[0002] In modern industrial construction, due to its high strength, light weight and good plasticity, steel structures are widely used in large buildings, bridges and pressure vessels. However, these applications have extremely high requirements for the quality of materials, especially strict standards for the safety and reliability of structures. Therefore, the quality detection of steel structures is particularly important. As a device for evaluating the dynamic mechanical properties of materials, the impact testing machine plays a key role in this field.

[0003] In the prior art, during the use of traditional impact machines, due to the inconsistency of the lengths of steel specimens, it is crucial to ensure that the specimen slots are exactly located between the two support blocks. This usually requires the operator to manually measure the placement position of the specimen to avoid position deviation. However, when using the impact machine, the operator needs to manually adjust the hammer to impact the steel specimen. During this process, if the steel specimen is not fixed, the steel specimen is likely to shift, thereby causing the slot position to move and affecting the test accuracy.

[0004] Therefore, an impact machine for steel structure detection is needed to solve the problem that the existing impact machine does not effectively fix the positions on the front and back sides of the steel specimen, resulting in its easy shift and affecting the test accuracy.

All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] Embodiment 1: Please refer to Figures 1 - 10 , the present utility model provides a technical solution: an impact machine for steel structure detection, including a body 1. Two support blocks 2 are installed on the front side of the bottom of the body 1. An installation groove 16 is opened in the middle of the support block 2. A placement block 3 is inserted into the inner wall of the installation groove 16. A moving groove 6 is opened in the middle of the placement block 3. A clamping plate 12 is installed on the inner wall of the moving groove 6. Two fixing rods 13 are inserted into the middle of the clamping plate 12; the fixing rods 13 are installed on the top of the inner wall of the moving groove 6. The front and rear clamping plates 12 are symmetrically arranged, so as to adjust the distance between the two clamping plates 12 to adapt to steel specimens of different lengths, and then fix the front and rear sides of the steel specimen to prevent it from shifting.

[0029] When using the body 1, pull the clamping plates 12 to the front and rear sides respectively, so that the bottom slides along the inner wall of the moving groove 6, and at the same time the upper part slides along the outer sides of the two fixing rods 13, so as to conveniently adjust the positions of the two clamping plates 12. Then place the steel specimen directly on the tops of the two placement blocks 3 and be restricted by the front and rear clamping plates 12, so that the slot on the left side is kept between the two support blocks 2, so as to conveniently fix the front and rear positions of the steel specimen and prevent it from shifting, thereby improving the accuracy of the test.

[0030] The second embodiment: on the basis of the first embodiment, in order to fix the position of the rear clamping plate 12 after adjustment for subsequent use, a slide groove 2 9 is provided at the bottom of the clamping plate 12, and two movable plates 11 are installed on the inner wall of the slide groove 2 9. The movable plate 11 plays a limiting role, thereby preventing the clamping rod 8 from being pushed out of the clamping plate 12. The separated sides of the left and right movable plates 11 are both installed with clamping rods 8, and an elastic member 10 is installed between the adjacent sides. A plurality of clamping grooves 7 are provided on the left and right sides of the inner wall of the movable groove 6; the elastic member 10 is arranged on the inner wall of the slide groove 2 9, and the separated ends of the clamping rods 8 on the left and right sides penetrate the bottom of the clamping plate 12 and are plugged into the inner wall of the clamping groove 7, so that the elastic force of the elastic member 10 is utilized to drive the movable plate 11 to slide on the inner wall of the slide groove 2 9, and at the same time drive the two clamping rods 8 to move backwards and insert into the inner wall of the clamping groove 7, so as to facilitate the position fixing of the clamping plate 12 after adjustment, and then facilitate subsequent use.

[0031] Pull the clamping plate 12 to the front and rear sides, let its bottom slide along the inner wall of the movable groove 6, and let its upper part slide along the outer side of the two fixed rods 13. At this time, the two clamping rods 8 will be pushed and squeezed between the clamping groove 7, and the clamping rod 8 will gradually shrink to the inner wall of the slide groove 2 9, and at the same time, the two movable plates 11 will be driven to squeeze the elastic member 10 therebetween. After the adjustment is completed, the elastic force of the elastic member 10 is used to drive the movable plate 11 to move, and drive the separated ends of the two clamping rods 8 to be inserted into the inner wall of the clamping groove 7 that matches it after adjustment, thereby fixing the position of the clamping plate 12 after adjustment.

