Description

Technical Field

[0001] This invention relates to the field of wind turbine hoisting technology, and more specifically, to a controllable locking device for guy ropes used in wind turbine hoisting. Background Technology

[0002] Wind turbine hoisting is a large-scale high-altitude hoisting operation. When hoisting components such as towers and nacelles, guy ropes are needed to control their posture and prevent swaying.

[0003] Currently, the industry commonly uses a shackle-wrapping method to control guy ropes. This involves using a standard shackle as the fixing and control component for the guy rope, wrapping the guy rope twice around the shackle, and relying on the friction between the rope and the shackle to achieve fixation; when the rope is loosened, multiple people pull on the rope, and when it is tightened, it is rewound.

[0004] However, this control method requires workers to touch the guy ropes with their bare hands. This means that when the guy ropes need to be stopped, workers will grab them tightly. At this time, workers' hands can easily be pulled between the shackle and the guy ropes, posing a risk of their hands being squeezed or pinched.

[0005] Therefore, it is necessary to provide a controllable locking device for guy ropes used in wind turbine hoisting to solve the above problems. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a controllable locking device for guy ropes used in wind turbine hoisting, so as to protect the workers.

[0007] The technical solution adopted by this application to solve its technical problem is: a controllable locking device for guy ropes used in wind turbine hoisting, comprising: Main arm; At least one rope-winding post is fixed to one side of the front end of the main arm; A rope threading hole is located on the side of the rope winding post near the end of the main arm; An auxiliary arm, the front end of which is rotatably connected to the main arm; A rope-locking post is fixed to one side of the front end of the auxiliary arm, and the rope-locking post is positioned corresponding to the rope-winding post.

[0008] Furthermore, both the main arm and the auxiliary arm have C-shaped cross-sections, and the opening directions of their cross-sections are opposite.

[0009] Furthermore, a notch is provided between the rope hole and the main arm.

[0010] Furthermore, a fixing hole is provided at the front end of the main arm.

[0011] Furthermore, a friction sleeve is fitted onto the rope-locking post.

[0012] Furthermore, a platform is provided on one side of the locking rope post, and the inner ring of the friction sleeve is adapted to the locking rope post.

[0013] Furthermore, a support plate is fixedly installed on one side of the end of the main arm, and a pawl is rotatably connected between one end of the support plate and the main arm. An elastic element is connected between the pawl and the support plate. A stop bar is provided between the other end of the support plate and the main arm. A movable rod is rotatably provided on one side of the end of the auxiliary arm. One end of the movable rod is inserted between the pawl and the stop bar. Several ratchet teeth are provided on the side of the movable rod near the pawl.

[0014] Furthermore, the support plate is provided with a clearance groove corresponding to the position of the stop bar. One side of the clearance groove extends to the edge of the support plate, and a fixing rod is fixed on both sides of the clearance groove. One end of the stop bar is rotatably connected to the main arm, and the other end of the stop bar passes through the clearance groove and is rotatably connected to a limit rod.

[0015] Furthermore, a buckle is provided on one side of the main arm.

[0016] The beneficial effects of this invention are: During the preparation stage, after one end of the guy rope is fixed to the hoisting load, the subsequent guy ropes are inserted between the main boom and the auxiliary boom, and then passed through the rope hole. Afterwards, they are wound around each rope winding post 1-2 times to complete the rope laying. When in use, the weight of the hoisting load itself will pull the guy ropes out sequentially along the rope winding post, rope hole and rope inlet. The winding of the guy rope on the rope post provides the basic friction for the guy rope, ensuring that the guy rope is released smoothly and slowly. By controlling the opening and closing of the main boom and auxiliary boom, the staff can clamp or loosen the guy rope by the rope winding post and the rope locking post, thereby changing the resistance of the guy rope caused by the clamping force between the rope winding post and the rope locking post, and thus adjusting the speed at which the guy rope is pulled out. This control method prevents the guy rope from coming into contact with the user's hands, avoiding the risk of hand chafing or being pinched. It also allows one person to operate the rope, achieving the effects of preventing entanglement, protecting personnel safety, and reducing manpower input. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0021] like Figure 1-7 As shown, this application provides a controllable locking device for guy ropes used in wind turbine hoisting, including a main boom 1 and an auxiliary boom 2, with the front ends of the main boom 1 and the auxiliary boom 2 rotatably connected.

