The linkage system 13 and the traction system 12 are connected in a linkage interlocking mode, and the linkage system 13 is fixedly connected with the escape compartment 14. Here, linkage system 13 and traction system 12 may be interlocked such that escape compartment 14 to which linkage system 13 is coupled descends as traction system 12 descends. Linkage system 13 and traction system 12 may also be unlocked to separate linkage system 13 from traction system 12, thereby separating escape compartment 14 from traction system 12 for individual lowering of escape compartment 14.

Escape compartment 14 is connected to traction system 12 via a reserve rope, and an escape door for an evacuee to enter and exit is provided on escape compartment 14. Here, one end of the reserve rope may be fixed to traction system 12 and the other end may be fixed to escape compartment 14, so that escape compartment 14 may be moved away from traction system 12 by the reserve rope to effect individual lowering of escape compartment 14. In addition, the doors of escape compartment 14 may be provided at the side, top, bottom, etc. of escape compartment 14, and may be determined according to the installation position of the safety escape lifting device.

In use, evacuation module 14 obtains a start signal, generates a descent control signal based on the start signal, and transmits the descent control signal to traction system 12 to cause traction system 12 to control the ascent or descent of evacuation module 14 via linkage system 13 using the traction rope.

Escape compartment 14 is also configured to send a separation signal to traction system 12 to control the unlocking separation of traction system 12 from linkage system 13, and escape compartment 14 is raised or lowered by a reserve rope.

Alternatively, referring to the schematic structure of the safety escape lifting device shown in fig. 2, the fixing bracket 11 of this embodiment may be fixed in a building, such as an indoor roof, an indoor side wall, an indoor floor, etc., and one end of the fixing bracket 11 may extend out of a door or window of the building for suspending the traction system 12, the linkage system 13, and the escape compartment 14. Here, the fixing bracket 11 is fixed on the indoor roof of the building, so that the fire safety escape device can be fixed indoors without affecting the outer vertical surface of the building, and the safety escape lifting device is not required to be adjusted and fixed during use; and the escape device does not need to be fixed on the ground, does not influence the ground movement, and is convenient for people to escape quickly.

In addition, the volume of the safety escape lifting device 1 is reduced, the escape compartment 14 can be arranged in a compressible form, and when the safety escape lifting device is not needed to be used, the escape compartment 14 can be compressed, so that the volume of the escape compartment 14 is reduced; when needed, escape compartment 14 is unfolded and then used. As shown in fig. 2, escape compartment 14 in fig. 2 is in a compressed state.

The fixing bracket 11 may include a guide rail 111 and a prefabricated rigid frame 112, the prefabricated steel frame 112 may be fixed on an indoor roof of a building, the guide rail 111 is disposed between the prefabricated steel frame 112 and the traction system 12, the guide rail 111 is movably fixed on the prefabricated steel frame 112, and the traction system 12 is connected with the guide rail 111 through a traction rope.

The prefabricated steel structure 112 may be connected to a building through a plurality of fixing points, and may be specifically shown in fig. 2, where a black strip between the prefabricated steel structure 112 and the indoor roof in fig. 2 represents a fixing point. The fixed support 11 can be used for reinforcing the door and window of the building by triangle assistance, and can be arranged at the beam of the building or the frame of the door frame, so that enough support is ensured.

Here, it is also possible to provide a smoke alarm on the indoor roof or the fixed support 11 or to associate a safety escape lifting device with the smoke alarm. When the smoke alarm detects smoke or alarms, the guide rail 111 can automatically move the traction system 12, the linkage system 13 and the escape carriage 14 out of the doors and windows of the building, and unfold the escape carriage 14, so that the time of pre-starting is reduced, and escape of the evacuee is facilitated.

Alternatively, escape compartment 14 of the present embodiment may include a compartment body and a safety line; one end of the safety rope is fixed in the carriage body, and the safety rope is used for manually descending. When the safety rope is used, the other end of the safety rope can extend out through the door of the escape compartment 14 to reach the ground, so that escape personnel can conveniently descend through the safety rope.

