Specific embodiment
Referring to the drawings, a kind of Open TBM composite slide-plate formula stepping mechanism, including lift cylinder group 1, support base 2, step
Enter push action cylinder 3, upper slide 4, lower skateboard 5, wear-resisting copper coin 6, cylinder lever connecting rod 7, raceway plate 8, roll stepping support 9, wherein,
Support seat 2 is welded together with TBM shield A, provides clamping force by lift cylinder group 1.Lift cylinder group 1 is two-way cylinder, with
Stepping mechanism toward engineering typically adopts one-way cylinder, due to the protection of backhaul no pressure, so that lift cylinder is damaged.And this reality
Effectively avoid the problem damaged during oil cylinder backhaul with the two-way cylinder of new employing, simultaneously compared with one-way cylinder backhaul
Faster, the lifting cycle is shorter, and performance is more stable for speed.Stepping push action cylinder one end is fixed on TBM shield A, and the other end is solid
It is scheduled on upper slide 4, provides thrust for TBM stepping, be provided with wear-resisting copper coin 6 between upper slide 4 and lower skateboard 5, improve slide plate
Service life.Lower skateboard 5 is divided into left and right two halves, is bolted, and is easy to assembly and disassembly.Slide plate passes through height with raceway plate 8
The cylinder lever connecting rod 7 of intensity body structure connects, and connected mode is hinged.Rail is welded with raceway plate, rolls stepping during stepping and prop up
Frame 9 is rolled on rail by roller, reduces frictional resistance.Roll stepping support 9 column upper flanges to pass through with TBM saddletree B
Bolt connection, support body column adopts shears oblique pull to support, and increased the stability of support.Rolling stepping support 9 laid inside has
Platform, is easy to place necessary instrument and equipment during equipment stepping, such as electric welding machine, oxygen-acetylene gas cylinder, stepping mechanism hydraulic pump
Stand, storage tank etc..It is divided into four steps during TBM stepping：One when being original state, at lift cylinder group 1 and stepping push action cylinder 3
In the state of recovery, support base 2 and girder tail support C to reclaim, and prepare stepping.Two is the propulsion phase：Stepping push action cylinder 3 drives
TBM 2 meters of stepping forward, reach a stroke.Three is driving phase：After stepping push action cylinder 3 reaches range, in lifting
In the presence of oil cylinder group 1, support base 2 falls and stretching tunnel bottom, and girder tail supports C to stretch out simultaneously, stretching tunnel bottom.Four
It is to change step section：When relying on fixing with the frictional force of tunnel in the presence of TBM supports C and support base 2 in tail, stepping thrust oil
Cylinder 3 withdraws, and drives slide plate and rolling stepping support 9 to withdraw.When stepping push action cylinder 3 is fully retracted, in lift cylinder group 1
The lower support base 2 of effect lifts, and TBM girder tail supports C to reclaim simultaneously, completes a cycle of operation, prepares next step cycle.
Its operation principle is that support base 2 is welded together with TBM shield A, rolls stepping support 9 and passes through with TBM saddletree B
Flange bolt connects.Slide plate is connected by the cylinder lever connecting rod 7 of high-strength sealed box typed structure with rolling stepping support 9.Stepping
When thrust provided by stepping push action cylinder 3, the lift cylinder group 1 being made up of two-way cylinder is to provide reliable support during stepping
Clamp force.
It is further discussed below this utility model with reference to embodiment：
The stepping mechanism that engineering project generally adopted in the past has full wheel group type and two kinds of structures of scooter type.Full wheel group type design
Not only high cost, in-site installation is difficult, ground intensity is had high demands, and 4 rail 3 trajectory need to be laid in advance the walking of wheel group is provided,
Even need external force traction and increase braking function etc., often some conflict with construction plan in Practical Project for this.Scooter type
In recent years using more, structure is relatively easy, advantage of lower cost, but there is TBM in actual applications and promote mainly two kinds of shapes of oil cylinder
The selection of state, one is that oil cylinder is in open state, and two is that oil cylinder is in servo-actuated state.According to uneasy during first kind of way stepping
Oil cylinder promoted mainly by dress, and after whole machine stepping puts in place, in tunnel, to promote mainly oil cylinder very difficult for assembling.Promote mainly according to the second way
Oil cylinder need to be servo-actuated, and promoting mainly cylinder pipe needs to remove, thus oil cylinder cannot lubricate, oil cylinder is caused oil-free abrasion and inside dirty
Dye.The trend that this utility model requires according to current engineering middle and long distance stepping, summarizes the pluses and minuses of conventional stepping mechanism, not
Dismounting TBM solves the problems, such as on the premise of promoting mainly oil cylinder to promote mainly the abrasion of oil cylinder oil-free and internal contamination, saves the duration and becomes
This, will be widely used in tunneler field.
