[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figure 1-Figure 3 The present invention provides a technical solution: a steel pipe rust remover, comprising a bottom plate 1, a working box 2 is fixedly connected to the top of the bottom plate 1, a rotating shaft 3 is rotatably connected to the bottom of the inner wall of the working box 2, a telescopic rod 4 is fixedly connected to the inner wall of the rotating shaft 3, and a connecting mechanism 6 is provided at one end of the telescopic rod 4 away from the working box 2, and further comprising: The positioning mechanism 5 includes a connecting ring 501 fixedly connected to the surface of the telescopic rod 4, a propeller 502 fixedly connected to the top of the connecting ring 501, telescopic membranes 504 are slidably connected in the slots on both sides of the connecting ring 501, and the end of the telescopic membrane 504 away from the connecting ring 501 is fixedly connected to a connecting arm 505, and the inner wall of the propeller 502 is slidably connected to a pushing belt 503, and the end of the pushing belt 503 away from the propeller 502 is fixedly connected to the surface of the connecting arm 505, and the end of the connecting arm 505 away from the telescopic membrane 504 is provided with a buffer component 506.

[0023] The buffer assembly 506 includes a positioning block 5061 fixedly connected to one end of the connecting arm 505, and air intake blocks 5062 fixedly connected to both sides of the positioning block 5061. An air intake hole is opened inside the air intake block 5062, and compressed gas is injected inside. When compressed by one end of the compression block 5063, its internal space will be compressed to discharge the gas outward. The inner wall of the air intake block 5062 is slidably connected to the compression block 5063, and the end of the compression block 5063 away from the air intake block 5062 is fixedly connected to a contact ring 5064. A plurality of magnetic blocks are fixed on the surface of the contact ring 5064, and the magnetic blocks can generate magnetic adsorption with the inner wall of the steel pipe, so that the positioning block 5061 is adsorbed on the inner wall of the steel pipe. The contact ring 5064 has the characteristics of bending and expansion. When subjected to external pressure, it will expand and contract inward. The bottom of the inner wall of the positioning block 5061 is fixedly connected to the air intake pipe 5065.

[0024] The working method of the first embodiment is as follows: first, the telescopic device inside the working box 2 is started to drive the telescopic rod 4 to telescope outward into the inner wall of the steel pipe, and one end of the air inlet pipe 5065 is plugged into the surface of the absorption pipe 6036, so that the positioning block 5061 is fixed to the surface of the rotating ring 601, and the propeller 502 is remotely started to drive the pushing belt 503 inside it to telescope outward, and the connecting arm 505 is pushed by the outward telescopic pushing belt 503, so that the connecting arm 505 is telescoped outward through the telescopic membrane 504. When the telescopic membrane 504 is telescoped outward and drives the connecting arm 505 to move to the inner wall of the steel pipe, it will be connected to the absorption pipe 6036 and the air inlet pipe. 5065 are fixed between them to stretch the buffer tube 6032 outward, and the contact ring 5064 will first contact with the inner wall of the steel pipe. While the contact ring 5064 will squeeze the inner wall of the steel pipe, it will also squeeze the compression block 5063 connected at both ends of the contact ring 5064, so that one end of the compression block 5063 is extended and retracted into the interior of the air intake block 5062, and the internal space of the air intake block 5062 is compressed by the compression block 5063, so that the internal gas of the compression block 5063 enters the air intake pipe 5065 through the internal passage of the positioning block 5061, and the rust removal device on the inner wall of the steel pipe can be automatically positioned to the inner wall of the steel pipe for steel pipes with different diameters.

[0025] Example 2: Based on Example 1, continue to refer to Figure 4-Figure 6 The connecting mechanism 6 includes a rotating ring 601, which is fixedly connected to one end of the telescopic rod 4. A telescopic cavity 602 is opened on one side of the rotating ring 601, and a grinding component 603 is arranged at the bottom of the inner wall of the telescopic cavity 602.

