Description
Technical Field
[0001] This utility model belongs to the field of column anti-tilting technology, and more specifically, relates to a column anti-tilting device for a retractable construction platform for railway vehicles. Background Technology
[0002] The assembly of various components of a subway car requires the use of a retractable construction platform, specifically a three-tiered platform, to complete the installation of all roof and interior components. This is done before the subway car is placed onto the support piers, such as... Figure 1 The retractable construction platform comprises a central platform 1 and an edge platform 2. The edge platform 2 retracts inward under the action of a hydraulic cylinder until it overlaps the central platform 1, thus narrowing the second-layer platform. Before the edge platform of the second-layer platform moves, the third-layer platform columns 3 and safety beams 4, which are pressed against the edge platform of the second-layer platform, need to be moved inward to a safe position. Rollers 5 are installed at the lower ends of the columns. During movement, due to the length of the safety beam 4 and the height of the third-layer platform columns 3, although the lower ends of the third-layer platform columns 3 can be connected to the fixed columns 6 on their outer sides via a telescopic connection mechanism, the movement of the third-layer platform columns 3 still presents a risk of tilting, posing a safety hazard. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an anti-tilting device for the columns of a retractable construction platform for railway vehicles, thereby solving the problem that the columns of the three-layer platform and the safety beam of the retractable construction platform for railway vehicles are prone to tilting when they move.
[0004] To achieve the above objectives, this utility model provides a column anti-tilting device for a retractable construction platform for railway vehicles, comprising:
[0005] A connecting rod, the lower end of which is used to connect to a fixed column of a retractable construction platform for railway vehicles;
[0006] An anti-roll bar, one end of which is rotatably connected to the connecting rod, and the axis of the anti-roll bar is perpendicular to the axis of the connecting rod;
[0007] A connecting component, one end of which is used to connect to the three-layer platform column of the retractable construction platform of the railway vehicle, and the other end of which is provided with a guide hole, the axis of which is perpendicular to the axis of the three-layer platform column, and the other end of the anti-tilt rod is slidably inserted into the guide hole.
[0008] Optionally, the fixed column has a hollow structure, and the lower end of the connecting rod is inserted into the fixed column.
[0009] Optionally, the lower end of the connecting rod is welded to the fixed column.
[0010] Optionally, at least two anti-roll bars are provided, with adjacent anti-roll bars spaced apart.
[0011] Optionally, a U-shaped connecting lug structure is provided on the outer side of the connecting rod, and one end of the anti-tilt rod is rotatably connected to the opening of the U-shaped connecting lug structure.
[0012] Optionally, one end of the anti-roll bar is provided with a rotating sleeve, the U-shaped connecting ear structure is provided with a first pin, and the rotating sleeve is rotatably sleeved on the outside of the first pin.
[0013] Optionally, one end of the connecting component is provided with a clamp structure, which can be fastened to the outside of the three-layer platform column.
[0014] Optionally, the clamp structure includes two U-shaped plates, each U-shaped plate having a wing plate at each end, the wing plate having fastening holes, and the two U-shaped plates being connected by fasteners.
[0015] Optionally, the other end of the connecting component is rotatably connected to a second pin, and the guide hole is radially formed within the second pin.
[0016] Optionally, the anti-roll bar has a plurality of positioning holes along its radial direction, and the plurality of positioning holes are spaced apart along the axis of the anti-roll bar.

[0017] This utility model provides an anti-tilting device for the columns of a retractable construction platform for railway vehicles. Its advantages are as follows: the anti-tilting device is connected to a fixed column via the lower end of a connecting rod, and to a three-layer platform column via one end of a connecting component. An anti-tilting rod connects the connecting rod and the connecting component. One end of the anti-tilting rod is rotatably connected to the connecting rod, while the other end slides through a guide hole at the other end of the connecting component.

