Electric-traction rack rail railcar

Abstract

The invention relates to an electric-traction rack rail railcar. By successfully developing the electric-traction rack rail railcar, the contradiction between the rapid development of coal mining, shoring and heading equipment and underdeveloped underground coal mine subsidiary transportation equipment in China is alleviated, and the updating and upgrading of coal mine equipment in China are maximally promoted. The electric-traction rack rail railcar comprises rails and standers, wherein a cab, an anti-explosion diesel generator, an anti-explosion variable frequency motor, a three-stage gear reducer, an electric control tank, and a guiding and anti-rollover steering frame are arranged on the standers. The electric-traction rack rail railcar has the beneficial effects that the whole vehicle is electrically and mechanically driven and is powered by the vehicle-mounted anti-explosion diesel generator, and a low-speed large-torque driving manner can be realized by virtue of the anti-explosion variable frequency motor and the three-stage gear reducer; by utilizing the anti-explosion variable frequency motor, the emergency braking, the driving braking, parking braking and the like of the railcar are realized by virtue of the coordinate operation of a variable-frequency governor and a braking system; the guiding and anti-rollover steering frame with a guiding wheel can play guiding and anti-rollover roles; the electric-traction rack rail railcar is environment-friendly, safe and efficient and has an automatic function.

Description

technical field [0001] The invention relates to the technical fields of machinery, electronics, and hydraulic pressure, and in particular relates to an electric traction rack rail car. Background technique [0002] In recent years, due to the slow development of domestic coal mine auxiliary transportation equipment technology, most of the advanced domestic transportation equipment relies on imports. The cog rail truck transportation system is an ideal equipment for safe transportation in high-gas, high-inclination coal mines. It can realize the auxiliary transportation automation of coal mine and tunnel engineering, and eliminate the hidden danger of accidents to the greatest extent. [0003] Germany, Poland, Russia and other countries have successively developed rack rail trucks, special equipment for underground auxiliary transportation, powered by high-power, explosion-proof diesel engines and driven by hydraulic-mechanical drives. Its main feature is that it can perfor...

Problems solved by technology

However, according to the user’s feedback, in the process of use, the cog rails are laid throughout the entire process, and the transportation system has defects such as low efficiency (about 60%) and difficult maintenance of the hydraulic system.

[0004] At present, most of the trucks used in coal mines in my country rely on imports, which are costly and difficult to maintain

It is understood that several research and development institutions in China have been developing rack cars recently, but the main transmission of the locomotives continues the foreign technology and adopts hydraulic-mechanical drive, and has been partially produced in small batches, but they all have small traction and insufficient climbing ability. The disadvantages of low transportation efficiency are as follows: 1) The existing products are mainly based on hydraulic-mechanical transmission, which has low efficiency, generally 50-60%, and difficult system maintenance; 2) The track rack is laid throughout the whole process , low transportation efficiency; 3) Domestic products have low traction and insufficient climbing ability; 4) The locomotive speed control adopts hydraulic speed control, which has slow response speed and is not flexible
