Referring to fig. 1, 2, 3 and 4, the wheel stopper device includes an operation table 10, a first driving lever 21, a second driving lever 22, and a stopper 23.
The operation table 10 has a table structure, and a top plan view of the illustrated position is an operation plane of the operation table 10. The console 10 has a track for the passage of train wheels, and the first predetermined position is located on the top surface of the track, so that the stop block 23 provided on the console 10 can be translated to the top surface of the track, thereby locking the wheels on the track. The operation platform 10 may be, for example, a transfer platform, the transfer platform has a track for passing the train wheel, and the first driving rod 21 and the second driving rod 22 are disposed on the surface of the transfer platform to drive the blocking block 23 to move to the top surface of the track, so as to block the wheel.
The first drive lever 21 and the second drive lever 22 are both arranged parallel to the plane of the console 10. Illustratively, the first driving rod 21 and the second driving rod 22 are both cylindrical rod structures, and to ensure that the first driving rod 21 and the second driving rod 22 have certain strength and good portability, the first driving rod 21 and the second driving rod 22 may be rod-shaped structures with hollow interiors, and the material of the first driving rod 21 and the second driving rod 22 may be, for example, steel.
One end of the first driving lever 21 is connected to the stopper 23, and the other end of the first driving lever 21 is hinged to the second driving lever 22 through a first hinge shaft 211.
Illustratively, the left end of the first drive rod 21 in the illustrated position may be removably coupled to the stop 23 to facilitate replacement of the stop 23. For example, the first driving rod 21 and the stopper 23 may be screwed, or the first driving rod 21 and the stopper 23 may be engaged. Of course, in some other examples where it is not necessary to disassemble the stop block 23, the stop block 23 may be welded to the first driving rod 21 to improve the connection strength between the stop block 23 and the first driving rod 21.
Illustratively, the right end of the first driving lever 21 in the illustrated position is provided with a first hinge hole, correspondingly, one end of the second driving lever 22 is provided with a second hinge hole, and the first hinge shaft 211 is inserted into the first hinge hole and the second hinge hole, so that the first driving lever 21 and the second driving lever 22 can rotate around the first hinge shaft 211. Referring to fig. 1, the center line of the first hinge shaft 211 is perpendicular to the plane of the console 10, so that the first driving lever 21 and the second driving lever 22 rotate in a plane parallel to the plane of the console 10.
The first driving rod 21 is also hinged with the operation table 10 through a second hinge shaft 221, and the center line of the second hinge shaft 221 is perpendicular to the plane of the operation table 10. Illustratively, the first driving rod 21 is further provided with a third hinge hole, and the second hinge shaft 221 is disposed in the third hinge hole, so that the first driving rod 21 can also rotate around the second hinge shaft 221.
In the position shown, the second driving lever 22 is used to drive the right end of the first driving lever 21 to rotate, so that the first driving lever 21 rotates around the second hinge shaft 221, and the first driving lever 21 drives the blocking block 23 to rotate to the first preset position. It should be noted that the first predetermined position is located on the top surface of the rail, and when the stop block 23 is located at the top end of the rail, the stop block 23 can block the wheels on the rail.
The embodiment of the invention provides a wheel stopping device, which comprises an operation table 10, a first driving rod 21, a second driving rod 22 and a blocking block 23; the operation platform 10 is provided with an operation plane, the operation plane is provided with a track for the wheel to pass through, the first driving rod 21 and the second driving rod 22 are both arranged in parallel with the operation plane, the stop block 23 is positioned on the operation plane, one end of the first driving rod 21 is connected with the stop block 23, the other end of the first driving rod 21 is hinged with the second driving rod 22 through a first hinge shaft 211, the first driving rod 21 is further hinged with the operation platform 10 through a second hinge shaft 221, and the central lines of the first hinge shaft 211 and the second hinge shaft 221 are both vertical to the operation plane; the second driving rod 22 is used for driving the first driving rod 21 to rotate around the second hinge shaft 221, so that the first driving rod 21 drives the blocking block 23 to rotate to a first preset position, and the first preset position is located on the top surface of the track. Compared with the prior art in which the wheel stopper is placed in a manual operation mode, the embodiment of the invention drives the second driving rod 22 to move, so that the second driving rod 22 drives the first driving rod 21 to rotate around the second hinge shaft 221, and the first driving rod 21 drives the blocking block 23 to rotate to the top surface of the track, so that the wheels are blocked, the operation process is simplified, and the manual work is saved.
