[0042] Furthermore, the hook 8 is movably mounted on the hook mounting seat 9 , and the hook mounting seat 9 is fixedly mounted on the lifting connecting plate 7 .

[0044] Preferably, when performing the lifting operation, the first motor 15 mainly controls the first sling connecting roller 13 to be wound and released, so that the lifting rope 10 pulls the lifting wheel 47 on the lifting connecting plate 7 to complete the lifting operation at the hook 8, and the lifting operation is achieved with labor-saving lifting wheel 47 and the eighth limit guide wheel 49.
[0045] In addition, when performing lifting operations, the pitch angle at the connection between the second boom 6 and the first boom 4 is mainly controlled by the extension and retraction of the second hydraulic cylinder 17, and the pitch angle at the connection between the first boom 4 and the rotating base 3 is controlled by the extension and retraction of the first hydraulic cylinder 16, thereby well realizing the lifting and hoisting operations of the crane.
[0046] It should be particularly noted that the output shaft of the first motor 15 can be driven in forward and reverse directions and has a corresponding self-locking function.
[0047] Example 2
[0048] like Figures 1 to 9 As shown, based on Example 1, this embodiment further includes a sway reduction mechanism, which is installed on the lifting connecting plate 7 and located on the outside of the lifting sling 10, and is used to reduce the sway of the lifting of the lifting sling 10. The sway reduction mechanism includes a sway reduction cable 28 for opening the limit support, and the sway reduction cable 28 is transmission-connected to the lifting connecting plate 7. The lifting mechanism drives the sway reduction mechanism to perform sway reduction.
[0049] Furthermore, the anti-roll mechanism also includes a sixth limiting guide wheel 31 for limiting the opening of the traction of the anti-roll cable 28. The anti-roll cable 28 is connected to the lifting connecting plate 7 through a plurality of seventh limiting guide wheels 48. A fifth limiting guide wheel 29 for transmission limiting is also provided on one side of the seventh limiting guide wheel 48. The fifth limiting guide wheel 29 is rotatably mounted on the first guide wheel mounting seat 30. The first guide wheel mounting seat 30 is fixedly connected to the lifting connecting plate 7. The sixth limiting guide wheel 31 is rotatably connected to the second guide wheel mounting seat 32. The second guide wheel mounting seat 32 is limited and movably mounted on the first guide wheel mounting seat 30.
[0050] Furthermore, the anti-sway mechanism also includes a screw rod 33 for driving the sixth limit guide wheel 31 to open and limit, the second guide wheel mounting seat 32 is threadedly connected to the screw rod 33, the screw rod 33 is rotatably mounted in the first guide wheel mounting seat 30, the screw rod 33 is rotatably connected to the second connecting shaft 35 through the first synchronous belt 34, the second connecting shaft 35 is rotatably connected to the third connecting shaft 37 through the second synchronous belt 36, the second connecting shaft 35 is rotatably mounted on the first guide wheel mounting seat 30, and the third connecting shaft 37 is rotatably mounted inside the lifting connecting plate 7.
[0051] Furthermore, the anti-roll mechanism also includes a second gear 41 and a first gear 40 for driving the third connecting shaft 37 to rotate. The third connecting shaft 37 is connected to the fourth connecting shaft 39 through the rotation of the bevel gear pair 38. The fourth connecting shaft 39 is rotatably connected to the inside of the lifting connecting plate 7. The first gear 40 is fixedly connected to the fourth connecting shaft 39. The second gear 41 is meshedly connected to the first gear 40. The second gear 41 is rotatably installed in the inside of the lifting connecting plate 7 through the fifth connecting shaft 42. The diameter of the second gear 41 is larger than that of the first gear 40.
[0052] Furthermore, the anti-sway mechanism also includes a guide slider 43 and a spring 46 for driving the second gear 41 to rotate. The lifting wheel 47 is rotatably installed on the guide slider 43. The guide slider 43 is connected to the inside of the lifting connecting plate 7 by a guide rod 45 for limited sliding. A spring 46 is provided on one side of the guide slider 43, and a plurality of teeth 44 meshing with the second gear 41 are provided on the guide slider 43.
[0053] Preferably, in this embodiment, since the anti-rolling cable 28 is transmission-connected to the outside of the hoisting connection plate 7, and the traction processing of the hoisting at the hoisting connection plate 7 is realized under the limiting and guiding action of the seventh limiting guide wheel 48 and the fifth limiting guide wheel 29, and each time the hook 8 performs the hoisting processing, the second motor 24 controls the second sling connecting roller 25 to follow the first sling connecting roller 13 to perform synchronous release and contraction control, thereby realizing the synchronous traction of the anti-rolling cable 28 on the hoisting at the hoisting connection plate 7;
[0054] In addition, due to the conduction of the seventh limiting guide wheel 48, the anti-roll cable 28 is in a relatively stable traction state. Compared with the problem of poor stability of the traditional traction only through the hook, this structure achieves a better effect of stable traction and pulling and limiting.
