Description

Technical Field

[0001] This invention relates to the field of railway transportation technology, specifically to a chain jamming and anti-derailment mechanism for rail vehicles. Background Technology

[0002] Railway transportation tasks include two main categories: transporting passengers and transporting goods. Passenger trains, depending on their purpose, are mainly composed of cars such as hard-seat cars, hard-sleeper cars, soft-seat cars, soft-sleeper cars, dining cars, and baggage cars coupled together. Since railway cars are assembled and run in formation, there are couplers between the cars to facilitate train assembly, disassembly, and shunting operations. In addition, each car has its own braking and stopping device, and the braking and releasing operations are carried out on the locomotive at the end of the train.

[0003] To ensure that the vehicle braking devices can coordinate and operate in unison throughout the train, the air braking system is connected by hoses after adjacent cars are coupled. The hose coupling mainly consists of dust plugs, chains, and hose assemblies. After the hose connector of the tail car is coupled with the dust plug, the main air hose connector and dust plug of the passenger car are relatively low to the rail surface. They are hooked to the coupling seat by chain buckles. The distance between the hose and the rail surface is adjusted by adjusting the effective length of the chain buckles. After the hoses of the intermediate cars are coupled, the dust plug chains are hooked to the coupling seat for later use.

[0004] However, since the dustproof chain plug is prone to detaching from the bracket during the operation of vehicles with traditional brackets, it poses a safety hazard by causing the main air hose connector or chain plug to hit or even fall off the ground device. To address this issue, we propose a chain plug anti-detachment mechanism for rail vehicles. Summary of the Invention

[0005] This invention provides a chain blockage prevention mechanism for rail vehicles, which solves the safety hazard of dust blockage chains easily detaching from the mounting brackets during vehicle operation when traditional mounting brackets are installed, causing the main air hose connector or chain blockage to strike or even fall off the ground device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chain jamming prevention mechanism for rail vehicles, comprising:

[0007] Connector;

[0008] Mounting base, the front surface of the connector is provided with a mounting base, and the surface of the mounting base is movably fitted with an anti-disengagement retaining ring;

[0009] The connector has a chain plug, a bearing assembly fixedly connected to its bottom, a bearing housing movably connected to the inner cavity of the bearing assembly, and a chain plug fixedly connected to the bottom of the bearing housing.

[0010] The first spiral anti-detachment bracket is movably provided in the inner cavity of the chain plug, and the top of the first spiral anti-detachment bracket is fixedly connected to the second spiral anti-detachment bracket.

[0011] The second spiral anti-detachment hanger has a fixing mechanism that is movably provided in the inner cavity of the second spiral anti-detachment hanger. The fixing mechanism is used to fix the second spiral anti-detachment hanger.

[0012] Preferably, the bottom of the chain plug is provided with a first locking block, the inner cavity of the connector is fixedly connected with a second locking block, the bottom of the connector is fixedly connected with a third locking block, and the surface of the third locking block is slidably connected to the top of the chain plug.

[0013] Preferably, the inner cavity of the anti-detachment retaining ring is provided with mounting bolts, the inner cavity of the anti-detachment retaining ring is provided with a limiting rope, and a fixing ring is fixedly connected to the side of the limiting rope away from the anti-detachment retaining ring.

[0014] Preferably, the fixing mechanism includes a connecting block, the back surface of the connecting block is provided with an external carriage, the front surface of the connecting block is fixedly connected with a support frame, the front surface of the connecting block is fixedly connected with a connecting frame, the inner cavity of the connecting frame is fixedly connected with a support rod, the surface of the support rod is movably sleeved with a first spring, the bottom of the first spring is fixedly connected to the inner cavity of the connecting frame, and the surface of the support rod is movably sleeved with a fixing plate.

[0015] Preferably, a square root-shaped limiting plate is movably connected to the top of the support frame via a bearing, a limiting rod is fixedly provided on the top of the square root-shaped limiting plate, and support blocks are fixedly connected to both the left and right sides of the top of the support frame.

[0016] Preferably, a limiting frame is fixedly connected to the top of the support block, and the inner cavity of the limiting frame is slidably connected to the surface of the limiting rod.

[0017] Preferably, a second spring is fixedly provided on the inner side of the support block, and the front side of the second spring is fixedly connected to the rear side of the square root-shaped limiting plate.

