[0005] The technical solution of the utility model is: a hoisting device for electric power transmission and transformation engineering construction, comprising a base, a stabilization component, an operating table, an electric wire take-up wheel, a hoisting component, and a limiting component; a stabilization component for maintaining the stability of the hoisting device when lifting the electric power transmission and transformation engineering equipment or accessories is installed in the middle position of the upper end of the base; the upper end of the stabilization component is fixedly connected to the operating table; the upper end of the operating table is installed with an electric wire take-up wheel; a limiting component for limiting the rotation of the wire take-up wheel when the electric wire take-up wheel stops is provided on the side of the electric wire take-up wheel; the lower end of the electric wire take-up wheel sling is fixedly connected to the hoisting component.

[0006] Preferably, in the first step, the base is firmly installed at the required position, such as on a lifting vehicle or the ground, the electric take-up wheel is started, and the retracted and released rope is adjusted so that the lifting assembly can be easily moved to the required position; in the second step, the lifting assembly clamps the power transmission and transformation engineering equipment or accessories, and gradually rises by controlling the electric take-up wheel. When the lifting assembly rises, the stabilization assembly covers the connecting end of the rope and the lifting assembly and rises with it. This can limit the rope from being too long and being affected by external wind force, causing the lifting assembly to swing sharply, causing safety risks such as instability and falling of the equipment and accessories; in the third step, after the power transmission and transformation engineering equipment or accessories rise to a high place, the limiting assembly limits the rotation of the electric take-up wheel when it stops, and adds a layer of insurance to the electric take-up wheel to ensure safe operation.

[0009] Preferably, the limiting component includes a mounting frame, a telescopic cylinder, a limit rod and a limit groove; a telescopic cylinder is installed at the front end of the mounting frame; after the power transmission and transformation engineering equipment or accessories rise to a high place, the limiting component is started, the telescopic cylinder extends the limit rod, and the limit rod passes through the inner side of the limit groove of the electric take-up wheel, so that the rotation of the electric take-up wheel stops, adding a layer of insurance to the electric take-up wheel to ensure safe operation.

[0010] Preferably, the rear end of the telescopic cylinder piston rod is fixedly connected to a limit rod; the outer side of the electric take-up wheel is provided with annular limit grooves distributed equidistantly; the limit rod passes through the inner side of the limit groove.

When the electric take-up wheel stops running, the limiting component can add a layer of insurance to the electric take-up wheel to ensure safe operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 3 In this embodiment, the lifting assembly 5 includes a cross 501, a control gas rod 502, a clamping plate 503, an extension cavity 504 and an elastic positioning block 505; the control gas rod 502 is installed at the front, back, left and right ends of the cross 501; the cross 501 moves to the upper side of the power transmission and transformation engineering equipment or accessories, and the control gas rods 502 in four directions control the clamping plate 503 to clamp the equipment or accessories synchronously from four sides, and can also clamp in both directions.

[0024] See also Figure 4 In this embodiment, the limiting component 6 includes a mounting frame 601, a telescopic cylinder 602, a limit rod 603 and a limit groove 604; the telescopic cylinder 602 is installed at the front end of the mounting frame 601; after the power transmission and transformation engineering equipment or accessories rise to a high place, the limiting component 6 is started, the telescopic cylinder 602 extends the limit rod 603, and the limit rod 603 penetrates the inner side of the limit groove 604 of the electric wire take-up wheel 4, so that the rotation of the electric wire take-up wheel stops, and a layer of insurance is added to the electric wire take-up wheel 4 to ensure safe operation.
