Description

The present invention relates to a centering device, and more specifically, the present invention relates to a centering device that not only can quickly return to its original position even when a coupler that connects front and rear vehicles rotates from side to side, but also can connect when an external force below a certain level is applied. The present invention relates to a centering device that can prevent a coupler from rotating and stably connect front and rear vehicles when connecting the front and rear vehicles by preventing the coupler from rotating.

Rail transport vehicles include couplers that connect adjacent vehicles to each other to form a train configuration, each coupler being coupled horizontally to facilitate coupling and movement of vehicles on curved tracks. It is formed so that it can be rotated within a predetermined angular range.
This means that when attempting to couple adjacent rail cars on a curved section of rail track, the couplers of adjacent cars must be aligned to be centered with the longitudinal axis of the rail car during the car bonding procedure. When this happens, there is a significant horizontal offset between the laterally adjacent couplers of the rail vehicle, which is formed to allow the couplers to rotate from side to side as described above.
However, the couplers are connected to each other by almost straight lines, and as mentioned above, the couplers are formed so that they can rotate left and right, so there is a problem that the couplers swing left and right during the process of connecting the vehicles, making it difficult to connect them stably. A point occurs.
Therefore, in order to solve this problem, a centering device is provided to prevent the coupler of a railway vehicle from rotating arbitrarily, but such a conventional centering device uses pneumatic or hydraulic pressure. Since centering is maintained, the structure is not only very complicated, but also occupies a large volume, resulting in considerable installation and maintenance costs.
Furthermore, even if a centering device is installed in the conventional coupler, it is difficult to connect the couplers because they can be easily rotated left and right due to external force.

The present invention was devised to solve such problems, and the purpose is to provide a side support member that supports both sides of a coupler provided in a railway vehicle, and a lower support member that supports the lower part of the coupler. When the coupler is rotated from side to side by an external force, the coupler is returned to its original position. When connecting railway vehicles, the administrator can separately set the position of the coupler. It is an object of the present invention to provide a centering device that can be easily connected without adjustment.

Another object of the present invention is that a return force unit is provided inside the centering member to provide an elastic force for returning the coupler to its original position when the coupler is rotated, and the return force unit includes a body made of a rubber material; a wing section provided on both sides of the body, and a pressure member that rotates in accordance with the rotation of the coupler is provided at the front part of the wing section, and the width of the pressure member is wider than the separation space of the wing section. By forming the blades to be large, the coupler can only rotate when the wings are pressurized on both sides and a force greater than the elastic force of the wings is applied, thereby preventing external forces from acting when the vehicle is coupled. It is an object of the present invention to provide a centering device that can stably maintain the center of a coupler even when the coupler is connected in a stable manner.

The present invention relates to a centering device 200 that is installed on a coupler for a railway vehicle and returns the coupler to its original position.As shown in FIGS. a pair of lateral support members 500 that support both sides of the lateral support member 500; a centering member 400 that rotates the lateral support members 500 to return the coupler 100 to its original position; and a centering member 400 that is installed at the bottom of the hinge portion 110 of the coupler 100. and an installation bracket 300 on which the centering member 400 is installed.
Therefore, when the coupler 100 installed on the railway vehicle rotates with reference to the hinge part 110 due to an external force acting on it, the centering device 200 of the present invention returns it to its original position. At the time of connection, the coupler 100 does not need to be controlled separately by the administrator to be in a fixed position, so that the coupler 100 can be stably coupled.

The centering member 400 includes a cover member 410 formed in a cylindrical shape with an open bottom, a return force unit 450 that is provided inside the cover member 410 and applies a return force to the cover member 410, and the cover. It includes a connecting member 430 that connects the member 410 and the side support member 500.
Here, a central protrusion 420 is formed at the center of the upper surface of the cover member 410 to protrude upward, and one end of the connecting member 430 is integrally connected to one side of the central protrusion 420. , the connecting member 430 is formed in a "V" shape, and the side supporting members 500 are connected to both sides of the other end, so that the cover member 410, the connecting member 430, and the side supporting members 500 rotate simultaneously. do.

Meanwhile, as described above, the cover member 410 is formed so that the lower part is open, and the lower part of the restoring force unit 450 installed inside is exposed to the outside. It is fixed to the end of the bracket 300.
Here, the restoring force unit 450 includes a central shaft 451 that is made of a hard material such as synthetic resin or metal and is provided at the center, and a body 452 that is made of rubber or synthetic rubber and is provided outside of the central shaft 451. The wing part 453 is formed of the same material as the body 452 on both sides of the body 452, and the reinforcing member 454 is provided on the side surface of the wing part 453 and made of synthetic resin or metal.
At this time, shaft holes (not shown) are formed at the edge of the center shaft 451 so as to pass vertically through them at regular intervals, and the end of the installation bracket 300 is formed to correspond to the shaft holes. A shaft hole (not shown) is formed in the center, into which the shaft 310 is inserted and fixed so that the central shaft 451 does not rotate.

A center hole (not shown) is formed in the center of the restoring force unit 450 and the center shaft 451 so as to pass through the center, and a rotation shaft 440 is provided therein. By being fixed to the center of the cover member 410, the cover member 410 is rotatably provided outside the return force unit 450.
Here, a first separating part 455 and a second separating part 456 are formed at the front and rear parts of the pair of wing parts 453 formed on both sides of the body 452, and the inner circumference of the cover member 410 A pressure member 412 is installed on one side of the surface, and the pressure member 412 is inserted into the first separation part 455 .
At this time, when the coupler 100 is rotated by an external force, the cover member 410 connected to the side support member 500 by the connecting member 430 rotates at the same angle and is installed on the inner peripheral surface of the cover member 410. The pressure member 412 also rotates and pressurizes one of the pair of wing sections 453, thereby causing a deformation that rotates backward with respect to the body 452.

