Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to an adaptive conveying device for shipbuilding engineering. Background Technology

[0002] Shipbuilding engineering is a typical field of heavy equipment manufacturing. Its core operations involve the transfer of a large number of workpieces of different types and specifications, including steel pipes, special-shaped steel components, deck plates of different thicknesses, and side plates. Existing lifting and conveying equipment has limited adaptability and mostly uses hooks or binding methods, which cannot be compatible with multiple types of workpieces. Moreover, during the lifting of long workpieces, if the binding position is not positioned in the middle of the workpiece, it is easy to cause uneven force on both ends. The longer end is prone to sinking due to its own weight, while the shorter end is subjected to rising force, which can lead to tilting and easy detachment. Secondly, the different diameters of pipes make binding cumbersome and prone to accidents.

[0003] For some specially shaped workpieces, binding is even more difficult. If it is a conveying plate, binding cannot provide enough fixing force. If it is a stacked synchronous lifting, the binding rope is prone to deformation or damage to the edge of the bottom plate due to the superimposed weight. In addition, existing large equipment is not easy to move and transport workpieces on the hull. Summary of the Invention

[0013] Preferably, the other end of the steel rope passes through guide wheels and is guided by the guide wheels.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This solution overcomes this limitation through structural design, achieving full coverage and adaptation for mainstream workpieces in shipbuilding. For pipe fittings / irregular parts, the first clamping structure features a dual design of adjusting the clamping arm spacing with a screw rod and adaptive shape of the clamping components. This allows for manual rotation of the screw rod to change the relative distance of the L-shaped clamping arms, adapting to workpieces of different widths. Additionally, the telescopic clamping rod (in conjunction with the first spring) inside the clamping box can conform to the arc surface of the pipe fitting or the irregular contour of the irregular part. Furthermore, the angle of the clamping box can be adjusted via the shaft and side toothed ratchet, ensuring stable clamping of pipe fittings of different diameters (such as marine steel pipes) and irregular parts of different shapes (such as bulkhead supports) without the need to replace special clamps.

[0016] 2. For plates of different thicknesses, the detachable second clamping structure, when combined with the first clamping structure, utilizes a semi-circular eccentric clamp and gravity self-locking design, eliminating the need for manual adjustment of the clamp spacing. After the plate is inserted into the clamp, its own thickness limits the clamp's rotation range, while the downward gravity of the plate further compacts the clamp, preventing it from rotating relative to the clamp and thus self-locking. This design is suitable for deck plates and side plates of common thicknesses in shipbuilding, avoiding the problems of traditional clamps not clamping thick plates tightly and thin plates easily deforming.

[0017] 3. The clamping rod of the first clamping structure and the first spring form an elastic fit, which can tightly wrap the surface of the workpiece and avoid local slippage caused by rigid clamping; the gravity self-locking of the second clamping structure does not require additional power and can maintain the clamping force by relying only on the weight of the plate itself. Even if there is a sudden power failure, the clamp can still self-lock to prevent the plate from falling; the first clamping structure transmits the lifting force through two pairs of force-sharing ropes and a transition ring. The force-sharing ropes are led out from the upper wall of the first clamping arm at equal distances and converge at the transition ring, which can evenly distribute the weight of the workpiece to the steel rope and avoid the workpiece tilting or clamping arm deformation caused by single-point force; the guide wheel of the lifting support structure ensures the stability of the steel rope trajectory when it is retracted and extended, prevents the steel rope from deviating and causing the clamping structure to shake, and further ensures the balance of the workpiece during the lifting process.

