Dredging tool for operation outside closed conduit
The invention relates to a dredging tool for operation outside a closed conduit. The dredging tool for operation outside the closed conduit comprises two winches, a transformation support for supporting and trailers. The two winches are arranged on the outer sides of adjacent inspection ports of the closed conduit respectively. The transformation support for supporting comprises an upper transverse supporting rod, a longitudinal upper supporting rod and a longitudinal lower supporting rod. The longitudinal upper supporting rod and the longitudinal lower supporting rod are hinged to the upper transverse supporting rod. The top end of the longitudinal upper supporting rod and the top end of the longitudinal lower supporting rod are each provided with a pulley. A traction rope of each winch is wound around the two pulleys and connected with the front end and the rear end of the corresponding trailer. The dredging tool greatly enhances safety of dredging operation; constructors only need to concentrate on the inspection ports for operation and do not need to enter the closed conduit; an original closed space operation mode of closed conduit dredging is changed, and the harm that personnel are poisoned and stifled is avoided; the safety coefficient of operation is increased; and a powerful guarantee is provided for smooth operation of the dredging operation of the closed conduit, and operation cost is reduced.
