Abstract
A TBM (Tunnel Boring Machine) stepping device for an open cut lining section of an inclined shaft comprises an originating bracket, vertical hydraulic jacks, longitudinal moving guide rails, horizontal hydraulic jacks and a traction device, wherein the originating bracket is fixedly connected with a TBM host; two counterforce points are welded on each of two sides outside the housing of the TBM host, and the vertical hydraulic jacks are respectively mounted on the two sides; the longitudinal moving guide rails are mounted at the lower part of the originating bracket, counterforce points are mounted at the rear parts of the longitudinal moving guide rails, and the two horizontal hydraulic jacks are mounted on the longitudinal moving guide rails in a bilaterally symmetrical manner; and the traction device is connected with the longitudinal moving guide rails. By adopting the TBM stepping device, TBM equipment and the originating bracket can step successfully in a finite space, and the operation is simple and feasible.
Description
Technical field:
The utility model belongs to a kind of construction implement, particularly a kind of inclined shaft open cut lining cutting section TBM step device.
Background technology:
The TBM development machine integrates brill, digs, protects, can effectively realize the growing up factory operation of constructing tunnel, state-of-the-art large-scale synthesis constructing tunnel equipment in the world, representing the highest level of international tunnel construction technology, be widely used in the engineering fields such as traffic, water power, mine, municipal administration, national defence in the world.
Carries out in the flat slope section more than the at present TBM stepping, stepping is a new problem that faces on the slope of the confined space, and simultaneously, in the past TBM equipment stepping all is first in the position of starting, and then the stepping main frame carries out TBM and starts to the bracket locations that starts.
Summary of the invention:
The purpose of this utility model just is to provide a kind of inclined shaft open cut lining cutting section TBM step device, and this device can be realized TBM equipment and the simultaneously successful stepping on the slope of the confined space of carriage of starting, and simple to operate, easy row.
As above design, the technical solution of the utility model is: a kind of inclined shaft open cut lining cutting section TBM step device is characterized in that: comprise the carriage that starts, vertical hydraulic jack, vertical shift guide rail, horizontal hydraulic pressure jack and draw-gear; Start carriage and TBM main frame is affixed, respectively welds two counter-force points in TBM host shell both sides external, and vertical hydraulic jack is installed respectively; The vertical shift guide rails assembling is installed the counter-force point in the carriage bottom of starting at vertical shift guide rail rear portion, and two horizontal hydraulic pressure jack bilateral symmetry are installed on the vertical shift guide rail; Draw-gear is connected with the vertical shift guide rail.
Above-mentioned draw-gear is comprised of hoist engine and fixed pulley, and fixed pulley is fixed on originating terminal, and is connected with hoist engine.
The utility model utilize TBM main frame steel plate and the friction factor between carriage and vertical shift guide rail of starting less than vertical shift guide rail and concrete friction factor, and the friction factor between steel and the steel is greater than the percentage of the gradient, be that frictional force is greater than the principle of the power of rubbing down, therefore, the utility model can be realized TBM equipment and the simultaneously successful stepping on the slope of the confined space of carriage of starting, and simple, the easy row that operates.
Description of drawings:
Fig. 1 is the utility model drawing in side sectional elevation;
Fig. 2 is top view of the present utility model.
Among the figure: 1, TBM main frame; 2, the carriage that starts; 3, vertical shift guide rail; 4, guide-rail coupling member; 5, vertical hydraulic jack; 6, horizontal hydraulic pressure jack; 7, hoist engine; 8, fixed pulley.
The specific embodiment:
As shown in the figure: a kind of inclined shaft open cut lining cutting section TBM step device is comprised of the carriage 2 that starts, vertical hydraulic jack 5, vertical shift guide rail 3, horizontal hydraulic pressure jack 6 and draw-gear.Start carriage and TBM main frame 1 is affixed, respectively welds two counter-force points in TBM host shell both sides external, and vertical hydraulic jack is installed respectively; The vertical shift guide rails assembling is installed the counter-force point in the carriage bottom of starting at vertical shift guide rail rear portion, and two horizontal hydraulic pressure jack bilateral symmetry are installed on the vertical shift guide rail, and connects by guide-rail coupling member 4.Above-mentioned draw-gear is comprised of hoist engine and fixed pulley, and fixed pulley is fixed on originating terminal, and is connected with hoist engine.
This device is used for open cut liner structure internal diameter 8.2m, TBM diameter 7.64m, and when downward grades was the inclined shaft of 6 degree, its implementation step was as follows:
1, TBM main frame 1 and the carriage 2 that starts are connected and fixed, respectively weld two counter-force points in shield shell both sides external, and vertical hydraulic jack 5 is installed respectively.
2, utilize vertical hydraulic jack with 1 jacking of TBM main frame after, vertical shift guide rail 3 is installed, the vertical hydraulic jack 5 of vertical shift guide rail 3 rear withdrawals in place, the rear portion that TBM main frame 1 and the carriage 2 that starts are fallen vertical shift guide rail 3 in the bottom of the carriage 2 that starts.
3, the counter-force point is installed at vertical shift guide rail rear portion, is adopted two horizontal hydraulic pressure jack 6 pushing tow carriage 2 that starts that is symmetrically arranged simultaneously, main frame 1 and the carriage 2 that starts are shifted onto the front end of vertical shift guide rail 3.
4, again start vertical hydraulic jack 5 will start carriage 2 and main frame 1 jack-up, the fixed pulley 8 traction vertical shift guide rails 3 that utilize hoist engine 7 and be fixed on originating terminal move ahead.
5,3 vertical shifts of vertical shift guide rail fall vertical hydraulic jack 6 after in place again, and start carriage and main frame of the method pushing tow above adopting arrives the front end of vertical shift guide rail, goes round and begins again, until the carriage that starts arrives originating location.
Can realize TBM equipment and the simultaneously successful stepping on the slope of the confined space of carriage of starting by this device.
