Description
Technical field
This utility model relates to tunneling boring tunneling equipment technical field, particularly relates to a kind of double mode shield interchanged type pressure-bearing next door.
Background technology
In prior art, tunneling boring tunneling equipment generally can only take single-mode to carry out tunnel piercing, such as can only adopt earth pressure balance pattern or hard rock pattern.Earth pressure balance pattern and hard rock pattern are two kinds of distinct tunnel piercing patterns, for earth pressure balance pattern, excavation face is dregs or dregs mud mixture, in plastic relaxation shape, equipment can be produced the pressure of about 0.3MPa～0.5MPa, for ensureing the safety of the properly functioning and staff of tunneling equipment, pressure reduction between excavation storehouse and no-dig technique storehouse just blocks by the pressure-bearing next door of setting on tunneling equipment, so that dregs sends excavation storehouse by controlling the intrinsic pressure conveying worm in soil storehouse；For hard rock pattern, excavation face is fragility from solidity rock, and the pressure-bearing next door of tunneling equipment will not be produced pressure by himself stability structure, and rubble dregs can pass through belt feeder and be carried out excavating storehouse.But the working environment of tunneling boring tunneling equipment is sufficiently complex, its excavation face met with will not be all dregs or dregs mud mixture, without being all that fragility is from solidity rock, in most cases, these two kinds of excavation faces can constantly be alternately present, now just need the change according to tunnel piercing pattern to change different tunneling boring tunneling equipments, be unfavorable for the raising of drivage efficiency, be more added significantly to constructing tunnel cost.
Summary of the invention
The technical problems to be solved in the utility model is in that, the tunnel piercing pattern existed for tunneling boring tunneling equipment in prior art is single, be unfavorable for the raising of drivage efficiency and the drawbacks described above that constructing tunnel cost is high, it is provided that a kind of tunneling boring tunneling equipment that is beneficial to can realize freely switching, being favorably improved drivage efficiency and reduce the double mode shield interchanged type pressure-bearing next door of construction cost between earth pressure balance pattern and hard rock pattern.
This utility model is for solving above-mentioned technical problem, and its technical scheme adopted is as follows:
A kind of double mode shield interchanged type pressure-bearing next door, including fixed mount, pressure-bearing next door cover plate and pressure-bearing next door driving mechanism；

Further, above-mentioned main traction cylinder is main drawing oil cylinder.Compared with cylinder, because oil cylinder volume is little, power is big, therefore adopt main drawing oil cylinder as main traction cylinder, on the one hand, substantial amounts of installing space can be saved, on the other hand, constant motion and variable motion can be done, the degree of freedom of transmission is higher, and transmission stability is better, disclosure satisfy that the needs that shield machine advances under waiting steric requirements.
As a kind of improvement to double mode shield interchanged type pressure-bearing next door described in the utility model, also include the closure assemblies being arranged on above-mentioned fixed mount top.When tunneling boring tunneling equipment adopts hard rock pattern to carry out tunnel piercing, pressure-bearing next door cover plate and fixed mount are in the state separated, now, a space is there is between this pressure-bearing next door cover plate and fixed mount, dregs or dregs mud mixture or fragility will be fallen in this space from solidity rock, so equipment itself or staff can be caused damage or injury, and this closure assemblies in case of emergency can form umbrella protection structure in the top position of fixed mount with pressure-bearing next door cover plate, thus avoiding dregs or dregs mud mixture or fragility to fall into from solidity rock equipment itself or staff cause damage or injury, not only facilitate the service life extending tunneling boring tunneling equipment, and safety coefficient is high.
Further, above-mentioned closure assemblies includes capping and for driving the capping traction cylinder of this capping, and this capping traction cylinder is arranged on the top of above-mentioned fixed mount.
When tunneling boring tunneling equipment adopts hard rock pattern to carry out tunnel piercing; namely when pressure-bearing next door cover plate and fixed mount are in the state separated; at this in emergency circumstances, capping can form umbrella protection structure under the driving of capping traction cylinder in the top position of fixed mount with pressure-bearing next door cover plate.
Further, above-mentioned capping traction cylinder is capping drawing oil cylinder.Same as above, adopt capping drawing oil cylinder as capping traction cylinder, be possible not only to save substantial amounts of installing space, and make capping traction cylinder can do constant motion and variable motion, the degree of freedom of its transmission is higher, and transmission stability is better, it is possible to meet the needs that shield machine advances.
In technical scheme described in the utility model, the bottom inside of above-mentioned pressure-bearing next door cover plate is provided with sealing ring, when described double mode shield interchanged type pressure-bearing next door is installed together with shield body, being provided with of this sealing ring helps strengthen the sealing property being connected between pressure-bearing next door cover plate and shield body, particularly as follows: when tunneling boring tunneling equipment adopts earth pressure balance pattern to carry out tunnel piercing, this sealing ring can also realize the seal isolation inside excavation storehouse and shield body.
It addition, in technical scheme described in the utility model, all it is not specifically noted, all can by adopting the conventional means in this area realize the technical program.
Therefore, the double mode shield interchanged type pressure-bearing next door that this utility model provides is beneficial to tunneling boring tunneling equipment and can realize freely switching between earth pressure balance pattern and hard rock pattern, is favorably improved drivage efficiency, moreover it is possible to reduce construction cost.