Here, the safety rope is mainly used under the condition that the traction rope and the standby rope can not descend, so that safety guarantee is provided for the evacuee in the escape box 14, and the evacuee is prevented from being trapped in the escape box 14.

A fixing ring can be arranged in the escape compartment 14, and the safety rope can be placed in a storage box or a storage drawer of the escape compartment 14 when not in use, and then is fixed on the fixing ring when in use, so as to be manually lowered. Correspondingly, auxiliary equipment of safety ropes, such as safety belts, rope drop gloves and the like, can also be arranged in the escape compartment 14.

Optionally, oxygen equipment, medical supplies, drinking water and the like can be arranged in the escape compartment 14, so that the evacuee can conveniently calm the tension, and can perform simple self-help and the like.

According to the embodiment of the invention, the fixing support, the traction system, the linkage system and the escape carriage are arranged in the safe escape lifting device, so that the fixing support is fixed on a building, and the safe escape lifting device can be fixed on the building without adjustment and fixation during use; the escape device does not need to be fixed on the ground, does not influence the ground movement, and is convenient for people to escape quickly; the traction system is connected with the fixed support through the traction rope, when the traction system receives the descending control signal, the traction rope can be used for realizing the electric ascending and descending of the escape compartment, the manual control is not needed, and the situation of operation errors caused by the emotional tension of the evacuee is reduced; the linkage system is connected with the traction system in a linkage interlocking mode, the linkage system is fixedly connected with the escape compartment, when the traction system receives a separation signal, the traction system and the linkage system can be separated, when the traction system has faults or insufficient power and other unusable conditions, the escape compartment can be independently lifted or lowered through the standby rope, the situation that the lifting device cannot be used due to the faults of the traction system is avoided, the usability of the lifting device is improved, and the safety of escape personnel is improved.

In some embodiments, referring to the schematic structural view of another safety escape lifting device shown in fig. 3, the safety escape lifting device 1 may further include a base 15 disposed at the bottom of the escape compartment 14, the base 15 including a pressure sensor.

The pressure sensor is used for detecting pressure data at the bottom of the escape compartment 14 and transmitting the pressure data to the escape compartment 14; escape compartment 14 is also configured to generate a stop control signal based on the pressure data and transmit the stop control signal to traction system 12; traction system 12 controls escape compartment 14 to stop ascending or descending through linkage system 13 according to the stop control signal.

In this embodiment, when evacuation compartment 14 is suspended in the sky and evacuation compartment 14 reaches the ground, pressure sensor 151 will detect different pressure data and transmit it to evacuation compartment 14. Escape compartment 14 may determine from the pressure data that: when the change in pressure data exceeds a preset change threshold, or when the pressure data reaches a preset pressure value, it may be determined that escape compartment 14 and base 15 have reached the ground without further descent, at which point escape compartment 14 may generate a stop control signal and transmit to traction system 12 to stop the release of the traction rope, thereby stopping descent of escape compartment 14.

In addition, escape compartment 14 may also receive an externally input stop command, generate a stop control signal based on the stop command, and transmit to traction system 12 to stop raising or lowering escape compartment 14. Here, a stop button may be provided in escape compartment 14, and an evacuee in escape compartment 14 may press the stop button to stop the ascent or descent of escape compartment 14. A remote controller corresponding to the escape compartment 14 can also be arranged, and a stop button can be arranged on the remote controller, so that after the safe escape lifting device is installed, tried or used, the stop control on the ascending or descending of the escape compartment 14 can be realized through the stop button on the remote controller.

Optionally, the base 15 of the present embodiment further includes a buffer structure; the buffer structure is used for buffering when escape compartment 14 is in contact with the ground.

In this embodiment, the buffer structure can buffer the impact of the escape compartment 14 contacting the ground, so as to provide safety protection for the escape compartment 14 and the evacuees in the escape compartment 14, and reduce the risk of injury to the evacuees.

