Large-caliber plastic pipeline trepanning equipment

Abstract

The invention provides large-caliber plastic pipeline trepanning equipment which comprises a pair of clamping devices, a supporting device and a trepanning device. The trepanning device is fixed to the supporting device. The clamping devices penetrate the supporting device and make the supporting device fixed to the outer wall of a pipeline. On the premise that no extra equipment is additionally arranged, the requirements of plastic pipelines of various specifications for trepanning construction can be met, the trepanning angle and the trepanning size of the equipment can be flexibly adjusted on the site, and adaptability is high; in the equipment trepanning operation process, rigidity is good, the trepanned shape of the pipeline is regular, the trepanning accuracy of the pipeline is high, and complex manual grinding operation is avoided; the contact faces between the clamping devices and the outer wall of the pipeline are large, so that damage caused by construction to the outer surface of the pipeline is small; and the overall trepanning operation is convenient and fast, labor intensity is relieved, and work efficiency is improved.

Description

technical field [0001] The invention relates to a large-diameter plastic pipeline drilling equipment, which belongs to the technical field of pipeline construction equipment. Background technique [0002] With the continuous research and development of new plastic materials and new processes, the plastic pipe industry has also ushered in new development opportunities. Some large-diameter and super-large-diameter plastic pipes have gradually entered the market due to their advantages that traditional metal and concrete pipes do not have. The market and applications are becoming more and more extensive. During the construction, installation or renovation of the pipeline network, it is often necessary to drill holes in the pipeline wall. Unlike the metal pipeline drilling method, the on-site drilling operation of plastic pipelines, especially large-diameter plastic pipelines, is more difficult. At present, the common method of opening large-diameter plastic pipes is to first m...

Problems solved by technology

At present, the common method of opening large-diameter plastic pipes is to first mark the intersecting line on the corresponding position on the pipe wall, and then manually use a cutting saw to cut out a rough shape along the intersecting line, and then use grinding equipment, manual grinding, and fine trimming On the edge of the hole, the operation is difficult, the construction steps are cumbersome, the operator's labor intensity is high, the hole precision is low, the construction efficiency is low, and the quality of the pipe connection is also affected. This is the difficulty faced in the current large-diameter plastic pipe hole construction.
