2. Description of the Related Art Conventionally, when ascending and descending telephone poles, towers, etc.,
The rope on the safety belt on the pole attached to the waist of the high-altitude worker is wrapped around the utility pole and the main pole of the tower (U-shaped state). At places where there are obstacles that cannot pass, hook the hook at the other end of the rope (auxiliary hook) over the obstacle,
The hook (real hook) that was initially hooked is removed and the driver passes through that position. After passing through the hook, the hook is replaced with the real hook again and then goes up and down. It was unlocked, and there was a possibility that a crash disaster would cause loss of human life.

As described above, conventionally,
There was a drawback that a non-locked state occurred due to human error. The reason is that accidents caused by mistakes are unavoidable in conventional pole safety belts unless they are used properly. In a conventional D-ring attached to a safety belt, hooks of any shape can be freely removed, and this has caused a non-locked state.

SUMMARY OF THE INVENTION Therefore, in order to eliminate the unlocking state when using the safety belt on a pole, the present application removes the other hook unless one hook is completely connected to the safety belt. The present invention provides a coupling device that cannot perform such operations, and the coupling device and the corresponding hook enable a more secure lifting method. Specifically, the coupling device 2

The hooks must always fit in the locking grooves A, and the hooks fitted in the locking grooves A move together with the rotary plate 50, reach the holding grooves B, and enter the locked state. Become. To remove the hook locked earlier, if another hook is fitted in the locking groove A as well, it moves together with the rotary plate 50 and reaches the holding groove B to be in a locked state.
The hook located in the holding groove B reaches the release groove C and can be released from the ring.

An example of the method of elevating and lowering the present application will be described with reference to the drawings. First, as shown in FIG. 1, a safety belt is attached to the waist of an operator, the hook 7 is wrapped around a utility pole, and then is engaged with the coupling device 2. The length of the rope 6 is adjusted by the rope expansion / contraction adjuster 9, and the pole is raised while avoiding the step bolt in the U-shape state, and goes down to the telephone line in the middle of the telephone pole. Next, as shown in FIG.
Remove the auxiliary hook 8 held on the D-ring of the square ring, and hang it on the telephone line. And the auxiliary hook as shown in FIG.
8 is lifted, locked to the coupling device 2, moved to the center, and the hook 7 is removed. And it goes up to the pole top. In FIG. 2, the auxiliary hook 8 may not be turned over the telephone line, but may be turned down below the telephone line, and the detached hook 7 may be turned again over the telephone line. The adjuster 9 is equipped with a function to prevent a reverse fall, which holds the rope and stops even if a fall occurs when the auxiliary hook is locked. As a method of performing this, it is necessary to increase the time required for one-time removal compared with the above method, but this is a good use method.

When a hook is attached to and detached from the coupling device 2 used in the present application, as shown in FIG. 9, first, when the main hook 7 is locked in the locking groove A, the tip of the hook 7 is locked by the lock plate 60.
Is pressed downward against the spring 62, the stopper 61 locked in the notch groove 51 of the rotating plate 50 is released, and the rotating plate 50
Is rotated to reach the position of the holding groove B (FIG. 10), and at the same time, the lock plate 60 is pushed up by the elastic force of the spring 62, and the stopper 61 is fitted into the next notch groove 51 to move the hook 7 to the left and right. To lock. The hook 7 once locked in the holding groove B does not come off in any state. This is a structure in which the hook locking portion 22 on the outer periphery of the holding groove B is bulged and locked by providing the hook holding portion 25, and the size of the hook portion of the hook 7 is large so that the cap rotates and the hook port cannot be released. And Therefore, if a worker works at a high place in this state, the worker cannot accidentally remove the hook, so that a crash does not occur. Next, when the main hook 7 engaged with the holding groove B is removed, the auxiliary hook 8 is locked in the locking groove A in the same manner as described above, and the lock plate 60 is pressed downward to lock the main hook 7. The hooks 7 engaged in the holding grooves B and the auxiliary hooks 8 engaged in the engaging grooves A are simultaneously engaged with the hook engaging portions 22 of the coupling ring 23 in the same manner as described above. When the hook 7 is moved in the clockwise direction, the hook 7 reaches the release groove C, the auxiliary hook 8 reaches the holding groove B, and at the same time, the lock plate 60 is pushed up by the elastic force of the spring 62 so that the stopper 61 is inserted into the notch groove 51. Fits and locks hook movement. In this case, the auxiliary hook 8 fitted in the holding groove B cannot be removed from the coupling ring 23 as described above, but the main hook 7 located in the release groove C can be removed from the coupling ring 23. it can. (FIG. 11) As described above, the two hooks are locked in the locking groove A, and are sequentially moved in the direction of the holding groove B and the release groove C to alternately remove the two hooks. Since the two hooks are locked in the state of being locked to the connecting ring body 23, the two hooks are not disengaged at the same time due to an erroneous operation or an illusion of the worker and become unlocked, and the body of the worker during any work or movement. Is always a rope
Since it is connected to a telephone pole and a steel tower via 6, it is safe without a crash.

According to the present invention, a fall-free ascent / descent method is possible by using a coupling device having a simple structure. This is an interlock structure in which one hook of the coupling device cannot be released unless the other hook is hooked, and one of the hooks is constantly locked to the coupling device so that the illusion and psychological sensation of the worker can be maintained. This is due to the elimination of the unlocked state due to a mistake, and no special training is required, and great safety can be obtained by preparing a coupling device having a simple structure.
