Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment, and in particular to a new type of door opening and closing mechanism for a waste transfer container tilting platform. Background Technology

[0002] As the core equipment of waste transfer stations, the design of the inlet gate opening and closing mechanism of waste transfer containers directly affects the efficiency and safety of waste treatment.

[0003] In current mainstream waste compression and transfer processes, the rotating shaft of the inlet gate is generally located on the side away from the bottom beam of the container. This results in the gate being far from the bottom beam after opening, and the corresponding opening and closing mechanism is only suitable for this structure. However, in the vertical waste transfer process with flat inlet and flat outlet on the same side, to optimize spatial layout and operational convenience, the rotating shaft of the inlet gate is innovatively arranged on one side of the bottom beam of the container, so that the gate is close to the bottom beam after opening. This structural difference makes traditional opening and closing mechanisms unsuitable due to mismatched motion trajectories. Therefore, a special opening and closing mechanism adapted to this new type of container is urgently needed to achieve efficient and stable opening and closing of the inlet gate, and to meet the automation and safety requirements of the waste transfer process. Summary of the Invention

When the waste container is placed on the tipping platform and the two locking holes are respectively positioned opposite the two locking shafts, the drive assembly can drive the two locking shafts to slide closer to each other, so that one end of each locking shaft extends into the two locking holes.

[0007] In a preferred embodiment, the drive assembly includes two drive members, each of which is respectively connected to two locking shafts. Each drive member includes: A guide seat is mounted on the flipping platform, and the locking shaft is axially slidably mounted on the guide seat; A bushing, which is fixedly fitted onto the outside of the locking shaft by screws; A locking cylinder is provided, with one end hinged to the bushing and the other end hinged to the guide seat.

Two second limiting seats are provided on the top two sides of the lifting frame. When the tilting platform is in a horizontal state, the two second limiting seats abut against the two sides of the tilting platform.

[0011] A novel waste transfer station includes any of the aforementioned tipping mechanisms, and further includes: The foundation pit is located on the ground. A parking space is provided on one side of the pit opening for parking container hooklift trucks / garbage unloading trucks. The tilting mechanism is located inside the foundation pit. When the tilting platform is in a horizontal state, the tilting platform rises to the pit opening.

Figure 1-13 As shown, a preferred embodiment of a waste container tipping mechanism 3 is provided in a pit 1 for tipping a waste container 2 to a vertical or horizontal state. It includes a support frame 32, a lifting frame 33, at least one lifting cylinder 34, a tipping frame 39, a tipping platform 31, and at least one tipping cylinder 35. The lifting frame 33 is longitudinally slidably mounted on the support frame 32. The lifting cylinder 34 is connected between the lifting frame 33 and the support frame 32 to drive the lifting frame 33 to rise and fall. The tipping frame 39 is rotatably connected to the top of the lifting frame 33. The tipping platform 31 is connected to the top of the tipping frame 39. A locking mechanism 37 is provided on the tipping platform 31 to lock the waste container 2 onto the tipping platform 31. One end of the tipping cylinder 35 is hinged to the tipping frame 39, and the other end is hinged to the lifting frame 33 to drive the tipping frame 39 to rotate, so that the tipping platform 31 can switch between horizontal and vertical states.

[0023] In this embodiment, when the garbage container 2 is lowered into the pit 1, the empty garbage container 2 is placed horizontally on the tilting platform 31 located at the pit opening of the pit 1 by the transfer hook truck 8. The garbage container 2 is locked to the tilting platform 31 by the locking mechanism 37. The lifting cylinder 34 drives the lifting frame 33 to descend a certain distance. Then, the tilting cylinder 35 drives the tilting frame 39 to rotate so that the tilting platform 31 is tilted from the horizontal state to the vertical state. Then it is lowered again until the garbage container 2 is placed at the bottom of the pit 1. Once the garbage container 2 is full, the tilting platform 31 rises a certain distance and then tilts from a vertical position to a horizontal position. The tilting platform 31 continues to rise until the fully loaded garbage container 2 is raised to the opening of the pit 1, and then it is transported away by the transfer hooklift truck 8.

