[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 5 As shown, the rail vehicle bogie axle box supporting device of this embodiment includes a base plate 10, on which a column 20 is fixedly provided, and an upper end of the column 20 is sleeved with a connecting frame 30 that can slide up and down; L-shaped support frames 40 are respectively fixedly provided at both ends of the connecting frame 30, and the two support frames 40 are arranged opposite to each other; an elastic member 50 is provided between the column 20 and the connecting frame 30, and the elastic member 50 is used to elastically support the connecting frame 30.

[0023] The rail vehicle bogie axle box support device of this embodiment has a simple structure and is easy to operate, and can provide stable and effective support for axle boxes of various models. The support device of this embodiment can provide stable and effective support for the axle box when the bogie is completed, avoiding the axle box from tilting, and is convenient for use with the bogie automatic completion equipment. There is no need to hoist the wheelset axle box assembly and frame to the completion platform for completion operations, and it can be directly used for the bogie completion operation, thereby greatly improving the operating efficiency of the bogie completion process, reducing labor intensity, and effectively avoiding the safety hazards caused by manual straightening of the axle box when the bogie is completed.

[0024] The bottom of the base plate 10 is provided with a plurality of universal wheels 11, which are universal wheels with brake devices commonly used in the technical field and are not specifically limited here. The support device of this embodiment is supported by a plurality of universal wheels 11, so that the support is more stable and firm, and the support device can be freely moved on the ground.

[0025] There are two columns 20, and the two columns 20 are symmetrically fixed on the bottom plate 10. Specifically, the column 20 is an integral piece, and can be integrally formed by a processing technology. The column 20 includes a fixed section 21 and a guide section 22 from bottom to top, and the diameter of the fixed section 21 is larger than the diameter of the guide section 22. The fixed section 21 is fixed on the bottom plate 10, and the fixing method can be welding or other fixing methods commonly used in the art, which are not specifically limited here.

[0026] The elastic member 50 is a spring, which is sleeved on the guide section 22, with the bottom of the spring abutting against the fixed section 21, and the top of the spring abutting against the connecting frame 30. When the connecting frame 30 and the support frame 40 slide downward, the spring can be pressed down to compress the spring. The compression elastic force of the spring can play an elastic supporting role for the connecting frame 30 and the support frame 40, so that the supporting device of this embodiment can play a stable and effective supporting role for the shaft box body.

[0027] A through hole 31 is provided on the connecting frame 30, and the aperture of the through hole 31 is larger than the diameter of the guide section 22. The guide section 22 passes through the through hole 31, and the connecting frame 30 can slide up and down along the guide section 22; the guide section 22 can also guide the up and down sliding of the connecting frame 30, so that the connecting frame 30 can slide up and down along the guide section 22 stably and effectively.

[0028] A blocking piece 23 is provided at the top of the guide section 22. The diameter of the blocking piece 23 is larger than the aperture of the through hole 31, which can limit the connection frame 30 and prevent the connection frame 30 from escaping from the guide section 22 when sliding upward.

[0029] The support frame 40 is an integral part and can be integrally formed by a processing technology. The support frame 40 includes a vertical support plate 41, and a horizontal support plate 42 is vertically provided on the top of the vertical support plate 41. The bottom of the vertical support plate 41 is fixed to the connection frame 30, and the fixing method can be welding or other fixing methods commonly used in the art, which are not specifically limited here. The horizontal support plates 42 of the two support frames 40 are arranged opposite to each other, which can provide a stable and effective support for the shaft box body 60.

[0030] The transverse support plate 42 is parallel to the connecting frame 30, and the distance between the transverse support plate 42 and the connecting frame 30 is greater than the length of the guide section 22, which can prevent the guide section 22 from protruding from the transverse support plate 42 when the connecting frame 30 moves downward, thereby ensuring that the transverse support plate 42 can provide stable and effective support for the axle box body 60.

[0031] The surface of the transverse support plate 42 is provided with a rubber cushion layer (not shown in the figure), which can protect the shaft box body 60 and prevent the transverse support plate 42 from scratching the shaft box body 60.

[0032] Two handles 32 are fixedly provided on the connection frame 30 , which can facilitate the support device of this embodiment to be moved by hand, and can also facilitate the connection frame 30 to be pressed down or lifted by holding the handles 32 .

[0033] The method for using the rail vehicle bogie axle box support device comprises: moving the support device of the present embodiment to the bottom of the rail vehicle bogie axle box 60, holding the handle 32 on the connecting frame 30 and pressing the connecting frame 30 downward, so that the connecting frame 30 and the support frame 40 move downward, and when the support frame 40 moves down to the bottom of the spring tray 61 of the axle box 60, the handle 32 is released, and the connecting frame 30 and the support frame 40 automatically slide upward under the action of the elastic member 50, so that the transverse support plate 42 abuts against the bottom of the spring tray 61, thereby supporting the axle box 60; placing axle box springs 62 at both ends of the spring tray 61, Since the axle box body 60 is supported by the support device of the present embodiment, the axle box body 60 will not tilt after the axle box spring 62 is placed; after the axle box spring 62 is placed, the bogie assembly is dropped onto the wheelset assembly 63. When dropping the bogie assembly, due to the support of the support device of the present embodiment, there is no need to manually straighten the axle box body, which not only improves the efficiency of the bogie completion but also effectively solves the safety hazard caused by manually straightening the axle box body when the bogie is completed.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
