Description

Technical Field

[0001] This utility model relates to the field of stacker crane fork technology, and in particular to a telescopic fork support device for a multi-station stacker crane. Background Technology

[0002] The telescopic forks of a stacker crane are the core picking and placing mechanism in an automated storage and retrieval system (AS / RS), installed on the stacker crane. Its main body typically consists of three stages of forks, driven by a motor through chains or gears. The middle and upper forks extend section by section from the fixed lower forks, allowing direct access to goods deep within the racks. After the operation is complete, the forks retract section by section. This ingenious telescopic design allows the stacker crane to accurately and efficiently complete the picking and placing of goods at different depths on both sides of the racks without requiring significant movement within narrow aisles. It is a key piece of equipment for achieving efficient warehouse space utilization and automation.

[0003] During stacker crane operation (such as the lifting mechanism driving the outer frame to rise and fall, and frequent extension and retraction of the forks), vibrations and impacts are generated. Existing devices lack buffering and vibration damping structures, and these vibrations and impacts are directly transmitted to the forks, outer frame, and lifting mechanism connections. Over long-term operation, this can easily lead to loosening of the connection between the forks and the outer frame, accelerated wear of the inner wall, and even deformation of the lifting mechanism guide rails, shortening the overall lifespan of the device, increasing maintenance frequency and costs. Furthermore, existing devices lack convenient disassembly and assembly designs; replacing the forks requires disassembling multiple sets of fixing bolts one by one, and these bolts are prone to rust and stripping under long-term stress, further increasing the difficulty of disassembly. For scenarios requiring frequent replacement of different fork specifications to accommodate irregularly shaped goods, each replacement consumes a significant amount of manpower and time, resulting in prolonged downtime of the stacker crane, severely reducing the overall operational efficiency of the warehouse and failing to meet the "fast turnover, multiple batches" cargo handling rhythm of modern warehouses. Therefore, a multi-station stacker crane telescopic fork support device is proposed to solve the above problems. Utility Model Content

The outer frame 3 serves as a basic frame, connecting the lift 1 and forks 4. A stabilizing mechanism 2 and a replacement mechanism 5 are installed on the outer wall of the outer frame 3. The stabilizing mechanism 2 reduces the friction of the forks 4 during telescopic movement, buffers vibration and impact, ensures the smooth operation of the forks 4, and extends their service life. The inner wall of the outer frame 3 is detachably connected to the forks 4. The forks 4 are used to carry and telescopically transport goods and are the core load-bearing components of the stacker crane. The inner wall of the outer frame 3 is provided with a replacement mechanism 5.
