Description

Technical Field

[0001] The invention relates to the technical field of rock wool board detection equipment, in particular to a fly ash resource-based building material performance detection device. Background Art

[0002] Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. Using fly ash resources to make rock wool boards and increase the recycling rate of fly ash resources can effectively reduce the recycling production cost and reduce the pollution of fly ash to the environment.

[0003] As an environmentally friendly building material, rock wool board has excellent fire resistance, heat preservation, tensile strength and other characteristics. At present, the inspection of a batch of rock wool boards is carried out by sampling and sending them to the inspection agency for manual inspection. Not only is the inspection time long and inefficient, but there are also omissions in sampling inspection and the inspection results are accidental. Summary of the invention

[0004] The purpose of the present invention is to provide a fly ash resource-based building material performance detection device to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A fly ash resource-based building material performance detection device includes a base frame, a door frame, a bottom frame, a first motor, a conveyor belt, a positioning mechanism and a detection mechanism. The base frame is fixedly connected to the door frame and the bottom frame, the first motor is fixedly connected to the door frame, the conveyor belt is fixedly connected to the bottom frame, the output end of the first motor is transmission-connected to the conveyor belt, the positioning mechanism is fixedly connected to the bottom frame, and the detection mechanism is fixedly connected to the positioning mechanism.

[0006] The detection device is used to detect rock wool boards made of fly ash resources. The detection device can simultaneously detect whether the thermal insulation performance and the tensile stress strength perpendicular to the surface of the rock wool board are qualified. The first motor outputs torque to the conveyor belt, and the rock wool board made of fly ash is transported by the conveyor belt to the bottom of the positioning mechanism on the bottom frame. The positioning mechanism drives the detection mechanism to adjust its position in the two-dimensional coordinate plane. The positioning mechanism lowers the detection mechanism and makes it close to the upper surface of the rock wool board. The sampled rock wool board can be sampled and tested at multiple points, thereby improving the detection integrity of the overall thermal insulation performance and stress strength of a single sampled rock wool board, and there will be no situation where defects in some areas cannot be detected.

[0007] Furthermore, the positioning mechanism includes a first sliding bar, a reciprocating motor, a side frame, a second sliding bar, a frame and a transverse motor. The first sliding bar is fixedly connected to the bottom frame, the reciprocating motor is slidably connected to the first sliding bar, the side frame is fixedly connected to the reciprocating motor and the second sliding bar, the transverse motor is slidably connected to the second sliding bar, and the frame is fixedly connected to the transverse motor and the detection mechanism.

[0008] A clamping roller is arranged inside the reciprocating motor, which drives the reciprocating motor itself to slide along the first slide bar through the clamping roller, and drives the second slide bar to horizontally move along the axis direction of the first slide bar through the side frame assembled on the reciprocating motor, and drives the transverse motor to slide along the second slide bar through the clamping roller arranged inside the transverse motor. The frame is assembled on the transverse motor, and the frame moves laterally along the axis direction of the second slide bar. Through the cooperation between the reciprocating motor and the transverse motor, the detection mechanism assembled on the frame is adjusted in the horizontal two-dimensional coordinate plane of the surface of the rock wool board, and multi-point sampling detection is performed on the surface of the rock wool board.

[0009] Furthermore, the detection mechanism includes a pushing cylinder, a fixed frame, a top cylinder and a bottom cylinder. The pushing cylinder is fixedly connected to the frame, the output end of the pushing cylinder is rotatably connected to the top cylinder, the fixed frame is fixedly connected to the pushing cylinder and the bottom cylinder, the top cylinder is provided with air holes, first through holes and external threads, the air holes and the first through holes are provided with several groups, several groups of air holes are arranged on the circumference of the side wall of the top cylinder, several groups of first through holes are arranged on the circumference of the bottom of the bottom cylinder, the bottom cylinder is provided with internal threads, first annular grooves and second annular grooves, the first annular grooves and the second annular grooves are arranged on the side wall of the bottom cylinder away from the top cylinder, and the external threads are connected with the internal threads by threads.

