[0036] Combined with reference Figures 1 to 6 , the present invention provides a pipeline cleaning machine.

[0037] In an embodiment of the present invention, the pipeline cleaning machine comprises:

[0038] An upper fuselage 10 and a lower fuselage 20;

[0039] A nozzle assembly 30, wherein the nozzle assembly 30 is disposed between the upper body 10 and the lower body 20;

[0040] a walking mechanism 40, wherein the walking mechanism 40 is installed on the upper body 10 and / or the lower body 20 and is used to drive the upper body 10 and the lower body 20 to move along the pipeline; and

[0041] The telescopic mechanism 50 has one end connected to the lower body 20 and the other end connected to the upper body 10. When the telescopic mechanism 50 is actuated, it drives the upper body 10 to move relative to the lower body 20 to adjust the distance between the upper body 10 and the lower body 20.

[0042] The upper body 10 and the lower body 20 constitute the main body of the pipeline cleaning machine, which are mainly used to control the dragging of the cleaning pipe along the pipeline and spray cleaning water to clean the inner wall of the pipeline.

[0043] In the present application, the walking mechanism 40 can be installed on the upper body 10 alone, or installed on the lower body 20 alone, or partially installed on the upper body 10 and partially installed on the lower body 20. In one embodiment, the walking mechanism 40 includes a driving member (not shown), a walking wheel 41 and an auxiliary wheel 42, the driving member is installed on the lower body 20, the walking wheel 41 is installed on the lower body 20 and is in transmission connection with the driving member, and the auxiliary wheel 42 is installed on the upper body 10. Specifically, the driving member can be a motor, the walking wheel 41 is in transmission connection with the output shaft of the motor, and the walking wheel 41 partially extends out of the lower body 20 and abuts against the inner wall of the pipe, so when the motor is started, the driving wheel 41 rotates to move along the inner wall of the pipe. It can be understood that after the upper body 10 and the lower body 20 are stretched apart by the telescopic mechanism 50, the upper body 10 will also abut against the inner wall of the pipe and move synchronously with the running wheels 41. By providing the auxiliary wheels 42, the auxiliary wheels 42 are made to abut against the inner wall of the pipe, so that the sliding friction between the upper body 10 and the inner wall of the pipe is converted into rolling friction, thereby greatly reducing the friction resistance, making the movement of the upper body 10 and the lower body 20 smoother, thereby facilitating the cleaning of the pipe.

[0044] It should be noted that in this embodiment, the number of running wheels 41 can be four, and two are respectively arranged on the opposite sides of the lower fuselage 20, and the running wheels 41 are arranged at the positions near the two ends of the lower fuselage 20, while two auxiliary wheels 42 can be arranged, and the two auxiliary wheels 42 are respectively arranged on the opposite sides of the upper fuselage 10, and the two auxiliary wheels can be arranged in the middle position of the upper fuselage 10, so that the connecting line between the running wheels 41 and the auxiliary wheels 42 on each side of the upper fuselage 10 and the lower fuselage 20 can form a similar triangle shape, thereby, in the process of moving along the pipeline, the balance and stability of the force can be guaranteed, and at the same time, the addition of additional running wheels 41 or auxiliary wheels 42 can be avoided, saving costs. Of course, in other embodiments, four auxiliary wheels 42 can also be arranged corresponding to the running wheels 41, thereby making the balance and stability of the pipeline cleaning machine better during the moving process.

[0045] Therefore, the pipeline cleaning machine of the technical solution of the present invention can drive the upper body 10, the lower body 20 and the nozzle assembly 30 arranged between the upper body 10 and the lower body 20 to move along the pipeline, thereby spraying and cleaning the pipeline. By connecting one end of the telescopic mechanism 50 to the upper body 10 and the other end to the lower body 20, when the telescopic mechanism 50 is in motion, the upper and lower bodies 20 are driven to move relative to each other to expand or reduce the distance between the upper body 10 and the lower body 20, and at the same time, the walking mechanism 40 and the inner wall of the pipeline are moved closer to or away from each other. Therefore, even when cleaning pipelines of different diameters, the distance between the bodies can be adjusted by adjusting the telescopic mechanism 50, so that the walking mechanism 40 and the inner wall of the pipeline are in contact and matched, which greatly improves the versatility of the pipeline cleaning machine and caters to the needs of the market.

