The invention discloses a standardized stirrup lifting tool in the technical field of stirrup lifting, comprising a trolley, a lifting ring and a motor, and is characterized in that: it also comprises a fixed platform, a telescopic vertical pole, an oil storage tank and a main oil pipe; a plurality of the lifting rings are fixedly mounted on both sides of the trolley, a plurality of the fixed platforms are arranged and mounted above the trolley, the telescopic vertical pole is vertically mounted in the middle of the fixed platform, the main oil pipe is fixedly mounted at the lower end of the fixed platform, and the main oil pipes are sealed and connected to each other, the driving mechanism is mounted on the trolley, and the driving mechanism is sealed and fixedly connected to the main oil pipes on both sides; the oil storage tanks equal to the fixed platforms are fixedly connected to the fixed platforms respectively, and the oil storage tanks are connected to the main oil pipes on the corresponding fixed platforms, so that the height of the vertical pole changes with the storage height of the stirrup, thereby reducing the total distance of lifting and lowering the stirrup, alleviating the physical exertion of workers during operation, and reducing the risk of stirrups falling from their hands and injuring people.

This invention discloses a miniature bidirectional crawling robot based on vibration mode control, comprising a support frame, a drive device, and a power system. The power system consists of an elastic element, a flexible four-bar linkage, and crawling feet. One end of the elastic element is fixed to the support frame, and the other end is connected to the flexible four-bar linkage. The other end of the flexible four-bar linkage is fixed, with the crawling feet connected in its middle section. The elastic element can generate different vibration modes under different frequency excitations. The drive device can drive the elastic element to undergo forced vibration, which in turn drives the crawling feet relative to the ground through the flexible four-bar linkage to achieve bidirectional crawling. When the power system is in first-order vibration, the robot crawls forward; when the power system is in second-order vibration, the robot crawls backward. Thus, by changing the vibration mode of the elastic element, the robot can be controlled to achieve bidirectional crawling motion. This invention has a simple structure, high reliability, convenient bidirectional motion control, great miniaturization potential, and fast crawling speed.

The present application provides a top-lock pull-out type connecting device and an immersed tube construction ship; the connecting device comprising a support member, fixedly connected to the load-bearing element and located on a side of the load-bearing element facing the borne element; a sliding member, been able to slide relative to the load-bearing element in a connection direction of the load-bearing and borne elements; an ejector rod, used to push the sliding member, fixedly connected to the borne element; a first locking member, used to lock the ejector rod, movably connected between an end of the sliding member close to the borne element and the support member, and can to be driven by the sliding member to be close to or away from the ejector rod; and a second locking member, used to lock the sliding member, and connected between an end of the sliding member away from the borne element and the load-bearing element.
