Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly to a quick disassembly and assembly connection component for a shaft generator of a container ship. Background Art

[0002] During the operation of a container ship, the shaft generator, as a key power supply device, requires frequent maintenance and repair work. Due to the complex ship operation environment, the shaft generator often needs to be quickly disassembled and assembled for maintenance due to mechanical wear, electrical faults, etc., to ensure the stable operation of the ship's power system and reduce the economic losses caused by the downtime. The traditional shaft generator is connected to related ship components through a flange connection component, which exposes many deficiencies in frequent disassembly and assembly operations.

[0003] In the prior art, when installing a shaft generator, the alignment and leveling of the two flange plates mostly rely on manual operation, with low efficiency and difficult to guarantee accuracy. Crew members need to spend a lot of time adjusting the flange position based on experience, which not only consumes manpower and material resources, but also easily causes installation errors due to human factors. For example, in the narrow engine room space, it is inconvenient for workers to operate, and it is difficult to ensure that the two flange plates are completely concentric and flat. This will cause uneven stress on the connecting bolts. During the ship's navigation, due to factors such as hull vibration and equipment vibration, the bolts are prone to loosen or even break, seriously affecting the operation stability of the shaft generator and increasing potential safety hazards.

[0004] Moreover, for the bolts of the flange connection component, the prior art lacks real-time and effective means for monitoring loosening. Usually, only regular manual inspections can be carried out to visually observe or use simple tools to detect whether the bolts are loose. This method cannot detect the subtle loosening of the bolts caused by factors such as vibration and temperature change during the ship's operation in a timely manner. Once the loosening of the bolts is not discovered in time, as the ship continues to operate, the loosening intensifies, which will cause the sealing of the flange connection surface to fail, resulting in oil leakage and air leakage phenomena, affecting the normal operation of the shaft generator and even triggering serious equipment failures. At the same time, when it is found that the bolts are loose, they need to be tightened one by one manually, which is cumbersome to operate. And in case of an emergency, it is impossible to respond quickly for tightening treatment, delaying the repair opportunity.

[0005] Therefore, the present invention proposes a quick disassembly and assembly connection component for a shaft generator of a container ship to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a quick disassembly and assembly connection assembly for a shaft generator of a container ship, which has the following beneficial effects: 1. By setting up the auxiliary disassembly and leveling mechanism, the shaft-belt generator body is placed in the approximate position. Under the deflection control of the toggle lever, the auxiliary spring body and the triangular plate are used in cooperation with each other to make the centering body fit with the outer ring of the first flange and the second flange connection surface. Under the setting of the three centering bodies, the first flange and the second flange are evenly stressed on the circumference, and the axis is precisely aligned. The first flange on the shaft-belt generator body and the second flange of the connecting assembly are quickly and accurately positioned concentrically, thereby improving assembly efficiency, reducing downtime for transmission maintenance or equipment replacement, further reducing manual alignment errors and labor intensity of operation, improving assembly accuracy, and facilitating auxiliary installation in container ships with limited space, so as to better ensure the stability and reliability of the shaft-belt generator body during operation.

[0017] 2. Through the auxiliary support of the centering body to the first flange and the second flange on the shaft-driven generator body, after precise centering, the connection between the first flange and the second flange is tighter and more stable, and under the release of the elastic potential energy stored in the auxiliary spring body, the auxiliary centering body always fits the circumferential surface of the first flange and the second flange evenly and tightly.

[0018] 3. Through the setting of strain gauges, the state changes of the nut can be sensed in real time. When the nut becomes loose, the strain gauge converts the mechanical strain into an electrical signal and feeds it back to the monitoring system. The loosening of the nut can be discovered at the first time, and timely measures can be taken to avoid more serious problems caused by the supported fixture. Moreover, it is installed on the nut without direct contact with other components. The non-contact measurement method will not cause additional interference or impact on the connection structure of the nut and the first flange and the second flange, thereby ensuring the integrity and stability of the connection structure under normal working conditions. It is also easier to integrate with the detection system, and it is convenient to form a sensor network with multiple strain gauges to conduct comprehensive detection of the entire connection, realize automatic fault diagnosis and feedback, and thus control the stable progress of the next operation.

