Description
Technical field
The invention belongs to construction equipment technical fields, are related to a kind of multiple coil concrete conveying system.
Background technique
Screw machine is widely used in every profession and trade, such as building materials, chemical industry, electric power, metallurgy, coal, grain industry, is suitable for water
Put down or tilt conveying powdered, powdery and small block material, such as coal, ash, slag, cement, grain.
In building trade, screw machine is widely used in the feeding of concrete, feeding height is able to ascend, for existing market
On tilt-lift conveying screw machine for, there are the following problems：
1, due to single shaft, bearing shell is set outside shaft, there are gap between bearing shell and conveyance conduit, delivery head compared with
It in the case where height, is influenced by concrete bearing, delivery head is higher, gap of the concrete between bearing shell and conveyance conduit
The material of interior leakage is more, that is, forms feed back, and transfer efficiency is caused to reduce, and due to single shaft, load is also very big, unfavorable
In shaft traveling comfort；
2, in general, existing screw machine cooperates speed reducer using driving motor, shaft is then reconnected, because of shaft
Rotation speed need lower, to adapt to the transport of the relatively large concrete of viscosity, the setting of speed reducer not only makes driving electricity
The kinetic energy efficiency of machine is lower, moreover, because deceleration is bigger, body is caused to shake, and noise is larger, is unfavorable for screw machine
Overall performance；
3, due to the presence in gap between bearing shell and conveyance conduit, in the end of conveyance conduit, conveyance conduit
The storage of concrete is fewer, existing screw machine, and using single shaft, revolving speed is remained the same from beginning to end, and is that there are great Rong in conveyance conduit
The conveying continuity in long-pending gap, concrete is poor, and negative pressure can not be formed in conveyance conduit, causes concrete feed back,
Transfer efficiency substantially reduces, and even, when delivery head reaches a certain level, concrete can not be delivered to specified altitude assignment completely；
4, there is also precipitatings and layering during transportation for concrete, since screw machine is to make coagulation by the rotation of bearing shell
What soil was promoted, and revolving speed is relatively slow, actually during transportation to the stirring of concrete be almost without, if conveying
Height is higher, and only concrete comprehensive performance changes, and is unable to satisfy the watering requirement of concrete；
5, the tilt angle of conveyance conduit can not be adjusted, and the change of pouring position is realized in the position for needing to control ground installation
Change.
Summary of the invention
In view of the above problems existing in the prior art, the purpose of the present invention is to provide a kind of multiple coil concrete conveyings
System, the technical problem to be solved by the present invention is to how realize the stirring of concrete during transportation, to maintain concrete
Performance it is constant.
Object of the invention can be realized by the following technical scheme：A kind of multiple coil concrete conveying system, it is special
Sign is, this concrete conveying system includes ground storage tank, driving motor, conveyance conduit and at least two shafts, described turn
Axis is plugged in conveyance conduit, is connected between adjacent shafts by a planetary reduction gear, lower end and drive positioned at the shaft of bottom
It is connected between the output shaft of dynamic motor by a universal joint, passes through axis at the top of the upper end of the shaft on top and conveyance conduit
It holds connected；

The working principle of this system is as follows：
Ingredient is completed and the concrete stirred evenly is contained in the storage tank of ground, relatively high by the shaft of lower end
Revolving speed, efficiently concrete is extracted, is made it into conveyance conduit, since the planetary reduction gear in this system is anti-
To retarder, make the rotation speed of adjacent shafts on the contrary, oppositely arranged to the bearing shell in adjacent shafts, conveying direction is made to keep one
It causes, that is, is delivered up, by the deceleration of planetary reduction gear, keeps the revolving speed of the shaft closer to upper end slower, to eliminate bearing shell
The regurgitant volume of concrete is caused in gap between conveying pipeline inner wall, it is ensured that is formed in conveyance conduit without obvious cavity, to make
Conveying negative pressure is kept in conveyance conduit, improves transfer efficiency.
It is not difficult to find out that in this system, due to the setting of planetary reduction gear, make the direction of rotation of adjacent shafts on the contrary, to
Biggish shearing force is formed in the junction of adjacent shafts, the concrete high-efficiency at the position is mixed, prevents concrete from conveying
It precipitates and is layered in the process.
In this system, in such a way that connecting plate is set on the shell of planetary reduction gear, each shaft is made individually to enjoy two
The support force of end bearing support, so that it is guaranteed that the stationarity of the stationarity of shaft rotation and entire transmission process, it is thus possible to subtract
Gap between small bearing shell and conveyance conduit, improve transfer efficiency, be not concerned about bearing shell due to the concentricity of shaft is lower with conveying
It is worn between the inner wall of pipeline.
In this system, cancel conventional helical machine shaft bottom setting retarder structure, and use shafts at different levels it
Between the mode of retarder is respectively set, increase feed pressure, certainly, driving motor is also required to using decelerating motor, still, phase
Than for, it is not necessary that shaft is reduced to too low, so that the shaft of bottom end be made to can result in feed pressure increase, reduce concrete reflux
Amount.
In this system, connecting plate is Openworks shape, and concrete has carried out effective dispersion when passing through connecting plate, by squeezing
Mode out stirs concrete, since this system is by the way of multiple coil, concrete during transportation,
Having a rest property is stirred, so that concrete effectively be avoided to precipitate and be layered.
The efficient conveying of longer distance, more high inclination-angle may be implemented by the way of multiple coil in this system, steady
Property, transfer efficiency and latter end discharging concrete quality it is fabulous.
Corresponding reduction ratio can be set according to factors such as concrete viscosity, concrete performance, delivery head, conveying inclination angles
Planetary reduction gear or each planetary reduction gear different reduction ratio is respectively set, make feed pressure, conveying stationarity and conveying effect
Rate is more excellent.
Using planetary reduction gear, transmission stability is preferable, and the concentricity between each shaft is preferable.
In a kind of above-mentioned multiple coil concrete conveying system, opened up on the ground storage tank it is jagged, it is described
Conveyance conduit is plugged in notch, has gap between the conveyance conduit and the inner wall of notch, in the shaft of lower end
Bearing shell is partially disposed in the discharge tank of ground.
In a kind of above-mentioned multiple coil concrete conveying system, this conveying system further includes a supporting cylinder, institute
The cylinder body lower end for stating supporting cylinder is fixedly installed a pedestal, and several connections are provided on the outer tube wall of the conveyance conduit
The top of block, the push rod of the supporting cylinder can be detachably hinged with link block.
