Downhole slag dredging grab bucket mechanism for fecal suction truck

Abstract

The invention provides a downhole slag dredging grab bucket mechanism for a fecal suction truck. The downhole slag dredging grab bucket mechanism comprises 4-6 upper rotating arms, each upper rotating arm is provided with two capturing pieces, the capturing pieces form an L shape by adopting steel plates, the two capturing pieces are symmetrically arranged on two sides of the upper rotating arms, the corner positions of the capturing pieces are hinged to the lower ends of the upper rotating arms, short arms (extending inwards) at the lower ends of the capturing pieces are grabhook function parts, a hydraulic cylinder is placed in a center mounting hole of an upper fixing plate, and a lower movable plate is fixedly connected with a piston rod of the hydraulic cylinder. The upper ends of the upper rotating arms are hinged to first supports (evenly distributed along the circumference on the lower plane of the upper fixing plate), the lower movable plate is located in a circumference inner cavity formed by the upper rotating arms, and the upper ends of the capturing pieces are hinged to second supports (evenly distributed along the circumference on the lower plane of the lower fixing plate). A plurality of capturing units surrounded inside and outside are arranged, the capturing pieces are synchronously opened or tightened along with the rotating arms, and the downhole slag dredging grab bucket mechanism moves into a downhole conveniently, facilitates slag dredging and has the advantages of being small in size and simple in structure.

Description

technical field [0001] The invention relates to all fecal suction trucks realizing the function of sucking feces, in particular to an underground slag grabbing mechanism for the fecal suction truck. Background technique [0002] Despite the unprecedented development of urbanization in our country, the sewage suction trucks used for pipeline maintenance are unable to adapt to the process of extracting large solid waste inside the pipeline; at present, there have been multi-lobed hydraulic grabs used on the ground, but their volume is huge , It is impossible to enter (storage) underground to fish for slag, and the cleaning of large solid waste in the underground still depends on manual work. Contents of the invention [0003] In order to ensure small size, easy access to the underground slag, and to realize the grasping of underground solid waste, instead of manual labor, the present invention proposes an underground slag grab mechanism for a fecal suction vehicle.
