Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle wheel set support anti-slip devices, and in particular relates to a rail vehicle wheel set support device. Background Art

[0002] When traditional rail vehicles, rail vehicle running gear assemblies and wheelsets are stored on two rail tracks of the same gauge that meet the requirements of vehicle wheelsets, appropriate anti-slip measures must be set to restrict them. If they are parked for a long time, the existing rail platform space will be occupied, and the effectiveness of anti-slip measures must be checked and confirmed on a daily basis. If the inspection and monitoring or anti-slip measures are not in place, there will be a safety hazard of slipping. In the prior art, the structure of the rail vehicle wheel is as follows: Figure 1 As shown, the wheel tread is an arc shape as a whole, and the inner side of the tread is the wheel rim. The setting of the wheel rim makes the wheel tread slightly tapered and larger on the inner side; the inner and outer sides of the rim are both vertical vertical planes; in addition, the outer side of the wheel spoke is concave. Affected by the structure of the rail vehicle wheel, when the rail vehicle, the rail vehicle running gear assembly and the wheelset are transported on non-railway lines, the bottom surface of the wheelset has a tendency to rotate, and the transportation platform needs to be modified and equipped with appropriate fixed anti-slip devices to prevent the risk of falling due to movement during transportation; especially when there is a switch in transportation mode during transportation (such as: road truck to cargo ship shipping or cargo ship shipping to road truck transportation), it is necessary to load and unload and switch the transportation platform, which requires the addition of corresponding fixed anti-slip devices to each transportation platform. Every link must be in place, otherwise there will be safety hazards or delays in project progress, which is very troublesome, time-consuming and labor-intensive.

[0003] Anti-slip devices are disclosed in the prior art. For example, CN207000473U discloses an anti-slip device for railway locomotives. Although the anti-slip device can achieve the anti-slip effect, the anti-slip device is separated from the wheel and cannot be transferred with the vehicle or the wheelset. It is not suitable for anti-slipping of vehicles during transportation, especially for anti-slipping of vehicles that need to switch transportation modes.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The utility model aims to provide a rail vehicle wheelset supporting device to solve the problems existing in the prior art in the background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rail vehicle wheelset supporting device, comprising:

[0008] A bearing assembly, the bearing assembly comprising a horizontally arranged bearing substrate, a support box symmetrically arranged at two ends of the bearing substrate, and a support pad fixed in the support box;

[0009] An outer locking assembly, the outer locking assembly comprising a vertical locking mounting seat fixed to the outer side of the middle portion of the carrier base plate, a transition connecting seat fixed to the top of the locking mounting seat by bolts, and a locking limit plate fixed to the bottom of the horizontal section of the transition connecting seat by bolts;

[0010] The inner limit assembly includes a vertical limit mounting seat fixed to the inner side of the middle part of the supporting base plate and an inner limit plate fixed to the inner side of the limit mounting seat by bolts.

[0011] Preferably, the support box is provided with a downwardly inclined slope on one side close to the middle of the carrier substrate; the support pad is higher than the support box and the support pad is provided with a curved surface corresponding to the outer diameter of the wheel tread of the rail vehicle wheelset on one side close to the middle of the carrier substrate.

[0012] Preferably, the inner end of the locking and limiting plate faces the wheel spoke plate of the rail vehicle wheelset; and the lower surface of the locking and limiting plate is close to the inner wall of the wheel rim of the rail vehicle wheelset.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The utility model symmetrically arranges two support boxes and support pads on the supporting base plate according to the overall arc surface feature of the wheel tread, which can effectively prevent the wheel from rotating freely, thereby effectively ensuring that the wheel is not damaged by bumps during long-term storage or transportation; in addition, according to the slight tapering of the wheel tread (larger on the inner side) and the vertical vertical surface feature of the inner side of the rim, an inner limit assembly is arranged on the inner side of the supporting base plate. In actual use, the inner limit plate is made of non-metallic materials such as nylon, which can effectively ensure that the wheel is not damaged by bumps during long-term storage or transportation; secondly According to the characteristics that the outer side of the wheel rim is a vertical vertical plane and the outer side of the spoke plate is concave, an outer locking component is arranged on the outer side of the carrier base plate. In actual use, the locking limit plate is made of non-metallic materials such as nylon, and the inner end of the locking limit plate faces the spoke plate of the rail vehicle wheelset wheel, and the lower surface of the locking limit plate is close to the inner wall of the rim of the rail vehicle wheelset wheel. During the hoisting process of the rail vehicle complete vehicle, the rail vehicle running gear assembly and the wheelset as a whole, the locking limit plate will be stuck on the outer side of the spoke plate and the inner wall of the rim, and then the support device of the present application will move along with it. Moreover, when hoisting and falling, the support device of the present application can land first, and then fix the wheels of the rail vehicle wheelset to prevent them from slipping, so that the storage of the rail vehicle complete vehicle, the rail vehicle running gear assembly and the wheelset is not restricted and dependent on the site.

[0015] (2) The support device of the utility model is easy to disassemble and recycle, and can be applied to the storage and transportation of different types of rail vehicles, rail vehicle running gear assemblies and wheelsets, and ensures that the wheelsets will not be damaged during storage, transportation and lifting.

[0016] (3) The support device of the utility model can solve the problem of repeated labor in loading and unloading and fixing anti-slip measures during non-railway transportation, and can ensure that the anti-slip measures can be installed in place at one time, saving labor and improving process safety performance.

[0033] The outer locking assembly 2 includes a vertical locking mounting seat 21 fixed to the outer side of the middle of the carrier base plate 11, a transition connection seat 22 fixed to the top of the locking mounting seat 21 by bolts, and a locking limit plate 23 fixed to the bottom of the horizontal section of the transition connection seat 22 by bolts; wherein the inner end of the locking limit plate 23 faces the wheel spoke plate 102 of the wheelset of the rail vehicle 100; and the lower surface of the locking limit plate 23 is close to the inner wall of the wheel rim 103 of the wheelset of the rail vehicle 100;

[0034] The inner limit assembly 3 includes a vertical limit mounting seat 31 fixed to the inner side of the middle part of the supporting base plate 11 and an inner limit plate 32 fixed to the inner side of the limit mounting seat 31 by bolts.

[0035] When in use, the inner limit plate 32 is fixed to the inner side of the limit mounting seat 31 by means of bolts, the transition connection seat 22 is removed, the limit plate 23 is locked, and the supporting base plate 11 and the remaining other components are placed as a whole under the wheel of the rail vehicle wheelset.
