Description

Technical Field

[0001] This utility model relates to the technical field of spool storage devices, and more specifically to a three-point force-bearing spool storage device. Background Technology

[0002] In traditional shelving systems, the coils can only be placed on the outside of the shelving or at an angle. This results in large shelving units, making hanging them inconvenient and posing some risks during hanging operations (because the coils are positioned in a straight line, the lifting chain for the coils needs to avoid the coils already placed on the shelving above), and the shelving is impossible to move.

[0003] Due to the aforementioned defects of reel racks on the market, most companies have abandoned using racks and instead placed reels on pallets. Since the reels vary in weight and size, they are difficult to manage on-site. Wiring and cutting require back-and-forth movement between the storage location and the usage location, resulting in low work efficiency and high time costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a three-point force-bearing reel storage device. Through structural innovation and mechanical optimization, this device solves the pain points of traditional reel racks, such as large size, high operational risks, and difficult management. It achieves efficient, safe, and flexible reel hoisting and storage, and has significant practical value and economic benefits.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A three-point force-bearing reel storage device, characterized in that it comprises:

[0007] The shelf has side panels on both sides, and the side panels are provided with hanger connection structures and support seats. The hanger connection structures are used to install and connect with the installation structure at point O, and the support seats are used to support the line reel hanging pipe.

[0008] The hanger has I, O and T points on both sides. I point is a first lifting point for connecting with the hook of the lifting tool. O point is an installation structure for connecting with the hanger connection structure of the side plate to form a rotatable node. T point is a second lifting point for supporting the wire pulley and lifting pipe.

[0009] A reel hanger is installed at point T of the hanger and is used to suspend the reel in mid-air.

[0010] Furthermore, the hanger at point O is installed near the vertical center line of the side panel of the shelf.

[0011] Furthermore, the hanger O point is installed at the vertical center line position of the side panel of the shelf, and the hanger connection structure and support base on the side panel are located on the same vertical line.

[0012] Furthermore, when the IT connection is in a vertical position, the angle between the IO connection and the horizontal line is equal to half the angle between the OT connection 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, 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 hanger connection structure and a support seat.

[0014] Furthermore, the first lifting point, the mounting structure, and the second lifting point at points I, O, and T of the hanger can all be holes, lifting rings, or lifting rod structures.

[0015] Furthermore, the hanger connection structure includes a connection hole, and the mounting structure includes a mounting pin and a mounting hole. The mounting pin can be inserted into the connection hole and the mounting hole to connect the hanger to the side plate.

[0016] 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.

[0017] Furthermore, the shelf includes a base and several uprights, which are inserted into the base for detachable connection.

[0018] Furthermore, the support base includes two rotating seats or two shafts, which are connected to the side plate, and a rotational support space is provided between the two rotating seats or two shafts.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Improved space utilization and ease of operation: The combination of a three-point load-bearing hanger and tiered shelving design enables the suspension and direct placement of reels, effectively reducing shelving volume and optimizing space layout. The tiered design of the suspended and direct placement layers avoids the interference problem of stacked reels in traditional shelving, facilitating quick access to and from the reels and significantly improving operational efficiency.

[0021] 2. Enhanced Stability and Safety: The I, O, and T three-point force-bearing structure of the hanger, combined with mechanical optimization (such as the angular relationship between the IO and OT lines), ensures that the weight of the pulleys is evenly transferred to the center line of the rack side panel through the hanger, greatly reducing the overturning moment (N-overturning) and ensuring the stability of the rack during hoisting. Even when the pulleys move to the highest hoisting level, the device can still maintain stability through the center of gravity balance design, avoiding the risk of tipping over.

[0022] 3. Flexible Adaptability and Scalability: The hanger and rack are detachably installed via latches and connecting holes, allowing for flexible adjustment of the position and number of hanging layers based on the size and quantity of the wire reels. The support base adopts a rotating design, allowing the wire reel hanging tube to rotate freely to adapt to different wire laying requirements. The first lifting point (lifting ring or suspension hole) is compatible with various lifting tools, expanding the applicability of the device.

[0023] 4. Reduced maintenance and management costs: Standardized design (such as unified connection structure for hangers) simplifies the assembly and maintenance process of the racks. Centralized hoisting management with reels avoids the scattered problems of traditional pallet storage, reduces the time spent on-site wiring and cutting, and lowers labor costs.

