[0009] As a further limitation of this technical solution, the base plate is made of cast iron.

[0010] A method for omnidirectional detection of coal mine roadways, characterized by comprising the following steps: Step 1: Install this device onto the moving mechanism, which will then drive the device to move in the forward and backward directions and to turn. Step 2: Operate the moving mechanism to move the device to the test point, and install an appropriate number of test components according to the requirements of the test point; Step 3: Based on the location of the test point, operate the electric push rod one to move the test component to the appropriate position; Step 4: By controlling the electric turntable, the electric turntable drives the second round rod to move along the arc groove and the straight groove.

[0011] As a further limitation of this technical solution, based on the selection of the tapping point in step two: Install three sets of test components, arranging them in an equilateral triangle. For three points on the same horizontal plane at the top of the arc of the roadway, operate the moving mechanism so that the three perpendicular lines of the equilateral triangle intersect the cross section along the length of the roadway. When the equilateral triangle moves to the horizontal plane position, it has three intersection points with the horizontal plane. For two points on the same horizontal plane at the top of the arc of the tunnel, operate the moving mechanism to make the line connecting the two sets of test components that need to be used perpendicular to the cross section in the length direction of the tunnel. For a point on the same horizontal plane at the top of the arc of the tunnel, operate the moving mechanism to make the vertical line from which the test component to be used is perpendicular to the cross section along the length of the tunnel.

[0012] As a further limitation of this technical solution, the specific processes of step five and step seven are as follows: The electric push rod three extends, causing the support block two to move. The support block two then moves the support plate, the torsion spring, the trapezoidal block, the retaining arc, and the arc plate, causing the arc plate to contact the circular shaft one. The circular shaft one then expands the arc plate, compressing the torsion spring until the circular shaft one enters the retaining arc forming area. The torsion spring then recovers, the electric push rod three retracts, and the retaining arc causes the circular shaft one to move along the track groove. The circular shaft one causes the connecting plate to swing, the connecting plate causes the circular block to swing, and the circular block causes the cross shaft to move along the arc groove. The cross shaft then moves the spring three and the measuring... The test hammer swings, the cross shaft drives the V-rod to swing, the V-rod stretches the second spring and drives the second spring to swing, thus storing force in the second spring. The second spring drives the second round shaft to rotate, the cross shaft stretches the first spring and drives the first spring to swing, thus storing force in the first spring. The first spring drives the short shaft to rotate. When the trapezoidal block contacts the long plate, the trapezoidal block moves along the long plate, causing the adjacent support plates to separate. The support plates drive the locking arc to move, making the distance between adjacent locking arcs greater than the diameter of the first round shaft. The first spring and the second spring return to their original positions, the first round shaft disengages from the locking arc, and the test hammer swings to strike the test point.

[0013] As a further limitation of this technical solution, a sound wave receiver is installed on the moving mechanism to observe and analyze acoustic parameters such as wave speed, wave amplitude, and waveform of the sound waves.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are: 1. This device, through the setting of a track groove, moves the area composed of a torsion spring, support plate, locking arc, and circular arc plate under the drive of electric push rod three. When the circular arc plate contacts the circular shaft one, the torsion spring stretches, causing the locking arc to lock the circular shaft one, moving the circular shaft one along the track groove. This causes the cross shaft to move along the circular arc groove, stretching the V-rod and causing spring two to swing, thus storing force in spring two. Spring two then drives the circular shaft two to rotate, and the cross shaft stretches spring one and causes spring one to swing, thus storing force in spring one. This provides sufficient force for the test hammer. When the trapezoidal block contacts the long plate, the trapezoidal block moves along the long plate, separating the adjacent support plates. The support plates drive the locking arc to move, making the distance between adjacent locking arcs greater than the diameter of the circular shaft one. Spring one and spring two then return to their original positions, the circular shaft one disengages from the locking arc, and the test hammer swings to strike the test point, completing the striking test.

[0015] 2. This device uses an electric push rod to move the test component to a suitable height and an electric turntable to swing it to the appropriate position. The combined action of the electric push rod and the turntable allows for position adjustment of the test component, enabling testing of roadways of different heights and widths. It is easy to use. Through its ingenious design, the device allows for tapping of the roadway, with selectable single, double, or triple tapping points. Utilizing rock mass acoustic wave detection technology, it detects the stress in the surrounding rock of the roadway, facilitating omnidirectional testing of coal mine roadways.

