Technical Field
[0001] The utility model relates to a lifting tool, in particular to a lifting tool for lifting a large box-shaped cabin body. Background Art
[0002] With the development of new energy technologies such as solar energy and wind energy, energy storage technologies have also developed rapidly; energy storage devices can provide various services for power grid operation, such as peak shaving, frequency modulation, standby, black start, and demand response support, and are important means to improve the flexibility, economy, and security of the power system; energy storage can significantly improve the consumption level of renewable energy such as wind and light, support distributed power and microgrids, and is a key technology to promote the replacement of the main energy from fossil energy to renewable energy; the energy storage systems involved in existing energy storage power stations adopt a container integrated design scheme, with prefabricated cabins arranged outdoors, and are equipped with one-on-one step-up converter cabins, as well as large box-shaped cabin bodies such as 400-volt prefabricated cabins, 35-kilovolt distribution room prefabricated cabins, SVG prefabricated cabins, grounding transformer and resistor cabinet prefabricated cabins, and secondary equipment prefabricated cabins; during the installation process of large box-shaped cabin bodies, it is necessary to use lifting equipment to lift each equipment cabin body from the transportation machinery to the equipment foundation. Traditional lifting tools generally use steel wire ropes as the main load-bearing cables. The advantages of steel wire rope slings are wear resistance, high temperature resistance, not easy to break, and are suitable for large-tonnage lifting and high-altitude lifting, and the requirements for the use environment are relatively strong. However, steel wire ropes with too thick specifications are not easy to stretch and cannot be used to lift the boxes of flammable, explosive, and precision equipment. Moreover, the steel wire ropes are arranged in an isosceles triangle under the hook, and the included angle is generally very small, which will scrape off the paint film on the surface of the cabin body during the lifting process; how to develop a lifting device that does not damage the paint film on the surface of the cabin body and has a soft and easy-to-stretch sling has become an urgent technical problem to be solved on site.

[0016] The manufacturing and installation process of the lifting tool of the present utility model is as follows:
[0017] First step: Use a section of rectangular square steel to make the square steel lifting beam 3. The length of the square steel lifting beam 3 should be slightly larger than the width of the box-shaped cabin 2. Grind the cut part at the end of the square steel lifting beam 3 to make it flat and burr-free.
[0018] Second step: Use a steel plate with a certain thickness to make the closure plate. The area of the closure plate should be larger than the area of the end of the square steel lifting beam 3. Make the closure plate into a rectangle, and open sling passing holes at the lower left and right corners of the closure plate.
[0019] Third step: Use a steel plate with the same thickness as the closure plate to make the lifting lug plate. Cut the upper two corners of the lifting lug plate into triangles, open a lifting hole in the middle of the upper part of the lifting lug plate, then press the lifting lug plate against the top of the closure plate along the center line of the square steel lifting beam 3, and then weld the side of the lifting lug plate to the closure plate, and weld the bottom of the lifting lug plate to the top section of the square steel lifting beam 3. The lifting lug plates are symmetrically arranged at both ends of the square steel lifting beam 3.
[0020] Fourth step: Equally spaced sling through holes are arranged on the front side beam and the rear side beam of the rectangular frame base 1, and the positions of the sling through holes on the front side beam and the rear side beam should be arranged in pairs.
[0021] Step 5: Select the upper and lower suspension straps according to the masses of the box-shaped cabin 2, the square steel lifting beam 3 and the lifting hook. It is required that the suspension straps be made of high-strength polyester filaments, with soft texture, non-conductive, non-corrosive, light in mass, good in flexibility and easy to bend. Moreover, the suspension straps have a high tensile strength and can be easily distinguished by color to differentiate the upper and lower suspension straps. When the suspension straps lift the box-shaped cabin 2, there should be a certain gap between the suspension straps and the front and rear vertical surfaces of the box-shaped cabin 2.
[0022] Step 6: Select the lifting rings according to the masses of the box-shaped cabin 2, the square steel lifting beam 3, the lifting hook and the suspension straps. The specifications and sizes of the lifting rings should be determined through calculation according to the using parts.
[0023] Step 7: Connect and fix the 4 lower suspension straps to the lifting rings on the sealing plate of the square steel lifting beam 3 through 8 crossbeam lifting rings, and then suspend the upper suspension strap 17 on the lifting hook 4 of the lifting machinery through the lifting rings of the lifting holes on the lifting lug plate. A clamping plate is arranged at the outer opening of the lifting hook 4 to prevent the upper suspension strap from being unhooked.
