Unloading method for UHV transformer body

Abstract

The invention relates to a technology for unloading and positioning a large electric equipment body, in particular to a method for unloading and positioning a UHV transformer body, which adopts a "Tian"-shaped road wooden pier as a support transfer, and lifts the four ends of the transformer through a hydraulic oil pump. Transfer the transformer from the flat car to the wooden pier, adjust the height of the transformer from the ground, and finally merge the transformer into the designated position through the steel rail. Combined with precise operation data, the present invention makes the "Tian"-shaped road wooden pier used stable, safe and reliable. During the process of unloading and putting in place, the lifting point and apex position are reasonably selected to ensure that the equipment will not be deformed under force, and When hoisting the transformer, protect it with pads in time to prevent objects from swimming or toppling due to crane failure and ensure the safety of the equipment; it can ensure that the transformer remains stable without shaking or impacting, and the three-dimensional impact force on the transformer is not greater than 3g. requirements, the process is simple, time-saving and labor-saving, convenient and simple.

Description

technical field [0001] The invention relates to a technique for unloading and placing a large electric equipment body, in particular to a method for unloading and placing a UHV transformer body. Background technique [0002] In electric power construction, the 1000kV transformer has the characteristics of large capacity, large volume, and difficulty in transportation and unloading. Its weight generally exceeds 350 tons, and its volume is more than 115cm×51cm×49.70cm, and the unloading must meet relatively strict impact Requirements and migration standards, that is, in the upper and lower pier projects, strictly control each operation link, so that the three-dimensional impact force on the transformer is not greater than 3g during the whole process, and the vertical and horizontal centerlines of the transformer are aligned with the designated positions, and the error is within the specified range . [0003] In the prior art, the traditional crane method is usually used to un...

Problems solved by technology

[0008] However, the above-mentioned traditional crane placement is difficult to meet the impact requirements and migration standards of UHV transformer unloading and placement. Before unloading and placement, the placement plan must be carefully prepared, including the selection of transportation equipment, construction organization plan, and construction technology. Compilation and review of schemes and safety construction schemes are complex, involving many personnel and equipment, technically difficult, time-consuming and labor-intensive
