Description

Technical Field

[0001] The present invention relates to a traction rescue device for a maglev train, belonging to the technical field of traction rescue for rail transit vehicles. Background Art

[0002] As a form of rail transit, the maglev train is currently in the stage of technical exploration and research compared with the existing wheel-rail intercity EMU system technology. During the operation of the maglev train, it is necessary to consider transferring the faulty vehicle from the track to the nearest station when the train breaks down and loses power.

[0003] In traditional rail transit vehicles, a traction seat is installed at the front end of the vehicle to facilitate the connection of rescue vehicles. In the field of maglev trains, due to its structure and material strength, the mounting seat cannot be installed at the front end of the vehicle. Therefore, it is necessary to set up a traction rescue device that can quickly connect the traction vehicle without affecting the appearance of the vehicle cowl. Summary of the Invention

[0013] Preferably, the traction cross beam further includes:

[0014] A side vertical plate fixedly connected between the middle arc extension parts of the cross beam bottom plate and the cover plate, and a cross beam flange plate for connecting with the traction longitudinal beam is fixedly connected at its end, and connecting holes are arranged on the cross beam flange plate.

[0015] Preferably, the traction longitudinal beam includes:

[0016] A box-shaped structure fixedly connected by a longitudinal beam vertical plate, a longitudinal beam cover plate and a longitudinal beam bottom plate; a longitudinal beam flange plate is fixedly connected at one end of the traction longitudinal beam connected with the traction cross beam, and connecting holes corresponding to the cross beam flange plate are arranged on the longitudinal beam flange plate; a sealing plate is fixedly connected at the other end of the traction longitudinal beam.

Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0031] It should be noted that the structures, proportions, sizes, etc. shown in the attached drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions that can be implemented in this application. Therefore, they do not have substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects that this application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in this application.

[0032] Please refer to Figures 1 to 5 . In a specific embodiment of the present invention, a maglev train traction rescue device 2 is provided, which is installed below the maglev train car body 1 and includes a traction cross beam 21, a traction longitudinal beam 22, and a U-shaped bracket 23; the traction cross beam 21 is detachably and fixedly connected to the side beam of the car body 1; the traction longitudinal beam 22 is supported below the floor of the car body 1 through the U-shaped bracket 23, and the U-shaped bracket 23 is detachably and fixedly connected to the floor of the car body 1; one end of the traction longitudinal beam 22 is detachably and fixedly connected to the traction cross beam 21, and the other end is provided with a fixed pin hole for connecting with a traction rod.

[0033] The T-shaped structure maglev train traction rescue device 2 composed of the traction cross beam 21 and the traction longitudinal beam 22 effectively solves the problem of limited installation positions of the maglev train car body 1. And the detachable and fixed connection of the traction cross beam 21 and the side beam of the car body 1, as well as the setting of the U-shaped bracket 23 to support the longer cantilever structure of the traction longitudinal beam 22, effectively improves the stability of the maglev train traction rescue device 2 and reduces the impact on the car body during the traction process.

[0034] Furthermore, as Figure 2 shown, in this embodiment, the traction cross beam 21 is formed by welding the following plates:

[0035] The transverse rib plate 211, the connecting bottom plate 212, the cross beam bottom plate 213, the cross beam flange plate 214, the cross beam cover plate 215, the side vertical plate 216, and the cross beam vertical plate 217. All plates are integrally cut and formed, and the bent parts of some plates are integrally formed by bending, effectively reducing the number of weld joints and avoiding stress concentration problems, and improving the structural strength of the traction cross beam 21.

[0036] Among them, the main box-shaped structure of the traction cross beam 21 is formed by welding the cross beam bottom plate 213, the cross beam cover plate 215, and the cross beam vertical plate 217, and the side vertical plate 216 is also arranged in a welded form between the middle arc extension parts of the cross beam bottom plate 213 and the cross beam cover plate 215. The cross beam flange plate 214 with connecting holes is welded at the end of the middle arc extension part for bolt connection with the traction longitudinal beam 22.

[0037] The transverse stiffening plate 211 is arranged inside the main box structure of the traction crossbeam 21 by welding to improve its overall stiffness.

