SU64224A1 - A device for collecting old ballast, mounted on a track-lifting, for example, ballasting machine - Google Patents

Description

The invention relates to track-lifting, for example ballasting, traveling machines, equipped with a device for removing contaminated ballast from under the rail whip overhaul - and reconstruction) of the track. Such devices, equipped with a transverse outfeed Tfansortyor belt and a knife undercutting ballast, can also be used in machines for cleaning arrows from snow, in machines for softening slopes, etc.

In the proposed device, in order to protect the transport from the impact of the ballast, the cutting knife is hollow to accommodate the driving and driving branches of the conveyor. Guide rollers are installed at the ends of the latter, which ensure the convergence of the branches of the conveyor to reduce the thickness of the cutting knife.

In the schematic drawing of FIG. I depicts a cross-section of a device mounted on a ballasting machine; FIG. 2 is a top view and FIG. 3 shows a section along A - A in FIG. one.

To the frame 7 of the overhead, for example, ballasting machine carrying the frame 8 with the depth mechanism 9, is attached with the help of folding brackets 6 a device for removing the old ballast, comprising a cutting hollow knife 5 and an external conveyor belt I with a drive station 2. the knife 5 is located the conveyor I, the leading wheels and the wheels of which are brought closer to each other by means of the guide rollers 4, in order to maximally reduce the dimensions in height (reduce the thickness of the knife 5). Between the branches of the conveyor 1 there is a metal sheet 12 of the knife 5, which serves to support the leading branch a and to prevent it from contacting the driven branch b of the transporter. Under the lower (slave) (branch b is located the sheet 19 of the knife 5, which protects the conveyor branch from friction with the ballast.

Located on the side of the roadside, the drive station 2 of the conveyor consists of a drive drum 13, an electric motor 14 and a pulley with a drive belt 15 ,.

The electromotor 14 is mounted on a horizontal platform 16. Between this platform and the leading branch of the conveyor there is a passage for material carried by the JDOM transport. Conduct drum 13 with 1 shaft of a sub-dipyika; and. fixed in the side of the outer sheets 10.,

. On the side / in between (the other side of the knife 5) there is a guide drum 3, covered with a casing 17, which protects the drum 3 and the guide roller 4 from falling into the sand. The casing 17 is made in the form of a shuttle to reduce resistance when moving a chevron, in ballast,. On top in the middle part of the knife there is a sheet 11 with a special section, intended for the equal loading of ballast of the conveyor 2 along the entire width of the latter.

The front inclined sheet 18 but; ZA 5 is designed to lift -: ballast and facilitate the work of the mouth device.

During operation, the ballasting machine, equipped with the proposed cessation device, stops at the place of commencement of work and raises the rail whip to its maximum height with its lifting device. After that, with the help of devices under the lash, the cesspool device is installed without any prior raking of the ballast 1 manually. - Then the ballast roving machine is set in motion. As the machine progresses, the dwelling device is gradually buried and, thus, the lash is gradually lowered. When the cutting knife is lowered to the desired depth, the machine keeps moving evenly

with the minimum speed forward. The ballast along the front inclined sheet 18 rises under the pressure on the upper patch sheet Neither is poured onto the upper branch of the endless belt of the conveyor. Leny,:; pp is driven in the drike electric motor, ballast: a., on the sidelines. Since the mechanism is double-bodied, it is possible to work in both directions without its installation. When moving in the opposite direction, you only need to shift the top invoice sheet 18.

Subject invention

,; one; EFFICIENCY for the old ballast, installed on a track-lifting, for example, ballasting machine, using a cross-sectional out-of-band conveyor belt and a knife that cuts the old base part, that the cutting knife is made hollow for the OPPORTUNITY of placing inside it the driven and leading branches of the belt conveyor, in order to protect the latter from the effects of ballast.

2. The form is executed on the device pop. 1, characterized in that, in order to reduce the thickness of the knife, rollers are installed at both ends of the conveyor to bring the leading conveyor to the follower branches closer together.

3. The form of the device according to claim 1, characterized in that the guide drum and the conveyor roller are protected from the impact of the ballast by a casing which, in order to reduce the resistance when moving in the ballast, the shape of the shuttle is communicated.
