[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0034] Embodiment: As Figures 1-6 shown, the present invention provides a technical solution for a clay backfill compaction device with a compaction degree detection function, which is characterized in that: the clay backfill compaction device with a compaction degree detection function includes a workbench 1, three sliding holes 3 are opened on the workbench 1, three mounting seats 4 are installed on the workbench 1, three mounting through holes 5 are opened in the three mounting seats 4, the mounting through holes 5 are coaxial with the sliding holes 3, moving iron cores 6 are slidably installed in the mounting through holes 5, the moving iron cores 6 are connected with the upper ends of the sliding holes 3 through buffer return springs 10, the lower ends of the three moving iron cores 6 penetrate through the sliding holes 3 and are connected through a compaction plate 12, an upper cover body 7 is installed above the mounting seat 4, a static iron core 8 is installed in the upper cover body 7, a coil 9 is installed outside the static iron core 8, a central processor 13 is installed on the workbench 1, and the coil 9 is connected with the central processor 13 through a compaction circuit 14

[0035] When it is necessary to flatten the backfill clay, the central processing unit 13 inputs sinusoidal alternating current into the coil. Through electromagnetic induction, the static iron core 8 generates a magnetic force with changing direction and magnitude on the moving iron core 6. The moving iron core 6 drives the compaction plate 12 to reciprocate up and down at a high frequency, realizing the compaction of the backfill clay, improving work efficiency and ensuring compaction quality.

[0036] A buffer pad 11 is installed in the sliding hole 3, and the inner diameter of the buffer pad 11 is the same as the outer diameter of the moving iron core 6.

[0037] When the moving iron core 6 drives the compaction plate 12 to reciprocate up and down, it is easy to affect the stability of the entire workbench 1 due to radial and axial shaking, and damage the electrical components on the workbench 1. The provided buffer pad 11 and buffer reset spring 10 can effectively relieve radial and axial shaking, ensure the stability of the workbench 1, and extend the service life of the device.

[0038] An electric telescopic rod 15 is installed at the lower end of the workbench 1. A drill bit 16 is installed at the end of the electric telescopic rod 15. A pressure sensor 17 is installed at the upper end of the drill bit 16. The electric telescopic rod 15 is electrically connected to the central processing unit 13.

[0039] After the compaction work is completed, the central processing unit 13 sends an electrical signal to control the electric telescopic rod 15 to extend, so that the drill bit 16 is inserted into the compacted clay. According to the data transmitted back by the pressure sensor 17, the compactness of the clay after compaction is judged. According to the detection results, the compaction time is adjusted to further ensure the compaction work quality.

[0040] A leveling component 18 is arranged on the workbench 1. The leveling component 18 obtains driving force through the up and down reciprocating motion of the moving iron core 6. An adjusting component 19 is arranged on the workbench 1. The adjusting component 19 obtains driving force through the up and down reciprocating motion of the moving iron core 6 and the motion of the compaction plate 12.

[0041] As Figures 1-7 shown, the leveling component 18 includes an outer horizontal sliding groove 1801, a mounting block 1802, a reciprocating screw 1803, a slider 1804, a triangular scraping plate 1805, a right-side driven gear 1806, an inner vertical sliding groove 1807, a connecting column 1808, a slide rail 1809, a driven column 1810, a turntable 1811, a transmission column 1812, a right-side driving gear 1813, a right-side first transmission gear 1814, a right-side second transmission gear 1815, a mounting rod 1816 and a right-side working chamber 1817;

[0042] Two outer horizontal sliding grooves 1801 are symmetrically formed in the workbench 1. Two mounting blocks 1802 are symmetrically installed on the workbench 1. The two mounting blocks 1802 are connected by a reciprocating screw 1803. The reciprocating screw 1803 has driving threads at both ends, and the driving threads at both ends are centrosymmetric. Two sliders 1804 are slidably installed on the reciprocating screw 1803. The sliders 1804 penetrate through the outer horizontal sliding grooves 1801. Triangular scraping plates 1805 are installed at the lower ends of the two sliders 1804. A right-side driven gear 1806 is installed at the middle position of the reciprocating screw 1803. A right-side working chamber 1817 is formed in the mounting seat 4. The right-side working chamber 1817 is communicated with the mounting through-hole 5 through an inner vertical sliding groove 1807. A connecting column 1808 is installed at the upper end of the moving iron core 6. The connecting column 1808 penetrates through the inner vertical sliding groove 1807, and a slide rail 1809 is installed at the end. A driven column 1810 is slidably installed in the slide rail 1809. A turntable 1811 is rotatably installed in the right-side working chamber 1817. The end of the driven column 1810 is connected to the turntable 1811. The position of the driven column 1810 on the turntable 1811 deviates from the center of the circle. A transmission column 1812 is installed on the turntable 1811. The transmission column 1812 penetrates through the mounting seat 4. A right-side driving gear 1813 is installed at the end of the transmission column 1812. A mounting rod 1816 is rotatably installed on the mounting seat 4. A right-side first transmission gear 1814 and a right-side second transmission gear 1815 are installed on the mounting rod 1816. The right-side first transmission gear 1814 meshes with the right-side driving gear 1813. The right-side second transmission gear 1815 meshes with the right-side driven gear 1806.

