Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade technology, and in particular relates to a single web plate hoisting fixture for wind turbine blades. Background Technology

[0002] The web, a crucial structural component of wind turbine blades, is assembled from two separate leading and trailing edge webs bonded together using connecting blocks. During assembly, lifting equipment is needed to hoist the individual webs onto the assembly fixture. Conventional hoisting methods include direct lifting with slings and hoisting with transport fixtures. Hoisting with slings can easily damage the web flanges; therefore, transport fixtures are commonly used. Existing transport fixtures typically consist of two sets of lifting components, each including bolts and clamping plates. The bolts at both ends drive the clamping plates, thus clamping the web for hoisting. However, due to the large thread stroke and the need to tighten the bolts at both ends, tightening the bolts during web clamping is time-consuming, resulting in low overall hoisting efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a single web lifting fixture for wind turbine blades to solve the problem of time-consuming operation of existing lifting fixtures.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a single web plate hoisting fixture for wind turbine blades, comprising several sets of hoisting units, which are arranged along the length of the web plate; each set of hoisting units includes a U-shaped bracket, a first clamping part, and a second clamping part, one side of the web plate being able to be inserted into the slot of the bracket; the first clamping part and the second clamping part are respectively located on both sides of the bracket; the first clamping part includes a support plate, a sleeve, an adjusting rod, and a stop pin, the bracket is provided with an installation hole, the sleeve is fixed in the installation hole, the sleeve has sliding grooves on both sides inside, and the sleeve is provided with... The sleeve has a groove that is offset from the sliding groove; the adjusting rod can move within the sleeve; the adjusting rod has a fixing hole, and the stop pin is fixed in the fixing hole, and the stop pin is perpendicular to the adjusting rod; both sides of the stop pin extend out of the fixing hole and are slidably connected to the sliding groove, and both sides of the stop pin can be located within the groove; the support plate is fixed to the end of the adjusting rod; the second clamping part includes a clamping plate and a threaded component, the bracket has a threaded hole that matches the threaded component, the threaded component is threadedly connected in the threaded hole, and the clamping plate is rotatably connected to one end of the threaded component; the clamping plate and the support plate are used to clamp both sides of the web plate.

[0005] Furthermore, both the support plate and the clamping plate are provided with rubber pads on the clamping side.

[0006] Furthermore, the support has a lifting lug on its back.

[0007] Furthermore, the adjusting rod is designed as a T-shaped structure, with the vertical end of the adjusting rod fixed to the support plate, and the fixing hole located on the vertical side of the adjusting rod.

[0008] Furthermore, the threaded component is provided with a handle.

[0009] The working principle of this technical solution is as follows:

[0010] After the web is fabricated, it is initially placed flat. The fixture is inserted into the web from the side. The adjusting rod is rotated to align the stop pin with the slide groove. The adjusting rod is then pushed to slide within the slide groove, moving the support plate until the stop pin is outside the slide groove. The adjusting rod is then rotated again to engage the stop pin in the groove. Next, the threaded component on the other side is rotated, causing it to move the clamping plate, ultimately securing the web between the clamping plate and the support plate. Once all lifting units are installed using the above method, the crane's lifting ring is connected to the lifting lug. The crane is then used to lift the fixture, allowing the web to be adjusted from a flat position to an upright position. Finally, the web can be lifted normally.

[0011] The beneficial effects of this technical solution are as follows:

[0012] In this technical solution, only one side uses a threaded connection, while the other side uses a sliding connection, and a stop pin is used for limiting. The efficiency of sliding is greater than that of threaded rotation. Therefore, this solution is more efficient than using threaded connections on both sides. Attached Figure Description

Each lifting unit includes a U-shaped bracket 1, a first clamping part 16, and a second clamping part 17. One side of the web 15 can be inserted into the slot of the bracket 1. The first clamping part 16 and the second clamping part 17 are respectively located on both sides of the bracket 1, and the back of the bracket 1 is provided with lifting lugs 2.

[0021] The first clamping part 16 includes a support plate 8, a sleeve 4, an adjusting rod 7, and a stop pin 13. The bracket 1 has mounting holes, and the sleeve 4 is fixed within the mounting holes. The sleeve 4 has two side grooves 5 inside, and two side grooves 6 are provided on both sides of the end of the sleeve 4 near the second clamping part 17. The grooves 6 and the side grooves 5 are staggered. In this embodiment, two sets of grooves 6 and two sets of side grooves 5 are evenly distributed around the circumference of the sleeve. The adjusting rod 7 has a T-shaped structure, and its vertical side can move within the sleeve 4. A fixing hole is provided on the vertical side of the adjusting rod 7, and the stop pin 13 is fixed within the fixing hole, perpendicular to the vertical side of the adjusting rod 7.
