Description

Technical Field

[0001] This invention belongs to the field of hospital logistics technology, specifically relating to a fire-resistant partition safety crossing device for a hospital logistics track system. Background Technology

[0002] With the increasing demand for hospital supplies transportation, traditional manual delivery methods can no longer meet the requirements of efficiency, safety, and cleanliness. Automated logistics track systems have therefore been widely adopted, significantly improving the efficiency and management of the transport of medicines, specimens, and medical instruments. However, when a track system needs to traverse multiple fire compartments, directly penetrating them would compromise the integrity of the firewalls, creating continuous "openings." This not only violates the mandatory requirements of the "Code for Fire Protection Design of Buildings" but also becomes a conduit for the spread of fire and smoke during a fire, seriously threatening personnel evacuation, firefighting, and the safety of medical facilities, posing a significant fire hazard.

[0003] Some design schemes attempt to use "track flip-down" technology to solve the problem of fire compartment crossing, that is, to connect and disconnect tracks between different fire compartments by setting up flip-down track sections. However, such schemes generally adopt a hinged structure with one side as the fixed rotation point and the other side as the free swing end. Limited by the space constraints of the track system, which is usually installed close to building walls or fire-resistant components, the track can only flip downwards to avoid the closed path of the firewall. This structural form has obvious defects in practical applications: due to frequent flipping movements over a long period, the supporting structure and connecting parts are prone to mechanical fatigue and deformation. In particular, the free swing end lacks effective support, and under the influence of gravity and repeated stress, it is prone to sinking or displacement. The cumulative deformation causes the swing end of the track to fail to accurately align with adjacent tracks when it returns to the working state, resulting in problems such as misalignment, step protrusions, or excessive gaps. This seriously affects the smooth passage of the cargo trolley and may even cause operational failures such as jamming or derailment, making it difficult to meet the technical requirements of hospital logistics systems for high reliability, high-precision docking, and long-term stable operation. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a safe passage device for fire-resistant zones in a hospital logistics track system, so as to solve the problems existing in the background art.

[0005] To address the aforementioned technical problems, the present invention provides a fire-resistant partition safety crossing device for a hospital logistics track system. This device facilitates the transition between different fire-resistant partitions of the track system. It includes a first track and a second track located in different fire-resistant partitions. A fire-resistant component and a docking component are provided between the first track and the second track. The docking component has a docking rail for connecting the first track and the second track. This docking rail is flipped, allowing it to switch between an operational state and a retracted state. In the operational state, the docking rail aligns with and connects to the first and second tracks, forming a continuous track system. In the retracted state, the docking rail flips to detach from the track system, disconnecting the first and second tracks. The flipping points of the docking rail are located on both sides of the fire-resistant component and avoid its active area, ensuring that when the docking rail switches to the retracted state, it does not obstruct the normal closing or opening of the fire-resistant component, thus guaranteeing the integrity of the fire-resistant partition function.

[0006] Preferably, to avoid the problem of difficulty in rotating the first and second tracks when they are installed close to building components, the rotation point is set to be height-adjustable: the rotation point is height-adjustable, and the direction of movement of the rotation point is parallel to but does not coincide with the plane where the fireproof component is located; by adjusting the height of the rotation point, when the first and second tracks are installed close to building components, the docking components can be adjusted by raising and lowering the rotation point to drive the docking rail to switch between working and stored states; thereby adapting to different installation space conditions and ensuring the reliability of the docking action and fire safety performance.

[0007] Furthermore, the docking component includes a mounting frame, which is elliptical and mounted on the building component, and the flipping point of the docking rail is rotatably mounted on the mounting frame; the docking rail is rotatably mounted on the mounting frame, thereby enabling the docking rail to have both elliptical and flipping functions.

[0008] Furthermore, a technical solution for realizing the lifting and flipping functions of the docking rail is as follows: The docking component includes a first linear moving component and a flipping motor; the first linear moving component is disposed on the mounting frame and the building component, and the lifting and lowering of the mounting frame on the building component is realized through the first linear moving component; the flipping motor is fixedly disposed on the mounting frame, and the output shaft of the flipping motor is connected to the docking rail; the lifting and flipping functions of the docking rail are realized through the first linear moving component and the flipping motor.

