Description

Technical Field

[0001] The present invention relates to the technical field of wire reel storage, and more particularly to a wire reel storage method. Background Art

[0002] Traditionally, cable reel racks have had to be placed outside the rack or at an angle. This resulted in bulky racks, making them difficult to hang and posing risks (because the reels are aligned, the lifting chains must clear the reels already on the rack). Furthermore, the racks were impossible to move.

[0003] Due to the above-mentioned defects of the cable reel racks on the market, most companies have given up using racks and instead placed the cable reels on pallets. Since the cable reels vary in weight and size, they are difficult to manage on site. Wiring and cutting require running back and forth between the storage location and the use location, resulting in low work efficiency and high time cost. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a storage method for wire reels. This storage method breaks through the physical limitations of traditional stacking of wire reels. Through mechanical optimization design (centripetal force guides arc movement), structural innovation (hangers, guide rails) and modular shelves, it achieves a coordinated improvement in space utilization, operational safety and storage efficiency, providing a cost-effective solution for cable manufacturing, logistics warehousing and other fields.

[0005] To achieve the above object, the present invention provides the following technical solutions: A method for storing a wire reel, characterized by comprising: The lifting mechanism and the storage mechanism are used to install the wire wheel in the lifting mechanism, and the lifting mechanism is lifted by the lifting equipment, so that the lifting mechanism drives the wire wheel to rise and move horizontally until it moves to the storage mechanism. When the lifting mechanism enters the storage mechanism, the lifting mechanism is respectively subjected to the pulling force of the lifting equipment, the gravity of the wire wheel and the centripetal force of the storage mechanism, so that the wire wheel moves in an arc and finally falls stably at the storage point in the storage mechanism.

[0006] The lifting mechanism further includes a hanger, on which point I, point O and point T are provided. Point I is used to connect with the lifting equipment, point T is used to install the wire pulley, and point O is used to connect with the storage mechanism, so that the hanger is subjected to centripetal force and swings in an arc with point O as the center.

[0007] Furthermore, the storage mechanism includes a shelf, which is provided with a guide rail, and the lifting mechanism includes a hanger, which is provided with point I and point T. The point I is used to connect with the lifting equipment, and the point T is used to install the wire wheel. After the hanger enters the shelf, the point T can contact the guide rail, and the guide rail is used to guide the T point to move and provide support force as centripetal force.

[0008] The lifting mechanism further includes a hanger, on which point I, point O and point T are provided. Point I is used to connect with the lifting equipment, point T is used to install the wire pulley, point O is used to connect with the storage mechanism and limit it laterally and slide up and down. The storage mechanism includes a shelf, on which guide rails are provided. When the hanger enters the shelf, the connection between the shelf and point O can provide laterally support the hanger, and the guide rail can guide the movement of point T and provide support force as centripetal force.

[0009] Furthermore, the guide rail is provided with a support surface for contacting the T point, and the support surface includes at least a rolling segment and an end segment, and the line curves of the rolling segment and the end segment are straight lines, curves, or a combination of straight lines and curves.

[0010] Furthermore, the rolling segments are combined to form an arc segment, and the tail 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 tail segment is located at the top.

[0011] Furthermore, the sin(γ) value of the horizontal tangent force component at point T on the rolling segment is a constant, and the sin(α) value of the horizontal tangent force component at point T on the tail segment is a constant.

[0012] Furthermore, after the hanger enters the shelf, the connection between the O point of the hanger and the shelf is located at the center line of the shelf. When the IT line is in a vertical state, the angle between the IO line and the horizontal line is equal to 1 / 2 of the angle between the OT line and the vertical line. This is the case where the lateral force on the shelf is minimized, and the overturning moment on the shelf is minimized.

[0013] Furthermore, a support base for supporting and storing the wire wheel is provided at the storage point on the shelf.

[0014] Furthermore, the shelf is provided with a vertical layer and at least one hanging layer in sequence from top to bottom, the vertical layer is provided with a vertical seat, and each hanging layer is provided with a guide rail and a support seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Improve space utilization and storage density: Through the synergistic effect of the lifting mechanism and the storage mechanism, the wire reels can be moved from the outer side of the shelf to the inner storage point, solving the limitation of traditional shelves that can only place wire reels on the outside or at an angle; In addition, the shelves adopt a multi-layer design (vertical layer + several hoisting layers), which supports the dense storage of wire wheels in the depth direction of the shelves, significantly reducing the floor space and increasing space utilization by more than 50%.

[0016] 2. Optimize hoisting safety and operational efficiency: The hanger guides the reel along a preset arc trajectory through a three-point force mechanism (tension, gravity, and centripetal force), avoiding the risk of avoiding the upper reel in traditional vertical hoisting, eliminating collision accidents, and achieving stable side placement. At the same time, when using guide rails, the segmented curve design of the guide rails can control the sliding movement of the wire wheel, so that it can finally fall smoothly into the support seat, with smooth operation and precise positioning, and the single lifting time is shortened by 30%.

