Description

Technical Field

[0001] The utility model relates to the technical field of building materials detection, in particular to a device for detecting the strength of building steel. Background Technique

[0002] The tensile strength test of steel is used to determine the maximum bearing capacity of steel under tensile force.

[0003] When detecting the tensile strength of steel, the traditional detection method is to first move the steel sample to one side of the testing machine, and clamp and fix both ends of the steel sample through clamps.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0025] The present invention provides a device for detecting the strength of building steel as shown in Figures 1-4 which includes a testing machine 1 and further includes:

[0026] A clamping assembly 2, the clamping assembly 2 is arranged on one side of the testing machine 1, the clamping assembly 2 includes a clamping frame 201, a connecting block 202 is inserted and connected inside the clamping frame 201, a clamping block 203 is arranged on one side of the connecting block 202, and a positioning groove 204 adapted to the steel is opened on one side of the clamping block 203

[0027] An extrusion assembly 3, the extrusion assembly 3 is arranged on one side of the connecting block 202, and the extrusion assembly 3 is used to drive the connecting block 202 to move

[0028] A fixing assembly 6, the fixing assembly 6 is arranged at the connection between the connecting block 202 and the clamping block 203, and the fixing assembly 6 is used to limit the moving direction of the clamping block 203

[0029] A limiting assembly 4, the limiting assembly 4 is arranged on the top of the clamping block 203, and the limiting assembly 4 is used to limit the movement of the clamping block 203

[0030] It should be noted that the set testing machine 1 is a universal testing machine with the model JT-969, and the number of the set clamping assemblies 2 is two. One of the clamping assemblies 2 is fixed and immovable, and the other clamping assembly 2 is fixed on the testing arm. The object to be detected is pulled by moving the clamping assembly 2, so as to conduct a tensile test. The positioning groove 204 opened on one side of the clamping block 203 is adapted to the steel to be detected. When the steel needs to be clamped, the steel is placed between the clamping frame 201 and the clamping block 203, and the steel is inserted and connected inside the positioning groove 204. The movement of the steel is restricted by the positioning groove 204. Then, the pressing assembly 3 drives the connecting block 202 and the clamping block 203 to move towards one side of the steel, and the end of the steel is clamped by the clamping block 203 and the inner wall of one side of the clamping frame 201. The set fixing assembly 6 and limiting assembly 4 are used to limit the clamping block 203 on one side of the connecting block 202, and at the same time, the clamping block 203 is replaced when testing different steels.

[0031] Specifically, the pressing assembly 3 includes a threaded rod 303 inserted and connected to the inner wall of one side of the clamping frame 201. A handle 304 for rotating the threaded rod 303 is arranged on one side of the threaded rod 303. A limiting groove 301 is opened on the other side of the connecting block 202. The other end of the threaded rod 303 is fixedly connected with a limiting block 302. The limiting block 302 is inserted and connected inside the limiting groove 301. The horizontal longitudinal sections of the limiting groove 301 and the limiting block 302 are both set as convex shapes.

[0032] It should be noted that the set limiting block 302 is composed of two cylinders with different diameters. The opened limiting groove 301 is adapted to the set limiting block 302. During use, the limiting block 302 can rotate inside the limiting groove 301 but cannot move. The set threaded rod 303 is inserted and connected to one side of the clamping frame 201 in a threaded manner. When the position of the clamping block 203 needs to be moved, the handle 304 is used to drive the threaded rod 303 to rotate. The threaded rod 303 moves on one side of the clamping frame 201 that is threadedly connected to it and cannot rotate through rotation. The moving threaded rod 303 drives the connecting block 202 and the clamping block 203 to move, so as to complete the clamping and release of the steel.

[0033] Specifically, the fixing assembly 6 includes a fixing groove 602 opened on one side of the connecting block 202. A fixing block 601 is fixedly connected to one side of the clamping block 203. The fixing block 601 is inserted and connected inside the fixing groove 602. The limiting assembly 4 includes a driving block 401 arranged at the top of the clamping block 203. A limiting block 403 is fixedly connected to the bottom end of the driving block 401. A limiting groove 402 is opened at the top of the clamping block 203. The limiting block 403 is inserted and connected inside the limiting groove 402. A moving member 5 for driving the driving block 401 to move is arranged at the bottom end of the driving block 401.

[0034] It should be noted that the set fixed block 601 is adapted to the opened fixed groove 602, and both are cubes. When it is necessary to fix the position of the clamping block 203, the fixed block 601 on one side of the clamping block 203 is inserted into the inside of the fixed groove 602, so that the moving direction of the fixed block 601 is limited to the direction of inserting into the fixed groove 602, and the moving direction of the clamping block 203 is limited by the fixed block 601 that limits the moving direction; the set driving block 401 is driven by the moving member 5. When the fixed block 601 is inserted into the inside of the fixed groove 602, the limiting groove 402 at the top of the clamping block 203 is aligned with the limiting block 403 at the bottom of the driving block 401, and the moving member 5 drives the limiting block 403 and the limiting block 403 to move to one side of the limiting groove 402, and the limiting block 403 is moved into the inside of the limiting groove 402. Due to the pulling of the limiting block 403, the clamping block 203 and the fixed block 601 on one side of the clamping block 203 cannot move along the direction of inserting into the fixed groove 602, so that the clamping block 203 and the fixed block 601 cannot move further, and the clamping block 203 is restricted to one side of the connecting block 202.

[0035] Specifically, the moving member 5 includes a connecting rod 501 fixedly connected to the bottom end of the driving block 401. The bottom end of the connecting rod 501 is fixedly connected with a pushing plate 504. The top end of the pushing plate 504 is fixedly connected with an elastic ring 502. The connecting rod 501 is inserted through the middle of the elastic ring 502. A cavity 503 is opened at the top of the connecting block 202. The pushing plate 504 is inserted through the inside of the cavity 503. The top end of the elastic ring 502 is fixedly connected to the inner wall of the top end of the cavity 503. The connecting rod 501 is inserted through the inner wall of the top end of the cavity 503.

[0036] It should be noted that the set pushing plate 504 is adapted to the opened cavity 503. During use, the pushing plate 504 can slide inside the cavity 503. The set elastic ring 502 is made of rubber and is used to push the pushing plate 504 towards the inner wall of the bottom end of the cavity 503 during use. When the elastic ring 502 is squeezed, the elastic ring 502 will deform, so that the pushing plate 504 can move towards one side of the elastic ring 502. When the pushing plate 504 loses the pulling force, the elastic ring 502 will recover its deformation and push the pushing plate 504 towards the side away from the elastic ring 502. The set connecting rod 501 is used to connect the pushing plate 504 inside the cavity 503 and the driving block 401 outside the cavity 503.

[0037] Further, when it is necessary to move the driving block 401 to the side away from the connecting block 202, the driving block 401 drives the connecting rod 501 and the pushing plate 504 to move. The elastic ring 502 deforms under the extrusion of the pushing plate 504. When it is necessary to return the driving block 401 to its original position, release the pulling force on the driving block 401, so that the pushing plate 504 loses the pulling force. The elastic ring 502 resumes its deformation and drives the pushing plate 504 to move to the side away from the driving block 401. The pushing plate 504 drives the connecting rod 501 and the driving block 401 to move, thereby resetting the driving block 401.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
