Description

Technical Field

[0001] The utility model relates to the technical field of garbage transfer stations, in particular to a platform support leg for a high - safety turnover and displacement mechanism. Background Art

[0002] At present, there are usually two situations in the industry where vertical transfer stations adopt turnover and displacement mechanisms. First, the turnover and displacement mechanism does not have an additional support leg structure. When the displacement mechanism is turned to the horizontal state, the position of the displacement mechanism is locked by relying on the self - locking of the turning hinge point and the turning hydraulic cylinder. In this scheme, when the hook - arm vehicle backs and places the container, especially when the container is full of garbage, the impact of the container on the displacement mechanism is relatively large. Therefore, the load on the hydraulic cylinder is large, the working conditions are complex, and it affects its service life. Second, both sides of the turnover and displacement mechanism are provided with telescopic support legs. The support legs are usually round optical axes. When the round optical axis support legs support at the pit mouth, due to human misoperation, the round optical axis can still retract, and there is a risk that the displacement mechanism will accidentally lose support. Summary of the Invention

[0003] Aiming at the above problems existing in the existing turnover and displacement mechanism, the present invention aims to provide a platform support leg for a high - safety turnover and displacement mechanism.

[0004] The specific technical solution is as follows:

[0005] A platform support leg for a high - safety turnover and displacement mechanism, which is used to support the turnover platform of the turnover and displacement mechanism at the pit mouth of the foundation pit, includes: at least two support components, the two support components are respectively arranged on both sides of the turnover platform, and each support component includes:

[0006] A fixed leg, which is connected to the turnover platform;

[0007] A telescopic leg, one end of the telescopic leg is slidably arranged in the fixed leg, and the other end of the telescopic leg has a lock hole;

[0008] A lock post, which is installed at the pit mouth of the foundation pit;

[0009] A hydraulic cylinder, which is arranged in the fixed leg and is in transmission connection with the telescopic leg, and is used to drive the telescopic leg to telescopically slide relative to the fixed leg. When the telescopic leg extends outwards and supports at the pit mouth of the foundation pit, the lock post extends into the lock hole and is in locking cooperation with the lock hole.

[0010] As a further improvement and optimization of this scheme, the lock hole is arranged at the bottom of the other end of the telescopic leg.

[0011] As a further improvement and optimization of the present solution, each of the support components further includes a support steel plate, the support steel plate is installed at the pit mouth of the foundation pit, and the locking column is connected to the support steel plate.

[0012] As a further improvement and optimization of this solution, the supporting steel plate is buried in the concrete at the opening of the foundation pit.

[0013] As a further improvement and optimization of the present solution, each of the support components further includes a state sensor for sensing the telescopic state of the telescopic leg.

[0014] As a further improvement and optimization of the present solution, the state sensor includes a sensing block, a first sensor and a second sensor. The sensing block is arranged on the telescopic leg, and the first sensor and the second sensor are arranged on the fixed leg and are arranged sequentially along the axial direction of the fixed leg. When the sensing block cooperates with the first sensor, the telescopic leg is in an extended state, and when the sensing block cooperates with the second sensor, the telescopic leg is in a retracted state.

[0015] As a further improvement and optimization of the present solution, the cross-sections of the telescopic legs and the fixed legs are both rectangular structures.

[0016] Compared with the prior art, the above technical solution has the following positive effects:

[0017] (1) In the utility model, when the telescopic legs are extended to support the pit mouth of the foundation pit, the locking column is straightened into the locking hole to achieve a mechanical locking effect on the telescopic legs, effectively preventing the telescopic legs from retracting due to human error. The structure is simple and reliable, and the safety of the displacement mechanism is greatly improved.

[0018] (2) The supporting legs of the utility model have a simple structure and low processing and manufacturing cost, and the telescopic legs are driven by hydraulic cylinders to extend and retract, and the movement is stable and reliable.