[0010] The detection mechanism moves to the sampling point above the surface of the rock wool board, pushing the output end of the cylinder to push the top cylinder to move toward the bottom cylinder. Since the top cylinder and the bottom cylinder are threadedly connected through the external thread and the internal thread, the output end of the cylinder is pushed to rotate and assemble with the top cylinder. The top cylinder moves toward the bottom cylinder and rotates at the same time, and itself moves toward the bottom cylinder in a spiral shape.

[0011] Furthermore, the detection mechanism also includes a heating mechanism, a sealing mechanism and a temperature measuring mechanism. The heating mechanism is fixedly connected to the top tube and the first through hole, the sealing mechanism is fixedly connected to the bottom tube, the heating mechanism is slidably connected to the first annular groove and the second annular groove, the temperature measuring mechanism is fixedly connected to the fixed frame, and the temperature measuring mechanism is provided with several groups, and the several groups of temperature measuring mechanisms are evenly distributed along the circumference of the fixed frame.

[0012] The detection mechanism is lowered as a whole, the sealing mechanism and the temperature measuring mechanism at the bottom of the bottom cylinder contact the upper surface of the rock wool board, and the top cylinder drives the heating mechanism to rotate spirally toward the bottom cylinder. The heating mechanism heats the air in the space composed of the top cylinder, the bottom cylinder and the rock wool board, and the external temperature measuring mechanism detects the temperature change to judge the thermal insulation effect of the rock wool board and whether the heated air escapes. After completing the thermal insulation performance test, the heating mechanism burns out the air in the space composed of the top cylinder, the bottom cylinder and the rock wool board to generate negative pressure, so that the top cylinder and the bottom cylinder are pressed and adsorbed on the surface of the rock wool board, and the cylinder is pushed to pull the top cylinder and the bottom cylinder upward. When the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the internal valve port can be opened to complete the air pressure relief inside the top cylinder and separate the bottom cylinder from the rock wool board. When the strength of the rock wool board itself is insufficient, before the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the rock wool board will be damaged, making the top cylinder and the bottom cylinder unable to be adsorbed.

[0013] Furthermore, the heating mechanism includes a liner, a first gas cylinder, a pneumatic mechanism, a first spring, a first ring, a second ring and a heating gun. The liner is fixedly connected to the top cylinder and the first gas cylinder. The first gas cylinder is provided with a second through hole and a third through hole. The pneumatic mechanism is fixedly connected to the first through hole, the second through hole and the second ring. The first spring is fixedly connected to the liner and the first ring. The first ring is slidably connected to the first ring groove. The second ring is slidably connected to the second ring groove. The heating gun is fixedly connected to the second through hole.

[0014] The top cylinder drives the heating mechanism to rotate spirally toward the bottom cylinder. The liner and the first ring compress the first spring while the first ring slides along the first ring groove. The lower connecting rod and the cylinder shell squeeze the second spring. The cylinder shell drives the second ring to slide along the second ring groove. When testing the thermal insulation performance of the rock wool board, the heating gun heats the air in the space formed by the top cylinder, the bottom cylinder and the rock wool board to expand the air. At the same time, the sealing mechanism and the air pressure mechanism seal the space so that the expanded heated air can only flow out from the gap of the rock wool board. The sealing and thermal insulation effect of the rock wool board is tested by an external temperature measuring mechanism. When testing the stress strength of the rock wool board, the flame of the heating gun generates heat energy while burning out the air in the space formed by the top cylinder, the bottom cylinder and the rock wool board to generate negative pressure. At the same time, the heat energy generated by the flame of the heating gun is transmitted to the air pressure mechanism through the first air cylinder. The gas in the air pressure mechanism expands due to heat and continues to seal, so that the top cylinder and the bottom cylinder are pressed and adsorbed on the surface of the rock wool board. When the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the internal valve of the air pressure mechanism can be opened to complete the air pressure relief inside the top cylinder and separate the bottom cylinder from the rock wool board.

