Description

Technical Field

[0001] This invention relates to the field of lifting device technology, and in particular to a safe escape lifting device. Background Technology

[0002] As buildings continue to develop, their height also increases. High-rise safety escape systems can help people quickly escape a fire and safely reach the ground, ensuring their safety and reducing casualties during a fire. Therefore, high-rise safety escape systems are extremely important.

[0003] In related technologies, safety escape devices or equipment mainly include outdoor rappelling and pre-placed safety passages. While outdoor rappelling and escape ropes are relatively convenient, they are difficult to use and have significant limitations. Escapees need to master the skills to use them, and the elderly and children often find them difficult to use effectively. Pre-placed safety passages have a wider range of applications, but they are primarily suitable for low-rise residential buildings. Furthermore, if a fire occurs on a lower or middle floor, people escaping may face high temperatures and dense smoke.

[0004] Therefore, there is an urgent need for a device that can conveniently and effectively help people escape safely from high-rise buildings. Summary of the Invention

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0048] The inventors have discovered that existing safety escape devices have significant limitations. Outdoor rappelling and escape ropes are difficult to use, requiring escapees to master the necessary skills. Safety passages are primarily suitable for low-rise residential buildings, but may expose escapees to high temperatures and dense smoke. Furthermore, while some safety escape devices can facilitate the evacuation of people from higher floors, these devices are typically integrated units. If the evacuation mechanism malfunctions, it becomes difficult to transport escapees to the ground, potentially trapping them further.

[0049] To improve the convenience of safety escape devices and enhance the safety of escapers, this invention proposes a safety escape lifting device. This device comprises multiple components. After an escaper enters the escape compartment, the device's traction system controls the automatic descent of the compartment, independent of the escaper's own skills. This improves the device's usability and enhances escaper safety. Furthermore, the traction system can be detached from the escape compartment, allowing the compartment to rise or fall independently. This prevents traction system malfunctions that could trap escapers inside the compartment, further improving safety.

[0050] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0051] Figure 1 This is a schematic diagram of a safety escape lifting device provided in an embodiment of the present invention. The safety escape lifting device 1 includes a fixed support 11, a traction system 12, a linkage system 13, and an escape compartment 14.

[0052] The fixed bracket 11 is fixed to the building. The fixed bracket 11 can fix the entire safety escape lifting device in the corresponding position, making it convenient for people inside the building to use.

[0053] The traction system 12 is connected to the fixed bracket 11 via a traction rope. One end of the traction rope can be fixed to the fixed bracket 11, and the other end is fixed and wrapped inside the traction system 12. By releasing the traction rope, the traction system 12 can be lowered.

[0054] The linkage system 13 and the traction system 12 are connected via an interlocking mechanism, and the linkage system 13 is fixedly connected to the escape compartment 14. Here, the linkage system 13 and the traction system 12 can be interlocked, allowing the escape compartment 14 connected to the linkage system 13 to descend as the traction system 12 descends. The linkage system 13 and the traction system 12 can also be unlocked and separated, allowing the escape compartment 14 to descend independently from the traction system 12.

[0055] The escape compartment 14 is connected to the traction system 12 via a spare rope, and has a door for escapees to enter and exit. One end of the spare rope can be fixed to the traction system 12, and the other end to the escape compartment 14, allowing the escape compartment 14 to descend independently away from the traction system 12. Furthermore, the door of the escape compartment 14 can be located on the side, top, or bottom of the escape compartment 14, depending on the installation location of the safety escape lifting device.

[0056] When in use, the escape compartment 14 receives a start signal, generates a descent control signal based on the start signal, and transmits the descent control signal to the traction system 12, so that the traction system 12 uses the traction rope to control the escape compartment 14 to rise or fall through the linkage system 13.

[0057] The escape compartment 14 is also used to send a separation signal to the traction system 12 to control the traction system 12 to unlock and separate from the linkage system 13, and the escape compartment 14 rises or falls by a spare rope.

[0058] Optional, see Figure 2The diagram shows a structural schematic of a fire escape lift fixed indoors. In this embodiment, the fixing bracket 11 can be fixed indoors, such as on the ceiling, side walls, or floor. One end of the fixing bracket 11 can extend to the outside of the building's doors and windows for suspending the traction system 12, the linkage system 13, and the escape compartment 14. Fixing the fixing bracket 11 to the ceiling indoors allows the fire escape device to be fixed indoors without affecting the building's facade. No further adjustment or fixing of the fire escape lift is required during use. Furthermore, it eliminates the need for ground-level fixing, allowing for unimpeded ground movement and facilitating rapid evacuation.