Furthermore, the wheel is blocked by the wheel stopping device provided by the embodiment of the invention, and the wheel stopping device is beneficial to avoiding personal accidents when a wheel stopper is manually placed, so that the operation safety is improved.
Optionally, a first distance L1 is provided between the end of the first driving lever 21 connected to the stopper 23 and the second hinge shaft 221, a second distance L2 is provided between the end of the first driving lever 21 hinged to the second driving lever 22 and the second hinge shaft 221, and the first distance L1 is greater than the second distance L2, so as to increase the driving effect of the second driving lever 22 and reduce the overall size of the wheel stopper device.
Illustratively, in the illustrated position, the left end of the primary drive lever 21 is connected to the stop 23 and the right end of the primary drive lever 21 is connected to the secondary drive lever 22. The first distance L1 is greater than the second distance L2, the first distance L1 may be 800mm to 900mm, and the second distance L2 may be 150mm to 250 mm. For example, first distance L1 may be 900mm, and correspondingly, second distance L2 may be 150mm, and the ratio of first distance L1 to second distance L2 is 6, so that when first drive lever 21 rotates at an angle about second hinge shaft 221, the ratio of the arc length of rotation of the right end of first drive lever 21 to the arc length of rotation of the left end of first drive lever 21 is also 6. It can be seen that the first distance L1 is greater than the second distance L2, and when the left end of the first driving rod 21 driven by the second driving rod 22 rotates by a relatively small arc length, the right end of the first driving rod 21 rotates by a relatively large arc length, so that the movable range of the blocking block 23 is increased, the overall size of the wheel stopping device is reduced, and the occupied area of the wheel stopping device is reduced.
Optionally, the length of the second driving rod 22 is greater than the length of the first driving rod 21, so that the operator can have a certain safety distance from the stop 23, thereby improving the safety of the operation.
Illustratively, the length of the first driving rod 21 may be 950mm to 1150mm, and the length of the second driving rod 22 may be 1900mm to 2100mm, for example, the length of the first driving rod 21 may be 1000mm, and correspondingly, the second distance L2 may be 2000mm, so as to further increase the distance between the operator and the stop block 23, and further improve the safety of the operation during the process that the stop block 23 is jammed with the wheel.
Optionally, the device further comprises a guide block 30, the guide block 30 is disposed on the operation table 10, the guide block 30 has a sliding channel, the second driving rod 22 is slidably disposed in the sliding channel, and an extending direction of the sliding channel is parallel to a plane of the operation table 10.
Illustratively, the guide block 30 may be a block-shaped structure, the sliding channel may be a through hole, and the extending direction of the sliding channel is parallel to the plane of the operation table 10, that is, the center line of the sliding channel is parallel to the plane of the operation table 10, so that the second driving rod 22 can move in the plane parallel to the operation table 10.
It should be noted that the cross-sectional area of the sliding channel is larger than the cross-sectional area of the second driving rod 22, so that the second driving rod 22 can rotate in the sliding channel at a certain angle.
Optionally, the device further includes a first limiting block 41, the first limiting block 41 is connected to the console 10, and the first limiting block 41 is configured to prevent the first driving rod 21 from continuing to rotate when the first driving rod 21 drives the blocking block 23 to rotate to the first preset position.
Referring to fig. 2, the first stopper 41 may be welded to the operation table 10, and the first stopper 41 may be disposed above the illustrated position of the first driving lever 21. When an operator drives the second driving rod 22 to move towards the lower side of the illustrated position, the second driving rod 22 simultaneously rotates clockwise, and the second driving rod 22 drives the first driving rod 21 to rotate clockwise around the second hinge shaft 221 until the blocking block 23 is driven to rotate to the first preset position, that is, when the blocking block 23 rotates to the top surface of the track, the first driving rod 21 abuts against the first limiting block 41, so that the first driving rod 21 is prevented from rotating continuously.
With continued reference to fig. 2, the extending direction of the first driving rod 21 is perpendicular to the extending direction of the track, so that the blocking piece 23 is kept at a position perpendicular to the extending direction of the track, thereby further improving the blocking effect of the blocking piece 23.
It should be noted that the first stopper 41 can also be used to limit the rotation of the second driving rod 22, so as to limit the movement of the stopper 23. For example, the first stopper 41 may be disposed above the second driving lever 22 in the illustrated position, so that the second driving lever 22 cannot move upward any further, thereby preventing the first driving lever 21 from rotating further.
