The following description relates to a slide type cover opening / closing device for opening and closing a cover by a sliding method.

In general, a manhole is a hole that can be opened and closed by a person to manage and inspect various communication cables such as a top, a sewer, and a power line buried under the ground.

Manhole covers are placed on these manholes to prevent accidents.

A conventional manhole cover is simply mounted on an upper portion of a manhole and lifted and opened, or the manhole cover and the upper portion of the manhole are coupled by a hinge and are used to open and close about a hinge.

However, since the manhole cover is made of a metal material and is heavy in weight, a large number of manpower is required for opening and closing the manhole cover, which not only inconveniences the user, but also poses a problem in terms of work safety.

Especially, the hydraulic valve which is used for air supply in the underground hydrant valve box is equipped with a motorized valve that automatically opens and closes the valve that constitutes the leak detection system, and a transmission device for various measurement, and the internal equipment is inspected through opening and closing of the manhole cover In this case, since the size of the cover is much larger than that of a general manhole cover so as to withstand the weight of an aircraft, it is not only inconvenient to open and close the cover of the manhole cover, but also has a problem of stability. In addition, the waterproof function of the manhole cover is weak, and there is a great difficulty in managing the leak detection device composed of electronic parts due to rainwater or the like flowing into the manhole at the time of rainy weather.

In addition, when the manhole cover is opened and closed by using a hinge, the hinge portion can not withstand the weight of the manhole cover and is damaged, resulting in troublesome and troublesome maintenance and a work space capable of rotating the manhole cover up and down There is a problem that space efficiency is low.

Therefore, regardless of the size and weight of the manhole, it is required to open and close the manhole cover in a safe and efficient manner.

For example, Korean Patent Laid-Open Publication No. 2013-0089298 discloses a slide lock type manhole lid assembly for easily fastening an upper casing and a lower casing of a manhole by a sliding locking method by rotation.
