Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spool storage devices, and more specifically to a guide rail rolling-in spool storage device. Background Technology
[0002] Traditional reel racks commonly suffer from the following technical drawbacks in industrial applications: ① Low space utilization: Reels can typically only be fixed to the outside of the rack or placed at an angle, resulting in bulky racks that are difficult to adapt to compact storage environments. Furthermore, excessive operating space is required when stacking multiple layers, leading to low storage efficiency. ② High lifting risk: During lifting, the lifting chain must avoid the upper reels, making it prone to tipping or slippage due to operational errors, posing significant safety hazards. Additionally, the immobility of traditional racks limits the flexibility of reel movement. ③ Limited applicability: Existing racks largely rely on forklifts or manual handling, making them unsuitable for heavy reels. Repeated movement of the racks is necessary for retrieving and storing reels, resulting in low operational efficiency and increased time costs. ④ Insufficient mechanical stability: Uneven weight distribution when reels are stored makes the rack susceptible to lateral forces, generating overturning moments, especially in high-rise storage scenarios where stability is difficult to guarantee. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a guide rail rolling-in type spool storage device. This guide rail rolling-in type spool storage device, through guide rail rolling-in design, combined with mechanical analysis and structural optimization, achieves smooth rolling of the spools, precise positioning, and improved mechanical stability of the shelf.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A guide rail-mounted roller reel storage device includes:
[0006] The shelf has side panels on both sides, guide rails are mounted on the side panels, and support seats are provided on the side panels at the ends of the guide rails;
[0007] A wire reel lifting tube is used to lift the wire reel, and the wire reel lifting tube can enter the guide rail for rolling.
[0008] The guide rail has a support surface, which includes at least one rolling section and one end section. After the sheave enters the guide rail, it passes through the rolling section and the end section in sequence and enters the support seat.
[0009] Furthermore, the two ends of the sheave tube are provided with rolling structures, which enable the sheave tube to roll on the guide rail, greatly reducing rolling friction resistance and making the rolling smoother.
[0010] Furthermore, the rolling section and the end section of the guide rail support surface are made of straight lines, curves, or a combination of straight lines and curves.
[0011] Furthermore, the rolling segments are combined to form an arc segment, and the end segment is also an arc segment, wherein the center of the arc segment of the rolling segment is located at the bottom, and the center of the arc segment of the end segment is located at the top.
[0012] Furthermore, the sin(γ) value of the horizontal tangential component of the sheave guide on the arc segment of the rolling section is a constant, and the sin(α) value of the horizontal tangential component of the sheave guide on the arc segment of the end section is a constant.
[0013] Furthermore, the shelving unit includes several uprights and several horizontal tie rods, with the horizontal tie rods arranged horizontally and connected to the uprights respectively.
[0014] Furthermore, the shelf includes a base and several uprights, which are inserted into the base for detachable connection.
[0015] Furthermore, the side panel is provided with a straight placement layer and at least one hoisting layer from top to bottom. The straight placement layer is provided with a straight placement seat, and each hoisting layer is provided with a guide rail and a support seat.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model, through a guide rail rolling design, combined with mechanical analysis and structural optimization, achieves smooth rolling of the rollers, precise positioning, and improved mechanical stability of the shelving, as detailed below:
[0018] 1. Segmented control of guide rails:
[0019] Rolling section: A circular arc guide rail (convex circle with the center at the bottom) is used. By matching the curvature of the guide rail with the component of gravity (V2), the thread sheave tube rolls at a uniform speed along the tangential direction under the action of gravity, ensuring that the movement process is smooth and controllable.
[0020] The final section uses a reverse circular arc guide rail (concave circle with the center at the top). By changing the curvature, the rolling resistance is increased, which slows down the sheave tube as it approaches the support seat, ultimately achieving precise positioning and avoiding displacement or overturning caused by impact.
[0021] 2. Space utilization is significantly optimized:
[0022] By setting up multiple hanging and upright layers, combined with a guide rail roll-in structure, the system allows for dense vertical storage of wire reels, while the vertical placement of the upright layers further reduces lateral space occupation. Multiple layers can be stacked without requiring excessive operating space, effectively adapting to compact storage environments and improving storage density and space utilization.
