Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described:

[0017] Such as figure 1 figure 2 image 3 and Figure 4 The transformer hoisting method shown includes a transformer 1, a crane and a steel wire rope 2 for lifting the transformer 1, wherein in the horizontal and vertical directions of the transformer 1, an inverted chain is provided, and the steel wire rope 2 and the inverted chain are used to move horizontally and vertically. For retracting and unwinding in the vertical direction, put the transformer 1 into the transformer room, and continue to use the reverse chain to move the transformer 1 to the installation position.

[0018] In this embodiment, there are three sets of the inverted chains, wherein one end of the No. 1 inverted chain 5 is fixed at 100 mm on the wall surface of the transformer room, the other end is connected to the side of the transformer 1, and the No. 2 inverted chain 3 and the No. 3 inverted c...

Abstract

The invention provides a transformer lifting method by which manpower and materials can be reduced, time is shortened and high security is ensured. The method is realized by utilizing a large transformer, and a crane and a steel wire rope which are used to lift the transformer, wherein a lifting hook is arranged on the crane. The method is characterized in that the steel wire rope and a chain block are used to reel and release in both horizontal and vertical directions of the transformer so as to place the transformer into a transformer room, and then the chain block is continuously used to move the transformer to the installation position. By adopting the method provided by the invention, the manpower and materials can be reduced, the time can be shortened and the security is high; and meanwhile, the difficulty of large size and heavy weight in the transformer lifting process can be solved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment installation, and in particular relates to a transformer hoisting method. Background technique [0002] In the electrical equipment installation project, transformer installation is an indispensable content. Due to the large size and heavy weight of the transformer, transformer hoisting is often regarded as a key point of electrical equipment installation, which requires sufficient personnel and a long time to complete. Therefore, we conduct research on transformer hoisting methods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transformer hoisting method with reduced labor and materials, short time and high safety in view of the above technical deficiencies. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a transformer hoisting method, including a t...
