Technical Field

[0002] Fireproof materials refer to various materials that play an absolute role in modern fire prevention and are mostly used in construction. Commonly used fireproof materials include fireproof panels, fireproof doors, fireproof glass, fireproof coatings and fireproof bags.

[0003] Since the masterbatch of fireproof materials is generally in granular form, when testing the high-temperature resistance of fireproof materials, if the fireproof materials inside the detection chamber cannot be stirred in time and cannot be heated evenly, the high-temperature resistance of the detected fireproof materials will be biased and the data will be inaccurate, making the detection work meaningless. In the prior art, the fireproof materials are evenly heated by rotating the placement table on which the fireproof materials are placed, but the effect is not good. For example, the bottom of the fireproof material cannot be heated evenly, and the fireproof material will still be heated unevenly, resulting in deviations in the detection results, which is not conducive to accurately grasping the high-temperature resistance of the fireproof material. Therefore, it does not meet the existing needs. We have proposed a high-temperature resistance detection device for fireproof materials. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] This embodiment is intended to promote the solution of the problem that in the prior art, the fireproof material is heated evenly by rotating the placement table on which the fireproof material is placed, but the effect is not good. For example, the bottom of the fireproof material cannot be heated evenly, and the fireproof material may be heated unevenly, resulting in deviation in the test results, which is not conducive to accurately grasping the high temperature resistance of the fireproof material. Please refer to Figure 1-3 A high temperature resistant detection device for fireproof materials includes a detection box 1, wherein the detection box 1 is respectively provided with a detection inner cavity 7 and a detection outer cavity 17, wherein a pushing mechanism 6 is provided inside the detection outer cavity 17, wherein the pushing mechanism 6 includes a first turntable 63, a second turntable 64, an eccentric rod 62 and a movable rod 67, wherein the first turntable 63 and the second turntable 64 have the same specifications and dimensions, wherein the first turntable 63 and the second turntable 64 are rotatably connected inside the detection outer cavity 17, wherein the first turntable 63 is fixedly sleeved on the periphery of the connecting rod 66, wherein there is a gap between the first turntable 63 and the second turntable 64, wherein a connecting column 19 is fixedly connected to the outer side of the second turntable 64, wherein the other end of the connecting column 19 is rotatably connected to the inner wall of the detection box 1 through a rotating shaft, so as to provide support balance.

[0024] The arrangement of the first turntable 63 and the second turntable 64 is conducive to driving the eccentric rod 62 to perform circular motion. The inner side of the first turntable 63 is fixedly connected to the eccentric rod 62 at a position off the center, and the other end of the eccentric rod 62 is fixedly connected to the second turntable 64. The eccentric rod 62 is respectively vertical to the first turntable 63 and the second turntable 64. Through the arrangement of the position of the eccentric rod 62, when the first and second turntables 64 are driven to rotate by the driving motor 61, the eccentric rod 62 will perform horizontal back and forth motion, thereby achieving the stirring of the fireproof material.

[0025] A display operator 2 is fixedly connected to the periphery of the detection box 1, and an observation door 5 is rotatably connected to one side of the detection box 1. The display operator 2 here is a mature existing technology. A circular hole is opened on one side of the detection inner cavity 7, and a movable rod 67 is inserted into the detection inner cavity 7 through the circular hole. A support frame 18 is fixedly connected to the inside of the detection box 1, and the top of the support frame 18 is fixedly connected to the drive motor 61. The support frame 18 can support the drive motor 61. The movable rod 67 is slidably sleeved on the periphery of the eccentric rod 62. The movable rod 67 is rotatably connected to the eccentric rod 62 through a sliding sleeve 65, and one end of the movable rod 67 is fixedly connected to the outer side of the sliding sleeve 65. Through the sliding sleeve 65, the movable rod 67 can rotate on the eccentric rod 62.

