Problems solved by technology
[0004] However, due to the deepness of geological drilling, the situation in the hole becomes more and more complicated, especially when the coal mine is drilling above the goaf for peeping operations, the broken rocks in the goaf often easily cause the drilling to be dislocated.
The existing lens can only move in the vertical direction. When the drilling hole is misplaced, the lens cannot avoid it, making the lens unable to continue to lower

The invention discloses a peep lens for geological drilling. The lens comprises a peep lens head, a peep lens tail and an angle adjusting device used for adjusting the relative angle of the peep lens head and the peep lens tail, the peep lens head is hinged to the peep lens tail, one end of the angle adjusting device is connected with the peep lens head, and the other end of the angle adjusting device is connected with the peep lens tail; and the angle adjusting device comprises a traction rope, a first guide wheel, a second guide wheel, a traction wheel and an angle adjusting driving mechanism, one end of the traction rope is fixed to one side of the lower end of the peep lens head, the other end of the traction rope sequentially passes through the first guide wheel, the traction wheel and the second guide wheel to be fixed to the other side of the lower end of the peep lens head, the middle of the traction rope is wound around the traction wheel, and the traction rope is wound around the traction wheel by at least one round. According to the lens, the front end of the peep lens for geological drilling can deflect, and when drilling dislocation occurs, the lens can avoid the dislocation, and peeping operation is completed.
Description
technical field [0001] The invention relates to the technical field of geological exploration, in particular to a geological drilling peeping lens. Background technique [0002] In the field of geological exploration technology, the purpose of constructing geological drilling is to ascertain the structure of the underground rock formation at the site, and to ascertain the lithology, thickness, and development of joints of each formation. There are two main methods: one is through drilling. The hole coring method is to sample underground rocks to the ground. In addition to visually observing the rocks, various physical properties of the rocks can also be measured through experiments. However, this method has cumbersome procedures, long coring time, and repeated lifting of the drill bit increases the possibility of drilling damage. The other is the method of borehole peeping, which uses camera imaging technology to present the conditions of the rocks around the hole through p...
