Specifically, the lifting device further comprises a lifting ring 7 and a lifting rope 8, wherein one end of the lifting ring 7 is hinged to the first cylindrical section, and the other end of the lifting ring 7 is connected with the lifting rope 8.
The working principle of the invention is as follows:
when the lifter is to be plugged into the drill rod box 6, a worker tightly holds the expansion and contraction handle 4, compresses the reset spring 2 (the reset spring 2 is sleeved on the lifting rod 1, the expansion and contraction handle 4 is surrounded on the reset spring 2, so that the bottom end of the reset spring 2 is abutted to the expansion and contraction handle 4, the top end of the reset spring 2 is abutted to the top edge of the lifting rod 1, namely the expansion and contraction handle 4 is lifted, the abutting part of the expansion and contraction handle 4 and the reset spring 2 can extrude the bottom end of the reset spring 2, and the top end of the reset spring 2 is abutted to the top edge of the lifting rod 1, namely the top end is fixed, so that the reset spring 2 is compressed), and simultaneously drives the fixture block 5 to move upwards along the inclined plane of the conical expansion head 3 (the embedded slide block of the fixture block 5 is embedded in the slide strip groove of the conical expansion head 3, namely the fixture block 5 can slide along the inclined plane of the conical expansion head 3; the top of the fixture block 5 is connected with the expansion handle 4 through the bolt 9, and the bolt 9 runs through the horizontal chute 41, that is, in the vertical direction, the expansion handle 4 moves vertically, the fixture block 5 can also move vertically, and in the horizontal direction, the fixture block 5 is influenced by the inclined plane of the conical expansion head 3, there is a horizontal direction movement, at the moment, the bolt 9 moves horizontally in the horizontal chute 41), until the external thread diameter of the fixture block 5 is smaller than the internal thread diameter of the drill rod box 6, the interior of the drill rod box 6 can be plugged in, the hand is put in after plugging in, under the action of the reset spring 2, the expansion handle 4 drives the fixture block 5 to move downwards and expand outwards along the inclined plane of the conical expansion head 3, the external thread diameter of the fixture block 5 is enlarged to the internal thread of the embedded drill rod box 6, and the drill rod can be lifted. The lifter is taken down, the lifter is operated in the same way, and a worker can take down the lifter by holding the expansion and contraction handle 4 tightly (because the fixture block 5 slides along the inclined plane of the conical expansion head 3, the lifter is taken down, namely the fixture block 5 slides towards the vertex angle of the triangle, the position of the fixture block 5 is changed and gradually draws close inwards, so that the separation of the external thread of the fixture block 5 and the internal thread of the drill rod female buckle 6 is realized, when the lifter is put in, the fixture block 5 slides towards the bottom of the triangle, the position of the fixture block 5 is changed and gradually expands outwards, and the external thread of the fixture block 5 is embedded into the internal thread of the drill rod female buckle 6);
when the lifting rod is lifted, the lifting ring 7, the lifting rod 1 and the conical expansion head 3 are integrated, the thread of the female drill rod buckle is meshed with the thread of the fixture block 5, the fixture block 5 is pulled by gravity to move downwards, meanwhile, the fixture block 5 is influenced by the inclined plane of the conical expansion head 3 and tends to expand outwards, so that the external thread of the fixture block 5 is more tightly meshed with the thread of the female drill rod buckle, the heavier the drill rod is, the tighter the meshing is, and the situation that the drill rod is not released is ensured; when the lifter is taken down, the drill rod falls to the ground, the gravity does not enable the clamping block 5 to tightly engage with the drill rod box any more, and a worker also operates the expansion and contraction handle 4 tightly, so that the lifter can be taken out when the thread of the clamping block 5 is contracted to be smaller than the thread of the drill rod box in the large diameter.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
