Description

Technical Field

[0001] The utility model relates to the technical field of workbenches, in particular to a maintenance platform. Background Art

[0002] Mechanical and electrical equipment in coal mines, such as water pumps, hydraulic presses, lighting equipment, etc., are subject to different degrees of vibration and impact due to the harsh working environment, causing wear or failure of the equipment. In addition, due to the presence of a large amount of dust and even corrosive gases in the surrounding environment, failures often occur. Failure to maintain these mechanical and electrical equipment in a timely manner will affect the normal production of coal mines, and in serious cases may even threaten the personal health or life safety of underground workers. In order to ensure safe production in coal mines, underground mechanical and electrical equipment needs to be repaired and maintained regularly.

[0003] Existing maintenance platforms usually have a turntable to facilitate the adjustment of the angle of electromechanical equipment and reduce the labor intensity of maintenance workers in moving equipment. For example, the utility model patent CN218802076U provides a maintenance platform that uses the output shaft of the drive motor to drive the turntable to rotate through the drive gear and the toothed ring to achieve the function of adjusting the angle of the workpiece to be repaired. Although this maintenance platform reduces the labor intensity of maintenance workers when adjusting the angle of electromechanical equipment, it is still necessary to move the equipment to the maintenance platform by manpower first. Maintenance workers are prone to fatigue, and there is a risk of breaking equipment and getting injured. In addition, this maintenance platform uses the cooperation of the drive motor and the gear meshing structure to adjust the angle of the electromechanical equipment to be repaired. The rotation speed is slow, the adjustment is not flexible enough, and it can only be adjusted in one direction. When it rotates too far, it needs to rotate another circle to adjust it back to the specified position. Utility Model Content

[0008] Furthermore, an oblique support rod is provided between the rotating column and the cross rod, and the oblique support rod can support the cross rod to improve the structural firmness of the device.

[0009] Furthermore, a handle is installed on the rotating column, and the rotation of the rotating shaft can be achieved by rotating the handle.

[0010] Furthermore, when the rotating column rotates, the hook passes over the workbench.

[0011] Furthermore, a bearing platform is fixed on the upper surface of the magnetic metal ring.

[0012] Furthermore, the turntable, the magnetic metal ring and the bearing platform are concentrically arranged.

[0013] Furthermore, there are two telescopic rods, which are respectively mounted on two sides of the mounting base, and the spring is located between the two telescopic rods.

[0014] Furthermore, a universal wheel is installed at the bottom of the base plate, and the universal wheel includes a steering mechanism. A locking roller is fixed to the bottom end of the steering mechanism, which can facilitate the user to move the device, and the locking roller can limit the position of the device.

[0015] The beneficial effects of the utility model are:

[0025] The working principle of the utility model is:

[0026] When the user needs to use this maintenance platform to repair heavier equipment, the user can first use a rope to tie up the equipment to be repaired, and then open the winch mechanism 6 to make the winch mechanism 6 release the cable 8. At this time, the cable 8 slides along the guide pulley 7 to lower the hook 9 to a specified height. The user can hang the hook 9 on the binding rope of the equipment to be repaired, and then use the winch mechanism 6 to lift the equipment to a level above the workbench 10. Then, rotate the rotating column 4 by the handle to rotate the equipment to be repaired to just above the workbench 10, and then operate the winch mechanism 6 to lower the equipment, and then the equipment can be moved to the load-bearing platform 13. The electromagnet 18 is electrically connected to the switch 15. When the user repairs the equipment on the supporting platform 13, the user can press the switch 15. At this time, the switch 15 energizes the electromagnet 18. After being energized, the electromagnet 18 generates magnetism and adsorbs the magnetic metal ring 12. Under the limit of the telescopic rod 16, the supporting platform 13 is prevented from rotating. When the user needs to rotate the equipment, the switch 15 can be pressed again. At this time, the electromagnet 18 is powered off and loses its magnetism, and rebounds and resets under the pulling force of the spring 17. At this time, the supporting platform 13 can be rotated by the turntable 11. The user can manually rotate the turntable 11 to the specified angle and then press the switch 15 to position the equipment angle.
