[0001] The utility model relates to the technical field of pipeline rust removal, in particular to a pipeline inner wall rust remover with an external clamping structure. Background Art

[0002] With the development of industrial technology, the requirements for the cleanliness of the inside of pipelines are getting higher and higher. Especially in the petroleum, chemical, water treatment and other industries, the cleanliness of the inner wall of the pipeline directly affects the service life and safety of the pipeline, and the traditional manual rust removal method, such as using a wire brush or an angle grinder, has problems such as low efficiency, high labor intensity, and unstable rust removal quality. This method not only cannot meet the needs of large-scale production, but also makes it difficult to ensure the consistency and stability of rust removal quality, so that the pipeline inner wall rust removal machine, as one of the important equipment, can achieve efficient rust removal of the inner wall of the pipeline through mechanized operation.

[0003] Most of the existing pipeline inner wall rust removal machines are composed of parts such as motors, chassis, pipeline brackets, guide rods, nylon steering wheels and rust removal units, so that during use, they can achieve efficient and stable rust removal of the pipeline inner wall through efficient motor drive, reasonable structural design and advanced rust removal technology. For example, the Chinese patent with publication number CN217097140U and name: Pipeline inner wall rust removal machine, through the mutual cooperation between the bottom plate and the cleaning mechanism, etc., while cleaning the inner wall of the pipeline, the wire brush can reciprocate left and right to avoid the occurrence of rust residue on the inner wall of the pipeline, and the problem of inadequate cleaning can be effectively improved. However, when it is cleaning, its cleaning structure will rub against the inner wall of the pipeline, so that the pipeline will produce a certain vibration, thereby affecting the stability of its pipeline placement, and then bringing a certain risk of rolling down to its rust removal operation. Therefore, the present application provides a pipeline inner wall rust removal machine with an external clamping structure to meet the demand. Utility Model Content

[0004] The purpose of the present application is to provide a pipeline inner wall rust remover with an external clamping structure, which solves the problem of friction force easily generated during rust removal in the prior art and achieves the purpose of stability during the rust removal operation.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a pipe inner wall rust remover with an external clamping structure, comprising a rust remover body, a cleaning assembly and a plurality of main clamping members arranged inside the rust remover body, a receiving cavity being opened on both sides of the cleaning assembly, and a driving member being slidably connected inside the receiving cavity, a free end of the driving member being connected to a side wall of the main clamping member, and the driving member being used to drive the main clamping member to move linearly, two driving motors being fixedly connected to the top of the rust remover body, and a driving shaft being fixedly connected to the output end of the driving motor, the driving shaft being inserted into the interior of the receiving cavity, and a driving gear being sleeved on the circumferential side of the driving shaft, a meshing gear plate being fixedly connected to the side wall of the driving member, and the driving gear and the meshing gear plate being matched.

[0006] Preferably, two electric slide rails are fixedly connected to opposite sides of the rust removal machine body, and a first electric push rod is fixedly connected to the sliding seat of the electric slide rail, and the free end of the first electric push rod is fixedly connected to the side wall of another main clamping member.

[0007] Preferably, the interior of the main clamping member is connected with a rubber pad via a plurality of rubber support plates, and the rubber pad is an arc-shaped structure.

[0008] Preferably, a concave frame is provided at the bottom of the rust removal machine body, and a supporting bottom plate is provided at the top of the concave frame.

[0009] Preferably, the bottom of the rust removal machine body is connected to a concave frame through a second electric push rod, a placement cavity is opened on the top of the concave frame, and a plurality of supporting cylinders are fixedly connected inside the placement cavity, and the top of the supporting cylinder is fixedly connected to the bottom of the supporting base plate.

[0010] Preferably, a plurality of buffer elastics are fixedly connected to the bottom of the supporting bottom plate, and the bottom ends of the buffer elastics are fixedly connected to the bottom of the concave frame.

[0011] Preferably, both ends of the supporting bottom plate are bent to form a bent portion, and a rubber pad is fixedly connected between the supporting bottom plate and the top of the bent portion.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. The utility model has a reasonable structure. By providing a main clamping member, the driving motor is controlled by an external controller before use, so that the driving motor drives the driving gear to rotate through the driving shaft under the action of its force. Since the driving gear and the meshing tooth plate are adapted to each other, when the driving gear rotates, its rotational force can be effectively converted into thrust and applied to the meshing tooth plate, so that the meshing tooth plate drives the driving member to slide along the accommodating cavity, thereby adjusting the driving member, so that the driving member can autonomously drive and adjust the position of the main clamping member, and finally change the direct size of the two main clamping members to meet the use of pipelines of different specifications, thereby ensuring the stability of the pipeline during use to a certain extent.

