Between, overall structure is rectangular plate-like structure, meanwhile, flat surface 6 from left to right direction median surface Yu notch from left to right
Median surface coincides, and is provided with screw hole on the lower end surface of the flat surface 6, in order to the installation of X-type lifting device 5, it is preferable that
The good concreting of 6 bearing capacity of flat surface forms, and can guarantee that rotary bogie derailing beam is bearing single track column
It caused by vehicle when load, will not be damaged, and then avoid the generation of security risk, improve the rotary bogie derailing beam
Safety and reliability.
As shown in Fig. 1 Fig. 2, which includes derailing beam 3 and rotary rail 7.Wherein the setting of derailing beam 3 exists
6 upper surface of flat surface is from left to right on median surface position, which is rectangular rail beam, and rounding is made in two sides
The position of processing, the corresponding left track beam 1 and right track beam 2 is equipped with the round cambered surface of indent, can be along left rail convenient for derailing beam 3
Road beam 1 and right track beam 2 rotate.Preferably, which is special steel beam, and length is slightly longer than bogie, on the one hand guarantees
Bogie can all be run on derailing beam 3, be convenient for disassembly maintenance and on the other hand improved by using special steel
The intensity of the derailing beam 3 will not be damaged with meeting when bearing the load of train to be repaired, and it is de- to reduce the rotary bogie
There are the probability of security risk for beam-and-rail, improve the safety and reliability of rotary bogie derailing beam.
Meanwhile the following end face center in 3 lower end surface of derailing beam is that center of circle bilateral symmetry is provided with circular groove, this is arc-shaped
The radius of groove is identical as the radius of rotary rail 7, and is provided with idler wheel on the upper surface of slot, and in order to derail, beam 3 prolongs rotation
Rail 7 of transduceing slides.3 front end face of derailing beam is matched with 1 right end of left track beam, before the rear end face and right track beam 2 of the beam 3 that derails
End face matches, and left side and right side are also concordant with left track beam 1, the left and right end face of right track beam 2, and rotary at this
When bogie derailing beam rises to maximum height, derailing 3 upper surface of beam and track girder upper surface are located at same level.And at this
When rotary bogie derailing beam minimizes adjustable height, derailing 3 top surface of beam and bogie cradle top surface are located at same level
Face, and can smoothly remove derailing beam 3, it ensure that the feasibility of the rotary bogie derailing beam.7 center pair of rotary rail
Claim be arranged on 6 upper surface of flat surface, using 6 twelve-hour direction of flat surface as zero degree, clockwise direction zero degree to 90 degree with
It is provided with arc-shaped rail within the scope of 180 degree to 270 degree, the guide rail radius and derailing 3 lower end surface of beam are arc-shaped
Groove radius is identical, and the overall structure is the guide rail of section convex shape, for providing guide slide for derailing beam 3.It completes
After the dismounting of bogie and the decline of automatic lifting structure, so that derailing beam 3 is prolonged the selection of rotary rail 7 by way of promotion and move
It is dynamic, complete the rotation to bogie.
A kind of rotary bogie derailing beam of straddle-type monorail of the embodiment of the present invention, working principle and its specific implementation step
It is rapid as follows:
Step 1: when the maintenance for thering is train to be repaired to need to carry out bogie, should first check guarantee derailing 3 upper surface of beam first
It is located at same level with track girder upper surface, later stops train to be repaired to designated position, guarantees that its bogie structure is complete
It rests on derailing beam 3.Staff opens train skirtboard to be repaired and supports the weight of train using jack, then flows according to the rules
Journey dismantles bogie, separates bogie with car body.
Step 2:, should by the control panel control inside automatic lifting structure after bogie separates completion with car body
Automatic lifting structure drops to minimum elevation, is located at the upper surface of derailing beam 3 and the upper surface of bogie bracket 8 same
On horizontal plane.Later, derailing beam 3 is prolonged rotary rail 7 to push, makes derail beam 3 and the alignment of bogie bracket 8, to make it possible to
Bogie is smoothly smoothly pushed, should ensure that derailing beam 3 is correctly docked with bogie bracket 8 at this time, and fix bogie
Bracket 8 guarantees that the two position is motionless in moving process.Bogie can be moved to bogie bracket 8.
Step 3: after the completion of the maintenance to bogie, by after repairing bogie or new bogie be placed on bogie branch
It on frame 8, is aligned with derailing beam 3, bogie is moved on derailing beam 3.The beam 3 that will derail again is pushed to along guide rail 7 and track girder
Be in line state.It is again turned on power switch, manipulation automatic lifting structure rises to maximum height.Power switch is then shut off,
Disconnect external power supply.On the car body by bogie installation, wheel davit is unloaded.So far the dismounting of bogie and upkeep operation are complete
At.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not used to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
Within protection scope of the present invention.