[0024] 5. Optimized mechanical properties and service life: The stable connection between the rack uprights and the base, the dynamic balance design of the three-point force on the hanger, and the buffer bearing of the support base on the pulley hanger significantly reduce the structural fatigue and wear of the equipment during long-term use, thus extending the equipment's lifespan.

[0025] This utility model solves the pain points of traditional reel racks, such as large size, high operational risk, and difficult management, through structural innovation and mechanical optimization. It achieves efficient, safe, and flexible reel hoisting and storage, and has significant practical value and economic benefits. Attached Figure Description

[0050] Preferably, the second lifting point 203 at the T point of the hanger 2 is a connecting through hole, and the sheave pipe 3 passes through the connecting through hole and extends out of the hanger 2 at both ends;

[0051] Specifically, the sheave pipe 3 is first connected to the sheave, and then installed on the hanger 2, extending out of the hanger 2 through the connecting holes at both ends.

[0052] 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.

[0058] Preferably, the vertical projection of the hanger 2 is triangular, which makes the overall structural dimensions of the hanger 2 more streamlined.

[0059] Technical principle:

[0060] like Figure 3 As shown, the first spool enters from above, which does not address the industry's pain points.

[0061] like Figure 3 As shown, the intersection point Z1 of the outermost edge of the upright 101 of shelf 1 (the entrance end of the sheave hoisting) with the horizon, the intersection point Z2 of the outermost edge of the upright 101 of shelf 1 (the other end of the entrance end of the sheave hoisting) with the horizon, the horizon Z1-Z2, the intersection point C1 of the center line of the upright 101 of shelf 1 (the entrance end of the sheave hoisting) with the horizon, and the intersection point C2 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.

[0062] Width s1 of upright 101 of shelf 1, weight G of spool, length of suspension rope [distance from starting point I on crane hook / hanger 2 to starting point I on crane hook / hanger 2] H1I1, diameter D1 of spool, diameter d2 of spool suspension tube 3; angle β between starting point H1 of crane and starting point I on crane hook / hanger 2 and vertical line H1C1 = ∠IH1C1;

[0063] Hanger 2 has O as the center and IO as the radius R1, hanger 2 has O as the center and OT as the radius R2, and the weight of the reel is G;

[0064] Forces acting on point I: vertical component U1, horizontal component U2;

[0065] Forces acting on point O: vertical component W1, horizontal component W2;

[0066] The component of the force V1 perpendicular to the tangent of the weight G of the spool;

[0067] The component of the tangent force V2 to the weight G of the spool;

[0068] The horizontal component of the tangential force V2 of the weight G of the spool;

[0069] The forces acting on the device are analyzed using three motion position states, while assuming that the weight of the hanger 2 is negligible compared to the weight G of the reel.

[0070] A. Starting position 1: Before the hoisting reel enters shelf 1, such as Figure 4-5 As shown:

[0071] H1 is the position of the hook lifting point, I1 is the center point of the lifting point of the hanger 2, T1 is the center point of the sheave tube 3 of the hanger 2, and O is the force-bearing point where the hanger 2 connects to the shelf 1.

[0072] U1=G (coil reel), U2=0;

[0073] W1=0, W2=0;

[0074] V1=G, V2=0, V22 level=0.

[0075] B. Arbitrary Angle Position: The hanger 2 rotates from its starting position 1, I1O by an angle φ to reach any point position, such as... Figure 6-7 As shown:

[0076] H is the position of the hook lifting point, I is the center point of the lifting point of the hanger 2, T is the center point of the sheave pipe 3 of the hanger 2, L1 is the horizontal distance between point I and point T, and L2 is the horizontal distance between point T and point O.

[0077] U1+W1=G, U1*(L1+L2)=G*L2, from which we can derive U1 and W1;

[0078] U2 = U1 * tan(β);

[0079] W2 = U2;

[0080] V1 = G, V2 = 0, V22 horizontal = 0.

[0081] From Figure 6-7 It can be seen that the center of gravity of the wire reel is between the columns 101C1 and C2 of the shelf 1 and is stable. No matter which horizontal side force the shelf 1 receives, the center of gravity will use C1 or C2 as the fulcrum to generate a "stable torque 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 torque N_overturn around the column 101C2 point. Therefore, as long as the force of U2 is controlled and N_overturn < N_stable, it is one of the key control points of this device. Therefore, the larger N_stable is, the better. Thus, the O force point of the hanger 2 is set near the center line of the shelf 1, which can obtain a better stable torque while meeting the operation reliability. The O point of this device is set on the center line of the side plate 102 of the shelf 1, and the smaller N_overturn is, the better.

