Description

Technical Field

[0001] The present application relates to the field of clamping tools, and in particular to a clamping tool for welding a double-gate air-lock wear-resistant valve pipeline flange. Background Art

[0002] When using the double-gate air-lock wear-resistant valve, it is usually necessary to connect the pipes at the corresponding position. When the pipes are connected to the double-gate air-lock wear-resistant valve, flanges are usually used for connection. Among them, the flanges on the pipes are usually welded manually. When welding the flanges, it is usually necessary to use a clamping tool to limit the pipes and flanges. The clamping tool mainly includes a workbench, a support and an adjustment seat. The support and the adjustment seat both slide along the length of the workbench. The pipes are placed on the support. There are two clamps on the adjustment seat. The clamps are used to clamp the flanges. Workers move the support and the adjustment seat according to the length of the pipe to adapt to pipes of different sizes.

[0003] The above-mentioned related technologies have the following defects. In actual use, the pipeline is prone to bending. Since the support slides along the length direction of the workbench, if the pipeline is bent, it is easy to cause the coaxiality between the pipeline and the flange to decrease, thereby causing the welding accuracy of the pipeline and the flange to decrease.

[0007] By adopting the above technical solution, the operator places the flange on the bracket and positions it through the positioning mechanism, and then places the pipe on the support wheel. When the pipe is bent, the operator can rotate the support, and the support can drive the support wheel to rotate, thereby driving the pipe to rotate and adjust the angle of the pipe, thereby improving the coaxiality between the pipe and the flange, and also improving the welding accuracy of the pipe and the flange.

[0008] Preferably, the limiting member is a limiting column, the limiting column is fixedly connected to the base, a limiting groove is provided on the support, and one end of the limiting column away from the base extends into the limiting groove.

[0009] By adopting the above technical solution, when the support rotates, the limiting column moves in the limiting groove.

[0020] Preferably, the support wheel and the support are rotatably connected.

[0021] By adopting the above technical solution, when the pipeline is placed on the support wheel, the operator can move the pipeline, and the support wheel can rotate at this time. Compared with the support wheel that cannot rotate, the rotating support wheel can reduce the friction between the support wheel and the pipeline, and reduce the possibility of wear and damage to the pipeline.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a clamping tool for welding a double-gate air-lock wear-resistant valve pipeline flange, such as Figure 1 As shown, it includes a track 1, a bracket 2 and a moving seat 3.

The support frame 41 is fixedly connected to the bracket 2, and the flange is placed in the support frame 41. The positioning assembly 42 includes a positioning column 421, a positioning block 422 and a positioning disk 423. The positioning block 422 is fixedly connected to the positioning column 421, and the positioning disk 423 is fixedly connected to the positioning column 421. A positioning hole 21 is provided on the bracket 2. When the flange is placed in the support frame 41, the positioning column 421 passes through the positioning hole 21 and is embedded in the screw hole of the flange.

The positioning column 421 can limit the flange in the support frame 41, the positioning block 422 can limit the positioning column 421 in the horizontal direction, and the positioning plate 423 can limit the positioning block 422, so that the positioning block 422 slides in the positioning hole 21, which is convenient for the positioning column 421 to limit the flange, improves the stability of the flange, and facilitates the welding of the pipeline and the flange.

[0034] like Figure 1 and 3 As shown, the movable seat 3 is provided with a base 5 that moves in the vertical direction, and a support 51 is rotatably connected to the base 5, and a support wheel 511 is rotatably connected to the support 51, and a pipeline is placed on the support wheel 511.