[0015] Furthermore, the pneumatic mechanism includes an outer cylinder, a one-way ball valve, a ring frame, a second air cylinder, an upper connecting rod, a lower connecting rod, a second spring and a cylinder shell. The outer cylinder is fixedly connected to the first through hole and the second through hole, the one-way ball valve is fixedly connected to the outer cylinder, the upper connecting rod and the lower connecting rod, the ring frame is fixedly connected to the outer cylinder and the second air cylinder, the upper connecting rod is slidably connected to the second air cylinder, the second spring is fixedly connected to the lower connecting rod and the cylinder shell, the lower connecting rod is slidably connected to the cylinder shell, the cylinder shell is fixedly connected to the second ring, and the upper connecting rod and the bottom of the second air cylinder form a sealed air cavity.

[0016] When testing the thermal insulation performance of the rock wool board, the heating gun heats the air in the space composed of the top cylinder, the bottom cylinder and the rock wool board to expand the air. The one-way gas flow direction of the one-way ball valve is from top to bottom, and the expanded heated air cannot leak out of the one-way ball valve. When testing the stress strength of the rock wool board, the air in the space composed of the top cylinder, the bottom cylinder and the rock wool board is burned out to generate negative pressure, and at the same time, the temperature-sensitive gas in the sealed air cavity composed of the upper connecting rod and the bottom of the second gas cylinder is heated, so that the temperature-sensitive gas expands and pushes the upper connecting rod upward, so that the upper connecting rod pulls the valve core seal of the one-way ball valve. When the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the top cylinder spirally rotates away from the bottom cylinder and presses against the top of the cylinder shell through the lower connecting rod. When the top of the cylinder shell continues to restrict the lower connecting rod, as the pushing cylinder continues to pull the outer cylinder away, the temperature-sensitive gas in the sealed air cavity composed of the upper connecting rod and the bottom of the second gas cylinder is reversely compressed, and the one-way ball valve opens, and the expanded air in the space composed of the top cylinder, the bottom cylinder and the rock wool board is leaked from the one-way ball valve.

[0017] Furthermore, the sealing mechanism includes an outer shell, a limiting spring, a limiting plate and a third spring. The outer shell is fixedly connected to the bottom tube and the limiting spring. The limiting spring is provided in several groups, and the several groups of limiting springs are linearly evenly distributed along the side wall of the outer shell. The limiting plate is in contact with the limiting spring, and the third spring is fixedly connected to the outer shell and the limiting plate.

[0018] The detection mechanism is lowered as a whole, and the limit plate contacts the upper surface of the rock wool board. As the detection mechanism continues to descend, the limit plate successively breaks through several linearly evenly distributed limit springs. Under the action of the third spring restoring the deformation, the limit plate presses against the upper surface of the rock wool board to complete the sealing.

[0019] Furthermore, the temperature measuring mechanism includes a bent rod, a sealing cover and a temperature sensor. The bent rod is fixedly connected to the fixing frame, and the sealing cover is fixedly connected to the bent rod and the temperature sensor.

