Description

The proposed utility model relates to devices for collecting unusable sleepers from the slopes of a railway track, loading them onto a platform, and transporting them.

When repairing a railway track, a large number of sleepers are rejected due to various deviations from regulatory documents.

For example, with an average repair of only 1 km of a railway track, up to 500 or more sleepers are culled. As a rule, rejected sleepers are placed on the slopes of the railway track.

Currently, the collection of rejected sleepers is in most cases carried out manually.

The well-known hydraulic manipulator LV 185-14 installed on various base vehicles: Ural, KamAZ, KrAZ, MAZ (Promotional brochure for the 65th anniversary of the Maykop Engineering Plant "Technics for Professionals" website www.mayman.maykop.ru).

The hydraulic manipulator is installed at various bases (cars, tractors, sea and river transport, stationary).

The hydraulic manipulator includes a column, a rotary support device, an arrow pivotally connected to the column, a system of hydraulic cylinders and control valves for controlling the working bodies.

The boom consists of a main part and a cantilever pivotally connected to the main part; there is a gripping device at the end of the boom.

It is not possible to use this installation for collecting rejected sleepers and dumped on the slopes of the railway embankment, since for this it is necessary to have roads on both sides of the railway, which, as a rule, are not. In addition, such installations

inefficient because do not provide collection of the entire volume of sleepers in one trip.

Known mobile machine for removing rails and sleepers, as well as their transportation to the base (patent OE No. 1340594, registered July 1, 1970, IPC EV 01/09).

The machine is designed to remove rails and sleepers during the dismantling of the railway track. It contains: a casing in the form of a truss on a wheeled track on a rail track, a conveyor for sleepers, at the end the cantilever rests on a trolley. On the trolley there are guides for placing removable rails.

In the middle part of the housing is a device for gripping the sleepers and feeding it to the conveyor.

In the first part of the housing is a motor with a drive to ensure the movement of the machine.

The machine operates as follows. The machine moves along the rails and when the trolley on a caterpillar track reaches the beginning of the rail, it is placed using the device on the trolley.

Then each sleeper is taken by a gripping device, rises and fed to the conveyor. From the conveyor, the sleeper is immersed on a railway platform.

This track repair technology is not applied on Russian Railways, as involves a continuous change of rails and sleepers. With an average repair of the track, the change of sleepers is made selectively (only unusable).

It is not possible to use this mobile machine for collecting sleepers from slopes, since the gripping device can only capture sleepers that are left lying in place after removing the rail.

The closest analogue is a machine for receiving railway sleepers (RF patent No. 2256022, priority July 17, 2002, IPC ЕВВ 29/06).

The machine is equipped with a device for receiving sleepers, which has an endless transport chain with exciting bodies for delivering sleepers to the receiving end of the unit for transporting sleepers.

The transport chain has upper and lower rotary ends, as well as skis for sleepers, designed for continuous immersion in the crushed stone base for laying on them removed sleepers.

Moreover, the transport chain is inclined to the crushed stone base at an angle α, which is less than 90 °, the lower rotary end in front of the upper rotary end.

The cross-country skis are continued by the cross-rail guide extending in the longitudinal direction of the machine and having a transfer end.

In the area of the lower pivot end and above the ski for sleepers, a pusher of sleepers is provided with the possibility of rotation around an axis extending perpendicular to the longitudinal direction of the machine and relative to the lower pivot end using another drive.

The distance between two adjacent gripping bodies of the transport chain is at least twice the width of the sleepers.

The angle formed between the guide for sleepers and the sliding surface of the ski for sleepers is 130-150 °.

The upper end of the rail sleepers has a hinged part that can be rotated around an axis perpendicular to the longitudinal direction of the machine.

The disadvantage of this machine is that it is designed to collect only sleepers that remained lying on the railway embankment after removing the rail, and can not collect sleepers located on the slopes of the railway embankment.

The objective of the proposed utility model is to ensure the collection of a large number of sleepers located on the slopes of the railway embankment and their delivery to the base.

The problem is solved by the use of a mechanized complex. A mechanized complex for collecting and transporting sleepers on a railway, consisting of a motor platform, loading platform, platforms for transporting sleepers, characterized in that a winch with a rope is mounted on the motor platform for pulling cassettes under the sleepers to the hydraulic manipulator, and on a loading platform mounted on a swing beam hydraulic manipulator with tick-borne grip, pneumatic brake for fixing cassettes for sleepers, hydraulic oil station installed below the platform floor level between longitudinal frame beams powered by a motor platform generator. Each cassette consists of two U-shaped struts, interconnected by longitudinal beams. In the lower part of the cassettes there are special rail linings that allow you to fix the cassette with rail fastenings on two longitudinal beams, which are R-65 rails upside down. All platforms of the complex are equipped with rollers for rolling cartridges along the axis of the platforms. Half of the platforms for transporting sleepers are located in front of the motor platform, the other after loading.

The advantages of the proposed mechanized complex for collecting sleepers will be more apparent from the following description and the accompanying drawings, in which:
