Description

Technical Field

[0001] The invention relates to the technical field of pipeline welding, and in particular to a welding pipe workbench and an operating method. Background Art

[0002] During the annual maintenance of the turbine generator units in the hydroelectric power plant, a large number of circular steel pipes need to be welded and matched due to on-site work and technical transformation needs; welded pipes are often welded with pipes of the same diameter, but there are also some special cases, such as welding pipes of similar diameters with different diameters. At this time, when welding on site, welders often compare the concentricity by hand based on experience, and the welded pipes have different concentricities. At the same time, due to the inconsistent concentricity of the two pipes, it is easy to cause water flow fluctuations and the Karman vortex effect. The flow meter on the pipeline after welding is distorted, resulting in the failure of technical transformation to monitor the flow.

[0003] Therefore, in order to ensure the concentricity of pipes of the same or similar diameters during welding, to reduce the flow fluctuation of the pipes after welding, to reduce piping welding errors, to increase the success rate of on-site welding and piping, and to improve the efficiency of on-site maintenance work, a simple welding and piping workbench is required to facilitate the work of operators.

[0004] Based on the above technical problems, we propose a welding pipe workbench and an operating method. Summary of the invention

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1

[0027] Reference Figure 1 to Figure 3, which is the first embodiment of the present invention, provides a welding pipe workbench, including a clamping assembly 100, the clamping assembly 100 includes a limiting hoop 101 for fixing the pipe; and the clamping assembly 100 is provided with two groups distributed in a straight line with each other, and the two groups of clamping assemblies 100 respectively fix two pipes to be welded through the limiting hoop 101.

[0028] There are two groups of clamping assemblies 100, and these two groups of clamping assemblies 100 can be arranged in any direction, but they need to be placed to form a line of assemblies to ensure the subsequent butt connection of steel pipes.

[0029] Preferably, the clamping assembly 100 further includes a first bracket 102 and a second bracket 103 which are staggered and connected to each other; a first area M is formed above the first bracket 102 and the second bracket 103 , and a second area N is formed below the first bracket 102 and the second bracket 103 .

[0030] It should be further explained that the first bracket 102 and the second bracket 103 are preferably staggered to form an "X" shape. A total of four "X"-shaped brackets are arranged on the steel plate table 201, and two "X"-shaped brackets form a pair. A round tube to be welded is placed horizontally on each pair of brackets, and a total of two round tubes to be welded can be placed.

[0031] Each set of clamping assemblies 100 includes two “X”-shaped brackets. Two sets of clamping assemblies 100 are provided to clamp two steel pipes respectively.

[0032] Preferably, an elastic member 104 is disposed in the second region N, and one end of the elastic member 104 is connected to the first bracket 102 , and the other end of the elastic member 104 is connected to the second bracket 103 .

[0033] The elastic member 104 is preferably a spring to provide a fastening force to the round tube.

[0034] Specifically, the spring under the "X"-shaped bracket is relatively long. Each time the pipe is placed on the bracket, the spring needs to be compressed to provide a tightening force. The "X"-shaped bracket has a limiter on top to fix the pipe, and a spring on the bottom. Each time the top is opened, the spring below will be compressed and tightened with elastic force.

[0035] Preferably, two limiting hoops 101 are provided in the first region M, and one of the limiting hoops 101 is fixedly connected to the first bracket 102 via a connecting rod 101a, and the other limiting hoops 101 is fixedly connected to the second bracket 103 via a connecting rod 101a.

[0036] The limiting hoop 101 can prevent the round tube from rolling and adapt to round tubes of different diameters. Each "X"-shaped bracket is equipped with two limiting hoop 101 to clamp the round tube from both sides.

[0037] The two circular pipes to be welded need to be welded with their centers in concentric circles. Generally, pipes with the same diameter are welded. However, during on-site operations, pipes with different diameters or similar diameters may also be welded. Therefore, by setting the clamping assembly 100, it is helpful to align the concentricity of pipes with the same or similar diameters.

[0038] In summary, when pipes of different diameters are placed between the "X"-shaped brackets, the elastic member 104 is compressed. After being released, under the action of the elastic member 104, the first bracket 102 and the second bracket 103 rotate and gather toward the center, so that the pipes are driven to maintain a centered position, and the limiting hoop 101 prevents the movement of the pipes during subsequent welding, so that pipes with the same or similar diameters can remain concentric. Compared with unstable handholding, which causes inconsistent concentricity of the two steels when welding, and reduces water flow fluctuations, this setting can greatly reduce errors in piping welding.

