Abstract
Description
Technical Field
[0001] This application relates to the field of logistics equipment technology, specifically to a stacker crane drum wire rope adjustment device. Background Technology
[0002] In automated warehousing and logistics systems, stacker cranes are the core equipment for performing goods storage and retrieval operations. They achieve efficient storage by moving a loading platform up and down between high-level racks. Precise positioning of the loading platform is crucial for safe and efficient goods storage and retrieval. This positioning is typically achieved by a motor-driven rotating drum, with the lifting height of the loading platform controlled by the raising and lowering of a steel cable wound around the drum. Therefore, the steel cable and its adjusting mechanism are indispensable components for the stable operation of the stacker crane.
[0003] However, during long-term operation under load and repeated expansion and contraction, steel wire ropes inevitably undergo plastic elongation. This elongation causes changes in the effective length of the wire rope on the drum, making it impossible for the loading platform to accurately reach the preset cargo layer height. Positioning inaccuracies not only affect operational efficiency but also frequently trigger equipment alarms or even shutdowns, becoming one of the main problems affecting the reliability of stacker cranes.
[0004] Therefore, this application proposes a stacker crane drum wire rope adjustment device, which can effectively adjust and compensate for the length of the wire rope that has become elongated due to stretching during operation, thereby restoring and ensuring the accurate positioning of the loading platform, reducing downtime due to malfunctions, shortening maintenance time, and improving equipment operating efficiency. Utility Model Content
[0005] The main objective of this application is to provide a stacker crane drum wire rope adjustment device, which aims to solve the technical problem of inaccurate positioning of the stacker crane loading platform caused by the plastic elongation of the wire rope.
[0006] To achieve the above objectives, this application provides the following technical solution: A stacker crane drum wire rope adjustment device includes: The fixing assembly includes a base mounted on the outer side wall of one axial end of a stacker crane drum, the base having a mounting hole whose axis is perpendicular to the radial direction of the stacker crane drum; The wire rope limiting assembly is provided with a limiting hole for the wire rope to pass through; An adjusting rod is operably inserted into the mounting hole at one end and connected to the wire rope limiting assembly at the other end. By operating the adjusting rod to extend into / out of the mounting hole, the wire rope limiting assembly can be moved closer to / away from the base, thereby changing the path length of the wire rope during operation.
[0007] As a further improvement of this application, the wire rope limiting assembly includes a connecting block fixedly sleeved on the end of the adjusting rod away from the base, a first clamping plate and a second clamping plate that are parallel to each other, and a first fixing bolt threaded through the first clamping plate and the second clamping plate; the first clamping plate is installed on the connecting block, and the opposite end faces of the first clamping plate and the second clamping plate are respectively provided with semi-circular grooves. By operating the first fixing bolt to screw in, the first clamping plate and the second clamping plate are driven to move towards each other, so that the two semi-circular grooves are joined together to form the limiting hole.
[0008] As a further improvement of this application, the mounting hole is a threaded hole, and the adjusting rod is a bolt adapted to the threaded hole. The adjusting rod is operated to rotate around its own axis so that the adjusting rod is screwed in or out relative to the base, thereby driving the wire rope limiting assembly to move closer to or away from the base.
[0009] As a further improvement of this application, the fixing assembly further includes a third clamping plate and a fourth clamping plate arranged parallel to the side wall of the base, and a second fixing bolt and a third fixing bolt threaded through the third clamping plate and the fourth clamping plate respectively; the third clamping plate and the fourth clamping plate are configured to clamp the inner and outer sides of the stacker roller wall, and by operating the second fixing bolt and the third fixing bolt to screw them in, their extended ends can be pressed against the inner and outer sides of the stacker roller wall, thereby fixing the base to the outer side wall of one axial end of the stacker roller.
[0010] As a further improvement of this application, the fourth clamping plate is provided with a protruding strip on the side adjacent to the third clamping plate. When the third clamping plate and the fourth clamping plate are clamped on the stacker roller wall, the protruding strip and the annular baffle at the end of the stacker roller form an axial limiting structure to prevent the base from detaching outward along the axial direction of the stacker roller.
