The invention provides an inner sliding frame and bridge frame structure assembly for a three-way fork. The inner sliding frame and bridge frame structure assembly comprises a bridge frame and an inner sliding frame. The inner sliding frame comprises a first rack, a first structure protruding part and a clamping groove. The first rack comprises a main roller vertical plate and a rack structure; the bridge comprises a first main roller, a first auxiliary roller, a transmission shaft and a gear. Longitudinal movement of the inner sliding frame and the bridge frame is limited through cooperation of the main rolling wheels, the auxiliary rolling wheels and the racks, and meanwhile longitudinal loads (cargo gravity) from loads are borne, so that the system is more stable; the rack is provided with a clamping groove and a protruding part, the bearing capacity is higher, and the service life is longer; and meanwhile, the racks on the upper side and the lower side are matched with the gears to bear transverse torque from loads, so that the system is more stable. The inner sliding frame and bridge frame structure assembly for the three-way fork has high stability and good durability.

This invention discloses a method and system for parsing and verifying multi-format documents. The method includes: receiving a document to be parsed and generating a source file artifact record; identifying the document type and determining a standardized PDF file, performing validity verification, and generating a standardized PDF artifact record for association; submitting a parsing request using the standardized PDF as unified input, recording the request artifact, and receiving an external task identifier; obtaining the parsing result based on the task identifier and generating a parsing result artifact record, establishing a multi-dimensional association between the result and the source file, PDF, and request record; recording the task's lifecycle events and performing phased verification; and forming a document parsing artifact chain based on the artifact records and lifecycle events at each stage. This invention, by establishing a unified visual benchmark and a mesh-like link association, significantly improves parsing accuracy while achieving precise anomaly localization and data closed-loop auditing throughout the entire lifecycle.
