Technical Field

[0001] The utility model relates to the field of subway train maintenance, in particular to a subway train bogie supporting device. Background Art

[0002] As there are more and more types of subway trains, the maintenance equipment in the existing subway maintenance bases cannot meet the maintenance requirements of all models.

[0003] When the bogie is repaired, some special supporting tools are needed for support and fixation. Generally, in the prior art, the supporting tooling usually includes a frame composed of a crossbeam and a longitudinal beam, and a positioning groove set on the frame. The positioning groove matches the wheel, so that the entire bogie can be fixed by fixing the wheel.

[0004] For this reason, the depth of the positioning groove needs to be set deep enough to achieve stable fixation of the bogie. In this way, the thickness of the overall frame is relatively large, which may cause the frame to crack easily if lateral forces such as shear force occur under extrusion. Utility Model Content

[0005] The purpose of the utility model is to provide a subway train bogie support device, which provides support from the front and rear sides of the positioning groove by arranging elastic positioning columns, and further prevents lateral movement by relying on the horizontal component of the formed supporting force, thereby reducing the overall thickness of the frame and avoiding cracking caused by excessive thickness of the frame.

[0010] The elastic positioning column includes a column and a spring. A slide hole is provided on the base block. One end of the column is inserted into the slide hole, and the other end passes through the top plate and protrudes from the surface of the top plate. The spring is sleeved on the column, and the two ends are supported by the upper surface of the base block and the lower surface of the top plate respectively.

[0011] The portion of the column located in the slideway hole is greater than 50% of the entire length of the column.

[0012] The top of the column is provided with an anti-slip elastic head.

[0013] The four support blocks are respectively located at the connection between each longitudinal beam and the cross beam.

[0014] Both ends of the positioning groove are provided with slopes.

[0015] A forklift hole is provided on the crossbeam.

[0016] A triangular reinforcement plate is provided between the longitudinal beam and the cross beam.

[0021] 4. The portion of the column located in the slide hole is greater than 50% of the total length of the column, so that it can have a certain deviation correction ability and avoid excessive shear torque on the column produced by the opening of the slide hole.

[0022] 5. The top of the column is equipped with an anti-slip elastic head, which can provide greater resistance and improve stability.

[0023] 6. Slopes are provided at both ends of the positioning groove to prevent adhesion when the bogie is separated from the supporting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] A subway train bogie support device, such as Figure 1 and Figure 2 As shown, it includes a frame composed of a longitudinal beam 3 and a transverse beam 4, and four support blocks 5 arranged on the frame, the bottom of the support block 5 is provided with a support foot 6, and the top of the support block 5 is provided with a positioning groove 1 for matching the wheel on the bogie, and elastic positioning columns 2 are provided at both ends of the positioning groove 1. The positioning groove 1 is axially symmetrical, and the symmetry axis is parallel to the radial section of the wheel. Any point on the axis of an elastic positioning column 2 on the same support block 5 and the line connecting any point on the axis of another elastic positioning column 2 are located in the same plane as the symmetry axis of the positioning groove 1.

[0036] By arranging elastic positioning columns 2 to provide support for the wheel from the front and rear sides of the positioning groove 1, the horizontal component of the formed supporting force is further used to prevent lateral movement, thereby reducing the overall thickness of the frame and avoiding cracking caused by excessive frame thickness.

[0037] Similar to the prior art, two longitudinal beams 3 and two transverse beams 4 are provided, and the longitudinal beam 3 is parallel to the wheel axle of the bogie.

[0038] Furthermore, in some embodiments, Figure 2 As shown, the support block 5 includes a base block 5-1 and a top plate 5-2. The top plate is arranged on the outer side of the upper surface of the base block 5-1 through a pad block 5-3. The positioning groove 1 and the elastic positioning column 2 are both arranged on the top plate 5-2, wherein the outer side is the side away from another support block 5 on the same longitudinal beam 3.

[0039] On the basis of setting the elastic positioning column 2, the top plate 5-2 is installed by setting the top plate to be raised by the raising block 5-3, so that a certain elastic buffer space can be reserved to improve the durability of the supporting device.

[0040] like Figure 3As shown, the elastic positioning column 2 includes a column 2-1 and a spring 2-2. A slide hole is provided on the base block 5-1. One end of the column 2-1 is inserted into the slide hole, and the other end passes through the top plate 5-2 and protrudes from the surface of the top plate 5-2. The spring 2-2 is sleeved on the column 2-1, and the two ends are supported by the upper surface of the base block 5-1 and the lower surface of the top plate 5-2 respectively. By means of the spring 2-2 and the column 2-1, the structural strength and durability can be improved by relying on the solid support force of the base block 5-1.

[0041] In addition, in some embodiments, the portion of the column 2-1 located in the slide hole is greater than 50% of the total length of the column 2-1, so that it can have a certain deviation correction ability and avoid the opening of the slide hole from generating excessive shear torque on the column.

[0042] Furthermore, in some embodiments, a non-slip elastic head is provided on the top of the column 2-1, which can provide greater resistance and improve stability.

[0043] In this embodiment, four support blocks 5 are respectively located at the connection between each longitudinal beam 3 and the cross beam 4, so as to improve space utilization.

[0044] Furthermore, in this embodiment, slopes are provided at both ends of the positioning groove 1, so that the portion of the edge embedded in the wheel is smaller, thereby avoiding adhesion when the bogie is separated from the supporting device.

[0045] In addition, in some embodiments, a forklift hole is provided on the cross beam 4 to facilitate the operation of a forklift, and in normal circumstances, a triangular reinforcement plate is provided between the longitudinal beam 3 and the cross beam 4 to improve strength.

[0046] The operation process of the present application is as follows: the operator uses a lifting device or a shovel or a crane to align the outer shell of the support block 5 with the original top column of the lifting machine, and it can be used after it is dropped. Due to the role of the longitudinal beam 3 and the cross beam 4, there is no need to fix the tooling additionally. After the bogie is placed on it, the positioning groove 1 and the elastic positioning column 2 can play a good role in limiting.