[0059] Furthermore, to reduce the volume of the safety escape lifting device 1, the escape compartment 14 can be made compressible. When not in use, the escape compartment 14 can be compressed to reduce its volume; when needed, it can be unfolded for use. Figure 2 As shown, Figure 2 The escape compartment 14 is in a compressed state.

[0060] The fixed support 11 may include a guide rail 111 and a precast steel frame 112. The precast steel frame 112 can be fixed to the indoor roof of the building. The guide rail 111 is set between the precast steel frame 112 and the traction system 12. The guide rail 111 is movably fixed to the precast steel frame 112. The traction system 12 is connected to the guide rail 111 via a traction rope. Since the guide rail 111 can move on the precast steel frame 112, when the escape chamber 14 is compressed, the traction system 12, the linkage system 13, and the escape chamber 14 can be moved to the indoor area of ​​the building for storage through the guide rail 111, reducing the aging risk of the safety escape lifting device and extending its service life. When needed, the traction system 12, the linkage system 13, and the escape chamber 14 can be moved to the outside of the building's doors and windows through the guide rail 111, and the escape chamber 14 can be unfolded for easy entry and use by evacuees.

[0061] The precast steel structure 112 can be connected to the building and fixed at multiple points, as detailed in the following reference. Figure 2 As shown, Figure 2 The black strip between the precast rigid frame 112 and the interior roof indicates the fixing point. The end of the fixing bracket 11 extending to the outside of the building's doors and windows can be reinforced with a triangular auxiliary reinforcement. It can be set at the roof beam or at the door frame structure, as long as sufficient support is provided.

[0062] Here, smoke detectors can also be installed on the indoor ceiling or on the fixed bracket 11, or the safety escape lifting device can be linked to the smoke detector. When the smoke detector detects smoke or sounds an alarm, the guide rail 111 can automatically move the traction system 12, the linkage system 13 and the escape compartment 14 to the outside of the building's doors and windows, and unfold the escape compartment 14, reducing the pre-start time and facilitating the escape of personnel.

[0063] Optionally, in this embodiment, the escape compartment 14 may include a compartment body and a safety rope; one end of the safety rope is fixed inside the compartment body, and the safety rope is used for manual descent. When using the safety rope, the other end of the safety rope can extend out through the door of the escape compartment 14 to reach the ground, making it convenient for escapees to descend using the safety rope.

[0064] Here, the safety rope is mainly used when it is impossible to descend using the traction rope and the spare rope, to provide safety for the people escaping inside the escape compartment 14 and prevent them from being trapped inside the escape compartment 14.

[0065] The escape compartment 14 can be equipped with a fixing ring. When not in use, the safety rope can be stored in the storage box or drawer of the escape compartment 14. When needed, the safety rope can be secured to the fixing ring for manual descent. Correspondingly, the escape compartment 14 can also be equipped with supporting equipment for the safety rope, such as safety belts and rappelling gloves.

[0066] Optionally, the escape compartment 14 can also be equipped with oxygen equipment, medical supplies and drinking water, to help escapees calm down and perform simple self-rescue.

[0067] In addition, the entire safety escape lift is coated with fire-retardant paint, which can reduce the harm of flames, high temperatures and toxic gases when the escapers are inside the escape compartment 14. The traction rope is protected by silicon titanium fireproof cloth, which can prevent secondary injuries to the escapers when passing through the burning floor during the descent.

[0068] This invention, through the installation of a fixed support, traction system, linkage system, and escape compartment within the safety escape lifting device, secures the device to the building, eliminating the need for further adjustments during use. It also eliminates the need for ground-level fixation, preserving ground movement and facilitating rapid escape. The traction system, connected to the fixed support via a traction rope, allows for electric ascent and descent of the escape compartment upon receiving a descent control signal, eliminating manual control and reducing the risk of errors due to anxiety. The linkage system, interlocked with the traction system and fixedly connected to the escape compartment, allows for separation upon receiving a separation signal. In cases of traction system malfunction or insufficient power, the escape compartment can ascend or descend independently via a spare rope, preventing traction system failure and improving device usability and safety.