[0019] 4. Through the setting of the anti-loosening fastening mechanism, when the nut is loosened and with the feedback of the strain gauge, the driving screw is controlled to rotate forward, so that the expansion disk contacts the expansion body surface, moves toward the outer circle of the bolt to expand the bolt diameter, and the tightness of the connection between the first flange and the second flange is improved, which effectively prevents relative displacement or loosening between the first flange and the second flange, ensures the firm connection between the shaft-driven generator body and related components, ensures the stability of the equipment during operation, reduces the safety hazards caused by loose connection, ensures the power supply and overall operation safety of the ship, reduces the risk of equipment failure or accidents caused by loose bolts and nuts, and starts and adjusts in real time according to the loose situation without frequent manual inspection and tightening. This automatic compensation function can respond to emergencies in a timely manner and ensure the reliability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

The auxiliary disassembly and leveling mechanism 2 includes a built-in ring 21, which is mainly used to assist in the positioning of the auxiliary disassembly and leveling mechanism 2. The built-in ring 21 is slidably sleeved with the outer ring of the first flange 11. The outer ring of the built-in ring 21 is symmetrically provided with two positioning rods 22 with the axis as the center line. A toggle rod 23 is fixedly connected to one side of the outer ring of the built-in ring 21. The toggle rod 23 is mainly used to control the rotation of the built-in ring 21. The outer ring of the built-in ring 21 is slidably sleeved with a sleeve ring 24, and a sliding groove is opened on one side of the sleeve ring 24. The toggle rod 23 is slidably connected in the sliding groove opened on the sleeve ring 24. The outer ring of the sleeve ring 24 is symmetrically opened with arc grooves 25, and columns are fixedly connected in the two arc grooves 25. The positioning rods 22 on both sides of the built-in ring 21 are respectively located in the arc grooves 25 opened on the sleeve ring 24. An auxiliary spring body 26 is fixedly connected to the positioning rod 22.

The first fixed axis 28, the second deflection axis 29 and the centering body 210 are respectively located at the three corners of the triangular plate 27.

[0025] For further examples, please refer to Figures 6 to 10 As shown: The anti-loosening fastening mechanism 3 is used to assist the first flange 11 and the second flange 13 to be firmly connected during use to prevent external factors from causing them to loosen. The anti-loosening fastening mechanism 3 also includes a bolt 31, which is threadedly connected to the first flange 11, the sealing gasket 12 and the second flange 13. Six bolts 31 are equidistantly arranged around the center of the second flange 13. Nuts 32 are threadedly connected to both ends of the bolt 31. A strain gauge 33 is fixedly connected to one side of the two nuts 32 close to the second flange 13. The strain gauge 33 is electrically connected to an external controller. A movable inner Cavity 34, a through slot 35 is provided on the bolt 31 of the outer ring of the movable inner cavity 34, and four through slots 35 are equidistantly provided around the axis of the bolt 31, and expansion bodies 36 are clamped in the four through slots 35. The expansion body 36 is mainly used for the change of its strain when the nut 32 is loosened, thereby causing the change of the resistance value of the strain gauge 33, and then after being processed by the conversion circuit, the feedback is fed back to the external controller, and then the expansion degree of the expansion body 36 is adjusted to assist the stability of the connection of the bolt 31. Both ends of the expansion body 36 are slidably connected to the bolt 31, and the expansion body 36 is a right-angled triangle and a thread is fixedly connected on the right-angle surface to match the thread on the outer surface of the bolt 31; The anti-loosening fastening mechanism 3 also includes a driving screw 37, which is mainly used for rotating forward and reverse to drive the expansion disk 38 to move back and forth thereon to control the outward expansion and resetting of the expansion body 36. The driving screw 37 is electrically connected to an external controller, and the driving screw 37 is rotationally connected to the movable inner cavity 34. The driving screw 37 has a built-in driving source, and both ends of the driving screw 37 are rotationally connected to the inner surface of the bolt 31 respectively. The outer ring of the driving screw 37 is fixedly connected to the expansion disk 38, and the expansion disk 38 is composed of three disks of different diameters. The three disks of the expansion disk 38 have the same spacing, and a connecting rod 39 is fixedly connected between the expansion disks 38.

[0026] Everything in the above example works like this: In the initial state: the bolt 31 is not inserted into the first flange 11, the sealing gasket 12 and the second flange 13, the auxiliary spring body 26 is in a relaxed state, the toggle rod 23 is not pushed and deflected, the centering body 210 does not interfere with the connection between the first flange 11 and the second flange 13, and the expansion disk 38 is at the end away from the driving screw 37.

