A kind of leveling style conveyer
Technical field
The present invention relates to a kind of conveyer, be specifically related to a kind of leveling style conveyer.
Background technology
As the patent No. be 200920138405.6 gulp down pipe adjustable type conveyer because the gradient that adopts leg-of-mutton bracing frame fluid,matching cylinder pressure to come lift and conveyer, this lifting mechanism is stressed not to be concentrated; Starting is risen heavier, the stressed increasing of frame, the inertia impact that descending speed is very fast; Cause frame phenomenon of rupture to occur; And that the subsidiary conveyer structure in the feeding end cylinder lower end of this conveyer moves is difficult, accounts for the mechanism space, operation inconvenience more; And the driving pulley of transmission device and driven pulley system adopt smooth rod member (tubing) welding tractor system to form; The difficult arch in the middle part of its belt pulley cylinder clearly; Reduce belt stability, and it is less to the belt not enough drive friction force of angle that detours, needs very tightly to understand expanded motor load by what belt was opened; Also have the space, skewed slot road on the oblique carrying roller end cap excessive, occur phenomenon or the like the shortcoming of kinking easily.
Based on above-mentioned technical matters, those skilled in the art have developed a kind of structure-improved that gulps down pipe adjustable type conveyer again, and the patent No. is 201020688502.5; Though this structure-improved that gulps down pipe adjustable type conveyer can be used as conveyer gradient lifting mechanism through hydraulic jack, its vertical mechanism is stressed more concentrated, and the front wheel frame holding capacity is more direct; Significantly reduced the fracture defect rate of lifting mechanism; And because hydraulic jack is the pattern of socket, promptly the push rod caliber of upper end is little, and lower end push rod caliber is big; During rising, the slow earlier back of ascending velocity is fast; During decline, speed first quick and back slow; Reduce inertia impact, guaranteed the steady up-down of mechanism, improve the life-span of mechanism.But when rising, it is fast slow earlier back to occur, when causing stopping to rise; Impact to hydraulic tubing and mechanism is bigger; Can't further improve the service life of this conveyer, and this structure-improved that gulps down pipe adjustable type conveyer is not provided with anti-fall guard, in case when pipeline leakage of oil or control cock fault and draining; Conveyer falls suddenly, causes the damage and the personal safety accident of conveyer easily.
