Abstract
The utility model discloses a kind of colliery with pulling off head unit, belonging to pin pulling out device field, comprise nut, pad, stud and steel pipe, the two ends of stud are all threaded, stud is placed in steel pipe, and pad is placed in one end of steel pipe, and nut is spun on the stud of pad side.Colliery of the present utility model is with pulling off head unit, and this apparatus structure simple operations is convenient, and first with tapping tapping screw on broken end, then insert the stud originally pulling off head unit, rotating nut easily can extract the broken end of fracture.
Description
Technical field
The utility model relates to pin pulling out device field, colliery, and specifically, the utility model relates to colliery with pulling off head unit.
Background technology
Subsurface environment is compared with ground environment, and working space is little, and execution conditions are limited.Fully-mechanized mining working often can run into the phenomenon of various jack pipe joint fracture, and for coal mine production safety is considered, the joint of fracture needs to extract in time, now relies on manpower to extract very difficult, directly has influence on back production progress sometimes.As changed a bracket upright post cost close to ten thousand yuan, a working face extraction gets off, often will more several, for colliery management both uneconomical, dangerous again.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device extracting broken end fast and safely.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: colliery is with pulling off head unit, comprise nut, pad, stud and steel pipe, the two ends of described stud are all threaded, stud is placed in steel pipe, pad is placed in one end of steel pipe, and nut is spun on the stud of pad side.
Preferably, described nut has two, and described two nuts are spun on together.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
Colliery of the present utility model is with pulling off head unit, and this apparatus structure simple operations is convenient, and first with tapping tapping screw on broken end, then insert the stud originally pulling off head unit, rotating nut easily can extract the broken end of fracture.
Accompanying drawing explanation
Brief description is made to the content expressed by each accompanying drawing of this description and the mark in figure below:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is thick six rib tapping;
Fig. 3 is thin six rib tapping;
Mark in above-mentioned figure is: 1, nut; 2, pad; 3, steel pipe; 4, stud; 5, screw thread; 6, break end; 7, fixture; 8, thick six rib tapping; 9, thin six rib tapping.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Broken end 6 is stuck in Support joint manually extracts difficulty, and use during this device and first use thick six rib tapping 8 as shown in Figure 2 on the section of broken end 6, attack coarse-pitch thread hole, thick six rib tapping 8 are extracted in coarse-pitch thread hole after accomplishing fluently; Then thin six rib tapping 9 are as shown in Figure 3 used to get thin screwed hole on the basis in coarse-pitch thread hole.
Be illustrated in figure 1 structural representation of the present utility model, the two ends of stud 4 are all threaded 5, and screwed in the fine thread hole beaten on broken end 6 by thin six rib tapping 9 one end of stud 4, stud 4 screws, then steel pipe 3 is enclosed within stud 4, one end of steel pipe 3 is against on fixture 7, and pad 2 is placed on the other end of steel pipe 3, screws in nut 1 outside pad 2, nut 1 has two, two nuts are spun on together, play firm effect, and what prevent nut stripped thread above from affecting broken end 6 extracts effect.With the nut 1 of spanner not section pivot head during use, nut 1 drives stud 4, and stud 4 drives broken end 6 to be extracted by broken end 6.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
