[0027] The working principle and beneficial effects of the utility model are:

[0028] In the utility model, a frame is designed, which serves as the basic support of the entire car blocker, provides a stable and solid installation platform, and ensures that all components can be safely and reliably fixed and operated. The rotating shaft located on the frame is the core rotating component of the car blocker, which can rotate freely and provide a resistance basis for the speed reduction after the hook moves. The installation position of the rotating shaft ensures that the hook has enough space when moving to adapt to vehicles and parking areas of different sizes. The hook is a component that directly contacts the vehicle and is designed to be movable. This feature enables it to adjust its position as needed and contact the fixed point of the vehicle in the best way to achieve the blocking function. When the vehicle needs to be intercepted, the hook moves so that the position of the hook can be hung on the vehicle. The design of the hook being located above the rotating shaft helps to reduce the interference of related structures when the vehicle stops, ensuring the car blocking effect. The limit rope is the key link connecting the rotating shaft and the tail of the hook. Through this connection, when the hook is hung on the vehicle, its power is transmitted to the rotating shaft through the limit rope. At this time, the rotation speed of the rotating shaft gradually decreases under the action of external force. The length and strength of the limit rope are reasonably designed to ensure the safety and control accuracy during operation. At the same time, it can also limit the moving range of the hook in an emergency situation to avoid potential damage caused by the vehicle moving too far. Compared with the mechanical car blocker of the prior art, the design of the limit rope and the rotating shaft allows the trolley in the coal mine tunnel to gradually stop under the action of external force, rather than stop suddenly, so that the material on the trolley is reduced from being thrown out due to the action of inertia, reducing the labor intensity of the operator. During installation, the position of the rotating shaft needs to be below the ground of the tunnel, and the position of the hook needs to be above the ground of the tunnel, so as to better meet the vehicle interception requirements of the tunnel. In summary, the mechanical car blocker realizes effective blocking of vehicles through the coordinated work of the frame, the rotating shaft, the hook and the limit rope. It is particularly suitable for the coal mine tunnel environment. When the trolley is full of materials and slips, it can stop slowly, ensuring that the material is thrown out as little as possible when intercepting the vehicle, reducing the labor intensity of the operator, while ensuring the cleanliness of the tunnel and reducing potential sources of danger.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a mechanical car arrester, including a frame 1, a rotating shaft 2 rotatably set on the frame 1, a hook 3 movably set relative to the frame 1, the position of the hook 3 is higher than the rotating shaft 2, one end of the limiting rope 4 is connected to the rotating shaft 2, and the other end is connected to the tail of the hook 3.

[0039] In this embodiment, a frame 1 is designed, which serves as the basic support of the entire car blocker, provides a stable and sturdy installation platform, and ensures that all components can be safely and reliably fixed and operated. The rotating shaft 2 located on the frame 1 is the core rotating component of the car blocker. It can rotate freely and provide a resistance basis for the speed reduction after the hook 3 moves. The installation position of the rotating shaft 2 ensures that the hook 3 has enough space when moving to adapt to vehicles and parking areas of different sizes. The hook 3 is a component that directly contacts the vehicle and is designed to be mobile. This feature enables it to adjust its position as needed and contact the fixed point of the vehicle in the best way to achieve the blocking function. When the vehicle needs to be intercepted, the hook 3 swings so that the position of the hook 3 can be hung on the vehicle. The design of the hook 3 being located above the rotating shaft 2 helps to reduce the interference of related structures when the vehicle stops, ensuring the blocking effect. The limit rope 4 is the key link connecting the rotating shaft 2 and the tail of the hook 3. Through this connection, when the hook 3 is hung on the vehicle, its power is transmitted to the rotating shaft 2 through the limit rope 4. At this time, the rotation speed of the rotating shaft 2 is gradually reduced under the action of external force. The length and strength of the limit rope 4 are reasonably designed to ensure the safety and control accuracy during operation. At the same time, it can also limit the moving range of the hook 3 in an emergency situation to avoid potential damage caused by the vehicle moving too far. Compared with the mechanical car blocker of the prior art, the design of the limit rope 4 and the rotating shaft 2 allows the trolley in the coal mine tunnel to gradually stop under the action of external force, rather than stop suddenly, so that the material on the trolley is reduced from being thrown out due to the action of inertia force, and the labor intensity of the operator is reduced. During installation, the position of the rotating shaft 2 needs to be below the ground of the tunnel, and the position of the hook 3 needs to be above the ground of the tunnel, so as to better meet the vehicle interception requirements of the tunnel. In summary, the mechanical car blocker realizes effective blocking of the vehicle through the coordinated work of the frame 1, the rotating shaft 2, the hook 3 and the limit rope 4, and is particularly suitable for the coal mine tunnel environment. When the trolley is full of materials, it can stop slowly when slipping occurs, ensuring that the material is thrown out as little as possible when intercepting the vehicle, reducing the labor intensity of the operator, while ensuring the cleanliness of the tunnel and reducing potential sources of danger.

