Abstract

PROBLEM TO BE SOLVED: To easily mount and demount a nut member by engaging a small diameter gear on a shaft rod supported by an U-tube, with a large diameter gear mounted on an outer peripheral surface of the nut member, and rotating the shaft rod by a tool when a pipe line is switched by exchanging a movable side pipe opening with nut member to a fixed side pipe opening. SOLUTION: To exchange a U-pipe 6, the nut members 9, 10 mounted on the movable side pipe openings 4, 5 are disengaged from the male screws 8 formed on the fixed side pipe openings 2, 3 and reengaged with the same. On this occasion, a small diameter gear 19 and a large diameter gear 11 are engaged with one another by engaging a square hole 24 formed on a point of an arm member 22 with a square shaft 15 for mounting and demounting an arm mounted on an upper end of a shaft 13 corresponding to a pipe to be demounted, and engaging a shaft supporting hole 29 with an upper end 30 of the shaft 13. In this engagement state, a spanner is applied to a square shaft 25 for application of tool to rotate a shaft rod 18, that is, the small diameter gear 19, and its rotation is transmitted to the large diameter gear 11, that is, the nut member 9 to demount the nut member 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, movable-side piping ports are provided at both ends with respect to fixed-side piping ports 2, 3 provided at a central point of a fixed plate 1 and a circular line centered at the central point. The present invention relates to a pipeline switching device of a type in which pipelines are switched by arbitrarily changing a U-shaped pipe 6 having pipes 4 and 5 and provided on an outer peripheral surface of an edge portion of fixed-side piping ports 2 and 3. The male thread 8 and the nut members 9 and 10 attached to the rims of the movable-side piping ports 4 and 5 so as to be freely rotatable and cannot be removed so as to perform the above-mentioned optional reconnection operation. Large diameter gears 11 and 12 are formed on the outer surface by forming teeth on the outer surface, and support shafts 13 and 14 are erected at positions near both ends of the outer curved surface of the U-tube 6. At the tip of the short square arm mounting and demounting square shafts 15, 16 are provided and separately from this.
A small-diameter gear 1 which can be meshed with the large-diameter gears 11 and 12 at the lower end.
9 is provided, and a small diameter portion 20 is provided at the upper end of the shaft rod 18, and the arm member 21 cannot be removed from the small diameter portion 20 via a washer 22 and a bearing metal 23 and cannot be removed. The arm member 22 is freely supported, and a connection square hole 24 is provided at the tip of the arm member 22 so as to be freely fitted to the arm attachment / detachment square shafts 15 and 16.
When the gears are engaged with the large-diameter gears 11, 12
And the upper end of the shaft rod 18 protrudes above the arm member 22, and the protruding portion is a square shaft 25 for hooking a tool such as a hexagonal spanner.

Reference numeral 27 in the figure denotes a proximity switch which responds to the position of the tip of a rod 28 erected on the inner curved surface of the U-tube 6.
Reference numeral 29 denotes a bearing hole for allowing the upper end portions 30 of the support shafts 13 and 14 to be rotatably fitted so as to smoothly rotate the arm member 22 along one horizontal plane. Reference numeral 31 denotes a seal.

When the U-shaped tube 6 is replaced in the above embodiment, it is necessary to remove the nut members 9 and 10 from the male screw 8 or to reconnect them. The small-diameter gear 19 is formed by fitting the arm mounting / removing square shaft 15 provided at the upper end of the support shaft 13, the square hole 24 provided at the tip end of the arm member 22, the upper end 30 of the support shaft 13, and the shaft bearing hole 29. The large-diameter gear 11 is meshed, and in this meshed state, a wrench (not shown) is hung on the tool-holding angular shaft 25, and the shaft rod 18, that is, the small-diameter gear 1 is rotated.
9 and the rotation of the small-diameter gear 19 causes the large-diameter gear 11 to rotate.
That is, this is removed by turning the nut member 9,
When it is desired to reconnect, the nut member 9 is screwed into a position where it can be turned manually, and then the small-diameter gear 19 and the large-diameter gear 11 are meshed in the same manner as in the case of the above-mentioned disassembly. The nut member 9 is used by rotating the nut member 9 and the like.

[0009]

The manual pipeline switching device according to the present invention is as described above. Therefore, by turning the outer end of the shaft of the small-diameter gear with a tool such as a spanner, the nut member is detached, that is, the nut member is movable relative to the fixed-side piping port. It is possible to disconnect or reconnect the side piping port, and in the case of U-tube replacement work, there is no need to directly apply a tool such as a spanner to a nut member that is located in a recessed narrow place, The same work can be performed by hanging a tool such as a wrench on the outer end of the shaft rod existing in the open space, and the inconvenience in use as described above and the insufficiency in space saving and miniaturization are all excluded. It can be eliminated.
