Description

Technical Field

[0001] This invention relates to the field of crane technology, specifically to a crane device for waterway construction. Background Technology

[0002] A floating crane is an engineering vessel specifically designed for lifting operations on water. Its applications are wide-ranging, including loading and unloading cargo in ports; salvage and rescue operations in maritime accidents; port construction, bridge building, and equipment installation in various harbor and near-shore marine engineering projects; and equipment outfitting and repair in shipyards. Small floating cranes (rated lifting capacity <16t) typically have a maximum lifting height between 20 and 40 meters.

[0003] For example, the anti-sway device for a floating crane, as disclosed in announcement number CN221876382U, includes: a lifting platform, with a winding device at the top of the lifting platform, and a hoisting rope passing through the top of the lifting platform; and a hook located at the bottom of the hoisting rope on the winding device. This anti-sway device, through the design of components such as a telescopic motor and a limiting plate, can effectively control the sway of the hoisting rope when the crane is lifting goods. Compared to existing devices, it can be adjusted according to the lower edge length of the hoisting rope and the amplitude of the sway, thus achieving a better anti-sway effect. By rotating the knobs on both sides of the plate, the threaded rod rotates, which pushes the moving plate to move inside the plate, thereby pushing the spring and increasing its thrust, further enhancing the anti-sway effect.

[0004] When a floating crane starts, brakes, or changes speed, the lifting equipment and the load being lifted will continue to maintain their original state of motion due to inertia, resulting in swaying relative to the main body of the crane. At the same time, when the center of gravity of the lifting equipment or the load shifts, or when the lifting rope is unevenly wound, the load and the lifting rope will also sway. The swaying that occurs when the crane lifting rope lifts the load will significantly reduce the safety, efficiency, and accuracy of the lifting operation, and may cause accidents. Summary of the Invention

[0005] The purpose of this invention is to provide a crane device for waterway construction, in order to solve the problem that the safety, efficiency and accuracy of lifting operations are significantly reduced when the center of gravity of the lifting equipment or the load shifts, or when the floating crane starts, brakes or changes speed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a crane device for waterway construction, comprising a crane body, a crane top and a cargo body, wherein a mounting plate is fixedly connected to one side of the bottom of the crane top; Also includes: The bottom of the mounting plate is provided with a stabilizing component, which includes a clamping unit and a spreading unit. The top of the top of the crane is fixedly connected to a top box. A lifting rope is wound inside the top box. A push plate is fixedly connected to the bottom of the lifting rope. A hook is fixedly connected to the bottom of the push plate. A fixing component is provided at the bottom of the hook. The clamping unit includes two active rods symmetrically rotatably connected inside the mounting plate. A gear is fixedly connected to the top of the active rod, and an arc-shaped push block is slidably installed on the outer side of the active rod.

[0007] Preferably, a protective cover is fixedly connected between the mounting plate and the top of the crane. A servo motor is fixedly installed at the bottom of the top of the crane. The output end of the servo motor is fixedly connected to the gear part on one side. A gear ring part is also rotatably connected to the top of the mounting plate. The inner teeth of the gear ring part mesh with the gear part on the other side. The outer teeth of the gear ring part mesh with the gear part on one side. An outer sliding sleeve is fixedly connected to the bottom of the mounting plate. An inner sliding sleeve is slidably installed at the bottom of the outer sliding sleeve. The outer sliding sleeve and the inner sliding sleeve are spaced apart. A clamping rod is slidably installed on the side wall of the outer sliding sleeve and the inner sliding sleeve.

[0008] By adopting the above technical solution, when starting, braking or changing speed, the servo motor drives the active rod to rotate, which can drive the clamping rod and clamping block to pop out step by step, so that the symmetrically distributed clamping blocks can clamp the two sides of the hoisting rope in sequence, reducing sudden start and stop during hoisting, thereby reducing the swing of the hoisting rope.

