7) starting a jack I (601) on a convex block (6042) through a controller of a hydraulic pump control system (9), clamping a telescopic end of the jack I (601) into a clamping groove II of a U-shaped plate II (6062), pushing the U-shaped plate II (6062) by the jack I (601), driving a plate III (606) to transversely move on a ball of the plate II (605) by the U-shaped plate II (6062), transversely moving straight arms II on two sides of the plate III (606) in a hole II of the U-shaped plate I (6051), and transversely moving a bearing platform (8) on a hollow column (6061) and a bridge;
8) starting a jack III (603) on a vertical section of an L-shaped plate (6041) through a controller of a hydraulic pump control system (9), clamping a telescopic end of the jack III (603) into a clamping groove I on two sides of a U-shaped plate I (6051), pushing the U-shaped plate I (6051) by the jack III (603), driving a plate II (605) and a plate III (606) to move back and forth on a ball of the plate I (604) by the U-shaped plate I (6051), and then moving a bearing platform (8) on a hollow column (6061) of the plate III (606) and a bridge back and forth along with the plate II (605) and the plate III (606);
9) through the calculation of a hydraulic pump control system, after the vertical position, the horizontal position and the front and back position of the bridge are adjusted to enable the bridge to correspond to the support, the jacking oil cylinder (4) is controlled to contract through the controller, the bridge descends and is arranged on the support, and the installation work is completed.
