Description

Technical Field

[0001] This application relates to the technical field of gas blasting, and particularly to an air energy gas blasting device. Background Technique

[0002] Gas blasting technology is a method of using gas pressure to generate high-pressure gas shock waves to break rocks. During specific operations, the rocks to be blasted are pre-treated first. Drilling is carried out according to requirements, a blasting device is placed in the drill hole, and detonation is carried out. When the shock wave impacts the rock, the cracks and damaged surfaces in the rock are violently impacted by the high-pressure gas. Therefore, a huge force is generated inside, forming cracks and fracture surfaces, thereby achieving the purpose of blasting.

[0003] Traditional gas blasting devices produce loud noises and strong vibrations during the blasting process, causing greater impacts on the surrounding environment and facilities. Moreover, the operation is complex, with high technical requirements for operators, and there are certain potential safety hazards.

[0004] Regarding the above related technologies, traditional gas blasting devices are highly dangerous during the blasting process, cause greater impacts on the surrounding environment and facilities, and there are also potential safety hazards during storage and transportation.

[0056] The following further elaborates on this application with reference to the Figure 1-2 accompanying drawings.

[0057] The embodiment of this application discloses an air energy gas blasting device.

[0058] Referring to Figure 1 , the air energy gas blasting device includes a blasting component 1, a gas guiding component 2, and a plugging component 3. The blasting component 1 is used for blasting at a specified location. The gas guiding component 2 is connected to the blasting component 1 and is used to introduce liquid oxygen into the blasting component 1. The plugging component 3 is installed on the blasting component 1 and is used to plug the blasting component 1 in the blasting hole.

[0059] When the air energy gas blasting device is in use, after determining the blasting target and scope, a hole is drilled at the position to be blasted, the blasting component 1 is placed into the hole, the gas guiding component 2 is connected, the plugging component 3 is opened, and the blasting component 1 is plugged in the blasting hole to prevent the blasting component 1 from flying out of the hole instantly during blasting, which may affect the blasting effect. Liquid oxygen is filled into the blasting component 1 through the gas guiding component 2 for blasting.

[0060] Referring to Figure 1 and Figure 2 , the blasting component 1 includes a filling tube 11, a cracking tube 12, a filler 13, a film, and an electric igniter 15. The cracking tube 12 is fixedly installed in the filling tube 11. The material of the cracking tube 12 is high-strength alloy steel. The filler 13 is filled in the cracking tube 12. The film tightly wraps the filler 13. The filler 13 is special loose roll paper. The electric igniter 15 is fixedly installed in the cracking tube 12.

[0061] The gas guiding component 2 includes an inflation head 21, a filling pipe 22, a liquid oxygen tank 23, a filling machine 24, an intake pipe 25, and an exhaust pipe 26. The inflation head 21 is cooperatively connected with the cracking tube 12. The filling pipe 22 is communicated with the inflation head 21. The liquid oxygen tank 23 is communicated with the filling pipe 22. The filling machine 24 is connected to the filling pipe 22. The intake pipe 25 is fixedly installed in the cracking tube 12. The material of the intake pipe 25 is aluminum. The exhaust pipe 26 is fixedly installed in the cracking tube 12. The material of the exhaust pipe 26 is rubber.

[0062] When the air - energy gas blasting device is in use, liquid oxygen passes through the filling pipe 22 from the liquid oxygen tank 23, and then is transported into the splitting pipe 12 through the filling head. The liquid oxygen is poured into the special loose roll paper, and the liquid oxygen filling amount is controlled by the filling machine 24. The film heat insulation makes it impossible for the liquid oxygen to absorb a large amount of heat from the external environment to instantaneously vaporize. When instantaneously excited by the heat source of the electric igniter 15, the unstable liquid oxygen in the gaps of the roll paper quickly vaporizes, and its volume expands by 860 times. This expansion force acts on the plug hole wall. When it is greater than the tensile and shear strength of the rock, the rock around the plug hole cracks.

[0063] The air inlet pipe 25 is an aluminum pipe, and the structure of the aluminum pipe itself can ensure that it can be quickly restored to a normal use state after expansion. The exhaust pipe 26 is a rubber pipe, and the rubber pipe can ensure that there is enough variable space for the expanding air during the exhaust process.

[0064] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the plugging assembly 3 includes a sleeve 31, a fixing block 32, a screw 33, a moving block 34, no less than one clamping insert tooth 35, a connecting rod 36 and a side hole 37. The sleeve 31 is a cylindrical tubular structure. The sleeve 31 is thread - connected to the top end of the filling pipe 11. The fixing block 32 is fixedly installed on the sleeve 31. The screw 33 is rotatably installed on the sleeve 31. The screw 33 passes through the fixing block 32. The moving block 34 is thread - connected to the screw 33. One end of no less than one clamping insert tooth 35 is hinged to the fixing block 32. One end of the connecting rod 36 is hinged to the moving block 34. The end of the connecting rod 36 far from the moving block 34 is hinged to the clamping insert tooth 35. The side hole 37 is opened on the sleeve 31, and the side hole 37 corresponds to the clamping insert tooth 35 one by one. A handwheel 4 is fixedly installed at the end of the screw 33 far from the sleeve 31.

[0065] When the air - energy gas blasting device is in use, turn the handwheel 4, which drives the screw 33 to rotate. Under the action of the screw 33, the moving block 34 moves upward, driving the clamping insert teeth 35 and the connecting rod 36 to diverge outward. The clamping insert teeth 35 pass through the side holes 37 and are inserted into the side wall of the blasting hole to plug the hole, preventing the blasting assembly 1 from rushing out of the hole under the impact of the blasting force during the blasting instant, thus affecting the blasting operation. After the blasting is completed, reverse the handwheel 4, the clamping insert teeth 35 and the connecting rod 36 contract, and the blasting device is taken out to complete the blasting operation.

[0066] The implementation principle of an air energy gas blasting device in an embodiment of the present application is as follows: When the air energy gas blasting device is in use, after first determining the blasting target and scope, holes are drilled at the position to be blasted, the blasting filling pipe 11 is placed into the hole, liquid oxygen is filled into the filler 13 in the bursting pipe through the filling pipe 22, and then by rotating the handwheel 4, the clamping insert teeth 35 pass through the side hole 37 and are inserted into the side wall of the blasting hole to seal the hole opening. The electric igniter 15 is activated, and instantly excited by the heat source of the igniter, the unstable liquid oxygen in the filler 13, that is, in the gaps of the special loose tissue paper, rapidly vaporizes, with the volume expanding by 860 times. When the expansion force acts on the hole wall and is greater than the tensile and shear strength of the rock, the rock around the hole cracks, achieving the purpose of blasting.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