[0023] 3. Widely compatible with different reel specifications:
[0024] The rolling section and the end section of the guide rail adopt an adjustable circular arc curve design. By dynamically adjusting the sin(γ) and sin(α) values of the horizontal tangential component, it can adapt to reels of different weights and sizes. For example, heavy-duty reels can achieve deceleration optimization by reducing the sin(α) value of the end section, ensuring that all types of reels can be positioned smoothly, thus enhancing the versatility and flexibility of the device.
[0025] 4. Automation and efficiency improvement:
[0026] The sheave-type lifting tube slides autonomously on the guide rail via a rolling structure, reducing the frequency of forklift or manual handling. During storage and retrieval, only initial lifting or forklift support is required; subsequent positioning is automatically completed by gravity and guide rail guidance, significantly reducing manual operation intensity, shortening the work cycle, and improving the efficiency of sheave rotation.
[0027] 5. Enhanced safety features across the board:
[0028] The mechanical balance design ensures that the center of gravity of the sheave and lifting pipe remains within the anti-tipping moment range of the rack uprights, while the deceleration design at the end of the guide rail effectively prevents impact-induced deviation. Furthermore, the separate layout of the lifting layer and the direct placement layer reduces the risk of interference between the lifting chain and the upper sheave, structurally eliminating the hazards of tilting and slippage, thus ensuring operational safety.

[0040] A guide rail 3-type roller reel storage device includes:
[0041] Shelf 1, with side panels 102 on both sides, guide rails 3 installed on the side panels 102, and support bases 4 provided on the side panels 102 at the ends of the guide rails 3;
[0042] The reel lifting pipe 2 is used to lift the reel and can enter the guide rail 3 to roll.
[0043] The guide rail 3 has a support surface, which includes at least one rolling section and one end section. After the sheave tube 2 enters the guide rail 3, it passes through the rolling section and the end section in sequence and enters the support seat 4.
[0044] Preferably, the two ends of the sheave tube 2 are provided with rolling structures, which enable the sheave tube 2 to roll on the guide rail 3, greatly reducing rolling friction resistance and making the rolling smoother.
[0045] Preferably, the rolling section and the end section of the support surface of the guide rail 3 are straight lines, curves, or a combination of straight lines and curves.
[0046] Preferably, the rolling segments are combined to form an arc segment, and the end segment is also an arc segment, wherein the center of the arc segment of the rolling segment is located at the bottom, and the center of the arc segment of the end segment is located at the top;
[0047] Specifically, in this embodiment, two circular arc segments (circles) are used as the guide curve 3. This is to perform motion analysis under the most unfavorable mechanical model conditions, requiring the acquisition of uniform motion in the initial segment and decelerated motion in the subsequent segment.
[0048] Preferably, the sin(γ) value of the horizontal tangential component of the sheave guide on the arc segment of the rolling section is a constant, and the sin(α) value of the horizontal tangential component of the sheave guide on the arc segment of the end section is a constant.
[0049] The guide rail 3 curve is a complex curve, which can be adapted to different actual working needs by changing the sin (angle) value;
[0050] Specifically, the horizontal tangential component should remain constant during the motion to achieve uniform rolling and deceleration before the termination position, ultimately moving smoothly and falling into the guide rail 3 support 4. This is the optimal working condition. To maintain a constant horizontal tangential component, sin(γ) and sin(α) should be constant values. Before the termination position, the value of sin(α) can be adjusted according to the weight of the reel in actual application. For example, for a heavy reel with high rolling inertia, the value of sin(α) can be reduced until it enters the hanging pipe support 4 at a tangential angle (sin(α)=0).
[0051] Preferably, the shelf 1 includes a plurality of uprights 101 and a plurality of horizontal tie rods, wherein the plurality of horizontal tie rods are arranged horizontally and are respectively connected to the plurality of uprights 101.
[0052] Preferably, the shelf 1 includes a base and several uprights 101, the uprights 101 are inserted into the base for detachable connection, the side plate 102 is installed between two uprights 101, the base can be installed separately or as a whole, and the uprights 101 are inserted into the base for installation.
[0053] Preferably, the support base 4 includes two rotating bases, which are rotatably connected to the side plate 102, and a rotating support space is provided between the two rotating bases;
[0054] Specifically, by setting two rotating seats, the wire sheave hanging pipe 2 can be placed above the two rotating seats to support the wire sheave hanging pipe 2, and at the same time, the wire sheave hanging pipe 2 and the wire sheave can rotate for wire feeding. The rotating seats can adopt a circular shaft structure.
