Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator that is fall-proof and highly safe. Background Technology

[0002] Existing fall-proof and highly safe elevators use speed sensors to detect the elevator's descent speed and activate emergency stop components to quickly bring the elevator to a stop when it falls. However, speed sensors are expensive and difficult to repair after damage. For example, a fall-proof elevator device disclosed in Chinese Patent Application No. CN202322907394.6, although it monitors the car's running speed through a speed sensor, and when the running speed increases, the limit plate moves, the tension spring and the drive rod cooperate to make the connecting rod A abut against the brake plate, and the brake plate moves to abut against the elevator shaft wall to brake the descending car and prevent it from falling, has a complex structure, is prone to damage and becomes unusable, and cannot protect the people inside the elevator during an emergency stop, thus limiting its use. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an elevator that is fall-proof and highly safe. When the elevator falls, the pressure block in the fixed cylinder moves the sliding plate downward under the action of gravity, and pulls the limiting block to release the restriction effect on the friction plate. The spring pushes the friction plate to quickly contact the elevator shaft wall to generate friction and prevent the elevator from falling. At the same time, the sliding plate will also press the igniter, which will ignite the sodium azide inside the gas filling component, causing it to react and produce nitrogen gas, which fills the air cushion. This prevents people from being injured by inertial impact to the top of the elevator when the elevator stops suddenly.

[0004] This utility model also provides an elevator with the above-mentioned anti-fall and high safety features, comprising: an elevator body, a connecting box fixedly connected to the upper surface of the elevator body, a compression spring fixedly connected to the upper surface of the connecting box, a pressure block fixedly connected to the end of the compression spring away from the connecting box, a connecting rod fixedly connected to the lower surface of the pressure block, a sliding plate fixedly connected to the end of the connecting rod away from the pressure block, a rope fixedly connected to the side surface of the sliding plate, and a limit block fixedly connected to the end of the rope away from the sliding plate;

[0005] A fixed plate is fixedly connected to the lower surface of the elevator body. An electromagnet is fixedly connected to the inner side wall of the fixed plate. A slider is slidably connected to the inner side wall of the fixed plate. A sliding rod is fixedly connected to the side surface of the slider. A friction plate is fixedly connected to the end of the sliding rod away from the slider. A thrust spring is fixedly connected to the side surface of the friction plate. The end of the thrust spring away from the sliding rod is fixedly connected to the fixed plate. Using these components, the properties of the spring can be utilized to cause the pressure block to drive the sliding plate to pull the limiting block when the elevator falls, causing the friction plate to quickly pop out and generate friction with the elevator shaft to stop the elevator from falling.

[0006] According to the present invention, an elevator with high safety and fall prevention features a fixed cylinder fixedly connected to the upper surface of the connecting box, and the side surface of the pressure block slidably connected to the fixed cylinder. Through these components, the pressure block can be protected by the fixed cylinder.

[0007] According to the present invention, an elevator with high safety and fall prevention features a pulley rotatably connected to the upper surface of the elevator body, and the side surface of the rope is drivenly connected to the pulley. These components reduce friction during rope movement by using the pulley, thus improving the rope's service life.

[0008] According to the present invention, an elevator with high safety and fall prevention features a sliding groove plate fixedly connected to the side surface of the elevator body, and a limiting block slidably connected to the side surface of the sliding groove plate. Through these components, the sliding groove plate effectively fixes and limits the limiting block.

[0009] According to the present invention, an elevator with anti-fall and high safety features is provided, wherein the side surface of the sliding rod is slidably connected to an electromagnet, and the side surface of the slider is in contact with the electromagnet during operation. Through these components, the electromagnet can hold the slider in place, preventing the friction plate from retracting during use.

[0010] According to the present invention, an elevator with high safety and fall prevention features a storage box fixedly connected to the upper top wall of the elevator body, and an inflation component fixedly connected inside the storage box. The inflation component can be used to inflate an air cushion.

[0011] According to this utility model, an elevator with high safety and fall prevention features an air cushion fixedly connected inside the storage box, located below an inflatable component. This component allows the air cushion to inflate and cover the upper part of the elevator, preventing occupants from being impacted by inertia and falling onto the elevator top.

[0012] According to the present invention, an elevator with high safety and fall prevention features an igniter fixedly connected to the upper surface of the inflatable component. The end of the igniter away from the inflatable component extends through the top wall of the elevator body into the interior of the connecting box. Through this component, when the sliding plate strikes the igniter, the igniter causes a reaction within the inflatable component, generating nitrogen gas which is then inflated into the air cushion.

