Description

Technical Field

[0001] The utility model relates to the technical field of concrete compression fatigue detection, in particular to a steel fiber concrete compression fatigue detection device. Background Art

[0002] Steel fiber concrete is a new type of multiphase composite material formed by adding randomly distributed short steel fibers to ordinary concrete. These randomly distributed steel fibers can effectively hinder the expansion of micro cracks inside the concrete and the formation of macro cracks, significantly improving the tensile, bending, impact and fatigue resistance of the concrete. The compressive fatigue test equipment is used to test its performance.

[0003] A steel fiber concrete compressive fatigue testing device disclosed in Chinese patent CN 220207339 U, the steel fiber concrete compressive fatigue testing device, the inner wall of the protective baffle pushes the linkage plate, so that the linkage plate pushes the fixed clamping plate to clamp the material, improves the stability of the material during testing and ensures the accuracy of the test, drives the conveyor chain on the surface to move through the rotation of the conveyor sprocket, so that the conveyor chain drives the material to be automatically transported and enters the groove of the limit plate to wait for testing, improves the practicality of the device, facilitates the loading of materials and improves the efficiency of the test, and when transporting materials, the hollow design of the conveyor chain surface facilitates the falling of debris into the collection box, and then the debris in the collection box enters the cavity of the mounting frame through the opening of the mounting frame for collection, and the user quickly cleans the collected debris through the rotating doors on both sides of the mounting frame, improves the practicality of the device and facilitates cleaning and maintenance.

[0004] However, while solving the problem, the steel fiber concrete compressive fatigue testing equipment has the following disadvantages: by setting a linkage plate to push the fixed clamp to clamp the material, the fixed clamps on both sides will support the steel fiber concrete block, which will lead to deviation in the test result; by setting a hollow conveyor chain belt, debris can fall through the gap into the collection box, which is not convenient for concrete debris to fall as a whole, and larger or entire steel fiber concrete blocks will be stuck on the conveyor chain belt, which is not convenient for later cleaning.

[0028] The positioning device 3 includes a push rod 301, both ends of which are fixedly connected to a fixed block 302, the fixed block 302 is slidably engaged in the slide groove 6, one side of the fixed block 302 is movably engaged in the threaded block 304, the center position of the threaded block 304 is penetrated by a first threaded rod 305, one end of the first threaded rod 305 is fixedly connected to a rocker, and the push rod 301 is arranged in cooperation with the first threaded rod 305 to make the push rod 301 move laterally on the fixed platform 1, so that the steel fiber concrete block dropped from the conveyor belt 10 to the fixed platform 1 is pushed forward to the specified position.

[0029] The push rod 301 is movably connected to a limit block 307 on one side of the fixed block 302 away from one end of the threaded block 304. A second threaded rod 306 is connected through the center of the limit block 307. One end of the second threaded rod 306 is fixedly connected to a rocker.
