Description

Technical Field

[0001] This utility model belongs to the technical field of shuttle vehicle protection equipment, specifically relating to a shuttle vehicle emergency stop and buffer protection device. Background Technology

[0002] An aerial shuttle is a suspended or rail-mounted logistics device, typically installed on elevated tracks, used to transport materials or goods in the air. Through precise positioning, automatic grabbing, and conveying functions, it achieves efficient and flexible material handling. An aerial shuttle system usually includes modules such as tracks, execution units, and scheduling and control systems, and can adapt to a variety of complex production environments. With its high efficiency, intelligence, and space-saving features, the aerial shuttle has become an important piece of equipment in modern intelligent logistics and production systems.

[0003] In existing shuttle buses, when obstacles appear in front of the shuttle bus while it is in motion, it is not easy for the shuttle bus to stop in an emergency. The shuttle bus is prone to collision with the obstacles, resulting in damage to the shuttle bus. At the same time, the shuttle bus lacks a buffer protection mechanism, which makes the shuttle bus easily severely damaged in the event of a collision, affecting its use. Utility Model Content

[0004] The purpose of this invention is to provide an emergency stop and buffer protection device for shuttle cars to solve the damage problem during shuttle car collisions and protect the safety of equipment and goods.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An emergency stop and buffer protection device for a shuttle vehicle includes: a vehicle body and a track. A base plate is fixedly installed on the outer walls of both ends of the vehicle body. A mounting box is fixedly installed on the top of the base plate. A partition plate is fixedly installed on the inner wall of the mounting box. A connecting cavity and a mounting cavity are formed at the top and bottom of the partition plate, respectively. A connecting assembly is provided in the connecting cavity. A protective plate is connected to the connecting assembly. A buffer mechanism is provided between the protective plate and the vehicle body. A braking assembly is provided on the top of the mounting box. A sensor is fixedly installed on the top of the mounting box.

[0007] The buffer mechanism includes an airbag fixedly disposed between the vehicle body and the protective plate. A connecting pipe is fixedly disposed between the airbag and the mounting cavity. A piston plate is slidably disposed on the inner side wall of the mounting cavity. A damper is fixedly disposed on the inner side wall of the mounting cavity. The end of the piston rod of the damper is fixedly connected to the outer side wall of the piston plate. A reset assembly is provided in the mounting cavity.

[0008] Preferably, the reset assembly includes a fixing plate fixedly disposed on the inner side wall of the mounting cavity. The fixing plate has an opening adapted to the damper. Two symmetrically arranged sleeve rods are fixedly disposed on the outer side wall of the fixing plate. A movable rod is slidably disposed on the inner side wall of the sleeve rod. The end of the movable rod is fixedly connected to the outer side wall of the piston plate. A spring is fixedly disposed between the movable rod and the inner side wall of the sleeve rod.

[0009] Preferably, the connecting assembly includes a fixing plate two fixedly disposed on the inner sidewall of the connecting cavity, and a plurality of guide rods one fixedly disposed between the fixing plate two and the inner sidewall of the connecting cavity.

[0010] Preferably, a movable plate is slidably sleeved on one of the plurality of guide rods, and a connecting rod is fixedly provided on the outer wall of the movable plate. The end of the connecting rod away from the movable plate passes through the mounting box and is fixedly connected to the outer wall of the protective plate.

[0011] Preferably, the braking assembly includes two symmetrically arranged top plates, a first braking plate is fixedly disposed at the bottom of the top plates, a second braking plate is disposed directly below the bottom of the first braking plate, the outer walls of the two second braking plates are fixedly connected to the outer wall of the track, and the outer walls of the first braking plate and the second braking plate at opposite ends are both roughened.

[0012] Preferably, the connecting cavity is provided with a movable plate, and a connecting plate is fixedly provided on the top of the movable plate. The top of the connecting plate passes through the mounting box and is fixedly connected to the outer wall of the top plate.