[0009] Preferably, a fixing ring is fixedly connected to the outer side of the inner sliding sleeve, a spring is sleeved on the outer side of the inner sliding sleeve, the bottom end of the spring is fixedly connected to the fixing ring, the top end of the spring is fixedly connected to the outer sliding sleeve, an inner groove is symmetrically opened on the inner wall of the outer sliding sleeve, and an inner slider is symmetrically fixedly connected to the outer side of the inner sliding sleeve, and the inner slider is slidably connected to the inner groove.

[0010] By adopting the above technical solution, as the hoisting rope is wound up, the hook will rise, the push plate will squeeze the bottom inner sliding sleeve, the inner sliding sleeve will drive the fixed ring to compress the spring, and the inner sliding sleeve will drive the inner slider to slide inside the inner groove.

[0011] Preferably, a contact plate is fixedly connected to the side of the abutting rod near the active rod, and a abutting block is fixedly connected to the end of the abutting rod near the suspension rope. A second spring is sleeved on the outer side of the abutting rod, one end of the second spring is fixedly connected to the inner wall of the outer or inner sliding sleeve, and the other end of the second spring is fixedly connected to the abutting block. A stepped vertical groove is provided on the outer side of the active rod, and a locking block is slidably connected inside the stepped vertical groove.

[0012] By adopting the above technical solution, when the outer and inner sliding sleeves slide, they will drive the clamping rods on them to move, and the arc-shaped push block will drive the locking block to slide inside the vertical groove of the step, so that the arc-shaped push block will always be flush with the contact plate.

[0013] Preferably, the locking block is fixedly connected to the inner ring of the arc-shaped push block, and a pushing end is integrally fixedly connected to one side of the arc-shaped push block. The upper pushing end will first squeeze the contact plate, and the lower pushing end will then squeeze the contact plate in sequence. Two limiting frames are fixedly connected in parallel to the side of the contact plate near the active rod, and the arc-shaped push block is located between the two adjacent upper and lower limiting frames.

[0014] By adopting the above technical solution, when the clamping rod moves up and down, it will drive the contact plate and the limiting frame to move, so that the limiting frame drives the arc-shaped push block to move up and down synchronously.

[0015] Preferably, the spreading unit includes two fixed cylinders fixedly connected to the bottom of the mounting plate. A guide rod is slidably connected to the bottom of the fixed cylinder. A base plate is fixedly connected to the bottom end of the guide rod. A spring three is sleeved on the outside of the guide rod. The top end of the spring three is fixedly connected to the fixed cylinder. The bottom end of the spring three is fixedly connected to the base plate. A flip plate is symmetrically rotatably connected to the bottom of the base plate.

[0016] By adopting the above technical solution, as the hoisting rope lifts the cargo body, the cargo body will squeeze the contact roller, the contact roller will drive the tilting plate to deflect and unfold, and the two contact rollers will stretch the spring between them, which will facilitate the compression and limiting of the top surface of the cargo body.

[0017] Preferably, two limiting plates are fixedly connected to the bottom of the base plate, the flip plate abuts against the limiting plates, a mounting frame is fixedly connected to the bottom end of the flip plate, a contact roller is rotatably connected inside the mounting frame, a spring is fixedly connected between the two flip plates on the same side, and a connecting rod is fixedly connected between the two mounting frames on different sides.

[0018] By adopting the above technical solution, the mounting frames on both sides of the connecting rod are deployed synchronously, thereby reducing the swaying of the lifting rope and the cargo body during lifting.

[0019] Preferably, the fixing component includes four collars fixedly installed at the four corners of the top of the cargo body, four tension ropes fixedly connected to the bottom of the push plate, and an auxiliary hook fixedly connected to the end of the tension rope away from the push plate.

[0020] By adopting the above technical solution, the four tension ropes around the perimeter are tightened simultaneously, keeping the hook and push plate in the center position and reducing the swaying caused by the shift of the center of gravity during subsequent hoisting.

