Description
Technical Field
[0001] This application relates to the technical field of rail vehicles, and in particular to a tie rod device and anti-detachment method, and a folding windshield. Background Technology
[0002] In existing rail transit vehicles, a folding canopy windshield is installed between two cars to ensure their coupling. The folding canopy windshield acts as a bridge connecting two adjacent cars, facilitating passenger movement between them. The folding canopy windshield of a rail vehicle mainly consists of a folding canopy assembly, a tie rod assembly, a transition plate, and diagonal tie rods. The folding canopy assembly adopts a flexible structure design to connect adjacent cars. If the distance between the car ends is too large, the folding canopy assembly may sink or deflect excessively in all directions. Therefore, the tie rod assembly becomes a crucial component. The tie rod assembly connects the folding canopy to the car body or roof, bears the weight of the folding canopy, and is adjusted to ensure the folding canopy is in the correct position and angle.
[0003] Existing tie rod assemblies mainly include multiple components such as tension spring seats, tension springs, upper tie rods, connecting seats, and lower tie rods. As the structure connecting the canopy and the vehicle body, the tie rod assembly is easily affected by complex environments such as vibration, impact, and temperature changes during the operation of rail transit vehicles. Long-term working conditions may lead to fatigue and wear of the tie rod assembly components, which may result in component breakage. If the vehicle cannot be stopped and replaced in time, there is a high risk that the tie rod assembly components may fall off and be thrown out during the operation of the vehicle, thereby affecting the normal operation of the rail transit vehicle and even causing safety accidents. Summary of the Invention
[0004] To address the issue of components easily becoming damaged, detached, or thrown off in pull rod assemblies, this application provides a pull rod device and anti-detachment method, as well as a folding windshield.
[0005] The technical solutions provided in this application for a pull rod device and anti-detachment method, and a folding windshield, are as follows:
[0006] A pull rod device includes a pull rod, a tension spring seat, and a tension spring, wherein the tension spring is disposed between the pull rod and the tension spring seat; it also includes a rope, wherein the tension spring seat, the tension spring, and the pull rod are connected in a closed loop by the rope, and the rope is used to prevent the pull rod, the tension spring seat, and the tension spring from falling off and being thrown out.
[0007] By adopting the above technical solution, this application utilizes ropes to connect the tie rod, tension spring seat, and tension spring to achieve a closed-loop connection of the tie rod device. In the event of a breakage of the tie rod device during the operation of rail transit vehicles, the closed-loop connection of the ropes can firmly connect the tension spring seat, tension spring, and tie rod together, effectively preventing the tie rod, tension spring seat, and tension spring from falling off due to breakage, thereby improving the safety and reliability of the entire tie rod device. Furthermore, the closed-loop connection method of the ropes is simple and convenient, which can simplify the structure of the entire tie rod device, reduce the number of parts, reduce manufacturing costs, and improve assembly efficiency.

The rope and the pull ring are connected by cross loops, which are arc-shaped loops formed by the rope crossing through the pull ring. Both the rope loops and the cross loops are fixed to the main body of the rope by pressure sleeves.

[0012] In one specific implementation, the pull rod includes a pull rod and a pull rod adjustment seat. The pull rod is disposed between the pull ring and the pull rod adjustment seat, and the rope extends out of the pull ring and is connected to the pull rod adjustment seat through the rope loop.
[0013] By adopting the above technical solution, a rope is passed through one side of the pull ring and connected to the pull rod adjustment seat through the rope loop, ensuring a firm connection between the pull rod adjustment seat and the rope; this connection method not only withstands a certain tension, but also maintains the stability of the connection, avoiding the problem of loosening or falling off.
[0014] In one specific implementation, the pull rod is threadedly connected to the pull rod adjusting seat for adjusting the length of the pull rod device.
[0015] By adopting the above technical solution, on the one hand, the threaded connection provides a stable connection method, ensuring that the connection between the pull rod and the pull rod adjustment seat is firm and not easy to loosen or fall off; on the other hand, the threaded connection method is simple to operate, and the length can be adjusted by simply rotating the thread, which makes it easy for users to quickly adjust the length of the pull rod device and simplify the adjustment process.
[0016] In one specific implementation, wear-resistant sleeves are fitted onto the rope loop and the cross loop.
