Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a floating bridge belt conveyor. Background Technology

[0002] In fields such as water conservancy projects, port logistics, waterborne construction, and land reclamation, it is often necessary to transport bulk materials (such as sand, gravel, coal, and construction waste) over long distances across waterways. Floating bridge conveyor belts, as a type of conveying equipment that relies on floating supports and can operate on water, have advantages such as short construction cycles, low costs, and strong adaptability, as they do not require the construction of fixed bridges or tunnels. Therefore, they have become one of the core pieces of equipment for waterborne material transport.

[0003] Floating bridge belt conveyors typically consist of a conveyor belt, a floating support structure, a head drive unit, and a tail tensioning device. Their core design concept is to achieve cross-area transportation on water by using the floating structure to support the conveying mechanism. However, in practical applications, existing floating bridge belt conveyors still have the following significant drawbacks: 1. The movement and steering functions are weak, making it difficult to quickly adjust the unloading position and limiting the operating range. More importantly, these devices generally do not have adaptive protection structures for wind and wave conditions. Under the impact of sea wind or waves, they are prone to overall shaking, rotation or lifting displacement, causing materials on the belt to fall off, or even causing equipment overturning accidents, which seriously affect the safety and reliability of operations.

[0004] 2. No special protective structure was designed for the impact of wind and waves. When wind and waves directly act on the floating body and the head support mechanism, it will not only aggravate the shaking of the equipment, but may also cause the floating body to capsize. In addition, there is no adaptive locking trigger mechanism based on the intensity of wind and waves. It cannot automatically adjust the locking state according to the actual working conditions, and manual real-time monitoring and operation are required, which increases labor costs and operational difficulty.

[0005] 3. Most simple floating devices lack an effective lifting and adjustment mechanism, and cannot adjust the height of the head or tail of the conveyor belt in real time according to changes in water level. When operating in sea areas with large tidal ranges, problems such as poor material conveying or equipment soaking are likely to occur.

[0006] Therefore, it is necessary to invent a floating bridge belt conveyor to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a floating bridge belt conveyor to solve the problems mentioned in the background art, such as the difficulty in quickly adjusting the unloading position and the limited operating range.

[0013] Optionally, the head support mechanism also includes locking structure one and locking structure two, and a drive structure for driving locking structure one and locking structure two. Locking structure one and locking structure two are respectively installed on the directional plate and the top plate, and the drive structure is located below the bottom plate and connected to locking structure one.

[0014] Optionally, the drive structure includes two sets of wave-damping plates, two sets of trapezoidal blocks, two sets of support rods, two sets of gear plates, two reset devices, and gears; The two ends of the receiving rod are fixedly connected to the trapezoidal block and the wave-damping plate, respectively. The trapezoidal block is located between the locking structure and the base plate. The gear plate is fixedly installed on the outside of the receiving rod and meshes with the gear. The gear is rotatably installed on the bottom of the base plate and drives the other gear to slide synchronously when one of the gear plates slides. The reset device is installed on the bottom of the base plate and fixedly connected to the receiving rod.

[0015] Optionally, the locking structure includes a float plate, an airbag, a lifting column, a collar, a swing arm, and a compression plate; The floating plate is located below and in contact with the trapezoidal block. The airbag is bonded to the bottom of the floating plate. Multiple lifting columns are provided and fixedly installed on the top of the floating plate, extending upward into the interior of the directional plate. Multiple collars are provided and fixedly installed on the outside of the lifting columns. The extrusion plate is slidably installed inside the directional plate and abuts against the inner wall of the directional plate. Multiple swing arms are provided and hinged between the extrusion plate and the collars, pushing the extrusion plate to slide when the collars are raised and lowered.

[0016] Optionally, multiple limiting teeth are provided on the side of the extrusion plate that is close to the slider, so that when the extrusion plate slides toward the slider, the two sets of limiting teeth interlock and mesh with each other.

[0017] Optionally, the second locking structure includes a limiting block, a second spring, an inner ring, an inner ring limiting protrusion, an outer ring, a limiting slider, a load-bearing plate, and a third spring.

The two ends of spring 3 are connected to the outer ring and the load-bearing plate respectively.

[0018] The technical effects and advantages of this invention are as follows: 1. The floating bridge head support mechanism of the present invention can support the tail of the conveyor to float on the water surface, and transport materials to the tail of the conveyor through the intermediate conveying part. The materials are unloaded from the tail of the conveyor to complete the transportation of materials or the transportation of land reclamation materials between different positions on the water surface.

