Description

Technical Field

[0001] The invention belongs to the technical field of lifting machinery, and in particular relates to a safety cable-operated device for special-shaped components. Background Art

[0002] When carrying out hoisting construction in strong wind and wave sea areas, due to the influence of wind and waves, the hull itself shakes greatly, and the hook swings greatly during hoisting. When the personnel are operating the rope, they are very likely to be thrown down by the hook, or even collide, causing safety accidents. For super-heavy components, the diameter of the steel cable required for hoisting is large and cannot be bent by human power, and the structure of the special-shaped components themselves is complex and difficult to operate. The usual way of operating the rope is to fix the steel cable in a ring in advance, and during the swinging process of the hoisting device, the position of the steel cable ring is adjusted by manpower in a small amount, and the overweight special-shaped component is quickly stretched while the hoisting device is hoisted. Its operation method is highly dangerous. At the same time, the hoisting position of the steel cable is highly random, and the ability of human control is extremely limited. It is mostly luck to hoist the overweight special-shaped components, and the construction efficiency is low, especially the hoisting of the twist king block of the breakwater is the most typical. Therefore, there is an urgent need for a special-shaped component safety cable operating device that is flexible in operation, strong in adaptability, accurate in the hoisting position of the steel cable, and ensures the safety of the operator and high in construction efficiency.

[0032] See also Figure 1 , Figure 1The structural schematic diagram of the safety cable device for special-shaped components of the present invention. A safety cable device for special-shaped components includes a hook 9, a housing 1, a winch 2, a chain 3 and a steel cable 4. The top of the housing 1 is provided with a first opening 11, and the bottom thereof is provided with a housing base 12, and the housing base 12 is provided with a second opening 13.

The housing base 12 is provided with an unlocking mechanism 7 for clamping or releasing the interface mechanism 6 and for releasing the clamping effect of the interface mechanism 6 on the joint 5. One end of the chain 3 with the joint 5 can pass through the first opening 11 and the second opening 13, and then be wound around the special-shaped component 10 to be hoisted along a predetermined track, and then the joint 5 is clamped by the interface mechanism 6, and then the chain 3 is pulled by the winch 2, thereby driving the steel cable 4, and the steel cable 4 can be wound around the hoisted special-shaped component 10 along the predetermined track, and then the interface mechanism 6 is clamped by the unlocking mechanism 7 and the clamping effect of the interface mechanism 6 on the joint 5 is released, completing the cable operation of the steel cable 4. The function of the chain 3 is to pull the steel cable 4, and the required pulling force is not large, so a small and easy-to-bend chain 3 can be used, and the chain 3 can be operated very conveniently by manpower.

[0033] Please refer to Figure 2 , Figure 2 The structure diagram of the interface mechanism in the safety cable device for special-shaped components of the present invention. In one embodiment, the interface mechanism 6 includes an interface base 61, a buckle 62 and an elastic device 63. One end of the interface base 61 is fixedly connected to the steel cable 4, and the other end is provided with a mounting plate 611. The number of mounting plates 611 is two or more. The mounting plates 611 are evenly arranged along the outer circumference of the interface base 61. The number of buckles 62 is the same as the number of mounting plates 611 and corresponds to each other. The buckles 62 are hinged to the corresponding mounting plates 611. The elastic device 63 applies elastic force to the buckles 62 to keep the buckles 62 rotating inwardly to clamp the joint 5. The joint 5 is inserted between the buckles 62. Under the action of the elastic device 63, the buckles 62 keep rotating inwardly to abut against the joint 5, so that the joint 5 is clamped by two or more buckles 62, ensuring the clamping and fixing effect of the interface mechanism 6 on the joint 5. In one embodiment, the elastic device 63 includes a plurality of torsion springs corresponding to the plurality of buckles 62, each of which is disposed between the corresponding buckle 62 and the mounting plate 611. The number of torsion springs is the same as the number of buckles 62 and the mounting plate 611, each torsion spring is disposed on the hinge shaft of the corresponding buckle 62, and the torsion spring is pre-stressed to keep the buckle 62 rotating inwardly, so that the plurality of buckles 62 are respectively subjected to force by the plurality of torsion springs, so that the plurality of buckles 62 are closed inwardly.

