Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, specifically to an adjustable anti-settlement manhole cover for municipal engineering. Background Technology

[0002] Municipal engineering refers to the general term for various public infrastructure projects necessary for cities or towns to provide public services and ensure the normal operation and development of cities. In municipal engineering, the manhole cover is a key component of the manhole structure. It is not only the foundation for supporting and locking the manhole cover, but also the core link to ensure structural stability, traffic safety and the service life of the facility.

[0003] Manhole covers are usually installed on roads, and vehicles passing by frequently run over them. Over time, this can cause uneven stress on the manhole covers, leading to tilting of the manhole base. Settlement of the manhole base is difficult to detect with the naked eye and can easily lead to accidents. Currently, the commonly used anti-settlement manhole bases on the market use fixed concrete bases. Although these can slow down settlement, they cannot self-adjust and level. Manual leveling requires road closures, which is time-consuming, labor-intensive, and affects vehicle traffic. Utility Model Content

[0004] This utility model provides an adjustable anti-settlement manhole cover for municipal engineering, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides an adjustable anti-settlement manhole cover for municipal engineering, comprising:

[0007] The manhole cover, manhole base, connector, manhole casing, and adjusting ring are provided. The manhole cover and manhole base are connected by the connector. The manhole base is installed at the entrance of the manhole casing. The adjusting ring is fixedly installed on the arc surface of the manhole casing.

[0008] An adaptive adjustment device is disposed on the surface of an adjustment ring. The adaptive adjustment device includes a hydraulic airbag shell, a push block, a baffle, a support ring, a hydraulic damper, a spring, a bearing, and a sleeve. The bearing is fixedly connected to the inner wall of the support ring and to the arc surface of the sleeve. The arc surface of the hydraulic damper has a first thread, and the inner surface of the sleeve has a second thread, with the first and second threads meshing. A spring is fitted onto the arc surface of the hydraulic damper, and a pressure plate is fixedly connected to one end of the spring. The surface of the pressure plate is fixedly connected to the sleeve. The hydraulic damper is fixedly connected to the inner wall of the support ring. The support ring is fixedly connected to the surface of the hydraulic airbag shell, and the interior of the hydraulic airbag shell contains low-temperature resistant hydraulic oil. The push block is slidably connected to the inner wall of the hydraulic airbag shell and fits against the surface of the well base. The baffle is fixedly connected to the inner surface of the hydraulic airbag shell, and a connecting hole is formed on the surface of the baffle.

[0009] Through the above technical solution, by setting an adaptive adjustment device, when a vehicle runs over the manhole cover, the pressure borne by the manhole cover is transmitted to the support ring. The support ring compresses the hydraulic damper, at which point the thread on the sleeve meshes with the thread on the hydraulic damper, causing the sleeve to rotate. At the same time, the pressure plate on the sleeve compresses the spring, thereby relieving the transmitted force and extending the life of the manhole seat. When the manhole seat is uneven, it will cause local pressure to rise. The hydraulic oil in the high-pressure area inside the hydraulic airbag shell will flow to the low-pressure area through the connecting hole. Under the push of the push block, the manhole seat is leveled, thereby reducing manual maintenance, avoiding accidents caused by manhole seat settlement, and thus alleviating traffic pressure.

[0010] Furthermore, the adaptive adjustment device also includes four support plates, which are connected to the adjustment ring via screws. The surface of each support plate is fixedly connected to a hydraulic damper and a spring. A screw is fixedly connected to the surface of each support plate. The surface of the adjustment ring has four holes. The size of the screw matches the size of the holes in the adjustment ring. A nut is threaded onto the threaded surface of the screw.

[0011] The above technical solution allows for the fixation of hydraulic damping and adjusting ring by setting a screw.

[0012] Furthermore, an injection valve is fixedly connected to the surface of the hydraulic airbag shell, and a third sealing ring is fixedly connected between the injection valve and the hydraulic airbag shell.

