Description

Technical Field

[0001] The invention relates to the technical field of construction hoisting, and in particular to a hoisting auxiliary device for wind power construction. Background Art

[0002] Since there are no obstacles in the ocean wind, the energy loss is small during the flow process, so the energy efficiency utilization rate of offshore wind power is higher than that of land. The structure of offshore wind power is similar to that of land wind power, mainly consisting of support parts, transmission parts, fan blades and generators. The support parts are composed of three conical hollow cylinders. The closing of the hollow cylinder will become smaller as it goes up. The adjacent hollow cylinders are fixed with raised flanges and bolts and nuts. Due to the relative height of wind power facilities, a lifting device is required to assist in the installation of the hollow cylinder.

[0003] The patent with announcement number CN117755952B discloses a lifting auxiliary device for offshore wind power construction, including a crane and a lifting device connected to the crane through a main lifting rope, the lifting device is used to fix the hollow cylinder, the lifting device includes a lifting rod and a plurality of supporting lifting ropes, the plurality of supporting lifting ropes are arranged in an equi-angle circular array, the lifting rod is connected to a transition ring through a plurality of supporting lifting ropes, the bottom of the transition ring is rotatably connected to an internally threaded cylinder, and the internally threaded cylinder matches the screw on the outer flange of the hollow cylinder.

[0004] However, the above-mentioned lifting auxiliary device for offshore wind power construction still has some shortcomings in actual use: 1. The angle alignment between the screw rod and the internal threaded barrel is too complicated, and it is impossible to ensure that only one threaded rod is engaged at the maximum opening of the arc-shaped guide rod; 2. The U-shaped frame is rotated by the support rope 2 to tighten the threaded barrel. The whole device is extremely unstable and it is easy to cause the support rope 2 to get knotted and entangled; 3. The support is generally composed of three conical hollow barrels. However, the diameter of the closing part of the three hollow barrels becomes smaller as they go up. The above-mentioned device cannot be applied to hollow barrels of different diameters. Therefore, a lifting auxiliary device for wind power construction is proposed to solve the above-mentioned problems. Summary of the invention

[0021] Compared with the existing technology, the advantages of this wind power construction hoisting auxiliary device are:

[0022] 1. When the positioning wheel contacts the inner wall of the hollow cylinder, the slide seat will be retracted into the support by pressure. First, the third gear will mesh with the fourth rack, so that the third gear drives the auxiliary bevel gear to rotate through the pulley assembly, and the auxiliary bevel gear drives another auxiliary bevel gear to rotate through the main bevel gear. The rotation directions of the two auxiliary bevel gears are opposite, so that the first connecting rod and the second connecting rod are opened outward, and the distance between the two positioning claws is set to be greater than the distance between the two threaded columns, ensuring that there is only one threaded column between the two positioning claws;

[0023] 2. When the two positioning claws are opened, if the threaded column is not in the middle of the two positioning claws, one of the positioning claws will conflict with an adjacent threaded column, so that the positioning wheel rolls on the inner wall of the hollow cylinder, thereby adjusting the position of the threaded cylinder. When the two positioning claws are fully opened, the traction rope will be pulled so that the third rack drives the first gear to rotate, and the first gear drives the second rack to move downward, so that the two second racks conflict with the flip plate together, thereby pressing the installation cylinder down so that the threaded cylinder is covered above the threaded rod;

[0024] 3. The purpose of setting the flip plate is that if only one of the second racks is squeezed, it proves that the two positioning claws have not moved to the correct position. Therefore, the flip plate will tilt at this time, so that the installation cylinder 1 will not be pressed down, ensuring the accuracy of the connection between the threaded cylinder and the threaded rod;

[0025] In summary, the present invention is suitable for the diameters of three hollow cylinders by setting a size adjustment mechanism. The positioning mechanism cooperates with the docking mechanism so that the installation cylinder is lowered only when the threaded cylinder is directly above the threaded column, thereby ensuring the accuracy of the docking between the threaded cylinder and the threaded rod. At the same time, after the lifting is completed, the device only needs to be reset to automatically disengage from the hollow cylinder without manual disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] When the two positioning claws 7 are opened, if the threaded column is not in the middle of the two positioning claws 7, one of the positioning claws 7 will conflict with an adjacent threaded column, so that the positioning wheel 25 rolls on the inner wall of the hollow cylinder, thereby adjusting the position of the threaded cylinder 6. When the two positioning claws 7 are fully opened, the traction rope 19 will be pulled so that the third rack 20 drives the first gear 21 to rotate, and the first gear 21 drives the second rack 13 to move downward, so that the two second racks 13 conflict with the flip plate 28 together, thereby pressing the installation cylinder 1 29 downward so that the threaded cylinder 6 covers the threaded rod, and the flip plate 28 is provided so that if only one second rack 13 is squeezed, it proves that the two positioning claws 7 have not moved to the correct position, so at this time the flip plate 28 will be tilted, so that the installation cylinder 1 29 will not be pressed down, thereby ensuring the accuracy of the connection between the threaded cylinder 6 and the threaded rod.

[0055] When the slide 5 continues to extend, the blocking block 39 will drive the fixing rod 2 40 to move, so that the first rack 9 will push the fifth gear 47 to rotate, so that the fourth gear 46 drives the gear ring 10 to rotate, thereby screwing the threaded tube 6 into the outer wall of the threaded column to complete the connection. At the same time, when the lifting is completed, the device only needs to be reset to automatically disengage from the hollow tube.
