Description

Technical Field

[0001] The invention relates to the technical field of pipeline rust removal, in particular to a rust removal device based on the outer wall of a pipeline and having a rapid adjustment function. Background Art

[0002] Since iron pipes have low processing costs and high strength, although they are prone to rust, they are still the first choice as water pipes in most pipeline projects. For iron pipes that are used for a long time, maintenance work such as rust removal is required.

[0003] The best way to remove rust from the outer wall of a pipe is to use high-pressure water jetting, which not only has a good rust removal effect but is also more environmentally friendly. However, using high-pressure water to remove rust from a pipe requires workers to hold a high-pressure water gun to flush the pipe. When the high-pressure water gun impacts the pipe, a recoil force will be generated, which can easily make the worker's hand-held high-pressure water gun unstable, especially when the pipe is located near a wall, on the ground or in a corner. It is even more inconvenient to use a high-pressure water gun to fully flush the inner side of the pipe. Therefore, a rust removal device is needed to solve this problem. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a rust removal device with a quick adjustment function based on the outer wall of the pipeline, which can be directly installed and fixed to the pipeline, and can remove rust from the pipeline surface while moving along the pipeline, and quickly adjust the position of the device, so that every position of the pipeline can be derusted without creating dead corners that are difficult to clean.

[0005] The technical solution to achieve the purpose of the present invention is: a rust removal device with a quick adjustment function based on the outer wall of a pipeline, comprising a first clamp, a second clamp and a hinge, the first clamp and the second clamp are hinged by a hinge, and an air-drying component is arranged on the first clamp and the second clamp, and the air-drying component comprises a first shell, the first shell is fixedly connected to the first clamp, and a water cavity and an air cavity are provided inside the first clamp and the second clamp, and a plurality of nozzles are fixedly connected to the first clamp and the second clamp, and a plurality of air jet holes are provided on the first clamp and the second clamp, and a groove is arranged inside the first shell, and a fan is fixedly connected inside the groove, and an air duct is arranged between the groove and the air cavity, and a water spraying component is arranged on the second clamp, and the water spraying component comprises a second shell, the second shell is fixedly connected to the second clamp, and a water tank and a telescopic motor are fixedly connected inside the second shell, and a piston is slidably connected inside the water tank, and the output shaft of the telescopic motor is fixedly connected to the piston, and a water pipe is fixedly connected between the water tank and the water cavity, and a sealing plug is arranged on the second shell, and a driving component is arranged inside the first shell and the second shell, and an auxiliary component is arranged on the first clamp and the second clamp.

[0006] Preferably, the driving assembly includes a power supply and a conductive rod, the two power supplies and the two conductive rods are respectively fixedly connected to the inside of the first shell and the second shell, and the two power supplies and the two conductive rods are respectively electrically connected to the telescopic motor and the fan.

[0007] Preferably, the driving assembly further comprises a pull rod and a conductive sheet, the two pull rods are respectively slidably connected to the first shell and the second shell, and the two conductive sheets are respectively fixedly connected to the two pull rods.

[0008] Preferably, the drive assembly also includes a limit rod and a spring, the two limit rods are fixedly connected to the two pull rods respectively, one end of the two springs are fixedly connected to the inner walls of the first shell and the second shell respectively, and the other ends of the two springs are fixedly connected to the two limit rods respectively.

[0009] Preferably, the auxiliary components include slide grooves, slide racks, rollers and compression springs, a plurality of the slide grooves are respectively opened on the first clamp and the second clamp, a plurality of the slide racks are respectively slidably connected to the inside of the plurality of slide grooves, a plurality of the rollers are respectively rotationally connected to the plurality of slide racks, and a plurality of the compression springs are respectively fixedly connected to the inner walls of the plurality of slide grooves and between the plurality of slide racks.

[0010] Preferably, two connecting pipes are provided between the first clamp and the second clamp, wherein one connecting pipe is connected between the two water chambers, and the other connecting pipe is connected between the two air chambers.

[0011] Preferably, the first fixture and the second fixture are symmetrically arranged, the plurality of nozzles are located at one end of the first fixture and the second fixture, and the plurality of air injection holes are located at the other end of the first fixture and the second fixture.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First: In the present invention, by setting an auxiliary component, when it is necessary to remove rust from the outer wall of the pipe, the first clamp and the second clamp can be moved onto the pipe, and the first clamp and the second clamp can be buckled together and locked to fix the device to the pipe. During this process, multiple rollers will press against the surface of the pipe, and then the slide will slide into the inside of the slide groove to compress the compression spring, so that the multiple rollers will press tightly against the surface of the pipe. When removing rust, the pull rod on the second shell is pulled by hand. Since the roller presses tightly against the surface of the pipe, when the pull rod is pulled, the pull rod moves first, driving the limit rod to move until the limit rod presses against the inner wall of the second shell, and then the pull rod continues to be pulled, and the pull rod will drive the second shell and the entire device to move.

