It due to this feature, spreads line apparatus and is advanced on the horizontal level by self-propelled pedestal 10, such as when in ditch
When slot is nearby advanced, the position of manipulator and groove is adjusted by the rotation of cantilever 20.
For this purpose, pipeline storage device 30 is matched by sports metering device 32 and fixed device 31 according to feasible modification
Conjunction mode connects.In detail, the sports metering device 32 can be pivoted to the fixed device 31, sports metering dress with both ends
32 rotations are set, the rotation of pipeline is driven.
Sports metering device 32 is specially the line wheel of both ends protrusion, the lug boss of line wheel and fixed 31 inside kissing of device
It closes.
For the revolving speed of sports metering device 32, unpowered design can be both used, dynamic design can also be used, hanged
Arm 20 and pipeline junction are equipped with actuator, prevent from influencing construction precision, preferably hydraulic because pipeline and cantilever 20 are generated and rubbed
Actuator.
When pipeline storage device 30 on the ground when, the actuator can be used for that beam 20 is made to do stretching motion.
In order to allow the pilot line during lay-up operation of cantilever 20, and therefore make the pipeline along the axis of pipeline
Sliding, the cantilever point can be rotated centered on node of the cantilever with the self-propelled pedestal within the scope of 0-360 °,
The cockpit, dynamical system, cantilever, pipeline storage device are uniformly distributed on the self-propelled pedestal, and the cantilever is with certain
One speed rotated within the scope of 0-360 ° and the manipulator pilot line on the cantilever to required pipeline installation groove just
Top, the dynamical system drive the self-propelled pedestal to move ahead along track and control the pipeline storage device with identical speed
Degree overflows pipeline, and the route that the self-propelled pedestal is advanced is parallel with the route of pipe installation.
