Description

Technical Field

[0001] This application relates to the field of elevator rescue, and in particular to a rescue docking device, method and system for the safety door of an inclined elevator car. Background Technology

[0002] Inclined elevators, as a special type of elevator adapted to non-vertical transportation scenarios, are widely used in scenic corridors, inclined passageways across floors, and large industrial plants. Their core feature is that the car runs along a track with a preset inclination angle (usually 15°–75°) to transport people and goods between different elevations. Compared to traditional vertical elevators, inclined elevators have significantly different operating trajectories, car postures, and door layouts, which enhances their safety.

[0003] Chinese patent disclosure CN217024905U, entitled "A Rescue Device for Inclined Elevator Cars," describes a rescue device installed between the elevator car and the safety passage. This device transfers passengers from the elevator car to the safety passage. However, this method requires the construction of a safety passage, and the transfer from the inclined elevator to the safety passage involves the passengers crawling, posing safety concerns. Patent CN217296832U proposes a "Rescue Device for Two Inclined Elevators," where the rescue device is installed between the first and second cars, connecting them. Both of these inclined elevator rescue devices require rescue personnel to prepare, transport, and install them. In general, current rescue devices for inclined elevators that stop outside a landing due to a malfunction and cannot be restarted rely on manual transport and installation, which is cumbersome and may even slow down the rescue process. Summary of the Invention

[0004] This application provides a rescue docking device, method and system for the safety door of a sloping elevator car, which solves the technical problem that the rescue methods for passengers in a malfunctioning sloping elevator are cumbersome and still have safety issues in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, a rescue docking device for the safety door of a inclined elevator car is provided, including a car and a fixed bracket fixed on the car. A foldable guardrail bridge mechanism is installed on the car. The guardrail bridge mechanism is limited by a diagonal steel wire rope set on the fixed bracket. The guardrail bridge mechanism is provided with a positioning electromagnetic lock and a docking electromagnetic lock.

[0007] Based on the above technical solution, in the inclined elevator car safety door rescue docking device provided in this application, when a car malfunctions, the opposite inclined elevator is controlled to carry out rescue and align with the malfunctioning inclined elevator, so that the guardrail bridge mechanism on the two cars can dock to form a safety passage. At this time, the passengers can walk from the malfunctioning inclined elevator to the rescue inclined elevator.

[0008] In conjunction with the first aspect above, in one possible implementation, the fixed support includes two upper support brackets, an upper bracket, a middle bracket, and a lower bracket arranged in a counter-bracing manner;

[0009] The guardrail bridge crossing mechanism includes a bridge bottom plate, a horizontal guardrail, a guardrail top plate, and vertical railings connected thereto. The two lower supports are connected to the two sides of the bridge bottom plate via a pivot shaft on opposite sides, and one end of the upper support is connected to one end of the guardrail top plate via a pivot shaft.

[0010] In conjunction with the first aspect above, in one possible implementation, a drive module is installed on the fixed bracket. The drive module includes a synchronous motor mounted on the middle bracket and a main rotating shaft located on the output shaft of the synchronous motor. One end of the main rotating shaft is connected to the horizontal guardrail, and the output end of the drive module drives the guardrail bridge mechanism to fold or retract through the main rotating shaft.

[0011] In conjunction with the first aspect above, in one possible implementation, the car includes a car top, car walls, car floor, and an openable safety door.

[0012] In conjunction with the first aspect mentioned above, in one possible implementation, the fixed bracket is equipped with a guardrail retraction switch and a guardrail unfolding switch.

[0013] In conjunction with the first aspect mentioned above, in one possible implementation, the car is also equipped with lighting indicator lights.

[0014] Secondly, a method for rescuing and docking the safety door of a inclined elevator car is provided, including:

[0015] Control the rescue inclined ladder equipped with the docking device to move to the side of the malfunctioning inclined ladder;

[0016] The rescue inclined ladder sends a signal to the malfunctioning inclined ladder to deploy the bridge railing. After receiving the signal, the malfunctioning inclined ladder releases the electromagnetic lock.

[0017] The guardrail bridge mechanisms on the rescue inclined ladder and the faulty inclined ladder open simultaneously until the docking electromagnetic lock on the rescue inclined ladder engages with the docking electromagnetic lock on the faulty inclined ladder.

[0018] In conjunction with the second aspect above, in one possible implementation, the rescue inclined ladder sends a signal to the faulty inclined ladder to retract the bridge railing, and upon receiving the signal, the faulty inclined ladder disengages from the electromagnetic lock.

[0019] The guardrail bridging mechanisms on the rescue and malfunctioning inclined ladders are retracted until they return to a state where the set electromagnetic lock can close, and then the set electromagnetic lock is controlled to close.

[0020] Thirdly, this application provides a processing apparatus, comprising: a processor and a storage medium; the storage medium includes instructions, and the processor is configured to execute the instructions to implement the methods described in the first aspect and any possible implementation thereof. The processing apparatus may be an electronic device or a chip within an electronic device.

