Description

Technical Field

[0002] Hydraulic cylinder repair adopts a production line operation mode, which is a way to achieve repair through standardized processes, professional equipment and division of labor. Compared with traditional piecemeal repair or manual single-machine operation, it has significant advantages and greatly improves the repair speed.

[0003] The production line breaks down the repair process into several sub-processes, mainly targeting the cutting, grinding, rust removal, and welding operations in manual repair. In the current actual manual repair operation, due to the variety of hydraulic cylinders, the various processes cannot be seamlessly connected, resulting in low repair efficiency. Moreover, the cutting and grinding operations generate a large amount of metal shavings. If these shavings are not cleaned in time, they will not only accumulate on the workbench and affect the normal progress of subsequent processes, but may also adhere to the surface or gaps of the hydraulic cylinder, leading to accelerated wear and sealing failure during the use of the repaired hydraulic cylinder, resulting in a generally poor repair effect.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an intelligent automated integrated production line system for repairing hydraulic cylinders of mining hydraulic supports. The intelligent automated integrated production line system for repairing hydraulic cylinders of mining hydraulic supports includes a production line component 1, a rotating component 2, and an air jet cleaning component 3. The displacement groove 22-1 cooperates with the displacement block 27 to guide the toothed plate 28 to a stable displacement, so that the gear 26 rotates smoothly. The motor 24-1 in the rotating component 24 serves as a power source. Through the displacement slider 24-3 and the U-shaped block 24-4, the rotational motion of the motor is converted into the linear displacement of the toothed plate 28. Then, through the meshing of the gear 26 and the toothed plate 28, the rotation of the hydraulic support cylinder body 29 is realized.

[0037] The hollow tube 31 and multiple jet nozzles 36 in the jet cleaning assembly 3 can perform jet cleaning on the surface of the hydraulic support cylinder body 29 in a timely manner during rotation, effectively removing metal shavings generated by cutting and grinding. The arc groove 32-1 on the surface of the round rod 32 is slidably connected to the steel ball 33-1 embedded in the inner ring of the ring 33, which not only ensures that the ring 33 can rotate stably with the round rod 32, but also achieves gas sealing transmission during rotation through the sealing piston 34 and the air outlet pipe 35, ensuring stable jetting by the jet nozzles 36.

[0038] Specifically, the production line component 1 includes a production line body 11, and the top of the production line body 11 is respectively provided with a cutting and grinding component 12, a laser rust removal component 13, a new block gripping component 14, and a new block automatic welding component 15.

[0039] Specifically, the rotating component 2 is disposed on the top of the production line body 11, including a mounting plate 21 slidably connected to the top of the production line body 11. A hydraulic support cylinder body 29 is disposed on the top of the mounting plate 21. A first fixing plate 22 is fixed on the top of the mounting plate 21. A displacement groove 22-1 is formed on the surface of the first fixing plate 22. A second fixing plate 23 is fixed on the top of the mounting plate 21. A rotating component 24 is disposed on the surface of the second fixing plate 23.

[0040] Specifically, the jet cleaning assembly 3 is located on the top of the mounting plate 21 and includes a hollow tube 31 fixed to the top of the mounting plate 21. A connecting rod 25 is provided on the top of the mounting plate 21, and a round rod 32 is fixed to one end of the connecting rod 25. The round rods 32 are symmetrically arranged, and an arc groove 32-1 is opened on the surface of the round rod 32. A ring 33 is slidably connected to the outer ring of the round rod 32, and a steel ball 33-1 is embedded in the inner ring of the ring 33.

[0041] The cutting and grinding component 12 is specifically designed for precise cutting of damaged parts, worn valve blocks, and hydraulic pipes on the surface of the hydraulic support cylinder body 29. Based on the degree of damage and repair needs of the hydraulic support cylinder body 29, it removes defective areas, laying a good foundation for subsequent grinding and rust removal processes. The cutting and grinding component 12 is used to finely grind the surface of the cut hydraulic support cylinder body 29, effectively eliminating burrs, sharp edges, and surface wear marks left from cutting, resulting in a smooth and flat surface. The laser rust removal component 13 removes the rust layer from the surface of the hydraulic support cylinder body 29, solving the problem of incomplete rust removal in traditional repair methods. It can penetrate deep into the gaps and depressions on the surface of the hydraulic support cylinder body 29, thoroughly removing rust and restoring the original performance of the metal body.

