[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model proposes a single-column 100 wire rope 110 stacker crane, mainly composed of a column 100, a wire rope 110, a loading platform 200, and a fall arrest mechanism. The column 100 serves as the supporting structure for the entire stacker crane and is vertically installed inside the warehouse. The wire rope 110 is located on the outside of the column 100, with one end fixed to the top of the column 100 or other suitable location, and the other end passing through a pulley system on the loading platform 200 and connecting to a drive unit. The forward and reverse rotation of the drive unit retracts and extends the wire rope 110, thereby driving the loading platform 200 to rise and fall along the column 100, completing the storage and retrieval operations of goods.

[0025] The anti-fall mechanism is a key safety component of the stacker crane of this utility model. It is mounted on a specially designed brake guide rail 120 on the column 100. The anti-fall mechanism mainly consists of a drive swing arm 320 and a brake block 330. The drive swing arm 320 has a fixed end and a movable end. The fixed end is fixed to a suitable position on the loading platform 200 by a connecting piece 210 such as a pin, allowing it to swing around the fixed end; the movable end is connected to the brake block 330. A certain braking gap is reserved between the brake block 330 and the brake guide rail 120. Under normal working conditions, the brake block 330 does not contact the brake guide rail 120, and the loading platform 200 can be raised and lowered smoothly. A brake cable 310 is also provided on the loading platform 200. One end of the brake cable 310 is fixed to the fixed structure of the loading platform 200, and the other end is connected to the movable end of the drive swing arm 320. When the stacker crane is running normally, the brake cable 310 is in a relatively slack state and has no tension on the drive swing arm 320. The drive swing arm 320 remains stationary, and the brake block 330 and the brake guide rail 120 maintain a braking gap, allowing the loading platform 200 to rise and fall freely.

[0026] Understandably, in the event of a stall and sudden fall of the loading platform 200, the brake cable 310 will be rapidly tightened due to the accelerated descent. The tightened brake cable 310 applies a tension force to the movable end of the drive lever 320, causing it to swing around its fixed end. As the drive lever 320 swings, its movable end drives the brake block 330 towards the brake guide rail 120. Due to the small braking gap between the brake block 330 and the brake guide rail 120, the brake block 330 will quickly press against the brake guide rail 120 under the drive of the drive lever 320. The friction between the brake block 330 and the brake guide rail 120 will rapidly increase, forming a powerful braking force. This braking force effectively prevents the loading platform 200 from continuing to fall, thus ensuring the safety of the loading platform 200 and the cargo, and avoiding serious accidents that could have been caused by the loading platform 200 falling.

[0027] It should be noted that placing the wire rope 110 on the outside of the column 100 has several significant advantages. From a manufacturing and installation perspective, this arrangement greatly simplifies the internal structure of the column 100, making its processing and manufacturing easier and reducing production costs. Simultaneously, when installing the wire rope 110, complex operations are unnecessary inside the column 100; installers can conveniently fix, tension, and adjust the wire rope 110 from the outside, improving installation efficiency. From a maintenance perspective, when the wire rope 110 needs replacement due to wear, breakage, or other malfunctions, operators can perform the replacement directly from the outside of the column 100 without disassembling the column 100 or other complex structures, significantly shortening maintenance time, reducing the impact of equipment maintenance on normal warehouse operations, and improving the overall operational efficiency of the warehouse.

[0028] The single-column 100 structural design results in a small footprint for the stacker crane, allowing for flexible deployment in limited spaces. Simultaneously, the rational component layout and compact structural design maximize warehouse space utilization and increase storage capacity while ensuring performance. By placing the wire rope 110 on the outside of the column 100, the internal structure of the column 100 is simplified, reducing manufacturing and installation difficulties. Furthermore, in the event of a fault in the wire rope 110, repair and replacement can be carried out quickly and easily, significantly reducing equipment downtime, improving warehouse operational efficiency, and lowering maintenance costs. The anti-fall mechanism has a simple structure and rapid response. In the instant the loading platform 200 stalls and falls, the brake cable 310 immediately pulls the drive lever 320, causing the drive brake block 330 to quickly engage with the brake guide rail 120, generating strong braking force and effectively preventing the loading platform 200 from falling. This provides reliable safety for goods and equipment, greatly improving the operational safety of the stacker crane.