[0055] Preferably, the rolling structure can be a number of rollers or a number of rolling bearings. By installing rolling bearings on the hanging pipe and allowing the hanging pipe to roll on the guide rail 3 through the rolling bearings, the rolling friction resistance can be greatly reduced, making the rolling smooth.
[0056] In actual use, the spool hanger 2 carries the spool. The spool hanger 2 can be suspended by the hanger 5 or the spool can be supported by a forklift. The spool hanger 2 is sent into the track and slides into the center of the rack 1. When it is taken out, the spool hanger 2 is already on the hanger support 4. Only the forklift can be used to lift the spool and move it out of the rack 1.
[0057] Preferably, the side plate 102 is provided with a straight placement layer and at least one hoisting layer from top to bottom. The straight placement layer is provided with a straight placement seat, and each hoisting layer is provided with a guide rail 3 and a support seat 4.
[0058] Specifically, by setting up a vertical placement layer, the reel can be placed directly and vertically on the vertical placement layer from above, making it convenient to take out and put in the top layer;
[0059] Specifically, the structure of the upright seat is the same as that of the support seat 4.
[0060] Technical principle analysis:
[0061] The intersection of the outermost point of the upright 101 of shelf 1 (the entrance end of the sheave hoisting) with the horizon is Z1. The intersection of the outermost point of the upright 101 of shelf 1 (the other end of the entrance end of the sheave hoisting) with the horizon is Z2. The horizon is Z1-Z2. The intersection of the center line of the upright 101 of shelf 1 (the entrance end of the sheave hoisting) with the horizon is C1. The intersection of the center line of the upright 101 of shelf 1 (the other end of the entrance end of the sheave hoisting) with the horizon is C2.
[0062] The radius of the arc of the rolling section of the support surface of guide rail 3 is R4, and the radius of the arc of the end section is R3. R3 and R4 are tangent to each other at point K3.
[0063] Weight of the reel G, diameter of the reel D1, diameter of the reel suspension tube 2 d2;
[0064] The component of the force perpendicular to the tangent (radial component) of the weight G of the spool, V1;
[0065] The component of the horizontal tangent force (tangential component) of the weight of the spool G is V2.
[0066] The motion trajectory of the multiple sheaves and pipes 2 is analyzed.
[0067] A. Starting position 1: The lifting spool enters the rack 1, and the spool lifting tube 2 presses against the rolling section of the track, as shown. Figure 3 As shown;
[0068] The center point T1 of the sheave tube 2, the tangent point K1 between the outer diameter of the sheave tube 2 and the arc R4 of the support plate, and C1T1 are perpendicular to the tangent line of R3 passing through point K1.
[0069] V1 = G (weight of the spool);
[0070] V2=0.
[0071] B. At any position (before point K3, in a non-stationary state): the cable duct rolls on the track, such as... Figure 4 As shown, rotate to angle γ;
[0072] The corresponding rotation angle γ corresponds to the tangent point K between the outer diameter of the hanging pipe and the arc R4 of the support plate.
[0073] V1 = G*cos(γ) Note: The extension line of the force direction of V1 should not exceed point Z1. Otherwise, the shelf 1 is prone to lateral displacement or overturning due to motion inertia [inertia in the movement of the wheel or inertia in the movement of the shelf 1]. In this embodiment, the extension line of the force V1 passes through point C1, the center line of the column 101.
[0074] V2 = G*sin(γ).
[0075] C. Any position (after point K3, in a non-stationary state), such as Figure 6 As shown, the pipe rotates by an angle α on the track;
[0076] The corresponding rotation angle α corresponds to the tangent point K between the outer diameter of the hanging pipe and the arc R4 of the support plate.
[0077] V1 = G*cos(α), Note: The extension line of the force direction of V1 should not exceed point Z1;
[0078] V2 = G*sin(α);
[0079] V2 should maintain a constant force during the movement to achieve uniform rolling and decelerate before reaching the final position, eventually moving smoothly and falling into the guide rail 3 support 4. This is the optimal working condition. To maintain a constant V2 force, sin(γ) and sin(α) should be constant values. Before reaching the final position, the value of sin(α) can be adjusted according to the weight of the reel in the actual application. For example, if the reel is too heavy, the rolling inertia is large, so the value of sin(α) can be reduced until it enters the hanging pipe support 4 at a tangential angle (sin(α)=0).