[0019] 2. The present invention enables the conveyor belt to move on the sea surface through the setting of the walking mechanism, and adjusts the unloading position of the conveyor belt or the position of the land reclamation material. With the cooperation of the winch and the slewing mechanism, the conveyor belt can be rotated relative to the walking mechanism, so as to realize the flexible adjustment of the equipment in the working area.

[0020] 3. The slider of the head support mechanism of the present invention slides up and down along the slide rail, which can flexibly adjust the height of the conveyor head to adapt to changes in water level. Locking structure one and locking structure two lock the lifting and rotating directions of the belt conveyor, ensuring the structural stability of the belt conveyor after adjustment or under wind and waves, preventing the belt conveyor from rotating and lifting under the impact or push of wind and waves, which would cause the goods or soil on the belt conveyor to fall or come into direct contact with seawater. At the same time, it can also greatly improve the stability of construction personnel when walking on the belt conveyor.

[0021] 4. The drive structure of this invention senses the intensity of wind and waves through a wave-damping plate. When the wind and waves are large, the wave-damping plate drives the support rod to slide. Through the meshing transmission of the gear plate and gears, the locking structure one and the locking structure two are driven to lock simultaneously, realizing adaptive protection based on wind and wave conditions. No real-time manual monitoring is required, reducing labor costs and improving the safety of equipment operation. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides, for example Figure 1-13The floating bridge conveyor shown includes a conveyor 100 consisting of a conveyor tail section 110, an intermediate conveyor section 120, and a conveyor head section 130. The two ends of the intermediate conveyor section 120 are fixedly connected to the conveyor tail section 110 and the conveyor head section 130, respectively. The intermediate conveyor section 120 is the main load-bearing part of the conveyor 100 and consists of multiple conveyor rollers and a conveyor belt. The conveyor belt conveys materials by driving the rotation of the rollers. Its length can be adjusted according to the actual conveying distance. The bottom of the intermediate conveyor section 120 is provided with a pontoon for supporting the floating of the intermediate conveyor section 120. The bottom of the conveyor tail section 110 is equipped with a floating bridge head support mechanism 140. The conveyor tail section 110 serves as the output end of the material, while the floating bridge head support mechanism 140 supports the conveyor tail section 110 through the principle of buoyancy, enabling it to operate stably on the water surface. It is suitable for conveying scenarios that cross water areas or have large water level changes. A head support mechanism 200 is provided on the outer side of the conveyor head 130. The head support mechanism 200 primarily provides a stable installation foundation for the belt conveyor 100 and, under external force, moves and adjusts the position of the belt conveyor 100. Simultaneously, it restricts the circumferential sway of the belt conveyor 100, ensuring that the belt conveyor 100 can only move up and down under the influence of buoyancy. A traveling mechanism 300 is provided on the top of the head support mechanism 200 to move the belt conveyor 100. The discharge port of the traveling mechanism 300 is connected to the inlet of the conveyor head 130 via an elastic folded hose. After goods or soil are conveyed to the discharge port of the traveling mechanism 300, they fall into the interior of the elastic folded hose and are guided from the hose to the conveyor head 130. The material falls onto the intermediate conveyor section 120 for transport. The traveling mechanism 300 typically includes components such as a drive wheel, a driven wheel, a guide wheel, and a drive motor, enabling the entire belt conveyor 100 to move horizontally or inclined on a predetermined track or ground to adapt to the conveying needs of different working areas. A slewing mechanism 400 is installed between the head support mechanism 200 and the traveling mechanism 300 to enable the traveling mechanism 300 to rotate relative to the head support mechanism 200. This allows the conveying direction of the belt conveyor 100 to be adjusted so that it can turn flexibly to meet the material conveying path requirements under complex working conditions. At the same time, the slewing mechanism 400 is used to connect the traveling mechanism 300 and the head support mechanism 200 to ensure the stability of the head support mechanism 200 during use. A winch 500 is installed on the intermediate conveyor section 120 to traction the belt conveyor 100. The winch 500 provides continuous and controllable traction force to the belt conveyor 100, ensuring that the conveyor belt can run smoothly in a predetermined direction and speed. The winch 500 consists of a motor, reducer, drum, wire rope, braking device and control system. The drum is used to wind the traction wire rope. The rotation of the drum drives the wire rope to be wound and unwound, thereby pulling the belt conveyor 100 to move. By installing the winch 500 in the intermediate conveyor section 120, the problem of traction force requirements in long-distance, high-capacity belt conveying can be effectively solved.

