DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0020] A device for testing the compression performance of thermal insulation materials, such as Figure 1 and Figure 2 As shown, it includes a base 1, a pressurizing component 2 and a controller 3. The pressurizing component 2 is provided on the left side of the top surface of the base 1, and the controller 3 is provided on the right side of the pressurizing component 2. The controller 3 includes a display 301, a keyboard 302 and a mouse 303. The display 301 is installed obliquely on the front of the controller 3. A host is provided in the controller 3. The keyboard 302 and the mouse 303 are placed on the base 1. The pressurizing pressure and the pressurizing time are set by the controller 3, and the signal received by the sensor is processed to form a chart and output.

[0021] like Figure 2 , Figures 6 to 12As shown, a mounting groove 101 is provided on the top surface of the base 1, and a self-centering component 4 is provided in the mounting groove 101. The self-centering component 4 includes a supporting column 401, a mounting cover plate 402 and a storage round table 403. The supporting column 401 is fixedly installed at the center of the bottom surface of the mounting groove 101, and a mounting cover plate 402 is fixedly installed on the top surface of the supporting column 401. The supporting column 401 supports the mounting cover plate 402 and the storage round table 403. Four T-shaped sliding grooves 404 are provided on the mounting cover plate 402, and a storage round table 403 is fixedly installed at the center position of the mounting cover plate 402. A cross transmission plate 405 is sleeved on the supporting column 401, and a seven-shaped transmission connecting rod 406 is rotatably installed at the four corners of the cross transmission plate 405. The seven-shaped connecting rod ensures that the cross transmission plate 405 can rotate when the mounting bottom plates on the left and right sides move toward the middle, so that the four centering components form a linkage to ensure that the detection material is in a circular The center of the platform, the transmission connecting rod 406 is fixedly installed with a mounting base plate 407, and the four mounting base plates 407 are fixedly installed with a T-shaped slider 408 arranged in cooperation with the T-shaped slide groove 404. The T-shaped slider 408 is slidably installed in the T-shaped slide groove 404, and the four T-shaped sliders 408 are fixedly installed with a centering block assembly 5, and the centering block assembly 5 includes a mounting block 501, a first force sensor 502 and an arc-shaped centering block 503. The mounting block 501 is fixedly installed on the top surface of the T-shaped slider 408, and the first force sensor 502 is fixedly installed on the side of the mounting block 501 close to the object placement circular table 403. The sensing end of the first force sensor 502 is fixedly installed with an arc-shaped centering block 503. When the T-shaped slider 408 slides toward the object placement circular table 403, the arc-shaped centering block 503 contacts and pushes the material to be detected. When the four first force sensors 502 are subjected to the same force, it means that the material is located at the center of the object placement circular table 403.

[0022] like Figures 8 to 10 As shown, a connecting frame 410 is fixedly installed on the bottom surface of the left mounting base plate 407 and the right mounting base plate 407, and a connecting rod 411 is sleeved on the lower end of the connecting frame 410. Two electric push rods 6 are arranged under the cross transmission disk 405. The working principle of the electric push rod is based on the cooperation of the motor and the lead screw. The core is to convert the rotational motion of the motor into linear motion. By changing the direction of the motor, the advancement and withdrawal of the push rod are controlled to achieve different movement directions. Compared with the control of the pneumatic push rod, it is more flexible. The telescopic ends of the two electric push rods 6 are fixedly connected by the connecting rod 411, and the driving ends of the two electric push rods 6 are also fixedly connected by the connecting rod 411. When the two electric push rods 6 are retracted, the mounting base plates 407 on the left and right sides move toward the middle, and the cross transmission disk 405 is rotated by the seven-shaped transmission connecting rod 406, and then the front and rear mounting base plates 407 are driven to move toward the middle by the front and rear two seven-shaped transmission connecting rods 406, so as to realize the linkage self-centering of the four centering block assemblies 5.

[0023] like Figure 1 and Figure 2As shown, the pressurizing component 2 includes a limit slide bar 201, a pressurizing screw rod 202 and a lifting seat 203. The four limit slide bars 201 are fixedly installed on the base 1, and the two pressurizing screw rods 202 are rotatably installed on the base 1. The four limit slide bars 201 and the upper ends of the two pressurizing screw rods 202 are jointly fixedly installed with a fixed top plate 204, and a protective shell is fixedly installed on the fixed top plate 204. The protective shell protects the screw rods, slide bars, etc. to prevent the internal structure of the pressurizing component from being directly exposed to the outside world. The four limit slide bars 201 and the lower ends of the two pressurizing screw rods 202 are jointly fixedly installed with a fixed bottom plate 205. The two pressurizing screw rods 202 pass through the fixed bottom plate 205 and are fixedly installed with a transmission gear 206. The two transmission gears 206 are jointly meshed with a driving gear 207, and the driving gear 207 is fixedly installed on the output shaft of the motor.