[0018] 4. The elastic contact of the clamping rod in the first clamping structure and the arc-shaped contact of the semi-circular clamping seat in the second clamping structure both avoid the squeezing damage to the workpiece surface caused by traditional rigid clamps. This is especially suitable for alloy plates and thin-walled pipes with high precision requirements in shipbuilding, reducing workpiece loss during lifting. The clamping components in the equipment achieve unidirectional rotation of the clamping box through the symmetrical meshing design of the side tooth ratchet. When clamping pipes or long workpieces, for example, if the clamping box can only rotate clockwise, one end of the longer workpiece can be left longer and positioned on the opposite side of rotation. Then, the longer end is locked by its own gravity to prevent the two ends of the longer workpiece from tilting and falling off. Attached Figure Description

Detailed Implementation

[0028] The following will refer to the appendices in the embodiments of the present invention. Figures 1-8 For further details:

[0029] This invention provides a technical solution: an adaptive conveying device for shipbuilding engineering, comprising a vehicle body 1, a roller 2 mounted on the upper right wall of the vehicle body 1, a steel rope 3 wound on the roller 2, a motor 4 and a gearbox 5 connected to the front of the roller 2, and the roller 2 being driven by the motor 4 to the gearbox 5 for transmission; wheels 6 are mounted on the lower wall of the vehicle body 1 near the four corners; a support structure 7 is mounted on the upper left wall of the vehicle body 1 near the middle, one end of the steel rope 3 passing through the support structure 7, and a first clamping structure 8 connected to one end of the steel rope 3; a second clamping structure 9 is detachably mounted on the first clamping structure 8; the vehicle body 1 moves via the wheels 6, the power of the motor 4 is transmitted through the gearbox 5, and the motor 4 is protected, thereby driving the roller 2 to rotate and unload the steel rope 3; the first clamping structure 8 is used to fix pipes or irregularly shaped workpieces and can adapt to their shape; the second clamping structure 9 is used to adapt to clamping plates of different thicknesses.

[0030] As a preferred embodiment, the support structure 7 further includes a support arm 71, a boom 72, a first hydraulic cylinder 73, a second hydraulic cylinder 74, a telescopic arm 75, and a pair of guide wheels 76. One end of the support arm 71 is fixedly mounted on the upper wall of the vehicle body 1 and located to the left of the roller 2. The boom 72 is T-shaped, with one end of the boom 72 movably mounted on the other end of the support arm 71, and the boom 72 can rotate up and down on the support arm 71. The other end of the boom 72 is a T-shaped tubular structure. One end of the first hydraulic cylinder 73 is movably connected to the left side wall of the support arm 71, and the other end of the first hydraulic cylinder 73 is movably connected to the boom 72 near one end. The second hydraulic cylinder 74... The boom 75 is fixedly installed inside the other end of the boom 72. One end of the telescopic boom 75 is movably inserted into the other end of the boom 72, and one end of the telescopic boom 75 is connected to the telescopic end of the second hydraulic cylinder 74. One guide wheel 76 is movably installed on the upper wall of the other end of the telescopic boom 75, and the other guide wheel 76 is movably installed at the top center of one end of the boom 72. The height of the telescopic boom 75 can be adjusted by rotating the boom 72 on the support arm 71 through the first hydraulic cylinder 73. The telescopic boom 75 can be adjusted by extending and retracting through the second hydraulic cylinder 74. The steel rope 3 is guided by the guide wheel 76, and the other end of the steel rope 3 passes through the guide wheel 76 and is guided by the guide wheel 76.

[0031] More specifically, the lifting support structure 7 enables precise and stable adjustment of the lifting height and horizontal support length, while the guide wheel 76 ensures the smooth delivery of the steel rope 3, providing a reliable position adjustment basis for the subsequent clamping structure to stably lift the workpiece, which is especially suitable for the complex lifting space environment of shipbuilding sites.