[0069] In some embodiments, see Figure 3 The diagram shows another type of safety escape lifting device. The safety escape lifting device 1 may also include a base 15 located at the bottom of the escape compartment 14, and the base 15 includes a pressure sensor.

[0070] The pressure sensor is used to detect the pressure data at the bottom of the escape compartment 14 and transmit the pressure data to the escape compartment 14; the escape compartment 14 is also used to generate a stop control signal based on the pressure data and transmit the stop control signal to the traction system 12; the traction system 12 controls the escape compartment 14 to stop rising or falling through the linkage system 13 according to the stop control signal.

[0071] In this embodiment, when the escape compartment 14 is suspended in mid-air and when it reaches the ground, the pressure sensor 151 detects different pressure data and transmits it to the escape compartment 14. The escape compartment 14 can make a judgment based on the pressure data: when the change in pressure data exceeds a preset change threshold, or when the pressure data reaches a preset pressure value, it can be determined that the escape compartment 14 and the base 15 have reached the ground and no further descent is needed. At this time, the escape compartment 14 can generate a stop control signal and transmit it to the traction system 12 to stop the release of the traction rope, thereby stopping the descent of the escape compartment 14.

[0072] In addition, the escape compartment 14 can receive an externally input stop command, generate a stop control signal based on the stop command, and transmit it to the traction system 12, thereby stopping the escape compartment 14 from rising or falling. A stop button can be installed inside the escape compartment 14, allowing evacuees to press it to stop its ascent or descent. A remote control corresponding to the escape compartment 14 can also be installed, which can also have a stop button. After the safety escape lifting device is installed, tested, or used, the stop button on the remote control can be used to stop the ascent or descent of the escape compartment 14.

[0073] Optionally, the base 15 in this embodiment also includes a buffer structure; the buffer structure is used to buffer when the escape compartment 14 comes into contact with the ground.

[0074] In this embodiment, the buffer structure can cushion the impact when the escape compartment 14 contacts the ground, providing safety protection for the escape compartment 14 and the people inside the escape compartment 14, and reducing the risk of injury to the people inside the escape compartment.

[0075] In some embodiments, the escape compartment 14 includes a compartment 141 and a weight controller; the weight controller is used to receive a start signal, weigh the compartment 141 according to the start signal to obtain a weight signal, and transmit the weight signal to the escape compartment 14; the escape compartment 14 is also used to generate a descent control signal according to the weight signal, and transmit the descent control signal to the traction system 12.

[0076] In this embodiment, the escape compartment 14 can receive an externally input start signal and transmit the start signal to the weight controller so that the weight controller starts to weigh the compartment 141 and transmits the generated weight signal to the escape compartment 14 so that the escape compartment 14 can determine the descent control signal and perform a safe descent.

[0077] Here, a start button can be installed inside the escape compartment 14. The escape personnel inside the escape compartment 14 can press the start button to generate a start signal, so that the escape compartment 14 receives the start signal input from the outside, thereby realizing the start control of the rise or fall of the escape compartment 14.

[0078] The descent control signal generated by the escape compartment 14 will vary depending on the weight signal it receives, ensuring that the descent speed of the escape compartment 14 remains within a safe range. For example, a weight of 0-120 kg corresponds to level one descent control signal, 120 kg to 240 kg corresponds to level two descent control signal, and 240 kg to 480 kg corresponds to level three descent control signal.

[0079] In other embodiments, the escape compartment 14 includes a compartment 141 and a weight controller; the weight controller is used to weigh the compartment 141, obtain a weight signal, and transmit the weight signal to the escape compartment 14; the escape compartment 14 determines whether the weight signal changes within a preset time period, and when the weight signal does not change within the preset time period, generates a start signal, generates a descent control signal based on the start signal and its corresponding weight signal, and transmits the descent control signal to the traction system 12.

[0080] In this embodiment, the weight controller can continuously weigh the escape compartment 141 to obtain a weight signal. The escape compartment 14 can judge the received weight signal. When the weight signal does not change within a preset time, it means that all the escapees have entered the compartment 141 and have stabilized, and can begin to descend. Therefore, the escape compartment 14 can generate a start signal and further generate a descent control signal to ensure a safe descent. This prevents escapees from being too nervous and failing to press the start button, thus delaying descent and further improving the safety of the escapees.

