Description

Truss type double-scraper mud scraper Technical Field The invention relates to the technical field of dredging of steel slag sedimentation tanks, in particular to a truss type double-scraper mud scraper. Background Because the steel slag particles are heavier and are easy to harden, the ground of the sedimentation tank is uneven, so that the efficiency of conventional dredging equipment such as a mud scraper is low in the operation process, the equipment operation process and the ground scratch generate great noise, and meanwhile, the precipitated steel slag mud is difficult to effectively remove. Along with the increase of slag silt leading to the surface of water turbid, hardly observe sedimentation tank inside condition, former single track scraper means returns when promoting, very easily collides with sedimentation tank lateral wall, very easily causes equipment damage, has increased maintenance cost and downtime. In order to solve the problems, the conventional method is to mechanically limit the sludge scraper, and meanwhile, a temporary scraping plate is additionally arranged at the rear end of the sludge scraping device, so that collision with the side wall of the sedimentation tank during lifting of the scraping plate device is avoided, and after a period of production, heavy mechanical equipment such as an excavator and the like is used for manually cleaning the part which is not scraped by the sedimentation tank. However, this method is not only time-consuming and labor-consuming, but also presents a certain safety risk. In addition, frequent shutdown cleaning also seriously affects the continuity and efficiency of production, and becomes a big bottleneck for restricting the economic benefit of steel production enterprises. Therefore, how to effectively manage and clean the steel slag sludge in the sedimentation tank, reduce the influence on production equipment, reduce maintenance cost, and improve production efficiency at the same time becomes a problem to be solved urgently. In view of this current situation, there is a need to explore more efficient, environmentally friendly solutions to address the various challenges presented by steel slag sludge treatment. Disclosure of Invention The invention aims at solving at least one of the technical problems in the prior art and provides a truss type double-scraper mud scraper. In order to achieve the above purpose, the present invention adopts the following technical scheme: The truss type double-scraper mud scraper comprises a guide rail fixedly arranged at the top of a sedimentation tank and a truss car movably arranged on the guide rail, wherein the truss car comprises trusses which are movably arranged on the guide rail through driving wheel sets and driven wheel sets, a transmission device used for driving a plurality of driving wheel sets is arranged at the rear side of each truss, a double-scraper mud scraping device is arranged at the bottom of each truss through a lifting device, the transmission device comprises a speed reducing motor arranged at the rear side of the top of each truss, a small sprocket is arranged on an output shaft of the speed reducing motor, driven sprocket is connected with driven wheel sets through chains, two ends of each driven sprocket set are respectively connected with a transmission shaft through a coupling, the tail ends of each transmission shaft are connected with the driving wheel sets through the coupling, each driven wheel set comprises driven wheels, a bearing seat, the driven wheels are connected with the trusses through the bearing seats, a winding drum of each winding machine is connected with the double-scraper mud scraping device through the winding machine transmission device, the winding drum of each winding machine is provided with two supporting rods which are arranged at the front sides of the tops of the trusses, the two supporting rods are arranged at the bottoms of the two supporting rods which are in a mutual mode, and the supporting rods are arranged at the bottoms of the two supporting rods which are corresponding to the two supporting rods and are arranged at the bottoms of the two supporting rods.
