Description

Technical Field

[0001] The present invention relates to the technical field of cargo storage racks, and in particular to a cargo storage rack for logistics distribution. Background Art

[0002] Logistics and distribution are the core links in the modern supply chain system, which refers to the whole process of efficiently and accurately delivering goods from the supply side to the demand side through systematic planning. The storage process of goods in the logistics and distribution link is a vital basic link in modern supply chain management. Steel coils, as key raw materials in the field of metal materials, occupy an important position in the industrial logistics and transportation system. Therefore, steel coils are a typical representative of bulk cargo transportation.

[0003] The existing cargo storage racks have the following defects in actual use:

[0004] Steel coils are usually bundled in a standardized cylindrical shape and a multi-layer storage architecture is used for three-dimensional warehousing management. In actual operation scenarios, due to the large size and high deadweight of a single steel coil, its high-altitude storage operation has significantly exceeded the carrying capacity of manual operations and forklift equipment, and must rely on bridge cranes for lifting and transportation. However, in actual operations, the steel coils in a suspended state are prone to continuous swinging due to the inertia moment. Their dynamic balance characteristics lead to a significant increase in the time consumption for precise positioning, seriously affecting the efficiency of warehousing operations. There are significant safety risks in the lifting operation of bridge cranes: first, the swinging steel coils are prone to collision accidents in crowded areas. Second, the contact surface between the sling and the steel coil is prone to stress concentration, and there is a risk of sudden slippage. Third, the overlapping area between the operator's blind spot and the equipment's operating trajectory constitutes a high-risk operating space. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of significant safety risks in the high-altitude storage of steel coils in the prior art, and to propose a cargo storage rack for logistics distribution.

[0013] a mounting plate fixed to the bracket;

[0014] a second motor fixed to the mounting plate;

[0015] A worm screw mounted on the mounting plate and driven by the second motor is rotatably engaged with the worm wheel.

[0016] Preferably, a baffle is fixed on one side of the figure-eight support plate, the upper surface of the base is inclined downward toward the baffle, the inner bottom end of the figure-eight support plate is an arc structure corresponding to the steel coil, the figure-eight support plate located on the base is a solid structure, and the figure-eight support plate located on the placement plate is a hollow structure with an opening on one side.

[0017] Preferably, a guide groove is provided on the guide slide, and a guide slider slidably connected to the guide groove is fixedly connected to the inner wall of the figure-eight support plate on the placement plate, and the side of the figure-eight support plate on the placement plate where the baffle is not provided is inclined at 45° toward the direction of the guide slide.

[0018] Preferably, the guide slide is slidably sleeved with a resistance plate for resisting and limiting the steel coil on the side away from the figure-eight support plate, the guide channel is fixedly connected with a guide plate on the side away from the figure-eight support plate, the guide plate is slidably sleeved with a limit rod penetrating through and extending to the position above the resistance plate, the lower end of the limit rod is fixedly connected with a push plate, and a return spring is fixedly connected between the push plate and the guide plate.

[0020] Preferably, a mounting groove is provided on the placement plate, a hydraulic cylinder is fixedly installed in the mounting groove, and a connecting plate is fixedly connected between the output end of the hydraulic cylinder and the guide slideway.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The present invention uses an eight-shaped support plate to place the steel coil, thereby limiting the left and right sides of the steel coil, and uses a baffle to interfere with the rear side of the steel coil to limit the position, thereby ensuring the stability of the rear side of the steel coil, and using the surface inclination of the base and gravity to prevent the steel coil from moving forward and leaving the eight-shaped support plate, which helps to ensure the stability of the steel coil on the storage rack.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 6 , a cargo storage rack for logistics distribution, the cargo storage rack includes a connected bracket 1 and a base 2, a sliding cavity 7 is opened at the bottom end of the base 2, a support seat 8 is slidably sleeved in the sliding cavity 7, a first motor 9 is fixedly installed on the outer wall of the base 2, and a bidirectional lead screw 10 driven to rotate by the first motor 9 is rotatably installed in the sliding cavity 7. It should be noted that: the bidirectional lead screw 10 is equipped with a lead screw protection cover, which is a well-known technology in the prior art field, so it is not described in detail. Two nuts 11 are equipped on the bidirectional lead screw 10, and a connecting rod 12 is pin-connected between the two nuts 11 and the support seat 8. The bidirectional lead screw 10 and the two nuts 11 control the support seat 8 to move horizontally through the connecting rod 12, thereby increasing the contact area between the cargo storage rack and the ground, which helps to reduce the overturning moment generated when loading steel coils, thereby improving the overall stability of the cargo storage rack.

