Description

Technical Field

[0001] This utility model relates to the field of transient electromagnetic instrument technology, and specifically discloses a coil dragging device for a transient electromagnetic instrument. Background Technology

[0002] Transient electromagnetic instruments mainly consist of three components: the main unit, the power supply, and the coil. They are widely used in fields such as ore body depth and mineralized structure detection, aquifer and groundwater distribution detection, and underground structure detection. During the detection process, the coil of the transient electromagnetic instrument needs to be continuously moved, and the detection data from different locations are compared and analyzed to draw detection conclusions.

[0003] Currently, coil movement during detection is mainly achieved through manual handling or using manufacturer-supplied caster stands. This presents several problems: First, manual handling is time-consuming and labor-intensive. Second, manufacturer-supplied stands are generally difficult to disassemble and carry, and are only compatible with one type of coil. For scenarios requiring the simultaneous use of multiple transient electromagnetic instruments, multiple sets of caster stands are needed. Third, manufacturer-supplied coil stands typically use casters or swivel wheels, which are prone to swaying during actual dragging, especially in continuous sampling detection modes. Therefore, a coil dragging device for transient electromagnetic instruments is needed to solve this problem. Summary of the Invention

The device achieves rapid clamping and release of the coil through a threaded rod-tooth ring linkage mechanism, adapts to coils of different sizes, and adopts an optimized roller traction design to ensure linear dragging stability, effectively improving detection efficiency and data reliability.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-3 A coil dragging device for a transient electromagnetic instrument includes a base plate 1, a through hole 2 through the upper end face of the base plate 1, a coil fixing mechanism provided on the outer wall of the base plate 1, the coil fixing mechanism including a rotating shaft 4 through and rotatably connected to the four corners of the base plate 1, a support rod 5 fixedly connected to the upper end face of multiple rotating shafts 4, a cavity 3 opened inside the base plate 1, a gear ring 7 rotatably connected to the inner wall of the cavity 3 through a bearing, and a gear 6 meshing with the gear ring 7 fixedly connected to the outer wall of multiple rotating shafts 4. A threaded rod 14 is rotatably connected to the inner wall of cavity 3, and a straight rack 8 that meshes with a toothed ring 7 is threadedly connected to the outer wall of the threaded rod 14. The upper and lower end faces of the straight rack 8 abut against the upper and lower sides of the inner wall of cavity 3, respectively.

[0020] In this embodiment: the coil is placed above multiple support rods 5. By rotating the threaded rod 14 with a handle, the threaded rod 14 drives the straight rack 8 to slide forward, which in turn drives the gear ring 7 to rotate clockwise. The gear ring 7 further drives multiple gears 6 to rotate counterclockwise, which in turn drives multiple rotating shafts 4 to rotate counterclockwise synchronously. The multiple rotating shafts 4 further drive multiple support rods 5 to rotate counterclockwise synchronously, so that the multiple support rods 5 move closer to each other synchronously, thereby fixing the coil. The entire structure of this utility model is made of plastic components, which avoids interference with the coil of the transient electromagnetic instrument. It can fix coils of transient electromagnetic instruments of different specifications, and has strong practicality.

[0021] As a technical optimization of this utility model, the base plate 1 includes an upper part 101 and a lower part 102. Multiple ear plates 103 are fixedly connected to the outer walls of both the upper part 101 and the lower part 102. Two ear plates 103 in the same vertical direction are detachably connected by bolts.

[0022] In this embodiment, the upper half 101 and the lower half 102 are detachably connected by fixing bolts, which facilitates the installation and maintenance of the device in the base plate 1.

[0023] As a technical optimization of this utility model, two support plates are fixedly connected to the four corners of the lower end face of the base plate 1, and rollers 9 are rotatably connected between the two support plates through a coupling shaft.

[0024] In this embodiment, by fixing the direction of movement of the roller 9, the coil is prevented from swinging left and right during the dragging process.

[0025] As a technical optimization of this utility model, the support rod 5 is L-shaped.

[0026] In this embodiment: by setting the support rod 5 to an L-shape, it is easier to fix the transient electromagnetic coil.

[0027] As a technical optimization of this utility model, a connecting seat 10 is provided on the front side of the upper end of the base plate 1, and a traction rod 11 is provided on the outer wall of the base plate 1. Both ends of the traction rod 11 are provided with pull ropes 12, and one end of the pull rope 12 is fixedly connected to the connecting seat 10.

[0028] In this embodiment, the device can be easily connected to a device that provides towing power (such as a car) via the tow bar 11 and the pull rope 12.

[0029] As a technical optimization of this utility model, the outer wall of the traction rod 11 is provided with multiple straps 13.

[0030] In this embodiment, multiple straps 13 are provided on the outer wall of the traction rod 11 to facilitate the fixing of various cables when the coil is working.

[0031] The working principle and usage process of this utility model are as follows: First, place the coil above multiple support rods 5. Then, rotate the threaded rod 14 by turning the handle. The threaded rod 14 drives the rack 8 to slide forward, which in turn drives the gear ring 7 to rotate clockwise. The gear ring 7 further drives multiple gears 6 to rotate counterclockwise, which in turn drives multiple rotating shafts 4 to rotate counterclockwise synchronously. The multiple rotating shafts 4 further drive multiple support rods 5 to rotate counterclockwise synchronously, causing the multiple support rods 5 to move closer to each other, thus fixing the coil. Next, connect the pull rope 12 at the front end of the traction rod 11 to a device that provides towing power (such as a car). The entire structure of this utility model is made of plastic components, avoiding interference with the transient electromagnetic instrument coil. It can fix transient electromagnetic instrument coils of different specifications, making it highly practical.
