Description

Technical Field

[0001] This application relates to the field of ancient ship archaeological excavation and relates to a mast support device. Background Technology

[0002] During the archaeological excavation of ancient ships, once the ships are salvaged from the water, their wooden components, no longer supported by the buoyancy of the seawater, experience significant changes in internal pressure distribution, making them susceptible to structural instability or even damage. Providing safe and effective reinforcement without compromising the original fragile structure of the ancient ship to restore its mechanical balance and ensure the smooth progress of subsequent archaeological research has become a key challenge in this field.

[0003] Currently, the reinforcement of masts and hulls of ancient ships mainly relies on two common methods: welded steel pipe frames and manual scaffolding. However, both techniques have significant shortcomings. While welded steel pipe supports provide rigid fixation, their structure is simple and lacks flexibility. If the shape of the ancient ship changes slightly or an angle needs to be adjusted, the entire frame cannot adapt. More seriously, the vibrations generated during dismantling can easily cause secondary damage to the ancient ship. On the other hand, manual scaffolding is not only inefficient, consuming a lot of manpower, and slow to erect, but also lacks the precision to meet the strict requirements for support stability and accurate positioning in archaeological conservation. Overall, it cannot simultaneously meet the needs of safety, efficiency, and the preservation of the integrity of cultural relics. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0021] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, this embodiment provides a mast support device, which has a support assembly, a track 23 on the support assembly, a moving part 30 and a first drive mechanism 40 on the support assembly, the moving part 30 being slidably connected to the track 23; the first drive mechanism 40 being connected to the moving part 30 and used to drive the moving part 30 to slide along the track 23.

[0023] The device also has a rotating component 50 and a second driving mechanism 60. The rotating component 50 is rotatably connected to the moving component 30 via a first rotating shaft 71. The second driving mechanism 60 is mounted on the moving component 30 and connected to the rotating component 50, and is used to drive the rotating component 50 to rotate around the first rotating shaft 71.

[0024] Furthermore, the device has a clamping component 80, which is connected to the rotating component 50. The inner surface of the clamping component 80 has a fitting portion 801 that is adapted to the surface shape of the mast 90. The fitting portion 801 is used to contact and wrap the mast 90 to support the mast 90.

[0025] Thus, driven by the first drive mechanism 40, the moving component 30 achieves directional translation, driving the rotating component 50 to move. Driven by the second drive mechanism 60, the rotating component 50 rotates, causing the clamp component 80 to rotate to a suitable tilt angle to cooperate with the mast 90. This device achieves bidirectional adjustment of the mast 90 support in both horizontal and rotational directions, corrects the attitude of the clamp component 80, and ensures precise contact between the clamp component 80 and the surface of the mast 90.

[0026] The mast support device provided in this embodiment achieves flexible adjustment of the position and angle of the ancient ship's mast through the sliding connection between the track 23 on the support component and the moving component 30, in conjunction with the first drive mechanism 40 driving the moving component 30 to slide precisely along the track 23, and the rotating component 50 rotating through the first rotating shaft 71 and linked with the second drive mechanism 60. The fitting part 801 on the clamp component 80, which is adapted to the surface shape of the mast 90, can closely contact and evenly support the mast 90, avoiding the risk of secondary damage caused by rigid structural fixation, and eliminating the risk of vibration without cutting and dismantling. This design not only significantly improves the construction efficiency and saves labor costs, but also ensures the stability and precise positioning of the support, effectively restoring the mechanical balance of the ancient ship after it is brought to the surface, and providing a safe and reliable protective foundation for archaeological research.

[0027] In this embodiment, the first drive mechanism 40 and the second drive mechanism 60 are respectively adopted as cylinder telescopic mechanisms. The first drive mechanism 40 drives the moving part 30 to slide by cylinder telescopic movement, and the second drive mechanism 60 drives the rotating part 50 to rotate by cylinder telescopic movement.

