Abstract
The invention belongs to the technical field of blast holes for the blasting of mines, and particularly relates to a hole plugger for underground upward blast holes. The hole plugger for the underground upward blast holes consists of an elastic rubber sleeve and an elastic rubber pad which is abutted against the end face of the elastic rubber sleeve, wherein a group of inclined bosses are arranged on the outer surface of one end part of the elastic rubber sleeve uniformly, and a connecting column is arranged on the other end face of the elastic rubber sleeve; a through hole which is fixedly connected with the connecting column and an opening which is communicated with an inner hole of the elastic rubber sleeve are formed on the elastic rubber pad; the outer surfaces of a group of inclined bosses are in a circular arc shape, and the inclined bosses are 10 to 14; and the elastic rubber pad is a circular pad of which the outer diameter is the same as that of the elastic rubber sleeve. The hole plugger has a simple structure and a good plugging effect, is easy and convenient to install and can protect the environment of work sites.
Description
Technical field
The invention belongs to the technical field of mine blasting, relate in particular to a kind of down-hole up-hole plugging device with the big gun hole.
Background technology
In order to obtain demolition effect preferably, in the big gun hole of various explosions, all need block up (filling out) plug behind the filling explosive.The opencut explosion is stopped up the big gun hole and is normally clogged some broken sandstone.Ore deposit, down-hole great majority are some medium-length holes or shallow bore hole; The purpose in filling big gun hole is except that will guaranteeing preferably demolition effect; Can also guarantee that the explosive in the up-hole does not outflow (when particularly using emulsion), the existing method of using is to stop up with stemming, its poor effect and pollution work-yard.
Summary of the invention
The object of the present invention is to provide a kind of simple installation, stop up effective, can protect the down-hole up-hole plugging device of working site environment again.
The objective of the invention is to realize through following technical proposals:
Down-hole of the present invention up-hole plugging device; It is characterized in that forming by the resilient rubbber cushion that the end face that elastic caoutchouc cover and elastic caoutchouc therewith overlap is abutted against mutually; Evenly be provided with one group of inclined platform on one end outer surface of described elastic caoutchouc cover; The other end of described elastic caoutchouc cover is provided with a joint pin, and said resilient rubbber cushion is provided with through hole that is fixedly connected with said joint pin and the gap that is connected with said elastic caoutchouc cover endoporus.
The outer surface of said one group of inclined platform is circular arc and quantity is 10-14.
Described resilient rubbber cushion is and the identical circular pad of described elastic caoutchouc cover external diameter.
Advantage of the present invention:
The present invention is simple in structure, simple installation, stop up effective, can protect the working site environment again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1 of the present invention.
The specific embodimentFigure
Below in conjunction with the description of drawings specific embodiment of the present invention.
Like Fig. 1, shown in 2: down-hole of the present invention up-hole plugging device; It is characterized in that overlapping 3 of the resilient rubbber cushions that 1 end face is abutted against mutually by elastic caoutchouc cover 1 and elastic caoutchouc therewith forms; Evenly be provided with one group of inclined platform 5 on one end outer surface of described elastic caoutchouc cover 1; The other end of described elastic caoutchouc cover is provided with a joint pin 4, and said resilient rubbber cushion 3 is provided with through hole that is fixedly connected with said joint pin 4 and the gap 2 that is connected with said elastic caoutchouc cover endoporus.
The outer surface of said one group of inclined platform 5 is circular arc and quantity is 10-14.
Described resilient rubbber cushion 3 is and the identical circular pad of described elastic caoutchouc cover external diameter.
During use, with a kind of specific purpose tool the end that plugging device has inclined platform is inserted in the blown-out shot hole of prepackage medicine, plugging device relies on the elasticity of one group of inclined platform 5 and rubber tightly to be fixed on the emptying aperture wall.
Then in the big gun hole during powder charge, grug transportation tube and lead fire (quick-fried) rope and resilient rubbber cushion 3 is squeezed open the endoporus of distortion back through elastic caoutchouc cover 1 and get in the big gun hole; After treating that powder charge finishes, grug transportation tube is extracted, and an end of leading fire (quick-fried) rope is stayed in the big gun hole, the other end is connected with outside demolition set through gap 2 backs.Because resilient rubbber cushion 3 has the spring function of rubber, so when grug transportation tube is extracted after, the elastic return of leaning on self material immediately promptly abuts against on the end face of elastic caoutchouc cover 1 to original position, plays the effect of sealing the medicine hole.
