Description

Technical Field

[0001] This utility model relates to the technical field of wire winding and transportation equipment, specifically an anti-shaking wire reel transfer tray. Background Technology

[0002] Currently, in the production and warehousing of cables, optical fibers, and metal wires, wire reels serve as the primary winding and transport carriers, typically handled and placed using fixed supports or simple pallets. In existing technologies, common wire reel transfer devices often use pins, clamping rings, or pressure caps to limit and fix the reel's axis, then use roller supports to allow movement. While this structure provides basic support and transfer, it is prone to swaying and shifting during long-distance movement, frequent vibrations, or when multiple reels are stacked, leading to loosening of the winding, wire stretching, and potential transportation safety hazards.

[0003] In existing wire reel transfer structures, some methods such as threaded tightening, wedge expansion, or elastic grippers are used to lock the inner hole of the wire reel. For example, traditional mechanical tightening devices typically consist of a screw and an expansion sleeve, relying on rotating the screw to drive the expansion sleeve to expand outward, thereby achieving inner hole support. However, such structures suffer from problems such as complex operation, short tightening stroke, and poor locking uniformity; during frequent loading and unloading of wire reels, the operating efficiency is low and the structure suffers severe wear.

[0004] Furthermore, most existing pallets only provide static support and lack anti-sway design for the wire reel. When the pallet moves or is subjected to lateral impact, the wire reel is prone to radial sway and axial displacement due to inertia, causing the edge of the reel to collide with adjacent structures or even detach, seriously affecting transportation stability and operational safety. Although some improved pallets with anti-slip pads or limiting blocks can reduce swaying, they still cannot achieve a stable lock-on of the wire reel's inner hole.

[0005] Therefore, designing a transfer pallet structure that is easy to operate, reliably locked, and effectively prevents the reel from shaking during transportation and handling, while maintaining a compact structure, has become a problem that urgently needs to be solved by those skilled in the art. This utility model addresses the above-mentioned problem by using a mechanical linkage structure between the drive shaft and the expansion joint assembly to achieve uniform expansion and anti-shaking positioning of the reel's inner hole, significantly improving the stability and safety of the reel transfer process. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is: an anti-sway wire reel transfer tray, which aims to solve the problems of severe shaking, insecure locking, and complex operation during existing wire reel transfer processes, and provides a wire reel transfer tray with a compact structure, simple operation, and anti-sway function. This device combines an eccentric drive linkage mechanism with an elastic expansion joint structure to achieve radial locking of the wire reel's inner hole, improving the stability and safety of the wire reel during transfer and loading / unloading.

[0008] This utility model provides an anti-sway wire spool transfer tray, including a transfer frame, a locking tray, and an expansion joint assembly. The transfer frame has a vertical support on its surface, and several locking trays are detachably fixed to both sides of the vertical support. The expansion joint assembly is fixedly installed on the front surface of the locking tray. The locking tray includes a fixed plate, a drive shaft, and a top block slidably fitted inside the fixed plate. The drive shaft passes through the top block and has a crankshaft pin on its surface, which is fitted inside the top block. One end of the top block is threadedly connected to a rivet head. The expansion joint assembly includes a ring, a deformation plate, and an inner ring. The outer surface of the deformation plate has an abutment, and the rivet head is fitted inside the inner ring. The axial displacement of the top block is achieved through an eccentric crankshaft drive structure, thereby causing the deformation plate to undergo radial elastic deformation, causing the abutment to expand tightly against the inner hole of the wire spool, achieving rapid locking and anti-sway fixation of the wire spool.

[0009] In a preferred embodiment, the present invention is further configured such that: the deformable sheets are evenly distributed along the circumferential direction on the outer periphery of the inner ring and arranged radially, with both ends connected to the inner side of the ring and the outer surface of the deformable sheets, respectively. This structure enables the deformable sheets to uniformly generate elastic bending deformation under axial thrust, thereby forming a symmetrically distributed locking force. Specifically, the technical effect is that the force balance of the coil is achieved through a multi-sheet evenly distributed deformable structure, improving the tension stability and preventing structural loosening caused by coil swaying and uneven force distribution.

