Abstract
The utility model relate to a kind of stemming and pushes and make instrument firm by ramming, comprises U-lag and tamper, and described tamper one end arranges and makes block firm by ramming, make block firm by ramming to mate with U-lag internal diameter, make block firm by ramming to slide in U-lag, described tamper is cylindrical, and U-lag handheld terminal arranges handle.Stemming can push to and require position by the utility model easily; and make firm by ramming with tamper; blocking quality easily reaches designing requirement and reliable initiation; demolition effect is desirable; more safe; and non-fulgurite (or detonator payment to a porter) can be made to be effectively protected, miso-fire generation rate significantly reduces, and decreases the potential safety hazard that process miso-fire exists.
Description
Technical field
The utility model relates to blasting engineering field, and a kind of stemming pushes and makes instrument firm by ramming specifically.
Background technology
The stemming used in blasting engineering is more soft argillo arenaceous hydrate, is mainly used in the blocking in big gun hole.Usually adopt solid tamper push stemming and make firm by ramming at present, this tamper easily makes non-fulgurite (or detonator payment to a porter) discounting in progradation, breakage is even ruptured, and produces miso-fire, and process miso-fire is not only time-consuming but also more dangerous; And this method is only applicable to block shallow big gun hole, block darker on to middle deep blasting hole time, be difficult to stemming is pushed to the position requiring blocking, and then do not reach the stemming length of requirement, when causing explosive charge in big gun hole, aperture resistance reduces, and does not reach desirable demolition effect.
Utility model content
Not enough for above-mentioned prior art, it is easier that the utility model provides one that stemming is pushed, and block effective, safer stemming pushes and makes instrument firm by ramming.
A kind of stemming that the utility model provides pushes and the instrument of making firm by ramming is achieved through the following technical solutions:
A kind of stemming pushes and makes instrument firm by ramming, it is characterized in that: comprise U-lag and tamper, and described tamper one end arranges and makes block firm by ramming, described in make block firm by ramming and mate with U-lag internal diameter, making block firm by ramming can slide in U-lag.
Described tamper is cylindrical.
Described U-lag handheld terminal arranges handle.
The beneficial effects of the utility model are:
1. use U-lag contain stemming and together send into big gun hole; under the protection of U-lag; stemming is easy to just can arrive require position; and make firm by ramming with tamper; aperture resistance when not only increasing explosive charge in big gun hole; and effectively prevent the gases at high pressure formed during explosive charge in big gun hole from releasing from aperture spray, thus reach desirable demolition effect and realize safety blasting.
2. when blocking big gun hole; to the propelling movement of stemming with make firm by ramming in process, non-fulgurite (or detonator payment to a porter) and stemming are isolated by U-lag, thus non-fulgurite (or detonator payment to a porter) is effectively protected; miso-fire generation rate significantly reduces, and decreases the potential safety hazard that process miso-fire exists.
3, use this tool jams big gun hole, blocking quality easily reaches designing requirement and reliable initiation, and demolition effect is desirable, more safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is U-lag, 11 is handle, and 2 is tamper, and 21 for making block firm by ramming.
Detailed description of the invention
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
A kind of stemming pushes and makes instrument firm by ramming, comprises U-lag 1 and tamper 2, and described tamper 2 one end arranges and makes block 21 firm by ramming, described in make block 21 firm by ramming and mate with U-lag 1 internal diameter, making block 21 firm by ramming can slide in U-lag 1.
Further, described tamper 2 is cylindrical.
Further, U-lag 1 handheld terminal joins handle 11, is convenient to operated by personnel.
During use, contain stemming with U-lag 1 and together send into big gun hole, under the protection of U-lag 1, stemming is pushed to and requires position, and hand-held tamper 2 moving up and down along big gun hole, makes firm by ramming stemming.
The above embodiment only represents embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to the utility model protection domain.
Claims (3)
1. stemming pushes and makes an instrument firm by ramming, it is characterized in that: comprise U-lag and tamper, and described tamper one end arranges and makes block firm by ramming, described in make block firm by ramming and mate with U-lag internal diameter, making block firm by ramming can slide in U-lag.
2. a kind of stemming according to claim 1 pushes and makes instrument firm by ramming, it is characterized in that: described tamper is cylindrical.
3. a kind of stemming according to claim 1 pushes and makes instrument firm by ramming, it is characterized in that: described U-lag handheld terminal arranges handle.