[0011] The technical solution provided in this application may include the following beneficial effects: By operating the adjusting rod, the wire rope limiting component moves axially closer to or further away from the fixed base, directly changing the effective path length of the wire rope during operation. This provides precise length compensation for the wire rope that has undergone plastic elongation due to long-term use, quickly restoring the lifting and positioning accuracy of the loading platform and solving the positioning inaccuracy problem caused by wire rope elongation in the stacker crane. This adjustment method eliminates the need to disassemble the rollers or replace the wire rope, shortening maintenance time and reducing labor intensity. At the same time, by maintaining the effective working length of the wire rope transmission, it reduces the risk of equipment failure alarms and downtime, ensuring the continuous and efficient operation of the automated warehousing system.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0016] Figure 1 An embodiment of a stacker crane drum wire rope adjusting device of this application is shown; see [link to relevant documentation]. Figure 1 In this embodiment, the stacker crane drum wire rope adjustment device includes: a fixing component 1, a wire rope limiting component 2, and an adjusting rod 3.
[0017] Among them, see Figure 1The fixing component 1 includes a base 11 installed on the outer wall of one axial end of the stacker crane drum. The base 11 has a mounting hole 12, the axis of which is perpendicular to the radial direction of the stacker crane drum. The wire rope limiting component 2 has a limiting hole 21 for the wire rope to pass through. One end of the adjusting rod 3 is operably inserted into the mounting hole 12, and the other end is connected to the wire rope limiting component 2. By operating the adjusting rod 3 to extend into / out of the mounting hole 12, the wire rope limiting component 2 can be moved closer to / away from the base 11, thereby changing the path length of the wire rope during operation. This allows for precise length compensation for the wire rope that has undergone plastic elongation due to long-term use, quickly restoring the lifting and positioning accuracy of the loading platform and solving the problem of positioning inaccuracy caused by wire rope elongation in the stacker crane. This adjustment method does not require disassembling the drum or replacing the wire rope, shortening maintenance time and reducing labor intensity. At the same time, by maintaining the effective working length of the wire rope transmission, it reduces the risk of equipment failure alarms and downtime, ensuring the continuous and efficient operation of the automated warehousing system.
[0018] Further, see Figure 1 The wire rope limiting assembly 2 includes a connecting block 22 fixedly sleeved on the end of the adjusting rod 3 away from the base 11, a first clamping plate 23 and a second clamping plate 24 parallel to each other, and a first fixing bolt 25 threaded through the first clamping plate 23 and the second clamping plate 24. The first clamping plate 23 is installed on the connecting block 22. The opposite end faces of the first clamping plate 23 and the second clamping plate 24 are respectively provided with semi-circular grooves. By screwing in the first fixing bolt, the first clamping plate 23 and the second clamping plate 24 are driven to move towards each other, so that the two semi-circular grooves are joined together to form the limiting hole 21. The wire rope can be quickly clamped by tightening a single bolt. The limiting hole 21 formed by the semi-circular grooves fits tightly with the outer diameter of the wire rope, effectively preventing the wire rope from slipping or shifting during the adjustment process. At the same time, the rigid connection between the clamping plate and the adjusting rod 3 ensures the stable transmission of force during length adjustment, further improving the accuracy of positioning compensation and operational reliability.
[0019] Further, see Figure 1 The mounting hole 12 is a threaded hole, and the adjusting rod 3 is a bolt adapted to the threaded hole. Operating the adjusting rod 3 to rotate around its own axis allows it to screw in or out relative to the base 11, thereby moving the wire rope limiting assembly 2 closer to or further away from the base 11. This converts rotational operation into precise axial linear displacement. By controlling the number of rotations of the adjusting rod 3, minute adjustments to the wire rope path length can be achieved, significantly improving the accuracy of length compensation. Simultaneously, the self-locking characteristic of the threaded fit ensures a stable and reliable position after adjustment, preventing reset due to vibration during the operation of the cargo platform, further guaranteeing the long-term effectiveness of the positioning adjustment.
