RU2861457C1RU 2861457 C1RU2861457 C1RU 2861457C1RU-2861457-C1

Abstract

FIELD: transportation. SUBSTANCE: invention relates to the field of transport transportation, transshipment and storage of bulk and loose cargo in flexible containers with a lifting capacity of no more than 20 tons. The invention also relates to methods for simultaneous loading of flexible bulk containers directly into open railway cars (gondola cars) at factory shipping points intended for hopper wagons. A method for simultaneous loading of a flexible container with preliminary inflation in a gondola car, made in the form of a frame mesh with lifting loops and a liner with a loading and unloading sleeve, wherein the container is placed hanging or with partial support on a platform. Before loading, the container is pre-inflated with air with support on the platform. The problem solved by the claimed invention is to create a method for simultaneous loading of flexible containers with a lifting capacity of no more than 20 tons directly into gondola cars without the use of load-lifting (supervised) devices, ensuring a gondola car loading time not exceeding the loading time of hopper wagons. EFFECT: ensuring an efficient, safe and environmentally friendly loading process of bulk materials, minimising cargo loss and environmental pollution. 5 cl, 1 dwg

Claims (5)

  1. 1. A method for the simultaneous loading of a soft container with preliminary inflation in a gondola car, made in the form of a frame grid with cargo loops and a liner with loading and unloading sleeves, in which the container is placed with partial support on a platform, characterized in that before loading the container is pre-inflated with air with support on the platform, while the inflation of the soft container is carried out on a crossbar, the loading sleeve is passed through the bell of the crossbar, and the free end of the sleeve is turned inside out and hooked onto hooks installed on the bell, and the inflation of the soft container is carried out to the stage when the bottom begins to take the shape of a spherical segment.
  2. 2. The method according to paragraph 1, characterized in that the preliminary inflation of the soft container is carried out through a loading sleeve.
  3. 3. The method according to paragraph 1, characterized in that the loading sleeve is joined and pressed against the conical part of the end of the loading leak when lifting the crossbar with the soft container using electric hoists.
  4. 4. The method according to paragraph 1, characterized in that the soft container is raised to the leak, installed at a height sufficient for straightening the soft container.
  5. 5. The method according to claim 1, characterized in that the processes of inflation, loading of bulk cargo and aspiration of dusty air are controlled in a programmable mode.

Description

Field of technology The invention relates to the transportation, handling, and storage of bulk and loose cargo in flexible containers with a carrying capacity of no more than 20 tons. The invention also relates to methods for simultaneously loading flexible, high-capacity containers directly into open railcars (gondola cars) at factory loading hubs designed for hopper cars. State of the art A load-handling crossbeam known from the prior art is disclosed in invention patent RU 2214961 C2, IPC B66C 1/10, B66C 1/68, July 10, 2003, comprising a frame including longitudinal and transverse beams, a housing, and load-handling devices pivotally attached to the frame. Said beams are designed to form a detachable frame that is movably connected to the housing by means of flexible rods that are pivotally attached to the frame and the housing, respectively. The load-handling devices are replaceable and are secured to the outermost crossbeams of the frame by means of re-installable pins passed through through-holes, respectively, that are formed on each outermost crossbeam at predetermined distances from the longitudinal axis of the frame. The housing is a box-shaped structure with a cutout in the top wall to accommodate a lifting device's load hook. The means for connecting to the load hook includes other repositionable pins, each passed through through-holes in the housing's side walls at specified distances from one another. The load crossbar is equipped with a device for locking the relative position of the housing and frame during transport. Load chains can be used as flexible traction rods, and tongs can be used as load-gripping devices. The tong levers can be equipped with handles. However, the specified traverse has limited functionality and low loading intensity. A device for transporting large-capacity containers in gondola cars and other open rolling stock is known from the prior art under patent for utility model RU 203169 U1, IPC B60P 7/13, B61D 3/20, 03/24/2021, comprising a base configured to be installed and secured to the floor of a gondola car, comprising two load-bearing longitudinal beams of triangular cross-section, fitting stops mounted on the load-bearing beams by means of the bases of the fitting stops and configured to secure a large-capacity container in a gondola car, wherein a guide is installed at the base of each fitting stop, one end of which is configured to be rigidly attached to the wall of the gondola car, and the other to the base of the fitting stop. The disadvantages of this device are the difficulty in unloading bulk materials from a gondola car, as well as the low intensity of loading large-capacity containers. The technical conditions for the placement and securing of cargo in cars and containers (TU RZD No. CM-943), approved by the Ministry of Railways of Russia on May 27, 2003, stipulate that flexible, reusable, high-capacity containers are transported in gondola cars in groups of five containers. However, factory bulk cargo loading hubs are traditionally designed for loading hopper cars, which are loaded into four loading hatches in the car roofs through four unloading pipes (spigots) located above them. Moreover, while the number of loading hatches remains constant, their shapes and spacing vary significantly among different types of hopper cars, such as mineral carriers, grain carriers, cement carriers, and others. Therefore, the discrepancy between the number and location of the loading spouts and the number of flexible containers loaded in a gondola car prevents their simultaneous loading and the same loading time as hopper cars. This reduces the efficiency of using large-capacity soft containers due to insufficient loading intensity and increases the costs of additional logistics and technological operations. According to technical specifications, there are various methods for loading soft containers, such as individually on single-position process baskets, cassettes, crossbars, twin mobile electric hoists with crossbars, and in groups on multi-position frames with four or five soft containers per vehicle. As a means of transport, large-capacity soft containers are loaded in gondola cars, on roll trailers, truck trailers, railway platforms, on forklift forks, and suspended. However, loading soft containers on single-position devices does not ensure the required loading intensity or facilitate automation of the loading process. Loading soft containers on multi-position frames does not ensure high-quality, compact loading of soft containers to their full capacity due to the insufficient capacity of the built-in lifting equipment and the impossibility of using sufficient lifting capacity at the loading points due to the improper strength of existing building structures. With these loading methods, soft containers are manually secured to crossbars and frames and delivered under loading leaks, increasing loading time and reducing loading intensity. Loading intensity is also re
