Description

Technical Field

[0001] This utility model relates to the field of plumbing steel pipe processing technology, and in particular to a rust removal device for multi-specification steel pipes. Background Technology

[0002] Plumbing steel pipes refer to steel pipes used in plumbing systems. They are mainly used in water supply and drainage systems for houses, buildings, and various industrial systems, including hot and cold water supply, water supply and drainage pipes, etc. When plumbing steel pipes are used, their surface is prone to rust due to the influence of the external environment. In order to ensure the performance of plumbing steel pipes, they are generally treated with rust removal equipment.

[0003] Existing steel pipe rust removal equipment uses a conveying mechanism and a grinding mechanism to convey and grind round plumbing steel pipes respectively. Although this can achieve rapid rust removal, the fixed positions of the conveying and grinding mechanisms mean that grinding wheels of the appropriate size must be replaced when processing round plumbing steel pipes of different diameters. This operation is time-consuming and labor-intensive, which can affect the rust removal efficiency of round plumbing steel pipes. Therefore, a multi-specification steel pipe rust removal equipment is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-specification steel pipe rust removal device, which can solve the problem that due to the fixed positions of the conveying mechanism and the grinding mechanism, when processing round plumbing steel pipes of different diameters, it is necessary to change the grinding wheel of the corresponding size, which is time-consuming and laborious, and thus easily affects the rust removal efficiency of round plumbing steel pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification steel pipe rust removal device, including a support frame and a conveying module, and further comprising:

[0006] Support columns, which are arranged on the upper part of the bracket, and there are four support columns;

[0007] A support plate is disposed at the upper end of four support columns;

[0008] A lifting plate, which is slidably disposed on the outer surface of four support columns;

[0009] A rust removal mechanism is provided on the upper part of the support plate and is rotatably connected to the lifting plate.

[0010] An adjustment mechanism is rotatably mounted on the inner surface of the support plate, the adjustment mechanism is hinged to the lifting plate, and the adjustment mechanism is fixedly connected to the rust removal mechanism.

[0011] Preferably, the rust removal mechanism includes a motor mounted on the upper part of the support plate, the output end of the motor being provided with a first rotating shaft, the first rotating shaft being rotatably connected to the support plate, the inner surface of the first rotating shaft being slidably connected with a second rotating shaft, the second rotating shaft being rotatably connected to a lifting plate, the outer surface of the second rotating shaft being provided with a driving bevel gear, the outer surface of the driving bevel gear being provided with a driven bevel gear, the inner surface of the driven bevel gear being provided with a third rotating shaft, the third rotating shaft being rotatably connected to the lifting plate, and the outer surface of the third rotating shaft being provided with a grinding wheel.

[0012] Preferably, the outer surface of the rotating shaft three located on one side of the grinding wheel is provided with a cleaning brush.

[0013] Preferably, the inner surface of the lifting plate is rotatably connected to two stabilizing wheels, and the grinding wheel is located between the two stabilizing wheels.

[0014] Preferably, the adjusting mechanism includes a reciprocating lead screw rotatably disposed on the inner surface of the support plate, a sliding plate threadedly connected to the outer surface of the reciprocating lead screw, the sliding plate being slidably connected to the support plate, a connecting rod hinged to the outer surface of the sliding plate, the connecting rod being hinged to the lifting plate, a one-way bevel gear disposed on the outer surface of the reciprocating lead screw located on one side of the sliding plate, a transmission bevel gear meshing with the outer surface of the one-way bevel gear, and the transmission bevel gear being fixedly connected to the rotating shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, through the configuration of a lifting plate, rust removal mechanism, adjustment mechanism, cleaning brush, and stabilizing wheel, can automatically and flexibly adjust according to the actual diameter of the round plumbing steel pipe. During processing, the motor in the rust removal mechanism can be started according to the actual diameter of the round plumbing steel pipe. The motor output reverses, driving the one-way bevel gear, reciprocating screw, slide plate, and connecting rod in the adjustment mechanism. This moves the rotating shaft two, driving bevel gear, driven bevel gear, rotating shaft three, grinding wheel, cleaning brush, and stabilizing wheel in the rust removal mechanism to a suitable height. Then, the motor output rotates forward, ensuring that the structural height remains unchanged after moving to the suitable height. At the same time, the grinding wheel and cleaning brush rotate to grind and remove rust from the conveyed round plumbing steel pipe and clean the surface debris after rust removal. The stabilizing wheel, which contacts the upper part of the round plumbing steel pipe, stabilizes it and prevents the round plumbing steel pipe from shaking, thereby ensuring the rust removal quality of the round plumbing steel pipe. There is no need to change grinding wheels of different sizes, which saves operation time and ensures the rust removal efficiency of round plumbing steel pipes of different specifications.

[0026] 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.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution:

[0028] A multi-specification steel pipe rust removal device includes a support frame 1 and a conveying module 2, and also includes:

[0029] Support column 3, the support column 3 is set on the upper part of the bracket 1, and there are four support columns 3;

[0030] Support plate 4 is set at the upper end of the four support columns 3;

[0031] The lifting plate 5 is slidably disposed on the outer surface of the four support columns 3;

[0032] Rust removal mechanism 6 is located on the upper part of support plate 4 and is rotatably connected to lifting plate 5.

[0033] Adjustment mechanism 7 is rotatably mounted on the inner surface of support plate 4. Adjustment mechanism 7 is hinged to lifting plate 5 and fixedly connected to rust removal mechanism 6.