[0034] A rotating disk 3 is rotatably mounted on the bracket 1, a placement plate 4 is fixedly mounted on the rotating disk 3, at least one placement plate 4 is provided, a driving assembly for driving the placement plate 4 to rotate is provided on the bracket 1, an eight-shaped support plate 5 for supporting the steel coil is installed on the base 2 and the placement plate 4, a storage groove 13 for accommodating the driving assembly is provided on the placement plate 4, and a working space is provided for the driving assembly through the storage groove 13 to ensure the normal operation of the driving assembly.

[0035] The driving assembly includes a mounting shaft 14, a worm gear 15, a mounting plate 16, a second motor 17 and a worm 18, and the components are arranged as follows:

[0036] The mounting shaft 14 is rotatably mounted on the receiving groove 13, the worm wheel 15 is fixedly sleeved on the mounting shaft 14, the mounting plate 16 is fixed on the bracket 1, the second motor 17 is fixed on the mounting plate 16, the worm 18 is rotatably mounted on the mounting plate 16, and the worm 18 is driven by the second motor 17, the worm 18 is meshed with the worm wheel 15, and the drive assembly adopts a worm gear transmission system composed of the worm 18 and the worm wheel 15, through its unique reverse self-locking characteristics and high transmission ratio advantages, a double safety guarantee mechanism is realized. First, the self-locking characteristics of the worm gear mechanism can effectively prevent It prevents the placement plate 4 from unexpectedly rotating under the action of gravity, ensuring the stability of the posture after any angle adjustment; secondly, the high transmission ratio design of 1:30 enables the rotating mechanism to obtain precise speed ratio control, and reduces the rotation speed of the placement plate 4 to 0.8° / s, thereby significantly reducing the motion inertia (the moment of inertia is reduced by 82%). This double protection mechanism ensures that the steel coil will not be positioned offset due to inertial impact during loading and unloading, ensuring that the central axis of the steel coil and the V-shaped positioning groove of the eight-shaped support plate 5 are always precisely aligned with ±2mm, effectively avoiding the risk of separation.

[0037] The eight-shaped support plate 5 located on the base 2 is a solid structure, and the eight-shaped support plate 5 located on the placement plate 4 is a hollow structure with an opening on one side. A baffle 19 is fixed on one side of the eight-shaped support plate 5, and the baffle 19 and the eight-shaped support plate 5 are used to limit the rear side and the left and right sides of the steel coil. It should be noted that the side where the steel coil contacts the baffle 19 is the rear side, and the side where the steel coil does not contact the baffle 19 is the front side. The upper surface of the base 2 is tilted downward in the direction of the baffle 19, so that when the steel coil is on the base 2, it will be affected by gravity and move in the direction of the baffle 19 and The baffle 19 is movable against the steel coil on the base 2 to prevent the steel coil from moving toward the front end of the eight-shaped support plate 5 due to external force. The eight-shaped support plate 4 adopts a contoured arc structure design, and the curvature of the inner bottom end surface forms a precise geometric match with the outer contour of the steel coil. The contour design increases the contact area with the steel coil so that the supporting force is evenly distributed on the radial section of the steel coil, effectively reducing the local stress concentration phenomenon and forming a self-centering effect, ensuring the position stability of the steel coil under dynamic load, helping to reduce the micro-friction of the contact surface, and thereby improving the surface quality protection of the steel coil.

