Description

Technical Field

[0001] The present application relates to the technical field of mechanical maintenance, and particularly relates to a maintenance table for mechanical maintenance. Background Art

[0002] Mechanical maintenance refers to a technical means of using relevant tools and technical means to restore mechanical equipment to normal operation, improve its performance, extend its service life, and at the same time carry out equipment installation, debugging and technical support. Mechanical maintenance is crucial for maintaining the normal operation of equipment and extending its service life, and is of great significance for improving production efficiency and reducing production costs.

[0003] During the process of mechanical maintenance, mechanical equipment needs to be placed on a maintenance table for maintenance. The traditional maintenance table for mechanical maintenance is merely an operating table, and it is difficult to adjust the height according to the height of the operator and the change of the mechanical maintenance position. Some maintenance tables are provided with hydraulic cylinders below for lifting the maintenance table, but after multiple lifts, the hydraulic cylinders will be worn under the pressure of the maintenance table and the equipment, which is not conducive to long-term use. Moreover, dust and debris are often generated during mechanical maintenance, which has an adverse impact on the health of the staff. Therefore, to solve the above problems, the present application provides a maintenance table for mechanical maintenance.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0005] In order to solve the problems that the hydraulic cylinders used for lifting the maintenance table are easily damaged under pressure and dust affects the health of the body, the present application provides a maintenance table for mechanical maintenance.

[0006] A maintenance table for mechanical maintenance provided by the present application includes a bottom plate and two side plates fixedly connected to both sides thereof. A maintenance platform is arranged between the two side plates. Two connecting rods are fixedly connected below the maintenance platform. Moving plates are fixedly connected below the connecting rods. The moving plates are both provided with through holes and are threadedly connected with two second screws. Four rotating rods are rotatably arranged on the upper wall of the bottom plate. The four rotating rods rotate synchronously and in the same direction and are respectively coaxially fixedly connected to a second screw.

[0007] Preferably, a cross bar is rotatably arranged between the two side plates. A second motor for driving the cross bar to rotate is fixedly arranged on the side plate. Four worm gears are coaxially fixedly connected to the cross bar.

[0008] Preferably, worm wheels are coaxially fixedly connected to the rotating rods, and the worm gears are respectively engaged with a worm wheel.

[0009] Preferably, two electromagnets are fixedly arranged on both sides of the maintenance platform. One end of each electromagnet away from the maintenance platform is fixedly connected with a telescopic rod, and one end of each telescopic rod away from the maintenance platform is fixedly connected with a permanent magnet. The ends of the energized electromagnet and the permanent magnet close to each other have opposite magnetic polarities.

[0010] Preferably, the telescopic rod is wound with a spring, and the permanent magnet is elastically connected to the electromagnet through the spring.

[0011] Preferably, four groups of limiting holes are formed in the side wall of the side plate. Each group of limiting holes has several and is arranged vertically. One end of the permanent magnet away from the maintenance platform is fixedly connected with a limiting rod, and the limiting rod is slidably connected to the side plate through the limiting holes.

[0012] Preferably, a first screw rod is rotatably arranged between the two side plates. The first screw rod is located above the maintenance platform. The side plate is fixedly provided with a first motor for driving the first screw rod to rotate. The first screw rod is provided with a through hole and is threadedly connected with a dust suction assembly.

[0013] Preferably, two cover plates are fixedly arranged between the two side plates.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] By energizing the electromagnet, the permanent magnet moves to drive the limiting rod to disengage from the limiting hole. Then, start the second motor. The cross bar drives the four worm gears to rotate, so that the four worm wheels drive the rotating rod to rotate. At this time, the four second screw rods rotate, and the two moving plates threadedly connected to the second screw rods rise or fall synchronously. The maintenance platform is driven to move through the connecting rod. When it moves to a suitable position, the electromagnet is powered off. Due to the action of the spring, the limiting rod moves and abuts against the side plate. Then, the height of the maintenance platform is finely adjusted through the second motor until the limiting rod slides into the limiting hole under the action of the spring. Compared with the traditional maintenance table, not only the height can be adjusted, but also the pressure on the lifting structure is reduced during maintenance, and the service life of the equipment is increased.

