RU76617U1 - UNIVERSAL Gondola car frame with hatchways in the body floor - Google Patents

Abstract

The proposed universal gondola car frame is used in serial production of hatch gondola cars. The frame includes a spinal beam, pivot and transverse hatch beams and a longitudinal I-beam mounted on the spinal beam, bearing rows of paired holder hinges fixed to the wall, designed for hinging with body manhole covers. The frame is characterized in that each paired row-holder loop is made in the form of two rib-like cheeks connected by a diaphragm, the surfaces of which are inclined, and the fixing of the rib-like cheeks and the diaphragm connected to them to the wall of the longitudinal I-beam is made by welding. The diaphragm is made L-shaped and welded to the wall of the longitudinal I-beam profile, at least in the upper part. The utility model increases the productivity of preparatory and assembly work in the serial production of universal open wagons, significantly reduces the complexity of their manufacture.

Description

The utility model relates to railway transport, in particular to universal main gondola cars with hatches in the floor of the body and relates to the design of the frame, mating with manhole covers and body. The proposed utility model can be used in serial production of trunk universal gondola cars of all sizes with hatches in the floor of the body.

In the CIS and Baltic countries, universal open wagon frames [1] with hatches in the floor of the body, containing a spinal beam, pivot and transverse hatch beams, as well as a longitudinal I-beam mounted on the spinal beam, on each side of the vertical wall, have become widespread and widely known from the prior art. which sets the rows of paired loops. The latter are designed for articulating the frame with the covers of the body manholes, while the connections of the paired loops with the wall of the I-beam profile are made riveted.

The universal gondola car frame [1] known from the prior art is laborious to manufacture, since the use of rivet joints for fastening the paired holder hinges to the I-beam profile in serial production, despite the progressive stamped design of the paired hinge, causes a high laboriousness of the frame assembly by preparatory drilling. installation and riveting, which inhibits labor productivity in serial production of gondola cars.

The objective of the proposed utility model of the universal gondola frame with hatches in the floor is to improve the design, aimed at increasing the productivity of preparatory and assembly work in the serial production of universal gondola cars. Technical and economic result - a significant reduction in the complexity of manufacturing the frame due to structural changes in the frame while maintaining the unification of interchangeable covers for gondola cars, which is necessary for repairs under operating conditions.

To achieve this goal, in the proposed frame, which includes a spinal beam, pivot beams, transverse hatch beams and a longitudinal I-beam mounted on the spinal beam, bearing rows of paired hinges on both sides intended for hinging the hatch covers of each body, each paired hinge of both the rows are made in the form of two rib-like cheeks connected by a diaphragm, the surfaces of which are inclined. In this case, the fixing of rib-like cheeks, together with an inclined diaphragm, to the wall of the longitudinal I-profile is made by welding, the diaphragm is made L-shaped and welded to the wall of the longitudinal I-profile, at least in the upper part. The improved design of the frame and twin loops allows the use of covers unified for gondola cars of all sizes

body hatches that must be replaced during major repairs or in case of accidental damage during ongoing repairs in operation.

Implementation of a utility model (device and principle of operation)

The universal gondola car frame according to the proposed utility model consists of a spinal beam 1, Fig. 1 with sockets-stops 2, Figs. 1 and 2, pivot beams 3 with Fridays 4, frontal beams 5 and interhatch cross beams 6. On beams 3, 5 and 6, body walls are installed (not shown in the drawings). A longitudinal I-beam profile is installed on the spinal beam 1 — a beam 7, which carries one row of paired hinges-holders 8 on both sides of the wall “B” for hinging the manhole covers (not shown in the drawings). Each paired loop holder 8 is made in the form of two rib-like cheeks

9, interconnected by a diaphragm 10 with inclined surfaces "B".

The fixing of the cheeks 9 together with the diaphragm 10 to the wall of the I-beam profile (beam 7) is made by welding. The diaphragm 10 is made L-shaped and its upper part is welded to the wall "B". The diaphragm 10 is installed in a paired loop holder 8 with the formation of a gap "G" between the wall and the lower part of the diaphragm, which is necessary for painting the internal cavity, and its inclined surface "B" eliminates the possibility of accumulation of dirt residue on the loop holder. The paired holder hinges, FIGS. 3 and 4, can be made as a stamp-welded method, and a casting method.

During repairs, in operating conditions, the coupled hinges-holders 8 provide the installation of standardized body covers of the gondola car when they are replaced.

The applicant company has developed working drawings of a universal open wagon frame according to the proposed utility model. An experimental verification and the beginning of the use of the utility model in serial production of universal gondola cars of model 12-9790 is planned for May 2008.