[0022] At least one rope-winding post is provided on the main arm 1. In this embodiment, taking the first rope-winding post 11 and the second rope-winding post 12 fixed on both sides of the front end of the main arm 1 as an example, a rope-passing hole 13 is also provided on one side of the front end of the main arm 1, and the rope-passing hole 13 is located on the side of the first rope-winding post 11 near the end of the main arm 1.

[0023] A rope-locking post 21 is provided on one side of the front end of the auxiliary arm 2.

[0024] Both the main arm 1 and the auxiliary arm 2 have C-shaped cross sections, and the opening directions of the cross sections of the main arm 1 and the auxiliary arm 2 are opposite, forming a cavity between the main arm 1 and the auxiliary arm 2. The end of this cavity near the end of the main arm 1 is set as the rope entry point.

[0025] During the preparation stage, after one end of the guy rope is fixed to the hoisting load, the subsequent guy rope is inserted between the main boom 1 and the auxiliary boom 2 through the rope inlet, and then passed out through the rope hole 13. Subsequently, it is wound around the first rope winding post 11 and the second rope winding post 12 1-2 times respectively (taking 1 turn as an example in the figure) to complete the rope laying.

[0026] When in use, the weight of the hoisting object itself will pull the guy ropes sequentially along the second rope winding post 12, the first rope winding post 11, the rope threading hole 13 and the rope threading inlet.

[0027] By winding the guy rope around the first winding post 11 and the second winding post 12, the first winding post 11 and the second winding post 12 provide the guy rope with basic friction, ensuring that the guy rope is pulled out smoothly and gradually. By increasing or decreasing the number of turns of the guy rope around the first winding post 11 and the second winding post 12, the basic friction force on the guy rope can be adjusted, thereby roughly adjusting the speed at which the guy rope is pulled out.

[0028] A notch is provided between the rope hole 13 and the main boom 1, which allows the user to directly insert the guy rope from the side between the main boom 1 and the auxiliary boom 2 and into the rope hole 13 after the main boom 1 and the auxiliary boom 2 are opened to a large extent, thus achieving the effect of convenient operation.

[0029] After the user holds the main arm 1 and the auxiliary arm 2 with one hand, by opening and closing the hand, the user can press and release the main arm 1 and the auxiliary arm 2, thereby causing the second rope winding post 12 and the rope locking post 21 to clamp or release the guy rope. This changes the clamping force between the second rope winding post 12 and the rope locking post 21 on the guy rope, thereby changing the resistance caused by the clamping force on the guy rope, and thus adjusting the speed at which the guy rope is pulled out, achieving the effect of fine-tuning the speed at which the guy rope is pulled out. At the same time, the guy rope will not come into contact with the user's hand, which can avoid the risk of hand chafing or hand being pinched.

[0030] By gripping the main arm 1 and the auxiliary arm 2, the second rope winding post 12 and the rope locking post 21 can clamp the guy rope, preventing it from being pulled out further, thus achieving the effect of locking the guy rope.

[0031] The front end of the main boom 1 is provided with a fixing hole 14. The fixing hole 14 is used to connect with a ground anchor or other fixing object to the shackle, so that the position of the controllable locking device for the guy rope used for wind turbine hoisting is fixed, and it is prevented from being pulled away by the guy rope.

[0032] This operating method allows a single worker to control the speed at which the guy rope is pulled out, while avoiding direct contact between the worker's hands and the guy rope, thus preventing entanglement, protecting personnel safety, and reducing manpower input.

[0033] A friction sleeve 22 is fitted onto the locking post 21. The locking post 21 passes through the friction sleeve 22 and, in conjunction with the second winding post 12, clamps the guy rope. The friction sleeve 22 increases the overall diameter of the locking post 21, preventing situations where the guy rope is too thin and the locking post 21 and the second winding post 12 cannot clamp it properly. This allows the controllable locking device for guy ropes used in wind turbine hoisting to be adaptable to guy ropes of different thicknesses.

