In the process, the hoisting steel beam is in the hoisting state of the crane, and although the method of early fixing is carried out by using bolts, the accuracy of the upper end and the lower end of the butt joint of the steel beam is lower due to the fact that the mass of the hoisting steel beam is larger, and the method is derived from the accuracy problem when welding operation is carried out: insufficient piling of welding filling metal, poor forming surface of welding seams, irregular surface, asymmetric welding legs and the like. And the welding of the building steel beams at the butt joint positions has higher requirements, and the problems seriously do not meet the building construction specifications of the steel structure. The applicant proposes that after positioning the hoisting steel beam and the welding steel beam, the welding position is fixed immediately, then the welding operation is continued, the position of the welding position is always higher, the duration time is longer, other unexpected situations can occur when manual welding is performed, and based on the above conception, the applicant proposes a building steel beam welding device which comprises a supporting seat with a hollow interior, a mechanical arm and a driving motor, wherein the mechanical arm is arranged on the upper end surface of the supporting seat and is used for performing the welding operation on the welding position; the up end of supporting seat is connected with the telescopic link to the free end of telescopic link is provided with the fixed subassembly that is used for fixed hoist and mount girder steel welded part, and the up end of supporting seat still is provided with the fixed column, and the blind hole that is used for fixed is seted up to the side of fixed column, and the side of fixed column still is provided with two fly leaves, and the tip of fly leaf articulates each other, and articulated department is provided with the round pin post, and the round pin post is fixed in the blind hole.

In the prior art, a building steel beam is generally a long steel material with an i-shaped section, and is widely used for various building structures. In the prior art, when welding butt joint of steel beams is needed between welding steel beams 6 which are fixedly installed on the upright posts, a hoisting steel beam 7 is usually hoisted to the air through a crane, and then butt joint positioning and subsequent welding operation between the welding steel beams 6 and the hoisting steel beam 7 are manually performed. In this process, the hoisting steel beam 7 is in the hoisting state of the crane, although the method of early fixing is performed by using bolts, due to the large mass of the hoisting steel beam 7, the precision of the upper and lower ends of the butt joint of the steel beams is low, and the precision problem is derived when the welding operation is performed: insufficient piling of welding filling metal, poor forming surface of welding seams, irregular surface, asymmetric welding legs and the like. And the welding of the building steel beams at the butt joint positions has higher requirements, and the problems seriously do not meet the building construction specifications of the steel structure. The applicant proposes that after positioning the hoisting steel beam 7 and the welding steel beam 6, the welding position is fixed immediately, and then the welding operation is continued, and the welding position is always higher and has longer duration, other accidents may occur when manual welding is performed, based on the above concept, the applicant proposes a building steel beam welding device, which comprises a supporting seat 2 with a hollow interior, a mechanical arm 1 and a driving motor 55, wherein the mechanical arm 1 is arranged on the upper end surface of the supporting seat 2 and is used for performing the welding operation on the welding position; the up end of supporting seat 2 is connected with the telescopic link to the free end of telescopic link is provided with the fixed subassembly 3 that is used for fixed hoist and mount girder steel 7 welded part, and the up end of supporting seat 2 still is provided with fixed column 5, and the blind hole that is used for fixing has been seted up to the side of fixed column 5, and the side of fixed column 5 still is provided with two fly leaves 51, and the tip of fly leaf 51 articulates each other, and articulated department is provided with round pin post 35, and round pin post 35 is fixed in the blind hole. In order to realize the fixed effect, a first spring 56 is further arranged on the side edge of the movable plate 51, a driving motor 55 is arranged on the surface of the free end of the movable plate 51, the output end of the driving motor 55 is connected with a roller 52, the outer peripheral surface of the roller 52 is in contact with a groove of the welding steel beam 6, an F-shaped clamp 53 is further arranged on the movable plate 51, and the clamping effect on the welding beam is realized by linkage of the roller 52.
