Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As Figures 1 to 8 shown, a hydraulic coupling self-disassembly device according to an embodiment of the present invention includes a disassembly table 1. A pair of chutes 11 are opened at the top of the disassembly table 1. A slider 2 is slidably connected inside the chutes 11. A support plate 21 is fixedly connected to the top of the slider 2. A first hydraulic cylinder 22 is fixedly connected to the side of the support plate 21. The output end of the first hydraulic cylinder 22 is fixedly connected to a connecting plate 23. A clamping piece 24 is fixedly connected to the end of the connecting plate 23; A motor 25 is fixedly connected to the bottom end of the support plate 21. The output end of the motor 25 is fixedly connected to a gear 26. A rack 3 is meshed and connected below the gear 26. A pair of first connecting members are provided between the two ends of the rack 3 and the top of the disassembly table 1; The bottom end of the disassembly table 1 is fixedly connected with a lifting hydraulic cylinder 12. The output end of the lifting hydraulic cylinder 12 is located above the disassembly table 1, and a receiving member 13 is fixedly connected to the output end of the lifting hydraulic cylinder 12; When disassembling the coupling, a disassembly tool is needed to gradually disassemble and decompose the coupling; after disassembly and maintenance, the disassembled parts also need to be reinstalled; currently, when operating, the staff will place the disassembled parts aside and reassemble them after the maintenance is completed; however, since there are many parts in the hydraulic coupling, when reassembling the coupling parts after disassembly, it may be difficult for the staff to quickly find the required parts, thus affecting the assembly efficiency; to solve the above problems, the embodiments of the present invention are provided with a plurality of structures such as clamping pieces 24, sliders 2, and chutes 11; the specific usage process is as follows: when in use, place the hydraulic coupling to be disassembled on the top end of the receiving member 13; then start the lifting hydraulic cylinder 12 to control the up and down movement of the receiving member 13. When the receiving member 13 drives the coupling to a specified height, stop, and then start to disassemble the coupling; when disassembling, keep disassembling from the outside to the inside; specifically, when disassembling a part, control the first hydraulic cylinder 22 to start. The output end of the first hydraulic cylinder 22 drives the clamping piece 24 at the end of the connecting plate 23 to press against the side of the part being disassembled; a pair of clamping pieces 24 clamp and fix the disassembled part. When the part is disassembled, start the motor 25. The motor 25 drives the gear 26 to rotate. The gear 26 is in meshing transmission with the rack 3, so that the gear 26 drives the slider 2 at the bottom end of the support plate 21 to slide in the chute 11, and the support plate 21 drives the part clamped by the clamping piece 24 to move away from the coupling being disassembled; as the coupling is disassembled, the parts on the coupling are sequentially clamped and fixed above the disassembly table 1; the number of the clamping pieces 24 and the connecting structure is set according to needs; during the later installation, the positions of the parts can be restored in sequence, which is convenient for installation and helps to improve the installation efficiency; it should be noted that the improvement of the installation efficiency in this embodiment is due to the improvement of the disassembly method.

[0022] A pair of second hydraulic cylinders 231 are fixedly connected to the upper and lower sides of the connecting plate 23. A second connecting member is arranged between the second hydraulic cylinders 231 and the clamping pieces 24; for parts of different sizes, by starting the second hydraulic cylinders 231, the output ends of the second hydraulic cylinders 231 drive the second connecting members to move, and the second connecting members drive the clamping pieces 24 to adjust the arc based on the central position; the central position of the clamping pieces 24 is fixed through the end of the connecting plate 23; the clamping pieces 24 can adjust the arc, so as to increase the range of applicable parts; in addition, the staff can also replace the size of the clamping pieces 24.

[0023] The second connecting member is specifically a connecting spring 232; one end of the connecting spring 232 is fixedly connected to the output end of the second hydraulic cylinder 231, and the other end is fixedly connected to the clamping piece 24; when adjusting the arc of the clamping piece 24, the connection between the output end of the second hydraulic cylinder 231 and the clamping piece 24 is avoided through the connecting spring 232, so as to prevent interference during adjustment.

