The association of adjacent plate, adjacent tensioning mechanism is interleave plate synchronization implementation when locking is with unblock, when entering to give tensioning contact association but
Independently working.
It is placed in the plate on stretching bed seat in several tensioning equipment/mechanisms and forms a connected plate group, the plate
The both ends plate of group is connected with A action tanks 1 and B action tanks 27 respectively, and the rod end of two oil cylinders is fixed with oil cylinder and cut somebody's hair
24, being cut somebody's hair with oil cylinder on corresponding plate side has push rod 25, and the two is equally connected in a manner of being engaged.
Shown in Figure 10, according to III type track plates design standard, there are two row's tension reinforcing steel bars of longitudinal direction track plates axial direction side, right with this
Should, hold each tensioning equipment on stretching bed seat to be formed by two longitudinal directions tensioning oil cylinder group arranged side by side.Stretch board 6 in figure,
Draw oil cylinder 7, the bottom of plate 26 that second stretch board 30, the second oil cylinder group 31 and the second plate 32 be correspondingly installed, while also pair
The the second tension rod chain joint answered.
During work, the transportation trolley of bearing track board mold is moved in place on the inside of tensioning equipment and by track plates along track
Mould is positioned on positioning support.Now, railway plate die height strictly matches with the height of end/side tensioning equipment, and error exists
In scope of design.Hydraulic station works, end/side feed cylinder（115、122）, the traversing oil cylinder in end/side（113、118）Work, end/side
Oil cylinder in place（114、123）Work by setup program, both sides tensioning equipment is in place.
Under original state, tension rod is combined in place with tension reinforcing steel bar, and the external screw thread of tension rod is rotary with abnormity nut（Locking screw
It is female）；There are two external tooth form boss 16 the cylindrical 180 degree position of abnormity nut；Now the geared sleeve rotation in tensioning retaining mechanism stops
Stay position and do not know, boss 22 is in random site, and reliable docking condition can not be met, it is necessary to be accurately positioned.First, hydraulic pressure
The low pressure low speed rotation of motor 3, motor driven gear wheel 12 also low speed rotation and drive locking gear 14 and the low speed rotation of geared sleeve 13,
Tension rod chain joint 15 moves forward in the axial direction simultaneously and slowly close to geared sleeve 13, when close to geared sleeve, boss 22 is with stopping
The dynamic collision of screw 21 occlusion, is horizontal the locking groove 18 of geared sleeve 13；Stretching bed seat moves in the axial direction, makes to open
Pull bar 17 is sequentially entered in the rod aperture of geared sleeve 13 and tension rod chain joint 15, the external tooth form boss 16 of abnormity nut on tension rod
It is engaged with the collision of locking groove 18.
Now, the piston rod of A action tanks 1 is stretching state, and the piston rod of B action tanks 27 is contraction state, tension rod 17
Enter through the heavy caliber hole position of plate 26 in tension rod chain joint.When locking operation, the rod chamber of A action tanks 1 and rodless cavity pressure
Dynamic balance, piston rod position are in quick condition, and the piston rod of B action tanks 27 stretches out, and drive oil cylinder to cut somebody's hair and 24 translations and promote
Plate group synchronous horizontal displacement, tension rod 17 enter locking position, as illustrated in figures 4-5 state.
Tensioning oil cylinder 7 works, and tension rod chain joint 15, which retreats, initially enters tensile state, while hydraulic motor works, and drives
Dynamic locking gear and geared sleeve rotate, and drive abnormity nut to be locked simultaneously to tension reinforcing steel bar.The hydraulic motor and tensioning
Oil cylinder shares hydraulic station, when tensioning in place when, hydraulic motor is also stopped while tensioning oil cylinder is stopped.Tensioning and lock
Tightly complete simultaneously.
When unlocking operation, the rod chamber of B action tanks 8 and rodless cavity pressure balance, piston rod position are in quick condition, A
The piston rod of action tank 1 stretches out, and drives oil cylinder to cut somebody's hair and promotes plate group synchronous backward displacement, it is big that tension rod 17, which enters solution lock-bit,
Aperture location.
