Description

Technical Field

[0001] The invention relates to the technical field of escape equipment, in particular to fire escape lifting equipment for teaching buildings. Background Art

[0002] The fire escape equipment in the teaching building includes a variety of lifting equipment, which is mainly used to help people evacuate safely in the event of a fire. Common lifting equipment includes the following: Fire elevators: elevators specially designed for use in fires, with strong fire resistance and dedicated control systems to ensure normal operation and safe access to each floor in the event of a fire; Refuge floors: Some teaching buildings are designed with refuge floors, which are usually equipped with special fire escape equipment, such as fire-resistant stairs and airtight doors, to help people wait for rescue safely in the event of a fire; Escape ladders: such as external folding escape ladders, climbing ladders, etc. These equipment can help people on higher floors escape from the fire; Vertical lifting platforms: Some teaching buildings are equipped with vertical lifting platforms to help people with limited mobility evacuate in the event of a fire.

[0003] The existing fire escape lifting equipment for teaching buildings often adopts the electrical control system of the teaching building or a special control system similar to the fire elevator. The system has a wide control range and is greatly affected by the environment at the fire scene. It is difficult to ensure that there will be no failure, which makes it impossible for people on high floors to evacuate and cannot provide a temporary shelter. In addition, in order to ensure the thermal insulation effect and prevent the injury of falling objects, the existing escape lifting equipment often adopts the form of a sealed compartment to transport the escapees. The high-temperature smoke and dust entering the compartment will make the environment inside the compartment worrying, and will have a negative impact on some injured people, causing their injuries to be more serious.

[0004] To this end, the present invention provides a fire escape lifting device for a teaching building to solve the above problems. Summary of the invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fire escape lifting equipment for a teaching building, comprising a traction slide rail and an escape capsule sliding on one side of the traction slide rail, the escape capsule is provided with two safety doors on one side of the traction slide rail, two air vents are provided on the upper end of the escape capsule away from the traction slide rail, two protective plates are provided in the air vents, two ventilation holes are provided on the same side and below the air vents, fans are rotated at both ventilation holes, an independent power supply box is fixedly provided in the escape capsule, a driving lifting motor is also fixedly provided on the inner wall of the escape capsule, the driving lifting motor drives the safety door setting, and the driving lifting motor and the independent power supply box are electrically connected, the safety door and the protective plate cooperate with each other through a traction mechanism, and the safety door and the fan are correspondingly connected to each other through a sliding power connection mechanism.

[0007] Preferably: the traction rail is buried in a wall on one side of the teaching building, and support frames are welded on both sides of the traction rail, the support frames are arranged in a plurality of triangle shapes, and the wall where the traction rail is located is a stair support wall.

[0008] Preferably, two ventilation plates are fixedly provided on the outer wall of the escape capsule on one side away from the traction rail, and the two ventilation plates are respectively arranged corresponding to the two ventilation openings.

[0009] Preferably: the traction mechanism includes a roller rotatably arranged in the side wall of the escape capsule, an elastic traction rope is connected between the side wall of the protective plate and the side wall of the safety door, the elastic traction rope passes around the side wall of the roller, a second spring is fixedly provided in the upper wall of the vent, the lower end of the second spring and the upper wall of the protective plate are fixed to each other, and a corresponding sliding opening is opened in the side wall of the escape capsule above the safety door for cooperating with the opening process of the safety door.

[0010] Preferably: the sliding power connection mechanism includes a power connection plate fixedly arranged on the inner wall of the upper end of the escape capsule, the power connection plate and the fan are electrically connected, a sliding cavity is correspondingly opened on the side wall of the safety door, a sliding plate slides in the sliding cavity, a first spring is fixedly arranged between the bottom wall of the sliding cavity and the lower wall of the sliding plate, the upper wall of the sliding plate and the lower wall of the power connection plate correspond to each other, and the power connection plate and the sliding plate are spaced apart, the independent power supply box and the sliding plate are electrically connected, and the fan and the independent power supply box are also electrically connected.

[0011] Preferably: thermal insulation plates are fixedly provided on both side walls of the inner wall of the escape capsule, and the safety door is also made of thermal insulation material.

[0012] The present invention provides a fire escape lifting device for a teaching building. Compared with the prior art, it has the following beneficial effects: (1) The fire escape lifting device for the teaching building controls the independent power box through the opening door provided on the side wall of the escape cabin and drives the lifting motor to drive the safety door to move upward, so that personnel can enter the escape cabin through the safety door. In the process of the safety door moving upward and opening, the elastic traction rope drives the roller to rotate and pulls the protective plate downward, so that the vent is opened relative to the outside. When the vent is fully opened, the safety door continues to move upward, and the elastic traction rope continues to extend under the action of its own elasticity. The elastic force of the second spring is smaller than the elastic force brought by the elasticity of the elastic traction rope, thereby ensuring the normal working process of the device. In addition, through the opening process of the vent, the high-temperature smoke and the like that enters the escape cabin after the safety door is opened can be discharged through the vent, thereby preventing the escape cabin from being filled with a large amount of high-temperature smoke in a short time, thereby ensuring the safety of the environment in the escape cabin.