[0017] By adopting the above technical solution, the wear-resistant sleeve can reduce the friction between the rope loop and the components of the cross loop and the tie rod device, reduce the degree of wear, improve its durability and stability, and extend the service life of the rope and related components.
[0018] In one specific implementation, the ends of the rope are connected by a connecting sleeve to form a closed loop connection.
[0019] By adopting the above technical solution, the ends of the rope are connected by a connecting sleeve, thereby achieving the purpose of forming a closed loop connection between the tension spring seat, tension spring, and tension rod through the rope; and the connecting sleeve can ensure a firm rope connection, which is beneficial to improving the reliability and safety of the entire tension rod device.

This design improves the reliability and safety of the tie rod device and is an effective method to prevent slippage.
[0023] In one specific implementation scheme, the method specifically includes: S1, wrapping the rope around the mounting ring of the tension spring seat, forming a rope loop on the mounting ring by folding back, and using a pressure sleeve to connect the rope loop to the rope body, thereby completing the connection between the rope and the tension spring seat;

[0034] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0035] Example 1
[0036] Reference Figure 1 and 2 This application discloses a pull rod device. In this embodiment, the pull rod device is applied to a rail transit vehicle. The pull rod device includes a pull rod 3, a tension spring seat 1, and a tension spring 2. The tension spring 2 is disposed between the pull rod 3 and the tension spring seat 1 and is connected to the pull rod 3 and the tension spring seat 1. The tension spring seat 1 is provided with a mounting ring 11. In this embodiment, the mounting ring 11 can be, but is not limited to, a horseshoe ring. The mounting ring 11 is hinged and rotatably disposed on the tension spring seat 1. The tension spring seat 1 is also provided with a mounting hole for mounting the tension spring seat 1 onto the vehicle body. Both ends of the tension spring 2 are provided with rings 21. In this embodiment, the tension spring 2 and the two rings 21 are integrally formed from spring steel wire with a diameter of 8mm. The pull rod 3 is provided with a pull ring 31. In this embodiment, the pull ring 31 and the pull rod 3 are integrally formed. The rings 21 of the tension spring 2 are respectively connected to the mounting ring 11 of the tension spring seat 1 and the pull ring 31 of the pull rod 3 to realize the installation of the pull rod device.
[0037] It also includes a rope 4. In this embodiment, the rope 4 includes, but is not limited to, a rope 4 with a diameter of 3mm and a length of 2m made of multiple 304 stainless steel wire ropes. The 304 stainless steel wire rope has high strength and wear resistance and can withstand large tension and weight loads. The tension spring seat 1, tension spring 2, and tension rod 3 are connected in a closed loop by the rope 4. The rope 4 is connected to the mounting ring 11 of the tension spring seat 1, then passes through the tension spring 2 to connect to the pull ring 31 and connects to the tension rod 3. The rope 4 is used to prevent the tension rod 3, tension spring seat 1, and tension spring 2 from falling off and being thrown out.
[0038] During installation, two rings 21 are connected to the mounting ring 11 and the pull ring 31 respectively, realizing the connection between the tie rod 3, the tension spring seat 1 and the tension spring 2. Then, the rope 4 is first connected to the mounting ring 11, then passes through the ring 21 of the tension spring 2 and is connected to the pull ring 31, thus forming a closed-loop connection between the tie rod 3, the tension spring seat 1 and the tension spring 2. This application uses the rope 4 to connect the tie rod 3, the tension spring seat 1 and the tension spring 2 to realize the closed-loop connection of the tie rod device. In the event of a breakage of the tie rod device during the operation of the rail transit vehicle, the closed-loop connection of the rope 4 can firmly connect the tension spring seat 1, the tension spring 2 and the tie rod 3 together, effectively preventing the tie rod 3, the tension spring seat 1 and the tension spring 2 from falling off due to breakage, thereby improving the safety and reliability of the entire tie rod device. Moreover, the closed-loop connection method of the rope 4 is simple and convenient, which can simplify the structure of the entire tie rod device, reduce the number of parts, reduce manufacturing costs and improve assembly efficiency.
[0039] The pull rod 3 includes a pull rod 32 and a pull rod adjusting seat 33. The pull rod 32 is located between the pull ring 31 and the pull rod adjusting seat 33. In this embodiment, the pull rod 32 is made of stainless steel rod with a diameter of 10 mm, but is not limited to it. The rope 4, the mounting ring 11 of the tension spring seat 1, and the pull rod adjusting seat 33 of the pull rod 3 are all connected by a rope ring 41. The rope ring 41 is an arc-shaped loop formed by folding the rope 4.
