Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cradle of a rope-

There are many high-rise buildings over 15 floors in Korea. When a fire occurs in such a high-rise building, it is difficult to suppress the fire quickly with domestic fire fighting equipment or fire fighting technology.

Therefore, when a fire occurs in a high-rise building, various methods for escaping a person are emerging, one of which is a landing gear using a rope.

The rope lift device is an engine type power lift device and is used for escaping a person by using a rope or a string in the event of a dangerous situation.

The rope-like lift apparatus can help a person escape from a fire scene to a safe place by using a rope when a dangerous thing such as a fire occurs in a high-rise building such as a high-rise apartment building or a building. When the person is hung on the rope of the rope lift device, the rope slowly falls to the ground and moves to a safe place to escape.

For example, in U.S. Published Utility Model No. 1998-026059, A pulley for hoisting the loop; A deceleration portion for decelerating a rotation speed of the pulley; A coupling plate for coupling the loop, the pulley, and the deceleration portion; And a cover plate coupled to the upper direction of the coupling plate, and the like.

In addition, in the patent No. 1311643, since a deceleration effect is first applied to a V-type brake, even if a solid wheel is hung on a deceleration wheel, a load is felt as if a low weight is hanged, , And further, since the V-type brake is responsible for part of the body weight of the evacuator, the fatigue of other heavy-duty parts is reduced and the long-term rigidity can be used.

However, in the case of the above-mentioned stabilizer, only the building of 10 stories or less is installed, and when the fire is actually used, the usage method is not known or the use frequency is extremely low due to the hall alone.

At this time, the construction methods by firefighters or firefighting equipments are largely classified into high-priced ladder cars and rope-based firefighters. High-priced ladder cars have many problems in accessing vehicles due to the structure and characteristics of domestic buildings (illegal parking, The characteristics of the structure). Due to these reasons, it takes a lot of time and it is often difficult to respond to urgent structural matters.

In addition, the structure using rope or reel is mainly used for the structure of the rope, and since it is required to descend and stop using the hand, there is a considerable strength and danger.

However, the method using the rope or reel has advantages of convenient transportation and use of the equipment, and thus it is widely used in other construction sites.

For example, in a manhole fall accident site, a tripod reel is used. In this case, several people have to support a tripod reel. Also, in a mountainous structure site, a reed is used to rescue a victim. And it is difficult to tow at least 2-3 people in order to lift an injured person.

FIG. 1 is a perspective view of a rope-type landing gear according to the present invention, viewed from the left side. And Fig. 2 is a perspective view of the rope lift device according to the present invention as seen from the right side.

The rope-type elevator according to the present invention is an apparatus that mounts an engine or a motor directly in the driving unit 1 and safely raises or lowers a load within a certain weight range by the engine power. The driving unit 1 includes a prime mover, a clutch connected to the rotary shaft of the prime mover, and a brake.

Preferably, the prime mover is implemented as a motor or an engine. When a strong driving force is required, the engine is preferably applied. When the motor is used and the weight is relatively small, the prime mover is preferably implemented as a motor.

It is preferable that the clutch and the brake are configured to be operated by a control module 5 which will be described later by applying an electromagnetic type and a configuration in which the control module 5 performs an operation of a clutch and a brake .

The rope-type landing gear of the present invention includes a rope drum 19 connected to the output shaft of the driving unit 1 and rotated, and the rope-type landing gear of the present invention includes a rope drum 19 for raising or lowering the rope- 21 are wound. Although not shown, the rope drum 19 has a V-groove formed in its side surface, and a step or the like for increasing the friction with the rope 21 is formed on the inner surface of the pulley groove.

Therefore, the rope 21 is wound around the rope drum 19, and the rope drum 19 is rotated by the driving force of the driving unit 1 to raise or lower the rope-type lift apparatus of the present invention.

The rope-like lifting device of the present invention that operates as described above is equipped with a double safety device including an electronic braking device 15 and a mechanical braking device 9. [ The electronic braking device (15) is configured to be under the control of the control module (5).

The electronic braking device 15 controls the raising and lowering and stopping operations of the rope-type landing gear of the present invention by electrically controlling the clutches and brakes in the driving part 1.