[0080] The enumerated examples in this invention use two circles, R3 and R4, as the guide rail curve 3 to perform motion analysis under the most unfavorable mechanical model conditions. In reality, the guide rail curve 3 can be a complex curve to maintain the variation of the sin(γ) value to adapt to actual working needs.
[0081] D. Location of point K3 (non-static state): K3 is the common tangent point between the outer diameter of the hanging pipe and the arcs R3 and R4 of the support plate, such as... Figure 5 As shown;
[0082] V1 = G*cos(γ3), Note: The extension line of the force direction of V1 should not exceed point Z1;
[0083] V2 = G*sin(γ3);
[0084] K3 is the point of tangency between the two circles and is on the same straight line as the center of the two circles. The reason for choosing two opposite circles (one convex [center C1], one concave [center O3]) is that before point K3, a concave surface cannot be used, otherwise the force of V1 will exceed point Z1. After point K3, a concave circle must be used because the hanging tube can smoothly enter the guide rail 3 support seat 4 when it rolls on the concave circle.
[0085] E. Termination Position 4: The lifting spool enters the middle position of shelf 1, such as... Figure 7 As shown;
[0086] The center point of the lifting pipe is T4, and the point of tangency between the outer diameter of the lifting pipe and R4 is K4;
[0087] When the reel and the hanging pipe 2 approach but before it falls into the hanging pipe support 4, V1≈G (reel), V2≈0;
[0088] When the sheave pipe 2 falls into the pipe support 4, V1=G, V2=0;
[0089] This shows that the mechanical model of the device is stable, and the reel can roll on the guide rail 3 through the reel hanging tube 2 to move from the outside of the shelf 1 to the inside of the shelf 1.
[0090] advantage:
[0091] The technical principle of this utility model lies in the use of a roller-in design of the guide rail 3, combined with mechanical analysis and structural optimization, to achieve smooth rolling and precise positioning of the rollers and improve the mechanical stability of the shelf 1, as detailed below:
[0092] 1. Guide rail 3-segment control:
[0093] Rolling section: A circular arc guide rail 3 (convex circle with the center at the bottom) is used. By matching the curvature of the guide rail 3 with the component of gravity (V2), the sheave tube 2 rolls at a uniform speed along the tangential direction under the action of gravity, ensuring that the movement process is stable and controllable.
[0094] The final section uses a reverse circular arc guide rail 3 (concave circle with the center at the top) to increase rolling resistance through curvature changes, so that the sheave tube 2 decelerates when it approaches the support seat 4, and finally achieves precise positioning, avoiding displacement or overturning caused by impact.
[0095] 2. Space utilization is significantly optimized:
[0096] By setting up multiple hanging and upright layers, combined with a 3-rail roll-in structure, the system allows for dense vertical storage of wire reels, while the vertical placement of the upright layers further reduces lateral space occupation. Multiple layers can be stacked without requiring excessive operating space, effectively adapting to compact storage environments and improving storage density and space utilization.
[0097] 3. Widely compatible with different reel specifications:
[0098] The rolling section and the end section of guide rail 3 adopt an adjustable circular arc curve design. By dynamically adjusting the sin(γ) and sin(α) values of the horizontal tangential component, it can adapt to reels of different weights and sizes. For example, heavy-duty reels can achieve deceleration optimization by reducing the sin(α) value of the end section, ensuring that all types of reels can be positioned smoothly, thus enhancing the versatility and flexibility of the device.
[0099] 4. Automation and efficiency improvement:
[0100] The sheave 2 slides autonomously on the guide rail 3 via a rolling structure, reducing the frequency of forklift or manual handling. During storage and retrieval, only initial lifting or forklift support is required; subsequent positioning is automatically completed by gravity and guidance from the guide rail 3, significantly reducing manual operation intensity, shortening the work cycle, and improving the efficiency of sheave rotation.
[0101] 5. Enhanced safety features across the board:
[0102] The mechanical balance design ensures that the center of gravity of the sheave 2 remains within the anti-tipping moment range of the upright 101 of the rack, while the deceleration design at the end of the guide rail 3 effectively prevents impact deviation. In addition, the separate layout of the lifting layer and the direct placement layer reduces the risk of interference between the lifting chain and the upper sheave, structurally eliminating the hidden dangers of tilting and slippage, and ensuring operational safety.
[0103] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