[0026] The grinding assembly 603 includes a storage box 6031, which is fixedly connected to the bottom of the inner wall of the telescopic chamber 602. A buffer tube 6032 is fixedly connected to the top of the storage box 6031. An impact rod 6033 is fixedly connected to the surface of the buffer tube 6032. Sand is stored in the storage box 6031. When the internal space of the buffer tube 6032 is compressed, a pressure difference is formed with the outside, thereby generating a negative pressure suction force inside, and absorbing the sand inside the storage box 6031 and discharging it outward. The end of the impact rod 6033 away from the buffer tube 6032 is fixedly connected to both sides of the storage box 6031. The buffer tube 6032 is far away from the impact rod 6033. A connecting block 6034 is fixedly connected to one end of the storage box 6031, and a discharge hole and a passage are provided inside the connecting block 6034. The discharge hole extends into the interior of the spray block 6042 through the connection between the buffer tube 6032 and the connecting block 6034, and the passage extends into the interior of the compression chamber 6041 from the connection between the absorption tube 6036 and the connecting block 6034. A grinding block 6035 is fixedly connected to the surface of the connecting block 6034, and an absorption tube 6036 is fixedly connected to the surface of the connecting block 6034. Spraying assemblies 604 are arranged on both sides of the inner wall of the connecting block 6034, and a cleaning mechanism 7 is arranged at the bottom of the connecting block 6034.

[0027] The spray assembly 604 includes a compression chamber 6041, which is fixedly connected to the top of the connecting block 6034. The inner wall of the compression chamber 6041 is slidably connected with a compression ring 6043. The end of the compression ring 6043 away from the compression chamber 6041 is fixedly connected with a spray block 6042. The two sides of the spray block 6042 are rotatably connected to the two sides of the inner wall of the connecting block 6034 through a rotating shaft. The surface of the spray block 6042 is fixedly connected with an ejection ring 6044. An air groove is provided at the connection between one end of the compression ring 6043 and the spray block 6042. When the interior of the compression ring 6043 is compressed, the gas inside it will penetrate into the interior of the spray block 6042 from the air groove.

[0028] The working method of the second embodiment is as follows: when the buffer tube 6032 is pulled by the positioning block 5061 and drives the grinding block 6035 to move to the surface of the rust layer on the inner wall of the steel pipe, the three-phase motor inside the starting working box 2 drives the rotating shaft 3 to rotate, and the telescopic rod 4 is driven to rotate through the rotating shaft 3. When the telescopic rod 4 rotates, it drives the rotating ring 601 to rotate, and the grinding block 6035 on the surface of the rotating ring 601 rotates to scrape the rust layer on the inner wall of the steel pipe, and the rotation of the telescopic rod 4 also drives the contact ring 5064 on the surface of the positioning block 5061 to rub against the inner wall of the steel pipe, and squeeze the contact ring 5064, so that the surface of the contact ring 5064 is pressurized and expands inward and presses the pressure. The shrink block 5063 generates extrusion, thereby driving one end of the compression block 5063 to compress the internal space of the air intake block 5062, and the contact ring 5064, due to continuous frictional contact with the inner wall of the steel pipe, will cause the surface of the contact ring 5064 to continuously bend and expand and compress the air intake block 5062, and the multiple streams of gas generated by the continuous compression of the internal space of the air intake block 5062 will be discharged into the absorption pipe 6036 through the intake pipe 5065, and the gas injected into the absorption pipe 6036 will enter the compression chamber 6041 through the internal passage of the connecting block 6034, and the gas will be injected into the compression ring 6043 from the compression chamber 6041, which will drive the compression ring 6043 to continuously expand and contract outward. , and pushes the spray block 6042 through the compression ring 6043 that continuously expands and contracts outward, so that the spray block 6042 rotates up and down on both sides of the inner wall of the connecting block 6034. When the grinding block 6035 and the rust layer on the inner wall of the steel pipe are derusted, the pressure generated by the grinding block 6035 will compress the buffer tube 6032 multiple times. When the internal space of the buffer tube 6032 is compressed, negative pressure suction will be formed, so that the sand inside the storage box 6031 is absorbed by the impact rod 6033 and discharged into the spray block 6042 through the internal discharge hole of the connecting block 6034. When the spray block 6042 swings up and down, the compression ring 6043 is squeezed, which makes the compression ring 6043 A part of the gas rushes into the interior of the spray block 6042, and the gas pushes the sand particles inside the spray block 6042, so that the sand particles are sprayed out from the interior of the spray ring 6044. When the grinding block 6035 removes rust from the rust layer on the inner wall of the steel pipe, due to the phenomenon that the rust layer on the inner wall of the steel pipe has different thicknesses, while the rust layer is being removed by the grinding block 6035, the sand particles sprayed outward by the spray rings 6044 on both sides are used to impact and cut the rust layer on the inner wall of the steel pipe. The sand particles can remove the rust layer without damaging the inner wall of the steel pipe. At the same time, when the rust layer is completely scraped off by the sand particles, the rust removal efficiency will be reduced due to the excessive thickness of the rust layer on the inner wall of the steel pipe.

