Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a combined manhole cover for municipal construction. Background Art

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] For example, the Chinese patent with publication number CN212078014U proposes a combined environmentally friendly manhole cover. The patent sets the telescopic slot and the telescopic rod to be arc-shaped, which can be well inserted during circular motion. The sealing plate can prevent foreign matter from entering the interior of the telescopic slot and causing blockage. The spring is set and the elastic force of the spring itself is used to increase the fixing effect of the two fixing rods. The sealing gasket is set to increase the sealing effect between the manhole cover and the wellhead. However, in this solution, since the application scope of manhole covers usually includes sewage pipelines, fire protection projects, power supply cables, etc., the common manhole covers are on the ground and level with the ground. After the manhole covers are used for a long time, vehicles may run over them and people may walk frequently, so that the manhole covers may be compacted. At this time, it may be difficult for the staff to move the manhole cover, which may affect the staff's disassembly of the manhole cover to repair the sewage pipelines and other facilities under the well.

[0004] For example, the Chinese patent with publication number CN208618457U proposes a new modular manhole cover. The patent adopts a square structure through the manhole ring, which is easy to install and has increased bearing capacity. The manhole cover adopts a truncated cone structure, which is more beautiful in appearance, has no edges and corners, and is safer. However, in this solution, since the application scope of manhole covers usually includes sewage pipelines, fire protection projects, power supply cables, etc., the common manhole covers are on the ground and level with the ground. After the manhole covers are used for a long time, vehicles may run over them and people may walk frequently on them, and the manhole covers may be compacted. At this time, it may be difficult for the staff to move the manhole cover, which may affect the staff's dismantling of the manhole cover to repair the sewage pipelines and other facilities underground.

The surfaces of the manhole cover body 2 and the mounting ring 1 are respectively coated with anti-rust paint.

[0029] Working principle: Please refer to Figure 1-Figure 5As shown, through the set manhole cover body 2, the staff installs the installation ring 1 on the wellhead, and then puts the manhole cover body 2 into the installation ring 1, and then the manhole cover body 2 will be placed on the top surface of the fixing ring 12, so as to facilitate the installation of the manhole cover body 2. At this time, the top surface of the manhole cover body 2 is level with the ground. After the manhole cover body 2 is used in public places for a long time, if the manhole cover body 2 is compacted and difficult to move out of the inside of the installation ring 1, first, the fixing column 8 is moved out of the threaded groove 11 and the fixing hole 7, so as to release the restriction of the stopper 4, and then the staff drives the limiting block 6 to move by moving the stopper 4, which can be The stopper 4 can be moved out of the auxiliary hole 3, thereby removing the obstruction of the auxiliary hole 3 by the stopper 4. At this time, the outer circular wall of the manhole cover body 2 can be seen through the auxiliary hole 3, and then the staff can use a tool such as a crowbar to put it into the disassembly groove 13 through the auxiliary hole 3, and then one end of the crowbar will enter the bottom surface of the manhole cover body 2, and then press the crowbar downward, so that the manhole cover body 2 can be lifted from the inside of the mounting ring 1, which is convenient for disassembly of the manhole cover body 2. The mounting ring 1, the manhole cover body 2, the fixing ring 12 and the stopper 4 are used in combination to prevent the manhole cover body 2 from being compacted by a vehicle and becoming difficult to disassemble.

[0030] By setting the handle 19, when the staff needs to move the manhole cover body 2 out of the interior of the mounting ring 1, the handle 19 is rotated to drive the rotating column 20 to rotate, and then the handle 19 can be rotated out of the interior of the placement groove 17, and then the staff holds the handle 19 to facilitate dragging the manhole cover body 2.

[0031] By setting the baffle 21, the staff puts the baffle 21 into the placement groove 17, and then the fixing block 24 will be placed inside the groove 17. When the position of the installation groove 23 coincides with the position of the limiting groove 22, the spring 25 will push the fixing block 24 to rebound, and then the fixing block 24 will enter the limiting groove 22, which can limit the baffle 21 to the inside of the placement groove 17, thereby facilitating the shielding of the handle 19 and preventing the handle 19 of the manhole cover body 2 from being stepped on by passers-by during use.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
