Description

Technical Field

[0001] This invention relates to the field of logistics door opening technology, specifically a heavy-duty logistics sliding door opening machine that can be manually released in the event of a power outage. Background Technology

[0002] Logistics parks, smart warehouses, and automated factories are typical application scenarios for intelligent logistics equipment. Currently, heavy-duty sliding door openers adapted to intelligent logistics systems mainly fall into two categories for handling power outages: one is an electrical emergency solution that adds an industrial-grade UPS backup power supply and energy storage batteries, and the other is a mechanical emergency solution equipped with a simple manual clutch. However, neither of these solutions can meet the requirements of intelligent logistics equipment for all-weather, high reliability, and minimal human intervention. The specific shortcomings are as follows: The backup power electrical emergency solution has significant shortcomings in adapting to smart logistics scenarios, resulting in high overall operation and maintenance costs and limited battery life and emergency scenarios. Smart logistics door openers that are not equipped with backup power or whose energy storage power has failed generally use a worm gear self-locking reduction structure. After a power outage or electrical control failure, the motor output end and the bottom tooth plate of the door remain locked in a hard engagement. Without a quick disengagement and engagement mechanism, the door cannot be manually pushed. A few simple clutch mechanisms are only single fork or single-point locking structures, with short unlocking strokes and cumbersome operation. Some high-position clutches even require climbing to operate, making them inconvenient to use.

[0003] Regarding the manual labor-saving emergency mechanism for heavy-duty sliding doors, existing technologies still have two long-standing industry pain points that have not been effectively addressed: First, existing manual door opening mechanisms with pulley systems generally use elastic elements to directly pull the I-shaped movable pulley to achieve reset, resulting in resistance from the tension of the elastic elements during manual opening and closing; Second, to achieve bidirectional manual drive for opening and closing the door, the industry practice is to configure two independent manual labor-saving mechanisms, one for opening and one for closing. Two mechanisms result in more components and occupy more installation space, which is not conducive to the integrated design of the warehouse with access control and sensor modules, and increases both manufacturing costs and wiring difficulty. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a heavy-duty logistics sliding door opener that can be manually disengaged in the event of a power outage. It features rapid mechanical disengagement in the event of a power outage, bidirectional labor-saving manual opening and closing, automatic gravity-driven reset of the pulleys, lightweight emergency operation by a single person, and the ability to adapt to various power outage conditions in warehouses without relying on a backup power source. This solves the technical problems of existing intelligent logistics sliding door openers, such as high maintenance costs due to reliance on backup power and the inability to manually push or pull due to self-locking during power outages. Furthermore, this invention does not present a technical approach in this field that involves tilting the slide rail by flipping the entire labor-saving mechanism and relying on the counterweight to drive the I-shaped movable pulley back to its original position, thereby eliminating the direct reset spring of the I-shaped movable pulley. (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A heavy-duty logistics sliding door opener that can be manually disengaged in the event of a power outage includes a support frame that slides with the heavy-duty logistics sliding door and an intelligent logistics door opener for driving the heavy-duty logistics sliding door to move; a transmission part is snapped onto the output end of the intelligent logistics door opener; the transmission part meshes with the heavy-duty logistics sliding door; a sliding part that rotates with the transmission part is slidably provided on the side of the intelligent logistics door opener; a support plate is fixed to the surface of the support frame; a U-shaped seat is rotatably provided on the side of the support plate; and a force-saving part is rotatably provided on the U-shaped seat.

[0008] Preferably, a rotating shaft that rotatably engages with the support plate is fixed to the side of the U-shaped seat; an arc-shaped tube coaxial with the rotating shaft is fixed to the side of the support plate; an arc-shaped rod that slidably engages with the arc-shaped tube is fixed to the side of the U-shaped seat; a return spring is connected between the arc-shaped rod and the arc-shaped tube; and a stop bar is fixed to the outer wall of the arc-shaped rod.

