Description

{Opening and Closing Device for Underground Facility Check}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing apparatus for checking an underground facility, and more particularly, to an opening / closing apparatus for checking an underground facility.

In general, underground structures are underground passages that are constructed to be able to install driving parts, driven parts, power lines, communication lines, gas pipes, sewage pipes, etc. underground.

Therefore, in order to check the facilities installed in such underground structures, workers must go down to the underground through manholes installed at certain intervals.

In addition, at the entrance of the passageway constructed underground to inspect or install the facility facilities, a metal door that can be accessed by the operator is installed for installation work of the facility facilities, repair and inspection.

Conventionally, heavy doors are directly closed or opened by gravity, and many inconveniences are incurred. In addition, weak operators have difficulty in lifting or closing heavy doors.

On the other hand, sewage treatment plants and water purification plants are used to purify sewage and use them as used water. However, most of such sewage treatment plants or water treatment plants are disposed underground, so that a passage is formed in the underground for checking and repairing facilities.

And an entrance connected to the ground is shielded by the door to access the passage.

As shown in FIG. 1, the door 20 is a plate made of an iron plate and has a handle 21, which is opened and closed using a handle. Normally, the handle 21 is locked using a key or the like.

The operator can open and close the door 20 from the door 10 when inspection, repair, and the like are required.

However, as described above, the conventional general door is made of the iron plate material, and since the weight of the door is very large, the worker can not open the door alone, and many people open the door to open the door.

In addition, since the lid-type door is approximately 50 kilograms in weight, the worker directly lifts the door and then moves the door 10 a predetermined distance. Therefore, during the work, the worker's foot or the weight of the worker And the like.

Also, there is a problem that the place to be used is wet by sewage and the work environment is not good, and doors and doors are rusted, which makes it difficult to open and close.

For example, Patent Document 1 below discloses a " shutter type access device for a steel box inspection device for a bridge ".

A shutter type access device for a steel box inspecting device of a bridge according to the following Patent Document 1 is provided with a lower inspecting port for inserting / leaving and a reinforcing rib along the inner wall adjacent to the inserting / And a door for opening and closing the check port by the guide unit.

The guide unit is composed of two front rails linearly fixed on both inner ends of the check box along the longitudinal direction of the steel box, and two rear rails connected to the two front rails and passing over the reinforcing ribs And the door has a shutter structure that folds along the trajectory formed by the two front rails and the two rear rails when the door is opened and closed.

The following Patent Document 2 discloses an apparatus for opening / closing an underground wiring passage door.

In the opening and closing device for the underground wiring passage door according to the following Patent Document 2, an opening formed with a base for the rim is formed at the middle of a metal supporting frame formed by welding a plurality of reinforcing ribs and a wire net to the left and right, And the U-shaped arm is attached to the protrusion of the metal support frame by the pin so that the protrusion of the arm is attached to the piston rod and the pin of the cylinder that is attached to the support by the pin.
