Technical Field

[0001] This utility model relates to the technical field of stacker crane structures, and in particular to a chain-type single-column stacker crane. Background Technology

[0002] When materials need to be stacked, a stacker crane is required. The stacker crane can move horizontally and its loading platform can be raised and lowered, thus allowing materials to be stacked into piles.

[0003] The structure that drives the lifting and lowering of the loading platform can be a chain. The chain extends vertically, and the motor drives the chain to lift and lower through the sprocket. At the same time, the two ends of the chain are connected to and tensioned with the loading platform. Therefore, when the chain rises, the loading platform will rise synchronously, and when the chain descends, the loading platform will rise and fall synchronously.

[0004] However, when the chain breaks due to wear or overload, the loading platform may suddenly drop, creating a danger. Utility Model Content

[0031] The following describes a chain-type single-column stacker according to an embodiment of the present invention, with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 The present invention aims to provide an embodiment of a chain-type single-column stacker crane.

[0033] In this embodiment, the chain-driven single-column stacker crane mainly consists of a column 400, a loading platform 200, a chain 100, and an anti-fall mechanism. The column 400 serves as the supporting structure for the entire stacker crane, providing a stable track for the lifting and lowering of the loading platform 200. The chain 100 is fitted onto the outside of the column 400 and, in conjunction with the motor and sprocket, enables the lifting and lowering of the loading platform 200. The loading platform 200 is used to carry materials and is a key component for the stacker crane to achieve its material stacking function. The anti-fall mechanism is the core innovation of this invention, used to prevent the loading platform 200 from falling when the chain 100 breaks.

[0034] Specifically, the chain 100 has an upper connecting end 110 and a lower connecting end 120, both of which are connected to the loading platform 200 and keep the chain 100 taut. Specifically, the upper connecting end 110 includes an upper connecting rod, the top of which is connected to the chain 100. The bottom of the upper connecting rod has an upper limit stop, which can be a protruding structure for engaging with an upper mounting portion on the loading platform 200. The loading platform 200 has an upper mounting portion with an upper mounting hole for accommodating the upper connecting rod. After the upper connecting rod passes through the upper mounting hole, the upper mounting portion and the upper limit stop abut against each other vertically. When the chain 100 rises, because the upper connecting rod is connected to the chain 100, the upper connecting rod rises along with the chain 100. Simultaneously, the upper limit stop causes the upper mounting portion to rise, thereby causing the loading platform 200 to rise. This connection structure is simple and reliable, ensuring the synchronous movement of the loading platform 200 and the chain 100.

[0035] It should be noted that the anti-fall mechanism includes a swing arm 130, the rotation center of which is mounted on the upper connecting rod. The free end of the swing arm 130 is positioned close to the column 400 so that it can interact with the anti-fall blocks 300 on the column 400 when needed. Several anti-fall blocks 300 are arranged vertically on the column 400, and these blocks can be evenly distributed on one side of the column 400 to form an anti-fall blocking system. Under normal operating conditions, the swing arm 130 remains in a relatively stable position due to its own weight or the action of other limiting devices. At this time, the free end of the swing arm 130 does not contact the anti-fall blocks 300, and the loading platform 200 can rise and fall normally. When the chain 100 breaks due to wear or overload, the loading platform 200 loses the support of the chain 100 and begins to fall. Since the rotation center of the swing arm 130 is mounted on the upper connecting rod, the descent of the loading platform 200 will cause the upper connecting rod to descend along with it, while the free end of the swing arm 130 will deflect upward around the rotation center due to inertia. As the loading platform 200 continues to fall, the free end of the swing arm 130 will come into contact with a fall arrestor block 300 on the column 400. The fall arrestor block 300 acts as a stop for the free end of the swing arm 130, thereby preventing the loading platform 200 from falling further and effectively preventing the dangerous fall of the loading platform 200 due to the breakage of the chain 100.

