Description

Technical Field

[0001] The utility model relates to a water pipeline desilting device, belonging to the technical field of pipeline desilting. Background Art

[0002] Pipeline desilting refers to clearing the pipeline, cleaning the silt and other waste inside the pipeline, and keeping it unobstructed for a long time. If the pipeline is not desilted regularly, it will cause sewage overflow and environmental pollution.

[0003] The Chinese utility model patent with publication number CN211816873U discloses a municipal pipeline dredging robot. The robot body is provided with robot tracks evenly distributed along the circumferential direction of the robot body. The robot tracks are connected to the robot body through an electric screw. The electric screw contains a micro motor. The micro motor controls the extension and retraction of the screw to control the track spacing to adapt to pipelines of different sizes.

[0004] The distance between the tracks of the above-mentioned dredging robot and the circumference of the robot body needs to be controlled by an electric screw. The electric screw and the tracks are arranged in a one-to-one correspondence. There are multiple tracks, so the number of electric screws and motors required is also multiple.

[0005] The distance between the walking parts and the main body is controlled by multiple driving parts. The synchronization of the adjustment process of the distance between different walking parts is poor, and the distance between different walking parts cannot be accurately consistent. In addition, the control of the distance between the walking parts by multiple driving parts makes the overall production cost of the equipment higher and increases the difficulty of control.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] Furthermore, the sprocket is drivingly connected to the first drive motor, and the first drive motor synchronously drives the multiple sprockets to rotate.

[0021] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0033] The number of the driven wheel sets 3 is at least two, and the driven wheel sets 3 and the driving wheel sets 2 are evenly distributed around the periphery of the main housing 1 in a circumferential manner.

[0034] A turntable 5 is provided at the front end of the main housing 1 along the moving direction. A plurality of scrapers distributed in a circumference are installed on the periphery of the turntable 5. The turntable 5 drives the scrapers to rotate at a high speed to remove the silt on the inner wall of the water delivery pipe 8.

[0035] The axes of the turntable 5 and the main housing 1 are colinearly arranged. The turntable 5 is mounted on the output shaft of the second drive motor 7 , and the second drive motor 7 is fixedly mounted in the main housing 1 .

[0036] The tightening mechanism 4 includes a support arm 41, which is arranged parallel to the axis direction of the main housing 1. The support arm 41 is used to install the driving wheel set 2 and the driven wheel set 3. An X-shaped folding arm is installed between the support arm 41 and the outer wall of the main housing 1. The X-shaped folding arm drives the support arm 41 to move during the folding process, thereby adjusting the distance between the support arm 41 and the outer wall of the main housing 1.

[0037] The X-shaped folding arm comprises a first oblique arm 42 and a second oblique arm 43 which are hingedly connected. The middle parts of the first oblique arm 42 and the second oblique arm 43 are hingedly connected.

[0038] One end of the first oblique arm 42 is connected to the outer wall of the main housing 1 through a hinge support, and the other end of the first oblique arm 42 is connected to the end of the support arm 41 through a hinge support.

[0039] One end of the second inclined arm 43 is hingedly connected to a nut 44 , and the nut 44 is fixedly mounted on a first slider 45 . The first slider 45 is slidably disposed on a first slide rail 46 on the outer wall of the main housing 1 , and the first slide rail 46 is fixedly connected to the outer wall of the main housing 1 .

The rotation of the lead screw 47 drives the nut 44 and the first slider 45 to move along the first slide rail 46. Since the nut 44 is hinged with the second inclined arm 43, the nut 44 drives the X-shaped folding arm to fold during the movement. The folding process expands the distance between the support arm 41 and the outer wall of the main shell 1, and then presses the driving wheel group 2 and the driven wheel group 3 against the inner wall of the water pipe 8; then the driving wheel group 2 drives the whole machine to move in the water pipe 8, and at the same time, the second drive motor 7 drives the turntable 5 and the scrapers around it to rotate at high speed to remove the silt on the inner wall of the water pipe 8.
