[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: including an installation device 1 and an expansion device 2.

[0020] In this technical solution, a clamping device for building pipe processing, the installation device 1 includes an installation plate 11, a moving column 12 and an electric push rod 13. The moving column 12 penetrates through the inside of the installation plate 11. The electric push rod 13 is connected to the outer side wall of the installation plate 11 through a cross plate. The cross plate is welded to the outer side wall of the installation plate 11. The electric push rod 13 is fixed to the bottom of the cross plate through bolts. The moving end of the electric push rod 13 is fixed with a moving block 131 through bolts. The moving block 131 extends into the inside of the moving column 12;

[0021] In this technical solution, the installation plate 11 is used to provide installation points for the installation of multiple parts. The electric push rod 13 and the moving block 131 cooperate with each other to apply a thrust to the moving column 12, so that the moving column 12 moves towards the installation ring 21.

[0022] The expansion device 2 includes a mounting ring 21, a moving mechanism 22 and a motor 24. The center of the mounting ring 21 is a hollow structure, and a plurality of moving grooves corresponding to the moving mechanism 22 are formed in the outer side wall of the mounting ring 21. The mounting ring 21 is connected to the mounting plate 11 through a cross bar 111. The plurality of cross bars 111 are annularly distributed along the mounting ring 21. Both ends of the cross bar 111 are fixed to the mounting plate 11 and the mounting ring 21 through bolts respectively. The plurality of moving mechanisms 22 are equally angularly distributed along the outer side wall of the mounting ring 21 and all point to the center of the mounting ring 21. The motor 24 is fixed to the end of the moving column 12 through a bolt. The motor 24 is connected to the mounting plate 11 through a spring 244. The plurality of springs 244 are annularly distributed along the motor 24. Both ends of the spring 244 are fixed to the mounting plate 11 and the motor 24 through bolts respectively. A connecting column 241 is key-connected to the driving end of the motor 24. A conical column 243 is fixed to the end of the connecting column 241 through a bolt. A plurality of blades 242 are welded to the outer side wall of the connecting column 241;

[0023] In this technical solution, the mounting ring 21 provides mounting points for the mounting of multiple parts. When the moving column 12 moves, it can drive the motor 24 and the connecting column 241 to move synchronously, so that the conical column 243 contacts the end of the moving plate 221, causing the entire moving mechanism 22 to move outward for the first time. At this time, the spring 244 is in a stretched state. The motor 24 can drive the connecting column 241 to rotate. When the connecting column 241 rotates, the arc surface on the outer side wall of the blade 242 contacts the upright column 226, causing the entire moving mechanism 22 to move outward for the second time until the pressing plate 222 contacts the inner side wall of the pipeline to complete clamping.

[0024] In some technical solutions, referring to Figure 1 、 Figure 2 and Figure 4 The moving mechanism 22 includes a moving plate 221, a pressing plate 222, an elastic cord 223 and an upright column 226. The moving plate 221 penetrates through the inside of the mounting ring 21 and moves in the moving groove. The pressing plate 222 is welded to the end of the moving plate 221 away from the mounting ring 21. The upright column 226 is welded to the end of the moving plate 221 close to the mounting ring 21. One end of the elastic cord 223 is connected to the pressing plate 222, and the other end is connected to the mounting ring 21 through a connecting plate 211. The connecting plate 211 is a U-shaped structure. The end of the elastic cord 223 is fixedly connected to the connecting plate 211 through a bolt. The connecting plate 211 is welded to the mounting ring 21.

[0025] In this technical solution, when the end of the movable plate 221 is driven by an external force, it will move along the movable groove away from the center of the mounting ring 21, and multiple movable plates 221 will move synchronously. At this time, the elastic rope 223 is in a stretched state until the extrusion plate 222 contacts the inner wall of the pipe. When the external force acting on the end of the movable plate 221 is released, the elastic rope 223 returns to its original state, driving the movable plate 221 to move toward the center of the mounting ring 21.