The electronic braking device 5 has a function of restricting a load to be loaded and a speed limiting function of preventing rapid descent. In the embodiment of the present invention, the maximum allowable weight is 250 kg, while the appropriate load for lifting and lowering is preferably 120 kg or less. It is appropriate that the lifting speed when lifting up through the electronic braking device 5 is 0.26 m / s at maximum and the downward speed is 0.3 m / s at maximum. The elevating speed and the descending speed are examples when the load is 120 kg.

The control module 5 includes a load sensing device 13 for sensing the load on the rope elevating device using a load cell or the like and a descending speed measuring device 11 for measuring speed and direction using a magnetic sensor or the like And a detection signal from the RFID module 7 and the like, and generates signals for controlling the up, down and stop operations of the electronic braking device 15. [

The rope-like lifting device of the present invention further includes a battery 3 for supplying power to an electrical device requiring electricity including the control module 5 and the electronic braking device 15. [

Therefore, the control module 5 raises and lowers the rope-like lifting device of the present invention at an appropriate speed through the electronic braking device 15 based on the detection signals of the load sensing device 13 and the descending speed measuring device 11 And controls the operation. At this time, the control module 5 can also perform a control of decelerating the speed at a time of rising above a predetermined speed based on the detection value of the descending speed measuring device 11. [

On the other hand, the mechanical braking device 9 is a device for mechanically raising and lowering the braking device 5 when the brake function of the electronic braking device 5 is broken.

3 shows a cross-sectional view of a mechanical braking device in a rope-like lifting device according to the present invention, showing a locked state. Fig. 4 shows a cross-sectional view of a mechanical braking device in a rope-like lifting device according to the present invention, showing a released state.

The mechanical braking device 9 of the present invention can mechanically press the rope 21 wound on the rope drum 19 to prevent it from moving as shown in Fig. As shown in FIG. 4, the mechanical braking device 9 of the present invention can release the rope 21 by a certain amount of pressure so that the rope can be moved by a predetermined amount.

The mechanical braking device 9 of the present invention includes a support 24 for supporting the mechanical braking device 9 on a base (not shown) for supporting the whole device, And a rotating body 25 supported by the supporting portion 24 and pressing the rope 21 by rotation of the unlocking lever 23.

The mechanical braking device of the present invention includes a connecting portion 31 that is coupled to the unlocking lever 23 and is advanced forward by a predetermined amount by rotation of the unlocking lever to rotate the rotating body 25 clockwise by a predetermined amount And a stopper 29 for restricting the rotation of the rotating body 25.

More specifically, the support portion 24 is configured to fixly mount the mechanical braking device on the base. The support 24 supports the mechanical braking device 9 in its entirety on the base.

As shown in Figs. 3 and 4, the lock release lever 23 is configured to be rotatable in a range of approximately 180 degrees from the top to the bottom. When the release lever 23 is in the position shown in FIG. 3, it is locked. When the release lever 24 is in the position shown in FIG. 4, the release lever 23 is released.

The connecting portion 31 is connected to the unlocking lever 23 to rotate the rotating body 25 clockwise by advancing in the direction of the arrow when the unlocking lever 23 is rotated downward. When the lock release lever 23 is returned to the upper position, the rotating body 25 is also returned to its original position. A spring for advancing the connection portion 31 is included in the connection portion in conjunction with the upward / downward rotation of the release lever 23.

An important point in the interlocking operation between the connecting portion 31 and the rotating body 25 is that the rotating amount by which the rotating body 25 is rotated in the clockwise direction is determined by the advancing amount of the connecting portion 31. 4, the rotating body 25 rotates clockwise by an amount corresponding to the advancement of the connecting portion 31, thereby lowering the pressing force applied to the rope 21. As shown in FIG. 4, the rotating body 25 Is rotated in the clockwise direction, the pressing force applied to the rope 21 becomes weaker than the state shown in Fig.

The stopper 29 is fixedly mounted on the support portion 24 or the base so as to restrict the amount of rotation of the rotating body 25 in the counterclockwise direction and is applied to the rope 21 by the rotating body 25 So as to support the pressing force. The stopper 29 is configured to pass the rope 21 and the rotating body 25 presses the rope 21 passing through the stopper 29. The rope 21 having passed through the stopper 29 is wound around the rope drum 19 for one rotation so that the rope is moved from the upper portion to the lower portion or from the lower portion to the upper portion by the rotation of the rope drum 19 . And a serrated shape is formed downward at a portion where the rotating body 25 is engaged with the rope 21.