[0029] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8The cleaning mechanism 7 includes a shrink disk 701, which is fixedly connected to the bottom of the connecting block 6034. The surface of the shrink disk 701 is fixedly connected to a connecting frame 702. Both sides of the inner wall of the connecting frame 702 are rotatably connected to a connecting shaft 703 through a rotating shaft. A pipeline is opened inside the connecting shaft 703 to store the rust layer. A material collection ring 704 is fixedly connected to the surface of the connecting shaft 703, and a friction component 705 is arranged on the surface of the connecting shaft 703.

[0030] The friction assembly 705 includes a tightening bag 7051, one end of which is fixedly connected to one end of the connecting shaft 703, and an extrusion ring 7052 is fixedly connected to one end of the connecting shaft 703. The tightening bag 7051 is made of a soft material that can be expanded and contracted inside and outside, and a negative pressure cavity is provided inside. When subjected to external compression, the negative pressure cavity will shrink inward and form a pressure difference with the outside, thereby absorbing the rust layer inside the connecting shaft 703 into the interior. The end of the extrusion ring 7052 away from the connecting shaft 703 is fixedly connected to the surface of the tightening bag 7051, and a telescopic belt 7053 is fixedly connected to the surface of the connecting shaft 703. The end of the telescopic belt 7053 away from the connecting shaft 703 is fixedly connected to a cleaning claw 7054, and cleaning blocks are provided on both sides of the cleaning claw 7054. The rust layer on the inner wall of the grinding block 6035 can be scraped off by the cleaning blocks on both sides.

[0031] The working method of the third embodiment is as follows: when the grinding block 6035 is removing rust from the rust layer on the inner wall of the steel pipe, the servo motor on one side of the connecting frame 702 is remotely started to drive the connecting shaft 703 to rotate on its inner wall. While rotating, pressure is applied to the extrusion rings 7052 at both ends of the connecting shaft 703, driving one end of the extrusion ring 7052 to produce inward and outward expansion and contraction on the inner wall of the connecting shaft 703, and through one end of the extrusion ring 7052 that expands inward and outward, the tightening bag 7051 is squeezed, so that the tightening bag 7051 expands and contracts inward, thereby compressing the inside of the tightening bag 7051 and forming a negative pressure suction force, and the rust layer polished by the grinding block 6035 is absorbed into the inside of the connecting shaft 703 through the absorption groove on the surface of the receiving ring 704 on the surface of the connecting shaft 703, and finally the rust layer is absorbed into the inside of the tightening bag 7051 through the internal pipeline of the connecting shaft 703. The grinding block 6035 collects the rust flakes removed from the rust layer on the inner wall of the steel pipe to prevent them from being scattered on the inner wall of the steel pipe and being difficult to clean. When the connecting shaft 703 rotates, the telescopic belt 7053 on its surface will drive the cleaning claw 7054 to rotate. When the rotating telescopic belt 7053 rotates to the inner wall of the grinding block 6035, the rust layer scraped off from the inner wall of the grinding block 6035 will be cleaned by the cleaning claw 7054, thereby scraping off the rust layer adhered to the inner wall of the grinding block 6035. After the rust layer is cleaned out from the inner wall of the grinding block 6035, it will fall into the interior of the collecting ring 704, thereby absorbing the rust layer into the interior of the connecting shaft 703 through the collecting ring 704. When the grinding block 6035 is cleaning the rust layer, the rust layer adhered to the inner wall can be cleaned, thereby preventing the inner wall of the grinding block 6035 from being blocked, thereby reducing the rust removal efficiency of the inner wall of the steel pipe.
