In order to achieve the above purpose, the technical solution adopted is: a wind power blade web hoisting tool, which is characterized in that it consists of an upper integral lifting beam (1) and a lower lifting tool (8), and the integral lifting beam (1) consists of A plurality of supporting beams (3) are connected by flanges (2). The overall hanging beam (1) is symmetrically provided with suspenders (6) on both sides. The top of the suspenders (6) is provided with upper lugs (7). (7) The two sides are connected to the overall hanging beam (1) through the steel wire rope (5) to ensure the lifting balance; the bottom of the integral hanging beam (1) is symmetrically provided with hooks (9) on both sides, and the hooks (9) and the lifting gear ( 8) Connection, the web (10) is placed in the spreader (8).

The distance between the suspension rod (6) and the end of the integral suspension beam (1) is one-third of the length of the integral suspension beam (1).

The spreader (8) is as follows: the lead screw (84) is fixed in the middle of the beam of the spreader (8) through the hand wheel (83), the upper two sides of the beam are provided with lower lugs (82), and the lower two are provided with Positioning bar (81), leading screw (84) bottom is provided with suspender (85), and web (9) is placed on the suspender (85).

The overall hanging beam (1) is manufactured by welding, and the weld seam position is reinforced by welding of steel plates (4).

The beneficial effects of the utility model are: the whole hanging beam is connected in sections, and the manufacture, transportation and use are convenient. It is easy to operate, safe and reliable by lifting and clamping the tooling by collecting the web, and cooperating with the integral lifting beam of the web. It solves the problems of twisting and deformation caused by segmented lifting beams during web hoisting or web shaking and deformation caused by ratchet belt binding and hoisting.

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

Embodiment 1: As shown in Figure 1-2, a wind power blade web hoisting tool is composed of an upper integral lifting beam 1 and a lower lifting tool 8, and the integral lifting beam 1 is composed of multiple supporting beams 3 passing through the flange 2 connection composition, the two sides of the overall suspension beam 1 are symmetrically provided with suspension rods 6, and the top of the suspension rod 6 is provided with upper lifting lugs 7, and the two sides of the upper lifting lugs 7 are connected with the overall suspension beam 1 through steel wire ropes 5 to ensure the lifting balance; the overall suspension beam 1 Bottom two sides are symmetrically provided with suspension hook 9, and suspension hook 9 is connected with hanger 8. The distance between suspension rod 6 and the end of integral suspension beam 1 is 1/3rd of the length of integral suspension beam 1 .

The spreader 8 is as follows: a lead screw 84 is fixed in the middle of the crossbeam of the spreader 8 through a hand wheel 83, the upper two sides of the crossbeam are provided with lower lugs 82, the lower two are provided with positioning rods 81, and the bottom of the lead screw 84 is provided with There is a hanger 85 on which the web 10 is placed.

The length of the supporting and hanging beams 3 is 6 meters, and the supporting and hanging beams 3 are fixedly connected by flanges.

I adjust the length freely as needed. Square tube structural welding is adopted, and the structural performance is stable. The weld position is reinforced by steel plate 4 welding.

Hoisting process: first install the spreader 8 on the web 10, the positioning rod 81 fixes the web 10, rotate the handwheel 83 to drive the screw 84 to clamp the hanger 85 and the web 10, and the overall hanging beam 1 passes the upper lug 7. Hoist with a crane, open to the hoisting position, connect the suspension hook 9 with the lower lug 82, and hoist as a whole.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