The mechanical braking device 9 of the present invention configured as described above is operated as follows.

The rope-like lifting device of the present invention provides power for lifting and lowering operations while being suspended from the rope 21, at which time a person can be raised or lowered together with the rope lifting device.

However, when the electronic braking device 15 that controls the rising and falling operations using the power of the rope-type landing gear is broken, the mechanical braking device 5 is forcibly controlled as shown in Fig. 3, Stop the movement.

That is, the rotation of the rotating body 25 in the counterclockwise direction is limited by the stopper 29. At this time, the rotating body 25 strongly presses the rope 21 configured to pass through the stopper 29, (21) is prevented from moving.

4, when the lock release lever 23 is rotated downward, the connection portion 31 connected to the lock release lever 23 advances by a predetermined amount in the direction of the arrow. The connecting portion 31 is advanced and pushes the rotating body 25 and the rotating body 25 is rotated in the clockwise direction by the forward amount of the connecting portion 31.

With this operation, the rotating body 25 is rotated in the clockwise direction within the rotation limit range of the stopper 29, so that the pressing force applied to the rope 21 from the rotating body 25 becomes a predetermined weakened state.

Thus, when the pressing force applied to the rope 21 is weakened by a predetermined amount, it is possible to slightly lower the load by the load composed of the rope-like lifting device and the person. Of course, in this process, the pressing force applied to the rope 21 is reduced to a very small extent as compared with that in Fig. Since the teeth of the rotating body 25 are engaged with the rope 21, the movement of the rope is very limited. However, it is possible to descend gradually to the ground due to the load and gravity of the rope-type lifting device hanging from the rope in the air.

Therefore, if the process of reciprocating the lock lever 23 in the range of 180 degrees is repeatedly performed, the mechanical braking device is repeatedly locked and unlocked, so that the rope is slightly moved, It is possible to safely lower the teeth to the ground.

On the other hand, the rope-like lift apparatus of the present invention is used in a high-rise building. Therefore, in order to use the rope-type lift device, the holder is fixedly mounted on the roof of the building, and the rope is used after the rope is connected to the holder. Therefore, in order to use the rope-like lifting device, it is necessary to provide a cradle which can be securely fixed.

Figs. 5 to 7 show a state where the cradle of the rope-like lift device of the present invention is installed on the top of the building roof wall.

The cradle is constructed such that the thickness of the building square wall can be assembled in a range of 120 mm to 400 mm.

The cradle shown in Fig. 5 uses all four members. All the members used in the present invention are configured to use the same members but to be combined in different directions only.

The member constituting the cradle is an A member shown in Fig. 9A. Five of the A members are installed vertically in the upper part of the square wall shown in Fig. 5, two in front of the wall and two behind the wall. For example, when the cradle is installed on the roof wall, the cradle is installed by supporting the front wall and the rear wall of the roof wall.

Referring to the A member 100 shown in Fig. 8A, the large frame is formed in a shape. The three members are integrally formed by bolt connection, welding or metal mold to form the A member.

Each of the first members 101 has a substantially T-shape. And the second member 102 is formed in the same T-shape as the first member 101. The first and second members (101, 102) are located in the horizontal direction in the figure and are positioned in an eleven character.

And the third member 104 positioned in the longitudinal direction of the drawing extends perpendicularly to the first and second members at the center portion of the eleven-figure shape. The third member 104 is also substantially T-shaped.

8A, the first member 101 and the second member 102 are placed in an eleven-letter form with the T-shape lying down, and the third member 104 is placed with the T-shaped standing , The three members are assembled together using a bolt, or assembled together using welding or the like. Of course, it is also possible to constitute the three members integrally by injection molding such as a mold. The member should be constructed of a sturdy material, such as a reinforcing bar, that is very rigid and does not change its characteristics.

In the A-member structured as described above, the head portion (transverse portion) in the T-shape of the first, second and third members constitutes the protrusions 106 and 110. That is, the protrusions 106 are formed on the upper portions of the first and second members 101 and 102, and the protrusions 110 are also formed on the third member 104. That is, in assembling the A member by connecting the three members, one side of the T-shaped head portion (transverse portion) is centered on the body portion (vertical portion), and the other side is used as a threaded portion It is possible to explain that. The protrusions 106 and 110 are formed with connection rings 108 and 112 for mounting a line member for binding ropes.

