Abstract
The utility model discloses a screw conveyor for EPB (earth pressure balance) underground pipe-jacking machines, which is high in volume of excavated earth and convenient to operate. The screw conveyor is composed of a shaftless hollow screw rod (1), a bearing pedestal (2), an earth pressure gauge (3), a conveying pipe (4), a cover plate (5), a motor (6), a driving device (7), an earth excavated outlet (8), and an earth excavated outlet door (9). The screw conveyor is characterized in that the shaftless hollow screw rod (1) is arranged in the conveying pipe (4) at an angle of 30 degrees, and through the adoption of the shaftless hollow screw rod, the size of a discharged obstacle reaches two-thirds of the diameter of a spiral vane. A higher end of the shaftless hollow screw rod (1) is welded on the bearing pedestal (2) and connected with the driving device (7), the earth excavated outlet (8) of the screw conveyor is provided with the earth excavated outlet door (9), a part close to an end not provided with the earth excavated outlet (8) on the conveying pipe (4) is provided with an obstacle discharge outlet, the cover plate (5) is arranged on the obstacle discharge outlet, and the earth pressure gauge (3) is fixed on the cover plate (5).
Description
Technical field
The utility model relates to a kind of development machine and uses conveyer, relates in particular to a kind of earth pressure balance underground pipeline development machine and uses conveying worm.
Background technology
Conveyer is that the material handling of convey materials is mechanical continuously on certain circuit.Conveyer can be divided into ribbon conveyer, conveying worm, noria and roller conveyor by function mode.Conveying worm is made up of conveying worm body, in-out apparatus, drive unit three parts usually; The turnover transport of conveying worm is to be formed by welding helical blade combination on the axis of rotation, and the helical blade of rotation is passed material and carried out the helical feed machine actuating device and accomplish the conveying task.But during implementing, common engineering in the employed conveying worm central axis is arranged; The size that it discharges obstruction can only be 1/3rd of a helical blade diameter; If hinge is advanced bigger obstruction in the conveying worm; Need its in-out apparatus be disassembled and carry out obstruction discharge work,, and lose time and manpower for work brings great inconvenience.In conveyer when work,, the control of casting amount also is a big problem, like running parameter and control unreasonable will working the mischief to equipment and work quality.
Summary of the invention
According to above technical problem; The utility model provides a kind of unearthed amount height, easy to operate earth pressure balance underground pipeline development machine to use conveying worm; By not having axle hollow screw rod (1), bearing support (2), soil pressure table (3), conveyance conduit (4), cover plate (5), motor (6), drive unit (7), soil outlet (8), soil outlet door (9) formation, it is characterized in that a nothing axle hollow screw rod is 30 degree angles and is positioned in the conveyance conduit, do not have the higher end of axle hollow screw rod and be welded on the bearing support; Bearing support is fixed in the cylindrical tracks of the higher end of conveyance conduit; And be connected with drive unit, the conveying worm soil outlet is provided with the soil outlet door, is provided with row's obstruction mouth near the end that soil outlet is not set on the conveyance conduit; Row's obstruction mouth is provided with cover plate, is fixed with the soil pressure table on the cover plate.
The beneficial effect of the utility model is: do not have the employing of axle hollow screw rod, effectively raise the ability of the amount of being unearthed and row's obstruction, discharge the big I of obstruction and bring up to 2/3rds of spiral leaf diameter.When being winched into bigger obstruction in the conveyer, can open cover plate point reverse key and help to take out obstruction, it is time saving and energy saving to dismantle conveyer.Can intuitively read a numerical value on the soil pressure table,, judge whether the duty of screw machine is normal through this numerical value and the pressure in the figure cabin are done comparison.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
According to shown in Figure 1, a nothing axle hollow screw rod (1) is 30 degree angles and is positioned in the conveyance conduit (4), does not have axle hollow screw rod (1) than hanging down an end and gos deep into being used in the clay bin extract earth.Do not have the employing of axle hollow screw rod (1), effectively raise the ability of the amount of being unearthed and row's obstruction, discharge the big I of obstruction and bring up to 1/3rd of spiral leaf diameter.Not having the higher end of axle hollow screw rod (1) is welded on the bearing support (2); Bearing support (2) is fixed in the cylindrical tracks of the higher end of conveyance conduit (4); And be connected with drive unit (7), motor (6) starts the back to drive drive unit (7), and drive unit (7) drives bearing support (2) and does running forward or backwards; Thereby drive not having an axle hollow screw rod (1) does and just changes or reverse; Earth in the clay bin is extracted, and conveying worm soil outlet (8) is provided with soil outlet door (9), goes out to open Tu Koumen (9) during work and can pass through soil outlet (8) discharge smoothly by the earth that extracted.Conveyance conduit (4) is not gone up near setting out an end suitable for reading and is provided with row's obstruction mouth; Row's obstruction mouth is provided with cover plate (5); When being winched into bigger obstruction in the screw machine, can open cover plate (5) some reverse key and help to take out obstruction, it is time saving and energy saving to dismantle conveyer.Be fixed with pressure table (3) on the cover plate (5), the numerical value that shows from last pressure table (3) can be judged the duty of screw machine, if the soil pressure this numerical value and native storehouse in is approaching basically, then genus normally; If this numerical value is lower than the pressure in the native storehouse, explain that then casting is excessive, push-in stroke should be strengthened, otherwise push-in stroke should be reduced.Screw machine carries button just to have changes, reverses, stops third gear, is just transferring to unearthedly, and counter-rotating can help to take out obstruction, is bringing great convenience of work.
Claims (1)