[0082] The mechanical model of this device starts from studying the stress state of the wire reel in the uppermost lifting layer. Because the position of the second wire reel from the top is the highest and the N_overturn unstable torque is also the largest, that is, to obtain the smallest N_overturn under the worst working conditions.

[0083] 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 sling of the hook also swings), the position of the force point I of the hanger 2 relative to O is the key control point. When the angle at which IO rotates to the horizontal position = 1 / 2 of the angle at which IO rotates to the end position (that is, when the IT connection line is in the vertical state, the angle between the IO connection line and the horizontal line is equal to 1 / 2 of the angle between the OT connection line and the vertical line), N_overturn is the smallest.

[0084] C. End position 3: The lifting wire reel enters the middle position of the shelf 1, as Figure 8-9 shown:

[0085] The hook suspension point position H3, the suspension point center I3 of the hanger 2, the center T3 of the suspension pipe of the hanger 2;

[0086] When the wire reel suspension pipe 3 approaches but has not fallen into the support seat 104, U1 ≈ 0, W ≈ G, U2 = W2 ≈ 0;

[0087] When the wire reel suspension pipe 3 falls into the suspension pipe support seat 104, U1 = 0, U2 = 0, W1 = 0, W2 = 0;

[0088] V1 = G, V2 = 0, V22 horizontal = 0;

[0089] It can be seen from this that the mechanical model of this device is stable. The spool can be moved from outside the shelf 1 to inside the shelf 1. Due to the force on the intermediate point O, the weight of the spool gradually increases from zero to the weight G of the spool until the spool falls on the "support seat 104" and the weight of the spool is transferred to the support seat 104.

[0090] advantage:

[0091] 1. Improved space utilization and ease of operation: The combined design of the three-point load-bearing hanger 2 and the tiered shelving 1 enables the suspension and direct placement of the reels, effectively reducing the volume of shelving 1 and optimizing the space layout. The tiered design of the suspension and direct placement layers avoids the interference problem of stacked reels in traditional shelving 1, facilitating quick access to and from the reels and significantly improving operational efficiency.

[0092] 2. Enhanced Stability and Safety: The I, O, and T three-point force-bearing structure of the hanger 2, combined with mechanical optimization (such as the angular relationship between the IO and OT lines), ensures that the weight of the pulley is evenly transferred to the center line of the side panel 102 of the rack 1 through the hanger 2, greatly reducing the overturning moment (N overturning) and ensuring the stability of the rack 1 during the hoisting process. Even when the pulley moves to the highest hoisting layer, the device can still maintain stability through the center of gravity balance design, avoiding the risk of tipping over.

[0093] 3. Flexible Adaptability and Scalability: The hanger 2 and shelf 1 are detachably installed via latches and connecting holes, allowing for flexible adjustment of the position and number of hanging layers according to the size and quantity of the wire reels. The support base 104 adopts a rotating design, allowing the wire reel hanging tube 3 to rotate freely to adapt to different wire laying requirements. The first lifting point 202 (lifting ring or suspension hole) is compatible with various lifting tools, expanding the applicability of the device.

[0094] 4. Reduced maintenance and management costs: Standardized design (such as the unified connection structure of hanger 2) simplifies the assembly and maintenance process of rack 1. Centralized hoisting management with reels avoids the scattered problems of traditional pallet storage, reduces the round trip time for on-site wiring and wire cutting, and lowers labor costs.

[0095] 5. Optimized mechanical properties and service life: The stable connection between the upright 101 of the rack and the base, the dynamic balance design of the three-point force of the hanger 2, and the buffer bearing of the support seat 104 on the pulley hanger 3 significantly reduce the structural fatigue and wear of the device during long-term use and extend the service life of the equipment.

[0096] This utility model solves the pain points of traditional wheel racks, such as large size, high operational risk, and difficult management, through structural innovation and mechanical optimization. It achieves efficient, safe, and flexible wheel hoisting and storage, and has significant practical value and economic benefits.
