 of back timber at crossbeam 8 end faces of side arm 1 and after-frame 2, the flexible jack 9 of back timber makes rnnning bar 7 realize Telescopic when flexible; It also comprises the hydraulic system (not shown in FIG.) being made up of hydraulic power unit and hydraulic valve bank, the flexible jack of the lifting of the telescopic hydraulic vertical prop of hydraulic valve bank control and advancing jack 3 and back timber flexible.
