Problems solved by technology

First, in electric power construction, there are often problems such as dense equipment structures, dense wiring, etc., and cranes cannot enter and hoist. Generally, human hinges are used for hoisting. The operation of human hinges is complicated and requires the cooperation of multiple people. Not only labor-intensive Large, time-consuming and labor-intensive, long lifting and power outage time, at the same time, there are certain safety risks in the operation; second, even if the crane or other lifting equipment can enter the construction site, it often needs to rely on large-scale power outages to ensure the safety of the construction The safe distance will affect the normal power supply; third, because the rental fee of the lifting equipment is calculated on time, the cost is relatively high
In mountainous areas and areas with poor economic conditions, it is often difficult to install transformers, circuit breakers and other large-scale equipment on the platform. Accident; In CN201040693Y, disclose a kind of household weight hoist, it is characterized in that frame is made of vertical frame, horizontal support, small vertical frame and steel bar slideway, is provided with fixed pulley and movable fixed pulley respectively on it, control One end of the wire is tied to the tether ring, the other end is tied to the hook of the control line through the fixed pulley and the fixed pulley, one end of the wire rope is tied to the wire rope tie plate, and the other end is fixed on On the winch, pull the control line to move the movable pulley and hook to the outside of the window. After the heavy object is lifted in place, the heavy object will be automatically moved into the balcony or indoor under the action of the fixed pulley and wire rope. In addition, a handle can be installed on the transmission shaft. , just by hand, but it is not labor-saving enough, and the motor is too large and needs enough electric energy, which is not conducive to field use; a pulley type manhole cover lifting tool is disclosed in 202054546U; it belongs to a lifting tool; it consists of a base part, a supporting part and The lifting part consists of three parts; the base part includes two parallel base support rods and a support rod connected at both ends of the two parallel base support rods
The support part is composed of a support pole with a boss, a rotatable sleeve set on the support pole, a telescopic support rod I and a telescopic support rod II; the lifting part includes a movable pulley, two fixed pulleys and a hand-operated Wire winding device; a hinge is fixed on the movable pulley, and the hinge is connected with a hook for hooking the manhole cover; although it has a good lifting effect, it is relatively laborious, so a micro-power electric equipment rotary lifting device is needed
