[0002] As is well known, due to the long-term exposure of electromechanical equipment in coal mines to coal ash, the failure rate and maintenance frequency are relatively high, and regular maintenance is often required; to improve the maintenance convenience of electromechanical equipment, a maintenance platform is mostly used as an auxiliary maintenance tool to maintain and repair electromechanical equipment.

[0003] For example, a Chinese utility model patent discloses an electromechanical equipment maintenance platform (publication (announcement) number CN215735198U), which supports the power-saving equipment by setting a pedestal that can move up and down. The pedestal is connected to the connecting rope of the pedestal through the hook of the electric hoist to lift the pedestal between two guide rails to achieve maintenance states at different heights; when it is necessary to hold and rotate the electromechanical equipment by an angle for maintenance, the pedestal is raised to contact the bottom ends of the left U-shaped clamp and the right U-shaped clamp. Due to the existence of the convex platform, the electromechanical equipment is placed on the convex platform, and the clamping part of the electromechanical equipment is located at the openings of the left U-shaped clamp and the right U-shaped clamp. The left U-shaped clamp is pushed to the right by starting the clamping cylinder so that the left U-shaped clamp and the right U-shaped clamp clamp the clamping part of the electromechanical equipment, and the electromechanical equipment is rotated and adjusted by starting the servo motor, so as to adapt to the all-round maintenance of the electromechanical equipment; and the gantry is provided with brake casters, so that the whole can be moved, with strong flexibility.

[0004] However, due to the heavy weight of the electromechanical equipment and the hoisting mechanism being located above the pedestal, it is inconvenient to pick up and place the electromechanical equipment at the pedestal, and even causes bumps to the electromechanical equipment, with certain limitations in use. Content of the Utility Model

The hoisting frame is provided with a sliding hole allowing the sliding rod to pass through. One end of the sliding rod passes through from the sliding hole, and the other end of the sliding rod is hinged to the screw rod; further, the hoisting frame is a trapezoidal frame; a hand crank is fixedly installed at the end of the screw rod.

[0007] Preferably, the lifting frame includes a beam frame, two telescopic arms and a connecting frame. The two telescopic arms are symmetrically arranged on both sides of the beam frame.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] As described in the background technology, an electromechanical equipment maintenance platform; because the electromechanical equipment is heavy, the lifting mechanism is located above the platform, which is inconvenient when taking and placing the electromechanical equipment on the platform, and may even cause the electromechanical equipment to bump, and has certain usage limitations.

[0022] In order to solve this technical problem, the utility model provides a coal mine electromechanical maintenance auxiliary equipment, which is applied to the auxiliary maintenance of electromechanical equipment.

[0023] Specifically, please refer to Figures 1-3 The coal mine electromechanical maintenance auxiliary equipment specifically includes: a base frame, a maintenance platform fixedly installed in the middle of the base frame, a hoisting frame rotatably installed on the upper part of the base frame, and a driving member providing power for the rotation of the hoisting frame. An electric hoist 1 is installed on the hoisting frame away from the center of the base frame. The driving member includes a slide bar 2, a threaded tube 3 rotatably installed on the base frame, and a screw 4 screwed in the threaded tube 3. A slide hole 5 is provided on the hoisting frame to allow the slide bar 2 to pass through. One end of the slide bar 2 passes through the slide hole 5, and the other end of the slide bar 2 is hinged to the screw 4; further, the hoisting frame is a ladder frame; a hand crank is fixedly installed on the end of the screw 4.

[0024] The utility model provides a coal mine electromechanical maintenance auxiliary equipment. In the initial state, the electric hoist 1 is located at a side away from the maintenance platform. The electric hoist 1 lifts the electromechanical equipment to be repaired.