[0024] The flipping mechanism 3 used in this application, through a specific flipping action design, can effectively avoid spatial interference between the waste container 2 and the receiving mechanism (chute) at the pit opening of the foundation pit 1 during the transfer process, thereby improving the efficiency and safety of waste transfer and ensuring the stable operation of the entire waste treatment system.

[0025] Furthermore, the locking mechanism 37 includes at least two locking shafts 372, at least two locking holes 211, and a drive assembly. The two locking shafts 372 are slidably disposed on both sides of the tilting platform 31, and the two locking holes 211 are disposed on the bottom beam 21 on the side of the waste container 2 and are respectively located on both sides of the bottom beam 21. The drive assembly is connected to the two locking shafts 372 for driving the two locking shafts 372 to slide closer to each other or further away from each other. When the waste container 2 is placed on the tilting platform 31 and the two locking holes 211 are respectively positioned opposite the two locking shafts 372, the drive assembly can drive the two locking shafts 372 to slide closer to each other, so that one end of the two locking shafts 372 respectively extends into the two locking holes 211.

[0026] Specifically, when the waste container 2 of the overturning mechanism 3 is overturned and transferred, the locking shaft 372 in the locking mechanism 37 and the locking hole 211 on the bottom beam 21 of the waste container 2 lock together, which can improve the stability of the overturning action of the waste container 2.

[0027] Furthermore, the drive assembly includes two drive components, which are respectively connected to two locking shafts 372. Each drive component includes a guide seat 371, a bushing 373, and a locking cylinder 374. The guide seat 371 is mounted on the tilting platform 31, and the locking shaft 372 is axially slidably mounted on the guide seat 371. The bushing 373 is fixedly sleeved on the outside of the locking shaft 372 by screws. One end of the locking cylinder 374 is hinged to the bushing 373, and the other end is hinged to the guide seat 371. The locking shaft 372 slides axially by the extension and retraction of the locking cylinder 374.

[0028] It should be noted that the locking shaft 372 in this application is not limited to two. Several locking shafts 372 can be provided on both sides of the flipping platform 31, and multiple locking holes 211 are provided on the bottom beam 21 to further achieve the locking effect on the garbage container 2.

[0029] Furthermore, the top two sides of the support frame 32 are provided with sliding grooves, and the bottom two sides of the lifting frame 33 have two sliding parts 332. The two sliding parts 332 are longitudinally slidably connected and installed in the two sliding grooves. Each sliding part 332 is provided with a lifting cylinder 34 between it and the bottom of the sliding groove.

[0030] Furthermore, the lifting cylinder 34 is hinged between the sliding part 332 and the bottom of the groove.

[0031] More specifically, the bottom of the sliding part 332 extends upward to form an installation groove, and the lifting cylinder 34 is set in the installation groove. The end of the hydraulic rod of the lifting cylinder 34 is hinged to the bottom of the groove, and the top of the lifting cylinder 34 is hinged to the inner wall of the installation groove. The installation groove can reduce the minimum descent distance of the tilting platform 31 and also provide protection for the lifting cylinder 34.

[0032] Furthermore, two first limiting seats 341 are provided on both sides of the support frame 32. When the tilting platform 31 is in a vertical state, the two first limiting seats 341 respectively abut against the two sides of the tilting platform 31. Two second limiting seats 391 are provided on both sides of the top of the lifting frame 33, and two third limiting seats 331 are provided on both sides of the tilting frame 39. When the tilting platform 31 is in a horizontal state, the two second limiting seats 391 respectively abut against the two third limiting seats 331.

