Disclosure of Invention

The purpose of this scheme is to provide a submerged arc welding auxiliary fixtures to solve flexible arm and have flexible inconvenient problem in flexible in-process.

In order to achieve the above-mentioned purpose, this scheme provides a submerged arc welding auxiliary fixtures, including the elevating platform, the elevating platform includes lift base and lift mesa, lift mesa cover is located on the lift base to can follow lift base and reciprocate, still include rack and flexible arm, flexible arm includes interior arm, outer arm and sliding element, sliding element includes pulley, connecting axle and connecting plate, the connecting plate is provided with two, and the symmetry sets up in outer arm both sides, a plurality of openings have been seted up on the outer arm, the pulley passes through the open position of connecting axle fixed connection at the outer arm, the end of interior arm is arranged in the outer arm inside to can stretch out and draw back under the effect of pulley, the end and the lift mesa fixed connection of outer arm, the front end fixed connection of rack and interior arm for assembly submerged arc welding machine.

The principle of the scheme is as follows: during welding, the lifting table top can move up and down through the lifting base, so that the telescopic arm on the lifting table top is driven to move up and down; the inner arm slides in the outer arm through the pulley, so that the telescopic arm can be lengthened and shortened; when the automatic submerged arc longitudinal seam welder is used, the existing automatic submerged arc longitudinal seam welder is installed on the placement frame, and the welder is moved to a required position for welding through movement of the telescopic arm.

The technical effect of this scheme lies in: the up-down displacement of the welding machine can be realized by arranging the lifting table top; the welder can realize front-back displacement by arranging the telescopic arm; the pulley is arranged, so that the inner arm stretches and contracts more smoothly in the outer arm, and further the inconvenience in stretching and contracting or the incapability of stretching and contracting caused by the fact that the inner arm is clamped can be prevented.

Further, corresponding limiting holes are formed in the inner arm and the outer arm, and the limiting holes are used for installing limiting pins. When the inner arm is extended to the required length, the limiting pin is inserted into the limiting hole, so that the inner arm and the outer arm are relatively fixed, and further, the inner arm and the outer arm are prevented from relative movement during welding of the welding machine, and the welding stability is ensured.

Further, the sliding units are arranged in a plurality and distributed on the upper side and the lower side of the outer arm. Both sides all set up in the pulley about, can make the inner arm more smooth and easy when the inside slip of outer arm.

Further, the sliding units on the upper side and the lower side are distributed in a staggered mode. The sliding units are distributed in a staggered manner, so that the contact surface between the inner arm and the pulley can be increased, and the inner arm is more stable during expansion and contraction.

Further, a rotating seat is fixedly arranged on the lifting table top, and the telescopic arm is fixedly connected with the rotating seat. The telescopic arm is arranged on the rotating seat, and can move left and right by rotating the rotating seat while moving up and down.

Further, a hanging cage is detachably connected to the placing frame. In the welding process, because the storage tank mouth is usually smaller, when the inner annular seam of the last seal head is welded, the welding machine is arranged on the hanging cage for welding, and the welding efficiency can be effectively improved.
