Description

  The present invention relates to an adapter that is detachably attached to a remote operation gripping device that grips an overhead wire or other parts by remote control in a protective tube installation work.

  When a heavy object is lifted in construction work such as a house, an aerial work vehicle such as a crane truck is often used. And in such an aerial work vehicle, in order to prevent the wire rope of the aerial work vehicle or a load suspended from the wire rope from coming into contact with an aerial distribution line installed nearby, for example, a wire It is known that work is performed while attaching a flag or the like as a mark to a rope or baggage to call attention. However, in such construction, it is also possible that an operator overlooks an overhead distribution line even if he / she is working with the mark, and in such a case, an aerial work vehicle or an operator receives an electric shock, There was a risk of injury. For this reason, conventionally, in order to make it easier to recognize the presence of an overhead distribution line that should not be touched and to call attention, construction has been carried out with the overhead distribution line covered with a protective tube.

Here, the work of attaching the protective pipe to the overhead distribution line has been efficiently performed in recent years by using a hydraulic high-pressure protective pipe insertion machine (see, for example, Patent Document 1). For example, as shown in FIGS. 6A and 6B, two workers get on the work platform of an aerial work vehicle, and one of them operates a hydraulic high-pressure protective pipe insertion machine, and others. The protection tube is attached by one person holding the protection tube. Such a hydraulic high-pressure protective tube insertion machine is suitably used when, for example, it is necessary to protect a long-distance electric wire, and the protective tube is connected to the interior state while being connected.
JP 2000-197225 A

  However, since the hydraulic high-pressure protective tube insertion machine described in Patent Document 1 is a large-scale device equipped with a hydraulic motor, there is a problem that it cannot be used in a narrow place. For example, in places where the road width is narrow and high-altitude work vehicles cannot enter, the high-pressure protective pipe insertion machine cannot be used because the hydraulic power of the high-altitude work vehicle is used as the power source to drive the hydraulic motor. It was.

  Therefore, a manual type protective tube insertion machine has been used to install the protective tube in such a place. A manual type protective tube insertion machine needs to attach a protective tube to a wire that is energized while ensuring insulation from the operator. The attached one is used. Moreover, since the protective tube used in such a place has a length of about 3 meters, the protective tube is usually installed at the tip of the operation rod in addition to the protective tube insertion machine. A remote control gripping device is used that grips a protective tube by operating the gripping device with an operation unit provided on the other end side of the operating rod.

  Here, each of the gripping devices for remote operation is curved, and an operator operates an operation unit connected to the gripping unit with a gripping unit including a pair of arms for gripping an aerial distribution line and the like at the curved portion. It has a structure that grips overhead distribution lines and the like. Therefore, for example, when a manual type protective tube insertion machine that is mounted while expanding the split portion of the protective tube is used, the remote control gripping device can grip the end portion of the protective tube to be expanded. could not. This is because the expanded portion is closed by being sandwiched between a pair of curved arms. As a result, when attaching the end of the protective tube to the overhead electric wire, the operator has switched from the remote operation gripping device to a common operation rod with a binding hammer attached to the tip. A through hole is provided on the opposite side of the split part at the end of the protective pipe, and the protective pipe is securely supported by inserting and operating the common operation rod bind hammer in this through hole. This is because it becomes possible.

  However, for example, as shown in FIGS. 6A and 6B, every time the end of the protective tube 6 of about 3 meters is mounted in a narrow place such as the bucket 111 of the aerial work vehicle 110. It has been a very complicated task for the operator to carry out the work by moving from the remote operation gripping device 4 to the shared operation rod 11. In particular, when the number of protective tubes 6 to be installed increases, the physical burden increases and the operator's fatigue also increases. Therefore, such a change-over operation reduces the work efficiency in the overhead wire work. In addition, since it is necessary to bring both the remote operation gripping device 4 and the shared operation rod 11 to be carried into the bucket 111 of the aerial work vehicle 110, it is necessary to pay attention to safety such as prevention of dropping.

  The present invention has been made in view of the above problems, and by mounting an adapter provided with a pin rod at the tip of a remote control gripping device, the remote control gripping device can be changed to another shared control rod. It is an object of the present invention to provide an adapter that can safely and efficiently attach a protective pipe to an overhead distribution line.

  By attaching an adapter provided with a pin rod that protrudes at a predetermined angle at the tip of the arm portion of the gripping device for remote operation, the present inventors can share the other from the gripping device for remote operation during the mounting operation of the protective tube.

  Next, the usage method will be described. First, the operator grasps the head portion 53 of the locking pin 5 of the adapter 1 and pulls it up in the direction opposite to the insertion portion 22 against the bias of the elastic spring 27. As a result, the entire shaft portion 52 of the locking pin 5 enters the cylindrical portion 26, and a detachable state in which the tip of the shaft portion 52 does not protrude into the insertion portion 22 is achieved. At this time, by rotating the locking pin 5 about the shaft portion 52, the convex portion 51 provided on the shaft portion 52 comes into contact with the opening of the cylindrical portion 26 and restricts the bias of the elastic spring 27. That is, the detachable state is maintained.

  Next, after arranging the rib portion (not shown) formed at the tip of the fixed arm 42a and the slits 29, 29 formed in the adapter body 2 of the adapter 1, the tip of the fixed arm 42a is moved to the adapter. A predetermined length is pushed into the insertion portion 22 from the insertion port 21 of the main body 2. Then, the locking pin 5 is rotated around the shaft portion 52 so that the convex portion 51 fits the concave groove 28, and the above-described holding state is released. As a result, the locking pin 5 comes into contact with the surface of the fixed arm 42a in the insertion portion 22 by the urging force of the elastic spring 27, and the adapter 1 and the fixed arm 42a are engaged. In addition, when removing the adapter 1, it is good to perform operation reverse to the above.