[0021] Preferably, a drive motor is fixedly installed on the outside of the top box, and the output end of the drive motor passes through the top box and is fixedly connected to a winding drum. The winding drum is rotatably connected to the top box, and the hoisting rope is wound and fixed on the outside of the winding drum. The top of the crane and the inside of the mounting plate have vertically opened holes and slots, and the hoisting rope is slidably connected to the holes and slots.

[0022] By adopting the above technical solution, the drive motor will drive the drum to rotate, and the drum will wind up or unwind the lifting rope, which in turn lifts and transports the cargo.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a stabilizing component and utilizing the cooperation of the clamping unit and the spreading unit, the hoisting rope and the cargo body will swing during start-up, braking, or speed change. At this time, the servo motor drives the active rod to rotate, which can drive the clamping rod and clamping block to pop out step by step, so that the symmetrically distributed clamping blocks can clamp the two sides of the hoisting rope in sequence, reducing sudden start and stop during hoisting, thereby reducing the swing of the hoisting rope. Moreover, the clamping rod is slidably connected to the outer and inner sliding sleeves, which can adapt to the lifting and lowering of the hook to retract and expand. Thus, when the cargo body is hoisted, it can reduce the problem that the sway reduction structure with a long hoisting rope and fixed point has a relatively general sway reduction effect. At the same time, when lifting, the flip plate in the spreading unit will also unfold synchronously, thereby squeezing and limiting the top surface of the cargo body, keeping the cargo body stable, thereby further reducing the sway of the hoisting rope and the cargo body and improving the hoisting stability. The specific contents are as follows: By setting up a stabilizing component, after the hook is fixed to the cargo body, when the crane body lifts the cargo body, the drive motor will drive the drum to rotate, and the drum will wind or unwind the lifting rope. The lifting rope will lift and move the cargo body. During start-up, braking, or speed change, the lifting rope and the cargo body will swing. At this time, the servo motor will drive the gear part on one side to rotate, and the gear part will drive the gear part on the other side to rotate through the gear ring part. The gear part will drive the drive rod to rotate, and the two drive rods will rotate in opposite directions. The drive rod will drive the arc-shaped push block on it to rotate through the stepped vertical groove. The pushing end of the upper arc-shaped push block will first press the contact plate, and the pushing end of the lower arc-shaped push block will subsequently press the contact plate, so that multiple contact plates are pressed. The contact plates will drive the clamping rod and the clamping block to move, and the clamping block will stretch the spring. This design causes the upper and lower clamping blocks to pop out sequentially. The symmetrically distributed clamping blocks can sequentially clamp both sides of the lifting rope, reducing sudden starts and stops during lifting and thus reducing the swaying of the lifting rope. As the lifting rope is wound up, the hook will rise, and the push plate will press the lowest inner sliding sleeve. The inner sliding sleeve will drive the fixed ring to compress the spring, and the inner sliding sleeve will drive the inner slider to slide inside the inner groove. When the outer and inner sliding sleeves slide, they will drive the clamping rod on them to move. The clamping rod will drive the contact plate and the limiting frame to move. The limiting frame will drive the arc-shaped push block to move. The arc-shaped push block will drive the locking block to slide inside the step vertical groove, so that the arc-shaped push block will always be flush with the contact plate, maintaining stable driving and pressing on the contact plate. This is convenient for adapting to changes in lifting height and can reduce the swaying effect of the structure with a long lifting rope and fixed points. As the hoisting rope lifts the cargo body, the cargo body will squeeze the contact rollers. The contact rollers will cause the tilting plate to deflect and unfold. The two contact rollers stretch the spring four between them. The limiting plate limits the rotation of the subsequent contact rollers. The connecting rod keeps the mounting brackets on both sides unfolding synchronously. The bottom plate drives the guide rod to slide into the fixed cylinder. The bottom plate compresses the spring three, which can squeeze and limit the top surface of the cargo body, keeping the cargo body stable. This can further reduce the hoisting swing of the hoisting rope and the cargo body and improve the hoisting stability. By setting up a fixing component, the auxiliary hook passes through the first collar and is fixed to the adjacent second collar, making the tension rope V-shaped. Similarly, the remaining auxiliary hooks are fixed to the remaining collars, all in a V-shape, so that the four tension ropes around the perimeter are tightened synchronously, keeping the hook and push plate in the center position, keeping the cargo body stable and fixed, reducing the swaying caused by the center of gravity shift during subsequent lifting, and further improving the stability of lifting.

