Description

Technical Field

[0001] This application belongs to the field of marine machinery and equipment technology, and more specifically, relates to a rotatable lifting fine adjustment code for installing the adjustment ring of a lifesaving communication buoy. Background Technology

[0002] Emergency rescue communication buoys are an important piece of equipment in disaster prevention and rescue systems, primarily used for rapid release in emergency situations to establish external communication. Currently, the installation of emergency rescue communication buoys only requires adjusting the height of the adjusting ring plate to ensure the buoy's flow guide is flush with the surface of the sound-absorbing tile.

[0003] Current technical requirements for the installation of emergency rescue communication buoys not only include adding rubber pads to the upper surface of the adjusting ring plate, but also require an indentation test to ensure that, with the bottom release mechanism of the buoy locked, the rubber pads on the upper surface of the buoy shell are subjected to uniform force and continuous indentation. Furthermore, the installation enclosure for the emergency rescue communication buoy is a closed cylindrical shell with a certain number of small-diameter water flow holes evenly distributed on the enclosure wall. The gap between the enclosure wall and the buoy is uniform, with only a small gap. Due to this space limitation, during the positioning, installation, and welding of the adjusting ring, it is difficult to first ensure that the buoy's flow guide is flush with the surface of the sound-absorbing tile by controlling the height of the adjusting ring; secondly, it is difficult to control the uniform force and continuous indentation of the rubber pads on the upper surface of the adjusting ring.

[0004] To address the above technical issues, specialized tooling needs to be designed to precisely adjust the positioning and installation of the adjustment ring of the emergency rescue communication buoy, ultimately ensuring that the installation of the emergency rescue communication buoy meets relevant technical requirements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a rotatable lifting fine adjustment code for installing the adjustment ring of a life-saving communication buoy. This aims to solve the problems of difficulty in ensuring that the buoy's flow guide is flush with the surface of the sound-absorbing tile by controlling the height of the adjustment ring during positioning, installation, and welding within a confined space, and the difficulty in controlling the uniform force and continuous indentation of the rubber pad on the upper surface of the adjustment ring.

[0006] To achieve the above objectives, this application provides a rotatable lifting precision adjustment code for installing the adjustment ring of a lifesaving communication buoy, including a top code seat, a thrust bearing, a telescopic bushing, and an adjusting screw. The top code seat includes a base and a locking screw, with the locking screw vertically fixed to one side of the base. An axial through hole is provided at the center of the base, and the adjusting screw passes through the through hole. The thrust bearing and the telescopic bushing are coaxially arranged and fitted onto the adjusting screw. The end of the telescopic bushing away from the thrust bearing abuts against the buoy adjustment ring. When the adjusting screw rotates, it can extend and retract axially, thereby driving the telescopic bushing to push the buoy adjustment ring up and down axially. A locking nut and a pressure plate are fitted onto the locking screw. The locking nut can drive the pressure plate to press against the base, thereby locking the buoy enclosure located between the two.

[0007] Furthermore, multiple rotation marks are provided on the periphery of the other end of the adjusting screw, and the rotation marks are evenly distributed in a radiating pattern around the center of the other end face of the adjusting screw.

[0008] Furthermore, the included angle between adjacent rotation marks is 36°, and the lifting height increases by 0.1mm for every 36° rotation of the adjusting screw.

[0009] Furthermore, a hexagonal screw is coaxially provided on the other end of the adjusting screw, which is used to cooperate with an external tool to make the adjusting screw rotate by force.

[0010] Furthermore, a spirit level is provided on the side wall of the locking nut to monitor the levelness of the top bracket installation.

[0011] Furthermore, the telescopic bushing is hollow inside and has internal threads on its inner wall, while the adjusting screw has external threads on its outer side, and the internal threads and external threads are connected in a mating manner.

[0012] Furthermore, a set screw is provided on one end of the telescopic bushing near the buoy adjustment ring. The set screw abuts against the buoy adjustment ring to prevent the telescopic bushing from rotating circumferentially relative to the adjustment screw.

[0013] Furthermore, an anti-rotation plate is also provided between the top screw and the buoy adjustment ring.

[0014] Furthermore, a rubber compression pad is provided between the clamping plate and the buoy fence.

[0015] Furthermore, the rubber compression pad is fixed to the pressure plate by countersunk screws, and the thickness of the rubber compression pad at the non-fixed connection position is greater than the thickness at its fixed connection position.

