Abstract
Description
Technical Field
[0001] The utility model relates to a tensile strength test platform for a container corner post. Background Art
[0002] As a widely used transportation tool, the demand for containers is increasing day by day. The main load-bearing and stress-bearing components of a container are the corner posts at the four corners of the container, and the strength of the corner posts directly determines the overall strength and stability of the container.
[0003] The corner posts at the four corners of the container mainly include tubular columns and corner fittings welded at both ends of the columns. The strength of the corner posts refers to the overall tensile strength of the corner posts. The welding strength between the columns and the corner fittings at both ends and the material of the columns will affect the tensile strength of the corner posts.
[0004] Containers are widely used, and the goods loaded in the containers vary greatly. Some goods are heavy and some are light. When encountering heavy goods, the corner posts may be damaged during transportation, that is, the corner fittings are welded open or the columns are deformed, which will affect the normal use of the container.
[0005] In order to ensure the quality of the container and prevent the damage of the corner posts during the transportation of goods, the tensile strength of the corner posts should be tested. Only when the tensile strength of the corner posts reaches a certain threshold can they be used. There is no special test device for the tensile strength of corner posts in the prior art. Content of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide a tensile test platform for container corner posts, which can conveniently test the tensile strength of container corner posts after the application of the utility model.
[0007] To solve the above technical problem, the utility model provides a tensile strength test platform for container corner posts. The container corner post includes a column and corner fittings welded at both ends of the column. The end of the corner fitting has a long strip hole. The tensile strength test platform for container corner posts includes a working platform. A support frame is fixed at the front of the working platform, and a tension frame is arranged at the rear. A hydraulic pulling mechanism for horizontally pulling the tension frame backward along the working platform is also fixed on the working platform behind the tension frame. Rotary locks for horizontally locking the container corner post between the support frame and the tension frame are respectively installed on the support frame and the tension frame.
[0008] As an improvement of the utility model, the hydraulic pulling mechanism includes an oil cylinder support, two hydraulic cylinders and a connecting ear arranged in sequence on the working platform at the rear side of the pulling frame. The oil cylinder support is fixed on the working platform. The cylinder bodies of the two hydraulic cylinders are fixed on the oil cylinder support, and the ends of the piston rods are fixed on the connecting ear. It also includes two sliding columns arranged on the left and right sides of the oil cylinder support and the two hydraulic cylinders. The two ends of the two sliding columns are respectively fixedly connected with the left and right sides of the pulling frame and the connecting ear.
[0009] As a further improvement of the utility model, the rotary lock includes a rotating rod and a strip-shaped lock block. The rotating rod is rotatably installed on the support frame and the pulling frame. The strip-shaped lock block is installed at the end of the rotating rod. The external contour size of the strip-shaped lock block is smaller than the contour size of the long strip-shaped hole at the end of the corner fitting, and the length of the strip-shaped lock block is greater than the width of the long strip-shaped hole.
[0010] Furthermore, the support frame includes a support vertical plate fixed on the working platform. Front and rear support rib plates are respectively connected between the front and rear sides of the support vertical plate and the working platform. The rotating rod is rotatably installed on the support vertical plate.
[0011] Still further, the working platform is arranged in a way that it is narrower at the front and wider at the rear.
[0012] When the utility model is in use, first drive the hydraulic cylinder to adjust the position of the pulling frame. Then place the container corner post to be tested between the support frame and the pulling frame. Rotate the rotating rod of the rotary lock to make the lock block located in the long strip-shaped hole of the corner fitting. Rotate the rotating rod of the rotary lock again to make the lock block turn to the horizontal state to lock the corner fitting. Then drive the oil cylinder to pull the pulling frame to slide backward. The hydraulic station that provides power for the oil cylinder can conveniently read the pulling force value. When the pulling force value reaches a preset threshold, stop the test. Then observe whether the corner fitting is welded open and whether the column is deformed, and then it can be intuitively judged whether the container corner post is qualified. By using the utility model to test the tensile strength of the container corner post, it can be judged whether the product is qualified, and then the strength and stability of the whole container during transportation can be effectively guaranteed. In the utility model, a hydraulic pulling mechanism is adopted, and the pulling force value can be conveniently read through the hydraulic station; in the support frame, front and rear support rib plates are respectively connected between the front and rear sides of the support vertical plate and the working platform, which can improve the overall strength of the support frame; the working platform is arranged in a way that it is narrower at the front and wider at the rear. Such a structural design can make the whole utility model more compact, and can save materials and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS
