Abstract

1. The hatch cover of a universal gondola car, consisting of an all-metal carcass that includes a system of longitudinal and transverse beams, sheathing (a sheet of the hatch cover), hinges for fixing the hatch on the spine of the gondola, locking brackets for fixing the hatch in the closed position, brackets for fixation of hides and fastening elements of one or two torsion bars, characterized by the use of locking brackets, which are angles installed at an angle to the axis of symmetry of the lid on the lower surfaces of the front and pop beams with support on the connection node, including the reinforcing scarf, and having a smaller overhang for the front edge of the lid due to the truncated end of the bracket, forming a surface parallel to the front edge of the lid, which allows you to install it on universal gondola cars of dimensions 1-T, 1-VM and 0-VM in a single design without changing the position and replacement of components. 2. The hatch cover of the universal open wagon according to claim 1, characterized in that the longitudinal front beam is made of a bent channel 120 × 75 × 4 with diaphragms welded into it and together with the sheathing sheet forms a closed section.

Description

The utility model relates to railway transport, in particular to universal universal gondola cars with hatches in the floor of the body, and relates to body manhole covers for unloading bulk cargo loaded from above. The proposed utility model can be used in serial production of trunk universal gondola cars of dimensions 1-T, 1-VM and 0-VM with hatches in the floor of the body and in the manufacture as spare parts for replacing covers for overhauls of gondola cars.

The proposed manhole cover consists of an all-metal frame, sheathing (sheet of the manhole cover), hinges for fixing the manhole cover to the spinal beam of the gondola, locking brackets for fixing the manhole cover in the closed position, brackets for fixing the shrouds, and fastening elements for one or two torsion bars.

The hatch frame includes a system of longitudinal and transverse beams. The longitudinal front beam is made of a bent channel channel 120 × 75 × 4 with diaphragms welded into it, the longitudinal middle beam is made of a symmetrical omega-shaped profile, the longitudinal rear beam is a corrugated sheet with a periodic profile. Cross beams represent an asymmetric omego-shaped profile strengthened by a corner.

The connection of the transverse beams with the front beam is reinforced with scarves made of sheet metal.

The locking brackets are angles and are installed at an angle to the axis of symmetry of the cover on the lower surfaces of the front and transverse beams with support on the connection node, including the reinforcing scarf. In order to be able to install a manhole cover on a 0-VM gondola, the locking brackets have a smaller overhang beyond the front edge of the cover due to the truncated end of the locking bracket forming a surface parallel to the front edge of the cover.

In the Russian Federation, in the CIS countries, Latvia, Lithuania and Estonia, gondola car hatch covers [1], known from the prior art, which are pivotally hinged to the spine beam, are widespread and widely used, they block rectangular unloading body hatches and are fixed with locking devices.

The well-known modern hatch cover [2] of a universal open wagon includes a rectangular flooring, locking brackets interacting with locking devices, and several longitudinal and transverse elements that reinforce the rectangular flooring, which are omega-shaped in cross section. The manhole cover also contains hinge hinges rigidly connected with rivets to a rectangular flooring and with its longitudinal reinforcing element. The cover is used in serial production of trunk universal gondola cars of dimensions 1-T and 0-VM with hatches in the floor of the body and in the manufacture of spare parts for replacement of covers for overhauls of gondola cars.

The disadvantages of the known design of the hatch as a mass assembly unit of a universal open wagon [2] are:

- the manufacture of different versions of the hatch, for installation on universal gondola cars of dimensions 1-T and 0-VM, which differ in the position of the locking brackets and the installation or absence of an additional longitudinal element of the front beam;

- readjustment of equipment during the transition of production between versions of the hatch;

The objective of the proposed utility model is to improve the design of the manhole cover, aimed at reducing and simplifying assembly operations, reducing the complexity of work on the readjustment of equipment in the manufacture of manhole covers for the assembly of gondola cars of different sizes.

The technical result of the utility model “Universal open wagon hatch cover” is the reduction in the cost of serial production of hatch covers, a significant reduction in the cost of technological preparation of production, and an increase in labor productivity.

To achieve a technical result, in the proposed manhole cover consisting of an all-metal frame, sheathing (sheet of the manhole cover), loops for securing the manhole cover on the spinal beam of the gondola, locking brackets for fixing the manhole cover in the closed position, brackets for fixing the shrouds, and fixing elements of one or two torsions, locking brackets are angles that are mounted at an angle to the axis of symmetry of the cover on the lower surfaces of the front and transverse beams with support on the connection node, including on the reinforcing scarf and have a smaller overhang beyond the front edge of the cover due to the truncated end of the locking bracket forming a surface parallel to the front edge of the cover.

Brief Description of the Drawings

Figure 1 is a General view (side view) of the hatch cover of a universal open wagon in a working position. The dimensions of the profile of the front beam, the hinges of the hatch cover to the spinal beam of the gondola car frame are shown.

Figure 2 - view a in figure 1 (view of the hatch from the bottom). Shown are sheathing (hatch cover sheet), transverse beams, front beam, middle longitudinal beam, rear beam, locking brackets, reinforcing scarf, truncated end of the bracket.

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

The manhole cover, Figs. 1 and 2, is 1/14 of the flat metal floor of the body of a universal open wagon. The flat floor is made of 14 manhole covers (seven on each side of the spinal beam). In the lowered (open) state, each manhole cover rests on the stops welded to the transverse beams of the frame, located at an angle of 31 ° to the horizontal for unloading bulk goods.

The proposed manhole cover consists of an all-metal frame, sheathing (sheet of the manhole cover) 1 of Fig. 2, hinges of 6 of Fig. 1 for fixing the manhole cover on the spine beam of the gondola, locking brackets 7 of Fig. 2 for fixing the manhole cover in the closed position, brackets for fixing zakidok, and fastening elements of one or two torsion bars.

The hatch frame includes a system of longitudinal and transverse beams. The longitudinal front beam 3 is made of a bent channel channel 120 × 75 × 4 with diaphragms welded into it, the longitudinal middle beam 4 is made of a symmetrical omega-shaped profile, the longitudinal rear beam 5 is a corrugated sheet with a periodic profile. The transverse beams 2 are an asymmetric omega-shaped profile reinforced by a corner.

The connection of the transverse beams with the front beam is reinforced with scarves 8 made of sheet metal.

The locking brackets 7 are angles and are mounted at an angle to the axis of symmetry of the cover on the lower surfaces of the front and transverse beams with support on the connection node, including the reinforcing scarf 8 and have a smaller overhang beyond the front edge of the cover due to the truncated end "B" a bracket forming a surface parallel to the front edge of the cover.

The applicant organization has developed working drawings of the manhole cover, proposed as a utility model, and it is planned to develop its production at Svesky Pumping Plant PJSC for use in serial production and repair of universal gondola cars of sizes 1-T 1-VM and 0-VM.
