Description
Technical field
The utility model relates to a kind of rail adjustment device, specifically high ferro roadbed freeboard section non-fragment orbit adjusting device.
Background technology
High ferro roadbed freeboard section ballastless track structure height is changeless 815mm.When roadbed exists superrelation on curve, roadbed supporting bed is tilted on subgrade bed, section of track accurate adjustment all operations on the face that this tilts of non-fragment orbit.When buffer rail is to adjuster, affect by angle of inclination, the section of track can produce lateral displacement in adjustment process, during concreting, also can produce lateral displacement when being subject to the external force that concrete is toppled over, vibrating head vibrates.Center line, the elevation of non-fragment orbit all can have greatly changed, and need readjust, thus affect precise velocity.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of high ferro roadbed freeboard section non-fragment orbit adjusting device.
The utility model for achieving the above object, be achieved through the following technical solutions: high ferro roadbed freeboard section non-fragment orbit adjusting device, comprise fixed head, mounting-fixing base on fixed head, holder is offered vertical spacing hole, in spacing hole, leading screw is set, the lower end of leading screw is arranged on fixed head by bearing, holder arranges limiting plate, bottom surface and the holder of limiting plate touch, chute is offered in limiting plate one end, the limiting plate other end connects the bottom of non-fragment orbit template, leading screw is positioned at chute, chute both sides sidewall arranges screw thread, chute matches with leading screw, wheel disc is installed in the bottom of leading screw, cavity offered by holder, cavity communicates with spacing hole, wheel disc is positioned at cavity, wheel disc is connected with power set by driving-belt.
For realizing the purpose of this utility model further, can also by the following technical solutions: described limiting plate middle top surface installs hinge seat, limiting plate is by one end of hinge seat hinge support bar, and the other end of support bar is threaded stay pipe, and stay pipe connects the top of non-fragment orbit template.
The utility model has the advantage of: in the utility model, the mode adopting leading screw to coordinate with the chute on limiting plate, by rotational lead screw, can control the transverse shifting of limiting plate, thus can scheduling regulate after giving birth to lateral displacement in-orbit, avoid affecting precise velocity.The utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.

Detailed description of the invention
High ferro roadbed freeboard section non-fragment orbit adjusting device, as shown in Figure 2, comprise fixed head 1, fixed head 1 fixedly mounts on the ground.Mounting-fixing base 2 on fixed head 1, holder 2 is offered vertical spacing hole 3, arranges leading screw 4 in spacing hole 3.Spacing hole 3 plays the effect spacing to leading screw 4, prevents the stressed generation of leading screw 4 from tilting.The lower end of leading screw 4 is arranged on fixed head 1 by bearing, holder 2 is arranged limiting plate 5, bottom surface and the holder 2 of limiting plate 5 touch, chute 6 is offered in limiting plate 5 one end, limiting plate 5 other end connects the bottom of non-fragment orbit template, leading screw 4 is positioned at chute 6, chute 6 both sides sidewall arranges screw thread, chute 6 matches with leading screw 4, wheel disc 9 is installed in the bottom of leading screw 4, and holder 2 is offered cavity 10, cavity 10 communicates with spacing hole 3, wheel disc 9 is positioned at cavity 10, and wheel disc 9 is connected with power set by driving-belt.The mode that this structure adopts leading screw 4 to coordinate with the chute 6 on limiting plate 5, control power set and driving-belt drive wheel disc 9 to rotate, and control leading screw 4 and rotate, make limiting plate 5 produce transverse shifting, thus regulated by the lateral displacement of non-fragment orbit template to the section of track, avoid affecting precise velocity.
Because limiting plate 5 is connected to the bottom of non-fragment orbit template, during in order to avoid adjustment lateral displacement, non-fragment orbit template bottom produces deformation.Described limiting plate 5 middle top surface installs hinge seat, and limiting plate 5 is by one end of hinge seat hinge support bar 7, and the other end of support bar 7 is threaded stay pipe 8, and stay pipe 8 connects the top of non-fragment orbit template.This structure makes support bar 7 hinge on limiting plate 5, the convenient angle regulating support bar 7 and limiting plate 5, and support bar 7 is threaded with stay pipe 8, distance each other can be regulated, thus the link position of stay pipe 8 and non-fragment orbit template can be regulated, make non-fragment orbit template uniform force, avoid the stressed excessive generation deformation in the bottom of non-fragment orbit template.
In order to the lateral displacement of auxiliary adjustment non-fragment orbit, inside non-fragment orbit template, several base plate 11 is evenly set along track, base plate 11 fixedly mounts on the ground, base plate 11 is installed junction plate 12, junction plate 12 offers through hole, screw rod 13 is set in through hole, screw rod 13 coordinates installation first nut 14 and the second nut 15, first nut 14 and the second nut 15 lay respectively at junction plate 12 both sides and all touch with junction plate 12, through-hole diameter on junction plate 12 is less than the diameter of the first nut 14 and the second nut 15, the horizontal frame bar connecting of screw rod 13 and non-fragment orbit.This structure can pass through the position of adjustment first nut 14 and the second nut 15, and adjusting screw(rod) 13 relative to the position of base plate 11, thus can regulate the lateral displacement of non-fragment orbit by the horizontal frame reinforcing bar of push-and-pull non-fragment orbit.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The technology contents of the not detailed description of the utility model is known technology.
