3. The present invention uses two fixed pulleys to lift small equipment. The equipment can be lifted to the required height at any angle, and then accurately positioned by turning the handle, and the lightning arrester, current transformer CT, and voltage transformer weighing about 100KG can be replaced reliably. Small equipment such as PT can improve the flexibility and adaptability of construction.

4. The present invention can effectively reduce potential safety hazards in the equipment maintenance process, and avoid large-scale and long-term power outages on surrounding users when large-scale construction machinery cannot enter the work area, thereby ensuring orderly construction.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Numbers in the figure: 1 cement rod bracket; 8 rotating handle; 9 small electric equipment; 10 hanging ring; 11 base.

Detailed ways

Referring to Fig. 1, in this embodiment, a detachable bracket applied to lifting of small electric equipment is vertically arranged on one side of the cement pole support 1 of the electric equipment, and is composed of a vertical pole 2 and a pole welded on the top of the vertical pole 2 The inverted L-shaped support formed by the crossbeam 3 can be made of alloy material, and a hanging ring 10 is arranged at the center of the crossbeam 3, and the top fixed pulley 5 is suspended by the hanging ring 10; the vertical rod 2 is It is fixed on one side of the cement pole bracket 1 through a "U" type hoop and can rotate in the "U" type hoop; the bottom of the pole 2 is padded with a backing plate 7, which can ensure the free rotation of the pole 2 and the inverted L-shaped bracket A bottom fixed pulley 6 is fixed by a steel wire rope at the lower part of the cement rod support 1, and the downward pulling force is changed to a horizontal pulling force through the bottom fixed pulley 6, which can reduce the scope of work to meet the needs of manpower construction, thereby ensuring sufficient Safety distance, the rope that is connected to small electrical equipment 9 walks around top fixed pulley 5 and bottom fixed pulley 6 successively.

In order to increase the contact area with the ground and play a heavy role, and at the same time reduce the friction force when the inverted L-shaped bracket rotates, a backing plate 7 is provided at the bottom of the vertical pole 2. In specific implementation, the backing plate 7 can be 300×300 steel plate.

A rotating handle 8 is also provided below the vertical rod 2, and the vertical rod 2 can freely rotate by using the rotating handle 8 in the metal ring connected with the "U" type upper hoop.
