Background technology
The retractor device of highway bridge mainly uses two kinds of technology, and one is barrier type modulus retractor device, and another kind is
Single support beam type retractor device, the above-below direction of its crossbeam is respectively arranged with multiple sliding support cushion block and compresses lip block, this two class
Accessory is rubber-like material, is deformed therewith under the long-term momentum effect of vehicle, and elastomeric material pushes away along with service life
Move and aging.In the prior art, if having sliding support cushion block or compression lip block to be damaged, need overall structure
All being replaced, its replacing construction length, maintenance cost cost are high.
Therefore, professional and technical personnel in the field's technical problem in the urgent need to address is exactly, the proposition how to innovate
A kind of device, avoids carrying out overall structure under damaged condition occurs in retractor device and all changes, and then reach minimizing time, fall
Low cost, purpose simple to operate.
Utility model content
For solving the problems referred to above, the lip block that the utility model discloses a kind of big displacement quantity bridge extension joint is changed
Device, including: 2 set jack, 2 set " U " type pull bars, fixing nut, polylith fix lip block, polylith sliding support cushion block,
Expansion joint displacement case, carry a load beam and crossbeam, the peristome of described 2 set " U " type pull bars is separately fixed at described by fixing nut
Carrying a load the two ends of beam, bending section is fixed on described crossbeam two ends, described 2 set jack be positioned at described in carry a load the both sides, bottom of beam,
Described crossbeam fixes lip block by described polylith, polylith sliding support cushion block is fixed on inside described expansion joint displacement case,
Described polylith is fixed lip block and is positioned at the above two ends of crossbeam, and described polylith sliding support cushion block is positioned at below crossbeam two
End.
Further, described 2 set " U " type pull bars are made up of reinforcing bar, and bar diameter is 22 millimeters.
Further, described polylith fixes lip block, polylith sliding support cushion block is made up of rubber.
Further, beam of carrying a load described in is made up of section steel material.
Compared with prior art, this utility model has the advantage that
This utility model uses the mode that jack and " U " type pull bar combine, and realizes mentioning horizontal stroke by jack-up beam of carrying a load
Beam, 2 jack can select a use, it is achieved that changes the purpose of a damage retractor device, it is to avoid crossbeam is whole
Mention, reduce the working time, improve work efficiency, saved replacement cost, improve social benefit.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing used in description of the prior art does one and introduces simply.
Fig. 1 is the structural representation of the supporting pad block changing device of a kind of big displacement quantity bridge extension joint of the present utility model
Figure.
In figure: 1 jack, 2 " U " type pull bar, 3 fix nut, 4 fix lip block, 5 sliding support cushion block, 6 expansion joints
Displacement case, 7 carry a load beam, 8 crossbeams.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is only a part of embodiment of this utility model rather than whole embodiments.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of this utility model protection.
As it is shown in figure 1, the supporting pad block changing device of a kind of big displacement quantity bridge extension joint.Including: 2 set jack 1,
2 set " U " type pull bars 2, fixing nut 3, polylith are fixed lip block 4, polylith sliding support cushion block 5, expansion joint displacement case 6, are chosen
Spreader beam 7 and crossbeam 8, the peristome of described 2 set " U " type pull bars 2 by fixing nut 3 be separately fixed at described in carry a load the two of beam 7
End, bending section is fixed on described crossbeam 8 two ends, described 2 set jack 1 be positioned at described in carry a load the both sides, bottom of beam 7, described crossbeam
8 fix lip block 4 by described polylith, that polylith sliding support cushion block 5 is fixed on described expansion joint displacement case 6 is internal, described
Polylith is fixed lip block 4 and is positioned at the above two ends of crossbeam 8, and described polylith sliding support cushion block 5 is positioned at below crossbeam 8 two
End.
Described 2 set " U " type pull bars 2 are made up of reinforcing bar, and bar diameter is 22 millimeters.
Described polylith fixes lip block 4, polylith sliding support cushion block 5 is made up of rubber.
