[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model provides a technical solution, a hydraulic control device for a cantilever stacker, comprising a mounting plate 1, a slide rail 2 is mounted on the top of the mounting plate 1, a limiting groove 3 is provided on one side end surface of the slide rail 2, a sliding base 4 is slidably mounted on the outer side of the slide rail 2, a plurality of threaded fixing grooves 5 are symmetrically provided on the top of the mounting plate 1, a positioning groove 6 is provided at the middle position of the top of the mounting plate 1, and a limiting slide groove 7 is provided at the bottom of the sliding base 4 and at the corresponding position of the slide rail 2;

[0024] A fixing groove 8 is provided on the side end surface of the sliding base 4, and a fixing rod 9 is embedded in the inner side of the fixing groove 8. The diameter of the fixing rod 9 is equal to the side length of the fixing groove 8, and the fixing rod 9 is rotatably connected to the fixing groove 8. The fixing groove 8 is symmetrically arranged on the two side end surfaces of the sliding base 4, which is convenient for the threaded rod 11 to adjust the angle. A connecting rod 10 is welded on the outer side of the fixing rod 9, and the outer side of the connecting rod 10 is threadedly connected with the threaded rod 11. A fixing block 12 is slidably clamped on the inner side of the slide rail 2, and a clamping block 13 is welded on the bottom end of the fixing block 12. A clamping groove 14 is provided on the side end surface of the fixing block 12, and the threaded rod 11 is embedded in the inner side of the clamping groove 14. The clamping block 13 is embedded in the inner side of the positioning groove 6, which is conducive to fixing the sliding base 4. A hydraulic cylinder body 15 is rotatably installed on the inner side of the sliding base 4. Two slide rails 2 are provided, and the two slide rails 2 are symmetrically installed at the top position of the mounting plate 1. A rotating groove is provided at the inner side of the sliding base 4 and the corresponding position of the hydraulic cylinder body 15, which is convenient for the hydraulic cylinder body 15 to adjust the angle.

[0025] A piston rod 16 is slidably embedded in the inner side of the hydraulic cylinder body 15, and a clamping sleeve 17 is slidably sleeved on the outer side of the hydraulic cylinder body 15. A fixing screw 18 is threadedly connected to the outer side of the clamping sleeve 17, and a transparent dustproof net 19 is sleeved on the outer side of the clamping sleeve 17. The other end of the transparent dustproof net 19 is sleeved on the outer side of the top sleeve 20. Threaded holes are provided on the inner side of the clamping sleeve 17 at positions corresponding to the fixing screw 18 to facilitate dust prevention. The top sleeve 20 is slidably sleeved on the outer side of the piston rod 16.

[0026] The working principle and use process of the utility model are as follows: first, when installing the cantilever stacker, the operator first fixes the mounting plate 1 on the base of the cantilever stacker through the fire nut through the threaded fixing groove 5, and then after determining the upper use height of the cantilever stacker, the operator connects the piston rod 16 to the conveying arm of the cantilever stacker, and then slides the sliding base 4 through the limiting slide groove 7 and snaps it into the outside of the slide rail 2. At this time, the limiting groove 3 and the limiting slide groove 7 are snapped with each other, and then the operator slides the sliding base 4 on the outside of the slide rail 2, thereby adjusting the hydraulic cylinder body 15 to a suitable position. At this time, after the hydraulic cylinder body 15 slides to a position that can be used normally, the fixing rod 9 is snapped into the inner side of the fixing groove 8, and the hydraulic cylinder body 15 is adjusted to a suitable position. The fixing block 12 is inserted into the inner side of the positioning groove 6 through the clamping block 13, thereby fixing the fixing block 12, and then one end of the threaded rod 11 is rotated and inserted into the inside of the clamping groove 14. After the threaded rod 11 cannot be twisted, it means that the distance between the connecting rod 10 and the threaded rod 11 has reached the maximum position. At this time, the fixing blocks 12 on both sides fix the position of the sliding base 4 through the connecting rod 10 and the threaded rod 11. Subsequently, when the height of the cantilever stacker needs to be adjusted, the position of the sliding base 4 can be moved on the top of the slide rail 2 according to the adjustment height. It is very convenient to use, and there is no need to disassemble the hydraulic device, which reduces the working steps and reduces the time required for adjusting the height of the cantilever stacker, thereby improving work efficiency;

[0027] Next, the clamping sleeve 17 is sleeved on the outside of the hydraulic cylinder body 15, and then the fixing screw 18 is tightened, and then the top sleeve 20 is fixed on the outside of the piston rod 16. At this time, when the piston rod 16 is continuously extended and retracted, the top sleeve 20 will rise and fall with the piston rod 16, so the transparent dustproof net 19 will always be sleeved on the outside of the piston rod 16, thereby preventing a large amount of dust at the use site of the cantilever stacker from sticking to the surface of the piston rod 16, ensuring that the surface of the piston rod 16 will not be attached by debris, thereby ensuring the surface lubricity of the piston rod 16, allowing the piston rod 16 to slide smoothly, and improving the stability of the hydraulic device.

[0028] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
