The invention discloses a cable bridge of facilitating fast erection. The cable bridge comprises a wiring duct, suspension brackets and T-shaped plane chutes, wherein the suspension brackets are arranged at the outer sides of two side walls of the wiring duct; horizontal sections are arranged at two ends of each suspension bracket and a vertical section is arranged in the middle; a plurality of suspension brackets are arranged along the wiring duct; the other ends of the horizontal sections of the suspension brackets are welded on the corresponding side walls of the wiring duct; the T-shaped plane chutes are arranged along the wiring duct and are fastened to the vertical sections of the corresponding suspension brackets through clamping hoops; the clamping hoops are welded on the backs ofthe corresponding T-shaped plane chutes; and a plurality of L-shaped sliding blocks capable of being matched with the corresponding T-shaped plane chutes in a sliding manner are arranged in the T-shaped plane chutes. Through coordination of the suspension brackets and the T-shaped plane chutes and coordination of the T-shaped plane chutes and the L-shaped sliding blocks, the hoisting height and width can be adjusted when the cable bridge is hoisted, and the hoisting balance and stability of the cable bridge can be ensured, so that convenient and reliable hoisting of the cable bridge is achieved.

An electronic control dual-drive hydrogen storage valve comprises a valve body, hand wheels, a first support rod, a second support rod, a cylindrical connector, pawls, a third support rod, a spiral groove, an armature, electromagnetic coils, a piston, outlets, fan rib channels, one-way valves, a storage portion, a fan-shaped sealing portion, a cross groove, a vertical groove and an electronic drive module. A dual-drive module, a dual-on-off module and a butt joint module are arranged in the valve. The cross groove and the vertical groove are formed in the valve body. The circumferential distance between the two grooves is equal to one fourth of the outer circumference of the valve body. The electronic drive module comprises a capacitor, a resistor, a relay, contacts Al and A2 and a power source. One end of the power source is connected with the electromagnetic coils of the hydrogen storage valve, and the other end of the power source is connected with an on-off circuit. In the on-off circuit, the contacts A1 and A2 are connected or disconnected so that the circuit is closed or opened. The relay is connected with the capacitor in parallel. The resistor is connected with the relay inseries.

The invention discloses a wind turbine blade overturning vehicle. The wind turbine blade overturning vehicle comprises a vehicle frame and an overturning device mounted on the vehicle frame; the overturning device comprises a rolling ring, and further comprises a first clamp and a second clamp which are mounted on the rolling ring and face oppositely; a clamping area for wind turbine blades is formed between the first clamp and the second clamp; the first clamp is connected with the rolling ring through two position adjusting mechanisms, and a position adjusting guiding mechanism is arranged between the two position adjusting mechanisms; the position adjusting guiding mechanism comprises a guiding groove formed in the first clamp and an adjusting bearing mounted in the guiding groove; andthe guiding groove and the position adjusting mechanisms are consistent in direction, the outer diameter of the adjusting bearing is consistent with the width of the guiding groove, and the adjustingbearing is fixedly mounted on the rolling ring through bolts. The wind turbine blade overturning vehicle is simple in structure, safe and reliable, it can be ensured that the molded surfaces of the blades are better attached to the clamps and the shape following property is good, and scraping damage of the clamps to the blades in the machining process is reduced.
