Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe processing, and specifically relates to an internal cleaning mechanism for metal pipes. Background Technique

[0002] When metal pipes are used to transport liquids or gases, dirt and deposits on their inner walls will increase the flow resistance of the fluid. Therefore, it is necessary to clean the inner walls of metal pipes to improve the fluid transmission efficiency. In actual production, in order to control the flow rate of the fluid, metal pipes of different thicknesses are produced, and most cleaning mechanisms do not have a variable diameter function, resulting in the inability to clean pipes of different thicknesses, thus limiting the cleaning range.

[0003] Therefore, in order to solve the defect that the pipe cleaning mechanism does not have a variable diameter function, it is very necessary to propose an internal cleaning mechanism for metal pipes. Content of the Utility Model

[0004] The purpose of the utility model is to provide an internal cleaning mechanism for metal pipes. By moving the slider to drive the cleaning brush to move left and right until the cleaning brush fits the inner wall of the pipe, the function of variable diameter can be realized, which is suitable for cleaning pipes of different thicknesses, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An internal cleaning mechanism for metal pipes, including a machine body, a cleaning tank arranged at the lower end of the machine body, and a lifting plate arranged at the upper end of the cleaning tank. The lower end of the lifting plate is movably installed with a cleaning component through a driving shaft. The cleaning component includes a rotating plate fixedly connected to the driving shaft. A slider is slidably arranged in the rotating plate, and a cleaning brush is fixedly installed at the lower end of the slider;

[0007] A plurality of adjustment holes are opened on the rotating plate, and the slider is fixedly connected to the adapted adjustment hole through a bolt.

[0008] Preferably, a rotating shaft is movably installed on the lifting plate, a first bevel gear is fixedly connected to the rotating shaft, and a second bevel gear meshing with the first bevel gear is installed at the top end of the driving shaft.

[0009] Preferably, the cleaning tank is filled with cleaning liquid, and a water changing port is opened at the front end.

[0010] Preferably, clamping plates are symmetrically arranged before and after in the cleaning tank, and the clamping plates are fixedly connected to hydraulic cylinders.

[0011] Preferably, an arc-shaped groove fitting the outer wall of the metal pipe is opened at the clamping end of the clamping plate, and both ends of the clamping plate are slidably connected to the inner wall of the cleaning tank.

[0012] Preferably, a threaded rod is movably installed on the machine body. The lifting plate is threadedly connected to the threaded rod, and both ends thereof are slidably connected to the machine body.

[0013] Preferably, motors are fixedly connected to one ends of the rotating shaft and the threaded rod respectively.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In this internal cleaning mechanism for metal pipes, the cleaning brush is driven to move left and right by moving the slider until the cleaning brush fits against the inner wall of the pipe, realizing the function of variable diameter, being applicable to cleaning pipes of different thicknesses, greatly expanding the applicable range of the cleaning mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] To solve the technical problem of how to immerse the pipe in the cleaning liquid, please refer to Figure 1 - Figure 2 , the following technical solutions are provided in this embodiment:

[0023] A metal pipe internal cleaning mechanism, including a machine body 1 and a cleaning tank 2 provided at the lower end of the machine body 1. The cleaning tank 2 is filled with a cleaning liquid, and a water changing port 21 is opened at the front end. Clamping plates 22 are symmetrically arranged in the front and rear in the cleaning tank 2. The clamping plates 22 are fixedly connected with hydraulic cylinders 23. An arc-shaped groove 221 that fits the outer wall of the metal pipe is opened at the clamping end of the clamping plates 22. Both ends of the clamping plates 22 are slidably connected to the inner wall of the cleaning tank 2.

[0024] Among them, the depth of the cleaning tank 2 is greater than the length of the pipe. A valve body is installed at the water changing port 21. When the cleaning liquid needs to be replaced, the valve body is opened, and an external device is used to pump out the dirty cleaning liquid inside the cleaning tank 2.

