Abstract
The invention discloses a welding frame for fillet welding in a flat position of a tower leg of a power transmission line iron tower. The welding frame for fillet welding in the flat position of the tower leg of the power transmission line iron tower comprises a base, wherein an elevator is arranged in the middle of one side on the base, two guide posts are symmetrically and upwards arranged on the base arranged at the two sides of the elevator, a cover plate inclined for 15 to 25 degrees is arranged on the upper surface arranged between the other side of the base and a position above a telescopic contact of the elevator, a rotating hinging seat is connected between the cover plate and the other side of the base, a lead screw nut is arranged in the center of the cover plate in a way of penetrating through the upper part and the lower part, a rotating platform is in balanced installation on the upper end of the lead screw arranged in the screw nut, and adjustable studs for tightly pressing workpeices are uniformly distributed on the rotating platform. The elevator is an electric ascending and descending frame or a hydraulic ascending and descending frame. The welding frame is particularly suitable for being used for the fillet welding in the flat position of the tower leg of the power transmission line iron tower and has the advantages that the structure is simple, the operation is convenient, the safety performance is good, the welding speed is high, and the quality is high.
Description
Technical field:
The present invention relates to intermetallic composite coating, particularly one is applicable to iron tower in power transmission line leg fillet welding in the flat position weld holder.
Background technology:
In whole iron tower of power transmission line welding, due to the profile very irregular of tower leg, the requirement of butt welded seam is very high, general welding method has two kinds, one adopts vertical position welding or horizontal welding, when this method is welded the main weld between base plate and riser, if sheet metal thickness is more than 36 ㎜, then need first to make a call to a back welding seam, 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 more than 10 roads, its welding job amount is very large, and welding quality does not ensure, then easily cause undercut, slag inclusion, overlap, misalignment, the defects such as reinforcement is inadequate, 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, it is below tower leg, be placed with polylith backing plate, form ship shape weld seam, this method is not because having a kind of fixing weld holder, operate very inconvenient, there is larger danger, easily cause and run weldering, there is doing over again phenomenon.
Summary of the invention:
The object of this invention is to provide that a kind of structure is simple, easy to operate, welding position not only can be elevated but also can the iron tower in power transmission line leg fillet welding in the flat position weld holders of 360 ° of adjustment.
Technical scheme of the present invention completes with following task, iron tower in power transmission line leg fillet welding in the flat position weld holder, it comprises a base, it is characterized in that: in the middle of submounts side, a lift is installed, on two wing bases of lift, symmetry is upwards provided with two leads, on the flexible contact of lift and between base opposite side, upper surface is provided with the cover plate of an inclination 15-25 degree, rotation free bearing is connected with between cover plate and base opposite side, at the center up/down perforation of cover plate, a feed screw nut is installed, screw mandrel upper end balance in nut is provided with a rotation platform, rotation platform is evenly equipped with the adjustable stud of workpiece pressing.Lift is electric elevating rack or hydraulic lifting frame.
The present invention is particularly suitable for carrying out fillet welding in the flat position to iron tower in power transmission line leg, has structure simple, easy to operate, security performance good, and speed of welding is fast, quality is high.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Embodiment is described in detail in conjunction with above accompanying drawing, the present invention is provided with an electronic or hydraulic elevator 4 in the middle of base 5 side, on two wing bases of lift, symmetry is upwards provided with two leads 2, on the flexible contact of lift and between base opposite side, upper surface is provided with the cover plate 3 of an inclination 15-25 degree, be connected with between cover plate and base opposite side and rotate free bearing 6, at the center up/down perforation of cover plate, a feed screw nut 7 is installed, screw mandrel 8 upper end balance in nut is provided with a rotation platform 9, rotation platform is evenly equipped with the adjustable stud 1 of workpiece pressing.During welding first with adjustable post by fillet welding in the flat position Work-sheet pressing on rotation platform, can weld workpiece, rotation platform can be needed to certain angle according to weld seam during welding, inclination angle can adjust with lift.Have structure simple, use flexibly light, safe and reliable, keep welding quality.
