Description

Technical Field

[0001] The utility model relates to the technical field of warehousing equipment. More specifically, the utility model relates to a lifting device and an intelligent warehousing equipment. Background Technique

[0002] Modern warehousing systems increasingly tend to develop towards high altitudes. The lifting structure allows the shelves and goods to move efficiently in the vertical direction, greatly improving the space utilization rate of the warehouse. In the prior art, the synchronous belt is usually directly embedded inside the profile (vertical track) in the lifting structure to form an integrated structure, but the manufacturing cost is relatively high and it is not conducive to inspection and maintenance.

[0003] In addition, some lifting structures in the prior art do not have a belt break detection mechanism: when the synchronous belt breaks, the unilateral lifting mechanism loses traction, and the other side continues to operate, which is likely to cause the load platform to tilt instantly and trigger safety accidents such as the slipping of goods. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a lifting device and an intelligent warehousing equipment to solve at least part of the technical problems mentioned in the above background technique, and has the advantages of simple structure, low manufacturing cost, and convenient inspection and maintenance.

[0005] To achieve the above object, the first aspect of the utility model provides the following technical solution: a lifting device for driving a load platform to move vertically. The lifting device includes a driving mechanism and two groups of parallel lifting mechanisms; the lifting mechanism includes: A track member, the track member is arranged vertically, and is made of a channel profile (the cross-section is in the shape of "匚", C or similar to C), and the openings of the track members of the two groups of lifting mechanisms face each other, and are used to constrain the running track of the synchronous belt; An installation platform, at least part of the installation platform is located above the track member and is fixedly connected to the track member; Two synchronous wheels, one of the two synchronous wheels is installed at the bottom of the track member, and the other of the two synchronous wheels is installed on the installation platform; A synchronous belt, the synchronous belt is in transmission cooperation with the two synchronous wheels, and one end of the synchronous belt is wound around one of the synchronous wheels, and the other end passes through the inside of the track member and is wound around the other synchronous wheel; A first slider for connecting with the load platform; the first slider is slidably installed on the track member and is fixedly connected to the synchronous belt; The drive mechanism is used to drive one of the two synchronous wheels to rotate, thereby moving the platform vertically; the mounting platform is provided with a mounting space for accommodating the synchronous wheel; the mounting space is in communication with the interior of the track component and has a top opening and a side opening.

[0006] The specific technical effects of this implementation are as follows: the track component is vertically continuous, the mounting platform is fixed at the top and provides space with "top opening + side opening", exposing the upper half of the belt. The belt "wraps around the bottom synchronous pulley at one end → passes through the inside of the track → wraps around the top synchronous pulley", forming a "half-hidden, half-visible" layout. When the inspection personnel stand in the tunnel, their line of sight can directly scan the entire length of the belt along the side opening, and any surface cracks or toothed corners can be detected immediately; during maintenance, there is no need to remove the track end cover, and the belt can be lifted for inspection simply by reaching in from the top or side opening, simplifying the maintenance path to "visible and tangible". The first slider is fixed to the belt, and the slider is guided by the track, so the belt-slider-platform form a rigid motion chain; the drive mechanism only needs to drive the synchronous pulley on either side to synchronize the torque to the opposite side through the linkage shaft, ensuring consistent lifting of the two tracks and eliminating the risk of twisting.

[0007] Optionally, the mounting platform includes a front mounting plate, a rear mounting plate, and two side mounting plates; the front mounting plate, side mounting plates, rear mounting plate, and side mounting plates are connected in sequence and enclose the mounting space; wherein, the side mounting plates are L-shaped.

[0008] The specific technical advantages of this implementation are as follows: Four panels—front, back, left, and right—form a U-shaped installation space, with the left and right side panels being L-shaped. The short side of the L-shape rests on the top of the track, while the long side extends downwards. This creates a "semi-open drawer": by loosening a few screws, the L-shaped side panels, along with the tensioning assembly, can be pulled out as a whole; the synchronous pulley, bearings, and detection plates are all exposed in the open space, allowing for component-level maintenance without disassembling the track. The short side of the L-shape also serves as the frame for the top opening; even after the belt passes through, it remains constrained by the short side, preventing instability due to the open structure.

