[0031] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0032] like Figure 1 、 2 As shown in Figures 3, 4, 5, 6, and 7, a pipe cleaning drive platform includes a mounting frame 1 and at least one cleaning drive device, wherein the cleaning drive device includes:

[0033] The cleaning mechanism comprises a connecting shaft 2 and a cleaning brush connected to the connecting shaft 2;

[0034] A gear set comprising a rotating member 31 rotatably mounted on the mounting frame 1 , a plurality of small gears 32 evenly distributed along the circumference of the rotating member 31 and rotatably mounted on the rotating member 31 , and a large gear 33 configured to mesh with each small gear 32 and be fixed to the mounting frame 1 ;

[0035] a rotation drive mechanism 4 connected to the rotating member 31 and configured to drive the rotating member 31 to rotate;

[0036] A plurality of axially shifted driving wheels 5 are provided, and each axially shifted driving wheel 5 clamps the connecting shaft 2 together. Each axially shifted driving wheel 5 is connected to a pinion 32 via an angle mechanism 6. The angle mechanism 6 is installed on the rotating member 31 for transmitting torque.

[0037] During the operation of the cleaning drive device, the rotating drive mechanism 4 drives the rotating part 31 to rotate. During the rotation, the rotating part 31 drives the small gear 32, the angle mechanism 6 and the axial shift driving wheel 5 to revolve. Several axial shift driving wheels 5 clamp the connecting shaft 2, thereby driving the connecting shaft 2 and the cleaning brush to rotate. The small gear 32 rotates in the process of revolving around the large gear, and then drives the axial shift driving wheel 5 to rotate through the angle mechanism 6. The connecting shaft 2 moves axially under the action of several axial shift driving wheels 5. The connecting shaft 2 drives the cleaning brush to rotate and move axially along the pipe. The connecting shaft 2 can drive the cleaning brush to enter from one port of the pipe, extend from the other port, and then retract, thereby completing the cleaning of the inner wall of the pipe.

[0038] Specifically, this embodiment can simultaneously drive the cleaning brush to rotate and move along the axial direction of the pipe, thereby being able to clean the inner wall of the pipe well, with good cleaning effect and high cleaning efficiency; this embodiment only uses a rotary drive mechanism 4 as a power source, and completes the rotation and axial drive of the cleaning brush through the cooperation of the gear set, the axial drive wheel 5 and the corner mechanism 6, thereby greatly reducing the volume and floor space of the pipe cleaning drive platform, and also saving costs; this embodiment is also suitable for pipes of various lengths.

[0039] In this embodiment, the rotary drive mechanism 4 includes a motor, and the rotating member 31 can be a planetary disk with a circle of external teeth on its periphery. The output shaft of the motor is connected to the planetary disk through a transmission gear or a transmission belt.

[0040] In this embodiment, the angle turning mechanism 6 is a reduction gear box, which is fixedly mounted on the rotating member 31. The angle turning mechanism 6 can also be a worm gear pair, a bevel gear pair, etc.

[0041] In this embodiment, the connecting shaft 2 is a flexible shaft, and the material can be selected from fiberglass reinforced plastics. Using a flexible shaft as the connecting shaft 2 can, on the one hand, avoid being too hard, thereby preventing damage during the pipe cleaning process, and on the other hand, it can allow the cleaning brush to swing within a certain range during rotation, thereby improving the cleaning effect and being applicable to pipes of various inner diameter specifications.

[0042] In this embodiment, the pipe can be a stainless steel pipe, etc. There are four pinions 32, and the axial shift driving wheel 5 has an annular groove on its circumference. The bottom of the annular groove is arc-shaped, and the annular grooves of the four axial shift driving wheels 5 clamp the pipe together.

[0043] In this embodiment, three cleaning drive devices are arranged in parallel, and three pipes can be cleaned at the same time.

[0044] like Figure 3 、 4As shown in Figures 5 and 7, the large gear 33 is rotatably mounted on the fixed axis of the mounting frame 1, and the rotation center line coincides with the rotation center line of the rotating member 31. The mounting frame 1 is equipped with a brake mechanism 7, which is used to lock the large gear 33 during braking so that the large gear 33 cannot rotate relative to the mounting frame 1.