[0043] When the moving iron core 6 moves up and down reciprocally, the slide rail 1809 is driven to move up and down through the connecting column 1808. When the slide rail 1809 moves up and down, the driven column 1810 is driven to move in the vertical direction. Because the driven column 1810 is eccentrically installed on the turntable 1811, when the driven column 1810 moves up and down, the turntable 1811 will be driven to rotate. The turntable 1811 will drive the left-side driving gear 1922 to rotate synchronously through the transmission column 1812. Since the right-side first transmission gear 1814 meshes with the right-side driving gear 1813, and the right-side second transmission gear 1815 meshes with the right-side driven gear 1806, the right-side driving gear 1813 finally drives the right-side driven gear 1806 to rotate, so that the reciprocating screw 1803 rotates. When the reciprocating screw 1803 rotates, it drives the slider 1804 to drive the triangular scraping plate 1805 to level the backfilled clay, preventing the uneven dispersion of the backfill soil from causing uneven thickness and affecting the subsequent compaction work.

[0044] As Figures 1-6 and Figures 8-9As shown, the adjustment assembly 19 includes a working chamber 1901, a sealed air chamber 1902, a positioning chute 1903, an annular track 1904, an annular chute 1905, a rotating column 1906, a horizontal push rod 1907, a positioning rod 1908, a cross-shaped push plate 1909, a connecting plate 1910, a contact arc plate 1911, a pressure return spring 1912, a pressure hole 1913, a pressure relief hole 1914, an air outlet valve 1915, a pressure chamber 1916, an intake pipe 1917, an exhaust pipe 1918, a piston plate 1919, a vertical push rod 1920, a pressure pipeline 1921, a left driving gear 1922, a left transmission gear 1923, and a left driven gear 1924;

[0045] A working chamber 1901 is provided on the workbench 1. The outermost annular opening of the working chamber 1901 is a sealed air chamber 1902. Three positioning chutes 1903 are provided on the inner wall surface of the sealed air chamber 1902. An annular track 1904 is connected to the sealed air chamber 1902 through the positioning chutes 1903. An annular chute 1905 is provided on the inner wall surface of the annular track 1904. A rotating column 1906 is rotatably installed at the center position of the working chamber 1901. The rotating column 1906 penetrates through the working chamber 1901 and extends out of the workbench 1. A horizontal push rod 1907 is installed on the rotating column 1906. The horizontal push rod 1907 passes through the annular chute 1905 and contacts the outer wall surface of the annular track 1904. A positioning rod 1908 is slidably installed in the annular track 1904. The lower end of the positioning rod 1908 extends out of the workbench 1. The end of the positioning rod 1908 is connected to the electric telescopic rod 15. A left working chamber 1925 is provided on the mounting seat 4. The same driving mechanism as that in the right working chamber 1817 is provided in the left working chamber 1925. One end of the transmission column 1812 of the left working chamber 1925 extending out of the mounting seat 4 is installed with a left driving gear 1922. A left transmission gear 1923 is rotatably installed on the workbench 1. The left transmission gear 1923 meshes with the left driving gear 1922. A left driven gear 1924 is installed at the upper end of the rotating column 1906. The left driven gear 1924 meshes with the left transmission gear 1923.

