動させるものである。(Embodiment) As one embodiment of the present invention, an aluminum extruded profile having a concave busbar rope slide holding groove 1 at the center in the width direction is cut to a predetermined length, and one of the busbar rope slide holding grooves 1 is cut. The hinge part 2 is formed by notching two sides. Engaging pins 3 are provided upright on both ends of the joint surface on the other side, and a safety pin hole 5 is inserted through the center of the engaging pin 3.
And the safety pin 4 is inserted. With respect to the slide holding portion 6 having the above-described structure, a hinge portion 7 which is also made of aluminum extruded and protrudes at two corresponding positions, and an engagement pin receiving hole having a substantially dull shape
8, a safety pin receiving hole 9 is provided, and a stop claw hole 26 is provided between the hinge portion 7 and the engagement pin receiving hole 8 and the safety pin receiving hole 9, and the stop claw hole on the other side is provided.
26. A shaft stop wall 20 is provided upright on both sides, and a shaft grip 14 is provided on the shaft stop wall 20 and a rope gripping rod 12 is provided. The rope gripping rod 12 is the shaft stop wall mentioned above.
A rope coupling ring (10) protruding from (20) is used as one end, and the other end is provided with a rope stop hook (11) housed in a stop hook hole (26). Also, the shaft stop wall 20
A spring 13 is urged to the shaft stopper 14 so that the rope stop claw 11 is rotated on the busbar rope slide holding groove 1 of the corresponding slide holding portion 6 at all times.

阻止するものである。The lock body 15 is provided with an elongated hole 19 for inserting the shaft 16 in the center, and a contact cutout portion 21 provided on the shaft stop wall 20 of the rope gripping rod holding body 17.
And a slide piece 23 that abuts the shaft stopper wall 20 at both ends, and a rear end portion is provided with a pressing portion 24 formed by cutting the slide piece 23 into a tapered side section, A spring 25 is arranged between the shaft 16 and the tip of the long hole. A child rope 28 having a hook 27 attached to the tip thereof is attached to the rope coupling ring 10 to be used for raising and lowering. In the invention of the present invention having the above-mentioned configuration, in use, first, the screwing of the safety pin 4 is released, and the hinge portion 2 of the slide holding portion 6 and the rope gripping rod holding body 16,
By sliding 7 against each other against the spring 18, the engagement pin 3 is moved from the small hole 81 of the engagement pin receiving hole 8 to the large hole 82, and pulled out from the large hole 82. Therefore, by accommodating the busbar rope in the busbar rope slide holding groove 1 and closing the busbar rope by the reverse operation, the rope retaining pawl of the rope gripping rod always presses the busbar rope. The hook 27 of the child rope 28 is hooked on the ring of the safety belt to perform the ascending pillar, but the safety device of the present invention is a form that follows the operator from its weight and the length of the child rope 28, Therefore, the rope clasp of the rope gripping rod 11
Is rotating in the direction away from the busbar rope,
Should the operator step off the foot, the rope gripping rod 12 rotates downward, and the rope stop claw presses the busbar rope to prevent the fall.

である。Further, when working at a fixed position during the ascending pillar, by pressing the pressing portion 24 of the lock body 15, the contact portion 22 floats up, disengages from the contact cutout portion 21, and due to the elasticity of the spring 25,
Sliding on the shaft stop wall 20, the contact portion 22 contacts the rope gripping rod 12, and the rope stop claw 11 presses the busbar rope.
At that position, the worker's fall is prevented. When the work at the fixed position is completed, the lock body 15 is again resisted against the spring 25.
Slide and lock the contact portion 22 in the contact cutout portion 21,
The rope gripping rod 12 is allowed to freely rotate and the ascending pillar is started.