[0039] Example 2

[0040] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, is based on the previous embodiment, and the difference is that the clamping assembly 100 also includes two height telescopic rods 105 arranged at intervals, and the top of the height telescopic rod 105 is provided with a connecting frame 106, and the connecting frame 106, the first bracket 102 and the second bracket 103 are movably connected by connecting bolts 106a.

[0041] In detail, the telescopic rod 105 can be extended and retracted to change the vertical height of each group of "X"-shaped brackets; the two groups of "X"-shaped brackets can be set at different vertical heights to adapt to the welding work of two steel pipes with different diameters on site; by adjusting the height of the two pairs of brackets, the two steel pipes with different diameters can have the same centrality, thereby improving the quality of welded piping.

[0042] The connecting bolt 106a can adjust the tightness of the "X"-shaped bracket. After being loosened by rotating counterclockwise, the opening of the "X"-shaped bracket can be adjusted to adapt to a larger size of round pipe to be welded.

[0043] Preferably, a length telescopic rod 107 is connected between the two height telescopic rods 105 .

[0044] Furthermore, the length telescopic rod 107 is arranged between each pair of "X" brackets, and the length can be extended and retracted so that the length between each pair of "X"-shaped brackets can be changed to adapt to the support and fastening of round pipes to be welded of different lengths; when the length of the steel pipe is relatively long, the length telescopic rod 107 needs to be used to appropriately extend the distance between the "X"-shaped brackets so that it can be clamped securely.

[0045] Preferably, a magnetic base 108 is provided below the height telescopic rod 105 , and a magnetic manual switch 108 a is provided on the magnetic base 108 .

[0046] The magnetic base 108 has strong magnetism; each pair of "X"-shaped brackets has two magnetic bases 108, and the bottom surface of the magnetic base 108 has high flatness. After turning on the magnetic manual switch 108a, it can be firmly adsorbed on the steel table 201 flatly; the magnetic manual switch 108a controls whether the magnetic base 108 has strong magnetism. After the magnetic manual switch 108a is turned on, the magnetic base 108 has strong magnetism.

[0047] Preferably, a moving assembly 200 is further provided below the clamping assembly 100 , and the moving assembly 200 includes a steel plate table 201 that movably cooperates with the magnetic base 108 , and a universal wheel 202 is provided below the steel plate table 201 .

[0048] Among them, the steel plate table 201 is mainly a steel flat tabletop, which is the basic surface of the workbench and has high flatness.

[0049] The universal wheels 202 can roll, which facilitates the transportation and movement of the workbench during on-site maintenance work.

[0050] In summary, by setting the height telescopic rod 105 and the length telescopic rod 107, the "X"-shaped bracket can be adjusted to the corresponding position according to the height and length of the pipe, so as to facilitate pipe welding in different usage scenarios.

[0051] Example 3

[0052] Reference Figure 1 to Figure 3 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that this embodiment provides an operation method.

[0053] Specifically, the steel plate table 201 is moved to the welding operation area by using the universal wheel 202; the height of the first bracket 102 and the second bracket 103 are adjusted by the height telescopic rod 105; the magnetic manual switch 108a is turned on to make the magnetic base 108 generate strong magnetism so that the magnetic base 108 can be stably adsorbed on the steel plate table 201; the two pipes to be welded are placed on two sets of clamping assemblies 100 respectively.

[0054] Preferably, the pipeline is fixed by a limiting hoop 101, and welding work is started after the two pipelines are aligned.

[0055] After the steel plate table 201 is moved to the welding operation area using the universal wheels 202, it is necessary to ensure that the workbench is level and stable to avoid shaking during the welding process.

[0056] After turning on the magnetic manual switch 108a, check whether the magnetic base 108 is completely adsorbed on the steel plate table 201 to ensure its stability and safety.

[0057] When the height of the first bracket 102 and the second bracket 103 are adjusted by the height telescopic rod 105 , the heights of the two brackets can be made consistent or fine-tuned according to welding requirements to ensure the concentricity of the pipeline.

[0058] In summary, the provided welding and piping workbench is easy to make and convenient to weld, which reduces the tediousness of the workers' hand-held work, ensures the concentricity of the two pipes, and is also suitable for the welding of pipes of different sizes.
