Description

Technical Field

[0001] This utility model relates to a simple mechanical locking hook push-pull box device, specifically a simple mechanical locking hook push-pull box device, belonging to the technical field of waste compression equipment. Background Technology

[0002] The push-pull container device of a waste compactor is a core component of waste compression equipment. It primarily enables precise docking, secure locking, and efficient transfer between the waste collection container and the compactor unit, and is widely used in municipal solid waste transfer stations, industrial park waste treatment sites, and other similar applications. This device typically consists of a hydraulic drive system (including hydraulic cylinders, hydraulic pumps, and control valve groups), a mechanical push-pull mechanism (such as a telescopic arm and hook assembly), a guide and positioning assembly (side guide wheels and limit blocks), and a safety locking device.

[0003] The prior art patent application number is 201410701580.7, and the patent name is: a push-pull box device for a garbage compressor. It includes a drive cylinder and a push-pull hook. One end of the cylinder body of the drive cylinder is hinged to the cylinder body seat. The push rod of the drive cylinder and one end of the push-pull hook are hinged together. The other end of the push-pull hook is provided with a hook head formed by a groove with an upward opening. The feature is that it also includes a push-pull box body with openings at both ends. The push-pull box body is located in front of the drive cylinder. Both sides of the push-pull box body are provided with strip-shaped through holes extending along the extension and retraction direction of the push rod of the drive cylinder.

[0004] However, the existing box is only fixed by a single hook structure after being pulled back to the compression station, lacking auxiliary positioning or locking mechanisms, and cannot form a stable connection. This single connection method is easily affected by factors such as the weight fluctuation of the box itself, slight vibrations of the compression station, and inertial forces during the pulling process, which may lead to the risk of loosening, displacement, or even separation between the hook and the box. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a simple mechanical hook-type push-pull box device to solve the above-mentioned problems, so as to solve the problem that the existing technology uses a single hook structure for fixing, lacks auxiliary positioning or locking mechanisms, and cannot form a stable connection state.

[0006] This utility model is achieved through the following technical solution: a simple mechanical lock hook push-pull box device.

[0007] The device includes a base, a housing movably connected to the top of the base, a drag handle fixedly connected to the bottom of the housing, a support frame screwed to the top of the base, guide grooves on both sides of the support frame, and downward folding grooves on both sides of the support frame. The downward folding grooves are connected to the guide grooves. The base provides stable support for the overall structure, the movable connection of the housing facilitates position adjustment, the drag handle facilitates dragging the housing, and the guide grooves and downward folding grooves cooperate to guide the movement of related components and ensure the stability of the component's movement trajectory.

[0008] Preferably, a hydraulic cylinder is screwed to the top of the base. One end of the hydraulic cylinder passes through the support frame and extends to the inner side of the support frame. A mounting base is rotatably connected to one end of the hydraulic cylinder. Limiting rods are fixedly connected to both sides of the mounting base. The limiting rods extend to the inner side of the guide groove. The hydraulic cylinder can provide power to drive the mounting base to move, meeting the power requirements of the operation. The limiting rods cooperate with the guide groove to restrict the direction of movement of the mounting base, prevent it from deviating, and improve the accuracy of movement.

[0009] Preferably, two liquid storage cylinders are fixedly connected to the bottom of the inner cavity of the mounting base. The inner cavity of the liquid storage cylinder is filled with damping oil, and a sealing ring is bonded to the top of the liquid storage cylinder. A buffer spring is embedded in the inner cavity of the liquid storage cylinder. The damping oil and the buffer spring work together to play a good role in buffering and shock absorption, reducing the impact force when the parts move. The sealing ring can prevent the damping oil from leaking and ensure the stability of the buffering function of the liquid storage cylinder.

[0010] Preferably, a pressure rod is inserted into the top of the liquid storage cylinder, and the bottom end of the pressure rod penetrates the liquid storage cylinder and extends into the inner cavity of the liquid storage cylinder. A pressure plate is fixedly connected to the bottom end of the pressure rod, and a through hole is opened at the top of the pressure plate. The through holes are evenly distributed in sequence. The pressure rod can transmit external force to drive the pressure plate to move. The pressure plate, together with the damping oil, enhances the buffering effect. The through hole facilitates the flow of the damping oil, improves the buffering response speed, and ensures a smooth buffering process.

