[0017] The present invention will be further described below with reference to specific embodiments. Please refer to the following description. Figures 1 to 4 :
[0018] Example 1: A column degreasing device for the production of mining hydraulic supports includes a support frame 1. The upper end of the support frame 1 is provided with an oil removal tank 2 and a rinsing tank 3. The oil removal tank 2 is provided with cleaning fluid. The lower end of the oil removal tank 2 is provided with a drain valve 4 for draining the cleaning fluid in the oil removal tank 2. The inside of the oil removal tank 2 is provided with a bracket 5, and a brush plate 6 is provided on the bracket 5.
[0019] Two support arms 7 are slidably installed inside the oil removal tank 2. Both support arms 7 slide horizontally and are equipped with a drive mechanism 8. The drive mechanism 8 includes a drive shaft 9. The free end of the drive shaft 9 is provided with a limit post 10. The outer side of the limit post 10 is provided with a rubber ring 11. The limit post 10 extends coaxially. When installing the column, the column is placed between the two limit posts 10, and the two support arms 7 are controlled to move closer to each other. The two limit posts 10 are inserted into the two ends of the column to fix the column. At the same time, the side of the column contacts the brush plate 6 and is immersed in the cleaning solution. The length of the brush plate 6 is longer than the length of the column.
[0020] Two drive mechanisms 8 control two drive shafts 9 to rotate synchronously. The friction between the rubber ring 11 outside the limit post 10 and the inner wall of the column drives the column to rotate. During the rotation of the column, the brush plate 6 removes oil from the side of the column. Compared with the oil removal method of soaking and rinsing only, the oil removal effect is better.
[0021] Two telescopic rods 14 are installed inside the rinsing pool 3. One telescopic rod 14 is connected to a rinsing pipe, and the other telescopic rod 14 is connected to a drain pipe. A slider 15 is slidably installed inside the rinsing pool 3. A rinsing ring 16 is installed on the slider 15. Multiple pressurizing nozzles are installed on the inner side of the rinsing ring 16. A water supply mechanism 18 is installed at the lower end of the rinsing pool 3, which is connected to both the rinsing ring 16 and the rinsing pipe. The water supply mechanism 18 is connected to the rinsing ring 16 and the rinsing pipe by means of a flexible hose.
[0022] After the column is degreased, it is moved into the rinsing tank 3. The two telescopic rods 14 are extended, and the rinsing pipe and drain pipe are inserted into the two ends of the column respectively. The water supply mechanism 18 supplies water to the rinsing pipe and the rinsing ring 16. The slider 15 drives the rinsing ring 16 to move. The rinsing ring 16 rinses the cleaning fluid remaining on the outside of the column, and the rinsing pipe rinses the cleaning fluid remaining inside the column to reduce the residue of the cleaning fluid.
[0023] Example 2: A column degreasing device for producing mining hydraulic supports, comprising a support frame 1, an oil removal tank 2 and a rinsing tank 3 at the upper end of the support frame 1, a cleaning fluid in the oil removal tank 2, a drain valve 4 at the lower end of the oil removal tank 2 for draining the cleaning fluid in the oil removal tank 2, a bracket 5 inside the oil removal tank 2, and a brush plate 6 on the bracket 5.
[0024] Two support arms 7 are slidably installed inside the oil removal tank 2. Both support arms 7 slide in the horizontal direction. Each support arm 7 is equipped with a drive mechanism 8, which includes a drive shaft 9. The free end of each drive shaft 9 is provided with a limit post 10. A rubber ring 11 is provided on the outer side of each limit post 10. The limit posts 10 extend coaxially. When installing the column, the column is placed between the two limit posts 10, and the two support arms 7 are controlled to move closer to each other. The column is then fixed by inserting the two limit posts 10 into both ends of the column.
[0025] The oil removal tank 2 is equipped with a lifting frame 12. The upper end of the lifting frame 12 is equipped with an arc plate 13. The lifting frame 12 and the arc plate 13 are used to support the column. After the column is fixed, the lifting frame 12 is controlled to descend so that the arc plate 13 is separated from the column. The side of the column contacts the brush plate 6 and is immersed in the cleaning solution. The length of the brush plate 6 is longer than the length of the column.
[0026] The drive mechanism 8 includes a waterproof box, inside which a servo motor is installed. The servo motor is equipped with a drive shaft 9 extending outside the waterproof box and a power cable. The drive shaft 9 is rotatably and sealed to the waterproof box. A controller is installed on the side of the degreasing tank 2, and the controller is connected to both servo motors.
[0027] Two drive mechanisms 8 control two drive shafts 9 to rotate synchronously. The friction between the rubber ring 11 outside the limit post 10 and the inner wall of the column drives the column to rotate. During the rotation of the column, the brush plate 6 removes oil from the side of the column. Compared with the oil removal method of soaking and rinsing only, the oil removal effect is better.
[0028] Two telescopic rods 14 are installed in the rinsing tank 3. One telescopic rod 14 is connected to a rinsing pipe, and the other telescopic rod 14 is connected to a drain pipe. The telescopic rods 14 are hydraulic telescopic rods 14. A hydraulic station and a hydraulic control unit connected to the hydraulic telescopic rods 14 are installed below the oil removal tank 2. A slider 15 is slidably installed in the rinsing tank 3. A rinsing ring 16 is installed on the slider 15. Multiple booster nozzles are installed on the inner side of the rinsing ring 16. A water supply mechanism 18 is installed at the lower end of the rinsing tank 3, which is connected to the rinsing ring 16 and the rinsing pipe. The water supply mechanism 18 is connected to the rinsing ring 16 and the rinsing pipe by a hose.
[0029] After the column is degreased, it is moved into the rinsing tank 3. The two telescopic rods 14 are extended, and the rinsing pipe and drain pipe are inserted into both ends of the column. The water supply mechanism 18 supplies water to the rinsing pipe and the rinsing ring 16. The slider 15 drives the rinsing ring 16 to move. The rinsing ring 16 rinses the cleaning fluid remaining on the outside of the column, and the rinsing pipe rinses the cleaning fluid remaining inside the column to reduce the residue of cleaning fluid. The upper ends of the rinsing tank 3 and the degreasing tank 2 are both hinged with anti-splash covers 19 to reduce liquid splashing during the degreasing and cleaning of the column.
[0030] The specific working principle is as follows:
[0031] The lifting frame 12 is raised to place the column onto the arc-shaped plate 13. The height of the lifting frame 12 is adjusted until the limiting post 10 can be inserted into the column. The two support arms 7 are brought closer together, thus fixing the column by inserting the two limiting posts 10 into both ends of the column. Then, the lifting frame 12 is lowered to detach the arc-shaped plate 13 from the column. The two drive mechanisms 8 are rotated synchronously, and the brush plate 6 is used to clean and remove oil from the outside of the column. After degreasing, the drive mechanism 8 is turned off, and the lifting frame 12 is raised to support the column. Both rocker arms move outward to detach the limiting posts 10 from the column.
[0032] Move the column to the rinsing pool 3, control the extension of the two telescopic rods 14, insert the rinsing pipe and drain pipe into the two ends of the column respectively, supply water to the rinsing pipe and rinsing ring 16, and the slider 15 drives the rinsing ring 16 to move. The rinsing ring 16 rinses the cleaning fluid remaining on the outside of the column, and the rinsing pipe rinses the cleaning fluid remaining inside the column. After rinsing, control the telescopic rods 14 to shorten and remove the column.
