[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] The present application provides a track 8 transport vehicle blocking device, which is arranged below the track 8 and includes: a first shaft 3, a gravity component 5, a second shaft 4, a mounting shell 1 and a rotating shaft component 2, wherein the mounting shell 1 has a mounting cavity 11, the rotating shaft component 2 is rotatably mounted on the shell, and the rotating shaft component 2 is at least partially located in the mounting cavity 11, the first shaft 3 and the second shaft 4 are arranged on the rotating shaft component 2, the first shaft 3 and the second shaft 4 are spaced apart on the rotating shaft component 2, and a preset angle is provided between the first shaft 3 and the second shaft 4, and the rotating shaft component 2 rotates so that one and only one of the first shaft 3 and the second shaft 4 is located in the mounting cavity 11,

[0037] The gravity component 5 is arranged at an end of the first shaft 3 away from the rotating shaft component 2 .

[0038] Specifically, Figures 1 to 5 As shown, the mounting housing 1 is disposed below the track 8 , and the mounting housing 1 has a mounting cavity 11 facing upwards for mounting the rotating shaft component 2 , and the rotating shaft component 2 is rotatable in the mounting cavity 11 .

[0039] One end of the first shaft 3 is connected to the shaft component 2, and the other end of the first shaft 3 is installed with a gravity component 5, which has a certain weight so that the first shaft 3 drives the shaft component 2 to rotate. The first shaft 3 is arranged in the installation cavity 11.

[0040] One end of the second shaft 4 is connected to the rotating shaft component 2, and the other end of the second shaft 4 extends out of the installation cavity 11 to stop the vehicle. Or it can be understood that the other end of the second shaft 4 is located outside the installation cavity 11 to stop the vehicle. When the vehicle is reversed or running away, that is, when the vehicle moves from the back to the front, the vehicle impacts the second shaft 4 to make the second shaft 4 rotate upward, and the first shaft 3 has a downward rotation trend. Since the first shaft 3 is in contact with the inner wall surface of the installation cavity 11 at this time, the first shaft 3 cannot continue to rotate downward, and then the second shaft 4 cannot rotate, thereby stopping the vehicle, thereby preventing the vehicle from reversing or running away.

[0041] Only one of the first shaft 3 and the second shaft 4 can be in the installation cavity 11, that is, when passing in one direction, that is, moving from front to back, the vehicle presses the second shaft 4 to rotate downward, and the first shaft 3 rotates upward, so that the vehicle can pass safely. After the vehicle passes, the first shaft 3 where the gravity component 5 is located rotates to rotate the first shaft 3 again into the installation cavity 11, and then the end of the second shaft 4 away from the first shaft 3 rotates upward and extends out of the installation cavity 11 to restore the vehicle blocking state.

[0042] One-way traffic:

[0043] When the vehicle moves from front to back (i.e., in the normal direction), the vehicle will press the second shaft 4, causing it to rotate downward. Due to the preset angle relationship between the first shaft 3 and the second shaft 4, when the second shaft 4 rotates downward, the first shaft 3 will rotate upward accordingly, thereby enabling the vehicle to pass through the device.

[0044] Vehicle is moving in reverse or running away: When the vehicle moves from back to front (i.e., in the direction of moving in reverse or running away), one end of the second shaft 4 will extend out of the installation cavity 11 to stop the vehicle. When the vehicle hits the second shaft 4, the second shaft 4 will try to rotate upward, but at this time, due to the contact between the first shaft 3 and the inner wall of the installation cavity 11, the first shaft 3 cannot continue to rotate downward. That is, due to the connection between the first shaft 3 and the second shaft 4, the second shaft 4 cannot continue to rotate, thereby effectively preventing the vehicle from moving in reverse or running away. Avoid the safety hazards caused by the vehicle moving in reverse or running away, and improve the traffic efficiency. A gravity component 5 is provided in the device to ensure that the first shaft 3 is in the installation cavity 11 under normal circumstances. When the vehicle passes normally, the gravity component 5 causes the first shaft 3 to rotate and return to the installation cavity 11, thereby maintaining the stable operation of the device.

