Moving cross beam lifting system of ten thousand ton stage loading test device

Abstract

The invention discloses a moving cross beam lifting system of a ten thousand ton stage loading test device. The moving cross beam lifting system comprises four moving cross beam lifting hydraulic cylinders and a hydraulic driving system, wherein a cylinder tube of each moving cross beam lifting hydraulic cylinder is connected with a top beam through a cylinder tube fixing element; the lower end of a piston rod is connected with the bottom of a moving cross beam through a piston rod connecting element; cavities for accommodating the cylinder tubes are formed in the moving cross beam; each group of moving cross beam lifting hydraulic cylinder is provided with a displacement sensor and a pressure sensor; the hydraulic driving system is used for driving the moving cross beam lifting hydraulic cylinders to operate. The moving cross beam lifting system of the ten thousand ton stage loading test device provided by the invention has the advantages that the continuous stepless adjustment in the vertical moving space can be realized; the operation of the whole system is simple; the automation degree is high; overload protection can be easily realized through hydraulic transmission; hydraulic elements can be lubricated by self; the service life of the system is long. The hydraulic elements realize the serialization, the standardization and the generalization, so that the manufacturing, the use and the maintenance are very convenient.

Description

technical field [0001] The invention belongs to the technical field of pressure test equipment for large-scale civil components and rubber test pieces, and in particular relates to a moving crossbeam lifting system for a 10,000-ton loading test device. Background technique [0002] With the development of urban construction, the number of high-rise buildings is increasing day by day, and the requirements for the rigidity, strength and earthquake resistance of building structures are getting higher and higher, and there is an urgent need for test equipment for super-heavy-load and super-large space structures. Together with the column, the base and the loading platform, the moving beam forms a continuously adjustable loading height space, which can meet the optimal test space required by test pieces of various sizes. When carrying out static and dynamic loading tests on specimens, a lifting system that can drive the moving beam to move quickly and smoothly in a large range in...
