Problems solved by technology
However, when the hydraulic oil flows from the rod chamber to the rodless chamber, a vacuum will be formed in the rodless chamber, and the flipping of the pontoon springboard will be unstable or even stop. The only way to solve this problem is to turn on the power source and provide hydraulic pressure to the hydraulic system again. oil, so that the hydraulic control check valve in the hydraulic system is opened and the vacuum is added to ensure the smooth turning of the pontoon springboard, so the operation is more complicated, and it is difficult to accurately control the position of the critical point of the pontoon springboard

The invention discloses a hydraulic overturning device for a pontoon bridge gangplank. The hydraulic overturning device for the pontoon bridge gangplank comprises an oil tank, a hydraulic pump, a control valve set and an oil cylinder. The control valve set comprises a reversing valve, a duplex hydraulic control one-way valve and a stop valve. The hydraulic control one-way valve comprises a valve body. A valve element assembly is arranged in the valve body inner cavity and comprises a pair of opposite valve bases. Valve elements for controlling switch-on or switch-off of an oil way are arranged in the valve bases, a sliding rod capable of moving to open or close the valve elements in a jacking mode is arranged between the valve elements, and the length between the two ends of the sliding rod is 1.5 mm to 3 mm larger than the distance between the inner end faces of the valve elements. The hydraulic overturning device is compact in structure and stable and reliable to work, the length of the sliding rod in the hydraulic control one-way valve is slightly larger than the distance between the inner end faces of the valve elements, so that backflow and supplementing of hydraulic oil in the oil cylinder can be achieved, it is guaranteed that the oil cylinder can run stably under the condition that no power supply exists, the pontoon bridge gangplank can be overturned stably and can stop at any position, labor intensity is reduced, and work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a hydraulic device for driving and controlling the overturning of a pontoon springboard. Background technique [0002] In the past, the overturning of the pontoon springboard was generally controlled by manpower at first, relying on manpower to pull up the pontoon bridge springboard and turn it in place. The work intensity of the operators is high and the efficiency is low. Moreover, the heavy pontoon springboard poses a threat to the safety of the operator. Unfavorable effects, so there was a form of hydraulic device driving the pontoon springboard to turn over. The cylinder piston rod in the hydraulic system was used to connect the pontoon springboard, and the piston rod was pushed out or retracted by hydraulic oil to realize the overturning of the pontoon springboard. Because during the overturning process, when the pontoon springboard is in a vertical state, the pon...
