Abstract
The utility model discloses a pull bar structure, comprising a middle seat. The bottom of the middle seat is connected to a connection shaft, and the lower part of the connection shaft is formed with external threads. The top part of the middle seat is connected to a rod base having a through hole. A reinforcement block is disposed between the surface of the middle seat and the two side walls of the rod base. Protruding points are disposed on the inner wall of the through hole of the rod base. The pull bar structure is simple in structure and easy in realization, and is capable of effectively resolving the problem that a pull bar is easy to be broken due to low strength, prolonging service lifetime of the pull bar, and improving safety of coal mine production.
Description
Technical field
The utility model relates to mining fitting field, is specially a kind of bracing structure.
Background technique
Mining is the important means that realizes collection of resources, and wherein coal mining is to obtain resource indispensable activity in production in colliery in the modern energy industry.Need various mechanical engagement in the Modern coal mines exploitation, to save manpower.Commonly usedly in coal mining realize through pull bar that to pull bar the connection of stay cord is fixed, the pull bar intensity of existing technology is lower, and stay cord passes when stretching behind the pull bar through hole and be prone to skid, and influences the down-hole proper functioning.
The model utility content
The utility model purpose provides a kind of bracing structure, and is low to solve existing technology pull bar intensity, is prone to problem of slip after penetrating stay cord.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of bracing structure; Comprise middle base; It is characterized in that: said middle base bottom is connected with the coupling shaft that is shaped to one with middle base, and said coupling shaft bottom forms outside thread, and the middle base top is connected with the pole socket that is shaped to the bulk of one with middle base; Said pole socket top is shaped to semicircle shape; Have through hole near the semicircle shape top in the pole socket, be welded with reinforced block through explosion welding respectively between said middle base seat surface and the pole socket two side, the through-hole wall of said pole socket is provided with a plurality of salient points along the through hole circumferential arrangement.
Described a kind of bracing structure is characterized in that: said reinforced block is the right angle trigonometry piece, and two right angle faces of reinforced block are welded as a whole through explosion welding with middle base seat surface, pole socket sidewall respectively.
The utility model is simple in structure, is easy to realize.The coupling shaft that the middle base bottom connects is fixed on the object that needs pulling; Realize being screwed together fixing through the outside thread of coupling shaft; Stay cord is enclosed within the through hole of pole socket, and pole socket is for being shaped to the block seat of one with coupling shaft, and the pole socket sidewall also and be welded with reinforced block through explosion welding between the middle base; Can improve the intensity of whole pull bar, the salient point that in through hole, is provided with can effectively prevent to skid relatively between stay cord and the pole socket.The utility model can effectively solve pull bar because intensity is hanged down the problem of easy-rupturing, the working life of having improved pull bar, the Security that has also improved Coal Production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1.A kind of bracing structure; Comprise middle base 1; Middle base 1 bottom is connected with the coupling shaft 2 that is shaped to one with middle base 1, and coupling shaft 2 bottoms form outside thread 3, and middle base 1 top is connected with the pole socket 4 that is shaped to the bulk of one with middle base 1; Pole socket 4 tops are shaped to semicircle shape; Have through hole 5 near the semicircle shape top in the pole socket 4, be welded with reinforced block 6 through explosion welding respectively between middle base 1 seat surface and pole socket 4 two sides, through hole 5 inwalls of pole socket 4 are provided with a plurality of salient points 7 along the through hole circumferential arrangement.Reinforced block 6 is the right angle trigonometry piece, and two right angle faces of reinforced block 6 are welded as a whole through explosion welding with middle base 1 seat surface, pole socket 4 sidewalls respectively.
