Fig. 2 is the knot for the double-block type ballastless track bridge base cross form positioner that the utility model embodiment provides
Structure schematic diagram two.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in figs. 1 and 2, a kind of double-block type ballastless track bridge base cross form positioner, for cross form 6
Positioning, drift 1, connecting rod 2 are included in structure, heightens bolt 3, positioning fixture 4 and bolt 5；Described positioning fixture 4
Including U-shaped 41, two pieces of location-plates 42 of frame, screw shell 43 and adjusting nut 44；U-shaped frame 41 can be directly suitable using size
Channel-section steel；Two pieces of location-plates 42 are welded in side-lower in U-shaped frame 41, are symmetrical arranged, for limiting the spacing of two pieces of cross forms 6,
Bolt 5 is located at the U-shaped biside plate of frame 41, and both sides inwardly clamp cross form 6；The biside plate of specific channel-section steel is respectively provided with two
Screwed hole, bolt 5 have four, one side two.The inner side of cross form 6 abuts location-plate 42, and bolt 5 is from lateral surface
It is screwed into and clamps cross form 6；Avoid loosening, using the locking positioning bolt 5 of locking nut 7.
Described screw shell 43, which extends vertically through, is welded in the U-shaped center of frame 41, heightens bolt 3 and screws in screw shell from top
43 lower ends connect connecting rod 2, can weld or be threadedly coupled, and the lower end of connecting rod 2 connection drift 1, can weld or be threadedly coupled,
Bolt 3 is heightened to lock by adjusting nut 44 and screw shell 43；Two inclined-planes of described drift 1 and two pieces of cross forms 6
Anchor point contacts and supports cross form 6.
This example realizes that the height of whole positioner is adjusted by screw shell 43 and adjusting nut 44, and bolt is heightened in operation
3 realize the relative movement of connecting rod 2 and positioning fixture 4.The anchor point of described cross form 6 has everywhere, and bolt 3 is heightened in operation
The construction requirement of double-block type ballastless track bridge straightway and superrelation on curve section can be realized simultaneously, when straightway is constructed, the positioning
Device can be adjusted to the sustained height of cross form 6 by heightening bolt 3；When superrelation on curve section is constructed, the positioner passes through tune
High bolt 3 is adjusted to four kinds of height of the gradual change of cross form 6.
The described section lower end size of drift 1 is less than 100cm；Upper end size is more than 100cm.To ensure between cross form 6
Requirement away from 100mm, specifically, the described section lower end size of drift 1 is 90cm；Upper end size is 120cm.
This example, not only ensure that the support strength of cross form bottom, while also achieve the jail of bridge bedplate spacing
By fixation.Cross form length is generally 2800mm, and its longitudinal direction can set 4 anchor points every 700mm, required round steel, section bar, determine
The materials such as position bolt are easily obtained and processed, and perform flexible and convenient, accurate positioning, the total quality and outward appearance that bedplate pours are equal
Good construction effect is achieved, there is good promotional value.
The positioner is easy to operate, accurate positioning, cost are controllable, high construction efficiency, and only unit in charge of construction has not saved greatly
The cost of manufacture of amount, and the pouring quality of double-block type ballastless track bridge bedplate is effectively guaranteed, and has good
Use range and promotional value.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
