The invention also discloses a using method of the preventive maintenance system of the electromechanical equipment, which is characterized by comprising the following steps:
S1, when machine tool equipment drives a control box 2 to vibrate for a long time to loosen anchor ear screws during working, the control box 2 slides downwards along an upright post 1, when a positioning plate 4 at the bottom of the control box 2 abuts against a fixed seat 3, a fixed block 301 is inserted into a slot 401, and a first spring 501 presses a clamping block 5 into a clamping groove 302 on the side wall of the fixed block 301, so that the falling control box 2 can be supported and fixed;
S2, when the control box 2 slides down because of loosening of screws, the positioning plate 4 at the bottom of the control box also drives the fixed rod 10 to slide down, at the moment, the fixed rod 10 drives the rotating shaft 801 and the gear 802 on the supporting plate 7 to rotate through the toothed plate 11 at the bottom of the fixed rod, so that the movable column 8 on the supporting plate 7 can be driven to turn upwards, and after the control box 2 abuts against the fixed seat 3, the turned movable column 8 just drives the fixed head 9 to abut against two sides of the control box 2, so that two sides of the control box 2 are clamped and fixed;
S3, when the control box 2 slides downwards, the control box 2 is contacted with each cleaning barrel 1701 on the support 17, the cleaning barrels 1701 are extruded by the control box 2 and move towards the outer side of the fixed barrel 15 through the sliding rods 16, at the moment, the cleaning barrels 1701 roll against the outer wall of the control box 2, after the control box 2 is abutted against the fixed base 3, the cleaning barrels 1701 are attached to the front side surface of the control box 2, so that dust on the surface of the control box 2 can be cleaned, and the front side of the control box 2 can be extruded and fixed by the aid of the springs III 1501;
S4, after the control box 2 slides downwards, the lifting rope 1401 wound on the reel 14 can be pulled, at the moment, the lifting rope 1401 can pull the reel 14 and the rotating rod 13 to rotate, and the torsion spring 1301 has resistance for preventing the rotating rod 13 and the reel 14 from rotating, so that the falling control box 2 can be pulled and buffered, and the control box 2 can slowly slide downwards and be in contact with the fixed seat 3;
S5, after the control box 2 slides downwards to be in contact with the fixed seat 3, the fixed rod 10 and the toothed plate 11 at the bottom of the control box can drive the compression bar 1101 to move downwards to just press the switch 1901 on the connecting plate 1801, so that the alarm 19 can be started to work to give out an alarm sound to remind workers that the control box 2 slides down due to loosening of hoop screws.
The above embodiments are only for illustrating the present invention and not for limiting the technical solutions described in the present invention, and although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and thus any modifications or equivalent substitutions are made thereto, and all technical solutions and modifications thereof without departing from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