[0028] Specifically, such as Figure 3 As shown, in this embodiment, one end of the second drive mechanism 60 is rotatably connected to the moving component 30 via the second rotating shaft 72, and the other end is rotatably connected to the rotating component 50 via the third rotating shaft 73. The positions of the first rotating shaft 71, the second rotating shaft 72, and the third rotating shaft 73 are arranged in a triangle. The second drive mechanism 60 drives the rotating component 50 to rotate around the first rotating shaft 71 through its own telescopic movement, thereby realizing the adjustment of the tilt angle of the clamp component 80.

[0029] In this embodiment, the first drive mechanism 40 drives the moving component 30 to make precise horizontal displacement along the track 23; the rotating component 50 is rotatably connected to the moving component 30 through the first rotating shaft 71; the second drive mechanism 60 forms a triangular connection with the moving component 30 and the rotating component 50 through the second rotating shaft 72 and the third rotating shaft 73, driving the rotating component 50 to rotate and fine-tune around the first rotating shaft 71. Specifically, the first drive mechanism 40 adopts a servo electric cylinder, such as an electric actuator of model EAM-40S or an SCL-50 series linear motor; the second drive mechanism 60 adopts a rotary servo electric cylinder, such as a model of REXROTH-EMG22 or FESTO-DSME22 series, whose three rotating shafts are arranged in an equilateral triangle or a right triangle to ensure the stability and accuracy of the rotational motion.

[0030] In one embodiment, the rotating component 50 adopts an obtuse triangular structure, such as a 120-degree obtuse-angled aluminum triangular bracket or a 110-degree obtuse-angled stainless steel bracket, with the first rotating shaft 71 located at the vertex of the obtuse angle. The clamp component 80 is detachably connected to the side of the rotating component 50 corresponding to the obtuse angle. The obtuse triangular structure of the rotating component 50 facilitates the balance of forces, ensuring precise and stable rotation. The triangular shaft arrangement of the second drive mechanism 60 ensures smooth and unhindered rotation, solving the problem of poor fit caused by the varying tilt angle of the mast 90 and avoiding local high-pressure points generated by rigid support. The structural design of the obtuse triangular rotating component 50 makes the torque distribution more reasonable, and the first rotating shaft 71 at the obtuse angle becomes a natural channel for stress concentration points.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the support assembly is divided into a two-section adjustable structure. The support assembly includes a first support portion 10 and a second support portion 20. One end of the first support portion 10 has a first connecting seat 11, which is used to fix the first support portion 10 on an existing equipment base; the other end of the first support portion 10 has a second connecting seat 12, and the second support portion 20 is detachably connected to the second connecting seat 12; preferably, the first connecting seat 11 and the second connecting seat 12 can be connected by bolts respectively.

[0032] Optionally, the width of the first support portion 10 gradually decreases from the end where the first connecting seat 11 is located to the end where the second connecting seat 12 is located, so as to improve the support stability of the first support portion 10.

[0033] In this embodiment, the second support portion 20 is set at an angle to the first support portion 10. The first support portion 10 is connected to the existing base and extends upward, thereby raising the support height of the device. The second support portion 20 extends obliquely relative to the first support portion 10 to move closer to the mast 90. Preferably, the second support portion 20 is set horizontally, the track 23 is set on the second support portion 20, and the moving part 30 slides relative to the second support portion 20 to achieve horizontal support adjustment.

[0034] In one embodiment, such as Figure 2 As shown, the second support 20 consists of two parallel support arms 21. One end of each support arm 21 is connected to the second connecting seat 12, and the other end is a free end. A gap 22 is formed between the two support arms 21 to provide a receiving space. The first drive mechanism 40 is disposed within the gap 22 and is detachably connected to the two support arms 21. Tracks 23 are respectively disposed on the two support arms 21, and the moving part 30 is disposed within the gap 22 and slides in cooperation with the tracks 23 on both sides. The two support arms 21 are arranged on both sides of the first drive mechanism 40 and the moving part 30 to ensure that the moving part 30 is subjected to balanced forces, thereby providing stable support for the first drive mechanism 40 and the moving part 30 and contributing to the structural stability of the device.