In some embodiments, escape compartment 14 includes a compartment 141 and a weight control device; the weight controller is used for receiving the starting signal, weighing the carriage 141 according to the starting signal to obtain a weight signal, and transmitting the weight signal to the escape carriage 14; escape compartment 14 is also configured to generate a descent control signal based on the weight signal and transmit the descent control signal to traction system 12.

In this embodiment, escape compartment 14 may receive an externally input activation signal and transmit the activation signal to weight controller to cause weight controller to begin weighing body 141 and transmit the generated weight signal to escape compartment 14 so that escape compartment 14 determines a descent control signal and makes a safe descent.

Here, a start button may be disposed in the escape compartment 14, and an evacuee in the escape compartment 14 may press the start button to generate a start signal, so that the escape compartment 14 receives an externally input start signal, thereby realizing a start control of the ascent or descent of the escape compartment 14.

Wherein the weight signals obtained by evacuation compartment 14 are different, the descent control signals generated by evacuation compartment 14 are different, so as to ensure that the descent speed of evacuation compartment 14 can be within a safe range. For example, the weight is 0-120 kg, the corresponding drop control signal may be first gear, the weight is 120 kg to 240 kg, the corresponding drop control signal may be second gear, the weight is 240 kg to 480 kg, and the corresponding drop control signal may be third gear.

In other embodiments, escape compartment 14 includes a compartment 141 and a weight control device; the weight controller is used for weighing the carriage 141 to obtain a weight signal and transmitting the weight signal to the escape carriage 14; escape compartment 14 determines whether the weight signal has changed for a predetermined period of time and generates a start signal when the weight signal does not change for the predetermined period of time, generates a descent control signal based on the start signal and its corresponding weight signal, and transmits the descent control signal to traction system 12.

In this embodiment, the weight controller may continuously weigh the carriage 141 to obtain the weight signal. The escape compartment 14 can judge the received weight signal, when the weight signal does not change within the preset time, it indicates that the evacuee has all entered the compartment 141 and has remained stable, and can start descending, so the escape compartment 14 can generate a starting signal and further generate a descending control signal to perform safe descending, thereby preventing the evacuee from being too stressed, and further improving the safety of the evacuee under the condition that the delay caused by not pressing the starting button can not descend.

In some embodiments, escape compartment 14 may also include a height gauge; the height gauge is used for measuring the height data between the escape compartment 14 and the ground and generating the height data to the escape compartment 14; escape compartment 14 is configured to receive the height data transmitted from the height gauge and determine whether the received height data is the same for a predetermined number of consecutive times; if the number of the heights of the continuous preset number of times is the same, a separation signal is generated and sent to the traction system 12 so as to unlock and separate the traction system 12 from the linkage system 13.

In this embodiment, the height measuring instrument can measure the height data between the escape compartment 14 and the ground, and if the number of the continuous preset number of times is the same, which indicates that the escape compartment 14 is located at the height for a long time, that is, the escape compartment 14 stops in mid-air and does not descend, the traction system 12 and the traction rope may malfunction, and the escape compartment 14 cannot be controlled to descend any more, so that a separation signal can be generated to unlock and separate the traction system 12 from the linkage system 13. So that escape compartment 14 may be lowered independently from traction system 12 using a pre-set reserve line.

Referring to the schematic of the traction system and linkage system interlock configuration shown in fig. 4, traction system 12 includes a power source, an intermediate relay, a traction motor, a de-pinning motor, and a first linkage 121. The first linkage 121 is connected to the off-pin motor via a first spring and a first off-pin string. The pin removing motor pulls the first pin removing rope upwards to drive the first spring to move, so that the first linkage structure 121 rotates, and the first linkage structure 121 and the linkage system 13 are unlocked and separated.

In some embodiments, the power source is connected to the traction motor through an intermediate relay; the traction motor is connected with the fixed bracket 11 through a traction rope; the power supply is connected with the out-of-stock motor through the intermediate relay; the pin removal motor is connected with the first linkage structure 121, and the first linkage structure 121 is connected with the linkage system 13 in a linkage interlocking mode; the power supply is used for providing power for the traction motor so as to enable the traction motor, the linkage system 13 and the escape compartment 14 to ascend or descend through the traction rope; the power supply is also used for providing power for the pin-out motor when receiving the separation signal sent by the escape compartment 14, so that the pin-out motor controls the first linkage structure 121 to carry out linkage interlocking or unlocking separation with the linkage system 13.

