Description

Technical Field

[0001] This utility model relates to the technical field of elevator self-rescue and anti-trapped devices, and in particular to an elevator passenger self-rescue and anti-trapped device. Background Technology

[0002] When the elevator's normal power supply fails, the emergency power box can be activated quickly to provide temporary power to the elevator, ensuring that the elevator can run smoothly to the nearest floor and facilitate the safe evacuation of passengers. An elevator passenger self-rescue and anti-trapped device mainly includes a variety of safety devices and emergency measures, thereby ensuring that the elevator can start stably.

[0003] To address this, patent CN214935087U discloses an electric brake release device for elevator power outage rescue. The technical problems this invention aims to solve are inconvenient installation and poor fire resistance and noise reduction performance. To solve these problems, this invention provides an electric brake release device for elevator power outage rescue. This invention mainly consists of an installation mechanism and a protective mechanism. By setting up an installation box, a limiting plate, and a slide rail, it can quickly and securely install the emergency power box and provide a certain buffering capacity, effectively protecting the emergency power box and extending its service life. By setting up a baffle and a vacuum pump, it can create a vacuum environment inside the control cabinet, effectively reducing the noise generated by the electrical components during operation. Furthermore, in the event of spontaneous combustion due to aging electrical components in high-temperature weather, the device, in conjunction with a storage tank and a solenoid valve, can quickly extinguish the fire.

[0004] The electric brake release device for elevator power outage rescue mentioned above uses a threaded rod to drive a buffer plate to install the emergency power box during use. However, the position of the buffer plate needs to be adjusted during installation, which makes installation inconvenient. At the same time, the emergency battery box is buffered by setting a buffer plate and a buffer spring, but there is no damper inside the spring, so the spring cannot absorb energy after being subjected to force, resulting in poor buffering effect.

[0016] The advantages of the elevator passenger self-rescue and anti-trapped device provided by this utility model are as follows:

[0017] By incorporating a buffer structure, the emergency power box is clamped between its two sides by the first damper and the first spring, providing cushioning to the outside of the emergency power box. This also facilitates the installation and disassembly of the emergency power box, reducing installation time for staff. Simultaneously, the elastic deformation of the spring absorbs and dissipates energy, thereby slowing down or preventing the emergency power box from shaking. This achieves shock absorption, buffering, and noise reduction, protecting the emergency power box from damage and extending its service life. The emergency power box can then operate stably and, when passengers are trapped, it can power a distress signal device, allowing passengers to use the device to call for help and enabling rescuers to conduct a rescue, preventing passengers from being trapped in the elevator.

[0018] By incorporating a flame-retardant structure, when the interior of the control cabinet is exposed to high temperatures and an open flame is ignited, a flame sensor detects the flame and sends a signal to start a servo motor. The servo motor then rotates a threaded rod, causing a moving block to move downwards on the outside of the threaded rod via a threaded connection. This, in turn, causes the flame-retardant plate to slide on the outside of a guide rod, thus acting as a limit switch. The flame-retardant plate then moves downwards to block the heat dissipation window, preventing oxygen from entering the internal cavity and intensifying the fire. Simultaneously, the high temperature melts the plastic film, causing the flame retardant inside the mounting box to fall downwards and extinguish the open flame, thus achieving a good flame-retardant effect and protecting personal safety.

The buffer plate 601 is installed on the placement box 4. Inside the box 4, at the bottom of the emergency power supply box 5, support plates 602 are fixed on both sides of the top of the buffer plate 601. The support plates 602 are symmetrically distributed on the top of the buffer plate 601. A first damper 603 is fixed on one side of the support plate 602. A first spring 604 is installed on the outside of the first damper 603. A clamping plate 605 is fixed to one end of the first damper 603. Anti-slip texture is provided on one side of the clamping plate 605. The clamping plate 605 and the support plate 602 form a telescopic structure through the first spring 604. First sliding grooves 606 are provided on both sides inside the box 4. First sliders 607 are fixed on both sides of the buffer plate 601 inside the first sliding grooves 606. A second damper 608 is fixed at the bottom of the buffer plate 601 inside the box 4. The dampers 608 are symmetrically distributed at the bottom end of the buffer plate 601. The top end of the second damper 608 is fixedly connected to the bottom end of the buffer plate 601, and the bottom end of the second damper 608 is fixedly connected to the bottom end of the interior of the placement box 4. A second spring 609 is installed on the outside of the second damper 608. The buffer plate 601 and the placement box 4 form a telescopic structure through the second spring 609. Support seats 610 are fixed at the middle position of the bottom end of the buffer plate 601 at the bottom end of the placement box 4. A third damper 611 is fixed at the top end of the support seat 610. The two ends of the third damper 611 are fixedly connected to one end of the support seat 610. A third spring 612 is installed on the outside of the third damper 611. Hinges 613 are fixed on both sides of the support seat 610. 13 are symmetrically distributed on both sides of the support base 610. The hinge base 613 is equipped with a hinge rod 614. One end of the hinge rod 614 is hinged to the interior of the hinge base 613. A movable rod 615 is installed on one end of the hinge rod 614. The other end of the hinge rod 614 is hinged to one end of the movable rod 615. A moving rod 616 is installed on one end of the movable rod 615. One end of the movable rod 615 is hinged to one end of the moving rod 616. The bottom of the buffer plate 601 is provided with a second slide groove 617 on both sides.

