Flexible turnout and its flexure device for straddling monorail

Abstract

The invention discloses a flexible turnout for straddle-type monorail transit and a flexure device thereof. The flexure device comprises a power assembly and a plurality of driven assemblies. Each driven assembly comprises a gear shaft extending in the vertical direction, a driving wheel, two gears, two racks and connecting plates, the driving wheels are arranged at the lower end of the gear shafts to drive the gear shafts to rotate, the two gears are fixed on the g gear shafts at intervals in the up-and-down direction and located above the driving wheels, every two gears separately mesh withevery two racks in a one-to-one correspondence fit mode to drive the corresponding racks to move horizontally, the two ends in the moving direction of each rack are separately provided with the connecting plates, each of the connecting plates can rotate relative to the corresponding rack, and the power assembly is separately matched with the driving wheels of the driven assemblies to drive the main wheels to rotate. According to the flexure device, bending of the flexible turnout can be smoothly realized, the wear of the flexure device in the bending process of the flexible turnout is reduced,and the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a flexible turnout for straddling monorail transportation and a bending device thereof. Background technique [0002] Most of the flexure devices used in the flexible turnouts used in straddle-type monorails in the related art adopt the driving form of the series connection of cam pull rods to realize the synchronous bending of the guide panel and the stability panel. At both ends of the fork pull rod, the double fork pull rod is connected with the driven assembly, and the driven assembly is connected with the cylindrical cam mechanism, and the upper two adjacent cylindrical cam mechanisms and the upper and lower corresponding two cylindrical cams are connected through connecting rods , when the electric push rod starts to push and pull, the pull rod drives the guide panel to realize horizontal synchronous movement, thereby completing the lateral bending of the guide ...

AI Technical Summary

Problems solved by technology

[0003] The deflection device of the related art has the following problems: 1) The serial connection system of the cam pull rod has a complex structure and a large overall size, which cannot meet the requirements of compact structure. The system has strict requirements on the length of each pull rod and connecting rod, and the processing accuracy and assembly The accuracy requirements are too high; 2) The cylindrical cam is used to connect the rollers, and the wear amount of the rollers is large in the later stage, and the wear amount cannot be compensated, which will cause serious impact and deflection deformation. The worn rollers can only Replacement, use and maintenance costs are high; 3) Cylindrical cams require high machining accuracy and manufacturing costs, are inconvenient to lubricate, and are difficult to maintain. Moreover, cylindrical cams of various specifications need to be configured in the same group of turnouts, which increases the overall cost of turnouts
