Safety rope lowerer with double brakes {The immediacy rope drop which affixes duplex brake equipment}

The present invention relates to a safety rope lowering device equipped with a double brake device, and more particularly, a lowering device formed by combining an operating member acting as a brake on an upper portion of a fixing member having a locking device on a rectangular tape-type rope. It is possible to control descent speed and stop descent during life-saving, construction site, building exterior wall cleaning and work in high-rise building, and double brake is installed for safe and rapid descent and work. And a safety rope lowering device equipped with a dual brake device that is light in weight and easy to carry and use.

In general, when high-rise buildings such as apartments, hotels and neighboring facilities occur, such as a fire, work is performed in the air during life-saving situations that quickly evacuate people on high floors to a safe ground or when cleaning the exterior walls of construction sites or high-rise buildings. If you do, you will descend the ground or work in the air with a safety rope fixed to the building.

However, in this case, the user can not control the descent speed, and the rope must be lowered and evacuated without any additional safety equipment, so there is a risk of falling, which adds to the emotional and psychological anxiety of the user. The circular safety rope made is tough and hard, but it is hard to hold and descend by hand, and the user hangs on the safety rope because the circular surface collides with the building, and the risk of falling increases.

In particular, the elderly and young children are impossible to use, and with the inconvenience that safety personnel must hold the rope ends on the ground, several people can not descend together at the same time to evacuate quickly.

In addition, the safety rope used to clean the outer wall of a construction site or a high-rise building is equipped with a pulley installed on the roof of the building to provide a space for a worker to sit or stand at one end and to tie the safety rope at the other end to work in the air. After doing so, the safety rope is lowered to the proper working position again to fix it, but the worker has to solve the problem because it is difficult to fit the proper position for the work because it is necessary to loosen and bundle the safety rope.

Therefore, the present invention has been made in order to solve the above-mentioned closed end, by mounting a descender formed by combining the operation member acting the brake on the upper portion of the fixing member formed a locking device to a square tape rope, volume and weight Its small size makes it easy to carry and use, and it is possible to adjust the descent speed and stop the descent when cleaning people's lives in a high-rise building, construction site or building's exterior wall, and the double brakes of the locking member and operating member are damaged or broken. The objective is to provide a safety rope lowering device equipped with a double brake that can safely and quickly lower and work even in the city.

When the hinge coupling portion 111 of the fixing member 110 and the coupling portion 121 of the operating member 120 are hinged, the operating member 120 is shaped to be seated on one side of the fixing member 110. Between the secondary roller 113b and the tertiary roller 113c of the fixing member 110, the driving roller 122 of the operating member 120 of the rope conveying unit 110a is seated and mounted on the tape-type rope 101. The descender 100 will be able to descend.

2 is a cross-sectional view showing a safety rope lowering device equipped with a double brake device according to an embodiment of the invention, Figure 3 is an operation of the lock lever of the safety rope lowering device equipped with a double brake device according to an embodiment of the invention. It is sectional drawing which showed state.

The descender 100 combining the fixing member 110 and the operation member 120 is mounted on the tape-type rope 100.

The tape-type rope 100 flows into the rope inlet 112a formed at the front end surface of the fixing member 110 and passes through the left side of the primary roller 113a formed inside the rope inlet 112a. It flows into the right side of the secondary roller 113b.

Thereafter, the tape-type rope 101 passes through the rope conveying part 110a formed between the secondary roller 113b and the tertiary roller 113c, and forms a rope outlet groove 120a of one side formed in the operation member 120. Through the drive roller 122 is introduced, the rope 101 past the drive roller 122 is discharged to the rope outflow groove 120a of the other side, it is introduced through the rope outflow groove 120a of the fixing member and tertiary It flows into the right side of the roller 113c.

The rope conveying part 110a is formed to be inclined so that the wall surface is inclined so that the rope 101 is transferred to the driving roller 122 having a diameter larger than that of the secondary roller and the tertiary roller, thereby forming the same inclined surface as the inclined angle. By doing so, the tape-type rope 101 is carried on the inclined slope of the wall surface.

In addition, the size of the rope transporting portion (110a) must be formed to a size smaller than the combined size of the diameter of the drive roller support (122a) formed on the operation member 120 and the width of the tape-type rope.

As described above, the descending machine 100 of the present invention is a state in which the driving roller support part 122a and the rope conveying part 110a are joined to each other, and the third roller 113c is turned again by turning the driving roller 122 from the secondary roller 113c. While passing, the tape-type rope is passed through the rope conveying portion (110a) and the rope outlet groove (120a).

