Description

Technical Field

[0001] This invention relates to the field of cable tray storage technology, and more specifically to a power cable tray storage device with efficient tray replacement capability. Background Technology

[0002] In traditional power cable stranding processes, there is often a problem with poor equipment scheduling mechanisms. Research has found that the root cause lies in the fact that the cable reel replacement process relies on a fixed docking method of "one machine, one vehicle" with dedicated railcars or manual handling, resulting in a certain amount of idle resources.

[0003] Furthermore, in terms of spatial layout and safety, redundant ground stacking exacerbates space constraints. Based on this, some companies have chosen to adopt a structure similar to a multi-level parking garage for pallet storage. For example, Chinese utility model patent CN220933831U discloses an unmanned pallet loading mechanism for a wire winch, including a pallet storage unit, a loading device for transferring wire reels from the storage unit to the winch, and an AGV (Automated Guided Vehicle) for placing full wire reels on the storage unit and removing empty wire reels from the storage unit. The storage unit includes a frame, several pallet racks for placing wire reels, and a vertical drive unit for driving the racks up and down. The loading device includes a horizontal drive assembly, a tilting assembly mounted on the horizontal drive assembly, and a pushing assembly mounted on the tilting assembly. The storage tray can simultaneously load empty and full wire reels. The storage and unloading of the wire reels are carried out during the normal production process of the frame stranding machine, without interrupting the reel changing cycle, thus improving the efficiency of reel changing and achieving seamless connection between the storage tray, the upper reel, and the frame stranding machine. However, when supplying wire reels, the entire storage tray needs to move, which is relatively energy-intensive. Furthermore, the stability of this type of three-dimensional garage-style storage tray is difficult to control, and it affects the improvement of the reel positioning speed during subsequent wire reel transfer.

[0004] Research has revealed that this type of multi-level garage-style storage tank can actually serve as a transfer station to adjust the spatial position of the cable reels. Therefore, the focus of research is on how to design an efficient cable reel changing storage device for power cable frame stranding machines based on this concept. Summary of the Invention

[0005] To solve the above problems, the present invention provides the following technical solution: a power cable frame stranding machine storage device with efficient reel replacement, comprising:

[0006] Multiple storage racks are arranged vertically at intervals, and adjacent storage racks are connected by connecting frames. The storage racks are used to store wire reels.

[0007] A receiving and transmitting component, located on one side of the plurality of storage tray racks, is used to receive reels from different storage tray racks and transpose the reels to a designated position;

[0008] A horizontal conveying assembly is located between the storage rack and the receiving and conveying assembly. The number of horizontal conveying assemblies is the same as the number of storage racks, so that they are installed on one side of the storage racks respectively.

[0009] A robotic arm is used to grasp the reel located at the designated position and deliver it to the reel-changing assembly;

[0010] The plate changing assembly is mounted on a railcar, which can be moved to the location of the frame winch.

[0011] The storage tray frame is equipped with multiple conveying rollers that rotate.

[0020] At least two symmetrically arranged adjusting rods are fixed to both sides of the conveyor frame, and each adjusting rod is threaded with a screw.

[0021] A guide plate is fixed to the corresponding screw. One end of the guide plate near the receiving and transmitting assembly extends beyond the transmitting frame, and this end has a support groove corresponding to the support bar.

[0022] Furthermore, as a preferred embodiment, the center of the support seat is also rotatably provided with multiple conveying rollers.

[0031] Compared with the prior art, the present invention provides a power cable frame stranding machine storage device with efficient reel replacement, which has the following advantages:

[0032] 1. In this invention, a reel-changing assembly mounted on a railcar autonomously moves to the frame winch location, enabling the reel-changing operation. Furthermore, a single railcar can serve multiple frame winches, demonstrating strong resource reusability.

[0033] 2. In this invention, the telescopic rod retraction action allows the support bar to be embedded in the support groove, thereby using the horizontal conveying component to stabilize the corresponding bearing seat and eliminate the risk of coil offset or tipping.

[0035] 4. In this invention, the vertically layered design of the storage rack saves space, and the receiving and transmitting components adopt a three-dimensional garage-like structure to support layered receiving and transmitting.

[0036] 5. In this invention, the double guide cone structure of the reel changing assembly, combined with the elastic element and the cam-driven centering head, enables rapid and accurate centering of the reel, effectively eliminating the risk of misalignment. Attached Figure Description

[0044] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0045] Example: In this embodiment of the invention, please refer to... Figures 1-6 A power cable frame stranding device with efficient reel replacement is provided, comprising multiple reel racks 1 arranged vertically at intervals. The reel racks 1 adjacent to each other are connected by a connecting frame 2. The reel racks 1 are used to store wire reels. The multi-layer independent reel racks 1 are arranged vertically in a layered layout through the connecting frame 2. Each reel rack 1 is equipped with an actively rotating conveyor roller 11 to realize automatic sliding and positioning of the wire reel. Furthermore, safety nets or safety frames are evenly distributed on the front and rear sides of each reel rack 1.

[0046] A receiving and conveying component 4 is provided on one side of the storage rack 1. This component receives reels from different storage racks 1 and repositions them to designated locations. Specifically, the receiving and conveying component 4 can receive reels of different heights and reposition them to designated locations on the side of the receiving and conveying component 4 away from the storage rack 1. The side of the receiving and conveying component 4 away from the storage rack 1 has ample operating space, facilitating subsequent reel transfer. More specifically, the receiving and conveying component 4 employs a three-dimensional parking garage-like structure to achieve layered receiving and conveying of reels, a mature technology that will not be elaborated upon here. Its core value lies in achieving multi-station collaborative transfer through adjustable support seats 41, providing a stable base for the positioning components. That is, the receiving and conveying component 4 includes multiple spatially adjustable and horizontally level support seats 41, each of which is equipped with two symmetrically arranged positioning components 5.