[0016] Overall, the technical solutions conceived in this application have the following beneficial effects compared with the prior art: (1) This application utilizes the coordinated transmission of the adjusting screw and the telescopic bushing. When the adjusting screw is rotated, the telescopic bushing, whose rotation is restricted by the set screw, converts the rotational motion into a pure linear motion, thereby achieving precise lifting or lowering of the adjusting ring. This completely avoids the impact and uncertainty that may exist in traditional methods, ensuring the flatness and installation position accuracy of the adjusting ring, thus guaranteeing the stability of the life-saving communication buoy's performance under complex sea conditions.

[0017] (2) This application integrates the lifting and locking functions into a compact base. During operation, only the standard tool is needed to rotate the adjusting screw to complete the fine adjustment, and then the locking nut is tightened to complete the fixation. This greatly simplifies the operation process and reduces the requirements for the number and skills of operators. Especially in complex environments such as offshore operations, it can significantly improve installation efficiency and safety.

[0018] (3) The thrust bearing in this application effectively eliminates the frictional torque when the adjusting screw rotates, making the lifting process extremely smooth and avoiding installation stress or thread damage caused by jamming. It has a strong locking force, and the unique locking mechanism (locking screw, nut and pressure plate) can generate a huge clamping force, like a "steel clamp" to firmly lock the buoy fence. This mechanical locking is more reliable than temporary welding and has no heat-affected zone, making it especially suitable for marine environments with high requirements for corrosion resistance.

[0026] The embodiments of this application are described below with reference to the accompanying drawings.

[0027] This embodiment provides a rotatable lifting fine adjustment code for installing the adjustment ring 9 of a life-saving communication buoy, such as... Figure 1As shown, the device includes a top bracket 1, a thrust bearing 2, a telescopic bushing 3, and an adjusting screw 7. The top bracket 1 includes a base 11 and a locking screw 12, which is vertically fixed to one side of the base 11. An axial through hole is provided in the center of the base 11, through which the adjusting screw 7 passes. The thrust bearing 2 and the telescopic bushing 3 are coaxially arranged and fitted onto the adjusting screw 7. The end of the telescopic bushing 3 away from the thrust bearing 2 abuts against the buoy adjustment ring 9. When the adjusting screw 7 rotates, it can extend and retract axially, thereby driving the telescopic bushing 3 to push the buoy adjustment ring 9 up and down axially. A locking nut 6 and a pressure plate 5 are fitted onto the locking screw 12. The locking nut 6 can drive the pressure plate 5 to press against the base 11, thereby locking the buoy enclosure 10 located between the two.

[0028] like Figure 2 As shown, the other end of the aforementioned adjusting screw 7 is provided with multiple rotation marks 71. The rotation marks 71 are multiple scale lines, which are arranged in a radiating pattern around the center of the other end face of the adjusting screw 7. The included angle between adjacent rotation marks 71 is 36°. When the adjusting screw 7 rotates 36°, the lifting height increases by 0.1mm. In other embodiments, the included angle between adjacent rotation marks 71 can also be other angles, and the lifting height corresponding to each scale rotation can also be different, and the corresponding lifting accuracy is also different.

[0029] The other end of the aforementioned adjusting screw 7 is also coaxially provided with a hexagonal screw (i.e., a hexagonal head), which is used to cooperate with external tools to make the adjusting screw 7 rotate by force.

[0030] Specifically, the main component of the rotatable lifting and fine-tuning code provided in this embodiment, the code holder 1, is a detachable code holder with a small diameter, thus allowing for... Figure 3 As shown, six sets of rotatable lifting and fine-adjustment codes are evenly arranged circumferentially between the confining wall of the cylindrical trap and the rescue communication buoy. These codes are then locked and fixed inside the confining wall via the code holder 1, the clamping plate 5, and the locking nut 6. A right-angle wrench is passed through the drainage hole in the confining wall and fitted onto the hexagonal head of the lifting and fine-adjustment code adjusting screw 7. This allows for operation of the adjusting screw 7 from outside the confining wall. Rotating the adjusting screw 7 forward and backward drives the telescopic bushing 3 to rotate synchronously in both directions. Simultaneously, the anti-rotation plate of the set screw 4 is pressed down by the gravity of the adjusting ring. When the telescopic bushing 3 rotates forward, the thread of the set screw 4 extends, pushing the adjusting ring upward; when it rotates backward, the thread of the set screw 4 retracts, and the adjusting ring descends accordingly. With precise adjustment through the 6 sets of circumferential adjustment rings and the top lifting fine adjustment code, the installation of the life-saving communication buoy adjustment ring 9 can be realized; the selection of the thrust bearing is mainly to reduce the friction between the detachable top code seat 1 and the telescopic bushing 3, and at the same time, the thrust bearing can smoothly transmit rotational force, making it easier to operate the lifting and lowering of the top code.

