DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] An embodiment provided by the utility model: Figure 1 As shown, a stacker suitable for a low-temperature cold storage includes an operating cabin 1, a base 2, a lifting support frame 3, a hydraulic column 4 and a moving frame mechanism 5.

[0026] The mobile frame mechanism 5 includes an outer frame assembly 51, such as Figure 2 As shown, the outer frame assembly 51 includes a lifting connection piece 516, which is fixed at the top position on both sides of the fourth layer frame 514, and the output end of the hydraulic column 4 is fixedly connected to the lifting connection piece 516. The mobile frame mechanism 5 forms a lifting structure with the lifting support frame 3 through the hydraulic column 4. When the stacker moves goods up and down in the low-temperature cold storage, the staff operates the device in the operating cabin 1, and the hydraulic column 4 drives the position of the lifting connection piece 516 of the mobile frame mechanism 5. The left and right groups of hydraulic columns 4 work at the same time, realizing the process of the entire mobile frame mechanism 5 being stably lifted up and down, and completing the handling of goods on the cold storage shelves.

[0027] like Figure 3 As shown, the outer frame assembly 51 includes a first layer frame 511, a second layer frame 512, a third layer frame 513, a fourth layer frame 514 and a frame connector 515. The first layer frame 511, the second layer frame 512, the third layer frame 513 and the fourth layer frame 514 are vertically distributed, and two adjacent groups are fixedly connected by the frame connector 515. The device is provided with multiple layers of frames, which are respectively fixed by multiple groups of frame connectors 515, ensuring that the device can transport multiple groups of goods at the same time, increasing the utilization rate of the device and improving the transportation efficiency of the stacker.

[0028] The mobile rack mechanism 5 includes a transport and storage base plate 52, such as Figure 3As shown, the first layer frame 511, the second layer frame 512, the third layer frame 513 and the fourth layer frame 514 are all provided with grooves at the inner lower side, and four groups of transport and storage bottom plates 52 are provided, and they are plugged and connected with the grooves of the first layer frame 511, the second layer frame 512, the third layer frame 513 and the fourth layer frame 514 respectively, and the shape of the transport and storage bottom plates 52 matches the grooves. The transport and storage bottom plates 52 at the bottom of each layer frame are used to place the transported goods. When the size of the transported goods is high, the transport and storage bottom plates 52 of the upper layer frame can be disassembled. The structure of the mobile frame mechanism 5 is flexible and changeable, and the spatial height of each layer frame can be changed according to the transported object, which is suitable for the use of a variety of goods.

[0029] like Figure 3 As shown, the mobile rack mechanism 5 also includes a cargo transport component 53, and the cargo transport component 53 is provided with two groups, which are respectively located on the inner side of the first layer frame 511 and are symmetrically arranged with respect to the first layer frame 511. The cargo transport components 53 are arranged one by one on the second layer frame 512, the third layer frame 513 and the fourth layer frame 514 in the same manner as the first layer frame 511. During operation, each transport storage base plate 52 of the mobile rack mechanism 5 is moved to the height of the shelf layer where the goods are to be stored, and the cargo transport components 53 of the corresponding layer complete the operation of moving the goods from the shelf to the transport storage base plate 52 of the corresponding layer frame.

[0030] The mobile rack mechanism 5 also includes a cargo bottom plate 54, such as Figure 4 As shown, the cargo transport assembly 53 includes a first hydraulic rod 531, a slide rail 532 and a cargo bottom plate clamping assembly 533. The main body of the first hydraulic rod 531 is fixed on the first layer frame 511, and the output end of the first hydraulic rod 531 is fixed on the cargo bottom plate clamping assembly 533. The cargo bottom plate clamping assembly 533 is slidably connected to the first layer frame 511 through the slide rail 532. When the goods are moved from the mobile rack mechanism 5 to the cold storage shelf, the cargo bottom plate clamping assembly 533 clamps the cargo bottom plate 54, and the left and right two groups of first hydraulic rods 531 respectively drive the cargo bottom plate clamping assembly 533 to slide on the outside of the device, and when it reaches the appropriate position, the cargo bottom plate clamping assembly 533 releases the cargo bottom plate 54 to the shelf; when the goods are moved from the cold storage shelf to the mobile rack mechanism 5, the cargo bottom plate clamping assembly 533 clamps the cargo bottom plate 54, and the left and right two groups of first hydraulic rods 531 respectively drive the cargo bottom plate clamping assembly 533 to slide on the inside of the device, and when it reaches above the transport storage bottom plate 52, the cargo bottom plate clamping assembly 533 releases the cargo bottom plate 54 to the transport storage bottom plate 52.

[0031] like Figure 5 and Figure 6As shown, the cargo bottom plate clamping assembly 533 includes a side plate 5331, a second hydraulic rod 5332, a lifting plate 5333, a telescopic member 5334 and a cargo bottom plate supporting member 5335. The fixed end of the second hydraulic rod 5332 is fixed inside the side plate 5331, the output end of the second hydraulic rod 5332 is connected to the lifting plate 5333, the lifting plate 5333 is movably connected to the side plate 5331, the side of the lifting plate 5333 is fixedly connected to the telescopic member 5334, one end of the telescopic member 5334 is installed with a cargo bottom plate supporting member 5335, and the cargo bottom plate supporting member 5335 is movably connected to the lifting plate 5333. The cargo bottom plate 54 in the cold storage is of uniform size. When the cargo bottom plate clamping assembly 533 is to clamp the cargo bottom plate 54, the telescopic member 5334 drives the cargo bottom plate support member 5335 to move to the position below the cargo bottom plate 54, and the second hydraulic rod 5332 drives the lifting plate 5333 to move upward as a whole, so that the cargo bottom plate support member 5335 moves upward, and lifts the cargo bottom plate 54 from the cargo placement platform position, which is convenient for the next moving operation; when the cargo bottom plate clamping assembly 533 releases the cargo bottom plate 54, the second hydraulic rod 5332 drives the lifting plate 5333 to move downward as a whole, and the cargo bottom plate support member 5335 moves downward, so that the bottom surface of the cargo bottom plate 54 contacts the placement platform, and the cargo bottom plate support member 5335 continues to move downward to a certain position, and the telescopic member 5334 drives the cargo bottom plate support member 5335 to move to a position outside the cargo bottom plate 54. The mechanized transportation operation of the cargo bottom plate 54 and the goods above is realized, and the working process is simple and efficient. The clamping and releasing function of the cargo floor clamping assembly 533 reduces the wear on the bottom surface thereof compared to directly pushing the cargo or cargo floor 54 .

[0032] like Figure 6 As shown, the side edge of the cargo bottom plate 54 matches the cargo bottom plate support 5335. A plurality of cargo bottom plate support members 5335 support the cargo bottom plate 54, so that the force is evenly distributed, the cargo bottom plate 54 is kept in a balanced state, and the cargo bottom plate 54 is stably supported during the handling process to protect the safety of the transported cargo.
