Description
Technical field
This utility model is related to a kind of small-sized TBM rock rippers, more particularly to a kind of small-sized TBM rock rippers are quick
Initiator device.
Background technology
In tunneler TBM construction fields, pre- cavity preparation is excavated using blasting procedure typically, is provided for rock ripper and is originated
Support, long construction period, construction costs is high, there is potential safety hazard, to environment, the present invention proposes a kind of small-sized TBM
The quick initiator device of rock ripper, realizes small-sized TBM rock outs function safety, quick, low cost and originates, be to excavate directly
The Tunnel Engineering that footpath is little, length is short provides technical support.
The content of the invention
In order to overcome the disadvantages mentioned above that TBM rock rippers are originated in TBM work progress in prior art, this utility model
There is provided a kind of quick initiator device of small-sized TBM rock rippers, formed by steel plate welding processing, it is characterised in that include：Circle
The top of ring-type, the lower base being made up of two wedges and base plate, wedge pass through to be welded to connect with base plate, wedge
Inner side is arc-shaped, and isometrical with the annulus at top, and the circular arc on the inside of wedge is connected by vertical steel plate with bottom, top
Flange is welded with lower base junction, and by high strength exploitation, top is provided with hoisting port, top and lower base
Side is provided with reinforcement, and base plate is provided with anchor pole fixing hole.
According to other side of the present utility model, there is provided a kind of quick using aforesaid small-sized TBM rock rippers
The method originated by initiator device, comprises the following steps：
1）Originating terminal tunnel portal is removed using pneumatic pick artificial chisel；
2）Carry out it is pre- repair place, provide smooth, firm place to install quick initiator device；
3）Using crane by the quick initiator device of piecemeal be transported to it is prefabricated originate field, quickly begun according to erection sequence
Transmitting apparatus are assembled, and are fixed quick initiator device with anchor pole；
4）Before being originated, the geological condition of rock mass in tunnel is analyzed, determine rock mass comprcssive strength and
Infiltration coefficient；
5）Small-sized TBM rock rippers are transported and are installed in quick initiator device using crane and specific purpose tool, made
Small-sized TBM rock rippers are against hole driving face；Tunnel portal is sealed using rubber curtain plate, small-sized TBM rocks pick
Rubber curtain top of the plate is entered hole by the housing for entering machine；
6）Start small-sized TBM rock rippers, now propelling cylinder is in contraction state, start stretching oil cylinder, boots will be supportted
Support on quick initiator device, withdraw rear support, make the weight of whole rock ripper all fall shield and support boots on, shield and
The stretching system that support boots are constituted provides enough reaction of bearings for the startup of propelling cylinder and supports reaction torque；
7）Start the main driving of cutterhead and belt slag-tapping system, the main drive belt moving knife disc spins of cutterhead；Start propulsion system, push away
Enter oil cylinder pushing cutterhead shield, cutterhead shield promotes cutterhead；Under the collective effect of the main driving of cutterhead and propulsion system, cutterhead knife
Tool carries out broken rock, and drives whole small-sized TBM rock rippers to push ahead；Fractured rock is transported to hole by belt slag-tapping system
Outer process；
8）Propelling cylinder is fully extended, completes the excavation operation of a stroke, and main driving of cutterhead stops, and cutterhead stops broken
Rock, belt slag-tapping system stop；
9）Rear support oil cylinder stretches out, and rear support, main girder and shield provide support force, propelling cylinder oil return for stretching system
Mouth oil-feed, propelling cylinder are retracted, and after stretching system moves to commitment positions under the drive of propelling cylinder, stretching oil cylinder stretches out,
Prepare next stroke action；
10）Small-sized TBM rock rippers repeat above-mentioned 6）To 9）Action, into cavern is excavated, when rock hole wall can be with
After the support reaction of small-sized TBM rock rippers is provided, quick initiator device is removed, small-sized TBM rock rippers start formal pick
Enter, complete to originate.
The quick initiator device operation principle of small-sized TBM rock rippers of the present invention is as follows：
Using crane by the quick initiator device of piecemeal be transported to it is prefabricated originate field, can using prefabricated section made by steel plate
Recycle, it is convenient and swift, it is not easy to damage, and the weight of small-sized TBM can be carried, dress is quickly originated according to erection sequence
Assembling is put, and quick initiator device is fixed with anchor pole；Quick initiator device provides enough anti-for small-sized TBM rock rippers
Active force and reaction torque；Small-sized TBM rock rippers start driving, when rock hole wall can provide small-sized TBM rocks pick
After entering the support reaction of machine, quick initiator device is removed, small-sized TBM rock rippers start formal driving, complete to originate.
Compared with prior art, using this utility model can realize small-sized TBM rock rippers it is safe, quick, it is low into
Originally originate, technical support is provided for the Tunnel Engineering that digging diameter is little, length is short.
