Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a protective cover for concrete specimens used in conjunction with a pressure testing machine. Background Technology

[0002] In the field of building materials testing, concrete, as one of the most commonly used building materials, requires rigorous performance testing. Concrete compression testing machines are key equipment for evaluating the compressive strength of concrete and are widely used in quality testing for various engineering projects, including construction, building materials, roads, and bridges. During concrete specimen compression testing, the specimen may suddenly rupture under pressure, generating high-energy fragments that can fly out. These fragments can cause serious bodily injury to operators, such as cuts, bruises, or even more severe trauma. They can also damage the compression testing machine and other surrounding testing equipment, leading to high maintenance costs and equipment downtime.

[0003] Traditional concrete specimen protection covers have revealed numerous shortcomings when facing such risks. Early protective covers mostly used simple rigid structures, such as those welded from ordinary steel. While they provided some protection, they were prone to deformation or even breakage under high-intensity impacts, failing to reliably ensure the safety of personnel and equipment. Moreover, their fixed dimensions made it difficult to adapt to concrete specimens of different sizes, limiting their application scenarios.

[0004] While some protective covers have been improved with technological advancements, such as by adding cushioning materials, their cushioning effect remains limited. Furthermore, once the protective layer is damaged, the overall protective performance drops significantly, and maintenance and replacement costs are high. In addition, the installation and fixing methods of traditional protective covers are cumbersome in actual operation, consuming a significant amount of time and energy for operators and affecting testing efficiency. Therefore, a concrete specimen protective cover for use with a pressure testing machine is proposed to address these issues. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 An embodiment of this utility model provides a concrete specimen protective cover for matching a pressure testing machine, including a support and fixing plate 1, which serves as the basic load-bearing structure of the protective cover, provides a platform for the installation and fixing of other components, and bears the pressure and external force generated during the testing of the entire protective cover and specimen. The support and fixing plate 1 is externally fixedly connected to a fixing mechanism 2, and the support and fixing plate 1 is externally slidably connected to a protective mechanism 3. The fixing mechanism 2 includes a drive component 21, which serves as the power source of the fixing mechanism 2, provides driving force for the fixing and adjustment of the protective cover, and realizes the adaptation and fixing of concrete specimens of different sizes. The drive component 21 is externally fixedly connected to a rotating connecting plate 23.

[0033] The rotating connecting plate 23 is externally fixedly connected to three connecting rotating columns 22, which convert the circular motion of the rotating connecting plate 23 into the swing of the connecting rotating rod 25, thereby pushing the connecting sliding plate 27 and the connecting fixing ring 24 to slide. The connecting rotating rod 25 is rotatably connected to the outside of the connecting rotating column 22, which serves as a transmission component, converting the swing of the connecting rotating column 22 into the linear sliding of the connecting sliding plate 27, thereby realizing the position adjustment of the connecting fixing ring 24. The connecting sliding plate 27 is rotatably connected to the outside of the connecting rotating rod 25, i.e., the end away from the connecting rotating column 22. The connecting fixing ring 24 is fixedly connected to the outside of the connecting sliding plate 27. The connecting fixing ring 24 is used to fix the concrete specimen protective cover. The connecting sliding plate 27 drives the connecting fixing ring 24 to slide along the supporting sliding column 26, thereby realizing adaptive fixing of protective covers of different sizes.

[0034] The connecting fixing ring 24 is externally slidably connected to the outside of the supporting fixing plate 1. The connecting sliding plate 27 is internally slidably connected to the supporting sliding column 26, which provides guidance and support for the sliding of the connecting sliding plate 27 and the connecting fixing ring 24, ensuring that the fixing process is stable and accurate and avoiding deviation. The bottom of the supporting sliding column 26 is fixedly connected to the outside of the supporting fixing plate 1. The connecting rotating rod 25 is externally rotatably connected to the outside of the supporting fixing plate 1.

[0035] The rotating connecting plate 23 is externally rotatably connected to the outside of the supporting fixing plate 1. The driving assembly 21 includes a rotating motor 211. The driving end of the rotating motor 211 is fixedly connected to a rotating connecting column 212. The outside of the rotating connecting column 212 is fixedly connected to the inside of the rotating connecting plate 23. The outside of the rotating motor 211 is fixedly connected to the bottom of the supporting fixing plate 1. The outside of the rotating connecting column 212 is rotatably connected to the inside of the supporting fixing plate 1.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The protective mechanism 3 includes a pressure-resistant layer 31, which directly bears the impact force generated when the concrete specimen breaks. It is the core impact-resistant structure of the protective cover, protecting the safety of operators and equipment. The pressure-resistant layer 31 is externally fixedly connected to a support layer 32, which provides structural support for the pressure-resistant layer 31, enhances the overall rigidity and stability of the protective cover, and prevents the pressure-resistant layer 31 from deforming or being damaged when subjected to impact. The support layer 32 is externally fixedly connected to a connecting protective layer 33, which further enhances the protective performance of the protective cover and also serves to connect the support layer 32 and the anti-scratch layer 34, improving the overall integrity of the protective cover.

[0037] A scratch-resistant layer 34 is fixedly connected to the outside of the protective layer 33 to protect the outer surface of the protective cover and prevent it from being scratched or damaged during daily use, handling or installation, thus maintaining the appearance and performance of the protective cover. Multiple support connecting columns 7 are fixedly connected to the top plate of the support fixing plate 1. A control support plate 8 is slidably connected to the outside of the support connecting columns 7. The support connecting columns 7 are used to connect the support fixing plate 1 and the control support plate 8, providing support and guidance for the control support plate 8. A support base 6 is fixedly connected to the bottom of the support fixing plate 1, serving as the bottom support structure of the protective cover and transferring the weight of the entire protective cover and the pressure generated during testing to the ground, ensuring the stability and safety of the protective cover. A control cabinet 5 is fixedly connected to the outside of the support fixing plate 1, and a control panel 4 is fixedly connected to the top of the control cabinet 5.

[0038] Working principle: When it is necessary to fix the protective cover, the operation of the rotating motor 211 drives the rotating connecting column 212 to rotate, which in turn drives the rotating connecting plate 23 and the three connecting rotating columns 22 to rotate, which in turn drives the rotating rod 25 to rotate, which in turn drives the sliding plate 27 and the connecting fixing ring 24 to slide. At the same time, the supporting sliding column 26 provides a support track for the sliding of the sliding plate 27 and the connecting fixing ring 24, thereby achieving the effect of fixing the protective cover. It can also fix protective covers of different sizes.

[0039] The pressure-resistant layer 31 is made of high-strength alloy or ceramic material, and the support layer 32 is made of fiber composite material or metal frame to provide support for the pressure-resistant layer 31 and disperse the impact force. The multi-layer buffer structure connecting the protective layer 33 further absorbs the residual energy and connects the support layer 32 and the anti-scratch layer 34, which is made of wear-resistant material to resist external scratches. The support connecting column 7 is vertically fixed to the support fixing plate 1 to provide guidance and support for the control support plate 8, and facilitates the adjustment of the height and installation of control elements. The support base 6 is designed with a large contact area.
