Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to a manhole cover for municipal roads provided with a buffer structure. Background Art

[0002] With the advancement of rural urbanization, cities are developing at a high speed. In order to meet people's travel needs, road construction and renovation are indispensable, and what comes with it are underground pipelines. In the process of road construction, it is necessary to build pipelines underground to connect the drainage of various areas and various lines. In order to facilitate its maintenance, inspection ports will be opened within a certain distance and manhole covers will be installed. Manhole covers are an indispensable part of modern cities. They can effectively protect underground settings, inspect lines, and prevent facilities from being damaged and leaking due to the trampling of vehicles and pedestrians. Secondly, manhole covers can also maintain the flatness and safety of the road surface. The flatness and tightness of manhole covers are crucial for the driving of vehicles and the walking of pedestrians. When the manhole cover is loose, damaged or displaced, it will bring hidden dangers to road safety;

[0003] However, existing manhole covers generally do not have a buffer and anti-seismic structure. When a vehicle passes through the manhole cover, it will roll over the manhole cover and cause impact on the manhole cover, which will not only generate noise, but also cause the manhole cover to crack and be damaged, greatly reducing the service life of the manhole cover. Utility Model Content

[0004] The utility model aims to provide a manhole cover for municipal roads with a buffer structure to solve the problem of damage caused by impact when a vehicle passes over the manhole cover in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal road manhole cover with a buffer structure, comprising a manhole seat, a manhole sleeve, a round manhole cover, a pull rod and a handle, the outer surface of the manhole seat is penetrated and fixed with the manhole sleeve, and the outer surface of the manhole sleeve is penetrated and installed with a rotating shaft, the outer surface of the manhole sleeve is rotatably installed with a round manhole cover, the outer surface of the manhole sleeve is penetrated and installed with a pull rod, and the outer surface of the pull rod is rotatably installed with a handle, the inner part of the manhole sleeve is rotatably installed with a rotating shaft, and one end of the rotating shaft is fixedly installed with a first gear, and the inner part of the manhole sleeve is rotatably installed with a reducing gear. A speed roller is provided, and a second gear is fixedly installed at one end of the speed reduction roller, a first spring is arranged between the well casing and the pull rod, a rubber pad is arranged inside the well casing, and a pressure block is fixedly installed at the lower end of the rubber pad, a slider is slidably installed on the outer surface of the well casing, and a second spring is arranged between the slider and the well casing, and the slider is wedge-shaped, a third gear is rotatably installed inside the well casing, and a pin is slidably installed inside the well casing, and a tooth block is arranged on the outer surface of the pin, a groove is opened on the side surface of the round manhole cover, and a pattern is arranged on the outer surface of the round manhole cover.

[0006] Preferably, the well casing is fixedly installed on the inner side of the well seat, and the well casing is snap-fittedly connected to the round well cover, and the well casing and the round well cover are concentrically designed.

[0007] By adopting the above technical solution, the well casing can be firmly fixed in the ground through the well seat to prevent the well casing from moving.

[0008] Preferably, the pull rod is slidably connected to the well casing, and the outer surface of the lower end of the pull rod is in contact with the outer surface of the speed reduction roller.

[0009] By adopting the above technical solution, there is no need to worry about the wear of the pull rod and the deceleration roller causing the slow-down failure, because the first spring will always push one end of the pull rod toward the outer surface of the deceleration roller until the lower end of the pull rod is completely worn.

[0010] Preferably, the side surface of the handle is wedge-shaped, and the handle is rotatably connected to the pull rod.

[0011] By adopting the above technical solution, the handle can be lifted up and the pull rod can be pulled out by tools to prevent the protruding surface of the round manhole cover from causing harm to the driving of vehicles and pedestrians.

[0012] Preferably, the first gear is fixedly mounted on a side of the rotating shaft close to the pull rod, and the diameter of the first gear is smaller than the diameter of the second gear.

[0013] By adopting the above technical solution, the falling speed of the round manhole cover is reduced by the gear ratio of the first gear and the second gear.

[0014] Preferably, the deceleration roller is rotatably connected to the well casing, and the deceleration roller is installed at one end of the well casing away from the round manhole cover.

[0015] By adopting the above technical solution, the pull rod will be pressed against the deceleration roller through the first spring, thereby reducing the speed at which the round manhole cover is opened and preventing the round manhole cover from hitting the ground and causing damage to the rotating shaft.

[0016] Preferably, the pressing block is of conical design, and the side surface of the pressing block fits with the side surface of the sliding block, and the sliding block is slidably connected to the well casing.

[0017] By adopting the above technical solution, when the round manhole cover is impacted, the force of the impact will be reduced by the sinking of the rubber pad.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the municipal road manhole cover with a buffer structure:

[0019] 1. After the sewer is installed, close the round manhole cover, and the outer surface of the round manhole cover fits with the outer surface of the rubber pad. When the car passes over the round manhole cover, the round manhole cover presses down to drive the rubber pad down, and the pressure block moves down with the rubber pad to make the slider slide, and the second spring pushes the slider to make the rubber pad rise, so that the impact force is buffered and released through the rubber pad and the slider;

[0020] 2. When you need to open the round manhole cover, you only need to turn out the handle and lift the pull rod to easily open the round manhole cover. When the round manhole cover is opened to an angle perpendicular to the ground, the pull rod can be released. Through the friction between the pull rod and the deceleration roller, the round manhole cover slowly falls to the ground, preventing the round manhole cover from suddenly hitting the ground and causing the shaft to break;

[0021] 3. After the manhole cover has been used for a long time, the first spring will still push the pull rod out tightly, so that one end of the pull rod is always close to the deceleration roller. When the outer surface of the pull rod or the deceleration roller is worn, the first spring will still push the pull rod out, so that the surface fits tightly without worrying about wear.
