Description

Technical Field

[0001] This application belongs to the field of rail vehicle interior technology, and particularly relates to a quick-opening tooling for the side roof panel of a rail vehicle. Background Technology

[0002] The side roof panels of rail vehicles generally serve to conceal door controllers, door mechanisms, and other equipment to maintain the aesthetics and tidiness of the interior, and to provide a mounting base for electrical components such as speakers and dynamic maps. During vehicle maintenance, these equipment and electrical components are mandatory inspection items; therefore, all side roof panels need to be opened or removed to facilitate maintenance. Each rail vehicle typically has 18 or more side roof panels. To ensure efficiency and safety during maintenance, the side roof panel structure should be designed to allow for quick opening and possess high safety and stability.

[0003] Existing rail vehicle side roof panels typically employ the following two fixing methods, which present the following problems: The first method uses bolt fixing, where the upper part (near the roof arc) and the lower part (near the side wall or door panel) of the side roof are both bolted. The side roof is generally about 2m long, with 6-8 connection points at the top and 3-4 connection points at the bottom. There are 18 or more side roofs in the whole vehicle, and the number of bolts connecting each side roof is at least 170.

[0004] The drawback of this solution is: When inspecting equipment or electrical components inside the side top plate, all bolts need to be removed to completely remove the side top plate. This operation is cumbersome, time-consuming, and inefficient. Furthermore, repeated disassembly and reassembly can easily damage the threads or the top plate.

[0005] The second method is to use an upper arc-shaped rotating hook structure and a lower bolt fixing method. That is, the upper part of the side top plate is connected by a continuous hook structure, and the lower part is fixed to the side wall panel or door cover panel flange by bolts.

[0006] The drawback of this solution is: ① Poor stability and safety hazards: The side top panel only uses a simple arc-shaped interlocking rotating hook structure at the top to achieve rotational opening, while the bolts at the bottom still need to be removed. In the open state, the entire weight of the side top panel is supported and its position is maintained solely by the free suspension structure at the top. This structure is prone to swaying and accidental slippage when accidentally touched by personnel, posing a significant safety hazard of injuring people. ② Risk of jamming or misalignment: The existing arc-shaped interlocking rotating hook is a continuous structure. When slight deformation occurs in the contact surface (such as thermal expansion and contraction, stress deformation), the stress can easily cause the entire rotating mechanism to jam, making it difficult to open or close smoothly, or causing unacceptable misalignment between adjacent side top plates after closing. ③ Inconvenient operation: After opening, the side top plate is suspended in the air and lacks effective support. Maintenance personnel need to be extra careful when operating, or they need to remove the side top plate from the hook, which affects work efficiency. Utility Model Content

[0007] In view of this, this application aims to provide a quick-opening tooling for the side top plate of a rail vehicle to solve at least one of the above-mentioned problems.

[0008] To achieve the above objectives, the technical solution of this application is implemented as follows: This application provides a quick-opening fixture for the side top plate of a rail vehicle, including a mounting base, a side top plate, a locking component, and an adjustable support structure; The top of the mounting base is fixedly connected to the roof frame, and its bottom end is rotated with one end of the side roof panel through an anti-slip bracket. Multiple locking components are spaced apart on the side top plate, and the locking tongues of the locking components press against the flange of the side wall plate or door cover plate. The adjustable support structure is provided in two sets, which are symmetrically arranged on both sides of the top plate. Each adjustable support structure includes a connector, a locking component, and a support rod. The connector and the locking component are slidably disposed on the top plate and are fixed in position by fasteners. One end of the support rod is disposed on the connector, and the other end is detachably connected to a hook. The hook is used to hang in the reserved hole of the side wall panel or door panel. The locking component is used to lock the support rod after it is retracted.

[0009] Furthermore, the mounting base is fixed to the roof frame by evenly distributed bolts, and the bottom end of the mounting base is provided with a full-length arc hook; The side top plate includes an integrally formed horizontal cover plate and a vertical cover plate. The vertical cover plate is inclined to the horizontal cover plate. A bending part is provided on the inner wall of the top of the vertical cover plate. The bending part is hung in the arc hook. The outer diameter of the arc of the bending part matches the inner diameter of the arc groove formed on the arc hook.

[0010] Furthermore, the bent portion is provided with several clearance notches; The anti-slip bracket includes a fixing part and a shaft. The fixing part is fixed to the outer wall of the mounting base and is correspondingly disposed at the clearance notch. The shaft is rotatably connected to the fixing part and is located inside the bending part.

[0011] Furthermore, the outer diameter of the shaft matches the inner diameter of the arc of the bend.

[0012] Furthermore, the transverse cover plate is provided with a slide rail; The connector includes a fixing plate and a hook ring disposed on the fixing plate. The fixing plate is slidably disposed on the slide rail by fasteners connected thereto.

[0013] Furthermore, the locking component includes a support plate and a fixing clip. The support plate is slidably mounted on the slide rail by fasteners connected thereto. The fixing clip is detachably mounted on the top of the support plate and is used to lock the retracted support rod.

