 Step 3: Lifting the main body of the device by using the lifting device, after the axis transport vehicle is withdrawn, the hydraulic power moving trolley enters the lower part of the device through the track, and fixes the main body of the device on the frame of the hydraulic power moving trolley;

Step 4: The hydraulic power moving trolley moves the device body to the side of the device base, and lifts the device body through the lifting device. After the lowest point of the device body crosses the foundation, the mobile car enters the basic position, and then the device body is lowered by the lifting device. After the installation accuracy of the main body of the equipment is adjusted, it is installed on the equipment installation saddle. Step 5: Move the mobile trolley out of the equipment installation base position, construct the foundation of the lower part of the equipment body, and complete the final assembly of the equipment. The large-scale industrial and mining equipment is pre-assembled and lifted and moved into position. The lifting device comprises: four columns and four beams disposed at the top of the column, and the lifting device is erected on the beams on both sides.

 The large-scale industrial and mining equipment is pre-assembled and lifted and moved in place. The lifting device has four core-through hydraulic lifting devices, and includes: an independent hydraulic system, a separate core-through hydraulic jack, and an independent wire rope winding. The device and a set of shared PLC remote control boxes.

 The large-scale industrial and mining equipment is pre-assembled and lifted and moved. The four beams on the upper part of the lifting frame are provided with mounting brackets, and the hydraulic lifting device is installed at four corners of the mounting bracket.

 The large-scale industrial and mining equipment pre-assembles and lifts the in-position method, and the mobile trolley comprises: a supporting column and a vehicle body carrying beam on both sides, and the lifting device is mounted on the supporting columns on both sides.

 The invention adopts the pre-installed equipment main body in the factory, and simultaneously performs basic construction and equipment installation preparation work on the equipment installation site, the equipment body and accessories are transported to the site by the mobile equipment, lifting and unloading the vehicle by using the lifting frame, and the moving vehicle exits, the mobile trolley Move the lifting frame below the load, and then move the lifted device out of the frame. After lifting to the predetermined height, the trolley will be moved into the equipment foundation by the lifting device. After the precision is adjusted, the lifting device will fall back and be installed in place by the lifting device. The invention subverts the previous grinding machine installation process, and can pre-assemble large-scale equipment such as a mill in a pre-assembly site in advance, which not only shortens the installation period, but also reduces the on-site installation strength and greatly reduces the installation cost. The complete system is driven by a hydraulic system, which is stable in operation, high in lifting weight, high in height, and capable of high-precision positioning and adjustment. It is a function not available in other installation methods. At the same time, the equipment has low requirements on the installation environment, solves the need for the hoisting of large equipment, and has a short impact time on the surrounding construction environment, which better solves the cross-effects with other special installations.
