[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 - 3 As shown, this embodiment is a welding clamping device for elbow joints in water conservancy construction, including:

[0031] A clamping assembly; the clamping assembly includes a placement plate 11;

[0032] The clamping assembly further includes a connecting plate 12, a first clamping ring 13, and a second clamping ring 14; the connecting plate 12 is hinged to the other end of the placement plate 11, the first clamping ring 13 is slidably connected to the top of the placement plate 11, and the second clamping ring 14 is located at the top of the connecting plate 12;

[0033] The placement plate 11 and the connecting plate 12 are respectively used for placing the two ends of the elbow joint, and the first clamping ring 13 and the second clamping ring 14 are used for limiting the elbow joint.

[0034] A limiting assembly, the limiting assembly includes a fixing plate 21, a spring 22, a limiting plate 23, a cross bar 24, a card slot 25, and a slider 26; the fixing plate 21 is fixed on both sides of the open end of the placement plate 11, the spring 22 is fixed on one side of the fixing plate 21, the limiting plate 23 is located at the top and both sides of the placement plate 11, the cross bar 24 is fixed above both sides of the placement plate 11, the card slot 25 is opened at the opposite ends of the cross bar 24, and the slider 26 is slidably connected to the inner side of the card slot 25, and the outer side of the slider 26 is fixedly connected to the inner side below the limiting plate 23;

[0035] The fixing plate 21 is used for connecting the spring 22, the spring 22 is used for connecting and moving the limiting plate 23, the limiting plate 23 is used for limiting the bent part of the elbow joint, the cross bar 24 is used for opening the card slot 25, the card slot 25 is used for connecting and moving the slider 26, and the slider 26 is used for assisting the movement of the limiting plate 23.

[0036] Fixed frames 27 are fixedly connected to the upper middle parts of both sides of the placement plate 11. The fixed frames 27 are located below the fixing plate 21, and magnetic areas 28 are fixedly connected to the outer sides of the fixed frames 27;

[0037] The magnetic areas 28 are set as a group. Vertical plates 29 are fixedly connected to both sides of the bottom end of the limiting plate 23, and the vertical plates 29 are adsorbed to the magnetic areas 28;

[0038] The fixing bracket 27 is used for the setting of the magnetic force area 28. The magnetic force area 28 is used for the connection and adsorption of the vertical plate 29. The vertical plate 29 is used for the connection between the limiting plate 23 and the magnetic force area 28. When the limiting plate 23 moves, the limiting plate 23 drives the vertical plate 29 to move together. Since the distance between the magnetic force areas 28 is relatively close and the vertical plate 29 is relatively wide, when the limiting plate 23 stops moving, the vertical plate 29 follows and stops moving. At this time, both sides of the vertical plate 29 will be adsorbed to the adjacent magnetic force areas 28, so that the magnetic force areas 28 limit the moved limiting plate 23 through the adsorption connection of the vertical plate 29, realizing the random stop of the limiting plate 23.

[0039] Working principle: When the component is not in use, the limiting plate 23 does not move and the spring 22 is not unfolded. When placing the elbow joint, pull the limiting plate 23 by hand. The thrust pushes the spring 22 to unfold, and the thrust pushes the slider 26 to move in the card slot 25 through the limiting plate 23, so that the limiting plate 23 drives the vertical plate 29 to move towards the connecting plate 12 through the spring 22 and the slider 26. Then connect the two ends of the elbow joint to the placing plate 11 and the connecting plate 12 respectively, so that the first clamping ring 13 and the second clamping ring 14 limit the two ends of the elbow. At this time, the limiting plate 23 stops moving. Since the distance between the magnetic force areas 28 is relatively close and the vertical plate 29 is relatively wide, when the limiting plate 23 stops moving, the vertical plate 29 follows and stops moving. At the same time, both sides of the vertical plate 29 will be adsorbed to the adjacent magnetic force areas 28, so that the magnetic force areas 28 limit the moved limiting plate 23 through the adsorption connection of the vertical plate 29, prompting the limiting plate 23 to be located at the outer end of the bending part of the elbow, so that the limiting plate 23 assists in limiting the clamped elbow;

[0040] The above steps avoid the shaking of the elbow joint during welding.

[0041] Please refer to Figures 1 - 2 、 Figure 4 As shown, on the basis of the above embodiment, this embodiment further includes:

[0042] Auxiliary limiting component;

[0043] The auxiliary limiting component includes a fixed box 31, a vertical groove 32, a moving block 33 and a connecting block 34. The fixed box 31 is fixed at the center of the bottom end of the opening of the placing plate 11. The vertical groove 32 is opened at both inner ends of the fixed box 31. The moving block 33 is slidably connected inside the vertical groove 32. The connecting block 34 is fixed between the opposite ends of the moving block 33;

[0044] The fixed box 31 is used for the placement and movement of the connecting block 34. The vertical groove 32 is used for the connection and movement of the moving block 33. The moving block 33 is used for the connection of the connecting block 34. The connecting block 34 is used for the opening of the groove 351 and the connection of the friction pad 35.

[0045] A friction pad 35 is fixedly connected to the top end of the connecting block 34. There are three groups of friction pads 35. A groove 351 is formed on one side of the connecting block 34, and a vertical hole 36 is formed at one inner end of the inner side of the vertical groove 32 on one side;

[0046] The vertical hole 36 communicates with the inside of the vertical groove 32. A push rod 37 is slidably connected to the inside of the vertical hole 36. The inner end of the push rod 37 is fixedly connected to the moving block 33;

[0047] The friction pad 35 is used to increase the friction between the connecting block 34 and the bottom end of the elbow joint. There are seven friction pads 35 in each group. The groove 351 is used for the clamping of the bottom end of the outer side of the elbow pipe below. The vertical hole 36 is used for the connection and movement of the push rod 37. The push rod 37 is used to push the moving block 33.

[0048] Working principle: When the component is not in use, the connecting block 34 is located inside the fixed box 31. When the component is in use, the first clamping ring 13 and the second clamping ring 14 limit the two ends of the elbow pipe. At this time, if the bottom end of the elbow pipe does not exceed the placement plate 11, push the push rod 37 by hand. The push rod 37 moves in the vertical hole 36. At the same time, the push rod 37 pushes the connecting block 34, so that the connecting block 34 moves upward in the vertical groove 32, and then pushes the elbow pipe, so that the outer side end below the elbow pipe is clamped with the groove 351 on the connecting block 34, prompting the connecting block 34 to limit the lower part of the elbow pipe through the groove 351. If the bottom end of the elbow pipe exceeds the placement plate 11, the connecting block 34 moves into the fixed box 31, so that the friction pad 35 at the top end of the connecting block 34 fits against the bottom end of the elbow pipe. Since the friction pad 35 increases the friction between the connecting block 34 and the bottom end of the elbow joint, the connecting block 34 limits the outer side end of the elbow pipe through the friction pad 35, so that the connecting block 34 and the limiting plate 23 are used in cooperation to prevent the elbow joint from shaking during welding;

[0049] The above steps can improve its own functionality.
