DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] like Figures 1 to 8 As shown, the present invention provides an embodiment of a rapid backfill strength detection device for use in mining areas, comprising a supporting platform 2 for placing backfill samples, and also comprising an enclosure mechanism 3, a dumping mechanism 4, a cleaning mechanism 5, a sealing mechanism 6 and a top detection platform 7. The enclosure mechanism 3 comprises an enclosure frame 8 vertically slidably installed around the supporting platform 2. The enclosure mechanism 3 also comprises a first lifting seat 13 and a guide rail 14. The first lifting seat 13 and the guide rail 14 are respectively installed on both sides of the enclosure frame 8. The enclosure frame 8 is slidably connected to the guide rail 14 through a connecting piece. The first lifting seat 13 is used to drive the enclosure frame 8 to rise or fall along the guide rail 14.

[0026] The working principle of the enclosure mechanism 3 is: when it is necessary to test the filling body sample, if the filling body is still in an unsolidified state, the enclosure frame 8 is lifted by the first lifting seat 13, and then the filling body sample is filled into the enclosure frame 8, and the filling body sample is supported by the supporting platform 2 at the bottom, and then the top of the enclosure frame 8 is closed by the closing mechanism 6, so that the unsolidified filling body sample is solidified in a closed environment. On the one hand, it can reduce the influence of environmental factors on the solidification effect of the filling body sample. On the other hand, when the filling body sample is solidified and pressure tested, the enclosure frame 8 is driven down by the first lifting seat 13. At this time, the solidified filling body sample is located on the supporting platform 2, and finally the filling body sample is tested by the top detection platform 7. After the detection is completed, the sample is sent to the cleaning mechanism 5 through the dumping mechanism 4, and the supporting platform 2 is cleaned by the cleaning mechanism 5. After the cleaning is completed, the supporting platform 2 is reset, and the next batch of filling body samples can be tested.

[0027] The closing mechanism 6 includes a lifting top plate 9 and a detection tube 10. The edges of the supporting platform 2, the enclosure frame 8 and the lifting top plate 9 can enclose and form a closed cavity for accommodating the filling body sample. The detection tube 10 is fixed at the center of the lifting top plate 9 and can be connected to the closed cavity. The top detection platform 7 is slidably installed in the detection tube 10. The top detection platform 7 is used to detect the filling body sample.

[0028] The sealing mechanism 6 also includes a second lifting seat 15, a feed pipe 16, a liquid inlet pipe 17 and a hot air pipe 18. The second lifting seat 15 is used to drive the lifting top plate 9 to rise or fall. When the enclosure frame 8 rises to the top and the lifting top plate 9 falls to the lowest point, the supporting platform 2 is located at the bottom of the enclosure frame 8 and is sealed with the enclosure frame 8. The lifting top plate 9 is located at the top of the enclosure frame 8 and is sealed with the enclosure frame 8. The feed pipe 16 and the liquid inlet pipe 17 are fixed on the lifting top plate 9 and communicate with the closed cavity. The air duct 18 is fixed at the bottom of the detection cylinder 10 and is connected to the detection cylinder 10. The hot air flow transported by the hot air duct 18 will flow from the detection cylinder 10 into the closed cavity, thereby increasing the temperature in the closed cavity. The hot air duct 18 is connected to the bottom of the detection cylinder 10. On the one hand, it prevents the hot air flow from directly blowing the filling body sample in the closed cavity. On the other hand, when the hot air flow flows through the detection cylinder 10, it can also blow the top detection platform 7 in the detection cylinder 10 to keep the top detection platform 7 clean, thereby improving the detection accuracy of the top detection platform 7.

[0029] When the second lifting seat 15 drives the lifting top plate 9 to close the enclosure frame 8, the filling body sample can be sent into the closed cavity from the feeding pipe 16, and then water is added to the closed cavity through the liquid inlet pipe 17 to adjust the humidity in the closed cavity. Finally, the temperature in the closed cavity is adjusted through the hot air pipe 18, thereby simulating the solidification environment of the filling body sample in the pit, so that the filling body sample can solidify in a suitable environment.