[0046] In an embodiment of the present application, the telescopic mechanism 50 includes a fixed body 51 and a movable body 52 movably connected to the fixed body 51, wherein one end of the fixed body 51 away from the movable body 52 is connected to one of the upper fuselage 10 and the lower fuselage 20, and one end of the movable body 52 away from the fixed body 51 is connected to the other of the upper fuselage 10 and the lower fuselage 20.

[0047] For details, please refer to Figure 2 , Figure 5The telescopic mechanism 50 may be formed by a linear motor, and the fixed body 51 and the movable body 52 are formed as the primary and secondary structures of the linear motor accordingly. Alternatively, the telescopic mechanism 50 may also be formed by a driving cylinder or a hydraulic cylinder, and the fixed body 51 and the movable body 52 are formed as a cylinder body and a piston rod structure. For example, when the telescopic mechanism 50 is formed by a cylinder, the cylinder body of the cylinder may be connected to the upper body 10, and one end of the piston rod may be connected to the lower body 20. In this way, when the piston rod reciprocates relative to the cylinder body, the upper body 10 and the lower body 20 may be pushed or pulled away from or closer to each other, thereby adjusting the distance between the two, and then driving the walking mechanism 40 to abut against the inner wall of the pipeline, so as to adapt to the cleaning of pipelines with different diameters.

[0048] In one embodiment of the present application, a mounting hole 511 is provided at one end of the fixed body 51, and a first fixing column 11 is convexly provided on one side of the upper body 10, and the first fixing column 11 is inserted into the mounting hole 511, so that the fixed body 51 can be detachably fixed to the first fixing column 11. Among them, the first fixing column 11 can be cylindrical, and the mounting hole 511 is correspondingly circular, and the first fixing column 11 and the mounting hole 511 can be fixed by interference fit. Since the upper fuselage 10 and the lower fuselage 20 are used as carriers to carry other components of the pipe cleaning machine, their weight is usually heavy. Therefore, in the process of stretching the upper fuselage 10 and the lower fuselage 20 apart through the relative movement of the fixed body 51 and the movable body 52, the force on the connection node between the upper fuselage 10 and the fixed body 51 is also relatively large. In this embodiment, the first fixing column 11 is fixed in cooperation with the mounting hole 511, so that the force on the connection node between the upper fuselage 10 and the fixed body 51 can be evenly distributed along the 360° direction of the mounting hole 511 and the first fixing column 11, thereby avoiding stress concentration in a certain direction, which may cause the mounting hole 511 or the first fixing column 11 to break or be damaged, and effectively increasing the connection strength of the connection node, so that the connection between the fixed body 51 and the upper fuselage 10 is stable and reliable.

[0049] Furthermore, in the present application, a connection seat 70 is further provided between the first fixing column 11 and the mounting hole 511, and the connection seat 70 includes a seat head 71 and a seat body 72 connected to each other, the seat head 71 is connected to the first fixing column 11, and the seat body 72 is detachably plugged into the mounting hole 511. In this embodiment, the connection seat 70 is roughly T-shaped in appearance, the seat head 71 and the seat body 72 are an integrated structure with good structural strength and easy processing and forming, the seat head 71 can be sleeved on the first fixing column 11, and the seat body 72 is plugged into the mounting hole 511, thereby, the connection seat 70 can be conveniently and quickly installed and disassembled. Since the upper body 10 and the lower body 20 are used as carriers to carry other parts of the pipe cleaning machine, they are usually heavy. Therefore, in the process of stretching the upper body 10 and the lower body 20 by the relative movement of the fixed body 51 and the movable body 52, the connection node between the upper body 10 and the fixed body 51 is also subjected to a large force. Therefore, in the process of repeated telescopic movement of the upper body 10 and the lower body 20, the part where the mounting hole 511 and the first fixing column 11 are connected is very easy to cause wear, and the fixed body 51 and the first fixing column 11 provided on the upper body 10 are difficult to repair, and the maintenance cost is high. In this embodiment, by detachably providing the connecting seat 70 between the mounting hole 511 and the first fixing column 11, the connecting seat 70 is transitionally connected, so that when the connecting seat 70 is worn, it can also be easily and quickly replaced, and the cost of the connecting seat 70 is low, which greatly reduces the maintenance cost.