[0019] (3) Each support assembly in the present invention also includes a status sensor for sensing the telescopic status of the telescopic leg; it is possible to know in real time whether the telescopic leg is in the extended state or the retracted state. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 14 This is a schematic structural diagram of a switch door mechanism of a turning and positioning mechanism for a garbage transfer station of the present utility model and a vertical garbage transfer station with the same. Figure 15 This is a schematic structural diagram of a switch door mechanism of a turning and positioning mechanism for a garbage transfer station of the present utility model and a vertical garbage transfer station with the same when opening the box cover, as Figures 1 to 15 shown, showing a turning and positioning mechanism 3 for a garbage transfer station of a preferred embodiment, including a frame 35, a turning platform 31, a sliding lifting mechanism 33, a switch door mechanism 34 and support legs 32. The frame 35 is installed in the foundation pit 1 of the garbage transfer station. One side of the turning platform 31 is hinged to the frame 35 and can be operably turned to a horizontal state and a vertical state. The sliding lifting mechanism 33 is arranged on the turning platform 31. When the turning platform 31 is in the horizontal state, the sliding lifting mechanism 33 is used to lock the empty garbage container 2 at the pit mouth of the foundation pit 1 and pull the empty garbage container 2 onto the turning platform 31, or to push the full garbage container 2 on the turning platform 31 away to the pit mouth of the foundation pit 1; when the turning platform 31 is in the vertical state, the sliding lifting mechanism 33 is used to lower the empty garbage solvent onto the support platform 11 in the foundation pit 1, or to lock the full garbage air on the support platform 11 and lift it onto the turning platform 31. The switch door mechanism 34 is arranged on the turning platform 31 and is used to automatically open the empty garbage container 2 located on the support platform 11, or to automatically close the full garbage container 2 located on the support platform 11. The support legs 32 are installed on the other side of the turning platform 31 and can be telescopically arranged to support to one side of the pit mouth of the foundation pit 1.

[0053] Preferably, the garbage container 2 is provided with an opening at one end. A lid 21 is hinged to match the opening of the garbage container 2. A pair of front wheels 22 and several pairs of auxiliary wheels 23 are provided on one side of the garbage container 2.

[0054] During the specific operation of this embodiment, the hook-arm vehicle 7 places the empty garbage container 2 on the tipping platform 31. The sliding lifting mechanism 33 locks the garbage container 2 and fully pulls it onto the tipping platform 31. Then, the tipping platform 31 rotates from the horizontal state to the vertical state, and the garbage container 2 is positioned directly above the support table 11. The sliding lifting mechanism 33 lowers the garbage container 2 onto the support table 11, and the lid 21 of the garbage container 2 is automatically opened by the door-opening mechanism 34. At this time, the garbage container 2 can collect garbage. After the garbage container 2 is full, the door-opening mechanism 34 automatically closes the lid 21 again. The sliding lifting mechanism 33 pulls up the full garbage container 2 and detaches it from the support table 11. The tipping platform 31 rotates and switches from the vertical state to the horizontal turntable. The sliding lifting mechanism 33 pushes the full garbage container 2 out to the opening of the foundation pit 1 and unlocks the lock on the garbage container 2. The hook-arm vehicle 7 picks up the full garbage container 2 for transportation.

[0055] Preferably, the garbage container 2 is provided with an opening at one end. A lid 21 is hinged to match the opening of the garbage container 2. A pair of front wheels 22 and several pairs of auxiliary wheels 23 are provided on one side of the garbage container 2, which facilitates the pushing and pulling movement of the garbage container 2 on the tipping platform 31.

[0056] In this embodiment, from the placement of the empty garbage container 2 on the tipping and positioning mechanism 3 to the container being filled with garbage, and then the hook-arm vehicle 7 picking up the full garbage container 2 from the positioning mechanism, the whole process does not require manual intervention and is autonomously completed by the tipping and positioning mechanism 3. The labor intensity of workers is low, and the automation degree is high. Moreover, when the garbage container 2 is collecting and compacting garbage, its gravity and pressure act on the support table 11, which improves the service life of the equipment.

[0057] In this embodiment, when the garbage container 2 falls onto the support table in the vertical state or separates from the container support table, there is no horizontal friction force between the container and the support table, which reduces the power requirement for the tipping and positioning mechanism 3. At the same time, it also reduces the wear of the garbage container 2 and improves its service life.

[0058] Further, as Figures 9 - 11As shown in the figure, the sliding and lifting mechanism 33 includes at least two guide rails 331, a sliding and lifting seat 332, a driving component, and a locking component. The two guide rails 331 are respectively connected to both sides of the flipping platform 31. The two ends of the sliding and lifting seat 332 are respectively slidably connected to the two guide rails 331. The driving component is in transmission connection with the sliding and lifting seat, and is used to drive the sliding and lifting seat 332 to slide along the two guide rails 331. The locking component is arranged on the sliding and lifting seat and can operably lock the garbage container 2. When the locking component locks the garbage container 2, the driving component can be used to drive the sliding and lifting seat 332 to slide, so as to pull or push the garbage container 2 to or away from the flipping platform 31.

