Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a hydraulic coupler disassembly tool. Background Art

[0002] In modern industrial production, hydraulic couplings, as a key device for transmitting mechanical power, are widely used in various mechanical transmission systems, such as power transmission systems, large vehicles and various industrial machinery. Hydraulic couplings can effectively alleviate the impact load during the startup process and improve the stability and efficiency of the transmission system. However, with the widespread application of hydraulic couplings in industry, the complexity and labor intensity of their maintenance and disassembly work have gradually increased. Especially when repairs or replacements are required, traditional disassembly tools often cannot meet the needs of fast and safe disassembly.

[0003] Traditional methods of disassembling hydraulic couplers usually rely on hand tools or simple mechanical equipment such as wrenches and crowbars, which are not only labor-intensive but also inefficient. In addition, improper operation can easily lead to damage to the coupler or related equipment, and may even cause safety accidents, resulting in unnecessary economic losses and personal injuries. At the same time, in many industrial environments, the location of the hydraulic coupler may be in a difficult-to-reach area of ​​the machine, which increases the difficulty of disassembly. Therefore, operators need to spend a lot of time and energy to adapt to different working environments during the disassembly process and try to use a variety of different tools to complete the task.

[0004] In view of this, there is an urgent need for a hydraulic coupler disassembly tool that greatly improves work efficiency and reduces the time and labor required for disassembly. Utility Model Content

[0005] The utility model aims to provide a hydraulic coupling disassembly tool to solve the problem that traditional disassembly tools in the prior art often fail to meet the requirements of rapid and safe disassembly.

[0006] The utility model is realized through the following technical scheme: a hydraulic coupler disassembly tool comprises a shell, a joint and a pull tube, a hydraulic jack is arranged inside the shell, and the hydraulic jack is connected to the joint through a push rod; the joint is detachably connected to the pull tube; an electric hydraulic pump connected to the hydraulic jack is arranged outside the shell.

[0007] Preferably, it also includes an oil joint slide, which is arranged on the hydraulic jack and connected to the jack rod.

[0008] Preferably, it further comprises a rotating screw, which is arranged on one side of the housing and connected to the hydraulic jack.

[0009] Preferably, the electric hydraulic pump is connected to the hydraulic jack via a hydraulic oil pipe.

[0010] Preferably, the top rod is a round steel tube with a diameter of 30 mm.

[0011] Preferably, the length of the push rod is 570 mm, 710 mm and 850 mm.

[0013] Preferably, the thread sizes of the pull tube are M36, M40, M42, M48, M50, M55, M56, M60, and M64, respectively.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The power support of the electric hydraulic pump can provide a strong jacking force, which enables the hydraulic coupler to be removed quickly and smoothly, greatly improving work efficiency and reducing the time and labor required for disassembly.

[0016] During the disassembly process, the hydraulic energy generated by the electric hydraulic pump can stably and continuously assist the hydraulic jack to work, ensuring that the disassembly force is uniform and continuous, thereby avoiding equipment damage or operator safety accidents caused by improper force.

[0017] Through the detachable joint and the pull tube, the tool can be adapted to hydraulic couplers of different sizes.

[0022] The present invention is further described in conjunction with specific embodiments, but is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0023] refer to Figure 1-3 As shown, the utility model provides a hydraulic coupler disassembly tool, wherein A in the figure is a local hydraulic coupler, B is the shaft of the hydraulic coupler, and the disassembly tool includes a shell 9, a joint 1 and a pull tube 8, a hydraulic jack 3 is arranged inside the shell 9, and the hydraulic jack 3 is connected to the joint 1 through a push rod 2; the joint 1 is detachably connected to the pull tube 8; and an electric hydraulic pump 7 connected to the hydraulic jack 3 is arranged outside the shell 9. In this embodiment, the connector 1 is responsible for connecting the pull tube 8 of corresponding size, and is connected with the pull tube 8 by docking and rotating. The hydraulic jack 3 is a 50t hydraulic jack with a stroke of 60mm. In conjunction with the electric hydraulic pump, it can provide a strong jacking force, so that the hydraulic coupler can be smoothly and quickly disassembled, ensuring the efficiency and safety of the disassembly process; during the working process, the electric hydraulic pump 7, the electric hydraulic pump 7 generates liquid energy to assist the hydraulic jack 3 in working, and after the connector 1 is rotated and spliced ​​with the pull tube 8, it is installed on the hydraulic coupler that needs to be disassembled, and the hydraulic jack 3 supports the push rod 2, so that the hydraulic coupler can be disassembled smoothly; during the disassembly work, the push rod 2 and the hydraulic coupler present a reaction force, thereby removing the hydraulic coupler from the shaft.

[0024] It also includes an oil joint slide 4, which is arranged on the hydraulic jack 3 and connected to the jack 2; when in use, the oil joint slide 4 can assist the hydraulic jack 3 to move up and down smoothly; the oil joint slide 4 helps the hydraulic jack 3 to move more smoothly and stably in the vertical direction, reduces equipment damage or safety accidents caused by improper operation, and increases the accuracy of operation.

[0025] It also includes a rotating screw 5, which is arranged on one side of the shell 9 and connected to the hydraulic jack 3. When in use, the rotating screw 5 can maximize the stroke of the hydraulic jack 3. After the hydraulic jack 3 has reached its maximum stroke, the pressure is released and the rotating screw 5 is rotated to allow the hydraulic jack 3 to continue to work effectively. The setting of the rotating screw 5 allows the hydraulic jack 3 to be adjusted by rotation after reaching the maximum stroke, and to be reused, thereby increasing the use efficiency and working flexibility of the hydraulic jack 3.

[0026] The electric hydraulic pump 7 is connected to the hydraulic jack 3 via a hydraulic oil pipe 6 , thereby facilitating the hydraulic energy generated by the electric hydraulic pump 7 to assist the hydraulic jack 3 in its operation.

[0027] The diameter of the push rod 2 is a round steel tube of 30 mm; the lengths of the push rod 2 are 570 mm, 710 mm and 850 mm. Since the stroke of the hydraulic jack 3 is limited, the three lengths of the push rods 2 are mainly used to cooperate with the disassembly of the hydraulic coupler and the shaft during disassembly.

[0028] The thread sizes of the pull tube 8 are respectively M36, M40, M42, M48, M50, M55, M56, M60 and M64. The nine thread sizes of the pull tube 8 can be used in conjunction with 95% of the hydraulic coupler models. They are widely used in the disassembly of hydraulic couplers of different sizes and types, greatly improving the applicability and flexibility of the tool.