[0014] Furthermore, the support rod is threadedly connected to the hook at its front end.

[0015] Compared with the prior art, the quick-opening tooling for the side roof of a rail vehicle described in this application has the following advantages: (1) Significantly improved maintenance efficiency: The rotating structure formed between the mounting base and the side top plate and the locking connection form make the maintenance operation simple and fast (opening the fixation only takes a few seconds to tens of seconds), without the need to disassemble any bolts, avoiding the tedious work of repeatedly disassembling and assembling bolts and potential damage, and significantly saving maintenance time.

[0016] (2) Easy to open: After unlocking the lower tightening lock, simply pull outward and rotate the side top plate downward. The whole process is smooth.

[0017] (3) Improved safety performance: The anti-slip brackets provide key rotational support points, effectively preventing the side top plate from slipping and moving laterally; The addition of a break-off notch design to the side top plate hook greatly improves the fault tolerance of the rotating mechanism and avoids major problems (jamming, misalignment) caused by small deformations. The adjustable support rods provide a stable triangular support system, completely eliminating the risk of overturning and ensuring that the side top plate is rock-solid when open, thus protecting the safety of maintenance personnel.

[0018] (4) Excellent stability: The anti-slip bracket and support rod work together to ensure that the open side top plate remains stable under various working conditions (vibration, slight collision), providing a safe, reliable and spacious space for maintenance operations.

[0023] Please see Figures 1 to 5 As shown, this embodiment provides a quick-opening fixture for the side top plate of a rail vehicle, including a mounting base 1, a side top plate 2, a locking component 4, and an adjustable support structure 5; Among them, the top of the mounting base 1 is fixedly connected to the roof frame, and its bottom end is rotated with one end of the side roof plate 2 through the anti-slip bracket 3; Multiple locking components 4 are spaced apart on the side top plate 2, and the locking tongue of the locking component 4 (the locking component 4 described in this embodiment is a tension lock) presses against the flange of the side wall plate or door cover plate. Two sets of adjustable support structures 5 are provided, and the two sets of adjustable support structures 5 are symmetrically arranged at the two side edges of the side top plate 2. Each adjustable support structure 5 includes a connector 51, a locking member 52 and a support rod 53. The connector 51 and the locking member 52 are slidably arranged on the side top plate 2 and are fixed in position by fasteners 513. One end of the support rod 53 is arranged on the connector 51, and the other end is detachably connected to a hook. The hook is used to hang in the reserved hole of the side wall plate or the vertical cover plate. The locking member 52 is used to lock the support rod 53 after it is retracted.

[0024] Specifically, in this embodiment, the fixture includes a mounting base 1, a side top plate 2, four anti-slip brackets 3, three locking components 4, and two adjustable support structures 5. The mounting base 1 is connected to the roof frame by fasteners; the side top plate 2 is hung in the circular hook groove of the mounting base 1 by a rotating structure; the anti-slip brackets 3 are connected to the side facade of the mounting base 1 by fasteners, and the installation position matches the clearance notch 24 of the arc hook 11 of the side top plate 2; the locking components 4 are installed at the lower part of the side top plate 2, and when in the locked state, the locking tongue presses against the flange of the side wall panel or door panel to ensure that it is in a taut state; the adjustable support structures 5 are connected to the side top plate 2 by fasteners, and when the side top plate 2 is in the locked state, the support rod 53 is retracted and fixed in the locking component 52.

[0025] The locking component 4 is located at the lower part of the side top plate 2. This component is a tension lock structure. During maintenance, the connection between the lower part of the side top plate 2 and the side wall or door panel can be quickly opened by simply unscrewing the tension lock without disassembling any bolts. When the tension lock is locked, it can provide a reliable fastening force.

[0026] The tooling described in this embodiment uses a rotating structure formed between the mounting base 1 and the side top plate 2, and a locking component 4 for connection, making maintenance operations simple and quick (opening and fixing only takes a few seconds to tens of seconds), without the need to remove any bolts, avoiding the tedious work of repeatedly disassembling and assembling bolts and potential damage, and significantly saving maintenance time; at the same time, the rotating structure, anti-slip bracket 3 and adjustable support structure 5 together form an extremely stable triangular support system, completely eliminating the risk of overturning, ensuring the stability of the side top plate 2 in the open state, and ensuring the safety of maintenance personnel.

[0027] In some implementations, such as Figure 4 As shown, the mounting base 1 is fixed to the roof frame by evenly distributed bolts, and the bottom end of the mounting base 1 is provided with a full-length arc hook 11. The side top plate 2 includes an integrally formed horizontal cover plate 21 and a vertical cover plate 22. The vertical cover plate 22 is inclined to the horizontal cover plate 21. A bending part 23 is provided on the inner wall of the top of the vertical cover plate 22. The bending part 23 is hung in the arc hook 11. The outer diameter of the arc of the bending part 23 matches the inner diameter of the arc groove formed on the arc hook 11. Several clearance notches 24 are provided on the bending part 23; like Figure 3 As shown, the anti-slip bracket 3 includes a fixing part 31 and a shaft 32. The fixing part 31 is fixed on the outer wall of the mounting base 1 and is correspondingly provided at the clearance notch 24. The shaft 32 is rotatably connected to the fixing part 31 and is located inside the bending part 23. The outer diameter of the shaft 32 matches the inner arc diameter of the bending part 23.

