[0002] Drilling rigs are important equipment widely used in oil exploration, geological surveys, mining, construction engineering and other fields. With the continuous development of technology, the drilling depth of drilling rigs is also constantly deepening. A single drill rod can no longer meet the drilling depth, so multiple drill rods are required to work together. During operation, drill rods need to be frequently replaced manually using hydraulic wrenches, which is labor-intensive. In addition, it is inconvenient to replace drill rods in a vertical construction state, which greatly affects the efficiency of drilling construction.

[0003] Therefore, the traditional drilling rig rod unloading device is no longer fully applicable to the current drilling rig. Summary of the Invention

The telescopic cylinders arranged symmetrically at both ends are connected to the caliper seat at one end and to the caliper tongue at the other end. The extension and retraction of the cylinders can drive the movement of the caliper tongue.

[0057] 2. A round tube is welded to the bottom of the caliper seat, which is inserted into the round hole of the drilling platform so that the caliper can rotate in the round hole.

[0058] 3. The centering sleeve is embedded in the circular tube of the caliper. The centering sleeve can effectively prevent the shaking of the drill rod during drilling, and also reduce the wear of the drill rod and the caliper.

[0059] 4. The blocks are welded on the drilling platform and distributed at a certain angle on the left and right sides of the caliper. When the caliper rotates, the side of the caliper fits perfectly with the side of the block.

[0060] 5. There is a flat cut at the end of the drill rod. Driven by the telescopic cylinder, the caliper tongue can be stuck in the flat cut of the drill rod, so that the caliper and the drill rod are tightly clamped together. At this time, the power head rotates in the opposite direction, which will drive the drill rod and the caliper to rotate in the opposite direction together. When the caliper rotates, it will collide with the block on the drilling platform. Under the action of the impact force, the drill rod thread will loosen, and the power head will continue to rotate in the opposite direction, and the drill rod will be removed.
