Further preferably, the orientation of the two first gaps 101 is vertically distributed at 90 degrees, and when the telescopic cylinder 5 extends and contracts, the two jaws 4 simultaneously clamp and release, so when the first jaw 4 rotates to the push beam rod changing station, the telescopic cylinder 5 contracts, the first jaw 4 releases for rod changing, at the moment, the second jaw 4 is also in an open state, the second jaw 4 is in a horizontal vertical state above the first jaw 4, a drill rod in the second jaw 4 cannot fall off, and the orientation of the two first gaps 101 is vertically distributed at 90 degrees, so that the two jaws 4 can be prevented from opening simultaneously to cause the drill rod to fall off.
In a preferred embodiment, wear-resistant blocks 8 are detachably disposed on the inner clamping plate 1 and the outer clamping plate 2 at positions corresponding to the first notch 101 and the second notch 201, and the first notch 101 and the second notch 201 are disposed on the corresponding wear-resistant blocks 8, respectively. Wear-resisting piece 8 is made by metal material, through including cardboard 1, outer cardboard 2 on set up modular wear-resisting piece 8, and then can match the drilling rod of different diameters, can be through the drilling rod of the different diameters of wear-resisting piece 8 adaptation of changing first breach 101, second breach 201 department, wear-resisting piece 8 is the simple change convenience of assembled maintenance. Meanwhile, the friction force between the jaw 4 and the drill rod can be increased by the wear-resistant block 8, and the fixing strength of the drill rod is guaranteed.
In this embodiment, the wear-resistant block 8 is detachably connected with the inner clamping plate 1 and the outer clamping plate 2 in a gluing or clamping or bolt connection manner. Preferably, the wear-resistant sleeve is configured as a plate-shaped, block-shaped or strip-shaped structure with one end being wide and the other end being narrow, for example, the wear-resistant sleeve is configured as a trapezoid block-shaped structure, and the first notch 101 and the second notch 201 are configured at the narrow end of the wear-resistant sleeve. Meanwhile, the same trapezoid structure grooves 9 are formed in the positions, corresponding to the wear-resistant sleeves, of the inner clamping plate 1 and the outer clamping plate 2, the wear-resistant sleeves are directly clamped in the corresponding trapezoid structure grooves 9 during assembly, the wear-resistant sleeves cannot fall out easily and are convenient to disassemble and replace, and maintenance cost is reduced. Of course, on the basis of clamping, the clamping can be further fixed by being matched with hinge or bolt connection. For example, the wear-resistant block 8 and the trapezoidal structural groove 9 are fixed by gluing on the matching surface.
In this embodiment, the inner clamping plate 1 is rotatably sleeved on the central shaft 3 in a bearing connection or clearance fit manner. Taking bearing connection as an example, namely, the inner clamping plate 1 is connected with the central shaft 3 through a bearing, the inner ring of the bearing is fixedly connected with the central shaft 3 in a key connection or welding or interference fit manner, the inner clamping plate 1 is provided with a first through hole 102, and the hole wall of the first through hole 102 is fixedly connected with the outer ring of the bearing in a key connection or welding or interference fit manner.