[0013] Preferably, an electric push rod is fixedly installed on the top of the partition plate, the top of the electric push rod is fixedly connected to the bottom of the movable plate, and a plurality of guide rods are slidably installed through the movable plate, the top and bottom of the guide rods being fixedly connected to the top of the mounting box and the top of the partition plate, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting up and using the buffer mechanism, when the shuttle car collides with an obstacle, the protective plate first contacts the obstacle, the airbag is quickly squeezed to absorb the impact force, and at the same time the airbag delivers gas to the connecting cavity through the connecting pipe, pushing the piston plate to move, so that the damper further consumes the impact energy through the movement of the piston rod, effectively reducing the damage to the shuttle car from the collision and protecting the safety of equipment and goods.

[0016] (2) The braking assembly monitors the operation status of the shuttle in real time through sensors. When an obstacle is detected in front, the sensor sends a signal, and the electric push rod quickly pushes the movable plate, causing the top plate and the first brake plate to contact the second brake plate on the track. Emergency braking is achieved through the friction of the rough surface, ensuring that the shuttle stops in the shortest time and avoids collision. Attached Figure Description

[0024] Example 1:

[0025] Please see Figures 1-4 As shown, a shuttle emergency stop and buffer protection device includes: a car body 1 and a track 2. A base plate 3 is fixedly installed on the outer side walls at both ends of the car body 1. An installation box 4 is fixedly installed on the top of the base plate 3. A partition plate 5 is fixedly installed on the inner side wall of the installation box 4. A connecting cavity and an installation cavity are formed at the top and bottom of the partition plate 5, respectively. A connecting component is provided in the connecting cavity. A protective plate 6 is connected to the connecting component. A buffer mechanism is provided between the protective plate 6 and the car body 1. A braking component is provided on the top of the installation box 4. A sensor 22 is fixedly installed on the top of the installation box 4.

[0026] The buffer mechanism includes an airbag 7 fixedly installed between the vehicle body 1 and the protective plate 6. A connecting pipe 8 is fixedly installed between the airbag 7 and the mounting cavity. A piston plate 9 is slidably installed on the inner side wall of the mounting cavity. A damper 10 is fixedly installed on the inner side wall of the mounting cavity. The piston rod end of the damper 10 is fixedly connected to the outer side wall of the piston plate 9. A reset assembly is provided in the mounting cavity.

[0027] As can be seen from the above, when the car body 1 is running normally on the track 2, the protective plate 6 is in the initial position, the airbag 7 is in the inflated state, and the piston rod of the damper 10 is in the initial position. When the car body 1 collides with an obstacle, the protective plate 6 contacts the obstacle first, the airbag 7 is quickly squeezed, absorbing part of the impact force. At the same time, the airbag 7 delivers gas to the installation cavity through the connecting pipe 8, pushing the piston plate 9 to move towards the damper 10. The damper 10 further consumes the impact energy through the movement of the piston rod, effectively reducing the damage to the car body 1 from the collision, providing buffer protection for the car body 1, and protecting the safety of the equipment and cargo.

[0028] This design of the buffer mechanism can not only effectively absorb and dissipate impact energy, but also prevent the vehicle body 1 from shaking violently after a collision through the stabilizing effect of the damper 10, ensuring the stability of the equipment and the safety of the cargo. In addition, by setting and using the reset component, the airbag 7, piston plate 9 and damper 10 can be automatically restored to their initial state after a collision, ensuring the reusability of the device and reducing maintenance costs.

[0029] Specifically, regarding the aforementioned reset component, please refer to... Figure 3 As shown, the reset assembly includes a fixed plate 11 fixedly mounted on the inner side wall of the mounting cavity. The fixed plate 11 has an opening adapted to the damper 10. Two symmetrically arranged sleeve rods 12 are fixedly mounted on the outer side wall of the fixed plate 11. A movable rod 13 is slidably mounted on the inner side wall of the sleeve rod 12. The end of the movable rod 13 is fixedly connected to the outer side wall of the piston plate 9. A spring 14 is fixedly mounted between the movable rod 13 and the inner side wall of the sleeve rod 12.

