The present invention relates to a maintenance apparatus for sewage pipes, and more particularly, to a sewage pipe maintenance apparatus configured to repair a damaged part of the sewage pipe as well as cleaning the inside of the sewage pipe.

In general, sewage pipes are mostly buried underground to discharge various kinds of sewage, and branch pipes connected to the main pipes are connected to the main pipe where sewage is generated in order to collect the generated sewage and lead them to the terminal treatment plant or river.

After a certain period of time, such sewage pipes have a weight or soil contained in the sewage, which is deposited on the lower portion thereof, and the sediment becomes a sediment, and the sediment obstructs the flow of sewage, and thus, internal sediments should be removed regularly.

Background Art [0002] Conventionally, as a means for cleaning sewage pipes, a jet nozzle method using high pressure or a bucket reciprocating dog method for passing a bucket into a sewage pipe has been used.

However, the jet nozzle method has to be accompanied by excessive consumption of a power source for supplying high-pressure water, as well as a separate high power device in accordance with the driving, wasted a lot of power and fuel, economic loss, In particular, a vehicle such as a vehicle was used to transport a device with a high appearance and weight to a work position, but cleaning was not possible in a place where the work place was narrow enough to enter a vehicle.

In addition, the basket reciprocating traction method is installed on both sides of the wire dredger between the manhole and the manhole of a certain distance and connecting the basket between the wires on both sides while reciprocating the basket in the sewer pipe with separate power It is configured to remove the sediment, but it takes a long time, and also causes a great obstacle in the passage of pedestrians and vehicles, and because the appearance of the device is large, it must be transported using a vehicle and entry of vehicles such as narrow alleys The problem has been raised that it is impossible to work in difficult places.

Patent No. 192160, which was invented in view of such a problem and registered on June 15, 1999, has proposed a cleaner for entering a sewage pipe and removing sediments such as weight or soil deposited on the sewage pipe.

Such a cleaner has a proper structure to remove the sediment, but does not have a proper structure to repair the internal phenomenon of the sewage pipe or the leakage phenomenon that may occur at the connection between the main pipe and the branch pipe.

 The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a sewer pipe maintenance apparatus capable of maintaining as well as cleaning the inside of the sewer pipe.

Maintenance device of the present invention for achieving the above technical problem, the main body portion is installed with a wheel that is rotated by the power transmitted from a plurality of electric and reduction gear rotated in accordance with the operation of the hydraulic motor; And a rotating hydraulic motor connected and fixed to the main body, a rotating plate fixed to the rotating shaft of the rotating hydraulic motor, a plurality of operating cylinders fixed to the front surface of the rotating plate, and fixed to each rod of the plurality of operating cylinders.