[0026] The floating bridge head support mechanism 140 can support the tail section 110 of the conveyor to float on the water surface, and transport materials to the tail section 110 of the conveyor through the intermediate conveying section 120. The materials are unloaded from the tail section 110 of the conveyor to complete the transportation of materials or the transportation of land reclamation materials between different positions on the water surface.

[0027] The walking mechanism 300 can drive the belt conveyor 100 to move on the sea surface, adjust the unloading position of the belt conveyor 100 or the position of the land reclamation material, and, in conjunction with the winch 500 and the slewing mechanism 400, drive the belt conveyor 100 to rotate relative to the walking mechanism 300, so as to realize the flexible adjustment of the equipment in the working area.

[0028] The working principle of this embodiment is as follows: When adjusting the position of the belt conveyor 100, the driving mechanism 300 is moved, and the restriction on the wire rope on the winch 500 is released. The driving mechanism 300 drives the belt conveyor 100 to move on the sea surface through the head support mechanism 200. When the position of the belt conveyor 100 is adjusted, the winch 500 is started, so that the winch 500 drives the drum to wind the wire rope and cooperates with the restriction of the slewing mechanism 400. The traction caused by the shortening of the wire rope drives the belt conveyor 100 to rotate and adjust the direction of the belt conveyor 100.

[0029] Start the conveyor belt located on the intermediate conveyor section 120 so that the intermediate conveyor section 120 transports the soil or goods falling from the conveyor head 130 to the conveyor tail 110 and the designated position from the conveyor tail 110.

[0030] In order to achieve the normal transportation of soil or goods, in some embodiments of the present invention, reference is made to... Figures 2-5As shown, a first upper idler roller 121 is provided at the top of the intermediate conveyor section 120. The first upper idler roller 121 is a three-section trough type idler roller. The first upper idler roller 121 is used to support the upper surface of the conveyor belt, ensuring that the conveyor belt remains stable during operation and reducing deviation caused by gravity. A lower idler roller 122 is provided inside the intermediate conveyor section 120. The lower idler roller 122 is a flat idler roller. The lower idler roller 122 supports the lower surface of the conveyor belt, reducing the load of the conveyor belt's own weight on the conveyor frame, and works with the upper idler roller to maintain the normal operating trajectory of the conveyor belt. A second upper idler roller 123 is provided at the top of the intermediate conveyor section 120 near the conveyor head 130. The second upper idler roller 123 is a comb-type buffer idler roller. The second upper idler roller 123 is used to buffer material falling from a height onto the conveyor belt. When the conveyor belt is on the head section 130, the second upper idler roller 123 at its lower part provides stable support for the conveyor belt and buffers the impact to avoid belt damage. At the same time, it helps the conveyor belt to smoothly transition to the head area. The end of the intermediate conveyor section 120 is provided with a deflector roller 124. The function of the deflector roller 124 is to change the running direction of the conveyor belt, so that the conveyor belt can smoothly turn from the intermediate conveyor section to the tail section 110 or other connecting parts of the conveyor, ensuring the continuity of the conveying path. The tail section 110 of the conveyor is provided with a drive roller 125. The drive roller 125 is the core power transmission component of the conveyor. It is usually driven by a motor to rotate. When the conveyor belt passes around the drive roller, friction is generated between the drive roller and the conveyor belt, thereby driving the entire conveyor belt to circulate and realize the material conveying function.

[0031] To facilitate inspection work by operators, in some embodiments of the present invention, reference is made to... Figure 5 As shown, a working platform 111 is provided around the tail section 110 of the conveyor to ensure the safety and convenience of the operators during the operation. A working walkway 112 connected to the working platform 111 is provided on the outer side of the middle conveying section 120. At the same time, the position of the working walkway 112 should avoid interference with the moving parts of the conveyor, so as to ensure the normal operation of the conveyor and provide a convenient working path for the operators, so as to achieve effective maintenance and management of different areas of the conveyor.