The input end of the distress call device 10 is electrically connected to the output end of the emergency power supply box 5.

[0028] By opening cabinet door 9 and placing emergency power box 5 inside storage box 4, the two sets of clamping plates 605 clamp the sides of emergency power box 5 under the action of first damper 603 and first spring 604. This also provides cushioning to the outside of emergency power box 5, making installation and removal of emergency power box 5 very convenient and reducing installation time for workers. Simultaneously, with emergency power box 5 placed on top of buffer plate 601, buffer plate 601 causes first slider 607 to slide downwards inside first slide groove 606, compressing second spring 609 and third spring 612. This causes hinge rod 614 to drive movable rod 615, which in turn causes moving rod 616 to drive second slider 618 to slide inside second slide groove 617. The elastic deformation of the springs absorbs and dissipates energy, thus slowing down or blocking [the flow of energy]. The emergency power box 5 is designed to prevent shaking, thus achieving shock absorption, buffering, and noise reduction, protecting it from damage and extending its service life. This ensures stable operation and, when passengers are trapped, powers the distress call device 10, allowing them to call for help and receive assistance from rescuers, preventing further elevator entrapment. The distress call device 10 is a wireless communication device comprising a speaker module, a wireless transceiver module, and a microcontroller. When the elevator malfunctions, users can call for help through the speaker module. The audio signal is converted into an electrical signal by a data converter and sent to the microcontroller for processing. The processed data signal is then transmitted to the backend via the wireless transceiver module, enabling self-rescue in case of elevator malfunction.

[0029] Reference Figure 1 , Figure 4 and Figure 5As shown, a heat dissipation window 7 is fixed on one side of the base plate 1. A flame-retardant structure 8 is installed at the top inside the base plate 1. The flame-retardant structure 8 includes a mounting box 801, mounting bolts 802, flame retardant 803, plastic film 804, open flame sensor 805, servo motor 806, first limiting groove 807, threaded rod 808, moving block 809, second limiting groove 810, guide rod 811, connecting block 812, and flame-retardant plate 813. The mounting box 801 is installed at the top inside the built-in cavity 3. Mounting bolts 802 are installed inside the 01 and control cabinet 2. Flame retardant 803 is placed inside the mounting box 801. A plastic film 804 is fixed to one end of the mounting box 801. An open flame sensor 805 is fixed to one side inside the internal cavity 3. A servo motor 806 is fixed to one side of the top of the control cabinet 2. The output end of the open flame sensor 805 is electrically connected to the input end of the servo motor 806. A first limiting groove 807 is provided at the middle position of one side of the internal cavity 3. The first limiting groove 807 has an inner... A threaded rod 808 is installed on the control cabinet 2. The top end of the threaded rod 808 extends through the top end of the first limiting groove 807 to the top end of the control cabinet 2 and is fixedly connected to the output end of the servo motor 806. The bottom end of the threaded rod 808 extends through the bottom end of the first limiting groove 807 to the interior of the control cabinet 2 and is rotatably connected to the interior of the control cabinet 2. A movable block 809 is installed on the outside of the threaded rod 808, and the movable block 809 is threadedly connected to the threaded rod 808. Both sides of the first limiting groove 807 on one side of the internal cavity 3 are... A second limiting groove 810 is provided, which is symmetrically distributed on both sides of the first limiting groove 807. A guide rod 811 is fixed inside the second limiting groove 810, and a connecting block 812 is provided on the outside of the guide rod 811. The connecting block 812 is slidably connected to the outside of the guide rod 811 through a sliding hole. A flame-retardant plate 813 is fixed on one side of the moving block 809 and the connecting block 812. The size of the flame-retardant plate 813 is larger than the size of the heat dissipation window 7. A cabinet door 9 is installed on the other side of the bottom plate 1.

[0030] When the interior of control cabinet 2 is exposed to high temperatures and ignites, the open flame sensor 805 detects the flame and sends a signal to start the servo motor 806. The servo motor 806 drives the threaded rod 808 to rotate, causing the moving block 809 to move downwards on the outside of the threaded rod 808 via a threaded connection. This, in turn, causes the flame-retardant plate 813 to slide on the outside of the guide rod 811, thus acting as a limit switch. The flame-retardant plate 813 moves downwards to block the heat dissipation window 7, preventing oxygen from entering the interior cavity 3 and increasing the fire. At the same time, the high temperature melts the plastic film 804, causing the flame retardant 803 inside the mounting box 801 to fall downwards and extinguish the open flame, thus achieving a good flame-retardant effect and protecting personal safety.
