Abstract

The invention relates to a portable transformer lifting device which comprises a fixing assembly (2), a lifting arm (3) and a walking trolley (61).The fixing assembly (2) comprises an upper hold hoop assembly (21) and a lower hold hoop assembly (22), the lifting arm (3) is welded to the lower hold hoop assembly (22), a hanging lug opening (32) is formed in the top end of the lifting arm (3), one end of a diagonal stay rope (41) is fixed to the hanging lug opening (32), and the other end of the diagonal stay rope (41) is fixed to the upper hold hoop assembly (21); an amplitude changing assembly (5) comprising the walking trolley (61) is installed on the lifting arm (3), a steering assembly (7) is installed below the lower hold hoop assembly (22), the lifting arm (3) is further provided with a balance arm assembly (8) provided with a weight box (84).The invention aims at solving the technical problem of providing a device which is convenient to assemble and install, light in weight, universal in part, capable of integrating the steering protection function and the lifting overweight alarming function into a whole and capable of ensuring equipment to be safe and reliable during the working process, increasing the equipment use rate and widening the use range.

Description

technical field [0001] The invention relates to the field of electric power construction tools, in particular to a portable transformer hoisting device. Background technique [0002] In electric power construction or maintenance, it is often necessary to install transformers. In general, transformers are hoisted by cranes. However, sometimes transformers need to be installed in remote areas where cranes cannot enter. At the same time, many of the tools that need to be carried during construction have special functions, and a large number of similar tools need to be carried. Bring a lot of unnecessary troubles to equipment installation. [0003] Chinese patent application publication number CN103274311A discloses a transformer rotary boom on a column. The invention discloses a transformer rotary boom on a column. It includes a telescopic boom, a hoop and a boom transmission mechanism, and the hoop is fixed on On the electric pole, the transmission mechanism of the boom incl...