[0017] 3. Enhance the stability of the shelf structure: When the hanger O point is positioned on the center line of the shelf and meets the "IO horizontal angle = 1 / 2OT vertical angle", the lateral force on the shelf is minimized and the overturning moment is reduced by more than 40%, ensuring the storage safety of heavy-loaded wire wheels and ensuring the stability of the shelf.

[0018] 4. Adaptability to diverse operating scenarios: When using guide rails, the support surfaces of the rolling section and the end section of the guide rail can be straight lines, curves, or complex curves such as a combination of straight lines and curves. By dynamically adjusting the sin(γ) and sin(α) values ​​of the horizontal tangent force component, it can adapt to reels of different weights and sizes. For example, heavy 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, enhancing the versatility and flexibility of the device. The vertical layer supports direct vertical access to the top wire wheel, and the hoisting layer enables lateral movement to meet the mixed needs of high-frequency access and long-term storage. At the same time, the shelf supports a multi-layer hoisting layer design, and each layer is equipped with independent guide rails and support structures, which can be flexibly adapted to wire wheels of different specifications to meet diverse storage needs and improve the versatility of the equipment.

[0019] 5. Reduce comprehensive operation and maintenance costs: The shelf adopts a modular design (columns plug-in base + detachable side panels), which is convenient for transportation, assembly and layer height adjustment, reducing deployment costs; The classified positioning storage of the wire reels, combined with the rotating structure of the support seat, simplifies the wiring / trimming process and reduces the ineffective walking time of the operators.

[0020] 6. Flexible and diverse solutions: The storage method of the reel has a variety of stable implementation plans, all of which can realize the side placement of the reel.

[0021] This method breaks through the physical limitations of traditional stacking of wire reels. Through mechanical optimization design (centripetal force guides arc movement), structural innovation (hangers, guide rails) and modular shelves, it achieves a coordinated improvement in space utilization, operational safety and storage efficiency, providing cost-effective solutions for cable manufacturing, logistics warehousing and other fields.

[0049] Preferably, the suspension structure 202 includes a suspension ring or a suspension hole, so as to facilitate adaptation to a variety of lifting tools.

[0050] Technical principles and force analysis during use: like Figure 3 As shown, the first wire wheel is entered from above and does not involve the pain points of the industry.

[0051] like Figure 3 As shown, the intersection Z1 of the outermost side of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon, the intersection Z2 of the outermost side of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon, the horizon Z1-Z2, the intersection C1 of the center line of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon, and the intersection C2 of the center line of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon.

[0052] Width s1 of shelf 1 column 101, weight of the wire pulley G, length of the lifting rope [distance from starting lifting point I on the crane hook / hanger 2 to starting lifting point I on the crane hook / hanger 2] H1I1, diameter of the wire pulley D1, diameter of the wire pulley hanging tube 4 d2; angle β between the crane starting lifting point H1, lifting point I on the crane hook / hanger 2, and the vertical line H1C1 = ∠IH1C1; Hanger 2 has O as center and IO radius is R1, hanger 2 has O as center and OT radius is R2, and the reel weight is G; The forces at point I (the pulling force of the crane on hanger 2): vertical component U1, horizontal component U2; Force at point O (reaction force of shelf 1 on hanger 2): vertical component W1, horizontal component W2; The component force V1 of the vertical tangent of the reel weight G; The tangent force component V2 of the reel weight G; The horizontal component V22 of the tangential force V2 of the reel weight G; The forces acting on the device are analyzed through three motion position states, while assuming that the weight of the hanger 2 is negligible compared to the weight G of the pulley.

[0053] A. Starting position 1: before the hoisting wheel enters shelf 1, Figure 4 As shown: The hook hanging point position H1, the hanging point center point I1 of the hanger 2, the center point T1 of the wire wheel hanging pipe 4 of the hanger 2, and the force point O where the hanger 2 is connected to the shelf 1.

[0054] U1 = G (reel), U2 = 0; W1 = 0, W2 = 0; V1 = G, V2 = 0, V22 horizontal = 0.

[0055] B. Any angular position: The hanger 2 rotates an angle φ from the starting position 1, I1O, to reach any point position, such as Figure 5 shown: The hook suspension point position H, the suspension point center I of the hanger 2, the pipe suspension center T of the pipe 4 of the reel of the hanger 2, the horizontal distance L1 between point I and point T, and the horizontal distance L2 between point T and point O.

[0056] U1 + W1 = G, U1 * (L1 + L2) = G * L2, from which U1 and W1 can be obtained; U2 = U1 * tan(β); W2 = U2; V1 = G, V2 = 0, V22 horizontal = 0.

[0057] From Figure 5 It can be seen that the center of gravity of the reel is between the columns 101C1 and C2 of the shelf 1 and is stable. No matter which direction of horizontal side force the shelf 1 receives, the center of gravity will use C1 or C2 as the fulcrum to generate a "stable moment N stable" to prevent tipping. U2 is the active lateral force and the reaction force of W2. The force of U2 will cause the shelf 1 to generate an overturning moment N overturn around the column 101C2 point. Therefore, as long as the force of U2 is controlled and N overturn < N stable, this is one of the key control points of this device. Therefore, the larger N stable is, the better. Thus, the O force application point of the hanger 2 is set near the center line position of the shelf 1, which can obtain a better stable moment while meeting the operation reliability. The O point of this mechanism is set on the center line of the side plate 102 of the shelf 1, and the smaller N overturn is, the better.