[0026] 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.

[0027] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a crane device for waterway construction, comprising a crane body 1, a crane top 2 and a cargo body 3, wherein a mounting plate 4 is fixedly connected to one side of the bottom of the crane top 2.

[0028] like Figure 1 and Figure 3 - Figure 13 As shown, a stabilizing component 5 is provided at the bottom of the mounting plate 4. The stabilizing component 5 includes a clamping unit and a spreading unit. A top box 7 is fixedly connected to the top of the crane top 2. A lifting rope 10 is wound and installed inside the top box 7. A push plate 11 is fixedly connected to the bottom of the lifting rope 10. A hook 12 is fixedly connected to the bottom of the push plate 11.

[0029] The clamping unit includes two active rods 52 that are symmetrically rotatably connected inside the mounting plate 4. A gear part 53 is fixedly connected to the top of the active rod 52, and an arc-shaped push block 516 is slidably installed on the outside of the active rod 52.

[0030] A protective cover 51 is fixedly connected between the mounting plate 4 and the top of the crane 2. A servo motor 54 is fixedly installed at the bottom of the top of the crane 2. The output end of the servo motor 54 is fixedly connected to a gear part 53 on one side. A gear ring part 55 is also rotatably connected to the top of the mounting plate 4. The inner teeth of the gear ring part 55 mesh with the gear part 53 on the other side, and the outer teeth of the gear ring part 55 mesh with the gear part 53 on one side, so that the active rods 52 on both sides rotate in opposite directions.

[0031] An outer sliding sleeve 56 is fixedly connected to the bottom of the mounting plate 4. An inner sliding sleeve 57 is slidably installed at the bottom of the outer sliding sleeve 56. The outer sliding sleeve 56 and the inner sliding sleeve 57 are spaced apart. A retaining rod 512 is slidably installed on the side wall of the outer sliding sleeve 56 and the inner sliding sleeve 57. The outer sliding sleeve 56 can be slidably stored in the inner sliding sleeve 57, thus adapting to hoisting and lifting use.

[0032] A fixing ring 58 is fixedly connected to the outer side of the inner sliding sleeve 57. A spring 59 is sleeved on the outer side of the inner sliding sleeve 57. The bottom end of the spring 59 is fixedly connected to the fixing ring 58, and the top end of the spring 59 is fixedly connected to the outer sliding sleeve 56. The inner wall of the outer sliding sleeve 56 is symmetrically provided with inner grooves 510. An inner slider 511 is symmetrically fixedly connected to the outer side of the inner sliding sleeve 57. The inner slider 511 is slidably connected to the inner groove 510.

[0033] A contact plate 513 is fixedly connected to the side of the clamping rod 512 near the active rod 52. A clamping block 514 is fixedly connected to the end of the clamping rod 512 near the suspension rope 10. A second spring 515 is sleeved on the outside of the clamping rod 512. One end of the second spring 515 is fixedly connected to the inner wall of the outer sliding sleeve 56 or the inner sliding sleeve 57. The other end of the second spring 515 is fixedly connected to the clamping block 514. A stepped vertical groove 517 is opened on the outside of the active rod 52. A locking block 518 is slidably connected inside the stepped vertical groove 517. The stepped shape of the stepped vertical groove 517 prevents the locking block 518 from coming out of the stepped vertical groove 517, which facilitates the subsequent sliding adjustment of the position of the arc-shaped push block 516.

[0034] The locking block 518 is fixedly connected to the inner ring of the arc-shaped push block 516. A pushing end 5161 is integrally fixedly connected to one side of the arc-shaped push block 516. The length of the upper arc-shaped push block 516 is greater than that of the lower arc-shaped push block 516, and the tail ends of all the arc-shaped push blocks 516 are in the same position. This makes it so that when the active rod 52 rotates, the upper pushing end 5161 will first press the contact plate 513, and then the lower pushing end 5161 will press the contact plate 513 in sequence.