[0010] In a preferred embodiment, the present invention is further configured such that: the abutment is arranged on the outer surface of the deformation sheet; when the deformation sheet is bent under force, the abutment expands outward and contacts and locks against the inner wall of the coil; a rubber pad is provided on the surface of the abutment to enhance friction and provide cushioning and protection. Specifically, the rubber pad increases the coefficient of friction between the coil and the expansion joint surface during locking, effectively preventing coil slippage, while also absorbing vibration and improving anti-shaking performance.

[0011] In a preferred embodiment, the present invention is further configured such that: the inner side of the top block is provided with a sleeve hole for through-fitting the drive shaft, and the center of the crankshaft pin is offset relative to the axis of the drive shaft; a throttle is fixedly installed at one end of the drive shaft for manually rotating the drive shaft to drive the top block to generate axial displacement. The specific technical effect is that: mechanical force amplification is achieved through the eccentric mechanism, making the locking and unlocking process smooth and controllable, simple to operate, and enabling rapid loading and unloading without external power.

[0012] In a preferred embodiment, the present invention is further configured such that: the surface of the upright is provided with several flanges for detachable connection to the bottom surface of the fixed tray, thereby enabling quick replacement or adjustment of the installation position of the locking tray. The specific technical effect is that the multi-point flange connection structure improves the flexibility of tray assembly, allows adjustment of the clamping position according to different coil sizes, and enhances the adaptability and maintainability of the device.

[0013] In a preferred embodiment, the present invention is further configured such that: a roller assembly is installed at the bottom of the transfer frame, the roller assembly including directional wheels and omnidirectional wheels, for realizing smooth movement and flexible steering of the transfer frame. The specific technical effect is: the roller structure enables easy movement of the wire reel bracket, reducing the burden of manual handling, while ensuring stable operation of the device and preventing vibration and deviation.

[0014] In a preferred embodiment, the present invention is further configured such that the drive shaft is mounted on a support seat inside the fixed disk via a bearing, thereby maintaining stable support and reducing friction and wear during rotation. Specifically, the bearing support improves the rotational accuracy of the drive mechanism, ensures smooth and reliable expansion joint operation, and extends the service life of the structure.

[0015] In a preferred embodiment, the present invention is further configured such that an integrated arc-shaped reinforcing rib structure is formed between the ring portion and the inner ring, which is used to enhance the structural strength and deformation resistance of the overall structure. Specifically, the arc-shaped reinforcing rib can disperse local stress during the expansion bearing process, preventing fatigue damage to the deformation sheet after long-term use, thereby improving the strength and stability of the entire expansion joint assembly.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the eccentric linkage structure of the drive shaft, crankshaft pin and top block drives the deformation plate in the expansion joint to achieve radial expansion and tightening, so that the lug is firmly attached to the inner wall of the inner hole of the wire spool, thereby effectively preventing the wire spool from shaking, swaying or slipping during the transfer process, and improving the locking stability of the wire spool and the safety of transportation.

[0017] 2. In this utility model, the expansion joint assembly adopts an integrated structure of the ring, inner ring and arc-shaped reinforcing rib, combined with the structure design of metal elastic deformation sheet and rubber gasket, which not only achieves high-strength clamping and buffer protection, but also improves the overall durability and deformation resistance of the device, ensuring a stable and reliable connection of the coil during long-term handling and high-frequency operation.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an anti-sway reel transfer tray.

[0023] Combination Figures 1-5 As shown, the present invention provides an anti-swaying reel transfer tray, which includes a transfer frame 100, a locking tray 200, and an expansion joint assembly 300.

