[0004] The above-mentioned scheme still has the following disadvantages: when the hoist is used for high-altitude transmission of electrical equipment, the rope ring may fall off from the lifting hook due to wind force and other factors, thereby causing accidents. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a hoist for electrical equipment repair to solve the problem that the hoist may cause accidents when the hoist is used for high-altitude transmission of electrical equipment because the rope ring may fall off from the lifting hook due to wind force and other factors.

[0006] In order to achieve the above-mentioned utility model purposes, the utility model adopts the following technical scheme: a hoist for electrical equipment repair, comprising a connecting ring, a hook is fixed to the bottom surface of the connecting ring, two rotating shafts are formed on the two sides of the hook, a baffle is rotatably arranged between the two rotating shafts, a sub buckle is fixed to the bottom surface of the baffle, a female buckle is formed at one end of the hook, and the sub buckle is inserted into the female buckle.

[0007] Preferably, a lifting rope is arranged on the top surface of the connecting ring, an electric winch is connected to the other end of the lifting rope, and a base is fixed to the bottom surface of the electric winch.

[0008] Preferably, the top surface of the base is provided with an electric rotating groove, a hydraulic push rod is rotatably arranged in the electric rotating groove, and a rotating ring is arranged on the peripheral wall surface of the hydraulic push rod and slidably arranged in the electric rotating groove.

[0009] Preferably, a hanging arm is fixed to the telescopic end of the hydraulic push rod, two rope grooves are formed in the top surface of the hanging arm, pulleys are rotatably arranged in the rope grooves, a hanging rope penetrates through the two pulleys, and a limiting plate is fixed to the top surface of one of the rope grooves.

[0010] Preferably, rotating holes are formed in the two sides of the hanging arm, a fixing block is arranged between the two rotating holes, and the fixing block is connected with the peripheral wall surface of the hydraulic push rod.

[0011] Preferably, a control panel is arranged on the left side of the base, and the electric winch, the electric rotating groove, the hydraulic push rod and the control panel are electrically connected.

[0012] Compared with the prior art, the lifting device for repairing electrical equipment has the following beneficial effects:

[0013] I. In use, the worker first starts the electric winch through the control panel to make the hanging rope move downward, and the hook moves downward along with the movement of the hanging rope. When the hook moves to a height at which the worker can perform the hooking operation, the electric winch is stopped at this time. Then the worker first rotates the baffle upward, then places the rope ring on the electrical equipment on the hook, and then rotates the baffle downward to make the male buckle and the female buckle be inserted, so as to close the baffle and the hook. At this time, the worker starts the electric winch through the control panel to make the hanging rope move upward, and the hook moves upward along with the movement of the hanging rope, so as to lift the electrical equipment. When the electrical equipment is completely lifted off the ground, the worker stops the electric winch. Then the worker starts the hydraulic push rod through the control panel, and under the pushing of the hydraulic push rod, the hanging arm starts to rotate upward, so as to move the electrical equipment to a suitable height to prevent the electrical equipment from being affected due to too low height during high-altitude transportation. During high-altitude transportation of the electrical equipment, due to the action of wind force and inertia, the electrical equipment will sway in the air, so as to drive the rope to sway, which will make the rope ring slide on the hook. Since the baffle is closed with the hook, the rope ring will not fall off the hook due to the resistance of the baffle, which greatly improves the safety of the device.

[0014] II. In use, the worker can control the electric rotating groove through the control panel, so as to rotate the hoisted electrical equipment to the equipment maintenance area, and the hydraulic push rod is arranged to be rotatable, so that the hoisting range of the device is improved. The hydraulic push rod and the rotatable lifting arm are arranged, so that the lifting arm can hoist the electrical equipment of different heights, thereby improving the applicability of the device. Since the top surface of the rope groove is fixed with a limiting plate, when the equipment works in a situation with large wind force, the lifting rope will not fall off the pulley due to large shaking, thereby improving the safety of the device.

The hydraulic push rod 11 and the rotatable lifting arm 13 are arranged, so that the lifting arm 13 can lift electrical equipment of different heights, thereby improving the applicability of the device. Since the top surface of the rope groove 14 is fixed with the limiting plate 18, when the equipment works in a situation with large wind force, the lifting rope 7 will not fall off the pulley 15 due to large amplitude swinging, thereby improving the safety of the device.