[0024] like Figures 1 to 5 As shown, the four limit slide bars 201 and the two pressurizing screw rods 202 are sleeved with a lifting seat 203, and the two pressurizing screw rods 202 are sleeved with a gap adjustment nut 208. The gap adjustment nut 208 is used to adjust the lifting seat 208 to be horizontal, so that the pressure can act in the vertical direction when pressurizing, so that the pressure on the test material is vertically downward, thereby increasing the accuracy of performance testing. The two gap adjustment nuts 208 are bolted on the lifting seat 203. When calibrating the level of the lifting seat 203, it is only necessary to adjust the gap adjustment nut and the lifting seat 2 03, a compression test assembly 7 is provided at the center of the lifting seat 203, the compression test assembly 7 comprises a mounting rod 701, a second force sensor 702 and a compression block 703, the mounting rod 701 is fixedly mounted on the lifting seat 203, the second force sensor 702 is fixedly mounted on the lower end of the mounting rod 701, the compression block 703 is fixedly mounted on the sensing end of the second force sensor 702, the compression block 703 is arranged directly above the storage truncated table 403, and the second force sensor 702 is used to detect the pressure data of the thermal insulation material.

[0025] When the embodiment 1 is working, the heat insulating material to be tested is placed on the storage truncated table 403, the electric push rod 6 is started to shrink, and the installation base plates 407 on the left and right sides drive the T slider 408 to slide toward the center along the T-shaped slot 404, and the cross transmission plate 405 rotates through the seven-shaped transmission connecting rod 406 to make the front and rear installation base plates 407 also drive the T slider 408 to slide toward the center along the T-shaped slot 404, and the centering block assembly 5 installed on the T-shaped slider pushes the heat insulating material to be tested to the center of the storage truncated table 403. When the four first force sensors 502 are subjected to the same force, the heat insulating material to be tested is already located at the center of the storage truncated table 403. Start the electric push rod 6 to extend it and move the centering block assembly 5 away from the thermal insulation material to be tested; start the motor of the pressurizing assembly 5, and drive the two pressurizing screws 202 to rotate through the active gear 207 and the transmission gear 206. The lifting seat 203 moves downward under the drive of the screw to apply pressure to the thermal insulation material to be tested. The compression block 703 transmits the pressure on the thermal insulation material to the second force sensor and collects it in the controller 3. The controller 3 converts the test data into a chart and outputs it through the display 301. After the test is completed, the lifting seat 203 is raised, the tested heat-resistant material is removed, and the crushed slag is cleaned to prevent the slag from entering the equipment and damaging the equipment. Example 2

[0026] Embodiment 2 is based on embodiment 1, as Figures 7 to 11 As shown, a dustproof slide 409 is fixedly installed on one side of the T-shaped slider 408 close to the transmission connecting rod 406, and the dustproof slide 409 is slidably installed in the T-shaped slide groove 404. When installing the dustproof slide 409, the T-shaped slider 408 needs to be retreated to the outermost side, and then the dustproof slide 409 is installed in the T-shaped slide groove, and the dustproof slide 409 is fixedly connected to the T-shaped slider 408 so that the dustproof slide 409 can slide simultaneously with the T-shaped slider 408, and the top of the dustproof slide 409 is flush with the top surface of the installation cover 402. The dustproof slide 409 can prevent crushed slag from falling into the equipment through the T-shaped slide groove during material detection, so as to avoid damage to the equipment or reduce the detection accuracy.

[0027] When Example 2 is working, the T-shaped slider 409 slides along the T-shaped slide groove 404 toward the center of the table along with the T-shaped slider 408. The top of the dustproof slide 409 is flush with the top surface of the installation cover 402 and will not collide with the table. After the centering is completed, the T-shaped slider 409 slides along the T-shaped slide groove 404 along with the T-shaped slider 408 to a position away from the center of the table to close the T-shaped slide groove 404, so as to facilitate the cleaning of the crushed slag produced by material detection, and at the same time prevent the slag from falling into the equipment through the T-shaped slide groove 404 and causing damage to the equipment.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