Therefore, the shape of the restoring force unit 450 is deformed as shown in FIG. When the external force disappears, a restoring force acts on the pressure member 412 to return it to the original position, and the pressure member 412 returns to its original position.
Therefore, when the pressure member 412 installed on the inner circumferential surface of the cover member 410 returns, the cover member 410 and the side support member 500 return to their original positions, and the coupler 100 also moves to its original position due to the side support members 500. By returning to the normal position, the connector 100 stably returns to its normal position without the administrator having to directly control the direction of the coupler 100.

Meanwhile, the pressure member 412 is formed to correspond to the shape of the first separation part 455, and the pressure member 412 is formed to have a horizontal width larger than that of the first separation part 455. As a result, the pair of wing portions 453 are pressurized rearward.
That is, the return force unit 450 is formed as shown in FIG. 7 during initial manufacturing, but when the pressure member 412 is inserted into the first separation part 455, it is formed as shown in FIG. The wing portion 453 is deformed, and a restoring force is generated that tries to return to the original shape due to elastic force.

Therefore, by inserting the pressure member 412, an initial elastic force that did not exist originally acts, and if the external force acting on the coupler 100 is smaller than the initial elastic force, the coupler 100 If the coupler 100 does not rotate arbitrarily and it is necessary to rotate the coupler 100, the force applied to the coupler 100 is made larger than the initial elastic force and the coupler 100 is rotated.
Of course, the initial elastic force should be appropriately adjusted depending on the situation of the railway vehicle in which the coupler 100 is installed.

The reinforcing member 454 is made of a hard material such as synthetic resin or metal, and is formed into an arc shape corresponding to the outer surface of the wing portion 453 and is adhesively bonded to the outer surface of the wing portion 453. It is formed to be thicker than the upper and lower thicknesses, and is formed to protrude from the upper and lower parts of the wing section 453.
Here, the upper and lower parts of the restoring force unit 450 are respectively provided with disc-shaped guide plates 460, and the outer diameter of the guide plates 460 is the same as the inner diameter of the reinforcing member 454. , the guide plate 460 is positioned inside the reinforcing member 454 that protrudes up and down.
At this time, a rotation prevention protrusion 461 is further provided on one side of the guide plate 460 to be inserted into the first separation part 455, and the rotation prevention protrusion 461 has an arc shape and The length corresponds to the distance between the reinforcing members 454 located at the portions 455.

Here, a center hole (not shown) is formed in the center of the guide plate 460 so that the rotating shaft 440 passes through it vertically, and a shaft hole formed in the center shaft 451 is formed outside the center hole. Correspondingly, a shaft hole passing through the upper and lower sides is formed, and the guide plate 460 is also fixed so as not to rotate by the aforementioned shaft.
Therefore, the anti-rotation protrusion 461 of the guide plate 460 is provided so as to be in contact with the inner peripheral surface of the reinforcing member 454 installed on the outside of the wing section 453, so that the reinforcing member 454 is pushed backward by the pressure member 412. When the wing section 453 is deformed, the guide plate 460 prevents the wing section from contracting inwardly, and the wing section deforms in a direction that rotates backward along the outer peripheral surface of the guide plate 460. .

Further, the anti-rotation protrusion 461 formed on one side of the guide plate 460 provided at the upper and lower parts of the restoring force unit 450 is inserted into the upper and lower parts of the first separating part 455, respectively, and is inserted into the upper and lower parts of the first separating part 455, and 453 is pressurized and rotates backwards, when the other wing section 453 tries to rotate in the same direction, by preventing this, the elastic force caused by the deformation of the one wing section 453 is further increased. This will allow you to return to your original position more quickly.

Meanwhile, a housing part (not shown) into which the upper and lower ends of the central shaft 451 are inserted is formed in the center of the guide plate 460 so that the cover member 410 can be more easily assembled. The guide plate 460 can be easily assembled by forming an inner accommodating part (not shown) in the center of the inner lower surface of the guide plate 460 in which the accommodating part protruding upward from the guide plate 460 is accommodated.
At this time, a center hole (not shown) through which the upper end of the rotating shaft 440 passes vertically is formed in the center of the center protrusion 420 formed at the center of the upper surface of the cover member 410. The protrusion 420 is formed with a through hole that passes through the center protrusion 420 from side to side, so that the fixing pin 422 can be inserted into the inner side of the center protrusion 420 so as to pass through the rotating shaft 440 inside the center protrusion 420 from side to side. Fix it.

A lower support member 600 is further provided between the side support members 500, and the lower support member 600 includes a lower plate member 610 provided at the lower end of the side support member 500, and a lower plate member The connector 100 includes a buffer member 620 installed on the upper part of the connector 610 , and a lower support plate 630 installed on the upper part of the buffer member 620 to support the lower part of the coupler 100 .
Therefore, the buffer member 620 not only can stably support the load of the coupler 100, but also absorbs vertical vibrations that occur during driving, thereby improving riding comfort.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and the scope of the present invention extends to those that are substantially equivalent to the embodiments of the present invention. Various modifications can be made by those having ordinary knowledge in the technical field to which the invention pertains without departing from the spirit of the invention.
