Description

Technical Field

[0001] This utility model relates to the field of steel pipe anti-corrosion treatment technology, specifically to an energy-saving composite steel pipe anti-corrosion treatment device. Background Technology

[0002] In the fields of petrochemicals and municipal water supply, composite steel pipes are widely used due to their high strength and corrosion resistance. The quality of their anti-corrosion treatment directly determines the service life and operational safety of the pipeline. With the surge in demand for long-distance, large-diameter pipeline projects, the traditional steel pipe inner wall anti-corrosion technology, which relies on manual operation, has gradually become a bottleneck restricting production efficiency and quality stability.

[0003] Existing anti-corrosion treatment equipment suffers from poor coating uniformity. When manually pulling and rotating the spraying mechanism, unstable control of force and speed easily leads to uneven coating thickness, with some areas being too thin or too thick, creating weak points in the anti-corrosion process. Secondly, production efficiency is low, requiring a dedicated person to operate the entire process for each steel pipe, which is time-consuming and cannot meet the rapid delivery requirements of large-scale projects. Furthermore, the labor intensity is high, as manually dragging the spraying equipment requires a lot of physical strength, and long-term operation can easily lead to fatigue, further increasing the risk of operational errors. At the same time, it is difficult to guarantee consistent quality. Differences in the techniques of different operators lead to fluctuations in the anti-corrosion effect between batches, increasing the cost of quality inspection and rework. Therefore, there is an urgent need for an energy-saving composite steel pipe anti-corrosion treatment equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving composite steel pipe anti-corrosion treatment device to solve the problem mentioned in the background art that the rhythm of manual pulling is difficult to control, resulting in uneven spraying and thus affecting the anti-corrosion effect of the steel pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving composite steel pipe anti-corrosion treatment equipment, including a fixed frame, a rotating spraying mechanism provided on the top surface of the fixed frame, and a uniform speed retraction component provided on the top surface of the fixed frame;

[0006] The uniform speed recovery assembly includes a rotating column rotatably connected to the inner wall of a fixed frame. A winding frame is fixedly connected to the surface of the rotating column, and a winding rope is sleeved on the surface of the winding frame. One end of the winding rope is fixedly connected to the inner wall of the winding frame. An output shaft is rotatably connected to the inner wall of the fixed frame. A motor is fixedly connected to the side wall of the fixed frame. The surface of the output shaft is fixedly connected to the output end of the motor. Synchronous pulleys are fixedly connected to both the surface of the rotating column and the surface of the output shaft. The surfaces of the two synchronous pulleys are sleeved with the same synchronous belt.

[0007] Preferably, the surface of the fixed frame is detachably connected to the mounting frame by bolts, the top surface of the mounting frame is provided with a support frame, the inner wall of the support frame is fixedly connected with a constraint tube, the side wall of the rotary spraying mechanism is fixedly connected with a constraint column, the constraint column is movably sleeved with the inner wall of the constraint tube, the right end of the constraint column is provided with a connecting groove, and the other end of the winding rope is engaged with the inner wall of the connecting groove.

[0008] Preferably, the top surface of the mounting bracket is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a threaded post, the upper end of which abuts against the bottom surface of the support bracket.

[0009] Preferably, the bottom surface of the support frame is provided with a plurality of sliding holes, and the inner wall of the sliding holes is slidably connected with sliding columns, and the lower ends of the plurality of sliding columns are fixedly connected to the top surface of the mounting frame.

[0010] Preferably, the surface of the threaded column is threaded with a fixing nut, and the upper end of the fixing nut abuts against the inner wall of the mounting bracket.

[0011] Preferably, a compression spring is fitted onto the surface of the sliding column, and the lower ends of the plurality of compression springs abut against the surface of the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The uniform speed recovery assembly ensures that the motor output rotates at a constant speed. This rotation, achieved through the coordinated action of the synchronous pulley and belt, drives the rotating column and winding frame to rotate at a constant speed. The winding frame's uniform rotation causes the winding rope to be wound at a constant speed, which in turn drives the rotary spraying mechanism to move uniformly along the inner wall of the steel pipe. This uniform movement of the rotary spraying mechanism facilitates even spraying of the inner wall of the steel pipe, thereby improving the corrosion resistance of the composite steel pipe's inner wall. Furthermore, the coordinated use of the mounting frame, support frame, and constraint columns facilitates the receiving and support of the rotary spraying mechanism at the end of its spraying process, improving the integrity of the coating on the inner wall of the steel pipe and further enhancing its corrosion resistance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-2 This utility model provides an energy-saving composite steel pipe anti-corrosion treatment device, including a fixed frame 1. A rotary spraying mechanism 2 is installed on the top surface of the fixed frame 1, and a uniform speed retraction assembly 3 is also installed on the top surface of the fixed frame 1. The uniform speed retraction assembly 3 includes a rotating column 301, which is rotatably connected to the inner wall of the fixed frame 1. A winding frame 302 is fixedly connected to the surface of the rotating column 301, and a winding rope 303 is sleeved on the surface of the winding frame 302. One end of the winding rope 303 is fixedly connected to the inner wall of the winding frame 302. An output shaft 304 is rotatably connected to the inner wall of the fixed frame 1, and a motor 305 is fixedly connected to the side wall of the fixed frame 1. The surface of the output shaft 304 is fixedly connected to the output end of the motor 305. Synchronous pulleys are fixedly connected to both the surface of the rotating column 301 and the surface of the output shaft 304. 306. The surfaces of the two synchronous pulleys 306 are fitted with the same synchronous belt 307. Through the uniform speed retraction component 3, the output end of the motor 305 rotates at a uniform speed. The synchronous pulleys 306 and the synchronous belt 307 work together to drive the rotating column 301 and the winding frame 302 to rotate at a uniform speed. The uniform speed rotation of the winding frame 302 causes the winding rope 303 to be wound at a uniform speed. The uniform speed winding of the winding rope 303 drives the rotary spraying mechanism 2 to move at a uniform speed on the inner wall of the steel pipe. The uniform speed movement of the rotary spraying mechanism 2 facilitates the uniform spraying of the inner wall of the steel pipe. By uniformly spraying the inner wall of the steel pipe, the anti-corrosion effect of the inner wall of the composite steel pipe is improved. The rotary spraying mechanism 2 is a common spraying component in the prior art. It is presented as prior art in this application and will not be described in detail here.

