Abstract
The utility model discloses an articulated roof-beam forward-extended supporter which comprises a lock, an articulated roof beam and a reinforcing pin. The lock is a piece having atypical profile and provided with a downward-opening port and a laterally-opening port, pin grooves arranged at two sides of the downward-opening port, an anchor rod hole arranged on the top panel, and optionally an anti-falling head arranged at the edge of the top panel. The application of the supporter includes fixing the anchor rod on the roadway top panel by the lock with anchor rod hole in the anchor rod support roadway, or hanging the lock with anti-falling head to the support roof beam in the roof-type anchor rod support roadway; inserting the tail end of the articulated roof beam into the downward-opening port of the lock; and inserting the reinforcing pin for fastening. Since the articulated roof-beam is used as forward-extended supporter, the utility model has light weight and good portability. Additionally, the lock is installed in suspension mode, thus the utility model is easy to mount and demount.
Description
Technical field
The utility model relates to down-hole driving temporary support device.
Background technology
Under down-hole especially coal mine, in the tunnelling,, all to carry out temporary lining for the safety of working.The support pattern approaching with the application is directly to intert very long steel part on the supporting capplce, as i iron, channel-section steel, round steel etc.The steel part that interts is a brace summer with top capplce, along with the carrying out of tunneling constantly moves forward steel part again to work plane.The deficiency of this temporary lining mode is: steel part is oversize too heavy, weight lifting when reach operation inconvenience, as run into the top and easily be not stuck at ordinary times, be difficult to move.
Summary of the invention
The application's purpose is the hinged roof beam type cantilever timbering of a kind of down-hole of design driving usefulness, reaches and moves purpose easy for installation.
For achieving the above object, the application's structure is: it is made up of tapered end, articulated roof beam and reinforcing pin; Tapered end is the member of a special-shaped section, and member has towards a side with towards the opening of below, is processed with pin grooves in the both sides of lower opening, is processed with bolthole on the upper top plate, perhaps is processed with the anticreep head at the bead place of upper top plate.
The application has two kinds of mode of occupation: the one, in roadway supported by bolt, use the tapered end of being with bolthole, and tapered end is fixed on the back with anchor pole; The 2nd, in the shed ding support tunnel, use the tapered end of being with the anticreep head, tapered end is hung on the supporting capplce.Then the articulated roof beam rear end is inserted in the tapered end lower opening, insert the reinforcing pin and tighten up.
Owing to adopt articulated roof beam to make cantilever timbering, so in light weight, conveniently moving; Owing to adopt the underslung mounting means of tapered end, so easy for installation, mobile dismounting is also convenient again.
Description of drawings
Fig. 1 is the front view of the embodiment of the present application 1, and Fig. 2 is the left view of embodiment 1, and Fig. 3 is the front view of the embodiment of the present application 2, and Fig. 4 is the left view of embodiment 2.
Among the figure: 1-anchor pole, 2-nut, 3-tapered end, 4-pin, 5-articulated roof beam, 6-bolthole, 7-pin grooves, 8-anticreep head, 9-capplce.
The specific embodiment
Be further described below in conjunction with the technical scheme of accompanying drawing the application.
As shown in Figure 1 and Figure 2, it is suitable for the bolt-spary supports tunnel.At first process a tapered end 3, tapered end 3 is members of a different in nature section, and its top is to a side opening, and the bottom downwardly facing opening is processed with bolthole 6 on the tapered end top panel, adds to have pin grooves 7 on tapered end lower side panel.During use, tapered end 3 is inserted on the anchor pole head of top boards, tighten up, again articulated roof beam 5 rear ends are pushed the under shed of tapered end, in two pins, 4 insertion pin grooves 7, pound tightly with hammer and to get final product with nut 2.
Move when removing, the pin 4 that pounds with a hammer takes off articulated roof beam 5, assembles next time.
