The working process and principle of the present embodiment are as follows：
Using manually or mechanically ballast between the sleeper of bad sleeper both sides has been cleared up, bolt is marked with machine oil on the outside of bad sleeper
Good, engineering truck traction track car is run during to bad sleeper, the image information of cmos image sensor collection, is known by figure
Other system automatic identification, makes engineering truck be parked in the cmos image sensor position coaxial with machine oil mark bolt, rail-lifting equipment position
Directly between the sleeper of bad sleeper right side, as shown in figure 1, oil pump is started working, hydraulic oil starts double output shaft hydraulic motor
Rotate forward, drive left-handed screw and right handed screw forward direction synchronous axial system, left-handed nut and right-handed nut is promoted respectively and it
Two connected square tube shape telescopic arms are synchronously stretched out, and two square sliders are slided two square tube shape telescopic arm endoporus upper surfaces respectively
It is dynamic, it is to avoid left-handed screw and right handed screw bear moment of flexure, make two pairs of swing rods of symmetrically arranged two parallelogram lindages relative
In entablature dorsad synchronous hunting, lowering or hoisting gear entrusts rail-lifting equipment decline, by first laser displacement sensor its with
The displacement signal of entablature controls the lifting to drive double output shaft hydraulic motor and spiral rotary actuator to work, when carrying rail
Device is dropped to when carrying cylinder of rail cylinder body gusset upper surface and coplanar rail lower surface, and double output shaft hydraulic motor stops positive
Rotate, hydraulic oil makes spiral rotary actuator start to rotate forward, drive opposite crank to rotate forward, transport two connecting rods
It is dynamic, promote I-shaped tubular travelling arm synchronously to stretch out respectively, I-shaped tubular travelling arm entrusts two and carries cylinder of rail and moves out respectively,
When cylinder of rail cylinder body is carried with rail lower flange contacts side surfaces, carry cylinder of rail cylinder body gusset upper surface and contacted with below rail,
Second spiral rotary actuator stops rotating forward, and hydraulic oil makes to carry cylinder of rail piston rod and stretches out, and cylinder of rail is carried when being fixed on
The fagging contact railway roadbed ballast of piston rod and after being compacted into, with constantly stretching out for cylinder of rail piston rod is carried, carries cylinder of rail
Cylinder body is entrusted gusset and is moved upwards, makes rail jack-up, position shown in Fig. 2, and the middle position of solenoid directional control valve makes to propose cylinder of rail pressurize；
After manually or mechanically pulling out bad sleeper, pushing new sleeper, hydraulic oil makes to carry cylinder of rail piston rod and starts to retract,
Its piston rod hauls fagging and moves upwards, and original position is dropped down onto under rail, and hydraulic oil makes spiral rotary actuator start reversely to turn
It is dynamic, drive opposite crank to rotate backward, make two link motions, pull I-shaped tubular travelling arm synchronously to retract respectively, I-shaped cylinder
Shape travelling arm entrusts two and carries cylinder of rail and inwardly moves respectively, is contacted when carrying cylinder of rail cylinder body and being disengaged with rail lower flange side
When, spiral rotary actuator stops rotating backward；
Hydraulic oil makes double output shaft hydraulic motor start to rotate backward, and drives left-handed screw and right handed screw reverse sync to turn
Dynamic, the two square tube shape telescopic arms connected with its are synchronous to retract left-handed nut and right-handed nut is pulled respectively, makes to be symmetrical arranged
Two the two of parallelogram lindage pairs of swing rods relative to the opposite synchronous hunting of entablature, lowering or hoisting gear entrust rail-lifting equipment rising
To position shown in Fig. 1, double output shaft hydraulic motor stops rotating backward, and oil pump is stopped, and carries sleeper and terminates.
Symmetrically arranged two parallelogram lindages of lowering or hoisting gear, make square tube shape telescopic arm parallel all the time with sill, with
Adapt to straight line and the sleeper nut assembly and disassembly work of curved rail length section.