[0009] Furthermore, a second technical solution for realizing the lifting and flipping functions of the docking rail is as follows: The docking component includes a second linear moving component, a drive rack, and a drive gear. The second linear moving component is used to realize the lifting and lowering of the mounting frame on the building component. The drive rack is fixedly installed on the building component, and the drive gear is rotatably installed on the mounting frame. The drive rack and the drive gear selectively mesh. During the lifting and lowering process of the mounting frame controlled by the second linear moving component, when the preset flipping start position is reached, the drive gear and the drive rack enter a meshing state. As the mounting frame continues to move, the drive gear rotates while rolling along the drive rack, thereby driving the docking rail to flip around the flipping point.

[0010] Furthermore, in branch one of technical solution two: the drive gear is fixedly connected to the rotating shaft of the docking rail, and the rotation center of the drive gear coincides with the flipping point of the docking rail; when the mounting frame initially rises and falls, the drive gear is not engaged with the drive rack; when entering the flipping operation section, the drive gear and the drive rack engage, causing the drive gear to rotate while rising and falling with the mounting frame, and directly transmits this rotation to the docking rail to complete the flipping action.

[0011] Furthermore, in branch two of technical solution two: the docking component includes a transmission wheel, a driven wheel, and a transmission component. The transmission wheel and the drive gear are coaxially driven. The driven wheel is fixedly mounted on the docking rail, and the rotation center of the driven wheel coincides with the flipping point of the docking rail. The driven wheel is rotatably mounted on the mounting bracket. The transmission component connects the transmission wheel and the driven wheel, and is used to transmit power from the transmission wheel to the driven wheel. The rotation of the drive gear drives the transmission wheel to rotate, and the transmission component drives the driven wheel to rotate around its rotation center, thereby causing the docking rail to flip around the flipping point, realizing the switching between its working state and storage state.

[0012] Furthermore, the specific structure of branch two of technical solution two: the transmission component is a chain or synchronous belt, and the transmission wheel and the driven wheel are respectively a sprocket or a pulley; when the drive gear drives the transmission wheel to rotate, the transmission component transmits the motion to the driven wheel. Under the structural design that the rotation center of the driven wheel coincides with the reversing point of the docking rail, the precise reversing action of the docking rail is realized, ensuring the reliability of the rail connection or disconnection, while avoiding interference with the closure of the fireproof components.

[0013] Preferably, the two ends of the docking rail are made of a telescopic structure and / or elastic material. When the docking rail switches states, the two ends of the docking rail generate a buffering effect through the telescopic structure or elastic material to ensure the smooth switching of the docking rail states.

[0014] Furthermore, when the docking rail adopts a telescopic structure, the docking rail includes a fixed member and a movable member that are slidably disposed relative to each other, and an elastic reset element is provided between the fixed member and the movable member.

[0015] The main technical effects of this invention are reflected in the following aspects:

[0016] This invention employs a design concept that allows the connecting rail to switch between operating and retracted states, achieving coordinated control of rail connectivity and fireproof isolation. In the event of a fire, the connecting rail can quickly flip and detach from the track, creating a physical break and providing unobstructed space for the complete closure of fireproof roller shutters or fire doors. This ensures that fireproof components can function properly and block the spread of fire and smoke. This design fundamentally solves the safety hazard of traditional through-type rails compromising fireproof integrity, meets mandatory fire safety inspection requirements, and significantly improves the overall fire safety level of hospital buildings.

[0017] Addressing the issue that logistics tracks in hospital buildings are often located close to walls, beams, and columns, making traditional tilting tracks difficult to operate due to space constraints, this invention designs the tilting point of the docking track as a liftable structure. Its direction of movement is parallel to but does not coincide with the plane of the fire-resistant components. By adjusting the height of the tilting point, the orientation and path of the docking track can be flexibly adjusted in confined spaces, avoiding collisions or jamming with the building structure. This design significantly enhances the equipment's adaptability to complex installation environments, enabling the track system to operate stably under various building layouts, expanding its application scope, and improving the feasibility of engineering implementation.

[0018] Unlike traditional solutions that require separate lifting and tilting motors, this invention utilizes the automatic meshing of the drive gear and fixed rack during the lifting process of the mounting frame to convert linear motion into rotational motion, thereby driving the docking rail to complete the tilting action. This linkage mechanism eliminates the need for an additional tilting power unit, relying solely on a single linear moving component to complete all actions. This significantly reduces the number of parts, the complexity of control logic, and potential failure points, lowering manufacturing costs and maintenance difficulty. Simultaneously, the mechanical meshing transmission offers precise response and is less prone to slippage, avoiding the problem of motion loss due to motor synchronization errors or signal delays, thus significantly improving the system's operational stability and long-term reliability.

