Two ends of the middle circular ring 120 are respectively welded with the upper circular ring 110 and the lower circular ring 130; the upper circular ring 110 is sleeved on the output shaft 300 of the jumbolter and is in threaded connection with the output shaft 300 of the jumbolter; the side wall of the middle circular ring 120 is provided with a first notch 121, the lower circular ring 130 is provided with a first bulge 131, the first bulge 131 and the side wall of the first notch 121 enclose a first clamping groove 140, the lower end of the first clamping groove 140 is provided with a lower circular ring 130 for sealing, and the first-stage lifting lug 410 is clamped in the first clamping groove 140, so that the first connecting mechanism 100 can drive the first drill rod 400 to rotate.

Specifically, the middle ring 120 is configured as two semicircular rings, and a gap between the semicircular rings is the first notch 121, as shown in fig. 4. The inner wall of the lower ring 130 is provided with a second notch 132, and the primary lifting lug 410 can pass through the second notch 132 along the axial direction of the first drill rod 400 so as to ensure that the primary lifting lug 410 can enter the first clamping groove 140. In this embodiment, the lower ring 130 is composed of two semicircular rings and two arc steel bars, and the arc steel bars and the semicircular rings are arranged at intervals to form a complete circle, so that the strength of the first connecting mechanism 100 is ensured to transmit torque, and the arc steel bars are close to the outer side surface of the ring to form the second notch 132.

Because the drill rod is in threaded connection with the drill rod and the drill rod is in threaded connection with the output shaft 300 of the jumbolter, in order to ensure that the first connecting mechanism 100 is reliably connected with the output shaft 300 to realize the disassembly of the threaded connection between the drill rods, the upper circular ring 110 is provided with a first connecting lug 111, the output shaft 300 is provided with a second connecting lug 310, the first connecting lug 111 is provided with a first connecting hole, and the second connecting lug 310 is provided with a second connecting hole.

In this embodiment, the second connection mechanism 200 includes a left flap assembly 210 and a right flap assembly 220, and the left flap assembly 210 and the right flap assembly 220 are structurally symmetrical, as shown in fig. 7 and 8. Taking the left turning plate assembly 210 as an example for illustration, the left turning plate assembly 210 comprises a connecting seat 211, a baffle 212 and a handle 213, wherein the connecting seat 211 is welded with the jumbolter, one end of the baffle 212 is hinged to the connecting seat 211, the other end of the baffle 212 is provided with an arc groove 21a, and the handle 213 is connected with the baffle 212 so as to turn over the baffle 212. Specifically, the circular arc grooves 21a on the two baffles 212 form a rod penetrating hole 230, and the drill rod is inserted into the rod penetrating hole 230. The inner wall of the arc groove 21a is provided with a second clamping groove 240, and the second lifting lug 420 is clamped with the clamping groove to fix the second drill rod 500.

In this embodiment, the second clamping groove 240 is a non-through groove, specifically, the second drill rod 500 is inserted into the rod penetrating hole 230, and the second drill rod 500 cannot continue moving after the second lifting lug 420 is clamped in the second clamping groove 240, so that the baffle 212 is limited by the second drill rod 500, and the second lifting lug 420 is prevented from falling out of the second clamping groove 240 under the influence of factors such as vibration. Wherein the connection seat 211 can block the baffle 212 to prevent the baffle 212 from swinging downwards, and the second drill rod 500 can block the baffle 212 to prevent the baffle from swinging upwards; that is, the baffle 212 is kept in a horizontal state by the cooperation of the connecting seat 211 and the second drill rod 500, so that the second clamping groove 240 and the second lifting lug 420 are prevented from being separated due to the vibration of the baffle 212, and the smooth disassembly is ensured.

In an alternative of this embodiment, the left panel turnover assembly 210 further includes a reinforcing plate 214, and the baffle 212 is provided with an arc slot 21a, but not provided with a second clamping slot 240; the reinforcing plate 214 is provided with an arc groove 21a similar to the baffle 212, and the second clamping groove 240 is provided on the reinforcing plate 214. That is, the secondary lifting lug 420 is clamped in the second clamping groove 240 and abuts against the baffle 212, as shown in fig. 8.

The working process of the dismounting device for the recovered drill rod of the jumbolter, provided by the embodiment, is as follows:

when the drill rod is disassembled, the output shaft 300 of the jumbolter is firstly separated from the first drill rod 400, and the output shaft 300 is far away from the first drill rod 400 through the lifting function of the jumbolter. The first coupling mechanism 100 is then coupled to the output shaft 300 and the coupling pin 600 is installed so that the first coupling mechanism 100 is integrated with the output shaft 300, preventing the first coupling mechanism 100 from loosening during the disassembly of the drill rod. The jumbolter then descends the output shaft 300, simultaneously drives the first connecting mechanism 100 to descend, and in the descending process, the output shaft 300 drives the first connecting mechanism 100 to rotate by a certain angle after the primary lifting lug 410 passes through the second notch 132, so that the primary lifting lug 410 is aligned with the first clamping groove 140, and then the jumbolter ascends the output shaft 300 so that the lifting lug is clamped into the first clamping groove 140. At this time, the second lifting lug 420 connected with the first drill rod 400 and the second drill rod 500 is just clamped in the second clamping groove 240, and the first drill rod 400 and the second drill rod 500 are relatively rotated under the drive of the output shaft 300 by limiting the second drill rod 500 through the second clamping groove 240, so that the two drill rods are easily separated.

It should be noted that, when the jumbolter works normally, the baffle 212 is opened to enable the drill rod to lift normally, so as to avoid the interference of the second clamping groove 240 on the axial movement of the drill rod. When the drill rod is required to be disassembled, the baffle 212 is swung to a horizontal state to form the rod through hole 230.

In an alternative to this embodiment, the second coupling mechanism 200 may be provided in sliding connection with the jumbolter, i.e. the second coupling mechanism 200 may be moved in a vertical direction to match drill rods of different lengths. The sliding connection mode can be limited and driven by a mode of adding a lead screw to a guide rail, and the connection mode is of a common structure and is not described herein.
