Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a drag chain anti-sway structure suitable for ultra-high stacker cranes. Background Technology

[0002] Currently, in automated intelligent warehouses, stacker cranes need to be connected to cables to supply power when storing and retrieving goods. To ensure the stability of equipment operation, vertical cable chains are needed to centrally fix the cables and prevent the stacker crane from swinging erratically during operation.

[0003] There are generally two methods for fixing cable chains in existing stacker cranes: one is a unidirectional cable chain fixing groove, suitable for stacker cranes with low height and short cable chain stroke; the other is a bidirectional cable chain fixing groove, suitable for stacker cranes with high height and long cable chain stroke. For ultra-high stacker cranes, the entire long-stroke cable chain guide groove is prone to interference with the cable chain during actual operation due to processing and installation errors, frequently leading to cable chain damage. Furthermore, the cable chain fixing groove is usually made of structural steel; when the cable chain swings, it collides with the guide groove, and the collision between the plastic cable chain and the steel guide groove can also cause damage and deformation to the cable chain. For ultra-high stacker cranes tens of meters high, the swing amplitude of the cable chain is even more violent, and the impact force between the cable chain and the guide groove is greater. Prolonged impact during operation can easily damage the cable chain, significantly reducing its service life. Preventing cable chain swaying has always been a challenge for ultra-high stacker cranes.

[0029] like Figure 3 and Figure 4 As shown, the first drag chain guide groove 600 includes two first guide groove plates 610 arranged symmetrically on the left and right. The first guide groove plate 610 has an L-shaped structure. The drag chain is located between the two first guide groove plates 610 and is limited by the two inner end faces of the first guide groove plates 610.

[0030] like Figure 5 and Figure 6 As shown, the second drag chain guide groove 700 includes two second guide groove plates 710 arranged symmetrically on the left and right. The second guide groove plate 710 has an L-shaped structure. The drag chain is located between the two second guide groove plates 710 and is limited by the two inner end faces of the second guide groove plates 710.

[0031] like Figure 3 and Figure 4 As shown, the first cable chain guide groove connecting assembly 100 includes a first mounting plate 110. The fixed end of the first mounting plate 110 is detachably connected to the side of the column 500 by multiple bolts. The adjustable end of the first mounting plate 110 is detachably connected to the back of the first guide bracket 120 by multiple bolts. A long, narrow first adjusting hole 130 is provided on the adjusting end of the first mounting plate 110 at the position corresponding to the connecting bolt. The bolts are connected in the first adjusting hole 130. The first adjusting hole 130 allows the first guide bracket 120 to adjust its distance relative to the column 500. The front of the first guide bracket 120 is provided with a vertically penetrating first passage groove 160, through which the moving end of the cable chain can move vertically through the first guide bracket 120.

[0032] like Figure 3 and Figure 4 As shown, a first guide plate 610 is detachably connected to the left and right sides of the front of the first guide bracket 120 via bolts. Elongated second adjustment holes 140 are provided on the left and right sides of the front of the first guide bracket 120 at the positions corresponding to the connecting bolts. The bolts are connected to the second adjustment holes 140, allowing the first guide plate 610 to be adjusted in height relative to the first guide bracket 120. First guide ramps 150 are provided on the upper and lower ends of the first guide bracket 120, inclined from the inside out, to guide the cable chain into the first guide bracket 120. In use, the front and rear ends of the moving end of the cable chain are limited by the back of the first guide bracket 120 and the first guide plate 610, respectively, while the left and right ends of the moving end of the cable chain are limited by the side faces of the first guide bracket 120 and the first guide plate 610, respectively.

[0033] like Figure 5 and Figure 6 As shown, the second cable chain guide groove connecting assembly 200 includes a second mounting plate 210.

The fourth adjustment hole 240 allows the first guide groove plate 610 and the second guide groove plate 710 to be adjusted in height relative to the second guide bracket 220.

[0034] like Figure 5 and Figure 6As shown, the distance between the front ends of the two second guide brackets 220 is smaller than the distance between the back ends of the two second guide brackets 220. The smaller distance between the front ends of the two second guide brackets 220 can limit the swinging of the cable chain, while the larger distance between the back ends of the two second guide brackets 220 can ensure the smooth operation of the moving end of the cable chain.

