Description

Technical Field

[0001] This utility model relates to the field of high-speed train technology, and in particular to a stepping board for high-speed trains. Background Technology

[0002] With the rapid development of high-speed rail technology, high-speed trains have become an important part of modern transportation. During the operation of high-speed trains, passengers need to move frequently between carriages and platforms. Therefore, the design of the treadmill is crucial. The treadmill is a key component connecting carriages and platforms. Its main function is to provide passengers with a safe and stable transition platform to ensure that passengers can smoothly and safely enter and exit the carriages.

[0003] Traditional treads typically use relatively simple fixing methods, such as bolt connections. While these methods can achieve the basic fixing function of treads to a certain extent, bolt connections require pre-drilling holes in the treads and mounting components and tightening with nuts. This type of connection requires the use of tools such as wrenches during installation and disassembly, making the operation cumbersome and time-consuming. This not only increases maintenance costs but may also lead to longer train downtime, affecting the operational efficiency of high-speed trains. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a stepping board for high-speed trains.

[0005] This utility model is achieved using the following technical solution: a step for high-speed trains, comprising a step body, an embedded block fixedly connected to the surface of the step body, a mounting seat snapped onto the surface of the embedded block, a limiting seat fixedly connected to the inner wall of the mounting seat, a positioning cavity formed inside the limiting seat, a storage seat fixedly connected to the surface of the mounting seat, a telescopic spring fixedly connected to the inner wall of the storage seat, a movable plate fixedly connected to the surface of the telescopic spring, a horizontal insert rod fixedly connected to the surface of the movable plate, a pull block fixedly connected to the surface of the movable plate, a vertical insert rod provided inside the mounting seat, and a limit ring fixedly connected to the surface of the vertical insert rod.

[0006] The above technical solution uses a horizontal insert rod to lock the embedded block, and a vertical insert rod to lock the horizontal insert rod, achieving double locking. This ensures the stability of the tread plate body after installation inside the mounting base, enabling it to work stably and facilitating personnel movement between the carriage and the platform. This quick installation design improves the installation efficiency of personnel, and the tread plate body can be quickly disassembled when not in use. When it is damaged and needs to be replaced, it is also easy for personnel to quickly replace it, reducing maintenance time.

[0007] As a further improvement to the above solution, the embedded plug is inserted into the interior of the positioning cavity, and the transverse plug passes through the interior of the embedded plug.

[0008] As a further improvement to the above solution, a positioning hole is provided on the surface of the vertical insertion rod, and the vertical insertion rod is inserted into the positioning hole.

[0009] As a further improvement to the above solution, the surface of the embedded plug is provided with a limiting hole, which is adapted to the transverse plug rod.

[0010] As a further improvement to the above solution, opening slots are provided on both sides of the outer surface of the mounting base, and the opening slots are adapted to the embedded plug.

[0011] As a further improvement to the above solution, two embedded blocks are provided, and the two embedded blocks are respectively fixedly connected to both sides of the outer surface of the tread plate body.

[0012] As a further improvement to the above solution, the surface of the mounting base is provided with a sliding hole that matches the vertical insertion rod, and the vertical insertion rod is slidably connected to the surface of the mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs a dual locking mechanism of vertical and horizontal inserts. The horizontal insert penetrates the limiting hole of the insert block to achieve initial locking, while the vertical insert, under gravity, inserts into the horizontal insert to further secure the tread plate body. This enhances the stability of the tread plate after installation, preventing potential loosening or detachment risks and ensuring safe movement of personnel from the carriage to the platform. When disassembly is required, the tread plate body can be unlocked and removed simply by operating the vertical insert and the pull block, without the need for complex tools or cumbersome procedures. It allows for convenient separation and storage when not in use and enables rapid replacement when the tread plate body is damaged, reducing train downtime and improving the operational efficiency of high-speed trains.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example: Please combine Figure 1-5 This embodiment of a high-speed train treadmill includes a treadmill body 1. An embedded block 2 is fixedly connected to the surface of the treadmill body 1. A mounting base 3 is snapped onto the surface of the embedded block 2. A limiting seat 4 is fixedly connected to the inner wall of the mounting base 3. A positioning cavity 5 is formed inside the limiting seat 4. A storage seat 6 is fixedly connected to the surface of the mounting base 3. A telescopic spring 7 is fixedly connected to the inner wall of the storage seat 6. A movable plate 8 is fixedly connected to the surface of the telescopic spring 7. A horizontal insert rod 9 is fixedly connected to the surface of the movable plate 8. A pull block 10 is fixedly connected to the surface of the movable plate 8. A vertical insert rod 11 is provided inside the mounting base 3. A limit ring 12 is fixedly connected to the surface of the vertical insert rod 11. Personnel need to quickly assemble and disassemble the treadmill body 1 and the mounting base 3. In the initial state, the vertical insert rod 11 descends under gravity and inserts into the horizontal insert rod 9, locking the position of the horizontal insert rod 9. At this time, the telescopic spring 7 is not compressed, and the horizontal insert rod 9 is naturally inside the mounting base 3. During assembly, personnel first pull the vertical insert rod 11 upwards. To disengage it from the horizontal insert 9, unlock the horizontal insert 9. When the limiting ring 12 contacts the inner top wall of the mounting base 3, the vertical insert 11 stops rising to prevent excessive rising and disengagement from the mounting base 3. Next, the operator pulls the pull block 10 to retract the movable plate 8, causing the horizontal insert 9 to retract and compress the telescopic spring 7, storing elastic potential energy. After the horizontal insert 9 retracts into the storage seat 6, the operator inserts the embedded insert 2 on the surface of the tread plate body 1 into the interior of the mounting base 3. The embedded insert 2 enters the positioning cavity 5 of the limiting seat 4, and the installation is complete. Once in position, release the pull block 10, the telescopic spring 7 returns to its original position, and push the movable plate 8 and the horizontal insert 9 to extend. The horizontal insert 9 passes through the embedded insert 2 and fixes its position. At this time, release the vertical insert 11, which descends under the action of gravity and re-inserts into the horizontal insert 9 to lock the horizontal insert 9. When disassembling, the personnel pull the vertical insert 11 upward to unlock the horizontal insert 9, and then pull the pull block 10 to retract the horizontal insert 9 and disengage it from the embedded insert 2, so that the embedded insert 2 can be removed from the mounting base 3.

