Technical Field

[0001] This utility model relates to the field of garbage truck compartment technology, and in particular to a locking mechanism for detachable garbage truck compartments. Background Technology

[0002] Garbage trucks are specialized vehicles used for collecting, transporting, and processing household waste using techniques such as compression and crushing. They can also be called garbage collection trucks or transfer trucks. In order to help the detachable garbage truck compartments be stably locked during transport, a locking mechanism for the detachable garbage truck compartments is needed.

[0003] However, in the practical application of detachable garbage trucks, the opening method of the compartment door directly affects the garbage loading and unloading efficiency and operational safety. Currently, most detachable garbage trucks use electro-hydraulic or pneumatic systems to drive the compartment door opening. Although this type of automation can achieve rapid operation, it has obvious defects. Once the core electrical components such as the motor and hydraulic pump malfunction, or encounter situations such as power supply interruption, aging wiring, or short circuit, the compartment door will not be able to open normally, resulting in garbage not being unloaded in time and seriously delaying the operation progress. Therefore, a locking mechanism for the compartment of detachable garbage trucks is proposed to solve the above problems. Utility Model Content

[0021] 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.

[0022] Reference Figure 1-4 A locking mechanism for a detachable garbage truck compartment includes a vehicle body 1, a compartment body 2 mounted on top of the vehicle body 1, a top plate 4 fixedly mounted on the top side of the compartment body 2, a toothed plate 7 mounted below the top plate 4, a compartment door 8 fixedly mounted on one side of the toothed plate 7, a limit component between the toothed plate 7 and the top plate 4, a circular hole on one side of the compartment body 2, a rotating column 13 disposed within the circular hole, a fixing plate 12 fixedly mounted on the bottom side of the top plate 4, one end of the rotating column 13 being rotatably connected to one side of the fixing plate 12, and a gear 14 fixedly sleeved on the outer side of the rotating column 13, the gear 14 meshing with the toothed plate 7, and the rotating column 1... The other end of 3 is fixedly fitted with a handwheel 17. The carriage body 2 is equipped with an electric drive component and a guide component. With the handwheel 17, when the motor 9 is damaged, the door 8 needs to be opened manually. At this time, open the door on one side of the carriage body 3, then hold the handwheel 17 and turn it clockwise. Since the handwheel 17 is fixedly connected to the rotating column 13, when the handwheel 17 is turned clockwise, the rotating column 13 will drive the gear 14 to rotate clockwise, thereby realizing the manual opening of the carriage door 8. There are two handwheels 17 and two motors 9, so two carriage doors 8 can be opened at the same time as needed.

[0023] Specifically, the limiting component includes a groove 5 on the bottom side of the top plate 4, a slider 6 slidably installed in the groove 5, and the bottom side of the slider 6 is fixedly connected to the top side of the toothed plate 7. By providing the slider 6, the slider 6 can provide stable guidance and limiting function when the toothed plate 7 moves, thereby ensuring that the toothed plate 7 is always meshed with the gear 14.

[0024] Specifically, the electric drive assembly includes a motor 9 fixedly mounted on one side of the carriage body 2. The output end of the motor 9 rotates through the carriage body 2 and is fixedly connected to a rotating rod 10. A first synchronous pulley 11 is fixedly sleeved on the outer side of the rotating rod 10, and a second synchronous pulley 15 is fixedly sleeved on the outer side of the rotating column 13. The second synchronous pulley 15 and the first synchronous pulley 11 share the same synchronous belt 16. By providing the motor 9, when the carriage door 8 needs to be opened electrically, the motor 9 is started to drive the rotating rod 10 to rotate clockwise. The first synchronous pulley 11 is fixedly sleeved on the outer side of the moving rod 10. The first synchronous pulley 11 and the second synchronous pulley 15 share the same synchronous belt 16. Therefore, under the meshing transmission of the synchronous belt 16, the second synchronous pulley 15 will synchronously drive the rotating column 13 connected to it to rotate clockwise. Since the gear 14 is fixedly sleeved on the outer side of the rotating column 13, and the gear 14 meshes with the toothed plate 7, under the meshing transmission of the gear 14, the toothed plate 7 will drive the door 8 fixedly connected on one side to open outward, thereby realizing electric door opening.

[0025] Specifically, the guide assembly includes two connecting plates 18 fixedly installed on the bottom side of the top plate 4. The two connecting plates 18 are fixedly connected to the same fixing rod 19. A guide plate 20 is slidably sleeved on the outside of the fixing rod 19. The guide plate 20 is L-shaped. The other side of the guide plate 20 is fixedly connected to one side of the door 8. By setting the guide plate 20, the guide plate 20 can play a guiding and limiting role when the door 8 moves, so as to prevent one side of the door 8 from tilting downward.

[0026] Specifically, a box 3 is fixedly installed on one side of the carriage body 2, and a box door is provided on one side of the box 3. The handwheel 17 is located inside the box 3. By setting up the box 3, the box 3 provides dual protection for manual door opening operation and safety protection. When it is necessary to manually open the carriage door, the box door of the box 3 is opened, and the handwheel 17 can be directly grasped for operation. When no manual intervention is required, the box door remains closed to prevent personnel from accidentally touching the high-speed rotating handwheel 17 during the process of the motor 9 driving the carriage door to open, thereby avoiding safety risks and improving the safety of the locking mechanism operation and the service life of the components.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0028] In use: When the compartment door 8 needs to be opened electrically, the motor 9 is started. The operation of the motor 9 drives the rotating rod 10 to rotate clockwise. Since the first synchronous pulley 11 is fixedly sleeved on the outside of the rotating rod 10, and the first synchronous pulley 11 and the second synchronous pulley 15 are connected by the same synchronous belt 16, under the meshing transmission action of the synchronous belt 16, the second synchronous pulley 15 will drive the rotating column 13 connected to it to rotate clockwise synchronously. Since the gear 14 is fixedly sleeved on the outside of the rotating column 13, and the gear 14 meshes with the gear plate 7, as the gear 14 rotates, the gear plate 7 will drive the compartment door 8 fixedly connected to one side to open outward, thereby completing the electric opening. The door is operated manually. However, when the motor 9 malfunctions and cannot work properly, the compartment door 8 must be opened manually. In this case, open the compartment door on one side of the box body 3, grasp the handwheel 17 and turn it clockwise. Since the handwheel 17 is fixedly connected to the rotating column 13, when the handwheel 17 is turned, the rotating column 13 will drive the gear 14 to rotate clockwise synchronously, thereby driving the gear plate 7 to open the compartment door 8, realizing the manual door opening function. In addition, there are two handwheels 17 and two motors 9. According to actual needs, one compartment door 8 can be opened individually, or both components can be operated at the same time to realize the synchronous opening of the two compartment doors 8, which greatly improves the flexibility and convenience of use.
