Description
技术领域technical field
本发明属于输电线路压接管压接工艺控制检测技术领域，具体涉及一种输电线路压接管弯曲度测量专用工具。The invention belongs to the technical field of crimping process control and detection of crimping tubes of power transmission lines, and in particular relates to a special tool for measuring the bending degree of crimping tubes of power transmission lines.
背景技术Background technique
输电线路导地线接头连接均采用压接管液压连接，在压接过程中，如果液压时所使用的压模与压接管不匹配，或者在压接时导地线与压接管未保持水平状态，未与液压机轴心相一致，就会导致压接管受压后产生弯曲。一般情况下，压模宽度越窄，压接的模数越多，弯曲度就越大，弯曲变形小于2%范围内的可视变形应校直，变形等于或大于2%或调直出现裂纹的均应重新压接。The joints of the transmission line conductors and ground wires are all connected hydraulically with crimping tubes. During the crimping process, if the die used in the hydraulic pressure does not match the crimping tubes, or the grounding wires and the crimping tubes are not kept horizontal during crimping, If it is not consistent with the axis of the hydraulic press, it will cause the crimping tube to bend after being pressed. In general, the narrower the width of the die, the more the modulus of the crimp, and the greater the curvature. The visible deformation within the range of bending deformation less than 2% should be straightened, and the deformation is equal to or greater than 2% or cracks appear in straightening should be re-crimped.
但是，目前在施工中还是用水平仪加直尺或卷尺测量，甚至还是目测的方法判断压接管压后的弯曲量，没有一种用于压接管弯曲度测量的专用工具，所以压接管的压接工艺很难控制。However, at present, in construction, a spirit level plus a ruler or a tape measure is used to measure, or even a visual method to judge the bending amount of the crimped tube after compression. There is no special tool for measuring the bending degree of the crimped tube, so the crimping of the crimped tube The process is difficult to control.
为了能够准确测量出输电线路压接管弯曲度，确保输电线路压接管压后满足《输变电工程架空导线及地线液压压接工艺规程》DL/T 5285的规定：压接后的压接管不应有扭曲变形，其弯曲变形应小于压接管长度的2% ，且有明显弯曲变形时应校直，校直过程中不应出现裂纹或应力集中，否则应重新压接。特发明一种用于输电线路压接管弯曲度测量的专用工具。In order to accurately measure the bending degree of the crimping tube of the transmission line, ensure that the crimping tube of the transmission line meets the regulations of DL/T 5285 in the "Hydraulic Crimping Process Regulations for Overhead Conductors and Ground Wires of Power Transmission and Transformation Engineering": the crimping tube after crimping is not There should be distortion and deformation, and the bending deformation should be less than 2% of the length of the crimping tube. If there is obvious bending deformation, it should be straightened. There should be no cracks or stress concentration during the straightening process, otherwise it should be crimped again. A special tool for measuring the bending degree of crimping tubes of transmission lines is specially invented.
