Problems solved by technology
However, when the above-mentioned electromagnetic suspension girder bridge crane transports steel slabs, in addition to the crane driver, a special person must be set up on the ground to direct its handling operations. The magnetic system can keep the electromagnetic chuck working for a short time until it completes the working cycle; however, in the event of accidents such as improper hoisting methods, vibrations, etc. causing overload, it will also cause the steel slab to fall off, causing damage to the roller table or casualties, etc. safety accidents and cause significant economic losses to the enterprise

The invention relates to a hydraulic protection device for steel sheet billet handling and an operation method thereof. The hydraulic protection device is characterized in that four synchronously moving hydraulic oil cylinder sets which are driven by a hydraulic system are installed on the top surface of a suspended beam of the hydraulic protection device, each hydraulic oil cylinder set consists of a lifting oil cylinder and a rotating oil cylinder, protection claws are connected onto the output shafts of the rotating oil cylinders corresponding to the position of a steel sheet billet which is on the bottom surface of an electromagnetic disc and is handled, and a limiting switch is installed on the external side surface of the bottom of a sliding column of the hydraulic protection device; and the hydraulic system consists of a lifting oil cylinder, a first one-way throttling valve, a three-position three-way electromagnetic overflow valve, a hydraulic pump, a rotating oil cylinder, a second one-way throttling valve, a three-position four-way electromagnetic overflow valve, an energy accumulator, a pressure gauge, an air filter, a venting atmospheric oil tank and connecting pipelines among the hydraulic components. The invention has the advantages that the device can run stably, the steel sheet billet can be handled smoothly, the labor is saved, the device is very convenient to operate and use and the other advantages.
Description
technical field [0001] The invention belongs to bridge crane equipment, and in particular relates to a steel slab handling hydraulic protection device and an operating method thereof, which are suitable for electromagnetic hanging beam bridge cranes to carry steel slabs. Background technique [0002] At present, steel slab handling cranes such as electromagnetic hanging beam bridge cranes are equipped with a power-off magnetic protection system. The two ends of the hanging beam are symmetrically connected to the middle of the two ∏-shaped horizontal plates, and the hooking pieces of the lifting device hook are symmetrically arranged on the two cover plates in the center of the hanging beam. An electromagnet connecting device and an electromagnet connected to the electromagnet connecting device are installed at the center of the bottom surface of the horizontal horizontal plate, and a buffer is installed at both ends of the bottom surface of each ∏-shaped horizontal plate; th...