[0020] The detection mechanism is lowered as a whole and connected to the sealing cover through the curved rod assembled on the fixed frame. The sealing cover contacts the upper surface of the rock wool board. The temperature sensor is used to detect the expanded and heated air flowing out of the gap of the rock wool board to judge the thermal insulation effect of the rock wool board. The thermal insulation effect of each area in different directions can be judged by several groups of temperature measuring mechanisms evenly distributed around the circumference of the fixed frame.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a detection mechanism, which can simultaneously detect whether the thermal insulation performance of the rock wool board and the tensile stress strength perpendicular to the surface are qualified, and can perform multi-point sampling detection on the sampled rock wool board, thereby improving the detection integrity of the overall thermal insulation performance and stress strength of a single sampled rock wool board, and there will be no situation where defects in some areas cannot be detected; the present invention designs a heating mechanism and an air pressure structure coordinated therewith, and when detecting the thermal insulation performance of the rock wool board, the heating gun heats the air in the space formed by the top tube, the bottom tube and the rock wool board to expand the air, and the gas flow direction of the one-way ball valve is from top to bottom. The expanded and heated air cannot leak from the one-way ball valve, but can only flow out from the gaps in the rock wool board, and the sealing and thermal insulation effect of the rock wool board is detected by an external temperature measuring mechanism; when detecting the stress strength of the rock wool board, the heating gun sprays flames to generate heat energy while the internal air burns out to produce Negative pressure heats the temperature-sensitive gas in the sealed air cavity, causing the temperature-sensitive gas to expand and push the upper connecting rod upward, pulling the valve core seal of the one-way ball valve. When the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the top cylinder spirally rotates away from the bottom cylinder, and the lower connecting rod presses against the top of the cylinder shell. As the pushing cylinder continues to pull the outer cylinder away, the temperature-sensitive gas in the sealed air cavity is reversely compressed, the one-way ball valve opens, and the expanded air in the internal space is discharged from the one-way ball valve, separating the bottom cylinder from the rock wool board. When the strength of the rock wool board itself is insufficient, before the pulling force continuously output by the pushing cylinder reaches the predetermined minimum stress strength standard of the rock wool board, the rock wool board will be damaged, making it impossible for the top cylinder and the bottom cylinder to adsorb the rock wool board. The present invention can automatically detect whether the thermal insulation performance of the rock wool board made of fly ash and the tensile stress strength perpendicular to the surface are qualified, and multi-point sampling detection improves the detection efficiency and avoids the situation of missing defects.

[0026] The detection device is used to detect the rock wool board made of fly ash resources. The detection device can simultaneously detect whether the thermal insulation performance and the tensile stress strength perpendicular to the surface of the rock wool board are qualified. The first motor 4 outputs torque to the conveyor belt 5, and the rock wool board made of fly ash is transported by the conveyor belt 5 to the bottom of the positioning mechanism 6 on the bottom frame 3. The positioning mechanism 6 drives the detection mechanism 7 to adjust its position in the two-dimensional coordinate plane. The positioning mechanism 6 lowers the detection mechanism 7 to fit the upper surface of the rock wool board. The sampled rock wool board can be sampled and tested at multiple points, thereby improving the detection integrity of the overall thermal insulation performance and stress strength of a single sampled rock wool board, and there will be no situation where defects in some areas cannot be detected.

[0027] like Figure 1 , Figure 2 As shown, the positioning mechanism 6 includes a first slide bar 61, a reciprocating motor 62, a side frame 63, a second slide bar 64, a frame 65 and a transverse motor 66.

[0028] A clamping roller is arranged inside the reciprocating motor 62, which drives the reciprocating motor 62 to slide along the first slide bar 61, and drives the second slide bar 64 to move horizontally along the axis direction of the first slide bar 61 through the side frame 63 assembled on the reciprocating motor 62, and drives the transverse motor 66 to slide along the second slide bar 64 through the clamping roller arranged inside the transverse motor 66.

Through the cooperation between the reciprocating motor 62 and the transverse motor 66, the detection mechanism 7 assembled on the frame 65 is adjusted in the horizontal two-dimensional coordinate plane of the surface of the rock wool board, and multi-point sampling detection is performed on the surface of the rock wool board.

