Description

Technical Field

[0001] The utility model relates to the technical field of railway transportation, especially to a display device for railway operation organization and dispatching. Background Art

[0002] Railway operation organization and dispatching is the core command mechanism of railway transportation, ensuring safety and efficiency through centralized planning and coordinating train operations. As its "nerve center", the tiled display screen integrates multi-source information, enhances situation awareness and optimizes decision-making, supporting the intelligent dispatching visualization platform.

[0003] Currently, a Chinese patent discloses a tiled liquid crystal display screen (the authorization announcement number is CN223004692U). Hooks for hanging on the mounting rod are provided at the four corners on the rear side of each display screen body. A C-shaped groove for accommodating the mounting rod is opened at the bottom of each hook, and an anti-slip pad for anti-slip is covered in the C-shaped groove. The display screen body is hung on the corresponding rod-shaped support rod through the C-shaped groove on the hook, thereby completing the splicing of the display screen body. The anti-slip pad can prevent the hook from displacing on the rod-shaped support member.

[0004] Since the above device uses the method of a bracket cooperating with a hook to lock the tiled display screen, however, the low-frequency vibration when the train passes by will be transmitted to the bracket through the wall, and long-term action may cause the hook to displace, resulting in adjacent screens squeezing and colliding with each other, and there is a hidden danger of damage. Summary of the Utility Model

[0005] Based on this, in view of the problem that the tiled display screen installed by the hook method is prone to looseness and there is squeezing and collision, it is necessary to provide a display device for railway operation organization and dispatching.

[0006] The display device for railway operation organization and dispatching includes:

[0007] Tiled display screens evenly distributed, and two adjacent display screens are aligned;

[0008] Positioning tubes evenly distributed, the vertical cross-sectional shape of the positioning tube is "卄"-shaped, and a positioning ring groove is opened on the surface of the positioning tube;

[0009] Locking mechanisms evenly distributed, the locking mechanism includes a positioning member, the positioning member is clamped inside the positioning ring groove, the vertical cross-sectional shape of the positioning member is "h"-shaped, a through hole is opened on the surface of the positioning member, a threaded column fixedly connected to the display screen is inserted inside the through hole, and a nut is threadedly connected to the surface of the threaded column.

[0010] In one embodiment, the widths of the positioning ring groove and the positioning member are the same, and the numerical ratio of the depth of the positioning ring groove to the thickness of the positioning member is 1:2.

[0011] In one embodiment, the positioning member has an inner groove for mounting, and a resistance-increasing strip that contacts the positioning ring groove is embedded inside the mounting groove.

[0012] In one embodiment, the number of mounting slots and resistance bars is the same and not less than five, and the mounting slots and resistance bars are distributed in an arc shape around the center line of the positioning ring slot.

[0013] In one embodiment, the number of the perforation, threaded post, and nut are all two and symmetrically distributed on both sides of the center point of the positioning element.

[0014] In one embodiment, a connector is inserted between two adjacent positioning tubes, and the connector is a stainless steel component.

[0015] In one embodiment, the vertical cross-sectional shape of the connector is "+", and the maximum diameter of the connector located outside the positioning tube is greater than the inner diameter of the positioning tube.

[0016] In one embodiment, the surface of the positioning tube is fixedly connected to a uniformly distributed stainless steel mounting frame, and two expansion bolts are inserted into the surface of the stainless steel mounting frame.

[0017] Beneficial effects

[0018] 1. In the aforementioned railway traffic organization and scheduling display device, the positioning ring groove forms a three-dimensional spatial fit with the "h"-shaped positioning component through its groove. When the positioning component is engaged in the ring groove, the sidewall of the ring groove generates a radial constraint force on the positioning component, blocking the horizontal sliding path. This structure converts vibration energy into contact surface friction dissipation, effectively suppressing the risk of collision between adjacent screens.

[0019] 2. Multiple sets of resistance-increasing strips are arranged in an arc array along the axis of the positioning ring groove. Their high friction coefficient material forms multi-point contact damping with the inner wall of the ring groove. During vibration transmission, the resistance-increasing strips absorb kinetic energy through elastic deformation, significantly reducing vibration transmission efficiency and ensuring stable connection between the positioning component and the ring groove.

Detailed implementation manners

[0028] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0029] The following combines Figure 1 - Figure 5 to describe the railway train operation organization dispatching display device of the present utility model.

