Background technology

Stemming is to be used for the material of plugged perforation; The quality of stemming and be shaped quality, sealing clay length and sealing quality etc. directly influence demolition effect and safety.

Stemming mainly is the demolition effect that can improve explosive, increases a resistance of mouth, makes and builds up the compression ability in the borehole; Improve the impulsive force of shock wave; Stop the detonation gas of high pressure to release certain applications, can also make explosive fully oxidation in explosive reaction simultaneously, emit more energy from the borehole spray; Make heat fully be converted into mechanical energy, thereby reach desirable demolition effect.Simultaneously, guarantee shotfiring safety, the temperature and pressure when reducing detonation gas effusion working face; Also because stemming can stop flame and scorching hot solid particle in borehole, to spray, reduced the possibility of the gas that ignites, coal dust simultaneously.

Stemming need be processed strip before putting into borehole, in the prior art, mainly is to pinch shaping through artificial hand.Hand is pinched shaping not only increases operator's labour intensity, reduces operating efficiency, and the stemming after being shaped is different, and size criteria is different, encapsulates unreally, in the process of blowing out, is prone to naked light, has very big potential safety hazard.For overcoming the above problems, Stemming machine has appearred, have high efficiency, result of use is better.But common Stemming machine has bigger volume and weight, needs bigger drive energy, uses and keeps in repair very inconvenience, and operating cost is higher.

Therefore, need improve, alleviate operator's labour intensity, increase work efficiency, make the unified size that has standard after the stemming moulding simultaneously, have effect preferably, have smaller volume and weight existing stemming moulding means, easy to use.

The utility model content

In view of this, the purpose of the utility model provides a kind of pneumatic stemming shaped device, during use; Alleviate operator's labour intensity, increase work efficiency, make the unified size that has standard after the stemming moulding simultaneously; Have effect preferably, have smaller volume and weight, easy to use.

The pneumatic stemming shaped device of the utility model, comprise Pneumatic assembly, body and with the interior piston that is slidingly matched with it in the body that is placed in, the gas outlet of said Pneumatic assembly is communicated in body and is positioned at the actuator chamber that piston tail forms; Said piston is provided with and is used to make its return spring of return backward.

Further, said body tail end sealing, the piston rod tail end sealing of piston passes the tail end of body and is provided with positive stop lug boss, and said return spring is coated at piston rod two ends correspondence and withstands body tail end and positive stop lug boss;

Further, Pneumatic assembly comprises the driving tracheae that is used to connect high-pressure air source, and said driving tracheae is communicated in actuator chamber;

Further, Pneumatic assembly also comprises triple valve, and said triple valve is provided with air inlet, exhaust outlet and porting, and said porting is communicated in actuator chamber, and air inlet is communicated in the gas outlet that drives tracheae;

Further, it is forming cavity that said body is positioned at the anterior cavity of piston, and said forming cavity is positioned at tube body wall and has bar shaped steam vent longitudinally, and the longitudinal length of said bar shaped steam vent is less than the longitudinal length of piston;

Further, tube body wall outer round surface front end closes up to the center and forms circular cutting edge;

Further, said body afterbody is provided with and controls handle.

The beneficial effect of the utility model is: the pneumatic stemming shaped device of the utility model, adopt the piston type building mortion, and utilize the plasticity of stemming itself; With the body is the mould direct forming, and is used by pneumatic the release through piston, alleviates operator's labour intensity; Be shaped rapidly, increase work efficiency, make the unified size that has standard after the stemming moulding simultaneously; Have effect preferably, and the utility model is simple in structure, volume is little, and the shaping operation method is simple; Easy to use flexible, practice thrift cost.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the triple valve structure principle chart.

The specific embodiment

Fig. 1 is the structural representation of the utility model; Fig. 2 is the triple valve structure principle chart; As shown in the figure: the pneumatic stemming shaped device of present embodiment; Comprise Pneumatic assembly, body 1 and with the interior piston 2 that is slidingly matched with it in the body 1 that is placed in, the gas outlet of said Pneumatic assembly is communicated in the actuator chamber 1a that body 1 is positioned at the formation of piston 2 afterbodys; Said piston 2 is provided with and is used to make its return spring 6 of return backward.

In the present embodiment, said body 1 tail end sealing, the piston rod 2a tail end sealing of piston 2 passes the tail end of body 1 and is provided with positive stop lug boss 2b, and sealing means can adopt multiple structure, such as sealing gasket, O RunddichtringO etc.; Said return spring 6 is coated at piston rod 2a two ends correspondence and withstands body 1 tail end and positive stop lug boss 2b; Adopt the external spring structure, avoid motion artifacts, prevent bite.

In the present embodiment, Pneumatic assembly comprises the driving tracheae 5 that is used to connect high-pressure air source, and said driving tracheae 5 is communicated in actuator chamber 1a;