[0035] Furthermore, such as Figure 2 As shown, each support arm 21 adopts a double-layer plate structure, that is, the support arm 21 includes an inner plate 211 and an outer plate 212. The inner plate 211 and the outer plate 212 are arranged in parallel and welded to form a closed sliding cavity. The track 23 is embedded in the sliding cavity. The cross-sectional shape of the sliding cavity is a rectangular cavity or a U-shaped cavity to accommodate the track 23.

[0036] A limiting hole 2111 is provided on the inner side plate 211, and the extending direction of the limiting hole 2111 is consistent with the extending direction of the track 23. The moving part 30 passes through the limiting hole 2111 and connects to the track 23. The double-layer plate structure design allows at least a portion of the moving part 30 to be located between the inner side plate 211 and the outer side plate 212, so that the inner side plate 211 and the outer side plate 212 respectively play a role in holding the position of the moving part 30. Preferably, the limiting hole 2111 adopts an elongated oval hole or a waist-shaped groove design, such as an elliptical hole of 2mm × 30mm or a straight groove of 5mm width.

[0037] In this embodiment, please refer to Figure 2Each inner side plate 211 is provided with two limiting holes 2111. The first rotating shaft 71 is inserted into the limiting hole 2111 near the free end of the inner side plate 211, and the second rotating shaft 72 is inserted into the limiting hole 2111 near the second connecting seat 12. Under the push of the first driving mechanism 40, the moving part 30 moves, and the first rotating shaft 71 and the second rotating shaft 72 move along their respective limiting holes 2111. The limiting holes 2111 respectively play a limiting role for the first rotating shaft 71 and the second rotating shaft 72.

[0038] like Figure 3 As shown, in one embodiment, a plurality of sliders 31 are respectively provided on both sides of the moving part 30. The sliders 31 are disposed in the sliding cavity formed by the inner side plate 211 and the outer side plate 212 and connected to the track 23. While the sliders 31 are slidably connected to the track 23, they can also cooperate with the inner walls of the inner side plate 211 and the outer side plate 212 to achieve the function of maintaining position.

[0039] In one embodiment, the width of the support arm 21 gradually narrows along the free end direction, that is, the width of the support arm 21 gradually decreases from the end near the second connecting seat 12 towards the free end. In this way, the thickening of one end of the support arm 21 can increase the support strength of the support arm 21, increase the upper limit of the force and the stability; the other end of the support arm 21 is relatively thin to reduce the volume and its own weight, reserve space for the area of ​​the rotating component 50, and also add to the visual aesthetics of the device to a certain extent.

[0040] Preferably, in some embodiments, reinforcing ribs or triangular brackets may be provided on both sides of the support arm 21 to increase the support strength of the support arm 21 and prevent the support arm 21 from swinging to both sides.

[0041] Specifically, the first support part 10 adopts a double-sided stainless steel welded frame structure, such as a triangular support frame made of 304 stainless steel or a Q235 carbon steel coated triangular frame; the support arm 21 of the second support part 20 adopts a trapezoidal narrowing design, such as a linear narrowing structure that narrows from 150mm at the connecting end to 80mm at the free end or a segmented stepped narrowing structure; the limiting hole 2111 provided on the inner side plate 211 adopts an oblong hole or waist-shaped groove design, such as an elliptical hole of 2mm×30mm or a straight groove of 5mm width.

[0042] In this embodiment, the clamp component 80 adopts a detachable structure, and its fitting part 801 is customized to fit the actual contour of the mast 90. The clamp component 80 adopts a multi-lobed splicable structure, such as a three-lobed clamp system or a four-lobed clamp system. The fitting part 801 of each lobe is precisely shaped according to the local curved surface of the mast 90 using laser cutting technology.

