Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stereoscopic warehouse, in particular to a steel coil automatic stereoscopic warehouse. BACKGROUND

[0002] Steel coil is a kind of extremely important semi-finished product form in modern steel industry, which is a high-efficiency profile product formed by continuously rolling flat steel through advanced hot rolling or cold rolling process. However, the mainstream storage mode of this product form of steel coil in warehouse management practice is no more than two types: one is single-layer plane storage, which has the advantages of simple management, high safety of storage and retrieval operation, and almost no additional storage load on the steel coil itself, but its most prominent disadvantage is the extremely low utilization of warehouse space; the other is multi-layer stacking storage, which greatly improves the space utilization of the warehouse in theory and practice by stacking multiple steel coils in the vertical direction. However, as a heavy industrial product, the self-weight of steel coil is very large, and when stacked in multiple layers, the lower steel coil needs to bear a large static load from the upper steel coil. Long-term and uneven concentrated stress can easily cause irreversible plastic deformation of the barrel of the steel coil. In addition, during stacking, storage and daily vibration, the hard metal surfaces of the steel coils will inevitably come into direct contact and relative displacement, resulting in appearance defects such as scratches and scratches on the precise rolling surface or corrosion-resistant coating of the steel coils.

[0003] Chinese patent application CN120348620A discloses a super-long and super-heavy steel coil stereoscopic warehouse system and a use method. In this device, the hydraulic lifting mother-daughter car adopts a unique bottom lifting method to transfer the steel coil, without relying on the bearing frame and transmission components around the steel coil. Compared with the traditional chain hoisting or fork lifting scheme, this design greatly simplifies the mechanical structure, reduces the weight of the equipment, realizes a more compact overall layout, effectively saves the occupied space, which not only reduces the power consumption and operating cost, but also makes the maintenance more simple. The carrying capacity and safety of the equipment are significantly better than those of the traditional method, and the high-position operation characteristics are conducive to building a dense stereoscopic shelf, which greatly improves the space utilization.

[0004] However, in the existing steel coil stereoscopic warehouse solution, there is a core contradiction: how to ensure the stability of the steel coil during the movement while considering the passability of the equipment in the narrow storage space. The traditional support structure relies on the line contact or narrow arc surface contact formed by the support table and the outer wall of the steel coil. This way provides limited support area and cannot effectively resist the overturning moment generated by inertia during the start, braking or running of the steel coil. Especially for horizontally placed steel coils with high center of gravity, there are significant safety hazards. To solve this problem, some improved solutions try to add side plates to expand the support surface. However, the distance of the side plate support is often still less than the distance of the saddle, which reduces the support effect of the side plate. Moreover, the side plate occupies horizontal space, which prevents the self-propelled sub-car from smoothly entering and exiting the storage cavity inside the rack, or interferes with the inherent saddle in the warehouse, severely restricting the space utilization and operational flexibility of the stereoscopic warehouse.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the referred component or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0026] The following is based on the description of the present application Figure 1 Figure 13 The steel coil automatic stereoscopic warehouse provided by the embodiments of the present application is described.

[0027] Please refer to Figure 1 Figure 13 The embodiments of the present application provide a technical solution: a steel coil automatic stereoscopic warehouse, comprising a hydraulic lifting mother-daughter car 1, a self-propelled car 3 and a stereoscopic warehouse 5, at least two layers of storage cavities 5005 are provided in the stereoscopic warehouse 5, wherein the gap between the stereoscopic warehouses 5 is used for the movement of the hydraulic lifting mother-daughter car 1.

[0028] The steel coil automatic stereoscopic warehouse provided by the present application further comprises a saddle 5001 and a support assembly, the saddle 5001 is symmetrically arranged on both sides of the storage cavity 5005 in the stereoscopic warehouse 5, and is used for supporting the storage of the steel coil 4 and maintaining the stability of the steel coil 4 after storage, and the support assembly is arranged on the self-propelled car 3 and is used for supporting the steel coil 4 during movement, thereby improving the stability of the steel coil 4 during movement.

