Description

Safety rope and steel combine

The present invention relates to a safety rope and a downhill combine device, and more particularly, a safety rope and a downlink combiner that can be used as a safety rope that can lower the descending speed as well as a dropper that can quickly escape to the outside of a building during a disaster. Relates to a device.

In general, the stiffener is a mechanism for quickly escaping a person inside the building outside the building when a disaster such as a fire occurs in a multi-storey building. Such a boom is to combine the boom with a rope provided on the upper inner wall of the building window in the event of fire and other emergencies, and then the user can descend from the boom to escape from the danger. In addition, the safety rope is used for the safety of the operator when performing work at a high position.

As such, the conventional downhill for emergency escape is configured to descend on a rope vertically provided in the building, so when the weight of the person using the downhill is heavy, slippage occurs in the rope and the brake of the downhill device does not operate.

Centrifugal weight 144 provided with 144a and the other end 144b that is heavier than the one end 144a, Lining 146 provided on the radially outer side of the centrifugal weight 144, Radial of the lining 146 It is provided on the outside and characterized in that it comprises a brake drum 148 in contact with the lining 146 according to the position of the centrifugal weight (144).

Hereinafter, the present invention will be described in more detail with reference to preferred examples. However, these examples are intended to illustrate the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited thereby.

Figure 2 is a cross-sectional view of the safety rope and the combine device according to an embodiment of the present invention, Figure 3 is a rear view of the safety rope and combine device according to an embodiment of the present invention.

The safety rope and the combine device as shown in Figure 2, as shown in Figure 2, largely interlocked with the rope, and receives the rotational force of the rope drum 120 is divided into a rear portion for adjusting the descending speed of the rope mounted on the descender Can be. That is, the rotation transmission beam 130 fixedly coupled to the rotation hole 124 of the rope drum 120 is rotated at the same time when the rotation hole 124 rotates, the rotational force of the rotation transmission beam 130 is brake device It is transmitted to the brake drive plate 142 of (140). Thus, the rotational force of the rope drum unit 120 can be obtained to the effect transmitted to the brake unit 140. Since one end of the centrifugal weight 144a is axially coupled to the brake drive plate 142, when the brake drive plate 142 rotates, the centrifugal weight acts on the other end of the centrifugal weight 144b formed more heavily than the centrifugal weight one end 144a. The lining 146 provided on the radially outer side of the 144 is pushed. When the lining 146 moves radially outward by the centrifugal weight 144, the lining panel 146p formed of a material having a high friction force such as rubber comes into contact with the brake drum 148, thereby causing the centrifugal weight 144. And while the rotational speed of the brake drive plate 142 is lowered, the speed of the rotary sphere 124 is lowered. Therefore, the moving speed of the rope moving in the state seated on the rope guider 122 using the rope drum 120 as a pulley is lowered.

First, the structure of the rear part of the safety rope and the lower device combined with the brake device 140 is installed, as shown in FIG. 3, the brake drive plate 142, the centrifugal weight 144, the lining 146, and the brake drum 148. ) Is included. The brake drive plate 142 is fixedly coupled to the rotation transmission beam 130 and is driven by the rotational force of the rotation transmission beam 130. Here, the brake drive plate 142 may be provided in various shapes, such as a disk shape or a polygonal plate shape, but in order to reduce the material, as shown in FIG. Can be. That is, the brake driving plate 142 may be formed in two directions or three directions or more in accordance with the point where the one end of the centrifugal weight 144a is coupled. The centrifugal weight 144 has a shape different from one end 144a and the other end 144b so that the lining contact surface 144c contacting the lining 146 is convex, and the opposite surface 144d is concave, Centrifugal force is effectively transmitted to the other end of the centrifugal weight 144b. In addition, by forming the lining contact surface 144c into a convex curved surface, the contact area of the centrifugal weight 144 and the lining 146 can be increased. In addition, one end of the centrifugal weight 144 may be coupled to the centrifugal weight restoring spring S ₁ positioned at the central portion of the brake driving plate 142. Centrifugal weight restoring spring (S ₁ ) is to cause the centrifugal weight (144) moving radially outward by the centrifugal force to return to the radially inward, so that the centrifugal weight (144) is returned radially inward when the centrifugal force is less than a certain intensity. That is, when the rotational speed of the rope drum 120 increases, the centrifugal force is larger than the restoring force of the centrifugal weight restoring spring S ₁ , so that the centrifugal weight 144 moves radially outward, and the lining 146 is the brake drum 148. ) To pressurize. In addition, when the rotational speed of the rope drum unit 120 is slow and the centrifugal force is smaller than the restoring force of the centrifugal weight restoring spring S ₁ , the centrifugal weight 144 is restored to its original position, thereby speeding up the speed of the rope drum part 120. To be faster again.