[0013] The above technical solution allows hydraulic oil to be added to the inside of the hydraulic airbag housing via the injection valve, and the third sealing ring ensures the seal between the injection valve and the hydraulic airbag housing, preventing liquid leakage.

[0014] Furthermore, two retaining rings are fixedly connected to the surface of the hydraulic airbag shell, and a first limiting block is fixedly connected to the surface of the push block. The reserved size between the two retaining rings is adapted to the size of the push block, and the size of the first limiting block is larger than the reserved space between the two retaining rings and adapted to the internal size of the hydraulic airbag shell.

[0015] The above technical solution, by setting a retaining ring and a first limiting block, can restrict the push block and prevent it from falling off.

[0016] Furthermore, a first rubber pad is fixedly connected to the surface of the push block, and two second rubber pads are fixedly connected to the surface of the baffle.

[0017] Through the above technical solution, the first rubber pad can reduce the wear between the push block and the well seat, and the second rubber pad can achieve the sealing of the inside of the hydraulic airbag shell.

[0018] Furthermore, the surface of the adjusting ring has four circular grooves, the surface of the support ring is fixedly connected to four brackets, the surface of the brackets is rotatably connected to a telescopic rod, the output end of the telescopic rod is fitted with a universal ball joint, the size of the universal ball joint is adapted to the size of the groove of the adjusting ring, and the surface of the support ring is fixedly connected to four second limiting blocks.

[0019] The above technical solution allows for auxiliary support of the well base using telescopic rods.

[0020] Furthermore, a first sealing ring is fixedly connected to the inlet of the well base, and a second sealing ring is fixedly connected to the inlet of the well shaft.

[0021] The above technical solution ensures the seal between the manhole cover and the manhole base by using the first sealing ring, and the seal between the manhole base and the manhole casing by using the second sealing ring.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] 1. This utility model, by setting an adaptive adjustment device, allows the manhole cover to transmit the pressure it bears to the support ring when a vehicle runs over it. The support ring then compresses the hydraulic damper, causing the thread on the sleeve to mesh with the thread on the hydraulic damper, resulting in the sleeve rotating. Simultaneously, the pressure plate on the sleeve compresses the spring, thereby relieving the transmitted force and extending the life of the manhole seat. When the manhole seat is uneven, it can cause local pressure to rise. The hydraulic oil in the high-pressure area inside the hydraulic airbag shell will flow to the low-pressure area through the connecting hole. Under the push of the push block, the manhole seat is leveled, thereby reducing manual maintenance, preventing accidents caused by manhole seat subsidence, and alleviating traffic pressure.

