Low-temperature start assisting device of mining explosion-proof diesel engine

Abstract

The invention belongs to the technical field of underground coal mine explosion-proof diesel engines, and provides a low-temperature start assisting device of a mining explosion-proof diesel engine. The low-temperature start assisting device comprises a heating rod, a base, an explosion-proof shell and a horn mouth. One end of the heating rod is arranged in a combustion chamber of the explosion-proof diesel engine. The middle of the heating rod is arranged in the base and is fixed to the base through high temperature resisting heat insulation glue arranged between the heating rod and the basein a filling manner. A threaded explosion-proof face is arranged on the outer circle of one end of the base. One end of the explosion-proof shell is fixedly arranged on the base through the threaded explosion-proof face and surrounds the other end of the heating rod. The space between the explosion-proof shell and the heating rod is filled with epoxy resin. A positive lug plate and a negative lugplate are arranged on the heating rod. An explosion-proof is connected with the positive lug plate and the negative lug plate after entering the explosion-proof shell from the horn mouth. According tothe low-temperature start assisting device, normal start of an explosion-proof vehicle under the low temperature work condition can be guaranteed, safety and reliability are achieved, and the low-temperature start assisting device can be widely applied to the field of coal mines.

Description

technical field [0001] The invention belongs to the technical field of underground explosion-proof diesel engines in coal mines, and in particular relates to a low-temperature auxiliary starting device for explosion-proof diesel engines used in mines. Background technique [0002] Most of the coal mines in our country are mostly distributed in mountainous areas. The lowest temperature in mountainous areas is far below -10°C in winter. Trackless rubber-tyred vehicles powered by explosion-proof diesel engines will have difficulty starting at -5°C. Vortex type explosion-proof diesel engines are particularly prominent. Need Artificially using auxiliary equipment to heat the explosion-proof diesel engine or injecting low-temperature starting fluid into the intake pipe to start the vehicle affects the efficiency of the coal mine explosion-proof diesel engine vehicle in winter. In order to solve the problem of difficult starting at low temperature, the ground vehicle is equipped wi...