[0050] In one embodiment of the present application, one end of the movable body 52 has a connection hole 521, and a second fixing column 21 is protruding from 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 can be detachably fixed to the second fixing column 21. It can be understood that the connection hole 521 can also be a circular hole, and the second fixing column 21 is a matching circular column, and the connection hole 521 and the second fixing column 21 can be fixed by interference fit. Since the upper fuselage 10 and the lower fuselage 20 are used as carriers to carry other components of the pipe cleaning machine, their weight is usually heavy. Therefore, in the process of stretching the upper fuselage 10 and the lower fuselage 20 apart by the relative movement of the fixed body 51 and the movable body 52, the connection node between the lower fuselage 20 and the movable body 52 is also subjected to a large force. In this embodiment, the second fixing column 21 is fixed in cooperation with the connecting hole 521, so that the force borne by the connection node between the lower fuselage 20 and the movable body 52 can be evenly distributed along the 360° direction of the connecting hole 521 and the second fixing column 21, thereby avoiding stress concentration in a certain direction, which may cause the connecting hole 521 or the second fixing column 21 to break or be damaged, and effectively increasing the connection strength of the connection node, so that the movable body 52 and the lower fuselage 20 are stably and securely connected.

[0051] Further, please refer to Figures 1 to 3 The pipe cleaning machine of the present application further includes an auxiliary support mechanism 60, one end of which is connected to the upper fuselage 10, and the other end is connected to the lower fuselage 20, so as to support the upper fuselage 10 and the lower fuselage 20. It can be understood that by providing the auxiliary support mechanism 60, after the upper fuselage 10 and the lower fuselage 20 are relatively spread apart by a certain distance, for example, when the upper fuselage 10 is spread apart upward relative to the lower fuselage 20, the auxiliary support mechanism 60 can support and bear the gravity of the upper fuselage 10, so as to avoid the gravity being completely concentrated in the telescopic mechanism 50, effectively protecting the telescopic mechanism 50, and improving the safety and reliability of the pipe cleaning machine.

[0052] In one embodiment, the auxiliary support mechanism 60 includes a support rod 61, which is obliquely arranged between the upper body 10 and the lower body 20, and one end of the support rod 61 is hinged to the upper body 10, and the other end is hinged to the lower body 20. The support rod 61, which is obliquely arranged and hinged to the upper body 10 and the lower body 20, can form a similar rocker mechanism during the relative movement of the upper body 10 and the lower body 20. When the upper body 10 and the lower body 20 are in a relatively contracted state, the support rod 61 does not provide a supporting force but is in a relatively gentle state; when the upper body 10 and the lower body 20 are in a relatively open state, the support rod 61 is in a relatively steep state and supports the upper body 10, thereby preventing gravity from being completely concentrated in the telescopic mechanism 50, effectively protecting the telescopic mechanism 50, and improving the safety and reliability of the pipeline cleaning machine.

[0053] In another embodiment, the auxiliary support mechanism 60 is a compression spring structure, which provides partial support force through the compression spring structure, so that when the upper fuselage 10 and the lower fuselage 20 are in a relatively open state, part of the gravity is distributed to the compression spring, thereby avoiding the telescopic mechanism 50 from bearing the full weight and causing overstrain.