[0045] The present application provides a vehicle blocking device for rail 8 transportation, which is provided with a mounting shell 1, and a mounting cavity 11 is provided in the mounting shell 1 for installing a rotating shaft component 2. When the vehicle is passing in one direction, that is, when it moves from front to back, the vehicle presses the second shaft 4 to make the second shaft 4 rotate downward, and the first shaft 3 rotates upward at this time, so that the vehicle can pass safely, and one-way passage does not require manual operation. When the vehicle is reverse or running away, that is, when the vehicle moves from back to front, one end of the second shaft 4 extends out of the mounting cavity 11 to block the vehicle, and the vehicle impacts the second shaft 4 to make the second shaft 4 rotate upward, and the first shaft 3 rotates downward. Since the first shaft 3 is in contact with the inner wall surface of the mounting cavity 11 at this time, the first shaft 3 cannot continue to rotate downward at this time, and the second shaft 4 cannot rotate, so that the vehicle stops, and the vehicle is prevented from reversing or running away, so that the vehicle passes and improves the traffic efficiency, and avoids running away accidents. By providing a gravity component 5, the first shaft 3 is placed in the mounting cavity 11 under the action of gravity. When the vehicle passes normally, the gravity component 5 makes it easy for the first shaft 3 to rotate back to the mounting cavity 11.

[0046] At the same time, the present application adopts the first shaft 3, the second shaft 4 and the gravity component 5 to realize one-way passage of vehicles, which has a simple structure, reduces the cost of production and manufacturing, and improves the stability of the use of the vehicle blocking device.

[0047] In some embodiments, a preset angle A is formed between the first axis 3 and the second axis 4 , and 120°≤A≤150°.

[0048] When the preset angle A reaches or exceeds 120°, it can be ensured that the relative rotation between the first shaft 3 and the second shaft 4 will not hinder the vehicle when the vehicle passes normally. This is because within this angle range, when the second shaft 4 is pressed by the vehicle and rotates downward, the first shaft 3 will rotate upward accordingly, leaving enough space for the vehicle to pass.

[0049] The upper limit of the preset angle A is set to 150° to prevent the relative rotation between the first shaft 3 and the second shaft 4 from being too violent when the vehicle is running in reverse or running away, resulting in damage to the device or failure to effectively block the vehicle. Within this angle range, when the vehicle hits the second shaft 4, the first shaft 3 and the gravity component 5 will be restricted by the inner wall of the installation cavity 11 and cannot continue to rotate downward, thereby ensuring that the second shaft 4 can stably extend out of the installation cavity 11 to block the vehicle.

[0050] Furthermore, the mounting housing 1 is provided with a first slot 111 corresponding to the first shaft 3 and a second slot 112 corresponding to the second shaft 4 , and the shaft component 2 rotates to allow the first shaft 3 to enter and exit the first slot 111 or the second shaft 4 to enter and exit the second slot 112 .

[0051] Specifically, Figures 1 to 5 As shown, the first groove 111 corresponds to the first shaft 3, so that the first shaft 3 can rotate within a certain range, guide and limit the first shaft 3, and when the vehicle passes normally, the first shaft 3 rotates upward or downward due to the linkage relationship with the second shaft 4, and the first groove 111 guides and limits the first shaft 3. The second groove 112 corresponds to the second shaft 4, and the second shaft 4 can rotate up and down in the mounting cavity 11 of the mounting housing 1. In the case of a vehicle going in reverse or running away, one end of the second shaft 4 extends out of the second groove 112 of the mounting cavity 11 to stop the vehicle.

[0052] In some embodiments, the track 8 transport vehicle blocking device further includes a buffer pad 6 , the gravity component 5 includes a gravity hammer, the buffer pad 6 is disposed in the first groove 111 , and the shaft component 2 rotates to allow the gravity hammer to impact or move away from the buffer pad 6 .

