Description

Technical Field

[0001] This utility model relates to the field of turbine compressor technology, and more specifically, to a turbine compressor turning tool. Background Technology

[0002] In offshore oil and gas production processes, turbine compressors are key equipment in natural gas processing, used for pressurizing and transporting natural gas. During annual turbine maintenance and in case of sudden malfunctions, endoscopic inspections of the turbine blades are necessary. This requires manual rotation of the turbine rotor components. The starter shaft of a turbine compressor typically has a groove on its end face. Current technology generally uses a metal plate inserted into this groove, along with an adjustable wrench for rotation. This method fails to ensure proper alignment and lacks axial support to guarantee tight contact between the metal plate and the groove. This allows the metal plate to easily slip out during rotation, causing hand injuries to workers and failing to meet the need for slow rotation during turbine endoscopic inspections. Furthermore, this technical solution relies almost entirely on manual rotation. The starting torque required during rotation is significant, making it difficult to control with an adjustable wrench, potentially leading to excessive rotation and exceeding the intended position, while also imposing a heavy workload on workers. Utility Model Content

[0003] To address the technical problems in existing turbine compressor turning operations, such as the inability to achieve proper alignment and the easy slippage of the metal plate from the slot, which could cause hand injuries to workers, this utility model provides a turbine compressor turning tool. This tool achieves stable alignment and torque transmission of the turbine compressor's drive shaft, ensuring the safety and accuracy of the turning operation and meeting the need for slow turning during turbine endoscopic examinations.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a turbine compressor turning tool, including a sleeve and a rotating shaft. The sleeve is a cylindrical structure with an open end and a closed end at its two ends. A rotating hole is formed at the center of the closed end. The rotating shaft is inserted into the rotating hole and rotatably connected to the sleeve. An insert is provided on the end face of the rotating shaft inserted into the sleeve, and a docking structure is provided on the end of the rotating shaft protruding from the closed end.

[0005] In this technical solution, the jacket is a hollow cylindrical structure with an open end and a closed end. The starting shaft of the turbine compressor can be inserted into the jacket through the open end, so that the jacket fits onto the starting shaft of the turbine compressor, and the jacket and the starting shaft are coaxial at this time. A rotating hole is formed at the center of the closed end of the jacket, and the rotating hole is located on the extension line of the axis of the starting shaft of the turbine compressor. Therefore, the rotating shaft installed in the rotating hole is also coaxial with the starting shaft of the turbine compressor. The rotating hole restricts the radial position of the rotating shaft, thus achieving stable alignment. Even if the rotating shaft is subjected to radial force, this force is transmitted to the jacket through the contact between the rotating shaft and the rotating hole, and ultimately to the starting shaft of the turbine compressor through the jacket. This maintains the relative radial stability of the starting shaft and the rotating shaft. The rotating hole supports the rotating shaft, ensuring that it remains concentric with the starting shaft during rotation, preventing torque fluctuations caused by misalignment, and meeting the requirements of slow and uniform rotation during endoscopic inspection. A insert is fixed to the end face of the rotating shaft that inserts into the jacket. The insert's shape matches the groove on the starting shaft of the turbine compressor, and it can be inserted into this groove. Since the radial position of the rotating shaft is fixed, the position of the insert on the rotating shaft will not change, ensuring precise alignment between the insert and the groove. Once the insert is inserted into the groove, the operator only needs to drive the rotating shaft to rotate, which in turn drives the insert and the starting shaft of the turbine compressor to rotate, thus achieving the rotation operation. The rotating shaft is equipped with a docking structure, which can be configured according to actual needs. Workers can connect the docking structure using tools such as wrenches and pry bars to drive the rotating shaft. Simultaneously, the docking structure can be connected to an external drive component, allowing the external drive component to automatically drive the rotating shaft without manual intervention, facilitating precise control of speed, torque, and rotation angle. The connection between the rotating shaft and the turbine compressor's starting shaft is surrounded by a jacket, which protects this connection from external objects that could interfere with the connection. Furthermore, the jacket is securely fitted onto the turbine compressor's starting shaft, ensuring a stable installation and preventing it from detaching and posing a safety hazard.

[0006] Preferably, the docking structure is a hexagonal head structure.

[0007] Preferably, a sliding bearing is also provided between the outer peripheral surface of the rotating shaft and the inner wall surface of the jacket.

[0008] Preferably, a limiting ring is provided on the outer circumferential surface of the rotating shaft, and the sliding bearing is installed between the limiting ring and the closed end.

[0009] Preferably, the closed end of the sleeve is further provided with an adjustment device for adjusting the depth of the rotating shaft inserted into the sleeve.

[0010] Preferably, the adjusting device includes an adjusting bolt and an adjusting plate. The adjusting plate is fixed on the rotating shaft and located inside the sleeve. A threaded hole is also provided on the closed end. The adjusting bolt is inserted into the sleeve through the threaded hole and abuts against the adjusting plate.

