Problems solved by technology
[0004] Due to the large area of the transmitting coil, it is necessary to have a support structure suitable for the coil, which is not easily deformed and easy to place. At the same time, the coil and its support structure need to be moved by manpower, so the weight of the support structure must be light enough; because the transient electromagnetic method must use The transmitting coil is charged to generate a magnetic field, so the supporting structure cannot use materials with high dielectric properties such as metal; the coil must be parallel to the face of the palm, and there will be errors if it is not parallel, and the angle is difficult to control. It is inevitable that shaking will affect the accuracy of the results and affect the later data processing

Embodiment 1
[0040] This embodiment discloses a foldable transient electromagnetic coil carrying device, including a driving component, a carrying component, and a coil winding component;
[0041] Driving components, mounting components, and coil winding components: the coil winding components include: a small fixed pulley, that is, the winding fixed pulley 1, which provides a moving path for the coil to be wound on the wire frame. The large fixed pulley is the winder 5, which winds and stores the coil.
[0042] See attached Figure 1-6 As shown, the wire frame is formed by connecting four rods 2 through rotatable loose bolts. The receiving probe fixing device includes two intersecting rods 2 in the wire frame and a hollow bolt 10 in the middle. The wire frame supporting device is composed of two hollow pipes 6, which can control the angle. Pulley comprises a fixed rod 11, a small fixed pulley 1. Winder is made up of a crank 3 and big pulley 5.
[0043] The wire frame is composed of f...

The invention discloses a foldable transient electromagnetic coil carrying device and a using method thereof. The foldable transient electromagnetic coil carrying device comprises a foldable wire frame, a driving part and a coil winding component. The driving part is arranged on the foldable wire frame, and a coil is driven by the driving part to move to the coil winding component and is wound under the effect of the coil winding component. According to the foldable wire frame, a wire frame supporting device is used for supporting the wire frame, and the angle between the foldable wire frame and the wire frame supporting device is adjusted to enable points on a coil plane to be equidistant from a tunnel face. By means of a common device, the device is well and comprehensively utilized, themechanization degree is high, and the defects that a fixed carrying device used at present cannot walk, installation is not standard, the automation degree is low, the labor intensity of constructorsis high, and measurement is inaccurate are overcome.
Description
technical field [0001] The invention belongs to the fields of winding and data measurement of transient electromagnetic coils, and in particular relates to a foldable transient electromagnetic coil carrying device and a method for using the same. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The transient electromagnetic method (Transient Electromagnetic Method, TEM) is a very important method in the field of geophysical exploration. It uses an ungrounded return line or a grounded line source to emit a pulsed electromagnetic field underground, and observes the underground eddy current field during a pulse interval. Due to its sensitivity to low-resistivity bodies, the method has become the preferred method for geological problems such as geological structure exploration and geological mineral exploration. In order to ensure that the tr...