[0011] Preferably, a bent mounting bracket is fixedly connected to the top of the pressure rod, and three friction sleeves are fixedly connected to the top of the bent mounting bracket. The bent mounting bracket provides a stable mounting base for the friction sleeves, and the friction sleeves can increase the friction with other components, reduce the relative sliding of components, and improve the connection stability.

[0012] Preferably, three mounting plates are fixedly connected to the outer side of the liquid storage cylinder, and a friction rod is fixedly connected to the top of the mounting plate. The top end of the friction rod passes through the bent mounting frame, and the friction rod contacts the friction sleeve. The mounting plate provides reliable mounting support for the friction rod. The friction resistance generated by the contact between the friction rod and the friction sleeve can further slow down the movement speed of the component and enhance the buffering and positioning effect.

[0013] Preferably, a hook is fixedly connected between the tops of the two bent mounting brackets. The hook engages with the tow handle. A fixing frame is fixedly connected to one side of the hook. Three compression springs are fixedly connected to one side of the fixing frame. The engagement of the hook with the tow handle connects the housing and the drive component, facilitating the movement of the housing. The compression springs provide elastic pressure, enhancing the tightness of the connection between the hook and the tow handle.

[0014] Preferably, one end of the compression spring is fixedly connected to a limiting plate, one side of the limiting plate passes through the hook and extends above the tow handle, and the top and bottom of the limiting plate are provided with beveled edges. The limiting plate can limit the tow handle to prevent the hook from separating from the tow handle, ensuring stable connection. The beveled edges facilitate the tow handle to engage or disengage from the hook, improving ease of operation.

[0017] 2. This simple mechanical hook-locking push-pull box device, through a stable hook mechanism, can significantly improve the stability of the connection between the hook and the box body, reduce loosening or displacement caused by vibration, inertia and other factors during the push-pull process, and ensure the box body is accurately positioned during movement; the stable connection can avoid relative friction and collision between the box body and the hook, reduce component wear, and extend the service life of the equipment; in addition, the stable hook state can keep the box body stable during the push-pull process, reducing the spillage or damage of internal materials caused by shaking.

[0034] This utility model provides a simple mechanical lock hook push-pull box device.

[0035] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The device includes a base 1, a box 101 movably connected to the top of the base 1, a drag handle 102 fixedly connected to the bottom of the box 101, a support frame 2 screwed to the top of the base 1, guide grooves 201 and downward folding grooves 202 on both sides of the support frame 2, and the downward folding grooves 202 are connected to the guide grooves 201.

[0036] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A hydraulic cylinder 3 is screwed to the top of the base 1. One end of the hydraulic cylinder 3 passes through the support frame 2 and extends to the inside of the support frame 2. A mounting base 301 is rotatably connected to one end of the hydraulic cylinder 3. Limiting rods 302 are fixedly connected to both sides of the mounting base 301. The limiting rods 302 extend to the inside of the guide groove 201. Two liquid storage cylinders 4 are fixedly connected to the bottom of the inner cavity of the mounting base 301. The inner cavity of the liquid storage cylinders 4 is filled with damping oil 401. A sealing ring 402 is bonded to the top of the liquid storage cylinders 4. A buffer spring 403 is embedded in the inner cavity of the liquid storage cylinders 4. A pressure rod 5 is inserted into the top of the liquid storage cylinders 4. The bottom end of the pressure rod 5 penetrates through the liquid storage cylinder 4 and extends into the inner cavity of the liquid storage cylinder 4. The bottom end of the pressure rod 5 is fixedly connected to a pressure plate 501. The top end of the pressure plate 501 is provided with a through hole 502, and the through holes 502 are evenly distributed in sequence. The top end of the pressure rod 5 is fixedly connected to a bending mounting bracket 6. The top of the bending mounting bracket 6 is fixedly connected to three friction sleeves 601. The outside of the liquid storage cylinder 4 is fixedly connected to three mounting plates 7. The top of the mounting plate 7 is fixedly connected to a friction rod 701. The top end of the friction rod 701 penetrates through the bending mounting bracket 6, and the friction rod 701 is in contact with the friction sleeve 601.

