Anti-collision device with buffer mechanism for transportation engineering

Abstract

This utility model discloses an anti-collision device with a buffer mechanism for transportation engineering, including a protective plate. An mounting plate is installed on the outer wall of the protective plate, and a vertical plate is fixedly connected to the outer wall of the mounting plate. A threaded rod is rotatably connected to the inner wall of the vertical plate via a bearing. This utility model relates to the field of transportation technology. Through the cooperation of the threaded rod, slider, and damping device, when the protective plate is impacted, the connecting rod drives the slider to move on the outer wall of the threaded rod, compressing the spring. Furthermore, the threaded rod rotates through the threads on the outer wall, and under the restriction of the damping device, the threaded rod rotates slowly, thus slowing down the movement speed of the slider on the outer wall of the threaded rod and reducing the deformation speed of the spring. This avoids repeated spring rebound and solves the problem that large elastic deformation of the spring leads to secondary impacts with the impactor, causing repeated rebounds and reducing the protective effect.

Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to an anti-collision device with a buffer mechanism for transportation engineering. Background Technology

[0002] Transportation facilities refer to the necessary tools (including vehicles, ships, and aircraft), machinery and equipment, sites, routes, and communication equipment used in transportation. Transportation facilities play an important role in ensuring traffic safety and mitigating the severity of potential accidents.

[0003] In existing technology, when traffic facilities are impacted, the first buffer is provided. A second buffer is provided by setting up anti-collision plates, push rods, slide cylinders, first compression springs, and slide rods. By setting up the above structures, the protective equipment can buffer and absorb shock when it is impacted.

[0004] However, in actual use, since the protective device uses springs to absorb the impact of the crash plate, and the elastic deformation of the springs is relatively large, the springs and crash plates will cause secondary impacts on the impacting object, resulting in repeated rebounds, which reduces the protective effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a collision avoidance device with a buffer mechanism for transportation engineering. This solves the problem that in actual use, the protective device relies on springs to absorb the impact of the collision plate. However, the large elastic deformation of springs causes the spring and the collision plate to repeatedly impact the object, resulting in repeated rebounds and a reduction in the protective effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance device with a buffer mechanism for transportation engineering, comprising a protective plate, an mounting plate installed on the outer wall of the protective plate, a vertical plate fixedly connected to the outer wall of the mounting plate, a threaded rod rotatably connected to the inner wall of the vertical plate via a bearing, a slider threadedly connected to the outer wall of the threaded rod, a connecting block fixedly connected to the outer wall of the slider, a connecting rod rotatably connected to the outer wall of the connecting block via a pin, the end of the connecting rod rotatably connected to the outer wall of the protective plate via a pin, a spring sleeved on the outer wall of the threaded rod, the spring pressing against the slider and the vertical plate, and a damping device installed at one end of the threaded rod that passes through the vertical plate.

[0007] Preferably, the damping device includes a friction wheel, which is fixedly connected to one end of the threaded rod that passes through the vertical plate. A locking block is pressed against the outer wall of the friction wheel. A fixing rod is fixedly connected to the top of the locking block. A fixing block is sleeved on the outer wall of the fixing rod. The outer wall of the fixing block is fixedly connected to the outer wall of the vertical plate.

[0008] Preferably, the outer wall of the fixing rod is abutted against a bolt rod, the outer wall of the bolt rod is threadedly connected to a limit plate, and the outer wall of the limit plate is fixedly connected to the outer wall of the fixing block.

[0009] Preferably, the outer wall of the protective plate is fixedly connected to a plug rod, the outer wall of the plug rod is sleeved with a fixing cylinder, and the outer wall of the fixing cylinder is fixedly connected to the outer wall of the mounting plate.

[0010] Preferably, the outer wall of the mounting plate is fixedly connected to the fixing plate by bolts, and a shock-absorbing pad is abutting between the fixing plate and the mounting plate.

[0011] Beneficial effects

[0012] This utility model provides a collision avoidance device with a buffer mechanism for transportation engineering. It has the following beneficial effects: Through the cooperation of a threaded rod, a slider, and a damping device, when the protective plate is impacted, the connecting rod drives the slider to move along the outer wall of the threaded rod, compressing the spring. Furthermore, the threaded rod rotates through the threads on its outer wall, and under the restriction of the damping device, the threaded rod rotates slowly, thus slowing down the movement speed of the slider along the outer wall of the threaded rod and reducing the deformation speed of the spring. This avoids repeated spring rebound and solves the problem that large elastic deformation of the spring leads to secondary impacts with the impactor, causing repeated rebounds and reducing the protective effect.

[0013] Through the cooperation of the protective plate, the insert rod, and the protective plate, when the protective plate is moved by an impact, it will drive the internal movement of the insert rod fixing cylinder, so that the protective plate is stable when it moves, avoiding the problem that uneven force will cause angular deformation between the protective plate and the mounting plate, which would reduce the buffering effect of the protective device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In actual use, the protective device uses a spring to absorb the impact of the impact on the anti-collision plate. However, the spring has a large elastic deformation, which causes the spring and the anti-collision plate to make secondary impacts on the impacting object, resulting in repeated rebounds and thus reducing the protective effect.