[0021] This invention provides a chain jamming prevention mechanism for rail vehicles. Compared with the prior art, it has the following advantages:

[0022] The anti-detachment chain plug mechanism for this rail vehicle uses a mounting base to fix the connector to one side of the second car. Since the connecting block is fixed to one side of the first car, the buckle can be fitted onto the fixing plate. Pushing the fixing plate downward causes it to move the buckle downward, causing the square root-shaped limiting plate to rotate to both sides, positioning the fixing plate at the bottom of the square root-shaped limiting plate. At this point, a second spring pushes the square root-shaped limiting plate upward, and the limiting rod and limiting frame allow the square root-shaped limiting plate to engage with the fixing plate. Then, a first spring causes the fixing plate to move upward, limiting the buckle with the square root-shaped limiting plate, thus quickly fixing the buckle. After the buckle is fixed, the hole on the chain plug slides down along the spiral line on the first spiral anti-detachment bracket, completing the chain plug fixation. Then, a fixing ring is fixed to the inner cavity of the first spiral anti-detachment bracket, limiting the chain plug and preventing it from falling off. This completes the fixation between the first spiral anti-detachment bracket, the fixing mechanism, and the connector. Attached Figure Description

[0030] like Figures 1-6 The present invention provides two technical solutions, specifically including the following embodiments: Example

[0031] A chain jamming and anti-derailment mechanism for rail vehicles includes:

[0032] Connector 1; Connector 1 is used to secure chain plug 11 and mounting base 2.

[0033] Mounting seat 2, the front surface of connector 1 is provided with mounting seat 2, and the surface of mounting seat 2 is movably fitted with anti-detachment retaining ring 3; mounting seat 2 is used to fix the mounting position of the second carriage, thereby connecting the two carriages.

[0034] The bottom of the chain plug 11 and the connector 1 is fixedly connected to a bearing 8. The inner cavity of the bearing 8 is movably connected to a bearing seat 12. The bottom of the bearing seat 12 is fixedly connected to the chain plug 11. The bearing 8 allows the chain plug 11 to rotate, making it easy to adjust the position of the chain plug 11.

[0035] The first spiral anti-detachment bracket 15 is movably provided in the inner cavity of the chain plug 11, and the top of the first spiral anti-detachment bracket 15 is fixedly connected to the second spiral anti-detachment bracket 14; the spiral structure on the first spiral anti-detachment bracket 15 makes it difficult for the chain plug 11 to fall off the first spiral anti-detachment bracket 15.

[0036] The fixing mechanism 7 is movably provided in the inner cavity of the second spiral anti-detachment bracket 14. The fixing mechanism 7 is used to fix the second spiral anti-detachment bracket 14. More specifically, the connector 1 is fixed to one side of the second car body through the mounting base 2. Since the connecting block 701 is fixed to one side of the first car body, the buckle 703 can be sleeved on the fixing plate 711. At this time, the fixing plate 711 is pushed down, so that the fixing plate 711 drives the buckle 703 to move downward, so that the square root limiting plate 710 rotates to both sides, so that the fixing plate 711 is located at the bottom of the square root limiting plate 710. At this time, the second spring 708 pushes the square root limiting plate 710 to move upward, through the set limiting rod 712 and limiting frame 7. The limit of 09 causes the square root-shaped limit plate 710 to engage with the fixing plate 711. At this time, the first spring 706 causes the fixing plate 711 to move upward. The square root-shaped limit plate 710 limits the buckle 703, completing the quick fixing of the buckle 703. After the buckle 703 is fixed, the hole on the chain plug 11 slides down along the spiral line on the first spiral anti-detachment bracket 15, completing the fixing of the chain plug 11. At this time, the fixing ring 6 is fixed on the inner cavity of the first spiral anti-detachment bracket 15. The fixing ring 6 limits the chain plug 11 to prevent the chain plug 11 from falling off, completing the fixing between the first spiral anti-detachment bracket 15, the fixing mechanism 7, and the connector 1.

[0037] The bottom of the chain plug 11 is provided with a first locking block 13, the inner cavity of the connector 1 is fixedly connected with a second locking block 9, the bottom of the connector 1 is fixedly connected with a third locking block 10, and the surface of the third locking block 10 is slidably connected to the top of the chain plug 11; more specifically, by setting the third locking block 10, the second locking block 9 and the first locking block 13, the connection between the connector 1 and the chain plug 11 is stable, which facilitates the use of the device.

[0038] The inner cavity of the anti-detachment retaining ring 3 is provided with mounting bolts 4 and limiting ropes 5. A fixing ring 6 is fixedly connected to the side of the limiting rope 5 away from the anti-detachment retaining ring 3. More specifically, the limiting rope 5 and the fixing ring 6 limit the chain plug 11 to prevent it from falling off, thus completing the fixation between the first spiral anti-detachment bracket 15, the fixing mechanism 7 and the connector 1, facilitating the use of the device and preventing the hose from falling off.

[0039] The fixing mechanism 7 includes a connecting block 701. The back surface of the connecting block 701 is provided with an external carriage. The front surface of the connecting block 701 is fixedly connected to a support frame 702. The front surface of the connecting block 701 is fixedly connected to a connecting frame 704. The inner cavity of the connecting frame 704 is fixedly connected to a support rod 705. A first spring 706 is movably sleeved on the surface of the support rod 705. The bottom of the first spring 706 is fixedly connected to the inner cavity of the connecting frame 704. A fixing plate 711 is movably sleeved on the surface of the support rod 705. More specifically, the fixing plate 711 drives the buckle 703 to move downward, causing the square root-shaped limiting plate 710 to rotate to both sides, so that the fixing plate 711 is located at the bottom of the square root-shaped limiting plate 710. At this time, the second spring 708 pushes the square root-shaped limiting plate 710 to move upward, which facilitates the limiting of the buckle 703, thereby limiting the second spiral anti-detachment hanger 14.

