Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the utility model.

It should be noted that, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a removable connection, and an integrally formed structure. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

When the transformer substation is assembled with power equipment, the influence of power failure on power utilization customers is reduced in order to avoid large-area power failure caused by the use of a crane and reduce operation and maintenance cost. The existing construction site adopts a small driving lever hanger and a small crane.

The small deflector rod hanger is generally hoisted by using two equal-diameter steel frames with the same length at the hoisted equipment to be supported in a cross mode or using a high-strength insulating component as a support. The operation range is large, and the pulling rod is easy to topple; the rope must be fixed firmly or pulled by more than two persons, and the safety of the peripheral live interval or the operation process is difficult to ensure.

The principle of the small crane is similar to that of a crane, the largest characteristic is that the crane is flexible to use, and the crane arm can rotate 360 degrees to transfer equipment; however, when the suspension arm rotates, the safety distance of the surrounding electrified interval cannot be guaranteed, the base is poor in fixing stability, and the suspension arm is prone to toppling.

Multiple practical uses show that the small deflector rod hanger and the small crane can temporarily replace a large crane to carry out hoisting operation, the hoisting equipment still has high assembly difficulty and needs to occupy excessive operation space during hoisting operation, and the power failure range cannot meet the target value easily
