Description

Technical Field

[0002] Geogrids are a major geosynthetic material, possessing unique properties and functions compared to other geosynthetics. They are commonly used as reinforcement in reinforced soil structures or composite materials. Geogrids are classified into four main categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids, and polyester warp-knitted geogrids. A geogrid is a two-dimensional mesh or a three-dimensional mesh screen with a certain height, made of polymers such as polypropylene and polyvinyl chloride through thermoplasticizing or molding. When used in civil engineering, it is called a geogrid. Geogrids are widely used as an indispensable building material in highways, railways, municipal engineering, water conservancy projects, and industrial buildings in my country. Because they are commonly used as reinforcement in reinforced soil structures, they need to possess certain tensile strength. However, some geogrid tensile testing equipment cannot effectively fix the geogrid during operation; therefore, a geogrid tensile strength testing device based on a universal testing machine was designed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides the following technical solution: a geogrid tensile strength testing device based on a universal testing machine, comprising an operating table 1, a first lead screw 2 and a second lead screw 3 mounted on the upper side of the operating table 1, an upper support seat 5 mounted on the top of the first lead screw 2 and the second lead screw 3, a top plate 4 mounted on the top of the upper support seat 5, a driving lifting device installed inside the operating table 1, a third lead screw 6 mounted on one side inside the upper support seat 5, a fourth lead screw 7 mounted on the other side inside the upper support seat 5, a first driving clamping device mounted on one side of the third lead screw 6 and the fourth lead screw 7, and a top plate 4 mounted on the other side of the third lead screw 6 and the fourth lead screw 7. A first support plate 8 has a first fixing rod 9 mounted on its inner surface, and the first fixing rod 9 is arranged linearly. A first clamping plate 10 is mounted on the surface of the first fixing rod 9. A lower support seat 11 is mounted on the middle side of the first lead screw 2 and the second lead screw 3. A fifth lead screw 12 is mounted inside the lower support seat 11. A second driving clamping device is mounted on one side of the fifth lead screw 12 and the sixth lead screw 32. A second support plate 13 is mounted on the other side of the fifth lead screw 12 and the sixth lead screw 32. A second fixing rod 14 is mounted on the inner surface of the second support plate 13, and the second fixing rod 14 is arranged linearly. A second clamping plate 15 is mounted on the surface of the second fixing rod 14.

[0021] In this embodiment, by setting up LED explosion-proof lights 18, workers can more clearly observe the stretching of the geogrid.

[0022] In this embodiment: by setting up a curtain rod 19, a protective curtain is hung on the curtain rod 19 during work, so that the protective curtain protects the workers. When the LED explosion-proof light 18 is turned on, the light can be blocked by the protective curtain, which not only protects the workers' eyes, but also increases the brightness of the geogrid.

[0023] In this embodiment, by setting cabinet doors 20, staff can place their personal belongings.

[0024] The working principle and usage process of this utility model are as follows: After the utility model is installed, the second motor 34 is turned on, causing the fourth gear 35 to rotate. The rotation of the fourth gear 35 then drives the fifth gear 25 and the sixth gear 26 to rotate, thereby causing the third lead screw 6 and the fourth lead screw 7 to rotate. This causes the first support plate 8 to move inward. The first support plate 8 drives the first fixing rod 9, which in turn pushes the first clamping plate 10 closer inward. When the geogrid is clamped by the first clamping plate 10, the second motor 34 is turned off. The third motor 28 is then turned on, causing the seventh gear 29 to rotate. The rotation of the seventh gear 29 then drives the eighth gear 30 and the ninth gear 31 to rotate, thereby causing the fifth lead screw 12 and the sixth lead screw 32 to rotate. This causes the second support plate 13 to move inward, which in turn drives the second fixed rod 14 to push the second clamping plate 15 closer to the inward side. When the geogrid is clamped by the second clamping plate 15, the third motor 28 is turned off. Then, the LED explosion-proof light 18 is turned on, and the protective curtain is hung on the curtain rod 19. This allows the first motor 21 to be turned on, which drives the first gear 22 to rotate. After the first gear 22 rotates, it drives the third gear 24 and the fourth gear 25 to rotate, which in turn causes the first lead screw 2 and the second lead screw 3 to rotate. This adjusts the height of the lower support 11, allowing a clear observation of the geogrid's stretching. All electrical equipment in this device is powered by an external power source, and all motors in this device are connected and controlled by a PLC control system.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
