Abstract
The utility model discloses a compression-resistance telescopic bar, which belongs to the field of timbering equipment and comprises an outer rod. The outer rod is provided with a drill hole; one end of the drill rod is connected with an inner rod through a bolt blocking spring on the drill hole, and the other end thereof is connected with another inner rod though an inner lock or a screw. The bar has certain capacity of compression and deformation resistance and can prevent a brace from being crushed.
Description
Technical field
The utility model relates to the pillar equipment in the engineering.
Background technique
Increase along with the pit mining degree of depth, the ore deposit is pressed increasing, roadway deformation is serious, adopt the interim ventilation equipment of timbering or other support form to crush easily, need to repair again, the waste great amount of manpower and material resources, ruinate ventilation equipment also influences the stability and the reliability of ventilation system.
The model utility content
Task of the present utility model is to provide a kind of material that interim ventilation equipment supporting is depressed in high ore deposit that is used for, and can bear certain pressure, and adapts to certain roadway deformation.On the outer bar boring is arranged, an end of outer bar with block spring and be connected by the bolt in the boring with interior bar, the other end is connected with bar in another by internal lock or screw.On the above-mentioned outer bar a plurality of borings are arranged, its flexible length of can regulate, the other end has two screws, the flexible length of bar in the can regulate the other end.Above-mentioned spring is to be blocked by bolt or pin, and the position of spring can be adjusted in outer tube.
Comprise outer bar, interior bar, spring, boring, pin, bolt, screw, the boring on the outer bar has pin or bolt to block spring, and spring is connected with interior bar, and bar inserts in the outer bar in the other end, is fixed by internal lock or screw.
Above-mentioned spring can be regulated by boring in interior pipe.
The interior bar of an above-mentioned end can be regulated according to the height of supporting.
The utility model has the advantages that simple in structurely, practical, outer bar and interior bar can separate, and be easy to carry, is easy for installation and removal at the scene, can bear certain pressure, and the length of bar can be adjusted, and can adapt to certain roadway deformation, and is better through trial effect.
Description of drawings
Fig. 1 and Fig. 2 are structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described.
Embodiment
The utility model is mainly by interior bar 1, outer bar 2, spring 6, boring 4, bolt 5, screw 3 is formed, flexible rod can be formed (as Fig. 1) by an outer bar 2 and two interior bars 1, also can form (as Fig. 2) by an outer bar 2 and an interior bar 1, bar is about 1.5 meters in general, about 2.0 meters on outer bar, highly higher if (as Fig. 1), can adopt the support pattern of Fig. 1, two interior bars are distinguished the two ends of bar outside, one end is fixed by screw or internal lock and outer bar, bolt 5 fixing springs of one end by passing outer bar 2 link to each other with interior bar 1 by spring 6, and outer bar and interior bar gap are at 1-3mm; If supporting height is not very high, can adopt Guan Yuyi joint outer tube (as Fig. 2) in the joint, bolt 5 passes the suitable boring 4 of outer tube 2, and spring 6 is arranged on the bolt 5, is connected with interior bar 1 by spring 6.The length of interior bar 1 and outer bar 2 can change.
Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skill in the art, according to the utility model done without creatively improving, just should be within protection domain of the present utility model.
Claims (3)