[0034] Please refer to Figure 3 , Figure 3The schematic diagram of the structure of the joint in the safety cable device for special-shaped components of the present invention. In one embodiment, in order to ensure that the plurality of buckles 62 clamp and fix the joint 5, the joint 5 is in the shape of an arrow, and wings 51 are respectively provided on both sides of the arrow. The joint 5 is connected to the chain 3 through the connecting rod 8. The width of the connecting rod 8 is smaller than the width of the wing 51. The end of the wing 51 close to the connecting rod 8 is provided with a first barb 511. The end of the buckle 62 away from the mounting plate 611 is provided with a clamping protrusion 622. The end of the clamping protrusion 622 close to the mounting plate 611 is provided with a second barb 6221 that matches and hooks with the first barb 511. The buckle 62 is provided with a clamping protrusion 622. When the winch 2 pulls the chain 3, the wing 51 of the joint 5 abuts against the clamping protrusion 622, and the first barb 511 and the second barb 6221 are mutually buckled, ensuring that the joint 5 will not be separated from the plurality of buckles 62, thereby ensuring the clamping and fixing effect of the interface mechanism 6 on the joint 5. In one embodiment, in order to facilitate the insertion of the connector 5 into the interface mechanism 6, the end of the clamping protrusion 622 away from the mounting plate 611 is provided with an arc chamfer. When in use, the connector 5 only needs to be pushed against the arc chamfer of the clamping protrusion 622 to push open the closed buckles 62. After the connector 5 passes over the clamping protrusion 622 on the buckle 62, the buckles 62 close and clamp the connector 5 again under the action of the torsion spring. At this time, the chain 3 can be pulled by the winch 2 to drive the steel cable 4. In one embodiment, in order to make the interface base 61 and the steel cable 4 more firmly fixed, a mounting sleeve 613 is provided on the interface base 61, and the end of the steel cable 4 away from the housing base 12 is inserted into the mounting sleeve 613 and fixed by welding.

[0035] Please refer to Figure 4 and Figure 5 , Figure 4 Schematic diagram of the clamping joint of the interface mechanism in the safety cable device for special-shaped components of the present invention, Figure 5The schematic diagram of the unlocking mechanism and the interface mechanism in the safety cable device for special-shaped components of the present invention. In one embodiment, the end of the buckle 62 close to the mounting plate 611 is bent outward to form a paddle 621, and the unlocking mechanism 7 includes two push-pull devices 71 and fixed baffles 72 corresponding to the two push-pull devices 71. Each push-pull device 71 and the corresponding fixed baffle 72 are respectively located on opposite sides of the second opening 13 and are both arranged on the housing base 12. The push-pull directions of the two push-pull devices 71 are arranged vertically. The end of the push-pull device 71 close to the corresponding fixed baffle 72 is provided with a movable baffle 73. The push-pull device 71 can push or pull the movable baffle 73 so that the movable baffle 73 and the corresponding fixed baffle 72 clamp or release the interface base 61. When the movable baffle 73 and the corresponding fixed baffle 72 clamp the interface base 61, the movable baffle 73 and the fixed baffle 72 respectively apply force to the corresponding paddle 621, so that the buckle 62 rotates outward to release the clamping effect on the joint 5. The angle formed between the buckle 62 and the paddle 621 is an obtuse angle. In this embodiment, preferably, the number of the buckles 62 is three or four. When the chain 3 drives the interface mechanism 6 to enter the interior of the housing 1 from the second opening 13, the unlocking mechanism 7 located inside the housing 1 is activated, and the movable baffle 73 is pushed to move toward the corresponding fixed baffle 72 through the push-pull device 71, and the interface base 61 is clamped by the movable baffle 73 and the fixed baffle 72 to achieve the clamping of the interface mechanism 6. At the same time, the movable baffle 73 and the fixed baffle 72 respectively apply force to the corresponding paddle 621, so that the paddle 621 rotates toward the corresponding mounting plate 611, thereby driving the buckle 62 to rotate outward through the paddle 621 to release the clamping effect of the buckle 62 on the joint 5, and the chain 3 can be pulled out at this time. And through the clamping effect of the unlocking mechanism 7 on the interface mechanism 6, the housing 1 can be used as a hoisting device for hoisting the special-shaped component 10, which is used to connect with the lifting machinery to complete the hoisting of the special-shaped component 10. The push-pull device 71 can be a cylinder. In one embodiment, the movable baffle 73 and the fixed baffle 72 are both L-shaped, and the horizontal sections of the two are close to each other, and the outer wall of the interface base 61 extends outward to form a supporting convex edge 612. When the movable baffle 73 and the fixed baffle 72 cooperate to clamp the interface base 61, the supporting convex edge 612 abuts against the vertical section of the fixed baffle 72, the horizontal section of the fixed baffle 72, the vertical section of the movable baffle 73 and the horizontal section of the movable baffle 73, respectively, so that the fixed baffle 72 and the movable baffle 73 are more stable when clamping the interface base 61, and the horizontal section of the fixed baffle 72 and the horizontal section of the movable baffle 73 can provide support force for the supporting convex edge 612, so as to avoid the interface mechanism 6 from being separated from the unlocking mechanism 7 when hoisting the special-shaped component 10, resulting in the failure of hoisting the special-shaped component 10. In one embodiment, in order to facilitate the connection between the shell 1 and the lifting machinery, the present invention also includes a hook 9, which is fixed to the top of the shell 1.After the lifting is completed, the movable baffle 73 is pulled away from the fixed baffle 72 by the push-pull device 71, and the movable baffle 73 is separated from the contact with the interface base 61, thereby releasing the lock on the interface mechanism 6. At this time, the shell 1 can be lifted by the lifting equipment, so that the steel cable 4 can be pulled out of the special-shaped component 10.