[0029] Reference Figure 5 In some embodiments, the fall arrestor assembly includes a single brake block 330. When the fall arrestor assembly comprises only one brake block 330, this brake block 330 is mounted on one side of the brake guide rail 120. During the normal lifting and lowering of the loading platform 200, a certain braking gap is maintained between the brake block 330 and the brake guide rail 120 to ensure smooth movement of the loading platform 200. When the loading platform 200 stalls and falls, the brake cable 310 pulls the drive lever 320, which in turn moves the brake block 330 toward the brake guide rail 120 until the brake block 330 is in close contact with the brake guide rail 120, generating friction to prevent the loading platform 200 from continuing to fall. The single brake block 330 has a relatively simple structure and low cost, making it suitable for scenarios where the braking force requirement is not particularly high and the loading platform 200 has a relatively small load. Furthermore, it is relatively easy to install and maintain, and occupies little space.

[0030] In other embodiments, the anti-fall assembly includes two brake blocks 330, which are respectively mounted on both sides of the brake guide rail 120. The drive lever 320 is designed to act on both brake blocks 330 simultaneously; for example, the drive lever 320 is Y-shaped, with its two branches connecting to the two brake blocks 330 respectively. When the loading platform 200 stalls and falls, the brake cable 310 pulls the drive lever 320, which simultaneously moves the brake blocks 330 on both sides towards the brake guide rail 120, so that both brake blocks 330 are simultaneously in close contact with the brake guide rail 120, increasing the braking area and braking force. The simultaneous contact of the brake blocks 330 on both sides with the brake guide rail 120 greatly increases the braking area, thereby improving the braking force and making the braking effect more reliable. This is especially suitable for occasions where the loading platform 200 has a large load and high safety requirements, effectively preventing the loading platform 200 from falling and ensuring the safety of goods and equipment.

[0031] It should be noted that in the embodiment with dual-sided brake blocks 330, the anti-fall assembly includes two brake blocks 330 and two drive swing arms 320, with both ends of the brake cable 310 connected to the movable ends of the two drive swing arms 320 respectively. When the loading platform 200 stalls and falls, the brake cable 310 simultaneously pulls the two drive swing arms 320, causing them to swing synchronously. This, in turn, drives the two brake blocks 330 to move towards and engage with the brake guide rail 120, achieving synchronous braking on both sides. By simultaneously driving the two drive swing arms 320 with the brake cable 310, the synchronicity of the movement of the two brake blocks 330 can be ensured, making the braking on both sides more uniform and improving the stability and reliability of the braking. Moreover, this structural layout is reasonable and easy to install and debug.

[0032] On the other hand, the fall arrestor assembly has two brake blocks 330, which are connected by a linkage, such as a connecting rod or chain. A drive lever 320 connects to and drives one of the brake blocks 330 to move. When this brake block 330 moves, it drives the other brake block 330 to move synchronously via the linkage. For example, a connecting rod can be used, with one end hinged to one brake block 330 and the other end hinged to the other. When the drive lever 320 pushes one brake block 330, the connecting rod transmits the motion to the other brake block 330, causing both brake blocks 330 to simultaneously engage with the brake guide rail 120. Using a linkage to achieve synchronous movement of the two brake blocks 330 results in a simple structure and low cost. Furthermore, the linkage can be flexibly designed and installed according to actual conditions, adapting to different space and structural requirements, and can effectively transmit motion, ensuring that both brake blocks 330 can simultaneously engage with the brake guide rail 120 for braking.

[0033] Reference Figure 3 and Figure 4Furthermore, a contact rod 340 is connected to the movable end of the drive lever 320, and a drive protrusion 341 is provided on the contact rod 340. An elongated drive groove 331 is provided on the brake block 330, and the drive groove 331 is inclined towards the side facing the brake guide rail 120. The drive protrusion 341 abuts against the groove wall of the drive groove 331. When the loading platform 200 is normally raised and lowered, the drive protrusion 341 is relatively stationary in the drive groove 331, and the brake block 330 maintains a braking gap with the brake guide rail 120. When the loading platform 200 stalls and falls, the brake cable 310 pulls the drive lever 320, which drives the contact rod 340 to rotate. The drive protrusion 341 moves in the drive groove 331. Because the drive groove 331 is inclined, the drive protrusion 341 pushes the brake block 330 towards the brake guide rail 120 until the brake block 330 is in close contact with the brake guide rail 120 to achieve braking. When the loading platform 200 returns to normal, the drive lever 320 swings in the opposite direction, and the drive protrusion 341 moves in the opposite direction within the drive groove 331, causing the brake block 330 to move away from the brake guide rail 120, restoring the braking clearance. This structure, through the cooperation of the drive protrusion 341 and the inclined drive groove 331, can convert the swing motion of the drive lever 320 into the linear movement of the brake block 330, achieving a clever conversion of motion. Furthermore, the inclined drive groove 331 allows the brake block 330 to achieve a larger movement distance with a smaller swing angle, improving the braking response speed and effect. At the same time, this structure is simple, reliable, and easy to manufacture and maintain.

