A cable winding device for power construction, relating to the field of power construction equipment, includes a mobile platform, a cable winding device, and a jet-blowing dust collection device. The jet-blowing dust collection device is equipped with a rotatable jet-blowing component, with a cable channel at its center and radially distributed nozzles pointing towards the cable; a drive mechanism drives the jet-blowing component to rotate around the cable; fixed dust collection devices are symmetrically arranged on both sides of the jet-blowing component along its axial direction; an air supply system supplies air to the jet-blowing component and provides negative pressure to the dust collection devices through a negative pressure fan. By employing the synergistic effect of rotary jet-blowing and negative pressure dust collection, non-contact dynamic cleaning is achieved, completely solving the problems of cable scratches, secondary dust adsorption, and dust pollution caused by traditional brush cleaning.

This invention provides an automatic hook assembly / disassembly method, comprising the following steps: fixing hook body chucks and anti-rebound devices arranged vertically on a fixed bracket; hoisting the hook through the hook body chucks, with the lower cylinder of the hook confined within the hook body chucks and anti-rebound devices; moving the sleeve wrench to grip and clamp the upper cylinder of the hook; starting the sleeve wrench to rotate the upper cylinder of the hook, causing the upper cylinder to unfasten or fasten to the lower cylinder of the hook; removing the sleeve wrench and hoisting the hook away, completing the hook assembly / disassembly. Using this automatic hook assembly / disassembly method, the hook is effectively clamped, and the sleeve wrench, powered by a hydraulic station, rotates smoothly with adjustable speed and can rotate bidirectionally, simultaneously achieving hook disassembly and installation. The entire operation is stable and safe, eliminating the need for multiple operators to perform hammering, hoisting, or impact operations, completely eliminating multiple safety hazards and ensuring the safe conduct of hook repairs.

A titanium alloy consumable melting ingot cleaning equipment belongs to the technical field of surface grinding equipment in the process of titanium alloy material manufacturing, solves the problems of high labor intensity, low efficiency and unable to guarantee cleaning quality in the prior art, and comprises a base, two groups of parallel arranged spiral roller shafts rotatably arranged on the base, drive ends of the two groups of spiral roller shafts connected with a roller shaft transmission mechanism and a roller shaft drive motor, a closed cleaning box body arranged above the middle of the base and the spiral roller shafts, casting ingot passing ports respectively arranged on the front and back sides of the closed cleaning box body, a lifting platform arranged on the top of the closed cleaning box body, and a rust removal cleaning mechanism arranged on the lifting platform. The device is reasonable in design, compact in structure, capable of completely removing the impurities attached to the surface of the ingot, effectively improving the working environment, avoiding dust pollution to the environment, improving the working efficiency and guaranteeing the polishing quality of the titanium alloy ingot surface.

The invention provides test equipment for detecting the adhesive force of a water electrolysis hydrogen production electrode, and relates to the technical field of material test.The test equipment comprises a frame, a box is fixedly installed on the inner wall of the frame, an electrode body is arranged in the box, and a plurality of nozzles are arranged in the electrode body and located on one side of the electrode body; the hydraulic rod and the gear rack drive the clamping plate to synchronously clamp the electrode, so that the electrode is uniformly stressed and does not deviate; the rubber pads on the inner sides of the clamping plates can protect the electrode from being scratched and can also prevent displacement during impact, the clamping frame is stable, follow-up adjustment is facilitated, the first servo motor can drive the electrode to rotate, the angle and the speed are adjusted, high-pressure water flow flushes all the faces of the electrode, and one face is prevented from being detected. The water flow system can simulate the impact condition during real hydrogen production, so that the detection result is more effective, misjudgment is reduced, and waste and waste water pollution are reduced; the filter element can filter impurities, the second servo motor drives the brush to automatically clean the filter element, the bottom valve can directly discharge the impurities, and the overall detection efficiency is high.
