Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a flange auxiliary disassembly device. Background Art

[0002] Flange is a commonly used connector with advantages such as wide application range and good connection performance. However, during the disassembly process, after the connecting screws on one side are removed, the flange connector will often tilt or shift under the influence of gravity or other factors, making it inconvenient and difficult to disassemble when removing the screws on the other side. Utility Model Content

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The utility model comprises an arc-shaped part, which is divided into two layers, an upper layer and an lower layer, wherein an arc-shaped groove is arranged in the middle of each layer, and an adjusting mechanism which can adjust the position according to different sizes of flanges is movably arranged in the arc-shaped groove, and an auxiliary clamping mechanism for assisting the flange in clamping is arranged at the outer edge of the arc-shaped part.

[0006] Preferably, the adjustment mechanism comprises a pair of extrusion shafts located in the arc-shaped groove, and an adjustment wheel is rotatably provided on the extrusion shaft for adapting to flanges of different radii.

[0007] Furthermore, guide wheels are symmetrically fixedly arranged on the upper and lower sides of the adjusting wheel, a guide groove is formed in the middle of the guide wheel, the outer side of the guide groove cooperates with the guide rail flange, and the guide rail flange is fixedly arranged on the inner wall of the arc groove.

[0008] Furthermore, the adjustment mechanism also includes an extrusion head fixedly connected to the extrusion shaft, and the extrusion head is arranged on the opposite side of the arc-shaped member.

[0009] Preferably, the auxiliary clamping mechanism includes the threaded rod, the lower end of the threaded rod is rotatably connected to the lower layer of the arc-shaped member, and the other end is threadedly connected to the upper layer of the arc-shaped member, and the movable end of the threaded rod is fixedly provided with a connecting head. By twisting the connecting head, the upper and lower layers of the arc-shaped member are gradually approached, thereby achieving clamping of the flange.

[0010] Furthermore, guide rods are provided on the arc-shaped parts on both sides of the threaded rod, and the lower ends of the guide rods fix the lower layer of the arc-shaped parts, and the upper ends of the guide rods are slidably connected to the upper layer of the arc-shaped parts.

[0011] The beneficial effect of the utility model is that the device can adjust the clamping position according to the size of different flanges through the adjustment mechanism. Since the shape of the arc-shaped part is not a perfect circle, flanges of different radii can partially fall between the arc-shaped parts, thereby improving the adaptability of the device. Subsequently, the flange part falling between the arc-shaped parts can be clamped by the auxiliary clamping mechanism, thereby assisting in the flange disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figure 1 As shown, the embodiment of the present application includes an arc-shaped member 10, which is divided into two layers, the upper and lower layers. The arc-shaped member 10 is arc-shaped as a whole, and the curvature is similar to an elliptical arc rather than a perfect circle. An arc-shaped groove 20 is provided in the middle of each layer, and an adjustment mechanism that can adjust the position according to different sizes of flanges is provided in the middle of the arc groove 20. An auxiliary clamping mechanism for assisting the flange in clamping is provided at the outer edge of the arc-shaped member 10.

[0020] like Figure 1 , Figure 2 and Figure 4As shown, in a certain example, the adjustment mechanism includes a pair of extrusion shafts 12 located in the arc groove 20, an adjusting wheel 19 is rotatably arranged on the extrusion shaft 12, and guide wheels 13 are symmetrically fixedly arranged on the upper and lower sides of the adjusting wheel 19, and a guide groove 14 is formed in the middle of the guide wheel 13, and the outer side of the guide groove 14 cooperates with the guide rail flange 15, and the guide rail flange 15 is fixedly arranged on the inner wall of the arc groove 20; when the position of the adjusting wheel 19 needs to be adjusted, the operator manually turns the adjusting wheel 19, and the adjusting wheel 19 will slide in the arc groove 20 at the same height position within the limits of the guide groove 14 and the guide rail flange 15, so as to adapt to flanges of different radii.

[0021] Further, if Figure 2 and Figure 3 As shown, the adjustment mechanism further includes an extrusion head 18 fixedly connected to the extrusion shaft 12 , and the extrusion head 18 is arranged on the opposite side of the arc-shaped member 10 .

[0022] like Figure 2 , Figure 5 and Figure 6 As shown, in a certain example, the auxiliary clamping mechanism includes the threaded rod 16, the lower end of the threaded rod 16 is rotatably connected to the arc-shaped member 10 on one side, and the other end is threadedly connected to the arc-shaped member 10 on the other side, and the movable end of the threaded rod 16 is fixedly provided with a hexagonal connector 17, and the arc-shaped members 10 on both sides of the threaded rod 16 are provided with guide rods 11, the lower end of the guide rod 11 is fixed to the arc-shaped member 10 on the lower side, and the upper end is slidably connected to the arc-shaped member 10; when the flange needs to be clamped, the threaded rod 16 is rotated by a tool in conjunction with the hexagonal connector 17, and the rotation of the threaded rod 16 will cause the arc-shaped member 10 on one side to move under the guiding action of the guide rod 11, so that the flange is clamped by the extrusion head 18. The extrusion head 18 is made of a material with a large friction coefficient and strength.

[0023] The use process of this device is as follows: when disassembling the flange, the flange is made to fall between the arc-shaped parts by using the adjustment mechanism, and is clamped by the auxiliary clamping mechanism; after being clamped, the flange will not be tilted or offset due to gravity or other factors that may cause the flange connection to be removed during the disassembly process, thereby playing a role in assisting disassembly.
