Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, and in particular to a detachable garbage truck body support device. Background Technology

[0002] Currently, detachable garbage trucks are widely used in urban and rural garbage collection and transportation. Their core working principle is to connect the garbage container to the vehicle frame through a towing hook. During the towing process, the bottom of the garbage container contacts the rollers at the rear of the vehicle frame. With the help of the rolling characteristics of the rollers and the synergistic effect of the towing frame, the garbage container is smoothly loaded onto the vehicle frame. This design greatly improves the efficiency of garbage transfer and reduces the intensity of manual operation, making it an important piece of equipment for modern sanitation operations. However, most existing detachable garbage trucks rely on hydraulic telescopic booms as the driving force for tipping, tilting, and disassembling the truck body. When the hydraulic telescopic boom fails due to pipe rupture, aging seals, or hydraulic oil leakage, the truck body will fall back under its own weight, which can easily cause safety accidents. In addition, existing garbage trucks generally lack reliable auxiliary positioning structures, which cannot effectively support and limit the truck body when the hydraulic system fails. This may not only cause damage to the vehicle and garbage container, but also pose a serious threat to surrounding personnel and facilities, making them relatively impractical. Utility Model Content

[0003] In view of the problems of existing detachable garbage trucks relying on hydraulic telescopic rods to drive the truck body, which are prone to falling back due to gravity when the hydraulic system fails, and lack of effective auxiliary positioning structure, resulting in easy damage to the vehicle and the truck body, threatening the safety of personnel and facilities, and having poor practicality, this utility model is proposed.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detachable garbage truck body support device, including symmetrically arranged frames, a body provided above the two frames, a fixed frame symmetrically provided at one end of the body, a tie rod fixedly connected between the upper parts of the two fixed frames, a flipping mechanism provided between the frames, and a support mechanism connected below the flipping mechanism; The support mechanism includes a slide rail, both sides of which are fixedly connected to the frame on one side by several fixing blocks. A slide seat is slidably installed inside the slide rail, and the slide seat is hinged to the flipping mechanism through a support rod.

[0005] As a preferred embodiment, the support mechanism further includes racks symmetrically arranged within the slide rail, with the racks located on both sides of the slide block. A cavity is formed inside the slide block, and a bidirectional telescopic rod is fixedly installed within the cavity. Both telescopic ends of the bidirectional telescopic rod extend to the outside of the slide block and are connected to pawls. The pawls are rotatably sleeved on the outside of the telescopic ends of the bidirectional telescopic rod, with the lower end of the pawl engaging with the rack. A rotating sleeve and a torsion spring are fitted onto the outer walls of both telescopic ends of the bidirectional telescopic rod, with the rotating sleeve located inside the torsion spring. The rotating sleeve is rotatably connected to the telescopic ends of the bidirectional telescopic rod. Both ends of the torsion spring are fixedly connected to the outer walls of the pawl and the rotating sleeve, respectively. Symmetrically shaped storage grooves are formed on the outer wall of the slide block, corresponding to the pawls.

[0006] As a preferred embodiment, a limiting rod is fixedly connected to one side of the outer wall of the rotating sleeve, and one end of the limiting rod is in contact with the side wall of the storage slot near the carriage. The limiting rod is located on the side of the torsion spring away from the pawl. The inner wall of the slide rail is assembled in a convex shape. A groove is provided on the top of the slide block. Connecting plates are symmetrically arranged in the groove. One end of the support rod is located between the connecting plates, and the support rod is hinged to the connecting plate.

[0007] As a preferred embodiment, the tilting mechanism includes a rotating rod located between two frames. Both ends of the rotating rod are rotatably connected to the frames on both sides. A fixing plate is fixedly connected to the outer wall of the rotating rod. A support plate is fixedly connected to the end of the fixing plate away from the rotating rod. A fixing hook is connected to the side of the support plate near the fixing plate via an adjustment assembly. Fixing rods are fixedly installed at symmetrical positions on both sides of the fixing plate. Hydraulic telescopic rods are symmetrically provided on the outer side of the fixing plate. Both ends of the hydraulic telescopic rods are hinged to the fixing rods and the side wall of one side of the frame, respectively.

