Abstract
The utility model discloses a temporary support device for coal mine heading, belonging to technical field of roof supports. The support device comprises a supporting rod, a connecting piece and a cylinder, wherein a fixing device is installed at one end of the supporting rod and the other end of the supporting rod is connected with the cylinder. An air inlet is arranged on the cylinder. A control valve is installed at the opening of the air inlet. An anti-slipping leg is installed at the bottom of the piston rod of the cylinder. When in working, the end of the supporting rod at which the fixing device is installed is placed on a working surface which is blasted just now, the control valve is connected with an external pressure pipe, the cylinder obtains pressure, the piston rod stretches out to enable the supporting rod to hold up against a roof and thereby the effective temporary support for coal mine heading is realized. The utility model has the advantages of simple structure, high safety and convenience and good supporting effect.
Description
Technical field
The utility model relates to the roof timbering technical field, specifically is a kind of colliery driving temporary lining device, is mainly used in the temporary lining of blasting work face top board just.
Background technology
Dropping easily hurts sb.'s feelings endangers miner's life because firm explosion balkstone becomes flexible, so the top board after the digging laneway explosion of colliery needs anchor pole and the supporting of net sheet.The way that solves is at first to adopt temporary lining, what use at present is inserted-link type temporary lining device, after the explosion inserted link one end is inserted in and reserves the eyeground, the other end is fixing by hook, one end of hook welds the good anchor pole leading screw in a cap nut and rear supporting and is connected, and an end of inserted link is placed in the hook.Because the uneven in addition backing plate sheet of top board can't carry out bolt support sometimes, and the permanent position do not have leeway, so supporting effect is bad.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, the utility model provides a kind of colliery driving temporary lining device, has overcome above-mentioned inserted-link type supporting device unsafe factor.
The utility model is realized with following technical scheme: a kind of colliery driving temporary lining device comprises pressure pin, connector and cylinder; One end of pressure pin is equipped with fastening devices, and the other end is connected with cylinder by connector; Have air inlet on cylinder, the opening part of air inlet is equipped with control valve; Piston rod bottom at cylinder is equipped with non-slip feet.
Operating principle is: that end that pressure pin is equipped with fastening devices is placed on the work plane of firm explosion, the other end is connected with cylinder by connector, make top power belong to top board to the 50-55 degree cylinder angular adjustment, control valve is connected with the external pressure pipe, thereby cylinder must be pressed, piston rod stretches out and makes the dried top board that withstands of holder, has realized effective temporary lining of colliery driving.
The beneficial effects of the utility model are: simple in structure, safe ready, supporting effect is good.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structure chart.
Among the figure: 1, fastening devices, 2, pressure pin; 3, connector; 31, connecting axle; 32, junction plate; 4, handle; 5, air inlet; 6, cylinder; 61, piston rod; 7, non-slip feet; 8, control valve.
The specific embodiment
As shown in drawings, driving temporary lining device in colliery is made up of pressure pin 2, connector 3 and cylinder 6, and an end of pressure pin 2 is equipped with fastening devices 1, and the other end is connected with cylinder 6 by connector 3; Connector 3 comprises a connecting axle 31 and junction plate 32; One end of junction plate 32 adopts bearing pin to be connected with connecting axle 31, and the other end adopts bearing pin to be connected with cylinder 6; Pressure pin 2 adopts bearing pin to be connected with connecting axle 31.Connecting axle 31 is as the tie point of pressure pin 2 and cylinder 6, and pressure pin 2 can take off and make the eyelid retractor fitting operation convenient like this.Have air inlet 5 on cylinder 6, the opening part of air inlet 5 is equipped with control valve 8, and control valve 8 is in opening always.The handle 4 that is used for cylinder 6 angles is installed on cylinder 6, can simply regulates the angle of cylinder 6 like this.Piston rod 61 bottoms at cylinder 6 are equipped with non-slip feet 7, can prevent the harm that the ground injustice causes the eyelid retractor shakiness to be brought.
The course of work: at first pressure pin 2 and cylinder 6 separately are transported to and meet head on, be installed together by connector 3 again; That end that then pressure pin 2 is equipped with fastening devices 1 is placed on the work plane of firm explosion, the angle that regulates cylinder 6 by handle 4 makes top power belong to top board, the position that fixes non-slip feet 7 is connected control valve 8 again with the external pressure pipe, at this moment 6 piston rod 61 stretches out in the cylinder, makes pressure pin 2 hold the crag or the coal cinder of top board firmly.