[0031] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figures 1 to 5As shown, an embodiment of this utility model provides an adjustable anti-settlement manhole cover for municipal engineering, comprising: a manhole cover 1, a manhole base 2, a connecting piece 3, a manhole shaft 4, and an adjusting ring 5. The manhole cover 1 and the manhole base 2 are connected by the connecting piece 3. The manhole base 2 is installed at the inlet of the manhole shaft 4. The adjusting ring 5 is fixedly installed on the arc surface of the manhole shaft 4. An adaptive adjustment device 8 is disposed on the surface of the adjusting ring 5. The adaptive adjustment device 8 includes a hydraulic airbag shell 801, a push block 804, a baffle 808, a support ring 811, a hydraulic damper 814, a spring 818, a bearing 812, and a sleeve 813. The bearing 812 is fixedly connected to the inner wall of the support ring 811, and the tilt angle compensation range of the support ring 811 is ±10°. The bearing 812 is fixedly connected to the arc surface of the sleeve 813. The arc surface of the hydraulic damper 814 is provided with a first thread 815, and the inner surface of the sleeve 813 is provided with a second thread 816. Furthermore, the first thread 815 and the second thread 816 mesh with each other. A spring 818 is fitted onto the arc surface of the hydraulic damper 814, and the elastic coefficient of the spring 818 is 120 N / mm. One end of the spring 818 is fixedly connected to a pressure plate 817, and the surface of the pressure plate 817 is fixedly connected to the sleeve 813. The hydraulic damper 814 is fixedly connected to the inner wall of the support ring 811, and the support ring 811 is fixedly connected to the surface of the hydraulic airbag shell 801. The hydraulic airbag shell 801 is made of 304 stainless steel with a pressure resistance rating of 1.6 MPa, and the interior of the hydraulic airbag shell 801 contains low-temperature resistant hydraulic oil. The push block 804 is slidably connected to the inner wall of the hydraulic airbag shell 801, and the push block 804 is in contact with the surface of the well seat 2. The baffle 808 is fixedly connected to the inner surface of the hydraulic airbag shell 801, and the surface of the baffle 808 is provided with a connecting hole 810, and the diameter of the connecting hole 810 is 3 mm to ensure a pressure difference ≥ 0.Flow is triggered at 5MPa. Before installing the well seat 2, the operator can pull out the telescopic rod 822 on the bracket 821, so that the universal ball joint 823 abuts against the ground. At this time, the telescopic rod 822 abuts against the second limit block 824, which can stabilize the well seat 2 and prevent it from tilting. Before use, hydraulic oil is injected into the hydraulic airbag housing 801 through the injection valve 806. The telescopic rod 822 is then retracted, so that the universal ball joint 823 is placed into the groove on the adjusting ring 5. During use, the vehicle will press on the well cover 1, and the well cover 1 will transmit the pressure to the well seat 2. The well seat 2 will then transfer the pressure. The force is transmitted to the hydraulic airbag housing 801, which in turn transmits the force to the support ring 811. The support ring 811 then compresses the hydraulic damper 814 and the sleeve 813. At this time, the second thread 816 on the sleeve 813 engages with the first thread 815 on the hydraulic damper 814, causing the sleeve 813 to rotate and move downward on the bearing 812. Simultaneously, the pressure plate 817 on the sleeve 813 compresses the spring 818, which transmits the pressure to the support plate 819. The support plate 819 then transmits the pressure to the adjusting ring 5, thus relieving the force exerted by the vehicle on the manhole cover 1. To extend the lifespan of the manhole cover 2, when the manhole cover 2 is uneven, it will press against the push block 804 on the hydraulic airbag housing 801, causing a local pressure increase in the hydraulic airbag housing 801. The hydraulic oil in the high-pressure area inside the hydraulic airbag housing 801 will flow towards the low-pressure area through the connecting hole 810 of the baffle 808. Under the push of the push block 804 in the low-pressure area, the manhole cover 2 will be automatically leveled. By setting an adaptive adjustment device 8, when the vehicle runs over the manhole cover 1, the manhole cover 1 will transmit the pressure it bears to the support ring 811. The support ring 811 will compress the hydraulic damper 814. When the threads on the sleeve 813 engage with the threads on the hydraulic damper 814, the sleeve 813 rotates. Simultaneously, the pressure plate 817 on the sleeve 813 compresses the spring 818, thereby relieving the transmitted force and extending the life of the well seat 2. When the well seat 2 is uneven, it causes a localized increase in pressure. The hydraulic oil in the high-pressure area inside the hydraulic airbag housing 801 flows towards the low-pressure area through the connecting hole 810. Driven by the push block 804, the well seat 2 is leveled, reducing manual maintenance, preventing accidents caused by well seat 2 settling, and thus alleviating traffic pressure.