[0034] A platform 23 is provided on one side of the rope locking post 21, and the inner ring of the friction sleeve 22 is adapted to the rope locking post 21. The platform 23 can prevent the friction sleeve 22 from rotating around the rope locking post 21, thereby stabilizing the resistance of the guy rope caused by the clamping force between the second rope winding post 12 and the friction sleeve 22.

[0035] A support plate 3 is fixedly installed on one side of the end of the main boom 1. A pawl 31 is rotatably connected between one end of the support plate 3 and the main boom 1. An elastic element 32 is connected between the pawl 31 and the support plate 3. In this embodiment, the elastic element 32 is a spring. A stop bar 33 is provided between the other end of the support plate 3 and the main boom 1.

[0036] A movable rod 34 is rotatably mounted on one side of the end of the auxiliary arm 2. One end of the movable rod 34 is inserted between the pawl 31 and the stop bar 33. Several ratchet teeth 35 are provided on the side of the movable rod 34 near the pawl 31. This structure forms a ratchet mechanism, ensuring that after the movable rod 34 is inserted between the pawl 31 and the stop bar 33, the main arm 1 and the auxiliary arm 2 can only be closed and cannot be opened. This allows workers to maintain the pull-out speed of the guy rope without having to hold the main arm 1 and the auxiliary arm 2 after adjusting the clamping resistance of the locking post 21 and the second winding post 12 on the guy rope, thus achieving a labor-saving effect.

[0037] The support plate 3 is provided with a clearance groove 36 corresponding to the position of the stop bar 33, and one side of the clearance groove 36 extends to the edge of the support plate 3. One end of the stop bar 33 is rotatably connected to the main arm 1, and the other end of the stop bar 33 passes through the clearance groove 36 and is rotatably connected to the limit rod 37. Fixing rods 38 are fixed on both sides of the clearance groove 36.

[0038] After one end of the stop bar 33 passes through the clearance groove 36, by rotating the limiting rod 37 so that the length direction of the limiting rod 37 and the stop bar 33 are perpendicular, the fixing rod 38 will block the stop bar 33 through the limiting rod 37, so that the stop bar 33 can restrict the position of the movable rod 34, thereby keeping the ratchet 35 engaged with the pawl 31.

[0039] By rotating the limiting rod 37 so that its length direction is collinear with that of the stop rod 33, the limiting rod 37 will not be blocked by the fixed rod 38. The stop rod 33 can then be rotated and engaged or disengaged from the clearance groove 36. After the stop rod 33 disengages from the clearance groove 36, the movable rod 34 can freely enter or leave the ratchet mechanism, disabling or assembling it, thus facilitating its disassembly and assembly. This allows the user to adjust the opening and closing of the ratchet mechanism according to usage, enabling them to close it at any time to adjust the guy rope extraction speed in real time; or, when it is necessary to maintain the guy rope extraction speed, the ratchet mechanism can be directly engaged to help the user maintain the opening angle between the main arm 1 and the auxiliary arm 2, saving the user effort.

[0040] The limiting rod 37 is magnetic, and the fixing rod 38 is made of magnetic metal. The magnetic force between the limiting rod 37 and the fixing rod 38 facilitates fixation.

[0041] A buckle 4 is installed on one side of the main boom 1. When it is necessary to lock the guy rope for a long time, after the second rope winding post 12 and the rope locking post 21 clamp the guy rope, the end of the guy rope extending between the second rope winding post 12 and the rope locking post 21 is wrapped around the main boom 1 and the auxiliary boom 2 several times, and then the buckle 4 is used to fix this end of the guy rope. At this time, even if the guy rope is pulled by the hoisted load, the pulled guy rope will wrap more tightly between the main boom 1 and the auxiliary boom 2, increasing the clamping force between the second rope winding post 12 and the rope locking post 21 on the guy rope, preventing the guy rope from being pulled further, so as to achieve the effect of locking the guy rope for a long time. The buckle 4 is used to prevent the guy rope wrapped around the main boom 1 and the auxiliary boom 2 from accidentally coming loose, ensuring hoisting safety.