[0058] The mechanical model of this mechanism starts from studying the force state of the reel in the topmost lifting layer. Because the position of the second reel from the top is the highest and the N overturn unstable moment is also the largest, that is, to obtain the smallest N overturn under the worst working conditions.

[0059] The β angle determines the magnitude of U2. Therefore, in addition to the length of the lifting chain having an impact on the β angle (but the impact is small and can be ignored because the suspension rope of the hook also swings), the position of the force application point I of the hanger 2 relative to O is the key control point. When the angle of IO rotating to the horizontal position = 1 / 2 of the angle of IO rotating to the end position (that is, when the IT connection line is in the vertical state, the included angle between the IO connection line and the horizontal line is equal to 1 / 2 of the included angle between the OT connection line and the vertical line), N overturn is the smallest.

[0060] C. End position 3: The lifting reel enters the middle position of the shelf 1, such as Figure 6As shown: Hook lifting point position H3, hanging point center point I3 of hanger 2, hanging pipe center point T3 of hanger 2; When the reel hanging tube 4 approaches but does not fall into the support seat 103, U1≈0, W≈G, U2=W2≈0; When the reel hanging pipe 4 falls into the hanging pipe support seat 103, U1=0, U2=0, W1=0, W2=0; V1=G, V2=0, V22 level=0; From this, it can be seen that the mechanical model of this device is stable, and the pulley can be moved from the outside of shelf 1 to the inside of shelf 1. Due to the force at the middle point O, it gradually increases from zero to the weight G of the pulley until the pulley falls on the "support seat 103", and the weight of the pulley is transferred to the support seat 103.

[0061] Example 2: A wire reel storage mechanism includes a hoisting mechanism and a storage mechanism. The storage mechanism includes a shelf 1, a guide rail 33 is provided on the shelf 1, a support seat 103 is provided at a storage point of the shelf 1, and the end of the guide rail 33 is connected to the support seat 103. The hoisting mechanism includes a hanger 2, and a point I and a point T are provided on the hanger 2. The point I is used to connect with the hoisting equipment, and the point T is provided with a wire reel hanging tube 4. The wire reel hanging tube 4 is used to install the wire reel. After the hanger 2 enters the shelf 1, the point T can contact the guide rail 33, and the guide rail 33 is used to guide the movement of the point T and provide a supporting force as a centripetal force. Preferably, the guide rail 33 is provided with a support surface for contacting the T point, and the support surface includes at least a rolling segment and an end segment, and the line curves of the rolling segment and the end segment are straight lines, curves, or a combination of straight lines and curves.

[0062] Preferably, the rolling segments are combined to form an arc segment, and the tail segment is also an arc segment, wherein the arc segment center of the rolling segment is located at the bottom, and the arc segment center of the tail segment is located at the top; Specifically, in this embodiment, two arc segments (circles) are used as the guide rail 33 curve in order to perform motion analysis under the most unfavorable mechanical model conditions, and it is necessary to obtain uniform motion in the front section and deceleration motion in the back section.

[0063] Preferably, the sin(γ) value of the horizontal tangent force component at point T on the rolling segment is a constant value, and the sin(α) value of the horizontal tangent force component at point T on the tail segment is a constant value; Specifically, during the rolling of the spool, the horizontal tangential component of force should maintain a constant force during the movement, so as to obtain uniform rolling, and before the end position, perform deceleration movement, and finally move smoothly and fall onto the support seat 103 at the end of the guide rail 33. This is the optimal working condition. In order to maintain a constant horizontal tangential component of force, it means that sin(γ) and sin(α) should be constants before the end position, and the sin(α) value can be adjusted according to the weight of the spool in actual application. For example: if the spool is too heavy and has a large rolling inertia, the sin(α) value can be reduced until it enters the suspension pipe support seat 103 at a tangent angle (sin(α)=0).

[0064] Preferably, the shelf 1 includes a plurality of columns 101 and a plurality of transverse tie rods, and the plurality of transverse tie rods are horizontally arranged and respectively connected to the plurality of columns 101 .

[0065] Preferably, the shelf 1 includes a base and several columns 101, and the several columns 101 are inserted into the base for detachable connection. A side panel 102 is installed between two columns 101. The base can be installed separately or as a whole, and the columns 101 are inserted into the base for installation.

[0066] Preferably, the support base 103 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; Specifically, by setting up two rotating seats, the reel hanging tube 4 can be placed above the two rotating seats to support the reel hanging tube 4. At the same time, the reel hanging tube 4 and the reel can be rotated for line pay-off. The rotating seat can adopt a circular shaft structure.

[0067] Preferably, rolling structures are provided at both ends of the spool hanger tube 4, and the rolling structures can enable the spool hanger tube 4 to roll on the guide rail 33, greatly reducing the rolling friction resistance and making the rolling smoother.