Optionally, the device further includes a second limiting block 42, the second limiting block 42 is connected to the operating platform 10, and the second driving rod 22 is further configured to drive the first driving rod 21 to rotate around the second hinge shaft 221, so that the first driving rod 21 drives the blocking block 23 to rotate to a second preset position; the second stopper 42 is used for preventing the first driving rod 21 from continuing to rotate when the first driving rod 21 drives the blocking piece 23 to rotate to the second preset position.
Referring to fig. 3, the second stopper 42 may also be welded to the console 10, the second stopper 42 may be disposed below the illustrated position of the first driving lever 21, and further, the second stopper 42 may be disposed on the left side of the illustrated position of the second driving lever 22. When the operator drives the second driving rod 22 to move upward from the illustrated position, the second driving rod 22 simultaneously rotates counterclockwise, and the second driving rod 22 drives the first driving rod 21 to rotate counterclockwise around the second hinge shaft 221 until the blocking block 23 is driven to rotate to the second preset position, that is, when the blocking block 23 rotates to the surface of the operation table 10, the first driving rod 21 abuts against the second limiting block 42, so that the first driving rod 21 is prevented from continuing to rotate. At this time, the stopper 23 is prevented from colliding with the second driving lever 22 due to the second stopper 42.
It should be noted that the second stopper 42 can also be used to limit the rotation of the second driving rod 22, so as to limit the movement of the stopper 23. For example, the second stopper 42 may be disposed below the second driving rod 22 in the illustrated position, so that the second driving rod 22 cannot move downward further, thereby preventing the first driving rod 21 from rotating further.
Optionally, the barrier 23 comprises an elastic layer and a rigid layer 232 sandwiched between the elastic layers.
Referring to fig. 5, the stopper 23 may have a hexahedral structure, and the stopper 23 may have a three-layer structure stacked, wherein the stopper 23 includes a first elastic layer 231 for contacting the top surface of the rail, a second elastic layer 233 for contacting the wheel, and a rigid layer 232 disposed between the first elastic layer 231 and the second elastic layer 233, and the rigid layer 232 is used to support the stopper 23 and improve the strength of the stopper 23.
In this embodiment, a threaded hole may be formed at one end of the blocking block 23, and correspondingly, a through hole may be formed at one end of the first driving rod 21, so that the blocking block 23 and the first driving rod 21 are threadedly connected by a threaded fastener such as a bolt.
It should be noted that, the blocking block 23 may have a certain distance from the surface of the console 10, so as to avoid friction between the blocking block 23 and the surface of the console 10 when the blocking block 23 moves, thereby causing movement blockage of the blocking block 23, and further being beneficial to avoiding abrasion of the first elastic layer 231 of the blocking block 23, thereby prolonging the service life of the blocking block 23.
Optionally, the elastic layer is a rubber layer, and the rigid layer 232 is a steel plate.
In this embodiment, the first elastic layer 231 is a rubber layer, which is beneficial to increase the friction between the stopper 23 and the rail, so as to further prevent the stopper 23 from moving relative to the rail. Similarly, the second elastic layer 233 is a rubber layer, which is beneficial to increase the friction force between the stopper 23 and the wheel, so as to further improve the braking capability of the stopper 23. Furthermore, the surface of the rubber material has good corrosion resistance and heat resistance, which is beneficial to further prolonging the service life of the barrier block 23. In this embodiment, the rigid layer 232 steel plate is beneficial to improving the strength of the blocking block 23, thereby further improving the performance of the wheel stopping device.
Optionally, a handle 50 is further included, and the handle 50 is connected to the second driving rod 22 so as to drive the second driving member to move through the handle 50, thereby improving the operability of the wheel stopping device.
Referring to fig. 1, the handle 50 may have a rod-shaped structure, one end of the handle 50 is connected to the second driving rod 22, and the other end of the handle 50 has a ball for an operator to grasp. Further, the handle 50 extends perpendicularly to the second driving lever 22, so that the operator is prevented from lowering the center of gravity for operation, thereby further improving the operability of the wheel stopper device.
Optionally, the surfaces of the first driving rod 21 and the second driving rod 22 are further provided with an anti-rust layer so as to improve the service life of the wheel stopping device.
In a possible implementation, the rust-proof layer on the surface of the first driving rod 21 and the second driving rod 22 may be a rust-proof paint or a rust-proof oil film, so as to further improve the service life of the wheel stopping device.