[0008] As a preferred embodiment, the adjustment assembly includes an adjustment plate disposed on the side of the support plate near the carriage. The upper end of the adjustment plate is fixedly connected to a fixing hook. The adjustment plate and the sidewall of the fixing hole are provided with a plurality of fixing holes at equal intervals. The adjustment plate and the support plate are connected by a plurality of fixing bolts, and the fixing bolts pass through the corresponding fixing holes on the support plate and the adjustment plate.

[0009] As a preferred embodiment, the bottom of the fixing plate is hinged to the upper end of the support rod, the fixing plate and the support plate are arranged vertically, and reinforcing plates are provided on both sides of the connection between the fixing plate and the support plate.

[0010] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its support mechanism, allows the tilting mechanism to tilt or disassemble the vehicle compartment. Simultaneously, it drives the support rod to pull the slide block within the slide rail. The slide block also moves the pawls on both sides synchronously. When the hydraulic telescopic rod stops working or malfunctions, the rack and pawls work together to lock and limit the position of the slide block, preventing it from moving back to its initial position. This restricts and fixes the support rod, creating a triangular support structure between the support rod and the fixed plate. This provides stable support and limitation for the tilting mechanism, thus supporting the vehicle compartment. This prevents the vehicle compartment from falling due to its own weight when the hydraulic telescopic rod fails due to pipe rupture, seal aging, or hydraulic oil leakage, which could damage the vehicle or garbage container, or pose a serious threat to surrounding personnel and facilities. Therefore, this invention is more practical.

[0011] 2. This utility model, through the adjustment component, allows for the corresponding adjustment of the height position of the fixing hook according to the height of the carriage, thereby improving the applicability of the equipment. Attached Figure Description

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Reference Figures 1-5 As shown, a detachable garbage truck body support device is provided, including symmetrically arranged frames 1, with a truck body 2 on top of the two frames 1. A fixed frame 3 is symmetrically arranged at one end of the truck body 2. A tie rod 4 is fixedly connected between the upper parts of the two fixed frames 3. A tilting mechanism is provided between the frames 1, and a support mechanism is connected below the tilting mechanism. The support mechanism includes a slide rail 11, with several fixed blocks 12 on both sides of the slide rail 11 fixedly connected to one side of the frame 1. A sliding seat 14 is slidably installed inside the slide rail 11, and the sliding seat 14 is hingedly connected to the tilting mechanism via a support rod 13. The connection between the slide rail 11 and the fixed blocks 12 ensures the installation stability of the support mechanism. The hinged design between the sliding seat 14 and the support rod 13 allows the sliding seat 14 to slide flexibly within the slide rail 11 when the tilting mechanism moves, providing a basis for subsequent support and limiting.

[0016] In this example, the support mechanism also includes a rack 15, which is symmetrically arranged within the slide rail 11 and located on both sides of the slide block 14. A cavity 22 is provided inside the slide block 14, and a bidirectional telescopic rod 18 is fixedly installed within the cavity 22. Both telescopic ends of the bidirectional telescopic rod 18 extend to the outside of the slide block 14 and are connected to pawls 19. The pawls 19 are rotatably sleeved on the outside of the telescopic ends of the bidirectional telescopic rod 18, with the lower end of the pawls 19 meshing with the rack 15. A rotating sleeve 27 and a torsion spring 20 are sleeved on the outer walls of both telescopic ends of the bidirectional telescopic rod 18, with the rotating sleeve 27 positioned below the torsion spring 20. Inside, the rotating sleeve 27 is rotatably connected to the telescopic end of the bidirectional telescopic rod 18. The two ends of the torsion spring 20 are fixedly connected to the pawl 19 and the outer wall of the rotating sleeve 27, respectively. The outer wall of the slide 14 is symmetrically provided with storage grooves 21, and the storage grooves 21 correspond to the pawl 19. The meshing structure of the rack 15 and the pawl 19 can realize the one-way locking of the slide 14 when the hydraulic telescopic rod 10 fails. The cooperation between the bidirectional telescopic rod 18 and the torsion spring 20 enables the pawl 19 to automatically reset and tightly mesh with the rack 15. The storage groove 21 can store the pawl 19 in the non-locked state to avoid interfering with the normal movement of the flipping mechanism.

