Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, and in particular to an adjustable settlement deformation manhole cover. Background Technology

[0002] Manhole covers are movable sealing devices located at the openings of various inspection wells, drainage wells, cable wells, etc., and are usually made of cast iron, steel, concrete, or other sturdy materials. Their main function is to cover the manhole opening, prevent foreign objects from falling in, ensure the safe operation of the facilities underground, and provide a safe road surface for pedestrians and vehicles. Manhole covers are usually designed with specific patterns and holes to facilitate identification of the type of facility underneath and to facilitate opening and maintenance. In addition, manhole covers should have a certain load-bearing capacity to withstand the weight from road traffic.

[0003] In current urban infrastructure, manhole covers are generally installed using fixing bolts and other connection structures to tightly secure them to the manhole body. Under normal circumstances, this installation method can ensure the stability of the manhole cover and the safety of the road. However, as the ground ages, ground subsidence inevitably occurs. In this case, the fixed manhole cover cannot automatically adjust with the ground subsidence, causing the edge of the manhole cover to rise above the ground, forming an uneven road surface. This situation not only affects the comfort and safety of driving, but may also cause vehicle damage and pedestrian falls, thus adversely affecting urban traffic and residents' lives. Utility Model Content

[0004] One objective of this invention is to provide an adjustable settlement deformation manhole cover. This invention addresses the problem mentioned in the background that, with the increase in the years of ground use, ground settlement inevitably occurs. In this situation, the fixed manhole cover cannot automatically adjust with the ground settlement, resulting in the edge of the manhole cover being higher than the ground, forming an uneven road surface. This situation not only affects the comfort and safety of driving, but may also cause vehicle damage and pedestrian falls, thus adversely affecting urban traffic and residents' lives.

[0005] An adjustable settlement deformation manhole cover according to an embodiment of the present invention includes an overlapping structure for erecting the manhole cover body installed inside the manhole cover frame, a rotating shaft structure for adjusting the lifting and lowering of the manhole cover structure within the manhole cover frame, and a positioning structure for locking the manhole cover body after it is closed. The manhole cover structure includes the manhole cover body. The overlapping structure includes a first lifting block and a step. The first lifting block is movably connected to the inside of the manhole cover frame, and the step is fixedly connected to one side of the first lifting block. The rotating shaft structure includes a second lifting block and a rotating shaft. The second lifting block is movably connected to the inner surface of the manhole cover frame. Two sets of the second lifting blocks are provided. The rotating shaft is fixedly connected to the inner side of the two sets of second lifting blocks. The manhole cover body is rotatably connected to the inside of the manhole cover frame via the rotating shaft. The positioning structure includes a positioning rod and a positioning nut. The positioning rod passes through the manhole cover body and the manhole cover frame, and the positioning nut is threaded onto the surface of the positioning rod.

[0006] Preferably, a first lifting groove is provided on the inner side of the manhole cover frame, and a first screw is rotatably connected inside the lifting groove. A first cross hole is provided on the upper surface of the first screw, and the first lifting block is threadedly connected to the surface of the first screw.

[0007] Preferably, the inner surface of the manhole cover frame is provided with a second lifting groove, the interior of the second lifting groove is rotatably connected to a second screw, the upper surface of the second screw is provided with a second cross hole, and the second lifting block is threadedly connected to the surface of the second screw.

[0008] Preferably, the second lifting block and the second screw are each provided in two sets, and the two sets of the second screw and the second lifting block are connected to each other through a transmission structure, the transmission structure including a first gear and a second gear.

[0009] Preferably, the first gear is fixedly connected to the lower end of a set of second screws, the second gear is fixedly connected to the lower end of another set of second screws, and the first gear and the second gear are connected to each other by a transmission belt.

[0010] Preferably, both sides of the manhole cover frame are provided with positioning grooves to facilitate the adjustment of the position of the positioning rod and the positioning nut.

[0011] Preferably, the surface of the manhole cover body has several drainage outlets.