[0032] In some embodiments of the present invention, reference is made to... Figure 5As shown, the floating bridge head support mechanism 140 includes two pontoons 141. The pontoons 141 support the conveyor tail 110 using the buoyancy of the water, ensuring that the conveyor tail 110 can float normally on the water surface. The two pontoons 141 are connected by a crossbeam 142 to enhance the structural stability between the two pontoons 141 and prevent relative displacement of the pontoons under water flow impact or load. A support column 143 is fixedly installed on the top of the pontoons 141 to support the conveyor tail 110, ensuring stable support of the weight of the conveyor tail 110. A connecting frame 144 is provided on the top of the support column 143 to form a reliable connection with the conveyor tail 110. The bottom of the conveyor tail 110 is provided with... A connecting support 145 is provided, which is a transition component between the tail end 110 of the conveyor and the head support mechanism 140 of the floating bridge. It is used to transfer the load of the tail end 110 of the conveyor to the connecting frame 144. A rotating joint 146 is installed between the connecting support 145 and the connecting frame 144. The rotating joint 146 allows a certain relative rotation between the connecting support 145 and the connecting frame 144, thereby adapting to the small angle changes or vibrations that may occur during the operation of the conveyor, reducing stress concentration caused by rigid connection, and improving the stability and service life of the entire support system. At the same time, a coil spring, torsion spring or increased friction can be set at the hinge of the rotating joint 146 to buffer and consume the rotational force received by the rotating joint 146.

[0033] In order to limit the slippage of the conveyor head 130, in some embodiments of the present invention, reference is made to... Figure 6 As shown, the head support mechanism 200 includes a base plate 210, two sets of directional plates 220, a slider 240, and a top plate 250; Each group of directional plates 220 has multiple plates, each fixedly connected to the bottom plate 210 and top plate 250 at both ends. The number of directional plates 220 in each group can be adjusted according to actual needs, generally 3-5, to ensure the smoothness and guiding accuracy of the slider 240's movement. A slide rail 230 is formed between each pair of adjacent directional plates 220. The slide rail 230 is the space between two adjacent directional plates 220, and its width and depth are designed according to the dimensions of the slider 240 to ensure that the slider can slide smoothly up and down within it, while preventing the slider from shifting or jamming during movement. The slider 240 is fixedly installed on the side of the conveyor head 130 by bolts or welding. When the conveyor head 130 needs to... When adjusting the height, the slider 240 will move vertically along the slide rail 230, thereby adjusting the height of the entire conveyor head. The top plate 250 is rotatably installed at the bottom of the traveling mechanism 300. As the basic component of the head support mechanism 200, the top plate 250 is used to support other components of the entire head support mechanism 200 and transmit loads to ensure the stability of the overall structure. The top plate 250 is connected to the bottom of the traveling mechanism 300 through rotating components such as a rotating shaft, so that the top plate 250 can rotate around the rotating component at a certain angle, thereby adapting to the installation requirements of different working environments or adjusting the posture of the conveyor head 130, while ensuring the stability and operability of the conveyor head.

[0034] In some embodiments of the present invention, reference is made to... Figure 6 As shown, the head support mechanism 200 also includes a locking structure 260 and a locking structure 270, and a drive structure 280 for driving the locking structures 260 and 270 to ensure its stability during operation. The locking structures 260 and 270 are respectively mounted on the directional plate 220 and the top plate 250. The drive structure 280 is located below the bottom plate 210 and connected to the locking structure 260. The drive structure 280 transmits power to the locking structure 260, thereby controlling the relative movement of the locking structures 260 and 270, realizing the locking or unlocking operation of the two, fixing the relative position between the directional plate 220 and the top plate 250, preventing displacement during use, and thus ensuring the overall stability and safety of the head support mechanism.

[0035] Among them, the slider 240 of the head support mechanism 200 slides up and down along the slide rail 230, which can flexibly adjust the height of the conveyor head 130 to adapt to changes in water level. The locking structure 1 260 and the locking structure 270 lock the lifting and rotating directions of the belt conveyor 100, ensuring the structural stability of the belt conveyor 100 after adjustment or under wind and waves, preventing the belt conveyor 100 from rotating and lifting under the impact or push of wind and waves, causing the goods or soil on the belt conveyor 100 to fall or come into direct contact with seawater. At the same time, it can also greatly improve the stability of construction personnel when walking on the belt conveyor 100.