[0029] like Figure 3 , Figure 4 As shown, the detection mechanism 7 includes a pushing cylinder 71, a fixing frame 72, a top cylinder 73 and a bottom cylinder 74. The pushing cylinder 71 is fixedly connected to the frame 65. The output end of the pushing cylinder 71 is rotatably connected to the top cylinder 73. The fixing frame 72 is fixedly connected to the pushing cylinder 71 and the bottom cylinder 74. The top cylinder 73 is provided with an air hole 731, a first through hole 732 and an external thread 733. The air holes 731 and the first through holes 732 are provided with several groups. Several groups of air holes 731 are arranged on the side wall of the top cylinder 73 and are evenly distributed around the circumference. Several groups of first through holes 732 are arranged on the bottom of the bottom cylinder 74 and are evenly distributed around the circumference. The bottom cylinder 74 is provided with an internal thread 741, a first annular groove 742 and a second annular groove 743. The first annular groove 742 and the second annular groove 743 are arranged on the side wall of the bottom cylinder 74 away from the top cylinder 73. The external thread 733 is connected to the internal thread 741 through threads.

[0030] The detection mechanism 7 moves to the sampling point above the surface of the rock wool board, pushing the output end of the cylinder 71 to push the top cylinder 73 to move toward the bottom cylinder 74. Since the top cylinder 73 and the bottom cylinder 74 are threadedly connected through the external thread 733 and the internal thread 741, the output end of the cylinder 71 is pushed to rotate and assemble with the top cylinder 73. The top cylinder 73 moves toward the bottom cylinder 74 and rotates at the same time, and itself moves toward the bottom cylinder 74 in a spiral shape.

[0031] like Figure 3 , Figure 4 As shown, the detection mechanism 7 also includes a heating mechanism 75, a sealing mechanism 76 and a temperature measuring mechanism 77. The heating mechanism 75 is fixedly connected to the top tube 73 and the first through hole 732. The sealing mechanism 76 is fixedly connected to the bottom tube 74. The heating mechanism 75 is slidably connected to the first annular groove 742 and the second annular groove 743. The temperature measuring mechanism 77 is fixedly connected to the fixed frame 72. The temperature measuring mechanism 77 is provided with a plurality of groups, and the plurality of groups of temperature measuring mechanisms 77 are evenly distributed along the circumference of the fixed frame 72.

[0032] The detection mechanism 7 is lowered as a whole, the sealing mechanism 76 and the temperature measuring mechanism 77 at the bottom of the bottom cylinder 74 contact the upper surface of the rock wool board, the top cylinder 73 drives the heating mechanism 75 to rotate spirally toward the bottom cylinder 74, the heating mechanism 75 heats the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board, and the external temperature measuring mechanism 77 detects the temperature change to judge the thermal insulation effect of the rock wool board and whether the heated air escapes; after completing the thermal insulation performance test, the heating mechanism 75 burns out the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board, generating a negative The top cylinder 73 and the bottom cylinder 74 are pressed and adsorbed on the surface of the rock wool board, and the air cylinder 71 is pushed to pull the top cylinder 73 and the bottom cylinder 74 upward. When the pulling force continuously output by the pushing cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, the internal valve port can be opened to complete the pressure relief of the air inside the top cylinder 73 and separate the bottom cylinder 74 from the rock wool board. When the strength of the rock wool board itself is insufficient, the rock wool board will be damaged before the pulling force continuously output by the pushing cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, making the top cylinder 73 and the bottom cylinder 74 unable to be adsorbed.

[0033] like Figure 4 , Figure 6As shown, the heating mechanism 75 includes a liner 751, a first gas cylinder 752, a pneumatic mechanism 753, a first spring 754, a first ring 755, a second ring 756 and a heating gun 757.

The pneumatic mechanism 753 is fixedly connected to the first through hole 732, the second through hole 7521 and the second ring 756. The first spring 754 is fixedly connected to the liner 751 and the first ring 755. The first ring 755 is slidably connected to the first annular groove 742. The second ring 756 is slidably connected to the second annular groove 743. The heating gun 757 is fixedly connected to the second through hole 7521.

