Rope guide apparatus for proventing aerial worker fall

The present invention relates to a rope guide device for high-altitude work for preventing workers from falling, and more particularly, when performing high-altitude work using a rope, such as cleaning an outer wall, reduces the frictional force generated while in contact with the rope and increases the durability of the rope It relates to a rope guide device for high-altitude work for preventing a fall of a worker, which can prevent sudden breakage of the rope to prevent injury and death due to a fall.

In general, safety equipment for high-altitude work performs external wall work by stably fixing or seating the body on a belt or seat plate fixed by a single rope or a pair of safety ropes without relying on a machine such as a crane in a high-rise building or a specific structure. It's a device that can do that.

Such a seat belt or safety seat must be able to mount the buttocks so that the operator can comfortably work at high altitude for a certain period of time, the arms and legs must be able to move freely, and maintain a stable posture even in strong winds from high places. it should be possible to do

However, various conventional seat belts strongly press between the shoulder, leg, or crotch of the worker, and numbness may occur during long-time work. There was a problem that safety accidents frequently occurred because it was difficult to maintain balance. In addition, the work was carried out by fixing the rope fixed to the roof as shown in Fig. 1 (b) without a stabilizer.

Among the related prior arts for solving the above problems, Republic of Korea Utility Model Registration No. 20-0471729 (registration date: 2014.03.05) discloses a technology related to "industrial swing seat belt".

The prior art described in Republic of Korea Utility Model No. 20-0471729 is provided with a shoulder belt positioned on the shoulder from the front of the user's upper body and a backrest belt seated on the worker's back, and is fastened horizontally in front of the chest and a safety ring installed on the chest belt and the backrest belt, wherein the backrest belt connects the shoulder belt horizontally and is spaced apart from each other in parallel with a pair of horizontal support members and a pair of horizontal support members vertically It consists of a single vertical support member that connects to each other with a do.

The prior art as described above has the advantage that safety can be increased and a comfortable fit can be provided by connecting the straps of a simple configuration horizontally and vertically to improve the support force of the safety ring mounted on the backrest belt.

However, even if the comfortable fit and safety are increased as described above, if the frictional force between the rope and the building occurring on the upper side of the building cannot be reduced, the durability of the rope is reduced due to the increase in frictional force, and the rope is cut, resulting in a fall accident of the worker. Or, it is difficult to prevent disasters such as fatal accidents.

2 to 6, the rope guide device for high-altitude work for preventing a worker from falling according to an embodiment of the present invention extends downward from the roof of the building and connects the rope to the seat plate supporting the worker in a stable state It is maintained to guide the movement of the rope to prevent the worker from falling as well as to reduce the abrasion of the rope, and includes a wear prevention guide 110 and a fall prevention part 120 .

The anti-wear guide 110 is disposed on the roof of the building, and a bidirectional through-hole is formed to extend downward to prevent abrasion of the rope, and the horizontal extension 111 and the vertical extension 112 are provided. and a support pad 113 .

The horizontal extension portion 111 is to guide the insertion in one direction of the rope (R), and extends from the roof toward the front of the building in the horizontal direction. The horizontal extension portion 111 is formed to have a relatively large diameter for the smooth inflow of the rope, and is curvature formed in the front of the rope flowing in. Through this, it is possible to increase the durability of the rope (R) by reducing the frictional force generated with the rope (R) at the entrance side to prevent the breaking phenomenon to prevent the rope (R) from being damaged.

The vertical extension 112 is bent downwardly from the end of the horizontal extension 111 and extends in the vertical downward direction of the building. The vertical extension part 112 is formed integrally with the horizontal extension part 111, and preferably, when extending downward, the tube diameter is formed to expand in an elliptical trumpet shape. And, the vertical extension portion 112 can reduce friction with the rope by being curvature-formed to have a relatively large diameter at the end.

