Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline trepanning device technical field, especially an improved manual pipeline trepanning device. BACKGROUND

[0002] The manual trepanning device used in pipeline engineering at present needs manual operation when working, and the specific operation process is as follows: firstly, fix the trepanning device on the pipeline to be trepanned through the flange plate and other auxiliary equipment, then manually rotate the feed wheel, since the feed wheel and the wheel sleeve are integrated, the wheel sleeve moves downward through the thread between the outer wall of the wheel sleeve and the inner wall of the outer cylinder to make the rotary knife head at the lower end of the rotary rod contact the surface of the pipeline, then put the square hole in the middle of the ratchet wrench into the square sleeve head on the top of the rotary rod, manually rotate the handle of the ratchet wrench to cut the knife hole on the pipeline, then manually rotate the feed wheel to make the rotary knife closely contact the pipeline, and continue to rotate the handle of the wrench to cut; continuously repeat the process of rotating the handle of the wrench to cut and rotating the feed wheel to feed the knife, until the required hole is cut on the pipeline. Figure Three AND Figure Four The overall assembly state of the trepanning device.

[0003] In the working process, the worker determines the descending height of the rotary knife by experience, and the feeding degree of the knife is not accurate every time, so that the cutting process of the rotary knife will produce the result that the cutting depth is too small sometimes and too large sometimes, which will cause the cutting force and the cutting depth to be inconsistent every time the rotary knife is rotated, so that the trepanning process is not a uniform force cutting working process, for the soft pipe material (such as PVC), the deformation is too large if the knife is too deep, which will damage the pipeline, and it is difficult to feed the knife. For metal pipe material, if the feeding depth of the knife is too small, the cutting depth is too small, the efficiency is reduced, and if the feeding depth of the knife is too large, the cutting is not smooth, the deformation of the cutter and the pipeline is also large, and the efficiency is also reduced.
