Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically a safety protection structure for elevator hall doors mounted on an aerospace rocket. Background Technology

[0002] When elevator hall doors used for aircraft rocket launchers are in use, they typically operate solely through the connection between the car door opening / closing drive mechanism and the door knife. However, human-induced external pressure can deform the hall door, leading to insufficient smooth sliding within the door groove and structural instability. Even slight displacement of the hall door when the car door knife disengages can cause incomplete closure, preventing the car from moving up or down, which relies on a closed hall door. Reopening the door can then result in elevator malfunction. Furthermore, the lack of sealing at the connection between the sill groove and the hall door slider allows dust and debris to fall into the sill groove, causing unstable sliding or even jamming of the hall door. Additionally, the hall door is not completely fixed when the elevator is fully closed or open. A sudden malfunction could injure passengers inside or outside the hall. Finally, the lack of prior notification to passengers before the elevator opens or closes can cause fright and injury if the doors suddenly close. Summary of the Invention

[0003] The purpose of this invention is to address the following issues: Elevator hall doors in aircraft rocket-mounted elevators typically open and close solely through the connection between the car door opening / closing drive device and the door knife. When the hall door is deformed due to external pressure or the car door knife disengages from the hall door, the resulting slight displacement can easily lead to insufficient smooth sliding of the hall door groove, structural instability, and ultimately, loose door closure. This can prevent the car from moving up or down, which relies on the hall door being closed, and subsequent door reopening can cause elevator malfunctions. Furthermore, the lack of sealing at the connection between the sill groove and the hall door slider allows dust and other debris to fall into the sill groove, causing unstable sliding or even jamming of the hall door. Additionally, the hall door is not completely fixed when passengers are getting on or off, and a sudden malfunction can easily injure passengers inside or outside the hall. Finally, the lack of prior notification to passengers before the elevator opens or closes can cause sudden door closure, leading to fright and injury. Therefore, this invention provides a safety protection structure for aircraft rocket-mounted elevator hall doors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a safety protection structure for an elevator hall door of an aviation rocket frame, including a wall surface, a hall door groove provided in the wall surface, a hall door slidably connected in the hall door groove, a pre-tightening device provided between the opposite surfaces of the hall door and the hall door groove, the pre-tightening device including a multi-layer pre-tightening structure formed by a first pull rod, a sliding rod, a second pull rod and a pre-tightening block, multiple sliding rods are arranged relatively vertically and slidably connected in arc-shaped sliding grooves at corresponding positions on the front and back of the hall door groove, one end of the first pull rod is hinged to the side of the inner wall of the hall door groove and the other end is movably sleeved on the sliding rod, one end of the second pull rod is fixed to the sliding rod and the other end is hinged to the side of the hall door, the pre-tightening block is suspended on the sliding rod by a belt, a sill is provided below the hall door groove, the sill includes a sill groove parallel to the hall door, an electromagnet is provided at the bottom of the sill groove, a slider is provided at the bottom of the hall door, the slider is slidably connected in the sill groove and a magnet corresponding to the electromagnet is provided at its bottom, and a sensing module is also provided on the hall door.

[0005] As a further description of the above technical solution:

[0006] The concave surface of the arc-shaped sliding groove faces the hinge of the first tie rod and the hall door groove, and its lowest point is higher than the corresponding hinge of the first tie rod and the hall door groove, and the second tie rod and the hall door.

[0007] As a further description of the above technical solution:

[0008] A limiting ring is installed on the slide bar, and the upper end of the belt is sleeved on the slide bar and abuts against the outside of the limiting ring.

[0009] As a further description of the above technical solution:

[0010] The belt on the relatively high slide rod is looped onto the other slide rods below, and its bottom is fixed to both ends of the preload block.

[0011] As a further description of the above technical solution:

[0012] The sill groove is a T-shaped sill groove, and the slider is a T-shaped slider with rollers on both sides of its upper end that are rolled and connected to the upper end of the sill groove, while its lower end is suspended in the sill groove. The upper end of the sill groove is provided with sealing strips on both sides. The sealing strips are soft sealing strips, such as belt sealing strips.

