Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The following description is only for the purpose of explanation and is not intended to limit the invention.
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model relates to a drill rod fishing device, including drill rod base member 1 and a location section of thick bamboo 2, drill rod base member 1 includes the screw thread nose bar 102 that body of rod 101 and body of rod 101 front end extend, and body of rod 101 afterbody is equipped with the corresponding internal thread hole 103 with screw thread nose bar 102 shape and size, and body of rod 101 stretches into in a location section of thick bamboo 2 and with a location section of thick bamboo 2 rigid coupling from a location section of thick bamboo 2 rear end, and the at least part of through-hole is toper hole 201 in a location section of thick bamboo 2, and the one end aperture that body of rod 101 was kept away from to this toper hole 201 is greater than its aperture that is close body of rod 101 one end, a location section of thick bamboo 2 rear end is equipped with strengthening rib 3, this strengthening rib 3 and body of rod 101 and a location section of thick bamboo 2 rigid coupling.
The distribution and the quantity of strengthening rib 3 are decided according to conditions such as operating condition needs and drilling rod size, for example, as optimization scheme, strengthening rib 3 is at body of rod 101 outside circumference evenly distributed, and 3 quantity of strengthening rib can be 3 ~ 5.
As to the through hole in the positioning cylinder 2, there may be different options, that is, the front portion (the portion far away from the rod 101) of the through hole in the positioning cylinder 2 is a tapered inner hole 201, while the shape of the rear portion (the portion sleeved with the rod 101) of the through hole in the positioning cylinder 2 is not limited, wherein as an embodiment, the inner hole at the rear end of the positioning cylinder 2 may be a cylindrical inner hole with a uniform diameter, which is sleeved on the front end of the rod 101 and fixedly connected with the front end of the rod 101. As another embodiment, the through hole in the rear portion of the positioning cylinder 2 may have a small taper (small change of the aperture), and then when the front end of the rod 101 extends into the rear portion of the positioning cylinder 2, the positioning cylinder 2 and the rod 101 are fixed by a conventional technique.
