Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] The purpose of the present invention is to provide a manual mechanical safety starting device for explosion-proof vehicles in coal mines, so as to solve the problems in the prior art mentioned above, realize the neutral gear start without stepping on the clutch by the driver, and reduce the wear and tear of the clutch. The vehicle slipping caused by starting with a gear is avoided, and the safe handling performance of the vehicle is improved.

Abstract

The invention discloses a manual mechanical safety starting device for an underground coal mine explosion-proof vehicle. The device comprises a starting air tank, a stop valve, a drainage switch, a vehicle-mounted air compressor, a one-way valve, a safety valve, a main switch valve, an unloading valve, a first filter, a second filter, a main starting valve, a starting motor, a starting valve, a pneumatic switch valve, a barometer, a first pneumatic control reversing valve, a first hydraulic control reversing valve, a first shuttle valve, an electromagnetic valve, a second shuttle valve, a reverse gear locking valve, a forward locking valve, an air door air cylinder, a second hydraulic control reversing valve, a pressure regulating valve, an engine oil pressure gauge, an engine oil pump, anoil pan, an installation plate, a bolt, a gearbox gear shifting arm and a special-shaped plate which are connected through respective pipelines and connectors. According to the device, neutral gear starting is achieved under the condition that a driver does not step on a clutch, abrasion of the clutch is reduced, vehicle sliding caused by starting with a gear is avoided, and the safety control performance of a vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of safe starting of explosion-proof vehicles in coal mines, in particular to a manual mechanical safety starting device for explosion-proof vehicles in coal mines. Background technique [0002] There are a large number of explosion-proof rubber-tyred vehicles with mechanical transmission in underground coal mines, and the transmission route is explosion-proof diesel engine-explosion-proof clutch-gearbox-drive axle. Due to the need to solve the explosion-proof problem of the electric control system for underground vehicles in coal mines, and after the explosion-proof, the volume is huge, the layout is difficult, and the cost is increased, which reduces the cost competitiveness of the whole vehicle. In this case, it is particularly important to invent a kind of safety starting device for the neutral gear of the explosion-proof vehicle with manual mechanical gear shifting under the coal mine. The mechanically ...
