Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of logistics automation, in particular to a pallet elevator with four-axis synchronous lifting. Background Art
[0002] With the rapid development of the logistics industry, the requirements for intelligent and automated logistics warehousing are becoming higher and higher. The elevator is used to lift, store and retrieve goods, which greatly improves storage efficiency and space utilization, and also greatly reduces manpower and material resources. However, as the weight of the lifted goods increases, the stability of the elevator cannot be guaranteed during lifting, which can easily cause the goods to tilt or even fall during the lifting process. Utility Model Content
[0003] Purpose of the invention: In view of the above shortcomings, the utility model provides a pallet elevator with four-axis synchronous lifting.
[0004] Technical solution: To solve the above problems, the utility model adopts a four-axis synchronous lifting pallet elevator, including a top frame assembly, a column frame, and a lifting platform. The top frame assembly is installed on the top of the column frame. Four chains are arranged on the column frame. Driving mechanisms are arranged at the four corners of the lifting platform. Each driving mechanism is connected with a sprocket. The sprocket cooperates with the chain to make the lifting platform rise and fall along the chain direction. A spirit level is also arranged on the lifting platform.
[0005] Furthermore, auxiliary wheels are provided on the upper and lower sides of the sprocket, and the chain forms an Ω shape after passing through the auxiliary wheel and the sprocket, with the auxiliary wheel contacting one side of the chain and the sprocket contacting the other side of the chain.
[0006] Furthermore, the driving mechanism includes a motor and a reducer, and the sprocket is connected to the reducer.
[0007] Furthermore, the four sets of driving mechanisms are centrally symmetrically arranged on the lifting platform.
[0008] Furthermore, it also includes a controller, which is used to receive information from the level meter and control the driving mechanism according to the information.
[0009] Furthermore, it also includes a counterweight assembly arranged on the column frame, and the counterweight assembly is connected to the lifting platform through a guide rope.
[0010] Furthermore, the column frame includes four columns, and a chain is provided on the inner side of each column.
[0011] Beneficial effect: Compared with the prior art, the significant advantage of the utility model is that it realizes the smooth lifting of the lifting platform through four sets of driving mechanisms, thereby improving the stability of cargo lifting; at the same time, the state of the lifting platform is detected by a spirit level, and the working state of the motor is adjusted in real time according to the feedback information of the spirit level, so that the lifting platform always remains level. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 3 This is a schematic diagram of the matching structure of the sprocket, auxiliary wheel and chain of the utility model. DETAILED DESCRIPTION
[0015] like Figure 1 As shown, a four-axis synchronous lifting pallet lifter in this embodiment includes a top frame assembly 1, a column frame 2, a counterweight assembly 3, and a lifting platform 4. The column frame 2 includes four columns, and four chains 5 are arranged on the column frame 2. The top frame assembly 1 is installed on the top of the column frame 2, and the counterweight assembly 3 is connected to the lifting platform 4 through a guide rope. Figure 2 As shown, four sets of driving mechanisms are arranged on the lifting platform 4, and the four sets of driving mechanisms are symmetrically arranged on the lifting platform 4. The driving mechanism includes a motor 8 and a reducer 7, and the reducer 7 is connected to a sprocket 6.
[0016] like Figure 3 As shown, auxiliary wheels 10 are provided on the upper and lower sides of the sprocket wheel 6. After the chain 5 passes through the auxiliary wheels 10 and the sprocket wheel 6, an Ω shape is formed, and the auxiliary wheel 10 contacts one side of the chain 5, and the sprocket wheel 6 contacts the other side of the chain 5. The lifting platform 4 is lifted and lowered along the direction of the chain 5 by the cooperation between the sprocket wheel 6 and the chain 5. A level meter 9 is also provided on the lifting platform 4 to sense whether the lifting platform 4 is in a horizontal state.
[0017] The working principle of the utility model is as follows: the motor 8 drives the reducer 7, the reducer 7 drives the sprocket 6 to rotate, and the sprocket 6, the auxiliary wheel 10 and the chain 5 cooperate to make the lifting platform 4 rise and fall along the direction of the chain 5. The four groups of motors rotate forward or reverse synchronously, so that the four corners of the lifting platform 4 can rise and fall synchronously and smoothly. At the same time, the controller also receives the instant detection data of whether the lifting platform 4 is horizontal by the level meter 9, and fine-tunes the single group or multiple groups of motors according to the detection data, so that the lifting platform 4 always maintains a horizontal state, and the cargo lifting process is more stable.