[0021] In view of this, the present invention provides a collision avoidance device with a buffer mechanism for transportation engineering, which solves the problem that in actual use, the protective device uses a spring to absorb the impact of the collision plate, but the spring has a large elastic deformation, which causes the spring and the collision plate to hit the impacting object a second time, resulting in repeated rebound and thus reducing the protective effect.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a collision avoidance device with a buffer mechanism for transportation engineering includes a protective plate 1, an mounting plate 3 installed on the outer wall of the protective plate 1, a vertical plate 8 fixedly connected to the outer wall of the mounting plate 3, a threaded rod 9 rotatably connected to the inner wall of the vertical plate 8 via a bearing, a slider 11 threadedly connected to the outer wall of the threaded rod 9, a connecting block 12 fixedly connected to the outer wall of the slider 11, a connecting rod 7 rotatably connected to the outer wall of the connecting block 12 via a pin, the end of the connecting rod 7 rotatably connected to the outer wall of the protective plate 1 via a pin, a spring 13 sleeved on the outer wall of the threaded rod 9, the spring 13 pressing against the slider 11 and the vertical plate 8, and a damping device installed at one end of the threaded rod 9 that passes through the vertical plate 8;

[0024] In the specific implementation process, it is worth noting that the protective plate 1, as the directly load-bearing component, bears the responsibility of intercepting the initial impact force during the collision. The outer wall of the protective plate 1 is fitted with an mounting plate 3 via a stable connection structure. The vertical plate 8, as the core support component of the buffer mechanism, provides a stable installation reference for subsequent buffer components. The inner wall of the vertical plate 8 is rotatably connected to a threaded rod 9 via a high-precision bearing. The bearing connection ensures that the threaded rod 9 maintains a low-friction state when rotating under force, avoiding mechanical jamming that could affect the buffering effect. The outer wall of the threaded rod 9 is threadedly connected to a slider 11, achieving initial force dispersion. The connecting block 12 is rotatably connected to the connecting rod 7 via a pin. The end of the connecting rod 7 is also rotatably connected to the outer wall of the protective plate 1 via a pin. This double-pin rotatable connection structure allows for a flexible connection between the protective plate 1 and the slider 11. The force transmission path of the activity is as follows: when the protective plate 1 is subjected to a collision force, it can push the slider 11 to move along the threaded rod 9 through the connecting rod 7. When the slider 11 moves under the push of the connecting rod 7, it will compress the spring 13. The spring 13 absorbs the collision energy through its own elastic deformation, achieving a first-level buffer. At the same time, the threaded engagement between the threaded rod 9 and the slider 11 forms a certain damping effect, slowing down the movement speed of the slider 11 and further enhancing the buffering performance. This reduces the rotation speed of the threaded rod 9, thereby slowing down the movement speed of the slider 11 and reducing the rebound speed of the spring 13, avoiding repeated rebound that could cause the protective plate 1 to collide with the impacting object and cause secondary damage. The thread angle on the outer wall of the threaded rod 9 is relatively large, which needs to ensure that the slider 11 can drive the threaded rod 9 to rotate when it moves laterally on the outer wall of the threaded rod 9.

[0025] Furthermore, the damping device includes a friction wheel 10, which is fixedly connected to one end of the threaded rod 9 that passes through the vertical plate 8. A locking block 14 is pressed against the outer wall of the friction wheel 10. A fixing rod 16 is fixedly connected to the top of the locking block 14. A fixing block 15 is sleeved on the outer wall of the fixing rod 16. The outer wall of the fixing block 15 is fixedly connected to the outer wall of the vertical plate 8.

[0026] In the specific implementation process, it is worth noting that the friction wheel 10 is fixedly connected to one end of the threaded rod 9 that passes through the vertical plate 8. When the threaded rod 9 rotates due to collision force, it can synchronously drive the friction wheel 10 to rotate, realizing the transmission and conversion of force. The outer wall of the friction wheel 10 is tightly pressed against the locking block 14. The contact surface between the two is roughened to increase the friction coefficient, ensuring that stable frictional resistance can be generated during relative motion. The top of the locking block 14 is fixedly connected to the fixing rod 16. The outer wall of the fixing rod 16 is sleeved with a fixing block 15, forming a sliding guide support structure. The outer wall of the fixing block 15 is fixedly connected to the outer wall of the vertical plate 8, so that the entire damping assembly forms a rigid connection with the main frame of the device, ensuring the structural stability during operation. When the friction wheel 10 rotates, the friction force generated between its surface and the locking block 14 will push the locking block 14. Block 14 reciprocates along the axis of fixed rod 16, while fixed block 15 provides a stable sliding guide for fixed rod 16, preventing block 14 from shifting or jamming. When a collision occurs, threaded rod 9 drives friction wheel 10 to rotate. The frictional resistance between friction wheel 10 and block 14 will hinder the rotation speed of threaded rod 9, converting the kinetic energy generated by the collision into frictional heat energy and dissipating it, thus achieving energy dissipation of secondary buffering. At the same time, block 14 can automatically adjust the contact pressure according to the magnitude of friction force by sliding fixed rod 16 within fixed block 15, ensuring that the damping force is always kept within a reasonable range. This structural design does not require complex hydraulic or pneumatic components and can achieve a stable damping effect through pure mechanical friction. It has advantages such as simple structure, high reliability, and convenient maintenance, and can effectively cooperate with the elastic buffering effect of spring 13 to further reduce the impact force transmitted to the foundation structure.