[0009] Optionally, the lifting mechanism further includes a tensioning component disposed on the mounting platform; the tensioning component is drivenly connected to a synchronous pulley on the mounting platform to provide an upward force to the synchronous pulley and adjust the tension of the synchronous belt; The synchronous pulley is mounted on the mounting platform in a manner that allows it to move vertically.

[0010] The specific technical effects of this embodiment are as follows: the top synchronous pulley is no longer rigidly fixed, but "floats" inside the mounting platform; the tensioning component continuously applies an upward elastic force to the synchronous pulley. When the belt stretches, the elastic force automatically pushes the synchronous pulley upward, keeping the belt taut; when the temperature decreases and the belt contracts, the synchronous pulley is pulled downward in the opposite direction, preventing over-tensioning. Throughout the entire process, the tensioning stroke occurs inside the mounting platform, occupying no external space and not affecting the trajectory of the platform.

[0011] Optionally, the tensioning assembly includes a connector and a vertically arranged elastic element; the connector is mounted on the mounting platform in a manner that allows vertical movement; the synchronous pulley is rotatably mounted on the connector; and the elastic element is compressed between the connector and the mounting platform.

[0012] The specific technical advantages of this embodiment are as follows: the connector can slide up and down along the mounting platform, and the synchronous pulley is mounted on the connector; the elastic element is clamped between the connector and the mounting platform and is continuously compressed. The compression amount of the elastic element and the position of the synchronous pulley form a self-feedback relationship: the looser the belt, the longer the elastic element, the higher the synchronous pulley moves, and the tension is restored; and vice versa. The operator only needs to set the preload of the elastic element once, and the subsequent tension is dynamically balanced by the elastic element, eliminating the need for repeated manual intervention and eliminating human error.

[0013] Optionally, the connector includes a connecting body and a pressure plate protruding from the side of the connecting body; the connecting body is used for sliding connection with the mounting platform, and the synchronous wheel is rotatably mounted on the connecting body; the elastic element is compressed between the pressure plate and the mounting platform.

[0014] The specific technical effects of this embodiment are as follows: A pressure plate extends from the side of the connecting body, forming a "lever" structure. The elastic element acts on the pressure plate, which then transmits the evenly distributed force to the connecting body, ultimately supporting the entire synchronous pulley. The pressure plate increases the contact surface of the elastic element, reducing local stress; at the same time, the pressure plate is integrated with the connecting body, avoiding misalignment that may occur during separate welding, ensuring that the synchronous pulley shaft always maintains vertical translation and does not tilt.

[0015] Optionally, the tensioning assembly further includes a vertically arranged connecting shaft; the two ends of the connecting shaft are respectively installed between the pressure plate and the mounting platform; the elastic element includes a compression spring, which is sleeved and installed on the connecting shaft.

[0016] The specific technical effects of this embodiment are as follows: the connecting shaft vertically passes through the pressure plate and the mounting platform, and the compression spring is sleeved outside the connecting shaft. The connecting shaft acts as both an "inner guide rod" for the spring and restricts the spring to extend and retract only axially; even if the system vibrates, the spring will not jump out laterally, ensuring that the tensioning action is always in the vertical direction and avoiding lateral force interference with the synchronous pulley.

[0017] Optionally, the tensioning assembly further includes a slide rail and a second slider; the slide rail is fixedly mounted on the mounting platform; the second slider is slidably connected to the slide rail and fixedly connected to the connecting body.

[0018] The specific technical effects of this embodiment are as follows: a fixed slide rail is mounted on the mounting platform, and the connecting body cooperates with the slide rail through a second slider. The slide rail-slider pair forced synchronous wheel shaft can only perform pure linear lifting and lowering, eliminating rotational degrees of freedom; the center line of the belt always coincides with the center line of the track, avoiding belt rubbing against the track during tensioning.