[0032] As a preferred embodiment, the first clamping structure 8 further includes a first clamping arm 81, a second clamping arm 82, a spiral rod 83, a pair of handrails 84, a pair of sockets 85, an adapter ring 86, two pairs of force-shaping ropes 87, and a pair of clamping components 88. The first clamping arm 81 is L-shaped, and a groove 10 is formed in the middle of one end of the first clamping arm 81. The second clamping arm 82 is L-shaped, and one end of the second clamping arm 82 is movably inserted into the groove 10 at one end of the first clamping arm 81. The other end of the second clamping arm 82 corresponds to the other end of the first clamping arm 81. One end of the spiral rod 83 movably passes through the first clamping arm 81 and is located in the middle of the groove 10. The other end of the spiral rod 83 is movably screwed into one end of the second clamping arm 82. A rotating wheel is fixedly installed on one end of the spiral rod 83. A pair of handrails 84 are symmetrically arranged on the side wall of the first clamping arm 81 and close to the rotating wheel. A pair of sockets 85 are respectively connected to... The first clamping structure 8 is symmetrically positioned on both sides of the slide groove 10, with one end of the first clamping arm 81 located on the lower wall of the middle section. The adapter ring 86 is fixedly connected to the other end of the steel rope 3 and is located below the other end of the telescopic arm 75. One end of each pair of force-sharing ropes 87 is fixedly connected to the upper wall of the first clamping arm 81 at equal intervals, and the other end of each force-sharing rope 87 is relatively inclined and connected to the adapter ring 86. A pair of clamping components 88 are movably positioned at the middle of the other ends of the first clamping arm 81 and the second clamping arm 82, and the clamping components 88 are symmetrical to each other. By rotating the screw rod 83, the second clamping arm 82 is forced to move within the slide groove 10 of the first clamping arm 81, adjusting the relative distance between the two clamping components 88. The force-sharing ropes 87 distribute the weight and converge at the adapter ring 86. The adapter ring 86 is connected to the steel rope 3, and the height of the first clamping structure 8 is adjusted by the extension and retraction of the steel rope 3.

[0033] More specifically, the first clamping structure 8, through the design of adjusting the spacing with a screw rod 83, dispersing gravity with a force-sharing rope 87, and symmetrical clamping components 88, not only achieves the adaptable clamping of pipes of different widths or irregular workpieces, but also ensures the structural stability during the lifting process, providing a reliable clamping foundation for the safe and efficient transportation of complex-shaped workpieces in shipbuilding.

[0034] As a preferred embodiment, the clamping assembly 88 further includes a clamping box 881, a plurality of clamping rods 882, a plurality of first springs 883, a shaft 884, a second spring 885, and a pair of side-toothed ratchet wheels 886. The clamping box 881 is a rectangular box. One end of each of the clamping rods 882 equidistantly extends through the rear side wall of the clamping box 881. One end of each of the first springs 883 is fixedly connected to the other end of each of the clamping rods 882, and the other end of each of the first springs 883 is fixedly attached to the inner front side wall of the clamping box 881. One end of the shaft 884 is fixedly disposed in the middle of the front side wall of the clamping box 881, and the other end of the shaft 884 extends movably through the middle of the other end of the first clamping arm 81. The side wall of the shaft 884 is symmetrically provided with force-applying grooves 11. The second springs 885 are movably fitted onto the shaft 884. A side-toothed ratchet 886 is movably mounted on the shaft 884, and the inner side wall of the shaft hole of the side-toothed ratchet 886 is provided with a protrusion that matches the force-applying groove 11. The side-toothed ratchet 886 is attached to the second spring 885, and the side-toothed ratchet 886 can move on the shaft 884. Another side-toothed ratchet 886 is mounted on the other end of the shaft 884 and fixedly mounted on the other side wall of the first clamping arm 81. The pair of side-toothed ratchets 886 are meshed with each other and can rotate relatively unidirectionally through the shaft 884. Multiple clamping rods 882 are arranged by the clamping box 881, and the clamping rods 882 are stretched and contracted by the first spring 883 under force to achieve the shape of the object during clamping. The clamping box 881 can be rotated through the shaft 884, and unidirectional rotation is achieved by the side-toothed ratchet 886.