[0027] Furthermore, the outer wall of the fixing rod 16 is pressed against the bolt rod 18, and the outer wall of the bolt rod 18 is threadedly connected to the limiting plate 17. The outer wall of the limiting plate 17 is fixedly connected to the outer wall of the fixing block 15.

[0028] In the specific implementation process, it is worth noting that by rotating the bolt rod 18, the pressure of the bolt rod 18 against the fixing rod 16 is changed. When adjusting the position of the fixing rod 16, the bolt rod 18 is loosened, and the fixing rod 16 is pressed against the outer wall of the friction wheel 10. After adjustment, the bolt rod 18 is rotated to fix the fixing rod 16, so that the fixing rod 16 is stable when fixed.

[0029] Example 2: From Figure 1-4 It can be seen that the outer wall of the protective plate 1 is fixedly connected to the insert rod 6, the outer wall of the insert rod 6 is sleeved with the fixing cylinder 5, and the outer wall of the fixing cylinder 5 is fixedly connected to the outer wall of the mounting plate 3.

[0030] In the specific implementation process, it is worth noting that the outer wall of the protective plate 1 is fixedly connected to a rod 6. The rod 6 is made of high-strength metal and can withstand the lateral and axial forces generated during a collision. A fixing cylinder 5 is sleeved on the outer wall of the rod 6, and the two are designed with a clearance fit. This ensures that the rod 6 can slide smoothly inside the fixing cylinder 5, while limiting the offset of the rod 6 through the cylinder wall, thus playing a precise guiding role. The outer wall of the fixing cylinder 5 is fixedly connected to the outer wall of the mounting plate 3, so that this component forms a rigid connection with the basic frame of the device, providing a stable support benchmark for the protective plate 1. When the protective plate 1 is subjected to a collision force, in addition to pushing the slider 11 to move through the connecting rod 7, it will also... The movable insert rod 6 extends and retracts along the axial direction of the fixed cylinder 5. The inner wall of the fixed cylinder 5 is smoothed to reduce the frictional resistance when the insert rod 6 slides, ensuring that the protective plate 1 can deform and buffer evenly with the impact force. At the same time, the cooperation between the insert rod 6 and the fixed cylinder 5 can effectively limit the lateral swing of the protective plate 1, avoiding deformation or damage to the device structure due to uneven force. In addition, this structure, together with the spring 13, damping device, etc., constitutes a multi-buffering system. The insert rod 6 and the fixed cylinder 5 mainly play the role of guidance and auxiliary support, ensuring that the protective plate 1 maintains a stable movement trajectory during the collision, so that the buffer component can be evenly stressed and fully exert its energy absorption function, thereby further improving the protective performance and service life of the entire anti-collision device.

[0031] Furthermore, the outer wall of the mounting plate 3 is fixedly connected to the fixing plate 2 by bolts, and a shock-absorbing pad 4 is pressed between the fixing plate 2 and the mounting plate 3;

[0032] In the specific implementation process, it is worth noting that the outer wall of the mounting plate 3 is fixedly connected to the fixing plate 2 by bolts. The bolt connection method has the characteristics of firm connection and convenient disassembly and assembly, which facilitates the installation, maintenance and replacement of the device. A shock-absorbing pad 4 is pressed between the fixing plate 2 and the mounting plate 3. The shock-absorbing pad 4 is usually made of materials with high elasticity and fatigue resistance, such as rubber and polyurethane. Its thickness is designed according to the actual shock absorption requirements. When the anti-collision device is subjected to a collision force, the impact force will be transmitted to the mounting plate 3 in sequence through the protective plate 1, connecting rod 7, slider 11, threaded rod 9 and other components. At this time, the shock-absorbing pad 4 will be pressed between the mounting plate 3 and the fixing plate 2. The damping pad 4 undergoes elastic deformation and absorbs part of the impact energy through its own compression and rebound, thus playing a primary role in shock absorption. At the same time, the damping pad 4 can also effectively reduce the transmission of vibrations generated by the collision, preventing rigid impacts from damaging the external installation foundation. In addition, the rubber damping pad 4 also has a certain sealing and buffering effect, which can reduce rigid friction and noise between the mounting plate 3 and the fixing plate 2, and extend the service life of the device. This structure, together with the spring 13, the damping device, and the guide support structure of the plug rod 6 and the fixing cylinder 5, forms a multi-layered and all-round buffer and shock absorption system, which significantly improves the overall protective performance and safety of the anti-collision device.