[0036] In the material stacking process of a specific embodiment, the stacker crane, driven by a motor, raises or lowers the chain 100 via a sprocket, thereby raising or lowering the loading platform 200. When materials need to be placed at a designated height, the loading platform 200 carries the materials upwards. After reaching the target position, the loading platform 200 stops rising, completing the placement of the materials. During the long-term operation of the stacker crane, the chain 100 may gradually wear down. If the wear reaches a certain level, or if material overload occurs occasionally, the chain 100 may break. At this time, the anti-fall mechanism of this utility model will immediately come into play. The free end of the swing arm 130 abuts against the anti-fall block 300, preventing the loading platform 200 from falling and avoiding equipment damage and personal injury accidents caused by the falling loading platform 200.

[0037] Understandably, the chain-driven single-column stacker crane proposed in this utility model, by incorporating an anti-fall mechanism, can effectively prevent the loading platform 200 from falling when the chain 100 breaks, greatly reducing the risk of safety accidents caused by the falling loading platform 200 and ensuring the personal safety of operators and the normal operation of the equipment. Furthermore, the anti-fall mechanism has a simple and clear structural design, mainly composed of a swing arm 130 and an anti-fall block 300, making it easy to manufacture and install. Simultaneously, its working principle is based on simple mechanical motion, requiring no complex electrical control system, and possesses high reliability and stability. Moreover, due to the simple structure of the anti-fall mechanism, its maintenance and upkeep are relatively easy. During normal use, only periodic checks of the swing arm 130 and the anti-fall block 300 are needed to ensure their normal operation, without requiring significant maintenance costs.

[0038] Reference Figure 2 Furthermore, a side through-hole 211 is provided on the loading platform 200. The position and size of the side through-hole 211 are designed according to the shape and swing requirements of the swing arm 130. The swing arm 130 passes through the side through-hole 211, and the inner wall of the side through-hole 211 limits the swing range of the swing arm 130, ensuring that it can only swing within a reasonable range. When the chain 100 breaks, the loading platform 200 falls, causing the upper connecting rod to descend. When the swing arm 130 deflects upward around the rotation center, the top of the inner surface of the side through-hole 211 abuts against the swing arm 130, limiting the swing arm 130 and ensuring that the free end of the swing arm 130 remains in contact with the anti-fall block 300, thereby effectively preventing the loading platform 200 from continuing to fall. By limiting the swing range of the swing arm 130 through the side through-hole 211, it is ensured that when the chain 100 breaks, the swing arm 130 can accurately abut against the anti-fall block 300, improving the reliability and stability of the anti-fall mechanism.

[0039] The loading platform 200 comprises a loading platform body, a side mounting plate 210, an upper mounting plate 220, and a lower mounting plate 230. The side mounting plate 210 is connected to the loading platform body and its shape and dimensions are designed to form side through-holes 211 to achieve the function defined for the swing arm 130 in claim 2. The upper mounting plate 220 is also connected to the loading platform body and forms an upper mounting section. An upper mounting hole on the upper mounting section allows the upper connecting rod to pass through and cooperates with the upper limit section to drive the loading platform 200 upwards. The lower mounting plate 230 is also connected to the loading platform body and connects to the lower connecting end 120 of the chain 100, ensuring a reliable connection between the chain 100 and the loading platform 200 through a specific connection structure. Designing the loading platform 200 as a combination of multiple components facilitates manufacturing, installation, and maintenance. The clear division of labor among the components improves the overall performance and reliability of the loading platform 200.

[0040] In some embodiments, a lower mounting hole is provided on the lower mounting plate 230, and the lower connecting end 120 includes a lower connecting rod, a lower abutment sleeve 123, and a lower nut 122. The lower connecting rod is connected to the chain 100, the lower abutment sleeve 123 is fitted onto the lower connecting rod, and the lower nut 122 is threaded onto the lower connecting rod. The lower nut 122 and the lower abutment sleeve 123 are arranged vertically in sequence. During installation, the lower connecting rod is passed through the lower mounting hole, and the position of the lower nut 122 is adjusted so that the lower abutment sleeve 123 abuts against the lower mounting plate 230, thereby achieving a reliable connection between the lower connecting end 120 of the chain 100 and the loading platform 200. Through the cooperation of the lower abutment sleeve 123 and the lower nut 122, the lower connecting end 120 of the chain 100 can be tightly connected to the loading platform 200, ensuring that the chain 100 will not loosen or fall off when driving the loading platform 200 to rise and fall, thus improving the stability and safety of the stacker crane operation.

