Abstract

The invention relates to a positioning device used for a pre-embedded part of a quick spring-bar fastener, comprising a sleeper mould soleplate used for fixing the pre-embedded part of the quick spring-bar fastener. 'Sunken' glyph pre-set holes which are symmetrical to two sides of a rail are cut on the sleeper mould soleplate, and sealing glue strips are fixed around hole walls of the 'Sunken' glyph pre-set holes and the holes are fixed by a mould fixing pressing-board and bolts, and the pre-embedded part of the quick spring-bar fastener is positioned in the 'Sunken' glyph pre-set holes. Projecting parts corresponding to the concave parts of the 'Sunken' glyph pre-set holes on the sleeper mould soleplate are adopted as sliding channels, a sliding pressing-sheet is respectively arranged in the internal part of the sliding channels, the outer ends of the sliding pressing-sheets are extended into the 'Sunken' glyph pre-set holes, the inner ends of the sliding pressing-sheet are connected with springs, the other ends of the springs are connected with the bolts, and a cover is fixed with bolts above the sliding channel. A positioning adjusting block is fixed on a positioning device fixing soleplate welded on the sleeper mould soleplate to quickly and accurately position the pre-embedded part of the quick spring-bar fastener onto the concrete sleeper mould so as to guarantee the quality of products.

Description

(1) Technical field [0001] The invention relates to a fixing device and a positioning method for embedded parts of concrete sleeper fasteners. (2) Background technology [0002] In the production of concrete sleepers, it is necessary to pre-embed the clip sleeper fasteners. The traditional embedded parts of the clip sleeper fasteners are fixed by a device that uses a cone to clamp the round tube of the fastener. The disadvantage of this fixing method is that the two curved surfaces cannot be tightly locked. During the vibration of the sleeper, the fixing device of the cone and the round tube of the fastener will slide relative to each other, causing a large error in the positioning of the fastener and defective products. and higher scrap rates. This fixing method is especially not suitable for Pandrol's new fast clip fastening embedded parts. The fixing method of this fastener has become a major problem in the production of Type III sleepers. (3) Contents of the invention...
