Abstract

The present invention relates to an unmanned dredging device, which dredges and discharges deposit soil or sewage in a sewer pipe. Specifically, the unmanned dredging device is possible to discharge the sewage or the deposit soil in the sewer pipe to the outside by sweeping the same with a rotating brush (50) even while an operator doesn′t directly enter the sewer pipe by being operated by supplying pressure oil discharged from an electric hydraulic pump (30) to a main hydraulic motor (25), boom cylinders (43, 44) and a rotating brush operating hydraulic motor (52) by operation of hydraulic control valves (32 to 35).

Description

A dredging machine for a drain pipeline

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewer dredging device, and more particularly, to an apparatus for dredging sedimentary soil inside a sewage pipe as a dredging mechanism mounted on a bogie while driving a self-propelled bogie into a sewage pipe where dirt and earth and sand are deposited.

In the sewer pipe, a large amount of soil is carried and deposited by heavy rains, and this sediment not only impedes smooth runoff, but also causes flooding or flooding during heavy rains. In addition, since sludge in which various harmful substances are deposited contaminates water quality or soil, it is essential to periodically dredge the inside of sewer pipes. Conventionally, a person directly enters a culvert by a sewer pipe and dredged the soil and various sediments deposited on the culvert. However, there is a difficulty in dredging work such as the worker cannot work for a long time due to the gas remaining from the sediment accumulated in the sewage pipe culvert or from flowing out from the outside.

As described above, the conventional sewage pipe dredging method by a worker has the above-described problem, and a technique for dredging dirt or soil inside a sewer pipe by introducing an unmanned dredging device is disclosed in Patent Document 1 below.

The conventional dredger disclosed in Patent Document 1 includes a bucket 130 at the tip of the traveling body, and when the traveling body travels, the deposited sludge or soil is pushed into the bucket 130 by the driving force of the traveling body. It is. Therefore, in such dredgers, if the driving force is not large, that is, the bucket 130 is not large enough to drive the dredged soil, the driving is prevented from dredging soil is prevented from traveling inside the sewer pipe, dredging operation was not possible.

In order to solve this problem, a driving mechanism (mainly a motor) having performance and output must be installed in the traveling body so as to increase driving propulsion of the traveling body, which is large in volume and size of the entire dredging device, There is a problem that can not dredging.