[0040] The top of the support frame 702 is movably connected to a square root-shaped limiting plate 710 via a bearing. A limiting rod 712 is fixedly installed on the top of the square root-shaped limiting plate 710. Support blocks 707 are fixedly connected to both the left and right sides of the top of the support frame 702. More specifically, the square root-shaped limiting plate 710 is pushed upward by a second spring 708. The limiting rod 712 and the limiting frame 709 limit the square root-shaped limiting plate 710 to engage with the fixing plate 711. At this time, the fixing plate 711 is moved upward by a first spring 706. The square root-shaped limiting plate 710 limits the buckle 703, allowing the buckle 703 to be quickly disassembled and assembled, facilitating the use of the chain stopper 11.

[0041] The top of the support block 707 is fixedly connected to a limiting frame 709, and the inner cavity of the limiting frame 709 is slidably connected to the surface of the limiting rod 712; more specifically, the limiting frame 709 and the limiting rod 712 are used to limit the square root-shaped limiting plate 710, which facilitates the fixing of the fixing plate 711.

[0042] A second spring 708 is fixedly provided on the inner side of the support block 707. The front side of the second spring 708 is fixedly connected to the rear side of the square root-shaped limiting plate 710. More specifically, the second spring 708 enables the square root-shaped limiting plate 710 to be reset, so that the square root-shaped limiting plate 710 can limit the fixed plate 711.

[0043] The surface of the fixing plate 711 is movably connected with a buckle 703, and the inner cavity of the buckle 703 is movably connected with the inner cavity of the second spiral anti-detachment bracket 14; more specifically, the buckle 703 enables the second spiral anti-detachment bracket 14 to be fixed to the carriage, thereby completing the installation between the connector 1 and the chain plug 11.

[0044] The surface of the fixing plate 711 is slidably connected to the inner cavity of the connecting frame 704, and the bottom of the fixing plate 711 is fixedly connected to the top of the first spring 706; more specifically, the fixing plate 711 can be reset by the first spring 706, so that the fixing plate 711 can limit the buckle 703.

[0045] The surface of the second card block 9 is slidably connected to the surface of the chain block 11.

[0046] In this design, the first spiral anti-detachment mount 15 and the second spiral anti-detachment mount 14 are integrated for ease of manufacturing. They are formed by bending steel bars and are connected by a connecting rod 16. Furthermore, to improve reliability and prevent the retaining ring 6 from detaching from the first spiral anti-detachment mount 15 due to vibrations during vehicle operation, the first spiral anti-detachment mount 15 includes a hook 151 and a spiral anti-detachment component 152. The hook 151 is connected to the lower end of the connecting rod 16 and hooks the retaining ring 6, while the spiral anti-detachment component 152 is spirally wound around the connecting rod 16, forming a gap between them. In use, the retaining ring 6 is fitted onto the spiral anti-detachment component 152 and rotates around the connecting rod along the spiral trajectory of the component, eventually being held in place by the hook 151 at the bottom. During vehicle operation, the retaining ring 6 will be unable to detach from the spiral anti-detachment component 152 at the top due to the restriction, thereby ensuring that the retaining ring 6 is reliably suspended and fixed.

[0047] Working principle: Connector 1 is fixed to one side of the second carriage via mounting base 2. Since connecting block 701 is fixed to one side of the first carriage, buckle 703 can be sleeved on fixing plate 711. Pushing fixing plate 711 downwards causes buckle 703 to move downwards, causing square root-shaped limiting plate 710 to rotate to both sides, positioning fixing plate 711 at the bottom of square root-shaped limiting plate 710. At this point, second spring 708 pushes square root-shaped limiting plate 710 upwards. Through the limiting rod 712 and limiting frame 709, square root-shaped limiting plate 710 moves against fixing plate 711. When the chain is engaged, the first spring 706 causes the fixing plate 711 to move upward, and the square root-shaped limiting plate 710 limits the buckle 703, thus quickly fixing the buckle 703. After the buckle 703 is fixed, the hole on the chain plug 11 slides down along the spiral line on the first spiral anti-detachment bracket 15, thus fixing the chain plug 11. At this time, the fixing ring 6 is fixed on the inner cavity of the first spiral anti-detachment bracket 15, and the fixing ring 6 limits the chain plug 11 to prevent it from falling off, thus completing the fixing between the first spiral anti-detachment bracket 15, the fixing mechanism 7, and the connector 1.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
