Description

Technical Field

[0001] The utility model relates to the technical field of push-pull devices, in particular to a hook claw type push-pull box device. Background Art

[0002] For a long time, the main equipment used by the sanitation department in garbage compression transfer stations is garbage compressors. Garbage compressors can be divided into two types in terms of compression methods: horizontal compression type and vertical compression type; and can be divided into two types in terms of structure: integral type and split type.

[0003] The split type horizontal garbage compressor consists of the main engine box of the compressor and a garbage compression container. The container moves towards the main engine box. When the two are at a certain distance, the push-pull mechanism hooks the vertical docking column on the container to achieve the docking of the two. After the garbage is full, the push-pull mechanism unlocks to achieve the separation of the two.

[0004] The existing push-pull box devices have the following disadvantages:

[0005] 1. To achieve the connection with the vertical docking column on the container, its connection end is usually exposed at one end of the main body of the compressor. When there is no need for docking work, the exposed push-pull box device is easily damaged by collision and there are certain safety hazards.

[0006] 2. During docking, the allowable docking distance range between the container and the main engine box is small. If they are too close, they will collide, and if they are too far apart, they cannot be successfully connected to the vertical docking column, making the operation difficult.

[0007] 3. The existing push-pull box devices usually have a complex structure and are difficult to disassemble and repair.

[0008] 4. The push-pull box device cannot achieve autonomous separation from the main engine box after the container is loaded. Even if the push-pull box returns, there is a situation where the push-pull box is pulled back together.

[0009] In view of the problems existing in the above-mentioned prior art, the utility model designs and manufactures a hook claw type push-pull box device to overcome the above defects. Summary of the Invention

[0010] Regarding the problems existing in the prior art, a hook claw type push-pull box device provided by the utility model can reduce the operation difficulty during the docking of the container, and reduce the maintenance cost and safety hazards.

[0011] To achieve the above purpose, the technical solution adopted by the utility model is as follows: A hook claw type push-pull box device includes a frame body, the frame body is installed at one end of the bottom of the main engine box close to the container, and the installation direction of the frame body is parallel to the movement direction of the container during docking;

[0012] A docking component capable of hooking the vertical connecting column is slidably installed on the frame body, and a first cylinder for driving the docking component to slide is installed on the frame body;

[0013] The docking component includes a connecting seat installed on the telescopic end of the first cylinder. A hook claw is hinged on the connecting seat, and a second cylinder for driving the hook claw to rotate is installed on the connecting seat.

[0015] The hook claw is an L-shaped block. A connecting block is provided on one side of the long side of the L-shaped block close to the connecting seat. An installation groove is provided on the connecting seat, and the connecting block is hinged in the installation groove;

[0016] When the long side of the L-shaped block rotates to a state parallel to the side of the connecting seat, the short side of the L-shaped block is parallel to the push plate, and the vertical docking column is clamped between the push plate and the L-shaped block;

[0017] One end of the second cylinder is rotatably installed on the side of the connecting seat close to the L-shaped block, and the other end of the second cylinder is rotatably connected to the L-shaped block.

[0018] Preferably, a non-slip layer is provided on the surface of the push plate in contact with the vertical docking column.

[0019] Preferably, a distance sensor for detecting the distance between the vertical connecting column and the push plate is provided on the push plate.

[0035] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the drawings.

[0036] As Figures 1-3 shown, a hook-type push-pull box device includes a frame body 11. The frame body 11 is installed at one end of the bottom of the main chassis close to the container. The installation direction of the frame body 11 is parallel to the movement direction of the container during docking. A docking assembly 12 capable of hooking the vertical connection column is slidably installed on the frame body 11, and a first cylinder 5 for driving the docking assembly 12 to slide is installed on the frame body 11;

[0037] The first cylinder 5 of the utility model drives the docking assembly 12 to reciprocate on the frame 11. During docking, the distance at which the container docks does not need to be very precise. The first cylinder 5 can drive the docking assembly 12 to extend from the bottom of the main chassis and actively approach the vertical docking column on the container, achieving active docking with the container and making the operation more convenient.