[0031] like Figure 4As shown, the upper figure is a front view of the top bracket 1, and the lower figure is its top view. A level 61 is provided on the side wall of the aforementioned locking nut 6 to monitor the levelness of the top bracket 1 during installation. More specifically, the level 61 can be magnetic and can be attached to any side of the locking nut 6, or it can be directly fixed to one side of the locking nut 6 by adhesive.

[0032] like Figure 5 As shown, the telescopic bushing 3 is hollow inside and has an internal thread on its inner wall. The adjusting screw 7 has an external thread on its outer side. The internal thread and the external thread are connected to fix the telescopic bushing 3 and the adjusting screw 7, and the telescopic bushing 3 can rotate synchronously with the adjusting screw 7. Both the telescopic bushing 3 and the adjusting screw 7 are made of brass.

[0033] The aforementioned telescopic bushing 3 is also provided with a type of... Figure 6 The set screw 4 shown abuts against the float adjustment ring 9 to prevent the telescopic bushing 3 from rotating circumferentially relative to the adjusting screw 7.

[0034] Specifically, the set screw 4 has an external thread on its outer side. The set screw 4 passes through the telescopic bushing 3, and its external thread engages with the internal thread of the telescopic bushing 3. The set screw 4 mainly serves a circumferential positioning function here, rather than bearing large axial forces or realizing transmission. The set screw 4 allows the telescopic bushing 3 to move axially along the adjusting screw, but locks it from unnecessary circumferential rotation. Without the constraint of the set screw 4, the telescopic bushing 3 may rotate freely along with the adjusting screw 7, and the required lifting and lowering action cannot be achieved. By limiting the rotation, the set screw 4 ensures that the rotation of the adjusting screw 7 can be effectively converted into the linear motion of the telescopic bushing 3.

[0035] An anti-rotation plate 41 is also provided between the aforementioned set screw 4 and the float adjustment ring 9, which increases the contact area between the set screw 4 and the adjusted part, making the fine adjustment process more stable.

[0036] like Figure 7 As shown, a rubber compression pad 51 can also be provided between the pressure plate 5 and the buoy fence 10, and the rubber compression pad 51 is fixed to the pressure plate 5 by countersunk screws. The thickness of the non-fixed connection position of the rubber compression pad 51 is greater than the thickness at its fixed connection position. The pressure plate 5 can be locked to the buoy fence 10 by measuring the compression amount of the rubber compression pad 51.

[0037] In this embodiment, when the detachable top code seat 1 is welded to the transverse stud, the height of the weld leg must be lower than the thread height so that the buoy trap wall and the top code seat 1 are completely fitted when the nut is tightened.

[0038] When the aforementioned clamping plate 5 is prepared, it is bent in combination with the curvature of the buoy enclosure wall so that the clamping plate 5 is completely fitted with the buoy enclosure wall when the nut is tightened.

[0039] The internal thread of the aforementioned telescopic bushing 3, the external thread of the set screw 4, and the external thread of the adjusting screw 7 are all selected as fine threads.

[0040] The aforementioned thrust bearing is selected as a small-sized model with high pressure resistance. It must match the size of the rotatable lifting fine adjustment code and be installed on the adjusting screw 7. It can support the adjusting screw 7 and determine its axial position, ensuring that the correct axial clearance is maintained between the rotating parts and the stationary parts, and preventing axial friction and collision.

[0042] Furthermore, in this application, the expression "and / or" includes any and all combinations of the associated listed words. For example, the expression "A and / or B" may include A, may include B, or may include both A and B.

[0043] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0044] Furthermore, the mathematical concepts mentioned in the embodiments of this application, such as symmetry, equality, parallelism, and perpendicularity, are limitations specific to the current technological level, rather than absolute and strict mathematical definitions. Slight deviations are permissible; approximations of symmetry, equality, parallelism, and perpendicularity are all acceptable.
