Abstract
The invention discloses a large-block girder section three-way aligning device which comprises a box girder rest pier which is arranged in a slide carriage. A horizontal adjustment jack is arranged between the slide carriage and the box girder rest pier. A vertical adjustment jack is arranged at the outside of the slide carriage. The device not only can carry out the three-way position adjustment of a steel box girder but also can ensure a pivot structure that a girder section slides freely in the plane. The large-block girder section three-way aligning device ensures the aligning precision, reduces the weight of equipment, simplifies the equipment operation, improves the utilization rate of the equipment and the facility and ensures the construction safety. After the adjustment of the position of one girder section, only the ordinary jack is required to be moved, so the work load is reduced greatly. In addition, after the large-block girder sections are welded and connected as a whole, when the large-block girder section is pushed and moved towards the river to be connected and jointed with a double-cantilever main girder, the rest pier can slide freely in the slide carriage, thereby realizing the multifunction. The device has simple and light structure, low requirement on the equipment, simple operation, safe usage, high aligning precision and multiple functions.
Description
Technical field
The invention belongs to building large-scale component apparatus for work, be specifically related to a kind of rackwork that the large-scale component locus is adjusted that is used for.
Background technology
Bridge large-block beam section, Sarasota beam section adopt the large-scale crane ship lifting, and are held on temporarily and deposit on the boom support.Large-block beam section length is long, and weight is big.For clear and definite beam section supporting condition, guarantee support force safety, carrying out elevation and plan-position when accurately adjusting, large-block beam section requires to adopt 4 supports.There is following difficulty during the positioning of beam section:
On the one hand, the safety of boats and ships and beam segment structure when hanging ships that transport in order to ensure large-block beam section, large-block beam section must level lifting, and level is held on and deposits on the boom support.Therefore, before connecting, each beam section coupling must carry out elevation and the plan-position is accurately adjusted, and linear to guarantee into bridge.
On the other hand, after the end bay large-block beam section is transposed piecemeal and is welded into integral body, when end bay closes up, need pushing tow end bay beam section integral body to the river side shifting, be connected with two cantilever girders and close up, large-block beam section must be free to slide along the strong point.Therefore, beam section fulcrum also should planar move freely, and moves and supporting structure safety to guarantee pushing tow.
Because the beam section is from great, it is narrow and small that support raises bit space, equipment difficult, and aligning precision and synchronism requirement height; There is not comparatively ideal way to address the above problem now as yet.
Summary of the invention
The object of the present invention is to provide a kind of large-block beam section that is applicable to realize the multifunction combined three-dimensional positioning apparatus that elevation and plan-position are accurately adjusted, to address the above problem.
Technical scheme of the present invention is: multifunction combined three-dimensional positioning apparatus, and it comprises case beam buttress, case beam buttress is shelved in the slide, establishes the horizontal adjustment jack between slide and the case beam buttress.
Described slide peripheral hardware is vertically adjusted jack.
Described slide end face is provided with corrosion resistant plate, and slide plate is established in case beam buttress bottom surface.
This device can carry out the position adjustment of steel case beam three-dimensional, can guarantee the fulcrum structure that the beam section planar is free to slide again.When guaranteeing aligning precision, alleviate weight of equipment, simplifying operation of equipment, raising installations and facilities utilization rate, guarantee construction safety.After finishing a beam fragment position adjustment, only need mobile ordinary jack, workload significantly reduces.And, after large-block beam section welding is linked to be integral body, moves to river side integral pushing and to be connected with pair cantilever girders when closing up, buttress can be free to slide in slide, has realized multipurpose.This apparatus structure is simple, light and handy, the equipment requirement is low, easy and simple to handle, safe in utilization, aligning precision is high, function is many.

The specific embodiment
As shown in Figure 1, slide 1 is a rectangle frame, and rectangle frame four side guards 12 are provided with spacing gripper shoe 13, and the end face of the slide in the rectangle frame is provided with corrosion resistant plate 2.Shelve case beam buttress 3 in the rectangle frame of slide 1, the bottom surface that case beam buttress 3 contacts with corrosion resistant plate 2 is provided with slide plate 4, and slide plate is the tetrafluoro slide plate.Establish the horizontal adjustment jack between slide and the case beam buttress; Establish cushion block between slide and horizontal adjustment jack or horizontal adjustment jack and the case beam buttress.Be provided with cushion block 6 between the baffle plate 12 of concrete slide and the horizontal adjustment jack 5.Horizontal adjustment jack 5 can be located between any baffle plate of four side guards 12 and the case beam buttress (as shown in Figure 2).Vertically adjust jack 7 (as shown in Figure 3) at slide 1 peripheral hardware.
Combined type three-dimensional positioning apparatus use principle is: the large-block beam section level is shelved on 4 buttresses (as shown in Figure 4), and two one of case beam buttresses are formed being provided with, and establish 2 groups at least.Each buttress bottom is provided with the tetrafluoro slide plate, is bearing in the slide that is provided with corrosion resistant plate, by level jack is set buttress is moved in slide in slide, realizes beam section plan-position is adjusted.At the other vertical absolute altitude of vertical jack adjustment beam section that is provided with of buttress, realize beam section elevation is adjusted.When closing up pushing tow, buttress is free to slide in slide, realizes that girder is whole mobile.
Combined type three-dimensional positioning apparatus using method is: before the large-block beam section lifting,, slide is installed in beam section position of the fulcrum, then buttress is arranged in the slide by measurement and positioning, and its position in slide of temporary limit, crane barge lifting beam section is shelved on the buttress.Large-block beam section is progressively adjusted its position according to the method for first elevation, back plane.At first, arrange vertical jack in the buttress bilateral symmetry, adjust beam section elevation synchronously, after elevation was adjusted to the right place, it was real to insert metal mat in the gap of pushing up with buttress at the bottom of the beam section, unloads vertical jack and finishes the elevation adjustment.Then, arrange level jack between slide baffle plate and buttress, the top is moved buttress and is moved in slide, finishes the plan-position adjustment.Repeated measurement and adjustment beam section control point elevation and plan-position meet the demands up to precision.