[0040] Furthermore, it also includes a swing driving member 5, which is arranged on the frame 1 and drives the hook 3 to swing. The damping member 6 is arranged on the frame 1 and abuts against one end of the rotating shaft 2 to reduce the rotation speed of the rotating shaft 2.

[0041] In this embodiment, a swing drive 5 is designed to directly drive the hook 3 to move, and the end of the swing drive 5 is made of magnetic material, which is convenient for the hook 3 to be adsorbed and fixed on the swing drive 5, so that the hook 3 can swing. This design not only makes the swing of the hook 3 more accurate and controllable, but also ensures that the hook 3 can quickly respond to the control command of interception, complete the rapid conversion from standby to blocking, and improve the response speed and automation level of the car blocker. The damping member 6 is in contact with one end of the rotating shaft 2, and its function is to effectively control and reduce the rotation speed of the rotating shaft 2. This design can ensure that the rotating shaft 2 and the connected hook 3 slow down smoothly during the movement or rotation process, reduce the impact force and noise, and improve the overall comfort and safety of use. In summary, the mechanical car blocker enhances the response speed of the car blocker through the design of the swing drive 5 and the damping member 6, while reducing the possibility of materials on the vehicle being thrown out during the vehicle stopping process.

[0042] Furthermore, the damping element 6 is a rubber skin.

[0043] In this embodiment, rubber skin is used as the damping member 6. As a common and efficient damping material, the rubber skin is arranged on the frame 1 and is close to one end of the rotating shaft 2. The characteristics of the rubber material determine that it can well absorb the vibration and impact generated by the rotating shaft 2 during the rotation process, and consume energy through its own elastic deformation, thereby achieving the purpose of reducing the rotation speed, reducing noise and protecting the mechanical structure. Compared with hard materials, when the rubber skin is used as the damping member 6 and contacts the metal rotating shaft 2, it can significantly reduce wear and reduce the noise generated by friction during long-term use, thereby improving the quietness and durability of the car arrester. The rubber skin is easy to install and replace as the damping member 6. Once it is severely worn or aged, the maintenance cost is low and the operation is simple. No complicated machining or special tools are required, which improves the maintenance efficiency of the car arrester. In summary, the mechanical car arrester not only realizes the effective control of the rotation speed of the rotating shaft 2 by using rubber skin as the damping member 6, but also takes into account the comprehensive advantages of noise reduction, shock absorption, wear resistance and easy maintenance.

[0044] Furthermore, it also includes a brake disc 7, which is arranged on the rotating shaft 2, and a brake 8 is arranged on the frame 1, and the brake disc 7 extends into the brake 8.

