Carbon dioxide blasting device device thruster The utility model discloses a thruster, in particular a carbon dioxide blasting device thruster. Liquid carbon dioxide phase change pre-cracking technology uses liquid carbon dioxide to convert from liquid state to gaseous state and expands in the process of heating. Its expanding gas generates high pressure in a specific volume of the container and is ejected through a specially designed injection hole to achieve pre-preparation. The purpose of cracking or destroying rocks and seams. Technical equipment has intrinsic safety features, in which both liquid carbon dioxide and gaseous carbon dioxide are inert, non-flammable and explosive substances. The starting voltage of the heater is 9 volts. At present, the newly designed heater starter will fully meet the safety requirements of underground coal mines. In addition to the direct equipment and transport equipment, carbon dioxide blasting equipment installations include auxiliary equipment such as liquid carbon dioxide bottles, filling racks, filling equipment, and conduction testers before start-up. However, when the carbon dioxide blasting device device is in use, it needs to be fixed in the coal seam. The common practice in the prior art is to use a drilling device to drill a hole in the coal layer and then blow the carbon dioxide to blast the liquid carbon dioxide in the equipment device. Insert into the hole to achieve. In the conventional practice, the tubular member is usually inserted directly into the drilled hole. However, it cannot guarantee the depth of insertion (holding of more than twenty meters and the self-weight of several hundred kilograms) and stability after insertion. The use of inconvenience. For the above-mentioned prior art carbon dioxide blasting device device in use can not guarantee the depth of the insertion of the tubular member and the stability after the insertion and other shortcomings, the utility model provides a new carbon dioxide blasting device device thruster, the thruster The use of an oil cylinder as a propulsion mechanism can effectively ensure the stability of the tubular components in the carbon dioxide blasting device installation in the coal seam. The technical solution adopted by the utility model to solve the technical problems is: a propelling device for a carbon dioxide blasting device, the propeller includes an abutment and an oil cylinder, the cylinder is fixedly installed on the top of the abutment, and a piston rod for pushing the drill rod is arranged in the oil cylinder. . The technical solution adopted by the utility model to solve the technical problems further includes: The drill pipe is fixedly placed on the top of the oil cylinder. The drill pipe is provided with a guide block inside the warehouse. An end cap is fixedly installed at the top of the drill rod into the bin, and a stop block is installed inside the end cap. A spring cover is installed on the end cover, and a spring is arranged between the spring cover and the blocking block. The base of the said support is a chassis, a cylinder supporting rod is fixedly installed on the chassis, and the cylinder is fixedly installed on the supporting rod of the cylinder. The propeller also includes a pumping tool, which supplies the hydraulic oil to the support and the cylinder through the pipeline. The utility model has the beneficial effects that the utility model adopts a support and a cylinder structure, so that the high-pressure tube in the carbon dioxide blasting device can be easily and conveniently entered into the hole along with the drill rod, and the inserting depth and the inserting can be ensured. stability.