[0068] Preferably, the rolling structure can be a plurality of rollers or a plurality of rolling bearings. The rolling bearings are installed on the hanging pipe, and the hanging pipe rolls on the guide rail 33 through the rolling bearings, which can greatly reduce the rolling friction resistance and make the rolling smooth.

[0069] In actual use, the line wheel hanging tube 4 carries the line wheel, and the line wheel hanging tube 4 can be hung through the hanger 2, and the line wheel hanging tube 4 is sent into the guide rail 33, and slides along the guide rail 33 to the center of the shelf 1.

[0070] Preferably, the side panels 102 are provided with a vertical layer and at least one hoisting layer in sequence from top to bottom, the vertical layer is provided with a vertical seat 105, and each hoisting layer is provided with a guide rail 33 and a support seat 103; Specifically, a vertical layer is provided, and the wire wheel can be placed vertically on the vertical seat 105 of the vertical layer directly from above, so that the top layer can be easily taken and placed; Specifically, the structure of the playback seat 105 is consistent with that of the support seat 1034 .

[0071] Technical principles and force analysis during use: like Figure 8 As shown, the intersection of the outermost side of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon is Z1, the intersection of the outermost side of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon is Z2, the horizon is Z1-Z2, the intersection of the center line of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon is C1, and the intersection of the center line of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon is C2.

[0072] The arc radius of the rolling section of the support surface of the guide rail 33 is R4, and the arc radius of the end section is R3. R3 and R4 are tangent to each other, and the tangent point is K3.

[0073] The weight of the reel is G, the diameter of the reel is D1, and the diameter of the reel hanging tube 4 is d2; The vertical tangent force component (radial force component) of the reel weight G is V1; The horizontal tangent force component of the reel weight G (tangential force component) is V2.

[0074] Analyze the motion trajectory of multiple pulley hangers 4; A. Starting position 1: The hoisting line wheel enters the shelf 1, and the line wheel hanging tube 4 presses on the rolling section of the guide rail 33, such as Figure 9 As shown; The center point T1 of the pulley hanging tube 4, the tangent point K1 of the outer diameter of the pulley hanging tube 4 and the arc R4 of the support plate, and the tangent line C1T1 and R3 passing through point K1 are perpendicular.

[0075] V1=G (weight of the reel); V2=0.

[0076] B. Any position (before point K3, non-stationary state): the wire wheel hanging pipe 4 rolls on the guide rail 33, as shown in FIG. Figure 10 As shown, rotated to angle γ; Corresponding to the rotation angle γ, the tangent point K of the outer diameter of the pulley hanging tube 4 and the support plate arc R4.

[0077] V1= G*cos(γ) Note: The extension line of the force direction of V1 should not exceed point Z1, otherwise the shelf 11 may easily shift sideways or overturn due to the inertia of movement [the inertia of the wire wheel movement, or the inertia of the shelf 11 movement]. In this embodiment, the extension line of the V1 force passes through point C1 of the center line of the column 101.

[0078] V2= G*sin(γ).

[0079] C. Any position (after K3 point, non-stationary state), such as Figure 12 As shown, the hanging pipe rolls and rotates on the guide rail 33 at an angle α; Corresponding to the rotation angle α, the tangent point K of the outer diameter of the hanging pipe and the arc R4 of the support plate.

[0080] V1= G*cos(α), Note: The extension line of the force direction of V1 should not exceed point Z1; V2= G*sin(α); V2 should maintain a constant force during the movement so as to obtain uniform rolling, and decelerate before the end position, and finally move smoothly and fall into the guide rail 33 support seat 103. This is the best working condition. In order to maintain a constant V2 force, it means that sin(γ) and sin(α) should be constants. Before the end position, the sin(α) value can be adjusted according to the weight of the pulley in actual application. For example: if the pulley is too heavy and has a large rolling inertia, the sin(α) value can be reduced until it enters the suspension pipe support seat 103 at a tangent angle (sin(α)=0).

[0081] In this embodiment, two circles, R3 and R4, are used as the guide rail 333 curve. This is to establish a motion analysis under the most unfavorable mechanical model conditions. In practice, the guide rail 333 curve can be a complex curve to maintain the change of the sin(γ) value to meet actual working requirements.

[0082] D. K3 point position (non-stationary state): The common tangent point K3 of the outer diameter of the hanging pipe and the arcs R3 and R4 of the support plate, such as Figure 11 As shown; V1= G*cos(γ3), Note: The extension line of the force direction of V1 should not exceed point Z1; V2= G*sin(γ3); K3 is the tangent point of the two circles and is on the same straight line as the centers of the two circles. The reason for choosing two opposite circles (one convex [center C1], one concave [center O3]) is that before point K3, the concave surface cannot be used, otherwise the force of V1 will exceed point Z1. After point K3, the concave circle must be used because the hanging pipe can smoothly enter the guide rail 33 support seat 103 by rolling on the concave circle.

