Description

Technical Field

[0001] This utility model relates to the field of cable handling technology, and in particular to a DC cable transport vehicle. Background Technology

[0002] In the fields of power engineering and cable laying, the transportation and handling of cable reels has always faced the dual challenges of efficiency and safety. Raw materials and finished products of wires and cables are generally stored and transferred using cable reels of different specifications. Traditional cable transportation equipment mostly uses fixed forklift structures. Large cable manufacturing companies typically need to equip themselves with handling equipment of different specifications to accommodate the handling of reels of varying sizes. During loading and unloading, the lack of adjustable support devices makes it difficult to stably support cable reels of different diameters, and poor adaptability increases operational risks.

[0003] Therefore, a DC cable transport vehicle is needed that can adapt to cable reels of different diameters and solve the problem of handling cable reels. Utility Model Content

[0004] To solve the problem of transporting cable reels of different diameters, this utility model provides a DC cable transport vehicle.

[0005] This utility model provides a DC cable transport vehicle, including a central control vehicle body. The front end of the central control vehicle body is provided with a vertically erected support frame. The bottom end of the support frame is provided with a fork assembly. The fork assembly includes a traveling fork and a lifting fork mounted on the traveling fork. The lifting fork is connected to a drive assembly and a centering assembly. The drive assembly can drive the lifting fork to move vertically upward, and the centering assembly can drive the lifting fork to move towards the center. The sidewalls of the lifting forks on both sides facing the center form a V-shaped support surface, which is used to support and support a horizontally placed cable reel.

[0006] Furthermore, the driving assembly includes a driving cylinder connected to the support frame, a connecting block fixedly connected to the output end of the driving cylinder, the connecting block fixedly mounted on the driving plate, the connecting block slidably mounted on the limiting post, driving sliders on both sides of the driving plate, and driving guide rails that slidably cooperate with the driving sliders on both sides of the support frame.

[0007] Furthermore, the centering assembly includes a centering guide rail positioned horizontally on the front side of the drive plate, a centering slider slidably connected to the centering guide rail, a threaded block fixedly connected to the centering slider, a horizontally positioned screw connected to the threaded block, and a centering motor for driving the screw to rotate connected to one end of the screw via a coupling. Two of each of the centering guide rail, centering slider, threaded block, screw, and centering motor are provided.

[0008] Furthermore, the drive plate is provided with a limiting plate, the screw passes through the limiting plate, and the limiting plate can abut against the threaded block.

[0009] Furthermore, the front end of the lifting fork is provided with a telescopic component, and the front end of the lifting fork is sleeved with a telescopic fork sleeve. The telescopic component includes a telescopic cylinder, the output end of which is located at the end of the telescopic fork sleeve. The lifting fork is provided with a partition, and the telescopic cylinder is located on the partition.

[0010] Furthermore, the front end of the telescopic fork sleeve is provided with a folding assembly, which includes a right-angle arm connected by a rotating shaft and a swing motor that drives the rotating shaft to rotate.

[0011] Furthermore, a slot is formed on the right-angle arm, and a cylindrical rod is connected to the slot through a shaft. After the right-angle arm is extended by the swing motor, the cylindrical rod faces the support frame.

[0012] Furthermore, a safety limit rod is connected to one side of the support frame, and the safety limit rod is provided with multiple limit protrusions. A movable rod is hinged to the drive plate, and the movable rod can rotate along the horizontal plane and contact the safety limit rod.

[0013] Furthermore, the upper surface of the lifting fork is provided with a wing assembly, the wing assembly includes a wing plate, the cross-section of the wing plate is obtuse-angled, the wing plate is hinged to the outer wall of the lifting fork via a pivot, and after the wing plate unfolds outward along the pivot, the wing plates on both sides form a V-shaped extension surface.

[0014] Furthermore, the length of the lifting fork is greater than the length of the traveling fork, and the traveling fork is equipped with traveling wheels at the bottom.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] 1. This utility model proposes a DC cable transport vehicle with an adaptive support function. The V-shaped support surfaces of the lifting forks on both sides form a linkage structure with the centering component. The inclination angle of the V-shaped surfaces is adapted to the cylindrical shape of the cable reel. The screw transmission mechanism of the centering component can drive the lifting forks to move towards the center. This solves the compatibility problem of traditional fixed forks with cable reels of different diameters.

[0017] 2. The telescopic fork sleeve at the front end of the lifting fork of this utility model can achieve a certain distance of extension length adjustment through the telescopic cylinder. With the right-angle arm structure of the folding component, when the swing motor drives the right-angle arm to unfold 90°, the cylindrical rod in the slot forms a limiting fulcrum. When the telescopic fork sleeve is retracted, the right-angle arm pushes the cable reel to move inward. At the same time, the right-angle arm and the V-shaped support surface form a three-dimensional protective frame to ensure transportation safety.

