The four sprockets 103 are sequentially connected for transmission through a transmission chain 104. The transmission chain 104 is driven by a motor 105 arranged on one side of the base 101, and each trapezoidal screw 102 is connected to the lifting nut 106 above the base 101 by threads. , the four lifting nuts 106 are fixedly connected to a lifting platform 107 at the same time. The trapezoidal screw 102 and the base 101 are rotatably connected through a bearing 108 .

In this embodiment, a chain is used to connect 4 sets of trapezoidal screw rods to ensure the simultaneous lifting of the trapezoidal screw rods. The structure is simple and compact, the total height is lower than that of similar products, the load capacity is large, the lifting is stable, and the lifting stroke is high and adjustable. , can be adapted to a variety of working conditions, the lifting structure can be equipped with other structures, so as to expand into a conveyor with lifting function, see steering conveying structure. During the specific operation, driven by the motor, the transmission chain is driven to rotate, thereby driving the trapezoidal lead screw to rotate. Since the trapezoidal lead screw is installed on the base through the rotating shaft, a lifting nut is installed on the trapezoidal lead screw, and the lifting nut is fixed on the lifting platform at the same time and cannot be rotated. , so that the lifting nut realizes the lifting action, and because of the use of the same specification of the trapezoidal screw, the synchronous lifting operation is realized.
