Description

Technical Field

[0001] This utility model relates to the field of compensation equipment technology, and in particular to a hydraulic puller compensator. Background Technology

[0002] In motor maintenance, removing components such as bearings, fans, and couplings from both sides of the motor is a common and crucial step. Currently, hydraulic pullers are typically used to remove these components.

[0003] In practical use, traditional hydraulic pullers have many drawbacks. When the motor shaft is long, ordinary hydraulic pullers cannot remove the coupling wheel at once, requiring additional shims such as screws and cylindrical iron bars. This not only increases the number of steps, requiring three people to operate the process instead of two, thus increasing labor costs, but also requires operators to prevent the shims from shifting during the shim installation process, which increases the complexity and difficulty of the operation. Furthermore, the instability of the hydraulic puller and the shims during operation poses a safety hazard of the puller falling off and injuring people. To solve these problems, this utility model provides a hydraulic puller compensator. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic puller compensator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic puller compensator includes a support rod and a hydraulic puller connecting end. The lower end of the hydraulic puller connecting end has a threaded hole for installation. The upper end of the support rod has an anti-slip groove. An installation bolt is fixedly connected inside the anti-slip groove. A bearing is fixedly connected to the lower end of the support rod. A transmission rod is rotatably connected inside the bearing. An adjusting nut is fixedly connected to the lower end of the transmission rod. An adjusting threaded rod is fixedly connected to the lower end of the adjusting nut. An adjusting rod is threaded onto the surface of the adjusting threaded rod.

[0007] As a further improvement of this utility model, a connecting block is fixedly connected to the lower end of the adjusting rod.

[0008] As a further improvement of this utility model, lower mounting blocks are fixedly connected to both sides of the connecting block, and a sleeve rod is fixedly connected to the upper end of the lower mounting block.

[0009] As a further improvement of this utility model, upper mounting blocks are fixedly connected to both sides of the lower end of the support rod, and a limiting rod is fixedly connected to the lower end of the upper mounting block. The limiting rod is movably connected to the sleeve rod.

[0010] As a further improvement of this utility model, a top block is fixedly connected to the lower end of the connecting block, and the surface of the top block is provided with anti-slip texture.

[0011] As a further improvement of this utility model, the lower end of the hydraulic puller connection is fixedly connected with an anti-slip ring adapted to the anti-slip groove, and the anti-slip ring is made of rubber.

[0012] The beneficial effects of this utility model are:

[0013] By setting an adjusting rod, during use, rotating the adjusting nut drives the transmission rod to rotate, which in turn causes the adjusting threaded rod to rotate. As the adjusting threaded rod rotates, the adjusting rod can move up and down along its surface, realizing flexible adjustment of the compensator top rod length. This allows the hydraulic puller compensator to quickly and accurately adapt to motor shafts of different lengths according to actual operation needs, without the need to change additional tools or equipment, thus improving the versatility and practicality of the tool and meeting diverse operation requirements.

[0014] By setting a limit rod, during use, the limit rod moves inside the sleeve rod during the movement of the adjusting rod, ensuring that the adjusting rod can only move along the axial direction of the adjusting threaded rod and will not deviate. This allows the operator to more accurately control the length of the compensator top rod, improves work efficiency, reduces the time wasted due to repeated adjustments, and ensures the safety and efficiency of the operation.

[0015] By setting an anti-slip ring, during use, the hydraulic puller compensator is installed onto the hydraulic puller connection end through the mounting bolt in the anti-slip groove. After the mounting bolt is fully screwed into the mounting thread hole, the anti-slip ring at the hydraulic puller connection end enters the anti-slip groove simultaneously. The anti-slip ring and the anti-slip groove fit tightly together, effectively preventing the mounting bolt from loosening during operation, so that the compensator and the hydraulic puller can maintain a stable connection.

