Technical Field

[0001] The present invention relates to the technical field of electromechanical maintenance, and in particular to a preventive maintenance system for electromechanical equipment and a method for using the system. Background Art

[0002] Electromechanical equipment generally refers to machinery, electrical appliances and electrical automation equipment; with the continuous improvement of technology, traditional mechanical equipment has entered a new stage of combining machinery and electricity, and its application scope has been continuously expanded. Since the 1960s, computers have gradually become popular in the scientific research, design, production and management of the machinery industry, creating conditions for the machinery manufacturing industry to develop in a more complex and precise direction. Electromechanical equipment has also begun to develop towards digitalization, automation, intelligence and flexibility, and has entered a new stage of modern equipment. Preventive maintenance of equipment refers to maintenance performed in accordance with a predetermined plan or goal in order to maintain the specified functions of the system and prevent system performance degradation. It is usually called advance maintenance.

[0003] The maintenance and management of electromechanical equipment mainly relies on the working cycle of the equipment or the state of direct observation. This method often reacts only when the equipment fails, which has a large lag. At present, the control box is installed on the electromechanical equipment such as machine tools in the factory through the column with the clamp and screws. When the machine tool equipment vibrates during long-term operation, the screws on the control box will loosen, which can easily cause the control box to slide off the column and hit the machine tool. If there are no workers around the machine tool, it will not only damage the equipment, but also easily cause accidents. Summary of the invention

A protective box is provided on the wall of the column rod, and movable grooves for rotating the movable columns are provided on both sides of the protective box.

[0009] As a preferred technical solution of the present application, the transmission assembly includes a fixed rod arranged at the bottom of the positioning plate and extending downward through the fixed seat, a toothed plate arranged at the bottom of the fixed rod, a rotating shaft rotatably arranged between two symmetrical support plates, and a gear arranged on the rod wall of the rotating shaft and meshing with the toothed plate. The movable column is fixedly connected to the rod wall of the rotating shaft, a baffle is provided on the side wall of the support plate, the fixed rod is slidably connected to the baffle, and a spring 2 is sleeved on the rod wall of the fixed rod between the baffle and the toothed plate.

[0010] As a preferred technical solution of the present application, the fixed head includes an arc-shaped clamp 1 arranged on the top of the movable column, two groups of arc-shaped clamps symmetrically slidably arranged on both sides of the arc-shaped clamp 1, and two groups of arc-shaped clamps symmetrically slidably arranged on both sides of the arc-shaped clamp 2.

