SU1573211A1 - Bunker-train - Google Patents

Abstract

The invention relates to a lifting and transport machinery and is aimed at improving the reliability of the bunker-train by eliminating the spillage of the transported material. The bunker train contains sections supported by ends on the undercarriage 4 by means of ball bearings. The sections are provided with contours 5 with a tape 8. The carriages 4 have racks 10, to which walls 11 are attached, having vertical and inclined parts. The ends of the walls 11 are located above the ends of the sections. When the belt 8 moves, the outlines of the hearth 5 move the mass to the place of unloading. When the bunker train moves, the sections rotate around the hinge 9. In this case, a relative rotation of the guide walls 11 relative to the ends of the sections takes place. 4 il.

Description

FIG. 2

This invention relates to a lifting machinery industry, in particular to train hoppers intended for transporting bulk materials.

The purpose of the invention is to increase the reliability of the train bunker by eliminating the spillage of the transported material.

1 shows a bunker train, a general view; figure 2 - node I Lig.1; FIG. 3 shows the mating of two cars, top view without a conveyor belt; figure 4 - section aa on fig.Z.

The bunker train consists of a head section 1, an intermediate section 2, an end section 3, with its ends resting on the undercarriage carts 4, while the adjacent intermediate sections rest on a common carriage.

All sections are equipped with closed drive circuits 5, which may include a belt conveyor, a chain conveyor, etc. The closed drive support loop 5 of each section has a tension 6 and autonomous reversible drive 7 drums. A conveyor belt 8 is placed on the drive closed support contours, wound mostly on the drive support contour of the head section.

The ends of the tape are attached to the tape (chain) of the closed drive circuits of the head 1 and end 3 sections. On each of the intermediate running carriages 4, there are two spherical hinges 9 rigidly connected to the ends of the section bodies. Trailer running carts have one similar hinge. On intermediate running carriages 4 vertical racks 10 rigidly fixed to the frame are placed; trolleys symmetrically located relative to the vertical longitudinal plane along the side walls of the cars. Cylindrical 12 and conical 13 directions are placed directly on the vertical racks 10 directly angled profile respectively, mounted on vertical and inclined walls, with the axis, on which lie the centers of the cylindrical and conical surface it guides, passes through the center of the hinge 9.

At the ends of the side walls of the sections 1 and 2, supported by the intermediate carriages 4, there are also cylindrical 14 and conical 15 guides, mounted respectively on the vertical and inclined parts of the side walls. The axes on which the centers of the cylindrical and conical surfaces of the guides lie also pass through the centers of the hinges 9, while the radii of curvature of the cylindrical 12 and conical 13 surfaces of the guides located on the shield are equal to the radii of curvature of the respective surfaces of the guides located on side stacks of wagons. A support 16 is placed between the vertical drains 10, rigidly connected with them and provided with low-friction guides 1 7. There is a gap between the support 16 and the ends of the sections.

Bunker train works as follows.

The belt 8, loaded with rock mass, while rotating the drums 7 of the driving support loops 5, moves along the train hopper and moves the rock mass, while the belt 8 is wound onto a closed section support loop located at the opposite end from the loading point.

On the rounded paths, the sections rotate around the hinge 9. This results in interaction and relative rotation of the cylindrical 12 and conical 13 guides fixed on the walls in the cylindrical 14 and conical 15 guides placed on the ends of the side walls of the sections.

The presence of a hinge installation of adjacent sections on a common carriage does not lead to their lateral displacement, but only to the angular one, which is more beneficial especially for tape operation 8. Existence of vertical posts rigidly mounted on the frame of the carriage, symmetrically located relative to the vertical longitudinal plane of the carriage along the side walls cars and having an angular profile of a wall which are fixedly connected with them, on both ends of which cylindrical guides are mounted relative to a stand on a vertical wall, and on inclined th wall - the conical guide interacting with

corresponding cylindrical and conical guides on the side walls of the cars, makes it possible to reduce the lateral spillage between sections, as well as efforts to overcome the resistance to movement of the rock mass within the intercarriage space.