[0036] In one embodiment, there are two mounting plates 611, and one end of the buckle 62 close to the mounting plate 611 is bent outward to form a paddle 621. The unlocking mechanism 7 includes a push-pull device 71 and a fixed baffle 72. The push-pull device 71 and the fixed baffle 72 are respectively located on opposite sides of the second opening 13 and are both arranged on the shell base 12. An active baffle 73 is provided at one end of the push-pull device 71 close to the fixed baffle 72. The push-pull device 71 can push or pull the active baffle 73 so that the active baffle 73 and the fixed baffle 72 clamp or release the interface base 61. When the active baffle 73 and the fixed baffle 72 clamp the interface base 61, the active baffle 73 and the fixed baffle 72 respectively apply force to the two paddles 621 so that the buckle 62 rotates outward to release the clamping effect on the connector 5. When there are two mounting plates 611 and two buckles 62, the unlocking mechanism 7 can use only one push-pull device 71 and one fixed baffle 72, which can save costs while realizing that the unlocking mechanism 7 clamps or loosens the interface mechanism 6 and that the unlocking mechanism 7 releases the clamping effect of the interface mechanism 6 on the connector 5.

[0037] The working process of the present invention is briefly described below:

[0038] Before hoisting, the present invention is placed on the deck of the ship as a whole to prevent it from shaking in the air and causing installation accidents. The end of the chain 3 provided with the connector 5 is passed through the first opening 11 and the second opening 13 in sequence, and then the special-shaped component 10 to be hoisted is pulled along the predetermined track. After the chain 3 is pulled, the connector 5 on the chain 3 is inserted into the interface mechanism 6, so that the buckle 62 clamps the connector 5, and the first barb 511 and the second barb 6221 match and hook each other. Then the chain 3 is pulled by the winch 2, and the chain 3 drives the steel cable 4, and the steel cable 4 can move along the track of the chain 3 on the special-shaped component 10, so that the steel cable 4 can pull the special-shaped component 10 to be hoisted along the predetermined track. Continue to pull the steel cable 4 until the interface mechanism 6 enters the interior of the housing 1 from the second opening 13. Then, by controlling the push-pull device 71, the movable baffle 73 is pushed to move toward the fixed baffle 72, and the upper parts of the movable baffle 73 and the fixed baffle 72 press the paddle 621, and a force is applied to the paddle 621 to make the paddle 621 rotate toward the mounting plate 611, so that the paddle 621 drives the buckle 62 to rotate outward and open, thereby releasing the clamping effect of the interface mechanism 6 on the joint 5. At this time, the chain 3 can be pulled out of the interface mechanism 6 by the winch 2 to complete the cable clamping of the special-shaped component 10.

[0039] In the process of the unlocking mechanism 7 releasing the clamping effect of the interface mechanism 6 on the joint 5, the interface base 61 is clamped by the movable baffle 73 and the fixed baffle 72, and the horizontal sections of the movable baffle 73 and the fixed baffle 72 abut against the supporting convex edge 612, providing support force to the interface base 61, so that the end of the steel cable 4 provided with the interface mechanism 6 is also fixed on the shell base 12, and the present invention can be used as a hoisting device for hoisting the special-shaped component 10, and the hook 9 on the shell 1 is connected to the lifting machinery to carry out the hoisting operation. After the hoisting operation is completed, the push-pull device 71 is controlled to pull the movable baffle 73 away from the fixed baffle 72, and the interface mechanism 6 can be separated from the shell base 12 under the action of gravity, and the special-shaped component 10 is unlocked to complete the hoisting.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) First, the chain 3 is wound around the special-shaped component 10 to be hoisted along a predetermined track, and the joint 5 is clamped by the interface mechanism 6, and then the steel cable 4 can be pulled by the winch 2 to pull the special-shaped component 10 to be hoisted along the predetermined track. The chain 3 pulling the steel cable 4 is relatively thin and easy to pull and operate by manpower. The efficiency of setting the rope path is high, which improves the construction efficiency;

[0042] (2) Since the manual pulling chain 3 is flexible in operation and has strong applicability, it can be used for special-shaped components 10 of any shape;

[0043] (3) After the rigging work is completed, the interface mechanism 6 is clamped by the unlocking structure, and the clamping effect of the interface mechanism 6 on the joint 5 is released. At this time, the chain 3 can be withdrawn. The present invention can be used as a sling for hoisting the special-shaped component 10 without replacing another sling, thereby further improving the construction efficiency and reducing the engineering cost;

[0044] (4) Before lifting, the present invention is placed as a whole on the hull deck, avoiding the risk of safety accidents caused by shaking of conventional lifting equipment;

[0045] (5) The present invention has a simple structure, low cost and is suitable for promotion.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