[0042] Example 2

[0043] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, it also includes a motor 24-1 fixed on one side of the second fixing plate 23, a rotating rod 24-2 fixed at the output end of the motor 24-1, and a displacement slider 24-3 fixed at one end of the rotating rod 24-2.

[0045] Specifically, the connecting rod 25 is fitted with a gear 26, and a toothed plate 28 is slidably connected to one side of the first fixing plate 22.

[0046] Specifically, it also includes a U-shaped block 24-4 slidably connected to the surface of the displacement slider 24-3, and the toothed plate 28 meshing with the gear 26.

[0047] Specifically, it also includes the U-shaped block 24-4 fixed to one side of the toothed plate 28, and the bottom of the toothed plate 28 is fixed with a displacement block 27.

[0048] The mounting plate 21 serves as the base platform for supporting the hydraulic support cylinder body 29. Its design, which allows it to slide and connect to the top of the production line body 11, enables it to move to a designated position according to the needs of different processes, greatly improving the continuity of the production process. The first fixing plate 22, with its displacement groove 22-1 on the surface, provides a displacement track for the sliding of the displacement block 27, allowing the toothed plate 28 to move smoothly.

[0049] The displacement groove 22-1, in conjunction with the displacement block 27, provides a stable path for the linear motion of the toothed plate 28, ensuring the stability of the toothed plate 28 during movement and preventing wobbling and deviation.

[0050] By setting the displacement slider 24-3, it can be used in conjunction with the rotating rod 24-2 and the U-shaped block 24-4. When the rotating rod 24-2 rotates, the displacement slider 24-3 performs circular motion under its drive. At the same time, since it is slidably connected with the U-shaped block 24-4, the circular motion can be converted into the linear motion of the U-shaped block 24-4. The rotational power of the motor 24-1 can be converted into the linear power that pushes the toothed plate 28 to move, thereby realizing the smooth rotation of the hydraulic support cylinder body 29.

[0051] Specifically, the surface of the displacement block 27 is slidably connected to the inner wall of the displacement groove 22-1, and the bottom of the hollow tube 31 is fixed with an air jet head 36.

[0052] Specifically, it also includes two hollow tubes 31 and several jet heads 36.

[0053] Specifically, the steel ball 33-1 is slidably connected to the inner wall of the arc groove 32-1, and a sealing piston 34 is slidably connected to the top of the ring 33.

[0054] Specifically, it also includes an air outlet pipe 35 provided at one end of the sealing piston 34, with one end of the sealing piston 34 located in the inner cavity of the air outlet pipe 35.

[0055] Specifically, it also includes one end of the air outlet pipe 35 communicating with the inner cavity of the hollow tube 31, and the surface of the sealing piston 34 being slidably connected to the inner wall of the air outlet pipe 35.

[0056] By setting the hollow tube 31, different parts of the hydraulic support cylinder body 29 can be cleaned by air jets to achieve full coverage. Several air jet heads 36 fixed at the bottom of the hollow tube 31 can evenly spray compressed air onto the surface of the hydraulic support cylinder body 29 to form a uniform cleaning airflow.

[0057] By setting the arc groove 32-1, the air jet cleaning component 3 can work automatically in cooperation with the steel ball 33-1. When the round rod 32 rotates, the steel ball 33-1 rolls in the arc groove 32-1. Due to the special shape of the arc groove 32-1, the steel ball 33-1 will push the ring 33 to reciprocate along the axis of the round rod 32. This reciprocating motion controls the flow of compressed air in the air outlet pipe 35 through the sealing piston 34, so that the air jet head 36 can regularly spray air for cleaning.

[0058] By setting the sealing piston 34, when the ring 33 moves upward under the action of the steel ball 33-1 and the arc groove 32-1, the sealing piston 34 will open the air outlet pipe 35, allowing compressed air to enter the hollow pipe 31 and be ejected through the jet nozzle 36. When the ring 33 moves downward, the sealing piston 34 will close the air outlet pipe 35 and stop the jetting.

[0059] Example 3

[0060] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0061] Specifically, production line component 1 also includes new block automatic welding component 15, accompanying tooling unloading 16, track conveyor line 17, new block belt conveyor line 18, new block loading platform 19, new block 110 and control platform 111. With control platform 111 as the core control unit, the staff first places the hydraulic support cylinder body 29 to be repaired onto the matching accompanying tooling. Then, control platform 111 issues a command to start track conveyor line 17. Track conveyor line 17 drives the accompanying tooling carrying the hydraulic support cylinder body 29 to flow sequentially to each functional station along the preset path of production line body 11.

