Description

TECHNICAL FIELD

[0002] Shipbuilding engineering is a typical heavy equipment manufacturing field, and its core operation links involve a large number of different types and specifications of workpiece transfer, including steel pipes, special-shaped steel components, deck plates of different thicknesses, side plate materials, etc. The existing hoisting and conveying equipment has single fixed adaptability, and is mostly in the form of hooks or binding, which cannot be compatible with multiple types of workpieces. In the process of hoisting a long workpiece, if the binding position cannot be positioned at the middle of the workpiece, it is easy to cause uneven stress on both ends, and the longer end is easy to drop due to its high gravity, and the shorter end is stressed to rise, thereby causing the two ends to tilt and fall off. Secondly, the pipe diameters are different, and the binding is complicated and prone to accidents. For some special-shaped workpieces, binding is even more difficult, and if plate materials are conveyed, binding cannot provide sufficient fixing force. If synchronous hoisting is superimposed, the binding ropes are easy to deform or damage the edges of the bottom plate due to the superimposed gravity, and the existing large equipment is also not easy to move and carry workpieces on the ship body.

[0013] Compared with the prior art, the present application has the following advantages: 1. The present application breaks through the limitation through structural design, realizes full coverage and adaptation to mainstream workpieces in shipbuilding; for pipe fittings / irregular pieces; the first clamping structure adjusts the distance between the clamping arms through the screw rod and the self-adapting shape of the clamping assembly, which can manually rotate the screw rod to change the relative distance of the L-shaped clamping arms, adapt to workpieces of different widths, and can also be adjusted through the shaft rod and the side tooth ratchet to ensure that different diameter pipes (such as marine steel pipes) and different shaped irregular pieces (such as cabin wall support pieces) can be stably clamped without the need to replace special clamps.

[0014] 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.

[0015] 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.

[0016] 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

[0028] As a preferred solution, the clamping unit 94 further includes a clamping seat 941, a blocking seat 942, a force rod 943, a blocking piece 944 and a third spring 945.

Then, after the plate is inserted between the clamping seats 941, the plate is subjected to gravity downward. Since the plate thickness is filled between the clamping seats 941, the clamping seats 941 are limited from being reversely turned by force, thereby realizing self-adaptation of the clamping seats 941 to clamping plates of different thicknesses.

[0029] More specifically, the clamping unit 94 breaks through the limitation of manual distance adjustment of traditional plate clamping devices through the self-adaptive design without adjustment, can adapt to the clamping needs of multiple thickness plates in shipbuilding, and can ensure the lifting stability through the rubber anti-skid layer and gravity self-locking, while avoiding damage to the plate, fully meeting the efficient and safe operation requirements of shipbuilding site.

[0030] Working principle: The device moves through the wheels 6 on the lower wall of the vehicle body 1. When the device is in use, the device is powered on, the motor 4 is started, the gear box 5 is driven, the winding roller 2 is rotated, the steel wire 3 is retracted and extended, and the steel wire 3 is guided through the guide wheels 76 in the lifting support structure 7. By starting the first hydraulic cylinder 73 on the support arm 71 to extend, the lifting arm 72 is turned upward and raised, and the second hydraulic cylinder 74 is started to extend, the telescopic arm 75 is extended from the lifting arm 72, the overall support length is increased, and the support height is changed. Further, the steel rope 3 passes through the two guide wheels 76, drives the first clamping structure 8 to lift; when lifting and carrying a long workpiece, the first clamping structure 8 at the bottom is used, then the hand holds the handrail 84 on the first clamping arm 81 to exert force, thereby rotating the screw rod 83, forcing the second clamping arm 82 to move in the sliding groove 10 of the first clamping arm 81, and further changing the relative distance between the two clamping assemblies 88; the overall gravity is shared by the four symmetrically arranged force ropes 87, and is connected and converged with the steel rope 3 through the adapter ring 86; the stability of the first clamping arm 81 and the second clamping arm 82 is realized; When clamping, the second clamping arm 82 moves under the force of the screw rod 83, promoting the relative movement of the two clamping assemblies 88 for clamping; the several clamping rods 882 arranged on the clamping box 881 are in contact with the workpiece under force, thereby shrinking into the clamping box 881, and self-adapting to the size and irregular shape of the workpiece; after loosening, the clamping rod 882 is reset under the action of the first spring 883; When clamping a long pipe, the pipe ends are prevented from tilting, so that the one-way rotation direction of the clamping box 881 can be selected, for example, the clamping box 881 is limited by the side tooth ratchet 886 on the shaft rod 884 and the side tooth ratchet 886 on the first clamping arm 81 or the second clamping arm 82, and can only rotate clockwise to the right, but cannot rotate to the left, so that the clamping pipe part can be positioned and clamped to the right of the pipe, and the positioning distance of the left end of the pipe relative to the right end is longer, so that the left end of the pipe is heavier and exerts force to the left, thereby using the limiting of the side tooth ratchet 886 to prevent tilting; If small workpieces are clamped, especially after lifting, positioning and butt joint can be performed, the clamping box 881 can be rotated for adjustment, and during rotation, the side tooth ratchet 886 on the shaft rod 884 is driven to rotate by the force slot 11, and because of the one-way design of the inclined teeth of the side wall, the side tooth ratchet 886 on the shaft rod 884 moves along the force slot 11, realizes the tooth rotation of the two side tooth ratchets 886, and is re-engaged by the action force of the second spring 885, realizing the same single rotation angle; When the plate needs to be carried, the mounting seat 91 in the second clamping structure 9 is inserted into the clamping seat 941 at both ends, and is fixed by rotating and connecting the installation screw rod 93; Then the plate is stood up, the second clamping structure 9 is lowered, the symmetrically arranged semicircular clamping seats 941 are lowered, the plate end is inserted between the clamping seats 941 and passes upward, the clamping seat 941 is flipped open by the force of the eccentric part of the movable connection, and during the flipping process, the other end of the clamping seat 941 flips and moves, driving the force rod 943 in the clamping unit 94 to move upward and flip, the force rod 943 passes through the stop seat 942 during the flipping process, thereby compressing the third spring 945 between the stop seat 942 and the stop piece 944 to store force; After the plate passes through the clamping seat 941, the second clamping structure 9 can be lifted, and the two side walls of the plate contact the clamping seat 941 to apply downward force, drive the clamping seat 941 to relatively overturn, and promote the clamping seat 941 to always adhere to the plate by the reverse force of the third spring 945. Since the plate has a thickness, the thickness of the plate fills between the clamping seats 941 of the arc-shaped wall surface, so that the clamping seat 941 cannot relatively rotate and reset, thereby realizing the effect of gravity self-locking, and further adaptively clamping plates of different thicknesses for lifting and conveying. After the plate is conveyed, if it needs to be unlocked, the clamping seat 941 can be reversely overturned by manually pulling the connecting rod 95 to open the space between the clamping seats 941.

[0031] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Other modifications or functional replacements of the technical solutions of the present application made by those skilled in the art should be covered in the scope of the claims of the present application as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