[0038] In addition, when no docking operation is required, the docking assembly 12 can also slide along the frame 11 under the drive of the first cylinder 5 and retract under the main chassis, avoiding damage to the protruding end from being collided, and also preventing tripping the operator, reducing potential safety hazards.

[0039] Specifically, the docking assembly 12 includes a connecting seat 1. The connecting seat 1 is installed on the telescopic end of the first cylinder 5. A hook claw is hinged on the connecting seat 1. A second cylinder 2 for driving the hook claw to rotate is installed on the connecting seat 1. The rotating hook claw can hook and lock the vertical docking column. After loading is completed, the second cylinder 2 controls the hook claw to rotate in the reverse direction to achieve unhooking.

[0040] One end of the connecting seat 1 of the utility model is detachably connected to the first cylinder 5. A push plate 9 is installed at the other end of the connecting seat 1. The hook claw is an L-shaped block 10. A connecting block is provided on the side of the long side of the L-shaped block 10 close to the connecting seat 1. An installation groove is provided on the connecting seat 1. The connecting block is hinged in the installation groove. One end of the second cylinder 2 is rotatably installed on the side of the connecting seat 1 close to the L-shaped block 10, and the other end of the second cylinder 2 is rotatably connected to the L-shaped block 10.

[0041] Specifically, when the long side of the L-shaped block 10 rotates to a state parallel to the side of the connecting seat 1, the short side of the L-shaped block 10 is parallel to the push plate 9. The surface of the push plate 9 in contact with the vertical docking column is provided with an anti-slip layer. A distance sensor for detecting the distance between the vertical connecting column and the push plate 9 is provided on the push plate 9.

[0042] Specifically, during docking, the vertical docking column is clamped between the push plate 9 and the L-shaped block 10 to achieve locking. After the container loading is completed, the second cylinder 2 controls the L-shaped block 10 to rotate to release the locking of the vertical docking column. At the same time, the first cylinder 5 extends, and under the push of the push plate 9, the container is pushed away from the main chassis. After being pushed to a certain distance, the first cylinder 5 contracts to move the docking assembly 12 away from the container. After the distance sensor on the push plate 9 detects that it is far from the vertical docking column, the second cylinder 2 extends to control the L-shaped block 10 to reverse and reset. The second cylinder 2 continues to contract until the docking assembly 12 is retracted under the main chassis, which can effectively avoid the situation that the container is pulled back during the unhooking process, and the push plate 9 can also play a role in assisting separation;

[0043] An installation base 8 is installed between the first cylinder 5 of the utility model and the connecting seat. A hinge seat 3 is fixed on the installation base 8. One end of the second cylinder 2 away from the L-shaped block 10 is rotatably connected to the hinge seat 3. The frame body 11 includes an adjustment frame 6. The upper end of the adjustment frame 6 is installed at the bottom of the main chassis. At least two slide rail frames 4 are installed at the lower end of the adjustment frame 6. The first cylinder 5 is detachably installed at the lower end of the slide rail frame 4. The docking assembly 12 is slidably installed on the slide rail frame 4;

[0044] Specifically, the adjustment frame 6 is detachably installed at the bottom of the chassis through adjusting bolts, and the installation position and installation height of the entire push-pull device can be adjusted at any time, and it is also convenient for disassembly and maintenance. The docking assembly 12 is slidably installed on the slide rail frame 4, and the first cylinder 5 is detachably connected to the slide rail frame 4. During maintenance, components such as the first cylinder 5 and the docking assembly 12 that are more likely to be damaged can be separately disassembled and replaced from the adjustment frame 6, reducing the maintenance difficulty and maintenance cost.

[0045] The lower end of the installation base 8 of the utility model is jointly connected to the first cylinder 5 and the connecting seat. A slide bar 7 is connected to the upper end of the installation base 8. The slide bar 7 is slidably matched with the slide rail frame 4. The cross-section of the slide bar 7 is polygonal, which can prevent the slide bar 7 from rotating during the relative sliding with the slide rail frame 4 and affecting the docking of the hook claw and the vertical docking column.
