Referring to fig. 1 to 6, the present invention provides a pipe cleaning machine.

In an embodiment of the present invention, the pipe cleaning machine includes:

an upper body 10 and a lower body 20;

the sprayer assembly 30 is arranged between the upper machine body 10 and the lower machine body 20;

the traveling mechanism 40 is mounted on the upper machine body 10 and/or the lower machine body 20, and is used for driving the upper machine body 10 and the lower machine body 20 to travel along a pipeline; and

The upper body 10 and the lower body 20 form a main body of the pipeline cleaning machine, and are mainly used for controlling the dragging cleaning pipe to move along the pipeline and spraying cleaning water to clean the inner wall of the pipeline.

In the present application, the traveling mechanism 40 may be separately installed on the upper body 10, or separately installed on the lower body 20, or partially installed on the upper body 10 and partially installed on the lower body 20.

Specifically, the driving member may be a motor, the traveling wheel 41 is in transmission connection with an output shaft of the motor, and a part of the traveling wheel 41 extends out of the lower body 20 and abuts against the inner wall of the pipeline, so that when the motor is started, the traveling wheel 41 is driven to rotate so as to advance along the inner wall of the pipeline. It can be understood that, after the upper body 10 and the lower body 20 are spread by the telescopic mechanism 50, the upper body 10 will also abut against the inner wall of the pipeline and move synchronously along with the travelling wheels 41, and the auxiliary wheels 42 are arranged to abut against the inner wall of the pipeline, so that the sliding friction between the upper body 10 and the inner wall of the pipeline is changed into rolling friction, thereby greatly reducing the friction resistance, making the moving process of the upper body 10 and the lower body 20 smoother, and facilitating the cleaning of the pipeline.

It should be noted that, in this embodiment, the number of the traveling wheels 41 may be four, two traveling wheels may be respectively disposed on two opposite sides of the lower body 20, the traveling wheels 41 are disposed at positions of the lower body 20 adjacent to the two ends, two auxiliary wheels 42 may be disposed, two auxiliary wheels 42 are respectively disposed on two opposite sides of the upper body 10, and two auxiliaries may be disposed at a middle position of the upper body 10, so that a connection line between the traveling wheels 41 and the auxiliary wheels 42 on each side of the upper body 10 and the lower body 20 may form a shape similar to a triangle, thereby, during traveling along a pipeline, force balance and stability can be ensured, and at the same time, additional traveling wheels 41 or auxiliary wheels 42 can be avoided, and cost can be saved. Of course, in other embodiments, the number of the auxiliary wheels 42 may be 4 corresponding to the traveling wheels 41, so that the balance and stability of the pipe cleaning machine during traveling are better.

Therefore, according to the pipe cleaning machine of the present invention, the traveling mechanism 40 is mounted on the upper body 10 and/or the lower body 20, so that the upper body 10, the lower body 20, and the head assembly 30 disposed between the upper body 10 and the lower body 20 can be driven to travel along the pipe, thereby performing liquid-jet cleaning on the pipe.

For example, when the telescopic mechanism 50 is composed of an air cylinder, the cylinder body of the air cylinder can be connected to the upper body 10, and one end of the piston rod is connected to the lower body 20, so that when the piston rod reciprocates relative to the cylinder body, the upper body 10 and the lower body 20 can be pushed or pulled to be away from or close to each other, and thus the distance between the upper body and the lower body is adjusted, and the traveling mechanism 40 is driven to abut against the inner wall of a pipeline, so as to adapt to cleaning of pipelines with different pipe diameters.

In an embodiment of the present application, an installation hole 511 is formed at one end of the fixing body 51, a first fixing column 11 is convexly disposed at one side of the upper body 10, and the first fixing column 11 is inserted into the installation hole 511, so that the fixing body 51 is detachably fixed to the first fixing column 11. The first fixing column 11 may be cylindrical, and the mounting hole 511 is correspondingly circular, and the first fixing column 11 and the mounting hole 511 may be fixed in an interference fit manner. Because the upper body 10 and the lower body 20 are used as carriers to carry other parts of the pipeline cleaning machine, and the weight is usually heavier, in the process of expanding the upper body 10 and the lower body 20 through the relative movement of the fixed body 51 and the movable body 52, the stress of the connection node between the upper body 10 and the fixed body 51 is also larger, in the embodiment, the connection node is fixed in a manner that the first fixing column 11 is matched with the mounting hole 511, so that the force borne by the connection node between the upper body 10 and the fixed body 51 can be uniformly distributed along the direction of the mounting hole 511 and the first fixing column 11360 °, thereby avoiding the stress from concentrating on a certain direction, causing the phenomenon of breaking and damage of the mounting hole 511 or the first fixing column 11, effectively increasing the connection strength of the connection node, and enabling the fixed body 51 and the upper body 10 to be stably and firmly connected.

Further, in the present application, a connection seat 70 is further disposed between the first fixing column 11 and the mounting hole 511, the connection seat 70 includes a seat head 71 and a seat body 72 that are connected to each other, the seat head 71 is connected to the first fixing column 11, and the seat body 72 is detachably inserted into the mounting hole 511. In this embodiment, the connecting seat 70 is substantially T-shaped, the seat head 71 and the seat body 72 are an integral structure, the structural strength is good, and the seat head 71 is easy to machine and form, the seat head 71 can be sleeved on the first fixing column 11, and the seat body 72 is inserted into the mounting hole 511, so that the connecting seat 70 can be conveniently and rapidly mounted and dismounted. Since the upper body 10 and the lower body 20 are used as supporting bodies to support other parts of the pipeline cleaning machine, and the weight is generally heavier, in the process of expanding the upper body 10 and the lower body 20 through the relative movement of the fixed body 51 and the movable body 52, the stress of the connection node between the upper body 10 and the fixed body 51 is also larger, so that in the process of repeated telescopic movement of the upper body 10 and the lower body 20, the connection part of the mounting hole 511 and the first fixing column 11 is easily worn, and the fixed body 51 and the first fixing column 11 arranged on the upper body 10 are difficult to repair, and the maintenance cost is high. In this implementation, locate between mounting hole 511 and first fixed column 11 through connecting seat 70 detachably, make connecting seat 70 carry out the transitional coupling to after connecting seat 70 appears wearing and tearing, also can conveniently change fast, and connecting seat 70 cost is lower, greatly reduced the cost of maintaining.

In an embodiment of the present application, one end of the movable body 52 has a connection hole 521, a second fixing column 21 is convexly disposed on one side of the lower body 20, and the second fixing column 21 is inserted into the connection hole 521, so that the movable body 52 is detachably fixed to the second fixing column 21. It is understood that the connecting hole 521 may also be a circular hole, and the second fixing post 21 is a matching cylinder, and the connecting hole 521 and the second fixing post 21 may be fixed by interference fit. Because the upper body 10 and the lower body 20 are used as supporting bodies to support other components of the pipeline cleaning machine, and the weight is usually heavier, in the process of expanding the upper body 10 and the lower body 20 through the relative movement of the fixed body 51 and the movable body 52, the stress on the connection node between the lower body 20 and the movable body 52 is also larger, in the embodiment, the connection node is fixed in a manner that the second fixing column 21 is matched with the connection hole 521, so that the force borne by the connection node between the lower body 20 and the movable body 52 can be uniformly distributed along the 360-degree directions of the connection hole 521 and the second fixing column 21, the stress is prevented from being concentrated in a certain direction, the connection hole 521 or the second fixing column 21 is prevented from being broken or damaged, the connection strength of the connection node is effectively increased, and the movable body 52 and the lower body 20 are stably and firmly connected.
