Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is one embodiment of the utility model, it includes nut 1, backing plate 2, chapped pipe 3, resistance plug 4, anticreep
Plug 5 and extension rod 6.The nut 1 and backing plate 2 are mining plain nut and backing plate.The chapped pipe 3 is sectional shape
Steel pipe, both ends be circular cross section and circular inner hole；Center section is ellipse equipped with one section of section and endoporus is ellipse
Special-shaped portion 31.The center section of chapped pipe 3 can also be equipped with multistage abnormity portion 31, as shown in Figure 2.
The endoporus of one end of chapped pipe 3 is equipped with internal thread, for being spirally connected with anticreep plug 5.The outer surface of the other end has outer
Screw thread, external screw thread match with nut 1, which is equipped with backing plate 2, and backing plate 2 is located at 1 inside of nut.Described 4 one end of resistance plug is cone
Platform shape, the other end are cylinder, and threaded hole is equipped at center.4 taper type end of resistance plug is mounted on 3 endoporus of chapped pipe inwardly
Interior, the diameter of the diameter and the circular inner hole of chapped pipe 3 of resistance plug 4 matches.
One end of the anticreep plug 5 is taper type, and the other end is cylinder, and cylindrical portion is arranged with external screw thread, anticreep
It fills in 5 taper type ends inwardly to pacify in 3 endoporus of chapped pipe, anticreep plug 5 is spirally connected with chapped pipe 3.It wears one end of extension rod 6
Cross the screw hole of anticreep plug 5 and resistance plug 4.
The process and assemble process of the utility model and the large deformation mechanism of action：
1. component is processed：Process extension rod 6.The rod-shaped steel with some strength is selected to process its one end outer
Screw thread, and carry out intensive treatment in thread segment part.Processing profiled steel pipe 3.Choose rigidity and the larger circular steel of intensity
Pipe is processed as ellipse by one section among steel pipe by hot rolling technology or adds along in the axial direction of steel pipe at interval of certain distance
One section of ellipse of work, and both ends are still round steel pipe.The minimum diameter in oval section face will match with the diameter of extension rod.Process anticreep plug 5.The material for selecting rigidity larger is processed as the open circles frustum shape with certain length, in cylinder portion
Exceptionally surface processing external threads, match with the internal thread of described 3 one end of chapped pipe, and internal diameter is straight with the extension rod 6
Footpath matches.Resistance plug 4 is processed, the similary material for selecting rigidity larger is processed as the open circles taper type with certain length
