Description

The invention relates to railway transport, namely, piggyback cars and can be used for transportation of cargo trailers on public railways, as well as for loading and unloading cargo trailers at prepared terminals.

A piggyback carriage is known from the prior art, comprising a supporting platform and a cantilever part fastened together by a connecting device and equipped with biaxial trolleys; moreover, a horizontal arc arm equipped with extendable vertical supports is mounted on the cantilever part and can be used to move the adjacent end of the supporting platform along it (see Patent EP2419312, CL B61D 3/04, publ. 05.25.2016). The disadvantages of the known device are large dimensions, the need for additional fastening of the arc lever during transportation and the inconvenience of use due to the proximity of the carrier platform to the console part during unloading.

The technical problem is the elimination of these shortcomings and the creation of a reliable and easy to use piggyback car. The technical result consists in increasing the extension of the arc lever while maintaining a compact overall dimensions. The problem is solved, and the technical result is achieved by the fact that in the piggyback car containing the supporting platform and the cantilever part, fastened together by a connecting device and equipped with biaxial carts, on the cantilever part of which is installed a horizontal arc arm equipped with extendable vertical supports, made with the possibility of moving along of the adjacent end of the supporting platform, the arc lever is made of at least three movable sections, each of which is installed on the horizon linen guide and provided with at least one extendable vertical support. The guides of the sections of the arc lever are preferably made in the form of reciprocal grooves and protrusions, and in the folded position, the sections of the arc lever do not go beyond the dimensions of the cantilever part. The connecting device is preferably made in the form of stops installed on the edge of the cantilever part with the possibility of hooking hooks for them made in the upper or lower part of the adjacent edge of the supporting platform.

The end of the movable platform adjacent to the cantilever part is preferably provided with independent retractable vertical supports.

Figure 1 presents the proposed piggyback car in a transport position;

figure 3 - carrier platform piggyback car without a truck;

figure 4 - piggyback car with extended sections of the arc lever;

figure 5 - piggyback car in a turned position;

figure 6 - piggyback car in the unfolded position.

The proposed piggyback car consists of a carrier platform 1 and a cantilever part 2, fastened together by a connecting device. The cantilever part 2 and the end of the platform 1 remote from it are equipped with biaxial railway carts 3. When transporting several piggyback cars at the same time, they are connected using the articulation device 4.

On the console part 2, a horizontal arc lever is installed, consisting of three movable sections: a fixed section 5, a first pull-out section 6 and a second pull-out section 7 (if necessary, more sections can be performed). Each section 5-7 is mounted on the horizontal guide 8 in the form of reciprocal grooves and protrusions and is equipped with at least one extendable vertical support 9. The arc lever is made with the possibility of extension relative to the console part 2 and move along it using the transmission 10 of the adjacent end of the carrier platforms 1 on rollers 11. In the folded position, sections 5-7 do not go beyond the dimensions of the console part, and the supporting platform is fixed by hooks 12.

The connecting device is made in the form of stops 13 mounted on the edge of the cantilever part 2 with the possibility of hooking hooks 14 for them made in the upper part of the adjacent edge of the carrier platform 1. The end of the movable platform 1 adjacent to the cantilever part 2 is provided with independent retractable vertical supports 15.

The loading and unloading of the piggyback wagon takes place in several stages. In the transport (train) position, the retractable sections 6-7 of the arc lever are retracted and do not extend beyond the stationary section 5, i.e. are in the size of the rolling stock. Preparation for bringing the piggyback car to its working position begins by releasing the hooks 14 of the supporting platform 1 from engagement with the stops 13 of the cantilever part 2 and fixing the cantilever part 2 using the retractable supports 9 of the fixed section 5. Then, the arc lever is brought into the working position, for which the sections are extended 6-7 and fix them using the appropriate supports 9. Using the transmission 10 and the energy source, the carrier platform 1 is transferred to the unloading position, while the rotation is carried out by rolling the rollers 11 on the surface not odvizhnoy arm section 5 arc to transfer to the surface of telescopic sections 6-7. After that, the arc lever is unloaded by installing retractable supports 15 of the supporting platform 1, the supports 9 are removed and sections 6-7 are returned to the train position. The carrier platform 1 is transferred to the unloading position by lowering the supports 15. The loading of the piggyback car is carried out in the reverse order.

The described design for moving and rotating the supporting platform of the proposed piggyback car allows increasing the extension of the arc lever while maintaining compact overall dimensions, is reliable in use and allows to improve operational characteristics through the use of mechanical and electromechanical systems.