[0011] Preferably, the sleeve is further provided with a tightening device for tightening the open end.

[0012] Preferably, the tightening device includes a tightening groove, ear plates, and tightening bolts. The tightening groove is arranged along the length of the sleeve and extends through the inner and outer sides of the sleeve. The tightening groove is connected to the open end. The ear plates are provided with second threaded holes. At least two ear plates are provided, and the two ear plates are respectively arranged on both sides of the tightening groove. The tightening bolt passes through the second threaded holes on the two ear plates in sequence and is threadedly connected to the second threaded holes.

[0013] Preferably, the tightening device is provided in multiple circumferential directions on the outer wall surface of the jacket.

[0014] Preferably, the rotating shaft is a hollow cylindrical structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by restricting the radial movement of the rotating shaft with a sleeve, the rotating shaft and the starting shaft of the turbine compressor are ensured to be concentric, which improves the accuracy of docking and avoids torque fluctuations caused by misalignment. At the same time, the installation method of the sleeve ensures that the sleeve is installed firmly and is not easy to fall off, which improves safety. The sleeve protects the connection between the rotating shaft and the starting shaft of the turbine compressor. The rotating shaft is provided with a docking structure that can be connected to a wrench, pry bar or external driving component, which makes it convenient for the operator to drive the rotating shaft to rotate.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1As shown, a turbine compressor turning tool includes a sleeve 1 and a rotating shaft 2. The sleeve 1 is a cylindrical structure with an open end and a closed end at its two ends. A rotating hole 11 is formed at the center of the closed end. The rotating shaft 2 is inserted into the rotating hole 11 and rotatably connected to the sleeve 1. An insert 21 is provided on the end face of the rotating shaft 2 inserted into the sleeve 1, and a mating structure is provided on the end of the rotating shaft 2 protruding from the closed end. The sleeve 1 is a hollow cylindrical structure with an open end and a closed end at its two ends. The starting shaft of the turbine compressor can be inserted into the sleeve 1 through the open end, so that the sleeve 1 is fitted on the starting shaft of the turbine compressor, and the sleeve 1 and the starting shaft of the turbine compressor are coaxial at this time. The rotating hole 11 is formed at the center of the closed end of the sleeve 1. The rotating hole 11 is located on the extension line of the axis of the starting shaft of the turbine compressor. Therefore, the rotating shaft 2 installed in the rotating hole 11 is also coaxial with the starting shaft of the turbine compressor. The rotating hole 11 restricts the radial position of the rotating shaft 2, thus achieving stable alignment of the rotating shaft 2. Even if the rotating shaft 2 is subjected to radial force, this force is transmitted to the jacket 1 through the contact between the rotating shaft 2 and the rotating hole 11, and finally to the starting shaft of the turbine compressor through the jacket 1. This maintains the relative stability of the radial position of the starting shaft of the turbine compressor and the rotating shaft 2. The rotating hole 11 supports the position of the rotating shaft 2, ensuring that the rotating shaft 2 remains concentric with the starting shaft of the turbine compressor when rotating, avoiding torque fluctuations caused by misalignment, and meeting the requirements of slow and uniform rotation for endoscopic inspection. A insert 21 is fixed on the end face of the rotating shaft 2 that is inserted into the jacket 1. The shape of the insert 21 is the same as the shape of the slot on the starting shaft of the turbine compressor, and the insert 21 can be inserted into the slot. Since the radial position of the rotating shaft 2 is fixed, the position of the insert 21 on the rotating shaft 2 will not change, thus ensuring precise alignment between the insert 21 and the slot. Once the insert 21 is inserted into the slot, the operator only needs to drive the rotating shaft 2 to rotate. The rotating shaft 2 will then drive the insert 21, which in turn will drive the starting shaft of the turbine compressor to rotate, thus enabling the rotary operation. The rotating shaft 2 is equipped with a docking structure, which can be configured according to actual needs. The operator can use tools such as wrenches or pry bars to connect to the docking structure to drive the rotating shaft 2 to rotate. Simultaneously, the docking structure can be connected to an external drive component, allowing the external drive component to automatically drive the rotating shaft 2 without manual operation, facilitating precise control of speed, torque, and rotation angle. The connection between the rotating shaft 2 and the turbine compressor's starting shaft is surrounded by a sleeve 1, which protects this connection from external objects that could affect the connection between the rotating shaft 2 and the turbine compressor's starting shaft. Furthermore, the sleeve 1 is fitted onto the turbine compressor's starting shaft, ensuring a secure installation and preventing it from falling off and causing safety hazards.

[0021] like Figure 1As shown, the mating structure is a hexagonal head structure 22. The hexagonal head structure 22 is similar in shape to a regular bolt. Workers can use a wrench to connect with the hexagonal head structure 22 to drive the rotating shaft 2. Alternatively, a widely used electric screwdriver can be used, by replacing the connector on the electric screwdriver with an internal hexagon connector to match the hexagonal head structure 22, thereby driving the rotating shaft 2 to rotate.