[0009] Preferably, a limit rod is fixed between the inner walls of the U-shaped seat; a shaft hole is opened on the surface of the rotating plate to rotatably engage with the limit rod; a circular plate coaxial with the shaft hole is fixed on the surface of the rotating plate; through holes are symmetrically opened on the surface of the circular plate; an annular cavity communicating with the two through holes is opened inside the circular plate; straight guide grooves and oblique guide grooves communicating with each other are opened on the side of the rotating plate; the straight guide grooves and oblique guide grooves are adapted to the I-shaped movable pulley; a through hole communicating with the oblique guide groove, and a ball head is slidably arranged inside it; a push rod is fixed on the ball head; a fixing ring is fixed on the outer wall of the push rod; an annular plate that slidably engages with the annular cavity is fixed on the outer wall of the fixing ring; a locking rod that is slidably arranged through the side of the U-shaped seat and inserted into the corresponding through hole is slidably arranged; a stop block is fixed on the top of the locking rod; a support spring sleeved on the locking rod is connected between the stop block and the U-shaped seat.

[0011] Preferably, a rotating column is rotatably provided on the side of the support plate; a coaxial annular handle and a gear ring one are fixed sequentially on the circumferential side of the rotating column; a gear ring two that meshes with the gear ring one is fixed on the circumferential side of the I-beam roller; the outer diameter of the gear ring one is larger than the outer diameter of the gear ring two.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a heavy-duty logistics sliding door opener that can be manually disengaged in the event of a power outage, which has the following advantages: 1. This invention, by setting up an axially movable sliding part, guides the overall displacement of the transmission part through a screw and slide rod, simultaneously disconnecting the output end locking structure of the intelligent logistics door opener from the gear meshing of the door body tooth plate, completely severing the mechanical transmission link between the intelligent logistics door opener and the heavy-duty door body, overcoming the self-locking and seizing defects of worm gear mechanisms when power is off. After power failure or electrical control malfunction, there is no need for backup power supplies such as UPS or batteries, saving on the continuous operation and maintenance investment of purchasing, regularly replacing, and inspecting energy storage equipment. It is suitable for emergency conditions in warehouses and factories with no or unstable power supply.

[0013] 2. The present invention features a pitch-rotation pair between the labor-saving part and the support plate. After emergency operation, simply flip the entire labor-saving part to tilt the slide rail. The counterweight rod built into the moving pulley will automatically slide back to the initial position along the slide rail under its own weight, eliminating the need for manual rope pullback. This completely eliminates the elastic component that directly pulls the moving pulley in the traditional solution, avoiding the reverse pulling resistance of the elastic component when manually opening and closing the intelligent logistics door opener. The matching arc tube, arc rod and return spring form a return assembly. After the external force is released, the labor-saving mechanism can automatically return to the horizontal working posture, simplifying the operation process for maintenance personnel.

[0014] 3. The labor-saving part of this invention relies on a U-shaped base to form a horizontal slewing joint, allowing the entire unit to rotate horizontally and switch the direction of the connecting rope tension. Only one set of moving and fixed pulley assemblies is needed to simultaneously complete bidirectional manual drive for opening and closing the door, abandoning the traditional industry standard of two independent labor-saving mechanisms. This significantly reduces the number of parts in the entire machine, compresses the horizontal installation space, and facilitates integrated layout with warehouse access control, security sensors, and automatic alarm modules. Simultaneously, it reduces the manufacturing costs and construction difficulty of the entire machine's processing, assembly, and on-site wiring.

[0015] 4. This invention sets up a ball head, top rod, and locking rod linkage limiting assembly between the U-shaped seat and the rotating plate. Under normal conditions, the locking rod automatically inserts and locks the rotating plate, ensuring the stable working posture of the pulley group and preventing deviation or rope jamming during the opening and closing process. When switching the opening and closing direction of the door, the movable pulley slides and squeezes the ball head to automatically push open the locking rod and release the limit. After flipping and resetting, the limiting structure automatically locks, eliminating the need for additional manual insertion and removal of the locking pin, thus simplifying the operation steps.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Example 1: This embodiment provides a heavy-duty logistics sliding door opener that can be manually disengaged in the event of a power outage, and has the following technical features.

