Lifting straddle type monorail turnout

Abstract

The invention discloses a lifting straddle type monorail turnout. The lifting straddle type monorail turnout comprises a first turnout lifting beam (4) and a second turnout lifting beam (5), wherein the first turnout lifting beam (4) is used for being connected with a first turnout fixing beam (1) and a third turnout fixing beam (3), and the second turnout lifting beam (5) is used for being connected with a second turnout fixing beam (2) and the third turnout fixing beam (3); the first turnout lifting beam (4)and the second turnout lifting beam (5) are both connected with a driver, and the first turnout lifting beam (4) and the second turnout lifting beam (5) are used for being driven by the driver to ascend and descend; guide columns among the beams are arranged on both the first turnoutlifting beam (4) and the second turnout lifting beam (5). According to the lifting straddle type monorail turnout, structuresand a specific arrangement mode of key components of the lifting straddle type monorail turnout, a beam replacement way corresponding to the overall turnout beams and the like are improved, and compared with the prior art, the lifting straddle type monorail turnout can be used for effectively solving the problem that the turnout beamsoccupya large horizontal space.

Description

technical field [0001] The invention belongs to the technical field of straddle type single track switch, and more specifically relates to a lifting type straddle type single track switch, which is a new type of straddle type single track switch. Background technique [0002] Unlike traditional railways, monorails have only one running track, and are mainly aimed at densely populated places to carry passengers. A straddle monorail is a more commonly used type of monorail. Monorail turnout, that is, the turnout used on monorail railways, is a line connection device that enables vehicles to transfer from one monorail strand to another. Single track turnout is an extremely important part of monorail railway, and it is also one of the weak links. [0003] The existing straddle-type single-track switch realizes the connection and conversion of the line through translational motion, and the translational forms of the straddle-type single-track switch can be summarized into two t...

AI Technical Summary

Problems solved by technology

During the operation of the single-track turnout in the form of general translation, it has high requirements for control accuracy and the operating position of the turnout beam, and is easily affected by the environment. The system is complex, the operating speed is slow, and the reliability is not high.

And because the existing turnout needs to meet the limit, it will cause the overall turnout to be longer

[0004] Chinese patent document CN 103276643A discloses a monorail tram track using a lifting parallel turnout. Although this new type of turnout can effectively use the vertical space and reduce the horizontal footprint, the lifting parallel turnout still has technical difficulties that need to be overcome urgently , making it impractical for the time being

Especially the guide and limit problems when the turnout lifting beam rises, and the vehicle load bearing problem. For the turnout lifting beam, due to the limitation of the beam replacement form, the turnout beam is prone to insufficient movement when lifting and lowering, and the positioning accuracy of the turnout beam is affected by the environment. Factors, control accuracy, sensors or travel switches; the existing single-track bifurcated girder connection devices generally have complex structures, slow running speeds, and low reliability

As for the load bearing capacity of the vehicle, the translational turnout beam is supported by the bottom foundation, and it is not necessary to focus on the pressure of the vehicle crossing on the turnout, and it is not necessary to additionally consider the vehicle load bearing mechanism; but in the lifting type single track switch , the direction of movement of the turnout beam (the direction of the driving force of the motor) is consistent with the direction of the vehicle load, and the motor is not suitable for providing bearing capacity