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, 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, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0025] The fire-resistant passage device for hospital logistics track systems provided by this invention is mainly used in safe transition scenarios between different fire-resistant zones within hospital automated logistics track systems. It is particularly suitable for cross-zone transport of high-cleanliness, high-time-sensitivity materials such as medicines, test specimens, and sterile instrument packs. However, it is not limited to this application. This device can also be extended to other places with high fire-resistant separation requirements and need to achieve automated track-based transport, such as cleanrooms, biological laboratories, pharmaceutical workshops, archives, data centers, and other building environments with similar fire-resistant zone isolation requirements. It is also suitable for fire-resistant passage nodes of automated material handling systems or track-based inspection equipment in these environments.

[0026] Furthermore, as common knowledge in this industry, the fire-resistant component 3 mentioned above specifically refers to building partition structures with a certain fire resistance limit, such as firewalls, fire-resistant roller shutters, and fire doors, used to prevent the spread of fire and smoke. The "building component 4" includes main building structures or auxiliary structural components such as walls, beams, columns, and floor slabs. The aforementioned structures and their functions, layout principles, and fire resistance requirements in building fire protection design are all technically common knowledge and widely adopted by professionals in this industry. Relevant standards can be implemented with reference to national or industry standards such as the "Code for Fire Protection Design of Buildings" (GB 50016). Meanwhile, the docking methods between tracks, such as the alignment of track end faces, height consistency control, horizontal transition accuracy, and how to ensure the smooth passage of transport trolleys through joints, are also common knowledge in this field. In automated logistics track systems, track docking must meet strict installation tolerances and achieve smooth connection by setting transition slopes, elastic buffer pads, floating connection structures, or guide flanges to avoid jumping, jamming, derailment, or excessive noise during vehicle operation. Such docking and support measures have been successfully applied in medical logistics systems, AGV guide rails, and automated warehousing conveyor lines, and are well-known to those skilled in the art. Therefore, this article will not elaborate on their basic principles, installation methods, and material composition.

[0027] Example 1

[0028] See Figure 1 , Figure 2 This embodiment discloses a fire compartment safety crossing device for a hospital logistics track system, used to realize the transition of the track system between different fire compartments. It includes a first track 1 and a second track 2 located on different fire compartments. A fireproof component 3 and a docking component 5 are provided between the first track 1 and the second track 2. The fireproof component 3 (such as a firewall or fireproof roller shutter) is used to block the spread of fire and smoke when a fire occurs, so as to achieve coordination between the functional connectivity and fire protection integrity of the track system.

[0029] The docking component 5 has a docking rail 51 for connecting the first track 1 and the second track 2. The docking rail 51 is flipped, allowing it to switch between an operating state and a retracted state. In the operating state, the docking rail 51 is aligned and connected with the first track 1 and the second track 2, forming a continuous track system. In the retracted state, the docking rail 51 flips to disengage from the track system, disconnecting the first track 1 and the second track 2. The docking rail 51 serves as a transition track segment, switching between the "operating state" and the "retracted state" through its flipping action. When the system is in normal operating mode, the docking rail 51 flips to a horizontal position, with its two ends aligned and connected with the first track 1 and the second track 2, forming a continuous and smooth track path for the logistics trolley to pass smoothly. When a fire alarm signal or maintenance command is received, the docking rail 51 flips to a vertical or tilted retracted state, disengaging from the original track line, thereby providing unobstructed space for the complete closure of the fireproof component 3 (such as a fireproof roller shutter), ensuring the effectiveness of the physical isolation of the fire compartment.

[0030] The key improvement lies in the fact that the flipping point of the docking rail 51 is located on both sides of the fireproof component 3 and avoids the active area of ​​the fireproof component 3 (such as the lifting channel of the fireproof roller shutter). This ensures that when the docking rail 51 is switched to the retracted state, it will not obstruct the normal closing or opening action of the fireproof component 3, thus guaranteeing the integrity of the fireproof separation function. Simultaneously, the flipping point itself has a lifting function; the flipping point is set in a lifting manner, and the direction of movement of the flipping point is parallel to and does not coincide with the plane where the fireproof component 3 is located (i.e., it is offset laterally or vertically along the wall). By adjusting the height of the flipping point, when the first rail 1 and the second rail 2 are installed close to the building component 4, the docking component 5 can drive the docking rail 51 to switch between the working state and the retracted state through the lifting adjustment of the flipping point; thereby adapting to different installation space conditions and ensuring the reliability of the docking action and fire safety performance.