[0029] ​​The support assembly provided by the embodiment comprises the U-shaped frames 9, the side plates 8 and the connecting rods, wherein the U-shaped frames 9 are provided in two groups, the two ends of the two groups of U-shaped frames 9 are upward and form the support tables 7, the support of the steel coil 4 during movement is realized through cooperation of the support tables 7, the side plates 8 are provided in two groups, the two groups of side plates 8 are symmetrically rotatably installed between the two groups of U-shaped frames 9, the side plates 8 are movable to increase the contact area of the steel coil 4 and the support surface, the connecting rods are arranged on the self-walking sub-car 3, the connecting rods are movable to drive the side plates 8 and the U-shaped frames 9 to move, and it needs to be explained that the conventional support of the steel coil 4 usually only relies on two narrow supports to form line contact, and the stability is limited, the scheme changes the line contact into surface contact through the expansion of the side plates 8, the support area is significantly increased, and thus the overturning risk of the steel coil 4 due to high gravity center and narrow base during acceleration, deceleration or vibration is effectively reduced.

[0030] Further, the connecting rods in the scheme drive the U-shaped frames 9 to lift at the same time and make the side plates 8 move towards the direction of the steel coil 4, so as to increase the contact area of the steel coil 4 and the support surface, avoid that the distance between the support tables 7 is insufficient to support the steel coil 4, assist the support of the steel coil 4, and thus improve the stability of the steel coil 4 during movement, the connecting rods drive the U-shaped frames 9 to descend at the same time and make the side plates 8 move towards the direction of the self-walking sub-car 3, so that the maximum distance between the two groups of side plates 8 is less than the distance between the two groups of saddle seats 5001 and the side plates 8 at the same horizontal plane, and thus the self-walking sub-car 3 is facilitated to move out of the inside of the storage cavity 5005.

[0031] In the scheme, it needs to be explained that the steel coil 4 is usually cylindrical, heavy and has a high gravity center, when the steel coil 4 is horizontally placed, the contact area of the steel coil 4 and the support surface is only a narrow arc surface or line contact, which leads to a very small actual support area, and such limited contact area cannot provide enough stable torque to resist external disturbance, during movement (when the steel coil 4 enters or exits the storage cavity 5005), the steel coil 4 will be subjected to external forces such as acceleration, inertial force, vibration or impact, these external forces will generate overturning torque, when the overturning torque exceeds the restoring torque, the steel coil 4 will be overturned, in addition, the circular cross section of the steel coil 4 may produce swing during rolling, which further aggravates the instability, therefore, the scheme increases the support area of the steel coil 4 through the side plates 8, so as to improve the stability of the steel coil 4 during movement, however, after the side plates 8 are added, due to the small space inside the storage cavity 5005 and the influence of the saddle seats 5001, how to ensure that the self-walking sub-car 3 can still enter and exit the storage cavity 5005 after the side plates 8 are added will be the core problem of the scheme, therefore, the connecting rods drive the side plates 8 and the U-shaped frames 9 to move synchronously to realize the side plates 8 to give way, so as to facilitate the self-walking sub-car 3 to enter and exit the storage cavity 5005.

[0032] As Figure 7 Figure 12 ​As shown, in order to realize the synchronous driving of the side plate 8 and the U-shaped frame 9, the connecting rod provided by the scheme includes a pin shaft 23, an arcuate frame and a lifting plate 13, wherein the pin shaft 23 is fixed between the two groups of U-shaped frames 9, the arcuate frame is rotatably installed on the pin shaft 23, one end of the arcuate frame is hingedly connected with a movable rod 21, the movable rod 21 is hingedly connected with the lower surface of the side plate 8, and the other end of the arcuate frame is rotatably installed with a sliding rod 22. It should be noted that the arcuate frame is composed of a driving rod 14 and a push rod 24, and the driving rod 14 and the push rod 24 are integrally casted, wherein the length of the driving rod 14 is greater than that of the push rod 24, and the included angle between the driving rod 14 and the push rod 24 is obtuse, so that the arcuate frame forms a lever structure with the pin shaft 23 as the fulcrum, thereby improving the supporting force of the side plate 8 and further improving the stability of the steel coil 4 during movement.

[0033] In addition, the lifting plate 13 provided by the embodiment is arranged at the gap between the two groups of U-shaped frames 9, and is provided with a notch and is in sliding connection with the sliding rod 22. By lifting the lifting plate 13, the relative two sliding rods 22 move towards each other, thereby changing the included angle between the driving rod 14 and the horizontal plane, so that the push rod 24 drives the movable rod 21 to move, and further drives the side plate 8 to move, thereby realizing the unfolding or contraction of the side plate 8.