[0035] Two limit frames 519 are fixedly connected in parallel on the side of the contact plate 513 near the active rod 52. The arc-shaped push block 516 is located between the two adjacent upper and lower limit frames 519. The limit frames 519 are used to drive the arc-shaped push block 516 to adjust its height.

[0036] The expansion unit includes two fixed cylinders 520 fixedly connected to the bottom of the mounting plate 4. A guide rod 521 is slidably connected to the bottom of the fixed cylinder 520. A base plate 522 is fixedly connected to the bottom end of the guide rod 521. A spring 523 is sleeved on the outside of the guide rod 521. The top end of the spring 523 is fixedly connected to the fixed cylinder 520. The bottom end of the spring 523 is fixedly connected to the base plate 522. A flip plate 525 is symmetrically rotatably connected to the bottom of the base plate 522.

[0037] Two limiting plates 524 are fixedly connected to the bottom of the base plate 522. The flip plate 525 abuts against the limiting plates 524. The bottom end of the flip plate 525 is fixedly connected to the mounting bracket 526. The mounting bracket 526 is rotatably connected to the inside of the mounting bracket 526. A spring 528 is fixedly connected between the two flip plates 525 on the same side. A connecting rod 529 is fixedly connected between the two mounting brackets 526 on different sides.

[0038] Among them, damping blocks are set at both ends of spring 1 59, spring 2 515, spring 3 523 and spring 4 528 to reduce their reciprocating vibration and maintain stable telescopic use.

[0039] Example 1: As Figure 1 - Figure 13As shown, after the hook 12 is fixed to the cargo body 3, when the crane body 1 lifts the cargo body 3, the drive motor 8 will drive the winding drum 9 to rotate. The winding drum 9 will wind or unwind the lifting rope 10, and the lifting rope 10 will lift and move the cargo body 3. When starting, braking or changing speed, the lifting rope 10 and the cargo body 3 will swing. At this time, the servo motor 54 will drive the gear part 53 on one side to rotate. The gear part 53 will drive the gear part 53 on the other side to rotate through the gear ring part 55. The gear part 53 will drive the drive rod 52 to rotate, and the drive rods 52 on both sides will rotate in opposite directions.

[0040] The active rod 52 drives the arc-shaped push block 516 on it to rotate through the stepped vertical groove 517. The pushing end 5161 of the upper arc-shaped push block 516 will first squeeze the contact plate 513, and the pushing end 5161 of the lower arc-shaped push block 516 will squeeze the contact plate 513 again, so that multiple contact plates 513 are squeezed. The contact plate 513 drives the clamping rod 512 and the clamping block 514 to move. The clamping block 514 stretches the second spring 515, so that the upper and lower clamping blocks 514 pop out step by step. The symmetrically distributed clamping blocks 514 can clamp the two sides of the hoisting rope 10 in sequence, reducing sudden start and stop during hoisting, thereby reducing the swing of the hoisting rope 10.

[0041] As the hoisting rope 10 is wound up, the hook 12 rises, and the push plate 11 presses against the lowest inner sliding sleeve 57. The inner sliding sleeve 57 drives the fixing ring 58 to compress the spring 59, and the inner sliding sleeve 57 drives the inner slider 511 to slide inside the inner groove 510. When the outer sliding sleeve 56 and the inner sliding sleeve 57 slide, they will drive the pressing rod 512 on them to move. The pressing rod 512 drives the contact plate 513 and the limiting frame 519 to move. The limiting frame 519 drives the arc-shaped push block 516 to move. The arc-shaped push block 516 drives the locking block 518 to slide inside the step vertical groove 517, so that the arc-shaped push block 516 will always be flush with the contact plate 513, maintaining stable driving and pressing on the contact plate 513. This is convenient for adapting to changes in hoisting height and can reduce the problem that the sway reduction structure of the long hoisting rope 10 and the fixed point has a relatively general sway reduction effect.

