Description
Technical field
The utility model relates to a kind of bridge-turning construction equipment in construction of road and bridge, is specially a kind of bridge and accurately turns and rotate and draw-gear.
Background technology
Bridge Rotation Construction Technique refers to be made bridge construction after (cast or splicing) moulding, by a kind of construction method in place of turning in non-design axial location.It can be converted into the operation in obstacle overhead on the bank or subaerial operation.Construction Technology of Level Swing Method can overcome preferably high mountain gorge, The water is deep and the current fast or the river course of often navigation on set up large span structure difficulty, especially, to building in the busy urban interchange of communications and transportation and railroad underbridge, its advantage is more obvious.According to the rotation direction of bridge construction, it can be divided into flat turn, vertical transfer and flat turn, method that vertical transfer combines, wherein in the majority with the method for flatting turn.The key technology of construction by swing is rotating machinery and supporting pulling equipment.Rotating machinery and turning power play an important role to Bridge Rotation Construction Technique, and therefore the tumbler of bridge rotary part is done to corresponding improvement can provide reliable quality assurance to bridge construction.
Summary of the invention
The utility model, for solving the problem at Bridge Rotation Construction Technique, provides a kind of bridge accurately to turn and has rotated and draw-gear.
The technical solution of the utility model is, a kind of bridge is accurately turned and rotated and draw-gear, and structure comprises: upper mounting plate, lower support platform, spherical support body, stabilizing ring, hydraulic jack, insurance supporting leg, the brace table of turning, orbit ring, orbit ring locating piece; Described upper mounting plate below arranges lower support platform, lower support platform below is provided with spherical support body, described spherical support body center is provided with positioning rotating shaft, below upper mounting plate, the position of all sides of lower support platform is provided with stabilizing ring, and stabilizing ring is provided with hydraulic jack and insurance supporting leg, at hydraulic jack top, be provided with wheel, in the brace table of turning, be provided with rounded channels, rounded channels is provided with orbit ring around, and orbit ring is provided with orbit ring locating piece.Described spherical support surface is provided with radial rib, is provided with radial slot in rounded channels, and described upper mounting plate is around wound around and is provided with cable wire and traction fluid compressing cylinder, and traction fluid compressing cylinder connects cable wire, and described traction fluid compressing cylinder is connected with oil pump by oil pipe.
The setting that the utility model has been used hydraulic jack and orbit ring to coordinate, is separated from each other a setting analysis by upper mounting plate and lower support platform, can make bridge rotating become than being easier to.In described spherical support surface, be provided with radial rib, in rounded channels, be provided with radial slot cooperatively interact can make bridge reach certain angle and oil cylinder pressure release mutually chimeric after, mutually frictional force increases and prevents that bridge generation from rotating naturally, on orbit ring, be provided with locating piece, play the effect of brake, can place rotation process medium velocity the problem of rotating occurred soon.
Device described in the utility model has rational in infrastructure, easily promotes, and saves oil consumption, shortens construction period, simplifies trailer system, has avoided the problems such as ball pivot processing break-in, and safe and reliable, efficiency of construction is high, the stability advantages of higher of bridge.