[0024] The surface of the transfer frame 100 is provided with a stand 110, and several locking trays 200 are detachably fixed to both sides of the stand 110. The expansion joint assembly 300 is fixedly installed on the front surface of the locking tray 200. The locking tray 200 includes a fixed plate 210, a drive shaft 220, and a top block 230 that is slidably sleeved inside the fixed plate 210. The drive shaft 220 is arranged through the top block 230, and the surface of the drive shaft 220 is provided with a crankshaft pin 221 that is sleeved inside the top block 230. One end of the top block 230 is threaded with a rivet head 231 for locking and releasing. The expansion joint assembly 300 includes an integrally formed ring 301, an inner ring 303, and several deformation plates 302. The surface of each deformation plate 302 is provided with an abutment 304, and the rivet head 231 is sleeved on the inner side of the inner ring 303 to drive the expansion joint assembly 300 to generate radial expansion deformation. This structural arrangement enables rapid fixing and unlocking of the coil, ensuring the coil remains stable during transportation and transfer.

[0025] In this embodiment, the deformation plates 302 are evenly distributed around the outer periphery of the inner ring 303 along the circumferential direction. Each deformation plate 302 is arranged radially, with its two ends connected to the inner side of the ring portion 301 and the surface of the deformation plate 302, respectively. The deformation plates 302 are made of a metal material with elastic recovery properties, enabling them to undergo controllable deformation under force and return to their original shape after the force is released, thereby achieving repeatable expansion and loosening actions. The evenly distributed deformation plate 302 structure ensures that the inner hole of the coil experiences uniform force during locking, preventing coil wobbling or eccentricity, and specifically improving the positioning accuracy and balance stability of the coil during the expansion process.

[0026] In this embodiment, the abutment 304 is arranged on the outer surface of the deformation plate 302. When the deformation plate 302 is bent under force in the expanded state, the abutment 304 expands outward with the deformation plate 302 and contacts and locks with the inner wall of the inner hole of the coil, realizing radial expansion and tightening fit. A rubber gasket is fixedly installed on the surface of the abutment 304 to increase the contact friction and prevent the coil from sliding during transportation, while also avoiding scratches caused by hard contact between metals. This structure enables the expansion coil assembly 300 to automatically absorb vibration and remain stable during the locking process, thereby achieving the effect of anti-shaking.

[0027] like Figure 4As shown, the inner side of the top block 230 is provided with a sleeve hole that mates with the drive shaft 220. The center of the crankshaft pin 221 is offset relative to the axis of the drive shaft 220, and a throttle is fixedly installed at one end of the drive shaft 220. During operation, the throttle is manually rotated to drive the drive shaft 220 to rotate. Since the crankshaft pin 221 is an eccentric structure, it will push the top block 230 to move axially along the fixed disk 210 when rotating, so that the rivet head 231 presses the inner side of the inner ring 303 to form an axial thrust, thereby causing several deformation plates 302 to produce radial elastic bending, realizing the fastening and locking of the coil. When the drive shaft 220 is rotated in the opposite direction, the top block 230 retracts, and the expansion joint assembly 300 retracts to the initial position under the action of the material elastic restoring force, realizing the rapid release of the coil.

[0028] like Figure 1 and Figure 2 As shown, the surface of the upright 110 is provided with several flanges for detachable connection to the bottom surface of the fixed tray 210. This structure allows the locking tray 200 to be adjusted or disassembled and replaced according to the size of the wire reel or the layout of the workstation, making it suitable for the storage and transfer of wire reels of various specifications, and improving the versatility and expandability of the device.

[0029] In another embodiment, a roller assembly is installed at the bottom of the transfer frame 100. The roller assembly includes directional wheels and omnidirectional wheels to achieve smooth movement and flexible steering of the device. The roller assembly allows for rapid reel positioning and handling within the production workshop without the need for external lifting equipment. The roller support adopts a one-piece welded metal structure, possessing high load-bearing capacity and vibration resistance, ensuring stable movement of the entire device under load.

[0030] like Figure 3 and Figure 5 As shown, the drive shaft 220 is mounted on a support seat inside the fixed disk 210 via bearings, thereby maintaining stable support during rotation, reducing friction and wear, and extending service life. This structure can prevent the top block 230 from shaking and swaying under high-frequency operation, making the transmission smoother and ensuring that the expansion and retraction actions of the expansion joint assembly 300 are precise and reliable.

