Walking steering apparatus for rubber wheel shuttle car

Abstract

The present invention relates to the traveling and steering mechanism of shuttle car with rubber wheels. The traveling and steering mechanism has structure comprising a steering rack, wheels, a traveling motor, a traveling speed reducer, a wheel side speed reducer, a sync shaft, a long transmission shaft, a short transmission shaft, a transverse pull rod, a longitudinal pull rod, a steering oil cylinder, a steering block, and steering head, an upper steering arm and a lower steering arm. It has the traveling mechanism designed through combining the traveling motor, the traveling speed reducer and other parts, and the steering mechanism of link rod type. It has small turning radius, can in-site turning and is suitable for shuttling operation in the narrow underground room. It possesses the advantages of integral linkage, compact structure, convenient operation, etc.

Description

technical field [0001] The invention relates to a walking steering device of a rubber-wheeled shuttle, which belongs to the technical field of auxiliary transportation equipment parts in coal mines. Background technique [0002] In modern large and medium-sized coal mines, continuous mining machines have been introduced and used in long-wall and short-wall mining. In the follow-up equipment of continuous mining machines, shuttle cars are the most important equipment. The mined coal is loaded into its material box and run to the receiving end of the feeding crusher. The shuttle car's walking, turning and feeding, and unloading have become very important technologies. [0003] Since the shuttle car is the follow-up operation of the continuous excavator, and it is in a narrow roadway, the running space is small and the turning radius is small, the walking and steering of the shuttle car are greatly restricted, and the shuttle car itself The self-weight is 26T, and the loading ...

AI Technical Summary

Problems solved by technology

[0003] Since the shuttle car is the follow-up operation of the continuous excavator, and it is in a narrow roadway, the running space is small and the turning radius is small, the walking and turning of the shuttle car are greatly restricted, and the shuttle car itself The self-weight is 26T, and the loading capacity can reach 14-20T, which has caused great difficulties for the normal transportation of the shuttle car. In order to make the shuttle car work normally in the narrow roadway, many measures have been taken, but none of them are satisfactory. Ideal, some use to expand the roadway area, but the cost is high and it is not safe; some use to reduce the load, the efficiency is low; Existing technology has many disadvantages