[0021] Fourthly, this application provides a rescue docking system for a inclined elevator car safety door, comprising: a control module and a command switch module; wherein, the control module is used to receive a bridge railing deployment signal and a bridge railing retraction signal; and to control the locking or unlocking of the docking electromagnetic lock and the setting electromagnetic lock; the command switch module is used to generate a bridge railing deployment signal and a bridge railing retraction signal and send them to the control module.

[0022] Fifthly, this application provides a computer-readable storage medium storing instructions that, when executed on a processing device, cause the processing device to perform the methods described in the second aspect and any possible implementation thereof.

[0023] In a sixth aspect, this application provides a computer program product containing instructions that, when executed on a processing device, cause the processing device to perform the methods described in the second aspect and any possible implementation thereof.

[0024] This application provides a rescue docking device, method, and system for a inclined elevator car safety door. When an inclined elevator malfunctions, it aligns with the malfunctioning inclined elevator to facilitate rescue. After the two guardrail bridge mechanisms are aligned, the bridge base provides sufficient support, allowing passengers to walk as if on flat ground, avoiding the risk of missteps compared to climbing a ladder. Furthermore, the horizontal guardrail, top guardrail, and vertical railings provide barriers after docking, further enhancing safety and mitigating the psychological safety concerns of passengers with a fear of heights. After docking, the device further secures the safety by closing the positioning electromagnetic lock. The guardrail bridge mechanism folds down during docking, saving considerable time and simplifying operation. The main rotating shaft of the synchronous motor in the drive module rotates, driving the bridge mechanism to swing. Combined with the unfolding and positioning switch, automated unfolding is achieved, further improving docking efficiency, safety, and accuracy.

[0035] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0036] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0037] The inclined elevator car safety door rescue docking method provided in this application embodiment can be applied to, for example... Figure 1 In the inclined elevator car safety door rescue docking system 100 shown, such as Figure 1As shown, the communication system includes an elevator control module and a command switch module; wherein, the control module is used to receive the bridge railing deployment signal and the bridge railing retraction signal; control the locking of the docking electromagnetic lock 8 and the setting electromagnetic lock 7; and the rotation of the synchronous motor 91; the command switch module is used to generate the bridge railing deployment signal and the bridge railing retraction signal and send them to the control module.

[0038] To address the cumbersome and unsafe rescue methods for passengers in malfunctioning inclined elevators in existing technologies, this application provides a rescue docking device for the safety door of an inclined elevator car. The device includes a car 2 and a fixed support 1 fixed to the car 2. A retractable guardrail bridge mechanism 3 is installed on the car 2. The guardrail bridge mechanism 3 is limited by a diagonal steel wire rope 4 installed on the fixed support 1. The guardrail bridge mechanism 3 is equipped with a positioning electromagnetic lock 7 and a docking electromagnetic lock 8. Based on this, rapid and safe rescue of passengers can be achieved.

[0039] like Figure 2 As shown in the embodiment of this application, in a rescue docking device for a inclined elevator car safety door, the fixed bracket 1 includes two symmetrically arranged upper brackets 11, upper bracket 12, middle bracket 13 and lower bracket 14; furthermore, the two lower brackets 14 are also provided with bridging support blocks, which are installed on the lower brackets 14 and are triangular support structures, used for lower support and lower limit of the bridging after the bridging guardrail is fully deployed.

[0040] The bridge crossing mechanism 3 includes a bridge bottom plate 31, a horizontal guardrail 32, a guardrail top plate 34, and vertical guardrails 33 connected thereto. The bridge bottom plate 31, horizontal guardrails 32, and guardrail top plate 34 are all horizontal guardrails. These horizontal guardrails can rotate around a fixed support axis in the vertical plane and can drive the vertical guardrails to move up and down together in the vertical plane. The two lower supports 14 are connected to opposite sides of the bridge bottom plate 31 via pivot shafts. The bridge bottom plate 31 serves as the bottom crossing passage and its edge protection plate. The guardrail top plate 34 is used for top protection after the bridge crossing guardrail system is deployed.

[0041] One end of the upper support 12 is connected to one end of the guardrail top plate 34 via a pivot. The guardrail top plate 34 is connected to the top support 11 via a diagonal steel wire rope 4. The horizontal guardrail 32 is connected to the middle support 13 via a pivot. By installing the fixed support 1 and the guardrail bridge mechanism 3 in the above connection manner, not only can the folding of the guardrail bridge mechanism 3 be realized, but the installation is also relatively convenient. The pivot connection can be connected by a short shaft.

[0042] In the retracted state of guardrail bridge structure 3, as follows: Figure 2 and Figure 3 As shown, the guardrail bridge structure 3 unfolds as follows: Figure 4 and Figure 5 As shown.