[0053] Specifically, Figures 1 to 5 As shown, the buffer pad 6 absorbs and disperses the energy generated by the impact of the gravity hammer. When the gravity hammer impacts the buffer pad 6 due to the rotation of the shaft component 2, the buffer pad 6 can reduce the vibration and noise caused by the impact, while protecting the mounting housing 1 and the shaft component 2 from damage, thereby increasing the service life of the device.

[0054] Furthermore, a buffer pad 6 may also be provided in the second groove 112 to buffer the rotation of the second shaft 4, and the buffer pad 6 absorbs energy during the buffering process. When the second shaft 4 rotates upward, the buffer pad 6 returns to its original state while giving the second shaft 4 an upward force so that the second shaft 4 can easily return to its original state.

[0055] In some embodiments, the gravity hammer is shaped like at least a portion of a truncated cone, a cylinder, or a sphere.

[0056] Specifically, Figures 1 to 5As shown, when the truncated cone-shaped gravity hammer impacts, due to its large bottom diameter, it can provide a larger contact area, thereby dispersing the impact force, reducing the possibility of single-point force, reducing the impact stress on the mounting housing 1 or other contact parts, and improving the durability of the device. The cylindrical gravity hammer is easy to process and manufacture, reducing the cost of the device.

[0057] The spherical gravity hammer has the same curvature in all directions during impact, which can provide uniform gravity and impact force distribution. This design helps to reduce the local stress concentration generated during the impact process and improve the durability and safety of the device.

[0058] In some embodiments, the buffer pad 6 includes a wear-resistant layer 61 and a buffer layer 62. One end of the buffer layer 62 is connected to the inner wall surface of the first groove 111, and the other end of the buffer layer 62 is connected to the wear-resistant layer 61.

[0059] The material of the buffer layer 62 is any one of foamed polypropylene or pearl cotton, and the material of the wear-resistant layer 61 is at least one of rubber and polyurethane epoxy resin. For example, the wear-resistant layer 61 is any one of rubber and polyurethane epoxy resin, or the wear-resistant layer 61 is a multi-layer structure, for example, the first layer is rubber, the second layer is polyurethane, and the third layer is epoxy resin.

[0060] Specifically, Figures 1 to 5 As shown, the wear-resistant layer 61 is disposed above the buffer layer 62 , and a structural adhesive may be coated between the wear-resistant layer 61 and the buffer layer 62 to connect the wear-resistant layer 61 and the buffer layer 62 .

[0061] The wear-resistant layer 61 is made of at least one of rubber, polyurethane and epoxy resin.

[0062] Furthermore, the wear-resistant layer 61 may be made of rubber, or a mixture of rubber and polyurethane, or a mixture of rubber, polyurethane and epoxy resin, etc., so as to improve the wear resistance of the wear-resistant layer 61 and thereby increase the service life of the buffer pad 6 .

[0063] The buffer layer 62 is made of either foamed polypropylene or pearl cotton to absorb the impact of the gravity component 5 and reduce the noise.

[0064] In some embodiments, the track 8 transport vehicle blocking device further includes a magnetic component, the gravity hammer is made of ferromagnetic material or paramagnetic material, and the magnetic material is disposed in the first groove 111 and connected to an end of the buffer layer 62 away from the wear-resistant layer 61 .

[0065] Specifically, Figures 1 to 5As shown, the position of the gravity hammer corresponding to the first slot 111 can be provided with a mounting hole for mounting a magnetic component, and the gravity hammer is made of a ferromagnetic material or a paramagnetic material, so that when the gravity hammer is in use, the gravity hammer and the magnetic component always have a magnetic adsorption effect, thereby making it easy for the gravity hammer to return to the first slot 111.

[0066] When the gravity hammer approaches the first slot 111 , due to the magnetic field generated by the magnetic component, the gravity hammer is subjected to a magnetic force directed toward the first slot 111 , so that the gravity hammer remains stable during movement and automatically aligns and returns when approaching the first slot 111 .