[0081] In some embodiments, the escape compartment 14 may further include a height measuring instrument; the height measuring instrument is used to measure the height data between the escape compartment 14 and the ground, and transmit the height data to the escape compartment 14; the escape compartment 14 is used to receive the height data transmitted by the height measuring instrument, and determine whether the received height data of a consecutive preset number of times is the same; if the height data of a consecutive preset number of times is the same, a separation signal is generated and sent to the traction system 12, so that the traction system 12 and the linkage system 13 are unlocked and separated.

[0082] In this embodiment, the height measuring instrument can measure the height data between the escape compartment 14 and the ground. If the height data is the same for a preset number of consecutive times, it indicates that the escape compartment 14 has been at that height for a long time, meaning that the escape compartment 14 is suspended in mid-air and has not descended. In this case, the traction system 12 and the traction rope may have malfunctioned and cannot control the descent of the escape compartment 14. Therefore, a separation signal can be generated to unlock and separate the traction system 12 from the linkage system 13. This allows the escape compartment 14 to detach from the traction system 12 and descend independently using a pre-set spare rope.

[0083] See Figure 4 The diagram shows the interlocking structure of the traction system and the linkage system. The traction system 12 includes a power supply, an intermediate relay, a traction motor, a release pin motor, and a first linkage structure 121. The first linkage structure 121 is connected to the release pin motor via a first spring and a first release pin rope. The release pin motor pulls the first release pin rope upward, causing the first spring to move, thereby rotating the first linkage structure 121 and unlocking and separating it from the linkage system 13.

[0084] In some embodiments, the power supply is connected to the traction motor via an intermediate relay; the traction motor is connected to the fixed bracket 11 via a traction rope; the power supply is connected to the release pin motor via an intermediate relay; the release pin motor is connected to the first linkage structure 121, and the first linkage structure 121 is connected to the linkage system 13 via a linkage interlock; the power supply is used to provide power to the traction motor so that the traction motor, the linkage system 13, and the escape compartment 14 can be raised or lowered via the traction rope; the power supply is also used to provide power to the release pin motor when a separation signal is received from the escape compartment 14 so that the release pin motor controls the first linkage structure 121 to perform linkage interlocking or unlocking separation with the linkage system 13.

[0085] In this embodiment, the power source can provide power to the traction motor and the decoupling motor.

[0086] When the power source provides power to the traction motor, it can drive the traction rope to release, thereby causing the traction system 12 itself to descend, and driving the escape compartment 14 to descend through the linkage system 13.

[0087] When the power source receives the separation signal, it will provide power to the pin release motor, which will control the first linkage structure 121 to rotate, thereby unlocking and separating the first linkage structure 121 and the linkage system 13, so that the escape compartment 14 can be lowered independently.

[0088] In other embodiments, the traction system 12 further includes a thermal overload protector; the power supply is connected to the traction motor via the normally open contact of the intermediate relay and the thermal overload protector; the traction motor is connected to the fixed bracket 11 via a traction rope; the power supply is connected to the release pin motor via the normally closed contact of the intermediate relay; the release pin motor is connected to the first linkage structure 121, and the first linkage structure 121 is connected to the linkage system 13 via a linkage interlock; the power supply is used to provide power to the traction motor so that the traction motor, the linkage system 13, and the escape compartment 14 can be raised or lowered via the traction rope; the thermal overload protector is used to provide thermal overload protection; the power supply is used to provide power to the release pin motor when the thermal overload protector is activated; the release pin motor is connected to the first linkage structure 121 and is used to control the rotation of the first linkage structure 121 so that the first linkage structure 121 and the linkage system 13 can be interlocked or unlocked.

[0089] In this embodiment, the power supply can be switched from providing power to the traction motor to providing power to the decoupling motor through the cooperation of the intermediate relay and the thermal overload protector.

[0090] Here, when the traction rope or traction motor malfunctions, it will cause excessive current, thereby triggering the thermal overload protector to cut off the power supply to the traction motor and instead supply power to the release pin motor, causing the release pin motor to pull the first release pin rope upward, driving the spring to move, thereby causing the first linkage structure 121 to rotate, realizing the unlocking and separation of the first linkage structure 121 and the linkage system 13.

