Description

Technical Field

[0001] This application belongs to the field of industrial automation equipment technology, specifically relating to an automatic line-hanging trolley device applied to a curved monorail. Background Technology

[0002] To meet the material handling needs between workstations in a production line layout, especially when aluminum rail lifters have curved sections and complex structures, traditional mechanical methods often cannot rely solely on pneumatic or electric systems to complete the task. Conventional power supply via sliding contact lines and lifter claw control are typically insufficient for such complex scenarios. For example, most current curved lifters use sliding contact lines for power, and their mechanisms usually rely on high-cost components such as electric actuators to achieve lifter movement, making it impossible to use pneumatic cylinders for clamping and lifting complex workpieces. Furthermore, conventional trolleys lack structures to prevent scratching the aluminum rails; when the trolley tilts forward or backward, the trolley frame may scratch the rails, posing a safety hazard.

[0003] To address the above issues, this application designs an automatic cable-attaching trolley device for curved monorails to ensure that electrical cables and air pipes can be flexibly dragged, thereby guaranteeing the smooth operation of the equipment. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this application designs an automatic cable-hanging trolley device for curved monorails, which avoids scratching the aluminum rail when the trolley tilts forward or backward, while ensuring that electrical cables and air pipes can be dragged flexibly, thereby ensuring the smooth realization of the equipment's functions.

[0006] This application provides an automatic track-attaching trolley device for curved monorails, comprising: a trolley frame including a top plate, a bottom plate, and connecting columns connected to the top plate and the bottom plate respectively, with a gap space between the top plate, the bottom plate, and the connecting columns for clamping the track; a load-bearing wheel assembly mounted on the top plate, with the wheel surface of the load-bearing wheel assembly in rolling contact with the upper surface of the track for supporting the vertical load of the trolley; an anti-tilt wheel assembly mounted on the bottom plate, with the wheel surface of the anti-tilt wheel assembly in rolling contact with the lower surface of the track for pressing the track and preventing the trolley from tipping over; lateral limiting wheels positioned opposite each other on the top plate and the bottom plate, with the wheel surface of the lateral limiting wheels in rolling contact with the vertical sidewall of the track for limiting the lateral deviation of the trolley and guiding it to travel along the track; and track anti-scratch guide members respectively mounted on the front and rear ends of the trolley frame along the direction of travel.

[0007] In some possible embodiments, the load-bearing wheel assembly includes: a load-bearing wheel pin, which is disposed through the connecting column; and a load-bearing wheel, which is mounted on the top plate via the load-bearing wheel pin.

[0008] In some possible embodiments, the anti-roll wheel assembly includes: an anti-roll wheel retainer mounted on the base plate; an anti-roll wheel mounted on the anti-roll wheel retainer; an anti-roll wheel pin pendant passing through the anti-roll wheel retainer and connecting to the anti-roll wheel; retaining rings mounted at both ends of the anti-roll wheel pin; and snap rings mounted at the end of the anti-roll wheel pin, which, in conjunction with the anti-roll wheel pin and retaining rings, secure the front and rear anti-roll wheels to the anti-roll wheel retainer.

[0009] In some possible embodiments, the system may also include: an air hose / cable hook mounted on the anti-roll wheel retainer for suspending cables and air hoses; and an adapter ring connected to the air hose / cable hook to provide vertical freedom for the cables and air hoses.

[0010] In some possible embodiments, the air hose cable hook is a magnetic hook.

[0011] In some possible implementations, the adapter ring is rotatably connected to the air hose cable hook to allow the cable and air hose to swing horizontally.

[0012] In some possible embodiments, the adapter ring is provided with a locking mechanism to restrict the movement of the adapter ring relative to the air cable hook.

[0013] In some possible embodiments, the track anti-scratch guide is a nylon guide, and the contact surface of the nylon guide is an arc surface.

[0014] In some possible embodiments, the outer surface of the lateral limiting wheel is provided with a wear-resistant coating.

[0015] In some possible embodiments, the connecting column is detachably connected to the top plate and the bottom plate.

[0016] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects:

[0017] This application provides an automatic track-setting trolley device for curved monorails. Through a comprehensive design integrating the trolley frame, load-bearing wheel assembly, anti-tilt wheel assembly, lateral limiting wheels, and track anti-scratch guide components, it achieves multiple technical advantages. First, the synergistic effect of the load-bearing wheel assembly and the anti-tilt wheel assembly significantly improves the stability of the trolley during curved operation by supporting the vertical load and pressing against the lower surface of the track, preventing the risk of overturning due to uneven load. Second, the lateral limiting wheels, symmetrically distributed on the top and bottom plates, precisely limit lateral deviation by contacting the vertical sidewalls of the track, ensuring the trolley always travels along the predetermined path and reducing the possibility of derailment. Furthermore, the track anti-scratch guide components are installed at the front and rear ends of the frame. Their contact surfaces are made of low-friction materials and feature a rounded design, preventing scratches on the aluminum rail surface while reducing running resistance. The overall structure is compact and modular, making it particularly suitable for complex industrial environments with limited space, balancing efficiency and safety.

