Description

Technical Field

[0001] The utility model relates to the technical field of ferry plate composition, in particular to a multi-piece ferry plate mechanism for a windshield in a high-speed train set. Background Art

[0002] A multi-piece bridge mechanism for a windshield in a high-speed train set is usually used for passenger doors or connections of high-speed trains, in order to provide higher safety and convenience during train operation.

[0003] The internal windshield fender mechanism is a walking platform between the two passenger cars. When the train is running on a curved line, the fender mechanism will move synchronously with the relative movement between the two car bodies. The existing high-speed EMU internal windshield fender mechanism needs to reserve a large hole overlap space at the car end. It cannot stretch or compress itself and only has an offset function. It needs to rely on the reserved leaf spring inside the car body for reset, which will not only affect the interior layout design, but also may lead to the complexity of the car body structure. Therefore, it is necessary to redesign a high-speed EMU internal windshield multi-piece fender mechanism to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a multi-piece bridge mechanism for the windshield in a high-speed train set.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is provided with a plurality of support plates, each of which is connected to the rear of the two supports, and the support plates are connected to the rear of the two supports at two ends.

[0007] Preferably, the supporting mechanism comprises a plurality of groups of rollers slidably connected in a slide groove, the number of the plurality of groups of rollers is consistent with the number of hinge points in the connecting rod mechanism, and the plurality of groups of rollers are installed one-to-one at the wear-resistant sleeves at the hinge points in the connecting rod mechanism, and the outer wall of the roller is in contact with the inner wall of the slide groove.

[0008] Preferably, a support beam is fixedly connected below the support plate, and the support beam is fixedly connected to both the first U-shaped beam and the second U-shaped beam.

[0009] Preferably, bearing assemblies are installed at both ends of the U-shaped beam 1 and the U-shaped beam 2.

[0010] Preferably, the connecting rod 1 and the connecting rod 2 at the left and right ends both extend to the internal mounting seats of the U-shaped beam 1 and the U-shaped beam 2.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model provides a connecting rod mechanism and other devices, so that the upper ferry board and the lower ferry board can be compactly stored and unfolded to form a larger transition space through the extension and folding of the connecting rod mechanism, which will greatly reduce the space waste between the car bodies, which means that more space can be used for passengers and luggage configuration, thereby improving the capacity and comfort of the car.

[0013] 2. The utility model can put the ferry board in a more stable state by setting the upper ferry board and the lower ferry board. No matter the train is running in a straight line or turning a curve, the upper ferry board and the lower ferry board can remain stable, providing a larger and more stable walking platform when extended, and reducing the encroachment on the passenger area when folded, reducing the possibility of passengers being squeezed, and effectively improving passenger safety.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-6 A multi-piece cross-plate mechanism for a windshield in a high-speed train unit includes a U-shaped beam 1 and a U-shaped beam 2 7, two groups of support plates 4 are fixedly connected between the U-shaped beam 1 and the U-shaped beam 2 7, two ends of the two groups of support plates 4 are respectively fixedly connected to the inner walls of the U-shaped beam 1 and the U-shaped beam 2 7, a slide groove 9 is opened above the two groups of support plates 4, a connecting rod mechanism 5 is installed above the slide groove 9, and the connecting rod mechanism 5 is composed of multiple groups of connecting rods 1 501 and connecting rods 2 502, multiple groups of connecting rods 1 501 and connecting rods 2 502 are arranged in pairs in a prism shape, and each pair of connecting rods 1 501 and connecting rods 2 502 are crossed in the middle. A common hinge point is provided at the point, and the hinge points are connected through wear-resistant bushings. An upper ferry board 2 and a lower ferry board 3 are arranged crosswise at the hinge point in the connecting rod mechanism 5. The lower end surface of the upper ferry board 2 contacts the upper end surface of the adjacent lower ferry board 3, and they are slidably connected to each other. A supporting mechanism for supporting the connecting rod mechanism 5 is installed in the slide groove 9. The supporting mechanism includes multiple groups of rollers 10 slidably connected in the slide groove 9. The number of the multiple groups of rollers 10 is consistent with the number of hinge points in the connecting rod mechanism 5, and the multiple groups of rollers 10 are installed one by one at the wear-resistant bushings at the hinge points in the connecting rod mechanism 5, and the outer wall of the roller 10 contacts the inner wall of the slide groove 9.

