Description

Technical Field

[0001] This utility model relates to the field of anti-climb device technology, specifically an anti-climb device for energy dissipation in train collisions. Background Technology

[0002] With the diversified development of train and railway technology, rail transit is showing more and more types. It is not uncommon for two cars to overlap in a rear-end collision. In order to ensure impact resistance, a series of energy-absorbing devices are set at the front of the car, which are composed of a coupler buffer device, an anti-climb device and a deformable structure of the car body, forming a three-level energy-absorbing protective barrier.

[0003] However, the existing anti-climb device uses a toothed structure that is prone to deformation during use, which makes the anti-climb device easily damaged, and then the two trains collide.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN221660733U discloses a collision energy dissipation anti-climb device for rail vehicles, comprising an energy-absorbing module and a buffer module. The energy-absorbing module includes a carriage, two front guard plates installed on the top and bottom of the carriage, an energy-dissipating insert plate slidably connected between the two front guard plates, and multiple reinforcing plates installed on the top and bottom of the carriage. The buffer module includes a base frame installed on one side of the carriage, multiple bushings connected to the base frame, a spring I embedded inside the bushing, and a plug shaft connected to the outer end of the spring I. When the energy-dissipating insert plate collides with an external train, the multiple springs I and multiple springs II buffer the impact force. Then, when the impact force is large, the energy-dissipating insert plate presses against the reinforcing plate, and the energy-dissipating insert plate transmits the impact force to the entire carriage, improving the collision resistance. Under this triple protection, the energy dissipation effect is improved, reducing the probability of two trains colliding.

[0005] The aforementioned device uses an energy-dissipating insert to press against a reinforcing plate during use, thereby transferring the collision force to the entire carriage. However, the device places excessively high demands on the compressive strength of the reinforcing plate. Due to the large kinetic energy generated by the train collision, the energy-dissipating insert damages the reinforcing plate, thus affecting the energy absorption effect and increasing costs. Utility Model Content

[0006] The purpose of this invention is to provide an anti-climbing device for energy dissipation in train collisions, in order to solve the problem mentioned in the background art that the large kinetic energy generated by the collision leads to easy damage to the reinforcing plate and affects the energy absorption effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-climbing device for train collision energy dissipation, comprising a toothed plate, a guide cylinder fixedly installed on the outer surface of the toothed plate, an energy dissipation box movably installed on the outer surface of the guide cylinder, an installation plate fixedly installed on the inner side of the energy dissipation box, and an energy dissipation coil fixedly installed on the inner side of the installation plate; the inner side of the energy dissipation box is provided with an energy absorption mechanism to prevent damage, the energy absorption mechanism including reinforcing plates fixedly installed on both sides of the installation plate.

[0008] Furthermore, a fixing plate is fixedly installed on the outer surface of the guide cylinder, and a buffer rod is fixedly installed on the side of the fixing plate away from the toothed plate.

[0009] Furthermore, the buffer rod is movably installed on the inner side of the reinforcing plate, and two sets of buffer rods are provided, with a spring wound around the outer surface of the two sets of buffer rods.

[0010] Furthermore, the spring is disposed between the fixed plate and the reinforcing plate, and a permanent magnet is fixedly installed on the outer surface of the reinforcing plate.

[0011] Furthermore, a connecting plate is fixedly installed on the side of the guide cylinder away from the toothed plate, and a permanent magnet is fixedly installed on the outer surface of the connecting plate.

[0012] Furthermore, a second spring is fixedly installed on the inner side of the energy dissipation box, and a buffer block is fixedly installed on the outer surface of the second spring.

[0013] Furthermore, a limiting rod is movably installed on the outer surface of the buffer block, and the limiting rod is fixedly installed on the inner side of the energy dissipation box.

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

[0015] (1) When a train collides, the toothed plate is used to connect with the car body of the colliding train to prevent the train from being subjected to a large impact force and derailing, thus protecting the safety of passengers. The guide tube and energy dissipation box are used to absorb the energy generated during the impact, thereby reducing the impact force, reducing the degree of damage to the train, improving the safety of the train, and reducing the maintenance cost.

[0016] (2) When the train is hit, the guide tube drives the fixed plate to move, and the fixed plate drives the buffer rod to move. The spring is used to relieve the impact force and absorb part of the kinetic energy.

[0017] (3) The buffer rod is guided by the baffle groove in the middle of the energy dissipation box. The buffer rod moves with the groove in the reinforcing plate. The baffle is strengthened by the reinforcing plate to avoid deformation caused by the impact force and extend the service life of the equipment.