[0033] Each first limiting seat 341 includes a seat body and a limiting bolt. The seat body is mounted on the support frame 32, and the limiting bolt is threaded onto the seat body and can abut against the tilting platform 31 for limiting. The limiting bolt's limiting position on the tilting platform 31 can be adjusted by rotating it. The first limiting seat 341, the second limiting seat 391, and the third limiting seat 331 respectively limit the tilting platform 31 when it is in a vertical and horizontal state to prevent over-tilting and ensure safe operation of the equipment. The limiting bolt's adjustable limiting position improves the equipment's adaptability.

[0034] A novel waste transfer station includes any one of the aforementioned tilting mechanisms 3, and further includes: a pit 1 and a side beam 11. The pit 1 is located on the ground, and a parking space is provided on one side of the pit opening for parking a container hooklift truck 8 / waste unloading truck 9. The tilting mechanism 3 is located inside the pit 1. When the tilting platform 31 is in a horizontal state, the tilting platform 31 rises to the pit opening of the pit 1. The side beam 11 is located on the side of the pit opening of the pit 1, and the side beam 11 has support parts 12 that match the number of locking shafts 372. When the tilting platform 31 rises horizontally to the pit opening of the pit 1, and one end of each of the two locking shafts 372 disengages from the two locking holes 211, the other ends of the two locking shafts 372 are respectively supported on the top of the two support parts 12.

[0035] In this application, when the tilting platform 31 moves horizontally to the pit opening of the pit 1 to place the empty garbage container 2 or unlock and carry the fully loaded garbage container 2, the locking shaft 372 is supported on the top of the support part 12 so that the gravity of the tilting platform 31 is transferred to the side beam 11, which reduces the damage to the tilting mechanism 3 and increases the stability and safety of the garbage container 2 carrying operation.

[0036] Furthermore, the top of the support part 12 has a support groove 1211, which matches the other end of the locking shaft 372 and serves to limit the horizontal movement of the locking shaft 372, thereby improving the support stability of the support part 12 on the locking shaft 372.

[0037] Furthermore, the support part 12 includes two support blocks 121 and a support upper seat 122. The two support blocks 121 are arranged opposite each other and are supported on the side beam 11. Each of the two support blocks 121 has an upper support slope on its opposite top end. The support upper seat 122 has a support groove 1211 on its top and two lower support slopes on both sides of its bottom. The two lower support slopes contact the two upper support slopes respectively. By adjusting the distance between the two support blocks 121, the support height of the support upper seat 122 can be adjusted. Adjusting the distance between the support blocks 121 changes the height of the support upper seat 122, adapting to different working conditions and improving the equipment's versatility.

[0038] Furthermore, both ends of the tilting platform 31 are equipped with retractable safety platforms 38. When the tilting platform 31 is in a horizontal position at the opening of the pit 1, the safety platforms can extend outwards to fill the gap between the end of the safety platform and the inner wall of the pit opening 1. The safety platforms 38 fill the gap, preventing personnel from accidentally falling, ensuring the safety of workers, and improving equipment safety.

[0039] Based on the above, this utility model also has the following embodiments: Furthermore, as a preferred embodiment, the safety platform 38 has guide rails 381 on both sides, and the two guide rails 381 are slidably disposed on the bottom sides of the flip platform 31 respectively. A third drive structure 100 is provided between each safety platform 38 and the flip platform 31 to drive the safety platform 38 to extend outward or retract towards the bottom of the flip platform 31.

[0040] Furthermore, as a preferred embodiment, the third drive structure 100 includes: a fixed arm 101, two first swing arms 103, two second swing arms 105, and a telescopic cylinder 102. The fixed arm 101 is mounted on the tilting platform 31. One end of each of the two first swing arms 103 is hinged to both ends of the fixed arm 101. One end of each of the two second swing arms 105 is hinged to the safety platform 38, and the other end is hinged to the other end of each of the two first swing arms 103. A connecting arm 104 is hinged between the two hinge shafts formed at the hinge points of the other ends of the two first swing arms 103 and the other ends of the two second swing arms 105. One end of the telescopic cylinder 102 is hinged to the fixed arm 101, and the other end is hinged to the side wall of one of the first swing arms 103. The third drive structure 100 drives the safety platform 38 to automatically extend and retract, improving the degree of automation, reducing manual operation, and lowering labor intensity.

