Opening method of multi-functional horizontal rotary opening manhole cover

Abstract

The invention relates to a multifunctional horizontal rotating opening type inspection well lid and an opening method, and belongs to the technical field of inspection well lid equipment. According to the technical scheme, the multifunctional horizontal rotating opening type inspection well lid comprises a well lid base (1), H-shaped pins (4), a well lid body (5), a screw pin and a T-shaped anti-theft lock, a T-shaped guide groove (2) is formed in the well lid base (1), the well lid body (5) is connected with the well lid base (1) through the screw pin, the screw pin penetrates through the T-shaped guide groove (2), a rubber gasket (14) is arranged between the contact faces of the well lid body (5) and the well lid base, two or more H-shaped pins (4) are arranged on the well lid body (5) in the circumferential direction, and the T-shaped anti-theft lock matched with the T-shaped guide groove in shape is arranged on the T-shaped guide groove. The multifunctional horizontal rotating opening type inspection well lid and the opening method have the advantages that in the horizontal rotating opening or closing process, stereoscopic space is saved, meanwhile, personal injury accidents are prevented from being caused by accidental closing under the opening state, lifting and noise caused when vehicles and pedestrians pass through can be effectively prevented, and meanwhile the aim of theft prevention is achieved.

Description

technical field [0001] The invention relates to a method for opening a multifunctional horizontally rotating and opening inspection shaft cover, which belongs to the technical field of inspection shaft cover equipment. Background technique [0002] With the needs of urban modernization and development, more and more overhead lines have been replaced by cable entry projects. While it beautifies the city, the manhole cover on the inspection well is lost and damaged, which has also buried many hidden dangers for the safety of urban roads. In addition, since the inspection shaft channel used by the supply facilities is inevitably located on the traffic road, when vehicles and pedestrians pass the inspection shaft cover, usually the focus point cannot effectively coincide with the center of gravity of the manhole cover, which will cause the manhole cover to warp, which is easy to cause damage to the manhole cover. Vehicles and pedestrians pose a danger. Even if the manhole cove...

Problems solved by technology

While it beautifies the city, the loss and damage of the manhole cover on the inspection well has also laid many hidden dangers for the safety of urban roads.

In addition, since the inspection shaft channel used by the supply facilities is inevitably located on the traffic road, when vehicles and pedestrians pass the inspection shaft cover, usually the focus point cannot effectively coincide with the center of gravity of the manhole cover, which will cause the manhole cover to warp, which is easy to cause damage to the manhole cover. Danger to vehicles and pedestrians

Even if the manhole cover does not cause any damage to vehicles and pedestrians, it will cause a lot of noise when it falls freely

[0003] At present, most of the anti-theft manhole covers are opened in a three-dimensional way. After opening, they are limited by the position of the hinges and cannot be effectively laid flat. It is very easy to cause accidental closure of the manhole cover and cause danger.