[0027] The following is the working process of the auxiliary disassembly and leveling mechanism 2 for assisting the positioning of the first flange 11 and the second flange 13 on the shaft-driven generator body 1 during installation and for the quick centering operation to align the axes of the first flange 11 and the second flange 13: During use, the operator uses a hoisting device to lift the shaft generator body 1 to a position near the installation location. Then, the first flange 11 on the shaft generator body 1 is roughly aligned with the second flange 13, and the gasket 12 is fitted and connected to the first flange 11. At this time, the operator pushes the toggle lever 23 to deflect reversely within the socket ring 24. During the reverse deflection process, the positioning rods 22 symmetrically arranged on the outer ring of the inner ring 21 slide reversely in the arc grooves 25 synchronously. At this time, the auxiliary spring body 26 is compressed to store elastic potential energy. Furthermore, since the second deflecting shaft 29 is connected to the inner ring 21, when the inner ring 21 deflects, the second deflecting shaft 29 synchronously deflects reversely with the center of the inner ring 21 as the axis. And under the limiting effect of the connection between the first fixed shaft 28 and the socket ring 24, the centering body 210 deflects towards the outer ring of the inner ring 21, causing the three centering bodies 210 to move away from the axis of the inner ring 21, completing the installation preparation work; Further, the first flange 11 and the second flange 13 on the shaft generator body 1 are brought closer. At this time, the operator pushes the toggle lever 23 to deflect forward. During the forward deflection process, the second deflecting shaft 29 synchronously deflects with the forward deflection of the inner ring 21, so that the triangular plate 27 rotates with the first fixed shaft 28 as the axis, driving the centering body 210 to deflect towards the center of the inner ring 21 until the centering body 210 gradually fits with the connection surfaces of the first flange 11 and the second flange 13. And under the release of the elastic potential energy stored in the auxiliary spring body 26, the tightness of the connection surface between the centering body 210 and the second flange 13 is squeezed. With the assistance of the three centering bodies 210, the circumference of the connection between the first flange 11 and the second flange 13 is evenly grasped, realizing rapid centering, ensuring the precise alignment of the axis of the shaft generator body 1 and the second flange 13, thereby completing the auxiliary positioning work for the installation of the first flange 11 and the second flange 13; Through the setting of the auxiliary disassembly and leveling mechanism 2, the shaft generator body 1 is placed in a rough position. Under the deflection control of the toggle lever 23, it cooperates with the auxiliary spring body 26 and the triangular plate 27, so that the centering body 210 fits with the outer rings of the connection surfaces of the first flange 11 and the second flange 13. With the setting of the three centering bodies 210, the circumferences of the first flange 11 and the second flange 13 are evenly stressed, the axes are precisely aligned, and the first flange 11 on the shaft generator body 1 and the second flange 13 of the connection assembly are concentrically positioned quickly and accurately, improving the assembly efficiency, reducing the downtime for ship maintenance or equipment replacement, further reducing the error of manual alignment and the labor intensity of operation, improving the assembly accuracy, facilitating the auxiliary installation in a container ship with limited space, and better ensuring the stability and reliability of the shaft generator body 1 during operation.

[0028] Further, through the auxiliary support of the middle body 210 for the first flange 11 and the second flange 13 on the shaft generator body 1, after precise centering, the connection between the first flange 11 and the second flange 13 is tighter and more stable. And under the release of the elastic potential energy stored in the auxiliary spring body 26, the auxiliary centering body 210 always evenly and tightly fits the circumferential surfaces of the first flange 11 and the second flange 13. During the operation of the container ship, it can better withstand the forces generated by factors such as hull shaking and equipment vibration, reduce the possibility of problems such as loosening and wear at the connection part, extend the service life of the equipment, and ensure the stable operation of the ship's power system.

[0029] Please refer to the above working process Figures 1 to 5 .

