DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] In order to solve the problem that the current manual use of welding flanges to connect pipes is time-consuming, labor-intensive, and inefficient, and the welding posture cannot be adjusted according to needs, further reducing the welding efficiency. Figures 1 to 4 As shown, a welding bracket for facilitating pipe welding is proposed, comprising a support frame 1;

[0025] An angle steel 2 is welded on the top of the support frame 1, and a connecting column 3 is installed outwardly on the angle steel 2. The connecting column 3 is pressed by a clamp connected to the upper part of the angle steel 2;

[0026] The support frame 1 is composed of two A-shaped frames 101 welded from circular steel pipes with a reinforcing rod 102 welded in the middle. The materials are easy to obtain and the cost is reduced. At the same time, the support frame 1 provides good stability. The angle steel 2 is a commonly used forming component on construction sites or in factories. The angle steel 2 can position connecting columns 3 of different sizes and then be clamped by a clamp. At this time, the rotational freedom of the connecting column 3 in the angle steel 2 is not restricted, and the connecting column 3 can be rotated, thereby rotating the connecting seat 7 to rotate the pipe fitting and adjust the welding posture.

[0027] A connecting seat 7 is welded outwardly at the end of the connecting column 3, and a slide rail 701 is opened in the connecting seat 7. An adjusting rod is rotatably installed in the slide rail 701, and both ends of the adjusting rod extend through the two end walls of the connecting seat 7. The adjusting rod is configured as a screw rod 8 with threads at both ends rotating in opposite directions with the center as the axis of symmetry. Both ends of the screw rod 8 are respectively threadedly connected to the slide seats 901 of the two positioning plates 9. The two positioning plates 9 are slidably connected in the slide rail 701 through the slide seats 901, and the positioning plates 9 also use angle steels 2, and a clamp is also provided on the upper part of the positioning plates 9.

[0028] Connecting seats 7 are extended from both ends of the screw rod 8. After a group of pipe fittings are placed in two positioning plates 9 and clamped by clamps, the butt joints of the two pipe fittings are aligned. Then the screw rod 8 is rotated. With the threads rotating in opposite directions at both ends, the two positioning plates 9 slide toward each other on the connecting seats 7, and the welding parts of the two pipe fittings gradually approach each other until the welding parts of the two pipe fittings are butted and pressed, thereby quickly butting and pressing the welding parts of the pipe fittings to improve work efficiency.

[0029] The clamp includes a fixing bolt 4, a nut 5, and a connecting plate 6. The fixing bolt 4 is threadedly connected to the nut 5 arranged on the upper part of the positioning plate 9 and the angle steel 2 respectively. The nut 5 is welded to the positioning plate 9 and the connecting plate 6 connected upward to the side wall of the angle steel 2 respectively. The connecting plate 6 is welded and covered on the V-shaped side wall of the positioning plate 9 and the angle steel 2.

[0030] In order to further improve the welding efficiency, connecting columns 3 are symmetrically installed outward at both ends of the angle steel 2 of the welding bracket. The connecting columns 3 are pressed by a clamp connected to the upper part of the angle steel 2, so that welding operations can be performed at both ends of the welding bracket, increasing welding stations and improving welding operation efficiency.

[0031] Example 2

[0032] Different from Example 1, in order to improve the adaptability of the welding bracket to adapt to the height of different welding workers and facilitate the welding operation of the workers, refer to Figure 5 As shown, the support frame 1 includes two telescopic rods 103 symmetrically welded at both ends of the bottom of the angle steel 2, the bottom of the telescopic rod 103 is slidably sleeved in the telescopic sleeve 104, and a number of locking screw holes 1031 are equidistantly provided on the telescopic rod 103, and a locking screw 1041 corresponding to the direction of the locking screw hole 1031 is provided on the top of the telescopic sleeve 104;

[0033] By extending and retracting the telescopic rod 103 in the telescopic sleeve 104 and setting the locking screw hole 1031 and the locking screw 1041, the height of the support frame 1 can be quickly adjusted and locked to accommodate operation by workers of different heights.

[0034] In order to further improve the stability of the support frame 1, the bottoms of the two telescopic sleeves 104 are welded to the bottom plate 105, and the bottom plate 105 is placed on the ground to increase the contact area between the support frame 1 and the ground and improve stability.

[0035] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all details in detail, nor do they limit the utility model to only the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
