Passive hydraulic control linked error correcting machine
A passive hydraulic control linkage rectification machine which can rectify and prevent the run deviation of a conveyor belt consists of a hydraulic control detecting and driving system and a linkage rectification mechanism. The hydraulic control detecting and driving system consists of a detecting and driving wheel, an oil pump, a cylinder, a midpoint controlling station, a temperature controller and an oil pipe. The linkage rectification mechanism consists of discrete rollers, roller racks, a universal joint, an arm rod, a connecting rod, a pin and a frame. The hydraulic control detecting and driving system is used to detect the run deviation of the belt and simultaneously supplies power for driving the roller racks to deflect. When the belt runs deviated, the belt drives the detecting and driving wheel to rotate. The detecting and driving wheel drives the oil pump to strike the oil pressure to the midpoint controlling station. A logistic valve group of the midpoint controlling station controls the piston rod of the cylinder (4) to push or pull. The piston rod drives the linkage rectification mechanism to lead the roller (11) on the mechanism to deflect synchronously in the same direction. An angle is formed between the linear moving direction of the roller after the deflection and the moving direction of the belt, and the transverse friction of the belt generating during the above process drives the belt to run in the middle. The passive hydraulic control linkage rectification machine requires no power and hydraulic function and has the advantages of synchronous linkage, self-defecting, self-driving and self-system.

The invention discloses a separated friction support with adjustable horizontal two-way mechanical parameters. The support comprises a rotating plate, a longitudinal translation plate, a longitudinal friction cylinder, a two-way translation plate, a transverse friction cylinder and a fixed plate from top to bottom. Wherein a spherical crown body at the lower part of the rotating plate is attached to a concave surface at the upper part of the longitudinal translation plate to form a pair of rotating friction surfaces so as to bear the rotation of the support in a horizontal plane; the longitudinal translation plate, the longitudinal friction cylinder and the bidirectional translation plate are overlapped to form two pairs of sliding friction surfaces so as to bear the translation of the support along the horizontal longitudinal direction; the bidirectional translation plate, the transverse friction column body and the fixing plate are overlapped to form two pairs of sliding friction surfaces so as to bear translation of the support in the horizontal transverse direction. Compared with the prior art, the horizontal deformation of the support is decomposed into translation and rotation in the two vertical directions in the plane, the friction surfaces in the two horizontal directions can be designed respectively, so that different requirements of mechanical properties in the two directions are met, and meanwhile, the energy dissipation capacity of the support under the action of earthquakes and the like is improved.
