[0034] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] The positioner of the present invention will be described below with reference to the accompanying drawings.

[0036] The utility model provides a positioner, such as Figure 1 and Figure 4 As shown, the positioner includes:

[0037] The main body mechanism includes a fixed derrick platform 11 and a movable frame assembly movably arranged on the derrick platform 11, and the movable frame assembly is provided with an action driving element for driving the garbage bin to move; and

[0038] The reversing control valve group 2 includes a movable integrated valve block 21 arranged on the movable frame assembly and a fixed integrated valve block 22 arranged on the derrick platform 11 . The fixed integrated valve block 22 and the movable integrated valve block 21 are connected via a movable pipe body 23 .

[0039] When the positioner is changing position, the position of the fixed integrated valve block 22 always remains fixed, while the movable integrated valve block 21 moves with the movable frame assembly. The positioner in the utility model integrates the reversing control valve block of the action drive element used to realize the arm rotation action, lifting action, sliding action, and the opening and closing action of the trash bin 4 on the movable integrated valve block 21. The fixed integrated valve block only needs to lead out two movable pipe bodies to connect with the movable integrated valve block to realize the oil supply to the arm rotation cylinder, lifting cylinder, sliding cylinder, and door drive cylinder. Compared with the existing at least eight movable pipe bodies 23, the number of movable pipe bodies 23 is greatly reduced, making the pipeline layout of the positioner more concise. At the same time, the reduction in the number of movable pipe bodies 23 can reduce the risk of leakage at the hose connection and reduce the system failure rate.

[0040] It should be noted that in order to be compatible with the flipping action of the flip frame 12, the movable pipe body 23 needs to be configured in a relaxed state during layout, and the fixed pipe body is generally bound to the derrick platform 11 or the pipe rack of the movable frame assembly, and in terms of material, the fixed pipe body is generally a metal pipe, and the movable pipe body is generally a rubber hose.

[0041] In the embodiment of the present utility model, the movable tube body 23 may be a movable rubber hose.

[0042] like Figure 1 As shown, in the embodiment of the utility model, the movable frame assembly includes a turning frame 12 rotatably arranged on the derrick platform 11 and a sliding frame 13 slidably arranged on the turning frame 12, a sliding oil cylinder is arranged between the sliding frame 13 and the turning frame 12, and the movable integrated valve block 21 is arranged on the turning frame 12 or the sliding frame 13. The turning frame 12 is used to drive the garbage bin 4 to turn over, and the sliding frame 13 is used to drive the garbage bin 4 to linearly move relative to the turning frame 12. When the turning frame 12 turns over, the sliding frame 13 needs to turn over with the turning frame 12. The reversing control valve block of the sliding oil cylinder is integrated on the movable integrated valve block 21. By setting the movable integrated valve block 21 on the turning frame 12 or the sliding frame 13, a fixed pipe body connection between the sliding oil cylinder and the movable integrated valve block 21 can be realized, and the number of movable pipe bodies 23 between the movable integrated valve block 21 and each action driving element is effectively reduced.

[0043] Specifically, Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the movable integrated valve block 21 includes a first reversing valve link 211, and the two oil ports of the first reversing valve link 211 are respectively hydraulically connected to the two rod chambers of the sliding oil cylinder through the first fixed pipe body. The hydraulic interface of the sliding oil cylinder is generally arranged on the cylinder body of the oil cylinder. When the cylinder body of the sliding oil cylinder is connected to the flip frame 12, the movable integrated valve block 21 can be arranged on the flip frame 12 to ensure that the relative position between the hydraulic interface of the sliding oil cylinder and the movable integrated valve block 21 is fixed. Similarly, when the cylinder body of the sliding oil cylinder is connected to the sliding frame 13, the movable integrated valve block 21 is preferably arranged on the sliding frame 13.

[0044] like Figure 1 and Figure 4 As shown, in the embodiment of the utility model, the movable integrated valve block 21 is arranged on the flip frame 12 and is located between the hinged lugs on both sides of the flip frame 12. The derrick platform 11 is provided with a mounting platform 16 for hinged mounting of the flip frame 12. The fixed integrated valve block 22 is arranged on the mounting platform and is on the same side as the movable integrated valve block 21. The fixed integrated valve block 22 is also located between the hinged lugs on both sides of the flip frame 12. By arranging the fixed integrated valve block 22 on the mounting platform 16 and arranging it on the same side as the movable integrated valve block 21, the movable pipe body 23 only needs to be folded to cooperate with the flipping action of the flip frame 12, which not only reduces the movement amplitude of the movable pipe body 23, but also prevents the movable pipe body 23 from being pulled.

[0045] like Figure 1 and Figure 2As shown, the movable integrated valve block 21 is arranged on the flip frame 12, the movable frame assembly also includes a lifting frame 14 movably arranged on the sliding frame 13, and a lifting cylinder is also arranged between the lifting frame 14 and the sliding frame 13. The movable integrated valve block 21 includes a second reversing valve unit 212, and the two oil ports of the second reversing valve unit 212 are hydraulically connected to the two rod chambers of the lifting cylinder through the first movable tube body respectively, and the first movable tube body is arranged on the sliding frame along the sliding direction of the sliding frame 13.

[0046] Since the position of the lifting cylinder relative to the movable integrated valve block 21 will change when the sliding frame 13 is displaced, the lifting cylinder and the movable integrated valve block 21 need to be connected via a movable tube body. Since the sliding direction of the sliding frame is fixed, the first movable tube body can be arranged along the sliding direction of the sliding frame 13 to facilitate the fixation of the first movable tube body. By fixing the first movable tube body, it is possible to avoid the first movable tube body from being hung sharply, which may cause confusion in pipeline layout or interference in movement. At the same time, when the first movable tube body is fixed, it is necessary to reserve slack sections of sufficient length at both ends of the first movable tube body to be compatible with the movement of the sliding frame and the lifting frame.

