Automatic bending machine for wire-pulling elbow for electric transmission line pole tower

Abstract

The invention provides an automatic bending machine for a wire-pulling elbow for an electric transmission line pole tower. The automatic bending machine comprises a case, a reinforcing cushion plate fixedly arranged on the case, a limiting and fastening mechanism which is fixedly arranged on the case and the reinforcing cushion plate for fastening and limiting a to-be-bent steel strand for manufacturing the wire-pulling elbow, a bending mechanism which can be movably arranged on the reinforcing base plate for bending the to-be-bent steel strand for manufacturing the wire-pulling elbow, and a circuit device which is used for driving the bending mechanism to act. When the automatic bending machine is used, the wire-pulling elbow which is needed for automatically bending does not need to be manually bent, so that time and labor are saved, and working efficiency can be greatly improved; bending radian precision of the wire-pulling elbow can be greatly improved in comparison with bending radian precision in the prior art; and moreover, the automatic bending machine is good in safety in use, is strong in applicability, is easy to transport and carry, and is suitable for outdoor operationof the power supply department.

Description

technical field [0001] The invention relates to a power transmission line construction auxiliary tool, in particular to an automatic bending machine for power line pole, tower, and stay wire elbows. Background technique [0002] Guyed pole towers are widely used in the construction of electric power overhead lines, and guyed wires are the main components to keep them stable. The guy wires of overhead power line towers usually consist of 7 parts: guy reels, guy wire U-shaped rings, guy rods, UT-shaped wire clamps, steel strands, wedge-shaped wire clamp handles, and guy wire hoops (hanging points on poles). The main process of cable production is the production of cable handles and bottom handles. Among them, the core step that consumes the most time and has the highest quality requirements is the production of cable elbows. The traditional method of making guyed elbows is generally made by hand using simple auxiliary tools such as wrenches on the construction site. Too larg...

Problems solved by technology

The traditional method of making guyed elbows is generally made by hand using simple auxiliary tools such as wrenches on the construction site. Too large or too small will lead to too large gap when installing the cable elbow, the quality is not up to standard, and then lead to waste of materials; Large, it is necessary to repeatedly bend the steel strands when manually making the cable elbows, which takes a long time and wastes manpower; third, when bending the steel strands, it is easy to cause safety accidents caused by steel strands springing back and hurting people

For example, the Chinese patent document whose application publication number is CN103560434A and whose name is "pull wire elbow power tool" discloses an auxiliary tool that uses the principle of leverage to save effort to make a guy wire elbow; The Chinese patent document "Elbow Booster", which discloses another auxiliary tool that uses the principle of leverage to save effort to make a guyed elbow; although the above-mentioned tool can improve the shortcomings of the traditional method of making a guyed elbow to a certain extent, but two Those who still exist: the need for manpower, the production accuracy is not easy to control, and the problem of time-consuming
