Embodiment 1
[0034] like Figure 1 to Figure 7 Shown is an embodiment of a locking device for a salvage drilling core pipe of the present invention. A locking device for salvage drilling coring pipe, which includes a female joint assembly 3, a central shaft 4, a male joint assembly 2 and a tightening sleeve assembly 1, the tightening sleeve assembly 1 is fixedly connected with the male joint assembly 2, and the central shaft 4 One end is fixed inside the male joint assembly 2, and the other end of the central shaft 4 passes through the male joint assembly 2 and extends into the female joint assembly 3. The female joint assembly 3 is equipped with an automatic locking part for fixing the central shaft 4. The central shaft 4 The outer wall of the outer wall is sleeved with a movable first sleeve 5, and the male joint assembly 2 is provided with an adjustment member for adjusting the moving position of the first sleeve 5. The outer diameter of the end face of the first sleeve 5 close to the f...
Embodiment 2
[0042] An embodiment of a method for using a locking device for a salvage drilling core pipe. A method for using a locking device for a salvage drilling core pipe, comprising the following specific steps:
[0043] S1. One end of the female joint assembly 3 is connected to the core pipe in the drilling pipe. The clamping part 302 is opened in the shape of a claw. Fix the rope on the fastening sleeve 101 through the rope fastening bolt 103 on the ground, move the first sleeve 5 in the male joint assembly 2 upward to compress the spring 206, and clamp the guide bolt 207 on its outer wall to the inner sleeve 202 in the first extension groove 211, and then clamped in the arc-shaped guide groove 213 of the outer sleeve 201;
[0044] S2. Extend the male joint assembly 2 connected with the fastening sleeve 101 into the drilling pipe through a rope, and touch the end of the central shaft 4 to the rear end protrusion of the clamping piece 302, and the rear end of the clamping piece 302...
Embodiment 3
[0047] like Figure 8 Shown is an embodiment of a locking device for a salvage drilling core pipe. A locking device for a salvage drilling core tube is used to replace the core tube in a narrow drilling tube, specifically comprising the following steps:
[0048]S1. The guide bolt 207 on the first sleeve 5 moves along the toothed guide groove 210 of the inner sleeve 202 to the tooth groove near the inner end, and then rotates the outer sleeve 201 so that the second extension groove 203 of the outer sleeve 201 is aligned with the inner end. The first extension groove 211 of the casing 202 overlaps, and the rope is fixed on the fastening sleeve assembly 1 on the ground, and then the central shaft 4 is inserted into the female joint assembly 3 to complete the locking action, and the second cavity 306 of the female joint assembly 3 Connect the coring pipe that needs to be put into the ground;
[0049] S2. Lower this embodiment and the coring pipe connected to it into the drilling...
