Description

The utility model relates to tools for laying and repairing rail tracks, in particular, to devices for moving sleepers in the longitudinal direction under the installed rails.

A known design of a device for moving sleepers is described in the patent of the Russian Federation No. 2297484 for the invention "Device for moving sleepers" according to class E01B 29/13, B66D 1/00, declared on 06/29/2005 and published on 04/20/2007.

Said device for moving sleepers contains two drums connected by means of a shaft on which a ratchet wheel is fixed, a carrier with a removable handle, slings made of electrical insulating material connected by a quick-release element installed on one of them, and in this case the drum bodies are connected to each other by jumpers, on one of which has a spring-loaded locking pawl engaged with the ratchet wheel, and around the ratchet wheel the carrier moves with a handle with a built-in power pawl, also engaged with the ratchet wheel, and guides are attached to the drum bodies, covering the sleeper from two sides and equipped with clamps for fixing on the sole of the rail, while the slings are wound on the drums and stretched through the guides with the possibility of connection. The spring-loaded locking pawl and the power pawl are made with the possibility of fixation in the non-working position.

2. In the device for moving the sleepers according to claim 1, according to the utility model, the shaft is made of hexagonal steel with a spanner of 36 mm.

3. In the device for moving the sleepers according to claim 1, according to the utility model, the shaft is made of hexagonal steel with a spanner size of 41 mm.

4. In the device for moving sleepers according to claim 1, according to the utility model, the drum bodies are interconnected by a pipe, pine to a hexagonal shaft.

5. In the device for moving the sleepers according to claim 1, according to the utility model, the drum bodies are provided with protrusions in which grooves are made with a profile corresponding to the profile of the edge of the rail sole.

Making the shaft hexagonal with cantilevered ends protruding beyond the outer ends of the drum bodies for putting on keys with ratchet mechanisms, making each drum consisting of two disks with hexagonal holes coaxially connected by a bushing, and the dimensions of the equally oriented hexagonal holes in the disks correspond to the dimensions of the cross section of the hexagonal shaft, allow to make the device for moving sleepers simpler, more economical and more reliable in operation.

In this case, the shaft can be made of hexagonal rolled products with a turnkey size of 36 mm.

In this case, the shaft can be made of hexagonal rolled products with a turnkey size of 41 mm.

In this case, the housings of the drums can be interconnected by a pipe, pine to a hexagonal shaft.

In this case, the housings of the drums can be provided with protrusions in which grooves are made with a profile corresponding to the profile of the edge of the rail sole.

The proposed set of essential features informs the claimed device for moving sleepers new properties that allow solving the problem.

The claimed device for moving sleepers is novel compared to the prototype, differing from it in that:

1. the shaft is made hexagonal with cantilevered ends protruding beyond the outer ends of the drum bodies for putting on ratchet wrenches, and each drum consists of two disks with hexagonal holes coaxially connected by a bushing, while the dimensions of the equally oriented hexagonal holes in the disks correspond to the dimensions of the cross section of the hexagonal shaft,

2. the shaft is made of hexagonal steel with a spanner size of 36 mm,

3. the shaft is made of hexagonal steel with a spanner size of 41 mm,

4. Drum bodies are interconnected by a pipe, pine hexagonal shaft,

5. The drum bodies are provided with protrusions in which grooves are made with a profile corresponding to the profile of the edge of the rail sole.

The claimed device for moving sleepers can be widely used in tools for laying and repairing rail tracks, in particular, in devices for moving sleepers in the longitudinal direction under the installed rails, therefore it meets the criterion of "industrial applicability".

The inventive device for moving sleepers is illustrated by drawings, which are presented on:

Fig. 1. General view of the device for moving sleepers with a partial section.

Fig. 2. Side view of the device for moving sleepers.

The device for moving the sleepers shown in the drawings (see Fig. 1 and 2) contains two drums connected by a hexagonal shaft 1, each of which consists of two disks 2 coaxially connected by a sleeve 3. The disks 2 have equally oriented hexagonal holes, the dimensions of which correspond to the dimensions of the cross-section of the hexagonal shaft 1. The drums are fixed on the shaft 1 with the help of retaining rings 4. The slings 5 of electrical insulating material are wound on the bushings 3. The ends of the lines 5 are fixed in the slots of the bushings 3 of the drums. At the free end of one of the slings 5 there is a quick-release element (not shown in the drawing) for connecting the free ends of the slings 5.

The shaft 1 is made of hexagonal steel and attached to the housings 6 of the drums with the help of bearings 7. The ends 8 of the shaft 1 cantilever protrude beyond the outer ends of the housings 6 of the drums and are designed to put keys 9 with ratchet mechanisms on them. The size of the cross section of the hexagonal shaft 1 makes it possible to put on its ends 8 keys 9 with dimensions of 36 or 41 mm. Cases 6 of the drums are interconnected by a pipe 10, pine hexagonal shaft 1, and provided with protrusions 11, in which grooves are made with a profile corresponding to the profile of the edge of the rail foot. Guides 12 for slings 5 are attached to the housings 6 with the possibility of covering the sleeper (not shown in the drawings) from both sides.

The device for moving sleepers works as follows.

If it is necessary to remove the sleeper from under the rails, the performer fixes the cases of 6 drums with the help of protrusions 11 with grooves on the sole of the rail 13 so that the guides 12 for the slings 5 cover the sleeper from both sides. The slings 5 are pulled under the rails so that the sleeper (not shown in the drawing) is between them, and connects the ends of the slings 5 at the opposite end of the sleeper with a quick-release element, for example, a carabiner.

After that, the performer puts on the end 8 of the shaft 1 key 9 with a size of 36 mm (or 41 mm with a larger shaft section) with a ratchet mechanism and rocking movements of the key 9 begins to pull the slings 5, winding them around the drum until the sleeper moves to the desired distance. 36 (or 41) mm ratchet wrenches are always included in the railway tool repair kit. The process of installing the sleeper under the rails is carried out in a similar way, while the device for moving the sleepers is fixed on the rail remote from the sleeper.

If it is necessary to increase the effort or reduce the time of movement of the sleeper, two keys 9 with ratchet mechanisms are put on both ends 8 of the shaft 1 at once, this makes it possible to increase labor productivity during the installation or extraction of sleepers.

Thus, the proposed device for moving sleepers is simpler, more economical and more reliable in operation than the closest analogue.

In addition, the use of the proposed device for moving sleepers allows you to increase productivity during the laying and repair of rail tracks.