[0046] A pressure chamber 1916 is installed below the workbench 1. An intake pipe 1917 and an exhaust pipe 1918 are installed on the pressure chamber 1916. Both the intake pipe 1917 and the exhaust pipe 1918 are one-way air pipes. A piston plate 1919 is slidably installed in the pressure chamber 1916. The lower end of the piston plate 1919 is connected to the compaction plate 12 through a vertical push rod 1920. Pressurizing holes 1913 and pressure relief holes 1914 are formed in the outer wall of the sealed air chamber 1902. The pressurizing holes 1913 are connected to the exhaust pipe 1918 through a pressurizing pipeline 1921. A cross-shaped push plate 1909 is slidably installed in the three positioning chutes 1903. A contact arc plate 1911 is installed on one of the cross-shaped push plates 1909, and one connecting plate 1910 and two connecting plates 1910 are respectively installed on the other two cross-shaped push plates 1909. A contact arc plate 1911 is installed on the innermost connecting plate 1910.

[0047] A touch sensor is provided on the contact arc plate 1911, and the touch sensor is electrically connected to the central processor 13.

[0048] When the moving iron core 6 reciprocates up and down, through the same driving method as in the leveling assembly 18, the transmission column 1812 rotates, so as to drive the left transmission gear 1923 to rotate through the meshing of the left transmission gear 1923 and the left driving gear 1922. Then, the left driven gear 1924 is driven to rotate through the meshing of the left driven gear 1924 and the left transmission gear 1923. The left driven gear 1924 drives the horizontal push rod 1907 to perform a circular motion around the rotating column 1906 through the rotating column 1906. The horizontal push rod 1907 can push the positioning rod 1908 to drive the electric telescopic rod 15 to reach different detection positions for detection;

[0049] When the compaction plate 12 moves downward, the piston plate 1919 is driven to move downward synchronously by the vertical push rod 1920. The air pressure in the pressurizing chamber 1916 decreases, and the outside air enters the pressurizing chamber 1916 from the air inlet pipe 1917. When the compaction plate 12 moves upward, the air pressure in the pressurizing chamber 1916 increases, and the gas is discharged from the air outlet pipe 1918, enters the sealed air chamber 1902 through the pressurizing pipeline 1921 and the pressurizing hole 1913, so that the pressure in the sealed air chamber 1902 increases. The increased pressure in the sealed air chamber 1902 will push the cross push plate 1909, the connecting plate 1910 and the contact arc plate 1911 to move towards the center along the positioning chute 1903. When the contact arc plate 1911 moves to be flush with the annular track 1904, the horizontal push rod 1907 will push the positioning rod 1908 to continue moving to the next positioning chute 1903. When the pressure is not enough to push the positioning rod 1908 to reach the annular track 1904, the touch sensor on the contact arc plate 1911 will send an electrical signal to control the telescopic electric rod 15 to extend and contract, completing a compaction degree detection. Until reaching the next detection position, another compaction degree detection is carried out, realizing multi-point compaction degree detection of the flattened position, making the detection result more referenceable and more guiding for the compaction operation, and ensuring the compaction quality.

[0050] At the connection of the annular track 1904 and the positioning chute 1903, a fillet treatment is done to ensure that when the horizontal push rod 1907 pushes the positioning rod 1908 to reach the positioning chute 1903, it can enter the positioning chute 1903 to ensure the normal operation of the device.

[0051] An air outlet valve 1915 is installed at the end of the pressure relief hole 1914, and the air outlet valve 1915 is electrically connected to the central processing unit 13.

[0052] After every three compaction degree detections, the central processing unit 13 sends an electrical signal to control the opening of the air outlet valve 1915 to release the high-pressure gas in the sealed air chamber 1902, so that the detection device stops moving, preventing jamming and damaging the equipment.

[0053] The position of the sliding hole 3 is between the leveling component 18 and the adjusting component 19. Four electric wheels 2 are installed at the lower end of the workbench 1, and the electric wheels 2 are electrically connected to the central processing unit 13.

[0054] The clay backfill compaction device with the function of compaction degree detection first performs the leveling treatment of the backfill soil, then performs the compaction operation, and finally detects the compaction degree. Therefore, the compaction part is located between the leveling part and the detection device to ensure the reasonable operation among the institutions.

[0055] The working principle of the present invention:

[0056] When it is necessary to compact the backfill clay, the central processing unit 13 inputs sinusoidal alternating current to the coil. Through electromagnetic induction, the static iron core 8 generates a magnetic force with changing direction and magnitude on the moving iron core 6. The moving iron core 6 drives the compaction plate 12 to reciprocate up and down at a high frequency, thereby compacting the backfill clay, improving work efficiency and ensuring compaction quality.

