Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a rust removal device for steel pipes used in engineering construction. Background Technology

[0002] Engineering construction refers to the process of transforming various resources into fixed assets through a series of organized activities such as planning, design, construction, installation, and commissioning. It involves building or renovating engineering entities with specific functions to meet the needs of social production, life, and public services. Steel pipe rust removal devices for engineering construction are specialized equipment or systems designed to remove rust, scale, oil stains, and other deposits from the surface of steel pipes in the engineering construction field. They treat the surface of steel pipes through mechanical, chemical, physical, or composite methods to restore the metallic color of the steel pipes, improve surface smoothness, and provide standard-compliant surface conditions for subsequent welding, painting, and installation processes, thereby ensuring the structural performance, corrosion resistance, and service life of the steel pipes.

[0003] Existing steel pipe rust removal equipment is inconvenient to remove rust evenly from all sides of the steel pipe. It can only remove rust little by little in certain areas. This localized rust removal method results in uneven rust removal on the surface of the steel pipe, which affects the quality of subsequent processing or use.

[0004] Therefore, a rust removal device for steel pipes used in engineering construction is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned rust removal device for steel pipes used in engineering construction, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a steel pipe rust removal device for engineering construction, which solves the problem that "existing steel pipe rust removal devices are inconvenient to remove rust evenly from all directions of the steel pipe when in use, and can only remove rust little by little in local areas of the steel pipe. This localized rust removal method results in uneven rust removal on the surface of the steel pipe, affecting the quality of subsequent processing or use".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rust removal device for steel pipes used in engineering construction, comprising:

[0009] A processing table, on the top surface of which a steel pipe is fixedly installed;

[0010] The rust removal unit is placed above the processing table. The rust removal unit includes a gear, a gear ring, a rust removal brush plate, and a rubber conveyor wheel. Under the rotation restriction of the gear, the gear ring is driven to rotate, and the rust removal brush plate inside the gear ring rotates to grind and remove rust from the steel pipe. Under the restriction of the rotating rubber conveyor wheel, the steel pipe can be conveyed during the grinding and rust removal process to achieve a continuous grinding and rust removal effect.

[0011] A limiting unit is placed outside the rust removal unit. The limiting unit includes opposing threaded rods and conveying rollers. The opposing threaded rods are rotated to make the two conveying rollers move in opposite directions to clamp and convey the steel pipe. With the support of the processing table, the rust removal unit and the limiting unit can stably convey, grind and remove rust from the steel pipe to achieve continuous grinding and rust removal effect.

[0012] As a preferred embodiment of the rust removal device for steel pipes used in engineering construction described in this utility model, the rust removal unit includes a bracket fixedly installed on the top surface of the processing table, a motor fixedly installed on the top surface of the bracket, a rotating rod fixedly installed at the output end of the motor, a gear fixedly sleeved on the outer wall of the rotating rod, a gear ring meshing on the outer wall of the gear, and a limiting ring rotatably connected to the outer side of the gear ring.

[0013] As a preferred embodiment of the rust removal device for steel pipes used in engineering construction described in this utility model, a telescopic rod is fixedly installed on the inner wall of the gear ring, and a rust removal brush plate is fixedly installed at the end of the telescopic rod.

[0015] As a preferred embodiment of the rust removal device for steel pipes used in engineering construction described in this utility model, the rust removal brush plate is arranged in an arc shape, and there are six rust removal brush plates distributed around the center of the toothed ring. Under the constraint of the arc-shaped rust removal brush plate, when it rotates, it can grind and remove rust from all directions of the steel pipe.

[0016] As a preferred embodiment of the rust removal device for steel pipes used in engineering construction according to this utility model, the limiting unit includes a counter-threaded rod rotatably connected to the top surface of the processing table, a sleeve block is sleeved on the outer wall of the counter-threaded rod, and a limit rod is slidably provided inside the sleeve block on the side away from the counter-threaded rod.

Under the constraint of the rotating conveying rollers, the steel pipe can be smoothly conveyed.

[0019] The beneficial effects of this utility model are as follows: When steel pipes need to be derusted during engineering construction, the limiting unit clamps and transports the steel pipe into the gear ring. The motor is started, and the rotating rod drives the gear to rotate. The gear ring rotates stably under the action of the limiting ring. At the same time, the telescopic rod pushes the derusting brush plate to contact the outer wall of the steel pipe. The gear ring drives the brush plate to rotate to remove rust. When the rotating rod rotates, it drives the worm gear, which causes the worm, rotating shaft and rubber conveying wheel to rotate. The rubber wheel transports the steel pipe. The rubber wheel and the telescopic rod can adapt to steel pipes of different thicknesses to achieve grinding and conveying.

[0020] When removing rust, place the steel pipe between two conveying rollers, rotate the opposing threaded rod, and the sleeve block slides along the limit rod, driving the two conveying rollers to move in opposite directions to clamp the steel pipe. With the help of rubber conveying wheels, it can be conveyed for grinding and rust removal. Attached Figure Description

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a rust removal device for steel pipes used in engineering construction, comprising:

[0035] A processing table 100, on the top surface of which a steel pipe 101 is fixedly installed;

[0036] Rust removal unit 200 is placed above processing table 100. Rust removal unit 200 includes gear 204, gear ring 205, rust removal brush 208 and rubber conveyor wheel 212. Under the rotation restriction of gear 204, it drives gear ring 205 to rotate. Rust removal brush 208 inside gear ring 205 rotates to grind and remove rust from steel pipe 101. Under the restriction of rotating rubber conveyor wheel 212, it can convey steel pipe 101 during the grinding and rust removal process to achieve continuous grinding and rust removal effect.

