Hydraulic vertical rotary experimental platform for fatigue test of tensile anchor plate

Abstract

The invention provides a hydraulic vertical rotary experimental platform for a fatigue test of a tensile anchor plate. The platform is characterized by comprising a bottom plate and a top plate. The edge of one side of the bottom plate is hinged to the edge of one side of the top plate; the bottom plate is placed on a foundation of a lab and is fixedly connected to the foundation and the top plateis used for bearing the tensile anchor plate and enabling the same in a stable vertical state; a hydraulic device is arranged between the bottom plate and the top plate for supporting the top plate;a movable connecting rod is arranged between the bottom plate and the top plate, too, and the fixing positions and angles of the two ends of the movable connecting rod and the bottom plate and the topplate can be adjusted, so that the included angle between the bottom plate and the top plate can be adjusted. The invention aims to provide the hydraulic vertical rotary experimental platform for thefatigue test of the tensile anchor plate to overcome defects in the prior art, and the platform not only can adjust the vertical rotary angle in the fatigue experiment of the tensile anchor plate, but also can simplify the test step angle, thereby solving the problems of high demand on fatigue experimental site and the like.

Description

technical field [0001] The invention relates to the technical field of anchor pull plate experiments, in particular to a hydraulic vertical rotation test platform for anchor pull plate fatigue tests. Background technique [0002] Cable-stayed bridges are one of the most popular types of long-span bridges in China. So far, more than 100 cable-stayed bridges of various types have been built in China. The anchorage area between the cable-stayed cable and the main girder of a cable-stayed bridge is one of the key structural components, where the force is concentrated and the structure is complex. At present, the cable girder anchorage forms of cable-stayed bridges mainly include anchor box type, ear plate type, anchor tube type and anchor pull plate type. The anchor plate has unique advantages such as simple structure, easy processing, and easy maintenance, and has been widely used. However, the anchorage area of ​​the anchor-stayed cable-beam type has the disadvantages of sud...