[0031] Specifically, the mounting frame 52 is connected to the building component 4 (such as a wall embedded part or steel structure support) via a first linear moving component (such as an electric push rod, servo cylinder, or lead screw module) to achieve overall lifting and lowering movement. The docking rail 51 is rotatably mounted on the mounting frame 52 via a rotating shaft, the center of which is the flipping point. The flipping motor is fixedly mounted on the mounting frame 52, and its output shaft is directly or via a coupling connected to the rotating shaft of the docking rail 51 to drive the docking rail 51 to complete a precise flipping action. During operation, when it is necessary to disconnect the rail connection, the first linear moving component first drives the mounting frame 52 to descend to the predetermined flipping starting height, and then the flipping motor starts, driving the docking rail 51 to rotate downward around the flipping point to the storage position; during reset, the operation is reversed: the flipping motor first restores the docking rail 51 to a horizontal position, and then the first linear moving component raises the mounting frame 52 to the working height to ensure that the docking rail 51 is precisely aligned with the rails on both sides. This step-by-step control method effectively avoids motion interference and improves the stability of the action. That is: the docking component 5 includes a first linear moving component and a flipping motor; the first linear moving component is disposed on the mounting frame 52 and the building component 4, and the mounting frame 52 is raised and lowered on the building component 4 through the first linear moving component; the flipping motor is fixedly disposed on the mounting frame 52, and the output shaft of the flipping motor is connected to the docking rail 51; the lifting and flipping functions of the docking rail 51 are realized through the first linear moving component and the flipping motor.

[0032] To further enhance the smoothness and fault tolerance of the docking process, the two ends of the docking rail 51 adopt a telescopic structure and / or are made of elastic material. When the docking rail 51 switches states, the two ends of the docking rail 51 generate a buffering effect through the telescopic structure or elastic material, ensuring the smooth switching of the docking rail 51. When the docking rail 51 adopts a telescopic structure, the docking rail 51 includes a fixed part and a moving part that are relatively slidably arranged, and the two are in a sliding fit relationship with a coaxial sleeve, and can extend and retract relative to each other within a certain stroke range. An elastic reset element (such as a helical compression spring, disc spring or rubber elastomer) is provided between the fixed part and the moving part. When the docking rail 51 resets to the working state and contacts the first rail 1 and the second rail 2, the telescopic section is compressed to generate a small compression stroke, absorbing the impact force caused by installation errors or mechanical vibration, realizing flexible docking, and preventing rigid collisions from causing rail deformation or trolley jumping. In addition, the docking end face can also be covered with a layer of elastic material such as polyurethane or silicone to further enhance the shock absorption and noise reduction effect.

[0033] It is worth noting that if there is a height difference or sliding gap between the fixed and moving parts in the telescopic structure, steps or gaps may form when the trolley passes through, affecting the passage quality. To avoid such problems, this embodiment adopts a multi-segment small-pitch sliding nested structure: that is, multiple stepped nested moving segments are set along the axial direction inside the fixed part, with each segment slidingly engaged and the spacing between them being extremely small, forming an approximately continuous transition surface. This design not only ensures the realization of the telescopic function, but also greatly reduces the risk of misalignment between segments, making the entire docking area surface flat and without abrupt changes, ensuring that the logistics trolley can smoothly and imperceptibly cross the track joint, improving the overall operating quality of the system.

[0034] Example 2

[0035] Compared to the scheme in Embodiment 1, which uses an independent lifting mechanism and a flipping motor to control the movement of the mounting frame 52 and the attitude of the docking rail 51 respectively, this embodiment has a highly integrated and simplified structural design. It realizes that the lifting and flipping functions of the docking rail 51 can be completed by only one drive source - the second linear moving part 53, which significantly reduces the control difficulty and maintenance cost.

