Description

Technical Field

[0001] This utility model relates to the field of railway signal experiment simulation and demonstration, specifically a simulation and demonstration device for railway signal testing. Background Technology

[0002] Railway signaling is a technical means of controlling train intervals and ensuring train operation. Also known as railway signaling, its function is to ensure train operation safety, effectively improve railway transportation efficiency, reduce transportation costs, and greatly improve the working conditions of train operators. Therefore, railway signaling equipment is a key device for organizing and directing train operation, ensuring traffic safety, improving transportation efficiency, transmitting traffic information, and improving the working conditions of train operators. To facilitate railway signal simulation demonstration operations, a simulation demonstration device is needed. The "Simulation Demonstration Device for Railway Signal Testing" disclosed in application number "CN212698365U" is an example of such a device. While this technology is becoming increasingly mature, its "invention, through the setting of a display frame, a display base, and a lead screw, allows the lead screw to rotate by turning the rotating handle at the bottom of the base. The rotation of the lead screw moves the display frame upwards along the display base, thereby causing the signal light to extend from inside the display base, completing a simulated railway signal display. After the test, turning the rotating handle in the opposite direction moves the display frame and signal light downwards along the display base, retracting them back into the display base and sealing the signal light for dust protection, effectively improving the service life of the signal display device." However, this display device still has the following drawbacks during use:

[0003] The current display device, through the coordinated structure of the display frame, display base, and lead screw, does indeed achieve the effect of controlling the raising and lowering of the signal light. However, this structure only provides a raising and lowering effect and does not facilitate orientation adjustment as needed, thus affecting the practicality of the display device. Therefore, it is necessary to provide a display device that can both raise and lower and adjust the orientation. In addition, the current display device is inconvenient to adjust in position during use, and adjusting the position increases labor intensity. Therefore, it is necessary to provide a display device that facilitates automatic position adjustment, reduces labor intensity, and improves the convenience of adjustment. Utility Model Content

[0004] This utility model provides a simulated display device for railway signal testing, aiming to solve the problems of existing display devices being inconvenient for height and orientation adjustment, as well as position adjustment.

[0005] To achieve the above objectives, this utility model provides a simulation display device for railway signal testing, including a moving simulation display component and a lifting simulation display component;

[0006] The mobile simulation display component includes a base with two strip-shaped grooves at its upper end. A lead screw and a guide rod are respectively installed inside each of the two strip-shaped grooves. A first motor is installed at one end of the lead screw. A movable seat is slidably installed on the side surface of the lead screw and guide rod. A first gear is rotatably connected inside the movable seat. A second motor is installed at the upper end of the movable seat. A first bevel gear is installed at the output end of the second motor. A second bevel gear is fixedly installed at the upper end of the first gear. The first and second bevel gears mesh with each other. Two sliding rods are fixedly connected to the lower end of the movable seat. The lead screw and guide rod are both installed inside the sliding rods.

[0007] A lifting simulation display component includes a main board with a toothed groove on its surface. A second gear is meshed inside the toothed groove. A third motor is installed on one side of the second gear. The lower end of the main board is fixedly connected to the third gear. An indicator light is installed at the front end of the main board. The first gear and the third gear are meshed together.

[0008] As a preferred embodiment of this utility model, a sunshade assembly is installed on the upper end of the main board. The sunshade assembly includes two rods, and a sunshade plate is rotatably connected to the upper end of the two rods. An octagonal shaft is fixedly connected to the upper end of the two rods. Two hinge blocks are fixedly connected to the lower end of the sunshade plate. An octagonal hole is opened on the surface of each of the two hinge blocks, and the octagonal shaft is inserted into the octagonal hole.

[0009] As a preferred embodiment of this utility model, the upper end of the movable base is provided with a mounting groove, and the first gear and the third gear are rotatably connected inside the mounting groove.

[0010] As a preferred embodiment of this utility model, the upper end of the base is provided with a wheel groove, and the lower end of the movable seat is rotatably connected to two wheels, both of which are placed inside the wheel groove.