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0032] The following reference Figures 1 to 2 This application describes an automatic line-attaching trolley device for curved monorails, according to some embodiments thereof.

[0033] Please see Figures 1 to 2 The automatic track-setting trolley device for curved monorails provided in some embodiments of this application includes: a trolley frame 100, including a top plate 110, a bottom plate 120, and connecting columns 130 respectively connected to the top plate 110 and the bottom plate 120, with a gap space between the top plate 110, the bottom plate 120, and the connecting columns 130 for clamping the track; and a load-bearing wheel assembly 200, mounted on the top plate 110, with the wheel surface of the load-bearing wheel assembly 200 in rolling contact with the upper surface of the track for supporting the trolley vertically. Load; Anti-tilt wheel assembly 300, mounted on base plate 120, the wheel surface of anti-tilt wheel assembly 300 rolls in contact with the lower surface of the track, used to press the track and prevent the trolley from tipping over; Lateral limiting wheel 400, placed opposite each other on top plate 110 and base plate 120, the wheel surface of lateral limiting wheel 400 rolls in contact with the vertical side wall of the track, used to limit the lateral deviation of the trolley and guide it to travel along the track; Track anti-scratch guide 500, respectively mounted on the front end and rear end of the trolley frame 100 along the direction of travel.

[0034] In this embodiment, the load-bearing wheel 210 is connected to the trolley frame 100 via a pin and is responsible for the longitudinal load-bearing of the trolley. Eight lateral limiting wheels 400 are connected to the trolley frame 100 to control the lateral clearance between the trolley and the aluminum rail, ensuring the stable operation of the trolley on the track. The front and rear anti-tilt wheels 320 are fixed by two pins on two anti-tilt wheel retainers 310 screwed onto the trolley frame 100, four lateral limiting retaining rings 340, and four retaining springs 350, effectively eliminating the risk of the trolley tipping over. Four track anti-scratch guides 500 are connected to the trolley frame 100 to prevent the trolley from scratching the aluminum rail in a slightly tilted state, further improving safety.

[0035] This design not only ensures the high stability and safety of the trolley during operation, but also effectively avoids damage to the aluminum rails, improving the overall system's reliability and durability.

[0036] In some embodiments, the top plate 110 has an opening in the middle, and the lower wheel surface of the bearing wheel 210 is located in the opening of the top plate 110 and rolls in contact with the upper surface of the track. The bottom plate 120 also has an opening in the middle, and the upper wheel surface of the anti-tilt wheel 320 passes through the opening of the bottom plate 120 and rolls in contact with the lower surface of the track.

[0037] In some embodiments, the load-bearing wheel assembly 200 includes: a load-bearing wheel pin 220, which is disposed through the connecting post 130; and a load-bearing wheel 210, which is mounted on the top plate 110 via the load-bearing wheel pin 220.

[0038] In this embodiment, the load-bearing wheel is connected to the top plate 110 via a load-bearing wheel pin 220. The pin is made of elastic steel, allowing the wheel to deflect at a certain angle around the pin's axis. The end of the pin is secured with a nut; after removing the nut, the pin can be pulled out for quick replacement of the worn load-bearing wheel. This pin structure not only distributes the stress of vertical loads, extending the service life of the load-bearing wheel, but also simplifies the maintenance process through its detachable design. When the load-bearing wheel wears out due to long-term use, only the wheel body needs to be replaced without disassembling the entire frame, significantly reducing maintenance costs and time.

[0039] In some embodiments, the anti-roll wheel assembly 300 includes: an anti-roll wheel retainer 310 mounted on a base plate 120; an anti-roll wheel 320 mounted on the anti-roll wheel retainer 310; an anti-roll wheel pin 330 passing through the anti-roll wheel retainer 310 and connecting to the anti-roll wheel 320; a retaining ring 340 mounted on both ends of the anti-roll wheel pin 330; and a retaining spring 350 mounted on the end of the anti-roll wheel pin 330, which, in conjunction with the anti-roll wheel pin 330 and the retaining ring 340, secures the front and rear anti-roll wheels 320 to the anti-roll wheel retainer 310.

[0040] In this embodiment, the anti-roll wheel 320 is connected to the anti-roll wheel cage 310 via an anti-roll wheel pin 330. The pin passes through both ends of the cage, and a retaining ring 340 and a snap ring 350 are sequentially installed at the ends. The retaining ring 340 restricts the axial displacement of the pin, and the snap ring 350 provides elastic locking force. The middle section of the pin has a threaded section, and the contact pressure between the anti-roll wheel and the track can be changed by adjusting the nut.

