This invention discloses a bridge pot bearing and control system based on system conversion. A first bearing body and a second bearing body are stacked from top to bottom. The first bearing body has a first mounting plate, and an adjustment component is installed below the first mounting plate. The second bearing body has a second mounting plate, and a test component is installed on the second mounting plate. The test component connects with the adjustment component. While performing pressure testing, the test component, in conjunction with the adjustment component, enables the conversion between three states: fixed pot bearing, unidirectional movable pot bearing, and bidirectional movable pot bearing. This invention monitors the stress on the bearing in real time, calculates the bridge shear force based on the reaction force, and derives the bridge shear force amplification factor under dynamic loads, thus improving bridge design methods and making bridge design safer and more reliable. It can realize the functions of a fixed bearing, a unidirectional movable bearing, or a bidirectional movable bearing, and achieve mutual conversion between bearing types.

This utility model relates to a tooling for replacing axle pins, including a tooling base, a traveling mechanism, a lifting mechanism, a telescopic mechanism, a counterweight mechanism, a jack support, and a clamp. The lifting mechanism drives the furniture to rise and fall, the telescopic mechanism drives the furniture to move left and right, the jack support can adjust the angle of the jack, and the counterweight mechanism consists of a counterweight box welded to the tail of the telescopic mechanism. A counterweight block smaller than the size of the counterweight box is placed inside the counterweight box. This technical solution is used to replace the current method of using gas cutting to remove axle pins and using a sledgehammer to install axle pins in the replacement of axle pins in mechanical equipment.
