Description
Technical Field
[0001] The utility model relates to the technical field of transportation protection, in particular to an anti-collision protection device for goods in logistics transportation. Background Art
[0002] With the growth of global trade and the rise of e-commerce, the volume of logistics transportation has increased significantly. Goods are frequently transferred during transportation, loading, unloading, warehousing and other links, and the risk of collision also rises. The goods transported by modern logistics are of various types, including fragile items, precision instruments, high-value commodities, etc. These goods have high requirements for transportation conditions. Once a collision occurs, it may cause huge economic losses. During the transportation of goods, anti-collision protection devices are generally used to protect the goods in the freight car compartment.
[0003] The conventional protection method is to wrap materials such as rubber pads and foam boards on the surface of the goods or place them at key parts of the transportation equipment. When a collision occurs, it can absorb and disperse the impact force, reduce the damage to the goods, and fix the goods through ropes, straps or fixed brackets to prevent shaking and displacement during transportation.
[0004] However, due to the large number of goods in the freight car compartment, the goods fixed by using fixing methods such as ropes and straps are not firm enough. When the freight car travels on rough roads, collisions between these stacked goods and the inner wall of the compartment still cannot be avoided. In addition, these fixing methods are too cumbersome and waste transportation time. Therefore, an anti-collision protection device for goods in logistics transportation is proposed to solve the above problems. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present invention: A cargo anti-collision protection device in logistics transportation, including a compartment 1. An activity slot 3 is opened inside the top end of the compartment 1. Four slide slots 4 are inclinedly opened at both the upper and lower ends inside the compartment 1. A motor 6 is fixedly connected to the middle of the top end of the compartment 1. The output end of the motor 6 is fixedly connected to a rotating shaft 7. The bottom end of the rotating shaft 7 is fixedly connected to a first bevel gear 8 inside the top end of the activity slot 3. Four second bevel gears 9 are externally meshed with the bottom end of the first bevel gear 8. The far ends of the four second bevel gears 9 are respectively fixedly connected to lead screws 10. The far ends of the lead screws 10 are respectively rotatably connected to the outer ends of the adjacent slide slots 4 at the top. L-shaped plates 12 are arranged at the four corners inside the compartment 1. L-shaped buffer plates 13 are fixedly connected to the inner sides of the four L-shaped plates 12. Slide blocks 11 are fixedly connected to both the upper and lower ends of the L-shaped plates 12. The slide blocks 11 are respectively slidably connected to the adjacent slide slots 4 on the same side. The middle parts of the top L-shaped plates 12 are respectively threadedly connected to the lead screws 10 on the same side. A first connecting plate 14 and a second connecting plate 16 are respectively fixedly connected to the opposite sides of the two groups of left and right L-shaped plates 12. A first buffer plate 15 and a second buffer plate 17 are respectively fixedly connected to the opposite sides of the front and rear first connecting plates 14 and second connecting plates 16. The second connecting plate 16 and the second buffer plate 17 are respectively slidably connected to the first connecting plate 14 on the same side. A telescopic assembly is arranged between the two groups of front and rear L-shaped plates 12. The telescopic assembly is used to push the goods towards the middle.
[0027] The starting motor 6 drives the rotating shaft 7 and the first bevel gear 8 to rotate. Since the second bevel gear 9 is meshed and connected to the bottom end of the first bevel gear 8, when the first bevel gear 8 rotates, it will drive the second bevel gear 9 to rotate. The thread directions of the lead screws 10 are the same, while the rotation directions of the second bevel gears 9 at the left rear end and the right front end are opposite. Therefore, the sliders 11 at the upper left rear end and the right front end drive the L-shaped plates 12 fixed thereto to move in the opposite direction. The rotation directions of the second bevel gears 9 at the left front end and the right rear end are opposite. Therefore, the sliders 11 at the upper left front end and the right rear end drive the L-shaped plates 12 fixed thereto to move in the opposite direction. In this way, the four L-shaped plates 12 can move synchronously towards the center direction of the carriage 1 or move outwards synchronously, and the first connecting plate 14, the second connecting plate 16 and the telescopic assembly contract or stretch synchronously, so as to protect the goods in the middle.
