Embodiment Construction
[0027] specific implementation
[0028] Below, in conjunction with the accompanying drawings and specific embodiments, the present invention is further described:
[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. like Figure 1 to Figure 3 As shown, a holding and pulling device includes a lifting rope 1, a shackle 2, an anti-skid block 4, a clamping block 5 and a holding member 6. One end of the pulling rope 1 passes through the shackle 2 and one end of the clamping block 5. Connection, the other end of the pulling rope 1 is connected with an external pulling mechanism, the pulling mechanism is preferably a hoisting hoist or other lifting power device, and the pulling mechanism generates a clamping block 5 through the pulling rope 1 and the shackle 2. upward pull. The shackle 2 is detachably installed at one end of the clamping block 5, and t...

The invention relates to a holding and pulling device and a construction method. The clasping and pulling device comprises a shackle and a clamping block, the shackle is installed at one end of the clamping block, and the other end, away from the shackle, of the clamping block is provided with a groove for a rod body to penetrate through; anti-skid blocks are fixedly arranged in the grooves, or anti-skid lines are arranged on the inner walls of the grooves; and the shackle is used for enabling the clamping block to be in one of an inclined state and a de-inclined state under the action of external force, so that the anti-skid block or the anti-skid lines generate friction force on the rod body to enable the rod body to be in one of a fastened state and a loosened state. According to the device, the rod-shaped feeler lever and the like can be well kept in a vertical state in the dismounting and mounting process, so that the problem of holding and lifting of the feeler lever can be effectively solved, and the operation safety is improved.
Description
technical field [0001] The invention relates to the technical field of holding and pulling devices, in particular to a holding and pulling device and a construction method. Background technique [0002] In drilling or other technical fields, rod-shaped accessories such as probe rods and drill rods need to be used. These rod-shaped accessories usually have a certain weight and are usually in a vertical state with load and force during use, and usually require Connect the probe rods or drill rods end to end in sequence. For example, in marine exploration, each probe rod is vertically connected end to end and driven into the seabed strata. Usually, the water depth of the ocean is greater than the length that the stability of the probe rod steel pressure rod can maintain without deformation, so when the probe rod is driven into the marine stratum During the process, it is necessary to ensure that each probe rod is connected together and is in a vertical state without being too ...
