[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 2 - Figure 5 The utility model provides an embodiment of a disassembly device for the rear brake caliper piston of a mining vehicle, comprising an oil cylinder 1, the inner wall of the oil cylinder 1 is slidably connected to the piston body 2, the outer wall of the piston body 2 is fixedly connected to a connecting column 7, the connecting column 7 is usually made of high-strength alloy steel and has good bearing capacity, the outer wall of the connecting column 7 is fixedly connected to a screw ring 8, the screw ring 8 can be made of corrosion-resistant stainless steel, the surface has an anti-slip texture, and is easy to operate, the outer wall of the screw ring 8 is rotatably connected to the connecting ring 4, the connecting ring 4 is slidably connected to the inner wall of the oil cylinder 1, one side of the connecting ring 4 is fixedly connected to a spring 5, one side of the spring 5 is fixedly connected to a fixing block 6, the fixing block 6 is fixedly connected to the inner wall of the oil cylinder 1, a plurality of rotating shafts 9 are fixedly connected inside the connecting column 7, the outer walls of the rotating shafts 9 are all rotatably connected to a card plate 10, the card plate 10 is usually made of high-strength alloy steel, has good wear resistance and deformation resistance, and the inner walls of the card plate 10 are all fixedly connected to the spring 2. 11. Spring 2. 11 has a high elastic coefficient and good toughness, can withstand greater pressure and quickly return to its original shape. One side of spring 2. 11 is fixedly connected to a base plate 12, which can be made of aluminum alloy, which not only ensures a certain strength but also has a lighter weight. A stabilizing component is provided on the outer wall of the connecting ring 4. The stabilizing component is used to enhance the stability of the piston connection. The stabilizing component includes a baffle 18, which is provided on both sides of the connecting ring 4. A plurality of slides 13 are fixedly connected on both sides of the base plate 12. The slides 13 are generally made of stainless steel with higher hardness, and the surface is finely processed to ensure smooth sliding. The outer walls of the slides 13 on both sides are slidably connected to a fixed plate 14, which can be made of cast iron and has higher strength and stability. The size of the internal groove is precisely designed to strictly limit and guide the movement of the slide 13, and the fixed plate 14 is fixedly connected to the inside of the connecting column 7.

[0035] Specifically, when inspecting or repairing a piston for damage, it is often necessary to disassemble it. First, press the card plate 10. When under pressure, the card plate 10 will drive the spring 2 11 to squeeze. When being squeezed inward, the spring 2 11 will drive the bottom plate 12 to move. The moving force of the bottom plate 12 is transmitted to the outer wall of the slide bar 13, driving the slide bar 13 to slide in the groove inside the fixed plate 14, ensuring that the bottom plate 12 always moves in a straight line during the movement without deviation or shaking. When the card plate 10 shrinks to the inside of the connecting column 7, by rotating the screw ring 8, which can be made of corrosion-resistant stainless steel with an anti-slip texture on the surface for easy operation, rotating the screw ring 8 will drive the connecting column 7 to be pulled out from the inner wall of the connecting ring 4, so that the piston can be quickly disassembled.

[0036] Reference Figure 1 and Figure 6 , the outer wall of the connecting column 7 is fixedly connected with a plurality of connecting strips 3, the connecting strip 3 is arranged on one side of the connecting ring 4, and the two sides of the connecting ring 4 are fixedly connected with a fixing plate 2 15, and the outer wall of the fixing plate 2 15 is fixedly connected with a spring 3 16, and the elastic coefficient of the spring 3 16 is moderate and can provide a stable rebound force. The spring 3 16 is fixedly connected to one side of the connecting plate 17, and the connecting plate 17 is fixedly connected to the outer wall of the baffle 18. The baffle 18 can be made of high-strength aluminum alloy material, and the surface is anodized, which is both beautiful and has good corrosion resistance. The baffle 1 8 are all fixedly connected with the rotating shaft 2 19 inside. The rotating shaft 2 19 is usually made of high-quality alloy steel, has high strength and wear resistance, and can ensure the smooth rotation. The outer wall of the rotating shaft 2 19 is rotatably connected with the fixed block 20. The fixed block 20 is fixedly connected to both sides of the connecting ring 4. The outer wall of the baffle 18 is fixedly connected with the connecting block 21. The outer wall of the connecting block 21 is provided with a fixing ring 22. The fixing ring 22 can be made of high-strength cast iron, has good stability and load-bearing capacity, and the fixing ring 22 is fixedly connected to the outer wall of the connecting column 7.

[0037] Specifically, when replacing a new piston, you first need to press one side of the baffle 18. When pressing one side of the baffle 18, the other side of the baffle 18 and the connecting block 21 will be driven to rotate and move through the rotating shaft 2 19. Then, the connecting column 7 on one side of the piston is moved to the inside of the connecting ring 4, and the inner wall of the connecting ring 4 is used to squeeze the card plate 10. When the card plate 10 completely passes through the connecting ring 4, the rebound force of the spring 2 11 is used to drive the card plate 10 to expand, so that the connecting ring 4 is used to block the card plate 10 to prevent the connecting column 7 from sliding from the inner wall of the connecting ring 4. Finally, rotate the screw ring 8 again to achieve a good fixation between the connecting column 7 and the connecting ring 4, and finally release the squeezing force on one side of the baffle 18, so as to use the rebound force of the spring three 16 to drive the connecting block 21 to move to the inside of the fixing ring 22. The connecting block 21 moves to the inside of the fixing ring 22 under the action of the spring three 16, and the baffle 18 and the connecting block 21 are used to block one side of the fixing ring 22 to prevent the screw ring 8 from loosening, thereby causing the position of the fixing ring 22 to shift, thereby enhancing the stability of the connection between the connecting column 7 and the connecting ring 4.

[0038] Working principle: When the piston is damaged or needs to be disassembled for repair, first press the card plate 10. When the card plate 10 is under pressure, it will drive the spring 2 11 to be squeezed. When the spring 2 11 is squeezed inward, it will drive the bottom plate 12 to move. The moving force of the bottom plate 12 is transmitted to the outer wall of the slide bar 13, driving the slide bar 13 to slide in the internal groove of the fixed plate 14. The fixed plate 14 is used to limit and guide the movement of the slide bar 13 to ensure that the bottom plate 12 always keeps moving in a straight line. When the card plate 10 shrinks to the inside of the connecting column 7, the screw ring 8 is rotated to drive the connecting column 7 to be pulled out from the inner wall of the connecting ring 4, thereby realizing quick disassembly of the piston. When replacing a new piston, first press one side of the baffle 18, thereby driving the other side of the baffle 18 and the connecting block 21 to rotate and move through the rotating shaft 2 19. Then the connecting column 7 on one side of the piston is moved to the inside of the connecting ring 4, and the inner wall of the connecting ring 4 is used to squeeze the card plate 10. When the card plate 10 completely passes through the connecting ring 4, the rebound force of the spring 2 11 is used to drive the card plate 10 to expand, so that the connecting ring 4 is used to block the card plate 10 to prevent the connecting column 7 from sliding from the inner wall of the connecting ring 4, and then the screw ring 8 is rotated again to achieve a good fixation between the connecting column 7 and the connecting ring 4, and finally release the squeezing force on one side of the baffle 18, so as to use the rebound force of the spring 3 16 to drive the connecting block 21 to move to the inside of the fixing ring 22, and use the baffle 18 and the connecting block 21 to block one side of the fixing ring 22 to prevent the screw ring 8 from loosening and causing the position of the fixing ring 22 to shift, thereby enhancing the stability of the connection between the connecting column 7 and the connecting ring 4.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
