Description

[Detailed Description of the Invention] This invention relates to an intermediate support device for a guide rope that supports a guide rope that is tensioned along a scaffold for working at high places, a temporary bridge, etc., in the middle for the purpose of preventing falls.

Specifically, the hook that fits and moves while being guided by the guide rope (this hook is connected to the human body via the life rope) can freely pass through the intermediate support column, and the guide rope The present invention proposes an intermediate support device that does not come off the support column.

The guide rope is usually a wire rope and is fixed to the required length at a height similar to that of a handrail, with both ends sufficiently tensioned using clamps or the like.

Workers and people crossing the bridge connect the stretched guide ropes to the base via hooks to cross the bridge, and in the event of a fall, the guide ropes, hooks, and life ropes support the human body and prevent a fall. .

Therefore, it is desirable that the guide rope be stretched long enough to cover the dangerous area, but since the wire rope does not have rigidity, it bends under load, and an intermediate support column to support the middle of the guide rope becomes necessary.

The intermediate support pillar is convenient for regulating the position of the guide rope, but as mentioned above, when the hook is fitted to the guide rope and the rope is guided while passing, the hook cannot freely pass through the intermediate support pillar. This is not possible and involves the inconvenience of having to remove the hook from the guide rope, cross the intermediate support column, refit the guide rope and hook, and pass to the next intermediate support column.

For this reason, conventional devices that have been proposed are limited to those in which the intermediate support device installed on the intermediate support column and the hook fitted to the guide rope are both made of a combination of special equipment, allowing the intermediate support column to be freely moved. It made it possible for me to pass.

However, this requires an extra set of dedicated hooks, and sufficient management is required to prevent them from being mixed with non-dedicated hooks.

This idea was made taking these circumstances into consideration, and mainly uses a widely popular type of hook that is often used in similar equipment to create an intermediate support that can freely pass through the intermediate support column of the guide rope. This paper proposes a device.

FIG. 1 is a perspective view showing an example of the intermediate support device of the present invention, and is a diagram illustrating a state in which a hook fitted to a guide rope and guided is passing through the device, and FIG. Drawing of the device viewed from the side with the guide rope sectioned, No. 3
The figure is a cross-sectional view of the guide rope, showing a state in which the hook used in the device is fitted into the guide rope.

A guide rope 1 is tensioned like a handrail on a scaffold for high-altitude work, a temporary bridge, etc. (not shown), and a support column 2 is installed to stand up at a desired position between the guide rope 1 and the support column 2. The base 3 of the intermediate support device is made of a groove-like member and has a front surface 3a.

It has a bottom surface 3b and a back surface 3c.

A shaft 4 is embedded in the back surface 3c and extends toward the front surface 3a, and a retaining ring 5 is loosely fitted onto the shaft 4 in contact with the inside of the front surface 3a.

In this case, the front surface 3as of the base 3, the bottom surface 3b1, the back surface 3C1
The space surrounded by the shaft 4 and the retaining ring 5 is called a retaining opening 6 (see FIG. 2).

The guide rope 1 is inserted across the holding opening 6.

Note that 7 is a guide member that guides the position of the guide rope 1 within the holding port 6, and 2 is a guide member, although the details of the structure are omitted.
This is an attachment that adjusts the height of the support column 2 and acts as a buffer when an impact is applied.

Now, the hook 10 is fitted onto the guide rope 1.

The hook 10 is well known, but to briefly explain, it has a fishing needle-like barken part 11 at the tip, and a ring body 12 at the other end.
A life rope 13 is attached to the ring body 12 and connected to the human body via this.

The Birken part 11 is constructed such that the loop is normally closed by an opening/closing member 15 to prevent the fitted object from falling out of the loop 14.

When the hook 10 is guided by the guide rope 1 and reaches the support column 2, the hook 10 hits the end 3a of the front surface 3a of the base 3 of the intermediate support device and one of the petal-like holding parts 5 of the holding ring 5. match.

Since both the end portion 3a and the holding portion 5 have a tapered shape, the abutting hook 10 can be smoothly introduced into the holding port 6 (
(See FIG. 1; in this figure, the hook 10 is assumed to be moving from the left to the right).

In this case, since the retaining ring 5 is loosely fitted to the shaft 4, it can freely rotate counterclockwise and connect the two adjacent retaining parts 5.
It is passed through with the hook 10 inserted between them.

Therefore, the hook 10 passes through the support column 2 while being fitted into the guide rope 1, and the guide rope 1 remains inserted into the holding hole 6 and does not come off from there.

On the return trip as well, the hook 10 passes through the intermediate support device from the right to the left in FIG. 1 in the same manner as described above.

Note that the guide rope 1 is inserted into the holding hole 6 by the shaft 4.
This is done by removing the locking nut 4 and removing the retaining ring 5 loosely fitted onto the shaft 4.

According to the present invention, as described above, intermediate support of the guide rope 1 can be performed using a simple member, and moreover, the guide rope 1 can be supported intermediately by using a simple member.
The types of hooks 10 to be fitted are the two adjacent ones of the retaining ring 5.
As long as the guide rope 1 fits between the fan-shaped spaces formed by the individual holding portions 5, it is possible to freely pass through the intermediate support device with the guide rope 1 fitted between the loops 14.

In the embodiment of the present invention, an example was shown in which the guide rope was tensioned horizontally and a hook was fitted to it, but as an application, for example, the guide rope may be tensioned vertically near a lifting device, and It goes without saying that it can also be used as an intermediate support device for a guide rope in a fall prevention device, which is fitted with a safety device that grasps the guide rope and fixes it in that position in the event of a fall.