[0038] The connecting bottom plate 212 is welded to both ends of the crossbeam bottom plate 213, and the width of the joint between the connecting bottom plate 212 and the crossbeam bottom plate 213 is greater than that of other parts of the crossbeam bottom plate 213. At the same time, the connecting bottom plate 212 is provided with connecting holes for bolt connection with the side beam of the car body 1. The main function of setting a larger width is to increase the contact surface between the traction crossbeam 21 and the side beam of the car body 1 and increase the number of bolt installations. The setting of the connecting holes is to adjust the adaptation of the traction crossbeam 21 to the installation of the side beam of the car body 1. In this embodiment, the connecting bottom plate 212 is made of a thicker plate, and the main function is to ensure that the installation surfaces of the connecting bottom plates 212 at both ends of the traction crossbeam 21 are on the same reference plane as much as possible through post-welding processing.

[0039] The installation planes at both ends of the traction crossbeam 21 are higher than the surface of the middle section, and there is a height difference L. The main purpose is to avoid interference between the crossbeam flange 214 and the floor of the car body 1, and in addition, to make the center line of the traction crossbeam 21 coincide or be close to the center line of the towing rod of the rescue vehicle as much as possible.

[0040] Further, as Figure 3 shown, in this embodiment, the traction longitudinal beam 22 is formed by welding the following plates:

[0041] The longitudinal beam vertical plate 221, the longitudinal beam cover plate 222, the longitudinal beam bottom plate 223, the traction plate 224, the longitudinal beam flange 225, the sealing plate 226, and the annular patch plate 227. All the plates are integrally cut and formed, effectively reducing the number of weld joints and avoiding the problem of stress concentration, and improving the structural strength of the traction longitudinal beam 22.

[0042] Among them, the longitudinal beam vertical plate 221, the longitudinal beam cover plate 222, and the longitudinal beam bottom plate 223 are welded together to form the box structure of the traction longitudinal beam 22. A longitudinal beam flange 225 is welded at one end of the traction longitudinal beam 22 that is bolted to the traction crossbeam 21, and the longitudinal beam flange 225 is provided with connecting holes corresponding to the crossbeam flange (214); a sealing plate 226 is welded at the other end of the traction longitudinal beam 22. The traction longitudinal beam 22 and the traction crossbeam 21 are bolted together through the crossbeam flange 214 and the longitudinal beam flange 225.

[0043] The traction plate 224 and the annular reinforcing plate 227 are arranged at one end of the traction longitudinal beam 22 far from the connection with the traction cross beam 21. The fixed pin hole is arranged on the traction plate 224. The hole of the annular reinforcing plate 227 and the fixed pin hole are concentric and have the same diameter. By arranging the annular reinforcing plate 227 on the traction plate 224, the rigidity of the traction plate 224 is effectively increased.

[0044] Further, as Figure 4 shown, in this embodiment, the U-shaped bracket 23 is formed by the group welding of the U-shaped plate 231 and the rib plate 232 which are integrally cut from the blank. The bent part of the U-shaped plate 231 is integrally formed by bending, effectively reducing the number of weld seams and avoiding stress concentration, and improving the structural strength of the U-shaped bracket 23. The U-shaped plate 231 is also provided with connection holes to adapt to the traction and rescue device of the U-shaped bracket 23 relative to the vehicle body 1.

[0045] Further, as Figures 1 to 4 shown, weight reduction holes are arranged on both the traction cross beam 21 and the traction longitudinal beam 22 to meet the lightweight requirements of the maglev train.

[0046] Further, as Figure 5 shown, in the embodiment, a maglev train traction and rescue device 2 is installed under the floor of the maglev train vehicle body 1 and hidden in the front end hood 101 and the front upper skirt 102. More preferably, an operation hole is arranged on the hood 101. In case of an emergency rescue, the operation hole cover plate 103 is opened, and the traction rod of the rescue vehicle is extended into the front end of the traction longitudinal beam 22 of the maglev train traction and rescue device 2 and connected by inserting a traction pin into the fixed pin hole.

[0047] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, improvements can still be made, but these all belong to the protection scope of the present invention.