[0032] Embodiment 3: On the basis of embodiment 2, in order to facilitate the disassembly of the placement block 3 and to enable the operator to disassemble and assemble without the aid of tools, a connecting block 4 is installed on the left side of the placement block 3, a plug-in slot 15 is provided on the left side of the inner wall of the installation slot 16, a slide slot 5 is provided on the top right side of the placement block 3, a shifting block 14 is installed on the inner wall of the slide slot 5, a spring 17 is installed on the left side of the shifting block 14, and a limiting slot 18 is provided on the right side of the inner wall of the installation slot 16; the connecting block 4 is plugged into the inner wall of the plug-in slot 15, and the left end of the spring 17 is installed on the inner wall of the slide slot 5, so that the right side of the connecting block 4 is always plugged into the inner wall of the limiting slot 18 by utilizing the elastic force of the spring 17; the right side of the connecting block 4 passes through the placement block 3 and is plugged into the inner wall of the limiting slot 18, so that by shifting the connecting block 4 to the left and driving its right side to disengage from the limiting slot 18, the restriction on the placement block 3 is released, thereby facilitating the removal of the placement block 3.

[0033] When it is necessary to maintain the placement block 3, first push the shift block 14 to the left to drive its right side out of the limiting groove 18, and at the same time squeeze the spring 17 on its left side, and let the spring 17 be compressed on the inner wall of the slide groove 5, then pull the placement block 3 upward to drive the connecting block 4 on its left side to slide along the inner wall of the plug-in groove 15, and gradually let the placement block 3 out of the mounting groove 16, then the placement block 3 can be maintained. After completion, the placement block 3 is reset and inserted into the inner wall of the mounting groove 16, and at the same time release the shift block 14, and use the elastic force of the spring 17 itself to push the right side of the shift block 14 to always insert it into the inner wall of the limiting groove 18, so that the placement block 3 and the support block 2 are installed together, and it is convenient for subsequent maintenance, thereby improving the use effect of the machine body 1.

[0034] When the steel sample of different length is replaced, the clamping plate 12 is pulled forward and backward respectively, and its bottom is slid along the inner wall of the movable groove 6, and its upper part is slid along the outer side of the two fixed rods 13. At this time, the two clamping rods 8 are pushed and squeezed between the clamping groove 7, and the clamping rod 8 is gradually retracted to the inner wall of the slide groove 2 9, and the two movable plates 11 are driven to squeeze the elastic member 10 therebetween. After the adjustment is completed, the elastic force of the elastic member 10 is used to drive the movable plate 11 to move, and drive the separated ends of the two clamping rods 8 to be inserted into the inner wall of the clamping groove 7 matched with it after adjustment, so as to fix the position of the clamping plate 12 after adjustment, and then the steel sample is directly placed on the top of the two placement blocks 3, and is restricted by the front and rear clamping plates 12, so that the slot on the left side is kept between the two support blocks 2, so as to facilitate the fixing of the front and rear positions of the steel sample to prevent it from being offset, thereby improving the accuracy of the test;

[0035] When it is necessary to maintain the placement block 3, first push the shift block 14 to the left to drive its right side out of the limiting groove 18, and at the same time squeeze the spring 17 on its left side, and let the spring 17 be compressed on the inner wall of the slide groove 5, then pull the placement block 3 upward to drive the connecting block 4 on its left side to slide along the inner wall of the plug-in groove 15, and gradually let the placement block 3 out of the mounting groove 16, then the placement block 3 can be maintained. After completion, the placement block 3 is reset and inserted into the inner wall of the mounting groove 16, and at the same time release the shift block 14, and use the elastic force of the spring 17 itself to push the right side of the shift block 14 to always insert it into the inner wall of the limiting groove 18, so that the placement block 3 and the support block 2 are installed together, and it is convenient for subsequent maintenance, thereby improving the use effect of the machine body 1.
