Description

Technical Field

[0001] This utility model relates to the field of rubber tube cleaning, specifically to a cleaning airflow blowing device for the inside of a rubber tube. Background Technology

[0002] Automotive pipeline purging devices use compressed air or other clean gases to purge the internal pipelines of a vehicle, removing accumulated dust, coke, and other impurities to ensure the unobstructed flow and normal operation of the pipeline system.

[0003] The working principle of an automotive pipeline purging device is relatively simple. It introduces compressed air or other clean gas into the pipeline system, utilizing the impact force and carrying capacity of the airflow to remove impurities and dirt from the pipeline. Simultaneously, the purging device can adjust the pressure and flow rate of the purging gas according to the specific structure and needs of the pipeline system to achieve optimal cleaning results. This type of device typically requires manual operation, i.e., manually controlling the pressure and flow rate of the gas at the outlet for purging. It is suitable for some relatively simple pipeline systems. Automatic purging devices also exist; however, this method automatically controls the gas pressure and flow rate, as well as the purging time and cycle, through preset programs and sensors. It is suitable for some complex pipeline systems. Furthermore, to fully utilize automotive space, the pipeline structure design is more compact, with relatively fewer bends.

[0004] Therefore, automotive piping systems not only consist of straight pipes but also include bends. Existing piping cleaning devices, whether manual or automatic, can only clean near the inlet of bends and cannot penetrate into the bends themselves. This results in ineffective cleaning of the interior of the piping.

[0005] Therefore, it is very necessary to provide a cleaning airflow purging device for the inside of a rubber tube to solve the above-mentioned technical problems. Utility Model Content

[0006] Based on the above description, this utility model provides a cleaning airflow blowing device for the inside of a rubber tube to solve the problem of poor cleaning effect inside the bend of the prior art.

[0008] Furthermore, the spray gun includes a nozzle, a first air supply pipe and a second air supply pipe. The nozzle is radially provided with a plurality of air holes. One end of the first air supply pipe is connected to the nozzle. One end of the second air supply pipe is connected to the first air supply pipe, and the other end of the second air supply pipe is connected to an air pump.

[0009] Furthermore, the driven vehicle is provided with a driven main vehicle and a driven auxiliary vehicle, the driven main vehicle being connected to the nozzle; at least one driven auxiliary vehicle is provided, the driven auxiliary vehicle being connected to the first air supply pipe.

[0010] Furthermore, the first gas supply pipe is made of metal flexible tubing, and the second gas supply pipe is made of PA nylon flexible tubing.

[0011] Furthermore, the driven vehicle includes a pipe support, a first support wheel, and a second support wheel. The pipe support is sleeved on the spray gun component. The first support wheel is provided in a pair, and the pair of first support wheels are symmetrically connected to the lower end of the pipe support, with the first support wheel located on the side closer to the tractor. The second support wheel is connected to the upper end of the pipe support, and the second support wheel abuts against the pipe.

[0012] Furthermore, the pipe support has support cylinders on both sides of its upper end. The second support wheel includes a telescopic rod, a telescopic spring, and a driven second wheel. There is a pair of telescopic rods, and the telescopic rods are slidably connected to the two support cylinders. One end of the telescopic spring is connected to the support cylinder, and the other end of the telescopic spring is connected to the telescopic rod. The driven second wheel is connected to the end of the telescopic rod away from the support cylinder.

[0013] Furthermore, the telescopic rod has a telescopic rod groove at one end near the driven second wheel, and also includes a rotating joint. The rotating joint includes a rotating seat, which is rotatably connected to the telescopic rod, and the rotating seat has a rotating seat groove.

[0014] Furthermore, it also includes a limiting component, which includes a limiting rod and a limiting spring. The limiting rod is slidably connected to the groove of the rotating seat and can abut against the groove of the telescopic rod. One end of the limiting spring is connected to the groove of the rotating seat, and the other end of the limiting spring is connected to the limiting rod.

[0015] Furthermore, the tractor includes a traction support seat, a first drive wheel, and a second drive wheel. The first drive wheel is provided in a pair, and the pair of first drive wheels is symmetrically connected to the front end of the traction support seat. The second drive wheel is provided in a pair, and the pair of second drive wheels is symmetrically connected to the rear end of the traction support seat.