[0043] Specifically, such as Figure 4As shown, the clamp component 80 includes a first clamp part 81, a second clamp part 82, and a third clamp part 83. The first clamp part 81, the second clamp part 82, and the third clamp part 83 can be three independent structures, or they can be connected as one piece and can be relatively movable to achieve opening or closing. The first clamp part 81, the second clamp part 82, and the third clamp part 83 can be spliced ​​to surround the mast 90, and the fitting part 801 of each of the first clamp part 81, the second clamp part 82, and the third clamp part 83 is in contact with the surface of the mast 90.

[0044] The clamp component 80 utilizes laser cutting technology to refine the complex shape of the mast 90, which has irregular curved surfaces, and precisely simulates a fit. This achieves the fine support effect of 3D printing at low cost, ensuring the stability of the mast 90 under load during the load-bearing process.

[0045] In this embodiment, one of the first clamping part 81, the second clamping part 82, and the third clamping part 83 is connected to the rotating component 50. For example... Figure 4 As shown, a mounting groove 811 is provided on the outer side wall of the first clamping part 81. The mounting groove 811 is used to cooperate with the side of the rotating part 50 and is detachably connected and fixed. Preferably, the first clamping part 81 can slide and adjust on the rotating part 50 to realize the position adjustment of the first clamping part 81.

[0046] This embodiment achieves precise support for the irregularly deformed mast 90 without damaging its original structure, avoiding the risk of localized stress concentration and secondary damage caused by rigid fixing of the support device. It also overcomes the technical shortcomings of existing steel pipe welded frames, such as poor flexibility and susceptibility to vibration during disassembly. This embodiment solves the problem of fitting the irregular curved surface of the mast 90 through a bidirectional adjustment mechanism and a segmented clamp component 80.

[0047] In this embodiment, the clamp component 80 has a certain length along the extension direction of the mast 90 to increase the contact area with the mast 90 and to support the mast 90 more stably.

[0048] To avoid the risk of structural aging, instability, or even damage to the mast 90 during the support process, it is necessary to monitor the mast 90 in real time during the support process.

[0049] In one embodiment, pressure sensors are respectively provided at both ends of the clamp component 80 along the extension direction of the mast 90. The two pressure sensors are used to monitor the pressure borne at both ends of the clamp component 80 in real time. Under stable support, the contact surface of the clamp component 80 is smoothly attached to the mast 90. At this time, the pressure values ​​detected by the two pressure sensors should be equal. However, when the mast 90 becomes unstable due to structural aging during the support process, the pressure values ​​detected by the two pressure sensors will differ. Therefore, the difference in pressure values ​​detected by the two pressure sensors can be used to determine whether the mast 90 has become unstable during the support process and whether further adjustment is needed.

[0050] Specifically, a first pressure sensor can be installed at one end of the first clamp part 81, and a second pressure sensor can be installed at the other end of the first clamp part 81. The mast support device also has a control system. The first and second pressure sensors are electrically connected to the control system, which is also electrically connected to the second drive mechanism 60. The control system is used to collect pressure data from the first and second pressure sensors and monitor them in real time. When the pressure data from the first and second pressure sensors are the same, the mast 90 is in a stable support state with a relatively balanced support force. When the pressure data from the first and second pressure sensors are different, the mast 90 is in an unstable support state or the support is unbalanced. In this case, the mast 90 is easily damaged. In this state, the control system will respond by controlling the second drive mechanism 60 to operate, causing the rotating part 50 and the clamp part 80 to deflect slightly toward the side of the pressure sensor with the smaller pressure value until the pressure data from the first and second pressure sensors are the same, so that the mast 90 is stably supported.

