Abstract
The invention discloses a tool used in coal mine coal road construction, in particular relates to a telescopic type front canopy support used for safety and protection after blasting of coal road. The telescopic type front canopy support comprises a plurality of supports (1) which are connected together by a splint (3) at equal distance, an automatic conveyor is fixed at the two sides in the support (1) by a suspension fixing device, and a movable supports (5) of front canopy are superposed together and arranged on the fixed seat (6) at the front end of the sliding shaft (4) of the automatic conveyer. The invention designs the automatic conveyer and a movable suspension fixing device, supports used for safety and protection after blasting of coal road can be automatically conveyed, the supports are firmly fixed on the erected canopy frame, the prepared frame beam support is moved forward by utilizing spiral thrust, so as to protect a roof, labor intensity of worker is relieved, safety coefficient in working period is improved in fault fracture and roof fracture areas and treatment of roof collapse, use is convenient, and the invention can be widely applied to joist steel and arc steel supports.
Description
Technical field: the instrument that uses when the present invention relates to the coal road construction of a kind of colliery specifically is the telescopic type front canopy support that safeguard protection was used after coal road was blown out.
Background technology: at present, in the construction of colliery, need dig needling after driving is blown out, brushing does not have the front-probe support operation abnormally dangerous, so frame canopy driving must have front-probe support.The front-probe support of i iron frame in the past, usefulness be the long beam of π type, use that comparatively heaviness is inconvenient again.And the front-probe support problem of U type frame is never solved preferably.In the past put on the shelf the front-probe support of canopy all is that the worker holds up or presses with pipe, inefficiency, and construction speed is slow, the more important thing is to have had a strong impact on construction safety.
Summary of the invention: the invention provides a kind of labor strength that alleviates, improve the telescopic type front canopy support of operating safety factor.It comprises that several supportings 1 are equidistantly linked together by clamping plate 3, and automatic conveying device is fixed on both sides in the supporting 1 by suspended and fixed device, and forestope activity supporting 5 activities of being stacked are placed on the holder 6 of movable axis 4 front ends of automatic conveying device.Because the present invention has designed automatic conveying device and activity suspended and fixed device; can carry out automatic transport to blowing out the supporting that the back coal road carries out safeguard protection; firmly be fixed on the frame that has set up; utilize spiral thrust that top board is protected in ready capplce supporting reach, alleviated working strength of workers, for crossing tomography; in roof cracking band and the processing roof fall process; improved the safety factor of duration of work, and easy to use, can be widely used in i iron and the supporting of arc steel.

The specific embodiment; Shown in Figure 5 as Fig. 1 Fig. 2 Fig. 3 Fig. 4, several supportings 1, be U type shape or i iron, equidistantly link together by clamping plate 3, automatic conveying device is fixed on both sides in the supporting 1 by suspended and fixed device, forestope activity supporting 5 or the i iron activity supporting activity of being stacked are placed on the holder 6 of movable axis 4 front ends of automatic conveying device, and the conveying front canopy support that mainly plays activity safety is to the precalculated position.
Shown in Figure 4 as Fig. 1 Fig. 2 Fig. 3, in sleeve pipe 2, preceding upper shield 23 is fixed on sleeve pipe 2 front ends by spring clip 16 and sealing mat 24 to automatic conveying device by movable axis 4 heads; Back upper shield 15 is fixed on sleeve pipe 2 rear ends by spring clip 16 and bearing 17 and cover plate, and and power transmission shaft 19 flexibly connect; Screw rod 21 heads are in movable axis 4, and movable axis 4 is 180 ° two keyways 22, are 180 ° by two hold-down screws 25 and are fixed on sleeve pipe 2 front ends, and tank filler sleeve 20 installs at sleeve pipe 2 middle parts, and communicates with screw rod 21; Power transmission shaft 19 rear ends are square toes 18, and flexibly connect with crank 7, and front end and screw rod 21 flexibly connect, and mainly play the automatic transport front canopy support.
Shown in Figure 6 as Fig. 1 Fig. 2 Fig. 5, suspended and fixed device is connected fixed head 14 both sides by two axle beds 29, and reinforcing rib 28 is welded on two axle beds, 29 upper ends, and pulling seat 26 is movably connected in axle bed 29 two ends by steady pin 27, pull bar 8 is movably connected in pulling seat 26 upper ends, and the fixed mechanism device is at fixed head 14 middle parts; Fixed mechanism is fixed on movable sleeve 10 upper ends by fixing supporting plate 9, pressure bearing 32, bearing 30 by the end cap fastening devices in movable sleeve 10, standing screw 12 flexibly connects with the swivel nut 11 that is fixed on lower end in the fixed head 14, its upper end is connected with pressure bearing 32, bearing 30, following end device one transverse slat bar 13 mainly works to hang fixedly automatic conveying device.
In operation, earlier the pull bar of suspended and fixed device is suspended in the front and back end supporting that fixes, adjust spacing, firm fixing of automatic conveying device, then forestope activity supporting is placed on the holder of movable axis front end, shake handgrip, forestope activity supporting is transported to the precalculated position, position fixing getting final product.
