Description
[technical field]
The present invention relates to a kind of mixed earth conveying device, be specifically related to a kind of long distance gentle incline appts. for transferring ready-mixed concrete.
[background technology]
At present, concrete conveying has at the scene been a very common construction technology, according to mode of movement classification, can be divided into: concrete vertical transport, horizontal feed, inclined-plane are carried.Wherein, have at the mode of movement on inclined-plane: belt conveyer transport, the transport of concrete pump machine, tumbling barrel transport, elephant trunk or vibrating spout etc.The concrete conveyance mode of present routine is chute, tumbling barrel conveying, but minimum angles is successful story on 30 ° of inclined-planes only, when bevel angle is less than 30 °, inclined-plane carries out conventional chute, tumbling barrel conveying just can not be successful, as adopted the construction method of concrete pump machine conveying, is then difficult to arrange pump flat tube section redundantly, as easy as rolling off a log generation concrete plugging in conveying, and long construction period, pump machine lease expenses is high, considerably increases construction cost.
[summary of the invention]
The object of the invention is to for above technical deficiency, provide a kind of long distance gentle incline appts. for transferring ready-mixed concrete, structure of the present invention is simple, conveying successful.
Technical scheme of the present invention is as described below: a kind of length distance gentle incline appts. for transferring ready-mixed concrete, comprises the removable triangular platform of the adjustment blanking height stopping loading concrete tank, prevents concrete disintegration also just to the aggregate bin of feed opening, the feeding pipe connected into by elephant trunk and chute engaged with described aggregate bin lower end and the steel pipe support supporting described feeding pipe.
According to above-mentioned technical scheme, described chute terminal discharge mouth place is provided with the vertical erosion control baffle plate preventing discharging from splashing.
According to above-mentioned technical scheme, described erosion control baffle plate is arranged on apart from described chute end 0.5 meter of, and splicing is highly 1 meter.
According to above-mentioned technical scheme, between described elephant trunk and described chute, adopt flange connection between described chute and chute, one end of described elephant trunk is connected with the lower end of described aggregate bin, and the other end is connected with described chute.
According to above-mentioned technical scheme, the square terrace with edge that described aggregate bin 4mm steel plate is made into, greatly suitable for reading, lower young, sectional dimension suitable for reading is 1.0m × 1.0m, and bottom size is 0.3m × 0.3m.
According to above-mentioned technical scheme, described removable triangular platform is the triangular form platform be welded into steel plate and channel-section steel.
Beneficial effect of the present invention is: the successful experience drawing concrete chute transport, sliding chute transportation, the mode adopting elephant trunk and chute to combine carries out inclined shaft conveying, and technique is simple, easy to operate, easy to maintenance, material can reclaim, safety and can ensure construction quality.

[detailed description of the invention]
The present invention is applicable to the long solution apart from the tunnel under 28.26 ° ~ 30 ° gentle incline conditions, inclined shaft, hillside concrete conveyance problem of 84m ~ 100m.
As Figure 1-4, a kind of long distance gentle incline appts. for transferring ready-mixed concrete, comprise the removable triangular platform 4 of stopping the adjustment blanking height loading concrete tank 1, prevent concrete 13 from emanating also just to the aggregate bin 3 of feed opening 2, the feeding pipe connected into by elephant trunk 6 and chute 7 engaged with described aggregate bin 3 lower end and the steel pipe support 10 supporting described feeding pipe, described chute 7 terminal discharge mouth 11 place is provided with the vertical erosion control baffle plate 12 preventing discharging from splashing, described erosion control baffle plate 12 is arranged on apart from described chute 7 end 0.5 meter of, splicing is highly 1 meter, between described elephant trunk 6 and described chute 7, flange 9 connected mode is adopted between described chute 7 and chute 7, one end of described elephant trunk 6 is connected with the lower end of described aggregate bin 3, the other end is connected with described chute 7, the square terrace with edge that described aggregate bin 3 is made into 4mm steel plate, greatly suitable for reading, lower young, sectional dimension suitable for reading is 1.0m × 1.0m, bottom size is 0.3m × 0.3m, described removable triangular platform 4 is the triangular form platform be welded into steel plate and channel-section steel.
As shown in Figure 1, at inclined shaft hole, " removable triangular platform 4 " is installed, to control platform of blanking setting height(from bottom)." removable triangular platform 4 " is the platform being welded into right angle trigonometry type with steel plate and channel-section steel, and two panels, is arranged on inclined shaft hole place altogether.After concrete tank 1 arrives building site, in reversing " removable triangular platform 4 ", in-site measurement controls feed opening height, and adjustment concrete 13, from the falling bodies height 1.9 meters of tank car feed opening 2 discharging, is located with location drift 5.
Aggregate bin is made into square terrace with edge, and concrete 13 is collected in effect, prevents material to be scattered.With the field fabrication of t=4mm thin iron steel plate, installation, sectional dimension suitable for reading is control 1.0m × 1.0m square, and bottom size is 0.3m × 0.3m square, height 1.0m.Gather materials end opening and elephant trunk interface, and use mortar, flax silk carry out joint filling, mortar leakage prevention.
As shown in Figure 2 and Figure 3, for convenience of installing and removing, elephant trunk 6 and chute 7, chute 7 and the connection of chute 7, adopt flange 9 connected mode.Flanged plate is 5mm semicircular arc steel plate, is welded on the termination of chute 7 sections.The planeness of flanged plate is most important to installation quality, therefore after flanged plate welding, because carrying out roughness measurement, can adopt small sand turbine grinding process as flatness error exceeds standard.
Installing screw hole 14 specification is
, installing screw specification is M12 × 16mm.After chute 7 is in place, carry out shaft centerline measurement with instrument, control axis deviation, connects by connecting screw.Screw is installed by just twisting, Zhong Ning branch carries out; For preventing joint spillage, flange 9 junction, adds film pad, and during flange 9 is installed, control the interface mismatch of chute 7 sections termination, mismatch error is not more than 0.5mm.
As shown in Figure 4, concrete 13 material is greater than zero at the discharging speed of outlet, can go out situation.For preventing in the impact of discharging opening 11 place concrete 13, install vertical erosion control baffle plate 12 at discharging opening 11 place, vertical erosion control baffle plate 12 uses camber line steel plate, and length 1.0 meters is perpendicular to the ground, is welded on strutting system.
Shown in apparatus of the present invention and accompanying drawing, be only a part for the better embodiment of the present invention, this method can not be limited to this.Under the condition not departing from apparatus of the present invention, any variation that those skilled in the art do, all belongs within protection of the present invention.
