A limit piston rod is slidably installed inside the limit sleeve, and a contact spring is connected between the bottom inner wall of the limit piston rod and the limit sleeve. The extended end of the limit piston rod is arranged outside the limit sleeve, and the extended end of the limit piston rod is connected to the outer wall of the side of the support back plate. A friction pad is arranged on the outer wall of the side of the support back plate.

[0006] Preferably, both the support back plate and the friction pad are of an arc structure, and the outer wall of the side of the friction pad is of an arc structure.

[0007] Preferably, there are two positioning seats. Support bottom plates are symmetrically arranged on the outer wall of the bottom end of one of the positioning seats.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-6As shown in the figure, a pipe surface rust removal device includes a support base 1, a positioning seat 2, and a support box 3: A positioning seat 2 is provided on the outer wall of the top end of the support base 1, a support box 3 is provided on the outer wall of the top end of the support base 1, a rotating support mechanism 4 is provided inside the positioning seat 2, a transmission control mechanism 6 is provided inside the support box 3, and a rust removal control mechanism 7 is provided above the transmission control mechanism 6. The rotating support mechanism 4 includes a driving motor 41, a transmission shaft 42, a support disk 43, a support ring 44, a limiting sleeve 45, a limiting piston rod 46, a resisting spring 47, a support back plate 48, and a friction pad 49. The inside of the positioning seat 2 is of a cavity structure, and a driving motor 41 is provided on the side inner wall of the positioning seat 2. The driving motor 41 is connected to one end of the transmission shaft 42, and the other end of the transmission shaft 42 is connected to the outer wall of the side of the support disk 43. A placement groove is opened on the side outer wall of the positioning seat 2, and the support disk 43 is rotatably installed inside the placement groove. A support ring 44 is provided on the outer wall of the side of the support disk 43, and limiting sleeves 45 are equally spaced and embedded around the inner wall of the side of the support ring 44. A limiting piston rod 46 is slidably installed inside the limiting sleeve 45. A resisting spring 47 is connected between the bottom inner wall of the limiting piston rod 46 and the limiting sleeve 45. The extending end of the limiting piston rod 46 is located outside the limiting sleeve 45, and the extending end of the limiting piston rod 46 is connected to the outer wall of the side of the support back plate 48. A friction pad 49 is provided on the outer wall of the side of the support back plate 48. There are two positioning seats 2. Support bottom plates 51 are symmetrically provided on the outer wall of the bottom end of one of the positioning seats 2. First threaded grooves 52 are symmetrically and penetratingly opened on the outer wall of the top end of the support bottom plates 51. Corresponding groups of second threaded grooves 53 are opened on the outer wall of the top end of the support base 1. The first threaded grooves 52 and the second threaded grooves 53 are threadedly installed with positioning bolts 54;

[0024] When it is necessary to position the pipe to be rust-removed inside the device, first, the second group of positioning seats 2 needs to be removed from above the device. When disassembling, only need to completely screw out the positioning bolt 54 from the inside of the first threaded groove 52 to remove it. Subsequently, the pipe to be rust-removed is abutted against the middle position of the three friction pads 49 of the first group of positioning seats 2. Then, the friction pads 49 automatically move to the side under the abutting force and drive the support back plate 48 to move. Subsequently, the movement of the support back plate 48 will automatically drive the limiting piston rod 46 to slide inside the limiting sleeve 45. At this time, the resisting spring 47 is in a contracted state under the extrusion of the limiting piston rod 46. When the pipe moves to fit with the outer wall of the side of the support disk 43, stop pushing the pipe. Then, the reaction force generated by the synchronous extrusion of the above-mentioned resisting spring 47 will automatically push the limiting piston rod 46 to move in the reverse direction. Then, the movement of the limiting piston rod 46 will automatically drive the support back plate 48 to move, so that the friction pads 49 are closely attached to the outer wall of the pipe. Thus, the positioning of one end of the pipe is completed;

