Small cross beam for connection of scraper conveyor

Abstract

The invention discloses a small cross beam for connection of a scraper conveyor. The small cross beam comprises an E-shaped bolt, a connecting disc, a T-shaped bolt, a pressing plate I and a pressing plate II, wherein arc grooves are arranged at the two sides of an isosceles-trapezoid-shaped base; the central position of the upper surface of the connecting disc is provided with an isosceles-trapezoid-shaped groove matched with the isosceles-trapezoid-shaped base and installing holes positioned at the two sides of the isosceles-trapezoid-shaped groove; the bottom surfaces of the pressing plate I and the pressing plate II are provided with arc pressing plates fastened with the arc grooves; and the central position of the pressing plate I is also provided with a through hole. The small cross beam disclosed by the invention has the beneficial effects that the E-shaped bolt and the connecting disc adopt a connecting manner of the isosceles-trapezoid-shaped groove and the base and are matched with the arc grooves and arc pressing blocks of the pressing plates for fastening, so that under the same condition, the parallelism and the verticality of the small cross beam in the use process are guaranteed, the working efficiency is improved, and higher use requirements are met. The small cross beam disclosed by the invention has the characteristics of simple structure and convenience in use.

Description

technical field [0001] The invention relates to a small beam used for connecting scraper conveyors, and belongs to the technical field of scraper conveyor equipment accessories. Background technique [0002] The small balance beam (E-bolt) is an accessory that plays a connecting role in the scraper machine. It has strict technical requirements. After processing, the center distance of each E-bolt must be within the required range, and the three bolt columns are all within The error on the same plane does not exceed ±0.5mm. However, the existing method is to use conventional lathe fixtures to process E-bolts. At the same time, the existing E-bolts have a single connection method, which cannot guarantee their parallelism and perpendicularity requirements. , thus unable to meet the higher requirements for use, the work efficiency is extremely low, the processing tasks of accessories cannot be completed, and the quality of the products is also poor.