[0051] Furthermore, an angle sensor can be installed between the first rotating shaft 71 and the rotating component 50 to detect the rotation angle of the rotating component 50. The angle sensor is electrically connected to the control system. The control system monitors the pressure in real time when the device is supported, and controls the rotation of the rotating component 50 and the clamp component 80 to achieve automatic adjustment when the mast 90 is detected to be unbalanced. During the rotation, the angle sensor records the rotation angle information and sends the data to the control system. By analyzing the rotation angle information, the control system can obtain the corresponding data on the degree of structural aging of the mast 90, which facilitates more intelligent maintenance of the mast 90.

[0052] The specific usage of this embodiment is as follows: At the archaeological excavation site of the ancient shipwreck, support was provided for the 9-meter-high main mast 90. First, the first support section 10 was installed, constructed using a double-sided welded frame of 304 stainless steel. Its first connecting seat 11 was fixed to a pre-installed base on the shipwreck deck using 12 M24 high-strength bolts. The second connecting seat 12 extended upwards at a 35-degree angle. Next, the second support section 20 was installed, constructed using Q235 carbon steel coated arms. Each support arm 21 consists of an inner plate 211 and an outer plate 212 welded together to form a U-shaped sliding cavity. The inner plate 211 is 8mm thick, the outer plate 212 is 6mm thick, and the distance between the two plates is 40mm. The width of the support arm 21 linearly narrows from 140mm at the second connecting seat 12 end to 70mm at the free end. The two support arms 21 are connected to the second connecting seat 12 via a hinge mechanism, forming a 45-degree angle. The first drive mechanism 40 is installed in the gap 22, and the slider 31 of the moving part 30 is embedded in the two side rails 23. The connecting shaft of the moving part 30 passes through the waist-shaped groove limiting hole 2111 (size 4mm×25mm) on the inner side plate 211 and is fastened to the rail 23.

[0053] The mast 90 has an irregular elliptical cross-section due to seawater erosion. First, the rotating component 50 is installed on the moving component 30, with the first rotating shaft 71 precisely positioned at the 115-degree vertex of the obtuse-angled triangular rotating component 50. When installing the clamp component 80, a three-part structure is used, with the first clamp part 81 fixedly connected to the obtuse-angled side of the rotating component 50 by bolts. The second drive mechanism 60 is activated, with its two ends connected to the moving component 30 and the rotating component 50 via the second rotating shaft 72 and the third rotating shaft 73, respectively, arranged in a right-angled triangle. By controlling the extension and retraction length of the rotary servo cylinder in the second drive mechanism 60, the rotating component 50 is rotated within a 0-35 degree range around the first rotating shaft 71, precisely matching the posture of the clamp component 80 with the tilt angle of the upper part of the mast 90. Simultaneously, the first drive mechanism 40 uses a servo cylinder to drive the moving component 30 to move horizontally along the track 23, adjusting the radial distance between the clamp component 80 and the mast 90. When the clamp component 80 approaches the surface of the mast 90 (approximately 50mm away), the operator installs the three clamp segments according to the actual deformation of the mast 90. The fitting portion 801 of each segment is customized based on local surface data obtained from laser scanning: the first clamp segment 81 fits the protruding area on the front side of the mast 90, the second clamp segment 82 fits the recessed area on the left side, and the third clamp segment 83 fits the deformed area on the right side. Fine-tuning with a rotary servo cylinder ensures that the three clamp segments fit perfectly and seamlessly connect, forming a complete support ring.

[0054] The mast support device provided in this embodiment constructs a lightweight, highly stable, and rapidly assembleable support frame to overcome the shortcomings of low efficiency of manual scaffolding and the inability of welded steel pipe frames to adapt to changes in mast shape. It also solves the problem of traditional support methods failing to evenly distribute loads during the mechanical balance restoration process after the ancient ship is salvaged. The segmented clamp component 80, through the splicing and combination of three or four segments, achieves full-coverage support for irregular curved surfaces. The pressure distribution on the mast 90 is significantly improved compared to traditional welded frames, effectively preventing the propagation of micro-cracks in the wooden structure of the mast 90, while also avoiding the risk of vibration during dismantling, thus solving the core problem of secondary damage mentioned in the background art.
