[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] A sealing assembly disassembly device, such as Figure 1-Figure 6 As shown, it includes a mounting plate 1, a gripping handle 2, a gripping device 3, a plurality of telescopic arms 4 and a hydraulic telescopic rod 6. The mounting plate 1 is provided with a gripping handle 2, a plurality of telescopic arms 4 and a hydraulic telescopic rod 6. The plurality of telescopic arms 4 are symmetrically distributed on the outside of the hydraulic telescopic rod 6. The plurality of telescopic rods are movably arranged on the mounting plate 1. The hydraulic telescopic rod 6 is mounted on the mounting plate 1. The gripping handle 2 is sleeved on one end of the gripping device 3. The other end of the gripping device 3 is located in the mounting plate 1. The telescopic arm 4 is connected to the gripping device 3. A lubricating device 5 is provided in the mounting plate 1. The lubricating device 5 is connected to the telescopic arm 4. A pad 9 is provided on the outside of the telescopic arm 4. The pad 9 is a T-shaped cylinder. When the telescopic arm 4 cannot be embedded in the gap, a copper hammer can be used to knock on the pad 9 of the telescopic arm 4 to force it to be pushed into the gap between the fan and the gland to increase the gap between the two parts. The number of telescopic arms 4 is preferably Two, the ends of the telescopic arms 4 are sharpened and can be clamped by the gripping device 3, so that the end embedding amount is increased, and the lubricating oil mist is sprayed into the gap through the lubricating device 5 to increase the lubrication between the gland and the shaft, making it easier to disassemble the sealing device, so that the gap between the gland and the sealing flange is increased, and the gland is pulled out by multiple pulling. The gripping handle 2 is concave, and its two protruding parts are partially welded on the mounting disk 1, which is convenient for the operator to hold the entire device firmly. A pull cover 10 is provided on the upper surface of the mounting disk 1. The pull cover 10 avoids the gripping device 3 and is connected to the mounting disk 1. A card interface is provided on the mounting disk 1. The hydraulic telescopic rod 6 lightly presses the gland to assist the disassembly process. The telescopic arm 4 passes through the mounting disk 1. When the gripping device 3 is driven, the mounting disk 1 applies a vertical limiting resistance force to the telescopic arm 4, so that the telescopic arm 4 moves horizontally.

[0031] The gripping device 3 includes a grip 31, a transmission member 32 and a spring column 33. The grip 31 is connected to the telescopic arm 4 through the transmission member 32. The sleeve end of the grip 31 is connected to the grab 2 through the spring column 33. The grip 31 is movably installed in the grab 2.

The grip 31 is convex, and the transmission member 32 is installed on the protruding edge and connected to the two telescopic arms 4, converting the vertical upward force into a horizontal force for inward clamping. The buffer force is applied by the spring column 33 to prevent the clamping speed from being too fast, which may cause damage to the device. When the grip 31 moves, the spring column 33 will be compressed, thereby generating a buffer force, which helps to slow down the clamping speed and prevent damage to the device due to excessive clamping speed.

[0032] The telescopic arm 4 includes a first mechanical arm 41, a second mechanical arm 42 and a locking bolt 43. The first mechanical arm 41 is sleeved on the second mechanical arm 42. The first mechanical arm 41 and the second mechanical arm 42 are both provided with corresponding threaded holes. The second mechanical arm 42 is fixedly connected to the first mechanical arm 41 through the locking bolt 43. The first mechanical arm 41 is movably mounted on the mounting plate 1 through the gripping device 3. A pad 9 is provided on the outer side of the second mechanical arm 42. The length of the telescopic arm 4 can be flexibly adjusted as needed, which effectively improves the adaptability of the device. The first mechanical arm 41 and the second mechanical arm 42 are fastened and connected through the corresponding threaded holes by the locking bolt 43, which ensures the stability and reliability of the telescopic arm 4 in the extended or contracted state. The mechanical connection method is simple and effective. It can withstand a large workload, reduce safety risks caused by looseness or breakage, and facilitate subsequent maintenance. The pad 9 is installed on the outside of the second mechanical arm 42. When struck with a copper hammer, it is convenient to apply force to the inner gap at the sharpened point of the second mechanical arm 42. The first mechanical arm 41 and the second mechanical arm 42 are both provided with lubrication holes, which are connected to the lubrication device 5.

A stabilizing support rod 11 is installed on the inner side of the corner of the first mechanical arm 41 and the inner side of the corner of the second mechanical arm 42. The stabilizing support rod 11 provides auxiliary support for the mechanical arm, enhances the overall stability of the mechanical arm, and prevents deformation or damage under heavy loads or high-speed movement, thereby improving the load-bearing capacity and working stability of the telescopic arm 4.

[0033] The lubrication device 5 includes an oil pump 51 and an oil pipe 52. The oil pump 51 is connected to the telescopic arm 4 through the oil pipe 52. The oil pipe 52 runs through the lubrication through hole. The lubricating oil is driven by the oil pump 51 and is sprayed at high pressure to the contact surface between the shaft and the sealing assembly through the oil pipe 52. The lubricating oil can be quickly delivered to the key parts that need lubrication, thereby increasing the lubrication between the gland and the shaft.

[0034] A hydraulic cylinder 7 is provided in the mounting plate 1, and the hydraulic cylinder 7 drives the hydraulic telescopic rod 6. A suction cup 8 is installed on the telescopic end of the hydraulic telescopic rod 6. The hydraulic cylinder 7 drives the hydraulic telescopic rod 6 to perform telescopic adjustment. The suction force between the suction cup 8 and the gland surface is utilized in cooperation with the telescopic arm 4 to increase the gap between the gland and the sealing flange. The gland is pulled out by repeated pulling.

[0035] The parts and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

[0036] Working principle: When removing the sealing assembly, first pull the sharpened end of the telescopic arm 4 to press against the gap between the gland and the sealing flange by adjusting the length, adjust the hydraulic telescopic rod 6 by the hydraulic cylinder 7 until the appropriate distance, suck the suction cup 8 at the end onto the surface of the gland, hold the handle 31 by hand to pull, and the transmission member 32 in the mounting plate 1 drives the telescopic arm 4 to retract inward. At this time, the end of the arm is embedded in the gap, and at the same time, the end of the telescopic arm 4 sprays high-pressure lubricating oil mist through the oil pipe 52 in the lubrication through hole to increase the lubrication between the gland and the shaft, making it easier to remove the sealing device;

[0037] Hold the pull rod several times to increase the embedding amount of the end of the telescopic arm 4, use the suction force of the suction cup 8 and the gland surface to increase the gap between the gland and the sealing flange, pull the gland several times to pull it out. If the telescopic arm 4 cannot be smoothly embedded in the gap, use a copper hammer to knock on the pads 9 outside the two telescopic arms 4, and the telescopic arm 4 is forced to embed into the inner gap.