[0033] like Figures 3 to 5As shown, the adaptive adjustment device 8 also includes four support plates 819. The four support plates 819 are connected to the adjustment ring 5 via screws 820. The surface of the support plates 819 is fixedly connected to the hydraulic damper 814, and the surface of the support plates 819 is fixedly connected to the spring 818. The screws 820 are fixedly connected to the surface of the support plates 819. The surface of the adjustment ring 5 has four holes. The size of the screws 820 matches the size of the holes in the adjustment ring 5. Nuts 825 are threaded onto the threaded surface of the screws 820. By setting the screws 820, the hydraulic damper 814 and the adjustment ring 5 can be fixed. The surface of the hydraulic airbag shell 801... A liquid injection valve 806 is fixedly connected, and a third sealing ring 807 is fixedly connected between the liquid injection valve 806 and the hydraulic airbag housing 801. Hydraulic oil can be added to the inside of the hydraulic airbag housing 801 through the liquid injection valve 806. The third sealing ring 807 ensures the seal between the liquid injection valve 806 and the hydraulic airbag housing 801, preventing liquid leakage. Two retaining rings 802 are fixedly connected to the surface of the hydraulic airbag housing 801, and a first limiting block 803 is fixedly connected to the surface of the push block 804. The reserved size between the two retaining rings 802 is adapted to the size of the push block 804, and the size of the first limiting block 803 is larger than that of the two retaining rings 802. The dimensions of the reserved space between 02 are adapted to the internal dimensions of the hydraulic airbag housing 801. By setting the retaining ring 802 and the first limiting block 803, the push block 804 can be restricted to prevent it from falling off. A first rubber pad 805 is fixedly connected to the surface of the push block 804, and two second rubber pads 809 are fixedly connected to the surface of the baffle 808. The first rubber pad 805 can reduce the wear between the push block 804 and the well seat 2, and the second rubber pads 809 can achieve the sealing of the inside of the hydraulic airbag housing 801. The surface of the adjusting ring 5 has four circular grooves, and the surface of the support ring 811 is fixedly connected to four brackets 821. The support 821 is rotatably connected to a telescopic rod 822, which has a maximum load capacity of 5 tons. The output end of the telescopic rod 822 is fitted with a universal ball joint 823, the size of which is compatible with the size of the groove of the adjusting ring 5. Four second limit blocks 824 are fixedly connected to the surface of the support ring 811. The telescopic rod 822 can provide auxiliary support for the well base 2. The inlet of the well base 2 is fixedly connected to a first sealing ring 6, and the inlet of the well shaft 4 is fixedly connected to a second sealing ring 7. The first sealing ring 6 can ensure the sealing between the well cover 1 and the well base 2, and the second sealing ring 7 can ensure the sealing between the well base 2 and the well shaft 4.

[0034] In this embodiment of the utility model, before installing the manhole base 2, the operator can pull out the telescopic rod 822 on the bracket 821, so that the universal ball joint 823 abuts against the ground. At this time, the telescopic rod 822 abuts against the second limiting block 824, which can stabilize the manhole base 2 and prevent it from tilting. Before use, hydraulic oil is injected into the hydraulic airbag housing 801 through the injection valve 806. The telescopic rod 822 is then retracted, so that the universal ball joint 823 is placed into the groove on the adjusting ring 5. During use, the vehicle will press on the manhole cover 1, and the manhole cover 1 will transmit the pressure to the manhole base 2. The manhole base 2 will transmit the pressure to the hydraulic airbag housing 801, and the hydraulic airbag housing 801 will transmit the force to the support ring 811. The support ring 811 will compress the hydraulic damper 814 and the sleeve 813. At this time, the sleeve 813... The second thread 816 on sleeve 13 meshes with the first thread 815 on hydraulic damper 814. Sleeve 813 rotates and moves downward on bearing 812. At the same time, pressure plate 817 on sleeve 813 compresses spring 818. Spring 818 transmits pressure to support plate 819. Support plate 819 finally transmits pressure to adjusting ring 5. In this process, the force applied by the vehicle to manhole cover 1 is relieved, extending the life of manhole seat 2. When manhole seat 2 is not level, it will compress push block 804 on hydraulic airbag housing 801, causing local pressure increase in hydraulic airbag housing 801. Hydraulic oil in high-pressure area inside hydraulic airbag housing 801 will flow to low-pressure area through connecting hole 810 of baffle 808. Under the push of push block 804 in low-pressure area, automatic leveling of manhole seat 2 is achieved.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