[0030] The following is the working process of the anti-loosening fastening mechanism 3 used to assist the connection between the first flange 11 and the second flange 13 to be stable during use and prevent them from loosening due to external factors: During use, after centering the axes of the first flange 11, the gasket 12 and the second flange 13, insert the bolt 31 into the first flange 11, the gasket 12 and the second flange 13. Then, socket two nuts 32 at both ends of the bolt 31, gently tighten the nuts 32, and then gradually tighten them in a diagonal order to ensure that the connection surface between the first flange 11 and the second flange 13 is evenly stressed. During the tightening process, with the assistance of the auxiliary disassembly and leveling mechanism 2, the leveling of the installation surface is assisted. During the tightening process, the strain gauges 33 arranged on the symmetry plane of the nut 32 gradually approach the first flange 11 and the second flange 13 synchronously. Then, after tightening, when the nut 32 is tightly connected to the surfaces of the first flange 11 and the second flange 13, the bolt 31 is in a state of a certain tensile stress, and the nut 32 also bears the corresponding pressure. The strain gauges 33 adhered to the side of the nut 32 close to the first flange 11 and the second flange 13 will generate an initial strain due to the pressure received by the nut 32, and their internal resistance values will change correspondingly, forming a stable initial electrical signal input value. This initial value is recorded by the monitoring system of the external controller as a reference for judging the state of the nut 32. If the nut 32 becomes loose during continuous use, the tensile force received by the bolt 31 decreases, and the pressure borne by the nut 32 also decreases accordingly. The strain degree of the strain gauge 33 changes due to the pressure change, resulting in a change in its resistance value. This change in the resistance value will cause a change in the current or voltage passing through the strain gauge 33, thereby causing a significant change in the output electrical signal. The monitoring system of the controller real-time collects the electrical signal of the strain gauge 33 and compares and analyzes it with the initial reference signal to feedback whether the nut 32 becomes loose during use and deal with it in a timely manner; Furthermore, when the monitoring system of the controller feeds back that the nut 32 is loose, the controller sends a signal to control the driving screw 37 to be energized and rotate in the reverse direction. When the driving screw 37 rotates in the reverse direction, the expansion disk 38 threaded thereon synchronously moves toward the driving end of the driving screw 37. During the movement of the expansion disk 38, since the expansion disk 38 is composed of three disks with different diameters, the largest disk of the expansion disk 38 gradually fits against the inner surface of the expansion body 36 when moving toward the driving end of the driving screw 37, and squeezes the four expansion bodies 36 to make them gradually move toward the outer ring of the bolt 31, and fit more closely with the inner threaded surfaces of the first flange 11 and the second flange 13. By enlarging the partial diameter of the bolt 31, the tightness of the connection between the bolt 31 and the first flange 11 and the second flange 13 is improved to avoid more effects caused by loosening.

[0031] By setting the strain gauge 33, the state change of the nut 32 can be sensed in real time. When the nut 32 becomes loose, the strain gauge 33 converts the mechanical strain into an electrical signal and feeds it back to the monitoring system, so that the loosening of the nut 32 can be discovered at the first time, and timely measures can be taken to avoid more serious problems caused by the supported fixture. Moreover, it is installed on the nut 32 without direct contact with other components. The non-contact measurement method will not cause additional interference or impact on the connection structure of the nut 32 and the first flange 11 and the second flange 13, thereby ensuring the integrity and stability of the connection structure under normal working conditions, and it is easier to integrate with the detection system, so that multiple strain gauges 33 can be formed into a sensor network to conduct comprehensive detection of the entire connection, realize automatic fault diagnosis and feedback, and thus control the stable progress of the next operation.

[0032] By setting the anti-loosening fastening mechanism 3, when the nut 32 is loosened and with the feedback of the strain gauge 33, the driving screw 37 is controlled to rotate forward, so that the expansion disk 38 contacts the expansion body 36 surface, so that it moves toward the outer ring of the bolt 31 to expand the diameter of the bolt 31, and the tightness of the connection between the first flange 11 and the second flange 13 is effectively prevented. Relative displacement or looseness between the first flange 11 and the second flange 13 is prevented, and the connection between the shaft belt generator body 1 and related components is firm, the stability of the equipment during operation is guaranteed, the safety hazards caused by loose connection are reduced, the power supply and overall operation safety of the ship are guaranteed, and the risk of equipment failure or accident caused by loose bolts 31 and nuts 32 is reduced. In addition, it is started and adjusted in real time according to the loosening situation without frequent manual inspection and tightening. This automatic compensation function can respond to emergencies in a timely manner and ensure the reliability of the connection.
