Description

Technical Field

[0001] This utility model relates to the technical field of insulation board compression testing device, and in particular to an anti-eccentric load device for insulation board compression testing. Background Technology

[0002] As a key material in building energy conservation and cold chain transportation, the mechanical properties of insulation boards (especially compressive strength and deformation characteristics) are core indicators for evaluating product quality and applicability. To ensure that insulation boards can withstand loads such as compression and stacking in practical applications, compression tests are needed to simulate their stress state. Existing insulation board compression testing devices are inconvenient to stably guide the pressure plate during use, causing the pressure plate to shift during the compression test of the insulation board, resulting in uneven pressure distribution and off-center loading. Utility Model Content

[0003] The purpose of this invention is to provide an anti-eccentric load device for the compression test of insulation boards, so as to solve the defect of existing insulation board compression test devices that are inconvenient to stably guide the pressure plate.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for preventing off-center loading during the compression test of a thermal insulation board, including a base; A pressing mechanism is fixedly connected to the top of the base; The pressing mechanism includes a U-shaped frame plate fixedly installed on the top of the base. A guide cylinder is fixedly connected to the top of the U-shaped frame plate, and a hydraulic rod is fixedly connected to the top of the U-shaped frame plate. A pressure plate is fixedly connected to the output end of the hydraulic rod, and a guide rod is fixedly connected to the top of the pressure plate. A U-shaped bracket is fixedly connected to one side of the pressure plate, and a rotating shaft is movably connected inside the U-shaped bracket. A roller is fixedly connected to the outer wall of the rotating shaft.

[0005] Preferably, an L-shaped plate is fixedly connected to the outer wall of the U-shaped frame plate, and a guide groove is provided inside the L-shaped plate.

[0006] Preferably, the guide rod and the guide cylinder form a sliding structure, and the guide rod is symmetrically arranged about the central axis of the pressure plate, so that the guide rod can slide along the guide cylinder.

[0007] Preferably, the U-shaped bracket forms a rotating structure with the roller via a rotating shaft, and the roller forms a sliding structure with the L-shaped plate via a guide groove, which allows the roller to rotate along the U-shaped bracket.

[0008] Preferably, the base has a limiting groove inside, the outer wall of the pressure plate is equipped with a feeding mechanism, the feeding mechanism includes a movable rod fixedly installed on the outer wall of the pressure plate, a guide plate is movably connected inside the movable rod, the guide plate has a movable groove inside, a platform is fixedly connected to the outer wall of the guide plate, and a limiting slide is fixedly connected to the bottom of the platform.

[0009] Preferably, the movable rod forms a sliding structure with the guide plate through the movable groove, and the limiting slide plate is symmetrically arranged with respect to the central axis of the platform, so that the movable rod can slide along the movable groove.

[0010] Preferably, the limiting slide plate forms a sliding structure with the base through the limiting slide groove, and the limiting slide plate is L-shaped, which allows the limiting slide plate to slide along the limiting slide groove.

[0011] The present invention provides a device for preventing off-center loading during the compression test of insulation boards, which has the following advantages: By setting up a pressing mechanism and activating the hydraulic rod, the pressure plate can be moved downward, allowing the guide rod to slide along the guide cylinder, so that the pressure plate can be pressed down smoothly. This can prevent the pressure plate from generating an off-center load when pressing down on the insulation board, thereby improving the stability of the compression test on the insulation board. Furthermore, since the outer wall of the roller is in contact with the inner wall of the guide groove, as the pressure plate moves down, the roller can rotate along the U-shaped bracket, further improving the stability of the pressure plate pressing down. With the base, pressure plate and feeding mechanism set up, the pressure plate presses down and drives the movable rod to move down, so that the movable rod slides along the movable groove, and drives the platform to slide along the base, so as to facilitate the stable feeding of the insulation board on the platform. Furthermore, when the pressure plate rises, the movable rod slides along the movable groove, causing the storage platform to slide along the base to discharge the material; Furthermore, the combined effect of the limiting slide plate and the limiting slide groove can improve the stability of the sliding of the shelf.

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.

[0015] Please see Figures 1-5 The present invention provides a device for preventing off-center loading during compression testing of insulation boards, comprising a base 1.

[0016] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pressing mechanism 2 is fixedly connected to the top of the base 1. The pressing mechanism 2 includes a U-shaped frame plate 21 fixedly installed on the top of the base 1. A guide cylinder 22 is fixedly connected to the top of the U-shaped frame plate 21. A hydraulic rod 23 is fixedly connected to the top of the U-shaped frame plate 21. A pressure plate 24 is fixedly connected to the output end of the hydraulic rod 23. A guide rod 25 is fixedly connected to the top of the pressure plate 24. A U-shaped bracket 26 is fixedly connected to one side of the pressure plate 24. A rotating shaft 27 is movably connected inside the U-shaped bracket 26. A roller 28 is fixedly connected to the outer wall of the rotating shaft 27. An L-shaped plate 3 is fixedly connected to the outer wall of the U-shaped frame plate 21. A guide groove 4 is opened inside the L-shaped plate 3. The guide rod 25 and the guide cylinder 22 form a sliding structure. The guide rod 25 is symmetrically arranged about the central axis of the pressure plate 24. The U-shaped bracket 26 forms a rotating structure with the roller 28 through the rotating shaft 27. The roller 28 forms a sliding structure with the L-shaped plate 3 through the guide groove 4.

[0017] By activating the hydraulic rod 23, the pressure plate 24 can be moved downward, causing the guide rod 25 to slide along the guide cylinder 22, allowing the pressure plate 24 to press down smoothly. Since the outer wall of the roller 28 is in contact with the inner wall of the guide groove 4, as the pressure plate 24 moves downward, under the action of the rotating shaft 27, the roller 28 can rotate along the U-shaped bracket 26, allowing the pressure plate 24 to perform a stable pressing test on the insulation board.

[0018] Reference Figure 1 , Figure 3 and Figure 5As shown, a limiting groove 5 is provided inside the base 1, and a feeding mechanism 6 is installed on the outer wall of the pressure plate 24. The feeding mechanism 6 includes a movable rod 61 fixedly installed on the outer wall of the pressure plate 24. A guide plate 62 is movably connected inside the movable rod 61. A movable groove 63 is provided inside the guide plate 62. A platform 64 is fixedly connected to the outer wall of the guide plate 62. A limiting slide plate 65 is fixedly connected to the bottom of the platform 64. The movable rod 61 and the guide plate 62 form a sliding structure through the movable groove 63. The limiting slide plate 65 is symmetrically arranged about the central axis of the platform 64. The limiting slide plate 65 and the base 1 form a sliding structure through the limiting groove 5. The limiting slide plate 65 is L-shaped.

[0019] By placing the insulation board on the platform 64, as the pressure plate 24 presses down, the movable rod 61 moves downward, causing the movable rod 61 to slide along the movable groove 63, which in turn causes the platform 64 to slide along the base 1. This allows the limiting slide plate 65 to slide along the limiting groove 5. When the platform 64 moves to a position parallel to the pressure plate 24, the movable rod 61 can slide downward along the turning point of the movable groove 63, allowing the insulation board on the platform 64 to be loaded.
