JP3102282U - Safety belt wire connecting member - Google Patents

Abstract

An object of the present invention is to provide a member for connecting a safety belt wire for securing the safety of workers at a high place in a building such as a factory where the degree of freedom of a scaffold is small.
A safety-band wire connecting member used when a safety-band hook (7) is anchored to a wire and moved in an aerial workplace where a safety-band wire is stretched between columns. It is characterized by having a bypass 5 branched from a wire for bypassing between the wires, and a hook pad 6 for opening and closing the opening / closing lever 8 of the safety belt hook at a branch point of the wire and the bypass.

Description

  The present invention relates to a member for connecting a safety belt wire for a worker to walk safely in high places such as a factory.

  As a well-known example of this type of work at a high place on a construction site, Patent Document 1 discloses an inner space through which a hook of a safety belt can be penetrated by using a metal or synthetic resin having a set strength as a material, and an end portion is provided. A quasi-annular body having a parallel width of a set length through a gap having a gap width that allows the safety band connected to the hook to slide through with the sides at both ends facing each other. A section is provided to form a safety cable anchoring portion in a quasi-spiral form of one or more and less than double, and a connecting piece that projects from a part of the outer periphery of the safety cable anchoring portion on a diametrically extended line is formed in abutting contact, There is disclosed a support and anchoring device for a safety rope which is installed around a construction site and has a mounting member such as a steel pipe clamp or a fastener or a general connector attached to a tip of the connection piece.

  Patent Document 2 discloses a jig for restricting the position of the master rope, which has a shape surrounding the master rope, and whose front and rear ends are defined in a direction along the master rope. There is disclosed a master rope controlling jig which is configured so as to be present at intervals and is formed in a substantially coil shape.

Japanese Patent No. 2729365 JP-A-6-74157

  In a high place work in a building such as a factory, unlike the work at the construction site in the known example, the degree of freedom of the scaffold at the time of the work is small. That is, in high-altitude work in a building such as a factory, building structures such as pillars and beams are restricted, and scaffolds on which workers move are limited. Further, at present, it is often the case that a wire for a safety belt can be installed only in a limited place.

  In particular, in the garter section of a factory overhead crane, the space is limited, the scaffold is narrow, and a wire for the safety belt can be installed only between the columns. For this reason, when the maintenance and inspection worker moves the safety belt hook while anchoring it to the wire, the hook is once removed from the wire at the place where the pillar is, and the hook is stretched around the pillar and stretched to the opposite side of the pillar. Need to be re-tethered to the broken wire. This means that the safety belt does not function when going around the pillar, and there is a problem that it is very dangerous.

  An object of the present invention is to provide a member for connecting a safety belt wire for avoiding the above-mentioned danger.

  A safety band wire connecting member used when a safety band hook is anchored to a wire and moved in an aerial workplace where a safety band wire is stretched between columns, and bypasses between the wires. For this purpose, a bypass branched from the wire and a hook pad for opening the opening and closing lever of the safety belt hook at the branch point of the wire and the bypass are provided.

  By using the safety belt wire connecting member of the present invention, it is possible to install a safety belt wire for wrapping around a pillar at a high place such as a factory and to move the safety belt hook without removing the wire from the wire. be able to.

  FIG. 1 shows an embodiment of a member for connecting a safety belt wire according to the present invention, and is a schematic view of an aerial work site of a building in which the member for connecting a safety belt wire is installed.

  In FIG. 1, the safety belt wire connecting member according to the present invention includes a bypass 5 branched from the wires 4a and 4b to detour between the wires, and opening and closing of a safety belt hook 7 at a branch point of the wires 4a, 4b and the bypass 5. And a hook pad 6 for contacting and opening the lever 8. In an aerial workplace composed of the pillar 1 and the scaffold 3, the safety belt wires 4a and 4b are fixed and stretched on both side surfaces of the pillar 1. The safety band wires 4a and 4b are provided with a bypass 5 made of a steel rod or the like for bypassing the column 1. Further, at a branch point between the safety band wires 4a and 4b and the bypass 5, an opening / closing lever 8 of a safety band hook 7 is provided. A hook metal plate 6 made of a steel plate or the like is provided by welding or the like. The safety belt includes a safety belt hook 7, an opening / closing lever 8, and a safety belt main body 9. The opening / closing lever 8 is biased toward the closed position by a spring (not shown). Further, the safety belt main body 9 is fixed to the trunk of an operator (not shown).

  In FIG. 1, when the worker moves the safety band wire 4a around the pillar 1 by anchoring the hook 7 to the safety band wire 4b, when the hook 7 branches from the wire 4b to the bypass 5, the hook opening / closing lever is opened. The opening / closing lever 8 is opened when the hook 8 contacts the hook pad 6. The hook 7 is pulled in the moving direction of the worker with the opening / closing lever 8 opened, and moves to the bypass 5. Upon completion of the movement, the opening / closing lever 8 of the hook 7 is quickly closed by the spring, and the hook 7 moves smoothly from the wire 4b to the bypass 5.

  Also, when moving from the bypass 5 to the other safety band wire 4a, the hook 7 can be smoothly moved to 4a by the same mechanism as described above.

  When the safety belt wire connecting member was installed on a garter maintenance and inspection scaffold of an overhead crane installed in a factory building and actually used, the safety belt hook was securely anchored to the safety belt wire and bypass. As a result, the safety of the workers has been significantly improved.

  According to the present invention, the safety belt hook can be securely tied to the safety belt wire and the bypass even when working at heights in a building such as a factory where the building structure such as columns and beams are regulated, so that the safety of workers is ensured. Can be obtained.

FIG. 4 is a view showing an embodiment of the safety belt wire connecting member of the present invention.
