Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection, in particular to a tensile force detection device for engineering materials. Background Art

[0002] Before using engineering materials, they need to be tested for compressive strength to prevent the materials from having low compressive strength after use, which will affect the overall strength of the building.

The raw material tensile force detection device for engineering inspection includes a clamping assembly, which includes a clamping seat and a driving member; the driving member is connected to the clamping seat; at least two clamping heads are slidably provided on the clamping seat, and the clamping head has a clamping surface; the clamping seat has a clamping position, and two limit members are penetrated on the clamping seat, and the two limit members are respectively located on both sides of the clamping position. A clamping head matching the material to be tested is selected and slid to the clamping position, and then the limit member is penetrated into the clamping seat to prevent the clamping head from deviating from the clamping position. At this time, the driving member drives the two clamping seats to move closer to each other, and the clamping heads on the two clamping seats can be used to clamp and fix the material to be tested. When the material to be tested changes, it is only necessary to remove the limit member and then slide and adjust the position of the clamping head, without disassembling the entire clamping assembly. It is convenient and fast, and has a wide range of applications. However, the patent still has the following problems in actual use:

Figure 1-Figure 4 As shown, by setting a guiding bevel block 12 and a pushing bevel block 13, and by inserting a positioning screw 15 into the socket 14 in the middle of the pushing bevel block 13, by pulling the positioning screw 15, the positioning screw 15 drives the pushing bevel block 13 to move, so that the pushing bevel block 13 pushes the guiding bevel block 12, and the clamping rod 9 is contracted toward the middle, which is convenient for enhancing the clamping force when the test material is deformed and contracted, thereby achieving the effect of improving the clamping stability, and by setting the positioning nut 16, it is convenient to adjust the gap of the pushing bevel block 13, so that the applicability of the tension detection device is stronger, and thus the practicality of the engineering material tension detection device is stronger.

In the stretching process, the middle of the detection material is deformed first, so that the clamping rod 9 becomes loose. The threaded barrel 19 clamped at the end of the detection material will drive the movement of the positioning screw 15 to adjust the position of the pushing bevel block 13, so as to achieve the effect of clamping the clamping rod 9 on the outside of the detection material again, so that the stability of the tension detection device is stronger when used, thereby making the engineering material tension detection device more practical.

[0032] Working principle: When using the engineering material tensile testing device, first select a threaded barrel 19 with a suitable contraction groove 21 gap or a suitable inner diameter according to the size of the material to be tested, and insert the threaded barrel 19 into the outer side of the positioning screw 15 through the groove in the middle of the connecting screw 17, and lock the position of the threaded barrel 19 by connecting the connecting nut 18 to the connecting screw 17.

[0034] Finally, the control panel 2 is used to control the sliding frame 4 at the upper end of the tension detection equipment 1 to slide in the tension groove 3 toward the side away from the fixed frame 24. When the tension increases, the threaded tube 19 drives the inclined block 13 to slide on the guide inclined block 12 through the positioning screw 15, so that the clamping rod 9 contracts toward the middle, thereby achieving the effect of enhancing the clamping force.