[0038] Please see Figure 1-16The system includes a support frame 2 that slides with a heavy-duty sliding door 1 and an intelligent logistics door opener 3 for driving the heavy-duty sliding door 1 to move. A transmission part 4 is snapped onto the output end of the intelligent logistics door opener 3. The transmission part 4 meshes with the heavy-duty sliding door 1. A sliding part 5 is slidably provided on the side of the intelligent logistics door opener 3 and rotates with the transmission part 4. The sliding part 5 supports the transmission part 4 and drives it to move axially, realizing rapid engagement and disengagement with the output end of the heavy-duty sliding door 1. A support plate 6 is fixed on the surface of the support frame 2. A U-shaped seat 7 is rotatably provided on the side of the support plate 6. A force-saving part 8 is rotatably provided on the U-shaped seat 7. The force-saving part 8 can rotate horizontally around the U-shaped seat 7 to switch the direction of the pulling force. The Labor-Saving Department 8 includes: Rotating plate 9, rotating plate 9 and U-shaped seat 7 are rotatably engaged; An I-shaped movable pulley 10 is slidably fitted with a rotating plate 9; a counterweight rod 11 is fixedly fixed inside the I-shaped movable pulley 10; half-stop rings 12 that are adapted to the counterweight rod 11 are symmetrically fixed on the side of the heavy-duty logistics sliding door 1. Fixed pulley 13 is rotatably mounted on the side of rotating plate 9; Baffle 14 is fixed on the side of the rotating plate 9 and serves as the fixing point for the connecting rope 15. And a connecting rope 15, one end of which is connected to the side of the baffle 14, and the other end passes through the I-shaped movable pulley 10 and the fixed pulley 13 in sequence; the connecting rope 15 is made of high-strength nylon composite rope, one end of which is tied to the baffle 14, and the other end first goes down around the lower side of the I-shaped movable pulley 10, then goes up around the outside of the fixed pulley 13 and extends outward to form a force-saving pulley group structure.

[0039] Rotating the force-saving part 8 around the support plate 6 causes the rotating plate 9 to rotate and tilt. Under the action of gravity, the counterweight rod 11 slides back to its original position along the rotating plate 9. Rotating the force-saving part 8 around the U-shaped seat 7 changes the direction of the tension of the connecting rope 15, thereby realizing the force-saving opening / closing of the heavy-duty logistics sliding door 1.

[0040] The U-shaped seat 7 and the support plate 6 form a pitch-rotor joint, allowing the entire force-saving part 8 to pitch and rotate relative to the support plate 6, thus tilting the slide of the force-saving part 8. The U-shaped seat 7 and the force-saving part 8 form a horizontal rotary joint, allowing the force-saving part 8 to rotate horizontally relative to the U-shaped seat 7 to switch the direction of rope tension. The pitch-rotor joint and the horizontal rotary joint are coupled together to realize the two functions of automatic gravity reset of the I-shaped movable pulley 10 and bidirectional drive of the heavy-duty logistics sliding door 1 by a single mechanism, solving the pain points of existing technology where direct reset of elastic elements causes tension resistance during the opening and closing process and requires two sets of manual mechanisms for bidirectional opening and closing.

[0041] Working principle: When the intelligent logistics door opener 3 is powered on, it works normally. The output end fixed plate 25 and slot 26 clamp the clamping rod 24 on the I-beam roller 23, driving the transmission part 4 to rotate synchronously. When the intelligent logistics door opener 3 is started, the output end drives the transmission part 4, which is engaged with it, to rotate synchronously, thereby driving the heavy-duty logistics sliding door 1, which is engaged with the transmission part 4, to move horizontally along the support frame 2, realizing the opening / closing of the heavy-duty logistics sliding door 1.