[0016] Furthermore, the first driving wheel includes a connecting rod, a wheel frame, a driving roller, a driving gear, a drive motor, and a motor gear. The connecting rod is fixedly connected to the traction support seat; the upper end of the wheel frame is rotatably connected to the connecting rod; the driving roller is rotatably connected to the lower end of the wheel frame; the driving gear is connected to the driving roller; the drive motor has a fixed end and a rotating end, the fixed end of the drive motor is connected to the wheel frame; the motor gear is connected to the rotating end of the drive motor, and the motor gear meshes with the driving gear.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] The tractor moves on the outside of the pipe, while the driven vehicle moves on the inside. Thus, the tractor can move the driven vehicle. The spray gun is connected to the driven vehicle, and as the driven vehicle moves from one end of the pipe to the other, the spray gun thoroughly cleans the inside of the pipe. This solves the problem that existing pipe cleaning devices, whether manual or automatic, can only clean near the inlet of bends and cannot enter the inside of the bends. This results in poor cleaning effectiveness inside the pipe. Attached Figure Description

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0041] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0042] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0043] like Figures 1 to 7 As shown, a cleaning airflow purging device for the inside of a rubber hose includes a driven vehicle 1, an iron block 11, a traction vehicle 2, and a spray gun 3. The driven vehicle 1 is located inside the pipe; the iron block 11 is mounted on the driven vehicle 1; the traction vehicle 2 is located outside the pipe and is correspondingly arranged with the driven vehicle 1; a magnet 21 is mounted on the traction vehicle 2 and is correspondingly arranged with the iron block 11; the traction vehicle 2 can drive the driven vehicle 1 to move; and the spray gun 3 is connected to the driven vehicle 1 and can purge the pipe.

[0044] In some embodiments, the tractor 2 moves outside the pipe, and the driven vehicle 1 moves inside the pipe. Thus, the tractor 2 can drive the driven vehicle 1 to move. The spray gun 3 is connected to the driven vehicle 1, and as the driven vehicle 1 moves from one end of the pipe to the other, the spray gun 3 thoroughly cleans the inside of the pipe. This solves the problem that existing pipe cleaning devices, whether manual or automatic, can only clean near the inlet of bends and cannot enter the inside of bends. This results in poor cleaning effectiveness inside the pipe.

[0045] In some embodiments, the spray gun 3 includes a nozzle 31, a first air supply pipe 32 and a second air supply pipe 33. The nozzle 31 is provided with a plurality of air holes 311 in the radial direction. One end of the first air supply pipe 32 is connected to the nozzle 31. One end of the second air supply pipe 33 is connected to the first air supply pipe 32, and the other end of the second air supply pipe 33 is connected to an air pump 34.

[0046] In some embodiments, the driven vehicle 1 is provided with a driven main vehicle 12 and a driven auxiliary vehicle 13, the driven main vehicle 12 being connected to the nozzle 31; at least one driven auxiliary vehicle 13 is provided, and the driven auxiliary vehicle 13 is connected to the first air supply pipe 32.

[0047] In some embodiments, the first gas supply pipe 32 is a metal hose, and the second gas supply pipe 33 is a PA nylon hose.

[0048] In this embodiment, the first air supply pipe 32 is a metal flexible hose, which reduces wear on the first air supply pipe 32 during the movement of the driven car 1. The second air supply pipe 33 is a PA nylon flexible hose, which will not cause excessive interference to the movement of the driven car 1 under the drive of the driven car 1. In addition, the only difference between the driven main car 12 and the driven auxiliary car 13 of the driven car 1 is that the driven main car 12 is equipped with an iron block 11, while the driven auxiliary car 13 is not equipped with an iron block 11.

[0049] In some embodiments, the driven vehicle 1 includes a pipe support 14, a first support wheel 15, and a second support wheel 16. The pipe support 14 is sleeved on the spray gun 3. A pair of first support wheels 15 are provided, and the pair of first support wheels 15 are symmetrically connected to the lower end of the pipe support 14, and the first support wheels 15 are located on the side closer to the tractor 2. The second support wheel 16 is connected to the upper end of the pipe support 14, and the second support wheel 16 abuts against the pipe.

