Description

Technical Field

[0001] This utility model relates to the field of maintenance and disassembly equipment technology, specifically a hydraulic coupling maintenance and disassembly device. Background Technology

[0002] A hydraulic coupling, also known as a hydraulic connection, is a mechanical device used to connect a power source (usually an engine or motor) to a working machine to transmit rotational power. It was once used in automatic transmissions in automobiles and also has wide applications in marine and heavy industries.

[0003] For example, utility model patent CN219704971U discloses a hydraulic coupler maintenance and disassembly device, which relates to the field of maintenance and disassembly equipment technology, specifically a hydraulic coupler maintenance and disassembly device, including a lifting component and a disassembly component mounted thereon; through the setting of the disassembly component, the hydraulic coupler maintenance and disassembly device has the effect of disassembling the hydraulic coupler, connecting the connecting seat to the external thread of the hydraulic coupler, that is, externally fixing the connecting seat to the hydraulic coupler, so that the weight of the hydraulic coupler itself is distributed from the force on the motor output shaft to the hydraulic coupler maintenance and disassembly device; then the internal thread of the hydraulic coupler and the motor output shaft is removed, so that the hydraulic coupler and the motor are connected. Separating the output shaft, i.e., removing the hydraulic coupler, protects the internal threading and prevents damage to the equipment during removal, thus reducing maintenance costs and improving the integrity of the removed equipment. However, there are problems such as the hydraulic coupler being unsupported after threading removal, and the need to manually rotate the connecting seat during removal. This results in time-consuming and laborious threading removal, poor support of the hydraulic coupler, and ultimately, a long time to remove the threading and the possibility of the hydraulic coupler suddenly detaching from the connecting seat, reducing safety. To address these issues, we propose a hydraulic coupler maintenance and removal device. Utility Model Content

[0025] Specifically, the hydraulic coupling adjustment assembly 5 can supply power to the stepper motor 59, the first electric push rod 51, and the second electric push rod 54 via an external power source. The output of the first electric push rod 51 drives the horizontal plate 52 to rise, while the output of the second electric push rod 54 drives the pinion 55 to move. During this process, the output of the stepper motor 59 drives the second rotating shaft 58 to rotate, which in turn drives the large gear 57 to rotate. The large gear 57 then drives the pinion 55 to rotate, which in turn drives the first rotating shaft 56 to rotate.

During this process, the fixing plate 62 can be operated using the L-shaped handle 65. The hydraulic coupling assembly 7 indirectly exerts pressure on the support spring 61. Then, each threaded section 74 can be removed through the locking screw hole 511. When the angle of the hydraulic coupling assembly 7 needs adjustment, power can be supplied to the stepper motor 59, the first electric push rod 51, and the second electric push rod 54 via an external power source. The output of the first electric push rod 51 then drives... When the horizontal plate 52 rises, the output end of the second electric push rod 54 drives the small gear 55 to move. During this process, the output end of the stepper motor 59 drives the second rotating shaft 58 to rotate, which in turn drives the large gear 57 to rotate. The large gear 57 drives the small gear 55 to rotate, which in turn drives the first rotating shaft 56 to rotate. The first rotating shaft 56 drives the mounting plate 510 to rotate, which in turn drives the hydraulic coupling assembly 7 to adjust its angle. During the angle adjustment of the hydraulic coupling assembly 7, the follower wheel 67 rotates. This utility model enables the hydraulic coupling body 71 to be supported when the threaded section 74 is removed, preventing the hydraulic coupling body 71 from falling and improving safety.
