Description

Technical Field

[0001] This application relates to the field of well lifting device technology, specifically a well joint lifting device with an automatic lifting manipulator for well covers. Background Technology

[0002] The apron is the core area for transportation operations at a civil airport. This area is used for aircraft parking, passenger pick-up and drop-off, cargo loading and unloading, and various ground services. The apron has numerous manholes, and manhole covers protect these manholes while allowing for easy access for maintenance and refueling operations. Manhole connection lifting devices can extract wastewater from the manholes via pipelines, preventing wastewater from affecting construction work inside the manholes.

[0003] During the construction of the well, workers need to lift the well cover. However, the well cover is quite heavy and inconvenient to lift, which makes it difficult for the well joint lifting device to carry out construction inside the well, thus affecting the use of the well joint lifting device.

[0004] Therefore, there is an urgent need for a manhole cover lifting device with an automatic lifting robot to solve the problem of inconvenient construction of manhole cover lifting devices. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a manhole cover lifting device with an automatic lifting robot, which has the advantage of easily lifting the manhole cover and solves the problem of inconvenient construction of manhole cover lifting devices.

[0006] To achieve the above objectives, this application provides the following technical solution: a manhole cover lifting device with an automatic lifting manipulator, comprising a manhole cover lifting device body, a first support arm, a second support arm, a first cylinder, a connecting plate, a gripper, a first connecting block, a second cylinder, a support cylinder, a drive motor, a threaded rod, and a threaded sleeve. The first support arm is rotatably connected to the top of the manhole cover lifting device body frame. The second support arm and the first support arm are connected by an adjustment assembly. The first cylinder is installed inside the second support arm. The connecting plate is fixedly connected to the output end of the first cylinder by screws. The first connecting block is rotatably connected to both ends of the connecting plate by a shaft. The second cylinder is rotatably connected to the inner side of the first connecting block by a shaft. Both ends of the second cylinder are fixedly connected to the inner side of the first connecting block by bolts. A cylinder controller is installed on the second support arm.

[0007] The adjustment assembly includes a support cylinder, a drive motor, a threaded rod, and a threaded sleeve. The support cylinder is welded to one end of the support arm. The drive motor is installed inside the support cylinder. One end of the threaded rod is fixedly connected to the output end of the drive motor. The other end of the threaded rod is threadedly connected to one end of the threaded sleeve. The other end of the threaded sleeve is fixedly connected to one end of the support arm by bolts.

[0008] By changing the position and angle of the second support arm, and simultaneously illuminating the area below the connecting plate with the laser emitted by the laser device, the connecting plate can be more accurately aligned with the center of the manhole cover. This allows the grippers to clamp into the slots on both sides of the manhole cover. When the second cylinder drives the first connecting block to rotate inward, the manhole cover can be clamped, allowing the automatic lifting manhole cover lifting robot to easily clamp and lift the manhole cover. This also facilitates the extraction of sewage from the manhole by the manhole joint lifting device.

[0009] Preferably, support blocks are welded to both sides of the first support arm and the second support arm, and guide sleeves and guide rods are fixedly connected between the support blocks by bolts, with the guide sleeves and guide rods being slidably connected.

[0010] Preferably, a fixing plate is welded to the inner side of the support arm, and a connecting block 2 is rotatably connected to the inner side of the fixing plate via a shaft, and a laser device is provided on the outer side of the connecting block 2.

[0011] Preferably, a connecting plate is welded to one end of the shaft connecting the fixing plate and the connecting block two, and a fixing bolt is threaded to the outside of the connecting plate.

[0012] Preferably, the outer side of the fixing plate has several sets of insertion holes adapted to the fixing bolts, and the fixing bolts extend through the connecting plate into the insertion holes.

[0013] In summary, the beneficial effects of this application are:

[0014] This manhole cover automatic lifting robot's manhole connector lifting device, when the manhole connector lifting device moves, the laser emitted by the laser instrument can illuminate the area below the connecting plate, thereby determining the position of the connecting plate. The operator can push the second support arm, which drives the first support arm to rotate on top of the manhole connector lifting device body, thereby changing the angle of the gripper below the connecting plate. At the same time, when the threaded rod rotates, it drives the second support arm to move through the threaded sleeve. The second support arm drives the connecting plate and gripper below to move to the appropriate position, so that the connecting plate can be more accurately aligned with the center of the manhole cover, making it easier for the gripper to clamp into the slots on both sides of the manhole cover. When the second cylinder drives the first connecting block to rotate inward, it can clamp the manhole cover, allowing the automatic manhole cover lifting robot to easily clamp and lift the manhole cover, facilitating the manhole connector lifting device to pump out sewage from the well.

