The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, fig. 1 is a schematic structural view of a ball-clip type wire-line core drill according to an embodiment of the present invention.

In the embodiment, the ball clamp type rope core drilling tool comprises a drill rod 1, a fishing spear seat 2, a spear seat tube 3, a spring baffle 4, a compression spring 5 and a ball clamp limiting 6 which are arranged in the drill rod 1, steel ball 7, the ball seat 8, the ball frame 9, suspension ring 10 and seat ring 11, drag for lance seat 2 and set up in lance seat pipe 3, ball frame 9 includes ball frame head end 12 and ball frame pole 13, ball frame head end 12 is connected with connecting seat 14, seat ring 11 is installed on the inner wall of the drilling rod 1 that corresponds connecting seat 14 department, suspension ring 10 sets up outside connecting seat 14 and is located seat ring 11 and is close to one side of dragging for lance seat 2, the ball seat 8 cover is located outside ball frame head end 12, the clearance has between ball seat 8 and the ball frame pole 13, install the steel ball 7 that can be along radial activity on the ball seat 8, the spacing 6 of ball card can be followed ball frame pole 13 activity ground and is located outside ball frame pole 13, the spacing 6 one end towards ball frame 9 head end of ball card is the toper structure.

Threaded hole is seted up to the tip of hack lever 13, the last fixed orifices that has seted up of spring baffle 4, fixing bolt 15 passes the fixed orifices and locks the tip of being fixed in hack lever 13 with spring baffle 4 in the threaded hole, install compression spring 5 between spacing 6 of ball card and the spring baffle 6, the inner wall of drilling rod 1 has and is used for 7 spacing grooves 16 to the steel ball, rectangular hole 17 has been seted up along its axial on the hack lever 13, wear to be equipped with first connecting pin 18 in the rectangular hole 17, the both ends of first connecting pin 18 are connected as an organic whole with spear seat pipe 3 and the spacing 6 of ball card. The ball seat 8 and the head end 12 of the ball holder are connected into a whole through a second connecting pin 19.

The working principle of the ball clamp type rope coring drilling tool is as follows:

the first stage is as follows: in the inner pipe throwing stage, in the using process of the rope core drill, the inner pipe assembly needs to be thrown to the outer pipe assembly at the bottom of the hole through the drill rod. In the process, the compression spring 5 applies a downward force to the ball retainer 6, so that the end slope of the ball retainer 6 applies a downward and outward force to the steel ball 7, and the steel ball 7 is in contact with the inner wall of the drill rod 1. Due to the shape and high hardness of the steel ball 7, the steel ball 7 is in continuous contact with the inner wall of the drill rod 1 in the throwing process of the inner pipe assembly, so that the descending speed of the inner pipe assembly can be effectively reduced, and the inner pipe assembly is protected.

And a second stage: after the inner tube assembly is dropped into position, the suspension ring 10 sits on top of the seat ring 11. At the moment, the steel ball 7 just reaches the limiting groove 16 on the inner wall of the drill rod, and under the action of downward and outward force applied to the steel ball 7 by the ball clamp limiting 6, the steel ball 7 enters the limiting groove 16, so that the inner pipe assembly is fixed, and then drilling is started.

And a third stage: in the salvaging stage, after the drilling process is finished, the inner pipe assembly needs to be lifted to the hole opening by using a salvaging device. The fishing hook hooks the fishing spearhead after the fisher is thrown in the hole and reaches the bottom of the hole. The steel wire rope of connecting the fisher upwards stimulates, drives spear seat pipe 3 upwards, and ball card spacing 6 is also upwards by the pulling this moment, and in the clearance between ball seat 8 and the ball frame pole 13 was fallen to steel ball 7, the fixed of inner tube assembly and outer tube assembly was relieved, and the inner tube assembly was pulled out the drill way.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
