The invention relates to a safety type hydraulic-pneumatic spring device applied to a ship lift. The safety type hydraulic-pneumatic spring device comprises a support, a measuring shaft, a lower flange, a guide shaft sleeve, a self-lubricating bearing, a hydraulic-pneumatic spring oil cylinder, a pull rod, an upper flange, a self-lubricating sliding sleeve, an air bag type energy accumulator and an oil pipe; the lower end of the support is fixedly arranged on a ship lift chamber structure, and a hinge shaft in the middle of the hydraulic-pneumatic spring oil cylinder is supported on the support through the self-lubricating bearing; the end part of an upper piston rod is connected with the upper flange through threads, the lower end of a lower piston rod of the hydraulic-pneumatic spring oil cylinder is assembled with a mounting hole of the lower flange in a clearance fit mode through the guide shaft sleeve, and the lower end of the measuring shaft and a bottom beam of a gear bracket mechanism form a hinged structure; and the upper end of the pull rod sleeves an inner hole of a self-lubricating shaft sleeve provided with a flange, the top of the pull rod is positioned by a nut, thelower end of the pull rod is hinged with a bottom beam of the gear bracket mechanism through the measuring shaft at the bottom, and the air bag type energy accumulator communicates with a rodless cavity through the oil pipe. The function of stable transition from a pinion and a rack to a rotary screw and a nut column of a safety mechanism in the vertical support of a ship chamber is realized, andthe safety is improved.
Description
technical field [0001] The invention relates to a hydraulic-pneumatic spring device, more specifically, a rack-and-pinion climbing vertical ship lift that is suitable for unbalance accidents in the ship-bearing compartment, through the movement of double piston rods and the corresponding displacement-load mechanism The safety type hydropneumatic spring device and its load transfer method realize the two-way accident load transfer of the ship bearing compartment from the rack and pinion of the driving mechanism to the safety mechanism. Background technique [0002] As a navigation facility, the vertical ship lift is increasingly widely used in water conservancy projects because of its short dam crossing time and its suitability for high dam navigation. The fully balanced rack and pinion vertical ship lift is used in water conservancy projects where large ships pass through dams due to its high safety, such as the 3000t rack and pinion climbing vertical ship Two climbing verti...