[0025] When it is necessary to locate the other end of the pipeline, the principle is the same as above. Push the positioning seat 2 removed before installation horizontally to the side of the pipeline. The clamping principle is the same as above. Then, pass the positioning bolt 54 through the first thread groove 52 and screw it to the bottom end of the second thread groove 53 to complete the positioning and installation of the second positioning seat 2. Thus, the positioning effect of the pipeline is completed through the above process. It should be noted here that only one of the two groups of positioning seats 2 needs to install the driving motor 41 inside, and the other friction pad 49 assembly structure only assists in positioning and supporting the pipeline. When it is necessary to drive the pipeline to rotate to adapt to the subsequent rust remover spraying process for uniform feeding, at this time, only need to turn on the driving motor 41. Then, after the driving motor 41 is turned on, it will automatically drive the transmission shaft 42 to rotate and then drive the support disc 43 to rotate. Subsequently, when the support disc 43 rotates, it will automatically drive the support ring 44 to rotate. Since the above pipeline has been clamped in the middle position of the three friction pads 49, the rotation of the support ring 44 will automatically drive the pipeline to rotate.

[0026] The support back plate 48 and the friction pad 49 are both set as arc-shaped structures, and the outer side wall of the friction pad 49 is set as an arc-shaped structure. Here, setting the support back plate 48 and the friction pad 49 as arc-shaped structures makes their overall shape more conform to the shape of the pipeline, so as to facilitate stable clamping of it. Setting the outer side wall of the friction pad 49 as an arc-shaped structure makes it more convenient for the above pipeline to be inserted into the middle position of the three friction pads 49.

[0027] The transmission control mechanism 6 includes a control motor 61 and a reciprocating lead screw 62. The control motor 61 is arranged on the outer side wall of the support box 3. The output end of the control motor 61 is connected to one end of the reciprocating lead screw 62. The other end of the reciprocating lead screw 62 is rotatably installed on the inner side wall of the support box 3. A limit bar 63 is arranged in parallel on the side of the reciprocating lead screw 62. Both ends of the limit bar 63 are connected to the outer side wall of the support box 3. A limit block 64 is arranged through the reciprocating lead screw 62 and the limit bar 63. Limit bumps are symmetrically arranged on both outer side walls of the limit block 64, and the limit bumps are slidably installed on the inner side wall of the support box 3. An installation block is arranged on the top outer wall of the limit block 64;

[0028] As shown in the instruction manual appendix Figure 5As shown, the reciprocating lead screw 62 is only threaded in the middle position. By designing in this way, the transmission path of the subsequent liquid storage tank 71 is limited by controlling the distance of the threaded opening, thereby providing a guarantee for the subsequent spraying process on the basis of controlling the moving trajectory of the liquid storage tank 71, and avoiding the pollution caused by spraying the rust remover outside the pipeline. When it is necessary to control the transmission of the liquid storage tank 71 for mobile spraying, only the control motor 61 needs to be turned on at this time. When the control motor 61 is turned on, it will automatically drive the reciprocating lead screw 62 to rotate. Then, the rotation of the reciprocating lead screw 62 will automatically drive the limit block 64 to move. Due to the setting of the limit strip 63 here, when the reciprocating lead screw 62 rotates, it will only drive the limit block 64 to move along a reciprocating sliding trajectory in the horizontal direction. Then, the movement of the limit block 64 will automatically drive the installation block to move and then drive the liquid storage tank 71 to move.

[0029] The rust removal control mechanism 7 includes a liquid storage tank 71 and a micro pump 72. The top outer wall of the support box 3 is fitted with the liquid storage tank 71, and the bottom outer wall of the liquid storage tank 71 is connected to the top outer wall of the installation block. The micro pump 72 is installed on the bottom inner wall of the liquid storage tank 71. One end of the micro pump 72 is connected to one end of the diversion pipe 73, and the other end of the diversion pipe 73 is provided with a spray head 74, and the spray head 74 is inclined. When it is necessary to spray and remove rust on the pipeline with the rust remover stored in the liquid storage tank 71, only the micro pump 72 needs to be turned on at this time. When the micro pump 72 is turned on, it will automatically pump the rust remover in the liquid storage tank 71 into the inside of the diversion pipe 73, and then spray it onto the outside of the pipeline through the diversion of the diversion pipe 73 by the spray head 74, as shown in the attached Figure 6 As shown in the figure, a liquid injection pipe is conductively installed on the top outer wall of the liquid storage tank 71. When it is necessary to supplement the rust remover into the liquid storage tank 71, it can be directly filled into the device through the liquid injection pipe.