When a worker hanging from a rope (R) extending downward from the roof moves left and right, it can naturally move left and right along the vertical extension part 112 formed in the shape of an oval trumpet, so the end of the vertical extension part 112 and The contact surface of the abutting rope (R) is naturally formed to prevent the rope (R) from being abraded. Therefore, by increasing the durability of the rope (R), it is possible to prevent a safety accident such as a fall of the operator due to the breakage of the rope (R) during high-place work.

The support pad 113 is formed in an 'L' shape with an approximate cross-sectional shape to cover the upper end of the building, and the horizontal extension part 111 is disposed thereon to support the wear prevention guide 110 . do. The support pad 113 may be formed of a material with a cushion, and is compressed to a predetermined degree through the pressure of the abrasion prevention guide 110 while increasing the frictional force with the abrasion prevention guide 110 while increasing the wear prevention guide 110 . ) and at the same time prevent damage to the top of the building.

The fall prevention part 120 is formed with a through hole in one direction so as to be connected to the rope (R) extending through the wear prevention guide part (110). The fall prevention unit 120 may be integrally formed in a pipe shape, or may be formed in a semicircular shape cut so that a pair can be coupled to each other to form a pipe shape. In this way, when formed in a semicircular incised shape, it is possible to more easily form the surface treatment part 121 to be described later along the inner circumferential surface. The fall prevention unit 120 may be formed of a metal material or high-strength plastic, but the material is not limited thereto.

A belt ring 124 for fixing the safety belt of the operator to the outer peripheral surface of the fall prevention unit 120 is provided. The belt loop part 124 is coupled to the outside of the fall prevention part 120 and serves to fix the hook of the safety belt worn by the operator. At this time, the belt fixing part 124 may be formed in an approximately closed ring shape, and the diameter of the ring therein may be formed around 20 mm, but the size of the diameter is not limited thereto.

When describing the fall prevention unit 120 in more detail, the fall prevention unit 120 may be formed in a tapered shape in which the inner diameter is narrowed from the upper side to the lower side. When formed in such a tapered shape, the movement of the rope (R) moving in the inside can be reduced to minimize the shaking, so that the operator can more comfortably respond to the movement of the rope (R).

And, the inner peripheral surface of the fall prevention unit 120 may be provided with a surface treatment unit 121 to form a rubber material or roughness to increase the frictional force with the rope. The surface treatment part 121 is inserted into the fall prevention part 120 and the rope (R) which is disposed through the fall prevention part 120 is able to maintain a firmly fixed state on the inner circumferential surface.

At this time, the fall prevention unit 120 has an upper guide 122 and a lower guide ( 123) may be formed. The upper guide 122 and the lower guide 123 naturally induce the fall prevention part 120 and the rope (R) to come into contact with each other, thereby preventing the durability of the rope (R) from being deteriorated due to friction. It is possible to prevent safety accidents such as falling accidents by preventing problems such as breaking (R).

In addition, the upper end of the fall prevention unit 120 may be formed obliquely from the outside to the inside direction without being formed at the same height on the inside and outside. At this time, the range of the angle (θ) may be formed by cutting in a range of 0 to 75 degrees from the outside of the upper end of the fall prevention unit 120 in the inward direction (counterclockwise). In this way, when the upper end is formed by being cut obliquely from the upper side to the lower side, when a fall state occurs due to the operator's mistake or unexpected wind speed, the fall prevention unit 120 by the weight of the operator as shown in FIG. 3 . The rope (R) is bent while rotating at 90 ~ 120 °, so that it is possible to prevent the operator from falling by the frictional force of the fall prevention unit 120 and the rope (R).

The rope guide mechanism for high-altitude work for reducing the wear of the rope and preventing the worker from falling according to the present invention reduces the frictional force generated while in contact with the rope and increases the durability of the rope when performing high-place work using the rope, such as cleaning the outer wall By preventing sudden breakage of the rope, it is possible to prevent injuries and deaths due to falling. In addition, by providing a stable movement when the rope moves left and right, it is possible to improve the efficiency of work by providing a psychological stability to the worker sitting on the work plate.
