Description

Technical Field

[0001] This utility model relates to the field of insulation board testing technology, specifically to a device for testing the compressive strength of insulation boards. Background Technology

[0002] Insulation boards are made of polystyrene resin as the raw material, along with other raw materials and polymers. They are plastic boards with moisture-proof and waterproof properties, which can reduce the thickness of the building's external protective structure, thereby increasing the usable indoor area.

[0003] Compressive strength is an important indicator of thermal insulation boards. The compressive strength test involves placing the sample on a work platform and using a hydraulic press to apply pressure to the sample to test its ability to withstand pressure. However, existing compressive strength testing devices can only fix thermal insulation board samples of a specific size. When testing thermal insulation boards of different sizes, different testing devices need to be used, resulting in low applicability. Therefore, we propose a thermal insulation board compressive strength testing device to solve the above problems. Utility Model Content

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.

[0019] Example 1

[0020] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a compressive strength testing device for insulation boards, including a workbench 1. The top two ends of the workbench 1 are respectively fixedly connected to the two ends of the support 2. A hydraulic cylinder 3 is fixedly installed in the middle of the top of the support 2. The output shaft of the hydraulic cylinder 3 slides through the support 2 and is fixedly connected to the rear end of the support 2. The bottom of the pressure sensor 4 is provided with an adjustment component 7 that is rotatably connected to the top surface of the workbench 1. The bottom of both sides of the adjustment component 7 is respectively fixedly connected to the sliders of the slide rails 8. The slide rails 8 are respectively fixedly installed on the top surface of the workbench 1. One end of the adjustment component 7 is hinged to one end of the electric telescopic rod 6, and the other end of the electric telescopic rod 6 is fixedly connected to the support 2.

[0021] The top two sides of the adjusting component 7 are fixedly connected to the middle of the bottom of the support base 9, and the two ends of the support base 9 are slidably sleeved with support rods 10.

[0022] Example 2

[0023] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a controller 5 is fixedly installed on one side of the top of the workbench 1. The controller 5 is connected to the electric telescopic rod 6 and the pressure sensor 4 respectively. The controller 5 consists of an IPC3 type electric telescopic rod controller and an SPMK251-07 type intelligent pressure controller, which are used to control the electric telescopic rod 6 and receive and analyze the pressure signal of the pressure sensor 4, respectively. The hydraulic cylinder 3 can be a common hydraulic cylinder in the prior art that can realize the telescopic function. The specific model will not be described in this application.

[0024] Specifically, the support base 9 has an L-shaped structure and is symmetrically located on both sides of the top of the workbench 1. The two ends of the insulation board are respectively inserted into the support base 9, and the support base 9 supports the two ends of the insulation board.

[0025] Specifically, connecting seats 91 are fixedly connected to both ends of the support base 9, and support rods 10 are slidably sleeved in the connecting seats 91. Anti-detachment blocks 101 are fixedly connected to both ends of the support rods 10. The support rods 10 slide in the connecting seats 91, and the length direction of the support rods 10 is perpendicular to the length direction of the support base 9, so that the support base 9 and the support rods 10 form a U-shaped structure to support the four sides of the center of the insulation board. The anti-detachment blocks 101 are set to prevent the support rods 10 from detaching from the connecting seats 91.

[0026] Specifically, the drive end of the electric telescopic pole 6 is fixedly connected to a hinge seat 61.

[0027] Specifically, the adjustment assembly 7 includes an active column 71, an active connecting rod 72, a transmission plate 73, a support shaft 74, a driven connecting rod 75, and a driven column 76. One side of the active column 71 is fixedly connected to a hinge seat 61, and the other end of the active column 71 is fixedly connected to a slider of a slide rail 8. The middle of the active column 71 is hinged to one end of the active connecting rod 72, and the other end of the active connecting rod 72 is hinged to one end of the transmission plate 73. The middle of the transmission plate 73 is fixedly connected to one end of the support shaft 74, and the other end of the support shaft 74 is rotatably connected to the top of the worktable 1. The other end of the transmission plate 73 is hinged to one end of the driven connecting rod 75, and the other end of the driven connecting rod 75 is hinged to the middle of the driven column 76. One end of the driven column 76 is fixedly connected to a slider of another slide rail 8.

[0028] When the electric telescopic rod 6 is energized, it drives the adjustment assembly 7. The active column 71 of the adjustment assembly 7 moves linearly on a slide rail 8. The active column 71 drives the hinged active connecting rod 72 to move. The active connecting rod 72 drives the end-hinged transmission plate 73 to swing. The transmission plate 73 swings around the support shaft 74. The transmission plate 73 then drives the hinged driven connecting rod 75 to move. The driven connecting rod 75 drives the end-hinged driven column 76 to move linearly on another slide rail 8. The active column 71 and the driven column 76 then drive the top-fixed support seat 9 to move closer or further away from each other, thereby changing the distance between the two support seats 9. This facilitates the support and fixation of insulation boards of different sizes, increasing the applicability of this application.

[0029] Furthermore, the top ends of the active column 71 and the driven column 76 are respectively fixedly connected to the bottom middle of the support base 9, and the active connecting rod 72 and the driven connecting rod 75 are arranged parallel to each other.

[0030] During testing, the electric telescopic rod 6 is energized according to the required insulation board size. The electric telescopic rod 6 drives the adjusting component 7. The active column 71 of the adjusting component 7 moves linearly on a slide rail 8. The active column 71 drives the hinged active connecting rod 72 to move. The active connecting rod 72 drives the end-hinged transmission plate 73 to swing. The transmission plate 73 swings around the support shaft 74, which in turn drives the hinged driven connecting rod 75 to move. The driven connecting rod 75 drives the end-hinged driven column 76 to move linearly on another slide rail 8. The active column 71 and the driven column 76 then drive the top-fixed support seats 9 to move closer or further apart, thereby changing the distance between the two support seats 9. This facilitates support and fixation for insulation boards of different sizes, increasing the applicability of this application. After adjusting the spacing to the size of the insulation board to be tested, the two ends of the insulation board are respectively placed into the support base 9. The support base 9 supports the two ends of the insulation board. At the same time, when the spacing of the support base 9 is adjusted, the support rod 10 slides in the connecting seat 91. The length direction of the support rod 10 is set perpendicular to the length direction of the support base 9, so that the support base 9 and the support rod 10 form a U-shaped structure, which supports the four sides of the center of the insulation board. Finally, the hydraulic cylinder 3 works, and the hydraulic cylinder 3 drives the pressure sensor 4 installed at the end to descend. The pressure sensor 4 is used in conjunction with the SPMK251-07 intelligent pressure controller. Then, the hydraulic cylinder 3 and the pressure sensor 4 apply downward pressure to the insulation board. The pressure value is displayed and viewed through the SPMK251-07 intelligent pressure controller, realizing the compressive strength test of the insulation board.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
