[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) This invention is used, for example, to open and close a cable wiring support bracket to perform cable wiring work at a high place in a building. It relates to an operating device.

(Prior Art) Generally, when various cables are wired in a high place of a building, for example, in a ceiling in a room, they are supported by a number of hanging rod members such as hanging bolts hanging from the ceiling.

The support is achieved, for example, by fixing a support fitting having a groove-shaped support part to the hanging rod member and inserting a cable into the support part. When supporting cables, since the cable wiring is supported at a high place, a stepladder is used as a foothold, and the work is carried out by moving the stepladder along the wiring direction and repeatedly climbing up and down.

(Problems to be solved by the invention) According to the conventional work method described above, it is extremely troublesome, dangerous, and inefficient because it requires moving, setting, and getting on and off the stepladder. It is true.

Therefore, this idea was devised in view of the existing points mentioned above, and it is extremely simple and easy to remove cables by performing work directly from the work floor without using a stepladder or the like. Wiring can be supported at high places, and the cable running height is
The purpose of the present invention is to provide an opening/closing operation device for a cable wiring support fitting to a high place, which allows work to be carried out according to the height of a worker.

[Structure of the device] (Means for solving the problem) In order to solve the problems of the conventional method, this device has a suspension rod member in a predetermined position in order to enable direct work from the work floor. Prepare a support bracket that can be gripped and set in an open/close manner at a height position, support the cable on this support bracket, attach the expanded support bracket to the tip, and hold it to the wiring support position. The support fitting is then gripped and attached to the hanging rod member by a closing operation on the support fitting.

Specifically, it includes a substantially groove-shaped fixing piece that elastically grips and fixes the hanging rod member, and an operation hole that is connected to both sides of the opening edge of this fixing piece and that forcibly expands the fixing piece. We have brought a support metal fitting that is integrally formed with a pair of left and right expansion operation pieces and a substantially groove-shaped support piece through which the cable is inserted and supported. The opening/closing operation device includes an operation jig having a height that extends from the work floor to a cable support position, and an expansion operation provided at the upper end of the operation jig to forcibly expand the fixed piece. A grip part that engages with the piece and supports the support fitting itself, an operation part that is provided at the lower end of the operating jig and remotely controls the expansion of the grip part, and a slidable position on the lower end of the operating jig. A telescopic adapter is attached thereto and has a remote control section that is connected to the operating section to remotely control the operating section.

(Function) The device for opening/closing the wiring support fittings for cables to high places according to this invention can be used to operate hanging rod members suspended from structural support materials such as ceiling slabs and steel frames on the work floor. A worker performs cable wiring support work by remotely controlling the supporting metal fittings via the opening/closing operation device of this invention.

That is, first, the operating jig is slidably positioned and adjusted, and a telescopic adapter is attached to the lower end of the operating jig by linking the remote control section to the operating section, and the support height of the cable on the hanging rod member is adjusted. Adjust the overall length according to the position, height of the worker, etc.

Separately, a support metal fitting is attached to the grip portion at the upper end of the operating jig, and a cable to be wired and supported is inserted and supported through the support metal fitting.

The operating jig supporting the cable via the support fitting is lifted to the position of the hanging rod member corresponding to the supporting height position of the cable, and the remote control section of the telescopic adapter attached to the lower end of the operating jig is operated. The operation of this remote control section opens and closes the grip section through the operation section of the operating fixture, and thereby opens and closes the groove-shaped fixing piece opening of the support fitting to the hanging rod member by remote control. .

Apply the fixed piece in the open state to the hanging rod member and fit it. After fitting, when the opening operation on the fixing piece is released and the fixing piece is closed, the fixing piece grips the hanging rod member, and then the grip portion is removed from the support fitting.

The supporting metal fittings left behind while gripping the hanging rod members support the cable, and by repeating this in sequence along the arrangement between the suspended hanging rod members, the cable can be held at a predetermined height. Support wiring.
