Description

Technical Field

[0001] The utility model belongs to the technical field of combined pulleys, in particular to a combined pulley for non-stop maintenance of power transmission and distribution. Background Art

[0002] Transmission and distribution: Transmission refers to the transmission of electric energy. Through transmission, power plants and load centers that are far apart are connected, so that the development and utilization of electric energy can transcend geographical limitations; transformation refers to the process of using certain equipment to change the voltage from a low level to a high level (boosting) or from a high level to a low energy level. Distribution is the means of distributing electricity to users in the area where electricity is consumed, directly serving users. The existing transmission and distribution will use corresponding combined pulleys for lifting or lowering transportation during non-stop maintenance. The combined pulley body is rotatably installed on the inside of the shell with bolts. Each disassembly and assembly requires the removal of multiple bolts in sequence for replacement and maintenance. The operation is cumbersome and complicated, so it needs to be improved.
