Abstract
The invention relates to a screw drill mounting and dismounting support for accurately centering, which is used for dismounting large revolving body spare parts in the industries of petroligenic natural gas, coal mines and urban construction. The support can solve the problem of assembly defectives caused by inaccurate centering of fixing pliers and clamping pliers of a six-cylinder hydraulic system in the prior art. The support adopts the technical scheme that working rails are arranged on the ground; two stator trolleys are mounted on one rail; rapid make-up pliers, a rotor trolley and a thrust hydraulic cylinder are mounted on the other rail; the thrust hydraulic cylinder is mounted on a thrust hydraulic cylinder rack; fixing pliers, clamping pliers and the rapid make-up pliers are mounted on a fixing pliers working rail; the fixing pliers and the clamping pliers comprise fixing plates, driving plates, claws and driving hydraulic cylinders; the fixing plates are mounted on racks; and fixing plate pins penetrate through slide grooves in the middles of the driving plates to be matched with claw pin holes. The mounting and dismounting support solves the non-centering in a clamping process, reduces the number of the driving hydraulic cylinders and the times of centering adjustment, lowers the cost, and improves the working efficiency.