[0025] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0026] like Figure 2 As shown, this utility model provides a column anti-tilting device for a retractable construction platform for railway vehicles, comprising:
[0027] Connecting rod 7, the lower end of which is used to connect to the fixed column 6 of the retractable construction platform of the railway vehicle;
[0028] Anti-roll bar 8, one end of which is rotatably connected to connecting rod 7, and the axis of anti-roll bar 8 is perpendicular to the axis of connecting rod 7;
[0029] The connecting component 9 has one end for connecting to the three-layer platform column 3 of the retractable construction platform of the railway vehicle, and the other end of the connecting component 9 is provided with a guide hole 10. The axis of the guide hole 10 is perpendicular to the axis of the three-layer platform column 3, and the other end of the anti-tilt rod 8 is slidably inserted into the guide hole 10.
[0030] Specifically, to address the problem of column tilting during movement of the three-layer platform columns 3 and safety beams 4 in existing retractable construction platforms for railway vehicles, this utility model provides an anti-tilting device for the columns of a retractable construction platform for railway vehicles. The lower end of a connecting rod 7 is connected to a fixed column 6, and one end of a connecting component 9 is connected to the three-layer platform column 3. An anti-tilting rod 8 connects the connecting rod 7 and the connecting component 9. One end of the anti-tilting rod 8 is rotatably connected to the connecting rod 7, while the other end slides through a guide hole 10 at the other end of the connecting component 9. As the three-layer platform column 3 moves, the anti-tilting rod 8 slides within the guide hole 10. Since the axis of the anti-tilting rod 8 is perpendicular to the path of the connecting rod 7, and the axis of the guide hole 10 is perpendicular to the axis of the three-layer platform column 3, it effectively guides movement and prevents tilting.
[0031] Optionally, the fixing post 6 has a hollow structure, and the lower end of the connecting rod 7 is inserted into the fixing post 6.
[0032] Specifically, the connecting rod 7 can be connected to the fixed column 6 by plugging. In order to facilitate plugging and ensure the stability of plugging, the connecting rod 7 or the lower end of the connecting rod 7 can be set to a shape that matches the hollow structure of the fixed column 6. A limiting component can also be set to limit the plugging when it is plugged in.
[0033] Optionally, the lower end of the connecting rod 7 is welded to the fixed post 6.
[0034] Specifically, the connecting rod 7 can also be fixed to the upper end of the fixed column 6 by welding. In this case, an adapter plate can be welded to the lower end of the connecting rod 7 and the adapter plate is welded to the upper end of the fixed column 6.
[0035] Optionally, at least two anti-roll bars 8 are provided, with adjacent anti-roll bars 8 spaced apart.
[0036] Specifically, the two anti-tilt rods 8 are parallel to each other and vertically spaced apart. The two anti-tilt rods 8 are connected between the connecting rod 7 fixed above the fixed column 6 and the three-layer platform column 3, forming a rectangular frame connection structure, which can further improve the anti-tilt effect on the three-layer platform column 3.
[0037] Furthermore, the anti-tilting device for the column of the retractable construction platform for railway vehicles can use one anti-tilting rod 8, or two or more anti-tilting rods 8. When using one anti-tilting rod 8, the anti-tilting rod 8 should be positioned as close as possible to the upper end of the connecting rod 7, and it can be used simultaneously with the existing telescopic connecting mechanism on the fixed column 6. In this embodiment, as shown... Figure 2 As shown, two anti-tilt bars 8 are used, which eliminates the need for the existing telescopic connection mechanism on the fixed column 6.
[0038] Optionally, a U-shaped connecting ear structure 11 is provided on the outer side of the connecting rod 7, and one end of the anti-tilt rod 8 is rotatably connected to the opening of the U-shaped connecting ear structure 11.
[0039] Specifically, the opening of the U-shaped connecting ear structure 11 faces the horizontal direction, and the anti-tilt bar 8, which is rotatably connected in the opening of the U-shaped connecting ear structure 11, can only rotate in the horizontal direction.
