Embodiment

[0025] This embodiment is a traveling mechanism used in underground micro-pipeline excavation construction. Driven by a motor, the traveling mechanism moves forward to push the front cutter head to carry out pipeline excavation. The diameter of the pipeline is 20cm, and the pipeline laying environment is a soil environment.

[0026] Refer to attached figure 1 , this embodiment includes a power mechanism, a support bracket 5 and a transmission adjustment mechanism.

[0027] The power mechanism includes RV reducer 2 and 4 driving sprockets 3. The RV reducer 2 is connected to the external power input shaft 1. The power input shaft 1 is the power input of the external motor. The 4 driving sprockets 3 are respectively fixed on the RV reducer 2 The two ends of the two power output shafts are connected with the key of the power output shaft, the power output shaft is perpendicular to the power input shaft, and the two power output shafts are symmetrically placed one up and one down, ...

Abstract

The invention provides an adjustable adaptive traveling mechanism in a pipeline, which can be applied to various pipeline projects. In the traveling mechanism, a chain can be tensioned by arranging a chain tensioning mechanism; parallel motion of parallel brackets is realized through an adjusting mechanism; the traveling mechanism has the function that the distance between the two parallel brackets can be automatically adjusted according to looseness of soil, so that the chain is contacted with the soil all the time; and a chain with an accessory ensures that the chain is effectively contacted with the soil during movement to produce sufficient forward thrust.

Description

technical field [0001] The invention relates to the field of mechanical running mechanisms, in particular to an adjustable self-adapting internal running mechanism in a pipeline. Background technique [0002] In projects such as pipeline flaw detection and micro-pipeline excavation, it is often necessary for the machine to have the function of advancing by itself under power drive. At present, the pipeline inspection robot developed by Tsinghua University adopts a full-drive straight-forward structure. Three DC motors drive three radially evenly distributed drive wheels through worm gears, and a scissor spring compression mechanism tightens the drive wheels. The pipe wall moves by friction; the small mobile robot in the pipe developed by Shanghai University follows the rotation of the motor, the driving mechanism performs a spiral motion, the holding mechanism moves along the central axis of the pipe, and the polarity of the current applied to the motor can be changed to cha...