[0034] The conveying module 2 consists of a transmission wheel, transmission roller, pulley, belt, motor and other structures. It is used for conveying steel pipes during the rust removal process of round plumbing steel pipes. It can realize the function of rotating the round plumbing steel pipes during the conveying process, which is the existing technology.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rust removal mechanism 6 includes a motor 61 mounted on the upper part of the support plate 4. The output end of the motor 61 is provided with a rotating shaft 62, which is rotatably connected to the support plate 4. A rotating shaft 63 is slidably connected to the inner surface of the rotating shaft 62, and the rotating shaft 63 is rotatably connected to the lifting plate 5. A driving bevel gear 64 is provided on the outer surface of the rotating shaft 63, and a driven bevel gear 65 is provided on the outer surface of the driving bevel gear 64. A rotating shaft 66 is provided on the inner surface of the driven bevel gear 65, and the rotating shaft 66 is rotatably connected to the lifting plate 5. A grinding wheel 67 is provided on the outer surface of the rotating shaft 66.

[0036] Specifically, such as Figure 3 and Figure 4 As shown, the outer surface of the rotating shaft 66 located on one side of the grinding wheel 67 is equipped with a cleaning brush 8, which can clean the debris from the surface of the round plumbing steel pipe after rust removal, thereby facilitating the subsequent processing of the round plumbing steel pipe.

[0037] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner surface of the lifting plate 5 is rotatably connected to two stabilizing wheels 9, and the grinding wheel 67 is located between the two stabilizing wheels 9. During the processing, the round water heating steel pipe can be stabilized to prevent the round water heating steel pipe from shaking during the processing, thereby ensuring the rust removal quality of the round water heating steel pipe.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustment mechanism 7 includes a reciprocating screw 71 rotatably disposed on the inner surface of the support plate 4. A slide plate 72 is threadedly connected to the outer surface of the reciprocating screw 71. The slide plate 72 is slidably connected to the support plate 4. A connecting rod 73 is hinged to the outer surface of the slide plate 72. The connecting rod 73 is hinged to the lifting plate 5. A one-way bevel gear 74 is disposed on the outer surface of the reciprocating screw 71 located on one side of the slide plate 72. A transmission bevel gear 75 is meshed with the outer surface of the one-way bevel gear 74. The transmission bevel gear 75 is fixedly connected to the rotating shaft 62.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the pitch of the reciprocating lead screw 71 is 3mm. Using a reciprocating lead screw 71 with a pitch of 3mm can provide better transmission efficiency and stability.

[0040] Specifically, such as Figure 3 and Figure 4 As shown, the first rotating shaft 62 and the support plate 4, the second rotating shaft 63 and the lifting plate 5, the third rotating shaft 66 and the lifting plate 5, the reciprocating screw 71 and the support plate 4, and the stabilizing wheel 9 and the lifting plate 5 are all rotatably connected by bearings, which can reduce rotational friction and facilitate the rotation of the first rotating shaft 62, the second rotating shaft 63, the third rotating shaft 66, the reciprocating screw 71 and the stabilizing wheel 9.

[0041] Working principle: When in use, according to the diameter of the round water heating steel pipe, start the motor 61. The output end of the motor 61 reverses, which can drive the rotating shaft 62 to reverse. Then, through the meshing of the transmission bevel gear 75 and the one-way bevel gear 74, the reciprocating screw 71 is driven to rotate, causing the slide plate 72 and its connected connecting rod 73 to move, thereby driving the lifting plate 5 to move up or down. The movement of the lifting plate 5 will cause the rotating shaft 63, the driving bevel gear 64, the driven bevel gear 65, the rotating shaft 66, the grinding wheel 67, the cleaning brush 8 and the stabilizing wheel 9 to move up or down to the appropriate position as a whole. During this process, the rotating shaft 63 slides on the inner surface of the rotating shaft 62, and the two always maintain a sliding connection in the vertical direction.

[0042] Next, the circular plumbing steel pipe is placed on the conveying module 2 for transport. During transport, the circular plumbing steel pipe rotates. Simultaneously, the motor 61 is started. The output of the motor 61 rotates forward, driving the first rotating shaft 62 to rotate forward, causing the transmission bevel gear 75 to rotate forward and the second rotating shaft 63 to rotate horizontally. The horizontal rotation of the second rotating shaft 63 then drives the driving bevel gear 64 to rotate, thereby driving the driven bevel gear 65 to rotate, causing the third rotating shaft 66 to rotate. This, in turn, drives the grinding wheel 67 and the cleaning brush 8 to rotate, thus cleaning the circular plumbing steel pipe. The heating steel pipe undergoes grinding and rust removal, as well as surface debris cleaning after rust removal. During this process, when the transmission bevel gear 75 rotates forward, the one-way bevel gear 74 remains stationary. This allows the lifting plate 5, rotating shaft 2 63, driving bevel gear 64, driven bevel gear 65, rotating shaft 3 66, grinding wheel 67, cleaning brush 8, and stabilizing wheel 9 to be maintained at appropriate heights. Simultaneously, when the round heating steel pipe is being ground and rust removed, the stabilizing wheel 9 contacts the upper part of the round heating steel pipe, providing a stabilizing effect and preventing the round heating steel pipe from shaking during the grinding and rust removal process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
