2. A special device for putting in and out of a locking beam is designed, and the locking beam is lifted and put in by using a bracket and a chain block. Through research, the danger of operation and maintenance personnel when carrying the locking beam can be reduced in the mode, but the loss of mechanical transmission parts is large, regular maintenance is needed, and personnel operation is still needed, so that the waste of manpower resources and transportation force is caused.
3. An automatic device for locking the beam to be thrown or withdrawn is designed, and the automatic throwing or withdrawing of the locking is realized through mechanical hydraulic transmission. Through feasibility research, the scheme eliminates the safety risk of manually throwing and withdrawing the locking beam, saves human resources and transportation resources, realizes remote automatic throwing and withdrawing of the locking beam, and can be researched.
In summary, in order to solve the automatic switching problem of the locking beam of the access gate, the following solutions are proposed.
