Description

Technical Field

[0001] This utility model relates to the field of train cable support devices, and in particular to a multi-carriage cable support frame for trains. Background Technology

[0002] The connection between multiple train cars mainly relies on two key components: the coupler and the connecting passage. The coupler ensures the mechanical connection between the cars, while the connecting passage is located at the connection between two cars and serves as a corridor for passengers. The connecting passage is a flexible connection, allowing for a certain degree of relative movement between the two cars, enabling the train to turn flexibly when passing through curves and maintain smooth operation.

[0003] Because of the relative movement at the connection points between train carriages, cables spanning carriages need to maintain reliability under frequent vibration, expansion, contraction, and bending. Currently, the common method for securing cables on trains is to use clamps to bundle the cables into cable bundles, which are then bent and placed above the folding canopy in the passageway to accommodate the relative movement between carriages during turns. However, this method of bundling cables directly above the folding canopy means that when the train turns, the relative movement between carriages causes relative movement between the cables and the folding canopy, leading to cable wear or displacement. In severe cases, the folding canopy may clamp the cables, pulling on them and causing damage. Utility Model Content

[0004] In view of this, the main purpose of this utility model is to provide a multi-carriage cable support frame to solve the problem in the prior art where the cable is placed directly above the folding canopy in the cable bundling method. When the train turns, the relative movement between the carriages causes the cable to move relative to the folding canopy, resulting in cable wear or displacement. In severe cases, the folding canopy may clamp the cable, thereby pulling on the cable and causing damage.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A multi-carriage cable support frame includes: an elastic support plate and a fixing device. The elastic support plate is arc-shaped, and its two ends are fixedly connected to two carriages respectively. The cable is supported on the side of the elastic support plate by the fixing device.

[0006] In a preferred embodiment, the device further includes a suspension device comprising a roller and a guide rod. The roller is rotatably connected to the middle of an elastic support plate, and the guide rod is fixedly connected to a folding canopy in the middle of the two carriages. The roller is located at the upper end of the guide rod, and the roller is in rolling connection with the guide rod.

[0007] In a preferred embodiment, the suspension device further includes a roller frame, wherein the roller is rotatably connected to the roller frame, and the roller frame is slidably connected to the elastic support plate.

[0008] In a preferred embodiment, the roller frame has a through groove, and the elastic support piece passes through the through groove, allowing the roller frame to slide on the outside of the elastic support piece.

[0009] In a preferred embodiment, the system further includes a fixed bracket, wherein the two ends of the elastic support piece are respectively fixedly connected to the two carriages via two fixed brackets, one end of the fixed bracket is fixedly connected to the elastic support piece, and the other end of the fixed bracket is fixedly connected to the carriage. In a preferred embodiment, the number of fixing devices is 4-10, and each fixing device includes a bracket and a stop bar. The bracket is fixedly connected to the elastic support plate, and the two ends of the stop bar are fixedly connected to the two ends of the bracket to form a closed space.

[0010] In a preferred embodiment, the bracket includes a fixed plate, a support plate, and a baffle. The fixed plate is fixedly connected to an elastic support piece, the support plate is connected to the fixed plate, the support plate is used to place cables, the baffle is connected to the support plate, and the two ends of the baffle are respectively connected to the fixed plate and the baffle.

[0011] In a preferred embodiment, the fixing device includes two brackets and a stop bar. The two brackets are fixed on both sides of the elastic support plate, and the two ends of the stop bar are fixedly connected to the two brackets respectively, forming a sealed space on the side of the elastic support plate.

[0012] In a preferred embodiment, one end of the stop bar is detachably connected to the bracket.

[0013] In a preferred embodiment, an L-shaped groove is formed at one end of the bracket, and the stop bar is fixed to the bottom end of the L-shaped groove using fasteners.

[0014] The multi-carriage cable support frame of this utility model has the following beneficial effects: This multi-carriage cable support frame for trains includes: elastic support plates and fixing devices. The elastic support plates are arc-shaped, and both ends of the elastic support plates are fixedly connected to two carriages respectively. The cables are supported on the sides of the elastic support plates by the fixing devices. The arc-shaped elastic support plates can adapt to the relative movement between the two carriages through deformation. By fixing the cables to the elastic support plates, contact between the cables and the folding canopy in the passage between the carriages is avoided, preventing cable wear and other damage. This solves the problem in existing technology where relative movement occurs between carriages when the train turns, causing relative movement between the cables and the folding canopy, leading to cable wear or displacement. In severe cases, the folding canopy may clamp the cables, pulling them and causing damage. Attached Figure Description

[0018] The multi-carriage cable support frame of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] like Figures 1-6As shown, this utility model discloses a multi-carriage cable support frame, including: an elastic support plate 1 and a fixing device 4. The elastic support plate 1 is arc-shaped, and its two ends are fixedly connected to two carriages respectively. The cable 3 is supported on the side of the elastic support plate by the fixing device 4. The elastic support plate 1 is made of a thin sheet of elastic material, cut into strips and bent into an arc shape. The two ends of the elastic support plate 1 are fixed above the two carriages respectively, so that the elastic support plate 1 is above the folding canopy and does not contact the folding canopy. Through the deformation of the elastic support plate 1, it can adapt to the relative movement between the two carriages. The fixing device 4 can be a cable tie, buckle, etc., which can support the cable 3 on the side of the elastic support plate 1. When supporting the cable 3, the cable 3 should not be pulled taut; to adapt to the relative movement between the two carriages, the cable should be in a slack state. By supporting the cable 3 on the side of the elastic support plate 1, the cable 3 is prevented from contacting the folding canopy of the passage between the carriages, thus preventing wear and damage to the cable 3. This solves the problem in the prior art where relative movement occurs between carriages when the train turns, causing relative movement between the cable 3 and the folding canopy, resulting in wear or displacement of the cable 3. In severe cases, the folding canopy may clamp the cable, thereby pulling on the cable and damaging it.

