- 1 Preassembly, Lifting, Transport and Positioning Devices for Large Engineering and Mining Machinery Components Technical field [0001] This present invention related to the accurate (± 1mm) placing and positioning of large engineering components and s of machinery, especially related to the specific type of positioning device for large engineering and mining components and machinery s. Background Art [0002] The natural trend is for engineering and mining machinery components becoming larger and heavier. For example, the dimensions of Ball Mills and AG (autogenous) Mills used in the mining industry is generally several meters to even dozens of meters in length and or diameter and the weight frequently exceeds hundreds of tons and now in many cases in excess of a thousand tonnes. If such a machine is assembled and positioned on site, large storage areas for materials and assembly is required, which is not easily managed and in many cases where existing plants have very limited plot sizes, this option is ruled out. The main bodies of large machines are usually preassembled in the factory before being delivered to the site for installation and positioning. If the aforementioned large machines are positioned with cranes, it would be very difficult to lift due to the complex shape, heavy weight, location within the process plant and the lifting cost will also be very high, also the associated exposure to additional risks and hazards with the use of large cranes. [0003] It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative. Summary of the invention [0004] In one aspect, the present invention provides a lifting, moving and positioning device for large engineering components and mining machinery, which effectively and safely solves the problem of lifting, moving and positioning large heavy machinery and components, runs stably, is safer and costs less than cranes. [0005] In one aspect, the present invention provides preassembly, lifting, transport and positioning devices for heavy engineering and mining machinery, including a rail system for precise positioning on a foundation and components for lifting, transporting and positioning the machinery along the rail system, the devices including: -2 a lifting frame with hydraulic lifting devices, the hydraulic lifting devices including four strand jack hydraulically operated lifting devices made up of an independent hydraulic system, independent "strand jack" hydraulic jack an independent cable recoil device and a common PLC remote control box; and a hydraulically powered bogey set including four hydraulically powered bogey trolleys which move along the rail system, the hydraulically powered bogey trolleys being equipped with precision lifting and positioning devices having an integrated system of precision adjusting devices having parallel multi-control hydraulically driven precision adjusting device along with a mechanical winch and screw adjusting device. [0006] In one aspect, provision is made for preassembly, lifting, moving and positioning components for large engineering and mining machinery. It also provides a secure platform and solid guidance system for tracking the s to be placed to an exact predetermined position. This is accomplished with the use of the lifting frame, with a lifting device and hydraulic powered bogey trolleys, including four or more hydraulic powered bogey trolleys which can move back and forth on the track. The hydraulic powered bogey trolleys are equipped with the positioning and lifting devices. [0007] In one aspect, the preassembly, lifting, transport and positioning devices for large engineering and mining machinery, the lifting device is made up of four columns and four beams at the top of the columns, said lifting devices are placed on the beams at both sides. [0008] In one aspect, the preassembly, lifting, transport and positioning devices for large engineering and mining machinery, said lifting devices consist of four "strand jack" hydraulic lifting devices including an independent hydraulic pumping system, independent "strand jack" hydraulic jacks, an independent strand coiling device and a common PLC remote control box. [0009] In one aspect, the preassembly, lifting, transport and positioning devices for large engineering and mining machinery, the primary installation frame is set up on the said four beams on the primary lifting frame. The hydraulic lifting devices are installed at the four corners of the primary installation frame. [0010] In one aspect, the preassembly, lifting, transport and positioning devices for large engineering and mining machinery, said bogey trolleys include the carrying columns at both sides and the beams carrying the bogey trolleys, said lifting devices are set up on the carrying columns at both sides.

[0012] In one aspect, the preassembly, lifting, transport and positioning devices for large engineering and mining machinery, said hydraulic powered bogey trolleys include precision adjusting devices, which incorporates an in parallel multi-control hydraulic cylinder precision adjusting device with a mechanical winch and screw adjusting device. [0013] The benefit of the present invention is that the machinery component/ to be lifted is preassembled in the factory while the foundation construction and preparation for machine installation are performed at the construction site. The whole assembled machinery/ component body and accessories are transported to the site and lifted and unloaded with lifting frame. After the transportation vehicle leaves, the bogey trolleys roll under the lifting frame to carry the machine. After the machine is lifted to the preset height, the bogey trolleys will be placed onto the machine foundation by the lifting devices. After the precision adjustment, the lifting devices will drop down and the lifted machine is installed and positioned. The present invention supplants the traditional installation methods for grinding mills of all sizes. Large machines such as grinding mills can be preassembled at the manufacturer's facility, which not only shortens the installation period but also reduces the field installation work and greatly reduces the installation cost and is safer. The whole system is driven by the hydraulics. It can run stably, lift heavy loads to elevated positions and adjust the positions with high degree of precision, which cannot be achieved with other more traditional installation methods. The operation of the machine has a low impact on the installation environment, which solves the problem of requiring a large plot area for placing of large machinery and components. The effect on the surrounding environment is short, which avoids the interface issues with the other special installations and construction programme.