[0047] Likewise, if Figure 1 , Figure 2 and Figure 4 As shown, the movable frame assembly also includes a swivel arm frame 15 arranged on the lifting frame 14, a swivel arm oil cylinder is arranged between the swivel arm frame 15 and the lifting frame 14, and the movable integrated valve block 21 includes a third reversing valve link 213, and two oil ports of the third reversing valve link 213 are respectively hydraulically connected to two rod chambers of the swivel arm oil cylinder through a second movable pipe body, and the second movable pipe body is arranged on the sliding frame along the sliding direction of the sliding frame 13. The arrangement of the second movable pipe body is similar to that of the first movable pipe body.

[0048] In an embodiment of the utility model, when arranging the electrical circuits, the electrical circuits and the hydraulic pipelines can be arranged side by side. The electrical circuits are movable only in the area parallel to the movable tube body, and the other areas are fixed. By arranging the electrical circuits and the hydraulic pipelines side by side, the number of movable electrical circuits can be reduced.

[0049] like Figure 2 As shown, in the embodiment of the utility model, the action driving element also includes a door driving cylinder for driving the garbage door of the garbage bin 4 to open and close, and the movable integrated valve block 21 includes a fourth reversing valve link 214, and the two oil ports of the fourth reversing valve link 214 are respectively hydraulically connected to the two rod chambers of the door driving cylinder through the second fixed pipe body. The door driving cylinder can be set on the flip frame 12, and the movable integrated valve block 21 and the door driving cylinder can be connected through the fixed pipe body.

[0050] In the embodiment of the utility model, the movable integrated valve block 21 is also provided with a spare interface 215 for installing a spare reversing valve. By providing the spare interface 215, it is possible to optimize the equipment and increase the action as a reserve, and by using an integrated valve block, the versatility of the parts can be increased.

[0051] In the embodiment of the utility model, the reversing valve for controlling the reversing of the tilting cylinder 121 may be arranged on the fixed integrated valve block 22 .

[0052] In the embodiment of the present utility model, the fixed integrated valve block 22 is preferably arranged close to the movable integrated valve block 21 to reduce the length of the movable pipe body 23 and increase the overall simplicity of the device.

[0053] To achieve the above purpose, the utility model also provides a garbage compression station, wherein the garbage compression station includes the positioner and the pump station 3 described above, and the pump station 3 is hydraulically connected to the fixed integrated valve block 22 in the positioner. The pump station 3 is provided with a motor and a pump group, and the pump group is mainly used to output hydraulic oil to the fixed integrated valve block 22. Since the garbage compression station in the utility model adopts all the technical solutions of the above embodiments, it has at least the beneficial effects brought by the above embodiments, which will not be repeated here.

[0054] like Figure 3 As shown, in the embodiment of the utility model, the garbage compression station is provided with a plurality of garbage compression berths, the number of positioners is a plurality, and the plurality of positioners correspond to the plurality of garbage compression berths one by one. The pump station 3 also has a main reversing valve, and the main reversing valve is used to selectively supply the hydraulic oil output by the oil pump to one of the positioners. By setting up a plurality of positioners, the function of one pump station 3 dragging a plurality of positioners to work is realized, the number of hydraulic pipelines is reduced, and the layout of the hydraulic system of the positioner is more concise and the cost is lower.

[0055] In the embodiment of the utility model, the oil pump is driven by a servo motor. By adjusting the speed of the servo motor, the oil pressure output by the oil pump can be matched with the current action of the positioner, thereby reducing the energy consumption of the positioner during operation.

[0056] The positioner in the present invention will be described below in conjunction with the specific position shifting process of the garbage bin 4 .

[0057] like Figure 4As shown, after the garbage transfer vehicle transports the empty garbage bin 4 to the garbage compression berth and places it horizontally in place, the lifting frame 14 and the rotating arm frame 15 are first controlled to move, so that the rotating arm frame 15 hooks the hook on the outside of the garbage bin 4, and then the turning frame 12 is controlled to turn up at a small angle, so that the turning frame 12 in a lying state and the sliding frame 13 on the turning frame 12 are separated from the ground; when the sliding frame 13 is separated from the ground, the sliding frame 13 is driven to slide horizontally, which can drive the garbage bin 4 to move horizontally until the root of the garbage bin 4 moves to the side of the deep pit (at this time, the shape of the garbage bin 4 is Figure 4 When the garbage bin 4 is horizontally displaced to a certain position, the overturning frame 12 is controlled to turn down, so that the lying garbage bin 4 together with the overturning frame 12 and the sliding frame 13 on the overturning frame 12 can be displaced into the following Figure 4 The vertical form shown. When the trash bin 4 becomes vertical, it is necessary to control the sliding frame 13 and the lifting frame 14 to retract downward so that the entire trash bin 4 sinks into the deep pit. At this time, the displacement operation of the entire trash bin 4 has been completed. Among them, the downward flipping displacement operation of the trash bin 4 can be summarized as: the rotating arm opens → lifts and extends → the flip frame 12 flips up at a small angle → slides and pushes out horizontally → the flip frame 12 flips down → slides and retracts vertically → lifts and retracts. Similarly, the upward flipping displacement operation of the trash bin 4 can be divided into: lifts and extends → slides and pushes out vertically → the flip frame 12 flips up → slides and retracts horizontally → automatically drops the box → lifts and retracts → the rotating arm retracts.

[0058] In the embodiment of the utility model, after the trash bin 4 is sunk into place, the door of the trash bin 4 can be controlled to open by the door driving cylinder, or before the trash bin 4 is filled with trash and shifted, the door of the trash bin 4 can be controlled to close.
