Mobile formwork front outrigger base

Abstract

The invention discloses a front outrigger base of a mobile formwork, which comprises a supporting base, a length adjustment mechanism and a fastening system for the front outriggers. Bolts are connected, and box-shaped cantilevers are symmetrically arranged on both sides of the box-shaped steel structure. The box-shaped cantilever is equipped with a front leg fastening system for connecting the embedded parts of the pier. The box-shaped steel structure is fixed in the middle cavity. The length adjustment mechanism on the pier not only realizes the function of uniform bearing capacity of the front outrigger and avoids partial load, but also realizes the function of independent adjustment of the length of the left and right outriggers of the front outrigger, and prevents the fulcrum of the front outrigger from moving back and forth, left and right, and detached The function of bridge piers, thus improving the safety of mobile formwork construction.

Description

technical field [0001] The invention relates to the technical field of railway construction auxiliary equipment, in particular to a front outrigger base of a mobile formwork. Background technique [0002] The mobile formwork is a construction machinery and equipment for pouring concrete beams hole by hole, including the main beam, front outriggers, rear outriggers and lower guide beams. The axis moves longitudinally, the weight of the mobile formwork is more than 400 tons, and the weight of the concrete beam produced is more than 800 tons. [0003] The front leg is one of the supporting structures of the main body of the mobile formwork, and its lower end is supported on the pier platform. The unevenness of the platform on the pier often causes the front outriggers to be partially loaded, resulting in structural eccentric loads, which affects the safety of the mobile formwork operation; the mobile formwork host needs to shrink the front outriggers when the host is in place,...

AI Technical Summary

Problems solved by technology

The unevenness of the platform on the pier often causes the front outriggers to be partially loaded, resulting in structural eccentric loads, which affects the safety of the mobile formwork operation; the mobile formwork host needs to shrink the front outriggers when the host is in place, and the host needs to be stretched when it is in place. The front outriggers, and because the heights of the two platforms of the bridge pier may be different, the length of the left and right outriggers needs to be adjusted independently; the position of the legs of the mobile formwork determines the position of the concrete beam, so the fulcrum needs to be fixed on the bridge pier, And it needs to play a role in preventing the host from tipping over