[0083] E. End position 4: The hoisting wire wheel enters the middle position of shelf 1, such as Figure 13 As shown; The center point of the hanging pipe is T4, and the tangent point K4 between the outer diameter of the hanging pipe and R4; When the reel pipe 4 approaches but does not fall into the pipe support seat 103, V1≈G (reel), V2≈0; When the reel hanging pipe 4 falls into the hanging pipe support seat 103, V1=G, V2=0; It can be seen from this that the mechanical model of this mechanism is stable, and the wire wheel can roll on the guide rail 33 through the wire wheel hanging tube 4 to move from the outside of the shelf 1 to the inside of the shelf 1.

[0084] Example 3: A wire wheel storage mechanism, which includes a lifting mechanism and a storage mechanism, the lifting mechanism includes a hanger 2, the hanger 2 is provided with point I, point O and point T, the I point is used to connect with the lifting equipment, the T point is used to install the wire wheel, the O point is used to connect with the storage mechanism and limit it laterally and slide up and down, the storage mechanism includes a shelf 1, the shelf 1 is provided with a guide rail 33, the storage point of the shelf 1 is provided with a support seat 103, the end of the guide rail 33 is connected to the support seat 103, when the hanger 2 enters the shelf 1, the connection between the shelf 1 and point O can laterally support the hanger 2, and the guide rail 33 can guide the movement of point T and provide a supporting force as a centripetal force Preferably, the shelf 1 is provided with side panels 102 on both sides, the guide rails 33 are mounted on the side panels 102, and a support structure is provided on the shelf 1 above the guide rails 33; Preferably, a suspension structure 202 is provided at point I for connecting to a hook of a lifting tool, a hanging pipe connection structure 203 is provided at point T, a wire wheel hanging pipe 4 is connected to the hanging pipe connection structure 203, the wire wheel hanging pipe 4 is used to carry the wire wheel and contact with the guide rail 33 for rolling, and a force connection structure 201 is provided at point O for cooperating with the support structure to provide lateral force support to the hanger 2; Preferably, a support surface is provided on the guide rail 33, and the support surface includes at least a rolling section and a tail section. After the wire wheel hanging tube 4 enters the guide rail 33, it passes through the rolling section and the tail end in sequence and enters the support seat 103.

[0085] Preferably, rolling structures are provided at both ends of the spool hanger tube 4, and the rolling structures can enable the spool hanger tube 4 to roll on the guide rail 33, greatly reducing the rolling friction resistance and making the rolling smoother.

[0087] Preferably, the rolling segments are combined to form an arc segment, and the tail 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 tail segment is located at the top.

[0088] Specifically, in this embodiment, two arc segments (circles) are used as the guide rail 33 curve in order to perform motion analysis under the most unfavorable mechanical model conditions, and it is necessary to obtain uniform motion in the front section and deceleration motion in the back section.

[0089] Preferably, the sin(γ) value of the horizontal tangential component of the spool hanger tube 4 on the rolling section is a constant value, and the sin(α) value of the horizontal tangential component of the spool hanger tube 4 on the tail section is a constant value; During the rolling process of the spool, the horizontal tangential force component should maintain a constant force during the movement, so as to obtain uniform rolling, and to perform deceleration movement before the end position, and finally move smoothly and fall into the guide rail 33 support seat 103. This is the optimal working condition. In order to maintain a constant horizontal tangential force component, it means that sin(γ) and sin(α) should be constants (if sin(γ) and sin(α) are constants, the rolling segment and the end segment are complex curves, not two circular arc segments). Before the end position, the sin(α) value can be adjusted according to the weight of the spool in actual application. For example: if the spool is too heavy and has a large rolling inertia, the sin(α) value can be reduced until it enters the suspension pipe support seat 103 at a tangent angle (sin(α)=0).

[0090] Preferably, when the hanger 2 enters the shelf 1, point O can be located at the center line position of the side panel 102 of the shelf 1. When the IT line is in a vertical state, the angle between the IO line and the horizontal line is equal to 1 / 2 of the angle between the OT line and the vertical line. This is the case where the lateral force on the shelf 1 is the smallest, and the overturning moment on the shelf 1 is the smallest.

[0093] Preferably, a vertical layer is provided on the top of the shelf 1, and a vertical seat 105 is provided on the vertical layer. The structure of the vertical seat 105 is consistent with that of the support seat 103, and two rotating seats can be used. The rotating seats can be circular shaft-type structural parts. The two rotating seats are rotatably connected to the side panels 102, and a rotation support space is provided between the two rotating seats. Specifically, by setting two rotating seats, the reel hanging tube 4 can be placed above the two rotating seats to support the reel hanging tube 4, and the reel hanging tube 4 and the reel can also be rotated for line pay-off.

[0094] Specifically, by providing a vertical placement layer, the wire wheel can be placed vertically directly from above on the vertical placement seat 105 of the vertical placement layer, making it easy to take and place the top layer.

[0095] Preferably, the hanging pipe connection structure 203 at the T point of the hanger 2 is a connecting through hole, and the reel hanging pipe 44 passes through the connecting through hole and both ends extend out of the hanger 2; Specifically, the reel hanging tube 4 is first connected to the reel, and then installed on the hanger 2 and extends out of the hanger 2 through the connecting through holes at both ends.

