[0025] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0026] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0028] The embodiment of the utility model provides a stacker equipped with a chain and a wire rope, such as Figure 1-4As shown, it includes a frame 100, a cargo platform 200, a counterweight 400, a chain 510, a steel wire rope 520 and a lifting drive assembly 300. The cargo platform 200 and the counterweight 400 are both slidably connected to the frame 100 in the vertical direction. The cargo platform 200 is used to place goods or a pallet loaded with goods. When the stacker is working, the cargo platform 200 and the counterweight 400 move in opposite directions. The counterweight 400 can pull the cargo platform 200, so that the lifting drive assembly 300 can use a smaller driving force to lift the cargo platform 200, reducing the driving force requirement for the lifting drive assembly 300. Both ends of the chain 510 and the steel wire rope 520 are respectively connected to the cargo platform 200 and the counterweight 400. Specifically, both ends of the chain 510 are respectively connected to the cargo platform 200 and the counterweight 400, and both ends of the steel wire rope 520 are also respectively connected to the cargo platform 200 and the counterweight 400. The chain 510 and the steel wire rope 520 can jointly pull the cargo platform 200. The lifting drive assembly 300 is used to drive the chain 510 and the steel wire rope 520 to move synchronously, and then synchronously transmit the driving force through the chain 510 and the steel wire rope 520, thereby driving the cargo platform 200 to move in the vertical direction, so as to achieve the rise and fall of the cargo platform 200.

[0029] In this embodiment, if the chain 510 breaks, the lifting drive assembly 300 can still drive the cargo platform 200 to rise and fall through the steel wire rope 520, thereby preventing the cargo platform 200 from falling, which improves the safety of the stacker. At the same time, the chain 510 and the steel wire rope 520 can share the gravity, reducing the force on the chain 510, so that the chain 510 is not easy to break, thereby extending the service life of the entire stacker.

[0030] In some embodiments, the lifting drive assembly 300 includes a drive shaft 320 rotatably connected to the frame 100, a lifting drive mechanism 310 connected to the drive shaft 320 and used to drive the drive shaft 320 to rotate, a main gear 330 sleeved on the drive shaft 320, and a main drive wheel 340 sleeved on the drive shaft 320, the chain 510 is meshed with the main gear 330, and the wire rope 520 is wound around the main drive wheel 340. When the lifting drive mechanism 310 drives the drive shaft 320 to rotate, it drives the main gear 330 and the main drive wheel 340 to rotate accordingly, the main gear 330 then drives the chain 510 to move, and the main drive wheel 340 then drives the wire rope 520 to move, thereby pulling the cargo platform 200.

[0031] In this embodiment, the chain 510 and the wire rope 520 transmit the driving force from the same drive shaft 320, which can reduce the driving components and simplify the driving structure. The chain 510 and the wire rope 520 can move more synchronously, so that they can be subjected to force at the same time to pull the cargo platform 200 at the same time.

[0032] Further, the lifting drive assembly 300 also includes a driven shaft 350 rotatably connected to the frame 100, a slave gear 360 sleeved on the driven shaft 350, and a slave drive wheel 370 sleeved on the driven shaft 350. The chain 510 is also meshed with the slave gear 360, and the wire rope 520 is also wound on the slave drive wheel 370. The slave gear 360 provides support for the chain 510, which can extend the lateral length of the chain 510 and change the direction of the chain 510 so that the two ends of the chain 510 are respectively connected to the cargo platform 200 and the counterweight 400. Similarly, the slave drive wheel 370 provides support for the wire rope 520, which can extend the lateral length of the wire rope 520 and change the direction of the wire rope 520 so that the two ends of the wire rope 520 are respectively connected to the cargo platform 200 and the counterweight 400.

[0033] In some embodiments, the lifting drive mechanism 310 may include a motor 311 and a reducer 312 connected to the motor 311 .

[0034] In some embodiments, a wire rope limiting mechanism 600 is provided on the outer side of the main driving wheel 340 for limiting the wire rope 520 from detaching from the main driving wheel 340, so that the wire rope 520 can remain wound on the main driving wheel 340, thereby preventing the wire rope 520 from being dislocated.

[0035] Furthermore, a wire rope limiting mechanism 600 for limiting the wire rope 520 from being separated from the driving wheel 370 may also be provided from the outside of the driving wheel 370 , which has a better limiting effect on the wire rope 520 and ensures the driving force of the wire rope 520 .

[0036] Furthermore, the circumference of the main driving wheel 340 is provided with an annular groove, the steel wire rope 520 is wound in the annular groove, and the inner wall of the annular groove can limit the axial movement of the steel wire rope 520 relative to the main driving wheel 340 along the main driving wheel 340. The steel wire rope limiting mechanism 600 includes a limiting bracket 610 fixed on the frame 100 and a limiting top plate 620 connected to the limiting bracket 610. The limiting top plate 620 is located above the main driving wheel 340 and close to the annular groove, so that the steel wire rope 520 is not easy to move out of the annular groove, and the steel wire rope 520 is limited from being separated from the main driving wheel 340.

[0037] In some embodiments, two steel wire ropes 520 are provided, one end of each of the two steel wire ropes 520 is connected to the counterweight 400, and the other ends of each of the two steel wire ropes 520 are respectively connected to the two sides of the cargo platform 200; two groups of chains 510 are provided, one end of each of the two groups of chains 510 is connected to the counterweight 400, and the other ends of each of the two groups of chains 510 are respectively connected to the two sides of the cargo platform 200. In this way, the chains 510 and the steel wire ropes 520 both pull the cargo platform 200 from both sides of the cargo platform 200, so that the cargo platform 200 is evenly stressed, so that the cargo platform 200 can be pulled smoothly to prevent the cargo platform 200 from tilting.

[0038] In some embodiments, a connecting bracket 410 is provided on the top of the counterweight block 400, and the chain 510 and the steel wire rope 520 are fixedly connected to the connecting bracket 410 instead of being directly connected to the counterweight block 400. The connecting bracket 410 provides more installation space to facilitate the fixing of the chain 510 and the steel wire rope 520.

[0039] Furthermore, the connecting bracket 410 includes two connecting vertical plates 411 and a connecting horizontal plate 412 disposed between and connected to the two connecting vertical plates 411. The connecting vertical plates 411 can extend in the vertical direction, and the connecting horizontal plate 412 can extend in the horizontal direction. The chain 510 is fixedly connected to the connecting horizontal plate 412, and the steel wire rope 520 is fixedly connected to the connecting vertical plates 411.