[0013] (2) The fire escape lifting equipment for the teaching building, when the safety door moves upward, the sliding plate provided on the side wall of the safety door moves synchronously with the safety door until the sliding plate and the power plate contact each other. As the safety door continues to move upward, the sliding plate drives the sliding cavity to compress. During the process, the power plate and the sliding plate are always in contact. When the power plate and the sliding plate are in contact, the power provided by the independent power supply box causes the fan to rotate accordingly. In conjunction with the opening process of the protective plate, the high-temperature smoke entering the escape cabin through the door opening can be discharged in time, which increases the gas circulation and replacement in the escape cabin and effectively prevents the condition of some injured persons from further deteriorating.

[0014] (3) The fire escape lifting equipment for the teaching building, after the personnel enter the escape capsule, in the process of closing the safety door, when the safety door begins to descend, the contact plate and the sliding plate continue to be in contact, so that the fan continuously discharges and circulates the gas in the escape capsule until the safety door is about to be completely closed. At this time, the contact between the contact plate and the sliding plate is disengaged, and the fan stops working. At this time, the escape capsule is in a relatively closed state, with only the natural connection at the ventilation port. Under the action of the ventilation plate, external impurities are prevented from entering the escape capsule, ensuring that during the descent of the escape capsule, smoke generated by the building fire will not enter the escape capsule and cause harm to the human body. That is, it prevents excessive high-temperature smoke from entering the escape capsule when the personnel enter, and also realizes the isolation and protection of personnel when they are lifted and transported, greatly improving the safety of the escape equipment.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-8A fire escape lifting device for a teaching building comprises a traction slide rail 2 and an escape capsule 1 sliding on one side of the traction slide rail 2. The escape capsule 1 is provided with two safety doors 7 on one side of the traction slide rail 2. Two vents 4 are provided on the upper end of the escape capsule 1 away from the traction slide rail 2. Two protective plates 5 are provided in the vents 4. Two ventilation holes 11 are provided below the same side of the vents 4. Fans 12 are rotated at the two ventilation holes 11. An independent power supply box 13 is fixedly provided in the escape capsule 1. A driving lifting motor 9 is also fixedly provided on the inner wall of the escape capsule 1. The driving lifting motor 9 drives the safety door 7, and the driving lifting motor 9 and the independent power supply box 13 are electrically connected. The safety door 7 and the protective plate 5 cooperate with each other through a traction mechanism, and the safety door 7 and the fan 12 are correspondingly connected to each other through a sliding power connection mechanism.

[0019] In an optional embodiment: the traction rail 2 is buried in a wall on one side of the teaching building, and support frames 3 are welded on both sides of the traction rail 2, the support frames 3 are arranged in a plurality of triangular shapes, and the wall where the traction rail 2 is located is a stair support wall.

[0020] It should be noted that in the event of a fire, the stability of the wall on this side of the teaching building is guaranteed, providing effective support for the process of transporting personnel.

[0021] In an optional embodiment: two ventilation plates 6 are fixedly provided on the outer wall of the escape capsule 1 on one side away from the traction rail 2, and the two ventilation plates 6 are respectively arranged corresponding to the two ventilation openings 11.

[0022] It should be noted that, under the action of the ventilation plate 6, external impurities are prevented from entering the escape capsule 1, ensuring that during the descent of the escape capsule 1, smoke generated by a building fire will not enter the escape capsule 1 and cause harm to the human body. That is, it prevents excessive high-temperature smoke from entering the escape capsule 1 when personnel enter, and also achieves isolation and protection of personnel when they are lifted and transported, greatly improving the safety of the escape equipment.

[0023] In an optional embodiment: the traction mechanism includes a roller 20 rotatably arranged in the side wall of the escape capsule 1, an elastic traction rope 19 is connected between the side wall of the protective plate 5 and the side wall of the safety door 7, the elastic traction rope 19 passes around the side wall of the roller 20, a second spring 18 is fixed in the upper wall of the vent 4, the lower end of the second spring 18 and the upper wall of the protective plate 5 are fixed to each other, and a corresponding sliding opening 8 is opened on the side wall of the escape capsule 1 above the safety door 7 for cooperating with the opening process of the safety door 7.

[0024] It should be noted that in the process of the safety door 7 moving upward and opening, through the action of the elastic traction rope 19, the safety door 7 moves upward, driving the roller 20 to rotate, and pulling the protective plate 5 downward, so that the vent 4 is opened relative to the outside world. When the vent 4 is fully opened, the safety door 7 continues to move upward, and the elastic traction rope 19 continues to stretch under the action of its own elasticity. The elastic force of the second spring 18 is smaller than the elastic force brought by the elastic traction rope 19 itself, thereby ensuring the normal working process of the device. In addition, through the opening process of the vent 4, the high-temperature flue gas that enters the escape capsule 1 after the safety door 7 is opened can be discharged through the vent 4, thereby avoiding the escape capsule 1 being filled with a large amount of high-temperature flue gas in a short time, thereby ensuring the safety of the environment in the escape capsule 1.

