Description

Technical Field

[0001] This utility model relates to the field of fire escape technology, specifically a double-rope rapid descent high-rise fire escape device. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are springing up like mushrooms after rain. However, while high-rise buildings bring efficient use of space, they also face severe fire safety challenges. In the event of a fire, due to the rapid spread of fire and smoke, traditional stairwell escape routes are easily blocked by dense smoke and flames, leading to people being trapped.

[0003] Currently, escape methods for high-rise fires mainly include fire ladder rescue and escape descent devices. Fire ladders are limited by height, making them unsuitable for the rescue needs of super high-rise buildings. Traditional escape descent devices suffer from problems such as difficulty in controlling speed and low safety, and are also difficult for people with mobility impairments to use. Furthermore, some escape devices lack effective deceleration and protection mechanisms, which can easily cause injury due to excessive speed during descent, compromising the safety of personnel. Therefore, developing a safe, reliable, easy-to-operate, and effectively controllable high-rise fire escape device is of significant practical importance. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a double-rope rapid descent high-rise fire escape device. The technical solution adopted is as follows: it includes a mounting base and two steel wire ropes. The mounting base is U-shaped. Four pulleys are rotatably installed in the grooves at both ends of the mounting base. The four pulleys are in contact with the two steel wire ropes respectively. Anchors are provided at both ends of the steel wire ropes. A load-bearing mechanism and a deceleration mechanism are installed at the top inside the mounting base.

[0005] The supporting mechanism includes a fixed base, a carabiner, a fixing strap, and an escape bladder. The fixed base is U-shaped and has ring-shaped ends. The fixed base is fixedly installed on the top of the mounting base. A carabiner is connected to the ring-shaped portion at both ends of the fixed base. There are four fixing straps. The upper ends of the four fixing straps are fixedly connected to two carabiners respectively, and the lower ends of the four fixing straps are fixedly connected to the sides of both ends of the escape bladder.

[0006] The reduction mechanism includes a drive gear, a transmission gear, and a centrifugal reducer. The drive gear is rotatably mounted on the inner side of one end of the mounting base. The shaft on the end face of the drive gear passes through a through hole on the mounting base and is fixedly connected to the middle of the end face of one of the pulleys. The transmission gear rotates on the inner side of the mounting base and meshes with the drive gear. A centrifugal reducer that cooperates with the transmission gear is fixedly mounted on the top of the mounting base.

[0007] As a preferred embodiment of this utility model, the centrifugal reducer includes a fixed ring and a fixed column. The fixed ring is fixedly installed at the top of the mounting base. A friction ring is fixedly installed on the inner side of the fixed ring. The fixed column is fixedly installed in the middle of the end face of the transmission gear. Several guide rods are fixedly installed on the side of the fixed column. A friction block is slidably installed on each guide rod. A spring is sleeved on the outer side of each guide rod. The two ends of the spring are fixedly connected to the side of the fixed column and the end face of the friction block, respectively. The friction block cooperates with the friction ring.

[0008] As a preferred embodiment of this utility model, the bottom of the escape bag is fixedly connected to one end of two storage straps, and Velcro is fixedly installed on the sides of the two storage straps. A fixing Velcro that cooperates with the Velcro is fixedly installed on the side of the mounting base.

[0009] As a preferred embodiment of this utility model, the sides of one end of the two steel wire ropes are fixedly connected to one end of the fixing rod, the top of the mounting base is fixedly connected to one end of the fixing rope, and the middle part of the fixing rope is tied to the fixing rod by a slip knot.

[0010] As a preferred embodiment of this utility model, a rubber ring is fixedly installed in the arc-shaped groove on the side of the pulley.

[0011] As a preferred technical solution of this utility model, the escape bag is a fire-resistant aramid cloth bag.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model, through the combination of double steel wire cables and pulleys on the mounting base, can evenly distribute the force during the escape process, reduce friction between the steel wire cables and the mounting base, and ensure the stability of the descent. The anchors at both ends of the steel wire cables can be firmly fixed to the building, providing reliable support for the entire escape process and effectively avoiding safety hazards caused by loose connections. Four fixing straps securely connect the escape bag to the mounting base, evenly distributing the body weight and improving user comfort. Through the coordinated operation of the drive gear, transmission gear, and centrifugal reducer in the deceleration mechanism, automatic control of the descent speed is achieved, ensuring that the escapee descends at a safe and appropriate speed, avoiding danger caused by excessive speed.