[0016] In summary, this utility model enables flexible adjustment of the length of the hydraulic puller rod, meeting the disassembly requirements of different motor equipment components, while ensuring the safety and efficiency of the operation process. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 The hydraulic puller compensator includes a support rod 1 and a hydraulic puller connection end 2. The lower end of the hydraulic puller connection end 2 is provided with a threaded hole 3. The upper end of the support rod 1 is provided with an anti-slip groove 4. An installation bolt 5 is fixedly connected inside the anti-slip groove 4. A bearing 6 is fixedly connected to the lower end of the support rod 1. A transmission rod 7 is rotatably connected inside the bearing 6. An adjusting nut 8 is fixedly connected to the lower end of the transmission rod 7. An adjusting threaded rod 9 is fixedly connected to the lower end of the adjusting nut 8. An adjusting rod 10 is threadedly sleeved on the surface of the adjusting threaded rod 9.

[0023] In this utility model, a connecting block 11 is fixedly connected to the lower end of the adjusting rod 10, and lower mounting blocks 12 are fixedly connected to both sides of the connecting block 11. A sleeve rod 13 is fixedly connected to the upper end of the lower mounting block 12. The sleeve rod 13 provides space and guidance for the movement of the limiting rod 15, so that the limiting rod 15 can move inside it according to a predetermined trajectory, ensuring the accuracy and stability of the adjustment process. Upper mounting blocks 14 are fixedly connected to both sides of the lower end of the support rod 1, and the limiting rod 15 is fixedly connected to the lower end of the upper mounting block 14. The limiting rod 15 is movably connected to the sleeve rod 13. The limiting rod 15 moves precisely inside the sleeve rod 13, playing a guiding and limiting role, ensuring that the adjusting rod 10 can only move in a predetermined direction, and avoiding deviation and shaking during the adjustment process.

[0024] A top block 16 is fixedly connected to the lower end of the connecting block 11. The surface of the top block 16 is provided with anti-slip texture. The anti-slip texture increases the friction between the top block 16 and the equipment to be disassembled. During operation, it can effectively prevent relative sliding between the top block 16 and the equipment, ensuring effective force transmission, improving the stability and reliability of the disassembly operation, and reducing the risk of operation failure due to slippage. An anti-slip ring 17 that matches the anti-slip groove 4 is fixedly connected to the lower end of the hydraulic puller connecting end 2. The anti-slip ring 17 is made of rubber. The matching design between the anti-slip ring 17 and the anti-slip groove 4 makes the connection between the hydraulic puller connecting end 2 and the support rod 1 tighter and more stable. During installation, the anti-slip ring 17 can smoothly enter the anti-slip groove 4 and fit tightly with the anti-slip groove 4, effectively preventing the installation bolt 5 from loosening during use and ensuring the reliability of the entire hydraulic puller compensator and hydraulic puller connection.

[0025] In use, this invention first installs the device onto the hydraulic puller connection end 2 using the mounting bolts 5 of the anti-slip groove 4. After the mounting bolts 5 are fully inserted into the mounting threaded holes 3 of the hydraulic puller connection end 2, the anti-slip ring 17 of the hydraulic puller connection end 2 will also enter the anti-slip groove 4. The cooperation between the anti-slip ring 17 and the anti-slip groove 4 can prevent the mounting bolts 5 from loosening, making the hydraulic puller compensator and the hydraulic puller a whole. When it is necessary to adjust the length of the hydraulic puller compensator push rod according to the length of the disassembled motor shaft, the operator rotates the adjusting nut 8 to drive the transmission rod 7 to rotate. As the transmission rod 7 rotates, the adjusting threaded rod 9 rotates accordingly, causing the adjusting rod 10 to move up and down along the surface of the adjusting threaded rod 9. This allows for the adjustment of the length of the compensator top rod, meeting the dismantling requirements of equipment components such as motor couplings, bearings, and fans of different lengths. During the movement of the adjusting rod 10, the limiting rod 15 moves inside the sleeve rod 13, serving as a guide and limiter to ensure that the adjusting rod 10 can only move axially along the adjusting threaded rod 9 without deviation. After the length is adjusted, the hydraulic puller compensator is connected to the equipment to be dismantled.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