[0036] In order to properly drive locking structure 260 and locking structure 270, in some embodiments of the present invention, reference is made to... Figure 6 , Figure 11 and Figure 12 As shown, the drive structure 280 includes two sets of wave-damping plates 281, two sets of trapezoidal blocks 282, two sets of supporting rods 283, two sets of gear plates 284, two reset devices 286, and gears 285. The two ends of the receiving rod 283 are fixedly connected to the trapezoidal block 282 and the wave-damping plate 281, respectively. The wave-damping plate 281 is an inclined plate-like structure used to block water flow or objects. Its main function is to maintain a stable force transmission path during equipment operation and reduce the impact of waves on the belt conveyor 100. The trapezoidal block 282 is located between the locking structure 260 and the base plate 210. The trapezoidal block 282 can effectively limit the displacement range of the locking structure 260. The gear plate 284 is fixedly installed on the outside of the receiving rod 283 and meshes with the gear 285. The gear 285 is rotatably installed on the bottom of the base plate 210. When one of the gear plates 284 slides, due to the gear plate 283... The meshing relationship between gear 4 and gear 285 will drive gear 285 to rotate synchronously, which in turn drives another gear plate 284 to slide synchronously, realizing coordinated control of the movement on both sides. The reset device 286 is installed at the bottom of the base plate 210 and fixedly connected to the receiving rod 283. The reset device 286 usually adopts the structure of spring, elastic rubber pneumatic device, etc. After the driving structure is subjected to external force, the reset device 286 can provide restoring force to return the receiving rod 283, trapezoidal block 282, wave baffle 281 and other components to their initial positions, ensuring the normal cycle operation of the equipment. Moreover, the reset device 286 is set so that it cannot push the wave baffle 281 to move when the waves are small.

[0037] Multiple wave-damping plates 281 are provided. Other wave-damping plates 281 correspond to the tail end 110 of the conveyor. The wave-damping plates 281 can be fixed together by connecting rods through movement and synchronous movement, and the sliding is restricted by slide rails to ensure smooth sliding. Alternatively, the gears 285 corresponding to the wave-damping plates 281 can be rotated synchronously by pulleys to achieve synchronous sliding of multiple wave-damping plates 281.

[0038] The drive structure 280 senses the intensity of wind and waves through the wave baffle 281. When the wind and waves are large, the wave baffle 281 drives the support rod 283 to slide. Through the meshing transmission of the gear plate 284 and the gear 285, the locking structure 1 260 and the locking structure 270 are driven to lock simultaneously, realizing adaptive protection based on wind and wave conditions. No real-time manual monitoring is required, reducing labor costs and improving the safety of equipment operation.

[0039] The working principle of this embodiment is as follows: When waves hit the belt conveyor 100, the wave-damping plates 281 are installed on both sides of the belt conveyor 100 and are inclined (the inclination angle of the wave-damping plates 281 is adjusted according to the transport direction of the belt conveyor 100). The waves will push the wave-damping plates 281 to move. When the wave-damping plates 281 move, they will drive the gear plate 284 and the trapezoidal block 282 to slide and drive the reset device 286 to store energy. The gear plate 284 will drive another set of trapezoidal blocks 282 and wave-damping plates 281 to slide synchronously through the gear 285. When the trapezoidal block 282 slides, it will be separated from the locking structure 260 and release the restriction on the locking structure 260. The locking structure 260 and the second locking structure 270 will be locked. After the waves pass, the reset device 286 will push the trapezoidal block 282 and the wave-damping plates 281 to reset. When the trapezoidal block 282 resets, it will push the locking structure 260 and the second locking structure 270 to release the locked state, preparing for the next wave.

[0040] In some embodiments of the present invention, the wave baffle 281 is composed of a damper, a flow guide pipe, a one-way valve, and a compression spring. The two ends of the flow guide pipe are respectively connected to the two ends of the damper, and the one-way valve is set on the flow guide pipe. The compression spring is set inside or outside the damper. The damper and the spring are normally compressed and stored when the wave baffle 281 moves. At the same time, during compression, part of the damping fluid flows to the other end through the flow guide pipe. After the wave passes, the stress of the damper and the compression spring is released, and the damping fluid cannot flow through the flow guide pipe, reducing the speed at which the damper and the compression spring push the wave baffle 281 to reset.