[0023] It should be noted that the loads of the upper ferry plate 2 and the lower ferry plate 3 are transmitted to the support plate 4 through the connecting rod mechanism 5. The wear between the upper ferry plate 2 and the lower ferry plate 3 will not cause sagging or shaking. In addition, when replacing the wear-resistant sleeve on the connecting rod mechanism 5 structure, it is only necessary to remove the U-beam 1 and the mounting seat in the U-beam 2 7, and remove the support plate 4 to replace the wear-resistant sleeve of the connecting rod mechanism 5. There is no need to disassemble each upper ferry plate 2 and the lower ferry plate 3, and the maintenance operation is more convenient.

[0024] A support beam 8 is fixedly connected below the support plate 4, and the support beam 8 is fixedly connected to both the U-shaped beam 1 and the U-shaped beam 2 7;

[0025] It should be noted that the upper ferry board 2 and the lower ferry board 3 are evenly distributed by relying on the internal connecting rod structure 5. The connecting rod structure 5 falls on the support plate 4. The roller 10 on the support plate 4 can move synchronously with the connecting rod structure 5. The support plate 4 is provided with a slide groove 9. The roller 10 on the node at the bottom hinge of the connecting rod 1 501 and the connecting rod 2 502 moves in the slide groove 9, and at the same time provides rigid support for the whole set of ferry boards to prevent the upper ferry board 2 and the lower ferry board 3 from sinking under the load.

[0026] Bearing assemblies 6 are installed at both ends of the U-shaped beam 1 and the U-shaped beam 2 7, and are characterized in that the connecting rod 1 501 and the connecting rod 2 502 at the left and right ends extend to the internal mounting seats of the U-shaped beam 1 and the U-shaped beam 2 7.

[0027] In the utility model, the windshield ferry board in the device excluding the hook is composed of five upper ferry boards 2 and lower ferry boards 3 on the upper surface, and two sets of connecting rod mechanisms 5 are arranged on the U-beam 1 and the U-beam 2 7 at both ends. When passing through the curve, the connecting rod mechanism 5 is relied on to move and reset, and the bottom support plate 4 and the support beam 8 provide bearing. In addition to being able to do offset movement, it can also do stretching and compression movement. This structure can set a larger net passing width in the smaller inner space of the inner windshield. When the train passes through the curve, under the condition of the same side pull displacement, the more the number of overlapping plates, the less the dislocation displacement of each plate, and the smaller the width of the skirt that blocks the step gap between the upper ferry board 2 and the lower ferry board 3. The common ferry board on the market is a three-piece structure, which is a seven-piece structure with the U-beams at both ends.

[0028] When in use, the connecting rod mechanism 5 is in a compressed or closed state, and all the connecting rods 1 501 and 2 502 are folded together to form a compact structure, which can be started by a driving mechanism such as a motor or a hydraulic cylinder. By applying force to a specific hinge point, the connecting rods 1 501 and 2 502 begin to rotate and unfold along the hinge point under the force of the driving mechanism, and the distance between the hinge points increases. Each connecting rod 1 501 and connecting rod 2 502 gradually unfolds to the maximum limit, presenting a stretched shape, forming a larger rectangular or diamond structure.

[0029] During the contraction process: the link mechanism 5 is in a fully expanded state, all the links 1 501 and 2 502 are stretched out to form a larger space, and the driving mechanism acts in the opposite direction to push a specific hinge point, so that the link mechanism 5 begins to contract. During this process, each link 1 501 and 2 502 rotates along the hinge point and gradually moves closer, and the distance between the hinge points is reduced until each link 1 501 and 2 502 are finally completely folded together to form a compact structure.

[0030] The newly designed ferry linkage mechanism 5 can be flexibly stretched into a larger transition space when needed and compactly stored when not needed through the connection rod 1 501 and the connection rod 2 502 and the rotation expansion and contraction method through the hinge point. This greatly optimizes the internal space utilization of the car. At the same time, after adopting the new retractable ferry design, it is no longer necessary to reserve large holes and reset spaces in the car body, which reduces the complexity of the car body design and the manufacturing cost, releases more space for passengers and cargo, and improves the actual utilization efficiency of the interior space. At the same time, it eliminates the need to rely on the car body leaf spring to reset, so that the upper ferry 2 and the lower ferry 3 can be freely extended and folded, thereby eliminating the complex reset mechanism and reducing the burden of the car body design and the subsequent maintenance difficulty.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
