Description

Technical Field

[0001] This invention belongs to the field of container protection technology, specifically a safety protection structure for a lift-up storage container. Background Technology

[0002] Containers are mainly used to store parts, tools and small materials in warehouses. Lift-access containers are shelves that can adjust the storage position of pallets, enabling three-dimensional storage of materials, saving storage space and enabling fast inbound and outbound operations. During the use of lift-access containers, safety protection is required to avoid injury to staff. Therefore, a safety protection structure for lift-access containers is needed.

[0003] The existing safety protection structure of lifting storage containers is ineffective because the containers are usually open. The lifting seat on the outside of the container moves the pallet up and down, and the drive mechanism stores and retrieves the materials on the pallet. However, the lifting seat is in direct contact with the external environment during use, which causes impurities to adhere to the drive mechanism. This leads to accelerated wear of the drive mechanism, reduced equipment accuracy and lifespan, damage to goods and equipment failure, and reduced effectiveness of the container.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention can reduce external impurities and drive mechanism by setting the container box and storage box, reduce impurity wear of drive mechanism, extend the service life of drive mechanism, and the lifting seat is guided by the lifting guide block and the guide seat in the container. With the synchronous drive of the double-sided lifting screw structure, the lifting process is guaranteed to be smooth and without deviation. The docking and positioning of the lifting seat with each layer of storage pallet and transfer table is accurate, eliminating the risk of transfer jamming caused by alignment deviation. The lifting seat, synchronous belt and transfer bar can push the pallet smoothly.

[0016] (2) The present invention forms a double-closed protection of the storage and retrieval channel by setting up the storage and retrieval box and negative pressure equipment, and using the first protective plate and the second protective plate together to isolate the external environment from entering the container. With the adsorption box and the treatment box, it can block the external dust from entering the container and clean the impurities attached to the pallet surface to prevent impurities from entering the container box. The filter ring, rotating ring and filter screen filter the impurities, and the dust on the surface of the filter screen is scraped off by the rotating toothed ring, cleaning scraper, main missing gear and rotating gear. The filter screen does not need to be manually disassembled, realizing the filter screen self-cleaning online. The sealing screw structure of the main missing gear makes the sealing block open and close synchronously with the cleaning action. During the cleaning operation, the feeding channel is automatically opened and the scraped impurities fall into the collection box for centralized recycling. In the non-cleaning state, the sealing block closes the feeding channel to avoid negative pressure leakage and weakening the dust removal effect. This reduces the frequency and cost of manual maintenance and does not require machine shutdown for cleaning, ensuring the normal use of the container. At the same time, it avoids secondary dust pollution during the cleaning process and improves the use effect of the safety protection structure. Attached Figure Description