[0042] In the event of a power outage or malfunction, the sliding part 5 moves, thereby driving the transmission part 4 to move away from the intelligent logistics door opener 3. This disengages the transmission part 4 from the output end of the intelligent logistics door opener 3, releasing the locking limit between the transmission part 4 and the intelligent logistics door opener 3. Simultaneously, it releases the engagement limit between the transmission part 4 and the heavy-duty logistics sliding door 1, cutting off the mechanical hard connection between the intelligent logistics door opener 3 and the heavy-duty logistics sliding door 1. This allows the heavy-duty logistics sliding door 1 to move freely horizontally along the support frame 2, facilitating subsequent opening / closing operations of the heavy-duty logistics sliding door 1.

[0043] Pull one end of the connecting rope 15, and the connecting rope 15 will pull the I-shaped movable pulley 10 to move horizontally along the rotating plate 9. After the counterweight rod 11 on the I-shaped movable pulley 10 moves to contact the corresponding half-stop ring 12, as the I-shaped movable pulley 10 continues to move, it will drive the half-stop ring 12 to move synchronously with the heavy-duty logistics sliding door 1, so as to realize the opening / closing of the heavy-duty logistics sliding door 1. This realizes the manual and labor-saving opening / closing of the heavy-duty logistics sliding door 1, replacing the traditional method of opening / closing the door through a backup power supply.

[0044] Because the labor-saving part 8 adopts a pulley block structure, the tension direction of one end of its connecting rope 15 is unique, which cannot meet the needs of the heavy-duty logistics sliding door 1 for opening / closing in both directions. At the same time, in this working environment, the labor-saving part 8 is applied in a horizontal position. After each operation in a single direction is completed, the I-shaped movable pulley 10 cannot be quickly reset. It is necessary to add a reset structure or manually push the I-shaped movable pulley 10 along the rotating plate 9 to reset it. If a reset structure is added, the cost will increase. If it is manually pushed, the operation is cumbersome and inconvenient to use.

[0045] Therefore, the effort-saving part 8 of the present invention, together with the U-shaped seat 7, can rotate vertically around the support plate 6, causing the rotating plate 9 to rotate and tilt. Under the action of gravity, the counterweight rod 11 slides back to its original position along the rotating plate 9. The operation is simple and facilitates the normal operation of subsequent operations. At the same time, the effort-saving part 8 can rotate horizontally around the U-shaped seat 7, thereby changing the direction of the tension of the connecting rope 15, realizing the effort-saving opening and closing operation of the heavy logistics sliding door 1.

[0046] In summary, through the structural design of the sliding part 5, the transmission part 4, and the intelligent logistics door opener 3, the transmission between the intelligent logistics door opener 3 and the heavy-duty logistics sliding door 1 can be quickly cut off when the power is cut off, eliminating the risk of mechanical seizure and making it suitable for heavy sliding doors in logistics plants. The rotating plate 9 can rotate horizontally to switch the direction of tension of the connecting rope 15. One set of labor-saving mechanism can simultaneously meet the two working conditions of opening and closing the door, eliminating the need for two additional sets of manual devices, thus reducing the equipment's footprint and cost.