[0030] When the utility model is in use, when it is necessary to position the pipeline to be derusted inside the device, first, the second group of positioning seats 2 need to be removed from above the device. When disassembling, only need to completely screw out the positioning bolt 54 from the inside of the first thread groove 52 to remove it. Then, the pipeline to be derusted is abutted against the middle position of the three friction pads 49 of the first group of positioning seats 2. Then, the friction pads 49 automatically move to the side under the abutting force and drive the support back plate 48 to move. Subsequently, the movement of the support back plate 48 will automatically drive the limit piston rod 46 to slide inside the limit sleeve 45. At this time, the abutting spring 47 is in a contracted state under the extrusion of the limit piston rod 46. When the pipeline moves to fit against the outer side wall of the support disk 43, stop pushing the pipeline. Then, the reaction force generated by the synchronous extrusion of the above-mentioned abutting spring 47 will automatically push the limit piston rod 46 to move in the reverse direction. Then, the movement of the limit piston rod 46 will automatically drive the support back plate 48 to move, so that the friction pads 49 are closely attached to the outer wall of the pipeline. Thus, the positioning of one end of the pipeline is completed. When it is necessary to position the other end of the pipeline, the principle is the same. Horizontally push the positioning seat 2 removed before installation to the side of the pipeline. The clamping principle is the same as above. Then, pass the positioning bolt 54 through the first thread groove 52 and screw it to the bottom end of the second thread groove 53 to complete the positioning and installation of the second positioning seat 2. Thus, the positioning effect of the pipeline is completed through the above process. Here, it should be noted that only one of the above two groups of positioning seats 2 needs to install the drive motor 41 inside, and the other friction pad 49 assembly structure only assists in positioning and supporting the pipeline;

[0031] Subsequently, the drive motor 41, the control motor 61, and the micro pump 72 are synchronously started. When the drive motor 41 is started, it will automatically drive the transmission shaft 42 to rotate, and then drive the support disk 43 to rotate. Then, the rotation of the support disk 43 will automatically drive the support ring 44 to rotate. Since the above pipeline has been clamped in the middle position of the three friction pads 49, the rotation of the support ring 44 will automatically drive the pipeline to rotate;

[0032] When the control motor 61 is started, it will automatically drive the reciprocating lead screw 62 to rotate. Then, the rotation of the reciprocating lead screw 62 will automatically drive the limit block 64 to move. Here, due to the setting of the limit strip 63, when the reciprocating lead screw 62 rotates, it will only drive the limit block 64 to move along a reciprocating sliding track in the horizontal direction. Then, the movement of the limit block 64 will automatically drive the installation block to move and then drive the liquid storage tank 71 to move;

[0033] When the micro pump 72 is started, it will automatically pump the rust remover inside the liquid storage tank 71 into the inside of the diversion pipe 73, and then spray it onto the outside of the pipeline through the spray head 74 under the diversion of the diversion pipe 73. As shown in the attached Figure 6 of the specification, a liquid injection pipe is conductively installed on the top outer wall of the liquid storage tank 71. When it is necessary to replenish the rust remover into the liquid storage tank 71, directly inject it into the device through the liquid injection pipe

[0034] Thus, through the cooperation of the above working process, the effect of automatically rotating and spraying rust remover on the pipeline can be achieved. After subsequent rust removal, the pipeline can be cleaned again with clean water to ensure that there is no residue of rust remover on the outer wall of the pipeline;

[0035] It should be noted here that the above driving motor 41 and control motor 63 can be powered according to the existing operation technical means. Whether it is powered by a power supply component or an external wire, it belongs to the existing conventional operation technical means and will not be described in detail here.

[0036] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