[0034] Reference Figure 3 and Figure 4 A first fixing rope member 250 is installed on the loading platform 200, and a second fixing rope member 311 is installed on the drive swing arm 320. The two ends of the brake cable 310 are connected to the first fixing rope member 250 and the second fixing rope member 311 respectively. By adjusting the positions of the first fixing rope member 250 and the second fixing rope member 311, the brake cable 310 is kept taut. It is also ensured that the vertical height of the first fixing rope member 250 is greater than that of the second fixing rope member 311, creating a height difference. When the loading platform 200 stalls and falls, due to the height difference, the brake cable 310 can pull the drive swing arm 320 more quickly, causing the drive swing arm 320 to swing rapidly, driving the brake block 330 to press tightly against the brake guide rail 120 to achieve braking. It should be noted that the height difference design between the first fixing rope component 250 and the second fixing rope component 311 allows the braking cable 310 to generate an additional tensile force component when the loading platform 200 stalls and falls, accelerating the swing speed of the drive swing arm 320 and thus improving the response speed of the anti-fall mechanism. This allows for rapid braking triggered the instant the loading platform 200 begins to fall, effectively shortening the braking distance and significantly improving the safety of the loading platform 200. Furthermore, this structure is simple, easy to adjust, and the height difference can be flexibly set according to actual conditions.

[0035] Reference Figure 4 In some embodiments, the anti-fall assembly includes a reset element 321, such as a spring or torsion spring. One end of the reset element 321 is connected to the movable end of the drive swing arm 320, and the other end is connected to the fixed structure of the loading platform 200. When the loading platform 200 falls normally, the reset element 321 is in its natural state or has a certain preload. Its elastic force acts on the drive swing arm 320, preventing it from swaying due to minor external disturbances and ensuring a stable braking gap between the brake block 330 and the brake guide rail 120, allowing the loading platform 200 to rise and fall normally. When the loading platform 200 stalls and falls, the tension of the brake cable 310 is greater than the elastic force of the reset element 321. The drive swing arm 320 overcomes the elastic force of the reset element 321 and swings, causing the brake block 330 to brake. After braking ends, the elastic force of the reset element 321 causes the drive swing arm 320 to return to its initial position, and the braking gap between the brake block 330 and the brake guide rail 120 is restored. The reset component 321 effectively prevents the drive lever 320 from malfunctioning due to external factors during the normal descent of the loading platform 200, thus improving the reliability and stability of the fall arrest mechanism. The braking force of the brake cable 310 only triggers braking when the loading platform 200 actually stalls and falls, reducing unnecessary braking operations and extending the service life of the fall arrest mechanism. Simultaneously, the reset component 321 automatically resets the drive lever 320 after braking, facilitating normal use next time.

[0036] Reference Figure 2 A connector 210 is installed on the loading platform 200, and the upper and lower ends of the wire rope 110 are respectively connected to the connector 210. For example, the connector 210 can be a metal plate with two rope holes, through which the upper and lower ends of the wire rope 110 are passed and fixed. When the wire rope 110 moves under the action of the drive device, it drives the loading platform 200 to rise and fall along the column 100 through the connector 210. If the wire rope 110 moves upward, the connector 210 is subjected to an upward pulling force, thereby driving the loading platform 200 to rise; if the wire rope 110 moves downward, the connector 210 is subjected to a downward pulling force, driving the loading platform 200 to fall. This connection method has a simple structure, direct transmission, and can efficiently transmit the movement of the wire rope 110 to the loading platform 200, realizing the raising and lowering of the loading platform 200. Furthermore, the design of connector 210 can be optimized according to actual conditions, improving the reliability and stability of the connection, reducing friction and wear between wire rope 110 and loading platform 200, and extending the service life of the equipment. At the same time, it facilitates installation and maintenance, reducing manufacturing costs.

