AI Technical Summary

Technical Problem

Traditional bulk material lifting equipment suffers from severe material spillage during lifting, lacks structural stability and safety, poses safety hazards, and affects operational efficiency and causes environmental pollution.

Method used

Design a lifting device structure that includes a main lifting frame and a sliding lifting frame. The structure adopts a closed design with nested sliding baffles and sliding bottom plates to achieve automatic closure of the lifting frame and bottom sealing, preventing material spillage. The lifting width can be adjusted to accommodate bulk materials of different sizes.

Benefits of technology

It effectively prevents bulk materials from leaking from the side of the spreader, reduces the risk of falling objects from heights, improves the versatility and safety of the equipment, and ensures the stability and efficiency of the lifting process.

Abstract

This application relates to a bulk material lifting device. The bulk material lifting device includes: a main lifting frame with a "U"-shaped frame structure; sliding lifting frames that are telescopically mounted on both sides of the main lifting frame; a reinforcing frame, a main frame baffle, and a main frame base plate mounted on the main lifting frame; an openable and closable movable door on the door frame of the sliding lifting frame; a sliding baffle mounted on the sliding surface of the sliding lifting frame; a sliding base plate mounted at the bottom of the sliding lifting frame; the other end of the sliding base plate being mounted in a sliding groove mounted on the vertical frame of the main lifting frame; and lifting lugs respectively mounted on the top of the door frames of the sliding lifting frames at both ends of the main lifting frame. The solution provided by this application enables the main lifting device structure to be formed by the main lifting frame and the sliding lifting frame. Combined with the nested sliding structure of the main frame baffle and the sliding baffle, the lateral gaps are automatically closed during the extension and retraction of the lifting frame, solving the problem of bottom plate joints in traditional lifting buckets, reducing the risk of falling objects from heights, and allowing for free extension and retraction of the sliding lifting frame, thus improving the equipment's versatility.
