Problems solved by technology

However, the diameter of optical cable pipes is generally in the range of 150-200 mm, with various specifications, and pipe deformation and blockage will affect the pipe diameter. The existing pipe robot walking device is far from being able to meet such complex pipe diameter requirements.

Abstract

The invention discloses a cable embedded pipe expanding robot, which comprises a cable embedded pipe traveling device, a pan-tilt, an expansion mechanism and a central processing unit. The embedded pipe traveling device comprises a traveling drive motor and a plurality of traveling wheel components peripherally and uniformly distributed along a spindle. Each traveling wheel component comprises a wheel leg and supporting arms, wherein two ends of each supporting arm are hinged to the wheel leg and the spindle respectively. The drive motor drives the wheel legs. A diameter-variable mechanism comprises a diameter-variable drive motor, diameter-variable connecting rods and a lead screw transmission mechanism. Two ends of the each diameter-variable connecting rod are hinged to a slider and thecorresponding supporting arm respectively. The diameter-variable drive motor changes the expansion mechanism comprising expansion push rods and an expansion drive motor through inclination of the supporting arms pushed by the diameter-variable connecting rods and the lead screw transmission mechanism. The central processing unit controls the traveling drive motor, the diameter-variable drive motorand the expansion drive motor to enable the robot to travel to a pipe recess, and the expansion push rods push the recess outwards to repair a recessed pipe.

Description

technical field [0001] The invention relates to the technical field of pipeline robots, in particular to a cable pre-embedded pipeline expansion robot. Background technique [0002] Underground cables and communication optical cables are important components of the power system and the basis for ensuring the reliability of power supply. Now more and more cities use underground cable transmission and distribution to replace overhead transmission lines. As a necessity for underground cable laying, cable ducts are rapidly increasing in use. [0003] During the use of the cable duct, the duct will be deformed, especially the sunken deformation of the duct, which makes the cable unable to pass through. If the sunken cable duct is not repaired in time, accidents may occur, which will affect the construction progress and cause unnecessary losses. [0004] Therefore, pipeline robots are usually used to expand and repair sunken cable ducts. However, the diameter of the optical cab...