[0034] The top cylinder 73 drives the heating mechanism 75 to rotate spirally toward the bottom cylinder 74. The liner 751 and the first ring 755 compress the first spring 754. At the same time, the first ring 755 slides along the first ring groove 742. The lower connecting rod 7536 and the cylinder shell 7538 squeeze the second spring 7537. The cylinder shell 7538 drives the second ring 756 to slide along the second ring groove 743. When testing the thermal insulation performance of the rock wool board, the heating gun 757 heats the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board to expand the air. At the same time, the sealing mechanism 76 and the air pressure mechanism 753 seal the space so that the expanded heated air can only flow out from the gap of the rock wool board and pass through the external temperature measuring mechanism 77. Detect the sealing and heat-insulating effect of the rock wool board; when detecting the stress strength of the rock wool board, the heating gun 757 sprays flames to generate heat energy while burning out the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board to generate negative pressure. At the same time, the heat energy generated by the heating gun 757 sprays flames to the air pressure mechanism 753 through the first air cylinder 752. The gas in the air pressure mechanism 753 expands due to heat and continues to seal, so that the top cylinder 73 and the bottom cylinder 74 are pressed and adsorbed on the surface of the rock wool board. When the pulling force continuously output by the push cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, the internal valve of the air pressure mechanism 753 can be opened to complete the pressure relief of the air inside the top cylinder 73, so that the bottom cylinder 74 is separated from the rock wool board.

[0035] like Figure 4 , Figure 5 , Figure 6As shown, the pneumatic mechanism 753 includes an outer cylinder 7531, a one-way ball valve 7532, a ring frame 7533, a second cylinder 7534, an upper connecting rod 7535, a lower connecting rod 7536, a second spring 7537 and a cylinder shell 7538. The outer cylinder 7531 is fixedly connected to the first through hole 732 and the second through hole 7521. The one-way ball valve 7532 is fixedly connected to the outer cylinder 7531, the upper connecting rod 7535 and the lower connecting rod 7536. The frame 7533 is fixedly connected to the outer cylinder 7531 and the second air cylinder 7534, the upper connecting rod 7535 is slidably connected to the second air cylinder 7534, the second spring 7537 is fixedly connected to the lower connecting rod 7536 and the cylinder shell 7538, the lower connecting rod 7536 is slidably connected to the cylinder shell 7538, the cylinder shell 7538 is fixedly connected to the second ring 756, and the upper connecting rod 7535 and the bottom of the second air cylinder 7534 form a sealed air cavity 7539.

[0036] When testing the thermal insulation performance of the rock wool board, the heating gun 757 heats the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board, causing the air to expand. The one-way gas flow direction of the one-way ball valve 7532 is from top to bottom, and the expanded heated air cannot escape from the one-way ball valve 7532. When testing the stress strength of the rock wool board, the air in the space formed by the top cylinder 73, the bottom cylinder 74 and the rock wool board is burned out to generate negative pressure, and at the same time, the temperature-sensitive gas in the sealed air cavity 7539 formed by the upper connecting rod 7535 and the bottom of the second gas cylinder 7534 is heated, causing the temperature-sensitive gas to expand and push the upper connecting rod 7535 upward, causing the upper connecting rod 7535 to pull the one-way ball valve 7532. The valve core seal of 532, when the pulling force continuously output by the pushing cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, the top cylinder 73 spirally rotates away from the bottom cylinder 74, and presses against the top of the cylinder shell 7538 through the lower connecting rod 7536. When the top of the cylinder shell 7538 continues to restrict the lower connecting rod 7536, as the pushing cylinder 71 continues to pull the outer cylinder 7531 away, the temperature-sensitive gas in the sealed air cavity 7539 composed of the upper connecting rod 7535 and the bottom of the second cylinder 7534 is reversely compressed, and the one-way ball valve 7532 opens, and the expanded air in the space composed of the top cylinder 73, the bottom cylinder 74 and the rock wool board is discharged by the one-way ball valve 7532.