[0028] Refer to Figure 3 , Figure 4 and Figure 5 , the telescopic assembly includes a third connecting plate 18 and a fourth connecting plate 20. The opposite sides of the third connecting plate 18 and the fourth connecting plate 20 are respectively attached to the opposite sides of the front and rear two L-shaped plates 12. A limiting groove 23 is opened at the inner top end of the third connecting plate 18. A limiting block 21 is fixedly connected to the front part of the top end of the fourth connecting plate 20. Buffer plates 19 and 22 are respectively fixedly connected to one ends of the third connecting plate 18 and the fourth connecting plate 20 located in the center direction of the carriage 1. The opposite ends of the left third connecting plate 18 and the fourth connecting plate 20 are respectively fixedly connected to the opposite ends of the left L-shaped plate 12. The opposite ends of the right third connecting plate 18 and the fourth connecting plate 20 are rotatably connected to the top end of the right L-shaped plate 12 through a telescopic rotating rod 28. The fourth connecting plate 20 and the buffer plate 22 are both slidably connected to the third connecting plate 18 on the same side. The limiting block 21 is slidably connected to the limiting groove 23.
[0029] When the front and rear two L-shaped plates 12 move in the opposite direction, the fourth connecting plate 20 and the buffer plate 22 slide in the third connecting plate 18, and the limiting block 21 slides in the limiting groove 23 to limit the sliding range of the fourth connecting plate 20 inside the third connecting plate 18.
[0030] Refer to Figure 1 , Figure 4 and Figure 6 , an extrusion groove 24 is opened at the bottom end of the right third connecting plate 18. A plug 25 is slidably connected to the rear bottom end of the right third connecting plate 18. A spring 26 is fixedly connected to the rear end of the extrusion groove 24. The front end of the spring 26 is fixedly connected to the part of the outer side of the plug 25 inside the extrusion groove 24. A clamping groove 27 is opened at the bottom of the rear end of the right front L-shaped plate 12. The front end of the plug 25 is clamped and connected to the clamping groove 27. A protective shell 5 is fixedly connected to the middle of the top of the carriage 1. The protective shell 5 is located outside the motor 6. A carriage door 2 is rotatably connected to the top right end of the carriage 1.
[0031] Pulling the insertion block 25 backward can squeeze the spring 26 and drive the front end of the insertion block 25 out of the card slot 27, facilitating the rotation of the third connecting plate 18 and the fourth connecting plate 20 for occasional measurement, so that the staff can enter the space formed by the four L-shaped plates 12 to perform the loading operation. When the goods are loaded, the sides of the third connecting plate 18 and the fourth connecting plate 20 that are away from each other are respectively attached to the opposite sides of the right L-shaped plate 12, and the force applied to the insertion block 25 is released. The spring 26 drives the front end of the insertion block 25 to engage with the card slot 27.
[0032] Working principle: When the goods are stacked, the staff comes out of the carriage 1 and rotates the right third connecting plate 18 and the fourth connecting plate 20 so that the sides of the third connecting plate 18 and the fourth connecting plate 20 that are away from each other are respectively attached to the opposite sides of the right L-shaped plate 12. Then, the insertion block 25 is inserted into the inside of the card slot 27, so that the goods are stacked in a closed area. Then, the motor 6 is started to drive the first bevel gear 8 to drive the four second bevel gears 9 to rotate, so that the lead screw 10 rotates to drive the L-shaped plate 12 to move towards the middle of the carriage 1. At the same time, the second connecting plate 16 contracts with the first connecting plate 14, and the third connecting plate 18 contracts with the fourth connecting plate 20, tightly fixing the goods in the middle of the carriage 1 to prevent the goods from moving randomly. The L-shaped buffer plate 13, the first buffer plate 15, the second buffer plate 17, the third buffer plate 19 and the fourth buffer plate 22 provide a certain buffering effect on the goods.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