[0067] In some embodiments, the rail 8 transport vehicle blocking device also includes a limit member 7, which is connected to the inner wall of the mounting shell 1, and is arranged in the first groove 111 to limit the first axis 3, wherein the limit member 7 is provided with a limit groove 71 that matches the first axis 3 on the side facing the first axis 3.

[0068] That is, the lower end of the limiting member 7 is provided with a limiting groove 71 corresponding to the first shaft 3, so as to increase the contact area between the limiting member 7 and the first shaft 3 when limiting, and the first shaft 3 cannot continue to rotate upward after extending into the limiting groove 71, and the shaking of the first shaft 3 in the left and right directions is avoided, thereby improving the stability of the first shaft 3 when rotating. Furthermore, the number of the limiting members 7 can be multiple, and the multiple limiting members 7 are arranged at intervals in the front-to-back direction.

[0069] In some embodiments, the shaft component 2 includes a shaft 21, a spring 22, a boss 23 disposed on the shaft 21, and a handle 24. The shaft 21 is rotatably disposed on the mounting housing 1, and the shaft 21 is at least partially disposed in the mounting cavity 11. The handle 24 is disposed outside the mounting cavity 11 and connected to the shaft 21. The spring 22 is disposed on the shaft 21 and connected to the boss 23. The spring 22 is connected to the mounting housing 1 to rotate the first shaft 3 in the direction of extending into the mounting cavity 11. The boss 23 is fixedly connected to the shaft 21.

[0070] The handle 24 is connected to the rotating shaft 21, and the rotating shaft 21 is rotatably disposed in the mounting cavity 11. For example, the left and right ends of the rotating shaft 21 are provided with bearings to be mounted on the mounting housing 1. One end of the spring 22 is connected to the boss 23, and the other end of the spring 22 is connected to the mounting housing 1. The spring 22 is sleeved on the rotating shaft 21 and connected to the boss 23. The spring 22 enables the rotating shaft 21 to return to an initial position or a predetermined position after being acted upon by an external force.

[0071] The handle 24 is arranged outside the installation cavity 11 and connected to the rotating shaft 21. The handle 24 is an interface for the user to operate the rotating shaft component 2. By rotating the handle 24, the rotating shaft 21 and the first shaft 3 and the second shaft 4 connected thereto can be driven to rotate, so that vehicles that need to go in reverse under special circumstances can pass through the vehicle blocking device.

[0072] When the user rotates the handle 24, the handle 24 drives the shaft 21 to rotate in the mounting housing 1. The rotational movement of the shaft 21 is transmitted to the spring 22 through the boss 23, and the spring 22 expands and contracts accordingly according to the movement of the boss 23. When the external force disappears, the spring 22 uses its own restoring force to push the boss 23 and the shaft 21 to rotate in opposite directions, so that the shaft component 2 returns to the initial position or the predetermined position.

[0073] The introduction of the spring 22 enables the shaft component 2 to have a self-reset function. Even if it is deflected by an external force, it can automatically return to a predetermined position under the restoring force of the spring 22. The provision of the handle 24 enables the user to conveniently operate the shaft component 2, and the rotation operation can be completed without entering the installation cavity 11. At the same time, the compact design of the components such as the shaft 21, the spring 22, the boss 23 and the handle 24 makes the overall structure of the shaft component 2 compact and easy to install and maintain.

[0074] In some embodiments, there are multiple second shafts 4, which are arranged at intervals in the axial direction of the rotating shaft 21. The second shafts 4 are arranged at intervals in the axial direction of the rotating shaft 21, which improves the stability of the second shafts 4 when blocking the vehicle, thereby improving the stability of the device when blocking the vehicle.

[0075] Furthermore, a baffle that seals the installation cavity 11 may be provided at the upper end of the device to prevent debris from entering the installation cavity 11. The above is a detailed introduction to the one provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