[0030] As shown above, when the airbag 7 is compressed, the piston plate 9 moves and the spring 14 is compressed. After the collision ends, the elastic force of the spring 14 pushes the piston plate 9 back to its initial position. At the same time, the piston plate 9 drives the piston rod of the damper 10 to return to its initial state. The piston plate 9 delivers air from the mounting cavity to the airbag 7, causing the airbag 7 to return to its inflated state, ensuring that the buffer mechanism can be used normally again. This reset design is simple and reliable, effectively improving the service life and reliability of the device.

[0031] Specifically, regarding the aforementioned connection components, please refer to... Figure 1 , Figure 3 and Figure 4 As shown, the connecting assembly includes a fixing plate 15 fixedly disposed on the inner side wall of the connecting cavity, and a plurality of guide rods 16 fixedly disposed between the fixing plate 15 and the inner side wall of the connecting cavity;

[0032] Multiple guide rods 16 are slidably sleeved with movable plates 17. A connecting rod 18 is fixedly installed on the outer wall of the movable plate 17. The end of the connecting rod 18 away from the movable plate 17 passes through the mounting box 4 and is fixedly connected to the outer wall of the protective plate 6.

[0033] As can be seen from the above, this connection method ensures that the protective plate 6 can stably transmit force when it is impacted. Through the cooperation of the guide rod 16 and the moving plate 17, the movement of the protective plate 6 is made more stable, preventing deviation or shaking during the collision, and further improving the stability and reliability of the device.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 and Figure 3 As shown, the braking assembly includes two symmetrically arranged top plates 19. A first brake plate 20 is fixedly arranged at the bottom of the top plate 19. A second brake plate 21 is arranged directly below the bottom of the first brake plate 20. The outer walls of the two second brake plates 21 are fixedly connected to the outer wall of the track 2. The outer walls of the first brake plate 20 and the second brake plate 21 at opposite ends are both roughened.

[0036] A movable plate 23 is provided inside the connecting cavity, and a connecting plate 24 is fixedly installed on the top of the movable plate 23. The top of the connecting plate 24 passes through the mounting box 4 and is fixedly connected to the outer wall of the top plate 19.

[0037] As can be seen from the above, the braking assembly monitors the running status of the vehicle body 1 in real time through sensor 22. Sensor 22 is an infrared sensor or millimeter-wave radar to monitor obstacles in front. When sensor 22 detects an obstacle in front, it immediately sends a signal to the control system. The control system activates electric push rod 25, which pushes movable plate 23 to move downward. Movable plate 23 drives top plate 19 to move downward through connecting plate 24. The first brake plate 20 at the bottom of top plate 19 contacts the second brake plate 21 on track 2. Through the friction between the rough surfaces of the two, emergency braking is achieved to ensure that the vehicle body 1 stops in the shortest possible time and avoids collision with obstacles.

[0038] This design of the braking assembly provides a rapid response, enabling it to complete the braking action in a very short time after detecting an obstacle, effectively improving the safety of the vehicle body 1. The friction braking method using a rough surface not only provides good braking performance but also reduces wear on the track 2, the first brake plate 20, and the second brake plate 21, thus extending the service life of the equipment.

[0039] Preferably, an electric push rod 25 is fixedly installed on the top of the partition plate 5. The top of the movable rod of the electric push rod 25 is fixedly connected to the bottom of the movable plate 23. Multiple guide rods 26 are slidably installed through the movable plate 23. The top and bottom of the guide rods 26 are fixedly connected to the top of the mounting box 4 and the top of the partition plate 5, respectively.

[0040] As can be seen from the above, the stability of the electric push rod 25 and the guiding function of the guide rod 26 ensure that the movable plate 23 remains stable during movement, preventing the movable plate 23 from shifting due to external forces and affecting the braking effect. This design improves the reliability and stability of the braking assembly, ensuring that the braking task can be completed quickly and accurately in emergency situations.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
