Description
Technical field
The utility model belongs to mechanical anti-dropout fixed equipment, particularly relates to a kind of telescopic anti-drop device.
Background technology
In various construction process, to prevent workpiece from coming off, workpiece is fixed frequently with anti-drop device.By
It is different in construction environment, so common anti-drop device cannot be general, such as in mine uphole to methane drawing device
Fixation, since uplink bore open is small, depth is big, and common anti-drop device can not be stretched into hole, and usually to gas take out
Device is taken to be fixed using single chain, such a fixed form safety coefficient is relatively low.
Utility model content
To overcome the problem of gas draw-out device is fixed in above-mentioned mine, the utility model provides a kind of telescopic anti-dropout
Device.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of telescopic anti-drop device, it is characterised in that：Including screwed pipe, screwed pipe one end is fixedly connected with footstock,
The other end is connected with threaded block, and the footstock and opposite position on the inside of threaded block have been respectively articulated with several supporting rods I and several
Supporting rod II, supporting rod I and the free end of supporting rod II in opposite position are hinged by axis pin, and threaded block side is provided with
Groove, threaded block are put into groove equipped with the spanner that matches, convex emit of spanner, by rotating spanner, to drive threaded block movement, contracting
Distance between short thread seat and footstock, makes supporting rod I be upwardly formed protrusion with supporting rod II.
The screwed pipe is with being then equipped with protrusion in footstock junction, to limit the movement of footstock.
The end that the screwed pipe is equipped with footstock side is equipped with locking nut.
Sealing ring is provided with the locking nut.
The screwed pipe is equipped with connector I equipped with threaded block side end.
The connector I is equipped with detachable connector.
The supporting rod I is 2-4 with II number of supporting rod.
Beneficial effect：The utility model is telescopic anti-drop device, drives threaded block to move by rotating spanner, works as spiral shell
When line seat is with footstock Distance Shortened, supporting rod I is upwardly formed protrusion with supporting rod II, plays anti-off effect；Opposite direction is rotated and pulled
Hand, supporting rod I are upwardly formed projections collapse with supporting rod II, device can be taken out from drilling, reuse the device, reduce
Cost.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings, a kind of telescopic anti-drop device, it is characterised in that：
Including screwed pipe 1,1 one end of screwed pipe is fixedly connected with footstock 2, and the other end is connected with threaded block 3, the footstock 2 and threaded block 3
Inner side opposite position has been respectively articulated with several supporting rods I 4 and several supporting rods II 5, the supporting rod I 4 in opposite position
It is hinged with the free end of supporting rod II 5 by axis pin, 3 side of threaded block is provided with groove, and threaded block 3 is pulled equipped with the spanner 6 that matches
Convex emit of hand 6 is put into groove, by rotating spanner 6, to drive threaded block 3 to move, shorten distance between threaded block 3 and footstock 2, make
Supporting rod I 4 is upwardly formed protrusion with supporting rod II 5.
Above be the utility model basic embodiment, can more than on the basis of further improved, optimized and limited
It is fixed：
Such as, the screwed pipe 1 is with being then equipped with protrusion 7 in 2 junction of footstock, to limit the movement of footstock 2；
Such as, end of the screwed pipe 1 equipped with 2 side of footstock is equipped with locking nut 8；
Further, it is provided with sealing ring 9 in the locking nut 8；
For another example, the screwed pipe 1 is equipped with connector I 10 equipped with 3 side end of threaded block；
Further, the connector I 10 is equipped with detachable connector 11；
Finally, the supporting rod I 4 and II 5 numbers of supporting rod are 2-4.
Technical solution and embodiment and non-limiting cited by the utility model, with the skill cited by the utility model
Art scheme and embodiment are equal or effect same approach is all in the range of the utility model is protected.
