Description

Technical Field

[0001] The utility model relates to the technical field of engineering exploration, in particular to a transceiver winch for cross-hole electromagnetic wave CT work. Background Art

[0002] The cross-hole electromagnetic wave CT method is an underground geophysical exploration method that uses radio waves to transmit and receive in two boreholes respectively, and determines the distribution of different underground media based on the strength of the received field at different positions. It is also called the in-well radio electromagnetic wave perspective method.

[0003] During use, the equipment is placed underground through connecting wires, and the underground structure is explored through imaging technology. During the lowering and taking out process, the equipment needs to be placed through a transceiver winch, which makes it easier for people to use it in this process. In order to ensure its effectiveness, some transceiver winches on the market are installed in the construction site, and they are fixed after finding the correct position.

[0004] However, when used for a long time, the wires connected to the CT machine are under stress for a long time, causing the overall length to become slightly longer than the original length, and the tension between the wires and the transceiver winch is reduced. At this time, when using the transceiver winch to reel in, the wound wires may easily become entangled or unwound, affecting the subsequent reeling of the transceiver winch. Utility Model Content

[0024] Working principle:

[0025] When using the utility model, since the CT instrument is winding the wire during operation, in order to ensure the stability and neatness of the wire winding, the position of the winding assembly 5 and the tension between the wires are manually checked before winding. If the tension is loose, the first screw 14 and the second screw 15 can be removed from the fixing frame 10 and the rotating plate 11 by a tool, and then the rotating plate 11 is manually rotated 90 degrees. The rotating plate 11 will drive the rotating shaft 12 at the lower end and the limiting rod 13 to rotate 90 degrees, so that the limiting rod 13 coincides with the second mounting groove 9, and then the rotating plate 11 is pulled upward again. When the whole moves up to contact with the fixing plate 7, the rotating plate 11 is rotated again to reset it. At this time, the limiting rod 13 is aligned with the first mounting groove 9. The mounting slots 8 overlap, and the rotating plate 11, the rotating shaft 12 and the limit rod 13 can be pulled out as a whole. After the equipment in the mounting plate 1 is not fixed, it can be moved according to the direction of adjustment required by people. When the tension is loose, the upper equipment is moved in the opposite direction. At this time, the fixed plate 7 moves in the mounting plate 1. After adjustment, the fixing frame 10 and the limit rod 13 can be installed again, and a plurality of second mounting slots 9 are provided in the mounting plate 1, which can facilitate the installation of the equipment at various parts of the mounting plate 1. After the adjustment is completed, the power supply of the motor 2 can be connected to the external power supply, and the motor 2 is started. The rotation of the motor 2 will change the speed and rotation direction through the reduction converter 3, and then the main shaft 4 will drive the winding component 5 and the wire to be wound.
