Description

D-type ring of the pillar safety belt and pillar safety belt using the same}

The present invention relates to a D-shaped safety belt and a pillar-shaped safety belt using the same. Specifically, the present invention relates to a D-shaped ring for hanging a safety rope to prevent falls so that workers can work while ascending and lowering on a column-shaped structure such as a telephone pole, and a D-shaped ring for hanging a safety rope to prevent falls. This is about a residential safety belt using this.

A pole-shaped safety belt can be worn by workers to climb pillar-shaped structures such as telephone poles and perform electrical work, communication work, or other work required at high places. It maintains a stable posture while working and prevents falls. This is a device that can prevent it.

Figure 1 is a photograph showing a conventional conventional pole safety belt, and Figure 2 is a perspective view showing the D-shaped ring used in Figure 1.

A typical column safety belt includes a waist protector (10) that directly surrounds the waist and is closely attached and is provided with a cushion to protect the waist, a rope support (20) coupled and fixed to the outer surface of the waist protector (10), and the rope. A fixing ring 30 coupled to one end of the support 20, a D-shaped ring 40 coupled to the other end of the rope support 20, and a belt shape are provided with a buckle 51 at one end. A seat belt (50) worn around the waist around the outside of the waist protector (10) and the rope support (20), and a first tie ring (61) made in the shape of a rope and one end of which can be hung on the fixing ring (30). It may be configured to include a safety rope 60 coupled to the other end and a hook-shaped second binding ring 62 that can be hung on the D-shaped ring 40. At this time, the first binding ring 61 is always maintained on the fixing ring 30, and the second binding ring 62 can be fastened or released.

The worker wears the seat belt 50 on the waist, wraps the outside of the telephone pole with the safety rope 60, and then binds the second binding ring 62 to the D-shaped ring 40 to secure the safety rope ( 60) can support the worker's body weight.

Here, the D-shaped ring 40 may be composed of a ring portion 41 formed in the shape of the alphabet D as shown in FIG. 2 and a support portion 42 formed in a beam shape on one side of the ring portion 41. . At this time, the rope support 20 surrounds the support portion 42 and the D-shaped ring 40 is coupled to the rope support.

However, due to this structure, a problem occurs in which the D-shaped ring 40 rotates at the end of the rope support 20. In other words, the D-shaped ring 40 rotates around the support portion 42 of the D-shaped ring 40 so that the ring portion 41 is tilted back to the rope support 20.

Therefore, when the worker actually tries to fasten the second binding ring 62 to the D-shaped ring 40, it is very inconvenient and a risk of safety accident occurs.

Additionally, when describing the present invention, if it is determined that a detailed description of related known technology may unnecessarily obscure the gist of the present invention, the detailed description may be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 3 is a photograph showing a D-shaped ring of a pole safety belt according to an embodiment of the present invention, and Figure 4 shows a cross-sectional view of the present invention shown in Figure 3.

Referring to Figure 3, the D-shaped ring of the pole safety belt according to the present invention largely includes a ring portion 41, a rotation prevention portion 43, a support portion 42, a separation prevention portion 44, and a first slot ( 45) and a second slot 46.

First, the ring portion 41 will be described.

The ring portion 41 is approximately in the shape of the alphabet D so as to be able to hang the second tie ring (to be described later) attached to the safety rope 60 of the pole safety belt and is made of steel with high strength.

And the rotation prevention portion 43 is formed at one end of the ring portion 41 across the ring portion 41 and may be formed in a beam or rod shape.

Additionally, the rotation prevention part 43 may be made of the same material as the ring part 41.

In addition, the support part 42 located inside the rotation prevention part 43 is formed on one side of the ring part 41.

The support portion 42 may also be formed in a beam or rod shape similar to the rotation prevention portion 43 and may be made of steel.

At this time, the support part 42 is connected to the end of the rope support 20 and becomes the rotation center of the ring part 41.

Here, the rotation prevention part 43 and the support part 42 are spaced apart from each other and a first slot 45 is formed therebetween. The first slot 45 is designed to have a width greater than the thickness of the rope support 20 and a length longer than the width of the rope support 20 so that the rope support 20 can pass through it.

Meanwhile, the separation prevention part 44 is formed on one side of the support part 42 to be spaced apart from each other. Accordingly, a second slot 46 is formed between the separation prevention part 44 and the support part 42.

The second slot 46 is also designed to have a width greater than the thickness of the rope support 20 and a length longer than the width of the rope support 20 so that the rope support 20 can pass through it.

Similarly, the separation prevention portion 44 may also have a beam or rod shape and may be made of steel.

As shown in Figure 4, in the present invention, the rope support 20 passes through the first slot 45, surrounds the support part 42, and then passes through the second slot 46.

That is, the rope support 20 is folded in half and overlapped, coupled and fixed to the waist protector 10 of the pole safety belt, and is caught while accommodating the support part 42 inside the folded portion, and the support part 42 It acts like a hinge. In other words, the D-shaped ring 40 can swing around the support portion 42 during work.