[0040] The rope 4 is connected to the pull ring 31 of the pull rod 3 through the cross ring 42. The cross ring 42 is an arc-shaped loop formed by the rope 4 passing through the pull ring 31. Both the rope ring 41 and the cross ring 42 are fixed to the main body of the rope 4 through the pressure sleeve 5, which increases the firmness and stability of the connection. The ends of the rope 4 are connected through the connecting sleeve 6 to form a closed loop connection, ensuring the safety and stability of the overall connection.
[0041] In this embodiment, the pressure sleeve 5 and the connecting sleeve 6 include, but are not limited to, a "figure-eight" aluminum pressure sleeve 5. On the one hand, the shape design of the "figure-eight" aluminum pressure sleeve 5 is easy to operate, as it has two openings. Users only need to insert the rope 4 into the openings and then use appropriate tools to tighten the pressure sleeve 5 to complete the connection. On the other hand, the "figure-eight" aluminum pressure sleeve 5 has excellent strength and durability. It can withstand large tensile and compressive forces, maintain the stability and safety of the connection, and also has good corrosion resistance, which can maintain the stability of the connection in humid environments or when exposed to the outdoors, thus meeting the needs of applications that require long-term use or exposure to harsh conditions.
[0042] During installation, the design of rope loop 41 and cross loop 42, along with the design of pressure sleeve 5 to fix rope loop 41 and cross loop 42, makes the connection between rope 4 and mounting ring 11, tie rod 3 and pull ring 31 more secure and reliable. This connection method can not only withstand a certain tension, but also maintain the stability of the connection and avoid loosening or falling off. Then, the connecting sleeve 6 is used to connect the ends of rope 4 to form a closed loop connection, thereby achieving the purpose of rope 4 forming a closed loop connection between tension spring seat 1, tension spring 2 and tie rod 3. This can prevent the tie rod device components from breaking and falling off, thereby improving the reliability and safety of the entire tie rod device.
[0043] The pull rod 32 is threadedly connected to the pull rod adjusting seat 33 for adjusting the length of the pull rod device. In this embodiment, the pull rod 32 is provided with a threaded part 321, and the pull rod adjusting seat 33 is provided with a threaded groove. The threaded connection is achieved through the threaded part 321 and the threaded groove. On the one hand, the threaded connection provides a stable connection method, ensuring that the connection between the pull rod 32 and the pull rod adjusting seat 33 is firm and not easy to loosen or fall off. On the other hand, the threaded connection method is simple to operate. The length adjustment can be completed by simply rotating the thread, which makes it convenient for users to quickly adjust the length of the pull rod device. When it is necessary to adjust the length of the pull rod 32, the extension and retraction adjustment between the pull rod 32 and the pull rod adjusting seat 33 can be achieved by rotating the threaded part 321 of the pull rod 32. Users can easily adjust the length of the pull rod 32 according to actual needs to adapt to different working environments or requirements, which has high flexibility and adjustability.
[0044] This application also provides a folding windshield, which includes the tie rod device as described above. In this embodiment, the folding windshield is installed between two cars of a rail transit vehicle to ensure the connection between the two cars. The folding windshield serves as a bridge connecting two adjacent cars, facilitating passengers to move back and forth between the cars. In this embodiment, the tie rod device is used to connect the folding windshield to the car body or roof, bears the weight of the folding windshield, and adjusts the length of the tie rod device by adjusting the length of the tie rod 3 to ensure that the folding windshield is in the correct position and angle, thereby enabling the folding windshield to be accurately positioned and stably connected to two adjacent cars.
[0045] The implementation principle of Embodiment 1 is as follows: This application mainly uses rope 4 to connect the pull rod 3, the tension spring seat 1 and the tension spring 2 to achieve a closed-loop connection of the pull rod device. This can prevent the pull rod 3, the tension spring seat 1 and the tension spring 2 from falling off and being thrown out due to breakage, thereby improving the safety and reliability of the entire pull rod device. Furthermore, the closed-loop connection method of rope 4 is simple and convenient, which can simplify the structure of the entire pull rod device, reduce the number of parts, reduce manufacturing costs and improve assembly efficiency.