[0059] In actual operation of this embodiment, the empty garbage container 2 is placed on the flipping platform 31. The locking component locks the container. The driving component drives the sliding and lifting seat 332 to slide on the two guide rails 331, and completely pulls the empty garbage container 2 onto the flipping platform 31. The flipping platform 31 flips to the vertical state. The driving component then drives the sliding and lifting seat 332 to descend until the empty garbage container 2 is driven to descend onto the support platform 11. After the garbage container 2 is full, the driving component drives the sliding and lifting seat 332 to rise until the full garbage container 2 is separated from the support platform 11 and completely pulled onto the flipping platform 31. The flipping platform 31 flips to the horizontal state. Finally, the driving component drives the sliding and lifting seat 332 to slide, and pushes the full garbage container 2 out to the edge of the foundation pit 1, and finally it is lifted and transported by the hook arm vehicle 7.

[0060] In this embodiment, when the garbage container 2 falls to or separates from the container support platform in the vertical state, there is no horizontal friction force between the container and the support platform, which reduces the power requirement for the flipping and displacement mechanism 3, and also reduces the wear of the garbage container 2 and improves its service life.

[0061] In this embodiment, after the container falls on the support platform, when the ram of the compactor 5 compacts the garbage in the garbage container 2, its acting force is directly transmitted to the support platform through the container, and the function of the sliding and lifting mechanism 33 greatly reduces the relative installation accuracy of the flipping and displacement mechanism 3 and the container support platform.

[0062] Furthermore, the locking component includes at least two lock box shafts 334 and at least two lock box oil cylinders 333. The two lock box shafts 334 are respectively slidably arranged on both sides of the sliding and lifting seat 332. The two lock box oil cylinders 333 are respectively installed on both sides of the sliding and lifting seat 332 and are respectively in transmission connection with the two lock box shafts 334, and are used to drive the two lock box shafts 334 to slide towards or away from each other, so that the two lock box shafts 334 respectively extend into or disengage from the two locking holes 24 located on both sides of the garbage container 2.

[0063] More preferably, the driving component includes at least two pulling oil cylinders 335. The two pulling oil cylinders 335 are connected to the flipping platform 31 and are respectively in transmission connection with both sides of the sliding and lifting seat 332.

[0064] Preferably, in order to facilitate the locking assembly to accurately lock the garbage container 2, a movable wheel stopper 336 is further connected to the sliding lifting seat. The movable wheel stopper 336 is arranged at the rear side of the sliding lifting seat. The sliding wheel stopper has two wheel grooves 3361 for respectively positioning the two front wheels 22 of the garbage container 2. When the two front wheels 22 are respectively in positioning cooperation with the two wheel grooves 3361, the two lock box shafts 334 are respectively arranged opposite to the two locking holes 24 on both sides of the garbage container 2.

[0065] Furthermore, guide sleeves 3321 are respectively arranged on both sides of the sliding lifting seat, and the two guide sleeves 3321 are respectively sleeved outside the two guide rails 331 in a sliding manner.

[0066] Furthermore, in order to reduce the friction between the guide sleeve 3321 and the guide rail 331 and improve the sliding effect between the guide sleeve 3321 and the guide rail 331, a roller 3321c is rotatably arranged at the top and bottom of each guide sleeve 3321, and the roller 3321c is in rolling cooperation with the top / bottom of the guide rail 331.

[0067] Furthermore, in order to improve the rotation effect of the roller 3321c when the guide sleeve 3321 slides on the guide rail 331, a roller shaft is coaxially arranged inside each roller 3321c, and the roller 3321c is rotatably arranged outside the roller shaft through a bearing 3321d, and the roller shaft is connected to the guide sleeve 3321.

[0068] Furthermore, there are two bearings 3321d, which are respectively arranged at both ends of the roller shaft. A lubricating oil cavity is formed among the two bearings 3321d, the roller 3321c and the roller shaft. One end of the roller shaft has an oil injection channel 3321e communicated with the lubricating oil cavity, and a grease nipple 3321f is arranged at the opening of the oil injection channel 3321e.

[0069] Furthermore, thread seats 3321a are respectively arranged on both sides of each guide sleeve 3321, and a guide block 3321b is threadedly connected to the opposite end faces of the two thread seats 3321a, and the guide block 3321b contacts the side surface of the guide rail 331.

