[0024] In order to achieve the purpose of carrying pallets that need to be transported across layers, refer to Figure 2 The bearing mechanism 8 includes a car 81, and the lower front end and the lower rear end of the outer surface of the car 81 are symmetrically provided with locking holes 82 that communicate with the outside world, which can cooperate with the corresponding latch 104 to fix the limit plate 102.

[0025] In order to achieve the purpose of rapid loading and unloading of pallets and other goods, refer to Figure 2 The transmission mechanism 9 includes a bearing shell 91, and a plurality of rotating rollers 92 are rotatably connected to the inner cavity of the bearing shell 91 at intervals, and the lower end of the outer surface of the bearing shell 91 is fixedly connected to the bottom wall of the inner cavity of the car 81.

[0026] When a pallet that needs to be transported across floors is loaded into the inner cavity of the car 81, it can be made to slide along the upper outer surface of several rotating rollers 92, which facilitates the loading and unloading of the pallet and protects the bottom of the pallet to avoid damage caused by direct friction with the bottom wall of the inner cavity of the car 81.

[0027] In order to limit the position of pallets and other goods during the lifting process, refer to Figure 2The limiting mechanism 10 includes a U-shaped plate 101, the inner cavity of the U-shaped plate 101 is slidably connected to a limiting plate 102, the left and right ends of the limiting plate 102 are symmetrically fixedly connected with fixed blocks 103, the middle parts of the two fixed blocks 103 are slidably connected with pins 104, and the rear end of the outer surface of the U-shaped plate 101 is fixedly connected to the lower part of the front end of the outer surface of the car 81.

[0028] After the pallet is loaded into the inner cavity of the car 81 along the upper part of the several rotating rollers 92, the two limit plates 102 are driven to slide upward along the corresponding U-shaped plates 101 to the desired position by pushing the fixing block 103 upward, and then the positions of the two limit plates 102 are fixed by inserting the corresponding pins 104 into the inner cavity of the corresponding locking holes 82, so that the two limit plates 102 can limit the pallet loaded in the inner cavity of the car 81, thereby preventing the pallet from sliding along the upper surface of the several rotating rollers 92 during the lifting process of the car 81.

[0029] In order to achieve the purpose of fixedly connecting the output end of the wire roller 53, refer to Figure 3 The connecting mechanism 6 includes a connecting block 61, and a steel belt sleeve member 62 is fixedly connected to the middle of the inner cavity of the connecting block 61, which can achieve the function of stably connecting the output end of the wire roller 53 through the steel belt sleeve connection method in the prior art.

[0030] In order to achieve the purpose of driving the sliding mechanism 7 to slide up and down in the inner cavity of the four support columns 2, refer to Figure 3 The sliding mechanism 7 includes a connecting plate 71, and the four corners of the connecting plate 71 are provided with mounting grooves 72 communicating with the outside world. The inner cavities of the four mounting grooves 72 are rotatably connected with rollers 73, and the four rollers 73 are respectively slidably connected to the inner cavities of the corresponding slide grooves 21. The middle part of the upper end of the outer surface of the connecting plate 71 is fixedly connected to the lower end of the outer surface of the connecting block 61.

[0031] When the connecting plate 71 is moving up and down, the four rollers 73 will slide up and down along the inner cavity of the corresponding slide groove 21, thereby reducing the friction between the connecting plate 71 and the support column 2 and improving the working efficiency of the device.

[0032] In order to achieve the purpose of driving the sliding mechanism 7 and the bearing mechanism 8 to perform lifting and lowering adjustment under the drive of the driving motor 4, refer to Figure 4 The lifting assembly 5 includes two support frames 51, which can realize the function of stably supporting the wire roller 53.

The outer surface of the rotating shaft 52 is fixedly connected to the wire roller 53, and the left end of the outer surface of the rotating shaft 52 is fixedly connected to the output end of the piston rod of the right part of the driving motor 4, and the output end of the wire roller 53 is fixedly connected to the inner cavity of the steel belt sleeve 62.

[0033] When the car 81 needs to be raised or lowered, the driving motor 4 is driven to drive the rotating shaft 52 to rotate, so that the output end of the wire roller 53 passes through the rectangular through groove 31 to pull the connecting block 61 upward, and the pallet that needs to be transported across floors is raised or lowered through the connection of the connecting plate 71.

[0034] It should be noted that the specific installation method of the drive motor 4, the circuit connection method and the control method in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0035] The working principle of the utility model is as follows: first, the pallet that needs to be transported across floors is loaded into the inner cavity of the car 81 along the upper part of a plurality of rotating rollers 92, and the limit plate 102 is slid upward to the required position, and then the positions of the two limit plates 102 are fixed by inserting the corresponding pins 104 into the corresponding inner cavities of the locking holes 82, so that the pallet loaded in the inner cavity of the car 81 can be limited. At this time, the driving motor 4 is driven so that the output end of the wire roller 53 passes through the rectangular through groove 31 to pull the car 81 upward for lifting and lowering adjustment. When adjusted to the required floor, the two pins 104 on the side close to the floor are pulled out from the two corresponding inner cavities of the locking holes 82, thereby canceling the limit of the pallet by the limit plate 102, and then the pallet can be unloaded along the plurality of rotating rollers 92.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