[0047] The positioning component 5 includes:

[0048] The limiting seat 51 is fixed on the bearing seat 41;

[0049] The slide block 52 is slidably disposed on the limiting seat 51 and is driven by the telescopic rod 54;

[0050] The claw 53 is V-shaped and fixed on the slide block 52. The V-shaped claw 53 can automatically adapt to different diameter coils. The claw 53 completes radial clamping under the drive of the telescopic rod 54.

[0051] Support bar 55 is fixed to one side of the slide 52 and is used to support the horizontal conveying assembly 3.

[0052] Specifically, a horizontal conveying assembly 3 is provided between the storage rack 1 and the receiving and conveying assembly 4. The number of horizontal conveying assemblies 3 is the same as the number of storage racks 1, so that they are installed on one side of the storage rack 1 respectively. The horizontal conveying assembly 3 has a unique function as a temporary transfer station. More specifically, the horizontal conveying assembly 3 includes:

[0053] A conveyor frame 31, on which a conveyor belt 32 is mounted;

[0054] At least two symmetrically arranged adjusting rods 33 are fixed to both sides of the conveyor frame 31, and each adjusting rod 33 is threaded with a screw.

[0055] The guide plate 34 is fixed to the corresponding screw. The end of the guide plate 34 near the receiving and conveying assembly 4 extends beyond the conveying frame 31, and the end is provided with a support groove 35 corresponding to the support bar 55. That is to say, the distance between the two guide plates 34 can be quickly adjusted by rotating the screw to match the coils of different diameters. Furthermore, the two guide plates 34 are symmetrically arranged to ensure that the coil is always in the center position of the conveyor belt 32 and to prevent deviation.

[0056] Therefore, during implementation, after the positioning component 5 reaches the designated position, the telescopic rod 54 first retracts to make the support bar 55 fit into the support groove 35, thereby using the horizontal transmission component 3 to stabilize the corresponding bearing seat 41. Then, when the horizontal transmission component 3 transfers the coil to the bearing seat 41, the telescopic rod 54 extends to make the claw 53 radially clamp the coil.

[0057] It is worth mentioning that the support groove 35 at the end of the guide plate 34 physically engages with the support bar 55 of the positioning component 5. When the telescopic rod 54 retracts, the support bar 55 precisely engages with the support groove 35, effectively providing a rigid support point for the carrier 41 and eliminating the risk of swaying or shifting of the coil during transmission. This ensures that the carrier 41 is fully stabilized when the coil is transferred from the horizontal transmission component 3 to the carrier 41, avoiding overturning problems caused by suspension or uneven force.

[0058] In this embodiment, a robotic arm 6 is installed on the side of the receiving and transmitting component 4 away from the storage rack 1. This robotic arm 6 is used to grab the reel located at the designated position and deliver it to the reel-changing component 7. The reel-changing component 7 is mounted on a railcar 8, which can move to the location of the frame winch 9. The robotic arm 6 loads the reel onto the reel-changing component 7, and the railcar 8 can then carry the reel to the frame winch 9 for reel changing. A single railcar 8 can serve multiple frame winches 9, achieving resource reuse.

[0059] Furthermore, a plurality of conveying rollers 11 are rotatably arranged in the middle of the bearing seat 41, which facilitates the delivery of the wire reel on the bearing seat 41 to the horizontal conveying assembly 3, thereby realizing the recycling of the wire reel.

[0060] The disk changing assembly 7 includes:

[0061] The height adjustment mechanism 71 is fixed on the railcar 8 and has a height adjustment end;

[0062] Support base 72 is fixed to the height adjustment end;

[0063] The adjusting seat 73 is rotatably mounted on the support seat 72 and is driven to rotate by the first motor 74.

[0064] Furthermore, a limiting cylinder 711 is fixed on the adjusting seat 73, and a first guide cone 76 is fixed on the limiting cylinder 711. A second guide cone 77 is connected to the first guide cone 76 through an elastic member 78. The cone angle of the second guide cone 77 is greater than the cone angle of the first guide cone 76.

[0065] The second guide cone 77 serves as the primary guide, its sharp tip allowing for quick insertion into the center hole of the coil for coarse positioning. The first guide cone 76 forms the secondary guide. Additionally, the elastic element 78 allows the second guide cone 77 to undergo slight displacement upon contact with the coil, absorbing the impact force during robot placement and preventing rigid collisions that could damage the coil or equipment.

[0066] In addition, a plurality of straightening heads 79 are slidably connected to the side of the first guide cone 76 via a return spring;

[0067] In the initial state, each of the straightening heads 79 is housed in the first guide cone 76;

[0068] A cam 710 is rotatably disposed in the first guide cone 76, the cam 710 corresponding to the straightening head 79, and the cam 710 is driven by the second motor 75.

[0069] In other words, the cam 710 is driven to rotate by the second motor 75, and its contour curve pushes the centering head 79 to slide radially out and press against the inner wall of the spool. The rotational motion of the cam 710 is converted into the synchronous radial expansion of the centering head 79, which can correct the tilt or eccentricity of the spool in real time and ensure that its axis is quickly aligned with the spool changing assembly 7.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
