Problems solved by technology

[0003] At present, tools such as cranes and chain reversing are used to install transformers in ordinary areas. There are many tools and inconvenient to carry, especially in mountainous areas where cranes are not easy to use, narrow places and installation and disassembly of a single transformer. The cost of using cranes is too high due to terrain restrictions. , using a tripod (inconvenient to transport) and a hand hoist is too much work

Abstract

The invention discloses a simple transformer hoisting device, and relates to the technical field of installation of electric equipment. The device comprises a fixed pulley and a winch, wherein the fixedly pulley is in rotary connection with the upper portion of a pole through a hoop, a horizontal rotary arm is disposed under the fixed pulley, the rotary arm is fixed to the pole through a hoop, and a steel wire rope of the winch winds from the free end of the fixed pulley and the free end of the rotary arm. The simple transformer hoisting device has the advantages of reducing manpower and materials and being suitable for installation of a transformer of various terrains, safe and quick and low in cost, and tools which are used are convenient to transport.

Description

technical field [0001] The invention relates to the technical field of electrical equipment installation, in particular to a simple hoisting device for a transformer. 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. [0003] At present, tools such as cranes and chain reversing are used to install transformers in ordinary areas. There are many tools and it is inconvenient to carry, especially in mountainous areas where cranes are not easy to use, narrow places and the installation and disassembly of a single transformer. The cost of using cranes is too high due to terrain restrictions. , using a tripod (inconvenient to transport) and a hand hoist is too much work. Contents of th...