[0024] To ensure the elastic support plate 1 provides a more stable support for the cable 3, the multi-carriage cable support frame further includes a suspension device 5. The suspension device 5 comprises a roller 51 and a guide rod 52. The roller 51 is rotatably connected to the middle of the elastic support plate 1, and the guide rod 52 is fixedly connected to the folding canopy in the middle of the two carriages. The roller 51 is located at the upper end of the guide rod 52, and the roller 51 and guide rod 52 are in a rolling connection. This allows the guide rod 52 to suspend the middle of the elastic support plate 1 via the roller 51, providing a more stable support for the cable 3. Furthermore, the rolling connection between the roller 51 and guide rod 52 allows the roller 51 to roll along the guide rod 52 when the elastic support plate deforms due to the relative movement between the two carriages. This ensures that the suspension device supports the elastic support plate 1 while simultaneously adapting to its deformation.

[0025] To enable the roller 51 to move along the elastic support plate 1 and prevent the roller 51 from moving in a different direction from the guide rod 52 due to deformation of the elastic support plate 1, which could lead to the roller 51 detaching from the guide rod 52 or causing excessive force and wear between the roller 51 and the guide rod 52, the suspension device 5 further includes a roller frame 53. The roller 51 is rotatably connected to the roller frame 53, and the roller frame 53 is slidably connected to the elastic support plate 1. In this way, the roller frame 53 can slide along the elastic support plate 1 with the roller 51, thereby adapting to various deformations of the elastic support plate 1.

[0026] To allow the roller frame 53 to slide smoothly with the elastic support plate 1, a through groove 531 is provided in the roller frame 53, through which the elastic support plate 1 passes, allowing the roller frame 53 to slide on the outside of the elastic support plate 1. This structure is simple and can satisfy the small range of sliding of the roller frame 53 along the elastic support plate 1.

[0027] To facilitate the connection between the elastic support plate 1 and the carriage, the multi-carriage cable support frame also includes fixed brackets 2. The two ends of the elastic support plate 1 are fixedly connected to two carriages respectively via two fixed brackets 2. Figure 1 As shown, one end of the fixed bracket 2 is fixedly connected to the elastic support plate 1, and the other end of the fixed bracket 2 is fixedly connected to the carriage. The connection between the fixed bracket 2, the elastic support plate 1, and the carriage can be made using fasteners, such as bolts and nuts.

[0028] To ensure the cable is securely fixed by the fixing device 4, the number of fixing devices is 4-10. The fixing device 4 includes a bracket 41 and a stop bar 42. The bracket 41 is fixedly connected to the elastic support plate 1 using fasteners. Figure 2 As shown, the two ends of the stop bar 42 are fixedly connected to the two ends of the bracket 41, forming a closed space. The closed space formed between the stop bar 42 and the bracket 41 is used to accommodate the cable 3, preventing the cable 3 from falling off.

[0029] like Figure 5 and Figure 6 As shown, to ensure reliable support of the cable 3 by the bracket 41 and the stop bar 42, the bracket 41 includes a fixed plate 411, a support plate 412, and a baffle 413. The fixed plate 411 is fixedly connected to the elastic support piece 1, the support plate 412 is connected to the fixed plate 411, and the support plate is used to place the cable 3. The baffle 413 is connected to the support plate 412, and the two ends of the stop bar 42 are respectively connected to the fixed plate 411 and the baffle 413. The fixed plate 411, the support plate 412, and the baffle 413 can be integrally formed, or they can be made by cutting steel plates into strips and bending them to form the fixed plate 411, the support plate 412, and the baffle 413. Normally, the fixing plate 411 is fixedly connected to the elastic support plate 1, which can be connected by fasteners. At this time, the fixing plate 411 is in the vertical direction, the support plate 412 supports the cable 3 and should be in the horizontal direction, and the baffle 413 needs to block the cable 3 to prevent the cable 3 from falling off. Therefore, the baffle 413 can be perpendicular to the support plate or at a certain angle to the support plate.

[0030] In a preferred embodiment, such as Figure 3 As shown, the fixing device 4 includes two brackets 41 and a stop bar 42. The two brackets 41 are fixed to both sides of the elastic support plate 1, and the two ends of the stop bar 42 are fixedly connected to the two brackets 41 respectively, forming closed spaces on both sides of the elastic support plate 1. In this way, the cable 3 can be supported on both sides of the elastic support plate 1.

[0031] To facilitate the inspection or replacement of cable 3, one end of the stop bar 42 is detachably connected to the bracket 41, such as... Figure 5 As shown, when it is necessary to repair or replace cable 3, the cable needs to be removed from the enclosed space formed by bracket 41 and stop bar 42. At this time, it is only necessary to detach one end of stop bar 42 from bracket 41, and cable 3 can be removed by moving stop bar 42.

[0032] To facilitate the disassembly and installation of the stop lever 42 and the bracket 41, an L-shaped groove 414 is provided at one end of the bracket 41, such as... Figure 5 and Figure 6 As shown, fastener 43 is used to fix the stop bar 42 to the bottom end of the L-shaped groove 414. During disassembly, simply loosen the fastener 43 to remove the stop bar 42 from the L-shaped groove, allowing the cable 3 to be removed or placed. It is required that the diameter of the stop bar 42 is smaller than the diameter of the through hole 415 on the bracket 41 that mates with the stop bar 42. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
