Description

Technical Field

[0001] The utility model relates to the technical field of railway stopping, in particular to a buffer device. Background Art

[0002] In metallurgical, mining and other enterprises that require railway transportation, there is a part of the railway end line, which is generally used to undertake the task of loading and unloading goods, and is often used as a place for temporary parking of vehicles. When entering and exiting the railway end line, loading and unloading goods or temporarily parking, in order to prevent vehicles from slipping out of the railway and causing accidents, it is necessary to install a car stop at the end of the railway. It is an important protective device for railway transportation safety. It can not only effectively prevent vehicles from slipping out of the end line, but also protect the safety of the railway, car stops and the vehicle itself.

[0003] In the prior art, there is a buffer-type wheel stopper for railways with patent announcement number: CN219821430U, which includes: a buffer assembly, which is detachably mounted on the upper surface of the rail; wherein the buffer assembly includes a crescent plate and a buffer mounted on one end of the crescent plate. The device is provided in the utility model. When a vehicle collides with the crescent plate, the crescent plate moves backward with the wheel, driving the damping plate and the buffer to consume and absorb the kinetic energy of the vehicle, so that the vehicle stops moving. However, during the use of the wheel stopper, there is a situation where the wheel stopper is moved to a different position of the track. However, a buffer-type wheel stopper for railways in the prior art has the problem of being unable to retract, which makes the existing buffer-type wheel stopper for railways inconvenient to carry and move. For this reason, a buffer device is proposed. Utility Model Content

[0004] In view of this, an embodiment of the utility model hopes to provide a buffer device to solve or alleviate the technical problems existing in the prior art. By installing a first motor, the two fixed components can be driven to slide close to each other. Because the two fixed components can slide close to each other, the volume of the device can be shrunk after the two fixed components slide close to each other, so that the volume of the device can be shrunk, making it easier to carry and move.

[0005] The technical solution of the utility model embodiment is achieved as follows:

[0006] A buffer device comprises a fixed plate, on which a first motor and a second motor are fixedly mounted, two first threaded rods are fixedly mounted on the output end of the first motor, one end of the two first threaded rods are threadedly provided with a sliding square tube, one end of the two sliding square tubes are fixedly mounted with a fixed component, a rotating bar is fixedly mounted on the output end of the second motor, a sliding frame slidably matched with the rotating bar is fixedly mounted on one side of the two fixed components close to each other, a buffer component is rotatably provided on the fixed component, an electric push rod rotatably matched with the buffer component is rotatably provided on the fixed component, a second threaded rod is fixedly mounted on one end of the sliding frame, and two clamping components are threadedly provided at both ends of the second threaded rod.

[0007] Preferably: the buffer assembly includes a rotating plate, a sliding plate slidably arranged on one side of the rotating plate, two guide rods fixedly installed on one side of the sliding plate and passing through the rotating plate, and two springs fixedly installed between the sliding plate and the rotating plate. The installation of the guide rods can guide the sliding plate during the sliding process, thereby making the sliding plate slide more smoothly.

[0008] Preferably, the two springs are respectively sleeved on one end of the two guide rods, and the rotating plate is rotatably matched with the output end of the electric push rod. The installation of the springs plays a buffering role against the impact of the wheels.

[0009] Preferably: the fixed assembly includes a first fixed shell, a second fixed shell fixedly installed on one side of the first fixed shell, and a connecting plate fixedly installed on one side of the second fixed shell, one end of the connecting plate is rotatably matched with the rotating plate, and a limit seat is fixedly installed between the connecting plate and the second fixed shell, one side of which is in contact with one side of the rotating plate. The installation of the connecting plate facilitates the rotational matching of the fixed assembly and the rotating plate.

[0010] Preferably, the electric push rod and the second fixed shell are rotatably matched, and the clamping assembly includes a clamping frame and a clamping block fixedly installed inside the clamping frame. The installation of the clamping block facilitates the device to clamp the track.

[0011] Preferably, the clamping assembly is slidingly arranged between the first fixed shell and the second fixed shell, and two external threads are symmetrically arranged at both ends of the second threaded rod. The arrangement of the external threads facilitates the threaded cooperation between the second threaded rod and the clamping assembly.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model can drive two fixed components to slide close to each other through the installation of the first motor. Because the two fixed components can slide close to each other, the volume of the device can be shrunk after the two fixed components slide close to each other, making the device more convenient to carry and move after the volume is shrunk.

[0014] Second, the utility model can drive the clamping assembly to slide by installing the second motor, so that the sliding clamping assembly can clamp and fix the track, and after the clamping assembly clamps and fixes the track, the device can stop the wheel.

