Movable type hydraulic trash-cleaning machine

Abstract

The invention relates to a movable type hydraulic trash-cleaning machine. The machine mainly comprises a travelling mechanism, a winding mechanism and a scraper bucket mechanism, wherein a travelling motor of the travelling mechanism runs in a track to drive the winding mechanism and the scraper bucket mechanism to move and work; a driving motor of the winding mechanism drives a wire rope reel to rotate and reel and release a wire rope through a driving shaft to realize the lifting of a deslagging scraper bucket; a driving chain wheel on the driving shaft of the winding mechanism drives a driven chain wheel through a chain to drive an oil tube winding drum to rotate and reel and release an oil tube, so that oil is supplied to a hydraulic oil cylinder to enable the deslagging scraper bucket to open and close; a clockwork spring is arranged on a driven shaft in the oil tube winding drum of the winding mechanism, when a trash-cleaning scraper bucket descends, the pre-tensioning force of the clockwork spring in the oil tube winding drum is released gradually, and when the trash-cleaning scraper bucket ascends, the clockwork spring of the oil tube winding drum is tightened gradually, so that the oil tube and the wire rope always descend and ascend synchronously and are consistent in tensioning and the phenomenon that the oil tube breaks away from the oil tube winding drum or is snapped is avoided; and therefore, the movable type hydraulic trash-cleaning machine has the advantages of safe and reliable running and long service life.

Description

technical field [0001] The invention relates to a sewage cleaning machine, in particular to a mobile hydraulic sewage cleaning machine, which is a mobile hydraulic sewage cleaning machine, which is used for cleaning dirt in multiple water inlet channels such as urban water supply, drainage, and water intake pumping stations, or on the grid surface of wide channels. Background technique [0002] The basic composition of the mobile hydraulic cleaning machine in the prior art is made up of traveling mechanism, slag removal rake bucket, lifting mechanism, hydraulic system and electric control system. The main working method is: the traveling mechanism moves to the upper part of the trash rack, the lifting mechanism puts down the slag removal rake bucket, and under the action of gravity, the slag removal rake bucket slides along the grid surface of the channel to the bottom of the channel, and the dirt intercepted by the grid surface is discharged from the top to the bottom of the...

Problems solved by technology

During this process, the oil supply and return pipelines of the hydraulic system and the rake bucket go down and up at the same time. This structure can simplify the underwater actuator and reduce the moving parts in contact with the sewage. Therefore, it is required that the oil supply and return pipelines and the wire rope lifting device must be synchronized. Due to the large difference in mechanical properties such as the diameter, rigidity, toughness, and radius of curvature of the oil pipe and the steel wire rope, the slack and tension of the oil pipe during the downward and ascent of the rake bucket vary, and even the oil pipe is detached from the oil pipe reel or is caught. The second is that the hydraulic system is installed on the slag removal bucket as a whole, relying on the bucket’s own weight to collect slag, and when it reaches the bottom of the trash rack, the underwater hydraulic system realizes the force-enhancing closure of the bucket. A fully submerged hydraulic drive system is used, which lacks safety in actual use, and because of its complex structure, the underwater cleaning mechanism is easy to cause dirt to be entangled and damaged underwater, which increases the difficulty of equipment maintenance and shortens the service life of the equipment
