Abstract
Description
The present invention relates to a manhole, and more specifically, the manhole cover can be opened by only one operator by a simple operation, and the manhole locking device is easy to operate even in case of corrosion by long time, and overflows from the sewer pipe during the rainy season. The present invention relates to a manhole that can prevent the manhole cover from being removed by rainwater.
In general, a manhole is installed on a road to inspect or manage facilities such as water and sewage pipes, city gas pipes, communication facilities, and electric facilities buried underground, and the manhole is mainly manufactured using cast iron, and is used for pedestrians or vehicles. The manhole cover is installed as an opening and closing means to allow the worker to enter and exit the manhole in case of emergency.
The conventional manhole as described above is composed of a manhole body installed on the ground and a manhole cover seated on the manhole body to block holes. The conventional manhole structure is composed of a manhole body provided with a locking jaw in a cylindrical shape with an open center, and a manhole cover seated on the locking jaw.
However, in the conventional manhole configuration, the manhole cover is merely placed on the locking jaw of the manhole body so that the vehicle is separated by an impact when the vehicle passes at a high speed. In this case, the detached cover travels around the vehicle. There is a possibility that it may act as a cause of an accident, and the manhole body opened by the cover is detached may cause pedestrians to fall out or wheels of the vehicle may fall, causing a big accident.
In addition, there was a problem that the manhole cover is naturally removed due to repeated impact.
In this regard, the technology related to the safety manhole structure is disclosed as Korea Patent Publication No. 10-2011-0025507, but by inserting the protrusion key provided on one side of the manhole cover into the insertion groove by rotation to the exact position of the heavy manhole There is a problem that is difficult to rotate.
In addition, there is a problem that takes a long time to open the manhole cover due to corrosion or foreign matter between the protruding key and the insertion groove by a long time.
The present invention has been made to solve the above problems, an object of the present invention is to provide a manhole to prevent the removal of the manhole cover is inserted into the lower end of the support portion by the rotation of the support portion inside the manhole body.
In addition, the insertion hole is provided in a tapered shape in which the thickness thereof becomes thicker from one side to the other side, and the insertion hole is in close contact with the lower end of the support to provide a manhole in which the position of the manhole cover can be stably fixed.
The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems to be solved by the present invention, which are not mentioned here, can be clarified to those skilled in the art from the following description It can be understood.
The manhole according to the present invention is provided with a polygonal manhole body through which a center is penetrated and at least one support part formed by protruding along the inner surface of the manhole body, and a first insertion groove having a polygonal shape, and protruding from both ends. It is formed in the shape of the rotating portion and the disc is provided with the insertion hole is formed, the manhole cover is provided in the center of the circular second insertion groove and the top is provided with the groove into which the equipment is inserted, the upper portion is cylindrical shape and the lower portion is the first insertion And an operation part formed to be multi-stage in a polygonal column shape corresponding to the groove, wherein the operation part has a lower polygonal column inserted into the first insertion groove, and an upper cylinder inserted into the second insertion groove. The insertion hole is moved to the lower end of the support by the rotation of the negative portion is characterized in that the manhole cover is not opened.
One side of the support and the inside of the manhole body, characterized in that the first movement preventing and restraining the movement of the rotating part is provided respectively.
On the upper end of the manhole cover, a third insertion groove having an inclined surface inwardly is provided to insert a tool necessary for opening the manhole cover, and on the lower end of the manhole cover, the second movement preventing device is inserted to the manhole A fourth insertion groove is provided to restrain the movement of the cover.
It is formed in the 'c' shape is inserted into the lower portion from the upper end of the manhole cover is provided on the third movement preventing and restraining the movement of the rotating portion and the upper end of the manhole cover, the fifth insertion groove into which the third movement preventing opening is inserted And a release preventing device inserted into an end of the third movement preventing device to prevent the third movement preventing device from escaping to the outside of the manhole cover, and fastened to an end of the third movement preventing device so that the release preventing device moves to the third movement. It characterized in that it comprises a nut for preventing the departure from the prevention.
The insertion hole is formed in a tapered shape that increases in thickness from one side to the other side, characterized in that the upper end is formed with a projection to reduce the frictional force with the support.
One side of the manhole body on which the manhole cover is seated, characterized in that the mounting groove is further provided to reduce the contact surface between the manhole cover and the manhole body.
By the means for solving the above problems, the manhole according to the present invention, the insertion hole is inserted into the lower end of the support portion by the rotation of the support portion inside the manhole body has an effect of preventing the manhole cover from being removed without opening the manhole cover.
In addition, the insertion hole is provided in a tapered shape, the thickness of which becomes thicker from one side to the other side, and a protrusion is formed at the upper end of the insertion hole to facilitate insertion of the insertion hole into the lower end of the support, and at the same time, the frictional force with the support is reduced, so that it can be operated with a small force. And, the insertion hole is in close contact with the bottom of the support has the effect that the position of the manhole cover can be fixed stably.