[0034] As shown in Figure 7 Figure 12 In order to realize the lifting of the lifting plate 13, the connecting rod provided by the embodiment further includes a triangular plate 15 and a sliding hinge seat 10. The triangular plate 15 is symmetrically fixed to the lower surface of the lifting plate 13 on both sides, and a slanted groove 19 is formed on the triangular plate 15. The two slanted grooves 19 on the same side form an "eight" shape structure. A sliding column 18 is installed between the two groups of triangular plates 15. The sliding column 18 is preferably in the shape of "H". The sliding column 18 is in sliding connection with the upper surface of the self-propelled trolley 3. A sliding block 20 is installed on one side of the sliding column 18 and is in sliding connection with the slanted groove 19. Since the distance from the sliding block 20 to the bottom of the sliding column 18 is fixed, when the sliding column 18 slides to move the sliding block 20 to the lowest point of the slanted groove 19, the lifting plate 13 rises. When the sliding column 18 slides to move the sliding block 20 to the highest point of the slanted groove 19, the lifting plate 13 descends.

[0035] In order to realize the lifting of the U-shaped frame 9, the sliding hinge seat 10 in the scheme is two groups, and the sliding hinge seat 10 is symmetrically installed on the upper surface of the self-propelled trolley 3. A supporting plate 11 is rotatably installed on the sliding hinge seat 10. The other end of the supporting plate 11 is rotatably installed on the pin shaft 23. By controlling the distance between the two sliding hinge seats 10, the included angle between the supporting plate 11 and the horizontal plane is changed. Specifically, when the distance between the two sliding hinge seats 10 increases, the included angle between the supporting plate 11 and the horizontal plane decreases, and at this time the U-shaped frame 9 descends. When the distance between the two sliding hinge seats 10 decreases, the included angle between the supporting plate 11 and the horizontal plane increases, and at this time the U-shaped frame 9 rises.​

[0036] As Figure 9 - Figure 13 To achieve the distance adjustment between the sliding hinge seats 10 and the relative distance adjustment between the two sliding columns 18, the double-rod hydraulic cylinder 12 is fixed on the self-propelled trolley 3, the telescopic rod 16 is fixed on the sliding column 18, and the telescopic ends of the double-rod hydraulic cylinder 12 and the telescopic rod 16 are fixedly connected with the sliding hinge seat 10 on the same side. The double-rod hydraulic cylinder 12 drives the sliding hinge seat 10 to move, thereby achieving the distance adjustment between the sliding hinge seats 10. The telescopic rod 16 is retracted or extended by the sliding hinge seat 10, and when the telescopic rod 16 is retracted or extended to the limit, the telescopic rod 16 moves synchronously with the sliding hinge seat 10, further driving the sliding column 18 to slide.

[0037] It should be noted that the telescopic rod 16 in the present scheme is preferably composed of a plug barrel 1601 and a hollow plug rod 1602. One end of the hollow plug rod 1602 is inserted into the plug barrel 1601 and is in sliding connection with the plug barrel 1601. The other end of the plug barrel 1601 is rotatably installed with a lead screw 1603, and the plug barrel 1601 is slidably installed with a limiting plate 1604 inside. The limiting plate 1604 is in threaded connection with the lead screw 1603. Rotating the lead screw 1603 causes the limiting plate 1604 to slide in the plug barrel 1601 through the threaded connection between the limiting plate 1604 and the lead screw 1603, thereby adjusting the telescopic amount of the hollow plug rod 1602.

[0038] Specifically, rotating the lead screw 1603 to drive the limiting plate 1604 to move in the plug barrel 1601 can set the initial telescopic amount of the hollow plug rod 1602, so that the device can compensate for manufacturing tolerances, adapt to different specifications of the steel coil 4 or slightly different sizes of the storage location, and ensure that the limit positions of the V-shaped frame lifting 9 and the opening and closing action of the side plate 8 can meet the use requirements, thereby improving the adaptability and reliability of the equipment.

[0039] As Figure 9 - Figure 12 As shown in the drawings, the upper surface of the self-propelled trolley 3 is provided with an adjustment track 3001 in sliding connection with the sliding hinge seat 10, so as to facilitate the movement of the sliding hinge seat 10. The middle section of the adjustment track 3001 is provided with a limiting slide rail 17, which is in sliding connection with the lower end of the sliding column 18, so as to facilitate the movement of the sliding column 18.

[0040] As Figure 3 , Figure 4 and Figure 5As shown, in order to facilitate the movement of the side plate 8, the distance between the two adjacent saddle seats 5001 in the scheme is greater than the distance between the two groups of V-shaped frames 9 on the same support assembly, so that the side plate 8 moves between the two adjacent saddle seats 5001, and the side plate 8 can be unfolded or retracted between the two adjacent saddle seats 5001, thereby facilitating the self-walking child car 3 to enter and exit the storage cavity 5005 in the three-dimensional warehouse 5.

