The specific embodiment

Positioning machine is a mechanical-electrical-hydraulic integration equipment.Whole positioning machine structure comprises the pilot unit that two special section bars of usefulness that guide roll is housed are made, and respectively there is a cantilever camber beam each unit, with the height of hydraulic efficiency governing cantilever camber beam, on the cantilever camber beam swivel bearing is installed.Swivel bearing is coupled together and strengthen rigidity with a vertical continuous supporting structure.On vertically continuous carrying structure, have four support brackets at a distance of four meters, be used for supporting fragment-free track slab.The non-fragment orbit member is used hydraulic clamp equally.For adapting to the member of different-thickness, equipment has the interval supporting of quick-detach soon.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is erected on two bracing frames 10, and bracing frame 10 fixedly secures on the basis.Welding two guide rails 11 on each bracing frame 10, roller 21 walkings of cantilever camber beam 20 are in guide rail 11.A telescopic oil cylinder 12 all is housed on each bracing frame 10, and telescopic oil cylinder 12 is hinged with cantilever camber beam 20, and like this, oil cylinder 12 just drives cantilever camber beam 20 knee-actions.Turning device mainly is made of crossbeam 30, upset motor 31, motor reducer 32 and fixing device 40.Main portion in the middle of the crossbeam 30 is by the weldment of section bar and steel plate welding, is welding assembling fixing device 40 on it.Motor reducer permanent seat 22 is welded on the cantilever camber beam 20, and motor reducer 32 is fixed thereon.Crossbeam 30 two ends are connecting firmly two axles by flange, and one of them 34 links to each other with the motor reducer 32 of turning device, motor reducer 32 by be contained in 35 li self-aligning roller bearings 36 of bearing seat, axle 34 drives crossbeam weldment and the fixing devices on it 40.Motor reducer 32 is provided with converter plant, easily governing speed.Crossbeam 30 other ends are equipped with another minor axis 37 and bearing seat 35, bearing 36, and the bearing seat 35 at two ends all is fixed on the cantilever camber beam 20.The supporting leg 33 of fixing device 40 is welded on the crossbeam, and supporting leg 33 is equipped with the lock shaft 41 of free-running fit, and lock shaft 41 connects together by key and fork 42, and two axle sleeves 43 are equipped with at lock shaft 41 two ends, has guaranteed that the rotation of lock shaft 41 is flexible.The pinching end of lock shaft 41 is equipped with adjusts piece 44, adjusts piece 44 and can adjust the height that fixing device clamps.Adjust the packaged wheel of adjustment 45 that has, adjust wheel 45 and can closely compress fragment-free track slab.The rotation of whole fixing device 40 is driven by hydraulic ram 46, and hydraulic ram 46 1 ends are fixed on the crossbeam, and an end and fork 42 are hinged.When needs chucking track plate, just promote oil cylinder 46 and make fixing device 40 grip rails guidance tapes, when needs unclamp the track plate, just rotate fixing device 40 and unclamp the track plate.

Working process of the present utility model is: crossbeam 30 rises to the highest station by the cantilever camber beam 20 of walking in the guide rail 11 of bracing frame 10, and crane is placed into fragment-free track slab on the crossbeam 30, by the fixing device 40 grip rails guidance tapes of hydraulic ram 46 drivings.The variable-frequency motor reductor 32 of crossbeam 30 rotation usefulness drives crossbeam 30 rotations that clamp fragment-free track slab, can divide the speed governing of speed two-stage, guarantees that the track plate is parked in parallel ground-surface position.Roller 21 on the cantilever camber beam 20 walks in the guide rail 11 on the bracing frame 10, and hydraulic ram 46 drives walking cantilever camber beams 20, can bear the weight of crossbeam 30 and fragment-free track slab, and fragment-free track slab is placed on the delivery track.Then, fixing device 40 is opened, and turning device rises to terminal location again.After turning device soared, turning device just can reverse, from newly carrying out upset work.Like this, positioning machine has just been realized the work of upset.