[0030] In one embodiment, the railway train operation organization dispatching display device includes:

[0031] The display screens 100 are evenly distributed, and two adjacent display screens 100 are aligned. The evenly distributed and aligned design ensures the continuity of information display and the consistency of visibility;

[0032] The positioning tubes 200 are evenly distributed. The vertical cross-sectional shape of the positioning tube 200 is "卄"-shaped, and a positioning ring groove 210 is formed on the surface of the positioning tube 200;

[0033] The locking mechanism 300 is evenly distributed. The locking mechanism 300 includes a positioning member 310. The positioning member 310 is snapped into the inside of the positioning ring groove 210. The vertical cross-sectional shape of the positioning member 310 is "h". The surface of the positioning member 310 is provided with a through hole 311. A threaded post 320 that is fixedly connected to the display screen 100 is inserted into the inside of the through hole 311. A nut 330 is threadedly connected to the surface of the threaded post 320.

[0034] When the positioning member 310 is inserted into the positioning ring groove 210, the positioning ring groove 210 can effectively prevent the positioning member 310 from sliding horizontally along the surface of the positioning tube 200. This can ensure that the display screen 100 runs more stably on the positioning tube 200 and effectively reduce the probability of two adjacent display screens 100 being squeezed or collided with each other due to external force vibration.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the positioning ring groove 210 and the positioning element 310 have the same width, and the ratio of the depth of the positioning ring groove 210 to the thickness of the positioning element 310 is 1:2. An installation groove 312 is provided on the inner side of the positioning element 310, and a resistance-increasing strip 340 that contacts the positioning ring groove 210 is embedded inside the installation groove 312. The number of installation grooves 312 and resistance-increasing strips 340 is the same and not less than five. The installation grooves 312 and resistance-increasing strips 340 are arranged in an arc shape around the axis of the positioning ring groove 210, and multiple sets of resistance-increasing strips 340 are arranged in an arc array along the axis of the positioning ring groove 210. Their high-friction coefficient material forms multi-point contact damping with the inner wall of the ring groove. During vibration transmission, the resistance-increasing strips 340 absorb kinetic energy through elastic deformation, significantly reducing vibration transmission efficiency and ensuring a stable connection between the positioning element 310 and the ring groove. The number of through holes 311, threaded posts 320, and nuts 330 are two each and symmetrically distributed on both sides of the center point of the positioning element 310.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connector 400 is inserted between two adjacent positioning tubes 200. The connector 400 is a stainless steel component. The vertical cross-section of the connector 400 is "+" shaped. The maximum diameter of the connector 400 outside the positioning tube 200 is greater than the inner diameter of the positioning tube 200. The "+" shaped cross-section is inserted into the positioning tube 200. The diameter difference design prevents it from falling off. The stainless steel material improves durability. The surface of the positioning tube 200 is fixedly connected with evenly distributed stainless steel mounting frames 500. Two expansion bolts 600 are inserted into the surface of the stainless steel mounting frames 500. The evenly distributed stainless steel mounting frames 500 and the double expansion bolts 600 achieve a firm fixation to the wall.

[0037] Installation process of railway traffic organization and dispatching display device:

[0038] Basic fixing stage: Use expansion bolts 600 to fix the stainless steel mounting frame 500 and the connected positioning tube 200 to the wall; insert the connector 400 into the side opening of the positioning tube 200; horizontally insert another positioning tube 200 to the exposed end of the connector 400; repeat the above steps until all positioning tubes 200 are firmly locked.

[0039] Display screen 100 is connected to the LKJ system: the display screen 100 is connected to the central processing unit of the LKJ system via a cable or network interface; the display screen 100 receives train operation data as a terminal.

[0040] Locking the display screen 100: First, fix the threaded post 320 on the back of the display screen 100; after passing the threaded post 320 through the through hole 311, tighten the nut 330 symmetrically; so that the positioning part 310 is firmly locked on the back of the display screen 100; hang the positioning part 310 into the positioning ring groove 210 and ensure that all hooks are firmly attached.

[0041] The operation process of the railway traffic organization and scheduling display device is as follows: the display screen 100 receives data such as train speed and speed limit ahead transmitted from the LKJ system in real time, and displays the received data on the screen of the display screen 100.

[0042] It should be noted that the LKJ system is the core device of China's train operation monitoring system, primarily used for train safety control on non-high-speed railways. Its core functions include real-time monitoring of train speed, preventing speeding and overtaking signals, recording operational data, and assisting drivers. The LKJ system calculates and displays the current maximum permissible safe speed by combining onboard equipment with track data, and automatically applies braking when necessary to ensure operational safety. As a key carrier of human-machine interaction, the display screen 100 is closely linked to the LKJ system, responsible for displaying operational parameters in real time and providing an operating interface. The display screen 100 communicates with the LKJ host via a bus, supporting multi-area block display and dynamic warning functions, ensuring that drivers can clearly obtain key information and respond accordingly. Furthermore, some train models employ a redundant design, using a dual-screen configuration to ensure system reliability. Overall, the LKJ system and the display screen 100 together constitute an important part of the train operation safety protection system; the former is responsible for data processing and safety control, while the latter realizes information visualization and interaction. Together, they ensure the efficiency and safety of railway transportation.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features.