[0045] In this embodiment, a brake disc 7 is added to the rotating shaft 2, which is a key dynamic braking element. The brake disc 7 rotates coaxially with the rotating shaft 2, and its position design is intended to work in conjunction with the brake 8 introduced later to achieve fast and accurate braking control of the rotating shaft 2. The brake 8 is installed on the frame 1 and can accommodate the extended part of the brake disc 7. When braking is required, the brake 8 acts on the brake disc 7 by mechanical, hydraulic or electromagnetic means to generate friction, slow down or even stop the rotation of the rotating shaft 2, thereby achieving instant control of the swinging action of the hook 3. The addition of the brake system significantly improves the safety factor of the car arrester, especially in an emergency, it can respond quickly and immediately fix the position of the hook 3 to avoid accidents. The use of the brake 8 and the brake disc 7 enables the operator to control the action of the hook 3 more accurately, whether it is starting, stopping or maintaining a specific position, it can be more accurate. The design of the brake disc 7 and the brake 8 needs to consider wear-resistant materials and reasonable wear compensation mechanisms to ensure long-term stable operation, and facilitate regular inspection and maintenance to extend the service life. The addition of the brake 8 and the brake disc 7 is mainly used to supplement the deceleration resistance of the damping element 6, and the overall service life of the equipment is improved through the design of the brake 8. In summary, the mechanical car arrester not only enhances the braking efficiency of the system through the addition of the brake disc 7 and the brake 8, but also improves the overall controllability and safety, so that the car arrester can achieve emergency stop of the vehicle under special safety conditions.

[0046] Furthermore, it also includes a locking member 9, which is slidably arranged on the frame 1, and acts on or cancels the action on the rotating shaft 2 after sliding, so as to lock the rotating shaft 2.

[0047] In this embodiment, the locking member 9 slidingly arranged on the frame 1 is a key component for controlling whether the rotating shaft 2 can rotate. This design enables the operator or the automatic control system to easily lock or unlock the rotating shaft 2 through a simple sliding action as needed. When the locking member 9 slides to the action position, it will directly or indirectly contact the rotating shaft 2, and prevent the rotation of the rotating shaft 2 by physical restriction, thereby fixing the position of the hook 3, ensuring that the rotating shaft 2 will not rotate due to accidents when the car blocker is not required to work, or during maintenance and overhaul, thereby improving safety and maintenance convenience. The addition of the locking member 9 gives the car blocker higher flexibility and safety. When not in use, by locking the rotating shaft 2, accidental movements caused by factors such as wind force and external force impact can be effectively prevented, and the hook 3 is always in the standby position before use. At the same time, this design is also convenient for rapid locking or unlocking in an emergency, improving the emergency response capability of the system. In summary, the mechanical car blocker, through the integration of the locking member 9, not only enhances the control accuracy and safety of the rotating shaft 2, but also improves the maintenance convenience of the equipment and the reliability of the overall system.

[0048] Furthermore, it also includes a swing baffle 10, which is swingably set on the frame 1 to receive the materials thrown out when the vehicle is blocked. One end of the traction rope 11 is set on one side of the swing baffle 10, and the other end is set on the locking member 9.

[0049] In this embodiment, a swing baffle 10 and a traction rope 11 are designed, wherein the swing baffle 10 is installed on the frame 1 and can swing as needed. Its main function is to catch or block materials such as soil, gravel, etc. that may be thrown out when the vehicle stops during the vehicle blocking operation, so as to prevent these materials from splashing and causing pollution to the surrounding environment or harming pedestrians, thereby improving the safety and environmental friendliness of the equipment. After the traction rope 11 is introduced into the upper surface of the swing baffle 10 and the ground before it swings, the locking of the locking member 9 needs to be realized after the traction rope 11 is tightened, that is, one end of the traction rope 11 is fixed to one side of the swing baffle 10, and the other end is connected to the locking member 9. This design cleverly links the action of the swing baffle 10 with the control of the locking member 9, and can pull or loosen the traction rope 11 through the rotation of the locking member 9 to realize the opening or closing of the swing baffle 10. At the same time, it can also be used as an auxiliary means to prompt or control the state of the locking member 9, thereby increasing the flexibility and convenience of operation. In summary, the mechanical car stopper, through the innovative design of the swing baffle 10 and the traction rope 11, not only effectively solves the incidental problems that may arise in the car stopper process, but also improves the convenience of operation of the equipment.

[0050] Furthermore, the locking member 9 has an inner tooth portion 901 , the rotating shaft 2 has an outer tooth portion 201 , and the locking member 9 is slidably disposed on the frame 1 . After the locking member 9 slides, the inner tooth portion 901 is meshed with or disengaged from the outer tooth portion 201 .

