Description

The invention relates to devices installed along railway tracks to protect against noise, and can be used to protect the territory of residential buildings adjacent to the cargo yard from noise arising during cargo operations.

A device for noise protection is known, containing internal and external screens and acoustic panels connected to support posts, installed on a support base at a certain interval (patent RU 2400595, 06/15/2009). According to a well-known solution, a base is made in the form of a point foundation for each support post.

The disadvantages of the known solution include the difficulty of using it when performing cargo operations, since the device is stationary and can interfere with the supply of lifting and transport equipment to the cars.

The design of a wall noise-absorbing fence for railways and its use as a noise-absorbing screen or barrier that prevents passage is known, containing at least several fencing elements placed sequentially end to end relative to each other, hingedly connected with the possibility of tilting the fencing elements down from the vertical provisions (pat. RU 2550772, 07.26.2011). According to a known solution, the fencing elements are located within the maximum width of the cars or cargo space of the rolling stock with the possibility of their overturning using hinged sections below the car or cargo, which is below the standard position and/or is oversized.

The disadvantages of the known solution include the difficulty of supplying handling equipment to cars when using it.

The closest, in terms of the totality of essential features, - the prototype of the claimed invention - is a mobile platform with a gap compensation device, including a fixed part and an associated moving part, made of a metal frame with the possibility of reciprocating movement relative to the fixed part (patent FR 2987383, 24.02 .2012). According to a well-known solution, the movable part rests on the fixed part, and its movement is carried out using actuators. During operation, the stationary part of the device is separated from the object being serviced by a partition made of a metal frame and connected to the stationary part with the ability to rotate relative to the stationary part and then lay it on it.

The disadvantages of the known solution include, firstly, the absence of means on the partition for creating an acoustic shadow on the side opposite the car, secondly, the impossibility of moving the partition along the long side of the fixed part and, thirdly, the complexity of the design due to the presence of special actuators for bringing the device into working position.

The technical problem to be solved by the proposed invention is the development of a portal-type mobile noise barrier screen (hereinafter referred to as the screen) for use during cargo operations on the railway.

The technical result of the implementation of the proposed invention is to effectively protect the territory of a railway station from noise arising during cargo operations.

The solution to the stated technical problem is achieved by making a moving part of the screen, including a fixed part and an associated moving part, made of a metal frame with the possibility of reciprocating movement relative to the fixed part, in the form of a longitudinally symmetrical spatial truss structure mounted on the fixed part on rollers supports, and making a fixed part in the form of rail guides, located in pairs on both sides relative to the plane of symmetry, with placement on the moving part on each side relative to the longitudinal plane of symmetry of two planes of noise-proof panels in a moisture-resistant shell, one of the planes in which the noise-proof panels are placed , is located vertically, and the second is oblique relative to the first.

What is new in the proposed screen is its implementation in the form of a spatial truss structure, installed with the possibility of longitudinal movement manually on roller supports on rail guides located in pairs on both sides of the rolling stock being processed.

This feature is new, significant, industrially applicable and aimed at achieving the stated technical result.

The screen proposed as the present invention is illustrated by drawings.

Figure 1 shows a general view of the proposed screen.

Figure 2 shows a fragment of the proposed screen with a rollover safety device installed on a roller support.

Figure 3, as an example, schematically shows the proposed screen installed above the car.

The positions indicate:

1 - screen frame,

2 - noise protection panels,

3 - roller bearings,

4 - safety device against turning over,

5 - farms,

6 - rail guides,

7 - carriage,

8 - lifting and transport device.

The frame of 1 screen is made of standard steel profiles.

The screen has a collapsible design: noise protection panels 2 are placed in a moisture-resistant shell, located on each side relative to the longitudinal plane of the screen - the plane of symmetry - in two planes, one of which is located vertically, and the second is inclined relative to the first, and is attached to the frame with bolts through connecting plates.

Roller bearings 3 are equipped with safety devices against turning over.

The use of rail guides 6, laid in pairs on both sides of the longitudinal plane of the screen, allows, in addition to the safety device 4 against overturning, to increase the stability of the structure against overturning.

The use of double rows of noise protection panels 2 on each side of the symmetry plane increases the effectiveness of noise protection.

The upper part of the screen does not have noise protection panels 2, which allows cargo operations to be carried out using a lifting and transport device in the spaces between the trusses 5.

Designs of screen elements not disclosed in the application materials are known and are not subject to patent protection. The proposed screen works as follows.

The car 7, with which it is necessary to carry out cargo operations, is delivered to the place where these operations are performed, where rail guides 6 are previously laid on each side of the track on which the cars will be located.

After the car 7 takes its place, the screen is manually rolled up to it along the rail guides 6.

The lifting and transport device 8 is lowered inside the car between the trusses 5 and loading or unloading is performed.

After completing cargo operations with one car 7, the screen is rolled to the next car.
