Abstract

A PC track girder die block trolley consists of fixed die blocks, movable die blocks and roller boxes; the fixed die block is a Braille-shaped one, the two shoulders are disposed with movable die blocks, the movable die block consists of several rectangle modules equal to the shoulder height; four roller boxes are disposed at the bottom of the fixed die block. The utility model, with the movable die blocks, the length of the track girder die block trolley could be adjusted; in order to save field and investment, the trolley is disposed with roller boxes which could rotate 90 degrees locally to ensure the die block trolley could run on the vertical plane track; the structure of the model is totally made of steel framework which has comparatively high rigidity and intensity.

Description

PC track girder bed die chassis

Technical field

The utility model relates to the required bed die chassis of cast light rail PC track girder, belongs to the Machining Technology field.

Background technology

In the prior art, domestic light rail technology is just at the early-stage, and PC track girder process technology is one of technological difficulties of cross-saddle single-track traffic design.Correlation technique and product all need to introduce from states such as Japan at present, and foreign technology not only costs an arm and a leg, and have complex structure, maintenance cost problem of higher.As the PC side template of a cover processing light rail track girder only, just need spend 250,000 dollars at least, bed die chassis price is more then higher.Simultaneously, because process need change storehouse over to and deposit beam through pricking links such as muscle, cast and steam curing again; Therefore, the bed die chassis needs the mobile corresponding flow process that changes over to mould.The production domesticization of light rail technology is that domestic one of ordinary skill in the art have problem to be solved.

The content of utility model

At the prior art above shortcomings, the purpose of this utility model provide a kind of reasonable in design, cost is low, cooperate the bed die chassis of PC side template processing light rail track girder.

The purpose of this utility model is achieved in that PC track girder bed die chassis, by fixedly bed die, movable bed die, roller box are formed; Fixedly bed die is the type shape, is movably equipped with movable bed die on two shoulder lengths, and movable bed die is made up of the rectangular block that several equate with shoulder height; Roller box is a fourth officer, is located at the fixedly bottom of bed die.

The long 9m that is at least in the type top of described fixedly bed die.

Described roller box comprises upper box, lower box, steel wheel and vertical axis; Upper box is connected with fixing bed die by connecting axle, and steel wheel is loaded on the lower box, and by the vertical axis location, lower box can rotate around vertical axis, is designed to the mating surface with emboss pit between the upper and lower casing contact-making surface between upper box and the lower box.

Compared to existing technology, the utlity model has following advantage:

1, owing to designed movable bed die, the bed die adjustable length of track girder then, bed die chassis total length reaches 25 meters, can pour into a mould the track girder of 14-22 rice respectively;

2, for saving space and investing, bogie wheels has designed and can spend the following roller box that rotates in original place 90, guarantees that the bed die chassis moves on vertical planar tracks;

3, all adopt steel skeleton construction, have higher rigidity and intensity, bed die chassis top surface plane degree≤2mm.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the upward view of Fig. 1.

Fig. 4 is the structural representation of roller box.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model PC track girder bed die chassis is by fixedly bed die 1, movable bed die 2, roller box 3 are formed; Fixedly bed die 1 is the type shape; Movable bed die 2 is made up of the rectangular block that several equate with shoulder height.Power section is with existing chassis technology.Among the figure, the 8th, rail, the 10th, track girder, the 11st, end mould, the 12nd, side form.As shown in Figure 3, roller box 3 is located at the fixedly bottom of bed die 1 for fourth officer.

As shown in Figure 4, roller box 3 comprises upper box 4, lower box 5, steel wheel 6 and vertical axis 7; Upper box 4 is connected with fixing bed die 1 by connecting pin 9, steel wheel 6 is loaded on the lower box 5, and by vertical axis 7 location, lower box can rotate around vertical axis between upper box 4 and the lower box 5, be designed to mating surface between the upper and lower casing contact-making surface, with the stability that guarantees to turn to emboss pit.

Its operation principle is: 1, PC track girder bed die chassis is pushed " bundle muscle " operation position, increase or what of the bed die that takes in sail according to the length of required track girder; 2, chassis is pushed " cast " operation position, fixedly side form 12 and end mould 11 are poured into a mould on chassis then; 3, chassis is pushed " steam curing " operation position and carry out maintenance; 4, changing storehouse behind the initial tensioning again over to strides and deposits beam.

Consider saving construction site rationally, produce usually to stride and promptly prick muscle, cast and the design of steam curing operation in a straight line that chassis reenters storehouse through 90 degree turnings and strides.Can spend the following roller box that rotates in original place 90 because bogie wheels has designed, guarantee that the bed die chassis moves, and not only saves space but also saved investment on vertical planar tracks.
