[0002] Logistics warehousing is used in all walks of life, and faces a variety of cargo forms. Some light cargo is stored in a loose state without packaging. Some cargo requires dust protection on the top. Thin cardboard or plastic bags are added on the top of the cargo. When the stacker runs at high speed, the material will be blown off, affecting its use.

[0003] A solution has been proposed by practitioners, namely the Chinese utility model patent with the publication number "CN 219156433 U" and the name "Anti-dumping device for cargo on a double-column stacker loading platform", which discloses a cargo anti-dumping device that prevents cargo on the stacker loading platform from tipping over by setting movable baffles on both sides of the loading platform to fix the cargo. This prior art solution has some technical deficiencies:

[0004] 1. The airflow generated when the stacker is moving will blow down light goods and cannot effectively protect them.

[0005] 2. The baffle clamps the goods from both sides, which may easily cause damage to the goods and affect the yield rate of the goods. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cargo anti-falling device for a stacker loading platform which has a simple structure, a wide range of applications and can prevent top materials from being blown off and can provide buffering protection for materials.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: a cargo anti-falling device for a stacker loading platform, used to prevent cargo on a rack from falling, comprising a tightening frame slidably arranged in the rack, a plurality of buffer protection components are arranged at the bottom of the tightening frame, and a lifting drive mechanism is arranged on the rack for driving the tightening frame to descend in the rack so that the plurality of buffer protection components can tighten the cargo on the rack.

[0008] As a further improvement of the above technical solution:

[0009] The buffer protection component includes an axial bearing arranged on the jacking frame, a guide rod is inserted into the axial bearing, a protruding pressure block is provided at one end of the guide rod away from the axial bearing, and an elastic member is wound around the guide rod to press the pressure block.

[0010] The lifting drive mechanism includes two rotating rods arranged in parallel and a driving motor for driving the two rotating rods to rotate simultaneously. Cranks are provided at both ends of the rotating rods, and support bearings are provided on the cranks. The support bearings abut against the bottom surface of the top rod of the jacking frame to drive the jacking frame to perform lifting and lowering movements when the rotating rods drive the cranks to rotate.

[0011] The driving motor is arranged between the two rotating rods and is used to drive the two rotating rods to move synchronously. The driving end of the driving motor is provided with a driving pulley, and each of the rotating rods is provided with a driven pulley, and the driven pulley is connected to the driving pulley through a synchronous belt.

[0012] Two fixing plates are arranged on the top of the frame, and rotating bearings are arranged on the fixing plates so that the front and rear ends of each rotating rod are respectively penetrated and installed on the two fixing plates.

[0013] The bottom surface of the push rod of the jacking frame is provided with a wear-resistant part for contacting with the supporting bearing.

[0014] The pressing block is made of polyurethane soft material.

[0015] The frame and the jacking frame are connected through a guide mechanism.

In this embodiment, the jacking frame 2 is constructed of a plurality of aluminum alloy profiles 21.

[0030] The specific implementation principles are as follows:

[0031] When the cargo anti-falling device for the stacker cargo platform is used, the jacking frame 2 moves downward along the frame 1 under the drive of the lifting drive mechanism 3, so that the multiple buffer protection components 22 press the cargo on the stacker cargo platform, on the one hand, to prevent the cargo from tipping over during the movement of the stacker, and on the other hand, compared with the existing anti-tipping device, the anti-falling device is arranged on the top of the frame 1, and applies pressure from the top of the cargo to prevent the airflow generated when the stacker is moving from blowing off the light-weight cargo and the dust-proof film on the top of the cargo. At the same time, since the bottom of the jacking frame 2 is provided with multiple buffer protection components 22, it is prevented that when the jacking frame 2 presses down on the cargo, the pressure is too large, causing damage to the cargo. That is, the cargo anti-falling device for the stacker cargo platform has the advantages of simple structure, wide application range, and can prevent the top material from blowing off and can form buffer protection for the material.

[0032] In this embodiment, the buffer protection assembly 22 includes an axial bearing 221 arranged on the jacking frame 2, a guide rod 222 is inserted into the axial bearing 221, a protruding pressing block 224 is arranged at one end of the guide rod 222 away from the axial bearing 221, and an elastic member 223 (such as a spring, rubber, etc.) is wound around the guide rod 222 to press against the pressing block 224. When in use, the jacking frame 2 drives the buffer protection assembly 22 to move downward, and when the pressing block 224 contacts the goods, the goods transmit the upward thrust to the pressing block 224, and the guide rod 222 moves upward to compress the elastic member 223, and the elastic member 223 generates an elastic force until the pressure on the goods reaches the warning pressure and stops decreasing. At this time, the goods are compressed, which achieves the purpose of preventing the goods from tipping over on the one hand, and on the other hand, the elastic force generated by the elastic member 223 buffers the excessive pressure to avoid damage to the goods due to excessive pressure.

[0033] In this embodiment, the lifting drive mechanism 3 includes two parallel rotating rods 31 and a driving motor 37 for driving the two rotating rods 31 to rotate simultaneously. Both ends of the rotating rods 31 are provided with cranks 32, and the cranks 32 are provided with support bearings 33. The support bearings 33 abut against the bottom surface of the top rod of the jacking frame 2, so as to drive the jacking frame 2 to move up and down when the rotating rods 31 drive the cranks 32 to rotate. The simultaneous rotation of the two rotating rods 31 can make the jacking frame 2 move up and down smoothly, with strong stability.

[0034] In this embodiment, the driving motor 37 is disposed between the two rotating rods 31 and is used to drive the two rotating rods 31 to move synchronously. A driving pulley is disposed at the driving end of the driving motor 37, and a driven pulley 34 is disposed on each rotating rod 31. The driven pulley 34 is connected to the driving pulley through a synchronous belt 35. Through this special structure, only one driving motor 37 is needed to synchronously drive the two rotating rods 31 to move, the manufacturing and maintenance costs are greatly reduced, the weight is lighter, and the driving is also synchronous and stable.

[0035] In this embodiment, two fixing plates 4 are provided on the top of the frame 1, and rotating bearings 36 are provided on the fixing plates 4, so that the front and rear ends of each rotating rod 31 are respectively penetrated and installed on the two fixing plates 4. The fixing plates 4 and the rotating bearings 36 are provided on the frame 1 to prevent the vibration generated by the rotating rod 31 from affecting the operation of the jacking frame 2.

[0036] In this embodiment, the bottom surface of the push rod of the jacking frame 2 is provided with a wear-resistant member 5 for contacting the support bearing 33. This prevents the friction between the support bearing 33 and the jacking frame 2 from affecting the life of the components.

[0037] In this embodiment, the pressing block 224 is made of polyurethane soft material to further protect the goods and prevent them from being damaged.

[0038] In this embodiment, the frame 1 is connected to the jacking frame 2 through a guide mechanism 6. In this embodiment, the guide mechanism 6 includes a guide rail 61 vertically arranged on the frame 1, and a slider 211 corresponding to the guide rail 61 is arranged on the jacking frame 2. The slider 211 cooperates with the guide rail 61 of the frame 1, so that the jacking frame 2 moves up and down along the guide rail 61 smoothly.