[0054] In one embodiment of the present application, the telescopic mechanism 50 is hinged to the upper body 10 and the lower body 20, and is tilted between the upper body 10 and the lower body 20, and the tilt direction of the telescopic mechanism 50 is set at an angle with the tilt direction of the support rod 61. It can be understood that the tilted telescopic mechanism 50 can provide sufficient installation space for other installation components, such as the running wheels 41 and the auxiliary wheels 42, after connecting the upper body 10 and the lower body 20, without affecting the normal rotation of the running wheels 41 and the auxiliary wheels 42, making the overall structure more compact. At the same time, the tilt design of the telescopic mechanism 50 in conjunction with the support rod 61 meets the mechanical properties, making the movement process of the upper body 10 and the lower body 20 more labor-saving and reliable.

[0055] In actual applications, the telescopic mechanism 50 and the auxiliary support mechanism 60 are cross-arranged between the upper fuselage 10 and the lower fuselage 20. Therefore, when the telescopic mechanism 50 moves to spread the upper fuselage 10 and the lower fuselage 20 apart, for example, when adapting to the change in pipe diameter from 300 mm to 400 mm, in order to make the running wheels 41 and the auxiliary wheels 42 fit tightly against the inner wall of the pipe, the telescopic mechanism 50 extends and drives the auxiliary support mechanism 60 to rotate, thereby jointly supporting the upper fuselage 50 and the lower fuselage 60 apart. By increasing the distance between the auxiliary wheels 42 and the running wheels 41 to adapt to the increase in the size of the pipe, the contraction movement to adapt to the small pipe diameter can be obtained in the same way.

[0056] In another embodiment, please refer to reference 5, the telescopic mechanism 50 is vertically arranged between the upper body 10 and the lower body 20. When it is necessary to clean a pipe with a larger diameter, the telescopic mechanism 50 is lifted and the upper body 10 moves relative to the lower body 20, so that the walking wheels 41 and the auxiliary wheels 42 can both abut against the inner wall of the pipe and move along the inner wall of the pipe for cleaning.

[0057] Please refer to Figure 6 In another embodiment of the present application, the auxiliary support mechanism 60 includes a plurality of connecting rods 62, which are staggered between the upper body 10 and the lower body 20 and can be folded or stretched between the upper body 10 and the lower body 20. In this embodiment, the auxiliary support mechanism 61 is formed as a folding telescopic rod structure. When the folding telescopic rod is folded, the upper body 10 and the lower body 20 are close to each other, so as to adapt to the cleaning of small-diameter pipes; when the folding telescopic rod is stretched, the upper body 10 and the lower body 20 are far away from each other, so as to adapt to the cleaning of large-diameter pipes. In this structure, the telescopic mechanism 50 and the auxiliary support mechanism 60 cooperate with each other and jointly support the upper body 10 and the lower body 20, and the auxiliary support mechanism 60 has more force points with the upper body 10 and the lower body 20, and the force bearing area is large, so as to ensure that the pipeline cleaning machine can remain stable and reliable.

[0058] Furthermore, the spray head assembly 30 of the present application includes a mounting seat 32 and a spray head 31 for spraying cleaning water, wherein the mounting seat 32 is mounted on the lower body 20, and the spray head 31 is rotatably connected to one end of the mounting seat 32 away from the lower body 20. In this embodiment, the spray head 31 can be connected to the mounting seat 32 through a small rotary motor, so that the spray head 31 can rotate relative to the mounting seat 32, or the spray head 31 is circumferentially provided with a plurality of spray holes, and the sprays of the plurality of spray holes form a vortex, so that the spray head 31 itself is rotated by the high-pressure spray flow, so that when the spray head 31 moves along the pipeline, the rotating spray head 31 sprays high-pressure cleaning water, so that the cleaning water can flush the inner wall of the pipeline in a 360° direction, thereby greatly improving the cleaning degree of the pipeline.

[0059] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
