Description

Technical Field

[0001] The invention relates to an escape device, in particular to a high-rise vertical escape device used as a high-rise escape device. Background Art

[0002] Since elevators in general high-rise buildings are prone to stop working due to power outages when a fire occurs, and escape ladders are often blocked by fire, many high-rise buildings often have slow-descent escape devices installed as backup escape devices when the building's escape ladders are blocked by fire.

[0003] Existing slow-down escape devices usually use rope hanging to hang escapees from the outside of the building to the ground. However, such existing slow-down devices are prone to shaking during use and lack protection for personnel. Therefore, escapees are easily injured during the descent process, and users with poor physical strength in the fire scene cannot use it smoothly.

[0004] Therefore, fixed slow-down escape ladders appeared on the market later. However, the structure of existing fixed slow-down escape ladders is usually too complicated, and the mechanism is prone to failure. Therefore, they cannot be widely used and have poor reliability.

[0005] Due to the above reasons, there are various disadvantages in the use of the existing slow-down escape device. Therefore, how to solve the above problems by improving the structural design has become one of the important issues that the industry wants to solve. Summary of the invention

[0008] The locking nut is secured to the locking nut by a second locking mechanism, the locking nut being secured to the locking nut by a second locking mechanism, the locking nut being secured to the locking nut by a second locking mechanism, the locking nut being secured to the locking nut by a second locking mechanism.

[0009] Furthermore, the nut stop pin is used to keep the split nut structure in a stationary state before the rappelling preparation action is completed.

[0010] Furthermore, the combining disc is provided with an axle rod combining hole and a safety pin combining hole on both sides of the groove section of the load nut rotor, and the two halves of the load nut rotor are tightly combined by using an arc-shaped covering clamp, and the safety pin combining hole is inserted by using a first safety pin to control the opening and closing of the load nut rotor.

[0011] Furthermore, the load-bearing nut rotor rotates downward under the force, and its rotational momentum causes multiple outer ring thrust rollers, inner ring thrust rollers, and middle ring thrust rollers on the fixed positions of the upper cover and the lower cover to roll and offset in the outer ring guide groove, the inner ring guide groove, and the middle ring guide groove, thereby not causing the upper cover and the lower cover to rotate, allowing the high-rise vertical escape device to stably suspend the escaping personnel and vertically descend.

[0012] Furthermore, the fixing mechanism at the top of the screw rod is provided with a certain pulley and a fireproof pull rope. After being lowered, the opening and closing nut structure and the escape wearable equipment are manually transferred to the required floor for reuse through the fixed pulley and the fireproof pull rope.

[0013] Furthermore, the vertical descending screw rod is formed into any length through segmented splicing technology, wherein a concentric hole is arranged on the screw rod section, and the upper and lower sections of the screw rod are perfectly spliced ​​together with a corresponding solid splicing column, and a thread positioning hole is arranged at the relative position between the screw rod section and the thread, and the upper and lower sections of the screw rod threads are accurately aligned with a corresponding positioning column, so that the opening and closing nut structure can move smoothly without hindrance during the entire section of the screw rod, and the high-rise vertical descending escape device is not restricted by the floor height.

[0014] Furthermore, the descending screw rod is provided with several one-way opening and closing elastic U-shaped clamps at fixed intervals to stabilize the screw rod. When the one-way opening and closing elastic U-shaped clamps are in a normal state, the one-way opening and closing elastic U-shaped clamps will clamp the screw rod. When a person slides down, the one-way opening and closing elastic U-shaped clamps will bend downward and leave the screw rod under the force. After the person passes, the one-way opening and closing elastic U-shaped clamps will return to their original positions under the action of elastic force to keep the screw rod stable. In a normal state, the one-way opening and closing elastic U-shaped clamps will be perpendicular to the screw rod and will be arranged alternately in multiple directions, with the one-way opening and closing elastic U-shaped clamps facing away from the wall, or with the one-way opening and closing elastic U-shaped clamps parallel to the wall to the right, or with the one-way opening and closing elastic U-shaped clamps parallel to the wall to the left.

[0015] Further, the escape wear device is a life jacket with multiple hooks.

[0016] The camming mechanism of the present invention is simple and can be used for the lift truck, and the lift truck can be used for the lift truck by the user.

[0017] Furthermore, the present invention has a simple structure and is easy to operate. Each safety pin controls the opening and closing of the split nut structure for vertical descent, which allows the high-rise vertical descent escape device to stably hang and descent the escapee. The arc-shaped enveloping fixture is combined with the shaft rod combination hole to form a fixed end by using an axle rod, and the other end is combined with the first safety pin combination hole on the other side of the load nut rotor by using the first safety pin, so that the two half-cut load nut rotors can be tightly combined. When the first safety pin is opened, the load nut rotor can be opened and closed with the upper cover and the lower cover. When the load nut rotor is closed, the arc-shaped enveloping fixture is fixed with the corresponding safety pin combination hole on the combination disc by using the first safety pin. After the first safety pin and the second safety pin in the open-and-close nut structure are pulled out, the open-and-close nut structure can be opened, so that the open-and-close nut structure can be opened at an angle and combined with the descending screw. After the combination is completed, the arc-shaped covering clamp on the load-bearing nut rotor combined with the disc is adjusted to a closed position and the first safety pin is inserted to fix it; at the same time, the upper and lower cover movable end coupling pieces are pushed back to the closed position and fixed with the second safety pin, so that the present invention is easy to operate when in use.

