Cast anchor hole, switch hole independence lining trolley is only provided with 4 single-wheels, and without hoofing part mechanism, main outer power is pulled on rail walks.

2, positioning principle

Cast anchor after hole, switch hole independence lining trolley go to precalculated position under external force traction, operation lifting mechanism place mechanic jacks makes longeron drive bracket, bow member, template assembly to move along tunnel lateral direction and make template transverse shifting in place, then positive operation center line adjustment place mechanic jacks makes chassis rise, reverse operating mechanic jacks makes chassis decline under self gravitation condition, arrives specified altitude assignment.Regulate mechanical helical screw to carry out support fixing, prevent door frame, bow member and template deformation.

3, lining cutting principle is widened in side change

Cast anchor hole, switch hole independence lining trolley when lining cutting is widened in side change, only need remove and widen side and connect everywhere, this side is made to cast anchor hole beam template (driving this lateral bracket, bow member) outwards movement under external force, move into place rear with steady pin locking and connect with bolt connecting, reach the object that lining cutting is widened in side change.

Chassis operating process following (see Fig. 5):

1. chassis traction is in place

Lining trolley drives to appointment mileage by 4 single-wheels under external force traction on rail.

2. cast anchor hole, switch hole bow member is widened

Change cast anchor hole, switch hole assembly as required.

3. chassis location

Making upper longeron drive bracket, bow member, template assembly to move along tunnel lateral direction by regulating mechanic jacks makes template laterally in place.Then regulate the mechanic jacks at lifting mechanism place to control chassis and be elevated to position, make to need to widen side under external force to cast anchor hole beam template (driving this lateral bracket, bow member) outwards movement, move into place rear steady pin to lock, regulate mechanical screw rod to carry out reinforcing to chassis to support, prevent chassis to be out of shape.

4. installation form assembly

Link with U-shaped between template and connect, template is connected with bow member bolt, and for guaranteeing Surface Quality of Concrete, end head formwork must apply on request.

5. tear the end head formwork demoulding open

Unscrew helical screw, take down pin, take down helical screw, tear the end head formwork demoulding open.

6. trolley running

Make to need to widen the side hole beam template (driving this lateral bracket, bow member) that casts anchor under external force and move inward retraction, move into place rear steady pin and lock.Then regulate the mechanic jacks at lifting mechanism place that chassis is declined, to be casted anchor hole (switch hole) by external force traction to next place.

7. go to the 2nd step

So far a working cycles is completed.
