Description

DESCRIPTION OF THE INVENTION

Technical sector

[001] The applied invention relates to transport and lifting devices used to move a basket with a car semi-trailer.

Analysis of the prior art

[002] One of the methods of cargo delivery is container transportation - combined car semi-trailer combined rail and car transportation, in which the car semi-trailer travels part of the way on a railway wagon-platform. Special devices can be used for placing the semi-trailer on the wagon platform - baskets, which also serve to move the semi-trailer from the wagon platform.

[003] From RU invention patent 2675745, IPC B61D 47/00 B66F 7/02, publ. 24.12.2018, [1], a lifting device is known, with the help of which, using clamps on the side beams, the basket is removed from the wagon - platform and placed on the ground surface.

[004] A lifting device is also known (European patent EP 2902299, AI, IPC B61D 3/18; B61D 47/00; B61J 1/10; B65G 63/00; B66C 1/28; B66F 7/24, publ. 05.08 ,2015, [2] containing lifting straps with handles.

[005] In addition, for lifting baskets with semi-trailers, specialized forklift trucks are used, which are equipped with special equipment - the bottom gripper "piggy back" (K)prm ПетроΒ, «PnucTaKepLi - norpy3HHKH o6pa6oTKH KOHTeŪHepoB» in the magazine «CKnņn π TexHHKa», N°l-2006. The magazine is registered in the KF Press Committee, certificate PI N°77—16221, published on the Internet https://sitmag.ru/article/9988-richstakery-pogruzchiki-dlya-obrabotkikonteynerov, hereinafter - [3]).

[006] The use of the lower "piggy back" grippers for lifting baskets with a semi-trailer has the following drawback. The "piggy back" handles are fixed to the basket's lugs using a significant side pressure force. Therefore, the design of the basket must also be adapted to the specified compressive force, which, taking into account other loads acting on it (gravity of a loaded semi-trailer, longitudinal loads when transporting the basket in a wagon), which causes an increase in the tare mass of the basket, and accordingly causes the transportation of a basket with a semi-trailer by railway price increases due to the increased tariff rate.

[007] Travers with flexible slings do not have this drawback. In such traverses, the grippers (for example, hooks) are fixed to the ridges of the basket due to the mutual adhesion of the grippers and loops, by tensioning the slings.

[008] As the closest known solution of the technical level, a traverse basket for moving a car semi-trailer has been chosen, which includes longitudinal beams, side beams, sockets located on the beams for inserting hook-shaped lifting rods into them, and in addition, the longitudinal beams and side beams form a rectangular frame, in the corners of which large tonnage are installed container corner fittings (RU patent for utility model 193221, IPC B66C 1/68, publication 17.10.2019, [4]).

[009] Such a traverse is compatible with a forklift [3].

[010] The longitudinal and transverse distance between the corner fittings on the crossbar to ensure compatibility with the loader (rich stacker) is regulated by normative documents, for example, GOST R 53350-2009 [5],

[011] In order to prevent the risk of damage to the semi-trailer body by the hook lift bars during loading and unloading operations, a sufficient distance between the semi-trailer body and these lift bars must be provided using the traverse. Accordingly, the transverse distance between the hook lift bars must be greater than the width of the semi-trailer body, which in turn is greater than the transverse distance between the crossbar corner fittings.

[012] In the thus indicated closest state-of-the-art solution, due to the location of the corner fitting stops in the corners of the crossbar, the width of the crossbar is insufficient to place the hook-shaped lifting bars for the attachment points with the possibility of providing the necessary space between the hook-shaped lifting bars and the semi-trailer body.

[013] This problem can be solved by placing the hook-shaped lifting bar attachment points on the external brackets, however, in this case the strength of the traverse frame is reduced due to significant bending moments associated with the emergence of the shoulder from the vertical force when the basket with the semi-trailer is lifted.

Outline of the invention

[014] A technical problem, the solution of which is provided by implementing or using the invention, is the need to increase the distance between the attachment points in order to ensure the necessary space between the hook-shaped lifting rods and the body of the semi-trailer.