[0014] The present invention also discloses a method for using a preventive maintenance system for electromechanical equipment, comprising the following steps: S1: When the machine tool equipment drives the control box to vibrate for a long time during operation, causing the clamp screws to loosen, the control box will slide down along the column. When the positioning plate at the bottom of the control box contacts the fixing seat, the fixing block will be inserted into the slot. At this time, the spring will squeeze the block into the slot on the side wall of the fixing block, thereby supporting and fixing the falling control box. S2: When the control box slides down due to the loosening of the screws, the positioning plate at the bottom will also drive the fixing rod to slide down. At this time, the fixing rod will drive the rotating shaft and gear on the support plate to rotate through the tooth plate at the bottom, and then drive the movable column on the support plate to flip upward. When the control box is against the fixing seat, the flipped movable column will just drive the fixing head to contact the two sides of the control box, clamping and fixing the two sides of the control box; S3: When the control box slides down, it will also contact the cleaning cylinders on the bracket. The cleaning cylinders will be squeezed by the control box and move toward the outside of the fixed cylinders through the slide rods. At this time, the cleaning cylinders will roll along the outer wall of the control box. When the control box and the fixed seat are against each other, the cleaning cylinders will stick to the front surface of the control box, which can not only clean the dust on the surface of the control box, but also squeeze and fix the front side of the control box with the spring three. S4: After the control box slides down, it will pull the rope wrapped around the reel. At this time, the rope will pull the reel and the rotating rod to rotate. The torsion spring will have a resistance to hinder the rotation of the rotating rod and the reel, thereby pulling and buffering the falling control box, allowing the control box to slowly slide down and contact the fixed seat; S5: After the control box slides down and contacts the fixed seat, the fixing rod and the tooth plate at the bottom will drive the pressure rod to move down and squeeze the switch on the connecting plate, thereby activating the alarm to sound an alarm to remind the staff that the control box has slipped due to the loosening of the clamp screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the machine tool equipment drives the control box to vibrate for a long time during operation and causes the clamping screw to loosen, the control box will slide down along the column. When the positioning plate at the bottom of the control box abuts against the fixing seat, through the provided locking assembly, when the fixing block is inserted into the slot, the spring will squeeze the card block into the card slot on the side wall of the fixing block for a while, so that the falling control box can be supported and fixed. When the control box and the fixing seat need to be disassembled, the bolts and pull ropes can be used to first unscrew the bolts from the positioning plate, and then the card block can be pulled back into the slide slot by the pull rope, so that the fixing block can be loosened, and the control box can be pulled out from the fixing seat at this time, which not only can fix the fallen control box, but also can disassemble the control box and the fixing seat, thereby solving the problem in the prior art that the control box slides from a high place and collides with the machine tool equipment due to loose screws; When the control box slides down due to loose screws, the positioning plate at the bottom of the control box will also drive the fixing rod to slide down through the clamping assembly. At this time, the fixing rod will drive the rotating shaft and gear on the support plate to rotate through the toothed plate at the bottom, and then drive the movable column on the support plate to flip upward. When the control box is against the fixing seat, the flipped movable column will just drive the fixing head to abut against the two sides of the control box, clamping and fixing the two sides of the control box to prevent the control box from falling and being damaged due to loose screws. When the control box slides down, it will also contact the cleaning cylinders on the bracket. The cleaning cylinders will be squeezed by the control box and move toward the outside of the fixed cylinders through the sliding rods. At this time, the cleaning cylinders will roll along the outer wall of the control box. When the control box and the fixed seat are against each other, the cleaning cylinders will stick to the front surface of the control box, which can not only clean the dust on the surface of the control box, but also cooperate with the springs to squeeze and fix the front side of the control box. After the control box slides down and contacts the fixed seat, the fixed rod and tooth plate at the bottom will also drive the pressure rod to move down and squeeze the switch on the connecting plate, thereby activating the alarm to sound an alarm to remind the staff that the control box has slipped due to the loosening of the clamping screws, and through the set suspension assembly, the falling control box will pull the lifting rope wrapped around the reel. At this time, the lifting rope will pull the reel and the rotating rod to rotate, and the torsion spring will have a resistance that hinders the rotation of the rotating rod and the reel, thereby pulling and buffering the falling control box, allowing the control box to slide down slowly and contact the fixed seat, avoiding the control box from falling directly and colliding with the fixed seat with a large force and causing damage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0019] like Figures 1 to 6As shown, this embodiment proposes a preventive maintenance system for electromechanical equipment, including a column 1 and a control box 2 installed on the column 1 through a clamp, a fixing seat 3 is provided on the outer wall of the column 1 below the control box 2, a positioning plate 4 is provided at the bottom of the control box 2, a locking assembly is provided between the positioning plate 4 and the fixing seat 3, a clamping assembly for fixing both sides of the falling control box 2 is provided at the bottom of the fixing seat 3, a limiting assembly for blocking the front side of the falling control box 2 is also provided on the clamping assembly, and an alarm assembly is provided on the column 1 which can automatically alarm after the control box 2 falls.