[0019] Optionally, the lifting mechanism further includes a rotating shaft and a bearing; the rotating shaft is coaxially arranged and fixedly connected to the synchronous wheel on the mounting platform; the connecting body is provided with a horizontally arranged through hole for the rotating shaft to pass through; the bearing is sleeved on the rotating shaft and installed in the through hole.

[0020] The specific technical effects of this embodiment are as follows: the rotating shaft and the synchronous pulley are coaxially fixed, and a transverse through hole is opened on the connecting body, into which the bearing is installed. The inner ring of the bearing rotates with the rotating shaft, while the outer ring is fixed to the connecting body; thus, the tensioning assembly does not support a "cantilever shaft," but rather a simply supported beam structure with "support at both ends," significantly reducing the shaft deflection, making the synchronous pulley run more smoothly, and ensuring more uniform meshing between the belt teeth and the pulley teeth.

[0021] Optionally, the lifting mechanism further includes a rotating shaft and a detection component for detecting whether the timing belt is broken; the rotating shaft is coaxially arranged and fixedly connected to the timing pulley on the mounting platform; the detection component includes a detector mounted on the mounting platform and a detection plate mounted on one end of the rotating shaft; the detector is used to detect the rotation speed of the detection plate; wherein, when the rotation speed of the detection plate detected by the detectors in the two sets of lifting mechanisms is different, the detection component determines that the timing belt is broken.

[0022] The specific technical effects of this implementation are as follows: a detection plate is fixed to the outer end of the shaft of the top synchronous pulley; the detector reads the rotation speed of the detection plate. During normal operation, the speeds of the detection plates in the two sets of lifting mechanisms are consistent; if the belt on one side breaks, the corresponding synchronous pulley stops rotating, and the speed of the detection plate drops suddenly. The system immediately identifies the belt breakage through the "speed difference," which can trigger an emergency stop or brake, controlling the risk of tilting at an early stage. Since the detection plate is installed at the top opening, inspectors can also visually observe whether it has stopped rotating, achieving dual confirmation of "manual + automatic."

[0023] Optionally, the detection plate includes a detection body and a plurality of detection heads protruding outward from the detection body; the plurality of detection heads are evenly distributed circumferentially around the periphery of the detection body.

[0024] The specific technical effects of this embodiment are as follows: multiple protruding detection heads are evenly distributed on the outer edge of the detection plate, forming a "toothed disc" appearance. The detector only needs to identify the pulses passing through the detection heads. Even if some detection heads are blocked by dust, the remaining detection heads can still generate a sufficient pulse sequence. The even distribution around the circumference ensures multiple samplings within one rotation, improving the system's ability to identify low-speed or intermittent motion and further reducing the probability of missed detections.

[0025] The second aspect of this utility model provides the following technical solution: an intelligent warehousing equipment, including a lifting device as described above. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 and 2 The lifting device 2 shown is used to drive the vertical movement of the platform 3. The lifting device 2 includes a drive mechanism and two sets of parallel lifting mechanisms 21. The two sets of lifting mechanisms 21 are connected by a crossbeam 22. The crossbeam 22 should be positioned to avoid the operating space of the platform 3, for example, it can be positioned at the same height as the shelf platform.

[0030] In a multi-tier shelf scenario, two sets of vertical tracks must be kept strictly parallel; otherwise, the belts on one side will be unevenly stressed, and the load platform 3 will tend to "twist". Conventionally, the belts are entirely enclosed inside the profiles, making it impossible to see either the belt wear or whether the belts have jumped off the tracks. Therefore, the lifting mechanism 21 in the embodiments of the present disclosure includes a track member 23, a mounting platform 24, two synchronous pulleys 210, a synchronous belt 211, and a first slider. The track member 23 is vertically arranged. The mounting platform 24 is at least partially located above the track member 23 and is fixedly connected to the track member 23. One of the two synchronous pulleys 210 is mounted at the bottom of the track member 23, and the other of the two synchronous pulleys 210 is mounted on the mounting platform 24. The synchronous belt 211 is in transmission cooperation with the two synchronous pulleys 210, and one end of the synchronous belt 211 is wound around one of the synchronous pulleys 210, and the other end passes through the interior of the track member 23 and is then wound around the other synchronous pulley 210; the first slider is used to connect to the load platform 3; the first slider is slidably mounted on the track member 23 and is fixedly connected to the synchronous belt 211.