[0018] The embedded plug 2 is inserted into the inside of the positioning cavity 5, and the transverse plug 9 passes through the inside of the embedded plug 2. The embedded plug 2 can be accurately inserted into the inside of the positioning cavity 5, and the transverse plug 9 can pass through the inside of the embedded plug 2, so as to achieve a tight connection and fixation between the tread plate body 1 and the mounting base 3.

[0019] The vertical insertion rod 11 has a positioning hole 13 on its surface, and the vertical insertion rod 11 is inserted into the positioning hole 13.

[0020] The surface of the embedded plug 2 is provided with a limiting hole 14, which is adapted to the horizontal plug 9.

[0021] Both sides of the outer surface of the mounting base 3 are provided with opening slots 15. The opening slots 15 are adapted to the embedded plug 2. When the personnel insert the embedded plug 2 into the mounting base 3, the opening slots 15 can provide an accurate insertion channel for the embedded plug 2, guide the embedded plug 2 smoothly into the positioning cavity 5, and ensure that it can accurately cooperate with the positioning cavity 5 of the limiting seat 4, so as to realize the rapid assembly between the tread plate body 1 and the mounting base 3.

[0022] There are two embedded blocks 2, which are fixedly connected to both sides of the outer surface of the tread plate body 1.

[0023] The surface of the mounting base 3 is provided with a sliding hole that matches the vertical insertion rod 11, and the vertical insertion rod 11 is slidably connected to the surface of the mounting base 3.

[0024] The implementation principle of a high-speed train step plate in this application embodiment is as follows: First, the step plate body 1 is connected to the mounting base 3 through the embedded plug 2 fixed on its surface. In the initial state, the vertical plug 11 descends and inserts into the horizontal plug 9 under the action of gravity, locking the position of the horizontal plug 9. At this time, the telescopic spring 7 is not compressed, and the horizontal plug 9 is naturally inside the mounting base 3.

[0025] When installing the tread plate body 1 onto the mounting base 3, the operator first pulls the vertical insert rod 11 upwards to disengage it from the horizontal insert rod 9, unlocking the horizontal insert rod 9. When the limiting ring 12 contacts the inner top wall of the mounting base 3, the vertical insert rod 11 stops rising to prevent excessive upward movement and disengagement from the mounting base 3. Then, the operator pulls the pull block 10 to retract the movable plate 8, causing the horizontal insert rod 9 to retract and compress the telescopic spring 7, storing elastic potential energy. After the horizontal insert rod 9 retracts into the storage seat 6, the operator inserts the embedded insert 2 on the surface of the tread plate body 1 into the interior of the mounting base 3. The embedded insert 2 enters the positioning cavity 5 of the limiting seat 4. Finally, after installation, the operator releases the lever. Pull block 10, telescopic spring 7 resets, pushes movable plate 8 and horizontal insertion rod 9 to extend. When horizontal insertion rod 9 extends, it can be accurately inserted into the limiting hole 14, thereby fixing and limiting the position of embedded insertion block 2. At this time, release vertical insertion rod 11, which descends under the action of gravity and is inserted into horizontal insertion rod 9 again to lock horizontal insertion rod 9. The horizontal insertion rod 9 locks embedded insertion block 2, and the vertical insertion rod 11 locks horizontal insertion rod 9, achieving double locking. This ensures the stability of the tread plate body 1 after installation inside the mounting base 3, enabling it to work stably and facilitating personnel movement between the carriage and the platform.

[0026] When it is necessary to disassemble the tread plate body 1, the operator pulls the vertical insert 11 upward to unlock the horizontal insert 9. Then, the operator pulls the pull block 10 to retract the horizontal insert 9 and disengage it from the embedded insert 2, thereby unlocking the embedded insert 2. The operator can then remove the embedded insert 2 from the inside of the mounting base 3, completing the disassembly of the tread plate body 1. This design makes the disassembly process of the tread plate body 1 simple and quick, allowing the operator to disassemble the tread plate body 1 when it is not in use, and to quickly replace it when it is damaged, reducing maintenance time.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
