The invention discloses a loaded oil cylinder positioning system of a shield segment testing machine. The loaded oil cylinder positioning system is composed of an oil cylinder bracket, sliding rails and oil cylinder rotary lifting mechanisms, wherein the sliding rails are connected with a self-balancing counter-force core cylinder of the shield segment testing machine, the oil cylinder bracket is connected with the sliding rails and used for supporting a loaded oil cylinder, the oil cylinder rotary lifting mechanisms are located above the self-balancing counter-force core cylinder and used for vertically lifting the loaded oil cylinder, and each oil cylinder rotary lifting mechanism is composed of a rotation support, a motor, an I-shaped steel supporting beam and an electric block. According to the loaded oil cylinder positioning system, the height positions of vertical brake devices on the sliding rails can be adjusted by screwing and unscrewing pre-fastening bolts, then the height positions of bracket sliding claws and the oil cylinder bracket are adjusted, and therefore the height position of the loaded oil cylinder is set in an adjustable mode.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a loading cylinder positioning system of a shield segment testing machine. Background technique [0002] The loading system is an important part of the shield segment testing machine. The loading system in the prior art is usually composed of a self-balancing reaction force core tube, a loading cylinder positioning system, a cylinder force application system, a test piece pad beam and a loading beam system, and an axial force loading system, etc. The function is to simulate continuously distributed water and soil pressure. , formation resistance and ground overload and other loads. The loading system is the most important basic system of the shield segment testing machine, and its composition structure is the main structure of the shield segment testing machine. [0003] The loading cylinder positioning system is a subsystem of the loading system of the shield seg...