The first support arm 2 is rotatably connected to the top of the frame of the manhole cover lifting device body 1. The second support arm 3 and the first support arm 2 are connected by an adjustment assembly. The first cylinder 4 is installed inside the second support arm 3. The connecting plate 5 is fixedly connected to the output end of the first cylinder 4 by screws. The first connecting block 7 is rotatably connected to both ends of the connecting plate 5 by a shaft. The second cylinder 8 is rotatably connected to the inside of the first connecting block 7 by a shaft. The two ends of the second cylinder 8 are fixedly connected to the inside of the first connecting block 7 by bolts. A cylinder controller 22 is installed on the second support arm 3.

[0022] Through the above technical solution, the staff can push the manhole connector lifting device body 1. The universal wheels at the bottom of the manhole connector lifting device body 1 can drive the manhole connector lifting device body 1 to move. The pipe inside the manhole connector lifting device body 1 can pump out the sewage inside the manhole through the water pump. After the manhole connector lifting device body 1 moves to a suitable position, the staff can start cylinder 4 through cylinder controller 22. Cylinder 4 drives the connecting plate 5 to move up and down. The connecting plate 5 drives the gripper 6 to move above the manhole cover. Cylinder 4 drives the gripper 6 to move down through the connecting plate 5 and clamp it into the slots on both sides of the manhole cover. Cylinder controller 22 starts cylinder 8. When cylinder 8 drives the gripper 6 to rotate inward through connecting block 7, the gripper 6 can clamp the manhole cover. Cylinder 4 drives the manhole cover to move up through the connecting plate 5 and the gripper 6, so that the manhole cover can be easily lifted.

[0023] Specifically, the adjustment assembly includes a support cylinder 9, a drive motor 10, a threaded rod 11, and a threaded sleeve 12. The support cylinder 9 is welded to one end of the support arm 2. The drive motor 10 is installed inside the support cylinder 9. One end of the threaded rod 11 is fixedly connected to the output end of the drive motor 10. The other end of the threaded rod 11 is threadedly connected to one end of the threaded sleeve 12. The other end of the threaded sleeve 12 is fixedly connected to one end of the support arm 3 by bolts.

[0024] Support blocks 13 are welded to both sides of support arm 12 and support arm 23. Guide sleeves 14 and guide rods 15 are fixedly connected between the support blocks 13 by bolts. Guide sleeves 14 and guide rods 15 are slidably connected.

[0025] Through the above technical solution, the support block 13 can support the guide sleeve 14 and the guide rod 15. The guide rod 15 slides inside the guide sleeve 14, thereby guiding the movement of the support arm 3.

[0026] Specifically, a fixing plate 16 is welded to the inner side of the support arm 12. A connecting block 2 17 is rotatably connected to the inner side of the fixing plate 16 via a shaft. A laser device 18 is provided on the outer side of the connecting block 2 17. A connecting plate 19 is welded to one end of the shaft connecting the fixing plate 16 and the connecting block 2 17. A fixing bolt 20 is threaded to the outer side of the connecting plate 19. Several sets of insertion holes 21 adapted to the fixing bolts 20 are opened on the outer side of the fixing plate 16. The fixing bolts 20 pass through the connecting plate 19 and extend into the insertion holes 21.

[0027] With the above technical solution, the staff can push the connecting block 2 17, which drives the laser device 18 to rotate. The connecting block 2 17 drives the connecting piece 19 and the fixing bolt 20 to rotate through the shaft. When the laser device 18 rotates to the appropriate position, the staff rotates the fixing bolt 20, which is inserted into the socket 21 to fix the position of the laser device 18.

[0028] When the manhole cover lifting device moves, the laser emitted by the laser instrument 18 can illuminate the area below the connecting plate 5, thereby determining the position of the connecting plate 5. The operator can push the second support arm 3, which drives the first support arm 2 to rotate on the top of the manhole cover lifting device body 1, thereby changing the angle of the gripper 6 below the connecting plate 5. The drive motor 10 is then started, which drives the threaded rod 11 to rotate. When the threaded rod 11 rotates, it drives the second support arm 3 to move through the threaded sleeve 12. The second support arm 3 drives the connecting plate 5 and the gripper 6 below to move to the appropriate position, so that the connecting plate 5 can be more accurately aligned with the middle position of the manhole cover, making it easier for the gripper 6 to clamp into the slots on both sides of the manhole cover. When the second cylinder 8 drives the first connecting block 7 to rotate inward, it can clamp the manhole cover, allowing the automatic lifting manhole cover lifting robot to easily clamp and lift the manhole cover, making it easier for the manhole cover lifting device to extract sewage from the well.