[0047] In summary, this invention forms a collaborative working architecture by setting up two levels of mutually coupled rotary joints, rather than simply stacking individual components: the pitch rotary joint enables the overall pitch and rotation of the effort-saving part 8, causing the slide rail of the rotating plate 9 to tilt. The counterweight rod 11 then drives the I-shaped movable pulley 10 to slide and reset along the slide rail, eliminating the need for the elastic element in the existing technology that directly pulls the I-shaped movable pulley 10, thus avoiding the reverse pulling force of the elastic element and increasing resistance; the horizontal rotary joint enables the horizontal rotation of the effort-saving part 8 to switch the direction of the tension of the connecting rope 15; the horizontal rotary joint and the pitch rotary joint are integrated into the same effort-saving part 8, working together to simultaneously achieve the two functions of gravity-based reset of the I-shaped movable pulley 10 without elastic elements and bidirectional manual opening and closing of the heavy-duty logistics sliding door 1 using only a single effort-saving mechanism. This differs from the conventional solution in the industry that requires two independent effort-saving mechanisms for bidirectional manual operation, significantly reducing the number of components in the entire machine, compressing the equipment installation space, facilitating integrated layout with warehouse sensing and access control modules, and reducing the manufacturing cost and on-site wiring difficulty of the entire intelligent logistics door equipment. The overall effect of this coupling combination is not a simple summation of the inherent effects of individual rotating structures, counterweights, and pulleys.

[0056] Working Principle: This invention addresses the labor-saving operation of opening / closing a heavy-duty logistics sliding door 1 under two different scenarios, including power outages or malfunctions. Initially, the I-shaped movable pulley 10 is away from the fixed pulley 13. Regardless of the scenario, first, the screw 17 is rotated, causing the slide plate 19 to slide along the two slide rods 16 away from the fixed plate 25. This disengages each set of locking rods 24 from their corresponding slots 26, releasing the locking and limiting relationship between the fixed plate 25 and the transmission part 4. At this time, the gear 28 at the end of the extension rod 27 slides away from the toothed plate 29 fixed at the bottom of the heavy-duty logistics sliding door 1, releasing... In addition to limiting the transmission of the heavy-duty logistics sliding door 1, at the same time, each set of plug rods 40 moves and inserts into the corresponding plug holes 42 on the side of the take-up wheel 41. The first gear ring 46 and the second gear ring 47 are in a meshing state. At this time, the heavy-duty logistics sliding door 1 can move horizontally along the support frame 2. The connecting cloth 43 at the end of the connecting rope 15 is wrapped and glued to the inner wall of the take-up wheel 41. Since the outer diameter of the first gear ring 46 is larger than the outer diameter of the second gear ring 47, and the two are meshed, rotating the ring handle 45 drives the first gear ring 46 to rotate, which in turn drives the second gear ring 47 to rotate, further improving the labor-saving effect.

[0057] With the rotating plate 9 and the heavy-duty logistics sliding door 1 in a parallel state, the I-shaped movable pulley 10 is placed in the straight guide groove 51. The ball head 53 is not subjected to compressive force. Under the action of gravity, the ball head 53 extends out of the corresponding through hole 49 and enters the inclined guide groove 52. The annular plate 56 is placed on the bottom surface of the annular cavity 50 under the action of gravity. The two push rods 54 are stored in the corresponding through holes 49. The support spring 59 is in the normal state. The locking rod 57 is inserted into the corresponding through hole 49 to limit the rotation plate 9, so that the rotating plate 9 remains parallel to the heavy-duty logistics sliding door 1, ensuring the stability of the working posture of the pulley group, and preventing deviation or rope jamming during the opening and closing process, which facilitates the normal opening / closing operation of the labor-saving part 8.

[0058] Scenario 1: During a power outage or malfunction, the heavy-duty logistics sliding door 1 is in the open position, such as... Figure 4 As shown, at this point, it is necessary to close the heavy-duty logistics sliding door 1. Pulling the connecting rope 15 cannot close the heavy-duty logistics sliding door 1. The specific operation is as follows: Rotating the rotating plate 9 clockwise causes the U-shaped seat 7 to rotate synchronously, stretching the return spring. A push rod 54, adapted to another set of through holes 49, is fixed to the surface of the annular plate 56. Under gravity, the I-shaped movable pulley 10 slides from the straight guide groove 51 into the inclined guide groove 52. Under the pressure of gravity from the I-shaped movable pulley 10, the ball head 53 slides into the corresponding through hole 49. The corresponding push rod 54 pushes the locking rod 57 out of the corresponding through hole 49, compressing the support spring 59. The rotating plate 9 is retracted, releasing the restriction on the rotating plate 9. It then rotates 180° around the limiting rod 37, ensuring it remains parallel to the heavy-duty logistics sliding door 1. The rotating plate 9 is lowered, and under the reset action of the return spring, it rotates synchronously with the U-shaped seat 7 to its reset position. The I-shaped movable pulley 10 slides along the inclined guide groove 52 onto the straight guide groove 51, releasing the pressure on the ball head 53. Under the elastic reset action of the support spring 59, it drives the locking rod 57 to insert into the corresponding through hole 49. Figure 5 As shown, this enables automatic locking and unlocking of the rotating plate 9.