[0015] 3. The utility model drives the buffer assembly to rotate by installing an electric push rod, so that after the buffer assembly is rotated, when the wheel hits the buffer assembly, the force applied by the wheel to the buffer assembly is upward, so that the device obtains the force to move upward. When the device obtains the upward force, the friction between the clamping assembly and the track increases, which speeds up the device to stop the wheel.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, an embodiment of the utility model provides a buffer device, including: a fixed plate 1, on which a first motor 2 and a second motor 3 are fixedly mounted, two first threaded rods 4 are fixedly mounted on the output end of the first motor 2, one end of the two first threaded rods 4 are threadedly provided with a sliding square tube 5, one end of the two sliding square tubes 5 are fixedly mounted with a fixing component 6, a rotating bar 7 is fixedly mounted on the output end of the second motor 3, a sliding frame 8 slidably matched with the rotating bar 7 is fixedly mounted on the side of the two fixing components 6 close to each other, a buffer component 10 is rotatably provided on the fixing component 6, an electric push rod 11 rotatably matched with the buffer component 10 is rotatably provided on the fixing component 6, a second threaded rod 20 is fixedly mounted on one end of the sliding frame 8, and two clamping components 21 are threadedly provided at both ends of the second threaded rod 20.

[0027] In this embodiment, specifically: the buffer assembly 10 includes a rotating plate 12, a sliding plate 13 slidably arranged on one side of the rotating plate 12, two guide rods 14 fixedly installed on one side of the sliding plate 13 and penetrating the rotating plate 12, and two springs 15 fixedly installed between the sliding plate 13 and the rotating plate 12. When the electric push rod 11 is turned on, the electric push rod 11 drives the rotating plate 12 and the sliding plate 13 to rotate. When the sliding plate 13 has completed its rotation, the sliding plate 13 is in an inclined state. When the wheel hits the sliding plate 13, the sliding plate 13 obtains an upward force. The installation of the electric push rod 11 facilitates the device to obtain an upward force from the impact of the wheel.

[0028] In this embodiment, specifically: two springs 15 are respectively sleeved on one end of the two guide rods 14, and the rotating plate 12 is rotatably matched with the output end of the electric push rod 11. The installation of the springs 15 plays a role in buffering the impact force of the sliding plate 13.

[0029] In the present embodiment, specifically: the fixing assembly 6 includes a first fixing shell 16, a second fixing shell 17 fixedly mounted on one side of the first fixing shell 16, and a connecting plate 18 fixedly mounted on one side of the second fixing shell 17. One end of the connecting plate 18 is rotatably matched with the rotating plate 12. A limiting seat 19 is fixedly mounted between the connecting plate 18 and the second fixing shell 17, and one side of the limiting seat 19 is in contact with one side of the rotating plate 12. The installation of the limiting seat 19 can limit the rotating plate 12, so that when the rotating plate 12 is hit by the sliding plate 13, the electric push rod 11 is not easily damaged.

[0030] In this embodiment, specifically: the electric push rod 11 and the second fixed shell 17 are rotatably matched, and the clamping assembly 21 includes a clamping frame 22 and a clamping block 23 fixedly installed inside the clamping frame 22. The installation of the clamping block 23 can clamp the track, thereby facilitating the device to stop the wheel.

[0031] In this embodiment, specifically: the clamping assembly 21 is slidably arranged between the first fixed shell 16 and the second fixed shell 17, and two external threads are symmetrically arranged at both ends of the second threaded rod 20. The installation of the clamping assembly 21 facilitates clamping and fixing the track.

[0032] When the utility model is working: when the device needs to be retracted and moved, the first motor 2 is turned on, and the first motor 2 drives the first threaded rod 4 to rotate, and the rotation of the first threaded rod 4 drives the two sliding square tubes 5 and the fixed component 6 to slide close to each other. When the two fixed components 6 slide close to each other, the volume of the device is shrunk at this time;

[0033] When the device needs to clamp and fix the track, the second motor 3 is turned on, and the turning on of the second motor 3 drives the rotating bar 7, the sliding frame 8, and the second threaded rod 20 to rotate. The rotation of the second threaded rod 20 drives the two clamping assemblies 21 to slide close to each other. After the two clamping assemblies 21 slide close to each other, the two clamping assemblies 21 clamp and fix the track;

[0034] When the buffer component 10 rotates, when the buffer component 10 vertically stops the wheel, the wheel hits the buffer component 10, and the buffer component 10 obtains a forward force. However, when the electric push rod 11 is turned on, the electric push rod 11 drives the buffer component 10 to rotate. When the buffer component 10 completes rotation, the wheel hits the buffer component 10, and the buffer component 10 and the device obtain an upward force. When the device obtains the upward force, the friction between the clamping component 21 that clamps the wheel and the track increases.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