[0037] Buffering and shock absorption for stability: During the push-pull movement of the hook head 8 and the housing 101, if an instantaneous impact force is generated due to inertia and vibration, the impact force will be transmitted to the pressure rod 5 through the bending mounting bracket 6. The pressure rod 5 pushes the pressure plate 501 at the bottom end to move into the inner cavity of the liquid storage cylinder 4. When the pressure plate 501 moves, on the one hand, it compresses the buffer spring 403 in the liquid storage cylinder 4, and the buffer spring 403 absorbs part of the impact force through elastic deformation; on the other hand, the pressure plate 501 squeezes the damping oil 401 in the liquid storage cylinder 4. The damping oil 401 needs to flow slowly through the through hole 502 of the pressure plate 501 to form damping resistance, reduce the moving speed of the pressure plate 501, and thus convert the instantaneous impact force into a smooth force transmission, preventing the hook head 8 and the tow handle 102 from loosening due to impact. At the same time, the sealing ring 402 at the top of the liquid storage cylinder 4 can prevent the damping oil 401 from being released. 1. Leakage prevention and ensuring continuous and stable buffering function and friction limit stability: When the pressure rod 5 moves slightly up and down with the impact force, the bending mounting bracket 6 at the top of the pressure rod 5 will synchronously drive the friction sleeve 601 to move. The friction sleeve 601 and the friction rod 701 fixed on the mounting plate 7 always maintain contact. The sliding friction generated when the two move relative to each other can further limit the swaying amplitude of the bending mounting bracket 6 and reduce the displacement deviation of the hook head 8. At the same time, the friction resistance can slow down the movement speed of the bending mounting bracket 6 and prevent the hook head 8 from shifting its engagement position with the towing handle 102 due to rapid swaying. Combined with the precise guiding effect of the limit rods 302 on both sides of the mounting base 301 moving along the guide groove 201, the locking hook mechanism is ensured to remain stable during operation from the three aspects of "buffering plus friction plus guidance", avoiding loosening or displacement of the connection.

[0038] Example 2, please refer to again. Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 A hook 8 is fixedly connected between the tops of the two bent mounting brackets 6. The hook 8 is snapped into the tow handle 102. A fixing bracket 801 is fixedly connected to one side of the hook 8. Three compression springs 802 are fixedly connected to one side of the fixing bracket 801. A limit plate 9 is fixedly connected to one end of the compression spring 802. One side of the limit plate 9 passes through the hook 8 and extends to the top of the tow handle 102. The top and bottom of the limit plate 9 are provided with beveled edges 901.

[0039] Connection Start-up Phase: When it is necessary to connect the housing 101, the hydraulic cylinder 3 provides power to push the mounting base 301 to move. The mounting base 301, through the pressure rod 5 and the bending mounting bracket 6, drives the hook head 8 to approach the tow handle 102. When the tow handle 102 contacts the inclined edge 901 at the bottom of the limiting plate 9, the inclined edge 901 is squeezed and generates a guiding effect, pushing the limiting plate 9 to move towards the fixing bracket 801. At the same time, the compression spring 802 is compressed. Locking Phase: As the hook head 8 continues to move, the tow handle 102 smoothly enters the locking groove of the hook head 8. When the tow handle 102 is fully engaged, the limiting plate 9 is no longer squeezed, the compression spring 802 releases its elastic potential energy, and pushes the limiting plate 9 to reset, with one side extending to the tow handle 102. Above 2, a mechanical limit is formed to prevent the tow handle 102 from disengaging from the hook head 8, thus completing the mechanical locking of the box 101 and the locking hook mechanism. Push-pull drive stage: After locking, the hydraulic cylinder 3 can drive the mounting base 301 to move along the guide groove 201 of the support frame 2 through extension and retraction. The mounting base 301 pulls or pushes the tow handle 102 in sequence through the pressure rod 5, the bending mounting frame 6, and the hook head 8, thereby driving the box 101 to move on the top of the base 1, realizing the push-pull operation of the box 101. If it is necessary to separate the box 101, the hydraulic cylinder 3 is driven in the opposite direction to make the hook head 8 move away from the tow handle 102. The tow handle 102 squeezes the inclined edge 901 on the top of the limiting plate 9, which can push the limiting plate 9 to move and disengage from the locked state, realizing the separation of the two.

