Description

Technical Field

[0001] The present application relates to the technical field of strength testing equipment, and more specifically, to a steel strength testing device. Background Art

[0002] Modern buildings usually use a lot of steel, such as steel bars, steel plates and steel sections. The strength of construction steel refers to the ability of the material to resist fracture under external forces. The strength of construction steel is an important standard that must be measured during the use of the material, and these steels usually have to pass the mechanical property test before they can be used.

[0003] The document with prior art publication number CN218823643U provides a steel strength detection device, which is small in size, easy to carry and convenient to use at the construction site; the connecting component prevents the pressure sensor from directly contacting the force application point of the steel, thereby avoiding damage to the sensor; at the same time, the rectangular hole on the base limits the L-shaped pressure plate, so that the L-shaped pressure plate will not slide during the process of fixing the steel, thereby ensuring that the steel will not move during the detection process and improving stability.

[0004] However, the above device can only be used to detect plates with smaller thickness. When testing columnar steel or thicker steel, the two ends of the steel will be lifted during the bending process. The L-shaped pressure plate will prevent the ends of the steel from lifting, thereby affecting the accuracy of the test. In view of this, we propose a steel strength detection device. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The purpose of this application is to provide a steel strength testing device, which solves the technical problem in the prior art that the steel ends are warped during the bending strength test, and the testing equipment cannot provide a telescopic space for the warping, which affects the test accuracy. It achieves the technical effect of effectively providing a release space for the warped ends of the steel and reducing the risk of steel missiles.

[0007] 2. Technical solution

[0008] The embodiment of the present application provides a steel strength detection device, including a base;

[0009] A support frame is fixedly mounted on the base, a telescopic cylinder is fixedly mounted on the support frame, and a pressure block is fixedly mounted on the output shaft of the telescopic cylinder;

[0010] A cushion block is fixedly mounted on the base, and the cushion block is slidably connected to two groups of support blocks;

[0012] The support block is rotatably connected with a support wheel, which is used for supporting the steel;

[0013] The support block is rotatably connected to a limiting assembly for limiting the position of the steel material.

[0014] By adopting the above technical solution, the rotation of the double-threaded screw drives the two groups of support blocks to move toward or relative to each other, thereby realizing the adjustment of the support spacing. At the same time, the two support blocks can also be effectively fixed by the double-threaded screw to ensure the stability of the support during the test. The setting of the limit assembly can effectively avoid the flying of steel during the bending test and improve the safety of the test.

[0019] An elastic piece is sleeved on the plug-in rod, one end of the elastic piece is fixedly connected to the plug-in rod, and the other end is fixedly connected to the limiting frame.

[0020] By adopting the above technical solution, after the steel to be tested is placed on the two support wheels, the plug-in rod is pulled to insert the support shaft into the limiting hole on one side. Under the action of the elastic member, the plug-in rod is inserted into the limiting hole on the other side. The limiting frame rotates on the limiting hole through the plug-in rod and the support shaft, thereby effectively limiting the steel to a certain extent and reducing the risk of steel flying during the bending test.

[0021] As an optional solution of the technical solution of this application document, a rotating roller is rotatably connected to the limiting frame.

[0022] By adopting the above technical solution and setting the rotating roller, the obstruction of bending movement during steel testing is reduced, thereby ensuring the normal progress of the test.

[0023] As an optional solution of the technical solution of the present application document, a plurality of limit rods are fixedly installed on the support frame, and the limit rods are distributed on both sides of the support block.

[0024] By adopting the above technical solution, when the steel is bent, the limit rods on both sides can effectively limit the two sides of the bent steel, reduce the risk of the steel flying out, and further improve the safety of the test;

When testing the steel, it provides bending space for the steel, thereby reducing the impact on the bending strength test of the steel and improving the accuracy of the test.

[0040] A cushion block 5 is fixedly installed on the base 1, and a slide groove 6 is opened on the cushion block 5. Two groups of sliders 7 are slidably connected in the slide groove 6. A support block 8 is fixedly installed on the slider 7. A double-threaded screw rod 9 is rotatably connected to the support frame 2. A connecting plate 10 is fixedly installed on the support block 8. The support block 8 is threadedly matched with the double-threaded screw rod 9 through the connecting plate 10. The rotation of the double-threaded screw rod 9 drives the two groups of support blocks 8 to move toward or relative to each other, thereby realizing the adjustment of the support spacing. A screw block is fixedly installed on the middle part of the double-threaded screw rod 9, and the double-threaded screw rod 9 is driven to rotate by the screw block to reduce the difficulty of rotation. The two support blocks 8 can also be effectively fixed by the double-threaded screw rod 9 to ensure the stability of the support during testing.

[0041] A support wheel 11 is rotatably connected to the support block 8. The two ends of the support wheel 11 are convex and the middle is concave.
