Hoisting equipment for transformer installation

Abstract

The invention provides hoisting equipment for transformer installation. The hoisting equipment for transformer installation comprises a hoisting plate, a hook, a connecting hook, a transformer and a fixed bottom plate, wherein a hook limiting groove is formed in the center of the top of the hoisting plate; the hook is movably connected into the hook limiting groove; a hook bottom plate is fixedlyconnected to the bottom of the hook; ejector rods are fixedly connected to the two sides of the bottom of the hook bottom plate; a strong spring is fixedly connected between the top of the hook bottomplate and the inner top of the hook limiting groove; the connecting hook is connected to the bottom of the hoisting plate in a penetrating mode; push-back device cabins are arranged at the positions,on the two sides of the connecting hook, of the bottom of the hoisting plate; the transformer is connected to the bottom of the connecting hook in a meshed mode; a connecting lock groove is formed atthe meshed part between the top of the transformer and the connecting hook; and the fixed bottom plate is fixedly connected to the bottom of the transformer. According to the hoisting equipment for transformer installation provided by the invention, the problems that in the transformer hoisting process, transformer connection is insufficient due to personnel negligence, transformer bases need tobe arranged by multiple persons in advance for transformer safety, and consequently manpower resources are wasted are solved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a hoisting device for transformer installation. Background technique [0002] In power systems, transformers are often used for step-down voltage, matching impedance, safety isolation, etc. Outdoor transformers are usually hoisted between two columns by mechanical equipment such as cranes, so that the transformer can be kept as horizontal as possible, thereby improving the stability of the transformer. .However, for some areas with excessive slopes or impassable roads such as mountainous areas (also called hills), large machinery such as cranes cannot enter the job site, which limits the application of cranes in transformer hoisting. [0003] In view of the above situation, the general practice in the prior art is to use wood as the cross arm, and then use the cross arm as a support to hoist the transformer to the installation position by using an inverted chain, while ensuring that ...