[0018] 3. The limiting protrusion on the safety limiting rod of this utility model forms a safety limiting structure with the movable rod of the drive plate, further ensuring transportation safety. The V-shaped extension surface formed after the wing assembly unfolds and the supporting surface constitute upper and lower protective barriers, which on the one hand can be used for transporting cable reels with larger diameters, and on the other hand provides safer protection and limiting for small cable reels.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Reference Figure 1 This embodiment of a DC cable transport vehicle includes a central control vehicle body 1. The front end of the central control vehicle body 1 is provided with a vertically erected support frame 2. The bottom end of the support frame 2 is provided with a fork assembly 3. The fork assembly 3 includes a traveling fork 301 and a lifting fork 302 disposed on the traveling fork 301. The lifting fork is connected to a drive assembly 4 and a centering assembly 5. The drive assembly 4 can drive the lifting fork 302 to move vertically upward, and the centering assembly 5 can drive the lifting fork 302 to move towards the center. The side walls of the lifting forks 302 on both sides facing the center form a V-shaped support surface 303. The support surface 303 is used to support the horizontally placed cable reel 10.

[0037] Reference Figure 2 and Figure 3 The drive assembly 4 includes a drive cylinder 401 connected to the support frame 2. The output end of the drive cylinder 401 is fixedly connected to a connecting block 402. The connecting block 402 is fixedly mounted on the drive plate 403 and slidably mounted on the limiting post 404. The drive plate 403 has drive sliders 405 on both sides, and the support frame 2 has drive guide rails 406 on both sides that slidably cooperate with the drive sliders 405.

[0038] The drive assembly 4 employs a combination of cylinder and guide rail slider transmission. When the output end of the drive cylinder 401 extends or retracts, the connecting block 402, which is fixedly connected to it, slides linearly along the limiting post 404. The limiting post 404 provides guidance for the connecting block 402. The linear motion of the connecting block 402 is synchronously transmitted to the drive plate 403. The drive sliders 405 on both sides of the drive plate 403 and the drive guide rails 406 on the support frame 2 form a dovetail groove fit structure. This design ensures the smooth movement of the drive plate 403 in the vertical direction and prevents the sliders from derailing through the trapezoidal cross section of the guide rails.

[0039] Reference Figure 2The centering assembly 5 includes a centering guide rail 501 horizontally positioned on the front side of the drive plate 403. A centering slider 502 is slidably connected to the centering guide rail 501. A threaded block 503 is fixedly connected to the centering slider 502. A horizontally positioned screw 504 is connected to the threaded block 503. One end of the screw 504 is connected to a centering motor 505 that drives the screw 504 to rotate via a coupling. Two of each of the centering guide rail 501, centering slider 502, threaded block 503, screw 504, and centering motor 505 are provided. A limiting plate 506 is provided on the drive plate 403. The screw 504 passes through the limiting plate 506, and the limiting plate 506 can abut against the threaded block 503.

[0040] The centering component 5 employs a twin-screw 504 drive structure. When the centering motor 505 drives the screw 504 to rotate, the threaded block 503, which cooperates with the screw 504, converts the rotational motion into linear motion, thereby driving the centering slider 502 to slide along the centering guide rail 501. The surface of the centering guide rail 501 is chrome-plated to improve wear resistance, and its internal lubrication grooves can store grease, enabling long-term maintenance-free operation. The limiting plate 506 on the drive plate 403 forms a mechanical limit with the threaded block 503. When the threaded block 503 moves to its limit position, it abuts against the limiting plate 506, triggering a proximity switch, such as a Hall sensor, set on the limiting plate 506 to achieve electrical limit.

[0041] The drive assembly 4 is located on the back side of the drive board 403, and the centering assembly 5 is located on the front side of the drive board 403.

[0042] The lifting fork 302 has a telescopic component 6 inside its front end. The front end of the lifting fork 302 is sleeved with a telescopic fork sleeve 601. The telescopic component 6 includes a telescopic cylinder 602. The output end of the telescopic cylinder 602 is located at the end inside the telescopic fork sleeve 601. The lifting fork 302 has a partition 603 inside it. The telescopic cylinder 602 is mounted on the partition 603.

[0043] The telescopic assembly 6 adopts a built-in cylinder structure. The telescopic cylinder 602 is fixed to the partition 603 inside the lifting fork 302, and its output end is connected to the inner end of the telescopic fork sleeve 601. When the telescopic cylinder 602 is working, the telescopic fork sleeve 601 slides along the inner wall of the lifting fork 302 to extend or retract. The mating surface between the lifting fork 302 and the telescopic fork sleeve 601 adopts a rectangular guide rail structure. Each of the four sides of the guide rail is equipped with PTFE sliding plates, which ensures guidance while reducing sliding resistance. The partition 603 divides the interior of the lifting fork 302 into front and rear chambers. The rear chamber is used to house the air lines of the telescopic cylinder 602, while the front chamber serves as the sliding space for the telescopic fork sleeve 601. The partition 603 provides support for the telescopic cylinder 602.

