Title:
PIPELINE BEND MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/000649
Kind Code:
A1
Abstract:
A pipeline bend measurement device, comprising: a first housing (100), the exterior thereof being provided with a plurality of rollers (110) and the first housing (100) being connected to a traction component (120) outside of the first housing (100); a second housing (200), arranged in the first housing (100) and rotatably connected to the first housing (100); an inertia assembly (300), arranged in the second housing (200) and used for maintaining the spatial angle of the second housing (200) unchanged, the inertia assembly (300) comprising an inertia wheel (310) and a motor (320) for driving the inertia wheel (310) to rotate; and a photoelectric sensor (400), arranged between the first housing (100) and the second housing (200) and used for measuring the angle of rotation of the first housing (100) relative to the second housing (200). The pipeline bend measurement device may be used to measure the angle and length of a sounding pipe and does not need to enter a cabin along the piping to measure the sounding pipe, thereby reducing workload and risk factors which may possibly appear in the measurement and improving work efficiency and economic benefits. The pipeline bend measuring device has the advantages of simple structure, fewer parts, convenient use and simple maintenance.