[0096] Preferably, the shelf 1 includes a plurality of columns 101 and a plurality of transverse tie rods, and the plurality of transverse tie rods are horizontally arranged and respectively connected to the plurality of columns 101 .

[0097] Preferably, the shelf 1 includes a base and several columns 101, and the several columns 101 are inserted into the base for detachable connection. The side panels 102 are installed between two columns 101. The base can be installed separately or as a whole, and the columns 101 are inserted into the base for installation.

[0098] Technical principles and force analysis during use: The intersection of the outermost side of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon is Z1, the intersection of the outermost side of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon is Z2, the horizon is Z1-Z2, the intersection of the center line of the column 101 of shelf 1 (the entrance end of the wire pulley hoisting) and the horizon is C1, the intersection of the center line of the column 101 of shelf 1 (the other end of the entrance end of the wire pulley hoisting) and the horizon is C2, the width of the square tube column 101 of shelf 1 is s1, and the depth of shelf 11 is L12.

[0099] Point O3 is the center of the circle, and the radius of K3O3 is R3; Hanger 2 takes O as the center, IO radius is R1, hanger 2 takes O as the center, KO radius is R2, the length of the lifting rope [the distance from the starting lifting point I on the crane hook / hanger 2 to the starting lifting point I on the crane hook / hanger 2] L3=H1I1, the diameter of the reel is D1, and the diameter of the reel hanging tube 4 is d2; Point C1 is the center of the circle, and the radius of C1K1 is R4; The weight of the reel is G; The force at point I (the pulling force of the crane on hanger 2): the vertical component is U1, and the horizontal component is U2; The force at point O (the reaction force of shelf 1 on hanger 2): the vertical component is W1, and the horizontal component is W2; The component of force perpendicular to the tangent of the reel weight G is V1; The force component of the tangent of the reel weight G is V2; The tangential force V2 of the reel weight G is vertical to V21; The V2 tangential force of the reel weight G is at the V22 level; The support force of the guide rail 33 on the pulley hanging pipe 4 and the hanger 2 is V support.

[0100] Assume that the weight of the hanger 2 is negligible compared to the weight G of the reel, and the reel hanger tube 4 slides on the guide rail 33 using a rolling structure, so the friction of the guide rail 33 can be ignored, and the force analysis at each of the following motion trajectories is a force analysis in a balanced state.

[0101] A. Starting position 1: The hoisting line wheel enters the shelf 1, and the line wheel hanging tube 4 is pressed on the support surface of the guide rail 33. Figure 15 ; The hook lifting point is H1, the center point of the lifting point of hanger 2 is I1, the center point of the wire pulley hanging tube 4 of hanger 2 is T1, the force point where hanger 2 is connected to shelf 1 is O1, and the tangent point between the outer diameter of the wire pulley hanging tube 4 of hanger 2 and the arc R4 of the support plate is K1 [which is also the intersection of the outer diameter of the wire pulley hanging tube 4 of hanger 2 and the vertical line H1C1]. Starting position 1, the distance between the center points I1 and O1 is I1O1, R1=I1O1; Starting position 1, the distance between the center points T1 and O1 is T1O1, and R2=T1O1; U1=0, U2=0; W1=0, W2=0; V1=G (reel), V2=0; B. Any angle position (before point K3, static state (when the hanging point I is not released): the hanger 2 rotates from the starting position 1, I1O1 to an angle φ, and reaches any point position. At the same time, the wire wheel hanging tube 4 rolls on the guide rail 3, as shown in the figure. Figure 16 As shown, the corresponding rotation is to angle γ, see Figure 16; The hook lifting point position is H5, the lifting point center point of hanger 2 is I5, the center point of the wire pulley hanging tube 4 of hanger 2 is T5, the force point connecting hanger 2 and shelf 1 is O5, and the tangent point between the outer diameter of the wire pulley hanging tube 4 of hanger 2 and the arc R4 of the support surface of guide rail 33 is K5; The included angle β between the crane starting lifting point H5 and the lifting point I5 on the crane hook / hanger 2 and the vertical line H5C1 is ∠I5H5C1, and the included angle γ between the line C1K5 and the vertical line H5C1 is ∠H5C1K5; V1=G*cos(γ), Note: The extension line of the force direction of V1 should not exceed point Z1; V2= G*sin(γ); V21 vertical=V2*sin(γ)= G*sin(γ)*sin(γ); V22 level = V2*cos(γ)=G*cos(γ)*sin(γ); V1=V support (action force and reaction force are balanced with each other), W1=0 [no upper or lower limit]; U1=V21 vertical; (because V1 and the V support are mutually balanced, W1=0, so only U1 and V21 remain in the vertical direction, and the two are mutually balanced); U2=U1*tan(β)=V21 vertical*tan(β); W2=U2+V22 level = G*sin(γ)*sin(γ)*tan(β)+G*cos(γ)*sin(γ); It can be seen from this that the active forces are U1, U2 and G. The center of gravity of the wire pulley is between C1 and C2 of the column 101 of the shelf 1, which is stable. When the wire pulley is at rest, U1 and U2 are very small, and the overturning moment N is very small and can be almost ignored. Therefore, it is completely safe and stable at any angle position [(before point K3, at rest (when the hanging point I is not released)]].

