Problems solved by technology

[0003] Since the shuttle car is in 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

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing:

[0029] As shown in Fig. 1, it is the overall structure diagram of walking and steering. The traveling mechanism is that the rear wheels drive the front wheels. The front part of the wheel 11 connects the long drive shaft 7 and the front wheel 9 to form a travel motor 13 to drive the rear wheel 11 and the front wheel 9 to move forward, retreat, and turn; Device 16, walking reducer 16 connects walking motor 14, and walking rear wheel 12 fronts connects long transmission shaft 8, walking front wheel 10, forms walking motor 14 driving walking rear wheel 12, walking front wheel 10 advances, retreats, turns to.

[0030] The steering mechanism is completed by the connecting rod bogie 1. The synchronous shaft 2 of the bogie 1 is the central axis of steering. The steering block 22 is connected with the longitudinal tie rod 6, the steering cylinder 24, the upper steering arm 30, the...

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-tyred shuttle car, 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. Among the follow-up equipment of continuous mining machines, shuttle cars are the most important equipment. The mined coal is loaded into the material box and run to the receiving end of the feed crusher. The walking, turning, feeding and unloading of the shuttle car have become very important technologies. [0003] Since the shuttle car is in 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 loa...
