Description
Technical field
This utility model is related to shield machine and transports field, particularly relates to a kind of self-advancing type technique on shield machine's station-crossing dolly.
Background technology
Shield Machine misses the stop mode to take turns to walking and roller bearing slip two ways at present:
1. wheel is to walking manner: the shield machine track of laying walking in advance, mistake of shield machine insertion before reaching reception termination
Weld road wheel in shield main frame both sides in journey, after the completely upper walking track of shield main frame, provide pushing tow anti-using walking track
Power, hydraulic power unit and oil cylinder provide jacking force progressively to move forward, and shield main frame gets to the station and installs initiator before starting end head premise
Frame, gradually cuts off road wheel during shield machine originates frame.
Though this mode, is had the following disadvantages or defect to walking using wheel:
(1) shield machine reach receive termination before need to lay walking track in advance, to walking track laying position particularly
The requirement receiving end portion is higher；
(2) originate frame need to have bad luck in advance to originating terminal.
2nd, roller bearing sliding type: jacking bearing need to be welded in shield main frame both sides and install jacking during shield machine insertion
Oil cylinder, originates frame lower and need to lay steel plate in advance and slide for roller bearing, shield machine completely on originate main frame and beginning after frame
Send out welding machine frame to be integrated, using jacking cylinder by its jack-up, then originating bottom of the frame and putting between laying steel plate in advance
Put roller bearing, recycle hydraulic power unit and oil cylinder by main frame and to originate frame pushing tow forward, shield machine cuts off top after reaching originating terminal
Rise bearing, and frame will be originated and separate with shield main frame.
This mode has the disadvantage that
(1) shield main frame needs using hoist engine, steel plate to move forward after moving forward one and circulating, and there is larger potential safety hazard；
(2) the placement potential safety hazard of roller bearing is larger, and the randomness that roller bearing rolls is larger, and tuning is difficult；
There is general character in above two mode:
(1) welding capacity on shield main frame is big, and the intensity on main machine structure and wearability all have a certain degree of impact；
(2) preliminary preparation is more, and it is few that welding assembly recycles number of times, and welding position processes bad fragile portal
Sealing device, leads to portal closure difficult or even causes heavy losses；
(3) shield machine pipe bending cylinder, reaction support, steel plate etc. after the completion of stepping is both needed to manually have bad luck by jack, needs
Put into more personnel, and spend more time.
External shield mode mode of missing the stop with domestic shield at present of missing the stop is basically identical.
Utility model content
This utility model is to solve problems of the prior art, proposes a kind of self-advancing type technique on shield machine's station-crossing dolly.
The technical solution of the utility model is achieved in that
A kind of self-advancing type technique on shield machine's station-crossing dolly, its composition includes: originates frame, walking track, walking mechanism, flexible oil
Cylinder, rail clamping device, hydraulic power unit, described telescopic oil cylinder is driven by described hydraulic power unit, described originate frame and described rail clamping device peace
Put described walking track on, described originate frame be located at described rail clamping device front, described be originate frame aft with described
Telescopic oil cylinder front end connects, and described telescopic oil cylinder rear end is connected with described rail clamping device, and the described bottom of the frame that originates is provided with concave shaped
The walking mechanism mounting groove of formula, described walking mechanism is installed in described walking mechanism mounting groove by adpting flange, described row
Walk mechanism and described walking rail contact；It is additionally provided with shield machine support on the described top originating frame both sides.
Described telescopic oil cylinder rear and front end is passed through bearing pin one and is originated frame and described rail clamping device is connected with described respectively.
Described walking mechanism includes road wheel pair, and described road wheel is arranged in walker to by bearing pin two, described row
Walk wheel to match to described walking track.
The beneficial effects of the utility model are: this utility model does basis, shield machine reach stepping base using originating frame
This is completed using machinery, and manual work region is seen at scene only during walking track laying, hydraulic power unit operation and stepping
Shield etc., and personnel demand amount is less, decrease during missing the stop critical piece welding and cut off, top-pushing mechanism is manually had bad luck, originate
The operations such as the conversion of frame and road wheel pair, greatly reduce the duration of missing the stop, and decreases the usage frequency of hoist engine, roller bearing
Install, reduce the probability that the security incident during missing the stop occurs.
