Description

TECHNICAL FIELD

The proposed invention relates to a lifting - transportation equipment used to move a bag with a car semi-trailer.

STATE OF THE ART

One of the methods of cargo delivery is counter-trailer transportation - the combined transportation of several semi-trailers by rail-cars, during which the car semi-trailer travels part of the way on the railway platform. To place a semi-trailer in a wagon-platform, you can use special devices - bags, which also serve to transfer the semi-trailer to or from the wagon.

From RF invention patent no. 267574, TPK B61 D 47/00, B66F 7/02 publ. 201812-24 is a well-known cargo lifting device, in which the basket is removed from the wagon-platform and placed on the ground using the staples in the side beams. A lifting device is also known (European patent EP 2902299 A1, TPK B61D 3/18; B61D 47/00; B61J 1/10; B65G 63/00; B66C 1/28; B66F 7/24, publ. 201508-05, having lifting straps with grippers.

In addition, the specialized loaders used for lifting bags with semi-trailers, conveyor loaders, are equipped with special equipment - the bottom gripper "piggy back" (Jurij Petrov's article "Container loaders - loaders for container processing") in the magazine "Sklad i Technika", No. 1-2006. The magazine is registered in the RF Press Committee, certificate PI No. 77-16221, publication on the Internet https://sitmag.ru/article/9988richstakerv-pouruzchiki-dlva-obrabotki-konte\nerov).

The use of bottom grips to lift bags with a semi-trailer has the following disadvantage. The "piggy back" fixation of the grippers to the eyelets of the bag is performed using a high lateral pressure force.

Thus, the design of the bag must be calculated by considering also the specified pressure force, which, taking into account other loads acting on it (gravity of the loaded semi-trailer, longitudinal loads when transporting the bag in a wagon), leads to an increase in the tare mass of the bag, and accordingly causes the transportation of the bag with a semi-trailer by rail price increase due to increased tariff.

Traverses with flexible slings do not have this drawback. In such traverses, grippers (for example, hooks) are attached to the basket eyes due to the mutual engagement of the grippers and the eyes when the slings are tensioned.

There is a known prototype for moving a traverse bag with a car semi-trailer, which has longitudinal beams, transverse beams, and on the beams there are slots for installing hook hangers, the longitudinal and transverse beams form a rectangular frame, the corners of which are fitted with corner fittings for large tonnage containers (RF patent for useful for model 193221, TPK B66C 1/68, publ. 2019-10-17). This traverse is compatible with a container loader.

The longitudinal and transverse distance between the corner fittings of the traverse, in order to ensure compatibility with the container loader, is regulated by normative documents, for example, GOST P 53350-2009.

In order to avoid the risk of hook suspensions damaging the semi-trailer body during loading-unloading operations using a traverse, it is necessary to ensure a sufficient gap between the semi-trailer body and these suspensions. Accordingly, the transverse distance between the hook hangers 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 arrangement of corner fitting supports 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 ensuring the necessary gap between the hook hanger and the semi-trailer body

This problem could be solved by installing the attachment points of the hook hangers on the external brackets, but in this case the strength of the traverse frame would be reduced due to the large bending moments associated with the formation of the vertical force shoulder when the basket with the semi-trailer is lifted.

ESSENCE OF THE INVENTION

A technical problem, the solution of which is provided by the implementation or use of the present invention, is the need to increase the distance between the attachment points of the hook hangers in order to ensure the necessary distance between the hook hangers and the semi-trailer body.

The technical task to be solved using the invention is to increase the safety of the semi-trailer during loading and unloading operations using a traverse.

The technical result is achieved by the invention, where it is possible to increase the distance between the hook hangers, which reduces the risk of damage to the semi-trailer body.

The specified technical result is achieved by a traverse for moving a basket with a car semi-trailer, comprising longitudinal beams, transverse beams mounted on socket beams for accommodating hook hangers, and fittings for connecting to a container loader gripping mechanism, where the longitudinal beams and transverse beams form a frame , the fittings for connection to the container handler's gripping mechanism are installed on the cross beams.

With such an arrangement of fittings, the width of the traverse along the side beams can be such as to ensure the necessary distance between the attachment points of the hook hangers, at which there is no risk of damage to the semi-trailer body during the loading-unloading operation.

Thus, compared to the prototype, by using the traverse, the necessary gap between the hook hangers and the semi-trailer body is created, due to which there is no risk of damage to the semi-trailer body during loading and unloading.

Thus, the claimed invention differs from the prototype in that the fittings for connecting to the container loader's gripping mechanism are located on the cross beams.

The drawing shows a general view of a traverse for carrying a bag with a car semi-trailer.

The proposed invention is illustrated in graphic material, where the drawing shows a general view of a traverse for moving a basket with a car semi-trailer, including longitudinal beams (1), transverse beams (2), mounted on sockets (3) beams for placing hook hangers (4), and fittings (5) which are intended to be connected to the grab mechanism of the container loader, the longitudinal and transverse beams (1) and (2) form a frame, the fittings (5) fixed on the cross beams (2) for connection to the grab mechanism of the container loader are placed on the cross beams (2).

IMPLEMENTATION OF THE INVENTION

The crossbar for moving a bag with a car semi-trailer (see drawing) consists of longitudinal beams (1), transverse beams (2). Slots (3) are located on the beams to accommodate hook hangers and fittings (5) are for connection to the container handler's gripper mechanism. Longitudinal and transverse beams (1) and (2) form the frame, and fittings (5) for connection to the gripper mechanism of the container handler are attached to the transverse beams (2). In this case, placing the fittings (5) on the cross beams (2) means that the fittings (5) can be fixed on the surface of the cross beams (2) and can be completely or partially installed inside these cross beams (2). The frame is preferably rectangular in shape, but may be of other shapes.

In this case, the position of the transverse beam (2) across the traverse is not limited to the fact that the beam can only be a straight beam perpendicular to the longitudinal direction of the traverse. The transverse beam (2) can be curved or have other shapes, including composite shapes, and can be placed substantially transverse to the longitudinal direction of the traverse. In a specific case, the transverse beam can be straight, {fixed with a certain sharp angle in relation to the longitudinal direction of the traverse. Placing the beam along the traverse does not limit the implementation of the longitudinal beam (1) only as a straight beam installed parallel to the longitudinal direction of the traverse. The longitudinal beam (1) can be made curved or of other shapes, including composite, and can be placed substantially along the direction of travel of the traverse. In a specific case, the longitudinal beam can be straight, forming a certain acute angle, with the longitudinal direction of the traverse.

IMPLEMENTATION OF THE INVENTION

When lifting a basket with a semi-trailer (not shown), the crossbar is fixed with the help of fittings (5), which are attached to the cross beams (2) on the container loader (not shown) in the gripper mechanism (not shown), where the hook hangers (4) are located on the longitudinal beams of the crossbar. (1), are hooked onto eyelets mounted on the basket (not shown).