[0036] See Figure 3 , Figure 4 The equipment still includes a first track 1 and a second track 2 located within adjacent fire compartments, with fire-resistant components 3 (such as fire-resistant roller shutters or fire doors) between them for physical isolation in the event of a fire. To ensure the continuous operation of the logistics system and the coordination of fire safety, the equipment is equipped with docking components 5. The key innovation of this embodiment is:

[0037] The docking component 5 includes a mounting frame 52, a second linear moving component 53, a drive rack 54, and a drive gear 55. The second linear moving component 53 (such as an electric push rod, servo electric cylinder, or hydraulic cylinder) is used to realize the lifting and lowering of the mounting frame 52 on the building component 4 (such as a wall pre-embedded bracket). The drive rack 54 is fixedly installed on the building component 4, and the drive rack 54 is fixedly installed on the side wall of the building component 4 in the vertical direction. Its length covers the stroke section required for the docking rail 51 to flip. The drive gear 55 is rotatably installed on the mounting frame 52. The drive rack 54 and the drive gear 55 selectively mesh. That is, in the initial stage of the lifting and lowering of the mounting frame 52, the drive gear 55 is located outside the drive rack 54, and the two are not in contact. When the mounting frame 52 descends to the preset "flipping start position", the drive gear 55 just enters the meshing area of ​​the drive rack 54 and begins to mesh with it and roll along it.

[0038] During this process, as the second linear moving component 53 continues to drive the mounting frame 52 downwards, the drive gear 55 rotates while descending under the constraint of the drive rack 54. Since the drive gear 55 is fixedly connected to the rotating shaft of the docking rail 51, and its rotation center coincides perfectly with the flipping point of the docking rail 51, the rotational motion is directly transmitted to the docking rail 51, causing it to smoothly flip downwards around the flipping point until it completely separates from the connection path between the first track 1 and the second track 2, entering the storage state. Conversely, when the system resumes normal operation, the mounting frame 52 rises, the drive gear 55 rolls in the opposite direction along the drive rack 54 and drives the docking rail 51 to rotate in the opposite direction and reset to the horizontal working state, realizing track connection. It cleverly converts linear motion into rotational motion, without the need for an additional flipping motor. It can achieve the linkage action of "first disconnecting the track, then avoiding the fireproof component 3" with only a single linear drive source. The structure is simple, the response is reliable, and the energy consumption is low, making it particularly suitable for hospital application scenarios with high requirements for space compactness and system reliability.

[0039] Furthermore, to enhance transmission flexibility and layout adaptability, this embodiment also provides an indirect transmission scheme: the docking component 5 includes a transmission wheel 56, a driven wheel 57, and a transmission element 58. The transmission wheel 56 and the drive gear 55 are coaxially driven. The driven wheel 57 is fixedly mounted on the docking rail 51, and the rotation center of the driven wheel 57 coincides with the flipping point of the docking rail 51. The driven wheel 57 is rotatably mounted on the mounting bracket 52. The transmission element 58 is connected between the transmission wheel 56 and the driven wheel 57, and is used to transmit power from the transmission wheel 56 to the driven wheel 57. The rotation of the drive gear 55 drives the transmission wheel 56 to rotate, and the transmission element 58 drives the driven wheel 57 to rotate around its rotation center, thereby causing the docking rail 51 to flip around the flipping point, realizing the switching between its working state and storage state. Specifically, the transmission component 58 is a chain or synchronous belt, and the transmission wheel 56 and the driven wheel 57 are correspondingly sprockets or pulleys. When the drive gear 55 drives the transmission wheel 56 to rotate, the transmission component 58 transmits motion to the driven wheel 57. With the rotation center of the driven wheel 57 coinciding with the flipping point of the docking rail 51, the precise flipping action of the docking rail 51 is achieved, ensuring the reliability of track connection or disconnection, while avoiding interference with the closure of the fireproof component 3. The advantages of the indirect transmission structure are: it allows a certain spatial distance between the drive gear 55 and the rotating shaft of the docking rail 51, facilitating layout optimization in confined spaces; at the same time, the chain or synchronous belt drive has a certain fault tolerance, can adapt to slight installation deviations, and is convenient for maintenance and replacement. In addition, by reasonably designing the transmission ratio, the flipping speed of the docking rail 51 can be adjusted to ensure smooth and shock-free operation. Throughout the entire flipping process, the flipping point of the connecting rail 51 is always located in the non-active areas on both sides of the fireproof component 3 (such as a fireproof roller shutter), ensuring that its flipping action will not hinder the normal closing of the fireproof component 3 and guarantee the effective isolation of the fire compartment in the event of a fire.

[0040] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