[0059] Rotating the ring handle 45 causes the gear ring 46 to rotate, which in turn causes the gear ring 47 and the winding wheel 41 to rotate synchronously, so that the connecting rope 15 is wound up by the winding wheel 41. The connecting rope 15 pulls the I-shaped movable pulley 10 towards the fixed pulley 13. When the counterweight rod 11 on the I-shaped movable pulley 10 moves and contacts the corresponding half-stop ring 12, the heavy-duty logistics sliding door 1 moves synchronously through the half-stop ring 12 as the I-shaped movable pulley 10 continues to move, thus closing the heavy-duty logistics sliding door 1.

[0060] After the heavy-duty logistics sliding door 1 is closed, the I-shaped movable pulley 10 moves closer to the fixed pulley 13, as... Figure 5 As shown, rotating the rotating plate 9 counterclockwise causes the U-shaped seat 7 to rotate around the support plate 6. The arc-shaped rod 35 rotates and retracts into the arc-shaped tube 34 until the stop rod 36 abuts against the end of the arc-shaped tube 34. The return spring is compressed, and the rotating plate 9 is tilted. Under the gravity of the counterweight rod 11, the I-shaped movable pulley 10 slides along the rotating plate 9 away from the fixed pulley 13 to return to its original position. During this process, the I-shaped movable pulley 10 pulls the connecting rope 15 to move synchronously, and the connecting rope wound on the winding wheel 41... The rope 15 is released under tension, completing the rapid reset of the I-shaped movable pulley 10. Then, the connecting cloth 43 is removed from the winding wheel 41. The above operation causes the U-shaped seat 7 and the rotating plate 9 to rotate synchronously, releasing the limit on the rotating plate 9. The rotating plate 9 is rotated around the limit rod 37 to complete the reset of the rotating plate 9. This process does not rely on the spring directly acting on the I-shaped movable pulley 10. It uses the pitch and rotation joint to tilt the slide, and the counterweight completes the reset and releases the limit on the rotating plate 9 and the U-shaped seat 7.

[0061] Scenario 2: When there is a power outage or malfunction, the heavy-duty logistics sliding door 1 is in the closed state. At this time, it is necessary to open the heavy-duty logistics sliding door 1. As above, turn the ring handle 45 to drive the winding wheel 41 to wind up the connecting rope 15, which drives the I-shaped movable pulley 10 to move synchronously with the heavy-duty logistics sliding door 1, so that the heavy-duty logistics sliding door 1 is stored in the support frame 2, thus completing the opening of the heavy-duty logistics sliding door 1. The subsequent reset operation is the same as in Scenario 1, and will not be described in detail here.

[0062] In summary, this heavy-duty logistics sliding door opener, which can be manually disengaged after power failure, achieves primary labor saving through its internal I-shaped movable pulley 10 and fixed pulley 13, while the external large and small gear rings mesh to form a gear reduction and force amplification, achieving secondary labor saving. For ultra-heavy-duty sliding doors in logistics plants, a single person can easily push and pull them without the need for multiple people to cooperate. During the reset process, the I-shaped movable pulley 10 releases the limit between the rotating plate 9 and the U-shaped seat 7 through the pressure of gravity.