[0070] Furthermore, as Figures 12 - 13As shown, the support leg 32 includes at least two support assemblies, which are respectively arranged on both sides of the flip platform 31, each support assembly includes a fixed leg 321, a telescopic leg 322, a locking column 323 and a hydraulic cylinder 325. The fixed leg 321 is connected to the flip platform 31, one end of the telescopic leg 322 is slidably arranged in the fixed leg 321, and the other end of the telescopic leg 322 has a locking hole 3221. The locking column is installed at the pit mouth of the foundation pit 1. The hydraulic cylinder 325 is arranged in the fixed leg 321 and is transmission-connected with the telescopic leg 322 for driving the telescopic leg 322 to telescope and slide relative to the fixed leg 321. When the telescopic leg 322 extends outward and is supported to the pit mouth of the foundation pit 1, the locking column 323 extends into the locking hole 3221 and is locked with the locking hole 3221.

[0071] In this embodiment, the supporting leg 32 has a simple structure and low manufacturing cost, and the telescopic leg 322 is driven by the hydraulic cylinder 325 to extend and retract, and the movement is stable and reliable.

[0072] In the present embodiment, when the telescopic leg 322 is extended to support the pit mouth of the foundation pit 1, the locking column 323 is straightened into the locking hole 3221 to achieve a mechanical locking effect on the telescopic leg 322, effectively preventing the telescopic leg 322 from retracting due to human error. The structure is simple and reliable, and the safety of the displacement mechanism is greatly improved.

[0073] Further, the locking hole 3221 is provided at the bottom of the other end of the telescopic leg 322;

[0074] Furthermore, each support assembly further includes a support steel plate 324, the support steel plate 324 is installed at the pit mouth of the foundation pit 1, and the locking column 323 is connected to the support steel plate 324;

[0075] Furthermore, the support steel plate 324 is buried in the concrete at the opening of the foundation pit 1;

[0076] Furthermore, each supporting component also includes a state sensor for sensing the telescopic state of the telescopic leg 322; it is possible to know in real time whether the telescopic leg 322 is in an extended state or a retracted state.

[0077] Furthermore, the state sensor includes a sensing block 327, a first sensor 326, and a second sensor 328. The sensing block 327 is disposed on the telescopic leg 322, and the first sensor 326 and the second sensor 328 are disposed on the fixed leg 321, and are sequentially disposed along the axial direction of the fixed leg 321. When the sensing block 327 and the first sensor 326 are inductively matched, the telescopic leg 322 is in an extended state, and when the sensing block 327 and the second sensor 328 are inductively matched, the telescopic leg 322 is in a contracted state.

[0078] The cross sections of the telescopic legs 322 and the fixed legs 321 are both rectangular structures.

[0079] Further, as Figures 14 - 15 shown, the door opening and closing mechanism 34 includes: a fixed frame 341, a flipping frame 342, two guide sleeves 343, a first driving component and a second driving component. The fixed frame 341 is installed on the flipping platform 31. The flipping frame 342 is a frame-shaped structure and is rotatably arranged on the fixed frame 341. The two guide sleeves 343 are respectively slidably arranged on both sides of the flipping frame 342. A door opening and closing hook 346 is arranged on each guide sleeve 343. The two door opening and closing hooks 346 respectively match with two lid hooks on both sides of the lid 21 of the trash container 2. The first driving component is in transmission connection with the two guide sleeves 343 and is used to drive the two guide sleeves 343 to slide on the flipping frame 342 so that the two door opening and closing hooks 346 respectively hook with the two lid hooks. The second driving component is in transmission connection with the flipping frame 342 and is used to drive the flipping frame 342 to rotate so as to open or close the lid 21.

[0080] In this embodiment, the container door opening and closing mechanism 34 is integrated on the flipping platform 31 of the container displacement mechanism, with a simple structure, small occupied space and reliable operation.

[0081] In this embodiment, the door opening and closing action of the trash container 2 is automatically completed without manual participation. The operator is far away from the opening of the foundation pit 1, reducing the labor intensity of the operator and providing safety at the same time.

[0082] In this embodiment, the flipping axis of the flipping frame 342 substantially coincides with the flipping axis of the lid 21 of the trash container 2, improving the smoothness when the container door is opened and closed.

[0083] Further, the door opening and closing hook 346 is an "L" shaped structure;

[0084] Further, the first driving component includes two push-pull oil cylinders 344. The two push-pull oil cylinders 344 are connected to the flipping frame 342 and are respectively in transmission connection with the two guide sleeves 343;

[0085] Further, the second driving component includes two flipping oil cylinders 345. The two flipping oil cylinders 345 are respectively arranged on both sides of the flipping frame 342, and the two flipping oil cylinders 345 are hinged on the fixed frame 341. The output ends of the two flipping oil cylinders 345 are respectively hinged to both sides of the flipping frame 342;

[0086] Further, the fixed frame 341 includes two triangular frames 3411. The two triangular frames 3411 are connected to the flipping platform 31. The flipping frame 342 is rotatably arranged between the two triangular frames 3411. The two flipping cylinders are respectively connected to the two triangular frames 3411;

[0087] Further, a cross bar 3412 is connected to the tops of the two triangular frames 3411.

