Be provided with the connection groove corresponding with described lift-bolt at described roadbed accurate adjustment frame.
Be provided with the slideway corresponding with described roadbed accurate adjustment frame at described roadbed backing plate.
Roadbed backing plate in the utility model has the function that supports roadbed accurate adjustment frame and protection roadbed supporting layer, and roadbed accurate adjustment frame has the dual-use function of supporting rail framed bent and fixing and locking.The utility model can adapt to various roadbeds highway section, makes the easier for installation of the roadbed section of track, and accurate adjustment efficient can improve more than 30%.The utility model is simple in structure, and processing and fabricating is convenient, and in light weight, rigidity is big, and is easy and simple to handle, in use can effectively protect the roadbed supporting layer.Use of the present utility model can reduce labour intensity, improves efficiency of construction, shortens construction period.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises locking adjusting rod 1, regulates double-screw bolt 2, connects parts such as bearing pin 3, roadbed accurate adjustment frame 4, roadbed backing plate 5, accurate adjustment bolt 6, lift-bolt 7 and section of track frame 8.
Roadbed accurate adjustment frame 4 adopts the lead frame structures, comprises the through hole that a screwed hole corresponding with accurate adjustment bolt 6, are corresponding with being connected bearing pin 3, and a detent corresponding with lift-bolt 7.The side riser of roadbed accurate adjustment frame 4 is made of the monoblock steel plate, and the rigidity of roadbed accurate adjustment frame 4 is increased greatly.Cross-under has the top to the accurate adjustment bolt 6 of roadbed backing plate 5 on the side riser of roadbed accurate adjustment frame 4, is used for the lateral attitude of buffer rail framed bent 8.
End face at roadbed accurate adjustment frame 4 is connected to lift-bolt 7, is connected to section of track frame 8 in the upper end of lift-bolt 7, and lift-bolt 7 can be regulated vertical height of section of track frame 8.On the outer end of section of track frame 8 and roadbed accurate adjustment frame 4, be hinged with and regulate 2, two of double-screw bolts to regulate double-screw bolt 2 be positive and negative button screw rod by being connected bearing pin 3 respectively, locking on the adjusting rod 1 from the two ends cross-under respectively.Locking adjusting rod 1 is thick walled steel tube, and its two ends are provided with the positive and negative button nut corresponding with regulating double-screw bolt 2.
By rotating accurate adjustment bolt 6, can make roadbed accurate adjustment frame 4 drive section of track frame 8 and horizontally slip at roadbed backing plate 5, reach the purpose of accurate adjustment section of track frame.Locking adjusting rod 1 is regulated double-screw bolt 2 by two and is flexibly connected with section of track frame 8 and roadbed accurate adjustment frame 4 between section of track frame 8 and roadbed accurate adjustment frame 4.Rotation lock adjusting rod 1 can change the protruded length of regulating double-screw bolt 2, thereby reaches the purpose of fixing and locking section of track frame.
Locking adjusting rod 1 in the utility model and roadbed accurate adjustment frame 4 and roadbed backing plate 5 can flexible combination, and be easy for installation, to adapt to different construction requirements.
Roadbed accurate adjustment frame 4, roadbed backing plate 5 are the critical piece of accurate adjustment section of track frame with accurate adjustment bolt 6, lock adjusting rod 1, regulate double-screw bolt 2 and be connected bearing pin 3 to be the critical piece of fixing and locking section of track frame after the accurate adjustment.Roadbed backing plate 5 is placed on the roadbed outer, is supporting roadbed accurate adjustment frame 4, regulates accurate adjustment bolt 6, makes roadbed accurate adjustment frame 4 drive lift-bolts 7 move left and right, realize section of track rail to move left and right; Locking adjusting rod 1 after accurate adjustment is finished, with section of track frame 8 fixing and lockings, can prevent that section of track frame is offset when concreting by regulating double-screw bolt 2 and being connected bearing pin 3 and being connected with roadbed accurate adjustment frame 4 with section of track frame 8.
