Double-lock-cylinder extruding hanging type mechanical grab beam device
The invention relates to a double-lock-cylinder extruding hanging type mechanical grab beam device provided with a grab beam body. The grab beam body is provided with handles. The handles are connected with half pulleys, guiding pulleys and lock cylinders through stay wires. The lock cylinders include the inner lock cylinder and the outer lock cylinder. The inner lock cylinder is embedded in a cavity of the outer lock cylinder, hooks are arranged at the lower ends of the lock cylinders and provided with hanging bodies, the hanging bodies are fixedly connected with a stop log, the half pulleys are connected and matched with control rods, and ejector rods are arranged at the top ends of the control rods. The double-lock-cylinder extruding hanging type mechanical grab beam device is easy and convenient to operate, safe in usage and small in occupied height space, the height of the hanging bodies is reduced, and the construction cost is reduced; meanwhile, the double-lock-cylinder extruding hanging type mechanical grab beam device is suitable for the stop log with the large operating space height, and is also particularly suitable for the stop log with the small operating space height, accidental unhooking events cannot happen in the lifting process of a grab beam, safety and reliability are achieved, the force of wrenching the handles is small, and operation and usage are easy and convenient.
