Description

Technology area

The claimed utility model relates to handling equipment used to move a basket with a car semitrailer.

Prior art

One of the methods of cargo delivery is piggyback transportation - combined rail-road transportation of road semi-trailers, in which a road semi-trailer travels part of the way on a railway platform car. To place a semitrailer on a flat car, special devices can be used - baskets, which also serve to move the semitrailer to or from the car.

From the RF patent for invention No. 2675745, IPC B61D 47/00 B66F 7/02 publ. 12/24/2018, [1], a lifting device is known, with the help of which the basket is removed from the platform car using the brackets on the side beams and placed on the ground surface.

Also known is a lifting device (European patent EP 2902299 A1, IPC B61D3 / 18; B61D47 / 00; B61J1 / 10; B65G63 / 00; B66C1 / 28; B66F7 / 24, publ. 08/05/2015, [2]) containing lifting harnesses with grips.

In addition, for lifting baskets with semi-trailers, specialized loaders are used - reachstackers, equipped with special equipment - the lower grip "piggy back" (Yuri Petrov, article "Reachstackers - container handling loaders" in the magazine "Sklad i Tekhnika", No. 1-2006. The journal is registered with the Press Committee of the Russian Federation, certificate PI No. 77-16221, publication on the Internet https://sitmag.ru/article/9988-richstakery-pogruzchiki-dlya-obrabotki-konteynerov, hereinafter - [3] ).

The use of the lower piggy back grippers for lifting baskets with a semitrailer has the following disadvantage. The piggy back grips are secured to the basket lugs using a significant lateral pressure force. Thus, the structure of the basket must also be designed for the specified clamping force, which, taking into account other loads acting on it (the gravity of a loaded semitrailer, longitudinal loads when transporting the basket in a carriage), leads to an increase in the container mass of the basket, and, accordingly, entails the increase in the cost of rail transportation of the basket with a semitrailer due to the increased tariff rate.

Traverses with flexible slings are devoid of this drawback. In such traverses, the fixation of the grippers (for example, hooks) to the lugs of the basket is carried out due to the mutual engagement of the grippers and lugs when the slings are tensioned.

Known selected as a prototype traverse for moving a basket with a car semitrailer, containing longitudinal beams, cross beams, nests are placed on the beams for placing hook hangers in them, the longitudinal and cross beams form a rectangular frame, in the corners of which corner fittings of large-tonnage containers are installed (RF patent for utility model 193221, IPC B66C 1/68, publ. 10/17/2019, [4]).

This crosshead is compatible with a reachstacker [3].

The longitudinal and transverse distance between the corner fittings on the traverse to ensure compatibility with the reachstacker is regulated by regulatory documents, for example, GOST R 53350-2009 [5].

To eliminate the risk of damage to the semitrailer body by hook suspensions during loading and unloading operations using a traverse, it is necessary to ensure sufficient clearance between the semitrailer body and these suspensions. Accordingly, the lateral distance between the hook suspensions must be greater than the width of the semi-trailer body, which in turn is greater than the lateral distance between the corner fittings of the traverse.

Thus, in the specified prototype, due to the placement of corner fitting stops in the corners of the traverse, the width of the traverse is insufficient to accommodate the attachment points of the hook hangers with the possibility of providing the necessary clearance between the hook hanger and the body of the semitrailer.

This problem can be solved by placing the attachment points of hook suspensions on outboard brackets, however, in this case, the strength of the traverse frame decreases due to the occurrence of significant bending moments associated with the appearance of a shoulder from a vertical force when lifting a basket with a semitrailer.

Disclosure of the essence of the technical solution.

A technical problem, the solution of which is provided in the implementation or use of the utility model, is the need to ensure the safe carrying out of loading and unloading operations using a traverse.

The technical problem to be solved by the utility model is to increase the safety of the semitrailer during loading and unloading operations using a traverse.

The technical result provided by the utility model is to ensure safe loading and unloading operations using a traverse.

The specified technical result is achieved due to the fact that the traverse for moving the basket with a car semitrailer contains longitudinal and transverse beams, the longitudinal and transverse beams form a frame on which corner fittings are installed, characterized in that brackets are installed on the frame, on which flexible loop slings are suspended ...

When using flexible looped slings for hooking the basket with a semitrailer, there is no risk of damage to the semitrailer body when lowering the traverse with hook slings, as in the prototype, during loading and unloading operations.

Thus, in comparison with the prototype, it provides safe handling and no risk of damage to the semi-trailer body.

Thus, the claimed utility model differs from the prototype in that brackets are installed on the frame, on which flexible loop slings are suspended.

The proposed utility model is illustrated by graphic material, where the figure shows a general view of a traverse for moving a basket with a car semitrailer, containing longitudinal beams 1, cross beams 2, corner fittings 5, characterized in that brackets 3 are placed on the frame, on which flexible looped feet are suspended 4.

Implementation of the technical solution.

The traverse for moving the basket with a car semitrailer (see figure) contains longitudinal beams 1, cross beams 2. Longitudinal and cross beams 1 and 2 form a frame on which corner fittings 5 are installed, while brackets 3 are placed on the frame, on which flexible looped feet 4.

The fittings 5 are preferably made in the form of standard corner fittings of large-capacity containers, but can be made in the form of fittings of a different design, allowing the spreader mechanism of the reachstacker to be fixed to the traverse.

Placing fittings on the frame means that the fittings 5 can be fixed to the surface of the frame beams, or they can be fully or partially inside these beams.

In this case, the location of the beam across the traverse does not limit the implementation of the beam only to a straight beam located perpendicular to the longitudinal direction of the traverse. The transverse beam can be made curved or of another shape, including composite, and, in essence, be located transverse to the longitudinal direction of the traverse. In a particular case, the transverse beam can also be straight, located at a certain acute angle to the longitudinal direction of the traverse.

The arrangement of the beam along the traverse does not restrict the implementation of the beam to only a straight beam located parallel to the longitudinal direction of the traverse. The longitudinal beam can be made curved or of another shape, including composite, and, in essence, be located along the longitudinal direction of the traverse. In a particular case, the longitudinal beam can also be straight, located at a certain acute angle to the longitudinal direction of the traverse.

Flexible loop sling 4 instead of a hook, as in the prototype, contains a loop that is hooked with the basket eye when using a traverse. Flexible loop sling can be made:

in the form of a textile or rope sling with two loops at the ends for their engagement, respectively, with the bracket 3 of the traverse and the eye of the basket;

in the form of a textile or rope sling in the form of a ring-loop (see figure), engaging with the bracket 3 of the traverse and the eye of the basket;

in the form of a chain, equipped at the end with a loop-link (including a link of an increased size compared to the rest of the chain links), a shackle or a textile loop.

Order of use

When lifting the basket with a semitrailer (not shown), the traverse is fixed at the corner fittings 5 located on the frame, on the pin grips of the spreader mechanism (not shown) of the reachstacker (not shown), while flexible loop slings 4, suspended on the traverse brackets 3, enter into engagement with the lugs installed on the basket (not shown).

Industrial applicability.

The claimed utility model is implemented using commercially available devices and materials, can be manufactured at any machine-building enterprise and will find wide application in the field of loading automobile semitrailers onto railway platform wagons.