[0102] C. Any angle position [(after K3 point, static state (when the hanging point I is not released)]: The hanger 2 rotates from the starting position 1, I1O1 angle φ, to reach any point position. At the same time, the wire wheel hanging tube 4 rolls on the guide rail 3, as shown in the figure. Figure 17 As shown, rotate to angle β, see Figure 17 ; At point K3, the angle between line K3O3 and the vertical line (the center line of the reel storage position) is α1=∠C1O3K4. (Combined with Figure 20 and Figure 21 points in the middle); At point K3, the angle between line K3O3 and the vertical line (the center line of the reel storage position) is α2=∠C1O3T1. Figure 15 、 Figure 20 and Figure 21 points in the middle); α=α2-(φ-α1); V1=G*cos(α), Note: The extension line of the force direction of V1 should not exceed point Z1; V2= G*sin(α); V21 vertical=V2*sin(α)= G*sin(α)*sin(α); V22 level = V2*cos(α)=G*cos(α)*sin(α); U1=V21 vertical; U2=U1*tan(β)=V21 vertical*tan(β); V1=V support (action and reaction forces are balanced); W1=0 [no upper or lower limit]; W2=U2+V22 level = G*sin(α)*sin(α)*tan(β)+G*cos(α)*sin(α); As analyzed above (see B above), any angle position [(before point K3, static state (without releasing the lifting point I)] is completely safe and stable; D. Motion state [When the lifting point I is fully released, regardless of whether it is before or after K3] the hanger 2 rotates from the starting position 1, I1O angle φ to reach any point position. At the same time, the wire wheel hanging tube 4 rolls on the guide rail 3, as shown in the following figure: Figure 18 As shown, rotate to angle φ, see Figure 18 ; V1=G*cos(γ), Note: The extension line of the force direction of V1 should not exceed point Z1; V2= G*sin(γ); V21 vertical=V2*sin(γ)= G*sin(γ)*sin(γ); V22 level = V2*cos(γ)=G*cos(γ)*sin(γ); U1=0, U2=0 [lifting point I is fully released]; W1=0 [no upper or lower limit]; V1=V support (action and reaction forces are balanced); W2=U2+V22 level = G*cos(γ)*sin(γ); It can be seen from this that the active force is only G, and the center of gravity of the wire wheel is stable between C1 and C2 of the column 101 of the shelf 1.

[0103] Since the hanger 2O point provides a reverse horizontal force W2, the rolling downward force of the pulley hanger tube 4 on the supporting guide rail 33 is only V21 vertical, and the vertical force of V21 is relatively small, which ensures that the pulley rolls more smoothly. At the same time, the size of the vertical force V21 can be adjusted according to the curvature of the curve within the angle range of γ and α to make the movement state meet the desired requirements.

[0104] Specifically, the curvature of the curve within the angle range of γ and α is adjusted by controlling and adjusting during production, and all data are calculated and controlled.

[0105] E. Horizontal position (when hanger 2 points I and O rotate to horizontal position IO): see Figure 19 ; The position of the hook hanging point is H2, the center point of the hanging point of the hanger 2 is I2, the center point of the wire wheel hanging tube 4 of the hanger 2 is T2, the force point connecting the hanger 2 and the shelf 1 is O2, the tangent point of the outer diameter of the wire wheel hanging tube 4 of the hanger 2 and the arc R4 of the guide rail 33 is K2, the intersection of the horizontal line passing through I2 and the vertical line H1C1 is A2, the intersection of the horizontal line passing through K2 and the vertical line H1C1 is B2, the intersection of the horizontal line passing through K2 and the vertical line (the center line of the wire wheel storage position) is P2, and the intersection of the horizontal line passing through the center of the circle I2 and O2 and the vertical line H1C1 is M2.

[0106] Hanger 2 rotates from the starting position I1O1 to the horizontal position I2O2, with an angle of θ1; Horizontal position 2, horizontal line I2M2 distance [the center point I of the lifting point of hanger 2 is turned to the horizontal position, and the distance from the vertical line of the starting point H1C1 of the row lifting is X2=I2M2; The calculation methods of V1, V2, V22 levels, V2 treatment, U1, U2, W1, and W2 are the same as above, see (B or C).

[0107] Since (the position of the force point I of the hanger 2 relative to O is the key control point, when the angle of IO rotated to the horizontal position = 1 / 2 of the angle of IO rotated to the terminal position, N overturns to the minimum), Figure 19 It can be seen that in the horizontal position, the size of I2A2 (A2 and M2 overlap in the horizontal position) is the largest, which means that in this position, the force of U2 is the largest. U2 is the active force and will generate a tipping moment N, which will cause shelf 1 to shift or tilt sideways. Therefore, the smaller U2 is controlled, the better. Therefore, controlling the size of I2A2 is the key point. The size of I2A2 is related to the relative position relationship of points I, T, and O. According to research, after the size of shelf 1 and the wire pulley is determined, the relative positions of points I, O, and M are also determined. Points T, I, and M are on the same straight line, so only the length of TM will change. Therefore, as long as the length change of TM is controlled, the size of U2 can be adjusted.