[0025] Specifically, an appropriate amount of cleaning liquid is loaded into the cleaning tank 2 (the cleaning liquid can overflow the top of the pipe after the pipe is placed). The pipe is placed into the cleaning tank 2 manually. Then, two hydraulic cylinders 23 are started, so that the hydraulic cylinders 23 drive the clamping plates 22 to move towards the pipe until the arc-shaped groove 221 fits the outer wall of the pipe, realizing the clamping of the metal pipe, and making the whole pipe immersed in the cleaning liquid.

[0026] To solve the technical problem of how the cleaning brush cleans the inner wall of the pipe, please refer to Figure 3 This embodiment provides the following technical solutions:

[0027] A lifting plate 3 is provided at the upper end of the cleaning tank 2. A threaded rod 11 is movably installed on the machine body 1. The lifting plate 3 is threadedly connected to the threaded rod 11, and both ends of it are slidably connected to the machine body 1.

[0028] A cleaning component 35 is movably installed at the lower end of the lifting plate 3 through a driving shaft 34. A rotating shaft 31 is movably installed on the lifting plate 3. A first bevel gear 32 is fixedly connected to the rotating shaft 31. A second bevel gear 33 meshing with the first bevel gear 32 is installed at the top end of the driving shaft 34.

[0029] Among them, motors are fixedly connected to one ends of both the threaded rod 11 and the rotating shaft 31.

[0030] Specifically, start the motor to drive the threaded rod 11 to rotate. Since the lifting plate 3 is threadedly connected to the threaded rod 11 and both ends of the lifting plate 3 are slidably connected to the machine body 1, the lifting plate 3 can move down stably until the cleaning component 35 is inserted into the pipe. Then, start the motor to drive the rotating shaft 31 to rotate. The rotating shaft 31 drives the first bevel gear 32 fixedly connected to it to rotate. The first bevel gear 32 then drives the second bevel gear 33 meshing with it to rotate. The second bevel gear 33 then drives the cleaning component 35 to rotate through the driving shaft 34, realizing the cleaning of the inner wall of the pipe.

[0031] To solve the technical problem of how the cleaning mechanism realizes the variable diameter function, please refer to Figure 4 This embodiment provides the following technical solutions:

[0032] The cleaning assembly 35 includes a rotating plate 351 fixedly connected to the drive shaft 34. A slider 353 is slidably disposed within the rotating plate 351. A cleaning brush 354 is fixedly installed at the lower end of the slider 353. A plurality of adjustment holes 352 are formed in the rotating plate 351, and the slider 353 is fixedly connected to the adapted adjustment hole 352 by a bolt.

[0033] Specifically, when cleaning pipes of different sizes, first remove the bolt, then move the slider 353 within the rotating plate 351. The slider 353 drives the cleaning brush 354 to move left and right until the cleaning brush 354 fits against the inner wall of the pipe. Then, use the bolt to fixedly connect the slider 353 to the corresponding adjustment hole 352 to achieve the variable diameter function, so as to be applicable to cleaning pipes of different thicknesses.

[0034] Working principle: For this internal cleaning mechanism of metal pipes, during use, first load an appropriate amount of cleaning liquid into the cleaning tank 2, then manually place the pipe into the cleaning tank 2, start the hydraulic cylinder 23 to drive the clamping plate 22 to move until the clamping plate 22 clamps the pipe, then start the motor to drive the threaded rod 11 to rotate, so that the lifting plate 3 moves downward until the cleaning brush 354 is inserted into the pipe. Remove the bolt and move the slider 353 until the cleaning brush 354 fits against the inner wall of the pipe, then fix the slider 353 with the bolt. Then start the motor to drive the rotating shaft 31 to rotate. The rotating shaft 31 drives the drive shaft 34 to rotate through the meshing of the first bevel gear 32 and the second bevel gear 33, and the drive shaft 34 drives the cleaning brush 354 to rotate along the inner wall of the pipe through the rotating plate 351, realizing the cleaning of the inner wall of the pipe.
