Construction period, operating personnel's interference is the primary influence factor that causes construction precision to worsen, wherein the interference strength maximum of artificial refining.
Summary of the invention
In view of current double-blocked rail without ballast pouring concrete does not have the Scientific Measurement method, utilize artificial refining to disturb the particular problem that causes the construction precision severe exacerbation, the utility model provides a kind of cast-in-place concrete metering device of using, make concrete through entering mould by pouring position again after metering in advance, reach reduce artificial refining to the interference of construction precision, reduce labor strength, reduce to change and adjust fastener quantity and workload, improve efficiency of construction, reducing the construction costs, the purpose of reserved long-term operation work business maintenance condition.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
The cast-in-place concrete metering device of using of a kind of double-blocked rail without ballast, it is characterized in that, comprise a fixed outer cylinder and an individual metering cylinder that can horizontally rotate around the urceolus axle center be placed in this outer barrel, this urceolus upper end is upper striker plate, lower end is lower striker plate, upper striker plate is provided with charging aperture and is connected with the outlet of storage bin hopper, and lower striker plate is provided with discharging opening, and discharging opening and charging aperture differ 180 °; Be provided with circumferentially uniform a plurality of fan-shaped storehouse lattice with minute storehouse dividing plate in described individual metering cylinder.
In such scheme, the outer wall of described individual metering cylinder and a minute storehouse dividing plate are linked to be integral body, can prevent that minute storehouse dividing plate is deformed by the concrete resistance and affects the accuracy of metering.Described fan-shaped storehouse lattice are 4, and each storehouse lattice cross section is 1/4 circle.90 ° of every intermittent rotaries of individual metering cylinder realize that cloth enters mould 1 time.Described upper striker plate is provided with air vent.Described each lattice bottom, storehouse is respectively arranged with a minute storehouse sliding plate.
CRTS-I type double-blocked rail without ballast is one of primary structure form of high-speed railway slag-free rail, expansion along with national high ferro building size, adopt the engineering of CRTS-I type double-blocked rail without ballast to get more and more, but technical level still rests on the aspect of a large amount of manual work, in the interference short time due to constructor's operation self generation, can't thoroughly eliminate, implement the fluid concrete operation so adopt the utility model metering device, can control preferably that each pouring position is concrete enters modulus, reduce the workman and stand in the interference of refining operation generation in railway roadbed and the time of consumption, for improving the double-blocked rail without ballast construction precision, create favorable conditions, also for more economical applying of CRTS-I type double-blocked rail without ballast, open up more broad space simultaneously.
The accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model apparatus structure schematic diagram.
The horizontal profile schematic diagram that Fig. 2 is individual metering cylinder in Fig. 1.
In Fig. 1-Fig. 2: 1. individual metering cylinder; 2. divide the storehouse dividing plate; 3. turning cylinder; 4. descend axle bed; 5. go up axle bed; 6. power wheel; 7. storage bin hopper; 8. go up striker plate; 9. charging aperture; 10. descend striker plate; 11. discharging opening; 12. air vent; 13, divide the storehouse sliding plate.
The specific embodiment
Referring to Fig. 1, Fig. 2, the cast-in-place concrete metering device of using of a kind of double-blocked rail without ballast, mainly be comprised of storage bin hopper 7, individual metering cylinder 1, charging aperture 9, discharging opening 11, upper and lower striker plate 8,10 etc.First of large diameter steel pipe, make the annular outer wall of individual metering cylinder 1, be welded together to form and there is the rotating individual metering cylinder 1 of certain rigidity with this outer wall and turning cylinder 3 respectively as minute storehouse dividing plate 2 with steel plate, wherein have along circumferential uniform four the 1/4 round storehouse lattice (Fig. 2) of annular outer wall; Each lattice bottom, storehouse arranges respectively one minute storehouse sliding plate 13.Make and be with bevelled storage bin hopper 7 with steel plate, with steel plate, make respectively on circle, lower striker plate 8, 10, offer charging aperture 9 and air vent 12 on upper striker plate 8, offer discharging opening 11 on lower striker plate 10, upper striker plate 8 and lower striker plate 10 are welded on respectively to slightly larger in diameter (discharging opening and charging aperture differ 180 °) on another large diameter steel pipe of individual metering cylinder 1 annular outer wall, upper, lower striker plate 8, 10 centre-drilling holes pass turning cylinder 3, turning cylinder 3 is passed through to upper and lower axle bed 5, 4 are fixed on lower striker plate 10 and storage bin hopper 7, in turning cylinder 3 bottoms, power wheel 6 is installed.
The know-why of this metering device is:
1. utilize individual metering cylinder 1 accurate measurement concrete demand, and utilize the outer wall of individual metering cylinder and a minute storehouse dividing plate to form integral body, prevent that minute storehouse dividing plate from deforming and affecting metering accuracy under the concrete drag effect;
2. utilizing power wheel 6 to drive the horizontal batch (-type) of individual metering cylinder rotates;
3. utilize fixedly charging aperture 9 on upper striker plate 8 to feed supplement in the individual metering cylinder;
4. the fixedly discharging opening 11 under utilizing on striker plate 10 is to the pouring position cloth;
5. utilize the concrete storage level in storage bin hopper 7, meet the continuity of pouring practice;
6. utilize air vent 12 that individual metering cylinder inner concrete surface and atmosphere are connected, overcome the impact of negative pressure on blanking.
During fluid concrete, add concrete in storage bin hopper, starting motor rotates individual metering cylinder 1 low speed batch (-type), concrete in storage bin hopper is filled one of them storehouse lattice of individual metering cylinder under the effect of gravity, realize metering to fill concrete in the measuring chute lattice, when the individual metering cylinder rotates, continue to the lattice material filling of next storehouse, the batch (-type) by the individual metering cylinder rotates to be realized to material filling successively in different storehouse lattice; Be subject to stopping that the concrete of metering in minute storehouse is unlikely and being thrown out of of striker plate in rotation process; Under the backwater effect of lower striker plate, the unlikely downward leakage of concrete in the lattice of storehouse; When the storehouse lattice turn to the discharging opening position, leak into mould under concrete is automatic under Action of Gravity Field, in storehouse lattice bottom, sliding plate can impel concrete to enter smoothly mould, eliminate the accuracy of dead angle, bottom residual concrete impact metering, the air filled into by air vent, the blanking resistance formed for overcoming the too fast suction function of concrete discharging; Under rotary action, the hole capital after selling all securities lattice after discharge are got back to successively the storage bin hopper below and are again connected material.This metering device can coordinate the step-by-step movement casting equipment and, by the program control batch (-type) metering cloth of realizing, also can measure cloth for controlling for realization on simple and easy apparatus for pouring by the people.
Because the utility model purpose is the metering of double-blocked rail without ballast pouring concrete, so adopted the design of hopper fixed volume, when changing occasion, can change hopper and corresponding corollary apparatus the design of into more piece combined type when metered volume, facilitate the adjustment of metered capacity.
