Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane lifting mechanism with a protective structure. Background Technology

[0002] Stacker cranes are modern automated logistics equipment widely used in warehouses, sorting centers, and other similar locations. Their main function is to move goods from the receiving area to the outgoing area according to pre-set rules and store them in a specific stacking pattern. The mechanical structure of a stacker crane mainly includes a lifting mechanism, a traveling mechanism, a loading mechanism, and a control system.

[0003] A search of existing technologies revealed a Chinese patent for "A Lifting Mechanism for a Stacker Crane," application number "202221725402.4."

The lifting mechanism includes a fixing plate, a winding roller, a reducer, a rotating shaft, a motor, a support plate, a fixed pulley, and a steel cable. The conveying mechanism includes a fixed frame, a Mecanum wheel, a servo motor, a limiting block, a storage plate, a positioning pin, and a cylinder. While this utility model is simple in structure, practical, and widely applicable, the power for the lifting mechanism comes from the steel cable, winding roller, and motor, lacking effective emergency protection measures. During the operation of stacker cranes, abnormal problems such as cable breakage due to long-term wear, aging, or sudden external forces, as well as sudden power failures, exist. The aforementioned stacker crane lifting mechanisms are insufficient to ensure the safety of equipment and goods in handling such unexpected situations. Therefore, this utility model provides a stacker crane lifting mechanism with a protective structure to solve the problems mentioned in the background art. Utility Model Content

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5 This utility model discloses a stacker crane lifting mechanism with a protective structure, comprising a base 1, a top plate 3 fixedly connected to the top of the base 1 by two columns 2, a lifting plate 4 slidably connected between the columns 2, and sliding plates 5 slidably connected to the outer sides of the columns 2. The sliding plates 5 are fixedly connected to the lifting plates 4. A steel cable 8 extending to the top of the top plate 3 is fixedly connected to the top of the sliding plates 5. A detection component is provided on the top of the top plate 3. The detection component includes two infrared fences 22 symmetrically arranged on both sides of the steel cable 8, a baffle 18 movably connected between the infrared fences 22 and located above the infrared fences 22, a fixed plate 17 fixedly connected to the top of the top plate 3, and two sliders 21 slidably connected inside the corresponding fixed plate 17. The infrared fences 22 are fixedly connected to one side of the fixed plate 17, the baffle 18 is fixedly connected between the sliders 21 and inserted through the outer side of the steel cable 8, and a roller 20 is installed inside the baffle 18 and located at the top of the steel cable 8 to reduce friction between the baffle 18 and the steel cable 8.

[0026] The steel cable 8 serves as the power source for the lifting platform 4. The rewinding of the steel cable 8 can drive the carrying platform 10 and the goods on it upwards via the sliding plate 5 for stacking operations. Under normal conditions, the baffle 18 is supported by the steel cable 8 and remains positioned above the infrared fence 22, ensuring the entire lifting mechanism operates normally. When the steel cable 8 breaks, the baffle 18 loses its support and falls under gravity between the infrared fences 22. The baffle 18 blocks the infrared fences 22, which respond quickly. The trigger signal from the infrared fence 22 serves as the signal for the steel cable 8 breaking, controlling the triggering of the anti-fall components to prevent the goods from falling. This ensures timely protective measures are taken in the event of a steel cable breakage, improving the safety of the stacker crane's lifting mechanism.

[0027] To further enhance the safety of the lifting mechanism, the slide plate 5 is equipped with an anti-fall component. The anti-fall component includes a metal insert plate 12 that is slidably connected inside the slide plate 5, an electromagnet 13 that is fixedly connected to the inside of the slide plate 5 and located on the side of the insert plate 12 away from the column 2, and two springs 14 that are symmetrically fixedly connected to the outside of the insert plate 12 and located on both sides of the electromagnet 13. The column 2 has a slot 6 on the side close to the slide plate 5, and multiple baffles 7 are fixedly connected at equal intervals inside the slot 6.

[0028] The power supply of electromagnet 13 is kept on the same line as the power supply of winch 9. When the external system loses power unexpectedly, electromagnet 13 loses power, and the plug plate 12 is quickly inserted into the slot 6 of column 2 under the extension of spring 14. The baffle 7 is used to prevent the lifting plate 4 from falling, ensuring that protective measures can be taken in time in the event of power failure.

[0029] A winch 9 is fixedly connected to the top of the top plate 3 as the power source for lifting. A U-shaped mounting frame 15 is fixedly connected to the top of the top plate 3 and on both sides of the fixed plate 17. Pulleys 16 are installed on the top of the mounting frame 15 and the top of the top plate 3. A guide wheel 19 is installed on the side of the top plate 3 near the column 2. The top of the steel cable 8 passes through the outer side of the guide wheel 19 and between the pulley 16 and connects to the winch 9.

[0030] The winch 9 installed on the top plate 3, together with the pulley 16 and guide wheel 19, ensures the smooth operation of the steel cable 8, driving the lifting and lowering of goods for stacking work.

[0031] The top of the lifting plate 4 is provided with a bearing plate 10 for directly supporting goods. Multiple pressure sensors 11 are evenly installed between the bearing plate 10 and the lifting plate 4. The pressure sensors 11 can detect the weight of the goods to prevent the stacked goods from exceeding the safety value and prevent overload from causing safety accidents.

[0032] The infrared fence 22 is electrically connected to the electromagnet 13. When the infrared fence 22 detects that the steel cable 8 is broken, it will immediately trigger the electromagnet 13 to lose power, so that the insert plate 12 can be quickly inserted into the slot 6 to achieve emergency braking and fall protection.

[0033] Working principle: When the steel cable 8 breaks, the baffle 18 loses its support and falls between the infrared fences 22 under the action of gravity. The baffle 18 blocks the infrared fences 22, and the infrared fences 22 respond quickly. The trigger signal of the infrared fences 22 serves as the signal that the steel cable 8 has broken, triggering the electromagnet 13 to lose power, causing the insert plate 12 to quickly insert into the slot 6, realizing emergency braking and fall protection, and ensuring that protective measures can be taken in time in the event of the steel cable 8 breaking.

[0034] When the external system experiences an unexpected power outage, the electromagnet 13 loses power, and the insert plate 12 quickly inserts into the slot 6 of the column 2 under the extension action of the spring 14. The baffle 7 prevents the lifting plate 4 from falling, ensuring that protective measures can be taken in time in the event of a power outage to prevent the goods from falling and improving the safety of the stacker crane's lifting mechanism.

[0035] The dual protection mechanism design not only enables a rapid response when the steel cable 8 breaks, but also provides reliable safety protection in case of power failure or other emergencies. This greatly improves the safety and reliability of the stacker crane's lifting mechanism, reduces safety hazards caused by equipment failure or external factors, and provides strong protection for the safe operation of the stacker crane.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
