Description

Tubular pile bending test detection device Technical Field The utility model relates to the field of pipe pile bending resistance detection, in particular to a pipe pile bending resistance test detection device. Background In the pipe pile bending resistance detection process, the pipe pile is usually placed on a supporting frame of a base, and concentrated load is applied in the pipe pile span (the pressing block is driven by a hydraulic cylinder to apply pressure), so that bending deformation is generated. The bending strength and rigidity of the pipe pile can be determined by measuring the mid-span deflection and strain change of the test sample. However, the existing detection device has a plurality of inconveniences and potential safety hazards in the operation process. For example, in order to facilitate placement of the pipe pile, existing detection devices require a detachable pull rod to be provided on the side of the support boom to which the hydraulic cylinder is mounted. The bottom of the pull rod is rotationally connected with the base (as shown in fig. 4), the pull rod is required to be rotated and laid down when the pipe pile is placed, and the pull rod is rotated and raised after the pipe pile is placed and is clamped and fixed with the end part of the supporting cantilever. However, since the hydraulic cylinder applies a large pressure, the diameter of the tie rod is large to secure the stability of the support boom, resulting in a heavy weight thereof. In the rotation process of the pull rod, the pull rod needs to be pushed by multiple people in a resultant force, so that the pull rod is labor-consuming and easy to generate danger. Disclosure of utility model In order to solve the problems, the utility model provides a pipe pile bending resistance test detection device. The utility model is realized by the following technical scheme: The utility model provides a tubular pile bending test detection device, includes the support cantilever that base and middle part set up, is provided with hydraulic pressure tester on this support cantilever, and support cantilever one side is provided with the pull rod that is used for with base swing joint, and the top of pull rod is provided with the slip dolly that can remove to the base outside along the removal track. Further alternatively, the sliding trolley comprises a trolley body arranged on the inner side of the moving track, a plurality of moving wheels supported on the moving track are arranged on the trolley body, a supporting seat rotationally connected with a rotating shaft is arranged in the middle of the trolley body, and the center of the rotating shaft is fixedly connected with the top of the pull rod. Further alternatively, the movable rail is fixedly connected with one side of the supporting cantilever, and the outer part of the movable rail is fixedly connected with the side end of the base through the lateral supporting frame. Further alternatively, the center of the moving rail is provided with a through slot extending toward the end of the supporting cantilever and passing through the pull rod. Further alternatively, the connection end of the movable rail and the supporting cantilever is inserted with a limit screw for limiting the sliding trolley.
