Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation material testing, specifically to a compressive strength testing device for thermal insulation materials. Background Technology
[0002] In industrial and construction applications, employing effective thermal insulation technologies and materials can often yield significant results with minimal effort. Thermal insulation materials generally refer to those with a thermal coefficient less than or equal to 0.12. These materials can collect excess heat, release it smoothly and timely, exhibit minimal heat gradient changes, effectively reduce heat loss, maintain a stable room temperature, and provide balanced insulation during winter. To ensure the quality of insulation materials before use, their compressive strength must be tested using a compressive strength testing device after production.
[0003] Chinese patent discloses a compressive strength testing device for thermal insulation materials (authorization announcement number CN222070353 U). This patented technology can solve the problem that it is inconvenient to observe the surface changes of thermal insulation materials under compressive conditions, thus preventing staff from recording in real time. However, the patent still has the following problems: In the strength testing process of the insulation material in this patent, the lack of external protective structure makes it easy for the fragments to cut workers if the insulation material breaks. In addition, the insulation material usually works in a high-temperature environment and has not been tested under different temperature conditions, resulting in a large error between the experimental results and the actual situation.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0013] Please see Figures 1-5 This embodiment provides a compressive strength testing device for thermal insulation materials, including a placement platform 1 and an outer cavity 2. A fixing groove is formed on the upper surface of the placement platform 1. A limit screw 11 is rotatably mounted on the left end face of the fixing groove via a bearing. A first motor 12 is mounted on the right end face of the limit screw 11. First sliders are symmetrically screwed to the outer walls of the limit screw 11. The outer cavity 2 is mounted on the upper surface of the first slider. A worktable 13 is mounted on the inner end of the outer cavity 2. A weighing module 14 is embedded on the upper surface of the worktable 13. A top frame 15 is mounted on the upper surface of the worktable 13. An adjusting cylinder 16 is installed on the surface, and a pressure head 17 is installed at the output end of the adjusting cylinder 16. The limiting screw 11 has symmetrical threads on the left and right sides with opposite directions. During operation, the insulation material is placed on the workbench 13, and then the first motor 12 is started, driving the limiting screw 11 to rotate, so that the outer cavity 2 moves inward to seal it, avoiding the insulation material from breaking during the pressing process, so that the fragments can be splashed onto the workers and cause scratches. The adjusting cylinder 16 is started, driving the pressure head 17 to move down, thereby pressing the surface of the insulation material. The degree of pressing is measured by the weighing module 14.
[0014] The workbench 13 has symmetrical side slots installed on its upper surface. A first screw 18 is rotatably installed on the inner end of the side slot via a bearing. An adjusting slider is screwed to the outer wall of the first screw 18. A limit plate 19 is installed on the upper surface of the adjusting slider. A handle 21 is installed on the outer end of the first screw 18. During operation, rotating the handle 21 causes the first screw 18 to rotate, thereby moving the limit plate 19 inward to clamp and fix the insulation material, preventing it from shifting position during the downward pressing and hammering process.
[0015] The handle 21 has a triangular groove on its outer end. The inner wall of the triangular groove is made of magnetic material. A triangular magnetic block 22 is installed on the inner end of the outer cavity 2. The triangular magnetic block 22 fits into the triangular groove. During operation, as the outer cavity 2 moves inward, the triangular magnet and the triangular groove attract and fix each other, thereby limiting the handle 21 and preventing it from rotating and causing the limiting plate 19 to loosen.
[0016] Multiple heating bars 23 are symmetrically installed on the inner sidewalls of the outer cavity 2. A temperature sensor 24 is installed on the top of the outer cavity 2. A control panel 25 is installed on the left end face of the placement platform 1. The heating bars 23 and the temperature sensor 24 are electrically connected to the control panel 25. During operation, a PLC program is written in the control panel 25 to control the operation of each device. The heating bars 23 heat the inside of the outer cavity 2. The temperature is adjusted by the control panel 25 to simulate the compressive strength of heat preservation at different temperatures, making the experimental data more accurate.
[0017] An adjusting screw 26 is screwed to the bottom of the placement platform 1. The adjusting screw 26 passes through the outer wall of the limiting screw 11. A connecting rod 27 is installed at the bottom of the adjusting screw 26. A sleeve 28 is arranged at the outer end of the connecting rod 27. A U-shaped frame 29 is installed at the bottom of the placement platform 1. The sleeve 28 is installed at the bottom of the U-shaped frame 29. During operation, the adjusting screw 26 limits and fixes the limiting screw 11 to further improve its stability. The sleeve 28 does not contact the connecting rod 27, mainly to prevent the adjusting screw 26 from loosening and falling off.
[0018] In the actual operation, the insulation material is placed on the workbench 13, and then the first motor 12 is started, which drives the limit screw 11 to rotate, so that the outer cavity 2 moves inward to seal it, so as to avoid the insulation material from breaking during the pressing process and thus the risk of fragments flying onto the workers and causing scratches. The regulating cylinder 16 is started, which drives the pressure head 17 to move down, thereby pressing the surface of the insulation material. The degree of pressing is measured by the weighing module 14.
[0019] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
