Background technique
Steel support shaft force servo system in foundation pit enclosure structure supporting, site operation equipment is generally by numerical control pumping plant
It is formed with branch fastener two parts, the core component of numerical control pumping plant is control centre and power output source, is generally placed upon on foundation pit side；
Branch fastener and bracing members are erected in the building enclosure of foundation pit both ends after being bolted and design specified position, for going along with sb. to guard him
Structure applies axle power, to limit the horizontal displacement of building enclosure in Excavation Process.The power of branch fastener is pumped from numerical control
It stands, the two is connected by oil pipe with cable, and oil pipe is the transmission medium of power, and cable is used to transmit data-signal.
A usual numerical control pumping plant can control eight branch fasteners, and power output source is one, to the axis of each fastener
Power load and unloading can only control one by one, can not carry out simultaneously.It is connected, is being applied with hydraulic oil pipe between pumping plant and each fastener
Oil pipe is easily destroyed so as to cause axial force of the supports failure during work.When equipment is installed and is removed, transfers equipment and need
Reclosing oil pipe, live mud impurity enters hydraulic device easily also so as to cause thrashing, therefore equipment needs are regularly maintained.
Numerical control pumping plant needs workbench, can occupy certain construction space, and the position put will consider not influencing the same of site operation
When also to guarantee hydraulic oil pipe Reasonable Arrangement, reduce oil pipe route.
Summary of the invention
In order to overcome the drawbacks of the prior art, a kind of install convenient is provided, transfers and flexible excavates safeguard, the present invention
Disclose a kind of integrated full-automatic branch fastener assembly and its application method.
The present invention reaches goal of the invention by following technical solution:

When add unloading, it is also more flexible to transfer management, is independent of each other；Pass through integration, it is no longer necessary to which construction site is that numerical control pumping plant stays
If position, also eliminates the mixed and disorderly oil pipe in scene and lay, it is more convenient to install；Complete equipment realizes totally-enclosed design, is propping up
There is no the disconnection of fluid pressure line and connection when fastener is transferred, the risk that impurity is mixed into system is avoided, safety is big
It is big to improve；Complete equipment eliminates individual large-sized numerical control pumping plant, realizes complete distribution, implements drop corresponding to maintenance cost
It is low.
Electric-control system and pumping plant are integrated in branch fastener frame by the present invention, the full-automatic branch fastener assembly of being integrally formed,
Greatly reduce tubing length, therefore oil pump capacity also accordingly reduces, the space in braced frame can original size not
Increase power and electrical system on the basis of change, forms the integration of equipment.
The invention has the following beneficial effects:
Compared with existing axle power servo techniques, integrated full-automatic branch fastener assembly that the present invention uses, it is no longer necessary to construct
Scene is stayed for numerical control pumping plant and sets position, also eliminates the mixed and disorderly oil pipe in scene and lays, it is more convenient to install；Due to support system one
Body can be avoided the risk for being mixed into impurity in system when branch fastener is transferred, greatly improve safety；The present invention can
Unloading is realized between each branch fastener while being added, is independent of each other, it is more flexible to transfer management.