[0035] More specifically, the clamping assembly 88, through its passive elastic adaptation and active angle locking design, not only solves the problem of adapting irregular workpiece shapes in shipbuilding, but also ensures the stability of the lifting angle through the unidirectional side toothed ratchet 886, avoiding the risk of workpiece falling due to angle deviation during transportation. At the same time, the rubber anti-slip pad further protects the surface precision of the workpiece.

[0036] As a preferred embodiment, the second clamping structure 9 further includes a mounting base 91, a pair of mounting brackets 92, a pair of mounting screws 93, four pairs of clamping units 94, and a pair of connecting rods 95. The mounting base 91 is concave, and both ends of the mounting base 91 are detachably inserted into the socket 85. The pair of mounting brackets 92 are both portal frame structures, with their middle portions symmetrically arranged on the lower wall of the mounting base 91. The pair of mounting screws 93 respectively movably pass through the socket 85 and the mounting base 91, and the mounting screws 93 are screwed to the mounting base 91. The four pairs of clamping units 94 are symmetrically arranged on both ends of the mounting brackets 92, and the pair of connecting rods 95 are fixedly connected between the pair of clamping units 94. The second clamping structure 9 is connected to the socket 85 through the mounting base 91 and fixed by the mounting screws 93. The clamping units 94 are symmetrically arranged at both ends of the mounting brackets 92 to achieve synchronous start-up and clamping of the clamping units 94.

[0037] More specifically, the second clamping structure 9, through its detachable design, synchronous linkage 95, and gravity self-locking, not only achieves rapid switching with the first clamping structure 8, but also solves the pain points of traditional plate clamping devices such as "poor thickness adaptability and asynchronous operation". It is especially suitable for batch lifting operations of plates of various specifications in shipbuilding, ensuring the stability and efficiency of plate lifting.

[0038] As a preferred embodiment, the clamping unit 94 further includes a clamping seat 941, a stop 942, a force-bearing rod 943, a baffle 944, and a third spring 945. The clamping seats 941 are all semi-circular structures, with one end of each clamping seat 941 movably connected to one end of the mounting frame 92, and the clamping seats 941 are eccentrically positioned. One end of the stop 942 is movably connected to the side wall of the mounting frame 92, and the stop 942 is rotatable. Both ends of the connecting rod 95 are fixedly connected to one end of the force-bearing rod 943, one end of the force-bearing rod 943 movably passes through the middle of the stop 942, and the other end of the force-bearing rod 943 is movably connected to the other side wall of the clamping seat 941. The baffle 944 is fixedly fitted onto the clamping unit. On the force-bearing rod 943, and with the baffle 944 corresponding to the stop 942, the third spring 945 is movably fitted on the force-bearing rod 943, and the third spring 945 is located between the baffle 944 and the stop 942; through the semi-circular clamp 941 for movable eccentric setting, and the limiting connection of the force-bearing rod 943, the arc-shaped side wall of one end of the clamp 941 is kept relatively close by the force of the third spring 945, so that after the plate is inserted between the clamps 941, the plate is downward under gravity. Since the thickness of the plate is filled between the clamps 941, the relative rotation of the clamp 941 is restricted, so that the clamp 941 can adaptively clamp plates of different thicknesses.

[0039] More specifically, the clamping unit 94, through its non-adjustable adaptive design, breaks through the limitation of traditional plate clamping devices that require manual distance adjustment. It can not only adapt to the clamping needs of plates of various thicknesses in shipbuilding, but also ensures lifting stability through rubber anti-slip layer and gravity self-locking, while avoiding damage to the plates, fully meeting the requirements of efficient and safe operation on shipbuilding sites.

[0040] Working principle:

[0041] The equipment moves via wheels 6 on the lower wall of the vehicle body 1. When the equipment is in use, after powering on the equipment, the motor 4 can be started. After transmission through the gearbox 5, the roller 2 is driven to rotate, realizing the winding and unwinding of the steel rope 3. The steel rope 3 is guided by the guide wheel 76 in the support structure 7.