[0035] like Figure 5 and Figure 6 As shown, second guide plates 250 are distributed at the upper and lower ends of the second guide bracket 220. The second guide plates 250 are inclined from the inside to the outside and guide the cable chain into the second guide bracket 220.

[0036] like Figure 1 and Figure 2 As shown, the cable chain fixed end connecting assembly 300 is connected to the cable chain fixed end at one end and detachably connected to the side of the column 500 at the other end, and is located directly above the second cable chain guide groove 700. The cable chain moving end connecting assembly 400 is connected to the cable chain at one end and to a movable loading platform at the other end, and is located in the first cable chain guide groove 600. Driven by the loading platform, the cable chain moving end connecting assembly 400 can move up and down along the first cable chain guide groove 600.

[0037] like Figure 7 As shown, the cable chain fixed end connection assembly 300 includes a first cable chain fixing plate 310, which is detachably connected to the side of the column 500 by multiple bolts. A first cable chain mounting plate 320 is welded to the first cable chain fixing plate 310, and the first cable chain mounting plate 320 is detachably connected to the fixed end of the cable chain by multiple bolts. A long, narrow first cable chain adjustment hole 330 is provided on the first cable chain mounting plate 320 corresponding to the position of the connecting bolts. A bolt is installed in the first cable chain adjustment hole 330, allowing adjustment of the fixed position of the cable chain fixed end.

[0038] like Figure 8 As shown, the cable chain moving end connecting assembly 400 includes a second cable chain fixing plate 410, which is detachably connected to the side of the column 500 by multiple bolts. A second cable chain mounting plate 420 is welded to the second cable chain fixing plate 410, and the moving end of the cable chain is detachably connected to the second cable chain mounting plate 420 by multiple bolts. A long, narrow second cable chain adjustment hole 430 is provided on the second cable chain mounting plate 420 corresponding to the position of the connecting bolts. A bolt is installed in the second cable chain adjustment hole 430, allowing adjustment of the fixed position of the moving end of the cable chain. The second cable chain mounting plate 420 has an H-shaped structure and can move up and down between two first guide slot plates 610.

[0039] This invention fixes one end of the cable chain to the cable chain fixed end connecting assembly 300, which is fixed to the column 500 of the stacker crane. The other end of the cable chain is fixed to the cable chain moving end connecting assembly 400, which is fixed to a loading platform that can move vertically. Two second guide brackets 220 of the second cable chain guide groove connecting assembly 200 are symmetrically installed, allowing adjustment of the width gap between the cable chain and the connecting assembly. The second cable chain guide groove connecting assembly 200 is located in the lower half of the cable chain's movement, and its two second guide brackets 220 are non-equidistant bent parts in the width direction. The first guide bracket 120 of the first cable chain guide groove connecting assembly 100 is an integral equidistant bent part in the width direction, and the first cable chain guide groove connecting assembly 100 is located in the upper half of the cable chain's movement. The distance between the front ends of the two second guide brackets 220 of the second cable chain guide groove connecting assembly 200 is smaller than the distance between the back ends of the two second guide brackets 220. The smaller distance between the front ends of the two second guide brackets 220 can limit the swinging of the cable chain, while the larger distance between the back ends of the two second guide brackets 220 can ensure the smooth operation of the moving end of the cable chain. The first cable chain guide groove connecting assembly 100 is arranged in the upper part of the cable chain. Because the cable chain operates in a unidirectional manner in the upper part, it does not fold, and the swinging amplitude is much smaller than that in the lower part. Therefore, it is designed in a fixed form to increase the running accuracy. The first cable chain guide groove 600 and the second cable chain guide groove 700 are made of nylon, which is soft and can greatly reduce the impact damage to the cable chain during operation and extend its service life. The cable chain moving end connection component 400 has an insert structure. Driven by the loading platform, it moves vertically along the gap formed between the two first guide slot plates 610. This movement method can avoid the possibility of direct collision between the cable chain and traditional connecting parts during operation, and can effectively prevent damage to the cable chain during operation.