[0026] The pushing mechanism 6 also includes a driving motor 61, a connecting rod 66, a sliding sleeve 65, a material rake 68 and a rotating shaft 69. The output end of the driving motor 61 is rotatably connected to the connecting rod 66, and the other end of the movable rod 67 is rotatably connected to the material rake 68 through the rotating shaft 69. Through the setting of the rotating shaft 69, as the eccentric rod 62 rotates and drives the movable rod 67 to move, the movable rod 67 will move up and down slightly. At this time, the rotating shaft 69 can prevent the material rake 68 from moving up and down slightly, and only move forward and backward in the horizontal direction. The several rakes inside the material rake 68 are staggered. Through the setting of the material rake 68, it is beneficial to flip the fireproof material back and forth, so that it is heated evenly, and the high temperature resistance of the fireproof material can be accurately grasped.

[0027] In this embodiment: firstly, the observation door 5 is opened to place the fireproof material to be tested on the placement table 9, then the temperature inside the inner cavity 7 is controlled by the display operation instrument 2, and then the driving motor 61 is started to drive the connecting rod 66 to rotate, and the rotation of the connecting rod 66 will drive the first and second turntables 64 and the eccentric rod 62 to rotate, and at this time, the movable rod 67 and the material rake 68 connected to the eccentric rod 62 will move back and forth in the horizontal direction, and finally the fireproof material is evenly heated.

[0028] Example 2

[0029] This embodiment is intended to solve the problem that when the fireproof material has been tested, the temperature of the fireproof material is too high, so the staff cannot take it out directly, and need to wait until the temperature of the fireproof material drops before taking it out. In this process, there will be a long waiting time, which greatly reduces the work efficiency. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3 , Figure 4, a placing table 9 is fixedly connected to the bottom of the inner cavity 7 for testing, and a connecting table 13 is rotatably connected to the center of the placing table 9. When the connecting table 13 is in a horizontal state, it is in the same plane with the placing table 9. A No. 1 rotating rod 8 is rotatably connected inside the connecting table 13, and the two ends of the No. 1 rotating rod 8 are rotatably connected to the two sides of the placing table 9 respectively. Through the No. 1 rotating rod 8, the connecting table 13 can be rotated to facilitate the later pouring of the fireproof material into the unloading box 4. A unloading box 4 is placed at the bottom of the outer cavity 17 for testing, and a guide plate 3 is fixedly connected to one side of the bottom of the placing table 9. The guide plate 3 can assist in the unloading of the fireproof material. A No. 2 rotating rod 10 is fixedly installed at the bottom of the outer cavity 17 for testing, and a push rod 12 is rotatably sleeved on the outer periphery of the No. 2 rotating rod 10, and the push rod 12 is L-shaped. A connecting piece is fixedly connected to the bottom of the connecting platform 13, and one end of the push rod 12 is rotatably connected to the connecting piece. When the push rod 12 moves upward, it will push the connecting platform 13 to do a tilting movement. The other end of the push rod 12 is fixedly connected to a telescopic rod 15. Through the telescopic rod 15, when the push rod 12 needs to be limited, the telescopic rod 15 will be contracted, and then the telescopic rod 15 will be limited by the limiting seats 16 on both sides, and finally the limiting of the push rod 12 is achieved. The limiting seats 16 are fixedly installed on both sides of the other end of the telescopic rod 15. Through holes 11 and a plurality of limiting grooves 14 are respectively opened on the periphery of the detection box 1. The telescopic rod 15 is inserted into the inside and outside of the detection box 1 through the through holes 11, and the limiting grooves 14 are connected with the through holes 11. The limiting grooves 14 and the limiting seats 16 are matched and used.

[0030] In this embodiment: when the fireproof material has been inspected, the telescopic rod 15 can be pressed downward, and then one end of the connecting rod 66 will move in the opposite (upward) direction as the telescopic rod 15 moves, and then one side of the connecting platform 13 will be lifted up by the upward movement of the connecting rod 66 and will be in an inclined state, so that the fireproof material can fall from the inclined connecting platform 13 into the lower material box 4.
