Abstract
The utility model discloses a blast hole sealing plug, comprising a hollow elastic outer tube and a solid inner tube sheathed in the outer tube, wherein at least two notches extending axially are arranged on the side surface at one end of the outer tube, one end of the inner tube is a conical end which is gradually increased toward the end surface in diameter, outer threads are arranged on the side surface of the other end of the inner tube, the conical end corresponds to one end of the outer tube, which is provided with the notches, the diameter of the end surface of the conical end is larger than the inner diameter of the outer tube, a nut is sheathed at one end of the inner tube, which is provided with the outer threads, the nut is in thread fit with the inner tube, and the diameter of the nut is more than the inner diameter of the outer tube. The blast hole sealing plug is stretched into the opening part of a blast hole for fixing the outer tube, the nut is screwed to drive the inner tube to ascend, and the conical end of the inner tube expands one end with the notches of the outer tube so as to clamp the outer tube on a blast hole wall for fixation, thereby completing the sealing plugging to the blast hole; and the operation process is simple and fast, the filling is firm without using traditional packing materials, and the labor efficiency is improved.
Description
Technical field
The utility model relates to a kind of blast working equipment, is specifically related to a kind of big gun hole sealing plug.
Background technology
Surface mine at first is the perforation operation before bursting work, after the perforation explosive and explosive is put into the big gun hole of having put on, after explosive and blasted material install, need clog the big gun hole, and filling can be selected materials such as stemming or sandstone for use.No matter be artificial filling or machinery filling, the filling process is all comparatively complicated, and requires padding firmly to push, and filling closely in addition, is also noted that protection fuse cord or electric wire in the filling process again; Therefore, existing filling mode wastes time and energy, and labour intensity is big, and efficient is low.
Therefore, need to explore a kind of novel filling equipment, can substitute traditional padding obstruction is sealed in the big gun hole, and simple to operate, and filling is firmly raised labour efficiency.
Summary of the invention
In view of this, the utility model provides a kind of big gun hole sealing plug, and can substitute traditional padding obstruction is sealed in the big gun hole, and simple to operate, filling is firmly raised labour efficiency.
The big gun hole sealing plug of the utility model; Comprise the hollow elasticity outer tube with in be placed in pipe in outer tube solid; Have at least two axially extended breach on said outer tube one end side surface, said interior Guan Yiduan is that other end side is provided with external screw thread to the gradually big conical head of end face diameter; Said conical head and outer tube are provided with the corresponding and conical head end face diameter of an end of breach greater than outer tube diameter, said in pipe be provided with an externally threaded end and be with and its threaded engagement and diameter nut greater than outer tube diameter.
Further, said breach evenly distributes along the outer tube circumferencial direction;
Further, said breach is four;
Further, said interior pipe has the through hole that supplies fuse cord or electric wire to pass vertically.
The beneficial effect of the utility model is: the utility model is stretched into the big gun orifice part, fix outer tube, turn nut; Pipe rises in driving, and the conical head of interior pipe is provided with an end dilating expansion of breach with outer tube, thereby it is fixing that outer tube is stuck on the big gun hole wall; Promptly accomplish the obstruction of sealing to the big gun hole, the operating process simple and fast, filling is firmly; Need not to re-use traditional padding, improved efficiency.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the structural representation (broken section) of the utility model;
Fig. 2 is the user mode figure of the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.
Fig. 1 is the structural representation (broken section) of the utility model; As shown in the figure; The big gun hole sealing plug of the utility model, comprise hollow elasticity outer tube 1 with in be placed in pipe 2 in outer tube 1 solid, have at least two axially extended breach 11 on said outer tube 1 one end side surface; Pipe 2 one ends are to the gradually big conical head 21 of end face diameter in said; Other end side is provided with external screw thread 22, and said conical head 21 and outer tube 1 are provided with corresponding and conical head 21 end face diameters of an end of breach 11 greater than outer tube 1 internal diameter, said in pipe 2 end that is provided with external screw thread 22 be with and its threaded engagement and diameter nut 3 greater than outer tube 1 internal diameter.
As the further improvement of the utility model, said breach 11 evenly distributes along outer tube 1 circumferencial direction; Equally distributed breach makes outer tube evenly expand, and prevents that outer tube is crooked, makes more firm being stuck on the big gun hole wall of outer tube.
In the present embodiment, said breach 11 is four; Certainly, two and above breach can be realized the purpose of the utility model, but the outer tube expansion effect of two breach is not good, should be suitably greater than two.
As the further improvement of the utility model, said interior pipe 2 has the through hole 23 that supplies fuse cord or electric wire 4 to pass vertically; Be convenient to fuse cord or electric wire 4 layouts, and do not influence the obstruction of sealing the big gun hole.
Fig. 2 is the user mode figure of the utility model, and is as shown in the figure, and the utility model is stretched into big gun hole 5 oral areas, fixes outer tube 1; Turn nut 3, pipe 2 rises in driving, and the conical head 21 of interior pipe 2 is provided with outer tube 1 an end dilating expansion of breach 11; Thereby it is fixing that outer tube 1 is stuck on 5 walls of big gun hole, promptly accomplishes the obstruction of sealing to big gun hole 5, the operating process simple and fast; Filling firmly need not to re-use traditional padding, has improved efficiency.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
