Description

Portable cast-in-place device for ballastless track concreting

Technical field

The utility model relates to concrete casting device, is specially the removable cast-in-place device for the ballastless track concrete construction.

Background technology

In the double-blocked rail without ballast work progress, the construction logistics is a great problem of construction organization, because job site is narrow, with concrete transport vehicle, can't make concrete directly into mould, take special-purpose concrete casting machine to be built operation abroad, by the imperial formula feeding device of volume, concrete is sent in casting machine, but casting machine apparatus expensive, processing and manufacturing cycle are long, technical sophistication, fault rate is high, the domestic simple and easy method that often adopts substitutes, in the hope of reducing construction cost.

At present, double-blocked rail without ballast concreting operation often adopts the mode of pumping to complete concrete to enter mould, but because pumping technology has specific (special) requirements to concrete slump, causing the mixing concrete water supply volume larger, is one of important origin cause of formation of railway roadbed board concrete cracking; Simultaneously, a large amount of constructors need stand in auxiliary concrete on the section of track and enter the operations such as mould, and construction precision is had a negative impact, and the rear track circuit ride comfort that causes laying a railway track is adjusted workload and strengthened, and construction cost significantly improves;

The double-blocked rail without ballast concrete casting building technology of domestic-developed, be to take pumping of concrete as basis, fails to consider railway roadbed plank split and the large key element of construction precision two, haves much room for improvement and improve.For effectively controlling the railway roadbed plank split and improving the ballastless track construction precision, or take concrete directly into the mould mode as good, but the discharge chute limited length of general concrete waggon can't realize that concrete is directly into mould.

Summary of the invention

In view of drawback and the concrete transport vehicle of pumping of concrete can't be directly into the problems of mould, the utility model provide a kind of can be by concrete transport vehicle discharge chute spreading, and can move with concrete transport vehicle, realize that concrete is directly into mould, reach " the cast-in-place device of mobile concrete " simplifying construction, reduce the construction cost purpose.

For reaching above purpose, the utility model takes following technical scheme to be achieved:

Portable cast-in-place device for a kind of ballastless track concreting, comprise the vehicle frame that can vertically move, and is provided with chute on vehicle frame, it is characterized in that, described chute is connected with vehicle frame by transfer, is provided with the device that hoists in transfer, and an end of chute connects the telescopic groove that connects material; The other end connects rotary distributing trough, and chute is realized the adjustment of the chute gradient by the device that hoists.

In such scheme, described transfer comprises the rotating shaft that is located at the vehicle frame middle part, and this rotating shaft connects a horizontal rotating disc, and horizontal rotating disc turns to and is connected with the chute horizontal direction by gradient regulating shaft and the device that hoists.

The end that described chute is connected with rotary distributing trough is provided with the cloth control plate.The described device that hoists adopts the rhombic lifting jack principle to make.One end of described chute connects the telescopic groove that connects material and adopts the mode of wheel and rack to adjust the relative position between chute and telescoping connection hopper.

The logistics tissue is one of difficult point of double-blocked rail without ballast construction, and while being forced to adopt pumping technology, concrete water-cement ratio is bigger than normal in the past, is unfavorable for Concrete Crack Control; Employing is during directly into the mould casting craft, and the discharging chute limited length of concrete tank, can't realize that concrete is directly into mould, needs a large amount of indirect labors.After adopting the utility model device, can facilitate chute and concrete tank contraposition, can make again concrete directly into mould, solved the difficult problem of the concrete pouring construction (especially the second line) of double-blocked rail without ballast, be improved to directly into mold technique support is provided for domestic pumping of concrete enters mold technique, popularizing application prospect is wide.

The specific embodiment

Referring to Fig. 1 Fig. 2, portable cast-in-place device for a kind of ballastless track concreting, comprise the vehicle frame 1 with four wheels 2, vehicle frame 1 one ends are drawing handle 3, the vehicle frame middle part is provided with rotating shaft 5 and connects a horizontal rotating disc 4, and horizontal rotating disc can turn to and be connected with the chute 8 of an arc by gradient regulating shaft 6 and gradient lifting device 7, and arc chute 8 one ends connect a telescopic groove 9 that connects material, the other end connects rotary distributing trough 10, and is provided with a cloth control plate 8-1.

The operating principle of this device

The cast-in-place device of movable type is pushed to the concreting position along between the double-blocked rail without ballast line; By chute 8 half-twists and fix with pin; Adjust the chute gradient, with the moistening chute of clear water; Adjust telescopic groove 9 length that connect material, make the concrete tank discharging opening over against the groove that connects material; Concrete, under the effect of self mobility, prolongs the smooth groove of the gradient and flows to rotary distributing trough 10, adjusts as required the cloth position; When certain position cloth finishes, with the cloth control plate, 8-1 suspends cloth, mentions plate behind the change position and continues cloth; After a certain paragraph cloth finishes, but advancing device carries out the operation of next paragraph; After the concreting end of job, by chute 8 half-twists, with pin, fix, shift out operating area, with clear water, thoroughly clean up standby.