[0025] In an optional embodiment: the sliding power connection mechanism includes a power connection plate 14 fixedly arranged on the inner wall of the upper end of the escape capsule 1, the power connection plate 14 and the fan 12 are electrically connected, a sliding cavity 15 is correspondingly opened at the side wall of the safety door 7, a sliding plate 16 slides in the sliding cavity 15, a first spring 17 is fixedly arranged between the bottom wall of the sliding cavity 15 and the lower wall of the sliding plate 16, the upper wall of the sliding plate 16 and the lower wall of the power connection plate 14 correspond to each other, and the power connection plate 14 and the sliding plate 16 are spaced apart, the independent power supply box 13 and the sliding plate 16 are electrically connected, and the fan 12 and the independent power supply box 13 are also electrically connected.

[0026] It should be noted that, in the process of the safety door 7 moving upward, the sliding piece 16 provided on the side wall of the safety door 7 moves synchronously with the safety door 7 moving upward until the sliding piece 16 and the power plate 14 contact each other. As the safety door 7 continues to move upward, the sliding piece 16 drives the sliding cavity 15 to be compressed. During the process, the power plate 14 and the sliding piece 16 are always in contact. When the power plate 14 and the sliding piece 16 are in contact, the power provided by the independent power supply box 13 causes the fan 12 to rotate accordingly, and cooperates with the opening process of the protective plate 5, so that the high-temperature smoke entering the escape cabin 1 through the door opening can be discharged in time, thereby increasing the gas circulation replacement in the escape cabin 1 and effectively preventing the condition of some injured persons from further deteriorating.

[0027] In an optional embodiment: a thermal insulation plate 10 is fixedly provided on both sides of the inner wall of the escape capsule 1, and the safety door 7 is also made of a thermal insulation material.

[0028] It should be noted that preventing high temperatures from the outside and the floors from entering the escape capsule 1 by transmission ensures that the temperature in the escape capsule 1 is appropriate, and when the escape capsule 1 is used as a temporary shelter, preventing high temperature shock to the personnel in the escape capsule 1.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] When the device is in use, the independent power box 13 is controlled by the opening door provided on the side wall of the escape capsule 1, and the safety door 7 is driven to move upward by driving the lifting motor 9, so that personnel can enter the escape capsule 1 through the safety door 7. In the process of the safety door 7 moving upward and opening, the roller 20 is driven to rotate and the protective plate 5 is pulled downward to open the vent 4 relative to the outside world through the action of the elastic traction rope 19. When the vent 4 is fully opened, the safety door 7 continues to move upward, and the elastic traction rope 19 continues to extend under the action of its own elasticity. The elastic force of the second spring 18 is smaller than the elastic force brought by the elasticity of the elastic traction rope 19, thereby ensuring the normal working process of the device. In addition, through the opening process of the vent 4, the high-temperature smoke and the like entering the escape capsule 1 after the safety door 7 is opened can be discharged through the vent 4, thereby preventing the escape capsule 1 from being filled with a large amount of high-temperature smoke in a short time, thereby ensuring the safety of the environment in the escape capsule 1. At the same time, during the upward movement of the safety door 7, the sliding sheet 16 provided on the side wall of the safety door 7 moves synchronously with the upward movement of the safety door 7 until the sliding sheet 16 and the power sheet 14 contact each other. As the safety door 7 continues to move upward, the sliding sheet 16 drives the sliding cavity 15 to be compressed. During the process, the power sheet 14 and the sliding sheet 16 are always in contact. When the power sheet 14 and the sliding sheet 16 are in contact, the power provided by the independent power supply box 13 causes the fan 12 to rotate accordingly, and cooperates with the opening process of the protective plate 5, so that the high-temperature smoke entering the escape cabin 1 when the door is opened can be discharged in time, thereby increasing the gas circulation replacement in the escape cabin 1 and effectively preventing the condition of some injured persons from further deteriorating. When a person enters the escape capsule 1 and closes the safety door 7, when the safety door 7 begins to descend, the power strip 14 and the sliding piece 16 continue to be in contact, so that the fan 12 continuously discharges and circulates the gas in the escape capsule 1 until the safety door 7 is about to be completely closed. At this time, the contact between the power strip 14 and the sliding piece 16 is disengaged, and the fan 12 stops working. At this time, the escape capsule 1 is in a relatively closed state, with only the natural connection at the vent 11. Under the action of the ventilation plate 6, external impurities are prevented from entering the escape capsule 1, ensuring that during the descent of the escape capsule 1, smoke generated by a building fire will not enter the escape capsule 1 to cause harm to the human body, that is, it prevents too much high-temperature smoke from entering the escape capsule 1 when a person enters, and also implements isolation and protection of the personnel when they are lifted and transported, thereby greatly improving the safety of the escape equipment.
