Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The purpose of this utility model is to provide one kind and can depressurize unload-type individual prop base mechanism, to solve prior art
The problem of presence, facilitates the decompression of individual prop to unload.
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body implementation method is described in further detail to the utility model.
Embodiment one：
The present embodiment provides one kind and can depressurize unload-type individual prop base mechanism, including base plate 1, stationary wedge branch are sat in bottom
The two ends of block 2 and removable wedge shape bearing piece 3, stationary wedge bearing piece 2 and removable wedge shape bearing piece 3 are respectively provided with an earclip
6, the earclip 6 at the two ends of stationary wedge bearing piece 2 is different from the height of the earclip 6 at the two ends of removable wedge-shaped bearing piece 3, stationary wedge branch
Block 2 and removable wedge shape bearing piece 3 are symmetrical arranged, the earclip 6 at the two ends of stationary wedge bearing piece 2 and the removable two ends of wedge-shaped bearing piece 3
Overlapped at earclip 6, and connected by screw rod 4, nut 5 at earclip 6.
The upper surface of the upper surface of stationary wedge bearing piece 2 and removable wedge shape bearing piece 3 is in the semicircle conical surface, stationary wedge branch
Block 2 and removable wedge shape bearing piece 3 are symmetrical arranged and form an assembly after being linked together by bolt, nut 5, the assembly
Upper surface is in circular conical surface 7.
Embodiment two：
The embodiment is made that further improvement on the basis of embodiment one, and it includes all interior of embodiment one
