Abstract
The utility model discloses an open type TBM direct side discharging concrete injecting system which comprises a concrete conveying pump system and a concrete tank truck. The concrete conveying pump system comprises a concrete conveying pump and a concrete conveying pump power control device, the concrete conveying pump and the concrete conveying pump power control device are arranged on a TBM backup trolley in a separating mode, the power control device is arranged on a platform of the TBM backup trolley, the concrete conveying pump is also arranged on the platform of the TBM backup trolley and is arranged at a lower position, and the discharge port of the concrete tank truck is located on the inclined upward side of a receiving hopper of the concrete conveying pump. According to the open type TBM direct side discharging concrete injecting system, the concrete conveying pump is separated from the concrete conveying pump power control device and is arranged at the lower position; a stirring shaft of the concrete tank truck is changed into the mode that half spirals left and half spirals right; the side discharge port is directly aligned to the receiving hopper of the concrete conveying pump, concrete materials can be discharged into the receiving hopper of the concrete conveying pump directly, a middle material transfer device is not needed, and the delay of the TBM excavating work caused by the concrete injection work is reduced greatly.
Description
Technical field
The utility model relates to full section rock tunnel development machine (TBM) technique of design and construction field, especially a kind of direct side discharging concrete spraying system of arranging on supporting chassis after TBM.
Background technology
Open TBM and thereafter corollary system generally all design arrangement have concrete spraying system, to realize TBM driving, time can carry out the concrete spraying support operation of tunnel.TBM concrete spraying system is comprised of concrete conveyance pumping system, spraying machinery hand system and concrete tank, and jet robot is as far as possible near main frame afterbody layout, and drug delivery pump system is arranged on the manipulator rear supporting chassis of certain joint below.
Current drug delivery pump system is with the delivery pump of receiving hopper and power control unit is integrated is arranged on rear supporting chassis, and material receiving port is positioned at rear supporting platform higher position like this.The discharging opening of concrete tank is in its front portion, after the tank car of current like this discharging opening puts in place, often need to promote or lateral displacement, and discharge opening of tank truck position is lower, concrete material directly can not be discharged into delivery pump receiving hopper, often need pass on pump or belt conveyor in the middle of additional that concrete material is transferred to hopper.Like this, often there will be because of tank car displacement, middle grass-hopper fault or hardening of concrete and clear up and incur loss through delay concrete injection, and then make TBM stop driving wait, reduced TBM driving speed.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly without centre, turns materials device and concrete tank also without the Open TBM side discharging concrete spraying system of displacement.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the direct side discharging of a kind of Open TBM concrete spraying system, and it comprises concrete conveyance pumping system, spraying machinery hand system and concrete tank, described concrete conveyance pumping system comprises concrete pump and concrete pump power control unit, its key technology is: described concrete pump and concrete pump power control unit apart arrangement on supporting chassis after TBM, described concrete pump power control unit is installed on the platform of supporting chassis after TBM, described concrete pump is also installed on the platform of supporting chassis after TBM, and compare low level installs with concrete pump power control unit, the discharging opening of described concrete tank is positioned at the oblique upper of the receiving hopper of concrete pump, paddle on the shaft of described concrete tank half be left-hand screw setting, second half is right-hand screw setting, the discharging opening of this concrete tank is positioned at the medial side upper/lower positions of shaft.
Preferably, the support bar that above-mentioned paddle is welded on shaft by inclination forms with the ring-like stirring piece of fan that is positioned at support bar front end.
Adopt the beneficial effect that technique scheme produces to be: in the utility model with the delivery pump of receiving hopper and low position separated with its power control unit after TBM on supporting chassis; Shaft, side outlet that concrete tank changes left and right spiral half and half into by original one direction spiral shaft, the design of front discharging opening design.After tractor traction concrete tank puts in place like this, the directly oblique aligned beneath delivery pump receiving hopper of side discharging opening, can directly be discharged into concrete material delivery pump receiving hopper.Like this, without centre, turn materials device, tank car, also without displacement, greatly reduces due to the delay of concrete spraying operation to TBM excavation operation.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model is comprised of concrete pump 1, concrete tank 4, concrete pump power control unit 2 and spraying machinery hand system.Shaft 11 in concrete tank 4 is half and half left and right helical design, discharging opening 7 sides.Concrete pump 1 and the separated setting of concrete pump power control unit 2, and concrete pump 1 lower position on rear supporting chassis 3 is arranged (compared with low level, being to compare with concrete pump power control unit 2).After concrete tank 4 tractions put in place, open side discharging opening 7, concrete material tiltedly below is directly discharged into concrete pump receiving hopper 8, and operation concrete pump power control unit 2, is just pumped to concrete material jet robot by pipeline and carries out concrete spraying operation.
Referring to accompanying drawing 3 and accompanying drawing 4, shaft 11 is provided with the stirring liquid of half left-hand screw type and the paddle of half right-hand screw type, left and right spiral respectively occupies half of shaft 11, can make like this concrete be expressed to be positioned at the side discharging opening 7 of concrete tank 4 medium positions.The support bar 9 that wherein paddle is welded on shaft 11 by inclination forms with the ring-like stirring piece 10 of fan that is that is positioned at support bar 9 front ends.
Adopt after the utility model, without tank car displacement and centre, turn materials device, but directly concrete injection is carried out in side discharging, receiving hopper 8 can be accepted the concrete material that concrete tank discharging opening 7 reserves by oblique upper, the discharging opening 7 of described concrete tank is arranged at sidepiece, the oblique receiving hopper 8 of aligned beneath concrete pump on height.
