Description
Technical field
The utility model relates to T roof beam structure equipment in inter-city passenger rail, speedway, the railway Line of Existing Railway improvement project, is a kind of balanced type single conducting beam bridge formation machine specifically, can realize radius of curvature setting up more than or equal to 500 meters single line or double track railway T beam.
Background technology
At present, the widely used bridge formation machine that has 2 kinds of structures in construction of China railways ew line and the old line transformation.The one, single-beam simply-support, as JQ series, triumph type, DJK140 type; The 2nd, the twin beams simply-support is a type as Long March series and red flag.Single-beam simply-support bridge formation machine center of gravity is lower, walking safety, and horn is scalable, the traveling of can under the semi-cantilever operating mode, relying on oneself, and can lay the bridge floor section of track and upgrade short rail by cantilever.On curve and ramp circuit, can utilize horn yaw and new line, nodding action to fulfil assignment.Feeding beam voluntarily when setting a roof beam in place does not need to lay the end of the bridge siding, and construction adaptability is strong.Its major defect is that (except the JQ series) beam that can not directly fall when setting up the chip beam is in place, adopts the walking operation, and is time-consuming and safety is relatively poor.Two-way the setting a roof beam in place of twin beams freely-supported bridge formation function for another example, the beam that can directly fall when setting up the split blade type beam is in place, but the huge heaviness of body, slow from line speed, mobility is poor.Be subjected to the restriction of end of the bridge site condition bigger, construction adaptability is poor.Need freely-supported during the shop bridge floor section of track, change short rail difficulty, the efficient of working continuously is not high, and needs to disintegrate during long-distance transport, and assembling is inconvenient.
In sum, above-mentioned two kinds of bridge formation machines are supporting body with the railway locomotive all, and need be equipped with railway locomotive and transport the T beam, and efficiency of construction is low, the equipment cost height.Along with the development of construction technology, the site prefabrication technology is used more and more widely, has become present developing direction.
Summary of the invention
In view of above-mentioned present situation, the purpose of this utility model provides a kind of balanced type single conducting beam bridge formation machine, can realize radius of curvature setting up more than or equal to 500 meters single line or double track railway T beam.
For achieving the above object, the balanced type single conducting beam bridge formation machine that the utility model provides comprises girder and goes up rear support leg, front leg strut and the middle supporting leg of installing; On girder, be provided with rane trolley; With dispose independently Beam transportation vehicle; Wherein, described girder is the girder of one two straddle type; The supporting leg lower transverse beam is provided with vertically and horizontally walking mechanism in described; And have the hoist lifting mechanism of rear support leg lower transverse beam displacement of a control.Therefore, dolly can vertically move along girder ear beam by walking mechanism, by the transverse-moving mechanism on it, can make the traversing design attitude that drops down onto of concrete T-shaped beam.
According to such scheme, related middle supporting leg lower transverse beam vertically and horizontally walking mechanism comprises that symmetrically arranged middle supporting leg lower transverse beam is provided with two groups of road wheels; And the longeron that is arranged with between the supporting leg lower transverse beam in two is provided with two groups of road wheels.Transverse-moving mechanism is stressed when setting a roof beam in place, but traversing two-wire or the highway multi-disc beam of setting up of complete machine hanging beam; It is stressed to be converted to vertical shift mechanism during via hole, supports the anterior weight of bridge formation machine and along the bridge floor track travel.
Further, related rear support leg lifting mechanism comprises on the rear support leg lower transverse beam being symmetrically installed with wire rope, is connected with the electric block that is provided with on the girder.Therefore, promote the rear support leg lower transverse beam when setting a roof beam in place, removing obstacles makes Beam transportation vehicle carry beam to enter smoothly, can put down during via hole in order to support bridge formation drive end unit weight and along the bridge floor track travel.
The girder of two mentioned straddle types is meant that the length of girder is across two bridge piers in the utility model.Be mainly used in concrete T-shaped beam new line, the uneven horizontal problem of nodding when striding of solving.
In a word, the balanced type single conducting beam bridge formation machine that the utility model provides, because of girder is to adopt two straddle type girders, be equipped with on the ear beam that has by both sides, girder below two rane trolleys and on the hoisting mechanism that is equipped with and assembly pulley in order to the traversing design attitude that drops down onto of lifting concrete T-shaped beam; In addition, also having one can folding rear support leg lower transverse beam, opens when setting a roof beam in place to make Beam transportation vehicle carry beam to enter, can be closed during via hole to support bridge formation drive end unit weight and along the bridge floor track travel.In addition, be provided with vertically and horizontally walking mechanism at middle supporting leg lower transverse beam, transverse-moving mechanism is stressed when setting a roof beam in place, but traversing two-wire or the highway multi-disc beam of setting up of complete machine hanging beam; It is stressed to be converted to vertical shift mechanism during via hole, supports the anterior weight of bridge formation machine and along the bridge floor track travel.