[0037] like Figure 7 As shown, the sealing mechanism 76 includes a shell 761, a limiting spring piece 762, a limiting plate 763 and a third spring 764. The shell 761 is fixedly connected to the bottom tube 74 and the limiting spring piece 762. The limiting spring piece 762 is provided in a plurality of groups. The plurality of groups of limiting spring pieces 762 are linearly evenly distributed along the side wall of the shell 761. The limiting plate 763 is in contact with the limiting spring piece 762. The third spring 764 is fixedly connected to the shell 761 and the limiting plate 763.

[0038] The detection mechanism 7 is lowered as a whole, and the limit plate 763 contacts the upper surface of the rock wool board. As the detection mechanism 7 continues to descend, the limit plate 763 successively breaks through a number of linearly evenly distributed limit springs 762. Under the action of the third spring 764 restoring the deformation, the limit plate 763 presses against the upper surface of the rock wool board to complete the sealing.

[0039] like Figure 8 As shown, the temperature measuring mechanism 77 includes a bent rod 771, a sealing cover 772 and a temperature sensor 773. The bent rod 771 is fixedly connected to the fixing frame 72, and the sealing cover 772 is fixedly connected to the bent rod 771 and the temperature sensor 773.

[0040] The detection mechanism 7 is lowered as a whole, connected to the sealing cover 772 through the curved rod 771 assembled on the fixing frame 72, and contacts the upper surface of the rock wool board through the sealing cover 772. The temperature sensor 773 is used to detect the expanded and heated air flowing out of the gap of the rock wool board to judge the thermal insulation effect of the rock wool board. Through several groups of temperature measuring mechanisms 77 evenly distributed around the circumference of the fixing frame 72, the thermal insulation effect of each area in different directions can be judged.

[0041] Working principle of the present invention: This detection device is used to detect whether the thermal insulation performance and tensile stress strength perpendicular to the surface of the rock wool board made of fly ash resources are qualified. The rock wool board is transported to the bottom of the positioning mechanism 6 by the conveyor belt 5. The detection mechanism 7 adjusts its position in the two-dimensional coordinate plane and lowers it to be close to the upper surface of the rock wool board. The output end of the push cylinder 71 pushes the top cylinder 73 to spirally move toward the bottom cylinder 74. The liner 751 compresses the first spring 754, the first ring 755 slides along the first ring groove 742, and the lower connecting rod 7536 squeezes The second spring 7537 and the second ring 756 slide along the second ring groove 743; when testing the thermal insulation performance of the rock wool board, the heating gun 757 heats the air in the space formed by the top tube 73, the bottom tube 74 and the rock wool board to expand the air. The gas flow direction of the one-way ball valve 7532 is from top to bottom. The expanded and heated air cannot be leaked from the one-way ball valve 7532, but can only flow out from the gap of the rock wool board. The sealing and thermal insulation effect of the rock wool board is tested through the external temperature measuring mechanism 77; when testing the stress strength of the rock wool board, the heating gun 75 When the jet flame generates heat energy, the internal air burns out and generates negative pressure, which heats the temperature-sensitive gas in the sealed air cavity 7539, causing the temperature-sensitive gas to expand and push the upper connecting rod 7535 upward, pulling the valve core seal of the one-way ball valve 7532. When the pulling force continuously output by the pushing cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, the top cylinder 73 spirally rotates away from the bottom cylinder 74, and the lower connecting rod 7536 presses against the top of the cylinder shell 7538. As the pushing cylinder 71 continuously pulls the outer cylinder 7531 away, the sealing gas is reversely compressed. The temperature-sensitive gas in cavity 7539 opens the one-way ball valve 7532, and the expanded air in the internal space is released by the one-way ball valve 7532, so that the bottom cylinder 74 is separated from the rock wool board. When the strength of the rock wool board itself is insufficient, before the pulling force continuously output by the push cylinder 71 reaches the predetermined minimum stress strength standard of the rock wool board, the rock wool board will be damaged, making it impossible for the top cylinder 73 and the bottom cylinder 74 to be adsorbed. The sampled rock wool board is sampled and tested at multiple points to improve the detection integrity of the overall thermal insulation performance and stress strength of a single sampled rock wool board.