[0088] Further, the turning and displacement mechanism 3 further includes a lifting oil cylinder 36. One end of the lifting oil cylinder 36 is hinged to the frame 35, and the other end is hinged to the turning platform 31, and is used to drive the turning platform 31 to turn.

[0089] As Figures 1 - 2 shown, a vertical garbage transfer station with a turning and displacement mechanism 3 includes the turning and displacement mechanism 3 for a garbage transfer station according to any one of the above, and further includes an equipment support platform 4 installed at the pit mouth of the foundation pit 1. A compactor 5 and a receiving mechanism 6 are installed on the equipment support platform 4; wherein, there are multiple collection positions in the foundation pit 1, and a support table 11 for supporting the garbage container 2 is provided at each collection position, and a plurality of turning and displacement mechanisms 3 are correspondingly provided; the compactor 5 can be operably moved between multiple collection positions to compact the garbage in the garbage container 2, and the operation trajectory of the compactor 5 does not interfere with the operation trajectory of each turning and displacement mechanism 3. The compactor 5 moves to directly above the corresponding garbage container 2, and then moves down to compact the garbage in the corresponding garbage container 2; the receiving mechanism 6 is used to receive the garbage transported by the garbage collection vehicle 8 on the other side of the pit mouth of the foundation pit 1 and centrally put it into the corresponding garbage container 2.

[0090] Further, the receiving mechanism includes hoppers whose quantity matches the quantity of the collection positions. The hoppers are rotatably arranged on the equipment support platform 4 and can be operably in a vertical state and a horizontal state. When the garbage container 2 at a collection position is lowered into the foundation pit 1 and the box cover 21 is opened through the automatic door opening and closing mechanism 34, the hopper rotates to the horizontal state, and the garbage collection vehicle 8 can unload garbage into the garbage container 2 through the hopper.

[0091] Further, the transfer station further includes an electrical system and a hydraulic system for realizing each operation action.

[0092] The specific working process of this embodiment is as follows:

[0093] S1. The hook arm vehicle 7 places the empty container on the turning platform 31 of the turning and displacement mechanism 3;

[0094] S2. The sliding jacking mechanism 33 of the turning and displacement mechanism 3 locks the container and the turning platform 31, and then completely pulls the container onto the turning platform 31;

[0095] S3. The lifting oil cylinder 36 of the turning and displacement mechanism 3 extends, and the turning platform 31 is turned up by a certain angle until the platform support leg 32 leaves the pit mouth of the foundation pit 1, and then the telescopic leg 322 retracts;

[0096] S4. The lifting oil cylinder 36 of the turning and displacement mechanism 3 retracts, the turning platform 31 rotates to the vertical state, and the container is turned to the vertical state;

[0097] S5. The slip-lifting mechanism 33 of the turnover and positioning mechanism 3 descends, causing the container to fall vertically until it lands steadily on the support platform.

[0098] S6. The door-opening and -closing mechanism 34 on the turnover and positioning mechanism 3 functions to automatically open the box cover 21.

[0099] S7. The material-receiving mechanism 6 turns downward to dock with the mouth of the container.

[0100] S8. The garbage collection vehicle 8 unloads the garbage into the container.

[0101] S9. The compactor 5 compacts the garbage until the container is filled with garbage.

[0102] S10. The material-receiving mechanism 6 turns upward.

[0103] S11. The door-opening and -closing mechanism 34 on the turnover and positioning mechanism 3 functions to automatically close the box cover 21.

[0104] S12. The slip-lifting mechanism 33 on the turnover and positioning mechanism 3 rises, causing the garbage-filled container 2 to disengage from the container support platform.

[0105] S13. The lifting oil cylinder 36 of the turnover and positioning mechanism 3 extends, and the garbage container 2 is turned upward to the horizontal state and then continues to turn upward by a small angle.

[0106] S14. After the telescopic leg 322 of the platform support leg 32 extends, the garbage container 2 slowly descends until the telescopic leg 322 touches the mouth of the foundation pit 1. At this time, the garbage container 2 is in the horizontal state.

[0107] S15. The slip-lifting mechanism 33 pushes the container to the mouth of the foundation pit 1.

[0108] S16. The slip-lifting mechanism 33 releases the locking of the garbage container 2 and the turnover platform 31.

[0109] S17. The hook-arm vehicle 7 picks up the container and transports the garbage.

[0110] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
