Manufacturing process of irregular polygonal power transmission twin-limb tower connected by inner flanges
The invention discloses a manufacturing process of an irregular polygonal power transmission twin-limb tower connected by inner flanges, which comprises the following steps of: split type total splicing: respectively carrying out continuous total splicing on single-limb towers on a single-limb tower total splicing jig frame to complete section manufacturing; according to the characteristics of the cross sections of the segments, the largest straight edge on the outermost side is used as a bottom edge for overall splicing manufacturing; and integral pre-assembly is conducted, specifically, the manufactured single-limb tower sections are subjected to whole-tower-type pre-assembly on a double-limb tower integral pre-assembly jig frame, and a double-limb tower is placed and pre-assembled according to the real tower position state. According to the method, the double-limb tower is reasonably segmented and blocked, the special total assembling jig frame is adopted for split type total assembling to manufacture the single-limb tower sections, and finally the double-limb tower is integrally pre-assembled on the special integral pre-assembling jig frame. Meanwhile, the irregular polygonal power transmission double-limb tower connected with the inner flanges is manufactured by setting a reasonable assembly sequence, a reasonable technological process and other measures, and the manufacturing problem of the irregular polygonal power transmission double-limb tower connected with the inner flanges is effectively solved; and the design precision is ensured.
本发明公开了一种内法兰连接的不规则多边形输电双肢塔制造工艺，包括：分体式总拼：将单肢塔分别在单肢塔总拼胎架上进行连续总拼，完成节段制造；根据节段横截面特点，以最外侧的最大直边为底边进行总拼制作；整体式预拼：将制造完成的单肢塔节段在双肢塔整体预拼胎架上进行整塔式预拼装，双肢塔按照实塔位态进行摆放及预拼。本发明通过对双肢塔进行合理的分段和分块，采用专用总拼胎架进行分体式总拼制作单肢塔节段，最后在专用整体预拼装胎架上进行双肢塔整体式预拼装，同时通过设置合理的组装顺序、工艺流程等措施实现内法兰连接的不规则多边形输电双肢塔的制造，有效地解决了内法兰连接的不规则多边形输电双肢塔的制造难题；保证了设计精度。