[0028] Specifically, in this embodiment, such as Figure 2 As shown, the mounting base 1 is set on the upper part of the side roof plate 2 and is a fixed component. It is fixed to the roof frame by evenly distributed bolts. The material is aluminum profile, which has sufficient strength. The lower part is provided with a full-length arc hook 11 to facilitate the suspension and rotation of the side roof plate 2. The hook height of the arc hook 11 should be sufficient to ensure that the side roof plate 2 does not fall out when opened to the ideal maintenance angle under the condition that it is not subjected to external force.

[0029] The side top plate 2 includes a horizontal cover plate 21 and a vertical cover plate 22 inclinedly arranged on the horizontal cover plate 21, both made of cold-pressed and bent aluminum sheet. The upper part is designed with a bent structure, which hangs in the arc groove formed by the arc hook 11 on the mounting base 1. The outer diameter of the arc of the hook matches the inner diameter of the arc groove of the mounting base 1, ensuring smooth rotation of the side top plate 2. The arc hook 11 has a clearance notch 24 at an appropriate position that matches the anti-slip bracket 3. When a slight deformation occurs at a local contact point of the arc rotating hook structure, a certain amount of stress can be released, thus ensuring that this local deformation does not cause the entire rotating engagement mechanism to jam, allowing it to still rotate smoothly.

[0030] The anti-slip bracket 3 is fixed to the vertical surface of the mounting base 1 by bolts. The installation position matches the position of the clearance notch 24 of the side top plate 2. First, it restricts the lateral displacement of the side top plate 2 in the arc groove. Second, the cylindrical shaft 32 is inserted into the arc groove of the side top plate 2. During the process of rotating the side top plate 2 to the maximum opening for maintenance, it can press the inner arc surface of the rotating side top plate 2 to prevent the side top plate 2 from falling out. The outer diameter of the shaft 32 matches the inner arc diameter of the hook of the side top plate 2, which can both prevent the side top plate 2 from falling out and ensure the smooth rotation of the side top plate 2.

[0031] In some embodiments, a slide rail 25 is provided on the transverse cover plate 21 (a C-shaped groove is formed in the slide rail 25). The connector 51 includes a fixing plate 511 and a hook ring 512 disposed on the fixing plate 511. The fixing plate 511 is slidably disposed on the slide rail 25 by fasteners 55 connected thereon. The locking component 52 includes a support plate 521 and a fixing clip 22. The support plate 521 is slidably mounted on the slide rail 25 by fasteners 55 connected thereon. The fixing clip 22 is detachably mounted on the top of the support plate 521. The fixing clip 22 is used to lock the stored support rod 53. The support rod 53 is threadedly connected to the hook 54 at its front end.

[0032] Specifically, in this embodiment, such as Figure 4 As shown, the support plate 521 and the fixing plate 511 are connected to the C-shaped groove on the back of the side top plate 2 by fastening (in this embodiment, the fastener is a slider with bolts, the slider is located in the groove, and the position is fixed by the cooperation of nuts, washers and gaskets on the bolts) 55. Each side top plate 2 has a support rod 53 at a distance of about 50mm from the edge on both sides. The hook at the front end of the support rod 53 is connected to the main rod by internal and external threads, and the length of the support rod 53 can be adjusted according to the maintenance space requirements. When the side top plate 2 is rotated to the maximum angle, the hook of the support rod 53 is hung at the reserved hole of the side wall plate or the vertical cover plate. Together with the rotating hook and the anti-slip bracket 3, it forms an extremely stable triangular support system, further preventing any accidental movement or shaking of the side top plate 2 during maintenance and ensuring absolute stability of operation. When the side top plate 2 is closed, the support rod 53 is screwed back into the fixing clip 22 for fixation.

[0033] like Figure 6 As shown, when the locking mechanism is unlocked, the lower part of the side top plate 2 is rotated downwards. When it reaches the maximum maintenance space angle, the support rod 53 is removed from the fixing clip 22 and rotated to fix the hook 54 at the front end of the support rod 53 into the pre-drilled small hole in the upper flange of the side wall plate or door cover plate, which provides stable support.

[0034] It should be noted that, as Figure 5 As shown, in this embodiment, an adjusting screw 6 is also installed on the side wall panel or door panel near the tension lock. The adjusting screw 6 has a rubber head. The purpose of setting the adjusting screw 6 is to adjust its height to match the locking stroke of the tension lock, so as to ensure that the tension lock is tightened when locked, which can prevent the vehicle from shaking and making abnormal noises during operation.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