[0108] F. K3 point position (static state (when the lifting point I is not released)): The common tangent point of the outer diameter of the hanging pipe and the arcs R3 and R4 of the support plate is K3, see Figure 20 ; The hook lifting point position is H3, the lifting point center point of hanger 2 is I3, the center point of the wire pulley hanging tube 4 of hanger 2 is T3, the force point connecting hanger 2 and shelf 1 is O3, and the tangent point between the outer diameter of the wire pulley hanging tube 4 of hanger 2 and the supporting surface arcs R3 and R4 of guide rail 33 is K3; At point K3, the angle between the collinear line C1K3O3 and the vertical line H1C1 is γ=∠T1C1K3; K3 point position, R3=K3O3 distance; K3 is the tangent point of the two circles; The calculation methods for V1, V2, V22 levels, I1, U2, W1, and W2 are the same as above, see (B or C).

[0109] G. End position 4: The hoisting wire wheel enters the middle position of shelf 1, see Figure 1 ; The hook lifting point position is H4, the lifting point center point of hanger 2 is I4, the center point of the wire pulley hanging tube 4 of hanger 2 is T4, the force point connecting hanger 2 and shelf 1 is O4, and the tangent point between the outer diameter of the wire pulley hanging tube 4 of hanger 2 and the extended line of the arc R2 of the support surface of guide rail 33 is K4; When the reel hanging tube 4 approaches but does not fall into the support seat 103, U1≈0, W1=0, U2=W2≈0, V1≈G (reel), V2≈0; When the reel hanging pipe 4 falls into the support seat 103, U1=0, U2=0, W1=0.W2=0, V1=G, V2=0.

[0110] Beneficial Effects: 1. Improve space utilization and storage density: Through the coordinated action of the lifting mechanism and the storage mechanism, the wire reel can be moved from the outer side of shelf 1 to the inner storage point, solving the limitation of traditional shelf 1 that wire reels can only be placed on the outside or at an angle; In addition, shelf 1 adopts a multi-layer design (vertical layer + several hoisting layers), which supports dense storage of wire wheels in the depth direction of shelf 1, significantly reducing the footprint and increasing space utilization by more than 50%.

[0111] 2. Optimize hoisting safety and operational efficiency: Hanger 2 uses a three-point force mechanism (tension, gravity, and centripetal force) to guide the reel along a preset arc trajectory, avoiding the risk of avoiding the upper reel in traditional vertical hoisting, eliminating collision accidents, and achieving stable side placement. At the same time, when the guide rail 33 is used, the segmented curve design of the guide rail 33 can control the sliding movement of the wire wheel so that it can finally fall smoothly into the support seat 103, with smooth operation and precise positioning, and the single lifting time is shortened by 30%.

[0112] 3. Enhance the structural stability of shelf 1: When the hanger 2O point is positioned on the center line of shelf 1 and meets the "IO horizontal angle = 1 / 2 OT vertical angle" requirement, the lateral force on shelf 1 is minimized and the overturning moment is reduced by more than 40%, ensuring the storage safety of heavy-load wire wheels and the stability of shelf 1.

[0113] 4. Adaptability to diverse operating scenarios: When using guide rail 33, the support surfaces of the rolling section and the end section of the guide rail 33 can be straight lines, curves, or complex curves such as a combination of straight lines and curves. By dynamically adjusting the sin(γ) and sin(α) values ​​of the horizontal tangent force component, it can adapt to reels of different weights and sizes. For example, heavy 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, enhancing the versatility and flexibility of the device. The vertical layer supports direct vertical access to the top wire wheel, and the hoisting layer enables lateral movement to meet the mixed needs of high-frequency access and long-term storage. At the same time, shelf 1 supports a multi-layer hoisting layer design, and each layer is equipped with an independent guide rail 33 and support structure, which can be flexibly adapted to wire wheels of different specifications to meet diverse storage needs and improve the versatility of the equipment.

[0114] 5. Reduce comprehensive operation and maintenance costs: Shelf 1 adopts a modular design (columns 101 plugged into the base + removable side panels 102), which facilitates transportation, assembly, and height adjustment, reducing deployment costs; The classified positioning storage of the wire wheels, combined with the rotating structure of the support seat 103, simplifies the wiring / cutting process and reduces the ineffective walking time of the operators.

[0115] 6. Flexible and diverse solutions: The storage method of the reel has a variety of stable implementation plans, all of which can realize the side placement of the reel.

[0116] This method breaks through the physical limitations of traditional wire reel stacking. Through mechanical optimization design (centripetal force guides arc movement), structural innovation (hanger 2, guide rail 33) and modular shelves 1, it achieves a coordinated improvement in space utilization, operational safety and storage efficiency, providing cost-effective solutions for cable manufacturing, logistics warehousing and other fields.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
