Bent frame column horizontal beam anti-colliding protecting system

The invention discloses a bent frame column horizontal beam anti-colliding protecting system which comprises a plurality of arc gates arranged on a gate pier at intervals. Arc gate supports are arranged on the two sides of the back portion of each arch valve. The back ends of the arc gate supports are hinged to arc gate supporting hinge bases. The two ends of the back portion of each arc gate are hinged to piston rods of a hydraulic oil cylinder respectively. A plurality of bent frame columns are arranged above the gate pier. Bent frame column horizontal beam horizontal beams are arranged between the bent frame columns horizontally. A left limiting end rod and a right limiting end rod are arranged on the two sides of the top of each arc gate respectively. Left travel switches and right travel switches are arranged on the bent frame column horizontal beams placed above the left limiting end rods and the right limiting end rods. The left limiting end rods and the right limiting end rods are connected with the arc gates through adjusting bolts. The left travel switches and the right travel switches are connected in series into a circuit of an oil cylinder oil supply solenoid valve coil. The bent frame column horizontal beam anti-colliding protecting system has the advantages that the safety of a hydraulic structure can be guaranteed at an equipment fault state, the damaging risks of the hydraulic structure are reduced, and the maximum social benefit of engineering construction is achieved.