[0031] Furthermore, an integrated arc-shaped reinforcing rib structure is formed between the ring portion 301 and the inner ring 303, enhancing the overall structure's resistance to deformation and load stability. This arc-shaped reinforcing rib can effectively disperse the axial pressure borne by the inner ring 303 during the expansion process, preventing the disc from deforming or cracking after prolonged use, and improving the durability and structural stability of the expansion disc assembly 300.

[0032] Working principle and usage process of this utility model: The anti-sway wire spool transfer tray of this utility model uses a drive shaft 220 to drive the expansion joint assembly 300 to achieve rapid locking and stable support of the wire spool, thereby preventing the wire spool from shaking and slipping during transportation or loading and unloading. The specific working principle is as follows: When installing the reel onto this device, the operator first inserts the center hole of the reel into the outer side of the expansion joint assembly 300 at the front end of the locking tray 200, so that the inner hole of the reel is coaxially fitted with the outer edge of the ring 301. Then, the operator turns the handle located at one end of the drive shaft 220, manually rotating the drive shaft 220.

[0033] The drive shaft 220 passes through the top block 230 along its axial direction and is fixedly connected to a crankshaft pin 221, the center of which is eccentrically arranged relative to the axis of the drive shaft 220. When the drive shaft 220 rotates, the crankshaft pin 221 moves eccentrically in the sleeve hole inside the top block 230, thereby pushing the top block 230 to reciprocate axially along the inner wall of the fixed disk 210. Since the top block 230 is threadedly connected to the rivet head 231, the forward movement of the top block 230 will drive the rivet head 231 to push forward axially and press against the inner side of the inner ring 303, causing the inner ring 303 to expand radially.

[0034] The radial expansion of the inner ring 303 causes several deformation plates 302 to undergo elastic bending deformation. During deformation, the lugs 304 on the outer surface of each deformation plate 302 expand radially outward, tightly fitting against the inner wall of the coil's inner hole. The rubber pads on the outer surface of the lugs 304 provide anti-slip and cushioning effects during contact, increasing friction and preventing direct metal-to-metal wear. At this time, the coil is firmly clamped under the radial locking force formed by the ring 301 and the lugs 304, achieving stable positioning.

[0035] When the reel needs to be released, the operator rotates the drive shaft 220 in the opposite direction. The top block 230 moves in the opposite direction due to eccentric motion, and the rivet head 231 retracts, releasing the axial clamping force on the inner ring 303. Under the elastic restoring force of the material, the inner ring 303 causes the deformation plate 302 to spring back and retract, disengaging the lug 304 from the inner hole of the reel, thus achieving rapid unloading of the reel.

[0036] During transportation, the spool is simultaneously clamped and secured by multiple locking trays 200 and expansion joint assemblies 300. Each tray can be symmetrically distributed and installed along both sides of the upright frame 110. The upright frame 110 is connected to the transfer frame 100 via a flange structure, ensuring adjustable tray position and secure installation. The roller assembly at the bottom of the transfer frame 100 includes directional wheels and swivel wheels to support the smooth movement of the entire device, keeping the spool vertically stable during movement and preventing swaying or deviation.

[0037] Meanwhile, to ensure the operational stability of the drive mechanism, the drive shaft 220 is mounted on the inner support of the fixed disk 210 via bearings, reducing frictional resistance during rotation, making transmission smoother, and preventing the top block 230 from jamming or eccentrically vibrating. The ring portion 301 and the inner ring 303 in the expansion joint assembly 300 form an integrated arc-shaped reinforcing rib structure, ensuring the entire expansion joint system maintains good rigidity and deformation resistance under high-frequency operation.

[0038] In summary, this invention achieves radial expansion and axial anti-sway support of the reel through the mechanical linkage between the drive shaft 220, crankshaft pin 221, top block 230, and expansion joint assembly 300. This structure requires no external power and can be manually locked and released, offering significant advantages such as compact structure, reliable transmission, excellent anti-sway performance, and strong adaptability. It effectively ensures the stability and safety of the reel during transportation, loading, unloading, and storage.