[0013] Beneficial effects:

[0014] Compared with existing technologies, when the elevator falls, the pressure block in the fixed cylinder moves the sliding plate downward under the action of gravity, and pulls the limit block to release the restriction on the friction plate. This allows the spring to push the friction plate to quickly contact the elevator shaft wall, generating friction to prevent the elevator from falling. At the same time, the sliding plate will also press the igniter, causing the igniter to ignite the sodium azide inside the gas filling component, causing it to react and produce nitrogen gas, which fills the air cushion. This prevents people from being injured by inertial impact to the top of the elevator when the elevator stops suddenly. Attached Figure Description

[0024] A fixing plate 8 is fixedly connected to the lower surface of the elevator body 1 to protect the internal electromagnet 19 and slider 21. An electromagnet 19 is fixedly connected to the inner side wall of the fixing plate 8 to attract the slider 21 and prevent it from causing the friction plate 9 to retract. A slider 21 is slidably connected to the inner side wall of the fixing plate 8. The side surface of the slider 21 is in contact with the electromagnet 19 during operation; it is a metal block that comes into contact with the electromagnet 19 under the action of the sliding rod 20. Attracted by the electromagnet 19, it prevents the friction plate 9 from retracting when rubbing against the elevator shaft. A slide rod 20 is fixedly connected, and the side surface of the slide rod 20 is slidably connected to the electromagnet 19. The slider 21 is connected to the friction plate 9. The end of the slide rod 20 away from the slider 21 is fixedly connected to the friction plate 9. Under the push of the thrust spring 10, the slide rod 20 is driven to quickly contact the elevator shaft to generate friction and prevent the elevator body 1 from falling. The side surface of the friction plate 9 is fixedly connected to the thrust spring 10. After the limit block 7 is released from the fixed state, the friction plate 9 is quickly pushed to contact the elevator shaft. The end of the thrust spring 10 away from the slide rod 20 is fixedly connected to the fixed plate 8.

[0025] A fixed cylinder 3 is fixedly connected to the upper surface of the connecting box 2 to protect the internal pressure block 13. The side surface of the pressure block 13 is slidably connected to the fixed cylinder 3. A pulley 5 is rotatably connected to the upper surface of the elevator body 1 to reduce the wear of the rope 4 when it slides and improve the service life of the rope 4. The side surface of the rope 4 is connected to the pulley 5 for transmission. A slide plate 6 is fixedly connected to the side surface of the elevator body 1 to fix and limit the limit block 7. The side surface of the limit block 7 is slidably connected to the slide plate 6.

[0026] A storage box 11 is fixedly connected to the upper top wall of the elevator body 1, which holds the inflation component 18 and the air cushion 12. The inflation component 18 is fixedly connected inside the storage box 11 and contains sodium azide. After being ignited by the igniter 17, nitrogen gas is generated and rushes into the air cushion 12. The air cushion 12 is fixedly connected inside the storage box 11 and can be filled with the nitrogen gas generated by the inflation component 18. After expansion, it covers the upper part of the elevator body 1, preventing people inside the elevator body 1 from being injured by impacting the elevator body 1 due to inertia. The air cushion 12 is located below the inflation component 18. The igniter 17 is fixedly connected to the upper surface of the inflation component 18. After being impacted by the slide plate 16, it will ignite the substance inside the inflation component 18. The end of the igniter 17 away from the inflation component 18 extends through the upper top wall of the elevator body 1 and into the interior of the connecting box 2.

[0027] Working principle: When the elevator body 1 falls, the pressure block 13 will drive the connecting rod 15 and the slide plate 16 to compress the spring 14 under the action of inertia. At the same time, the slide plate 16 will pull the limit block 7 through the rope 4 to release the limit state of the friction plate 9. After the fixation is released, the thrust spring 10 will push the friction plate 9 out quickly, so that the friction plate 9 contacts the elevator shaft and generates friction to prevent the elevator from falling. When the friction plate 9 pops out, it will also drive the slider 21 to slide in the fixed plate 8 through the slide rod 20 and contact and attract the electromagnet 19 to prevent the friction plate 9 from not contacting the elevator shaft. After the slide plate 16 moves down, it will also hit the igniter 17, so that the igniter 17 ignites the sodium azide inside the gas filling component 18. After the sodium azide reacts, it will produce a large amount of nitrogen gas and fill the air cushion 12, causing the air cushion 12 to expand. The air cushion 12 covers the upper part of the elevator body 1 to prevent people from hitting the elevator body 1 under the action of inertia when the elevator body 1 stops suddenly, which will cause injury.
