RU62072U1 - DEVICE FOR FASTENING LONG-LINE RAILS ON THE RAILWAY PLATFORM - Google Patents

Abstract

The utility model relates to the field of railway transport, and in particular to devices for placing and fastening rails 50-100 m long when transporting them on the hooks of railway platforms. The purpose of the utility model is to reduce metal consumption and simplify the design, increase the reliability of fastening of long loads. The device consists of one forming support and restrictive supports mounted on the coupling platforms and made in the form of frames. In this case, the forming support is placed on one of the central platforms of the coupler and placed in the plane passing through the transverse axis of the platform. Restrictive supports are placed on the remaining platforms of the coupling, in accordance with the calculation of the loads on the platform trolleys. The formation of rails in packages is carried out by laying the rails on the sole close to each other over the entire width of the support frames, in four rows in height. Between the rows, gaskets are installed with end plates preventing the gaskets from exiting the rail package when the coupling moves. The package of rails is rigidly fixed on one platform, in the forming support, with clamping beams, which are fastened with screws to the vertical posts of the support, tightly pressing the package to the base of the support, eliminating the possibility of longitudinal and transverse movements. The package is not fixed on the rest of the towing platforms, in the restrictive supports, and the rails have the possibility of longitudinal and transverse (limited) movement along the axles of the coupling when passing curved sections of the track.

Description

The utility model relates to the field of railway transport, and in particular to devices for placing and fastening rails 50-100 m long when transporting them on the hooks of railway platforms.

A device is known for fastening long rail rails on the coupling of railway platforms (USSR author's certificate No. 1614979 B 60 P 7/12, E 01 B 29/17, Bull. No. 47, 1990), consisting of two central mounting and peripheral supports made in the form of frames opened on top. On the side racks of the central frames, horizontal supports are fixed in the form of rows of support rollers on the axis, removable cross members with a calibrated locking and clamping device for fixing the upper tier of the rails are installed. The peripheral frames have vertical rollers with a drive for moving them, rollers of horizontal bearings in the form of a shaft - gaskets, including supporting rings mounted on thrust bearings.

The disadvantages of this device are:

- large metal consumption;

- complexity and high manufacturing costs (all components and parts, except bearings, are performed manually);

- a large number of redundant connections and connections, which reduces the operational reliability of the device;

- difficulty in monitoring, at inspection points, the working condition of the fasteners of the supports inside the rail package, which can lead, if one or two parts are broken, to violate the integrity of the package.

The purpose of the utility model is to reduce metal consumption, a significant simplification of the design of the device in the manufacture and

operation, while ensuring safe transportation of rails 50-100 m long on the hooks of railway platforms.

This goal is achieved by the presence of the following significant distinguishing features:

- reduction of metal consumption (the use of the least number of grades and assortment of metal and scarce materials);

- simplicity of construction in manufacture (use of unified and standardized units and parts, minimum parts subject to machining);

- lack of excess connections and a minimum of threaded connections;

- simplicity of the device in operation;

- the ability to monitor the working condition of the device and the cargo carried during transportation.

The significance of the distinguishing features of the utility model is confirmed by the following:

- the use of standard profile steel, the absence of scarce materials, a minimum of parts subject to mechanical processing reduces metal consumption and simplifies the design of the device, significantly reduces production and operating costs;

- the absence of excessive connections and connections increases the operational reliability of the device;

- the simplicity of the designs of the supporting frames allows you to monitor the working condition of the device at the points of inspection, in the process of transportation of goods.

The essence of the utility model is illustrated by drawings.

Figure 1 shows the layout of the supports and the package of rails on the coupler of four universal platforms; figure 2 - forming support; figure 3 - clamping beam forming support

figure 4 - restrictive support placed in it a package of rails of type P-65.

A device for mounting on the coupling of railway platforms long rails 1 (Fig. 1), mounted on soles in horizontal rows of four tiers in height, contains supports fixed to the platforms 2, made in the form of vertical transverse frames and a set of multi-turn gaskets 5.

One support (forming) 3 is mounted on one of the central coupling platforms in the plane of the transverse axis of the platform. The support is made of rolled steel and serves to transfer vertical and horizontal loads from the weight of the load and inertial forces to the platform floor through two transverse beams, uniformly across the width of the platform. Four vertical racks of the frame, preventing the lateral displacement of the rail package, are made of a channel facing the shelves inward, welded to the transverse beams, and reinforced from the outside with “scarves” made of sheet iron. The clamping beams are attached to the vertical posts using screws, which ensure reliable fastening of the rail package from longitudinal displacement by tightly pressing the package to the transverse beams. Cross beams, vertical racks and clamping beams are reinforced with wooden bars. The width of the working surface of the forming support is equal to the width of the rail package.

Restrictive supports 4 are installed on the remaining platforms of the coupling, in places determined by the calculation of the loads on the platform trolleys. The supports are made of rolled steel and are used to transfer the vertical load from the weight of the cargo to the platform floor through one transverse beam, and for limited movement of the rail package across the platform when the coupling is inserted into a curved section of the track. Two vertical posts are welded to the transverse beam, made of a channel facing the shelves inward, reinforced

braces and “scarves” of sheet iron. The crossbeam and uprights are reinforced with wooden blocks.

Multi-turn gaskets 5 are made of a wooden bar reinforced with a metal strip. Metal plates are welded along the ends of the gaskets to prevent the gaskets from escaping from the rail package when the coupler moves.

The device operates as follows.

A package of rails of the R-65 type is assembled on a coupler in four rows of fourteen rails in each row. All rails in the package are mounted on the soles. Multi-turn gaskets 5 are installed between the rows of rails and in the plane of the forming and limiting supports. The rails package 1 is mounted on one platform, in the forming support 3, with clamping beams, which are tightly pressed with screws to the upper row of rails. Four vertical posts and pressure beams of the forming support rigidly fix the rails in the package, eliminating the possibility of their longitudinal and transverse movement. On the remaining platforms of the coupler, in the restrictive supports 3, the package is not fixed and the rails in the package have the possibility of longitudinal and transverse movement along the axes of the coupler.

With a length of rails of 50 m, the coupler consists of four universal platforms, the forming support is one, the bounding supports are five.

With a rail length of 100 m, the coupler consists of seven universal platforms, the forming support is one, the limiting supports are twelve.