[0013] As a further description of the above technical solution:

[0014] A groove is made at the bottom of the slider, and a positioning sleeve is connected to the groove for lifting. A magnet is fixed inside the positioning sleeve, and the bottom of the positioning sleeve is lower than the bottom of the magnet to form a positioning groove.

[0015] As a further description of the above technical solution:

[0016] The electromagnet is equipped with a positioning block corresponding to the positioning slot. The electromagnet is electrically connected to an external power supply, and the magnetism exhibited at its upper end is the same as that at the lower end of the magnet.

[0017] As a further description of the above technical solution:

[0018] The hall door surface is equipped with a broadcast module and a display module.

[0019] As a further description of the above technical solution:

[0020] The sensing module, broadcasting module, display module and controller are electrically connected.

[0021] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0022] 1. This elevator hall door safety protection structure can be used in elevators with rocket mounts. Through a multi-layered tightening structure consisting of a first tie rod, a second tie rod, a sliding rod, and an arc-shaped sliding groove, combined with a belt connection method where higher layers interlock with lower layers, and a pre-tensioning block counterweight, an inward pre-tensioning structure is formed on the hall door. This ensures a tighter closure of the hall door, avoiding the problem of the hall door being deformed due to external pressure caused by the connection between the car door opening and closing drive device and the door knife. This also prevents insufficient smooth sliding with the hall door groove, structural instability, and minor damage to the hall door when the car door knife disengages from the hall door. Displacement can cause the hall door to not close tightly, preventing the elevator car from moving up or down, which relies on the hall door being closed. Reopening the door can lead to elevator malfunction. To address this, a T-shaped slider and T-shaped sill groove work together to ensure smooth sliding and reduce the resistance to opening and closing the hall door. A locking structure using a positioning sleeve and positioning block, combined with the repulsive force between the electromagnet and magnet when energized and the falling magnet when de-energized, ensures that the hall door is completely fixed when the elevator is fully closed and open, preventing sudden hall door malfunctions that could injure passengers inside or outside the hall.

[0023] 2. A sealing strip is installed at the connection between the sill groove and the hall door slider to ensure smooth sliding of the slider and reduce the amount of dust and other debris falling into the sill groove, which could cause the hall door to slide unstably or even jam. A broadcast and display module connected to the controller and the sensing module is installed to convey information to passengers that the elevator is about to open or close, so as to avoid the elevator door suddenly closing and causing fright and injury to passengers, thereby improving the elevator's user experience and safety.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Example 1:

[0034] Please see Figure 1-4 This invention provides a technical solution: a safety protection structure for an elevator hall door of an aviation rocket frame, including a wall 1, a hall door groove 11 set in the wall 1, a hall door 2 slidably connected in the hall door groove 11, a pre-tightening device set between the opposite surfaces of the hall door 2 and the hall door groove 11, the pre-tightening device including a multi-layer pre-tightening structure formed by a first pull rod 13, a sliding rod 14, a second pull rod 15 and a pre-tightening block 17, multiple sliding rods 14 are relatively vertically arranged and slidably connected in arc-shaped sliding grooves 12 at corresponding positions on the front and rear sides of the hall door groove 11, one end of the first pull rod 13 is hinged to the side of the inner wall of the hall door groove 11 and the other end is movably sleeved on the sliding rod 14, one end of the second pull rod 15 is fixed to the sliding rod 14 and the other end is hinged to the side of the hall door 2, the pre-tightening block 17 is suspended on the sliding rod 14 by a belt 16, and a sill 3 is set below the hall door groove 11, the sill 3 including a sill parallel to the hall door 2. The bottom of the sill groove 31 is equipped with an electromagnet 32, and the bottom of the hall door 2 is equipped with a slider 21. The slider 21 is slidably connected in the sill groove 31 and has a magnet 23 corresponding to the electromagnet 32 ​​at its bottom. The hall door 2 is also equipped with a sensing module 24. This elevator hall door safety protection structure can be used in elevators for aviation rocket racks. Through a multi-layer tightening and pre-tightening structure, the hall door closes more tightly, avoiding the way that the hall door is opened and closed by only relying on the connection between the car door opening and closing drive device and the door knife. Due to the deformation of the hall door caused by external pressure, the sliding between the hall door groove and the door is not smooth enough, the structure is unstable, and the slight displacement of the hall door when the car door knife is separated from the hall door causes the hall door to close loosely. This makes it impossible for the car to move up and down on the premise that the hall door is closed. When the door is opened again, it causes the elevator to malfunction. By using the slider and the sill groove to slide smoothly, the resistance to the opening and closing of the hall door is reduced.