[0037] Furthermore, a speed limiting buckle 220 is installed on one side of the connector 210, and the speed limiting cable 230 is threaded through the speed limiting buckle 220. Speed ​​limiting wheels 240 are installed at the upper and lower ends of the column 100, so that the speed limiting cable 230 forms a closed loop around these two speed limiting wheels 240. The speed limiting buckle 220 abuts against the speed limiting cable 230. When the loading platform 200 is raised and lowered normally, the speed limiting cable 230 moves smoothly on the speed limiting wheels 240. The friction between the speed limiting buckle 220 and the speed limiting cable 230 is small and does not affect the movement of the loading platform 200. When the loading platform 200 moves too fast, the friction between the speed limiting cable 230 and the speed limiting buckle 220 increases, and the speed limiting cable 230 generates a reverse pulling force on the speed limiting buckle 220. The speed limiting cable 230 limits the movement speed of the loading platform 200 through the connector 210, preventing the loading platform 200 from being dangerous due to excessive speed. The speed limiting buckle 220 and speed limiting cable 230 provide additional restrictions and protection on the lifting speed of the loading platform 200. In the event of a drive unit malfunction or other reasons causing an abnormal increase in the speed of the loading platform 200, the speed limiting mechanism can function promptly to limit the speed of the loading platform 200, preventing safety accidents caused by excessive speed. This speed limiting method has a simple structure, low cost, does not require an additional power source, has high reliability, and can effectively improve the safety performance of the stacker crane.

[0038] Reference Figure 1 The single-column 100-wire rope 110 stacker crane proposed in this utility model also includes a vehicle body 400, on which the column 100, wire rope 110, and loading platform 200 are mounted. A rail 410 is connected to the top of the vehicle body 400. Multiple left roller sets 420 and right roller sets 430 are arranged on the vehicle body 400, which horizontally clamp the rail 410. During the movement of the vehicle body 400, the left roller sets 420 and right roller sets 430 roll on the rail 410, guiding the vehicle body 400 to move stably along the direction of the rail 410, while preventing the vehicle body 400 from swaying horizontally, ensuring the smooth operation of the stacker crane. The cooperation of the upper rail 410 and the roller sets provides precise guidance for the vehicle body 400, enabling it to maintain stable linear motion during movement and improving the positioning accuracy of the stacker crane. At the same time, this structure can withstand the lateral force generated by the vehicle body 400 when lifting and lowering goods, which enhances the overall stability of the stacker crane and reduces damage to goods and equipment failure caused by shaking.

[0039] In other embodiments, a lower rail 410 is installed on the warehouse floor, and the bottom of the vehicle body 400 is equipped with wheels that cooperate with the lower rail 410. The vehicle body 400 moves on the lower rail 410 via the wheels, enabling the stacker crane to move horizontally within the warehouse to transport goods to different shelf locations. The upper rail 410 or the lower rail 410 can be installed alone, or both can be installed simultaneously, depending on the actual conditions and needs of the warehouse. The lower rail 410 provides stable support and guidance for the horizontal movement of the vehicle body 400, allowing it to move smoothly on the warehouse floor. By rationally designing the layout of the lower rail 410, efficient operation of the stacker crane within the warehouse can be achieved, improving the efficiency of goods storage and retrieval. Furthermore, the lower rail 410 has a simple structure, is easy to install and maintain, and has low cost.

[0040] This utility model also proposes a warehousing system, including a single-column 100-steel-rope 110 stacker crane as described in any of the preceding claims, as well as shelves, cargo storage units, etc. The single-column 100-steel-rope 110 stacker crane is installed in a suitable position within the warehousing system, enabling it to move between shelves and perform cargo storage and retrieval operations via a loading platform 200. Depending on the size and layout of the warehouse, multiple single-column 100-steel-rope 110 stacker cranes can be configured to improve the overall operational efficiency of the warehousing system. The warehousing system using the single-column 100-steel-rope 110 stacker crane of this utility model has advantages such as high efficiency, safety, and flexibility.