[0051] In this embodiment, the locking member 9 is provided with an inner tooth portion 901, which matches the outer tooth portion 201 on the rotating shaft 2. This design utilizes the mechanical engagement principle of gears, so that after the locking member 9 slides into place, its inner tooth portion 901 and the outer tooth portion 201 of the rotating shaft 2 can be tightly combined to form a stable mechanical matching state. The locking member 9 slides along the frame 1. When the rotating shaft 2 needs to be locked, the inner tooth portion 901 and the outer tooth portion 201 are precisely meshed through the sliding operation, thereby preventing the rotating shaft 2 from rotating and achieving the locking purpose of the car arrester. On the contrary, when unlocking is required, it is only necessary to slide the locking member 9 in the opposite direction to disengage the two tooth portions and restore the free rotation of the rotating shaft 2. High precision and self-locking: The design of tooth meshing not only improves the locking accuracy, but also ensures that the rotating shaft 2 can remain stable and not rotate even when subjected to a certain external force impact, thereby enhancing the stability and safety of the car arrester. At the same time, the self-locking characteristics of the teeth make the locking state more stable, without the need for additional locking devices, simplifying the structure and improving the overall reliability. In summary, the precise meshing design of the inner tooth portion 901 and the outer tooth portion 201 significantly enhances the reliability of the locking function and the precise control of the operation, providing a strong guarantee for the safe use of the vehicle arrester.

[0052] Furthermore, it also includes a linear drive member 12, which is arranged on the frame 1 and is used to drive the locking member 9 to slide. An infrared sensor is arranged on the frame 1 and is used to detect the passage of a human body.

[0053] In this embodiment, the introduction of the linear drive 12 makes the sliding operation of the locking member 9 more automated. The linear drive 12 is mounted on the frame 1 and can accurately control the sliding action of the locking member 9, thereby automatically completing the locking and unlocking process of the rotating shaft 2. This design not only reduces the burden of manual operation, but also improves the accuracy and efficiency of the operation. The setting of the infrared sensor is mainly used to monitor whether there are people approaching or passing through the area near the car blocker. The sensitive detection ability of the sensor can be used as a safety protection measure. When a human body is detected passing by, it can be linked with the control system to temporarily prohibit the movement of the locking member 9 to prevent injuries caused by misoperation and ensure the safety of personnel. At the same time, the infrared sensor can be set to a number, and the safety area is divided into a number of level groups. When there is no person in the action area of ​​the car blocker, the damper is used in conjunction with the brake 8. The damper is first used for preliminary deceleration. When the speed drops to a point where the material cannot be thrown out of the vehicle, the brake 8 brakes. When there are people in the braking area of ​​the car blocker, but the person is far away from the hook 3, the damper is used in conjunction with the locking member 9. The damper first slows down the vehicle. When the vehicle moves a certain distance, the swing baffle 10 is swung up, and the brake baffle is braked to prevent the material from being thrown out and causing harm to the person. When the person is in the braking area of ​​the car blocker, the brake 8 locks the brake disc 7, thereby reducing the harm to the person. In summary, the mechanical car blocker, which realizes automatic control of the locking member 9 through the linear drive member 12 and combines the intelligent monitoring of the infrared sensor, not only improves the automation level of the equipment, but also enhances the safety during use, and improves the humanization and intelligence of the mechanical car blocker.

[0054] Furthermore, there are multiple racks 1 arranged in an array.

[0055] In this embodiment, the design is no longer limited to a single rack 1, but adopts a method of arranging and setting a number of racks 1. The flexibility and scalability of this design are significantly enhanced, and it can adapt to lanes of different widths or those that require multi-point vehicle blocking control. The arranged racks 1 can be flexibly deployed according to actual needs. They can be arranged in a straight line to cover long distances, or the spacing can be adjusted as needed or formed into a specific array to cope with different vehicle models or specific vehicle blocking needs, thereby improving the versatility and adaptability of the vehicle blocker. The arrangement of multiple racks 1 provides new possibilities for the control of the vehicle blocker. It can be designed so that each rack 1 is independently controlled to meet the individual operation requirements of different areas; it can also realize synchronous linkage control to ensure that all racks 1 act at the same time to achieve a unified and efficient vehicle blocking effect. In summary, the mechanical vehicle blocker not only broadens the scope of application through the multi-rack 1 arrangement design, but also enhances the flexibility of system layout and the diversity of control.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
