The present invention relates to anti-sloshing LNG cargo tanks to mitigate a sloshing phenomenon. The anti-sloshing LNG cargo tank having a first barrier for preventing leakage of a cryogenic LNG, a second barrier and an insulation pad provided to supplement the first barrier, includes: an anti-sloshing bulkhead for partitioning a space in the LNG cargo tank into a plurality of spaces to reduce asloshing phenomenon of the LNG that moves in the LNG cargo tank; and a stool part united at a first surface thereof to an inner wall of an LNG carrier body and united at a second surface thereof to the anti-sloshing bulkhead to fasten the anti-sloshing bulkhead to the inner wall of the LNG cargo tank. The stool part is coupled to the first barrier and the second barrier and having the insulation pad therein, thus preventing the cryogenic LNG from leaking towards the inner wall of the LNG carrier body or from exchanging heat with the inner wall of the LNG carrier body.

The invention discloses a hydraulic excitation system of a tamping device. The hydraulic excitation system comprises more than one execution and control units, wherein, each execution and control unit comprises more than one pair of symmetric hydraulic cylinders; first operating cavities of the symmetric hydraulic cylinders are communicated via oil tubes, and second operating cavities of the symmetric hydraulic cylinders are communicated via oil tubes; one pressure oil inlet of an operating cavity of a de-execution mechanism of each four-way high-speed change valve with a rotary valve core iscommunicated with the first operating cavities of the symmetric hydraulic cylinders, and the other pressure oil inlet of the operating cavity is communicated with the second operating cavities; a supply pressure oil inlet of each four-way high-speed change valve with a rotary valve core is communicated with outlets of a throttle valve, and an oil return opening of each four-way high-speed change valve with a rotary valve core is communicated with a cooler; and the cooler is communicated with an air drier; and an outlet of a check valve is respectively communicated with an inlet of the throttle valve and an inlet of an electromagnetic relief valve, an inlet of the check valve is communicated with the output end of a hydraulic pump, and the input end of the hydraulic pump is communicated with an oil suction filter. By utilizing the hydraulic excitation system, continuous reversing control and stepless control of reversing frequency are realized under a high flow condition.

The invention relates to a flexible guiding special lift car stabilizing device and method. The device is composed of a stabilizing support, a connecting mechanism and a self-locking mechanism. The connecting mechanism comprises connecting plates, final limit cams and stabilizing bars, and the self-locking mechanism comprises rockers, return springs, driving bolts, bearings, driven bolts and pins. When a lift stops on a floor, a car door is opened to drive the connecting mechanism to release self locking, the stabilizing bars are pushed into a shaft support so as to stabilize the lift car, and the self-locking mechanism returns to the self-locking state. After unloading and loading, the car door is closed, the connecting mechanism is driven to release self locking, the stabilizing bars are withdrawn, the self-locking mechanism performs self locking again, and the lift runs normally. The problem that the lift car sways when people or cargos enter or exit from the flexible guiding mining lift is solved, various safety problems caused by partial swaying during rerunning of the lift car are avoided, the lift car can be started stably after stopping on one floor, reliability and stability of the lift are improved, driving does not need to be set independently, and the flexible guiding special lift car stabilizing device is simple in structure, good in lift car stabilizing effect, low in cost and safe and reliable.