[0014] 2. In the utility model, by providing a supporting bottom plate, a concave frame and a supporting bottom plate, the bottom of the pipe can be effectively supported, thereby effectively sharing the supporting force of the pipe body, making it more stable during the rust removal operation, avoiding the possibility of the pipe body being too heavy and the main clamping part falling off, thereby improving its overall stability to a certain extent.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0027] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0028] It includes a rust removing body 1, wherein a cleaning assembly 2 and a plurality of main clamping members 5 are arranged inside the rust removing body 1, accommodating cavities 3 are opened on both sides of the cleaning assembly 2, and a driving member 4 is slidably connected inside the accommodating cavity 3, and the free end of the driving member 4 is connected to the side wall of the main clamping member 5, and the driving member 4 is used to drive the main clamping member 5 to move linearly, and two driving motors 6 are fixedly connected to the top of the rust removing body 1, and the output end of the driving motor 6 is fixedly connected to a driving shaft 7, the driving shaft 7 is inserted into the interior of the accommodating cavity 3, and a driving gear 8 is sleeved on the circumferential side of the driving shaft 7, and a meshing tooth plate 9 is fixedly connected to the side wall of the driving member 4, and the driving gear 8 and the meshing tooth plate 9 are adapted to each other.

[0029] Before use, the rust removal body 1 can be directly placed on a plane, so that the pipe to be inspected can be directly placed above the rust removal body 1, and the drive motor 6 can be controlled by an external controller, so that the drive motor 6 drives the drive gear 8 to rotate through the drive shaft 7 under the action of its force. Since the drive gear 8 and the meshing gear plate 9 are adapted to each other, when the drive gear 8 rotates, its rotational force can be effectively converted into thrust and applied to the meshing gear plate 9, so that the meshing gear plate 9 drives the drive member 4 to slide along the accommodating cavity 3, thereby adjusting the drive member 4, so that the drive member 4 can autonomously drive the adjustment of the position of the main clamping member 5, and finally change the direct size of the two main clamping members 5 to meet the use of pipes of different specifications, thereby to a certain extent, ensuring the stability of the pipe during use.

[0030] Two electric slide rails 10 are fixedly connected to opposite sides of the rust removal machine body 1 , and a first electric push rod 11 is fixedly connected to the sliding seat of the electric slide rail 10 . The free end of the first electric push rod 11 is fixedly connected to the side wall of another main clamping member 5 .

[0031] Before using it, the electric slide rail 10 can be directly controlled by an external controller according to the overall length of different pipes, so that the electric slide rail 10 drives the main clamping member 5 connected to it to slide horizontally inside the rust removal machine body 1 through the first electric push rod 11, thereby changing the spacing between several main clamping members 5 inside the rust removal machine body 1 to meet the use of pipes of different lengths. When adjusted to the appropriate position, the first electric push rod 11 can push the main clamping member 5 to move, so that several main clamping members 5 can respectively support and limit the middle part and two sections of the pipe body, thereby improving its overall stability.

[0032] The interior of the main clamping member 5 is connected to a rubber pad 13 via a plurality of rubber support plates 12 , and the rubber pad 13 is an arc-shaped structure.

[0033] When the main clamping member 5 is clamping the pipe, the rubber pad 13 will first contact the pipe body. At this time, the pipe body will push the rubber pad 13 under the action of its own size specifications, so that the rubber pad 13 will be subjected to force and transfer the force to the rubber support plate 12, so that the rubber support plate 12 and the rubber pad 13 will deform at the same time, which can meet the needs of clamping pipes of different specifications.

[0034] A concave frame 14 is disposed at the bottom of the rust removal machine body 1 , and a supporting bottom plate 15 is disposed at the top of the concave frame 14 .

[0035] During its use, the arrangement of the concave frame 14 and the supporting bottom plate 15 can effectively support the bottom of the pipe, thereby effectively sharing the supporting force of the pipe body, making it more stable during the rust removal operation, avoiding the possibility of the pipe body being too heavy and the main clamping member 5 falling off, thereby improving its overall stability to a certain extent.

[0036] The bottom of the rust removal machine body 1 is connected to a concave frame 14 through a second electric push rod 18. A placement cavity is opened at the top of the concave frame 14, and a plurality of supporting cylinders 16 are fixedly connected inside the placement cavity. The top of the supporting cylinder 16 is fixedly connected to the bottom of the supporting base plate 15.

[0037] Before use, the supporting cylinder 16 and the second electric push rod 18 can be directly controlled by an external controller according to the specific sizes of different pipes, so that the supporting cylinder 16 and the second electric push rod 18 can independently adjust the positions of the concave frame 14 and the supporting base plate 15, thereby meeting the use of pipes of different specifications and improving its overall flexibility.

[0038] A plurality of buffer springs 17 are fixedly connected to the bottom of the supporting bottom plate 15 , and the bottom ends of the buffer springs 17 are fixedly connected to the bottom of the concave frame 14 .

[0039] When the supporting cylinder 16 and the bending portion 19 are being adjusted, the buffer elastic 17 can effectively absorb and buffer the adjustment force, thereby preventing the supporting base plate 15 from being bumped during the adjustment.

[0040] Both ends of the supporting bottom plate 15 are bent to form a bent portion 19 , and a rubber pad 20 is fixedly connected between the supporting bottom plate 15 and the top of the bent portion 19 .

[0041] The provision of the bending portion 19 and the rubber pad 20 will increase the contact friction of the pipeline during clamping and rust removal to a certain extent, thereby improving the stability of pipeline placement.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
