[0003] 1. The main heat dissipation method is convection. The appearance and inner cavity are clean, with good heat dissipation performance, high pressure-bearing capacity, simple structure, and extremely simple installation and maintenance. It is applicable to various large thermal power plants and large industrial workshop buildings.
[0004] 2. It has a long service life, fast heat dissipation, a large radiator area, a wide application range, is easy to clean, and requires no maintenance, which are its remarkable features.
[0005] 3. The heating system has the characteristics of energy conservation. It can be stopped after work, and the remaining heat can ensure that mechanical equipment is not frozen. It can be turned on during work, with the characteristics of energy conservation and environmental protection.
[0006] This radiator is made by welding and connecting seamless pipes, blind plates, and connecting pipes. Among them, the seamless pipes are relatively long. The conventional method for welding between the seamless pipes and the blind plates is to place them on the operating table and perform group welding between the seamless pipes and the blind plates according to the designed dimensions on the drawing. After a batch of group welding is completed, another welder performs full welding. When performing full welding, the weld forms a vertical gap, which belongs to vertical welding. Vertical welding requires a very high technical level of the welder and has a slow welding speed.
[0007] In order to overcome the difficulties in radiator welding, a pipeline welding bracket for improving welding efficiency is proposed. Utility Model Content
[0008] The purpose of the utility model is to provide a pipeline welding bracket for improving welding efficiency, which is used to solve the technical problem that the pipeline welding process is relatively difficult, and can greatly shorten the construction period and reduce costs.

[0010] A pipeline welding bracket for improving welding efficiency includes a rod bracket, and the rod bracket is provided with one or more fixing clamps for fixing pipelines; the rod bracket is symmetrically provided with two isosceles triangular brackets, a cross bar one is connected between the bottoms of the two isosceles triangular brackets, one vertical rod is connected upward at each end of the cross bar one, the two vertical rods are respectively arranged on the perpendicular bisectors of the isosceles triangular brackets, a cross bar two is connected between the tops of the two vertical rods, and the fixing clamps are fixed on the cross bar two.
[0011] During application, move the rod support to the pipe processing platform, stand up the pipe and clamp it on the fixed fixture. Place one end of the pipe on the first cross bar. The welder does not need to perform vertical welding and can perform full welding on the blind plate and seamless pipe by using horizontal welding method.
[0012] Further preferably, the fixed fixture includes a movable fixture. One end of the fixed fixture is provided with a slot, and the movable fixture is assembled in the slot. The use of the movable fixture can make the support adapt to pipes of various diameters.

The rotating bases are located directly below the fixed fixture and correspond to the fixed fixture one by one. One end of the pipe is placed on the rotating bases on the first cross bar. In this way, the welder can rotate the pipe during construction without the welder rotating around the blind plate.
[0015] Further preferably, the rotating base can be rotated in the following way. The rotating base includes an upper support plate.

[0027] The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0028] A pipe welding bracket for improving welding efficiency, including a rod bracket 1, and the rod bracket 1 is provided with one or more fixing clamps 2 for fixing pipes; two isosceles triangular brackets are symmetrically arranged on the rod bracket 1, and a first cross bar 11 is connected between the bottoms of the two isosceles triangular brackets. One vertical rod 12 is connected upward at each end of the first cross bar 11. The two vertical rods 12 are respectively arranged on the perpendicular bisectors of the isosceles triangular brackets. A second cross bar 13 is connected between the tops of the two vertical rods 12. The fixing clamps 2 are fixed on the second cross bar 13, and the fixing clamps 2 can be evenly arranged on the second cross bar 13, which is beneficial for multiple welders to work simultaneously.
[0029] The fixing clamp 2 includes a movable clamp 21. One end of the fixing clamp 2 is provided with a clamping groove 22, and the movable clamp 21 is assembled in the clamping groove 22. The length of the vertical rod 12 is greater than half of the height of the pipe. In this embodiment, the fixing clamp 2 is two angle steels with a clamping groove 22 at one end. The clamping groove 22 is arranged on one side of the angle steel. The end of the angle steel without the clamping groove 22 is fixed on the second cross bar 13. The sides of the two angle steels with the clamping grooves 22 are vertical and the other sides are horizontal and fixed on the second cross bar 13 in the same horizontal plane. If the distance between the two angle steels is too large, the movable clamp 21 can be used to clamp in the clamping groove 22 to prevent the pipe from tipping over. In this embodiment, the movable clamp is a third angle steel, and the length of the third angle steel is slightly longer than the distance between the two angle steels. One side of the third angle steel is clamped into the clamping groove 22, so that the moving space of the pipe in the fixing clamp 2 is enclosed. If there is no movable clamp 21, a fixing block can be inserted between the vertical sides of the two angle steels to prevent the pipe from tipping over.
[0030] One or more rotating bases 3 are rotatably connected to the rod bracket 1. The rotating bases 3 are horizontally arranged on the first cross bar 11. The rotating bases 3 are located directly below the fixing clamps 2 and correspond to the positions of the fixing clamps 2 one by one.
[0031] The rotating base 3 includes an upper support plate 31. The upper support plate 31 is fixedly connected with a middle support pipe 32. The middle support pipe 32 is connected with a lower support plate 33. The middle support pipe 32 is sleeved inside a steel sleeve 34. The bottom of the steel sleeve 34 is fixed on the first cross bar 11. A rotating part 35 is arranged at the inner bottom of the steel sleeve 34. The lower support plate 33 presses on the rotating part 35 of the steel sleeve 34. In this embodiment, the rotating part 35 is a pressure bearing. The pressure bearing is placed inside the steel sleeve 34, and the lower support plate 33 presses on the pressure bearing. By rotating the pipe on the upper support plate 31, the upper support plate 31 can be driven to rotate. The pressure bearing is used to enable the lower support plate 33 to rotate.
[0032] The working principle is as follows: The rod bracket 1 stands on the pipeline construction platform. The lower support plate 33 is placed into the steel casing 34. Since there is a pressure bearing in the steel casing 34, the upper support plate 31 can rotate. Then, the seamless steel pipe with a blind plate spot-welded at one end is held vertically in the fixed fixture 2 after being erected. One end of the seamless steel pipe is placed on the upper support plate 31. When the welder operates, the seamless steel pipe and the blind plate can be fully welded by manually rotating the pipeline.
[0033] The advantages of using the present utility model are as follows: When the welder operates, he can rotate it easily while welding until a circumferential weld is formed between the blind plate and the seamless steel pipe.
[0034] The above are only specific embodiments of the present utility model, enabling those skilled in the art to understand or implement the present utility model. Although the above embodiments have been described in detail with reference to the foregoing, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the above embodiments, and they should all be covered by the protection scope of the claims.