[0017] In this example, a limiting rod 26 is fixedly connected to one side of the outer wall of the rotating sleeve 27, and one end of the limiting rod 26 is in contact with the side wall of the storage groove 21 near the carriage 2. The limiting rod 26 is located on the side of the torsion spring 20 away from the pawl 19. The inner wall of the slide rail 11 is convex in shape. The top of the slide block 14 is provided with a groove 16. A connecting plate 17 is symmetrically provided in the groove 16. One end of the support rod 13 is located between the connecting plates 17, and the support rod 13 is hinged to the connecting plate 17. The slide rail 11 with its convex inner wall shape can prevent the slide block 14 from falling out and ensure the stability of the movement. The design of the groove 16 and the connecting plate 17 makes the hinge of the support rod 13 and the slide block 14 more stable, which is convenient for transmitting the driving force of the flipping mechanism. The setting of the limiting rod 26 can limit the pawl 19, so that when the slide block 14 moves to its initial position, the position of the pawl 19 is restricted and fixed, which improves the locking effect.

[0018] In this example, the tilting mechanism includes a rotating rod 5 located between two frames 1. Both ends of the rotating rod 5 are rotatably connected to the frames 1 on both sides. A fixing plate 6 is fixedly connected to the outer wall of the rotating rod 5. A support plate 7 is fixedly connected to the end of the fixing plate 6 away from the rotating rod 5. A fixing hook 8 is connected to the side of the support plate 7 near the fixing plate 6 through an adjustment assembly. Fixing rods 9 are fixedly installed symmetrically on both sides of the fixing plate 6. Hydraulic telescopic rods 10 are symmetrically provided on the outer side of the fixing plate 6. Both ends of the hydraulic telescopic rods 10 are hinged to the fixing rods 9 and the side wall of one side of the frame 1, respectively. The rotatable connection between the rotating rod 5 and the frame 1 allows the tilting mechanism to tilt flexibly. The combination of the fixing plate 6, the support plate 7, and the fixing hook 8 facilitates the traction and fixation of the carriage 2. The hydraulic telescopic rod 10 drives the tilting mechanism through the hinged fixing rods 9. The structure is compact and the driving force is uniform.

[0019] In this example, the adjustment component includes an adjustment plate 23, which is disposed on the side of the support plate 7 near the carriage 2. The upper side of the adjustment plate 23 is fixedly connected to the fixing hook 8. The sidewalls of the adjustment plate 23 and the fixing hole 24 are provided with a number of fixing holes 24 at equal intervals. The adjustment plate 23 and the support plate 7 are connected by a number of fixing bolts 25, and the fixing bolts 25 pass through the corresponding fixing holes 24 on the support plate 7 and the adjustment plate 23. By cooperating with the adjustment plate 23 and the fixing holes 24 on the support plate 7 at different positions, the height of the fixing hook 8 can be adjusted to adapt to carriages 2 of different heights, thereby improving the versatility and application range of the equipment.

[0020] In this example, the bottom of the fixed plate 6 is hinged to the upper end of the support rod 13. The fixed plate 6 and the support plate 7 are arranged vertically, and reinforcing plates are provided on both sides of the connection between the fixed plate 6 and the support plate 7. The hinged connection between the fixed plate 6 and the support rod 13 enables the support mechanism and the flipping mechanism to be linked. The vertically distributed fixed plate 6 and support plate 7 enhance the structural strength of the flipping mechanism, and the reinforcing plates further improve the deformation resistance of the connection, ensuring the stability of the overall structure.

[0021] During use, the hydraulic telescopic rod 10 drives the fixed plate 6 to rotate around the rotating rod 5, which in turn drives the fixed hook 8 to pull the carriage 2 to tilt. At the same time, the support rod 13 pulls the slide 14 to slide in the convex slide rail 11. At this time, the pawl 19, because its rotational direction is adapted to the movement direction, will not obstruct the movement of the rack 15, thus allowing it to slide along the rack 15. When the hydraulic telescopic rod 10 fails, the gravity of the carriage 2 causes the slide 14 to move in the opposite direction. The pawl 19 is locked in the groove between the rack 15. Under the action of the torsion spring 20, the limit rod 26 and the rotating sleeve 27, the slide 14 is locked, so that the support rod 13 and the fixed plate 6 form a triangular support to prevent the carriage 2 from falling back. In addition, by adjusting the plate 23 and cooperating with the fixing hole 24 of the support plate 7, the height of the fixed hook 8 can be adjusted to adapt to different carriages 2. The convex slide rail 11 on the inner wall and the reinforcing plate and other structures ensure the overall stability.

[0022] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
