After three sections track bridges rises flushed, safety pin stretched out between 4 track bridges of stage casing movable rail Biodge device, the longitudinal register of two siding track bridges before and after strengthening; 4 stage casing track bridge safety pins of movable rail bridge ground both sides, stage casing stretch out, to strengthen the location of stage casing movable rail bridge; Respectively stretch out two front and back bridge safety pins in the basis of repair line both sides trapped orbit end, strengthen the location of forward and backward two siding track bridges.Therefore the track bridge has 12 place's positioning and locking devices.Track bridge positioning and locking device is made up of reducing motor, leading screw screw, location shank etc.
Install on the stage casing movable rail bridge 23 a pair of frame supports wheel to replace device (39) be used for change wheel to the time, mid-rail bridge lowering or hoisting gear rises and utilizes this device can hold framework.The frame supports wheel adopts steel plate to be welded into the rectangle rigid structure to replacing device.
Cross moving track (5) is used to provide the movable rail bridge to shift out passage, because front and back section track bridge all can be laterally from traveling, so equipment has two groups of totally four cross moving tracks.Every cross moving track is divided into two sections, deposits on the line lowering or hoisting gear at bogie for one section, and another section is a canned paragraph, extends to bogie from track bridge lowering or hoisting gear and deposits the line lowering or hoisting gear.When being in sustained height for two sections, the movable rail bridge can traveling on cross moving track, runs to bogie from repair line and deposits line or deposit line from bogie and run to repair line.
Bogie is deposited the line lowering or hoisting gear and is installed in bogie and deposits the line place, when the movable rail bridge runs to bogie and deposits line end, is used for the movable rail bridge is promoted to and fixedly deposits trajectory and flush.Bogie is deposited the line lowering or hoisting gear and is comprised lifting body (40) and lifting device (42), lifting body is the plate frame structure of steel plate welding, front and back are equipped with the cross moving track section, the centre is equipped with long rails section (41), when the movable rail bridge run to be used for when depositing line end with the movable rail bridge on long rails link into an integrated entity.Lifting device has two covers, is positioned at both sides, lifting body front and back, adopts motor-driven to promote, and comprises framework (43), drive motors (44), leading screw (46), screw (45), positioning and locking device etc.The location shrinking device comprises alignment pin (48) and drive motors (49) composition.
Control system adopts industrial control computer and PLC to control, and is used for bogie or wheel are carried out automatically and manually control changing operation, and carries out signal indication, interlocking and data management etc.
Car body unwheeling device be used to change bogie or the wheel to the time, car body is held.Car body unwheeling device is made up of two side portal frames and moving body carriage two parts.Portal frame is installed in the track both sides that bogie is changed station, every side portal frame and vehicle to be made as center, station track to portal frame inboard width near gauge be 1800mm.Different in order to adapt to different automobile types unwheeling point, the car body carriage can move continuously along portal frame vertical equity direction in the 4200mm scope; Driving the unwheeling pin by motor-driven leading screw screw can be to the flexible automatically 500mm of car body direction, utilize leading screw, screw latching characteristics, can guarantee the self-locking of unwheeling pin optional position, the car body carriage can promote 300mm under screw drives, the car body carriage is mainly used in when changing bogie car body one end is held.
All be equipped with the vertical rail of standard on the movable rail bridge, be connected with the repair line trapped orbit when being used for equipment and not working, vehicle can normally be moved by repair line, can carry out traveling during work and drive carrying out lifting action, and then finish bogie or wheel changing operation by lowering or hoisting gear.The movable rail bridge is formed by three sections, and two sections of front and back can be driven by lowering or hoisting gear carries out lifting and can carry out traversingly simultaneously from traveling, and interlude is driven by lowering or hoisting gear only and carries out lifting.Motor-driven are adopted in the front and back traversing travelings of two sections track bridges.
Bogie or wheel are as follows to changing process step:
(1) bogie stream is changed process step and is: unwheeling device unwheeling → disassemble bogie and car body coupling components → track bridge be whole to promote (hoisting depth is that track bridge orbital plane is a little more than the trapped orbit face) → safety pin withdrawals → track bridge integral body decline → preceding, the traveling of back segment track bridge synchronous horizontal shifts out → and preceding, the traveling of back segment track bridge is deposited line lowering or hoisting gear → deposit line lowering or hoisting gear lifting → replacing bogie (shift out old bogie, move into new bogie) → deposit the line lowering or hoisting gear to descend → preceding to bogie, the traveling of back segment track bridge moves into that repair line → track bridge is whole to be promoted (hoisting depth is that track bridge orbital plane is a little more than the trapped orbit face) → safety pin and stretches out → and the track bridge is whole to descend (the track bridge drops to safety pin and contacts fully with the track bridge) → and installation bogie and car body coupling components → unwheeling carriage decline → unwheeling pin regain → finish replacing.
(2) the one-sided wheel changed process step to (being assumed to be front-wheel) and be: unwheeling device unwheeling → stage casing track bridge liftings → frame supports wheel is held framework → disassemble bogie to shift out with front-wheel coupling components → horizontal traveling of leading portion track bridge decline → leading portion track bridge → leading portion track bridge traveling and is deposited the wheel change of line lowering or hoisting gear → deposit line lowering or hoisting gear lifting → more → deposit to bogie line lowering or hoisting gear decline → leading portion track bridge traveling immigration repair line → leading portion track bridge promotes → install bogie and replacing is regained → finished to front-wheel coupling components → unwheeling carriage decline → unwheeling pin replacing device.
(3) bilateral wheel to changing process step is: unwheeling device unwheeling → stage casing track bridge liftings → frame supports wheel to replace device hold framework → disassemble bogie and before, trailing wheel coupling components → preceding, back segment track bridge decline → preceding, the horizontal traveling of back segment track bridge shifts out → and preceding, the traveling of back segment track bridge deposits line lowering or hoisting gear → deposit line lowering or hoisting gear to bogie and promotes → wheel change → deposit the line lowering or hoisting gear to descend → preceding more, back segment track bridge traveling immigration repair line → preceding, back segment track bridge lifting → installation bogie with before, replacing is regained → finished to trailing wheel coupling components → unwheeling carriage decline → unwheeling pin.