It should be further noted that, because the mass of the welded steel beam 6 is often large, although the crane is used for hoisting the hoisting steel beam 7, the pressure effect on the telescopic rod is still large, and the telescopic rod in the invention is used for providing technical support for the displacement of the fixed assembly 3 in all directions, that is, the telescopic rod still has high mechanical strength when being telescopic. In view of the above, the applicant proposes to provide the first gas spring 42 inside the telescopic outer tube 41, and to provide a power source for stretching and compressing the telescopic inner rod 45 by utilizing the controllability of the gas spring, and it is noted that the first gas spring 42 is controlled by the central control module. Due to the fact that the bevel gear 47 and the toothed belt 46 are matched, the counter force can be buffered when the mass of the steel beam 7 is reacted and the telescopic rod is hoisted, and the instant acting force at the moment of contact can be greatly reduced. On the basis of the above-mentioned telescopic link being a buffer of the instantaneous force when the hoist steel beam 7 is in contact with the fixed assembly 3, in the conventional toothed belt 46, there is no toothed belt 46 shape capable of achieving the above-mentioned function, and on the basis of the above-mentioned circumstances, the applicant sets the tip of the toothed belt 46 to include a straight tooth face and an oblique tooth face, and the direction of the oblique tooth face coincides with the telescopic direction of the telescopic inner rod 45, and the direction of the straight tooth face is perpendicular to the telescopic direction of the telescopic inner rod 45. Through the above-mentioned structure, can realize that the telescopic link realizes freely stretching out and drawing back through the control of first gas spring 42 in the axis direction to can cushion a reaction force of hoist and mount girder steel 7, thereby reduce telescopic link pressure.
It should be noted that, when the telescopic inner rod 45 stretches outwards under the action of the first gas spring 42, the bevel face of the bevel gear 47 contacts with the bevel gear face of the toothed belt 46, the bottom of the bevel gear 47 is connected with the column 48, the bottom of the column 48 is provided with the spring, at this time, the spring is in a compressed state, the bevel gear face acts like a wedge, so that the bevel gear 47 moves downwards, and the stretching action of the telescopic inner rod 45 is realized; when the telescopic inner rod 45 has a tendency to contract under the action of the first gas spring 42, the straight tooth surface of the bevel gear 47 contacts with the straight tooth surface of the toothed belt 46, which is also the reason why the telescopic rod has a cushioning effect. However, because the connection between the rotary drum 44 and the telescopic inner rod 45 is a threaded connection, the telescopic inner rod 45 can drive the rotary drum 44 to rotate when being telescopic, so that the chamfer angle of the bevel gear 47 is arranged in the rotary drum 44
In the prior art, the connection of the hoisting steel beam 7 and the welding steel beam 6 at the connection part is high-strength bolt connection, but the bolt connection is inconvenient to position when the hoisting steel beam 7 is hoisted, the operations such as centering, bolt inserting, tightening and positioning are needed to be manually performed, the procedure is complicated, the precision is low, and besides the problems, the problems that the upper end and the lower end of the connection part are easily misaligned, and a large gap exists inside exist. In view of the above, the applicant proposes a new fixing assembly 3, in particular: the fixing assembly 3 includes: the fixed plate 33 with the pressure openings 311, the cam handles 38, the fixed blocks 32 and the pressing blocks 310 are arranged on two long sides, and it is to be noted that the fixed openings 31 are arranged on one short side of the fixed plate 33, the fixed blocks 32 are arranged in the fixed openings 31, the pressing blocks 310 are arranged in the pressure openings 311, two-way fixation of the hoisting steel beams 7 can be achieved through the fixed blocks 32 and the pressing blocks 310, the connection positions can be fixed according to the positions of the connection positions, and the connection positions are arranged between the pressing blocks 310. It should be further noted that, the pressing block 310 is further connected with the fixing plate 33 through the pressure spring 36, that is, a flexible fixation of the hoisting steel beam 7 can be achieved, which is different from a rigid fixation of the steel beam in the conventional technology, so that the problem of bad weld forming surface caused by rigid fixation welding on the welding seam during welding is avoided. It should be further noted that, the middle parts of the pressing block 310 and the fixing plate 33 are provided with a first through hole 37 for placing the tightening rod 312, one end of the tightening rod 312 is fixed on the pressing block 310, the other end is hinged on the cam handle 38, and tightening and loosening of the tightening rod 312 are achieved through rotation of the cam handle 38, and finally compression and loosening of the pressing block 310 are achieved.
