Method for removing blockage in bent pipeline in drawing mode

Abstract

The invention relates to a method for removing blockage in a bent pipeline in a drawing mode, which relates to a tool structure comprising: a pair of gripper arms (9) driven by a transition linkage mechanism and formed by a screw rod (8) and a gear (4) and arranged outward at one end of a metal snakeskin hose (5), and a handle (6) arranged at the other end of the metal snakeskin hose (5). Moreover a soft steel wire column (7) is connected in the metal snakeskin hose (5) between the transition linkage mechanism and the handle (6). The use method is simple. The tool of the invention is only pushed into the position of the pipeline blockage, the blockage (1) is easily gripped by the pair of gripper arms (9) which is directly driven by the transition linkage mechanism through the mode of rotation of the handle (6) (having an amplification action of hand power output), then the blockage (1) is clamped by anti-rotating the handle (6), then is pulled out, and the whole process of gripping the blockage in the bent pipeline is convenient and saves labour. The method of the invention is especially suitable for the general daily maintenance work associated with the pipeline (2) engineering.

Description

Technical field: [0001] The invention relates to a method for removing obstructions in curved pipelines by means of drawing. technical background: [0002] At present, the way to remove the blockage in the pipeline is to loosen the blockage and then discharge it from another outlet of the pipeline by pushing. If the pipeline does not have another outlet, or the other outlet is very far away, and there is no place for a large space pipe joint to get rid of the removal, then the above-mentioned pipeline obstruction is difficult to get rid of. [0003] People use a single-arm hook to hook the obstruction in the pipeline, which is also a short-distance (very close to the nozzle) method to pull the obstruction in the pipeline from the gate. However, due to the limitation of the pipeline space, in the narrow In the pipeline, because the single-arm hook is difficult to adjust to a suitable hooking position, the hooked obstruction is decoupled from the above-mentioned single-arm ho...

Problems solved by technology

If the pipe does not have another outlet, or if the other outlet is far away, and there is no place for a large space pipe joint to remove the clearing, then the above-mentioned pipe blockage is difficult to remove

[0003] People use a single-arm hook to hook the obstruction in the pipeline, which is also a short-distance (very close to the nozzle) method for pulling the obstruction in the pipeline from the gate. However, due to the limitation of the pipeline space, in the narrow In the pipeline, because the single-arm hook is difficult to adjust to a suitable hooking position, the hooked obstruction is decoupled from the above-mentioned single-arm hook during the hooking process, and it is difficult to achieve the purpose of removing the pipeline obstruction

[0004] CN2232943Y technology discloses a kind of technology that is more advanced than the above-mentioned method to remove pipeline blockage, and its main shortcoming is: in its use process, its pincers take out force to rely on the manual pulling force of human body to directly finish directly, do not have the following Smaller manual force input to complete the function of executing (replacing) larger pincer force output

This will inevitably bring inconvenience to the use