[0016] By driving the dust suction assembly to move through the rotation of the first motor, after the dust suction assembly is started, the debris and dust generated during mechanical maintenance can be adsorbed, ensuring the cleanliness of the working environment.

Detailed implementation mode

[0021] The following further elaborates on this application in conjunction with the attached drawings. Figures 1-3 Make a further detailed description of this application.

[0022] Embodiment 1

[0023] Referring to Figures 1-3 , a maintenance platform for mechanical maintenance, includes a bottom plate 21 and two side plates 1 fixedly connected to both sides thereof, and two cover plates 2 are fixedly arranged between the two side plates 1.

[0024] A maintenance platform 3 is arranged between the two side plates 1. Two connecting rods 7 are fixedly connected to the lower part of the maintenance platform 3. Moving plates 8 are fixedly connected to the lower parts of the connecting rods 7. The moving plates 8 are both provided with through holes and are threadedly connected with two second screws 9. Four rotating rods 10 are rotatably arranged on the upper wall of the bottom plate 21. The four rotating rods 10 rotate synchronously and in the same direction and are respectively coaxially fixedly connected to a second screw 9.

[0025] A cross bar 13 is rotatably arranged between the two side plates 1. The side plate 1 is fixedly provided with a second motor 14 for driving the cross bar 13 to rotate. Four worms 12 are coaxially fixedly connected to the cross bar 13. Worm gears 11 are coaxially fixedly connected to the rotating rods 10 respectively. The worms 12 are respectively meshed with a worm gear 11.

[0026] Two electromagnets 15 are fixedly arranged on both sides of the maintenance platform 3. The power supply of the electromagnet 15 is located inside the maintenance platform 3. One end of the electromagnet 15 away from the maintenance platform 3 is fixedly connected with a telescopic rod 17. One end of the telescopic rod 17 away from the maintenance platform 3 is fixedly connected with a permanent magnet 16. The ends of the energized electromagnet 15 and the permanent magnet 16 close to each other have opposite magnetic polarities. A spring 18 is wound around the telescopic rod 17. The permanent magnet 16 is elastically connected to the electromagnet 15 through the spring 18.

[0027] Four groups of limit holes 19 are opened on the side wall of the side plate 1. Each group of limit holes 19 has several and is arranged vertically. One end of the permanent magnet 16 away from the maintenance platform 3 is fixedly connected with a limit rod 20. The limit rod 20 is slidably connected to the side plate 1 through the limit hole 19.

[0028] A first screw rod 5 is rotatably arranged between two side plates 1. The first screw rod 5 is located above the maintenance platform 3. A first motor 6 for driving the first screw rod 5 to rotate is fixedly arranged on the side plate 1. The first screw rod 5 is provided with a through hole and is threadedly connected with a dust suction assembly 4, forming a structure similar to a ball screw. The dust suction assembly 4 is a common vacuum cleaner on the market and is an existing mature technology.

[0029] During the actual use process, first, the electromagnet 15 is energized, and the permanent magnet 16 moves to drive the limiting rod 20 to disengage from the limiting hole 19. Then, the second motor 14 is started, and the cross bar 13 drives the four worm rods 12 to rotate. Thus, the four worm wheels 11 drive the rotating rod 10 to rotate. At this time, the four second screw rods 9 rotate, and the two moving plates 8 threadedly connected with the second screw rods 9 move up or down synchronously. The maintenance platform 3 is driven to move through the connecting rod 7. When it moves to a suitable position, the electromagnet 15 is powered off. Due to the action of the spring 18, the limiting rod 20 moves and abuts against the side plate 1. Then, the height of the maintenance platform 3 is finely adjusted through the second motor 14 until the limiting rod 20 slides into the limiting hole 19 under the action of the spring 18. During mechanical maintenance, the first motor 6 is started to drive the dust suction assembly 4 to move. After the dust suction assembly 4 is started, it can adsorb the debris and dust generated during mechanical maintenance.

[0030] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly.
