DETAILED DESCRIPTION

[0022] The utility model makes further detailed description in combination with drawings.

[0023] To solve the above technical problem, the utility model provides a technical scheme for a wind power facility hoisting piece, which is combined with Figures 1-3 It comprises: a telescopic rod is arranged below the boom 1, support rods 3 are rotatably connected to the two ends of the boom 1 and the telescopic rod, the boom 1, the telescopic rod and the support rods 3 jointly form a main body structure of the hoisting piece in the shape of an upright trapezoid, and wind power component parts are hoisted below the two ends of the telescopic rod through hoisting ropes;

[0024] A plurality of lifting rings 2 are arranged on the two sides of the boom 1, and the crane sequentially penetrates the two lifting rings 2 at the end of the boom 1 through hoisting ropes to lift the hoisting piece;

[0025] A plurality of lifting holes 10 are arranged below the screw cylinder 8, and the hoisting ropes lift the wind power component parts by being hung in any lifting hole 10;

[0026] The hoisting piece provided in the application is used to form a bridge between the hoisting ropes of the crane and the wind power facility component parts, so when the device is used, the hoisting ropes are divided into two parts, one part is wound on the lifting ring 2 of the boom 1 through the bottom end, and the device is lifted by the crane, and the other part is wound in the lifting hole 10 below the screw cylinder 8 through the top end, and the wind power component parts are lifted;

[0027] Combined with Figures 1-4 In the technical scheme, two groups of four lifting rings 2 are arranged, each group is arranged at the two ends of the boom 1, and the two lifting rings 2 in each group are arranged on the two sides of the boom 1, so that the part of the hoisting rope of the crane that contacts and hangs the boom 1 is expanded from one point to two points or one section, and the contact and bearing area is increased, which can effectively relieve the bearing pressure of the bottom end of the hoisting rope and provide a certain protection effect, and a plurality of lifting holes 10 are arranged below the screw cylinder 8, which increases the selectivity when the wind power component parts are hoisted, and the hole positions below the two screw sleeves are symmetrically arranged;

[0028] Combined with Figures 1-3 and Figure 5 The telescopic rod comprises a transmission shaft 5, a bidirectional output motor 4 that is in transmission cooperation with the transmission shaft 5 is arranged below the boom 1, a mounting frame 11 for mounting the motor 4 is slidably connected below the boom 1, a plurality of sliding holes 13 are arranged on the boom 1, the mounting frame 11 is upwardly connected with a sliding rod 12 that is slidably connected with the boom 1 by penetrating the sliding holes 13, and a limiting piece 14 is connected to the top end of the sliding rod 12;

[0029] The end of the transmission shaft 5 is provided with a screw rod 7, the outer thread structure of the screw rod 7 is opposite to each other and is threadedly connected with a screw cylinder 8, the end of the screw cylinder 8 is upwardly connected with a support block 9, and the bottom end of the support rod 3 is rotatably connected to the support block 9;

[0030] Since the wind power components are generally relatively long, the part of the hoisting rope hooked by the hoisting rope is almost close to the point of contact in the macroscopic view. By adjusting the assembly, the two hoisting parts are expanded outward, and the two hoisting ropes are hung on the two ends of the long wind power component as much as possible, so as to enhance the stability of the wind power component when it is hung in the air.

[0031] The motor 4 drives the transmission shaft 5 and the screw rod 7 to rotate. Since the screw cylinder 8 is installed on the hoisting rod 1 through the support rod 3, there is a certain limiting condition. Therefore, the screw cylinder 8 moves at both ends below the hoisting rod 1 under the rotation of the screw rod 7. When the two screw cylinders 8 are close to or away from each other, the inclination of the support rod 3 also changes, including the lifting of the hoisting rod 1 or the partial lowering of the screw rod 7, which does not affect the use of the overall trapezoidal frame hoisting piece. Since the part where the motor 4 is installed moves relative to the hoisting rod 1, the mounting frame 11 that bears the motor 4 is connected to the hoisting rod 1 through the sliding rod 12.

[0032] In combination with the accompanying drawings Figure 5 A damper 6 is installed between the ends of the transmission shaft 5 and the screw rod 7. A plurality of support plates with sliding grooves 16 are connected to the edge of the end of the transmission shaft 5. A plurality of sliding plates 15 are connected to the edge of the end of the screw rod 7 and are in close contact with the inner wall of the support plate. The end of the sliding plate 15 outwardly penetrates the sliding groove 16 and is slidably connected to the support plate through the clamping piece 17. The sliding plate 15 and the support plate are uniformly distributed around the damper 6.

[0033] After the screw sleeve hoists the heavy wind power component, the wind power component will sway in the air, which will generate horizontal transmission pressure. In order to protect the above-mentioned equipment and structure, a damper 6 is installed between the transmission shaft 5 and the screw rod 7, which can protect the motor 4 and other components from shock and buffer stress.

[0034] Further, since the shaft parts at both ends of the damper 6 are in a rotating state, a set of telescopic sliding plate structure is arranged between the two shafts. The sliding plate 15 at the end of the screw rod 7 is embedded into the sliding groove 16 on the transmission shaft 5, which does not hinder the damper 6 from working. They are jointly clamped by the clamping piece, and the damper 6 will not be affected in the rotation between them when the two end shafts rotate.

[0035] The utility model discloses a wind power part lifting device, which comprises a lifting rope, a motor, a transmission shaft, a screw rod, a screw cylinder and a plurality of lifting holes.

[0036] The above description of the utility model and its implementation mode is not restrictive, and the embodiment shown in the drawings is only one of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the utility model, without creative design, similar structure and embodiments of the technical scheme, which should belong to the protection scope of the utility model.