[0020] Further, see Figure 1The fixing assembly 1 further includes a third clamping plate 13 and a fourth clamping plate 14 arranged parallel to the side wall of the base 11, and a second fixing bolt 15 and a third fixing bolt 16 threaded through the third clamping plate 13 and the fourth clamping plate 14, respectively. The third clamping plate 13 and the fourth clamping plate 14 are configured to clamp the inner and outer sides of the stacker crane drum wall. By screwing in the second fixing bolt 15 and the third fixing bolt 16, their protruding ends can be pressed against the inner and outer sides of the stacker crane drum wall, thereby fixing the base 11 to the outer side wall of one axial end of the stacker crane drum. By applying force independently on both sides of the bolts, adaptive clamping is achieved to meet the difference in drum wall thickness, ensuring the installation stability of the base 11 under vibration conditions. At the same time, it can be quickly disassembled and assembled without welding or damaging the drum body, greatly simplifying the maintenance and replacement process of the adjustment device and significantly reducing downtime and modification costs.
[0021] Further, see Figure 1 The fourth clamping plate 14 has a protruding strip 17 on the side adjacent to the third clamping plate 13. When the third clamping plate 13 and the fourth clamping plate 14 are clamped to the wall of the stacker crane drum, the protruding strip 17 and the annular baffle at the end of the stacker crane drum form an axial limiting structure to prevent the base 11 from detaching outward along the axial direction of the stacker crane drum. The mechanical cooperation between the protruding strip 17 and the annular baffle of the drum forms a rigid axial constraint, completely eliminating the risk of accidental loosening of the base 11 due to vibration during high-frequency lifting operations of the stacker crane; combined with the bolt clamping structure, a double insurance is formed, which greatly enhances the fixation reliability of the device under long-term dynamic load and provides continuous guarantee for the wire rope length adjustment function.
[0022] For example, the working principle of the stacker crane drum wire rope adjustment device is as follows: When the stacker crane's wire rope undergoes plastic elongation due to prolonged use, causing misalignment of the loading platform, the operator first clamps and fixes the base 11 to the outer wall of the drum end using the third clamping plate 13, fourth clamping plate 14, second fixing screw 15, and third fixing bolt 16 of the fixing component 1. At this time, the protrusion 17 of the fourth clamping plate 14 forms an axial limit with the drum's annular baffle to prevent the device from loosening. Then, the end of the wire rope is inserted between the third and fourth clamping plates 14 of the limiting component, and the third fixing bolt 16 is tightened to move the two clamping plates toward each other, clamping the wire rope through the limiting hole 21 formed by their semi-circular grooves. Finally, the adjusting rod 3 (bolt) is rotated, and its engagement with the threaded hole of the base 11 drives the adjusting rod 3 to move axially, causing the wire rope limiting component 2 to move closer to or further away from the base 11, thereby precisely changing the working path length of the wire rope and compensating for the elongation. After adjustment, the threaded self-locking characteristic maintains the set position, ensuring that the loading platform restores accurate lifting and lowering positioning.
[0023] In this embodiment, the in-situ precise compensation of the working length of the wire rope is achieved through the synergistic effect of the threaded precision fine-tuning mechanism and the modular clamping assembly. This device is directly installed at the end of the drum, using the rotation-linear displacement conversion of the adjusting rod 3 to drive the axial movement of the wire rope limiting assembly 2. Combined with the semi-circular groove clamping structure, reliable force transmission is ensured. The unique double-bolt adaptive clamping plate fixing and the axial limiting design of the convex strip 17-baffle ensure stable installation under vibration conditions while supporting rapid disassembly and maintenance. The overall solution fundamentally solves the problem of inaccurate positioning of the loading platform caused by the plastic elongation of the wire rope, significantly improving the operational reliability of the stacker crane and the operational efficiency of the warehousing system without requiring drum disassembly or zero-cost modification.
[0024] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
