Description

Technical Field

[0001] The utility model relates to the technical field of raw material tension detection devices for engineering inspection, in particular to a raw material tension detection device for engineering inspection. Background Art

[0002] Tensile testing should be supplemented by burst testing. This type of tensile testing ensures the quality of the seal and is a mandatory test method. It can be divided into static tensile testing and dynamic tensile testing. Engineering materials are divided into four categories based on their chemical composition: metallic materials, non-metallic materials, polymer materials, and composite materials. As we all know, engineering materials need to be tested before use to prevent the overall strength of the building from being affected by substandard quality after use. There are many material testing items, among which tensile testing devices are used when conducting tensile testing on materials.

[0003] A tensile force detection device for raw materials used in engineering testing disclosed in the Chinese utility model patent application disclosure CN220322949U solves the problem of poor usability, but still has the following disadvantages: First, during the tensile force test, since the raw materials being tested are different, the raw materials may be broken during the test, thereby splashing and causing harm to the tester; Second, during the tensile force test, since the inserted testing rod is usually cylindrical or quadrangular prism-shaped, when the tension is large, the testing rod will slide, resulting in deviations in the tensile force test data.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] See also Figures 1 to 5The utility model provides a technical solution: a raw material tension detection device for engineering inspection, including a base 1, the top of the base 1 is fixedly connected to a first connecting plate 2, the top of the first connecting plate 2 is fixedly connected to a second connecting plate 3, the bottom of the second connecting plate 3 and the top of the base 1 are fixedly connected to a fixing seat 7, the fixing seat 7 is symmetrically distributed on the second connecting plate 3, and the two opposite side walls of the fixing seats 7 are provided with a first groove 8, the inner wall of the first groove 8 is rotatably connected to a first threaded rod 9, the outer end of the first threaded rod 9 is threadedly connected to a first slider 11, there are two first sliders 11, the bottom of the first slider 11 is fixedly connected to a first fixing plate 12, the right side wall of the left first fixing plate 12 is fixedly connected to a first fixing rod 13, and the left side wall of the right first fixing plate 12 is fixedly connected to a second fixing rod 14, there are two first connecting plates 2, and the first connecting plates 2 are symmetrically distributed on the base 1. The seat 7 is located at the center of the base 1 and the second connecting plate 3, the first groove 8 is T-shaped, the first threaded rod 9 is a bidirectional threaded rod, the first slider 11 is L-shaped, and the first slider 11 is symmetrically distributed on the first threaded rod 9. The first fixing plate 12 is square, the first fixing rod 13 is annular, and the second fixing rod 14 is cylindrical. The diameter of the second fixing rod 14 is consistent with the minor diameter of the first fixing rod 13, and the center of the first fixing rod 13 and the second fixing rod 14 are consistent. The first fixing rod 13 passes through the engineering test material, and the outer ends of the first fixing rod 13 and the second fixing rod 14 are provided with a pad 15, which is fixedly connected to the inner wall of the first fixing plate 12. A through hole is opened in the middle of the pad 15, and the diameter of the through hole is consistent with the major diameter of the first fixing rod 13. The material of the pad 15 is rubber, and the right side wall of the fixed seat 7 is fixedly installed with the first motor 10, and the first motor 10 is transmission connected to the first threaded rod 9.

[0026] During use, when conducting a tensile test, due to the different raw materials being tested, the raw materials may be broken during the test, thereby splashing and causing harm to the tester. Therefore, there is a tensile testing device for raw materials used in engineering testing. When the engineering raw materials need to be tensile tested, the first motor 10 is first started to rotate the first threaded rod 9, and the first slider 11 drives the first fixed rod 13 and the second fixed rod 14 to move to the left and right sides. The first fixed rod 13 is separated from the second fixed rod 14. At this time, the first fixed rod 13 penetrates the raw materials for testing, and then the first motor 10 is reversed to make the first slider 11 drive the second fixed rod 14 to move to the left and right sides. The first fixing rod 13 and the second fixing rod 14 move toward the middle, and the second fixing rod 14 is slowly inserted into the first fixing rod 13. Through the coordinated setting of the first fixing rod 13 and the second fixing rod 14, the test raw material will not fall off due to excessive tension during the test and separate from the clamping device. When the left and right sides of the raw material are in close contact with the pad 15, the movement of the first slider 11 is stopped. Through the setting that the material of the pad 15 is rubber, the raw material tension detection device for engineering inspection can increase the friction between the raw material and the clamping device, and at the same time prevent the raw material from being damaged by the strong clamping force.