[0031] Among them, the driving mechanism is used to drive one of the two synchronous pulleys 210 to rotate so as to drive the load platform 3 to move vertically; the mounting platform 24 is provided with a mounting space for accommodating the synchronous pulley 210; the mounting space is communicated with the interior of the track member 23 and has a top opening and a side opening.

[0032] The track member 23 is vertically through, and the mounting platform 24 is fixed at the top and provides a space of "top opening + side opening", making the upper half of the belt exposed. The belt is arranged in a way that "one end is wound around the synchronous pulley 210 at the bottom → passes through the interior of the track → is wound around the synchronous pulley 210 at the top", forming an arrangement of "half hidden and half visible". When the inspection personnel stand in the roadway, the line of sight can directly sweep across the entire length of the belt along the side opening, and any surface cracks or tooth-shaped bevels can be immediately detected; during maintenance, there is no need to remove the track end cover, and only by reaching in through the top or side opening, the belt can be lifted for inspection. The maintenance path is simplified to "visible and touchable". The first slider is fixed to the belt, and the slider is guided by the track. Thus, the belt-slider-load platform 3 forms a rigid motion chain; the driving mechanism only needs to drive any one of the synchronous pulleys 210 on one side, and the torque can be synchronized to the other side through the linkage shaft, ensuring the consistent lifting of the double tracks and eliminating the hidden danger of twisting.

[0033] Specifically, the vertical track is in a "U" shape or a C shape or a C-like shape, and the openings of the track are arranged opposite to each other, and a part of the synchronous belt 211 is located inside the track profile.

[0034] If the mounting platform 24 is a closed box, the internal synchronous pulley 210, bearings, and tensioning assembly 25 are all buried deep inside, requiring the entire platform to be disassembled when replacing the bearings. Therefore, as an optional implementation, the mounting platform 24 includes a front mounting plate 241, a rear mounting plate 242, and two side mounting plates 243 on the left and right. The front mounting plate 241, side mounting plates 243, rear mounting plate 242, and side mounting plates 243 are connected sequentially and enclose to form an installation space; among them, the side mounting plates 243 are L-shaped. The four plates, front, rear, left, and right, form a "U"-shaped installation space, with the left and right side plates being L-shaped, the short side of the L-shape resting on the top of the track, and the long side extending downwards. This forms a "semi-open drawer": by loosening a few screws, the L-shaped side plates along with the tensioning assembly 25 can be pulled out as a whole; the synchronous pulley 210, bearings, and detection plates are all exposed in the open space, allowing for component-level maintenance without disassembling the track. The short side of the L-shape also serves as the frame of the top opening. After the belt is passed through, it is still constrained by the short side and will not become unstable due to the open structure.

[0035] Seasonal temperature differences or long-term creep can cause the belt to elongate. If the top synchronous pulley 210 is fixed, the belt will sag, resulting in a reduced wrap angle with the drive pulley, causing "tooth crawling" noise or even tooth skipping. Therefore, as an optional implementation, the lifting mechanism 21 also includes a tensioning component 25 mounted on the mounting platform 24. The tensioning component 25 is drivenly connected to the synchronous pulley 210 on the mounting platform 24 to provide an upward force to the synchronous pulley 210. The synchronous pulley 210 is mounted on the mounting platform 24 in a vertically movable manner. The top synchronous pulley 210 is no longer rigidly fixed, but "floats" inside the mounting platform 24. The tensioning component 25 continuously applies an upward elastic force to the synchronous pulley 210. When the belt elongates, the elastic force automatically pushes the synchronous pulley 210 upward, keeping the belt taut. When the temperature drops and the belt contracts, the synchronous pulley 210 is pulled downward in the opposite direction to avoid over-tensioning. The tensioning stroke occurs inside the mounting platform 24 throughout the process, without occupying external space or affecting the running trajectory of the platform 3.

