JPH08332241A - Method of ascending and descending pole without falling - Google Patents

Abstract

PURPOSE: To eliminate fall disaster at the time of ascent and descent of a distribution pole. CONSTITUTION: This method is one for a worker to ascend and descend after interposing a winding type of anchor rope B between a hooking member C and the worker on the ground, by coupling a hook F of the winding type of anchor rope B to a safety belt that the worker is wearing, and hooking a hook E for hooking of the winding type of anchor rope B to the hooking means C such as an arm, etc., provided in the specified position of a distribution pole P by elongating a telescopic rod, by the operation from on the ground while pulling out a belt of the winding type of anchor rope B. Hereby, it is coupled from the beginning by the winding type of anchor rope, and the worker can ascend and descend without resetting the rope of the safety band, so he can ascend and descend the pole without anxiety without getting in trunk rope free condition. If he should fall, slipping his hand or foot, a centrifugal claw of a winder works quickly and, and checks feeding the rope and prevents the fall.

And the hanging hook E is lifted, and the hanging member C is installed on the armrest in FIG. 2 and in the middle of the utility pole in FIG.
Installation work is completed. After that, the expansion rod D is contracted and stored. Then, as shown in Fig. 1, the pillar is going up, but even if there is a signboard or street light at this time, the pillar can be lifted up without changing the rope, and it will not be in the state of no rope and it will reach the working position. it can. The worker who has climbed to the work position works by turning the main rope of the safety belt attached to his waist around the utility pole. After the work is completed, the worker who removes the rope, descends the pillar, and descends to the ground, extends the expansion rod D, and extends the expansion rod D to the hanging ring portion 5 of the hook H for hooking.
Hook the tip of the hook and push it up to rotate the open / close plate 3 of the hook H to open the hook space K.
Further, by raising the expansion rod D, it can be detached from the arm member and the hook member C. Then, the expansion rod D is sequentially contracted and collected.

足にからむようなことはない。The hoisting and lowering method of the present invention improves the handleability due to the downsizing and weight saving of the above-mentioned equipment, and can be easily hooked at a high place from the ground through the elastic rod. The state is reliable, and in the hooked state, the belt-shaped rope of the winding type mooring rope connected to the hook for hooking freely expands and contracts, so that it can be easily moved up and down to the utility pole without being restrained. In addition, even if the limbs slip and fall during lifting, the centrifugal claws of the winder work quickly to prevent the belt-shaped rope from being fed out, and the fall distance is much shorter than with conventional products, and it is received by the operator's body. The impact load is small, and it is possible to safely prevent a fall and eliminate a fall disaster. Further, the belt type rope of the take-up type mooring rope is taken up by the urging force of the vortex winding spring and follows the upward and downward movement of the operator and does not get entangled in the limbs of the operator.
