[0027] The fixing mechanism 3 includes a support frame 31 and a column 36. The two ends of the column 36 are provided with teeth 37. The bottom of the support frame 31 is hinged to a half gear 38. The end of the half gear 38 away from the column 36 is fixedly connected to a first plate 39. The teeth 37 mesh with the half gear 38. The bottom of the support frame 31 is hinged to a second plate 310. The two ends of the second plate 310 are both hinged to a third plate 311. The side end of the third plate 311 is hinged to the side end of the first plate 39. The bottom end of the third plate 311 is provided with a fixing block 312. The inside of the fixing block 312 is provided with a second sliding groove 313. The inside of the second sliding groove 313 is elastically connected to a fixing column 314 by a spring.
[0028] The overall effect of this embodiment is that the relevant components can improve the adaptability of the clamping and fixing device to samples of different specifications and shapes through mechanical transmission. During the clamping and fixing process, it can effectively clamp according to the specifications and shapes of the steel bars. This mechanical transmission method improves the versatility of the equipment, reduces costs and operational difficulty, and also improves test efficiency and the accuracy of results.
[0029] Examples, such as Figure 1-6 As shown, a connecting block 32 is fixedly connected to the side end of the support frame 31, an electric telescopic rod 33 is fixedly connected to the side end of the connecting block 32, a guide rod 34 is fixedly connected to the side end of the electric telescopic rod 33, a first sliding groove 35 is provided on the side end of the support frame 31, and the guide rod 34 is slidably connected inside the first sliding groove 35. The protective mechanism 4 includes a transparent protective cover 41, a buffer assembly 42 is assembled inside the transparent protective cover 41, the buffer assembly 42 includes a hollow column 421, a hollow groove 422 is provided inside the hollow column 421, a friction wheel 423 is elastically connected inside the hollow groove 422 by a spring, and a connecting column 424 is elastically connected inside the hollow column 421 by a spring. An upper buffer plate 43 is fixedly connected to the side end of the connecting column 424. A first slider 44 is fixedly connected to the side end of the upper buffer plate 43. A third groove 45 is opened inside the transparent protective cover 41. The first slider 44 is slidably connected inside the third groove 45. A side buffer plate 46 is fixedly connected to the side end of the connecting column 424. A second slider 47 is fixedly connected to the side end of the side buffer plate 46. A fourth groove 48 is opened inside the transparent protective cover 41. The second slider 47 is slidably connected inside the fourth groove 48. An inlet 49 is opened on the side end of both the side buffer plate 46 and the transparent protective cover 41. The extended end of the electric telescopic rod 33 is fixedly connected to the top of the column 36.
[0030] The overall effect of this embodiment is as follows: when the electric telescopic rod 33 is activated, the guide rod 34 slides inside the first slide groove 35, so that the teeth 37 mesh with the half gear 38. When the sample breaks or fails, it flies out and squeezes the upper buffer plate 43 and the side buffer plate 46. The friction wheel 423 rolls on the outer wall of the connecting column 424, which can effectively prevent the sample from flying out when it breaks or fails. When the broken sample flies out, it buffers and decelerates it to avoid fragments from injuring the operator and other equipment.
[0031] The working principle of the entire equipment is as follows: Equipment inspection phase: Before starting to fix the steel bars, ensure that all parts are in normal working condition.
[0032] Fixing Stage: The reinforcing bar is inserted through inlet 49. At this time, the extension and retraction of the electric telescopic rod 33 is adjusted according to the size of the steel. When the steel is thick, the operator starts the electric telescopic rod 33, which drives the guide rod 34 to slide inside the first slide groove 35. At this time, due to the downward movement of the electric telescopic rod 33, the column 36 slides inside the support frame 31. At the same time, the tooth 37 meshes with the half gear 38, and the half gear 38 drives the first plate 39 to hinge and rotate away from the column 36 at the bottom of the support frame 31. Simultaneously, due to the hinge of the first plate 39, the second plate 310 hinges and rotates synchronously at the bottom of the support frame 31, so that the fixing block 312 is adaptively adjusted according to the size of the steel. When the external shape of the steel is uneven, the fixing column 314 is adapted to fit the rough parts of the steel.
[0033] Test phase: When the debris flies out, the debris squeezes the upper buffer plate 43 and the side buffer plate 46. At this time, the connecting column 424 slides elastically inside the empty column 421. At the same time, the friction wheel 423 rotates on the outer wall of the connecting column 424 while sliding on the connecting column 424.
[0034] Real-time monitoring: Staff should closely monitor changes in various indicators during the test and take timely measures if any abnormalities are found.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