A plurality of screw grooves 114 and 116 for screw connection are formed in the three members 101, 102 and 104. The first, second, and third members are basically formed into a square pillar shape, and the screw grooves are formed in many numbers on all sides of the square pillar.

FIG. 8B shows a cross-sectional view of the A-member of FIG. 8A as viewed in the " A "direction. That is, it is shown that the A member is formed in a shape, the first member 101 is formed in the transverse direction, and the third member 104 is formed in the longitudinal direction. A second member 102 is constructed overlapping with the first member 101, but is not shown in Fig. 8B.

A protrusion 106 formed at an edge portion toward the upper side and another protrusion 110 formed at a right angle to the protrusion 106 are formed.

Fig. 8C shows a cross-sectional view of the A-member of Fig. 8A viewed in the " B "direction, and Fig. 8D shows a cross-sectional view of the A-

The four members A constituted as described above are connected to constitute a cradle capable of safely supporting the rope-type lift apparatus. When the four members A are connected to each other to constitute a cradle, the third member 104 and the first and second members 101 and 102 are limited in size so that they can be assembled. That is, the three members (104) are inserted into the central positions of the eleven first and second members (101, 102) so that the three members are joined together by one screw at the side of the first, .

Therefore, when the first member 101 and the second member 102 are positioned in an 11-letter form, the third member 104 is inserted into the first member 101 so that the side surfaces of the first and second members are in contact with the side surface of the third member 101 The size should be limited. In order for the first, second, and third members to be screwed together by one screw, the screw grooves of the three members should be arranged in a straight line.

As shown in Figs. 5 to 7, the cradle of the rope-type elevator according to the present invention is installed so as to surround the periphery of the pillar as shown in Figs. 9A to 9D, .

When installed vertically on the wall, it is exemplified that it is installed on the roof wall. When installed on the roof wall, the two A members are fixed to the front portion of the roof wall and the rear portion of the roof wall using screws 208, respectively, corresponding to the thickness of the roof wall. In this case, if the A-member 200 installed at the front portion of the wall is installed in the direction of FIG. 8A, the A-member 210 installed at the rear portion of the wall is inserted from the upper portion of the A- State. The first and second members of the A member (200) and the A member (210) are coupled together by a single screw (202) in such a manner that the screw grooves formed on the side surfaces of the respective members are aligned. The screws 204 also show the same coupling.

Similarly, two A members are used to secure the front portion 230 of the wall and the rear portion 220 of the wall, and the two A members are joined together.

When assembled in this way, it is like a state of being installed on the vertical wall shown in Fig. Since the two A members 200 and 230 installed on the front wall are installed in the same shape as FIG. 8A, two connecting rings 112 of the two A members 200 and 230 are positioned at the front end of the front wall, Two connection rings 108 of the two A members 200 and 230 are located on the upper side.

The connection rings 112 of the two A members are supported through the line member 206 and the connection rings 108 of the two A members are supported through another line member 240. The line member 206 is bound to the rope so as to support the vertical movement of the rope-like lifting device.

Two connection rings 110 are projected upward from the two A members 210 and 220 provided at the rear portion of the roof wall as in the front portion of the roof wall. The line member 245 is also connected to the connection loop 110 to support the assembled state of the assembled A members.

Next, in the case of mounting the mount on the column, the A member located as shown in FIG. 8B is assembled into a rectangular shape as shown in FIG. 9B.

In this case, the a-shaped A-shaped members are screwed together in a state of being opposed to each other. According to the thickness of the column, the assembly size can be adjusted by changing the position of the screw groove to which the two members are screwed as shown in Figs. 9B, 9C, and 9D.

9A, a configuration in which another third member 104 of the A member is engaged between the first and second members 101 and 102 having the 11-letter shape of the A member Lt; / RTI > Accordingly, the first, second, and third members are coupled to the common thread 300 through a single screw.

And the cradle is screwed to the column wall. That is, all of the partial members constituting all of the A members constituting the cradle are formed into a square pillar shape, and a plurality of screw grooves 320 are formed in each square pillar. Therefore, the screw is fixed to the column wall through the screw groove.

Accordingly, the foregoing detailed description should not be construed in any way as limiting and should be considered illustrative.
