Novel ultra-wide front fulcrum cable-stayed hanging basket thrust device

Abstract

The invention discloses a novel ultra-wide front fulcrum cable-stayed hanging basket thrust device which comprises a supporting block, a fixed support and a movable support, wherein the supporting block is provided with a penetrating cross rod, a horizontal square steel column, a first fixing steel bar and a first supporting foot; the fixed support comprises an antiskid plate, an L-shaped supporting plate and a lock catch frame, and a rectangular groove of a bottom plate of the lock catch frame is riveted with a female head lock catch; a rectangular groove of a top plate of the movable supportis riveted with a male head lock catch, a U-shaped plate of a female head lock catch and a U-shaped plate of the male head lock catch are clamped together to form a rectangular frame structure, and ahorizontal square steel column is movably sleeved with the rectangular frame structure. The invention further provides a corresponding use method. The female head lock catch and the male head lock catch with simple U-shaped frame structures are adopted; clutch locking and unlocking can be achieved only through forward and reverse sliding of the walking mechanism, namely, the whole walking-thrust-unloading work is completed, the mounting, fixing and dismounting process is simple, convenient and clear, the laying process of the cable-stayed hanging basket embedded part is greatly shortened, andthe hanging basket pouring construction speed of the cable-stayed bridge is increased.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a novel ultra-wide front fulcrum stay cable hanging basket thrust device. Background technique [0002] The construction of the front fulcrum stay cable hanging basket is widely used in the bridge construction process of the cable-stayed bridge. For the bridge deck with a small width, the double C hanging lug walking structure can be used. However, due to the passing rate requirements of modern traffic, the width of the bridge deck is becoming wider and wider. At this time, the double C hanging lug walking structure may not be able to support the hanging basket. Therefore, it is necessary to lay a special walking track on the beam section that has been poured. . [0003] In the construction process of the front fulcrum stay cable hanging basket of the ultra-wide bridge deck, it is generally necessary to lay more than 4 special walking tracks on the beam section that ...