[0035] The concave surface of the arc-shaped slide groove 12 faces the hinge of the first pull rod 13 and the hall door groove 11, and its lowest point is higher than the hinge of the corresponding first pull rod 13 and hall door groove 11, and the second pull rod 15 and hall door 2, so as to avoid the pull rods from becoming taut and stuck in the tightening structure.

[0036] A limiting ring 141 is provided on the slide rod 14. The upper end of the belt 16 is sleeved on the slide rod 14 and abuts against the outside of the limiting ring 141 to prevent the belt from slipping and causing the pre-tightening block to collide with the hall door groove and the hall door.

[0037] Example 2:

[0038] Please see Figure 3 Based on the above embodiment 1, preferably, the belt 16 on the relatively high slide rod 14 is sleeved on the other slide rods 14 in the lower layer and its bottom is fixed to both ends of the pre-tightening block 17. The belt connection method of the high layer sleeved on the low layer, combined with the counterweight of the pre-tightening block, forms a pre-tightening structure inward toward the hall door, so that the hall door closes more tightly and the pre-tightening block is in a vertical state, reducing its shaking.

[0039] Example 3:

[0040] Please see Figure 1 , 2 4. Based on the above embodiment 1, preferably, the sill groove 31 is a T-shaped sill groove, the slider 21 is a T-shaped slider with rollers on both sides of its upper end rollingly connected to the upper end of the sill groove 31, and its lower end is suspended in the sill groove 31. The upper end of the sill groove 31 is provided with sealing strips 33 on both sides. The sealing strips 33 are soft sealing strips, such as belt sealing strips. The sealing strips are provided at the connection between the sill groove and the hall door slider to ensure smooth sliding of the slider while reducing the amount of dust and other debris falling into the sill groove.

[0041] Example 4:

[0042] Please see Figure 1 , 2 4. Based on the above embodiment 1, preferably, a groove is opened at the bottom of the slider 21, and a positioning sleeve 22 is connected to the groove for lifting. A magnet 23 is fixed inside the positioning sleeve 22. The bottom of the positioning sleeve 22 is lower than the bottom of the magnet 23 to form a positioning groove. A positioning block corresponding to the positioning groove is provided on the electromagnet 32. The electromagnet 32 ​​is electrically connected to an external power supply, and the magnetism at its upper end is the same as the magnetism at its lower end. The locking structure of the hall door by the positioning sleeve and the positioning block, combined with the repulsive force between the electromagnet and the magnet when energized and the closing method of the magnet falling when de-energized, ensures that the hall door is completely fixed when the elevator is fully closed and open, avoiding sudden failure of the hall door and causing injury to passengers inside and outside the hall door.

[0043] Example 5:

[0044] Please see Figure 1 Based on the above embodiment 1, preferably, the surface of the hall door 2 is provided with a broadcast module 25 and a display module 26. The sensing module 24, the broadcast module 25, the display module 26 are electrically connected to the controller. The broadcast and display modules are connected to the sensing module through the controller to convey the information that the elevator is about to open or close to the passengers, so as to avoid the sudden closing of the elevator door and cause fright and injury to the passengers, thereby improving the user experience and safety of the elevator.

