Double-track trolley variable-structure steering apparatus and system

Abstract

The invention discloses a double-track trolley variable-structure steering apparatus. The double-track trolley variable-structure steering apparatus comprises a traction main trolley, a bearing auxiliary trolley and a rotary variable-structure assembly for connecting the traction main trolley with the bearing auxiliary trolley, wherein the traction main trolley and the bearing auxiliary trolley are installed on a track system, and the track system comprises an inner track and an outer track which are oppositely arranged. The traction main trolley comprises a wheel train assembly installed on the track system, an outer track cross beam and an inner track cross beam. The bearing auxiliary trolley comprises an outer track load beam, an inner track load beam and a load beam. The rotary variable-structure assembly comprises an upper rotation base, a lower rotation base, an upper sliding block and a lower sliding block, wherein the upper rotation base is fixedly connected with the upper sliding block, and the lower sliding bock is fixedly connected with the lower rotation base. The invention further provides a double-track trolley variable-structure steering system. The double-track trolley variable-structure steering apparatus can achieve small-radius turning of a double-track trolley, improves the stability of the double-track trolley during turning operation and meanwhile is simple in structure.

Description

technical field [0001] The invention relates to the technical field of conveyor structures, in particular to a variable-structure steering device for a double-track trolley and a system thereof. Background technique [0002] At present, in terms of the double-track suspension self-propelled conveyor, the overall structure of the double-track suspension self-propelled conveyor is relatively complicated and the manufacturing cost is relatively high. The difficult problem that the double-track trolley needs to overcome when turning is: how to guarantee to pass through the curve smoothly. Due to the different turning radii of the inner and outer tracks and the different speeds of the wheels of the inner and outer tracks, the positional relationship between the front and rear wheel beams of the inner and outer tracks will constantly change. The double-track train bogies commonly used in the prior art are suitable for inter-city double-tracks with a large turning radius, and the ...

AI Technical Summary

Problems solved by technology

The double-track train bogies commonly used in the prior art are suitable for inter-city double-tracks with a large turning radius, and the positional relationship between the front and rear wheel beams of the inner and outer tracks does not change much when turning. Turning can be realized under the action; but for the operation of the factory conveyor is limited by space, the turning radius of the double track is small, and the positional relationship between the front and rear wheel beams of the inner and outer tracks changes greatly during turning, a variable structure design is required

In addition, the four hooks used in some double-track trolleys mostly operate independently, and the positions of each other are controlled by sensors. The structure is complex and the operation is not stable, which is not conducive to the work of the double-track suspension self-conveyor.
