Electric traction rack truck

Abstract

The invention relates to an electric traction rack rail car. The successful development of the car alleviates the contradiction between the rapid development of coal mining, support and excavation equipment in my country and the backward auxiliary transportation equipment in coal mines. It has promoted the upgrading of my country's coal mine equipment to the greatest extent. The present invention includes a track and a frame. The frame is equipped with a cockpit, an explosion-proof diesel generator, an explosion-proof variable-frequency motor, a three-stage gear reducer, an electric control box, a guiding anti-rollover steering frame, etc. The whole locomotive adopts electric-mechanical transmission. , driven by a vehicle-mounted explosion-proof diesel generator, through an explosion-proof variable-frequency motor and three-stage gear reduction, it can realize low-speed high-torque drive; it uses an explosion-proof variable-frequency motor, and through the coordinated use of variable-frequency speed regulation and braking systems, it can realize emergency braking and braking of locomotives. Driving brake, parking brake, etc.; the guiding and anti-rollover steering frame with guide wheels can play the role of guiding and anti-rollover; the electric traction rack rail car of the present invention is a green, safe, efficient, and automatic function A new type of mining transport vehicle integrated.

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