[0041] Furthermore, as a preferred embodiment, one end of the tilting platform 31 is also provided with a door opening and closing mechanism 36 for automatically opening or closing the door of the waste container 2. The door opening and closing mechanism 36 includes: two tilting arms 361, a limiting arm 364, two guide sleeves 362, a first drive structure 365, and a second drive structure 366. One end of each of the two tilting arms 361 is hinged to both sides of one end of the tilting platform 31, and the limiting arm 364 is connected to the other end of the two tilting arms 361. The two guide sleeves 364 are connected to the other end of the two tilting arms 361. 2. A sliding sleeve is provided on the outside of the limiting arm 364, and each guide sleeve 362 is provided with a hook 363. The first drive structure 365 is connected to the two guide sleeves 362 for driving the two guide sleeves 362 to slide closer or further apart from each other, so that the two hooks 363 are respectively attached to or detached from the two pins located on both sides of the opening and closing door of the garbage container 2. The second drive structure 366 is connected to the two flipping arms 361 for driving the flipping arms 361 to rotate outward to open or close the opening and closing door.

[0042] In this embodiment, during operation, the tilting platform 31 is in a horizontal state. The transfer hooklift truck 8 places the empty garbage container 2 horizontally on the tilting platform 31, and the opening and closing door of the garbage container 2 abuts against the limiting arm 364. At this time, the two hooks 363 are respectively positioned opposite the two pins on both sides of the opening and closing door. The first drive structure 365 drives the two guide sleeves 362 to slide closer to each other until the two hooks 363 are respectively fitted onto the outside of the two pins. At the same time, the tilting platform 31 tilts to a vertical state, and the garbage container 2 is set vertically. The second drive structure 366 drives the two tilting arms 361 to move outward. The side rotation causes the synchronous drive door to rotate outward to open the door, and the garbage unloading truck 9 begins to unload into the garbage container 2 until the garbage container 2 is full. Then, the second drive mechanism drives the tilting arm 361 to rotate in the opposite direction to close the door. The first drive structure 365 drives the two guide sleeves 362 to slide away from each other and causes the two hooks 363 to disengage from the two pins. At the same time, the tilting platform 31 tilts back to the horizontal state and drives the full-loaded garbage container 2 to the tilting platform 31. Then, the full-loaded garbage container 2 is carried away by the transfer hook arm truck 8.

[0043] In this embodiment, when the door is opened, the first drive structure 365 drives the guide sleeve 362 to move closer together, and the hook 363 hooks onto the pins on both sides of the door. The second drive structure 366 drives the tilting arm 361 to rotate outward, thereby opening the feeding door. When the door is closed, the second drive structure 366 drives the tilting arm 361 to rotate in the opposite direction, closing the feeding door. The first drive structure 365 drives the guide sleeve 362 to separate, and the hook 363 disengages from the pin. The modular design enables independent driving of the hook 363 and the tilting arm 361, adapting to the container structure where the rotating shaft is close to the bottom beam 21. This solves the motion interference problem of traditional mechanisms and improves the stability and compatibility of the door opening and closing actions.

[0044] Furthermore, as a preferred embodiment, the first drive structure 365 is a hydraulic cylinder connected between the two guide sleeves 362. The extension and retraction of the hydraulic cylinder directly drives the guide sleeves 362 to slide along the limiting arm 364, realizing the engagement and disengagement of the hook 363. The hydraulic drive provides stable thrust, ensuring precise engagement between the hook 363 and the pin, while simplifying the transmission structure and reducing the failure rate.

[0045] Even better, the two ends of the hydraulic cylinder are hinged to the two guide sleeves 362 respectively.