[0011] In a preferred embodiment of this utility model, the upper end of the motherboard has two sockets, the back of the signal light is fixedly connected to two clamps, the second gear is rotatably connected between the two clamps, and the plug is inserted into the socket.

[0012] As a preferred embodiment of this utility model, the surface of the motherboard has two guide grooves, and the front ends of the two clamping plates are fixedly connected to guide blocks, which are slidably connected inside the guide grooves.

[0013] As a preferred embodiment of this utility model, the surface of the signal light is fitted with a protective shell, which is made of transparent plastic.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When adjusting the height of the signal light, the third motor is first started to rotate the third gear clockwise or counterclockwise. At this time, the third gear is engaged in the tooth groove, which can control the third gear to raise and lower the signal light along the tooth groove, thus adjusting the height of the signal light. Then, the second motor is started to rotate the first bevel gear, which in turn rotates the second bevel gear and the first gear at its lower end. Since the first gear and the third gear are engaged, the main board and the signal light on its surface can rotate 360°. Compared with the display device in the existing technology "A Simulation Display Device for Railway Signal Test", this utility model, through the above-mentioned structure, can facilitate the adjustment of the height and orientation of the signal light, thereby enhancing the practicality of the display device.

[0016] 2. When simulating the adjustment of the signal light position, the first motor is started to rotate the lead screw clockwise or counterclockwise. With the help of the guide rod, the two sliding rods can be controlled to move back and forth along the strip groove. Therefore, the moving seat can be controlled to move the upper main board and the signal light along the base. At the same time, the wheels move along the wheel groove, thereby adjusting the height of the main board. Compared with the display device in the existing technology "A Simulation Display Device for Railway Signal Test", this utility model can facilitate the adjustment of the main board position through the above-mentioned structure, improving the ease of use of the display device.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a simulation display device for railway signal testing, including a movable simulation display component 100 and a lifting simulation display component 200;

[0024] The mobile simulation display component 100 includes a base 101. Two strip-shaped grooves 102 are formed at the upper end of the base 101. A lead screw 103 and a guide rod 105 are respectively installed inside each of the two grooves 102. A first motor 104 is installed at one end of the lead screw 103. A movable seat 106 is slidably mounted on the side surfaces of the lead screw 103 and guide rod 105. A first gear 107 is rotatably connected inside the movable seat 106. A second motor 108 is installed at the upper end of the movable seat 106. A first bevel gear 109 is installed at the output end of the second motor 108. A second bevel gear 110 is fixedly installed at the upper end of the first gear 107. The first bevel gear 109 and the second bevel gear 110 are meshed together. Two sliding rods 120 are fixedly connected to the lower end of the movable seat 106. The lead screw 103 and the guide rod 105 are both installed inside the sliding rods 120.

[0025] The lifting simulation display component 200 includes a main board 201. The surface of the main board 201 has a toothed groove 202. A second gear 203 is meshed inside the toothed groove 202. A third motor 204 is installed on one side of the second gear 203. A third gear 205 is fixedly connected to the lower end of the main board 201. A signal light 206 is installed at the front end of the main board 201. A first gear 107 and a third gear 205 are meshed together.

[0026] In one specific embodiment, the movable simulation display component 100, in conjunction with the lifting simulation display component 200, facilitates both the adjustment of the height and orientation of the signal light 206, thereby enhancing the practicality of the display device. Furthermore, the coordinated structure allows for automatic control of the signal light 206's position adjustment as needed, improving the ease of use of the display device. In use, the first motor 104 is started, causing the lead screw 103 to rotate clockwise or counterclockwise. This, along with the guide rod 105, controls the two sliding rods 120 to reciprocate along the strip groove 102, thereby controlling the movable base 106 to move the main board 201 and the signal light 206 on the base 101. To facilitate the adjustment of the display device's position, the third motor 204 is then activated, causing the third gear 205 to rotate clockwise or counterclockwise. The third gear 205 meshes with the tooth groove 202, controlling the third gear 205 to move the signal light 206 up and down along the tooth groove 202, thus allowing adjustment of the signal light 206's height. Next, the second motor 108 is activated, causing the first bevel gear 109 to rotate, which in turn rotates the second bevel gear 110 and its lower end, the first gear 107. At this time, the first gear 107 and the third gear 205 mesh, allowing the main board 201 and its surface signal light 206 to rotate 360° in all directions, thereby adjusting the height and orientation of the signal light 206 to enhance the practicality of the display device.