[0062] The accompanying tooling triggers the photoelectric sensor in the positioning area, which sends a signal to the control platform 111. The control platform 111 then controls the industrial-grade high-stability 3D camera to start working. The industrial-grade high-stability 3D camera is a Hikvision 3D camera, model MV-DLS1400P. The 3D camera performs an all-round scan of the hydraulic support cylinder body 29 on the accompanying tooling through a preset industrial-grade mounting bracket. It focuses on collecting the spatial position, shape contour, and flatness data of the damaged part and the surface to be welded. The 3D camera transmits the collected three-dimensional data to the image processing module of the control platform 111 in real time. The module combines the original design model of the hydraulic support cylinder body 29 to analyze the boundary coordinates, defect volume, and undulation error of the surface to be polished in the damaged area. Based on the 3D visual positioning results, the control platform 111 sends control commands to the cutting and polishing part 12.

[0063] When the accompanying tooling arrives at the cutting and grinding station 12, the cutting and grinding station 12 performs cutting of the damaged area and grinding of the surface to be welded according to the size and shape of the damaged part of the hydraulic support cylinder body 29, so that the part of the hydraulic support cylinder body 29 to be repaired meets the welding accuracy requirements. After the cutting and grinding is completed, the track conveyor line 17 continues to transport the hydraulic support cylinder body 29 to the laser rust removal part 13 for rust removal, and after rust removal, it is sent to the new block gripper 14.

[0064] Meanwhile, the new block 111, which is pre-stored on the new block loading platform 19, is transported to the new block 110 gripping area via the new block belt conveyor 18. The new block gripper 14 grips the new block after receiving the signal from the control platform 111. The track conveyor 17 transports the combination of the hydraulic support cylinder body 29 and the new block 111 to the new block automatic welding station 15.

[0065] After the welding process is completed, the track conveyor 17 transports the repaired hydraulic support cylinder body 29 and accompanying tooling to the accompanying tooling unloading station 16. The accompanying tooling unloading station 16 separates the repaired hydraulic support cylinder body 29 from the accompanying tooling and transfers it to the finished product storage area. The empty accompanying tooling is returned to the initial loading end via the track conveyor 17 to prepare for the repair of the next batch of hydraulic support cylinder bodies 29. The entire repair process is monitored in real time by the control platform, realizing unmanned and automated continuous repair operations, effectively improving repair efficiency and product consistency.

[0066] In use, the production line component 1 carries the cutting and grinding parts 12, the laser rust removal parts 13, and the new block gripping parts 14 through the production line body 11, providing an operating platform for the repair of the hydraulic support cylinder body 29.

[0067] In the rotating assembly 2, the mounting plate 21 drives the cylinder body to slide and switch processes on the top of the production line body. The motor 24-1 drives the rotating rod 24-2 to rotate. Through the sliding cooperation of the displacement slider 24-3 and the U-shaped block 24-4, the rotational motion is converted into the linear motion of the toothed plate 28. Under the guidance of the displacement block 27 and the displacement groove 22-1, the toothed plate drives the gear 26 to rotate, thereby realizing the rotation of the cylinder body and ensuring the cutting operation.

[0068] Meanwhile, the gear drives the round rod 32 to rotate through the connecting rod 25. The arc groove 32-1 on the round rod cooperates with the steel ball 33-1 in the ring 33 to make the ring move axially, pushing the sealing piston 34 to control the opening and closing of the air outlet pipe 35, so that compressed air is ejected from the jet head 36 through the hollow pipe 31. During the cylinder repair process, metal waste is cleaned up simultaneously, realizing the coordinated and automated operation of repair and cleaning.

[0069] As can be seen from the above specific embodiments, this utility model patent can automate the repair process of hydraulic cylinders for mining hydraulic supports. It can effectively integrate processes such as cutting, grinding, laser rust removal, welding, and cleaning into a production line. Furthermore, by using 3D positioning technology and a control platform, it can achieve precision in the repair process of hydraulic cylinders for mining hydraulic supports. The automated process can replace manual labor, achieving the technical effects of safety, reliability, and improved efficiency.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