[0013] 2. When the mounting base descends, the pulley drives the drive gear to rotate. The drive gear meshes with the transmission gear, which in turn rotates the fixed column of the centrifugal reducer. As the rotational speed increases, the centrifugal force causes the friction block on the guide rod to overcome the spring force and slide outward, contacting the friction ring on the inner side of the fixed ring and generating friction, thereby achieving the deceleration function. With the cooperation of the storage strap and Velcro, the escape bladder can be easily stored in the mounting base when not in use, saving space and facilitating storage and management.

[0014] 3. The mounting base is positioned by a fixed rope, which facilitates its release in emergencies. The operation is simple and highly reliable. The rubber ring further increases the friction between the pulley and the steel wire rope, preventing the pulley from slipping and improving the safety and reliability of the device. The escape bag is made of fire-resistant aramid fabric, which has good fire resistance and can provide effective protection for escapees in a fire environment, reducing the risk of burns from flames.

Detailed Implementation

[0022] Example 1

[0023] like Figures 1 to 6As shown, this utility model discloses a double-rope rapid descent high-rise fire escape device. The technical solution includes a mounting base 1 and two steel wire cables 2. The mounting base 1 is U-shaped, and four pulleys 4 are rotatably mounted in the grooves at both ends of the mounting base 1. The four pulleys 4 respectively contact the two steel wire cables 2. Rubber rings 12 are fixedly installed in the arc-shaped grooves on the sides of the pulleys 4. The rubber rings 12 further increase the friction between the pulleys 4 and the steel wire cables 2, preventing slippage of the pulleys 4 and improving the safety and reliability of the device. Anchors 3 are provided at both ends of the steel wire cables 2. One side of the mounting base 1 is fixedly connected to one end of the fixed rod 10, and the top of the mounting base 1 is fixedly connected to one end of the fixed rope 11. The middle of the fixed rope 11 is tied to the fixed rod 10 through a slip knot. The mounting base 1 is positioned by the fixed rope 11, which facilitates the release of the mounting base 1 in an emergency. The operation is simple and highly reliable. The top of the mounting base 1 is equipped with a load-bearing mechanism 5 and a deceleration mechanism 6. Through the cooperation of the double steel wire rope 2 and the pulleys 4 on the mounting base 1, the eight pulleys 4 can evenly distribute the force during the escape process, reduce the friction between the steel wire rope and the mounting base 1, and ensure the stability of the descent process. The anchors 3 at both ends of the steel wire rope 2 can be firmly fixed to the building, providing reliable support for the entire escape process and effectively avoiding safety hazards caused by loose connections.

[0024] The supporting mechanism 5 includes a mounting base 51, carabiners 52, securing straps 53, and an escape bladder 54. The mounting base 51 is U-shaped with annular ends. The mounting base 51 is fixedly installed on the top of the mounting base 1. Carabiners 52 are connected to the annular portions at both ends of the mounting base 51. There are four securing straps 53. The upper ends of the four securing straps 53 are fixedly connected to two carabiners 52 respectively, and the lower ends of the four securing straps 53 are fixedly connected to the sides of both ends of the escape bladder 54. The bottom of the escape bladder 54 is fixedly connected to one end of two storage straps 7. Magic locks are fixedly installed on the sides of the two storage straps 7. The mounting base 1 has a fixed Velcro 9 that works with the Velcro 8. The storage strap 7 and the Velcro 8 work together to make it easy to store the escape bag 54 in the mounting base 1 when not in use, saving space and making it easy to store and manage. The escape bag 54 is a fire-resistant aramid fabric bag. The escape bag 54 is securely connected to the mounting base 51 by four fixing straps 53, which can evenly distribute the weight of the human body and improve the comfort of use. The escape bag 54 is a fire-resistant aramid fabric bag with good fire resistance and can provide effective protection for escapers in fire environment and reduce the risk of being burned by flames.

