Urban drainage pipeline dredging robot

Abstract

The invention discloses an urban drainage pipeline dredging robot, which comprises a vehicle body. A power cavity is formed in the vehicle body, a standby cavity located on the left side of the powercavity is formed in the vehicle body, a power shaft extending into the standby cavity is rotatably connected in the power cavity, the power shaft is in power connection with a motor fixedly connectedto the inner wall of the right side of the power cavity, the power shaft is rotatably connected with a cross rotating table located on the left side of the motor, four self-adaptive devices located onthe left side of the motor are distributed in the power cavity in the circumferential direction in an array mode, and the ends, away from the centers, of the four self-adaptive devices extend out ofthe end face of the power cavity; when a dredging robot encounters obstacles or the pipe diameter changes, the plurality of sets of scrapers adapt to the environmental change by sliding to change thedistance between, the scrapers drive a first crawler device to rotate through a linkage mechanism, a second crawler device can also adapt to the environmental change by sliding to change the distancebetween, and thus efficient obstacle crossing and in-pipe traveling auto adaptation the dredging robot are realized.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging robots, in particular to a dredging robot for urban drainage pipelines. Background technique [0002] Urban drainage pipes are engineering facility systems for treating and removing urban sewage and rainwater. Urban drainage pipes are usually buried underground. Because a large amount of domestic debris and garbage are discharged into the drainage pipes and cement sand on the infrastructure construction site is deposited and silted, it is easy to cause pipe blockage. If the pipeline is not dredged and dredged in time, it will easily lead to excessive sewage flow, environmental pollution and urban waterlogging. However, the environment where the pipeline is located is often difficult to reach directly or does not allow people to directly enter. An effective method is to use pipeline robots to complete the pipeline dredging work. Most of the existing pipeline dredging robots cannot perform...