[0091] In addition, a loudspeaker alarm and / or voice prompts can be installed inside the escape compartment 14. After the escape compartment 14 generates a separation signal, or after the first linkage structure 121 is unlocked and separated from the linkage system 13, the loudspeaker alarm and / or voice prompts inside the escape compartment 14 can provide alerts and announcements to the evacuees inside the escape compartment 14. For example, prompts such as "Equipment malfunction, please pull the manual pull ring to descend" or "Equipment malfunction, detachment and descent will begin, please hold on tight" can be made.

[0092] In some embodiments, see Figure 5 The diagram shown illustrates the manual pull ring controlling the rotation of the second linkage structure. The escape compartment 14 also includes a manual pull ring 142. The linkage system 13 includes a second linkage structure 131 and a rotation structure 132. The second linkage structure 131 is connected to the first linkage structure 121 in a linkage interlocking manner. The second linkage structure 131 is rotatably connected to the compartment 141 through the rotation structure 132. The manual pull ring 142 is connected to the second linkage structure 131 and is used to control the rotation of the second linkage structure 131 so that the second linkage structure 131 and the first linkage structure 121 can be interlocked or unlocked.

[0093] In this embodiment, the second linkage structure 131 in the linkage system 13 is connected to the first linkage structure 121 in the traction system 12 in a linkage interlocking manner. The manual pull ring 142 in the escape compartment 14 is connected to the second linkage structure 131 by means of a second spring and a second release rope. The manual pull ring 142 pulls the second release rope downward, causing the second spring to move, thereby rotating the second linkage structure 131 and unlocking and separating the second linkage structure 131 and the first linkage structure 121.

[0094] Optionally, the manual pull ring 142 can also be connected to the traction system 12 via a spare rope, allowing evacuees inside the escape compartment 14 to release the spare rope by pulling the manual pull ring 142, thus lowering the escape compartment 14.

[0095] Alternatively, the escape compartment 14 can be connected to the traction system 12 via a spare rope, allowing the escape compartment 14 to descend automatically using the weight of the people escaping inside.

[0096] Optionally, the escape compartment 14 may also include a camera and a display. The camera can be used to capture images outside the escape compartment 14, and the display can be used to show the images captured by the camera, allowing the escapers inside the escape compartment 14 to view their current descent position or height and understand the situation outside the escape compartment 14. Additionally, the escapers inside the escape compartment 14 can use the aforementioned display to determine whether the escape compartment 14 has been in the same position for an extended period and to take appropriate action. For example, if the escapers find that the escape compartment 14 has been in the same position for an extended period, they can pull the manual pull ring 142 to unlock and separate the second linkage structure 131 from the first linkage structure 121, allowing the escape compartment 14 to descend independently.

[0097] In order to observe and understand the situation outside the escape compartment 14, observation devices such as peepholes and transparent windows can also be installed.

[0098] This invention, through the installation of a fixed support, traction system, linkage system, and escape compartment within a safety escape lifting device, secures the device to the building, eliminating the need for further adjustments during use. It also eliminates the need for ground-level fixation, preserving ground-level activities and facilitating rapid escape. The fixed support can be installed indoors, without affecting the building's facade, and is convenient for evacuees inside. The traction system connects to the fixed support via a traction rope. When the traction system receives a descent control signal, it electrically raises and lowers the escape compartment, eliminating the need for manual control and reducing the risk of errors due to anxiety. The escape compartment is equipped with a weight controller that detects the weight of the evacuees, generating a descent control signal to initiate a safe and stable descent. Furthermore, the escape compartment can automatically detect and activate the descent, preventing evacuees from being suspended in mid-air for extended periods. The linkage system and traction system are connected via interlocking. The linkage system is fixedly connected to the escape compartment. When the traction system receives a separation signal, the traction system and linkage system can separate. In cases where the traction system malfunctions or has insufficient power, the escape compartment can ascend or descend independently via a spare rope, preventing the lifting device from becoming unusable due to traction system failure, thus improving the availability of the lifting device and enhancing the safety of evacuees. Furthermore, the linkage system can also utilize intermediate relays and thermal overload protectors to provide power to the trip motor in case of traction rope or traction motor failure, allowing the traction system and linkage system to separate. This enables the escape compartment to ascend or descend independently via the spare rope, further enhancing the safety of evacuees.
