Description

Technical Field

[0001] The utility model relates to the technical field of automated intelligent warehousing, in particular to an anti-sway device for a drag chain of an ultra-high stacker. Background Art

[0002] At present, in the field of automated intelligent storage warehouses, when stackers are storing and retrieving goods, cables need to be connected to power the stacker equipment. In order to ensure the stability of the equipment operation, vertical drag chains are required to centrally fix the cables to prevent the drag chain stacker from swinging randomly during operation.

[0003] There are generally two ways to fix drag chains in existing stackers: one is a one-way drag chain fixing groove, which is suitable for stackers with low height and short drag chain travel; the other is a two-way drag chain fixing groove, which is suitable for stackers with high height and long drag chain travel. However, it is difficult to ensure the straightness of the two-way drag chain fixing groove during processing and installation, and the connection between the guide grooves is easy to scratch the drag chain. The entire long-travel drag chain guide groove is easy to interfere with the drag chain due to processing and installation errors during the actual operation of the stacker, resulting in damage to the drag chain from time to time.

[0004] In addition, when the drag chain swings, it collides with the drag chain guide groove, which will also cause damage and deformation to the drag chain. For ultra-high stackers that are dozens of meters high, the swing amplitude of the drag chain is more violent, and the impact force between the drag chain and the guide groove will be greater. The drag chain is easily damaged after a long period of collision, and its service life is greatly reduced. Since the drag chain guide plate is installed when the stacker is assembled on site, for ultra-high stackers, dozens of drag chain guide grooves may be required for fixing. When fixing, the straightness of the drag chain splicing is difficult to ensure. The drag chain does not run smoothly in the guide groove and is prone to scratches, which affects the service life and stability of the drag chain.

[0005] Therefore, for ultra-high stackers, how to prevent the drag chain from swinging has always been a difficult problem. Utility Model Content

[0006] In view of the above shortcomings in the existing production technology, the applicant provides an anti-sway device for a drag chain of an ultra-high stacker, thereby solving the swing problem of the lifting drag chain of the ultra-high stacker during operation.

[0007] The technical scheme adopted by the utility model is as follows: an anti-sway device for a drag chain of an ultra-high stacker, comprising a first end plate and a second end plate arranged symmetrically, the first end plate and the second end plate being connected by a drag chain limiting rod, a guide pulley being further arranged between the first end plate and the second end plate, and a supporting member limiting pulley being arranged above the guide pulley; a first guide wheel assembly and a second guide wheel assembly are arranged vertically and in an interval arrangement on the outer side wall of the first end plate; a counterweight weight is arranged on the bottom surface between the first end plate and the second end plate, the first guide wheel assembly and the second guide wheel assembly both cooperate with the track and move vertically along the track; and also comprising: a supporting member, one end of the supporting member is first fixed to a fixed end bracket on a column, and the other end of the supporting member first detours along the supporting member limiting pulley and the guide pulley in turn, and then is fixed to a movable end bracket on one side of the cargo platform through a force sensor.

[0008] As a further improvement of the above technical solution:

[0009] Preferably, the track is mounted on the column in a vertical direction.

[0010] Preferably, the fixed end bracket is fixed on a column, and a drag chain is also installed on the fixed end bracket, and the other end of the drag chain passes through a drag chain limit rod and a guide pulley in sequence and is then fixed on the movable end bracket.

[0011] Preferably, the mobile end bracket is fixed on a cargo platform that moves in a vertical direction.

[0012] Preferably, the structure of the guide pulley is as follows: it includes a wheel body for allowing the drag chain to bypass, and a guide groove for the supporting member to bypass is arranged on the outer side wall of the wheel body.

[0013] Preferably, the wheel body is an "I"-shaped wheel structure, and the guide groove is an inwardly recessed snap-fit ​​groove structure.

[0014] Preferably, the structure of the supporting member is a wire rope structure, a synchronous belt structure or a chain structure.

[0015] Preferably, the structure of the track is: including vertical "C"-shaped track grooves symmetrically distributed on both sides, in which the arc surface of the second guide wheel assembly abuts against the middle track surface, and the arc surface of the first guide wheel assembly abuts against the track surfaces on both sides.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model has the advantages of compact structure and convenient operation. The device of the utility model limits the drag chain limit rod and the guide pulley so that the device as a whole moves with the drag chain throughout the whole process. Through the guidance limitation of the track, the swing of the drag chain can be controlled and twisting will not occur. For the ultra-high stacker, the problem that the prior art cannot solve the torsion of the drag chain is fundamentally solved, and the swing problem of the drag chain during operation of the ultra-high stacker is also solved.

[0018] The utility model also has the following advantages:

[0019] The utility model bypasses the supporting member through the supporting member limiting pulley and the guide groove of the guide pulley in sequence, so that the weight of the entire device is supported by the supporting member, the drag chain does not bear the weight, and the drag chain will not be damaged due to the high pressure of the device's own weight on the drag chain.