[0036] If bolt-tightening is used, the operator needs to rely on experience to tighten the bolts, which may lead to a sudden increase in bearing load due to overtightening at once. Therefore, as an optional implementation, the tensioning assembly 25 includes a connector 251 and a vertically arranged elastic element 252. The connector 251 is mounted on the mounting platform 24 in a vertically movable manner. The timing pulley 210 is rotatably mounted on the connector 251. The elastic element 252 is compressed between the connector 251 and the mounting platform 24. The connector 251 can slide up and down along the mounting platform 24, and the timing pulley 210 is mounted on the connector 251. The elastic element 252 is clamped between the connector 251 and the mounting platform 24 and is continuously compressed. The compression of the elastic element 252 and the position of the timing pulley 210 form a self-feedback relationship: the looser the belt, the longer the elastic element 252 extends, the timing pulley 210 moves upward, and the tension is restored; and vice versa. The operator only needs to set the preload of the elastic element 252 once, and the subsequent tension is dynamically balanced by the elastic element 252, eliminating the need for repeated manual intervention and eliminating human error.

[0037] If the elastic element 252 directly presses against the shaft end of the synchronous pulley 210, the small area of ​​the shaft end will concentrate the pressure, easily causing a dent to be pressed into the shaft end. Therefore, if Figure 3 As shown, in one optional embodiment, the connector 251 includes a connecting body 2511 and a pressure plate 2512 protruding from the side of the connecting body 2511. The connecting body 2511 is slidably connected to the mounting platform 24, and the synchronous wheel 210 is rotatably mounted on the connecting body 2511. An elastic element 252 is compressed between the pressure plate 2512 and the mounting platform 24. A pressure plate 2512 protrudes from the side of the connecting body 2511, forming a "lever" structure. The elastic element 252 acts on the pressure plate 2512, and the pressure plate 2512 then transmits the uniform force to the connecting body 2511, ultimately supporting the entire synchronous wheel 210. The pressure plate 2512 increases the contact surface of the elastic element 252, reducing local stress; at the same time, the pressure plate 2512 is integrated with the connecting body 2511, avoiding misalignment that may occur during separate welding, ensuring that the axis of the synchronous wheel 210 always maintains vertical translation and does not tilt.

[0038] If a compression spring is allowed to extend and contract freely, it is prone to "bulging" and dislodging from its mounting position during lateral swaying. Therefore, as an optional implementation, the tensioning assembly 25 also includes a vertically arranged connecting shaft 253; the two ends of the connecting shaft 253 are respectively installed between the pressure plate 2512 and the mounting platform 24; the elastic element 252 includes a compression spring, which is sleeved and installed on the connecting shaft 253. The connecting shaft 253 vertically penetrates the pressure plate 2512 and the mounting platform 24, and the compression spring is sleeved outside the connecting shaft 253. The connecting shaft 253 acts as both an "inner guide rod" for the spring and restricts the spring to extend and contract only axially; even if the system vibrates, the spring will not jump out laterally, ensuring that the tensioning action is always in the vertical direction and avoiding lateral force interference with the synchronous pulley 210.

[0039] When the synchronous pulley 210 is tensioned by moving upwards, if it is only guided by the elastic element 252, the pulley axle may rotate and wobble, causing the belt to run off-track. Therefore, as an optional implementation, the tensioning assembly 25 also includes a slide rail 254 and a second slider 255; the slide rail 254 is fixedly mounted on the mounting platform 24; the second slider 255 is slidably connected to the slide rail 254 and fixedly connected to the connecting body 2511. The slide rail 254 is fixed on the mounting platform 24, and the connecting body 2511 cooperates with the slide rail 254 through the second slider 255. The slide rail 254-slider pair forces the synchronous pulley 210 shaft to only move in a pure linear motion, eliminating rotational degrees of freedom; the belt centerline always coincides with the track centerline, avoiding belt rubbing against the track during tensioning.