At this time, after the tape-type rope 101 is passed through the rope transfer part 110a, the driving roller support part 122a is fixed in a state of blocking the rope transfer part 110a, and the descender 100 is tape-type rope 101. Will be fastened to.

The tape-type rope 101 passing to the right of the tertiary roller 113c flows into the lower portion of the brake plate 115.

The brake plate 115 is integrally coupled with the locking lever 114 of the fixing member 110 so that when the locking lever 114 is turned to one side, the locking lever 114 is raised and the brake plate 115 is also locked. Since it is described in detail together with the lever 114, the space between the bottom surface of the fixing member 110 and the brake plate 115 is wide and there is no obstacle to the descender is transported down at high speed riding the tape-type rope 101 do.

On the other hand, when the lock lever 114 is closed in the opposite direction, the lock lever 114 is lowered, and the brake plate 115 is also lowered, so that the bottom surface and the space of the fixing member 110 are tightly closed and tape-type ropes ( 101) to friction.

Therefore, in the state where the descender descends on the tape-type rope 101, the lowering speed is lowered due to friction, and when the lock lever 114 is completely locked, the brake plate 115 adheres to the rope to maintain the stopped state.

This means that when the user is bound to the hook 116 of the descender 100, the weight is lowered due to the user's weight, but the lock lever 114 and the brake plate 115 are lowered quickly according to the user's weight.

Thereafter, the tape-type rope 101 passing through the lower portion of the brake plate 115 flows into the right side of the fourth roller 113d formed at one side of the rope outlet 112b, and the outside through the rope outlet 112b. Spills into.

The tape-type rope 101 is introduced to the left in the primary roller (113a), the fourth roller (113d) flows out to the right, the descender 100 in a state where several users are fastened to the descender (100) To prevent it from tipping to one side.

On the other hand, as shown in Figure 2, in the state where the descender 100 is fastened to the tape-type rope 101, when the load is loaded on the descender 100, that is, a person or heavy equipment, etc., the secondary roller Since the 113b and the tertiary rollers 113c are pulling the driving rollers 122 with the tape-type band 101, the driving rollers 122 are pulled toward the fixing member 110 by the load on the buckle. do,

Therefore, as shown in 3, the drive roller support portion 122a for supporting the drive roller 122 is also closed by pressing the rope outflow groove (110a) by the pressure pushed toward the fixing member (110).

At this time, the band 101 in the outflow, inflow state from the rope transfer part 110a is tightly held by the pressure of the driving roller support part 122a to maintain a closed state so that the descending device 100 that is lowered can stop.

The rope groove groove 120a formed around the drive roller support part 122a is a groove formed so that the rope 101 passes through the drive roller 122 of the operation member 120, and at the same time, the load of the descender 110 is increased. By this, the drive roller 122 and the drive roller support part 122a make it easy to crimp the rope conveyance part 110a.

3 illustrates a state in which the tape-type rope 101 is impossible to move by allowing the brake plate 114 to be in close contact with the bottom surface of the fixing member 110, and the operating frame 123 and the fixing lever 114 are taped. It is to act as a brake so that the flow of the type rope 101 is impossible.

therefore. Even if the lock lever 114 of the descender 100 mounted on the tape-type rope 101 does not operate due to a failure or damage, it can be safely lowered by the operation of the operation frame 123.

Figure 4 is a perspective view showing the operating state of the safety rope lowering device equipped with a double brake device according to an embodiment of the present invention, Figure 5 is a safety rope lowering device equipped with a double brake device according to an embodiment of the present invention. This is a cross-sectional view showing the operating state of.

When the operation frame 123 of the operation member 120 is flipped, the stepped portion 124 of the end of the operation frame 123 is moved over, and at the same time, the entire operation member 120 is lifted upward.

At this time, the tape-type rope 101 is also pulled into the right side of the secondary roller 113b and passed through the driving roller 122 to the right side of the tertiary roller 113c.

In addition, the driving roller 122 and the driving roller support part 122a, which are pressed by pressing the rope transporting part 110a, are spaced apart to open the rope transporting part 110a.

Therefore, the tape-type rope 101 that could not flow in a tight state in the rope transfer part 110a is in a state in which the descender 100 can descend to the rope lower portion.

This means that even if a large pressure is received by the weight of the user of the descender 100, the brake function occurs to stop the lowering or reduce the lowering speed unless the operating member is opened.

Therefore, when the lock lever 114 and the operation frame 123 are used together, it is easier to maintain the stop state, and even if any one of the lock lever 114 or the operation frame 123 causes a failure, Can be used safely during rescue.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