[0042] As the lifting rope 10 lifts the cargo body 3, the cargo body 3 presses against the contact roller 527. The contact roller 527 causes the tilting plate 525 to deflect and unfold. The two contact rollers 527 stretch the spring 528 between them. The limiting plate 524 limits the rotation of the subsequent contact roller 527. The connecting rod 529 keeps the mounting brackets 526 on both sides unfolding synchronously. The bottom plate 522 drives the guide rod 521 to slide into the fixed cylinder 520. The bottom plate 522 compresses the spring 523, thereby pressing and limiting the top surface of the cargo body 3, keeping the cargo body 3 stable, and thus further reducing the swaying of the lifting rope 10 and the cargo body 3 during lifting, and improving the lifting stability.

[0043] like Figure 1 , Figure 5and Figure 14 As shown, a fixing component 6 is provided at the bottom of the hook 12. The fixing component 6 includes four collars 61 fixedly installed at the four corners of the top of the cargo body 3. Four tension ropes 62 are fixedly connected to the bottom of the push plate 11. An auxiliary hook 63 is fixedly connected to the end of the tension rope 62 away from the push plate 11.

[0044] A drive motor 8 is fixedly installed on the outside of the top box 7. The output end of the drive motor 8 passes through the top box 7 and is fixedly connected to a winding drum 9. The winding drum 9 is rotatably connected to the top box 7. The hoisting rope 10 is wound and fixed on the outside of the winding drum 9. Vertical holes and slots are opened inside the top 2 of the crane and the mounting plate 4. The hoisting rope 10 is slidably connected to the holes and slots.

[0045] Example 2: Figure 14 As shown, the auxiliary hook 63 passes through the first collar 61 and is fixed to the adjacent second collar 61, making the tension rope 62 V-shaped. Similarly, the remaining auxiliary hooks 63 are fixed to the remaining collars 61, all in a V-shape, so that the four tension ropes 62 around the perimeter are tightened synchronously, keeping the hook 12 and push plate 11 in the center position, keeping the cargo body 3 stable and fixed, reducing the sway caused by the center of gravity shift during subsequent lifting, and further improving the stability of lifting.

[0046] Working principle: When using this device, firstly, as... Figure 1 - Figure 14 As shown, after the hook 12 is fixed to the cargo body 3, when the crane body 1 lifts the cargo body 3, the drive motor 8 will drive the winding drum 9 to rotate. The winding drum 9 will wind or unwind the lifting rope 10, and the lifting rope 10 will lift and lower the cargo body 3. During starting, braking, or speed change, the lifting rope 10 and the cargo body 3 will swing. At this time, the servo motor 54 will drive the gear part 53 on one side to rotate, and the upper and lower clamping blocks 514 will pop out step by step. The symmetrically distributed clamping blocks 514 can clamp the two sides of the lifting rope 10 in sequence, reducing sudden starts and stops during lifting, thereby reducing the swing of the lifting rope 10. As the lifting rope 10 is wound, the hook 12 will rise, and the inner sliding sleeve 57 will drive the inner sliding block 511. The inner groove 510 slides inside, making it easy to adapt to changes in lifting height. As the lifting rope 10 lifts the cargo body 3, the cargo body 3 will squeeze the contact roller 527. The contact roller 527 drives the tilting plate 525 to deflect and unfold. The two contact rollers 527 stretch the spring 4 528 between them. The limiting plate 524 limits the rotation of the subsequent contact roller 527. The connecting rod 529 keeps the mounting brackets 526 on both sides unfolding synchronously. The bottom plate 522 drives the guide rod 521 to slide into the fixed cylinder 520. The bottom plate 522 compresses the spring 3 523, thereby squeezing and limiting the top surface of the cargo body 3, keeping the cargo body 3 stable, and thus further reducing the lifting sway of the lifting rope 10 and the cargo body 3.