[0026] In some technical solutions, reference Figures 1-2 The motor 24 is covered with a mounting frame 23 on the outside. The mounting frame 23 is covered on the outside of the moving column 12 and the spring 244 and is fixed to the motor 24 by bolts. The mounting frame 23 is also fixed to the moving column 12 by bolts. The inner wall of the mounting frame 23 contacts the connecting column 241 through a retaining ring 231. The outer wall of the connecting column 241 is provided with an annular groove. The retaining ring 231 is located in the annular groove and can rotate. The retaining ring 231 is fixed to the inner wall of the mounting frame 23 by bolts.

[0027] In this technical solution, the use of the mounting frame 23 and the retaining ring 231 can limit the connecting column 241, so that the connecting column 241 can always maintain horizontal movement, so that the connecting column 241 is aligned with the center of the mounting ring 21 to complete the synchronous driving of multiple movable plates 221.

[0028] In some technical solutions, reference Figure 1 , Figure 2 and Figure 4 A convex strip 225 extends from the outer wall of the movable plate 221, and the convex strip 225 is in sliding contact with the inside of the mounting ring 21. A reinforcing plate 224 is welded at the angle between the movable plate 221 and the extrusion plate 222, and the extrusion plate 222 is an arc-shaped structure.

[0029] In this technical solution, the use of the convex strip 225 can limit the moving trajectory of the movable plate 221, and the reinforcing plate 224 can increase the connection strength between the extrusion plate 222 and the movable plate 221, so that the extrusion plate 222 can stably clamp the inner wall of the pipe.

[0030] In some technical solutions, reference Figure 2 and Figure 4 The outer part of the column 226 is sleeved with a sleeve, and the sleeve is in rolling contact with the blade 242.

[0031] In this technical solution, the use of the sleeve can reduce the friction resistance between the blade 242 and the column 226, so that when the sleeve rolls along the surface of the blade 242, the moving plate 221 can be pushed.

[0032] In some technical solutions, reference Figures 1-2, a trapezoidal through-hole is formed inside the moving column 12, the moving block 131 is of a trapezoidal structure, and the inclined surface of the moving block 131 is in sliding contact with the inclined surface of the trapezoidal through-hole.

[0033] In this technical solution, it is possible to conveniently apply a thrust to the moving column 12, so that the moving column 12 moves towards the mounting ring 21, and the tapered column 243 contacts the end of the moving plate 221.

[0034] Working principle: First, connect the electric push rod 13, the motor 24 with the external control device and the power supply. Use two sets of this device to be symmetrically distributed, and fix the mounting plate 11 on the ground or the workbench. In the initial state, the expansion device 2 is in a contracted state. Put the two ends of the pipeline on the outside of the expansion device 2 respectively. At this time, operate the control switch of the electric push rod 13, and the electric push rod 13 drives the moving block 131 to move downward. The moving block 131 squeezes the moving column 12 to move towards the mounting ring 21. At this time, the spring 244 is in a stretched state. When the moving column 12 moves, it drives the motor 24 and the connecting column 241 to move horizontally synchronously. When the tapered column 243 contacts the end of the moving plate 221, the moving plate 221 moves for the first time in the moving groove, so that the expansion device 2 is expanded for the first time. If the pipeline can be clamped during this expansion process, there is no need for a second expansion. If the pipeline cannot be clamped during this expansion, operate the control switch of the motor 24, and the motor 24 drives the connecting column 241 to rotate. When the connecting column 241 rotates, it presses the blades 242 against the upright column 226, so that the moving plate 221 moves in the moving groove again for the second expansion. At this time, the elastic cord 223 is in a stretched state until the pressing plate 222 contacts the inner side wall of the pipeline. At this time, two sets of this device can be used to complete the clamping of the pipeline for processing. After the processing is completed, operate the control switches of the electric push rod 13 and the motor 24 to reset. Then, during the process of the elastic cord 223 and the spring 244 returning to their original positions, the elastic cord 223 drives the moving plate 221 to move towards the center of the mounting ring 21, and the motor 24 moves towards the direction close to the mounting plate 11 under the pulling force of the spring 244, so that the tapered column 243 is separated from the moving plate 221, and the clamping of the pipeline is released, which is convenient for removing the pipeline.
