Abstract

The invention belongs to the technical field of MPP (modified polypropylene) power cable protective tubes and particularly relates to an MPP power cable protective tube thread machining device. The MPP power cable protective tube thread machining device comprises a bottom plate, two parallel supporting plates and a limiting plate are fixedly connected to the upper end of the bottom plate, a rotating pipe is arranged above the bottom plate, a fixing ring is rotatably connected to the rotating pipe, the lower sidewall of the fixing ring is fixedly connected to the upper end of the left supporting plate, two fixing plates are arranged in the rotating pipe, an adjusting block is fixedly connected to the outer side of a rotating ring, a first adjusting mechanism for adjusting the two fixing plates is arranged in the adjusting block, a rotating shaft is rotatably connected between the two supporting plates, a gear is fixedly connected to the rotating shaft coaxially, and tooth spaces meshingwith the gear are formed on the outer sidewall of the rotating pipe. The MPP power cable protective tube thread machining device is capable of reducing loss of turning tools and protecting MPP tubesfrom deforming during thread machining so as to make a thread more accurate.

Description

technical field [0001] The invention belongs to the technical field of MPP power cable protection pipes, and in particular relates to a thread processing device for MPP power cable protection pipes. Background technique [0002] MPP uses modified polypropylene as the main raw material. It does not require a lot of dredging, excavation and damage to the road surface. It is not necessary to lay pipes, cables and other construction projects in special areas such as roads, railways, buildings, and river beds. Compared with the pipe method, the trenchless power pipe project is more suitable for the current environmental protection requirements, and removes the dust, traffic congestion and other disturbing factors caused by traditional construction. This technology can also be laid in some areas where excavation operations cannot be implemented. Pipelines, such as historic sites, downtown areas, crop and farmland protection areas, highways, rivers, etc. [0003] When threading th...
