Self-climbing hydraulic formwork turning system for high pier

Abstract

The invention provides a high pier self-climbing hydraulic template overturning system which can lighten a template releasing process and can achieve automatic template overturning and climbing. The high pier self-climbing hydraulic template overturning system includes a template, an outer frame, template overturning and climbing systems, and crank arms; the template includes an upper template body and a lower template body; template beams are fixedly arranged on back surfaces of the upper template body and the lower template body; the outer frame includes a vertical guide rail; the vertical guide rail is arranged outside the template; one ends the crank arms are connected to the vertical guide rail, and the other ends of the crank arms are detachably connected to the upper template body;each template overturning and climbing system includes telescopic devices and a lifting device, the lifting device is slidingly connected to the vertical guide rail in the vertical direction, the telescopic devices are connected to an upper end and a lower end of the lifting device respectively, and the telescopic devices are detachably connected to the upper template body and the lower template body through the template beams; and the crank arms, the vertical guide rail and the template beams define a template lifting space for allowing the template to pass. Alternative lifting of the template and the outer frame can be achieved, lightweight is achieved in the template releasing process, and automatic template overturning and climbing can be achieved, and the template overturning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold turning technology for high bridge piers, in particular to a self-climbing hydraulic mold turning system for high piers. Background technique [0002] High piers are more common in the bridge pier structures of railways and highway bridges in mountainous areas. Common forms and scaffolding systems for bridge pier construction include floor type, sliding mode, and turning mode. In the current construction of high bridge piers, ground-mounted scaffolding construction methods are basically not used. Cantilevered scaffolds need to bury cantilever beams in the pier body. The metal surface of the girder is exposed, and the pier body is polluted by rust spots due to metal rust. The sliding form method often uses a chain block or a through-hole hydraulic jack to lift the formwork as a whole, and the lifting frame is generally supported by a steel bracket permanently embedded in the pier body. Due to the ad...

Problems solved by technology

According to the analysis, the existing mold turning methods mainly include: a. tower crane + manual mold turning; b. tower crane + chain hoist turning mold; c. tower crane + through-heart hydraulic jack turning mold; d. hydraulic lifting frame + follow-up type Turnover of small tower cranes; in summary, the existing turning over method is basically a manual + mechanical method, especially the turning over process has not been automated, resulting in a long time for the turning over process
