Description

Technical Field

[0001] This utility model relates to the field of municipal maintenance technology, and in particular to a manhole cover maintenance device for municipal use. Background Technology

[0002] Manholes are wells used at bends, branches, and drops in drainage pipes to facilitate inspection and dredging. They are technically called inspection wells. Since manhole covers are usually installed on the ground, and passing vehicles will exert a certain pressure on the manhole covers, they need to be maintained after long-term use to ensure their firmness and safety.

[0003] While manhole covers can usually be lifted up, they require manual support for maintenance. This process of supporting and maintaining the manhole cover is quite inconvenient.

[0004] Therefore, we propose a manhole cover maintenance device for municipal applications. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A manhole cover maintenance device for municipal use, such as Figure 1 - Figure 5 As shown, the device includes an installation ring 1, on which a manhole cover 2 is rotatably mounted. An inner clamping assembly is provided on the manhole cover 2, which abuts against its inner wall from the inside. Adjustment components are provided on both sides of the manhole cover 2. After the inner clamping assembly clamps the manhole cover 2, the adjustment components can be used to adjust the angle of the manhole cover 2 for easy maintenance by workers. By providing the inner clamping assembly and the adjustment components, when maintenance of the manhole cover 2 is required, the manhole cover 2 is rotated to an appropriate angle, clamped by the inner clamping assembly, and the angle of the inner clamping assembly is adjusted by the adjustment components to rotate the manhole cover 2 to a fixed angle and provide support, facilitating subsequent maintenance by workers.

[0026] Furthermore, the inner clamping assembly includes a positioning plate 12, which is movably mounted on the manhole cover 2. A movable seat 13 is rotatably mounted on the positioning plate 12, and drive arms 4 are movably mounted on the four sides of the movable seat 13. The drive arms 4 are rotatably connected to the movable seat 13, and inner clamping plates 5 are movably mounted on the four sides of the movable seat 13. When the four drive arms 4 extend to the four sides, the inner clamping plates 5 can abut against the inner wall of the manhole cover 2. The drive arms 4 are rotatably connected to the inner clamping plates 5. Two hydraulic telescopic rods are provided between the two inner clamping plates 5 in the transverse direction. The hydraulic telescopic rods are fixedly mounted on one side of the inner clamping plate 5, and the telescopic ends of the hydraulic telescopic rods are fixedly connected to the inner clamping plates 5 on the other side. By providing the inner clamping assembly, when the manhole cover 2 needs to be maintained, the two inner clamping plates 5 in the transverse direction are driven away from each other by controlling the hydraulic telescopic rods. The four inner clamping plates 5 are moved to the four sides and abut against the inner wall of the manhole cover 2 by the cooperation of the movable seat 13 and the drive arms 4 to clamp the manhole cover 2.

[0027] Furthermore, the adjustment assembly includes two first telescopic rods 6, which are arranged on both sides of the mounting plate 3. The telescopic ends of the first telescopic rods 6 are fixedly connected to the mounting plate 3. Extension plates 7 are movably installed on both sides of the mounting plate 3, and the extension plates 7 are fixedly connected to the first telescopic rods 6. A second telescopic rod 8 is fixedly installed on the extension plates 7. A moving block 10 is movably installed on the lower side of the extension plates 7, and the moving block 10 is rotatably connected to the telescopic end of the second telescopic rod 8. Placement frames 9 are provided on both sides of the mounting ring 1. When maintaining the manhole cover, the placement frame 9 is placed on the ground, and the moving block 10 is movably connected to the placement frame 9. A positioning assembly is provided on the placement frame 9, which can limit the movement of the moving block 10 to ensure the stability of the second telescopic rod 8. The adjustment assembly is included. When maintenance of the manhole cover 2 is required, lift the manhole cover 2, then place the positioning plate 12 in the center of the side of the manhole cover 2 near the mounting ring 1, pull the two first telescopic rods 6 on both sides, place the two placement brackets 9 on the ground on both sides of the mounting ring 1, then pull the second telescopic rod 8 upward. When the second telescopic rod 8 is pulled to the center of the manhole cover 2, place the positioning plate 12 against the inner wall of the manhole cover 2, control the hydraulic telescopic rod to drive the two inner clamping plates 5 in the lateral direction to move away from each other, and through the cooperation of the movable seat 13 and the drive arm 4, drive the four inner clamping plates 5 to move to the four sides and abut against the inner wall of the manhole cover 2 to clamp the manhole cover 2. Finally, slide the moving block 10 to drive the second telescopic rod 8 to move, so as to adjust the angle of the manhole cover 2.

[0028] Furthermore, the positioning component includes a rack 11, which is fixedly mounted on the placement frame 9. A connecting sleeve 16 is fixedly mounted on the movable block 10. An adjusting shaft 15 is movably mounted on the movable block 10 and is threadedly connected to the connecting sleeve 16. A locking tooth 14 is movably mounted on the movable block 10 and is rotatably connected to the adjusting shaft 15. The locking tooth 14 meshes with the rack 11. By providing the positioning component, when the second telescopic rod 8 is rotated and the movable block 10 is moved into position, the adjusting shaft 15 is rotated. The adjusting shaft 15 is threadedly connected to the connecting sleeve 16 and drives the locking tooth 14 to move downward until it meshes with the rack 11 to limit the movement of the movable block 10, thereby ensuring the stability of the well cover 2 when supported.

[0029] The working principle of this utility model is as follows: When maintenance of the manhole cover 2 is required, the manhole cover 2 is lifted, and then the positioning plate 12 is placed at the center of the side of the manhole cover 2 near the mounting ring 1. The two first telescopic rods 6 on both sides are pulled to place the two placement brackets 9 on both sides of the mounting ring 1 on the ground. Then, the second telescopic rod 8 is pulled upward. When the second telescopic rod 8 is pulled to the center position of the positioning plate 12, the positioning plate 12 is attached to the inner wall of the manhole cover 2. The hydraulic telescopic rod is controlled to drive the two inner clamping plates 5 in the lateral direction to move towards each other. The manhole cover 2 is moved away from the wall and the four inner clamping plates 5 move to the four sides and abut against the inner wall of the manhole cover 2 through the cooperation of the movable seat 13 and the drive arm 4 to clamp the manhole cover 2. Finally, the sliding moving block 10 drives the second telescopic rod 8 to move to adjust the angle of the manhole cover 2. When the manhole cover 2 is adjusted to the position, the adjusting shaft 15 is rotated. The adjusting shaft 15 drives the locking tooth 14 to move downward to mesh with the rack 11 to fix the position of the moving block 10. At this time, the manhole cover 2 is supported at a fixed angle, and the subsequent staff can maintain the manhole cover 2.
