Description

Technical Field

[0001] This utility model relates to the technical field of safety devices for rail vehicles, specifically a multi-stage planing type anti-climb device for rail vehicles. Background Technology

[0002] In the field of modern rail transit, the operational safety of rail vehicles is of paramount importance. As a core component for ensuring vehicle collision safety, the performance of the anti-climb device directly affects the safety of passengers and the extent of vehicle damage in the event of an accident. The main function of the anti-climb device is to effectively absorb collision energy and prevent vehicles from climbing each other or overturning when vehicles collide or rear-end each other, thereby reducing the harm caused by the accident.

[0003] Existing anti-climb devices for rail vehicles can only provide single-stage buffering and energy absorption during use. When faced with high-intensity collisions, they cannot fully absorb the huge energy generated by the collision, resulting in the car still bearing a large impact force, which is difficult to meet the growing safety requirements. In addition, some anti-climb devices use a fixed buffer structure, which lacks adaptability to different working conditions and cannot flexibly adjust the energy absorption effect according to changes in collision intensity, reducing their versatility and practicality. Therefore, we have introduced a multi-stage planing type anti-climb device for rail vehicles. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This multi-stage planing-type anti-climb device for rail vehicles, through its anti-climb tooth assembly design, allows the anti-climb tooth body to absorb the impact energy upon a collision, transmitting it to the planing cylinder. This causes the piston plate to slide, and the first and second planing blades successively generate planing friction against the outer wall of the planing cylinder, dissipating the impact energy in stages. During the first stage of buffering, the first planing blade cooperates with the planing plate to initially buffer the impact force. Simultaneously, during the second stage of buffering, the second planing blade slides along the outer wall of the planing cylinder to the inner wall of the mounting groove, further absorbing energy and significantly reducing the impact force on the car body. Compared to traditional single-stage buffering anti-climb devices, this device can more effectively protect the safety of the vehicle and passengers.

[0015] 2. This multi-stage planing type anti-climb device for rail vehicles, through the setting of the recoil assembly, brings a unique energy conversion to the anti-climb device. During the buffer compression process between the second and first planing cylinders, the gas inside the second planing cylinder is compressed and transmitted through the energy transmission tube, pushing the push rod to drive the piston plate and flexible pad to move in the opposite direction of the collision, converting the collision energy into counter-propulsion energy, which then pushes back to buffer the colliding vehicle a second time, thereby further offsetting the collision force. At the same time, the compression and rebound of the springs two and three, the spring balls, and the reset of the flexible pad prepare for the next collision, effectively improving the adaptability of the anti-climb device to different collision conditions and enhancing its versatility and practicality.

[0016] 3. This multi-stage planing type anti-climb device for rail vehicles, through the setting of the connecting components, enables the sliding pin and rotating threaded rod to drive the arc-shaped sleeve and trapezoidal slider to cooperate and transmit power, so as to separate the car body plate from the second planing cylinder, thereby facilitating the inspection and replacement of the anti-climb tooth assembly, reducing maintenance time, lowering maintenance costs, and improving the applicability of the equipment.

[0027] 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.

[0028] Please see Figure 1 - Figure 6 A multi-stage planing type anti-climb device for rail vehicles includes a car body plate 1, a second planing cylinder 2 on the outer wall of the car body plate 1, an installation groove 3 on the inner wall of the second planing cylinder 2, a back-jet assembly 10 on the outer wall of the second planing cylinder 2, a first planing cylinder 4 fixedly mounted on the outer wall of the second planing cylinder 2, an installation groove 5 on the inner wall of the first planing cylinder 4, an anti-climb tooth assembly 6 on the inner wall of the second planing cylinder 2, slots 7 and 8 on the inner wall of the car body plate 1, and a connecting assembly 9 on the inner wall of the second planing cylinder 2.

[0029] The anti-climbing tooth assembly 6 includes a cutting cylinder 601, a piston plate 602 fixedly installed on the outer wall of the cutting cylinder 601, a connecting column 604 provided on the inner wall of the cutting cylinder 601, the piston plate 602 opened on the outer wall of the cutting cylinder 601, an anti-climbing tooth body 605 threadedly connected to the outer wall of the connecting column 604, a planing plate 606 threadedly connected to the outer wall of the cutting cylinder 601, a first cutting blade 607 movably connected to the inner wall of the second mounting groove 5, and a second cutting blade 608 movably connected to the inner wall of the first mounting groove 3.

[0030] The recoil assembly 10 includes an energy transmission tube 101, a push rod 102 is slidably connected to the inner wall of the energy transmission tube 101, a piston plate 103 and a flexible gasket 105 are fixedly mounted on the outer wall of the push rod 102, a spring 104 is provided on the outer wall of the push rod 102, an air pipe 106 is provided on the outer wall of the energy transmission tube 101, an air outlet 107 is fixedly mounted on the top of the air pipe 106, an air inlet 108 is fixedly mounted on the bottom of the air pipe 106, and an air inlet 108 and a ball 109 are provided in the inner cavity of the air pipe 106.