[0038] A guide slide 6 for assisting the loading and unloading of steel coils is slidably mounted in the eight-shaped support plate 5 on the placement plate 4. The side of the eight-shaped support plate 5 on the placement plate 4 where the baffle 19 is not provided is inclined at 45° in the direction of the guide slide 6 to provide movement space for the steel coil to move from the guide slide 6 to the eight-shaped support plate 5. A mounting groove 25 is provided on the placement plate 4. A hydraulic cylinder 26 is fixedly installed in the mounting groove 25. A connecting plate 27 is fixedly connected between the output end of the hydraulic cylinder 26 and the guide slide 6. A guide groove is provided on the guide slide 6. A guide slider slidably connected to the guide groove is fixedly connected to the inner wall of the eight-shaped support plate 5 on the placement plate 4. The movement trajectory of the guide slide 6 is limited by the guide groove and the guide slider, so as to ensure the singleness of the movement trajectory of the guide slide 6. At the same time, the radial deviation of the piston rod of the hydraulic cylinder 26 is limited by the guide slider and the guide groove. When the hydraulic cylinder 26 moves When the stroke is long, the guide slider can share part of the axial pressure and reduce the risk of piston rod instability. The guide slide 6 is controlled by the hydraulic cylinder 26 to perform telescopic movement. At the same time, the driving component cooperates with the driving component to control the angle adjustment of the placement plate 4 to achieve the angle adjustment of the eight-shaped support plate 5, so that the guide slide 6 can extend outward while deflecting downward to contact the ground, so that the staff can complete the high-altitude steel coil loading operation at a low place. The hydraulic cylinder 26 is responsible for the linear telescopic movement of the guide slide 6 as the main driving unit. The synchronously linked driving component realizes the angle adjustment of the placement plate 4 through the worm gear mechanism, and then controls the angle adjustment of the eight-shaped support plate 5 and the guide slide 6 located on the placement plate 4. The above-mentioned "telescopic-pitching" double action combination is used to achieve the progressive contact between the guide slide 6 and the ground, thereby converting the original high-altitude storage operation of the steel coil into a ground safety operation, which helps to reduce the risk of accidents.

[0039] The guide slide 6 is slidably sleeved with a resistance plate 20 for resisting and limiting the steel coil on the side away from the eight-shaped support plate 5. The resistance plate 20 ensures the stability of the high-altitude steel coil during loading and unloading, and prevents the steel coil from escaping from the guide slide 6 and causing safety hazards to the surrounding staff. A limited slide rail is provided on the resistance plate 20, and the guide slide 6 is fixedly connected with a limit slider slidably connected to the guide slide rail on the side away from the eight-shaped support plate 5, so as to ensure the singleness of the movement trajectory of the resistance plate 20. The guide channel 6 is fixedly connected with a guide plate 21 on the side away from the eight-shaped support plate 5, and the guide plate 21 is slidably sleeved with a limit rod 22 that penetrates and extends to the upper position of the contact plate 20. The lower end of the limit rod 22 is fixedly connected with a push plate 23, and a reset spring 24 is fixedly connected between the push plate 23 and the guide plate 21. Through the elastic force of the reset spring 24, the limit rod 22 tends to move to the initial state when not affected by external force.

[0040] The present invention can be explained by the following operation mode:

At this time, the steel coil is fixed by the fork and the guide slide 6. After the staff is away from the steel coil, the second motor 17 is started to drive the installation shaft 14 to rotate through the meshing connection between the worm 18 and the worm wheel 15. The installation shaft 14 drives the placement plate 4 to rotate, and the placement plate 4 drives the eight-shaped support plate 4 to deflect downward by 15°. At the same time, the staff controls the forklift to continue moving forward until the fork moves from one end of the steel coil to the other end, and finally the steel coil is taken away from the shelf by the forklift.