[0012] Preferably, the upper surface of the manhole cover body is fixedly connected with anti-slip protrusions, and the upper surface of the manhole cover body is provided with a groove to facilitate manual lifting of the manhole cover body.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through its overlapping and rotating shaft structures, allows the manhole cover to be rotatably installed inside the manhole cover frame. When ground subsidence occurs after prolonged use, causing the manhole cover to rise above the surrounding ground, a Phillips screwdriver or electric drill is used to rotate the first screw through the first Phillips hole. This causes the first lifting block to slide downwards within the first lifting groove, thereby lowering the steps of the overlapping structure. Simultaneously, the second screw is rotated through the second Phillips hole, causing the second lifting block and the rotating shaft to slide downwards, thus lowering the entire manhole cover until it is below the surrounding ground level. This achieves the function of automatically adjusting the height of the manhole cover as the ground subsides, effectively avoiding safety hazards caused by the manhole cover protruding from the ground and improving road smoothness and the safety of pedestrians and vehicles.

[0015] This utility model features a transmission structure with two sets of second screws and second lifting blocks. When the first set of second screws is rotated, it drives the first gear of the transmission structure to rotate. The first gear drives the second gear to rotate synchronously via a transmission belt, thereby causing the second set of second screws to rotate synchronously. This ensures that the two sets of second lifting blocks on both sides of the rotating shaft move up and down synchronously, keeping the rotating shaft in a horizontal state at all times. This improves the stability and uniformity of the manhole cover adjustment process and avoids the imbalance and potential safety risks caused by tilting the manhole cover.

[0016] This utility model, through its positioning structure, allows the positioning nut to be removed from the surface of the positioning rod before the manhole cover body is lifted through the groove. The positioning rod is then removed from the positioning groove, allowing the manhole cover body to be lifted from the surface of the manhole cover frame. After the manhole cover body is placed on the step, the positioning rod is inserted through the hole and positioning groove in the manhole cover body, and the positioning nut is threaded onto the end of the positioning rod, thus locking the position of the manhole cover body. This makes the disassembly and installation of the manhole cover body more convenient and safer, while ensuring the precise locking of the manhole cover after repositioning, improving the overall stability of the manhole cover and road safety.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-4An adjustable settlement deformation manhole cover includes an overlapping structure 3 installed inside a manhole cover frame 1 for mounting the manhole cover body 201, a rotating shaft structure 4 for adjusting the lifting and lowering of the manhole cover structure 2 within the manhole cover frame 1, and a positioning structure 6 for locking the manhole cover body 201 after it is placed on. The manhole cover structure 2 includes the manhole cover body 201. The overlapping structure 3 includes a first lifting block 303 and a step 304. The first lifting block 303 is movably connected to the inside of the manhole cover frame 1, and the step 304 is fixedly connected to one side of the first lifting block 303. The rotating shaft structure 4 includes a second lifting block 403 and a rotating shaft 404. The second lifting block 403 is movably connected to the inner surface of the manhole cover frame 1. Two sets of second lifting blocks 403 are provided. The rotating shaft 404 is fixedly connected to the inner sides of the two sets of second lifting blocks 403. The manhole cover body 201 is rotatably connected to the inside of the manhole cover frame 1 via the rotating shaft 404. The positioning structure 6 includes a positioning rod 602 and a positioning nut 603. Positioning rod 602 passes through the manhole cover body 201 and the manhole cover frame 1. Positioning nut 603 is threaded onto the surface of positioning rod 602. The manhole cover is rotated and installed inside the manhole cover frame 1 via rotating shaft 404. When the ground settles after a long period of use, causing the manhole cover body 201 to be higher than the surrounding ground, a Phillips screwdriver or electric drill is used to rotate the first screw 302 through the first Phillips hole 305, causing the first lifting block 303 to slide downward inside the first lifting groove 301. This causes the step 304 of the overlapping structure 3 to slide downward. At the same time, the second screw 402 is rotated through the second Phillips hole 405, causing the second lifting block 403 and rotating shaft 404 to slide downward, thereby driving the entire manhole cover body 201 to descend until the manhole cover body 201 is lower than the surrounding ground. This realizes the function of automatically adjusting the height of the manhole cover as the ground settles, effectively avoiding the safety hazards caused by the manhole cover protruding from the ground, and improving the smoothness of the road and the safety of pedestrians and vehicles.