[0057] When the moving iron core 6 drives the compaction plate 12 to reciprocate up and down, radial and axial shaking may easily affect the stability of the entire workbench 1 and damage the electrical components on the workbench 1. The provided buffer pad 11 and buffer return spring 10 can effectively alleviate the radial and axial shaking, ensure the stability of the workbench 1, and extend the service life of the device.

[0058] After the compaction work is completed, the central processor 13 sends an electrical signal to control the extension of the electric telescopic rod 15, so that the drill bit 16 is inserted into the compacted clay. According to the data sent back by the pressure sensor 17, the compaction degree of the compacted clay is judged. According to the detection result, the compaction time is adjusted to further ensure the quality of the compaction work.

[0059] When the moving iron core 6 reciprocates up and down, the connecting column 1808 drives the slide rail 1809 to move up and down. When the slide rail 1809 moves up and down, it drives the driven column 1810 to move in the vertical direction. Because the driven column 1810 is eccentrically installed on the turntable 1811, when the driven column 1810 moves up and down, it will drive the turntable 1811 to rotate. The turntable 1811 will drive the left driving gear 1922 to rotate synchronously through the transmission column 1812. 814 is meshed with the right driving gear 1813, and the right second transmission gear 1815 is meshed with the right driven gear 1806, so the right driving gear 1813 eventually drives the right driven gear 1806 to rotate, thereby causing the reciprocating screw 1803 to rotate. When the reciprocating screw 1803 rotates, the driving slider 1804 drives the triangular scraper 1805 to scrape the backfill clay flat to prevent uneven dispersion of the backfill soil and cause thickness, thereby affecting subsequent compaction work.

[0060] When the moving iron core 6 reciprocates up and down, the driving column 1812 is rotated by the same driving method as in the smoothing assembly 18, thereby driving the left transmission gear 1923 to rotate through the meshing of the left transmission gear 1923 and the left driving gear 1922, and then driving the left driven gear 1924 to rotate through the meshing of the left driven gear 1924 and the left transmission gear 1923. The left driven gear 1924 drives the horizontal push rod 1907 to perform a circular motion around the rotating column 1906 through the rotating column 1906, and the horizontal push rod 1907 can push the positioning rod 1908 to drive the electric telescopic rod 15 to reach different detection positions for detection;

[0061] When the compaction plate 12 moves downward, the piston plate 1919 is driven to move downward synchronously by the vertical push rod 1920. The air pressure in the pressurizing chamber 1916 decreases, and the outside air enters the pressurizing chamber 1916 from the air inlet pipe 1917. When the compaction plate 12 moves upward, the air pressure in the pressurizing chamber 1916 increases, and the gas is discharged from the air outlet pipe 1918 and enters the sealed air chamber 1902 through the pressurizing pipeline 1921 and the pressurizing hole 1913, increasing the pressure in the sealed air chamber 1902. The increased pressure in the sealed air chamber 1902 will push the cross push plate 1909, the connecting plate 1910 and the contact arc plate 1911 to move towards the center along the positioning chute 1903. When the contact arc plate 1911 moves flush with the annular track 1904, the horizontal push rod 1907 will push the positioning rod 1908 to continue moving to the next positioning chute 1903. When the pressure is not sufficient to push the positioning rod 1908 to reach the annular track 1904, the touch sensor on the contact arc plate 1911 will emit an electrical signal to control the telescopic electric rod 15 to extend and contract, completing a compaction degree detection. Until the next detection position, another compaction degree detection is carried out to achieve multi-point compaction degree detection of the flattened position, making the detection result more referenceable and more guiding for the compaction operation, and ensuring the compaction quality.

[0062] At the connection of the annular track 1904 and the positioning chute 1903, a fillet is made to ensure that when the horizontal push rod 1907 pushes the positioning rod 1908 to reach the positioning chute 1903, it can enter the positioning chute 1903 to ensure the normal operation of the device.

[0063] After every three compaction degree detections, the central processor 13 emits an electrical signal to control the air outlet valve 1915 to open and release the high-pressure gas in the sealed air chamber 1902, so that the detection device no longer moves, preventing jamming and damaging the equipment.

[0064] The clay backfill compaction device with the attached compaction degree detection function first levels the backfill soil, then performs the compaction operation, and finally detects the compaction degree. Therefore, the compaction part is located between the leveling part and the detection device to ensure the reasonable operation of each mechanism.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