[0018] (4) The guide cylinder drives the connecting plate to move, and the connecting plate drives the second permanent magnet to move. The second permanent magnet moves relative to the first permanent magnet. As the second permanent magnet moves, it cuts the magnetic field lines generated between the energy dissipation coils, thereby converting magnetic energy into electrical energy, causing the energy dissipation coil to generate current. The generated current is converted into heat energy through the installed energy dissipation resistor, reducing the generated kinetic energy. This is the second stage of energy absorption. Then the connecting plate reaches the position of the buffer block, using the second spring to relieve the generated impact force, and the buffer block is limited by the limit rod, thereby further reducing the generated impact force and reducing the risk of equipment damage.

[0026] 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.

[0027] Example 1: Please refer to Figures 1-5The present invention provides the following technical solution: an anti-climbing device for energy dissipation in train collisions, comprising a toothed plate 1, a guide cylinder 2 fixedly installed on the outer surface of the toothed plate 1, an energy dissipation box 3 movably installed on the outer surface of the guide cylinder 2, an installation plate 9 fixedly installed on the inner side of the energy dissipation box 3, and an energy dissipation coil 10 fixedly installed on the inner side of the installation plate 9; an energy absorption mechanism to prevent damage is provided on the inner side of the energy dissipation box 3, the energy absorption mechanism including reinforcing plates 7 fixedly installed on both sides of the installation plate 9.

[0028] When a train collision occurs, the toothed plate 1 connects with the car body of the colliding train to prevent the train from being derailed due to a large impact force, thus protecting the safety of passengers. Furthermore, the guide cylinder 2 and energy dissipation box 3 absorb the energy generated during the impact, thereby reducing the impact force, minimizing the damage to the train, improving the safety of the train, and reducing maintenance costs.

[0029] Example 2: Based on Example 1, please refer to... Figures 1-3 The buffer rod 5 was also disclosed, and its specific structure is as follows: a fixed plate 4 is fixedly installed on the outer surface of the guide cylinder 2, and a buffer rod 5 is fixedly installed on the side of the fixed plate 4 away from the toothed plate 1. The buffer rod 5 is movably installed on the inner side of the reinforcing plate 7. Two sets of buffer rods 5 are provided, and springs 6 are wound around the outer surface of the two sets of buffer rods 5. Springs 6 are located between the fixed plate 4 and the reinforcing plate 7. A permanent magnet 8 is fixedly installed on the outer surface of the reinforcing plate 7.

[0030] When the train is hit by a collision, the guide cylinder 2 drives the fixed plate 4 to move, and the fixed plate 4 drives the buffer rod 5 to move. The spring 6 is used to relieve the impact force and absorb part of the kinetic energy. This is the first stage of energy absorption. The baffle groove in the middle of the energy dissipation box 3 guides the buffer rod 5. The buffer rod 5 moves with the groove in the reinforcing plate 7. The reinforcing plate 7 increases the rigidity of the baffle and avoids deformation caused by the impact force, thus extending the service life of the equipment.

[0031] Example 3: Based on Example 1, please refer to... Figures 5-6 The buffer block 15 is also disclosed, and its specific structure is as follows: a connecting plate 11 is fixedly installed on the side of the guide cylinder 2 away from the toothed plate 1, a permanent magnet 12 is fixedly installed on the outer surface of the connecting plate 11, a spring 13 is fixedly installed on the inner side of the energy dissipation box 3, a buffer block 15 is fixedly installed on the outer surface of the spring 13, a limit rod 14 is movably installed on the outer surface of the buffer block 15, and the limit rod 14 is fixedly installed on the inner side of the energy dissipation box 3.

[0032] The guide cylinder 2 drives the connecting plate 11 to move, and the connecting plate 11 drives the permanent magnet 12 to move. The permanent magnet 12 moves relative to the permanent magnet 8. As the permanent magnet 12 moves, it cuts the magnetic field lines generated between the energy dissipation coils 10, thereby converting magnetic energy into electrical energy. This causes the energy dissipation coils 10 to generate current. The generated current is converted into heat energy through the installed energy dissipation resistor, reducing the generated kinetic energy. This is the second stage of energy absorption. Then, the connecting plate 11 reaches the position of the buffer block 15. The spring 13 is used to relieve the generated impact force, and the buffer block 15 is limited by the limit rod 14, thereby further reducing the generated impact force and reducing the risk of equipment damage.