[0042] By activating the extension of the first hydraulic cylinder 73 on the outrigger 71, the boom 72 is tilted upward and raised, and by activating the extension of the second hydraulic cylinder 74, the telescopic boom 75 is extended from the boom 72, increasing the overall support length and thus changing the support height.

[0043] Then, after the steel rope 3 passes through the two guide wheels 76, it drives the first clamping structure 8 to move up and down. When lifting and transporting a long workpiece, the first clamping structure 8 is used as a guide, and the hand is held on the handle 84 on the first clamping arm 81 to rotate the screw rod 83. This causes the second clamping arm 82 to move within the groove 10 of the first clamping arm 81, thereby changing the relative distance between the two clamping components 88. The overall weight is distributed through four symmetrically arranged force-bearing ropes 87 and is connected to the steel rope 3 through the adapter ring 86, thus stabilizing the first clamping arm 81 and the second clamping arm 82.

[0044] When clamping, the second clamping arm 82 moves under the force of the screw rod 83, promoting the relative movement of the two clamping components 88 for clamping; the several clamping rods 882 arranged on the clamping box 881 come into contact with the workpiece and are subjected to force, thereby contracting into the clamping box 881 to adapt to the size and irregular shape of the workpiece; after being released, the clamping rods 882 are reset by the force of the first spring 883.

[0045] When clamping long pipe fittings, to prevent the two ends of the pipe fittings from tilting, the clamping box 881 can be positioned according to its unidirectional rotation direction. For example, if the clamping box 881 is limited by the engagement of the side toothed ratchet 886 on the shaft 884 with the side toothed ratchet 886 on the first clamping arm 81 or the second clamping arm 82, and can only rotate clockwise to the right but not to the left, the clamping part of the pipe fitting can be positioned and clamped to the right of the middle of the pipe fitting. As a result, the positioning distance of the left end of the pipe is longer than that of the right end, so the left end of the pipe is heavier and will exert force to the left. Then, by utilizing the limitation of the side toothed ratchet 886, it will be impossible to tilt.

[0046] If clamping smaller workpieces, especially if positioning and docking are required after lifting, the clamping box 881 can be rotated for adjustment. During rotation, the side-tooth ratchet 886 on the shaft 884 is driven to rotate by the force groove 11. Due to the unidirectional design of the helical teeth on the side wall, the side-tooth ratchet 886 on the shaft 884 is moved along the force groove 11 under force, realizing the disengagement and rotation of the two side-tooth ratchet 886, and re-engaging with the help of the second spring 885, so that the single rotation angle is the same.

[0047] When it is necessary to move the plate, the two ends of the mounting base 91 in the second clamping structure 9 can be inserted into the clamping base 941 and fixed by screwing the mounting screw 93 through;

[0048] Then the plate is erected, causing the second clamping structure 9 to descend, and the symmetrically arranged semi-circular clamps 941 are lowered. The end of the plate is inserted between the clamps 941 and passes upward. The clamps 941 are opened by force through the movable connection of the eccentric part. During the flipping process, when the other end of the clamps 941 flips and moves, it drives the force rod 943 in the clamping unit 94 to move upward and flip. During the flipping process, the force rod 943 will pass through the stop 942, thereby compressing the third spring 945 between the stop 942 and the baffle 944 to store force.

[0049] After the plate passes through the clamp 941, the second clamping structure 9 can be lifted. The two side walls of the plate then contact the clamp 941 and apply downward force, causing the clamp 941 to rotate relative to each other. With the help of the reverse force of the third spring 945, the clamp 941 and the plate remain in contact. Because the plate has thickness, the thickness of the plate fills the space between the curved walls of the clamp 941, preventing the clamp 941 from rotating relative to each other and returning to its original position. This achieves a gravity self-locking effect, thus adapting to the clamping and lifting of plates of different thicknesses. After the plate is transported, if unlocking is required, the connecting rod 95 can be manually pulled to rotate the clamp 941 in the opposite direction and open the space between the clamps 941.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Other modifications or functional substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
