Abstract
The utility model discloses a weld holder for fillet welding in a flat position of a tower leg of an electric transmission line iron tower. The weld holder comprises a base. A lifter is installed in the middle of one side of the upper surface of the base. Two guide posts are symmetrically installed upward on positions, on two sides of the lifter, of the base. A cover plate which is tilted by 15-25 degrees is installed on the upper surface of a telescopic contact of the lifter and the other side of the base. A rotating hinged support is connected between the cover plate and the other side of the base. A screw rod nut is installed in the center of the cover plate in a vertically through mode. A rotating platform is installed at the upper end of a screw rod installed in the screw rod nut in a balanced mode. Adjustable studs which are used for tightly pressing a workpiece are evenly distributed on the rotating platform. The lifter is an electric lifter or a hydraulic lifter. The weld holder is particularly suitable for fillet welding in the flat position of the tower leg of the electric transmission line iron tower, and has the advantages of being simple in structure, convenient to operate, high in safety performance, high in welding speed, and good in welding quality.
Description
Technical field:
The utility model relates to metal processing, particularly a kind of iron tower of power transmission line tower leg fillet welding in the flat position weld holder that is applicable to.
Background technology:
In whole iron tower of power transmission line welding, because the profile of tower leg is very irregular, the requirement of butt welded seam is very high, general welding method has two kinds, a kind of is to adopt vertical position welding or horizontal welding, when this method is welded the main weld between base plate and riser, if sheet metal thickness surpasses 36 ㎜, then need to make a call to earlier the back welding seam one time, carry out two layers of welding again, three layers, four layers even five layers welding cappings just can meet the requirements of welding quality, when the weld seam of a tower leg is above in 10 roads, its welding job amount is very large, and not assurance of welding quality, then easily cause undercut, slag inclusion, overlap, misalignment, defectives such as reinforcement is not enough, even can cause some surperficial gross distortions, weld seam between riser and between gusset is like this equally, another kind method is called fillet welding in the flat position, and it is to be placed with the polylith backing plate below tower leg, forms the ship shape weld seam, this method is not because of there being a kind of fixedly weld holder, operate very inconveniently, have bigger danger, easily cause and run weldering, phenomenon appears doing over again.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, easy to operate, welding position not only can lifting but also iron tower of power transmission line tower leg fillet welding in the flat position weld holder that can 360 ° of adjustment.
The technical solution of the utility model is finished with following task, iron tower of power transmission line tower leg fillet welding in the flat position weld holder, it comprises a base, it is characterized in that: a lift is installed in the middle of the side on base, symmetry upwards is equipped with two leads on two wing bases of lift, upper surface is equipped with the cover plate of an inclination 15-25 degree on the flexible contact of lift and between the base opposite side, be connected with the rotation free bearing between cover plate and the base opposite side, at the center of cover plate up/down perforation a feed screw nut is installed, screw mandrel upper end balance in the nut is equipped with a rotation platform, is evenly equipped with the adjustable stud of workpiece pressing on rotation platform.Lift is electric up-down frame or hydraulic lifting frame.
The utility model is particularly suitable for the iron tower of power transmission line tower leg is carried out fillet welding in the flat position, have simple in structure, easy to operate, security performance is good, speed of welding is fast, quality is high.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is that an electronic or hydraulic elevator 4 is installed in the middle of base 5 one sides, symmetry upwards is equipped with two leads 2 on two wing bases of lift, upper surface is equipped with the cover plate 3 of an inclination 15-25 degree on the flexible contact of lift and between the base opposite side, be connected with between cover plate and the base opposite side and rotate free bearing 6, at the center of cover plate up/down perforation a feed screw nut 7 is installed, screw mandrel 8 upper end balances in the nut are equipped with a rotation platform 9, are evenly equipped with the adjustable stud 1 of workpiece pressing on rotation platform.During welding earlier with adjustable post with the fillet welding in the flat position Work-sheet pressing on rotation platform, can weld workpiece, can be during welding according to the needs rotation platform of weld seam to certain angle, the inclination angle can be adjusted with lift.Have simple in structure, use light flexibly, safe and reliable, keep welding quality.