[0025] Example 1: A first lifting groove 301 is provided on the inner side of the manhole cover frame 1. A first screw 302 is rotatably connected inside the lifting groove. A first cross hole 305 is provided on the upper surface of the first screw 302. A first lifting block 303 is threadedly connected to the surface of the first screw 302. A second lifting groove 401 is provided on the inner surface of the manhole cover frame 1. A second screw 402 is rotatably connected inside the second lifting groove 401. A second cross hole 405 is provided on the upper surface of the second screw 402. A second lifting block 403 is threadedly connected to the surface of the second screw 402. Two sets of the second lifting block 403 and the second screw 402 are provided. The two sets of the second screw 402 and the second lifting block 403 are connected to each other through a transmission structure 5. The transmission structure 5 includes a first gear 501 and a second gear 502. The first gear 501 is fixedly connected to... A second gear 502 is fixedly connected to the lower end of another set of second screws 402. The first gear 501 and the second gear 502 are connected to each other by a transmission belt 503. Through the transmission structure 5, there are two sets of second screws 402 and second lifting blocks 403. When the first set of second screws 402 is rotated, the first gear 501 of the transmission structure 5 is driven to rotate. The first gear 501 drives the second gear 502 to rotate synchronously through the transmission belt 503, thereby making the second set of second screws 402 rotate synchronously. This ensures that the two sets of second lifting blocks 403 on both sides of the rotating shaft 404 rise and fall synchronously, so that the rotating shaft 404 is always in a horizontal state. This improves the stability and uniformity of the manhole cover adjustment process and avoids the imbalance and potential safety risks caused by the tilting of the manhole cover.

[0026] Example 2: Positioning grooves 601 are provided on both sides of the manhole cover frame 1 to facilitate the adjustment of the positions of the positioning rod 602 and the positioning nut 603. Using the positioning structure 6, before lifting the manhole cover body 201 through the groove 203, the positioning nut 603 is removed from the surface of the positioning rod 602, and the positioning rod 602 is taken out of the positioning groove 601. The manhole cover body 201 can then be lifted from the surface of the manhole cover frame 1 through the groove 203. After the manhole cover body 201 is placed on the step 304, the positioning rod 602 is inserted through the hole in the manhole cover body 201 and... Inside the positioning groove 601, the positioning nut 603 is threaded onto the end of the positioning rod 602 to lock the position of the manhole cover body 201, making the disassembly and installation of the manhole cover body 201 more convenient and safer. At the same time, it ensures that the manhole cover is accurately locked after being reset, improving the overall stability of the manhole cover and the safety of the road. Several drainage outlets 7 are opened through the surface of the manhole cover body 201. Anti-slip protrusions 202 are fixedly connected to the upper surface of the manhole cover body 201. The upper surface of the manhole cover body 201 has grooves 203 that facilitate manual lifting of the manhole cover body 201.

[0027] In use, the manhole cover is installed inside the manhole cover frame 1 via a rotating shaft 404. The step 304 of the overlapping structure 3 and the first lifting block 303 are movably connected inside the manhole cover frame 1. The second lifting block 403 of the rotating shaft structure 4 and the rotating shaft 404 are also movably connected to the inner surface of the manhole cover frame 1. Synchronous lifting is achieved through two sets of second lifting blocks 403 and the first gear 501 and second gear 502 of the transmission structure 5. When ground subsidence causes the manhole cover body 201 to be higher than the surrounding ground, the operator uses a Phillips screwdriver or electric drill to rotate the first screw 302 and the second screw 402 through the first Phillips hole 305 and the second Phillips hole 405 respectively, causing the first lifting block 303, the step 304, the second lifting block 403, and... The rotating shaft 404 slides downwards together, causing the manhole cover body 201 to descend as a whole until it is lower than the surrounding ground, thus achieving automatic height adjustment. During use, if the manhole cover body 201 needs to be disassembled, first remove the positioning nut 603, take out the positioning rod 602, and then manually lift the manhole cover body 201 through the groove 203. During installation, the manhole cover body 201 is placed on the step 304, the positioning rod 602 is reinserted, and the positioning nut 603 is threadedly connected to ensure the precise locking of the manhole cover body 201, which improves the overall stability of the manhole cover and the safety of the road. In addition, the design of the drain outlet 7 and the anti-slip protrusion 202 of the manhole cover body 201 further enhances its practicality and safety.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