[0046] Furthermore, as a preferred embodiment, hinge seats 3662 are provided on both sides of one end of the tilting platform 31, and one end of the two tilting arms 361 is respectively hinged to the two hinge seats 3662. The tilting arms 361 rotate around the axis of the hinge seats 3662 to realize the opening and closing of the feed gate. The hinge design reduces motion friction, improves the rotation flexibility of the tilting arms 361, and extends the service life of the mechanism.

[0047] Furthermore, in a preferred embodiment, the second drive structure 366 includes two drive components, which are respectively connected to the two tilting arms 361. Each drive component includes a rocker arm 3663, a connecting rod 3664, and an opening / closing cylinder 3661. One end of the rocker arm 3663 is hinged to the hinge seat 3662, one end of the connecting rod 3664 is hinged to the tilting arm 361, and one end of the opening / closing cylinder 3661 is hinged to the tilting platform 31, while the other end is hinged to the other end of the rocker arm 3663 and the other end of the connecting rod 3664. In this application, the hinge seat 3662, rocker arm 3663, connecting rod 3664, and tilting arm 361 form a four-bar linkage 3664 mechanism, which realizes precise control of the motion trajectory, ensures consistent opening angle of the feed gate, and avoids jamming.

[0048] Furthermore, as a preferred embodiment, the rocker arm 3663 has an arc-shaped structure. The arc-shaped rocker arm 3663 maintains smooth contact with the connecting rod 3664 during rotation, optimizing the force transmission path, reducing stress concentration, and improving the load-bearing capacity of the mechanism.

[0049] Furthermore, as a preferred embodiment, the top of each tilting arm 361 is bent outward and connected to a limiting arm 364 to improve the space utilization of the tilting platform 31 for the waste container 2.

[0050] Furthermore, as a preferred embodiment, the flipping platform 31 has two guide rails 312, which are arranged in parallel. Each guide rail 312 is arranged along the length direction of the flipping platform 31, and the two guide rails 312 are respectively guided and cooperated with the bottom sides of the bottom beam 21.

[0051] Furthermore, as a preferred embodiment, each guide rail 312 is provided with a limit block 313 on the side near the door opening and closing mechanism 36. When the limit block 313 is engaged with one end of the bottom beam 21, the locking shaft 372 and the locking hole 211 are coaxially arranged. The guide rail 312 provides guidance for the waste container 2, ensuring that the container is accurately placed on the tipping platform 31; the limit block 313 makes the locking shaft 372 coaxial with the locking hole 211, which facilitates the accurate operation of the locking mechanism 37.

[0052] Furthermore, in a preferred embodiment, the tilting platform 31 has two guide blocks 311 located on the outer side of one end of the two guide rails 312 away from the limiting block 313. The minimum distance between the two guide blocks 311 matches the width of the bottom beam 21, and the top of the opposite ends of the two guide blocks 311 are provided with guide ramps. The guide blocks 311 further assist in the positioning of the waste container 2, and the guide ramps make the container placement smoother, improving the ease of operation of the equipment.

[0053] Furthermore, as a preferred embodiment, the novel waste transfer station also includes a support platform 5 located at the opening of the pit 1. The support platform 5 is equipped with a compactor 6 and an automatically tilting chute structure 7. The chute structure 7 is located on the side of the pit 1. When the waste unloading truck 9 unloads towards the vertical waste container 2, the chute structure 7 tilts down to the opening of the waste container 2 to facilitate waste unloading. After each unloading, the compactor 6 moves downward and presses down on the waste in the waste container 2 to compact it. It should be noted that the structure and operating principle of the compactor 6 and the chute structure 7 in this application are conventional technical means of existing waste transfer stations, and their structure and operating principle will not be described in detail here.

[0054] Furthermore, as a preferred embodiment, it also includes a container weighing platform 4 located in the pit 1. When the waste container 2 is vertically lowered into the pit 1 via the tilting platform 31, the bottom of the waste container 2 is supported on the container weighing platform 4.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
