Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a supporting device, application and method for supporting a cross beam of a train underframe. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The train chassis includes a large beam and a small beam. The width of the small beam is narrower than that of the large beam. In the production process, more welding processes are involved. For example, when the stainless steel chassis is installed, the connection between the corrugated plate and the frame is mainly through automatic spot welding equipment and TI GSPOT (gas tungsten arc welding) manual spot welding. The single-sided double-spot equipment automatic spot welding can only be performed on the large beam area, and the small beam cannot withstand the pressure of the spot welding equipment due to its own insufficient strength, so it can only be spot welded manually by TI GSPOT. In the process of manual TI GSPOT spot welding, due to human factors, etc., the welding spot forming effect is often poor. In the welding process of automatic spot welding equipment such as single-sided double-spot equipment, although the large beam can withstand the pressure of the spot welding equipment, there is no stable support at the bottom, and the appearance quality is often poor, resulting in rework and repair of the welding point, which needs to be repaired by plug welding after drilling, seriously affecting the construction efficiency and product quality.

[0004] Of course, the above problems also exist during the welding construction of other components, and support devices are needed to facilitate the smooth progress of automatic welding or manual welding.

[0005] Chinese patent application CN202210963650.0, with an application date of August 11, 2022, discloses a method for manufacturing a subway vehicle underframe and a tool for manufacturing the same, which are used for spot welding and fixing side beams, end beams and tie-downs. Specifically, a tightening device is used for tightening. Because it takes into account the welding of the entire underframe, in order to adapt to the length of the underframe, the entire device is arranged along the length direction of the underframe. It can be used for spot welding construction of the underframe side beams and end beams, but when used for the underframe installation, it has a long structure and occupies a large area, and cannot support the crossbeams of the underframe; and because it has a large number of support members, if it is used for the underframe installation, it is not conducive to adjusting the distance between two adjacent support members, because the number of guide rails is limited and the crossbeams cannot be effectively supported, and there are many train models, and the position of the support members cannot be quickly adjusted. This has poor targeting and leads to low production efficiency.

[0006] In addition, the existing chassis support device is not provided with a positioning component, and the movement of the support member depends only on experience, which has the problem of low movement speed and movement accuracy. Summary of the invention

[0050] As introduced in the background technology, there is a problem in the prior art that the underframe welding equipment is long, occupies a large area and cannot be applied to some welding sites. In order to solve the above technical problems, the present invention proposes a supporting device for supporting the underframe crossbeam of a train.

[0051] Embodiment 1

[0052] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a supporting device for supporting a cross beam of a train underframe comprises at least two groups of supporting units, wherein the supporting units are arranged along the width direction of the train underframe, and the distance between two adjacent supporting units is adjusted according to the position of the cross beam in the underframe. The supporting units comprise at least two mutually parallel guide rail members 1, and the two adjacent guide rail members 1 are arranged at a distance, and each guide rail member 1 is provided with at least two supporting members 2, and a plurality of groups of supporting units cooperate with each other to support the underframe through a plurality of supporting members 2, and each supporting member 2 can maintain a set pressure to support the cross beam of the underframe, and the supporting member 2 can move along the guide rail member 1 and can be locked relative to the position of the guide rail member 1, and a positioning component 3 is provided at each guide rail member 1, and the positioning component 3 can move along the guide rail member 1 to position the support member 2 at the guide rail member 1.

[0053] In the present embodiment, the base frame is supported by two groups of support units along the width direction of the base frame, and the two groups of support units support the base frame cross beams. Three support members 2 are arranged at each guide rail member 1 of each support unit. In other examples, the number of support members 2 can also be two or four. Considering the stability of the structural arrangement, in some examples, a support frame is further arranged between the two groups of support units, and the bottom of the support frame is fixed to the ground, and a support pad is arranged on the top of the support frame, which contacts with the base frame through the support pad. An end side support frame is also arranged on the outer side of the support unit away from the support frame, and the end side support frame supports the end side of the base frame.

[0054] It is easy to understand that, because of the different train models, the position and shape of the crossbeam at the corresponding underframe are different. Because of the different crossbeam positions, the position between the two groups of support units can be adjusted. Because of the different shapes of the crossbeams, the position of the support members 2 can be moved along the guide rail member, and one crossbeam is supported by two groups of support members 2. When the guide rail member is provided with three support members 2, the position of each support member is determined, and the underframe crossbeam is supported by any two support members 2 to achieve rapid switching of the underframes of different train models.

A sliding guide rail 1-3 is set at the open end of the U-shaped seat. The length of the sliding guide rail 1-3 is the same as the length of the U-shaped seat 1-2. The width of the sliding guide rail 1-3 is smaller than the width of the open end of the U-shaped seat, and the width of the supporting cylinder in the supporting component is less than or equal to the width of the open end of the U-shaped seat to facilitate the locking of the locking component. The bottom of the supporting component 2 cooperates with the sliding guide rail, and the positioning component can move along the side wall of the U-shaped seat 1-2.

[0056] It should be noted that there are multiple mounting seats 1 on the outside of the guide rail component 1, and the mounting seats can be connected to the ground. Specifically, there can be three mounting seats. The mounting seats 1-1 are arranged parallel to each other, and the length of the mounting seats is greater than the distance between the outer sides of the two guide rail components. The mounting seats 1-1 are provided with threaded holes so that the mounting seats can be fixed to the ground; and a connecting frame 1-4 is also connected between the two guide rail components in the support unit to connect the two guide rail components.

A through hole is set on one side wall of the snap-fitting component 3-2, and the through hole is connected to the opening. An adjusting component such as an adjusting bolt 3-4 can pass through the through hole and contact the side wall of the U-shaped seat. After the position of the positioning component 3 is determined, the adjusting component can be locked. A third locking nut 3-3 is circumferentially set on the adjusting component. After the end of the adjusting bolt is in close contact with the side wall of the U-shaped seat, it is locked by the third locking nut.

The rotating member 3-5 can specifically be a rotating plate. The rotating member 3-5 can rotate relative to the engaging member. Specifically, the rotating member 3-5 is connected to the engaging member 3-5 through a pin shaft. After the position of the positioning component 3 is determined, the rotating member is rotated downward and contacts the outer end face of the adjusting bolt to prevent the adjusting bolt from being touched by the outside.

[0064] It is easy to understand that a bottom support plate 2-5 is arranged at the bottom of the support cylinder 2-4, the width of the bottom support plate 2-5 is less than or equal to the width of the opening of the U-shaped seat, and can contact the inner wall of the positioning component, and the inner wall of the positioning component 3 positions the bottom support plate 2-5 to realize the positioning of the support member, and a slider 2-6 is arranged below the bottom support plate 2-5, and the slider 2-6 is provided with a recess, and the shape of the recess is adapted to the shape of the sliding guide rail to realize the movement of the support cylinder relative to the guide rail member, and when the sliding guide rail is a T-shaped sliding guide rail, the longitudinal cross-section of the recess is also T-shaped.