[0031] The base plate 7 is made of cast iron.

[0032] A method for omnidirectional detection of coal mine roadways includes the following steps: Step 1: Install this device onto the moving mechanism, which will then drive the device to move in the forward and backward directions and to turn. Step 2: Operate the moving mechanism to move the device to the test point, and install an appropriate number of test components according to the requirements of the test point; Step 3: Based on the location of the test point, operate the electric push rod 5 to move the test component to the appropriate position; Step 4: By controlling the electric turntable 2, the electric turntable 2 drives the second round rod 16 to move along the arc groove 17 and the straight groove 12, the second round rod 16 drives the cylinder 15 to move along the round groove 13, and the cylinder 15 drives the test component to swing, so that the test component swings to a suitable position. Step 5: Operate the electric push rod 21 to make the arc plate 42 lock the circular shaft 28, control the electric push rod 21 to retract, and make the spring 31 and the spring 32 store force. When the trapezoidal block 43 contacts the long plate 23, control the electric push rod 21 to stop. Step Six: Operate the electric push rod 210. The electric push rod 210 drives the cross rod 9 to move along the cross groove 19. The cross rod 9 drives the square rod 20 to swing, so that the test component swings to a suitable position and is in close contact with the test point. Step 7: Control the electric push rod 21 to continue retracting, so that the trapezoidal block 43 moves along the long plate 23, so that the adjacent support plates 40 separate, so that the distance between the adjacent locking arcs 41 is greater than the diameter of the round shaft 28, the spring 31 and the spring 32 return to their original positions, so that the test hammer 35 swings and strikes the test point.

[0033] Based on the selection of the tapping point in step two: Install three sets of test components, arranging them in an equilateral triangle. For three points on the same horizontal plane at the top of the arc of the roadway, operate the moving mechanism so that the three perpendicular lines of the equilateral triangle intersect the cross section along the length of the roadway. When the equilateral triangle moves to the horizontal plane position, it has three intersection points with the horizontal plane. For two points on the same horizontal plane at the top of the arc of the tunnel, operate the moving mechanism to make the line connecting the two sets of test components that need to be used perpendicular to the cross section in the length direction of the tunnel. For a point on the same horizontal plane at the top of the arc of the tunnel, operate the moving mechanism to make the vertical line from which the test component to be used is perpendicular to the cross section along the length of the tunnel.

[0034] The specific procedures for steps five and seven are as follows: The electric push rod 21 extends, causing the support block 27 to move. The support block 27 then moves the support plate 40, the torsion spring 39, the trapezoidal block 43, the retaining arc 41, and the arc plate 42, causing the arc plate 42 to contact the circular shaft 28. The circular shaft 28 then expands the arc plate 42, compressing the torsion spring 39 until the circular shaft 28 enters the area formed by the retaining arc 41. The torsion spring 39 then recovers, and the electric push rod 21 retracts. The retaining arc 41 moves the circular shaft 28 along the track groove 44, causing the connecting plate 29 to swing. The connecting plate 29 then moves the circular block 30, which in turn moves the cross shaft 38 along the arc groove 24. The cross shaft 38 then moves the spring 36 and the... When the test hammer 35 swings, the cross shaft 38 drives the V-rod 37 to swing, the V-rod 37 stretches the second spring 32 and drives the second spring 32 to swing, thus storing force in the second spring 32. The second spring 32 drives the second circular shaft 33 to rotate, the cross shaft 38 stretches the first spring 31 and drives the first spring 31 to swing, thus storing force in the first spring 31. The first spring 31 drives the short shaft 34 to rotate. When the trapezoidal block 43 contacts the long plate 23, the trapezoidal block 43 moves along the long plate 23, causing the adjacent support plate 40 to separate. The support plate 40 drives the locking arc 41 to move, making the distance between adjacent locking arcs 41 greater than the diameter of the first circular shaft 28. The first spring 31 and the second spring 32 return to their original positions, the first circular shaft 28 disengages from the locking arc 41, and the test hammer 35 swings to strike the test point.

[0035] A sound wave receiver is installed on the moving mechanism to observe and analyze acoustic parameters such as wave speed, amplitude, and waveform of the sound waves.

[0036] The workflow of this invention is as follows: the device is installed on a moving mechanism, and the moving mechanism drives the device to move in the forward and backward direction and to turn.