[0045] Such a configuration allows the large gear 33 to be both fixed on the mounting frame 1 and to rotate. After the brake mechanism 7 releases the lock on the large gear 33, the small gear 32 and the large gear 33 rotate with the rotating member 31 around the rotation center line of the rotating member 31 at the same angular velocity, and the small gear 32 does not rotate on its own, thereby causing the axial shift drive wheel 5 to only revolve with the rotating member 31 and not rotate on its own, thereby allowing the connecting shaft 2 to only rotate without axial shift. Each time the cleaning brush is extended from the pipe, the brake mechanism 7 releases the lock on the large gear, causing the entire pipe cleaning drive platform to only drive the connecting shaft 2 to rotate. Alternatively, it can only drive the connecting shaft 2 to rotate at specific time intervals, thereby shaking off or cleaning the oil stains on the cleaning brush. In this embodiment, the oil stains on the cleaning brush are cleaned each time the cleaning brush is extended from the pipe, thereby preventing the oil stains on the cleaning brush from sticking to the inner wall of the pipe during the process of the cleaning brush being retracted.

[0046] In this embodiment, the pipe cleaning drive platform further includes a brush cleaning unit, which is configured to act on the cleaning brush to clean it when the brake mechanism 7 releases the lock on the large gear 33 and the cleaning brush rotates. The brush cleaning unit can be a cleaning brush that removes oil stains from the cleaning brush during its rotation.

[0047] The working method of the pipe cleaning drive platform in this embodiment includes:

[0048] S1, the brake mechanism 7 brakes, and the rotary drive mechanism 4 drives the rotating member 31 to rotate, so that the connecting shaft drives the cleaning brush to enter the pipe during the rotation process and move along the axial direction of the pipe, thereby cleaning the inside of the pipe;

[0049] S2, after the cleaning brush extends out of the pipe, the brake mechanism 7 is released, so that the connecting shaft only drives the cleaning brush to rotate. During the rotation of the cleaning brush, the cleaning brush cleaning part clears the oil stains on the cleaning brush;

[0050] S3, the brake mechanism brakes, and the rotary drive mechanism 4 drives the rotating member 31 to reverse, so that the connecting shaft 2 drives the cleaning brush to exit the pipe.

[0051] like Figure 3 、 4 As shown in , 5, and 7, the brake mechanism 7 includes:

[0052] The brake fitting portion 71 is fixedly mounted on the large gear 33 and sleeved outside the fixed shaft;

[0053] The clamping mechanism 72 is mounted on the mounting frame 1 and is used to clamp the brake fitting portion 71 to fix the large gear 33 on the mounting frame 1 or to loosen the large gear 33 to allow the large gear 33 to rotate.

[0054] In this embodiment, the brake mechanism 7 may also be a locking mechanism or the like.

[0055] like Figure 3 、 4 As shown in Figures 5 and 7, the clamping mechanism 72 includes a brake power member 722 and two half clamps 721 that together form an embracing cavity for clamping the brake fitting part 71, wherein one of the half clamps 721 is fixedly mounted on the mounting frame 1, and the first ends of the two half clamps 721 are hinged to each other, and the brake power member 722 is assembled between the second ends of the two half clamps 721 to drive the second ends of the two half clamps 721 to move toward or away from each other.

[0056] In this embodiment, the brake power member 722 can be an air cylinder, an oil cylinder, etc., and the clamping mechanism 72 can also be an existing clamp or clamping mechanism, etc.

[0057] like Figure 1 、 3 As shown in Figures 4 and 5, the cleaning drive device further includes a water inlet pipe 8, which is covered outside the connecting shaft 2 and is used for the pipe to be cleaned to connect with the water inlet pipe.

[0058] In this embodiment, a water inlet is provided on the wall of the water inlet pipe 8. When the cleaning brush cleans the inner wall of the pipe, water flows into the pipe through the water inlet pipe 8, thereby better cleaning the pipe.

[0059] like Figure 1 、 3 As shown in FIG4 , the port of the water inlet pipe 8 for connecting with the pipe is a bell mouth 81. This arrangement facilitates the connection between the pipe and the water inlet pipe 8.

[0060] like Figure 3 As shown, a sealing sleeve 82 is disposed at the bottom of the bell mouth 81. The sealing sleeve 82 has an abutting surface for abutting against the end face of the pipe. This arrangement can prevent water from leaking from the pipe inlet.

[0061] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
