Definitions
- patent CH 672 895 describes a machining device operating inside a pipe, consisting of several modules coupled together, one of which is a specialized work module; this train of modules is pulled by the traction device which is the subject of patent CH 669 127 characterized in that its advance movement is done in spurts, resulting from a succession of elongation and retraction movements of the body of said device, radial expanders coming to bear on the inner wall of the pipe. If this traction device works properly, it is of relatively complicated construction and use, due to its successive movements of elongation and retraction.
- Another toothed wheel 26 is fixed on the same axis 11A, preferably on the other side of the caster 11, and drives the toothed wheel 27, fixed on the axis 12A of the caster 12 by means of another chain galle 28.
- the motor 20 is preferably a DC motor, it is capable of turning in one direction or in the other, variable speed, depending on the voltage applied to it; therefore the drive of the traction device will also be in one direction or the other, at variable speed.
- the rear face 17 of the body 10 comprises various members not shown, in particular pivoting, articulated and flexible coupling means making it possible to fix the next module, one or more connectors for fixing the energy transmission cable or cables and / or control signals, as well as a switch for controlling the forward or reverse movement of the device from said panel when the device is being introduced into the pipe, as well as the postponement of the control of walk to a control panel located outside the excavation.