[0031] In the above structure, by setting the anti-climbing tooth assembly 6 and the recoil assembly 10, when a collision occurs with a vehicle, the anti-climbing tooth assembly 6 will perform a first stage of buffering through its first shearing cylinder 4. At the same time, after the first stage of buffering ends, the anti-climbing tooth assembly 6 will continue to extend through its second shearing cylinder 2 for a second stage of buffering. Meanwhile, the recoil assembly 10 will perform a second stage of buffering through the buffering compression between its second shearing cylinder 2 and the first shearing cylinder 4, thereby absorbing the collision energy and converting it into counter-propulsion energy to reduce the collision pressure on the vehicle body.

[0032] In a preferred embodiment: the connecting assembly 9 includes a connecting box 901, the inner wall of the connecting box 901 is provided with a sliding groove 902 and a guide groove 903 respectively, the inner wall of the slot 1 7 is slidably connected with a pin 904, the inner wall of the connecting box 901 is threadedly connected with a threaded rod 905, the outer wall of the threaded rod 905 is threadedly connected with an arc-shaped sleeve 906, the inner cavity of the connecting box 901 is provided with a trapezoidal slider 907, the outer wall of the trapezoidal slider 907 is fixedly installed with a pin 2 908, the outer wall of the pin 2 908 is provided with a spring 909, and the inner wall of the pin 2 908 is provided with a slot 3 910.

[0033] In a preferred embodiment: the outer wall of the arc sleeve 906 has the same shape as the inner wall of the guide groove 903, and the outer wall of the arc sleeve 906 is slidably fitted to the inner wall of the guide groove 903. The trapezoidal slider 907, pin 2 908, spring 1 909 and slot 3 910 are regarded as a movable component, and the movable component is respectively arranged opposite to each other with the threaded rod 905 as the center. The outer walls of the two trapezoidal sliders 907 are slidably fitted to the bottom of the arc sleeve 906. The outer walls of the two pins 2 908 are adapted to the inner wall of slot 2 8. The inner walls of the two slots 3 910 are adapted to the outer wall of pin 1 904.

[0034] In the above structure, by setting the arc-shaped sleeve 906, trapezoidal slider 907, pin 2 908, and pin 1 904, pin 1 904 slides along the inner wall of slot 1 7, causing pin 1 904 to disengage from the inner walls of the two slots 3 910. Then, by rotating its threaded rod 905 counterclockwise, the arc-shaped sleeve 906 slides along the inner wall of the guide groove 903 under the counterclockwise rotation of the threaded rod 905. The bottom of the sliding guide groove 903 disengages from the outer walls of the two opposing trapezoidal sliders 907. The two trapezoidal sliders 907 then slide along the inner wall of the slide groove 902 under the spring compression of spring 1 909. This causes pin 2 908 to disengage from the inner wall of its slot 2 8 under the drive of the trapezoidal slider 907, thereby achieving the disengagement between the body plate 1 and the second chipper 2, making the replacement of the anti-climbing tooth assembly 6 more convenient during maintenance.

[0035] In a preferred embodiment: the outer edges of the second cutting blade 608 and the first cutting blade 607 are the same shape as the outer walls of the cutting cylinder 601 and the planing plate 606, respectively, and the outer edges of the second cutting blade 608 and the first cutting blade 607 are slidably fitted to the outer walls of the cutting cylinder 601 and the planing plate 606. The outer edge of the second cutting blade 608 is adapted to the inner wall of the cutting groove 603, and the outer wall of the piston plate 1 602 is slidably fitted to the inner wall of the second cutting cylinder 2.

[0036] In the above structure, by setting the second cutter 608 and the first cutter 607, when the anti-climb tooth body 605 is involved in a vehicle collision, after absorbing the collision energy, it transmits it to the cutting cylinder 601. This causes the piston plate 602 to slide along the inner wall of the second cutting cylinder 2 under the push of the cutting cylinder 601. This causes the outer edges of the first cutter 607 and the second cutter 608 to generate planing friction with the outer wall of the cutting cylinder 601. At the same time, when the first cutter 607 contacts the outer wall of the planing plate 606, the friction generated provides the first stage of collision buffering for the anti-climb tooth body 605. During the first stage of buffering, the second cutter 608 slides along the outer wall of the cutting cylinder 601 into the inner wall of the cutter groove 603, thereby generating the second stage of buffering. This reduces the force on the anti-climb tooth body 605 and also reduces the pressure on the vehicle body.