[0037] The operating mechanism moves the device to the test point, where an appropriate number of test components are installed according to the requirements of the test point.

[0038] Based on the location of the test point, operate the electric push rod 5 to move the test component to the appropriate position.

[0039] By controlling the electric turntable 2, the electric turntable 2 drives the second round rod 16 to move along the arc groove 17 and the straight groove 12. The second round rod 16 drives the cylinder 15 to move along the round groove 13. The cylinder 15 drives the test component to swing, so that the test component swings to the appropriate position.

[0040] Operate the electric push rod 21, which moves the support block 27. The support block 27 moves the support plate 40, torsion spring 39, trapezoidal block 43, retaining arc 41, and arc plate 42, causing the arc plate 42 to contact the circular shaft 28. The circular shaft 28 opens the arc plate 42, compressing the torsion spring 39 until the circular shaft 28 enters the area formed by the retaining arc 41. The torsion spring 39 then recovers, the electric push rod 21 retracts, and the retaining arc 41 moves the circular shaft 28 along the track groove 44. The circular shaft 28 then moves the connecting plate. 29 swings, connecting plate 29 drives circular block 30 to swing, circular block 30 drives cross shaft 38 to move along arc groove 24, cross shaft 38 drives spring three 36 and test hammer 35 to swing, cross shaft 38 drives V rod 37 to swing, V rod 37 stretches spring two 32 and drives spring two 32 to swing, realizing spring two 32 storing force, spring two 32 drives circular shaft two 33 to rotate, cross shaft 38 stretches spring one 31 and drives spring one 31 to swing, realizing spring one 31 storing force, spring one 31 drives short shaft 34 to rotate. Arc plate 42 locks circular shaft one 28, controls electric push rod three 21 to retract, realizing spring one 31 and spring two 32 storing force, when trapezoidal block 43 contacts long plate 23, controls electric push rod three 21 to stop.

[0041] Operate the electric push rod 210, which drives the cross rod 9 to move along the cross groove 19. The cross rod 9 drives the square rod 20 to swing, so that the test component swings to a suitable position and is in close contact with the test point.

[0042] The electric push rod 21 continues to retract, causing the trapezoidal block 43 to move along the long plate 23. When the trapezoidal block 43 contacts the long plate 23, it moves along the long plate 23, causing the adjacent support plate 40 to separate. The support plate 40 drives the locking arc 41 to move, making the distance between the adjacent locking arcs 41 greater than the diameter of the round shaft 28. The spring 31 and the spring 32 return to their original positions, and the round shaft 28 disengages from the locking arc 41, causing the test hammer 35 to swing and strike the test point.

[0043] This device, through the setting of track groove 44, enables the movement of the area composed of torsion spring 39, support plate 40, locking arc 41, and arc plate 42 under the drive of electric push rod 21. When the arc plate 42 contacts the circular shaft 28, torsion spring 39 is stretched, causing locking arc 41 to lock the circular shaft 28, allowing the circular shaft 28 to move along track groove 44. This causes cross shaft 38 to move along arc groove 24, enabling V-rod 37 to stretch spring 32 and cause it to swing, thus storing force in spring 32. Spring 32 then drives circular shaft 33 to rotate, and cross shaft 38 stretches spring 31 and causes it to swing, thus storing force in spring 31. This provides sufficient force for the test hammer 35. When the trapezoidal block 43 contacts the long plate 23, the trapezoidal block 43 moves along the long plate 23, causing the adjacent support plate 40 to separate. The support plate 40 drives the locking arc 41 to move, so that the distance between the adjacent locking arcs 41 is greater than the diameter of the first round shaft 28. The first spring 31 and the second spring 32 return to their original positions, and the first round shaft 28 disengages from the locking arc 41, causing the test hammer 35 to swing and strike the test point, thus completing the striking test.

[0044] This device uses an electric push rod 5 to move the test component to a suitable height, and an electric turntable 2 to swing the test component to the appropriate position. Through the combined action of the electric push rod 5 and the electric turntable 2, the position of the test component can be adjusted, enabling testing of tunnels of different heights and widths. It is easy to use.

[0045] This device, through its ingenious design, enables the tapping of roadways. Each tap can be performed at one, two, or three points. Utilizing rock mass acoustic wave detection technology, it can detect the stress in the surrounding rock of the roadway, facilitating omnidirectional detection of coal mine roadways.
