Abstract

The utility model relates to an aquatic large-sized reinforcing cage hoisting roll-over device, which comprises a reinforcing cage and a rotating bracket, wherein the rear end of the reinforcing cage is arranged on the rotating bracket, so that the reinforcing cage rotates while being hoisted, and a reinforcing hoop of the reinforcing cage is hung by a tipped plate of the rotating bracket so as to support a rear supporting point when in hoisting and to play the safety protection effect. The aquatic large-sized reinforcing cage hoisting roll-over device has the advantages that a single-hook floating crane can be utilized to rapidly hoist the large-sized reinforcing cage in profound zone; an arc supporting beam can ensure the contact among a plurality of main bars of the reinforcing cage and can ensure the completeness of the sections of the reinforcing cage; and four tipped plates which are uniformly distributed on the arc beam are utilized to hang the reinforcing hoop of the reinforcing cage, so that the reinforcing cage is free from rotating relative to the rotating bracket when rotating to the vertical state. The system has the advantages that the hoisting workload of the reinforcing cage is small, the operation safety is high, the requirement on the coordination of the operation driver is low, the labor intensity is reduced, the aquatic floating hoisting configuration requirement is low, the hoisting time of the reinforcing cage is short, the device investment is reduced and the pile forming period can be shortened.

Description

Above-water large-scale reinforcement cage hoisting and overturning device

Technical field

The utility model relates to a kind of bored pile reinforcement cage hoisting and overturning device waterborne, be specially adapted to the long pile cages lifting of abyssal zone major diameter, install, belong to technical field of building construction.

Background technology

Current, large diameter borehole perfusion multi-column pier foundation is widely used in the bridge deep water foundation, during bored pile construction waterborne, steel reinforcement cage needs after the workshop sectional making is finished on the coast, be transported to the pier position with the construction boats and ships, use two loop wheel machines again, or separate unit double hook loop wheel machine is transferred the steel reinforcement cage sections to the hole after horizontality is lifted by crane into plumbness, owing to the harmony and the skill level of crane operator operation are had relatively high expectations with two loop wheel machines or separate unit double hook loop wheel machine lifting steel reinforcement cage, for major diameter, the long segment steel reinforcement cage, because diameter is big, from great, said method causes the hook that rises of two suspension hooks sometimes, put the inharmonious of hook, and collide other member and cause steel reinforcement cage to damage, hull is hit, accidents such as operating personal is injured, prolonged the steel reinforcement cage set-up time, it is more to cause in the hole boring mud to precipitate once more, strengthens the difficulty in the clear hole of secondary, has influenced the pile cycle.

Summary of the invention

The utility model proposes a kind of above-water large-scale reinforcement cage hoisting and overturning device, be intended to overcome the existing in prior technology defective, make the scene, safely, promptly will lie in a horizontal plane in the steel reinforcement cage on the hull with a single hook crane barge, lift by crane into plumbness, shorten the pile cycle on bored pile basis.

Technical solution of the present utility model: it is characterized in that comprising steel reinforcement cage and swivel mount two parts, wherein steel reinforcement cage is bearing on the swivel mount rear end when placing, during reinforcement cage hoisting, only lift by crane front end, the rear end swivel mount rotates with the variation of steel reinforcement cage angle, tangle steel reinforcement cage reinforcement hoop, rear fulcrum supporting and safety precaution effect when bearing lifting by breaking tip plate.

Advantage of the present utility model: adopt a single hook crane barge just can carry out the fast hoisting of abyssal zone large-scale reinforcement cage; The arc supporting beam can guarantee many main muscle contacts of steel reinforcement cage, guarantees the integraty of steel reinforcement cage sections; Utilize uniform on the arc beam four to break tip plate and tangle steel reinforcement cage and strengthen hoop, guarantee that steel reinforcement cage can be when not being rotated into plumbness and swivel mount generation slide relative.This system have guarantee that the reinforcement cage hoisting working out is little, processing safety is high, to operation driver harmony require low, labour intensity reduces, crane barge configuration requirement waterborne is low, the reinforcing bar cage hoisting time short, reduction equipment drops into, save the advantage in pile cycle.

The specific embodiment

Contrast accompanying drawing 1, its structure is the end that swivel mount is fixed on dull and stereotyped barge 1, and steel reinforcement cage 4 leading portions are fixed on the dull and stereotyped barge 1 by interim pad 6, and steel reinforcement cage 4 back segments are fixed on the swivel mount, and crane barge 2 connects suspender 3.

Contrast accompanying drawing 2, its structure is that steel reinforcement cage 4 is lifted by crane by crane barge 2 and suspender 3, steel reinforcement cage 4 and dull and stereotyped barge 1 in vertical state, the reinforcement hoop 5 on swivel mount is broken tip plate 15 and is tangled.

Contrast accompanying drawing 3, its structure be swivel mount by undersetting 7, upper bracket 8, roller pin 9, longeron 10, end floor beam 11, center member 12, arc supporting beam 13, play pin plate socket 14, break tip plate 15 and form, wherein swivel mount undersetting 7 joins by roller pin 9 with swivel mount upper bracket 8, swivel mount undersetting 7 is located in dull and stereotyped barge 1 end, form the steel framework on two end floor beams 11, a center member 12 and two longerons 10, upper bracket 8 is established at longeron 10 middle parts, and arc supporting beam 13 is located on the end floor beam 11.

Contrast accompanying drawing 4, the steel reinforcement cage rear fulcrum is placed on the swivel mount of dull and stereotyped barge 1, and arc supporting beam 13 is fixed on end floor beam 11 tops, establishes on the arc supporting beam 13 and plays tip plate socket 14, play tip plate 15 usefulness latches and fix, break tip plate 15 and block steel reinforcement cage reinforcement hoop 5 with playing tip plate socket 14.

Contrast accompanying drawing 5, its structure are to have upper bracket 8, upper bracket 7 to be fixed on the dull and stereotyped barge 1 in the middle of two longerons 10, are connected with roller pin 9 between upper bracket and undersetting.

Two arc supporting corbels firmly wait to lift an end of steel reinforcement cage on the described swivel mount, play tip plate socket 14 for 4 and are evenly distributed on the arc supporting beam 13, will break tip plate 15 and play tip plate socket 14 and block steel reinforcement cage after fixing and strengthen binding round 5 with latch.
