The invention provides a jacking screw structure for pre-adjusting the height of a lifting roller, as well as the lifting roller. The jacking screw structure comprises a transmission device comprising a speed reducer, a driving wheel and a driven wheel, and a pair of jacking screw components, wherein each jacking screw component comprises a bracket, a jacking screw, a guiding key, a guiding part and a nut; the jacking screw is provided with an external screw part and a smooth part, and a longitudinally extending keyway is formed in the smooth part, and the jacking screw can move up and down in the bracket; a fixing part is arranged on the guiding key and fixed to the bracket; the guiding part is inserted into the keyway, so that the jacking screw moves along the keyway relative to the guiding key; the nut is supported on the bracket in a rotating manner, a first center through hole is formed in the nut, and an internal screw part corresponding to the external screw part of the jacking screw is arranged in the first center through hole; the nut and the driven wheel are coaxially fixed, and are rotated together. According to the jacking screw structure, the lifting speed and position of a roller frame can be controlled synchronously, and the operation time can be reduced.
Description
technical field [0001] The invention relates to an auxiliary machine of a gantry hydraulic machine-a lifting roller table, and more particularly relates to a jacking screw structure for pre-adjusting the height and position of the lifting roller table. Background technique [0002] The new development trend of the shipbuilding industry puts forward higher requirements for the hull processing equipment. The portal hydraulic press is an essential and important equipment for the bending of steel plates. [0003] As the auxiliary machine of the portal hydraulic press, the lifting roller table is composed of two sections of active roller table, lifting device, roller table frame and so on. The lifting device of the prior art adopts the structure that the jacking cylinder and the jacking screw rod are used together, and the lifting of the roller table is realized by the telescoping of the piston rod of the jacking cylinder. The jacking screw is used for the height position pre-a...
