AI Technical Summary

Technical Problem

The hydraulic hoses of the vibrator rods of existing slipform jacks are easily washed away by concrete, making cleaning difficult. Furthermore, traditional handheld high-pressure water guns are ineffective for cleaning, especially for lumpy concrete.

Method used

The design incorporates an insertable vibratory tamping integrated shoulder protection slipform, employing upper and lower protective sleeves to protect the hydraulic pipes. Combined with scraper and water flow rinsing, it achieves comprehensive cleaning of the vibratory rod head. The cleaning method combines scraper sweeping and water flow impact, while the vibratory rod is supported by elastic elements to prevent wear.

Benefits of technology

It effectively protects hydraulic pipes, reduces cleaning difficulty, improves the cleaning effect of vibrator head, avoids water flow erosion of sealing connection failure, reduces wear, and ensures vibration effect.

Abstract

The invention belongs to the technical field of shoulder pad slip forms, and particularly relates to an insertion type vibrating integrated shoulder pad slip form which comprises a die, a feeding bin and a vibrating rod, an upper protective sleeve used for allowing the vibrating rod to penetrate through from top to bottom is arranged in the feeding bin, and a lower protective sleeve capable of rotating and containing a vibrating rod head in the vibrating rod is arranged at the bottom of the upper protective sleeve. An upper flushing channel capable of flushing the surface of the vibrating rod head in the lower sheath from top to bottom is arranged in the upper sheath, a scraping plate capable of scraping and sweeping the surface of the vibrating rod head during rotation is arranged in the lower sheath, an elastic piece for providing force for the scraping plate to abut against the surface of the vibrating rod head is arranged in the lower sheath, and the inner surface of the scraping plate comprises a plurality of sawteeth; an inner flushing channel with the top end penetrating through the top of the scraping plate is arranged in the scraping plate, and inner flushing openings are evenly formed in the position, between every two adjacent sawteeth, of the inner side face of the inner flushing channel. The protective performance and the flushing efficiency of the vibrating rod are improved, and the problems that in the prior art, the protective effect of the vibrating rod is poor, flushing is inconvenient, and the flushing effect is poor are solved.