[0045] The working principle of the safety protection structure for an elevator hall door of an aviation rocket frame in this embodiment includes: When the elevator is level, the induction device inside the elevator is linked with the control switch of the electromagnet 32, so that the electromagnet 32 ​​is energized and exhibits the same magnetism as the magnet 23, thereby driving the positioning sleeve 22 to rise and disengage from the positioning block on the electromagnet 32. The door knife on the car door is connected to the corresponding position of the hall door 2 (land door). The built-in drive device of the car door drives the car door to open. Through the connection structure between the door knife and the hall door 2, the hall door 2 is opened. The second pull rod 15 pushes the slide rod 14 outward, so that it slides obliquely upward along the arc-shaped slide groove 12, thereby driving the second pull rod 15 to rotate at an increased angle. At the same time, the first pull rod 13 follows the slide rod 14 to rotate upward at an increased angle, thereby driving the belt 16 and the pretension block 17 to lift. The pretension structure is lifted and tightened as a whole, which is the second use state (e.g. Figure 4 When hall door 2 reaches the elevator door frame, it stops, electromagnet 32 ​​is de-energized, and positioning sleeve 22 falls and fits onto positioning block for positioning, ensuring that hall door 2 will not close abnormally during passenger access and avoid injury. After passengers have finished accessing the elevator, sensing module 24 senses objects outside hall door 2. If no target is sensed within a certain period of time, the controller controls broadcast module 25 and display module 26 to broadcast "elevator door closed" information to passengers, avoiding sudden closure of the elevator door and causing fright and injury. Electromagnet 32 ​​is energized and rises to unlock, and car door knife drives hall door to close. At the same time, through the mass and inertia of pre-tightening block 17, hall door 2 is pressed and closed a second time, so that both sides of hall door 2 are tightly closed. Electromagnet 32 ​​is de-energized, positioning sleeve 22 and positioning block are locked together. At this time, elevator car door knife disengages from hall door 2, and elevator car can move up and down to other floors.

[0046] In summary, due to the adoption of the above technical solution, the safety protection structure for an elevator hall door of an aviation rocket frame in this embodiment has the following advantages compared with the prior art:

[0047] 1. This elevator hall door safety protection structure can be used in elevators with rocket mounts. Through a multi-layered tightening structure consisting of a first tie rod, a second tie rod, a sliding rod, and an arc-shaped sliding groove, combined with a belt connection method where higher layers interlock with lower layers, and a pre-tensioning block counterweight, an inward pre-tensioning structure is formed on the hall door. This ensures a tighter closure of the hall door, avoiding the problem of the hall door being deformed due to external pressure caused by the connection between the car door opening and closing drive device and the door knife. This also prevents insufficient smooth sliding with the hall door groove, structural instability, and minor damage to the hall door when the car door knife disengages from the hall door. Displacement can cause the hall door to not close tightly, preventing the elevator car from moving up or down, which relies on the hall door being closed. Reopening the door can lead to elevator malfunction. To address this, a T-shaped slider and T-shaped sill groove work together to ensure smooth sliding and reduce the resistance to opening and closing the hall door. A locking structure using a positioning sleeve and positioning block, combined with the repulsive force between the electromagnet and magnet when energized and the falling magnet when de-energized, ensures that the hall door is completely fixed when the elevator is fully closed and open, preventing sudden hall door malfunctions that could injure passengers inside or outside the hall.

[0048] 2. A sealing strip is installed at the connection between the sill groove and the hall door slider to ensure smooth sliding of the slider and reduce the amount of dust and other debris falling into the sill groove, which could cause the hall door to slide unstably or even jam. A broadcast and display module connected to the controller and the sensing module is installed to convey information to passengers that the elevator is about to open or close, so as to avoid the elevator door suddenly closing and causing fright and injury to passengers, thereby improving the elevator's user experience and safety.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