[0044] Reference Figure 4The telescopic fork sleeve 601 has a folding component 7 at its front end. The folding component 7 includes a right-angle arm 701 connected by a rotating shaft and a swing motor 702 that drives the rotating shaft to rotate.

[0045] Reference Figure 4 and Figure 5 A slot is formed on the right-angle arm 701, and a cylindrical rod 703 is connected in the slot through a shaft. After the swing motor 702 drives the right-angle arm 701 to unfold, the rod 703 faces the support frame 2.

[0046] The folding assembly 7 employs a pivot 902 structure driven by a swing motor 702. The swing motor 702 is connected to the rotating shaft via a reducer. When the motor drives the rotating shaft to rotate, the right-angle arm 701, which is fixed to it, rotates synchronously. A cylindrical rod 703 is mounted in the slot of the right-angle arm 701 via a shaft. The surface of the rod 703 is covered with a polyurethane buffer layer. When the right-angle arm 701 is extended to the horizontal position, the axis of the rod 703 is parallel to the axis of the cable reel 10. At this time, the rod 703 and the V-shaped support surface 303 form a three-point support structure. An angle encoder is provided on the rotating shaft to monitor the rotation angle of the right-angle arm 701. When the angle reaches a preset value, the motor triggers the electromagnetic brake to lock, ensuring that the rod 703 maintains a stable position during operation.

[0047] Reference Figure 2 A safety limit rod 8 is connected to one side of the support frame 2. The safety limit rod 8 is provided with multiple limiting protrusions 801. A movable rod 802 is hinged to the drive plate 403. The movable rod 802 can rotate along the horizontal plane and contact the safety limit rod 8.

[0048] During the lifting and lowering of the drive plate 403, the movable rod 802, hinged to the drive plate 403, moves synchronously with the drive plate 403. By manually rotating the movable rod 802 to the position of contacting the safety limit rod 8, the limit protrusions 801 are arrayed on the safety limit rod 8 to form a multi-level limit, preventing the drive assembly 4 from suddenly losing power support and ensuring safety during transportation.

[0049] Reference Figure 3 The upper end face of the lifting fork 302 is provided with a wing assembly 9. The wing assembly 9 includes a wing plate 901. The cross-sectional shape of the wing plate 901 is obtuse. The wing plate 901 is hinged to the outer wall of the lifting fork 302 through a pivot 902. After the wing plate 901 is extended outward along the pivot 902, the wing plates 901 on both sides form a V-shaped extension surface.

[0050] The length of the lifting fork 302 is greater than the length of the traveling fork 301, and the traveling fork 301 is provided with a traveling wheel 304 at the bottom.

[0051] The wing assembly 9 adopts a hinged structure with a pivot 902. The obtuse-angled cross-section design of the wing plate 901 allows it to form a continuous V-shaped extension surface with the V-shaped support surface 303 of the lifting fork 302 after unfolding. The included angle of this extension surface is consistent with the included angle of the support surface 303, ensuring stable support for cable reels 10 of different diameters. The wing plate 901 is connected to the outer wall of the lifting fork 302 via the pivot 902. When it needs to be unfolded, the wing plate 901 is manually flipped to rotate around the pivot 902.

[0052] During operation, after the equipment is started, the PLC automatically performs self-checks on the drive cylinder 401, centering motor 505, swing motor 702, and sensor signals. The operator inputs the diameter parameter of the cable reel 10, and the system automatically adjusts the height and spacing of the lifting forks 302, retracts the telescopic fork sleeve 601, and folds the right-angle arm 701. Next, the vehicle body is manipulated to align the traveling forks 301 below the cable reel 10. The drive cylinder 401 raises the lifting forks 302, making the V-shaped support surface 303 lower than the axis of the cable reel 10. When the lifting forks 302 contact the cable reel 10, the centering motor 505 drives the forks on both sides to retract, so that the V-shaped surface fits against the cable reel 10 to complete the positioning. Then, the telescopic fork sleeve 601 extends, the right-angle arm 701 unfolds, and the round rod 703 presses against the cable reel 10. The telescopic fork sleeve 601 is then retracted, causing the cable reel 10 to move backward and fall into the support surface 303. Then, the drive cylinder 401 raises the cable reel 10 to a height above the ground. At this point, the movable lever 802 can be manually rotated. If the diameter of the cable reel 10 to be transported is large, the wing plate 901 needs to be manually deployed in advance to form protection. After reaching the unloading position, the drive cylinder 401 lowers the cable reel 10 to near the ground. The folding right-angle arm 701 and the wing plate 901 are released from their limiting positions. The drive cylinder 401 continues to lower the cable reel 10 to the ground. At the same time, the center motor 505 deploys the lifting fork 302. Finally, the telescopic fork sleeve 601 retracts to its initial state.

[0053] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
