Carbon dioxide blasting equipment

Technical Field

The utility model belongs to the technical field of carbon dioxide blasting, and particularly relates to carbon dioxide blasting equipment.

Background

Carbon dioxide blasting is mainly developed for coal mining working faces of high gas mines aiming at avoiding explosion accidents caused by flame generated by explosive blasting, carbon dioxide gas can be converted into liquid under certain high pressure, liquid carbon dioxide is compressed into a cylindrical container by a high-pressure pump, a safety film, a rupture disc, a heat conducting rod and a sealing ring are arranged in the cylindrical container, the preparation work before blasting is finished by screwing an alloy cap, when micro-current passes through the heat conducting rod, high temperature is generated to puncture the safety film, solid carbon dioxide is instantly gasified, rapid expansion generates high-pressure shock wave to cause the relief valve to automatically open, the volume rapid expansion generates high pressure to cause rock cracking when solid carbon dioxide absorbs heat and is gasified, but the prior carbon dioxide blasting device is inconvenient to fix when in use, if the preformed hole is in an inclined state, the blasting tube can slide downwards, and blasting work cannot be smoothly carried out.

Therefore, it is very critical to develop a carbon dioxide explosion equipment capable of solving the above problems.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: the device comprises a main pipe 1, an energy discharging port 11, an energy discharging head 12, an energy discharging sheet 13, a heating pipe 14, an initiation head 15, a sleeve 2, a second transmission rod 21, a support bar 22, a first transmission rod 23, a transmission ring 24, a pushing bolt 25, a fixing ring 26 and an anti-skid protrusion 27.

Detailed Description

The utility model is further described with reference to the accompanying drawings, but the utility model is not limited in any way, and any alterations or substitutions based on the teaching of the utility model are within the scope of the utility model.

As shown in the attached drawing 1, the utility model includes a main pipe 1, a sleeve 2 is arranged on the periphery of the main pipe 1, the main pipe 1 and the sleeve 2 are fixedly connected, a transmission ring 24 capable of moving on the sleeve 2 is arranged on the periphery of the sleeve 2, three first transmission rods 23 are rotatably connected to the transmission ring 24, the first transmission rods 23 are rotatably connected to the end points of support strips 22, the other ends of the support strips 22 are rotatably connected to the end points of second transmission rods 21, the other ends of the second transmission rods 21 are rotatably connected to the sleeve 2, pushing bolts 25 are fixedly connected to the transmission ring 24, an energy discharging head 12 is screwed to the front end of the main pipe 1, an energy discharging piece 13 is arranged between the main pipe 1 and the energy discharging head 12, an energy discharging port 11 is arranged on the energy discharging head 12, an initiation head 15 is screwed to the tail end of the main pipe 1, and a heating pipe 14 is arranged between the main pipe 1 and the initiation head 15.

The three first driving levers 23 are evenly distributed on the driving ring 24.
