The invention discloses an integrated type hydraulic belt tensioning device of a bucket-wheel stacker-reclaimer. The integrated type hydraulic belt tensioning device comprises a lead screw device, trolley devices, anti-tipping devices, standard tensioning rollers, hydraulic oil cylinder devices and belts, and is characterized in that the trolley devices are symmetrically fixed to the two sides of a cantilever beam of the bucket-wheel stacker-reclaimer, each trolley device comprises a frame and a wheel, rails fixed to the cantilever beam are arranged at the bottoms of the wheels, two bearing pedestals of the standard tensioning rollers are fixed to the frames respectively, the belts are wound around rubber faces of the standard tensioning rollers, the lead screw devices are symmetrically arranged on the two sides of one end of the cantilever beam respectively, one ends of the lead screw devices are fixed to the cantilever beam, the other ends of the lead screw devices are connected with shaft end bases I on one sides of the frames, the hydraulic oil cylinder devices are symmetrically arranged on the two sides of the other end of the cantilever beam respectively, one ends of the hydraulic oil cylinder devices are fixed to the cantilever beam, and the other ends of the hydraulic oil cylinder devices are connected with shaft end bases II on the other sides of the frames. By means of the integrated type hydraulic belt tensioning device, potential safety hazards are eliminated, the work time of replacing and maintaining the tensioning rollers is shortened, and the overhaul work efficiency is improved.
Description
technical field [0001] The invention relates to a belt tensioning device of a bucket wheel stacker and reclaimer, in particular to an integrated belt hydraulic tensioner of a bucket wheel stacker and reclaimer. Background technique [0002] At present, the hydraulic tensioning device of the bucket-wheel stacker-reclaimer in the prior art, that is, the hydraulic cylinder pulls the roller with a special structure on the fixed slideway to realize the tensioning stroke. This form has potential safety hazards and high cost of the cylinder. It is inefficient to replace the tension roller, and the slideway has high processing precision, so it is difficult to manufacture. [0003] First of all, safety issues. The existing hydraulic tensioning device works. When the hydraulic cylinder pushes the roller to the specified stroke position, the cylinder will lock the position of the roller under pressure. If the hydraulic system releases pressure for some reason, the drum will move, whic...
