The invention discloses a horizontal hoisting sling for a single fan blade, and relates to the technical field of fan blade installation. The horizontal hoisting sling comprises a main platform, clamping frames, rolling oil cylinders, a machine room, main hoisting belts, blade bottom-supporting hoisting belts and hinge shafts, wherein the two clamping frames are arranged at the two ends of the main platform, each clamping frame is connected with the main platform through one hinge shaft, the upper end of each clamping frame is provided with a rolling oil cylinder, the rolling oil cylinders are connected with the clamping frames and the main platform, the rolling oil cylinders can drive the clamping frames to rotate around the hinge shafts, the lower end of each clamping frame is provided with one blade bottom-supporting hoisting belt, the machine room is arranged on the upper side of the main platform, and a plurality of main hoisting belts are arranged at the upper end of the main platform. The hoisting sling is large in variable pitch range, and can be used for hoisting the blades in various postures; the hoisting sling can be quickly separated from the blade, so that the risk that the blade is collided and damaged is reduced; and the system integration degree is high, and all power and control systems are arranged in the machine room in a centralized mode, so that testing, checking and maintaining are facilitated.
Description
technical field [0001] The invention relates to the technical field of fan blade installation, in particular to a horizontal hoisting sling for a fan single blade. Background technique [0002] As the blades become more and more large, due to site constraints, the traditional construction method of assembling three blades and the hub on the ground and then hoisting them as a whole cannot be used. Each blade needs to be installed on the hub separately at high altitude. The shape of the blade is irregular, and the attitude of the blade is also at a certain angle during transportation. According to different construction conditions, the attitude of the blade varies between -4°~+17°. The existing single-blade spreader can only adjust the pitch within a small range, which cannot meet the needs. It is necessary to develop a spreader with a wide range of pitch functions to lift the blades. Contents of the invention [0003] The object of the present invention is to provide a si...
