Description

Technical Field

[0001] The utility model relates to the technical field of pipeline rust removal, and particularly relates to a rust removal device for pipeline processing. Background Technique

[0002] In the pipeline processing industry, the surface of pipelines often rusts due to long-term exposure to air or other use environments. Rust not only affects the appearance of the pipeline, but more importantly, it will reduce the corrosion resistance and service life of the pipeline. In addition, the rust on the pipeline surface will also affect subsequent processing procedures, such as welding, coating, etc., thus affecting the quality and performance of the final product.

[0003] Traditional manual rust removal methods mainly include physical grinding using tools such as wire brushes and sandpapers, which are inefficient, labor-intensive, and difficult to ensure the consistency of rust removal quality; removing rust by chemical methods such as pickling can achieve better rust removal effects, but there are environmental pollution and safety hazards, and at the same time, it may also cause damage to the pipeline surface.

[0004] Therefore, the utility model proposes a rust removal device for pipeline processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rust removal device for pipeline processing to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rust removal device for pipeline processing includes a positioning tooling for clamping and fixing the pipeline, and a support component for installing and fixing the positioning tooling; the support component includes a bottom plate, a support frame fixed to the edge of the upper side of the bottom plate, a receiving arm integrally extending from the edge of the support frame, a rust removal strip movably fitted in the inner chute of the receiving arm, a connecting rod fixed to the end of the rust removal strip, and a cylinder for driving the telescopic movement of the connecting rod.

[0007] The positioning tooling includes a frame movably arranged inside the support frame, a support arm movably connected to the edge of the inner side of the frame, a mounting frame fixed to the end of the support arm, a positioning wheel movably arranged at the end of the mounting frame, and a micro-star motor and a bevel gear set for driving the rotation of the positioning wheel.

[0008] Preferably, the cylinder body is symmetrically fixed to the upper part of the outer side of the support frame, and a reinforcing member is arranged between the bottom side of the support frame and the bottom plate for reinforcement.

[0009] Preferably, a friction surface is arranged on the inner side of the rust removal strip, and the friction surface is matched with the circumferential side of the pipeline.

[0010] Preferably, the frame is connected to an external rotary drive. A rotary motor is fixed to the end face of the frame. The output shaft of the rotary motor is connected to a screw through a transmission gear set. A movable seat is threadedly fitted around the screw. A traction rod is connected to the side of the movable seat. The outer end of the traction rod is movably connected to the inner side of the support arm.

[0011] Preferably, a guide rod is fixed to the end face of the frame. A mounting seat is fixed to the end of the guide rod. The guide rod passes through the corner of the end of the movable seat. The end of the screw is movably connected to the mounting seat.

[0012] Preferably, stripes are evenly distributed on the circumferential side of the positioning wheel, and the positioning wheel is in contact and fit with the inner side wall of the pipeline.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the collaborative work of components such as the positioning tooling and the support assembly, the present utility model realizes the automatic clamping and fixing of the pipeline and rust removal, reduces the need for manual operation, and improves production efficiency; the movement of the rust removal strip is driven by a cylinder, and different diameters of pipelines can be adapted by adjusting the position of the positioning wheel, improving the application range of the device. The positioning wheel in the positioning tooling is in close contact with the inner wall of the pipeline, ensuring that the pipeline will not shift during the rust removal process and improving the safety of the work.

[0015] 2. When the micro star motor in the present utility model starts, the positioning wheel is driven to rotate through the bevel gear set, so that the pipeline is fixed between the positioning wheels. The positioning wheels in the two positioning toolings rotate alternately, which can realize the reciprocating linear drive of the pipeline.

The output shaft of the rotary motor 32 is connected to a screw rod 38 via a transmission gear set 311. A moving seat 312 is threadedly fitted and installed on the circumferential side of the screw rod 38. A traction rod 39 is connected to the side face of the moving seat 312. The outer end of the traction rod 39 is movably connected to the inner side of the support arm 33.

[0026] The rust removal device for pipeline processing is a device for removing rust on the surface of the pipeline 2. The detailed description of its technical solution is as follows:

[0027] In the support assembly 1, the bottom plate 11 provides the basic support for the entire device. The support frame 12 is fixed on the bottom plate 11 and is used for installing and supporting other components. The reinforcement is located between the bottom side of the support frame 12 and the bottom plate 11 to enhance the structural stability. The receiving arm 13 extends integrally on one side of the support frame 12 and has a chute inside. The rust removal strip 14 is installed in the chute of the receiving arm 13 and has a friction surface for contacting and removing the rust on the pipeline 2. One end of the connecting rod 16 is fixed to the rust removal strip 14, and the air cylinder 15 is used to drive the connecting rod 16, thereby adjusting the position of the rust removal strip 14 relative to the pipeline 2 to achieve rust removal treatment for pipelines 2 with different diameters.

[0028] In the positioning tooling 3, the frame 31 is movably arranged inside the support frame 12 and is connected to an external rotary drive. The rotary motor 32 is fixed to the end face of the frame 31 and is used to drive the rotation of the frame 31. The transmission gear set 311 connects the output shaft of the rotary motor 32 and the screw rod 38. The screw rod 38 is driven to rotate by the rotary motor 32 through the transmission gear set 311. The moving seat 312 is threadedly fitted and installed on the screw rod 38 and moves along its axial direction as the screw rod 38 rotates. The traction rod 39 connects the moving seat 312 and the support arm 33 and is used to transmit the movement of the moving seat 312. The support arm 33 swings relative to the frame 31 through the movement of the traction rod 39. The mounting frame 35 is fixed to the end of the support arm 33 and is used to install the positioning wheel 37. The micro-star motor 34 is used to drive the rotation of the positioning wheel 37. The bevel gear set 36 connects the micro-star motor 34 and the positioning wheel 37 to achieve power transmission. The positioning wheel 37 is installed at the end of the mounting frame 35, and stripes are evenly distributed on its circumferential side to increase the friction force with the inner wall of the pipeline 2 to ensure the stability of the pipeline 2.

[0029] After the rotary motor 32 starts, it drives the screw 38 to rotate through the transmission gear set 311. The rotation of the screw 38 causes the moving seat 312 to move along its axial direction. The movement of the moving seat 312 drives the swing arm 33 to swing through the traction rod 39, thereby adjusting the position of the positioning wheel 37. When the micro-star motor 34 starts, it drives the positioning wheel 37 to rotate through the bevel gear set 36, so that the pipe 2 is fixed between the positioning wheels 37. The positioning wheels 37 in the two positioning jigs 2 rotate alternately, which can realize the reciprocating linear drive of the pipe 2. Combined with the external rotary drive to control the overall rotation of the positioning jig 2, the swing and rotation movements of the pipe 2 fixed by the positioning jig 2 are compounded, improving its rust removal effect.
