Abstract
The utility model discloses a device capable of enabling a roadway support to rotate by 360 degrees to adapt to a top-plate top beam. The device comprises a column cap and a column cap cover plate which are connected with each other, a hemispherical column nest is arranged on the column cap, a through hole is arranged on the column cap cover plate, the inner surface of the through hole is a spherical surface identical with the column nest in curvature radius, the column cap is welded on the top beam, a spherical head at the top end of a vertical column is abutted against the column nest, and the column cap cover plate movably locks a column head of the vertical column at the column nest. The device is capable of enabling the top-plate top beam to rotate around the column head by 360 degrees, convenient to mount and demount and safe to use.
Description
Technical field
The utility model relates to a kind of coal mine roadway bracket component, relates in particular to a kind of excavation support and adapts to 360 ° of rotatable devices of irregular top board back timber.
Background technology
The major function of coal mine hydraulic supporting is the load of bearing and transmitting top board and be caving rock, plays carrying effect.First the position of bearing load is the cap of back timber and the needling of base.Yet the tunnel majority in mine is irregular concavo-convex top board, thereby this just requires the set cap cap using in tunnel can not only bear roof toad and can effectively around the rotation of column column cap, make back timber can adapt to the irregular top board in tunnel, final more effective management back, to the disposable supporting of top board, ensure safety in production, the High-efficient Production of coal-face.
In prior art, the back timber of excavation support can only reach front and back and left-right rotary transfers the irregular top board that adapts to tunnel, but such structure still can not reach the ideal effect to the comprehensive supporting of the irregular top board in tunnel.
Utility model content
The purpose of this utility model is to provide a kind of excavation support and adapts to 360 ° of rotatable devices of irregular top board back timber.
The purpose of this utility model is achieved through the following technical solutions:
Excavation support of the present utility model adapts to 360 ° of rotatable devices of irregular top board back timber, comprise interconnective cap and cap cover plate, described cap is provided with hemispherical needling, and described cap cover plate is provided with through hole, and the inner surface of described through hole is and the sphere of described needling with radius of curvature.
The technical scheme being provided by above-mentioned the utility model can be found out, the excavation support that the utility model embodiment provides adapts to 360 ° of rotatable devices of irregular top board back timber, owing to comprising interconnective cap and cap cover plate, cap is provided with hemispherical needling, cap cover plate is provided with through hole, the inner surface of through hole is and the sphere of needling with radius of curvature, can by cap cover plate by the column cap livelock of column at needling place, can realize set cap and do 360 ° of big angle rotaries around column cap, easy accessibility, is used safety.

The specific embodiment
To be described in further detail the utility model embodiment below.
Excavation support of the present utility model adapts to 360 ° of rotatable devices of irregular top board back timber, its preferably the specific embodiment be:
Comprise interconnective cap and cap cover plate, described cap is provided with hemispherical needling, and described cap cover plate is provided with through hole, and the inner surface of described through hole is and the sphere of described needling with radius of curvature.
Described cap is welded on back timber, and the bulb on column top is against on described needling, and on described cap cover plate, the sphere of through hole is pressed in the side lower part of described bulb.
Described cap cover plate is the structure from the split of described through hole center line.
Described cap cover plate is fixed on described cap with bolt, nut and the packing ring of M30.
Excavation support of the present utility model adapts to 360 ° of rotatable devices of irregular top board back timber, not only can guarantee the supporting intensity requirement of back timber, and can also make excavation support back timber around 360 ° of rotations of column column cap, thereby be better than traditional excavation support back timber can only before and after and the limitation of left rotation and right rotation, better adapt to the irregular top board in tunnel, reach desirable supporting effect.
Specific embodiment:
As shown in Fig. 1 a, 1b, 1c, it is the cap in the utility model.As shown in Fig. 2 a, 2b, it is the cap cover plate in the utility model.
As shown in Figure 3, cap is welded on back timber, after bracket assembled, cap cover plate is fixed on cap with bolt, nut and the packing ring of M30.
As shown in Figure 4, back timber is around 360 ° of rotations of column column cap.
The utility model with cap cover plate by the column cap livelock of column at needling place, can realize set cap and do 360 ° of big angle rotaries around column cap, easy accessibility, is used safety.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