[0040] The top synchronous pulley 210 needs to bear both the belt tension and the rotational load of the detection component 218. If the bearing arrangement is not reasonable, the shaft 216 is prone to bending. Therefore, as an optional implementation, the lifting mechanism 21 also includes a shaft 216 and a bearing; the shaft 216 is coaxially arranged and fixedly connected to the synchronous pulley 210 on the mounting platform 24; the connecting body 2511 has a transversely arranged through hole 2513 for the shaft 216 to pass through; the bearing is sleeved on the shaft 216 and installed in the through hole 2513. The shaft 216 and the synchronous pulley 210 are coaxially fixedly connected, and the connecting body 2511 has a transverse through hole 2513, in which the bearing is installed. The inner ring of the bearing rotates with the shaft 216, and the outer ring is fixed to the connecting body 2511; in this way, the tensioning component 25 does not support a "cantilever shaft", but a simply supported beam structure with "support at both ends", which significantly reduces the deflection of the shaft, makes the synchronous pulley 210 run more smoothly, and makes the meshing of the belt teeth and the pulley teeth more uniform.

[0041] When one side of the belt breaks, that side loses traction, while the other side continues to operate, causing the platform 3 to tilt instantly, posing a high risk of goods slipping. Therefore, as an optional implementation, the lifting mechanism 21 also includes a rotating shaft 216 and a detection component 218 for detecting whether the synchronous belt 211 is broken; the rotating shaft 216 is coaxially arranged and fixedly connected to the synchronous pulley 210 on the mounting platform 24; the detection component 218 includes a detector mounted on the mounting platform 24 and a detection plate mounted on one end of the rotating shaft 216; the detector is used to detect the rotation speed of the detection plate; wherein, when the detectors in the two sets of lifting mechanisms detect different rotation speeds of the detection plate, the detection component 218 determines that the synchronous belt 211 has broken. The detection plate is fixed to the outer end of the rotating shaft 216 of the top synchronous pulley 210; the detector reads the rotation speed of the detection plate. During normal operation, the speeds of the detection plates in the two sets of lifting mechanisms 21 are consistent; if one side of the belt breaks, the corresponding synchronous pulley 210 stops rotating, and the speed of the detection plate drops suddenly. The system immediately identifies belt breakage by detecting speed difference, triggering an emergency stop or brake to control tilting risks at an early stage. Since the detection plate is installed at the top opening, inspectors can also visually observe whether the belt has stopped, achieving dual confirmation through a combination of manual and automatic methods.

[0042] If the detection plate is a smooth disc, the detector needs to continuously identify the edges, which is easily obstructed by dust, leading to missed detections. Therefore, as an optional implementation, the detection plate includes a detection body and multiple detection heads protruding outward from the detection body; the multiple detection heads are evenly distributed circumferentially around the periphery of the detection body. The multiple protruding detection heads evenly distributed along the outer edge of the detection plate form a "toothed disc" appearance. The detector only needs to identify the pulses passing through the detection heads; even if some detection heads are obstructed by dust, the remaining detection heads can still generate a sufficient pulse sequence. The evenly distributed circumferential distribution ensures multiple samplings within one rotation, improving the system's ability to recognize low-speed or intermittent motion and further reducing the probability of missed detections.

[0043] like Figure 2 As shown, the second aspect of this utility model provides the following technical solution: an intelligent warehousing equipment, including a horizontal moving device 1 and a lifting device 2 as described above, wherein the lifting device 2 is installed on the horizontal moving device 1, thereby realizing the horizontal and vertical movement of the platform 3.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