[0040] Working Principle: Connection Start-up Stage: When the housing 101 needs to be connected, the hydraulic cylinder 3 provides power to push the mounting base 301 to move. The mounting base 301, through the pressure rod 5 and the bending mounting bracket 6, drives the hook head 8 to approach the tow handle 102. When the tow handle 102 contacts the inclined edge 901 at the bottom of the limiting plate 9, the inclined edge 901 is squeezed and generates a guiding effect, pushing the limiting plate 9 towards the fixing bracket 801. At the same time, the compression spring 802 is compressed. Locking Stage: As the hook head 8 continues to move, the tow handle 102 smoothly enters the locking groove of the hook head 8. When the tow handle 102 is fully locked in, the limiting plate 9 is no longer squeezed, and the compression spring 802 releases its elastic potential energy, pushing... The limiting plate 9 resets, extending one side above the tow handle 102 to form a mechanical limit, preventing the tow handle 102 from disengaging from the hook head 8, thus completing the mechanical locking of the housing 101 and the locking hook mechanism. In the push-pull drive phase: after locking, the hydraulic cylinder 3 can extend and retract to move the mounting base 301 along the guide groove 201 of the support frame 2. The mounting base 301 sequentially pulls or pushes the tow handle 102 via the pressure rod 5, the bent mounting frame 6, and the hook head 8, thereby moving the housing 101 on top of the base 1, achieving the push-pull operation of the housing 101. If it is necessary to separate the housing 101, the hydraulic cylinder 3 is driven in the reverse direction to move the hook head 8 away from the tow handle 102, causing the tow handle 102 to press against the inclined plate at the top of the limiting plate 9. When the edge 901 is engaged, the limiting plate 9 can be moved and released from the locked state, achieving separation of the two and providing buffering, shock absorption, and stability: During the push-pull movement of the box 101 driven by the hook 8, if an instantaneous impact force is generated due to inertia and vibration, the impact force will be transmitted to the pressure rod 5 through the bending mounting bracket 6. The pressure rod 5 pushes the pressure plate 501 at the bottom end to move into the inner cavity of the liquid storage cylinder 4. When the pressure plate 501 moves, on the one hand, it compresses the buffer spring 403 in the liquid storage cylinder 4, and the buffer spring 403 absorbs part of the impact force through elastic deformation; on the other hand, the pressure plate 501 squeezes the damping oil 401 in the liquid storage cylinder 4. The damping oil 401 needs to flow slowly through the through hole 502 of the pressure plate 501 to form damping resistance. The force reduces the moving speed of the pressure plate 501, thereby converting the instantaneous impact force into a smooth force transmission, preventing the hook head 8 and the tow handle 102 from loosening due to the impact. At the same time, the sealing ring 402 at the top of the liquid storage cylinder 4 can prevent the damping oil 401 from leaking, ensuring the continuous stability of the buffer function and stable friction limit: when the pressure rod 5 moves up and down slightly with the impact force, the bending mounting bracket 6 at the top of the pressure rod 5 will drive the friction sleeve 601 to move synchronously. The friction sleeve 601 and the friction rod 701 fixed on the mounting plate 7 always maintain contact. The sliding friction generated when the two move relative to each other can further limit the swaying amplitude of the bending mounting bracket 6 and reduce the displacement deviation of the hook head 8.Meanwhile, frictional resistance slows down the movement speed of the bending mounting bracket 6, preventing the hook head 8 from shifting its engagement position with the tow handle 102 due to rapid shaking. Combined with the precise guiding effect of the limiting rods 302 on both sides of the mounting base 301 moving along the guide groove 201, this combination of buffering, friction, and guidance ensures that the locking hook mechanism remains stable during operation, preventing loosening or displacement.