[015] The technical task, the solution of which is directed to the invention, is to increase the safety (resilience) of the semi-trailer during loading and unloading operations using a traverse.

[016] The technical result provided by the invention is to provide an increased distance between the hook-shaped lifting rods, which reduces the risk of damage to the semi-trailer body.

[017] The specified technical result is achieved due to the fact that the traverse basket for moving with a car semi-trailer, which includes longitudinal beams, side beams, sockets placed on the beams for inserting hook-like lifting rods and fittings for connecting to the loader (reach stacker) gripping mechanism, in addition, longitudinal and side beams form a frame, characterized by the fact that the fittings for connecting to the loader's grip mechanism are placed on the side beams, while the sockets for inserting the hook-shaped lifting bars are placed on the longitudinal beams.

[018] With this arrangement of fittings, the width of the traverse, along the side beams, can be such that the necessary distance between the attachment points of the hook-shaped lifting bars is provided, at which there is no risk of damaging the semi-trailer body during loading and unloading operations.

[019] Thus, compared to the nearest state-of-the-art solution, using a crossbar provides the necessary clearance between the hook suspensions and the semi-trailer body, as a result of which there is no risk of damage to the semi-trailer body during loading and unloading operations.

[020] Consequently, the applied invention differs from the closest prior art solution in that the fittings for connecting to the loader's gripping mechanism are placed on the side beams.

brief description of the drawings

[022] The drawing shows an overview of a traverse basket with a car semi-trailer for moving.

[023] The invention is explained with graphic material, where the drawing shows an overview of a crossbar, a basket with a car semi-trailer for moving, which includes longitudinal beams (1), side beams (2), sockets placed on the beams (3), hook-shaped lifting bar (4) for inserting and connecting the fittings (5) to the loader (reach stacker) gripping mechanism, in addition, the longitudinal members (1) and the side beams (2) form a frame characterized by the fact that the fittings (5) for connecting to the loader's gripping mechanism are placed on the side beams (2) .

[024] Implementation of the technical solution.

[025] Traverse basket with car semi-trailer for moving (see drawing) contains longitudinal beams (1), side beams (2). Brackets (sockets) (3) for inserting hook-shaped lifting rods (4) and fittings (5) for connecting to the loader's gripper mechanism are placed on the longitudinal beams (1). The side beams (1) and the side beams (2) form the frame, and the fittings (5) for connecting to the loader's gripper mechanism are placed on the side beams (2). In this case, the location of the fittings (5) on the side beam (2) means that the fittings (5) can be attached to the surface of the side beams (2) and can also be fully or partially located in these side beams (2). The frame is mostly made rectangular, but it can also have another shape.

[026] In this case, the position of the side beam (2) across the traverse does not limit the realization of the beam only as a straight beam located perpendicular to the longitudinal direction of the traverse. The side beam (2) can be made curved or other shapes, including composite, and is essentially transverse to the longitudinal direction of the cross member. In some cases, the side beam can also be straight and located at a certain narrow angle to the longitudinal direction of the traverse.

[027] The arrangement of the beam along the traverse does not limit the realization of the length (1) only as a straight beam located parallel to the longitudinal direction of the traverse. The girder (1) can be made curved or other shapes, including composite, and is basically located in the longitudinal direction of the traverse. In some cases, the length can also be straight, located at a certain narrow angle to the longitudinal direction of the traverse.

[028] Procedure for use.

[029] When lifting a basket with a semi-trailer (not shown), the traverse is fixed behind the fittings (5) located in the side beams (2) on the pin grabs (not shown) of the loader (not shown) gripper mechanism (not shown), while the hook lifts the bars (4) located on the transverse longitudinal beams (1) are connected to the lugs mounted on the basket (not shown).

[030] Industrial use.

[031] The applied invention has been implemented using industrially produced devices and materials, can be produced in any engineering company and will find wide application in the field of loading car semi-trailers on railway wagons - platforms.