[0030] A telescopic cylinder 19 is fixed to the top of the detection tube 10, and the piston rod of the telescopic cylinder 19 is fixedly connected to the top detection platform 7. The telescopic cylinder 19 is used to push the top detection platform 7 to press against the filling body sample. A pressure sensor is installed at the bottom of the top detection platform 7.

[0031] When the filling body sample has solidified, the second lifting seat 15 is used to drive the lifting top plate 9 to move to a suitable height, and then the telescopic cylinder 19 pushes the top detection platform 7 to press on the filling body sample, and then the pressure sensor is used to collect the pressure applied to the filling body sample when it is broken.

[0032] The dumping mechanism 4 includes a base 11 and a lever 12. One side of the supporting platform 2 is rotatably connected to the base 11. One end of the lever 12 is rotatably mounted on the base 11. The other end of the lever 12 is connected to the bottom of the supporting platform 2 via a slide rail. The lever 12 is used to push the supporting platform 2 to deflect toward the cleaning mechanism 5, and the cleaning mechanism 5 is used to clean the supporting platform 2.

[0033] The tipping mechanism 4 also includes a motor base 20 and a servo motor 21. The motor base 20 is fixed on the base 11. The servo motor 21 is installed on the motor base 20. The output shaft of the servo motor 21 is coaxially fixedly connected with the rotation center of the lever 12. The servo motor 21 is used to drive the lever 12 to rotate.

[0034] When the filling body sample test is completed, the servo motor 21 drives the lever 12 to deflect, and the lever 12 pushes one side of the supporting platform 2 to lift up, so that the supporting platform 2 as a whole is tilted toward the direction of the cleaning mechanism 5, so that the crushed filling body sample on the supporting platform 2 can be sent into the cleaning mechanism 5.

[0035] The cleaning mechanism 5 includes a dustproof box 22, and a cleaning port 23 is provided on one side of the dustproof box 22. A debris box 1 for collecting filling body samples is fixed to the bottom of the dustproof box 22. When the lever 12 pushes the supporting platform 2 to deflect into place, the edge of the supporting platform 2 can be engaged in the cleaning port 23 to prevent the dust generated during the cleaning of the supporting platform 2 from polluting the surrounding environment. The filling body sample can enter the debris box 1 from the cleaning port 23.

[0036] A cleaning brush 25, a brush seat 26, a nut seat 27, a screw 28 and a slide bar 29 are also installed in the dustproof box 22. The brush seat 26 is slidably installed on the slide bar 29, and the nut seat 27 is threadedly connected to the screw 28. The two ends of the cleaning brush 25 are rotatably connected to the brush seat 26 and the nut seat 27 respectively. A driving motor 30 is also fixed on the nut seat 27. The driving motor 30 is used to drive the cleaning brush 25 to rotate. The screw 28 and the slide bar 29 are vertically fixed in the dustproof box 22 and are respectively located on both sides of the cleaning port 23. The screw 28 is driven to rotate by the screw motor 24. When the screw 28 rotates, it can drive the nut seat 27 and the cleaning brush 25 to move along the surface of the supporting platform 2.

[0037] The working principle of the cleaning mechanism 5 is: after the supporting platform 2 is engaged in the cleaning port 23, the crushed filling body samples on the supporting platform 2 can be poured into the debris box 1 below for collection, and at the same time, the driving motor 30 drives the cleaning brush 25 to rotate, and then the screw motor 24 drives the screw 28 to rotate, and the rotation of the screw 28 drives the nut seat 27 to move up and down, so that the cleaning brush 25 rotatably installed on the nut seat 27 can move up and down with the nut seat 27. During the movement of the cleaning brush 25, the surface of the supporting platform 2 is cleaned to clean up the debris adhering to the supporting platform 2, so as to prevent the debris from affecting the stable placement of the next batch of filling body samples.

[0038] With the above-mentioned ideal embodiment of the present invention as inspiration, through the above-mentioned description content, relevant staff can make various changes and modifications without departing from the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the contents of the specification.
