The invention can quickly connect and release the drill rod, improve the working efficiency, reduce the labor intensity of workers and improve the safety factor of operation.
Specifically, the lifting rod 1 comprises a first cylindrical section, a second cylindrical section, a third cylindrical section and a fourth cylindrical section, the first cylindrical section, the second cylindrical section, the third cylindrical section and the fourth cylindrical section are sequentially connected into a whole from top to bottom, the diameter of the first cylindrical section is larger than that of the second cylindrical section, the diameter of the second cylindrical section is larger than that of the third cylindrical section, and the diameter of the third cylindrical section is larger than that of the fourth cylindrical section; the reset spring 2 is sleeved on the third cylindrical section, and the top end of the reset spring 2 is abutted against the edge of the second cylindrical section; the collapsible handle 4 is sleeved on the second cylindrical section and the third cylindrical section; the conical expansion head 3 is arranged on the fourth cylindrical section.
Specifically, the conical expansion head 3 is in threaded connection with the fourth cylindrical section.
Specifically, still include rings 7 and lifting rope 8, rings 7 one end is articulated with first cylinder section, and rings 7 other end is connected with lifting rope 8.
The working principle of the invention is as follows:
when a lifter needs to be plugged into a drill rod female buckle 6, a worker holds the expansion and contraction handle 4 tightly to compress the return spring 2 (the return spring 2 is sleeved on the lifting rod 1, the expansion and contraction handle 4 is arranged around the return spring 2, so that the bottom end of the return spring 2 is abutted against the expansion and contraction handle 4, the top end of the return spring 2 is abutted against the edge of the lifting rod 1 close to the top, namely the expansion and contraction handle 4 is lifted, the abutting part of the expansion and contraction handle 4 and the return spring 2 can extrude the bottom end of the return spring 2, the top end of the return spring 2 is abutted against the edge of the lifting rod 1 close to the top, namely the top end is fixed, so that the return 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 and contraction handle 4 through a bolt 9, and bolt 9 runs through horizontal chute 41, that is to say in the vertical direction, 4 vertical removal of harmomegathus handle, fixture block 5 also can follow vertical movement, and in the horizontal direction, fixture block 5 has a horizontal direction's removal because of the inclined plane influence of toper rising head 3, bolt 9 translation in horizontal chute 41 this moment), when 5 external screw thread major diameter of fixture block is less than 6 internal screw thread internal diameters of drilling rod box, can fill in drilling rod box 6, put into the back and hold, under reset spring 2's effect, harmomegathus handle 4 drives fixture block 5 and moves down and outwards expand along the inclined plane of toper rising head 3, the external screw thread major diameter grow of fixture block 5 is to embedding in 6 internal screw threads of drilling rod box, can promote the drilling rod. 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.