[0025] The deceleration mechanism 6 includes a drive gear 61, a transmission gear 62, and a centrifugal reducer 63. The drive gear 61 is rotatably mounted on the inner side of one end of the mounting base 1. The shaft on the end face of the drive gear 61 passes through the through hole on the mounting base 1 and is fixedly connected to the middle of the end face of one of the pulleys 4. The transmission gear 62 rotates on the inner side of the mounting base 1 and meshes with the drive gear 61. The centrifugal reducer 63, which cooperates with the transmission gear 62, is fixedly mounted on the top of the mounting base 1. Through the coordinated work of the drive gear 61, the transmission gear 62, and the centrifugal reducer 63 in the deceleration mechanism 6, the automatic control of the descent speed is realized, ensuring that the escapee descends at a safe and appropriate speed, and avoiding danger caused by excessive speed.

[0026] The centrifugal reducer 63 includes a fixed ring 631 and a fixed column 634. The fixed ring 631 is fixedly installed on the top of the mounting base 1. A friction ring 632 is fixedly installed on the inner side of the fixed ring 631. The fixed column 634 is fixedly installed in the middle of the end face of the transmission gear 62. Several guide rods 633 are fixedly installed on the side of the fixed column 634. A friction block 636 is slidably installed on each guide rod 633. A spring 635 is sleeved on the outer side of each guide rod 633. The two ends of the spring 635 are fixedly connected to the side of the fixed column 634 and the end face of the friction block 636, respectively. The friction block 636 cooperates with the friction ring 632. When the mounting base 1 is lowered, the pulley 4 drives the drive gear 61 to rotate. The drive gear 61 meshes with the transmission gear 62, thereby causing the fixed column 634 of the centrifugal reducer 63 to rotate. As the rotational speed increases, the centrifugal force causes the friction block 636 on the guide rod 633 to slide outward against the elastic force of the spring 635, and contact the friction ring 632 on the inner side of the fixed ring 631 to generate friction, thereby realizing the deceleration function.

[0027] The working principle of this utility model is as follows: Anchors 3 at one end of two steel wire cables 2 are fixed to the load-bearing structure (such as concrete beams or walls) of a high-rise building, with the anchor 3 installed perpendicular to the wall surface (e.g., Figure 6As shown), the anchor 3 at the other end is fixed to the load-bearing structure of the adjacent building, and the anchor point is close to the lower platform or ground of the building, keeping the steel cable taut. In case of fire, people can open the storage belt 7, open the escape bag 54, enter the escape bag 54, pull the slip knot of the fixing rope 11 to release the mounting seat 1, and the mounting seat 1 begins to descend along the steel cable 2. At this time, the friction between the pulley 4 and the steel cable 2 will cause the pulley 4 to rotate, making the mounting seat descend stably. At the same time, the rotation of the pulley 4 drives the drive gear 61 to rotate. The drive gear 61 meshes with the transmission gear 62, causing the transmission gear 62 to drive the fixed column 634 of the centrifugal reducer 63 to rotate. The friction block 636 on the guide rod 633 on the side of the fixed column 634 slides outward under the action of centrifugal force, overcoming the elastic force of the spring 635, and contacts the friction ring 632 in the fixed ring 631 to generate friction, realizing automatic deceleration. In this process, the faster the descent speed, the greater the centrifugal force and the stronger the friction, thus controlling the speed within a safe range. During descent, the double steel wire ropes 2, in conjunction with the pulleys 4, evenly distribute the force, while the fixing straps 53 evenly transfer the body weight to the fixing base 51. The fire-resistant aramid fabric escape bladder 54 can withstand flames, and the rubber rings 12 prevent the pulleys 4 from slipping, ensuring the safety of the escapee. After use, the escape bladder 54 is stored in the mounting base 1 using the storage straps 7 and Velcro 8 for easy storage and management.

[0028] In actual use, multiple steel cables 2 can be installed at an angle on the exterior wall of adjacent high-rise buildings. When the fire is large, the mounting base 1 can be removed from the steel cable 2 and placed on other steel cables 2 so that the pulley 4 can contact the steel cable 2, thus achieving continuous rope descent escape.

[0029] The anchor 3 in this utility model can be one of the following: expansion bolt anchor, steel structure anchor, and chemical anchor.

[0030] Components not described in detail in this article are existing technologies.

[0031] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