[0041] In order to lock the lifting and lowering of the belt conveyor 100, in some embodiments of the present invention, reference is made to... Figure 9 and Figure 13 As shown, the locking structure 260 includes a float plate 261, an airbag 262, a lifting column 263, a collar 264, a swing arm 265, and a compression plate 266. The floating plate 261 is located below and in contact with the trapezoidal block 282 to ensure that it can rise only when the trapezoidal block 282 shifts. The airbag 262 is bonded to the bottom of the floating plate 261 to provide sufficient buoyancy for its ascent. Multiple lifting columns 263 are provided and fixedly installed on the top of the floating plate 261, extending upward into the interior of the directional plate 220. The multiple lifting columns 263 ensure the stability of the floating plate 261 during the ascent and descent, preventing tilting or jamming caused by single-point force. Multiple collars 264 are provided and fixedly installed on the outside of the lifting columns 263. The compression plate 266 slides... The extrusion plate 266 is installed inside the directional plate 220 and abuts against the inner wall of the directional plate 220. When the extrusion plate 266 is subjected to external force, it moves towards or away from the slider 240, thereby realizing the locking or unlocking function of the special belt conveyor 100. Multiple swing arms 265 are provided and are hinged between the extrusion plate 266 and the collar 264. When the collar 264 is raised or lowered, it pushes the extrusion plate 266 to slide. As a transmission component, the swing arm 265 converts the linear motion of the collar 264 into the sliding motion of the extrusion plate 266 through the rotation of the hinge point when the collar 264 is raised or lowered, pushing the extrusion plate 266 to slide inside the directional plate 220, thereby completing the locking action. A spring can also be installed between the inner top wall of the directional plate 220 and the lifting column 263. The spring plays a role in resetting and buffering in the locking structure. When the external force disappears, the spring can push the lifting column 263 back to the initial position, so that the pressing plate 266 is released from the locked state, ensuring the normal operation and safety of the structure.

[0042] The working principle of this embodiment is as follows: When the floating plate 261 rises, it drives the lifting column 263 to rise synchronously. When the lifting column 263 rises, the compression spring 1 pushes the compression plate 266 towards the slider 240 through the swing arm 265, so that the compression plate 266 and the slider 240 are squeezed together. When the floating plate 261 falls under the push of the trapezoidal block 282, the elastic force of the spring 1 is released, causing the lifting column 263 to fall and releasing the compression plate 266 from the slider 240.

[0043] To enhance the locking effect of the locking structure 260, in some embodiments of the present invention, reference is made to... Figure 10As shown, multiple limiting teeth 268 are provided on the side of the extrusion plate 266 that is close to the slider 240. When the extrusion plate 266 slides towards the slider 240, the two sets of limiting teeth 268 interlock with each other. The limiting teeth 268 are arranged periodically along the relative sliding direction of the extrusion plate 266 and the slider 240. Each limiting tooth 268 has a certain height and width and its cross-sectional shape is trapezoidal. This ensures that during the process of the extrusion plate 266 sliding towards the slider 240, the two sets of limiting teeth 268 can interlock with each other, forming a mechanical locking effect between the extrusion plate 266 and the slider 240, effectively limiting the relative sliding between the two, thereby ensuring the stability and safety of the equipment operation.

[0044] In some embodiments of the present invention, reference is made to... Figure 7 and Figure 8 As shown, the locking structure 270 includes a limiting block 271, a second spring 272, an inner ring 273, an inner ring limiting protrusion 274, an outer ring 275, a limiting slider 276, a load-bearing plate 277, and a third spring 278. The outer ring 275 is installed on the top of the top plate 250, and the inner ring 273 is fixedly installed on the bottom of the walking mechanism 300 and is concentrically set with the outer ring 275. The concentric setting can ensure that the movement trajectory of each component of the locking structure 270 is accurate during operation and avoid jamming caused by eccentricity. The limiting block 271 is slidably installed in the groove at the top of the top plate 250 to ensure that the limiting block 271 can only slide in the vertical direction. The lifting column 263 is inserted upward into the bottom of the limiting block 271, which can drive the limiting block 271 to move up and down. The second spring 272 is installed between the limiting block 271 and the lifting column 263. Its function is to provide elastic restoring force. When the limiting block 271 is restricted by the limiting slider 276, it is compressed by the rising lifting column 263. At this time, the second spring 272 stores elastic potential energy. When the restricting force is removed, the second spring 272 can push the limiting block 271 to reset. Multiple inner ring limiting protrusions 274 are provided and fixedly installed on the outside of the inner ring 273. The limiting slider 276 slides through the outer ring 275 and inserts into the inner ring 273. The height and width of each inner ring limiting protrusion 274 are designed according to actual needs to ensure the fitting accuracy with the limiting slider 276 and are fixedly installed on the outside of the inner ring 273. The setting of these protrusions can guide the movement direction of the limiting slider 276 and limit the limiting slider 276 at a specific position. The bearing plate 277 is fixedly installed on the outside of the limiting slider 276 and located on the outside of the outer ring 275. The two ends of the spring 278 are connected to the outer ring 275 and the bearing plate 277 respectively. The spring 278 is used to maintain the relative positional relationship between the bearing plate 277 and the outer ring 275 to ensure the stability and reliability of the entire mechanical device during operation.