[0014] Second: In the present invention, by setting a water spray component and a driving component, the device can be moved on the surface of the pipe. In the process of the pull rod being pulled and the limit rod being pressed against the inner wall of the second shell, the conductive sheet on the pull rod will move between the electrode of the power supply and the conductive rod. At this time, the power supply, the conductive rod and the conductive sheet are connected to form a complete circuit, and the telescopic motor is the load connected to this circuit. Therefore, the telescopic motor is started at this time to drive the piston to move. When the piston moves, the water in the water tank will be squeezed into the water pipe and then enter the water cavity. Then, the other water cavity is filled with water through the connecting pipe. Then, the water in the two water cavities is discharged through the nozzle and sprayed out in the state of high-pressure jet. At this time, the water flow is sprayed to the surface of the pipe, and rust removal can be completed. By pulling the pull rod by hand, the device can be moved on the pipe to remove the rust on the entire pipe surface.

[0015] Thirdly, in the present invention, by providing an air-drying component, after the rust is removed, the pull rod can be loosened, and the spring resets the pull rod and the conductive sheet thereon, thereby disconnecting the conductive sheet from the power supply. At this time, the telescopic motor is turned off, and the device no longer sprays water. Another pull rod is pulled, and the other pull rod will drive another conductive sheet to move, so that another power supply, the conductive rod and the conductive sheet form a loop. At this time, the fan is started, and the air flow flows from outside the device to the fan. The air flow passes through the groove and the air cavity, and then is ejected through the air jet hole. The water stains remaining on the surface of the pipe during the previous rust removal can be dried by the ejected air flow. By pulling the pull rod to move the device, all the water stains on the surface of the entire pipe can be dried. BRIEF DESCRIPTION OF THE DRAWINGS

A water spray assembly 5 is provided on the tool 2, and the water spray assembly 5 includes a second shell 51, the second shell 51 is fixedly connected to the second clamp 2, a water tank 52 and a telescopic motor 53 are fixedly connected inside the second shell 51, a piston 54 is slidably connected inside the water tank 52, the output shaft of the telescopic motor 53 is fixedly connected to the piston 54, a water pipe 55 is fixedly connected between the water tank 52 and the water chamber 42, a sealing plug 56 is provided on the second shell 51, a driving assembly 6 is provided inside the first shell 41 and the second shell 51, an auxiliary assembly 7 is provided on the first clamp 1 and the second clamp 2, a lock head and a lock nut are provided on the first clamp 1 and the second clamp 2, and when the first clamp 1 and the second clamp 2 are buckled together, they can be locked to fix the first clamp 1 and the second clamp 2 on the pipeline.

[0029] Furthermore, the driving assembly 6 includes a power supply 61 and a conductive rod 62. The two power supplies 61 and the two conductive rods 62 are respectively fixedly connected to the inside of the first shell 41 and the second shell 51. The two power supplies 61 and the two conductive rods 62 are respectively electrically connected to the telescopic motor 53 and the fan 47.

[0030] Furthermore, the driving assembly 6 also includes a pull rod 63 and a conductive sheet 64. The two pull rods 63 are respectively slidably connected to the first shell 41 and the second shell 51. The two conductive sheets 64 are respectively fixedly connected to the two pull rods 63. The conductive sheet 64 can move with the pull rods 63. When the conductive sheet 64 moves along the direction of the pull rods 63, it can contact the electrode of the power supply 61 and the conductive rod 62. At this time, the conductive rod 62, the conductive sheet 64 and the power supply 61 constitute a conductive circuit. The telescopic motor 53 and the fan 47 are the loads connected to the two circuits. Therefore, when the conductive sheet 64 moves, the telescopic motor 53 or the fan 47 will start.

[0031] Furthermore, the drive assembly 6 also includes a limit rod 65 and a spring 66. The two limit rods 65 are respectively fixedly connected to the two pull rods 63, one end of the two springs 66 is respectively fixedly connected to the inner walls of the first shell 41 and the second shell 51, and the other ends of the two springs 66 are respectively fixedly connected to the two limit rods 65.

