Description

Technical Field

[0001] The present application relates to the technical field of cargo stacking in cold storage, and in particular to a cold storage shelf and a safe cold storage handling system. Background Art

[0002] Currently, in cold storage, goods are generally placed directly on pallets, and the pallets are placed directly on the floor of the cold storage, which easily leads to a waste of space in the cold storage.

[0003] In order to improve the utilization of the space in the cold storage, goods can be stacked up and down. However, when the goods are stacked for a long time, the goods on the lower layer will be compressed and deformed, which may cause the goods on the upper layer to collapse and injure the operators. Therefore, there is a possibility that this problem needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a cold storage shelf and a safe cold storage handling system to improve the safety of goods after stacking in the cold storage and reduce the risk of goods hitting operators.

[0005] In the first aspect, the present application provides a cold storage shelf adopting the following technical solution:

[0006] A cold storage shelf includes a support frame, wherein the support frame is provided with an upwardly extending protective frame, and multiple protective frames are arranged in sequence at intervals along the length direction of the support frame; a support rod is provided on the side close to each other of two adjacent protective frames, and multiple support rods are arranged in sequence at intervals along the up and down directions; two support rods located between two adjacent protective frames and at the same height position jointly support a pallet, and the pallet is used to support goods.

[0007] By adopting this technical solution, the support rods support the pallet, which in turn supports the cargo. This allows the cargo to be stacked vertically, fully utilizing the space within the cold storage and facilitating forklift transfers. The support rods and pallet work together to separate the cargo vertically, thereby reducing the risk of compression and deformation. Furthermore, the protective frame provides a barrier to the cargo, minimizing the possibility of cargo falling and injuring operators.

[0008] Optionally, the support frame includes a base and a support column for supporting the base, and the protective frame is connected to the base; a gap is provided between the base and the ground for pedestrians or vehicles to walk.

[0009] By adopting the above technical solution, the support columns separate the base from the ground, allowing pedestrians or vehicles to walk on it, making it easier for operators or transfer vehicles to quickly reach the location of the goods to be transported, which is conducive to improving the efficiency of cargo handling. At the same time, the ground below the base can also be used to place goods, thereby reducing the possibility of wasted space in the cold storage.

[0010] Optionally, an isolation grid is provided at a position between two adjacent protective frames on the support column, and a connecting component for fixing the isolation grid is provided between the isolation grid and the support column; the isolation grid is located at the end of the base along the length direction of the support rod.

[0011] By adopting the above technical solution, the isolation grid can block pedestrians or vehicles to reduce the risk of pedestrians or vehicles located below the base being accidentally injured by contact with vehicles or goods during loading and unloading.

[0012] Optionally, the isolation grid is rotatably connected to one of the support columns, and the connecting assembly includes a fixed sleeve connected to the other support column, a fixed rod inserted into the fixed sleeve, and a mating sleeve connected to the isolation grid; the mating sleeve is located below the fixed sleeve, and the mating sleeve is used to be plugged in and mated with the fixed rod.

[0013] By adopting the above technical solution, the fixing rod and the matching sleeve are plugged into each other to limit the rotation of the isolation grid and fix the isolation grid. When the isolation grid needs to be rotated, the fixing rod is pushed upward to separate the fixing rod and the matching sleeve, which is simple and convenient to operate.

[0014] Optionally, the position of the support rod can be adjusted in the up and down directions.

[0015] By adopting the above technical solution, the position of the support rod can be adjusted according to the height of the goods, which is conducive to minimizing the distance between two adjacent goods in the vertical direction, so as to further improve the utilization rate of the space in the cold storage.

[0016] In the second aspect, the present application provides a safe cold storage handling system that adopts the following technical solutions:

[0017] A safe cold storage handling system includes a moving device and the above-mentioned cold storage shelves, wherein the moving device is located between two adjacent protective frames; the moving device includes a moving body, a lifting member for abutting against the lower surface of the pallet, and a lifting assembly for driving the lifting member to rise and fall; the protective frame is provided with a moving track for cooperating with the rollers of the moving body, and the length direction of the moving track is arranged along the length direction of the support rod.

[0018] By adopting the above technical solution, after the mobile body moves along the moving track to the position below the designated pallet, the lifting assembly drives the lifting member to rise so that the lifting member can lift the pallet, thereby allowing the mobile body to drive the corresponding pallet to the designated position along the length direction of the support rod.

[0019] Optionally, the lifting member is slidingly connected to the mobile vehicle body along the up and down directions; the lifting assembly includes a rotating rod rotatably connected to the lifting member, a sliding block slidably connected to the mobile vehicle body along the length direction or width direction of the mobile vehicle body, and a driving member for driving the sliding block to slide; the rotating rod extends downward away from one end of the lifting member and is tilted along the sliding direction of the sliding block, and the rotating rod is rotatably connected to the sliding block.

[0020] By adopting the above technical solution, the driving member drives the sliding block to slide, so that the rotating rod rotates relative to the lifting member, and the lifting member can automatically move up or down. The structure is simple and the operation is stable.

[0021] Optionally, the mobile body is provided with a controller and a sensing element for sensing the position of the pallet, and the sensing element, the lifting assembly and the mobile body are all controlled by the controller.

[0022] By adopting the above technical solution, when the mobile body moves to the position of the pallet, the sensing part sends a sensing signal to the controller, and the controller drives the lifting part to move upward through the lifting assembly to lift the pallet; then the controller controls the movement of the mobile body to automatically drive the pallet to the specified position of the support rod, with precise control and a high degree of automation.

[0023] Optionally, a transfer device is also included, which includes a transfer vehicle body, a transfer frame slidingly connected to the transfer vehicle body in the up and down directions, a connecting piece for connecting to the pallet, and a lifting structure for driving the transfer frame to rise and fall, and the connecting piece is connected to the transfer frame.