[0018] Furthermore, since the descending screw can be formed into a descending screw of any length using screw splicing technology, a stable and safe descending speed can be achieved by optimizing the thread design including: thread shape type, lead, pitch, surface roughness, etc.

[0019] Furthermore, since the nut stop pin keeps the open and close nut structure for rappelling in a stationary state before the rappelling preparation action is completed, a nut stop plug hole can be set at the screw position corresponding to each floor, so that the present invention allows multiple people from different floors to escape at the same time, and the escapees on different floors can directly use the open and close nut structure for rappelling to escape quickly; after the escapees are ready to rappel, they can pull out the nut stop pin and start rappelling. When rappelling, multiple people can directly get on the screw from different floors. In case of congestion, they only need to hold the screw under the load nut rotor with both hands to achieve the effect of deceleration or stopping, or they can step on the open and close nut mechanism of others below to avoid collision, and continue rappelling after the congestion is relieved. In addition to being affected by hardware parameters, the rappelling speed can also be adjusted by the escapees as needed, including holding the screw with hands or clamping the screw with feet to increase friction.

[0039] After pulling out the second safety pin 90 and the two first safety pins 46, the rappelling open and close nut structure 20 can be opened so that the rappelling open and close nut structure 20 is opened at an angle to combine with the rappelling screw rod 10. After the combination is completed, the movable end coupling member 70 is pushed back to its original position to close it and fixed with the second safety pin 90.

[0040] like Figure 8 As shown, in addition to being fixed by a screw top seat 97 and a screw base 98 at the top and bottom ends of the vertical screw rod 10, a plurality of one-way opening and closing elastic U-shaped clips 96 are arranged at height intervals to stabilize the vertical screw rod 10. When the one-way opening and closing elastic U-shaped clip 96 is in a normal state, the one-way opening and closing elastic U-shaped clip 96 clamps the vertical screw rod 10. When the escapee slides down, the one-way opening and closing elastic U-shaped clip 96 is forced to bend downward and leave the vertical screw rod 10. After the escapee passes, the one-way opening and closing elastic U-shaped clip 96 returns to its original position under the action of elastic force to keep the vertical screw rod 10 stable. In a normal state, the one-way opening and closing elastic U-shaped clip 96 is perpendicular to the vertical screw rod 10 and is arranged alternately in multiple directions, such as the one-way opening and closing elastic U-shaped clip 96 is back to the wall, the one-way opening and closing elastic U-shaped clip 96 is parallel to the wall to the right, and the one-way opening and closing elastic U-shaped clip 96 is parallel to the wall to the left. Furthermore, a base buffer pad 99 may be provided to wrap the screw base 98 to play a buffering role.

[0041] like Fig. 9 As shown, the drop screw 10 can be formed into drop screws 10 of any length through segmented splicing technology for use on floors of different heights, wherein a concentric hole 16 is drilled on the cross-sections at both ends of the drop screw 10 to be spliced ​​as a splicing column 17 accommodating space, and a corresponding solid round rod splicing column 17 is inserted into the accommodating space to complete the splicing of the upper and lower sections of the drop screw 10; in addition, in order to ensure that the external threads 11 on the drop screw 10 can be perfectly aligned, a thread positioning hole 18 is set at the relative position between the cross-sections at both ends of the drop screw 10 and the threads, and the corresponding positioning column 19 is used to accurately position the upper and lower sections of the drop screw 10, so that the load nut rotor 40 can move smoothly on the drop screw 10 that has been fully spliced.

[0042] Therefore, when the high-rise building vertical escape device 100 is hung with a load to escape, the vertical descending screw 10 is passed through the center of the vertical descending open and close nut structure 20 and rotates and slides down according to its external thread 11 to form a slow descent. During the slow descent, the load nut rotor 40 rotates to allow the multiple outer ring thrust rollers 301, multiple inner ring thrust rollers 302, and multiple middle ring thrust rollers 501 on the fixed positions of the upper cover 30 and the lower cover 50 to rotate in the outer ring guide groove 421, the inner ring guide groove 422, and the middle ring guide groove 42 3, but will not drive the upper cover 30 and the lower cover 50 to rotate. The plurality of support columns 38 fix the spacing between the upper cover 30 and the lower cover 50 to improve the deformation strength. The arc-shaped covering clamp 45 strictly limits the opening and closing of the load nut rotor 40. The two first safety latches 46 and the second safety latch 90 control the opening and closing of the load nut rotor 40, the upper cover 30 and the lower cover 50, so that the high-rise vertical escape device 100 can stably hang the escapee to vertically descend.

[0043] Among them, the nut stop pin 15 can prevent the open and close nut structure 20 for rappelling from slowly descending. After the nut stop pin 15 is removed, the open and close nut structure 20 for rappelling can rotate and slide down according to its external thread 11 to form a slow descent, so that the upper cover hanging ring 36 and the lower cover hanging ring 56 on the upper cover 30 and the lower cover 50 can hang the escape wearable device 95, such as: an escape jacket.

[0044] Among them, a fixed pulley 102 and a fireproof pull rope 103 are arranged at the escape exit of the high floor. After rappelling, the rappelling open and close nut structure 20 and the escape jacket 95 can be manually transferred to the required floor for reuse through the fixed pulley 102 and the fireproof pull rope 103.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the description and drawings of the present invention are included in the protection scope of the present invention.