What is important is that the rotation prevention portion 43 can limit the rotation of the D-shaped ring 40. In other words, even if the ring portion 41 rotates in one direction about the support portion 42, the end of the rotation prevention portion 43 is caught on the outer surface of the rope support 20, thereby forming the D-shaped ring 40. Stop rotating it. Of course, rotating in the opposite direction is not a big problem.

Therefore, since the D-shaped ring 40 is not tilted back, the worker can immediately hang the second binding ring without having to return the bent ring portion 41 to its original position.

In addition, the separation prevention portion 44 blocks the folded portion of the rope support 20 from moving toward the ring portion 41, so that the rope support 20 is restrained within the second slot 46. do.

Preferably, the ring portion 41 is formed to be inclined at a certain angle at the point of the separation prevention portion 44 to prevent the ring portion 41 from being adjacent to the waist protector 10.

That is, the ring portion 41 is maintained at a certain distance from the waist protector 10, so that the second tie ring can be easily hung.

The inclination angle of the ring portion 41 is preferably 10 to 30°. If it is less than 10°, the ring portion 41 is too close to the waist protector 10 and thus becomes meaningless, and if it is larger than 30°, the ring portion 41 is too wide and the rotation prevention portion 43 Reduces the function of

In summary, the ring portion 41 can maintain an optimal position for hanging the second binding ring due to the inclination angle of the rotation prevention portion 43 and the ring portion 41. And when the safety rope (60) is hung around the telephone pole, the opening angle of the safety rope (60) and the inclination angle of the hook (41) match, so that the worker hangs the second tie ring on the hook (41). Not only is it easy, but it also allows you to maintain a stable posture.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 5. Figure 5 is a photograph showing a pole safety belt using a D-shaped ring according to another embodiment of the present invention.

Another embodiment of the present invention relates to a pillar safety belt using the above-described D-shaped ring of the pillar safety belt, including a waist protector (10), a rope supporter (20), a fixing ring (30), a D-shaped ring (40), and a seat belt. (50) and may be composed of a safety rope (60).

First, the waist protector 10 is shaped like a wide belt and directly wraps around the worker's waist. Therefore, the waist protector 10 may be made of fabric and may be provided with a cushioning material on the inside.

The rope support 20 is coupled to and fixed to the outer surface of the waist protector 10. The rope support 20 supports the tensile force applied to the safety rope 60, which will be described later.

To this end, the rope support 20 must be strongly coupled so that it does not become separated or separated from the waist protector 10 even under strong external force.

Preferably, the rope support 20 is made in the shape of a strip, and can be coupled to the waist protector 10 in a circular shape by folding both ends and stacking the central part in two layers. The folded ends can form a ring-like shape.

The fixing ring 30 is coupled to one end of the rope support 20.

The fixing ring 30 can hang the first binding ring 61 of the safety rope 60, which will be described later.

Here, since the first binding ring 61 is always maintained in a fastened state, the fixing ring 30 may have various shapes.

And a D-shaped ring 40 is coupled to the other end of the rope support 20.

Since the D-shaped ring 40 is the same as described above, detailed description is omitted.

Next, the seat belt 50 allows the worker to wear the present invention on the waist, and is made in the shape of a belt and is equipped with a buckle 51 at one end that can be locked and unlocked.

And the seat belt 50 is attached around the outside of the waist protector 10 and the rope support 20. For this purpose, the waist protector 10 is provided with one or more mounting straps 11 at regular intervals.

Therefore, the seat belt 50 can be mounted on the waist protector 10 while passing through the mounting strap 11, and the worker can wear the seat belt 50 on the waist.

Next, the safety rope 60 surrounds the telephone pole and one end is tied to the fixing ring 30, and the other end is tied to the D-shaped ring 40 so that the worker can secure the body on the utility pole.

For this purpose, a first binding ring 61 is coupled to one end of the safety rope 60, and a second binding ring 62 is coupled to the other end.

The first tie ring 61 is always coupled to the safety rope 60, and the second tie ring 62 has a structure that can be tied to or released from the D-shaped ring 40, as described above.

Meanwhile, referring to FIG. 4, a friction prevention member 70 may be further inserted between the support portion 42 and the rope support 20.

The friction prevention member 70 may be in the shape of a pipe made of a soft resin material to minimize friction that occurs between the support part 42 and the rope support 20 when the ring part 41 swings.

Below, the operating process of the present invention will be briefly described with reference to FIG. 6. Figure 6 shows a state diagram of use of the present invention shown in Figure 5.

The worker puts the seat belt 50 around his waist, fastens the buckle 51, adjusts it to fit his body, and wears it.

Additionally, a separate auxiliary rope (not shown) can be tied to a position above the waist to prevent falling from the working position by climbing onto the telephone pole.

Next, untie the second binding ring 62 bound to the D-shaped ring 40, wrap it around the electric pole, and then fasten the second binding ring 62 to the D-shaped ring 40 again.

Here, as shown in FIG. 6(a), the D-shaped ring 40 is not tilted back but remains spread forward at a certain angle, making it very easy to bind the second binding ring 62.

Even if it is tilted back by hand as shown in Figure 6(b), it can be prevented from opening beyond a certain angle by the rotation prevention part 43.

When the work is completed, unfasten the second binding ring 62 and release the auxiliary rope, then come down from the electric pole and unfasten the seat belt 50.