[0022] like Figure 1 As shown, a sliding bearing 23 is also provided between the outer peripheral surface of the rotating shaft 2 and the inner wall surface of the jacket 1. The sliding bearing 23 supports the radial position of the rotating shaft 2, ensuring that the rotating shaft 2 will not deflect. At the same time, the sliding bearing 23 does not restrict the axial position of the rotating shaft 2, still preserving the axial movement freedom of the rotating shaft 2, so that the rotating shaft 2 can still be used to adjust the insertion depth in the jacket 1 to adapt to the starting shaft of turbine compressors of different specifications.

[0023] like Figure 2 As shown, a limiting ring 25 is provided on the outer circumferential surface of the rotating shaft 2, and the sliding bearing 23 is installed between the limiting ring 25 and the closed end. The limiting ring 25 is used to limit the position between the sliding bearing 23 and the rotating shaft 2, ensuring that the rotating shaft 2 does not disengage from the sliding bearing 23 due to excessive sliding during the installation of the sliding bearing 23 or during the sliding of the rotating shaft 2.

[0024] like Figure 2 As shown, the rotating shaft 2 is a hollow cylindrical structure. By making the rotating shaft 2 a hollow cylindrical structure, the weight of the rotating shaft 2 is reduced, while ensuring the integrity of its external structure, so that it can maintain sufficient strength to drive the rotation of the turbine compressor's starter shaft.

[0025] Example 2 This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, the closed end of the sleeve 1 is also provided with an adjustment device for adjusting the depth of the rotating shaft 2 inserted into the sleeve 1. The adjustment device is used to provide radial support for the rotating shaft 2 after it slides to the required position, thereby maintaining the positional stability of the rotating shaft 2 and preventing the insert 21 from being pulled out of the slot due to accidental movement of the rotating shaft 2 during subsequent turning processes, thus preventing the loss of the turning function.

[0026] like Figure 2As shown, the adjusting device includes an adjusting bolt 12 and an adjusting plate 24. The adjusting plate 24 is fixed on the rotating shaft 2 and is located inside the jacket 1. A threaded hole is also provided on the closed end. The adjusting bolt 12 is inserted into the jacket 1 through the threaded hole and abuts against the adjusting plate 24. In the initial state, the adjusting bolt 12 is screwed to the outermost position or unscrewed from the threaded hole to avoid interfering with the normal movement of the rotating shaft 2. After the rotating shaft 2 has slid to the desired position, the operator rotates the adjusting bolt 12 to insert it into the jacket 1 until one end of the adjusting bolt 12 inserted into the adjusting device abuts against the adjusting plate 24 located on the rotating shaft 2. This presses the rotating shaft 2 against the starting shaft of the turbine compressor, restricting the rotating shaft 2 from moving away from the starting shaft of the turbine compressor, and ensuring that the insert 21 will not be pulled out of the slot.

[0027] Example 3 This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, the jacket 1 is also equipped with a tightening device 3 for tightening the open end. The open end of the jacket 1 is connected to the starting shaft of the turbine compressor. By tightening the open end through the tightening device 3, the friction between the inner wall surface of the jacket 1 and the starting shaft of the turbine compressor can be increased, thereby fixing the jacket 1 more firmly on the starting shaft of the turbine compressor and ensuring that the jacket 1 will not fall off accidentally.

[0028] like Figure 2 , 4 As shown, the tightening device 3 includes a tightening groove 31, ear plates 32, and tightening bolts 33. The tightening groove 31 is arranged along the length of the jacket 1 and extends through both the inner and outer sides of the jacket 1. The tightening groove 31 is connected to the open end. The ear plates 32 have second threaded holes 34. There are at least two ear plates 32, which are respectively arranged on both sides of the tightening groove 31. The tightening bolts 33 pass through the second threaded holes 34 on the two ear plates 32 in sequence and are threadedly connected to the second threaded holes 34. The jacket 1 is made of a material with a certain degree of elasticity. The tightening groove 31 provides space for the tightening of the jacket 1. After the jacket 1 is fitted onto the starter shaft of the turbine compressor, the operator tightens the tightening bolts 33. As the tightening bolts 33 rotate, the two ear plates 32, which are threadedly connected to them through the second threaded holes 34, move closer to each other. At this time, the tightening groove 31 shrinks, which reduces the circumference of the open end of the jacket 1, thereby tightening the open end of the jacket 1 and making the jacket 1 clamp onto the starter shaft of the turbine compressor.

[0029] like Figure 1 As shown, multiple tightening devices 3 are arranged along the circumferential direction on the outer wall surface of the jacket 1. The tightening devices 3 will cause the jacket 1 to deform to a certain extent. Multiple tightening devices 3 are beneficial to disperse the deformation of the jacket 1 and avoid the deformation being too concentrated in a certain part of the jacket 1, which would cause structural damage.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
