Double-rail trolley convenient for bend turning

Abstract

The invention discloses a double-rail trolley convenient for bend turning. The double-rail trolley comprises a main beam, a conveying outer rail and a conveying inner rail which are connected to the lower end of the main beam, and a double-rail trolley body which is connected to the outer conveying rail and the inner conveying rail in a rolling mode, the double-rail trolley body comprises a bearing beam frame, one end of the bearing beam frame is connected with a fixed bearing beam, one end of the fixed bearing beam is rotationally connected with a first driving wheel system, and the other endof the fixed bearing beam is rotationally connected with a first driven wheel system; and the other end of the bearing beam frame is connected with a movable bearing beam in a sliding mode, one end of the movable bearing beam is rotationally connected with a second driving wheel system, and the other end of the movable bearing beam is rotationally connected with a second driven wheel system. Thedistance between the movable bearing beam and the fixed bearing beam and the rotating angle of the wheel train are adjusted, so that the passing performance requirements of the bending track can be met. The double-rail trolley convenient for bend turning has the advantages that the operation is stable, the structure is simple, additional rail changing mechanisms do not need to be additionally arranged, and the manufacturing cost is low.

Description

【Technical field】 [0001] The invention relates to the technical field of intelligent conveying systems, in particular to a double-track trolley that is convenient for turning on a curve. 【Background technique】 [0002] The double-track trolley is a kind of traction trolley commonly used in intelligent conveying equipment. It is the power device for conveying equipment to travel, and it runs independently on the conveying track by means of friction drive. With the development of the intelligent conveying industry and the diversified requirements of the production workshop, the conveying lines of the double-track trolleys are becoming more and more complex, especially the application of the curved track. The radius and arc length of the inner and outer curved sections of the track are different. The relative position changes in real time, thus putting forward higher requirements for the double-track trolley. [0003] The existing double-track trolley turning technology mainly...

AI Technical Summary

Problems solved by technology

[0003] The existing double-track trolley turning technology mainly adopts two methods: (1) Add a set of track changing mechanism to the existing double-track trolley to complete the rotation action, and use the driving wheel train and driven wheel train to rotate first and then move laterally to realize the double-track The turning of the trolley has the problems of complex process, long turning time, and complicated track changing mechanism; (2) universal wheels are used when turning, and the paths of the front and rear wheels are different, so the design of the track is very complicated , high manufacturing cost