The centrifugal weight restoring spring S ₁ may be coupled to a rotating body 145a protruding from the central portion of the brake driving plate 142, in particular, on the brake driving plate 142 so as to be rotatable. The rotating body 145a is interlocked with the rotation fixing body 145b to fix the state rotated at a predetermined angle from the brake drive plate 142. That is, the spring restoring force adjuster 145 including the rotating body 145a and the rotating fixing body 145b may be installed on the brake driving plate 142. By coupling one end of the shock absorbing spring to the spring restoring force regulator 145, it is possible to adjust the restoring force of the shock absorbing spring according to the weight of the user of the safety rope and the wan combine device. For example, when there is a user having a low weight, a medium weight, and a heavy weight, as shown in the enlarged view of FIG. 3A, the low weight user puts the rotating body 145a in one step so that both ends of the shock absorbing spring are straight. When the rotation state is fixed by the rotation fixing body 145b, the restoring force acts as much as the original restoring force R ₁ of the shock absorbing spring. In addition, when the user of the intermediate weight using the safety rope and the device combines, the restoring force (R ₂ ) in the centrifugal weight (144) because the spring is longer than the original length when the rotor 145a is placed in a two-stage state This will work. That is, in the case of the user of medium weight, the weight is heavier than the user of the low weight, so when the rotational speed increases, the centrifugal weight 144 immediately moves radially outward, and thus a greater restoring force (R ₂ ) can be prevented. To make it work. Similarly, in the case of a heavy user, when the rotating body 145a is placed in the three-stage state and fixed by the rotating fixing body 145b, a greater restoring force R ₃ is applied to the shock absorbing spring. In this way, the restoring force acting on the shock absorbing spring can be measured according to the length of the spring extension within the elastic limit. can do. In addition, the lining 146, like the centrifugal weight 144, also has a lining restoring spring (S ₂ ) for restoring its position when the rotational force is a predetermined size or less, the state in contact with the brake drum 148 when the rotational speed is slow You can get away from it.

Figure 4 is a front view of the safety rope and gangbang combined device with a rope drum unit according to an embodiment of the present invention is shown, Figure 4a is a front view of the safety rope and gangbang combine device when used as a safety rope, Figure 4b shows a front view of the safety rope and the combine device when used as a lay.

Safety rope and steel bar combine device according to the present invention, as shown in Figure 4a, to form an annular fastening ring (152a) on one end 152 of the rope portion 150, the separate fastening to the annular fastening ring (152a) Rope 159 may be provided. In general, since the work of wearing the safety rope does not end in a short time, most workers move with the safety rope worn between working hours. In other words, it is cumbersome to remove the safety vest connected to the safety rope from the body, and then carry the safety rope to the ground. Therefore, the present invention is provided with a fastening rope 159 that can be easily attached and detached so that the operator does not need to carry the entire safety rope in this way. When the fastening rope is provided in this way, the worker can increase the convenience of the worker because only the light fastening rope 159 needs to be carried around without carrying the heavy safety rope. The annular fastening ring 152a formed at one end 152 of the rope part 150 is illustrated to easily understand the shape, and may be formed to be different from the ratio shown in the drawings.

If you want to use the safety rope and the device combine as a safety rope, the other end 154 of the rope portion 150 is long down to the bottom so as to minimize the shock received by the wearer initially. Therefore, the operator connected to one end 152 side of the rope portion, when the one end 152 of the rope portion 150 is moved to the lower when the brake device unit 140 is operated, unlike the conventional safety rope to lower the falling speed of the worker To reduce the impact on the operator. In addition, an annular fastening ring 154b may be formed at the other end 154 of the rope part 150, wherein the annular fastening ring 154b is a safety rope spring 156 located at the other end 154 side of the rope part 150. It is preferable that the larger than the inner diameter of the safety rope spring 156 so as not to escape. Here, the safety rope spring 156 is fixedly coupled to one end of the case 110, so that when the other end 154 of the rope part 150 moves toward the case 110, the safety rope spring 156 is compressed based on one end of the safety rope spring 156. As the wearer descends, the buffering effect can be obtained.

