[0036] In this embodiment, Figure 2 and Figure 3 are respectively the perspective view and side view of the lifting assembly 200, the transmission assembly 100 is used as a component for horizontal transmission, and the whole is also a platform for placing goods; the first driving device 220 is used to drive the first chain 230 to rotate, and a structure combined with a motor and a rotating wheel can be selected, the first chain 230 is wound around the rotating wheel and driven by the motor; the first sprocket 240 is a driven wheel, and the number can be selected according to the actual situation; the number of the first chain 230 is not limited, as long as it can meet the stable transmission.

[0037] As shown in Figure 2 and Figure 3 , the number of the first chain 230 in this embodiment is 4, and the number of the first sprocket 240 is 6, which is divided into two groups; four first sprockets 240 are arranged on the cross beam 213 of the lifting frame 210, and the other two are arranged below the bottom plate 211 of the lifting frame 210, and two first chains 230 are arranged on each first sprocket 240, and the lifting assembly 200 drives the transmission assembly 100 to move upward through chain transmission. The transmission assembly 100 is provided with a chain hoist 170, and both ends of the first chain 230 are connected to the chain hoist 170. Under this arrangement, the lifting assembly 200 further comprises a driving shaft 250, and the first driving device 220 drives four first chains 230 through the driving shaft 250. In this embodiment, the first sprocket 240 is installed on the upper and lower sides of the lifting frame 210 respectively, so that the direction of the chain hanging down is perpendicular to the transmission assembly 100, the number of chains and sprockets is reduced, the size of the equipment is reduced, the chains on both sides are synchronously driven, and the stability of the chain transmission is ensured.

[0038] In an optimization scheme, as Figure 4The three-dimensional view of the hoisting frame shows a specific optimization of the structure of the hoisting frame 210. The hoisting frame 210 includes a base plate 211, a column 212, and a crossbeam 213. The first sprocket 240 is mounted on the base plate 211 and the crossbeam 213. The first chain 230 passes through the interior of the column 212 and is arranged around the first sprocket 240. The hoisting frame 210 also includes a chain guard 214, a mounting groove 215, and a protective plate 216. The chain guard 214 is mounted on the crossbeam 213 and covers the first sprocket 240. The first drive device 220 is disposed within the mounting groove 215, and the protective plate 216 covers the mounting groove 215. A buffer 260 is provided at the bottom of the crossbeam 213.

[0039] In this optimization scheme, such as Figure 1 , 2 As shown in Figure 4, a transmission assembly 100 is provided between the lifting frames 210. The first sprocket 240 is mounted on the base plate 211 and the crossbeam 213 to facilitate the hanging of the first chain 230. The first chain 230 passes through the interior of the column 212, which serves to protect the chain. It is understood that the column 212 is vertically mounted. To ensure stable transmission of the chain within the column 212, a guide sprocket can be installed at an appropriate position to prevent motion interference. To further protect the first chain 230, a protective cover needs to be installed on the crossbeam 213. Since the base plate 211 is semi-enclosed and the first sprocket 240 is located at the bottom of the base plate 211, a protective cover is not required. The mounting slot 215 is used to house the first drive device 220, and the protective plate 216 protects the first chain 230 mounted on the first drive device 220. A buffer 260 is provided at the bottom of the crossbeam 213. The buffer 260 can be made of some elastic materials or structures, such as spring components and rubber, which are not specifically limited here. The buffer 260 can prevent the transmission component 100 or the goods on the transmission component 100 from directly hitting the crossbeam 213, absorb the impact force during the lifting process, and play a role in protecting the equipment and extending the service life of the equipment.

[0040] In one optimization scheme, the lifting component 200 and the transmission component 100 are specifically optimized. The transmission component 100 and the lifting component 200 are made of aluminum.

The transmission frame 110 is provided with three rows of drums, the drums on the two sides are the transmission drums 150 driven by the second driving device 120; the drums in the middle row are driven drums. This device can not be provided with the driven drums, or can be provided with multiple rows of driven drums, and the specific number depends on the width of the transmission frame 110 and the need for transmission of goods. Adjacent two transmission drums 150 are connected through the second sprocket 140 and the second chain 130, and two transmission drums 150 in the transmission frame 110 are connected through a transmission shaft and the second chain 130. It can be understood that the use of only one row of transmission drums 150 can also achieve material transmission, and the setting of two rows or more can improve the stability of transmission.

[0044] In an optimization scheme, the transmission assembly 100 is particularly optimized. The transmission assembly 100 is provided with a plurality of guide wheels 160 abutting against the uprights 212 of the lifting frame 210.

This setting can improve the stability of the lifting assembly 200 lifting the transmission assembly 100.

[0046] In an optimization scheme, as shown in Figure 1 The transmission assembly 100 is particularly optimized. The transmission assembly 100 is provided with an optical-electric assembly 400 for distance measurement.

[0047] In the optimization scheme, the ranging principle of the photoelectric assembly 400 mainly depends on the emission and reception of light, and the distance is determined by analyzing the reflection of light on the target object.

The arrangement positions of these components can be determined according to the specific structure, and the embodiment is not limited. The photoelectric assembly 400 in the embodiment functions to monitor the position of the goods in real time. In addition, the scheme further provides a travel switch assembly, which cooperates with the photoelectric assembly 400 to ensure accurate control of the state of the goods during the transmission.

[0048] In one optimization scheme, the chain elevator in the logistics industry is optimized. The chain elevator in the logistics industry further comprises a slope assembly 300 arranged at the feeding end and / or the discharging end of the transmission assembly 100.

[0049] In the optimization scheme, the slope assembly 300 is arranged at the feeding end and / or the discharging end of the transmission assembly 100, which is used to assist feeding and discharging and improve the convenience of goods transportation.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily.