[0032] Furthermore, the auxiliary component 7 includes a slide groove 71, a slide 72, a roller 73 and a compression spring 74, a plurality of slide grooves 71 are respectively opened on the first clamp 1 and the second clamp 2, a plurality of slides 72 are respectively slidably connected to the inside of the plurality of slide grooves 71, a plurality of rollers 73 are respectively rotationally connected to the plurality of slides 72, and a plurality of compression springs 74 are respectively fixedly connected between the inner walls of the plurality of slide grooves 71 and the plurality of slides 72.

[0033] Since there are rollers 73 in the first clamp 1 and the second clamp 2, when the device is installed on the pipe, the rollers 73 will be compressed, causing the slide 72 to move into the slide groove 71, so that the compression spring 74 will be squeezed. At this time, the elastic force of the compression spring 74 will be applied to the pipe through the roller 73, and the rolling friction between the roller 73 and the pipe will increase. At this time, when the pull rod 63 is pulled, the device will not move, but the pull rod 63 itself will move. When the limit rod 65 is against the inner wall of the first shell 41 or the second shell 51, if the pull rod 63 continues to be pulled, the entire device will move.

[0034] Furthermore, two connecting pipes 49 are provided between the first clamp 1 and the second clamp 2, wherein one connecting pipe 49 is connected between the two water chambers 42, and the other connecting pipe 49 is connected between the two air chambers 43. When the fan 47 inhales air, the airflow will enter the air chamber 43, and then enter the other air chamber 43 through the connecting pipe 49. The water in the water tank 52 will also enter the other water chamber 42 from one water chamber 42 through the connecting pipe 49.

[0035] Furthermore, the first clamp 1 and the second clamp 2 are symmetrically arranged, a plurality of nozzles 44 are located at one end of the first clamp 1 and the second clamp 2, and a plurality of jet holes 45 are located at the other end of the first clamp 1 and the second clamp 2. The plurality of nozzles 44 and the plurality of jet holes 45 are respectively located at both ends, which can avoid water splashing into the air cavity 43 during the rust removal process to the greatest extent.

[0036] The specific working method is: when it is necessary to remove rust from the outer wall of the pipeline, the first clamp 1 and the second clamp 2 can be moved to the pipeline, and the first clamp 1 and the second clamp 2 can be buckled together and locked to fix the device to the pipeline. During this process, multiple rollers 73 will press against the surface of the pipeline, and then the slide 72 will slide into the inside of the slide groove 71 to compress the compression spring 74, so that the multiple rollers 73 will press tightly against the surface of the pipeline. When removing rust, pull the pull rod 63 on the second shell 51 by hand. Since the roller 73 presses tightly against the surface of the pipeline, when the pull rod 63 is pulled, the pull rod 63 moves first, The limit rod 65 is driven to move until the limit rod 65 abuts against the inner wall of the second shell 51, and then the pull rod 63 is continued to be pulled, and the pull rod 63 will drive the second shell 51 and the entire device to move. At this time, the device can move on the surface of the pipeline. In the process of the pull rod 63 being pulled and the limit rod 65 abutting against the inner wall of the second shell 51, the conductive sheet 64 on the pull rod 63 will move between the electrode of the power supply 61 and the conductive rod 62. At this time, the power supply 61, the conductive rod 62, and the conductive sheet 64 are connected to form a complete circuit, and the telescopic motor 53 is the load connected in this circuit, so the telescopic motor 53 is started at this time, driving the piston 54 to move. When the piston 54 moves, the water in the water tank 52 is squeezed into the water pipe 55, and then enters the water chamber 42. Then, the other water chamber 42 is also filled with water through the connecting pipe 49. Then, the water in the two water chambers 42 is discharged through the nozzle 44 and sprayed out in the state of high-pressure jet. At this time, the water flow is sprayed onto the surface of the pipe to complete the rust removal. By pulling the pull rod 63 by hand, the device is moved on the pipe to remove the rust on the entire pipe surface. After the rust is removed, the pull rod 63 can be released, and the spring 66 resets the pull rod 63 and the conductive sheet 64 thereon, thereby Disconnect the conductive sheet 64 from the power supply 61. At this time, the telescopic motor 53 is turned off, and the device no longer sprays water. Pull another pull rod 63, and the other pull rod 63 will drive another conductive sheet 64 to move, so that another power supply 61, the conductive rod 62 and the conductive sheet 64 form a loop. At this time, the fan 47 is started, and the air flow flows from the outside of the device to the fan 47. The air flow passes through the groove 46 and the air cavity 43, and then is sprayed out through the air jet hole 45. The water stains remaining on the surface of the pipe during the previous rust removal can be dried by the sprayed air flow. Pull the pull rod 63 to move the device, and all the water stains on the surface of the entire pipe can be dried.