[0055] In the normal state, when no lifting is performed, the guide slider 43 on the lifting wheel 47 is located at a lower position of the second gear 41 under the elastic action of the spring 46. When lifting is performed, the guide slider 43 compresses the spring 46 and moves toward the first guide wheel mounting seat 30. At this time, the second gear 41 is driven to rotate under the meshing connection relationship between the teeth 44 on the guide slider 43 and the second gear 41, and the second gear 41 drives the fourth connecting shaft 39 on the first gear 40 to rotate, so that the cone The rotational connection relationship of the gear pair 38 drives the third connecting shaft 37 to rotate, the third connecting shaft 37 drives the second connecting shaft 35 to rotate under the synchronous driving action of the second synchronous belt 36, and the second connecting shaft 35 drives the screw rod 33 to rotate under the synchronous driving action of the first synchronous belt 34, so that the sixth limiting guide wheel 31 is driven to move in the direction close to the anti-rolling cable 28 under the meshing connection relationship between the second guide wheel mounting seat 32 and the screw rod 33, thereby realizing the opening limit processing of the tight anti-rolling cable 28. Fig. 9 As shown, the hoisting connecting plate 7 is in a state of being pulled by the anti-sway cable 28, which greatly reduces the shaking of the hoisting at the hook 8, has a good anti-sway effect, and is convenient for the hoisting use of the crane.
[0056] Among them, since the diameter of the second gear 41 is larger than that of the first gear 40, the rotation distance of the screw rod 33 can be well controlled, and a good push limit processing is achieved at the sixth limit guide wheel 31, so that the anti-sway cable 28 is in a stretched and straightened state to reduce the swing during the lifting process.
[0057] It should be particularly noted that the screw rod 33 and the second connecting shaft 35 are both provided with pulleys synchronously connected to the first synchronous belt 34 , and the second connecting shaft 35 and the third connecting shaft 37 are both provided with pulleys synchronously connected to the second synchronous belt 36 .
[0058] Example 3
[0059] like Figure 1 to Figure 5 As shown, based on the above embodiments, this embodiment further includes a roll reduction control mechanism, which is installed on the outer side of the second lifting arm 6 and is used to control the roll reduction of the roll reduction cable 28. The roll reduction control mechanism includes an adjustment arm 19 and a telescopic arm 22 for roll reduction control. The adjustment arm 19 and the telescopic arm 22 are both installed on the outer side of the second lifting arm 6.
[0060] Furthermore, the anti-roll control mechanism also includes a second cable connecting roller 25 for pulling the anti-roll cable 28 for transmission. One end of the anti-roll cable 28 is connected to the telescopic arm 22, and the other end of the anti-roll cable 28 is tied to the second cable connecting roller 25. The telescopic arm 22 is also provided with a third limiting guide wheel 26 and a fourth limiting guide wheel 27 for limited transmission. The second cable connecting roller 25 is fixedly connected to the output shaft of the second motor 24, and the second motor 24 is fixedly installed on the outside of the telescopic arm 22.
[0061] Furthermore, the anti-sway control mechanism also includes a fourth hydraulic cylinder 23 for controlling the telescopic arm 22 to extend and retract, and a third hydraulic cylinder 21 for controlling the adjusting arm 19 to swing. The telescopic arm 22 is fixedly connected to the piston rod of the fourth hydraulic cylinder 23, and the fourth hydraulic cylinder 23 is fixedly installed inside the adjusting arm 19. The adjusting arm 19 is hingedly installed on the fixed seat 18 through the connecting rod 20, and the third hydraulic cylinder 21 is hingedly installed on the fixed seat 18. The piston rod of the third hydraulic cylinder 21 is hingedly installed on the adjusting arm 19, and the fixed seat 18 is fixedly installed on the second lifting arm 6.
[0062] Preferably, in this embodiment, the second motor 24 can control the second sling connecting roller 25 to tighten and release during the lifting process, and initially follow the first sling connecting roller 13 to tighten and release synchronously, thereby completing the synchronous traction process during the lifting process. When in the lifting state, the second motor 24 can control the second sling connecting roller 25 to perform fine-tuning during the traction process, so as to facilitate the anti-roll cable 28 to be in a taut state, thereby greatly reducing the shaking of the hook 8 during the lifting process;
[0063] And because the crane itself is installed on the ship, when the ship shakes, it is easy to cause the objects hoisted at the hook 8 to shake. Therefore, through the telescopic control of the fourth hydraulic cylinder 23 and the pitch adjustment control of the third hydraulic cylinder 21, the hoisting at the hook 8 on the hoisting connecting plate 7 can be made more balanced and stable, reducing the swaying during the hoisting process, and the anti-sway effect is good.
[0064] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.
[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