[0037] In a preferred embodiment: the connecting component 9 is regarded as a set of movable components, and the movable components are respectively disposed on both sides of the outer wall of the second cutting cylinder 2. The outer walls of the two piston plates 103 are slidably disposed in contact with the inner wall of the energy transmission tube 101. The two spheres 109 are located at the bottom of the spring 110, and the diameter of the spheres 109 is larger than the opening diameter of the air inlet 108.

[0038] In the above structure, by setting the sphere 109 and the spring 110, the two piston plates 103 slide along the inner wall of the energy transmission tube 101 under the push of the gas. The two push rods 102 push the two flexible pads 105 to collide with the vehicle under the push of the piston plates 103. At the same time, the two push rods 102 also drive the two springs 104 to compress when sliding. When the two piston plates 103 slide to correspond to the air tube 106, the gas in the inner cavity of the energy transmission tube 101 pushes the sphere 109 through the piston plates 103. The sphere 109 drives the spring 110 to compress, so that the gas in the inner cavity of the air tube 106 is discharged through the push rods 102. Then, the compression and rebound of the springs 104 and 110 achieves the reset through the opposite operation.

[0039] In a preferred embodiment: one end of the two energy transfer tubes 101 is connected to the air outlet of the second cutting cylinder 2, and the other end is correspondingly disposed with respect to the outer wall of the second cutting cylinder 2;

[0040] In the above structure, the gas inside the second cutting cylinder 2 is discharged through the two energy transmission tubes 101 connected to its outlet under compression, thereby realizing the synchronous kinetic energy transmission of the two energy transmission tubes 101 for synchronous reverse thrust.

[0041] Working principle: When a rail vehicle collides with this device, the anti-climb tooth body 605 first absorbs the collision energy and transmits the energy to the cutting cylinder column 601. Under the action of energy, the cutting cylinder column 601 pushes the piston plate 602, causing the piston plate 602 to slide along the inner wall of the second cutting cylinder 2. At the same time, the outer edges of the first cutting blade 607 and the second cutting blade 608 generate planing friction with the outer wall of the cutting cylinder column 601, so that the first cutting blade 607 contacts the outer wall of the planing plate 606. Through friction, the anti-climb tooth body 605 is buffered in the first stage of collision.

[0042] Secondly, when transitioning from the first-stage buffer to the second-stage buffer, during the first-stage buffering process, the second cutter 608 slides along the outer wall of the cutter cylinder 601 to the inner wall of the cutter groove 603, starting the second-stage buffering. The interaction between the second cutter 608 and the inner wall of the cutter groove 603 further consumes the collision energy, reduces the impact force on the anti-climb tooth body 605, and thus reduces the collision pressure borne by the carriage.

[0043] Then, during the buffering and compression process between the second cutting cylinder 2 and the first cutting cylinder 4, the gas inside the second cutting cylinder 2 is compressed by the sliding of the piston plate 602. This causes the gas inside the second cutting cylinder 2 to be synchronously transmitted through the two energy transmission tubes 101 connected to the outlet end. The gas pushes the push rod 102 inside the energy transmission tube 101. The push rod 102 drives the piston plate 103 to slide along the inner wall of the energy transmission tube 101, while simultaneously pushing the flexible pad 105 to move in the opposite direction of the vehicle collision, performing a secondary buffering operation and converting the collision energy into reverse thrust energy. At the same time, the push rod 102... When sliding, the second spring 104 is compressed. When the second piston plate 103 slides to the position corresponding to the air pipe 106, the gas in the inner cavity of the energy transmission pipe 101 pushes the ball 109 through the second piston plate 103. The ball 109 drives the third spring 110 to compress. The gas is discharged in the inner cavity of the air pipe 106 through the push rod 102. After the collision ends, relying on the compression and rebound characteristics of the second spring 104 and the third spring 110, each component gradually resets through the operation opposite to the reverse push process, preparing for the next possible collision.

[0044] By using its anti-climbing tooth assembly 6, the first pin 904 is slid along the inner wall of the slot 7, disengaging it from the inner walls of the two slots 910. Then, the threaded rod 905 is rotated counterclockwise, causing the arc-shaped sleeve 906 to slide along the inner wall of the guide groove 903 under the action of the threaded rod 905. When the arc-shaped sleeve 906 slides to the bottom and disengages from the outer walls of the two opposing trapezoidal sliders 907, the two trapezoidal sliders 907 slide along the inner wall of the slide groove 902 under the spring compression action of the spring 909, thereby causing the two pins 908 to disengage from the inner walls of the slots 8, realizing the disengagement between the body plate 1 and the second shaving cylinder 2, which facilitates the maintenance or replacement of its anti-climbing tooth assembly 6.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