[0041] As shown in Figure 3 , Figure 7 As shown, in order to realize the positioning of the self-walking child car 3 when entering and exiting the storage cavity 5005, the hydraulic lifting child-car 1 provided by the application is provided with a mother car lifting platform 2 at the upper end, both ends of the mother car lifting platform 2 are fixed with guide blocks 2002, recesses 2003 are formed at the middle positions of the lower surfaces of the guide blocks 2002, the outer side of the three-dimensional warehouse 5 is provided with a warehouse outer track 5002 at the lower end of the storage cavity 5005, the bottom of the warehouse outer track 5002 is provided with a positioning protrusion 5003, a reset spring is installed between the bottom of the positioning protrusion 5003 and the three-dimensional warehouse 5, the reset spring is relaxed to push the positioning protrusion 5003 to move towards the inside of the recess 2003, preferably, a contact switch male head is provided on the positioning protrusion 5003, and a contact switch female head is installed inside the recess 2003, and the contact switch female head can output power through system control, when selecting a corresponding storage cavity 5005, the contact switch female head is connected to the power output, the contact switch male head is in contact with the contact switch female head, the circuit is connected, and the self-walking child car 3 is further triggered to enter the storage cavity 5005, in addition, the positioning protrusion 5003 and the recess 2003 are both arc-shaped structures, so as to facilitate the self-walking child car 3 to drive the guide blocks 2002 on the mother car lifting platform 2 to slide inside the warehouse outer track 5002 during walking, until the positioning protrusion 5003 on the warehouse outer track 5002 is moved to the inside of the recess 2003 under the action of the elastic force of the reset spring, thereby realizing the positioning of the self-walking child car 3.

[0042] As shown in Figure 2 , Figure 5 and Figure 7 As shown, the minimum distance between the two adjacent groups of warehouse outer tracks 5002 on the three-dimensional warehouse 5 is the same as the distance between the two guide blocks 2002, so as to facilitate the cooperation between the guide blocks 2002 and the warehouse outer track 5002, of course, in order to facilitate the selection of the height of the warehouse, the guide blocks 2002 can also be driven to adjust the extension amount by setting an electric telescopic rod, when the guide blocks 2002 are retracted, the maximum distance between the two guide blocks 2002 is less than the minimum distance of the warehouse outer track 5002, which can further adjust the height of the hydraulic lifting child-car 1 to adapt to the height of the corresponding warehouse, when the guide blocks 2002 are extended and cooperate with the warehouse outer track 5002, the rapid positioning of the self-walking child car 3 can be realized.

[0043] For the convenience of the hydraulic lifting mother-child car 1, the embodiment is provided with the mother car walking track 6 which is in sliding connection with the hydraulic lifting mother-child car 1 between the adjacent two groups of stereoscopic warehouses 5, for the convenience of the self-walking child car 3, the embodiment is provided with the child car walking track 2001 which is in sliding connection with the self-walking child car 3 on the upper surface of the mother car lifting platform 2, and the I-shaped steel is symmetrically installed on the bottom of the storage cavity 5005 to improve the supporting strength of the storage cavity 5005, and the in-warehouse track 5004 which is in sliding connection with the self-walking child car 3 is arranged on the upper surface of the I-shaped steel to facilitate the self-walking child car 3 to enter and exit the storage cavity 5005.

[0044] In use (when working), when the steel roll 4 enters the warehouse, the height of the warehouse position is selected first to adjust the height of the hydraulic lifting mother-child car 1, the hydraulic lifting mother-child car 1 is moved through the mother car walking track 6, the mother car walking track 6 is moved to the position of the corresponding storage cavity 5005, at this time, the guide block 2002 cooperates with the outer-warehouse track 5002, the position of the hydraulic lifting mother-child car 1 on the mother car walking track 6 is adjusted, until the positioning protrusion 5003 on the outer-warehouse track 5002 is moved to the inside of the groove 2003 under the action of the elastic force of the reset spring, so that the positioning of the self-walking child car 3 is realized, at this time, the child car walking track 2001 is aligned with the in-warehouse track 5004, the self-walking child car 3 is driven, the self-walking child car 3 is moved to the in-warehouse track 5004 through the child car walking track 2001, and the self-walking child car 3 enters the inside of the storage cavity 5005.