[0040] Optionally, one end of the anti-roll bar 8 is provided with a rotating sleeve 12, and the U-shaped connecting ear structure 11 is provided with a first pin 13, and the rotating sleeve 12 is located outside the first pin 13.
[0041] Specifically, the first pin 13 vertically penetrates the U-shaped connecting ear structure 11, and the anti-tilt rod 8 is mounted on the first pin 13 through the rotating sleeve 12 at one end of the anti-tilt rod 8, thereby achieving a rotatable connection.
[0042] In this embodiment, the upper end of the first pin 13 is provided with a first large head, and the lower end of the first pin 13 is provided with a first cotter pin hole for inserting a cotter pin.
[0043] Optionally, one end of the connecting component 9 is provided with a clamping structure 14, which can be fastened to the outside of the three-layer platform column 3.
[0044] Specifically, the connecting component 9 is connected to the three-layer platform column 3 in a convenient and adjustable position via the clamp structure 14, and its connection height should ensure that the anti-tilt bar 8 is horizontal.
[0045] Optionally, the clamp structure 14 includes two U-shaped plates, each U-shaped plate having a wing plate at each end, the wing plate having fastening holes, and the two U-shaped plates being connected by fasteners.
[0046] Specifically, the two U-shaped plates of the clamp structure 14 are connected and secured by fasteners, and can be tightly clamped onto the three-layer platform column 3.
[0047] Optionally, the other end of the connecting component 9 is rotatably connected to a second pin 15, and a guide hole 10 is radially formed inside the second pin 15.
[0048] Specifically, two horizontal ear plates are connected to a U-shaped plate of the clamp structure 14. The two horizontal ear plates are arranged vertically at intervals. The second pin 15 passes vertically through the two horizontal ear plates. The guide hole 10 on the second pin 15 is located between the two horizontal ear plates. The anti-tilt rod 8 passes through the guide hole 10.
[0049] In this embodiment, the upper end of the second pin 15 is provided with a second large head, and the lower end of the second pin 15 is provided with a second cotter pin hole for inserting a cotter pin.
[0050] Optionally, the anti-roll bar 8 has a plurality of positioning holes 16 along its radial direction. The plurality of positioning holes 16 are spaced apart along the axis of the anti-roll bar 8. The positioning holes 16 are used to pass through positioning pins to limit the movement between the anti-roll bar 8 and the connecting component 9.
[0051] Specifically, when the three-layer platform column 3 moves, the connecting component 9 slides along the anti-tilt bar 8. When it is about to be in place, the connecting component 9 can be moved between two adjacent positioning holes 16, and positioning pins are inserted on both sides of the connecting component 9. The positioning pins are used to position the connecting component 9, thereby achieving the limitation of the three-layer platform column 3.
[0052] In summary, when using the anti-tilting device for the retractable construction platform of railway vehicles provided by this utility model, if... Figure 3 As shown, the lower end of the connecting rod 7 is welded to the fixed column 6, so that the connecting rod 7 and the fixed column 6 are coaxial and above the fixed column 6. The anti-tilt rod 8 is inserted into the guide hole 10 of the connecting component 9, and the connecting component 9 is connected to the three-layer platform column 3 by the clamp structure 14. Before the railway vehicle lands on the pier, when the edge platform 2 of the second-layer moving platform needs to be retracted inward, the three-layer platform column 3 is moved inward first. As the three-layer platform column 3 moves, the connecting component 9 moves along the axial direction of the anti-tilt rod 8. Under the guidance of the anti-tilt rod 8, the three-layer platform column 3 moves, and the three-layer platform column 3 is not easy to tilt, which can improve safety. When the three-layer platform column 3 is about to be in place, the connecting component 9 is moved between two adjacent positioning holes 16, and positioning pins are inserted on both sides of the connecting component 9 to position the connecting component 9.
[0053] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