[0046] During installation, the two rings 21 are connected to the mounting ring 11 and the pull ring 31 respectively to achieve the connection between the pull rod 3, the spring seat 1 and the spring 2. Then, the rope 4 is first connected to the mounting ring 11 through the rope ring 41 and fixed with the pressure sleeve 5. Then, the rope 4 is passed through the ring 21 of the spring 2. Then, the rope 4 is crossed and passed through the pull ring 31, connected to the pull ring 31 through the cross ring 42 and fixed with the pressure sleeve 5. Then, the rope 4 is connected to the pull rod adjusting seat 33 through the rope ring 41 and fixed with the pressure sleeve 5. Finally, the end of the rope 4 is connected through the connecting sleeve 6 to form a closed loop connection, thereby forming a closed loop connection between the pull rod 3, the spring seat 1 and the spring 2.
[0047] In the event of breakage of the tension spring seat 1, tension spring 2, and tension rod 3 in the tie rod device, the rope 4 connects the tension spring seat 1, tension spring 2, and tension rod 3 in a closed loop. Even if breakage occurs, the components will not fall off or be thrown out, thereby avoiding potential safety hazards and improving the safety and reliability of the entire tie rod device.
[0048] Example 2
[0049] This embodiment provides a method for preventing the pull rod device described in Embodiment 1 from detaching. Please refer to the structural diagram of the pull rod device. Figure 1 and Figure 2 As shown, the method includes:
[0050] S1. Connect the rope 4 to the tension spring seat 1. Specifically, wrap the rope 4 around the mounting ring 11 of the tension spring seat 1, and form a rope loop 41 by folding back on the mounting ring 11. Use the pressure sleeve 5 to connect the rope loop 41 to the main body of the rope 4 to complete the connection between the rope 4 and the tension spring seat 1.
[0051] S2. Then pass both ends of the rope 4 through the tension spring 2;
[0052] S3. Connect the rope 4 that passes through the tension spring 2 to the pull rod 3. Specifically, cross the two ends of the rope 4 that passes through the tension spring 2 through the pull ring 31 to form a cross loop 42 at the pull ring 31. Use the pressure sleeve 5 to connect the cross loop 42 to the main body of the rope 4 to complete the connection between the rope 4 and the pull ring 31. Then, wrap one end of the rope 4 around the pull rod adjusting seat 33 and fold it back to form a rope loop 41. Use the pressure sleeve 5 to connect the rope loop 41 to the main body of the rope 4 to complete the connection between the rope 4 and the pull rod adjusting seat 33, thereby completing the connection between the rope 4 and the pull rod 3.
[0053] S4. Form a closed loop connection at the end of the rope 4; specifically, connect the end of the rope 4 with the connecting sleeve 6 so that the rope 4 connects the tension spring seat 1, the tension spring 2 and the tension rod 3 in a closed loop.
[0054] During the operation of rail transit vehicles, the tie rod device is affected by complex environments such as vibration, impact, and temperature changes. There may be cases where the tension spring seat 1 and / or tension spring 2 and / or tie rod 3 in the tie rod device break. At this time, since the rope 4 connects the tension spring seat 1, tension spring 2 and tie rod 3 in a closed loop, even if a break occurs, the components will not fall off and be thrown out, thereby avoiding potential safety hazards. This design improves the reliability and safety of the tie rod device and is an effective anti-detachment method.
[0055] Example 3
[0056] The overall structure of this embodiment is the same as that of the pull rod device in Embodiment 1. Please refer to [link / reference]. Figure 1 and Figure 2 As shown; the difference between this embodiment and embodiment one is that wear-resistant sleeves are fitted on the rope loop 41 and cross loop 42 of the rope 4. In this embodiment, the wear-resistant sleeves include, but are not limited to, nylon sleeves and rubber sleeves. When the rope loop 41 or cross loop 42 comes into contact with other objects, friction will cause wear on the surface of the rope 4, reducing its service life and increasing safety risks. At this time, the added wear-resistant sleeves can reduce friction, protect the surface of the rope 4, reduce the degree of wear, and thus extend the service life of the rope 4 and the connecting parts. The wear-resistant sleeves can effectively protect the rope 4 and the connecting parts from wear and damage by external factors, thereby improving the service life of the entire pull rod device.
[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