In this embodiment, the power source may power the traction motor and the out-of-stock motor.

When the power supply provides power for the traction motor, the traction rope can be driven to release, so that the traction system 12 descends, and the escape compartment 14 is driven to descend through the linkage system 13.

When the power supply receives the separation signal, the power supply can provide power for the pin removal motor, so that the pin removal motor controls the first linkage structure 121 to rotate, and the unlocking separation of the first linkage structure 121 and the linkage system 13 is realized, so that the subsequent escape carriage 14 can independently descend.

In other embodiments, traction system 12 also includes a thermal overload protector; the power supply is connected with the traction motor through a normally open contact of the intermediate relay and the thermal overload protector; the traction motor is connected with the fixed bracket 11 through a traction rope; the power supply is connected with the pin-out motor through a normally closed contact of the intermediate relay; the pin removal motor is connected with the first linkage structure 121, and the first linkage structure 121 is connected with the linkage system 13 in a linkage interlocking mode; the power supply is used for providing power for the traction motor so as to enable the traction motor, the linkage system 13 and the escape compartment 14 to ascend or descend through the traction rope; the thermal overload protector is used for providing thermal overload protection; the power supply is used for providing power for the pin-out motor when the thermal overload protector acts; the pin-off motor is connected with the first linkage structure 121 and is used for controlling the first linkage structure 121 to rotate so as to enable the first linkage structure 121 to be in linkage interlocking or unlocking separation with the linkage system 13.

In the embodiment, the cooperation of the intermediate relay and the thermal overload protector can realize that the power supply is changed from providing power for the traction motor to providing power for the out-of-stock motor.

Here, when the traction rope or the traction motor fails, the current is excessively large, so that the thermal overload protector is triggered to act, the power supply of the traction motor is cut off, the power supply is turned to provide power for the pin removal motor, the pin removal motor pulls the first pin removal rope upwards to drive the spring to move, and the first linkage structure 121 is rotated, so that the unlocking separation of the first linkage structure 121 and the linkage system 13 is realized.

In addition, a warning alarm and/or a voice prompt may be provided in escape compartment 14, and after the separation signal is generated in escape compartment 14 or after first linkage 121 is unlocked and separated from linkage system 13, the warning alarm and/or the voice prompt in escape compartment 14 may be prompted and broadcast to prompt the evacuee in escape compartment 14. For example, "equipment failure, please pull the manual tab for descent", "equipment failure will be disengaged for descent", "please stand steady", etc. may be prompted.

In some embodiments, referring to the schematic illustration of manual pull tab control rotation of the second linkage shown in fig. 5, escape compartment 14 further includes a manual pull tab 142; the linkage system 13 includes a second linkage structure 131 and a rotational structure 132; the second linkage structure 131 is connected with the first linkage structure 121 in a linkage interlocking manner; the second linkage structure 131 is rotationally connected with the carriage 141 through the rotating structure 132; the manual pull ring 142 is connected with the second linkage structure 131, and the manual pull ring 142 is used for controlling the second linkage structure 131 to rotate so as to carry out linkage interlocking or unlocking separation on the second linkage structure 131 and the first linkage structure 121.

In this embodiment, second linkage 131 in linkage 13 is coupled in a linkage interlock with first linkage 121 in traction system 12, and manual pull tab 142 within escape compartment 14 is coupled to second linkage 131 by further including a second spring and a second de-pinning rope. The manual pull ring 142 pulls the second pin removing rope downwards to drive the second spring to move, so that the second linkage structure 131 rotates, and unlocking and separating of the second linkage structure 131 and the first linkage structure 121 are achieved.

Optionally, manual pull ring 142 may also be connected to traction system 12 via a reserve line, allowing an evacuee in evacuation compartment 14 to lower evacuation compartment 14 by pulling manual pull ring 142 to release the reserve line.