[0050] In this embodiment, the first support wheel 15 is disposed at the lower end of the pipe support 14 and abuts against the lower end of the pipe. The second support wheel 16 is disposed at the upper end of the pipe support 14 and abuts against the middle of the pipe. Driven by the tractor 2, the first support wheel 15 and the second support wheel 16 are tightly abutted against the inside of the pipe and can smoothly pass through the bends of the pipe. In addition, the positions of the driven vehicle 1 and the tractor 2 on the pipe can be one of the following: upper, lower, left, or right.

[0051] In some embodiments, the pipe support 14 has support cylinders 141 on both sides of its upper end. The second support wheel 16 includes a telescopic rod 161, a telescopic spring 162, and a driven second wheel 163. The telescopic rods 161 are provided in pairs and are slidably connected to the two support cylinders 141. One end of the telescopic spring 162 is connected to the support cylinder 141, and the other end of the telescopic spring 162 is connected to the telescopic rod 161. The driven second wheel 163 is connected to the end of the telescopic rod 161 away from the support cylinder 141.

[0052] In this embodiment, when the pipe diameter is large, the telescopic spring 162 pushes the telescopic rod 161 to extend, so as to better contact the pipe.

[0053] In some embodiments, the telescopic rod 161 has a telescopic rod groove 1611 at one end near the driven second wheel 163, and also includes a rotary joint 17, which includes a rotating seat 171. The rotating seat 171 is rotatably connected to the telescopic rod 161, and the rotating seat 171 has a rotating seat groove 1711.

[0054] In some embodiments, a limiting member 172 is further included, the limiting member 172 including a limiting rod 1721 and a limiting spring 1722, the limiting rod 1721 being slidably connected to the rotating seat groove 1711, and the limiting rod 1721 being able to abut against the telescopic rod groove 1611; one end of the limiting spring 1722 is connected to the rotating seat groove 1711, and the other end of the limiting spring 1722 is connected to the limiting rod 1721.

[0055] In this embodiment, when the pipe diameter is large, rotating the rotary joint 17 rotates the driven second wheel 163 of the driven vehicle 1 to a downward position to facilitate better contact with the pipe. Furthermore, when the rotary joint 17 rotates to the appropriate position, the limiting spring 1722 included in the limiting member 172 pushes out the limiting rod 1721, which then abuts against the groove 1611 of the telescopic rod. Thus, it can be determined that the rotary joint 17 has rotated to the correct position.

[0056] In some embodiments, the tractor 2 includes a traction support 22, a first drive wheel 23 and a second drive wheel 24. The first drive wheel 23 is provided in a pair, and the pair of first drive wheels 23 are symmetrically connected to the front end of the traction support 22. The second drive wheel 24 is provided in a pair, and the pair of second drive wheels 24 are symmetrically connected to the rear end of the traction support 22.

[0057] In some embodiments, the first drive wheel 23 includes a connecting rod 231, a wheel frame 232, a drive roller 233, a drive gear 234, a drive motor 235, and a motor gear 236. The connecting rod 231 is fixedly connected to the traction support seat 22. The upper end of the wheel frame 232 is rotatably connected to the connecting rod 231. The drive roller 233 is rotatably connected to the lower end of the wheel frame 232. The drive gear 234 is connected to the drive roller 233. The drive motor 235 has a fixed end and a rotating end. The fixed end of the drive motor 235 is connected to the wheel frame 232. The motor gear 236 is connected to the rotating end of the drive motor 235, and the motor gear 236 meshes with the drive gear 234.

[0058] In this embodiment, the first drive wheel 23 is symmetrically connected to the front end of the traction support 22; a pair of second drive wheels 24 are provided, and the pair of second drive wheels 24 are symmetrically connected to the rear end of the traction support 22. The drive motor 235 drives the motor gear 236 to rotate, the motor gear 236 drives the drive gear 234 to rotate, and the drive gear 234 drives the drive roller 233 to rotate. Thus, the tractor 2 is driven. In addition, the drive motor 235 is a Siemens 1FL6042-2AF21-1AA1 motor.

[0059] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0060] The tractor moves on the outside of the pipe, while the driven vehicle moves on the inside. Thus, the tractor can move the driven vehicle. The spray gun is connected to the driven vehicle, and as the driven vehicle moves from one end of the pipe to the other, the spray gun thoroughly cleans the inside of the pipe. This solves the problem that existing pipe cleaning devices, whether manual or automatic, can only clean near the inlet of bends and cannot enter the inside of the bends. This results in poor cleaning effectiveness inside the pipe.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
