Description

Technical Field

[0001] The utility model relates to the technical field of marine cargo transportation, in particular to a bridge-shaped connector. Background Art

[0002] Wind power is a green, environmentally friendly, renewable new energy. In wind power generation, blades are an important part of wind energy utilization and directly affect the conversion efficiency of wind energy. With the increasing environmental awareness of various countries, the demand for the development and utilization of new energy such as wind power is also increasing. Wind turbine blades are also getting bigger and bigger, ranging from tens of meters to hundreds of meters in length. In addition to the advanced and complex processes required for production, the storage, transportation, lifting and installation of blades have also become a big problem.

[0003] When transporting by sea, the blades need to be placed on the ship using a frame and then transported.

[0004] At present, the blades are fixed on the frame, and the frame is placed on the ship. Since the frame is placed on the ship by hoisting, each frame is relatively independent and the positions of the frames are inconsistent, and they do not form a whole. When the ship is shaken by external force, each frame is independently fixed and unstable, and is prone to shaking, translation or tipping. At the same time, each frame needs to be fastened with multiple lashing parts, and the assembly and disassembly work needs to be carried out many times during assembly and disassembly, which has high labor intensity and slow loading and unloading efficiency. In addition, some frames are stacked up and down, and workers are required to perform high-altitude operations when the lashing parts are fixed. The longer the high-altitude operation time, the greater the safety risk. Utility Model Content

[0066] When the force arm 54 is fixed by inserting the R-shaped pin 53 into the clamping hole 521:

[0067] The locking rod 531 is first inserted into the locking hole 521 and pushed backward. At this time, the inclined rod 534 is in contact with the limit screw 52, ​​and pressure is continuously applied to the locking rod 531. The friction between the limit screw 52 and the inclined rod 534 will cause the connecting end of the inclined rod 534 and the arc-shaped rod 533 to tilt upward, so that the top of the limit screw 52 is stuck in the inner cavity of the arc-shaped rod 533, and the R-shaped pin 53 is installed. When disassembling the R-shaped pin 53, hold the elastic ring part 532 and drag it backward.