[0019] Furthermore, the surface of the fixed frame 1 is detachably connected to the mounting frame 308 by bolts. The top surface of the mounting frame 308 is provided with a support frame 309. The inner wall of the support frame 309 is fixedly connected to a constraint tube 310. The side wall of the rotary spraying mechanism 2 is fixedly connected to a constraint column 311. The constraint column 311 is movably sleeved with the inner wall of the constraint tube 310. The right end of the constraint column 311 is provided with a connecting groove 312. The other end of the winding rope 303 is engaged with the inner wall of the connecting groove 312. Through the cooperation of the mounting frame 308, the support frame 309 and the constraint column 311, it is convenient for the constraint column 311 to enter the inner wall of the constraint tube 310 when the rotary spraying mechanism 2 sprays to the end. This facilitates the receiving and support of the rotary spraying mechanism 2, thereby improving the integrity of the spraying on the inner wall of the steel pipe and providing a better anti-corrosion effect for the inner wall of the steel pipe.

[0020] Furthermore, the top surface of the mounting bracket 308 is provided with a threaded hole 316, and the inner wall of the threaded hole 316 is threaded with a threaded post 317. The upper end of the threaded post 317 abuts against the bottom surface of the support bracket 309. The threaded hole 316 and the threaded post 317 cooperate with each other to facilitate the adjustment of the position of the support bracket 309, thereby facilitating the smooth entry of the constraint post 311 into the inner wall of the constraint tube 310.

[0021] Furthermore, the bottom surface of the support frame 309 is provided with multiple sliding holes 313, and the inner wall of the sliding holes 313 is slidably connected with sliding columns 314. The lower ends of the multiple sliding columns 314 are fixedly connected to the top surface of the mounting frame 308. The multiple sliding columns 314 facilitate the limiting of the support frame 309, thereby facilitating the parallel up and down movement of the support frame 309.

[0022] Furthermore, the threaded post 317 is threaded with a fixing nut 318. The upper end of the fixing nut 318 abuts against the inner wall of the mounting bracket 308. The fixing nut 318 makes it easy to fix the threaded post 317 after adjustment, making the support of the threaded post 317 on the support bracket 309 more stable.

[0023] Furthermore, a compression spring 315 is fitted on the surface of the sliding column 314, and the lower ends of the multiple compression springs 315 abut against the surface of the support frame 309. The compression springs 315 facilitate the compression of the support frame 309, so that the support frame 309 abuts tightly against the upper end of the threaded column 317.

[0024] Working principle: During use, the uniform speed retraction component 3 causes the output end of the motor 305 to rotate at a uniform speed. Through the cooperation of the synchronous pulley 306 and the synchronous belt 307, the rotating column 301 and the winding frame 302 rotate at a uniform speed. The uniform speed rotation of the winding frame 302 causes the winding rope 303 to be wound at a uniform speed. The uniform speed winding of the winding rope 303 causes the rotary spraying mechanism 2 to move at a uniform speed on the inner wall of the steel pipe. The uniform speed movement of the rotary spraying mechanism 2 facilitates the uniform spraying of the inner wall of the steel pipe. By uniformly spraying the inner wall of the steel pipe, the anti-corrosion effect of the inner wall of the composite steel pipe is improved.

[0025] The mounting bracket 308, support bracket 309, and constraint column 311 work together to facilitate the insertion of constraint column 311 into the inner wall of constraint tube 310 as the output shaft 304 continues to retract when the rotary spraying mechanism 2 reaches the end of the spraying process. This facilitates the reception and support of the rotary spraying mechanism 2, thereby improving the integrity of the coating on the inner wall of the steel pipe and providing better anti-corrosion effect for the inner wall of the steel pipe.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
