Description

Technical Field

[0001] This utility model relates to the field of stacker-reclaimer technology, specifically to a rotary anchoring device for stacker-reclaimers. Background Technology

[0002] A stacker-reclaimer is a large, continuous loading and unloading equipment used in bulk material yards. It is primarily used for the storage, retrieving, and transfer of bulk materials such as coal, ore, cement, and grain. Combining stacking and retrieving functions, it significantly improves material handling efficiency through highly efficient and automated operation. It is widely used in industrial fields such as ports, power plants, steel mills, and mines. A stacker-reclaimer typically consists of a traveling mechanism, a slewing mechanism, a pitching mechanism, a boom system, and a conveyor belt. The entire machine moves via a trolley, the slewing mechanism adjusts the operating angle, the pitching mechanism controls the boom height, and the conveyor belt transports the material. Based on structural form, it can be classified as cantilever, bridge, and... Among various types, such as gantry cranes, cantilever stacker-reclaimers are the most common due to their high flexibility. Their booms can rotate and tilt to adapt to different shaped stockpiles. The core functions of a stacker-reclaimer include two modes: stacking and reclaiming. In stacking mode, materials are delivered to the boom conveyor belt via an external conveyor system and then scattered from the front end of the cantilever to form a stockpile. In reclaiming mode, reclaiming devices (such as bucket wheels and scrapers) dig materials from the stockpile and transfer them to downstream equipment via the boom conveyor belt. Its automated control system can integrate PLC, sensors, and remote monitoring technology to achieve precise positioning, automatic optimal material reclaiming, and collision protection, thereby improving operational safety and energy efficiency.

[0003] Existing stacker-reclaimers have a high center of gravity and a large windward area for their conveyor arms. Under special weather conditions, such as strong winds or gusts, the rotational torque is too large, making it impossible to effectively brake the slewing mechanism. This causes the boom to rotate, resulting in uncontrollable equipment. Furthermore, existing stacker-reclaimers produce a certain degree of swaying during slewing, affecting the stability of the stacker-reclaimer during slewing and easily causing equipment damage accidents. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4This utility model provides a rotary anchoring device for a stacker-reclaimer, including a stabilizing disc 100. A docking groove 110 is formed on the outer side of the stabilizing disc 100, and a docking ring 111 is integrally formed on the outer side of the docking groove 110. An installation chamber 120 is fixedly connected to the top of the stabilizing disc 100. A through groove 130 is formed on the top of the installation chamber 120, and an installation frame 140 is fixedly connected to the top of the installation chamber 120. A sliding frame 141 is slidably connected to the outer side of the installation frame 140, and an anchoring sleeve 1 is fixedly connected to the outer side of the sliding frame 141. 50. Anchor sleeve 150 is located inside through groove 130. Mounting rod 160 is fixedly connected to the outside of mounting frame 140. Two telescopic rods 161 are fixedly connected to the outside of mounting rod 160. Rotating lever 170 is rotatably connected to the outside of sliding frame 141. Rotating lever 170 is fixedly connected to telescopic rod 161. Two mounting plates 180 are fixedly connected to the top of mounting chamber 120. Locking bolt 181 is screwed to one side of mounting plate 180. One end of locking bolt 181 passes through mounting plate 180 and mounting frame 140.

[0022] Specifically, in windy weather, the locking bolt 181 is rotated to release its screw connection with the mounting plate 180. Then, the locking bolt 181 is disassembled, releasing its limiting fixation on the rotating lever 170. Subsequently, the sliding frame 141 connected to the rotating lever 170 slides downwards due to gravity because the rotating lever 170 is in contact with the limiting fixation. This causes the anchoring sleeve 150 mounted on the sliding frame 141 to descend and lock with the anchoring pin 300 below, thus locking the rotating device. When the weather is good, pressing the raised rotating lever 170 causes it to lift the sliding frame 141, raising the anchoring sleeve 150 and releasing its locking relationship with the anchoring pin 300. Then, the locking bolt 181 is installed into the mounting plate 180 to fix the mounting frame 140.

[0023] Example 2: Please refer to again Figure 1-4 A docking wheel 200 is provided on the outer side of the stabilizing wheel 100. A stabilizing groove 210 is provided on the outer side of the docking wheel 200. The stabilizing groove 210 is engaged with the docking groove 110. A stabilizing ring 220 is fixedly connected to the outer side of the stabilizing groove 210. The stabilizing ring 220 is engaged with the docking ring 111. A rotating wheel 221 is rotatably connected to the outer side of the stabilizing ring 220. The rotating wheels 221 are evenly distributed and are in contact with the docking ring 111. An anchoring pin 300 is provided below the stabilizing wheel 100. The anchoring pin 300 is located below the anchoring sleeve 150.

[0024] Specifically, the docking groove 110 on the stabilizing wheel 100 contacts the stabilizing groove 210 on the docking wheel 200, so that the docking groove 110 and the stabilizing groove 210 cooperate to prevent the rotating mechanism from shaking due to external factors during rotation. At the same time, the docking ring 111 on the stabilizing wheel 100 contacts the stabilizing ring 220 on the docking wheel 200, and the rotating wheel 221 on the docking wheel 200 reduces the friction between the stabilizing wheel 100 and the docking wheel 200, preventing the rotating mechanism from shaking due to external factors during rotation.

[0025] Working principle: In windy weather, the locking bolt 181 is rotated to disconnect it from the mounting plate 180. Then, the locking bolt 181 is removed, thus releasing its limiting fixation on the rotating lever 170. Subsequently, the sliding frame 141 connected to the rotating lever 170 slides downward under the influence of gravity because the rotating lever 170 is in contact with the limiting fixation. This causes the anchor sleeve 150 installed on the sliding frame 141 to descend and lock with the anchor pin 300 below, thus locking the rotating device. When the weather is good, pressing the raised rotating lever 170 causes it to drive the sliding frame 141 to rise, causing the anchor sleeve 150 to rise and releasing its locking relationship with the anchor pin 300. Then, the locking bolt 181 is installed into the mounting plate 180 to fix the mounting frame 140.

[0026] The docking groove 110 on the stabilizing wheel 100 contacts the stabilizing groove 210 on the docking wheel 200, so that the docking groove 110 and the stabilizing groove 210 cooperate to prevent the rotating mechanism from shaking due to external factors during rotation. At the same time, the docking ring 111 on the stabilizing wheel 100 contacts the stabilizing ring 220 on the docking wheel 200, and the rotating wheel 221 on the docking wheel 200 reduces the friction between the stabilizing wheel 100 and the docking wheel 200, preventing the rotating mechanism from shaking due to external factors during rotation.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