[0041] Specifically, the upper limit stop includes an upper nut 112 and an upper abutment sleeve 113. The upper nut 112 is threaded onto the upper connecting rod, and the upper abutment sleeve 113 is fitted onto the upper connecting rod and located on top of the upper nut 112. During installation, the position of the upper nut 112 is adjusted so that the upper abutment sleeve 113 abuts against the upper mounting part, thereby achieving the function of driving the lifting of the loading platform 200. The anti-fall mechanism includes an anti-fall sleeve 114, which is fitted onto the upper connecting rod and located between the upper nut 112 and the upper abutment sleeve 113. A rotating shaft is provided on the anti-fall sleeve 114, and the rotation center of the swing arm 130 is mounted on the rotating shaft, allowing the swing arm 130 to rotate around the rotating shaft. The upper limit stop and the anti-fall mechanism have a reasonable structural design, and the components fit tightly together, effectively achieving the functions of driving the lifting of the loading platform 200 and preventing falls.

[0042] Furthermore, a spring is provided between the upper abutment sleeve 113 and the upper mounting part, or between the upper abutment sleeve 113 and the anti-fall sleeve 114. When the chain 100 is working normally, the spring is in a compressed state. When the chain 100 breaks and the loading platform 200 falls, the spring expands, causing the anti-fall sleeve 114 to shift downward relative to the upper mounting part, thereby causing the free end of the swing arm 130 to quickly deflect and tilt upward, abutting against the anti-fall block 300 and preventing the loading platform 200 from falling. The spring design enables the anti-fall mechanism to respond quickly when the chain 100 breaks, rapidly preventing the loading platform 200 from falling, thus improving the working efficiency and reliability of the anti-fall mechanism.

[0043] In some embodiments, there are two pivots and two swing arms 130. The two swing arms 130 are located on both sides of the fall arrestor 114 and are connected to the fall arrestor 114 via pivots. The fall arrestor 114 includes a base plate with a through hole in the center to allow the upper connecting rod to pass through, and a pivot on the edge of the base plate for mounting the swing arms 130. The design of two swing arms 130 can improve the stability of the fall arrestor mechanism, make the loading platform 200 more evenly stressed during fall arrest, and prevent the loading platform 200 from tilting or swaying during fall arrest.

[0044] Furthermore, an angle is provided on the upper side of the free end of the swing arm 130, the angle of which is designed according to the shape and spacing of the anti-fall blocks 300. When the chain 100 lifts the loading platform 200, the angle can avoid the anti-fall blocks 300, allowing the loading platform 200 to rise smoothly. The angle reduces the friction between the swing arm 130 and the anti-fall blocks 300, making the loading platform 200 move more smoothly during normal lifting and lowering, thus improving the working efficiency of the stacker crane.

[0045] Reference Figure 3 It should be noted that the chain-type single-column stacker crane includes a vehicle body, on which a column 400, a chain 100, and a loading platform 200 are mounted. The top of the vehicle body is connected to an upper rail 500. A first support roller and a second support roller are mounted on the vehicle body, arranged along the extension direction of the upper rail 500, with their tops abutting against the upper rail 500, allowing the vehicle body to move stably along it. By setting up the upper rail 500 and the support rollers, the vehicle body is made more stable during movement, reducing swaying and deviation, and improving the operating accuracy and safety of the stacker crane.

[0046] The vehicle body is also equipped with a left-side roller assembly 510 and a right-side roller assembly 520, which horizontally clamp the upper rail 500, further enhancing the stability of the vehicle body on the upper rail 500. Alternatively, the chain-type single-column stacker crane also includes a lower rail, through which the vehicle body moves. By setting up the left-side roller assembly 510 and the right-side roller assembly 520, the stability of the vehicle body on the upper rail 500 is further improved, reducing swaying and deviation of the vehicle body during movement.
