Description

Technical Field

[0001] This utility model relates to an adjustable anti-settlement manhole cover. Background Technology

[0002] Urban construction involves numerous underground pipelines, such as sewers, underground gas pipelines, water supply pipelines, power pipelines, communication pipelines, and defense pipelines. These pipelines have an outlet to the surface at intervals; this section from the pipeline to the surface is called a manhole. The manhole opening is usually flush with the ground, thus requiring a cover, called a manhole cover. Traditional manhole covers directly transmit weight to the manhole body. Frequent pressure from the road or damage to the cement can easily cause the manhole cover to sink. The height difference between the manhole cover and the road surface causes vehicles to bump, potentially leading to tire blowouts, wheel rim damage, or even complete collapse, creating a "black hole" in the road, which could cause pedestrians or non-motorized vehicles to fall into the manhole and suffer injuries or fatalities, posing a safety hazard. Therefore, improvements and optimizations are needed to address this issue. Utility Model Content

[0003] To address the aforementioned problems, the technical issue this utility model aims to resolve is to provide an adjustable anti-settlement manhole cover.

[0004] The technical solution adopted by this utility model of adjustable anti-settlement manhole cover is characterized by comprising an upper manhole cover seat, a manhole cover plate, an anti-settlement lower seat, and an adjusting sleeve. The upper manhole cover seat includes an upper seat receiving part with an upper seat through hole. The upper manhole cover seat has a square structure. The upper seat receiving part has an inner circumference at the upper seat through hole. The inner wall of the inner circumference is provided with an inner stop for limiting the position when the manhole cover plate is installed. Upper seat connecting blocks are provided at the four corners of the upper seat receiving part. The anti-settlement lower seat includes a lower seat base plate with a connecting sleeve inside. The base plate has a through hole that communicates with the upper seat through hole. The lower seat base plate has lower seat support blocks at its four corners that correspond to the upper seat docking blocks. The lower seat support blocks have support block studs. The adjusting sleeve includes an adjusting sleeve guide, an adjusting sleeve support abutting the bottom of the upper seat receiving part, and an adjusting sleeve adjusting part for adjustment, arranged sequentially from top to bottom. The adjusting sleeve has an adjusting sleeve threaded hole that is threadedly connected to the support block studs. The bottom of the upper seat docking block has a docking block positioning hole for positioning the adjusting sleeve guide.

[0005] The lower support block is provided with a stud protective guard outside the stud of the support block, and the upper docking block is provided with a docking block limiting groove outside the docking block positioning hole for inserting the stud protective guard.

[0019] like Figure 1-7As shown, the adjustable anti-settlement manhole cover of this utility model includes an upper manhole cover seat 1, a manhole cover plate 2, an anti-settlement lower seat 3, and an adjusting sleeve 4. The upper manhole cover seat 1 includes an upper seat receiving part 7, and an upper seat through hole 8 is provided in the upper seat receiving part 7. The upper manhole cover seat 1 has a square structure. The upper seat receiving part 7 has an upper seat inner perimeter 9 at the upper seat through hole 8. The inner wall of the upper seat inner perimeter 9 has an upper seat inner stop 11 for limiting the position when the manhole cover plate 2 is closed. The upper seat receiving part 7 has upper seat connecting blocks 10 at its four corners. The anti-settlement lower seat 3 includes a lower seat base plate 13, and a base plate through hole 14 communicating with the upper seat through hole 8 is provided in the lower seat base plate 13. The lower seat base plate 13 has corresponding upper seat connecting blocks 10 at its four corners. The lower support block 15 is provided with a support block stud 16. The adjusting sleeve 4 includes an adjusting sleeve guide part 18, an adjusting sleeve support part 19 abutting the bottom of the upper support part 7, and an adjusting sleeve adjusting part 20 for adjustment, arranged sequentially from top to bottom. The adjusting sleeve 4 is provided with an adjusting sleeve threaded hole 22 that is threadedly connected to the support block stud 16. The bottom of the upper support docking block 10 is provided with a docking block positioning hole 23 for positioning the adjusting sleeve guide part 18. The anti-settlement lower seat 3 plays a role in reinforcing the bottom support. By adjusting the adjusting sleeve 4, the vertical height of the manhole cover upper seat 1 can be finely adjusted, which can compensate for the height difference caused by cement settlement or road subsidence, keep the manhole cover flush with the road surface, reduce the safety risks to vehicles and personnel, and is flexible in operation and highly safe.

[0020] The lower support block 15 is provided with a stud protective guard 25 outside the support block stud 16. The upper docking block 10 is provided with a docking block limiting groove 26 outside the docking block positioning hole 23 for inserting the stud protective guard 25. The inner side of the stud protective guard 25 is provided with a guard operation port 27 that communicates with the bottom plate through hole 14 and is used for personnel to operate the adjustment sleeve adjustment part 20. The anti-settlement lower seat 3 is buried deeper underground. The stud protective guard 25 effectively prevents cement from entering during installation and affecting the operation of the support block stud 16, making the adjustment sleeve 4 more stable and smooth when rotating. The operator uses tools to adjust the adjustment sleeve 4 through the guard operation port 27.

[0021] It also includes a pre-tightening spring 5. The adjusting sleeve 4 also includes an adjusting sleeve lower stop 21 located below the adjusting sleeve adjusting part 20. The pre-tightening spring 5 is sleeved on the support block stud 16, with its upper end abutting against the adjusting sleeve lower stop 21 and its lower end abutting against the lower seat support block 15. The pre-tightening spring 5 plays a role in providing auxiliary support for the adjusting sleeve 4, while also mitigating impact and improving the service life of the manhole cover.

[0022] The upper surface of the lower support block 15 is provided with a support block sinking groove 29 for positioning the lower end of the pre-tightening spring 5. When the upper seat of the manhole cover 1 sinks excessively, the pre-tightening spring 5 sinks into the support block sinking groove 29, and the lower support block 15 directly contacts the upper seat receiving part 7 to achieve hard contact. This effectively prevents the pre-tightening spring 5 from being damaged and further improves the ability of the upper seat of the manhole cover 1 to prevent settlement.

[0023] The adjusting sleeve adjusting part 20 has a regular hexagonal structure, which makes it more stable under force and more reliable in operation.

[0024] The manhole cover plate 2 is provided with a cover plate flipping part 30 at one end. The inner side of the upper seat inner circumference 9 forms an upper seat flipping opening 31 that connects with the cover plate flipping part 30. The manhole cover plate 2 can be swayed and connected to the upper seat flipping opening 31 through the cover plate flipping part 30. The manhole cover plate 2 is provided with a cover plate pry opening 32, which makes operation more convenient and quick and improves maintenance efficiency.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
