The left and right ends of the bottom of the back of the frame 51 are equipped with wheels 52, the top of the back of the frame 51 is equipped with a push rod 53, and the connecting seat 54 is hingedly installed in the middle groove of the bottom surface of the front end of the frame 51. The top surface of the front end of the connecting seat 54 is provided with a docking groove 55, and the connecting seat 54 can be The docking groove 55 is snapped into the bottom of the side of the bracket 2, and a connecting hole 56 is opened on the side wall of the docking groove 55. A screw 57 is threadedly connected to the threaded hole at the front end of the connecting seat 54. The screw 57 can pass through the docking groove 55 and be threadedly connected to the inner side of the connecting hole 56. A mounting hole 58 is set through the side of the bracket 2. The screw 57 can pass through the mounting hole 58 and then be screwed into the inner side of the connecting hole 56, so as to lock the bracket 2 on the inner side of the docking groove 55. A tilt adjustment mechanism 59 is set on the frame 51.

[0026] It is further explained that the number of screw rods 57 is not less than 2, and the number of mounting holes 58 and connecting holes 56 is consistent with the number of screw rods 57, so as to ensure that the connecting seat 54 and the bracket 2 have sufficient connection strength.

[0027] To further explain, the four sides of the bracket 2 are all provided with mounting holes 58, so that the frame 51 can be connected and combined with the bracket 2 from all directions, and the adjustability is good.

[0028] To further explain, two auxiliary lines are set on the side of the bracket 2, the mounting hole 58 is located between the two auxiliary lines, and the spacing between the auxiliary lines matches the width of the connecting seat 54. When the connecting seat 54 is assembled with the bracket 2, the position of the connecting seat 54 can be adjusted according to the auxiliary lines so that the screw 57 and the mounting hole 58 are positioned synchronously.

[0029] To further explain, the rear ends of both sides of the push rod 53 are welded with support brackets 531. When the support brackets 531 and the wheels 52 touch the ground together, the connecting seat 54 will be perpendicular to the ground, so that the connecting seat 54 can lift the bracket 2 to a vertical state for detection in the direction parallel to the coal seam.

[0030] The inclination angle adjustment mechanism 59 of the utility model includes an electric push rod 591, a battery 592 and a controller 593. The frame 51 is hinged to the top of the electric push rod 591. The electric push rod 591 is longitudinally arranged. The telescopic end of the electric push rod 591 is hinged to the connecting seat 54. The connecting seat 54 is controlled to flip up and down by the electric push rod 591 to achieve the inclination angle adjustment of the bracket 2. A battery 592 is installed in the middle of the back of the frame 51, and the battery 592 supplies power to the electric push rod 591. The controller 593 is installed on the side of the push rod 53, and the controller 593 controls the electric push rod 591 to operate.

[0031] To further explain, the electric push rod 591 controls the connection base 54 to flip over at an angle of not less than 90 degrees, so that the connection base 54 has a sufficient tilt adjustment range to facilitate adjustment of the detection surface of the electromagnetic coil.

[0032] Here’s how it works:

[0033] First, fully charge the transient electromagnetic instrument body 1 and the battery 592 to ensure that the device has sufficient power to last, and then connect the cables of the transmitting coil 3 and the receiving coil 4 to the transient electromagnetic instrument body 1 to establish a signal connection between the transient electromagnetic instrument body 1 and the transmitting coil 3 and the receiving coil 4.

[0034] Second, water disaster is one of the main disasters in the process of mining construction and production. The transient electromagnetic instrument body 1 can be used to conduct advance detection of water-containing bodies. First, operate the electromagnetic instrument body 1 to start the detection system. When the system is working, the transmitting coil 3 emits an electromagnetic field. During the interval of a pulse magnetic field, the secondary eddy current field is observed with the help of the receiving coil 4, and the geoelectric characteristics of different depths can be obtained. The data can reflect the geological anomalies of the top of the coal seam, the bottom rock layer or the parallel coal seam, and help the construction team detect water bodies in the coal seam.

[0035] Third, during the detection process, the electromagnetic coil needs to be moved to each measuring point in turn, and each measuring point needs to detect multiple directions, resulting in a large amount of detection work. By setting an auxiliary device 5 on the side of the bracket 2, the frame 51 is first connected and combined with the bracket 2, and the connecting seat 54 is snapped into the bottom of the side of the bracket 2 through the docking groove 55, and then the screw 57 is tightened to make the screw 57 pass through the mounting hole 58 and screw into the inside of the connecting hole 56 to lock the bracket 2 on the inside of the docking groove 55, so that the frame 51 and the bracket 2 are connected and fixed as a whole, and the bracket 2 can be transported with the help of the frame 51.

[0036] Fourth, when the electromagnetic coil needs to be moved to the next measuring point, the staff member holds the push rod 53 to control the frame 51 to tilt backward. At this time, the frame 51 tilts with the wheel 52 as the fulcrum, so that the bracket 2 is lifted off the ground, and the electromagnetic coil can be transported by pushing / pulling the frame 51 through the push rod 53. After arriving at the measuring point, the push rod 53 is used to control the frame 51 to tilt and reset, so as to put the bracket 2 back to the ground, allowing the electromagnetic coil to continue the detection work, thereby facilitating the transportation and movement of the electromagnetic coil and improving the detection work efficiency.

[0037] Fifth, when it is necessary to adjust the detection direction of the electromagnetic coil, the staff will hold the push rod 53 to control the frame 51 to tilt backward until the tripod 531 and the wheel 52 touch the ground together, and let the connecting seat 54 lift the bracket 2 to a vertical state so as to detect the direction parallel to the coal seam. By setting an inclination adjustment mechanism 59 on the frame 51, the telescopic state of the electric push rod 591 can be controlled by the controller 593. When the electric push rod 591 is in the extended state, the electric push rod 591 drives the connecting seat 54 to flip downward. At this time, the electromagnetic coil faces downward, and can detect the direction of the bottom rock layer. When the electric push rod 591 is in the contracted state, the electric push rod 591 drives the connecting seat 54 to flip upward. At this time, the electromagnetic coil faces upward, and can detect the direction of the coal seam top. It is convenient to adjust the detection direction of the electromagnetic coil, and the operation is more convenient, which effectively improves the detection work efficiency.

[0038] The utility model provides a transient electromagnetic detection device for coal mine excavation work. An auxiliary device 5 is arranged on the side of a bracket 2, and a frame 51 is connected and combined with the bracket 2. When the electromagnetic coil needs to be moved to the next measuring point, the staff holds the push rod 53 to control the frame 51 to tilt backward, so that the bracket 2 is lifted off the ground, and the electromagnetic coil can be transported by pushing / pulling the frame 51 through the push rod 53. After arriving at the measuring point, the bracket 2 is put back on the ground, so that the electromagnetic coil continues to carry out detection work, which is convenient for transporting and moving the electromagnetic coil and improving the detection work efficiency. By arranging an inclination adjustment mechanism 59 on the frame 51, the telescopic state of the electric push rod 591 can be controlled by the controller 593. When the electric push rod 591 is in the extended state, the electromagnetic coil faces downward and can detect the direction of the bottom plate rock layer. When the electric push rod 591 is in the retracted state, the electromagnetic coil faces upward and can detect the direction of the coal seam top. It is convenient to adjust the detection direction of the electromagnetic coil, and the operation is more convenient, which effectively improves the detection work efficiency.
