Safe supporting device of hydraulic lifting gate
The invention discloses a safe supporting device of a hydraulic lifting gate. The safe supporting device is provided with a dam body, a bottom shaft support, a limiting block, a piston cylinder and a supporting block; a bottom shaft is fixedly arranged at the lower end of the dam body; the bottom shaft is rotatably installed on the bottom shaft support; the limiting block is fixed to the bottom shaft; a notch is formed in the limiting block; the supporting block is installed on a piston rod of the piston cylinder; the supporting block can be driven by the piston cylinder to stretch into or stretch out of the notch in the limiting block; when the dam body is vertical, the supporting block can stretch into the notch in the limiting block through the position of the notch, and the rotation of the dam body is locked. The supporting block is not stressed in a conventional state, when the gate is lifted to the highest position, the piston cylinder is started, the supporting block is pushed to stretch into the notch of the limiting block, and the gate is prevented from being opened accidentally on account of pressure relief of a main oil cylinder.