In addition, if you want to use the safety rope and gangbang combine device as a wan, as shown in Figure 4b, after removing the rope portion 150 mounted on the safety rope and wan combine device, of the auxiliary brake unit 160 The stiff rope 1 may be inserted between the auxiliary drum 164 and the rope drum 120 to escape. That is, by adjusting the position of the auxiliary brake unit 160, it is possible to position the stiff rope (1) therebetween. Here, as shown in the enlarged view of FIG. 4B, the rope guider 122 of the rope drum 120 may have irregularities.

The auxiliary brake unit 160 presses the rope seated on the outer circumferential surface of the rope drum unit 120 or the rope drum unit 120 in the case 110.

Rotating is formed in the vertical direction of the case 110, provided with one end 162a axially coupled to the case 110, and the other end 162b exposed through the passage of the case 110 to the outside Conditioning beam 162, and

A pair of auxiliary drums 164 are axially coupled to the rotation control beam 162 so as to press the outer circumferential surface of the rope drum 120 according to the position of the rotation control beam 162. .

The wearer using the wan is lowered by holding the handle 174 at the beginning of the escape. Here, the ends of the handle 174 may be bent or curved to prevent the hand from slipping down, and the handle 174 may be formed by forming a hollow in the handle 174 to insert a hand into the hollow and then holding the handle 174. ) May be provided. In addition, by having a safety ring 190 on the outer circumferential surface of the case 110 and a rope coupled to the body part of the wearer on the safety ring 190, even when the handle is missed, the safety ring 190 is coupled to the state. You will be able to evacuate safely on the descent.

At this time, if the frictional force is not sufficiently given to the stiff rope 1 located between the auxiliary brake 150 and the rope drum 120 according to the weight of the wearer, the rope drum 120 is slipped with the stiff rope 1 You make contact. As such, when the rope drum part 120 and the stiff rope 1 make sliding contact, the brake device part 140 is not driven because the rope drum part 120 does not rotate. Therefore, the auxiliary brake unit 150 is driven so that the brake device unit 140 is driven when the safety rope and the steel bar combine the lower rope 1 and the rope drum unit 120 to make a rolling contact with each other. ). In addition, by providing the concave-convex (122a) to the rope guider 122, it is possible to provide a rough surface of the rope guider 122 in contact with the stiff rope 10 to increase the friction force.

Here, the position restoring spring 166 may be coupled to the rotation control beam 162 of the auxiliary brake unit 160. The position restoring spring 166 acts in a direction in which the pair of auxiliary drums 164 of the auxiliary brake unit 160 presses the rope drum unit 120 or the rope unit 150. To this end, one end of the position restoring spring 166 is coupled to the case 110 and the other end is coupled to the rotation control beam 162.

The auxiliary brake unit 160 mounted on the safety rope and the downcomer combined device according to an embodiment of the present invention allows the wearer to directly move the rotation control beam 162 so that the auxiliary drum 164 contacts the rope drum unit 120. Although the state may be adjusted, the contact state of the auxiliary drum 164 and the rope drum unit 120 may be adjusted by providing a device capable of fixing the position of the rotation control beam 162. To this end, the auxiliary brake unit 160 is equipped with a driving holding hole 167. Since the driving retention hole 167 is interlocked with the rotation control beam 162, the fixing of the rotation control beam 162 is determined according to the position of the driving retention hole 167.

The driving retention hole 167 may include an arc-shaped gear 167a, an articulator 167b engaged with the gear 167a, and a transmission body 167c connected to the articulator 167b. . The driving retainer 167 is coupled to the rotation control beam 162 and the hinge to move the rotation control beam 162 to the rope drum 120 side after the articulator 167b moves the position on the gear 167a It is fixed to the stiff rope (1) can increase the degree of friction acting on the auxiliary brake unit 160 and the rope drum 120.