[0045] The working method of this invention: When waves crash in, they push the wave-damping plate 281 to move, causing the wave-damping plate 281 to drive the trapezoidal block 282 and gear plate 284 to slide synchronously. As the gear plate 284 slides, it also drives another set of wave-damping plates 281 and trapezoidal blocks 282 to slide synchronously. The sliding of the wave-damping plate 281 also activates the reset device 286 to store energy. When the trapezoidal block 282 is misaligned with the floating plate 261, the floating plate 261, under the action of buoyancy, drives the lifting column 263 to rise. As the lifting column 263 rises, it drives the swing arm 265 to swing and compress the first spring, causing the first spring to store energy. 5. During the swing, the extrusion plate 266 is pushed to move towards the slider 240, and the two sets of limiting teeth 268 are interlocked to lock the lifting and lowering of the belt conveyor 100. At the same time as the lifting and lowering of the belt conveyor 100 is locked, the lifting column 263 rises and pushes the limiting block 271 to rise, so that the limiting block 271 contacts the outer side of the limiting slider 276, restricting the sliding of the limiting slider 276. The limiting slider 276 cooperates with the inner ring limiting protrusion 274 to restrict the rotation of the belt conveyor 100 and the head support mechanism 200, preventing the belt conveyor 100 from deflecting under the impact of waves.

[0046] After the waves pass, the reset device 286 pushes the wave-damping plate 281 and the trapezoidal block 282 to reset. The spring pushes the lifting column 263 to descend. When the trapezoidal block 282 resets, it will squeeze the floating plate 261 to descend, so that the floating plate 261 and the spring drive the lifting column 263 to descend synchronously. The lifting column 263 drives the swing arm 265 to pull the squeezing plate 266 away from the slider 240, so that the two sets of limit teeth pressure 268 are misaligned. At the same time, the lifting column 263 drives the limit block 271 to descend, so that the limit block 271 and the limit slider 276 are misaligned and locked.

[0047] Furthermore, the larger the wave, the longer its wavelength and the longer its wave period. The wavelength of the wave that can move the wave baffle 281 is greater than the width of the belt conveyor 100, providing time for the height adjustment of the belt conveyor 100 within the wave period.

[0048] When the conveyor belt 100 needs to be adjusted, wait until the waves are small, then start the winch 500. The winch 500 will drive the conveyor belt 100 and the top plate 250 to rotate. While the conveyor belt 100 is rotating, the inner ring limiting protrusion 274 will first press the limiting slider 276 against the limiting block 271, causing the lower surface of the limiting slider 276 to contact the limiting block 271, thus restricting the rising of the limiting block 271. (If the limiting block 271 rises prematurely to restrict the sliding of the limiting slider 276, the winch 500 can be stopped and restarted after the limiting block 271 resets. Because there is room for movement between the upper surface of the limiting block 271 and the lower surface of the limiting slider 276, and the outer side of the limiting slider 276 is adjacent to the limiting block 271...) The outer sides of 71 are almost on the same axial plane. When the limiting block 271 and the limiting slider 276 slide synchronously, the limiting slider 276 restricts the rise of the limiting block 271 (releasing the lock on the rotation of the belt conveyor 100), allowing the inner ring 273 and the outer ring 275 to rotate relative to each other, adjusting the transport direction of the belt conveyor 100. During the adjustment process, the rising column 263 will compress the second spring 272, providing space for the rising column 263. At the same time, when the limiting slider 276 slides, it will also stretch the third spring 278, allowing the third spring 278 to store force. After rotating to a specific angle, the third spring 278 will push the limiting slider 276 to reset and cooperate with the inner ring limiting protrusion 274, releasing the restriction on the limiting block 271.
