[0040] Working principle:

[0041] This application includes an electric control device, a power transmission device and an angle steel fixing fixture; the electric control device is the energy unit of the entire electric winch, providing energy for the electric winch, powered by a lithium battery 16, greatly reducing the volume and weight of the battery; at the same time, it is also the operation control center of the whole set of devices, and in addition, a handheld remote control is configured, which is also used for control operations. Its structural functions include: a power switch button 9, a rising button 10, a falling button 11, which control the power transmission device to switch to the rising or falling mode; a stepless speed regulation handle 4, which can adjust the rotation speed of the rotating motor 21 according to the amplitude of the handle rotation, controlling the rising or falling speed of the power transmission device; a power display screen 8, clicking the power switch button 9, the power display screen 8 can display the current battery power, and at the same time, it starts to flash when the power is lower than 10% power, reminding the personnel during work that the remaining battery power is insufficient, facilitating on-site work arrangements and timely battery replacement; a carrying handle 3, facilitating personnel handling; an emergency stop button 12, which can immediately stop the moving power transmission device in case of an emergency, playing a protection function and making the whole set of devices safer; a battery compartment, the compartment opening adopts a movable design, opening the compartment door to install and replace the lithium battery 16, and closing and locking it after replacement; heat dissipation holes 25, dissipating heat from the battery, avoiding combustion or explosion of the battery caused by high temperature, playing a protective role;

[0042] The power transmission device is the power unit of the entire electric winch, converting electrical energy into kinetic energy, outputting strong power, driving the rope wound around the grinding disc, lifting or lowering heavy objects, and finally achieving the transmission and traction of heavy objects. The angle steel 35 is a part of the tower structure, with a stable and reliable structure, thus ensuring the stability and reliability of the power transmission device during operation; the heat dissipation fan 26 cooperates with the heat dissipation holes 25 on the housing 2 to improve the heat dissipation efficiency inside the power transmission device, with better heat dissipation effect, preventing the rotating motor 21 from overheating, protecting the rotating motor 21 and increasing its service life; a brake 22, used for deceleration and emergency braking;

[0043] The angle steel clamp 6 is the fixing component of the entire electric winch, fixing the power transmission device on the angle steel of the pole tower, and includes a first angle steel clamp fixing seat 27, a second angle steel clamp fixing seat 28, an angle adjustment disc 31, an electric winch main body seat 32, and a plunger screw 33. The angle adjustment disc 31 can adjust the fixing angle of the electric winch relative to the angle steel through the rotating shaft 30 to achieve an angle fit with the angle steel 35, ensuring that the winch disc 20 does not tilt, resulting in extrusion of the rope on the winch disc 20 during operation. The first angle steel clamp fixing seat 27 and the second angle steel clamp fixing seat 28 cooperate with the locking component, can adapt to clamp angle steels of various specifications and models, and fit closely with the angle steel 36. The angle steel fixing seat is firmly connected to the angle steel 36 through the locking piece, and the angle steel fixing seat engages with the ratchet teeth on the locking component to prevent the meshing block from slipping, resulting in insecure connection with the angle steel, and the contact is more firm; tighten the nut on the locking piece, and the angle steel clamp is firmly connected to the angle steel.
