Embodiment Construction

[0027] specific implementation plan

[0028] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0029] This embodiment takes the holding and pulling probe rod as an example. In actual use, it is not limited to the probe rod, and other rod-shaped rod bodies are also applicable. Such as Figure 1 to Figure 3 As shown, a holding device includes a lifting rope 1, a shackle 2, an anti-slip block 4, a clamping block 5 and a holding member 6, and one end of the lifting rope 1 passes through the shackle 2 and one end of the clamping block 5 connected, the other end of the pull rope 1 is connected to the external pull mechanism, the pull mechanism is preferably a hoist or other lifting power device, and the pull mechanism generates a clamping block 5 through the pull rope 1 and the shackle 2. upward pull. The shackle 2 is detachably installed on one end of the clamping block 5, and the shackle 2 can be detachably in...

Abstract

The invention relates to a pulling device and a construction method. The pulling device includes a shackle and a clamping block. The shackle is installed at one end of the clamping block, and the other end of the clamping block away from the shackle is provided with a The groove has been passed; the groove is fixed with an anti-slip block, or the inner wall of the groove is provided with an anti-slip texture; the shackle is used to place the clamping block in one of the inclined state and the released state under the action of external force, so that the anti-slip Blocks or anti-slip lines generate friction on the rod body to keep the rod body in one of the fastening and loosening states. The present invention can well maintain the vertical state during disassembly and installation of the rod shape such as the probe rod, thereby effectively solving the problem of lifting and lifting the probe rod and improving operation safety.

Description

technical field [0001] The invention relates to the technical field of holding devices, in particular to a holding device and a construction method. Background technique [0002] In drilling or other technical fields, it is necessary to use rod-shaped accessories such as probe rods and drill pipes. These rod-shaped accessories usually have a certain weight and are usually in a vertical state under load and stress during use, and usually require Connect each probe rod or drill pipe end to end in sequence. For example, in ocean exploration, each probe rod is connected vertically end to end and penetrated into the seabed formation. Usually, the water depth of the ocean is greater than the length that the stability of the steel pressure rod of the probe rod can maintain without deformation. During the process, it is necessary to ensure that each probe rod is connected together and is in a vertical state without being too inclined. After the probe rod is connected to a certain l...
