Description

TECHNICAL FIELD

The invention relates to the field of railway transport, in particular to the loading of a car semi-trailer on a 1520 mm railway gauge platform wagon on which it is transported, to the loading of the semi-trailer using the loading equipment and the fastening after loading onto the platform wagon.

STATE OF THE ART

The known prior art is patent RU2675745 (C1) dated 12/24/2018.

A method of loading a car semi-trailer into a specialized railway car, in which the semi-trailer is placed by a tractor in a removable basket, mounted on support legs resting on an additional cross beam of the basket, where the wheels of the semi-trailer are located between the cross beams of the basket. Using cargo lifting equipment, the bag with the semi-trailer is lifted and placed in a specialized wagon. Here it captures.

The disadvantage of this invention is that such a solution requires a specialized rail car, basket and special lifting equipment.

The closest analogue to this invention is EP1582496 patent 2005-10-05. The method of moving a semi-trailer and the means of implementing this method, when lifting the semi-trailer from the ramp, loading, fixing and transporting it, including the crane for lifting the semi-trailer from the ramp with slings, fastening means for reloading the semi-trailer with a lifting cross beam and at least two wheel gripping elements. This patent patents various options for fixing a beam with a semi-trailer on a specialized rail car platform.

The disadvantage of this invention is that the semi-trailer is loaded and fixed on a pocket (recessed) wagon specially made for transporting truck semi-trailers.

In Europe, it is customary to transport large semi-trailers on railway networks in special railway freight wagons, called pocket (recessed) wagons. These wagons are adapted to the 1435 mm wide railway track. However, railway tracks of other standards are more common in Lithuania, Latvia, Estonia, Ireland, Finland, Portugal and Spain. In Lithuania, the largest railway network consists of 1520 mm gauge. There are few specialized railcars for this gauge, adapted to carry semi-trailers.

This specially developed semi-trailer loading, fixing and transport system allows semi-trailers to be reloaded and fixed on a 1520 mm railway gauge platform car.

ESSENCE OF THE INVENTION

The semi-trailer loading and fastening system, designed to achieve the specified technical effect, from a special ramp on a 1520 mm gauge railway platform car and its method of use, when the semi-trailer reloading equipment includes separate lifting crossbars and slings, which can be moved from the special ramp using all of the set, standard Semi-trailers with 3 axles (no more than 2 wheels on an axle, wheel sizes from 265/55 R19.5 to 385/65 R22.5), 4 meters high. Specifically, the lower semi-trailer lifting cross member, to lock the semi-trailer fifth wheel with an automatic locking mechanism that locks the fifth wheel and prevents the lifting cross member from coming off, and the lower lifting cross members, to grip the semi-trailer wheels. Moved semi-trailers on a 1520 mm gauge railway platform car, for fixing the latches (removably fixed on the railway platform car) for the lower semi-trailer lifting crossbars, for grabbing the rear wheels of the semi-trailer, and for inserting and locking the lower semi-trailer lifting crossbar with the fixed toe of the semi-trailer, there is a support frame with a socket-removable , this support frame is fixed removable on the platform of the railway car, and therefore modernization is not required by changing the technical characteristics of the car.

DETAILED DESCRIPTION OF THE INVENTION

The loading and fixing system of the semi-trailer 21 on the railway platform car 22 (Fig. 7) includes separate lifting crossbars 1, 2, 3 (Fig. 1, Fig. 2, Fig. 4 and Fig. 5) and slings 20, which are used for all in the set, from the special ramp 4 (Fig. 3) for the tractor with a semi-trailer to drive up (in the corresponding places of the ramp 4 there are provided outlets - sockets 6, 7 for the lower lifting crossbars 2 and 3), standard semi-trailers 21 are moved onto the 1520 mm gauge railway platform wagon 22, on which has removably attached means for fixing crossbars 2 and 3.

The method of using the loading and fixing system of the semi-trailer 21, when the tractor with the semi-trailer 21 drives onto a special ramp 4 (Fig. 3) to a position where all the wheels of the rear axles fall into their designated places, on the lower lifting crossbars 2, to grab the wheels of the semi-trailer, ( Fig. 4) in the slots 7 of the ramp 4. The tractor leaves the semi-trailer 21 on the ramp 4, then the crane raises the upper lifting beam (Fig. 1, Fig. 2) with the slings 20, and fastens the slings 20 on the corresponding beams 2 and 3 (located in slots 6 and 7 of the ramp), and the lower lifting cross member 3 of the semi-trailer is raised so that the toe of the semi-trailer's saddle is adjusted to the saddle toe slot 11 of the lower lifting cross member 3. An automatic locking mechanism is designed for the lower lifting cross member 3 in slot 11, which fixes the saddle finger and prevents the lower lifting crossbar from unhooking 3. The lock can be opened manually from either side of the crossbar. The lock can be in the unlocked position only as long as the semi-trailer presses against the surface of the lower lifting crossbar 3 (fingers 12 of the latches are pressed (Fig. 5)). When the semi-trailer moves away from the lower lifting bar, lock 3 automatically locks and is ready for the next coupling with the fifth wheel of the semi-trailer. The lock handle 13 is provided with a marking 14 (elongate hole) that visually informs when the lock is in the unlocked position. To unlock and lock the lock in the unlocked position, the handle 13 is pulled from either side and pushed to the side, if the fingers of the latch 12 are pressed, the lock will remain in the open position.

After moving the semi-trailer 21, the slings 20 are unhooked from the lifting crossbars 2 and 3, the semi-trailer 21 is fixed on the railway platform wagon 22 with a gauge of 1520 mm, (Fig. 7) with fasteners (removably fixed on the railway platform wagon 22) (Fig. 4) for the lower parts of the semi-trailer lifting for the crossbars 2, to grab the rear wheels of the semi-trailer, and (Fig. 5) the lower semi-trailer lifting crossbar 3 with the semi-trailer fifth wheel locked in the socket 11, is placed in the socket-outlet 16 of the support frame 5 (Fig. 6). The crossbar 3 is fixed on the support frame 5 from on both sides, with fasteners 17, when the support frame 5 is fixed on the railway platform wagon 22 in a removable manner, and therefore modernization of the railway platform wagon (22) by changing the technical characteristics of the wagon is not required.

The unloading process is carried out in reverse order.

The proposed car semi-trailer 21 loading system and the way it is used is not limited to the above example, it can be applied in other semi-trailer loading cases as well.
