Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting tool used for attaching a device such as a switch for construction to a utility pole during distribution work, for example.

[0002]

[Prior art]

 To attach various devices to a utility pole, needless to mention specific examples, combine separate band pieces and tighten them to the utility pole with tightening bolts and tightening nuts. A support material is attached to a so-called utility pole band composed of, and equipment is attached to the support material to mount the equipment.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, a pole pole band composed of band pieces is mounted, and thereafter, a device is supported by a support member by this, so that the pole mounting work of the pole pole is complicated, and therefore the distribution pole is It cannot always be said that it is practical as a pillar tool used for temporarily mounting equipment such as a work switch that is installed only during construction.

In view of such a conventional example, the present invention has been devised for the purpose of providing a suitable pillaring tool as a device for temporarily mounting a comparatively lightweight device.

[0005]

[Means for Solving the Problems]

 One side of the first and second pair of band pieces is pivotally attached to one end of a base frame that freely assembles and supports equipment such as construction switches so that the vertical axis can be rotated to correspond to the outer shape of the utility pole. The one end of each of the arc-shaped first and second band pieces is connected to each other by a tension spring, and a tightening receiving piece is provided on the other end of the first band piece. A tightening receiving piece that supports the base portion of the tightening bolt on the receiving piece and supports the tightening nut screwed to the tip of the tightening bolt is provided at the other end of the second band piece.

【Example】

 The drawing shows one embodiment of the pillar tool A of the device according to the present invention, FIG. 1 is a cross-sectional view showing a use state, FIG. 2 is a partially cutaway front view, and FIG. 3 is a state in which a band piece is opened. It is a plan view.

In the figure, reference numeral 1 denotes a base frame having a U-shaped cross section in which a support piece 1c is arranged between an upper piece 1a and a lower piece 1b. The support piece 1c of the base frame 1 has a pair of horizontally long slots 2 , 2 are provided, the bolt 3 protruding from the device B is passed through the elongated holes 2 and 2, and the nut 4 is screwed into the bolt 3 and tightened so that the base frame 1 and the device B are assembled to each other. There is.

[0008] One ends of the upper and lower pieces 1a and 1b of the support base frame 1 corresponding to the support portion pieces 1c are formed as arc-shaped edges 5 so as to correspond to the outer shape of the electric pole D. The U-shaped pieces 9 and 9 provided on one side of the first band piece 7 and the second band piece 8 are interposed between the piece 1a and the lower piece 1b, and the U-shaped piece 9 and the upper and lower pieces 1a and 1b are connected to each other. The first and second band pieces 7 and 8 are pierced by the base frame 1 by penetrating the pivot bolt 10 and screwing a nut 11 onto the tip of the pivot bolt 10 devised from the lower piece 1b. It is rotatably and pivotally attached to.

A tension spring 12 is shown in the figure. Each end of the tension spring 12 is engaged with a terminal piece 13, 13 provided at the one end of the band piece 7, 8 so that each band piece 7, The other end on the other side 8 is separated from each other by the urging force of the tension spring 12, and the separation width is long enough to allow the utility pole D to move in and out.

The first and second band pieces 7 and 8 have an arc shape corresponding to the outer shape of the electric pole D, and are formed in an annular shape which forms the end portion on the other side of the first band piece 7 and are tightened. The tightening bolt 16 is assembled by screwing the base portion of the tightening bolt 16 to the nut material 15 engaged with the tightening receiving piece 14, and the tip of the tightening bolt 16 is passed through the horizontally long window 17 provided in the tightening receiving piece. It is projected and the tightening nut 18 is screwed.

The tightening nut 18 is selected at a position where it is locked to a tightening receiving piece 19 provided at the other end of the second band piece 8 and is screwed to the tightening bolt 16.

The tightening receiving piece 19 of the second band piece 8 is composed of a pair of flat plate bodies welded to both ends of the band piece 8, and the ends are slightly cut out to prevent the tightening nut 18 from coming off. In addition, the guides 20 for inserting the tightening bolts in the inverted C-shape are provided by bending the upper portions outwardly.

Therefore, in order to attach the device B to the telephone pole D, the equipment A is attached to the back surface of the equipment B by the existing method, and the equipment A is attached to the back surface. B is lifted to a predetermined mounting position of the electric pole D, the electric pole is fitted and inserted between one side of the pair of band pieces 7 and 8, and the electric pole D is inserted to the innermost end of the pillar fixture A. Since a tension spring 12 is attached between one side of the pair of band pieces 7 and 8, the band pieces 7 and 8 are necessarily separated from each other to have a space for inserting a utility pole. It does not need to be fixed and the operation is smooth.

Next, the inserted electric pole D is brought into contact with the base portion of the terminal piece 13 on one side of the first band piece 7 and the second band piece 8 and is further pressed, whereby the first band piece 7 and the second band piece 8 are pressed. 8 is pivoted around the pivot bolt 10 and is automatically closed. Therefore, by simply pushing the device against the electric pole D, both band pieces 7 and 8 are in a state of holding the electric pole D. Thereafter, the tightening bolt 16 having the base portion assembled to the tightening receiving piece 14 of the first band piece 7 is rotated to the fulcrum of the base portion, and the tip end side is provided on one side of the second band piece 8 with the tightening receiving piece 19. The device B can be easily attached to the utility pole D by hooking it on the device and tightening the tightening nut 18.

When removing the device B, the nut 18 is loosened, and the tightening bolt 16 is removed from the second band piece 8 to remove the device B. The first band piece 7 and the second band piece 8 rotate about the pivot bolt 10 to automatically expand and can be easily removed from the utility pole D.

[0016]

[Effect of device]

 According to the present invention, since the opening and closing operation of the first band piece and the second band piece is automatically performed, the attachment and detachment operation is easy and there is no need to remove the tightening bolts and nuts. It is excellent in workability and safety, and practical because it allows the worker to work at a fixed work position.
