1. A moving device in pipe lines, comprising:
- an inside magnet line in which three or more magnet elements are interconnected in the direction of magnet flux;
an outside magnet element line which is provided slidably on the outside of the magnet elements of the inside magnet line;
a switching means which switches the magnet poles of the inside magnet elements and the corresponding pair of the outside magnet elements in-phase or reversed phase; and
a control means for controlling the each switching means by a preset program;
wherein said preset program instructs said switching means to switch the magnet poles of the inside magnet elements and/or the corresponding pair of the outside magnet elements to move the outside magnet elements via the attractive force and repelling force of the magnet poles; and
wherein the movement of the outside magnet elements is a driving force for the movement of the moving device.

Abstract
A moving device in pipe lines is provided, which allows easy switching of moving/stopping and remote control of the switching by only electric wires enabling easy operation in the inside of small diameter pipe lines.
The moving device 10 in pipe lines comprises a guide frame 11 in which a line of three or more coils 15, 16, 17 is interconnected flexibly in the direction of magnet flux, ring-shaped permanent magnets 19, 20, 21 provided around the periphery of the guide frame slidably in the direction of the shaft, and a control means such as computers etc. to control by a preset program selecting the direction of turning on of the coils.

8. A moving device in pipe lines, comprising:
-
a magnet line in which three or more electromagnets are interconnected; a guide member which guides the magnet lines slidably; and a distributor for controlling the magnet poles of said electromagnets by a preset program, wherein the distributor is located in each electromagnet and comprises the controlling part to control the poles of the electromagnet by a preset program and the controller which gives instructions to the controlling part of the end distributor;
the controlling part of the electromagnet is provided with the receiver which receives the instructions to move, the operation part which performs an arithmetic operation of the magnets and controls the magnets by the program in which the instructions to move obtained from the receiving part and the information of the object magnet pole of the magnet element are used as an argument, and is provided with the transmitter which transmits the instructions to move to the controlling part of the electromagnet after the control of the pole by the operation parts;
the receiving part and the transmitting part transmit the instructions to move from the end electromagnets to front electromagnets or from the front electromagnets to the end electromagnets. - View Dependent Claims (21, 22)

9. A moving device in pipe lines, comprising:
-
three or more segments; an interconnecting means which interconnects these segments; a driving means which drives the interconnecting means so as to move these segments to the remaining segments relatively; and a control means to control the driving means, wherein the controlling means comprises a controlling parts provided in each segment and a controller which gives instructions to move to the end controlling part;
the controlling part comprises a receiving part which receives instructions to move, an operation part which drives the driving means by computing the conditions of the object driving means using the information of the instructions to move obtained from the receiving part and the conditions of the object driving means as an argument, and a transmitting part which transmits the instructions to move to the controlling part of the other driving means after the control of the driving means by the operation part;
the each receiving part and the transmitting part transmits the instructions to move from the end driving means to the front driving means or from the front driving means to the end driving means in sequence;
the engaging force with the inside of pipe lines of the moved segments are smaller than that of the remaining segments.
