Referring to fig. 3, the cylinder power module 2 is a rodless cylinder power module, and includes a rodless cylinder 21, a cylinder back plate 22, a synchronous pulley 23, a synchronous pulley fixing shaft 24, an upper fixing plate 25, a lower fixing plate 26, a first guide rail 27, a first slider 28 and a first guide rail fixing profile 29, where the number of the first guide rail fixing profiles 29 is two, the two first guide rail fixing profiles 29 are respectively disposed on two sides of the rodless cylinder 21, the two first guide rail fixing profiles 29 are parallel to each other and have the same structure, the first guide rail 27 is disposed on the first guide rail fixing profile 29, each first guide rail fixing profile 29 is provided with one first guide rail 27, each first guide rail 27 is provided with one first slider 28, and the cylinder back plate 22 is respectively connected and fixed to the first slider 28 and a piston plate of the rodless cylinder 21. Because the guide performance of the rodless cylinder 21 is poor, the guide performance of the structure of the rodless cylinder 21 can be enhanced by the first guide rail 27 and the first slide block 28 arranged on the two sides of the rodless cylinder, the function of protecting the cylinder is achieved, and the service life of the cylinder is prolonged.

Synchronous pulley fixing shafts 24 are respectively fixed on two sides of the top of the cylinder back plate 22, each synchronous pulley fixing shaft 24 is provided with a synchronous pulley 23, and the synchronous pulleys 23 move up and down under the action of the rodless cylinder 21. The upper end and the lower end of the two first guide rail fixing profiles 29 are respectively and fixedly provided with an upper fixing plate 25 and a lower fixing plate 26, the upper fixing plate 25 and the lower fixing plate 26 are respectively connected and fixed with an upper aluminum profile edge and a lower aluminum profile edge on one side surface of the peripheral protective frame 1, the rodless cylinder power module 2 is fixedly connected with the peripheral protective frame 1 through the upper fixing plate 25 and the lower fixing plate 26, and the side surface and the first synchronous belt fixing plate 12 are positioned on the same side surface of the peripheral protective frame 1.

Referring to fig. 4, the lifting module 3 is mainly used in the conveying field, so that one section of electric conveying line is fixed on the lifting module 3, and the lifting module is a conveying line lifting module. It includes transfer chain 31, transfer chain mount 32, promotes backplate 33, second hold-in range fixed plate 34, second guide rail 35, second slider 36, second guide rail fixed profile 37 and hold-in range 38.

The two second rail fixing profiles 37 can increase the rigidity of the second rail 35, and can be conveniently connected with the peripheral protective frame 1 through the T-shaped groove of the second rail fixing profile 37.

The rodless cylinder power module and the conveying line lifting module can move up and down independently and cannot interfere with each other. And in order to realize the utility model discloses a double stroke effect, we connect fixed and fixed connection in aluminium alloy protecting frame 1 with hold-in range 38 one end in first hold-in range fixed plate 12, fixed second hold-in range fixed plate 34 is connected to the other end to connect fixed promotion backplate 33 through it, the hold-in range is hung and is located on synchronous pulley 23 at last.
