Description

Technical Field

[0001] This utility model belongs to the field of pressure testing technology, specifically relating to a pressure testing device for a steel pipe concrete pier. Background Technology

[0002] Concrete-tube steel piers are commonly used supporting structures in engineering. They mainly consist of an outer arch structure and an inner concrete layer, combining the advantages of both steel and concrete to achieve greater load-bearing capacity. Concrete-tube steel piers are a special type of structural component that combines the advantages of steel tubes and concrete. They are typically used for bridge piers, large-diameter columns in buildings, and other tall structures. Concrete-tube steel refers to components formed by filling concrete within steel tubes. Concrete-tube steel structures were initially used for bridge piers and gradually transitioned to columns in buildings.

[0003] In existing related technologies, in order to facilitate the determination of the pressure state of steel-concrete composite piers at different locations during pressure testing, it is not possible to move the pressure head longitudinally to test different points of the steel-concrete composite pier. Therefore, it is urgent to design a pressure testing device for steel-concrete composite piers to address these issues. Utility Model Content

[0013] The beneficial effects are:

[0014] This utility model discloses a pressure testing device for steel pipe concrete piers. Through a set testing execution mechanism, a second motor drives a second lead screw to rotate, which in turn drives a lifting platform, a longitudinal platform, an electric hydraulic cylinder, and a pressure head to move up and down. After moving to a certain position, it stops, and a second electric telescopic rod is activated to push the L-shaped platform, the electric hydraulic cylinder, and the pressure head to move longitudinally. This causes a scale fixedly installed on the L-shaped platform to move longitudinally back and forth on one side of a scale fixedly set on the longitudinal platform, controlling the longitudinal movement distance of the pressure head. The electric hydraulic cylinder is then activated to move the pressure head downwards to test different longitudinal positions of the steel pipe concrete pier. Pressure is controlled by a pressure gauge, ensuring testing effectiveness. The addition of a longitudinal pressure head improves testing efficiency and makes the device easy to use.

The distance is controlled by moving the scale 310 on the scale platform 309. After moving to the new position, the pressure test process can be repeated.