[0037] The limiting unit 300 is located outside the rust removal unit 200. The limiting unit 300 includes opposing threaded rods 301 and conveying rollers 305. It is used to rotate the opposing threaded rods 301 so that the two conveying rollers 305 move in opposite directions to clamp and convey the steel pipe 101.

[0038] When in use, with the support of the processing table 100, the rust removal unit 200 and the limiting unit 300 can stably convey, grind and remove rust from the steel pipe 101 to achieve continuous grinding and rust removal effect.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0041] The rust removal unit 200 includes a bracket 201 fixedly installed on the top surface of the processing table 100. A motor 202 is fixedly installed on the top surface of the bracket 201. A rotating rod 203 is fixedly installed at the output end of the motor 202. A gear 204 is fixedly sleeved on the outer wall of the rotating rod 203. A gear ring 205 meshes with the outer wall of the gear 204. A limiting ring 206 is rotatably connected to the outer side of the gear ring 205. A telescopic rod 207 is fixedly installed on the inner wall of the gear ring 205. A rust removal brush plate 208 is fixedly installed at the end of the telescopic rod 207. A worm gear 209 is fixedly installed at the end of the rotating rod 203. A worm 210 meshes with the outer wall of the worm gear 209. A rotating shaft 211 is fixedly installed on the side wall of the worm 210. A rubber conveyor wheel 212 is fixedly installed on the outer wall of the rotating shaft 211. A vertical plate 213 is provided on the side of the rubber conveyor wheel 212.

[0042] Among them, the rust removal brush plate 208 is set in an arc shape, and there are six rust removal brush plates 208, which are distributed in a circle around the center of the toothed ring 205. Under the constraint of the arc-shaped rust removal brush plate 208, when it rotates, it can grind and remove rust from all directions of the steel pipe 101.

[0043] During use, when rust removal of the steel pipe 101 is required during engineering construction, it is clamped and conveyed into the gear ring 205 by the limiting unit 300. At this time, the motor 202 is started, and the rotating rod 203 fixedly installed at its output end rotates accordingly. The rotating rod 203 drives the gear 204 to rotate. Since the side wall of the gear ring 205 is rotatably connected to the limiting ring 206 fixedly installed on the top surface of the processing table 100, under its restriction, the rotating gear 204 drives the gear ring 205 to rotate stably. At this time, the telescopic rod 207 is activated, which pushes the rust removal brush 208, so that the rust removal brush 208 contacts the outer wall of the steel pipe 101. The rotating gear ring 205 drives the rust removal brush 208 to rotate. The rotation of the rotating rod 203 removes rust from the outer wall of the steel pipe 101. When the rotating rod 203 rotates, the worm gear 209 fixedly installed at its end rotates accordingly. Since the end of the vertical plate 213 is fixedly installed on the top surface of the processing table 100, and the outer wall of the rotating shaft 211 is rotatably connected to the inside of the vertical plate 213, under its constraint, the rotating worm gear 209 drives the worm 210 to rotate accordingly. The worm 210 drives the rotating shaft 211 and the rubber conveyor wheel 212 to rotate. The rubber conveyor wheel 212 conveys the steel pipe 101 being ground. Since the rubber conveyor wheel 212 is a rubber wheel, under its constraint, it can adapt to steel pipes 101 of different thicknesses in conjunction with the telescopic rod 207, so as to grind and convey them.

[0044] Example 3

[0045] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0046] The limiting unit 300 includes a counter-threaded rod 301 rotatably connected to the top surface of the processing table 100. A sleeve block 302 is sleeved on the outer wall of the counter-threaded rod 301. A limit rod 306 is slidably provided inside the sleeve block 302 on the side away from the counter-threaded rod 301. A vertical block 303 is fixedly installed on the side wall of the sleeve block 302. A rotating column 304 is rotatably connected inside the vertical block 303. A conveying roller 305 is fixedly installed at the end of the rotating column 304.

[0047] The end of the conveying roller 305 is rotatably connected to the side wall of the vertical block 303. There are four conveying rollers 305, which are divided into two groups and symmetrically distributed around the center line of the top surface of the processing table 100. Under the constraint of the rotating conveying rollers 305, the steel pipe 101 can be smoothly conveyed.

[0048] When using the steel pipe 101 to remove rust, it is placed between two conveying rollers 305. At this time, the opposing threaded rod 301 is rotated. Since the inner part of the sleeve block 302 is slidably set with the outer wall of the limiting rod 306, under its restriction, the rotating opposing threaded rod 301 can drive the two sleeve blocks 302 to move in opposite directions, so that the conveying rollers 305 clamp the steel pipe 101. With the help of the rubber conveying wheel 212 in the rust removal unit 200, the steel pipe 101 can be conveyed, ground and rust removed.

[0049] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