[0024] A pair of rectangular holes 211 are formed in the side surface of the support plate 21. A reinforcing rod 241 is inserted through the interior of the rectangular hole 211, and the end of the reinforcing rod 241 is fixedly connected to the side surface of the clamping piece 24. During the disassembly process, it may be necessary to fix the parts on the coupling. Therefore, the reinforcing rod 241 is provided. The reinforcing rod 241 is inserted into the rectangular hole 211, and the lateral moment received by the clamping piece 24 for clamping and fixing the parts can act directly on the support plate 21 through the clamping piece 24, the reinforcing rod 241, and the rectangular hole 211. Specifically, the clamping piece 24 presses the inner wall of the rectangular hole 211 through the reinforcing rod 241. Thereby, the connection between the clamping piece 24 and the support plate 21 is strengthened, preventing the connecting plate 23 from being damaged by excessive bending due to force. The diameter of the reinforcing rod 241 is the same as the lateral width of the rectangular hole 211, and the diameter of the reinforcing rod 241 is smaller than the longitudinal length of the rectangular hole 211. When adjusting the radian of the clamping piece 24, the reinforcing rod 241 is driven to swing up and down, and there is a gap reserved in the rectangular hole 211 to avoid interference.

[0025] A connecting block 27 is fixedly connected to the side surface of the support plate 21. A third hydraulic cylinder 271 is fixedly connected to the side surface of the connecting block 27. The output end of the third hydraulic cylinder 271 is fixedly connected to a connecting frame 272. The bottom end of the connecting frame 272 is fixedly connected to an insertion rod 273. The bottom end of the insertion rod 273 penetrates through the connecting block 27, and the bottom end of the insertion rod 273 is fixedly connected to a docking component. A plurality of docking grooves 4 are formed in the top end of the disassembly table 1 and are located below the docking component. The docking grooves 4 are adapted to the docking component. When fixing the position of the parts on the coupling, the third hydraulic cylinder 271 is started. The output end of the third hydraulic cylinder 271 drives the connecting frame 272 to move downward. The connecting frame 272 drives the insertion rod 273 to move downward. The insertion rod 273 drives the docking component to be inserted downward into the docking groove 4 at the top end of the disassembly table 1, thereby further strengthening the fixing effect of the support plate 21. Avoid providing fixation for the support plate 21 through the meshing between the gear 26 and the rack 3 to protect the motor 25. And the parts clamped and fixed by the clamping piece 24 maintain a good fixing effect, which is beneficial to the disassembly process.

[0026] The docking assembly includes a fixing frame 274, the top of which is fixedly connected to the bottom of the plug rod 273; the bottom of the fixing frame 274 is rotatably connected to a fixing block 275; the diameter of the fixing block 275 is the same as the inner diameter of the docking groove 4; a triangular block 41 is fixedly connected to the top of the disassembly platform 1 and located between the docking grooves 4; when the plug rod 273 drives the docking assembly to move downward, the fixing block 275 rotatably connected to the bottom of the fixing frame 274 moves downward synchronously, and when it is not aligned with the docking groove 4, as the fixing block 275 moves downward, the fixing block 275 moves downward. The bottom end of the fixed block 275 will contact the triangular block 41. The top of the triangular block 41 is set to a pointed end, and the bottom end of the fixed block 275 is set to a pointed end; therefore, the bottom end of the fixed block 275 will be offset from the top of the triangular block 41 and deflected, and then slide downward along the surface of the triangular block 41, and the bottom end of the triangular block 41 will dock with the notch of the docking groove 4; therefore, the fixed block 275 will be inserted into the docking groove 4 along the side of the triangular block 41, and then the fixation is completed; prevent the fixed block 275 from being interfered by the notch of the docking groove 4 during the insertion process of the docking groove 4.

[0027] The first connecting member includes a positioning plate 32, which is fixedly connected to the top of the disassembly platform 1; a buffer spring 31 is fixedly connected between the positioning plate 32 and the end of the rack 3; when the fixing block 275 is tilted and inserted into the docking groove 4, the docking groove 4 generates a lateral torque to the upper fixing frame 274 through the fixing block 275; the fixing frame 274 transmits the torque to the support plate 21 through the plug-in rod 273 and the connecting block 27, and the support plate 21 transmits the torque to the motor 25, and the motor 25 transmits the torque to the rack 3 through the gear 26. It should be pointed out that the torsion angle of the motor 25 is fixed at this point; therefore, the meshing position between the gear 26 and the rack 3 remains unchanged; when the rack 3 is subjected to torque, the buffer spring 31 at the end is squeezed and moves at the top of the disassembly platform 1; no interference will be generated; and the moving distance is short, which will not cause the gear 26 to be subjected to a large torsional torque.

[0028] A pair of limit blocks 276 are fixedly connected to the bottom end of the fixing frame 274 and on both sides of the rotation direction of the fixing block 275; the device of the limit blocks 276 prevents excessive shaking of the fixing block 275 when it moves, which makes it difficult to stably insert it into the docking groove 4 below when it stops.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