[0043] The fixed bracket 1 is equipped with a drive module 9 for docking with the guardrail bridge mechanism 3. The drive module 9 includes a synchronous motor 91 mounted on the middle bracket 13 and a main rotating shaft 92 located on the output shaft of the synchronous motor 91. One end of the main rotating shaft 92 is connected to the horizontal guardrail 32. The output end of the drive module 9 drives the guardrail bridge mechanism 3 to fold or retract through the main rotating shaft 92. Specifically, the synchronous motor 91 is mounted on the middle bracket 13. When the synchronous motor 91 rotates, it drives the main rotating shaft 92 to rotate. The main rotating shaft 92 drives the horizontal guardrail 32 to rotate, thereby driving the vertical guardrail 33 and the other horizontal guardrails to rotate synchronously, thus completing the unfolding of the guardrail bridge mechanism 3.

[0044] The car 2 includes a car top 21, car walls 22, car floor 24 and an openable safety door 23; the car walls 22 include a left car wall panel 221 and a right car wall panel 222; when the safety door 23 is opened, passengers can pass through the opened area to enter the car 2 on the other side.

[0045] To ensure stability during docking, the fixed bracket 1 is equipped with a guardrail retraction switch 5 and a guardrail extension switch 6. The guardrail retraction switch 5 is located on the upper bracket 11, while the guardrail extension switch 6 is located on the lower bracket 14. The positioning electromagnetic lock 7 is located on the horizontal guardrail 32, and the docking electromagnetic lock 8 is located on the vertical guardrail 33.

[0046] The car 2 is also equipped with a lighting indicator 10; specifically, the lighting indicator 10 includes a guardrail top plate lighting 101 installed on the car top 21 and a bridge bottom plate lighting 102 installed on the bridge bottom plate 31. The lighting indicator 10 can be turned on as needed.

[0047] like Figure 2 As shown in the figure, an embodiment of this application provides a rescue docking method for the safety door of a inclined elevator car, including:

[0048] S201. The rescue inclined ladder with docking device is moved to one side of the faulty inclined ladder by controlling the control module.

[0049] After performing this step, the safety door 23 on the rescue inclined elevator needs to be opened using a triangular key. Once the two cars 2 are aligned, the bridge railing release button in the control box of the inclined elevator is used to generate a bridge railing deployment signal.

[0050] It should be noted that the elevator control module communicates with the elevator control module of the adjacent elevator via serial CAN or RS485, and is used to receive and send signals from the guardrail retraction switch 5 and the guardrail unfolding switch 6.

[0051] S202. The rescue inclined ladder sends a signal to the faulty inclined ladder to deploy the bridge railing. After receiving the signal, the set electromagnetic locks 7 on both the faulty and rescue inclined ladders retract their bolts and release the set lock.

[0052] S203, the guardrail crossing mechanism 3 on the rescue inclined ladder and the faulty inclined ladder opens synchronously until the docking electromagnetic lock 8 on the rescue inclined ladder cooperates with the docking electromagnetic lock 8 on the faulty inclined ladder.

[0053] like Figure 6 As shown, in some implementations, the guardrail bridge mechanism 3 on the rescue inclined ladder and the faulty inclined ladder opens simultaneously, including the following steps:

[0054] The synchronous motor 91 rotates, driving the horizontal guardrail 32 to rotate to the opposite side, further driving the vertical guardrail 33 and other horizontal guardrails to rotate synchronously until the bridge bottom plate 31 presses against the unfolding position switch 6. At this time, the unfolding position switch generates an unfolding position signal, and the elevator control module immediately stops the rotation of the synchronous motor 91. During this process, the inclined steel wire rope 4 also changes from a slack state to a taut state. After receiving the unfolding position signal, the fault inclined elevator and the rescue inclined elevator extend the pin lock head of the docking electromagnetic lock 8 and insert it into each other's slots to complete the docking and locking cooperation.

[0055] S204. After the passenger passes through the bridge railing mechanism 3 from the faulty inclined elevator, the elevator control module controls the rescue inclined elevator to send a bridge railing retraction signal to the faulty inclined elevator. After receiving the bridge railing retraction signal, the rescue inclined elevator and the faulty inclined elevator generate a docking start signal, and the power supply of the docking electromagnetic lock 8 stops outputting power, and the pin lock head of the docking electromagnetic lock 8 is disengaged.

[0056] S205 At this time, the guardrail bridge mechanism 3 on the rescue inclined ladder and the faulty inclined ladder is retracted until the guardrail bridge mechanism 3 on the rescue inclined ladder and the faulty inclined ladder returns to the state where the setting electromagnetic lock 7 can be closed, and then a setting start signal is generated to control the setting electromagnetic lock 7 to close.

[0057] In some implementations, the steps of folding and opening the guardrail bridge crossing mechanism 3 are reversed, which will not be elaborated further here.

[0058] The foregoing mainly describes the solutions of the embodiments of this application from the perspective of device implementation.