[0020] When the machine tool equipment drives the control box 2 to vibrate for a long time during operation, causing the clamping screws to loosen, the control box 2 will slide down along the column 1. Through the provided locking assembly, the control box 2 that has been sliding down can be locked and fixed when it contacts the fixing seat 3 under the column, thereby preventing the control box 2 from continuing to fall and hit the machine tool, causing damage to the equipment. When the control box 2 falls, through the provided clamping assembly, the two sides of the control box 2 can be clamped and fixed when the control box 2 contacts the fixing seat 3, further preventing the control box 2 from falling and colliding with the machine tool due to loose screws when no one is around, causing damage to the equipment. After the control box 2 slides down and is fixed and clamped against the fixing seat 3, the alarm assembly can also be used to emit an alarm sound to remind the staff that the control box 2 has slipped, so that the staff can perform maintenance on the control box 2 in time.

When the positioning plate 4 is completely against the fixing seat 3, the card slot 302 on the side wall of the fixing block 301 will move to a position flush with the card block 5. At this time, the force of the spring 1 501 is released, which will drive the card block 5 to rebound and return to its original position and bounce into the card slot 302 to fix the fixing seat 3. The fixed block 301 is locked, so that the control box 2 and the fixed seat 3 can be quickly fixed, and then the falling control box 2 can be supported and fixed to prevent the control box 2 from colliding with the machine tool and causing damage to the equipment. When the staff needs to disassemble the control box 2 and the fixed seat 3, they only need to unscrew the bolt 6 from the side wall of the positioning plate 4, and then pull the block 5 back into the slide groove 402 through the pull rope 601 and disengage from the slot 302. At this time, the fixed block 301 is loosened, so that the control box 2 and the fixed seat 3 can be quickly disassembled.

10. A method for using a preventive maintenance system for electromechanical equipment according to claim 9, characterized in that: The following steps are involved: S1: When the machine tool equipment drives the control box (2) to vibrate for a long time during operation, causing the clamp screws to loosen, the control box (2) will slide down along the column (1), and when the positioning plate (4) at the bottom of the control box (2) abuts against the fixing seat (3), the fixing block (301) will be inserted into the slot (401), and at this time, the spring (501) will squeeze the clamping block (5) into the clamping groove (302) on the side wall of the fixing block (301), so that the falling control box (2) can be supported and fixed; S2: When the control box (2) slides down due to the loosening of the screws, the positioning plate (4) at the bottom thereof will also drive the fixing rod (10) to slide down. At this time, the fixing rod (10) will drive the rotating shaft (801) and the gear (802) on the support plate (7) to rotate through the tooth plate (11) at the bottom thereof, thereby driving the movable column (8) on the support plate (7) to flip upward. When the control box (2) and the fixing seat (3) are in contact with each other, the flipped movable column (8) will just drive the fixing head (9) to contact the two sides of the control box (2), thereby clamping and fixing the two sides of the control box (2); S3: When the control box (2) slides down, it will also contact the cleaning cylinders (1701) on the bracket (17). The cleaning cylinder (1701) is squeezed by the control box (2) and moves toward the outside of the fixed cylinder (15) through the slide bar (16). At this time, the cleaning cylinder (1701) will roll along the outer wall of the control box (2). When the control box (2) and the fixed seat (3) are in contact, the cleaning cylinder (1701) will stick to the front surface of the control box (2), which can not only clean the dust on the surface of the control box (2), but also cooperate with the spring three (1501) to squeeze and fix the front side of the control box (2); S4: After the control box (2) slides down, it will pull the rope (1401) wound around the reel (14), and the rope (1401) will pull the reel (14) and the rotating rod (13) to rotate. The torsion spring (1301) will have a resistance to hinder the rotation of the rotating rod (13) and the reel (14), thereby pulling and buffering the falling control box (2), so that the control box (2) can slowly slide down and contact the fixed seat (3); S5: After the control box (2) slides down and contacts the fixing seat (3), the fixing rod (10) and the tooth plate (11) at the bottom thereof will also drive the pressing rod (1101) to move downward and just squeeze the switch (1901) on the connecting plate (1801), thereby activating the alarm (19) to sound an alarm to remind the staff that the control box (2) has slipped due to the loosening of the clamp screws.