[0041] The anti-tilt wheel pin 330 passes through the cage and the anti-tilt wheel. A dual locking mechanism, consisting of a retaining ring 340 and a snap ring 350, prevents axial movement of the pin during dynamic operation, ensuring the anti-tilt wheel remains tightly fitted to the lower surface of the track. The adjustable nut at the pin end allows for dynamic adjustment of the contact pressure between the anti-tilt wheel and the track, adapting to stability requirements under different load conditions. Furthermore, the mechanical limit design significantly reduces the risk of component loosening or failure, ensuring the reliability of the device during long-term high-load operation.

[0042] In some embodiments, the system further includes: an air hose and cable hook 600, mounted on the anti-roll wheel retainer 310, for suspending cables and air hoses; and an adapter ring 700, connected to the air hose and cable hook 600, providing vertical freedom for the cables and air hoses.

[0043] In this embodiment, the air hose and cable hook 600 provides a connection point for the trolley to tow cables and air hoses, granting them a degree of freedom in one direction to ensure that the cables and air hoses are not excessively stretched during movement. The adapter ring 700 is responsible for providing the vertical cable and air hose laying freedom, ensuring that they can be flexibly adjusted in position under different working conditions. After assembly, the cable-hanging trolley is attached to the aluminum rail and works in conjunction with the traveling mechanism to jointly realize the functions of the power system and electrical control system. Optionally, the adapter ring 700 and the air hose and cable hook 600 can be connected via a universal joint.

[0044] In some embodiments, the air hose cable hook 600 is a magnetic hook.

[0045] In this embodiment, the magnetic design allows the cable connector to be quickly positioned and firmly attached to the hook surface, significantly reducing installation time, especially suitable for applications requiring frequent adjustments. During equipment vibration or sudden stops, the magnetic force effectively prevents the cable from accidentally coming loose, improving operational safety. Optionally, a rubber layer can be applied to the magnetic hook's attachment surface to increase friction.

[0046] In some embodiments, the adapter ring 700 is rotatably connected to the airway cable hook 600 to allow the cable and airway to swing horizontally.

[0047] In some embodiments, the adapter ring 700 is provided with a locking mechanism for limiting the movement of the adapter ring 700 relative to the air cable hook 600.

[0048] In this embodiment, the locking mechanism is a knob design, with a built-in threaded rod that engages with the slot of the adapter ring 700. Rotating the knob clockwise presses the threaded rod against the slot, limiting the swing of the adapter ring 700; rotating it counterclockwise releases the locking force, restoring free swing. During high-speed straight-line operation, the operator tightens the locking knob to secure the adapter ring 700, preventing cable swing from interfering with adjacent equipment; before entering a curve, the knob is released to restore the swing function.

[0049] The locking mechanism further balances the needs for flexibility and stability. Using a knob or pin-type locking device, users can select the 700° angle of the fixed adapter ring according to actual working conditions, preventing excessive cable swaying during high-speed movement or sudden load changes. This design retains the flexibility of cable dragging while providing rigid support when needed, making it particularly suitable for scenarios requiring high cable positioning accuracy. Furthermore, the locking mechanism effectively prevents cable loosening due to accidental contact or impact, enhancing operational safety.

[0050] In some embodiments, the track anti-scratch guide 500 is a nylon guide, and the contact surface of the nylon guide is an arc surface.

[0051] In this embodiment, the use of a nylon track anti-scratch guide 500 and a rounded contact surface design protects the surface of the aluminum rail. The low-friction properties of nylon significantly reduce the running resistance between the guide and the rail, while its excellent wear resistance and impact resistance extend the service life of the guide. The rounded contact surface prevents sharp edges from scratching the aluminum rail, and even when the frame is slightly tilted, the guide's preferential contact disperses pressure, avoiding the risk of the metal frame directly scratching the rail.

[0052] In some embodiments, the outer surface of the lateral limiting wheel 400 is provided with a wear-resistant coating.

[0053] In this embodiment, the wear-resistant coating can be plasma-sprayed tungsten carbide. The lateral limiting wheel 400 makes rolling contact with the track sidewall through the coating. The coefficient of friction decreases under the action of the wear-resistant coating, which greatly reduces the wear rate caused by friction between the wheel and the track sidewall, thereby extending the replacement cycle of the limiting wheel and reducing maintenance costs.

[0054] In some embodiments, the connecting column 130 is detachably connected to the top plate 110 and the bottom plate 120.

[0055] This solution significantly reduces the cost of production line upgrades or equipment modifications, while simplifying warehouse management and reducing the types of spare parts. Furthermore, the modular connection method supports rapid assembly and disassembly, enhancing the equipment's flexible deployment capabilities and making it suitable for industrial scenarios involving mixed production of multiple specifications.