[0027] Please see Figure 4 The upper end of the main board 201 is equipped with a sunshade assembly 300. The sunshade assembly 300 includes two insert rods 301. The upper ends of the two insert rods 301 are rotatably connected to a sunshade plate 302. The upper ends of the two insert rods 301 are fixedly connected to an octagonal shaft 303. The lower end of the sunshade plate 302 is fixedly connected to two hinge blocks 304. The surfaces of the two hinge blocks 304 are provided with octagonal holes 305. The octagonal shaft 303 is inserted into the octagonal hole 305.

[0028] In one specific embodiment, by controlling the octagonal shaft 303 to rotate around the octagonal hole 305, the height of the sunshade 302 can be adjusted. By blocking sunlight with the sunshade 302, the signal light 206 can be kept bright for easy observation.

[0029] Please see Figure 2 and Figure 3 The upper end of the movable base 106 is provided with a mounting groove 111, and the first gear 107 and the third gear 205 are rotatably connected inside the mounting groove 111.

[0030] In one specific embodiment, the mounting groove 111 facilitates the rotational connection between the first gear 107 and the third gear 205, thereby improving the connection stability between the two gears and the base 101.

[0031] Please see Figure 2 The upper end of the base 101 is provided with a wheel groove 121, and the lower end of the movable seat 106 is rotatably connected to two wheels 122, both of which are placed inside the wheel groove 121.

[0032] In one specific embodiment, as the base 101 moves, the wheels 122 can be controlled to reciprocate along the wheel grooves 121, thereby improving the smoothness and stability of the moving seat 106 as it moves along the base 101.

[0033] Please see Figure 3 The motherboard 201 has two sockets 211 on its upper end. The back of the indicator light 206 is fixedly connected to two clamps 212. The second gear 203 is rotatably connected between the two clamps 212. The plug rod 301 is inserted into the inside of the socket 211.

[0034] In one specific embodiment, the insertion rod 301 is inserted into the socket 211, which can improve the ease of disassembly and assembly between the sun visor 302 and the main board 201. The clamp 212 facilitates the rotational connection of the second gear 203, so as to improve the lifting stability of the signal light 206.

[0035] Please see Figure 3 The motherboard 201 has two guide grooves 221 on its surface. The front ends of the two clamping plates 212 are fixedly connected to guide blocks 222, which are slidably connected inside the guide grooves 221.

[0036] In one specific embodiment, when the signal light 206 moves up and down along the main board 201, the guide block 222 moves up and down along the guide groove 221, which can limit the clamping plate 212, thereby further improving the stability of the signal light 206.

[0037] Please see Figure 3 The surface of the signal light 206 is covered with a protective shell 231, which is made of transparent plastic.

[0038] In one specific embodiment, the protective shell 231 made of transparent plastic can protect the signal light 206 and prevent foreign objects from damaging the signal light 206.

[0039] Working principle: In use, the first motor 104 is started, driving the lead screw 103 to rotate clockwise or counterclockwise. This, in conjunction with the guide rod 105, controls the two sliding rods 120 to reciprocate along the strip groove 102. This controls the movement of the movable seat 106, carrying the main board 201 and the indicator light 206, on the base 101, thereby adjusting the position of the display device. Next, the third motor 204 is started, driving the third gear 205 to rotate clockwise or counterclockwise. The third gear 205 meshes with the tooth groove 202, thereby controlling the third... Gear 205 moves the signal light 206 up and down along the tooth groove 202, thereby adjusting the height of the signal light 206. At this time, the second motor 108 is started, which rotates the first bevel gear 109, thus rotating the second bevel gear 110 and its lower first gear 107. The first gear 107 and the third gear 205 mesh and connect, thereby rotating the main board 201 and the signal light 206 on its surface 360° in all directions, so as to adjust the height and orientation of the signal light 206, thereby enhancing the practicality of the display device.
