Description

The invention relates to the field of transport construction and can be used for the construction and reconstruction of the railway track, restoration work to eliminate the consequences of emergencies, as well as for transportation and unloading of building materials and other works on the railway in cramped conditions.

There is a method of unloading and loading of goods during emergency recovery and repair and construction works of the railway track (Gritsyk V.I. Construction of railways: Textbook - M .: UMK MPS of Russia, 1999. - 384 p. S.193).

The method includes delivering cargo to the place of unloading with the help of a freight train, including several railway platforms with cargo and a locomotive, unloading it with a jib crane on a railway running on a nearby track.

The method is as follows.

After the freight train arrives at the unloading site, the jib crane unloads the railway platform located in the crane operating area, after unloading this platform, the locomotive moves the following platforms to the crane operating area.

The method allows to unload large volumes of goods and thereby reduces the duration of the technological "window".

The disadvantages of this method is the need for a second path located within the operating area of the crane, which makes it impossible to use the method on single-track sections, as well as the practical impossibility of simultaneously loading other goods from the slope, which is extremely important during emergency recovery work.

The closest in technical essence and the achieved result is a method of unloading and loading of goods during emergency recovery and repair construction works of the railway track (L.L. Olenichev, V.I. Filippov, Yu.F. Veikov, P.A. Skvortsov, GI Dovzhenko. Construction of Railways: Textbook. - M.: Military Publishing House, 1989. - 418 p. S.309).

The method includes delivering cargo to the place of work using a train consisting of a locomotive, a jib crane on a railway track and a platform with tare units mounted on it with cargo coupled to a crane, and unloading the cargo by a crane onto a curb, slope or territory near the railway .

The method is as follows.

After the locomotive delivers the jib crane and the railway platform coupled to it with the tare units mounted on it with cargo to the unloading place, the jib crane unloads the tare units onto the curb, slope or territory near the railway track.

Since the crane radius does not allow unloading more than one platform, after unloading the platform, it is sent to the nearest station, where it is exchanged for loaded and the process is repeated.

The advantage of this method is the possibility of subsequent loading of goods from the curb onto a platform freed from cargo.

The disadvantage of this method is the decrease in the efficiency of time use of the technological “window” and the increase in the time of work. This is due to the fact that one railway platform is not enough to deliver the required volume of cargo to the unloading place and therefore it is necessary to constantly exchange an empty platform, sending it to the station, to the platform with cargo, which increases the time of work and thereby reduces the efficiency of using the technological “window” time ".

A device is also known for unloading and loading goods during emergency recovery and repair construction works of a railway track (L.L. Olenichev, V.I. Filippov, Yu.F. Veikov, P.A. Skvortsov, G.I. Dovzhenko. Construction of Railways: Textbook. - M.: Military Publishing House, 1989. - 418 p. S.309).

The device comprises a locomotive, a jib crane on a railway track and railway platforms coupled to it, tare units for cargo with sling loops placed on a railway platform.

The device operates as follows.

The locomotive delivers a jib crane with platforms and container units mounted on one of the platforms with cargo to the unloading place, where the container unit is unloaded to the side of the road, then, if there is a need to load cargo from the side of the road, it is loaded into an empty container unit, which is installed by crane to the platform, and then transport.

The device allows for both unloading cargo and loading cargo from the curb.

The disadvantage of this device is that when using tare units, their number and, therefore, the amount of unloaded cargo is limited by the radius of the crane, therefore, to deliver the required volume of cargo, it is necessary to exchange empty tare units for tare units with cargo at the loading point, which leads to an increase in time work and thereby reduces the efficiency of time use of the technological "window".

The problem solved by the invention is to create a method of unloading and loading of goods during emergency recovery and repair and construction works of the railway track and a device for its implementation, allowing to increase the volume of unloading and loading of goods at the railway track during the allocated technological "window" and thereby increasing the efficiency of using the technological “window” time.

1. To solve the problem in the method of unloading and loading of goods during emergency recovery and repair and construction works of the railway track, including the delivery of goods to the place of work using the train, consisting of a locomotive, a jib crane on the railway track and platforms installed on them in tare units with cargo attached to the crane, and crane unloading the goods to the curb, slope or territory near the railway track, unloading of goods is carried out by a jib crane from close the platform of the train, attached to the crane on the one hand, as tare units with cargo are distributed across the entire length of the train, and return loads are loaded into the same tare units and installed on the nearest platform of the train from empty platforms, coupled with a jib crane on the other hand, and as this platform fills, the tare units with the load are shifted to other empty platforms, or in the absence of return loads, unloaded tare units forcibly relocated jib crane to the nearest train platform, located on the other side of the crane, and stack them.

Distinctive features of the proposed method from the prototype are the unloading of cargo from container units located on the platforms of the train, coupled to the crane on the one hand, the promotion of container units with goods into the crane operating area, loading of return cargo into vacated container units and installing them on the platform of the train from empty platforms, coupled to the crane on the other hand, or stacking the freed packaging units onto the train platforms from empty platforms.

2. In a device for unloading and loading goods during emergency recovery and repair construction works of a railway track containing a locomotive, a jib crane on a railway track and railway platforms connected to it, and container units for cargo with sling loops located on railway platforms, railway platforms are located on both sides of the jib crane, equipped with live rolls and winches installed on the first and last platforms from the jib crane, tare units for cargo and they are made in length multiple of the length of the platform, installed on platforms located on one side of the crane, and are equipped with guides for moving along platforms whose length is at least three times the longitudinal distance between the rollers of the roller table and the hitch for connecting each other and with the winch traction rope, and the train platform closest to the jib crane from empty platforms located on the other side of the crane is equipped with a specially equipped portal for laying and securing the crane boom during transport sorting, the height of which is a multiple of the height of the packaging units in the stack.

Distinctive features of this device are the location of railway platforms on both sides of the jib crane, the supply of railway platforms with roller conveyors, the installation of winch platforms on the first and last of the jib crane, the implementation of container units for cargo lengths that are a multiple of the length of the platform, and the provision of their guides for moving along platforms length at least three times the longitudinal distance between the rollers of the roller table and the hitch for connection between each other and with the winch traction rope, the equipment closest to a jib crane of a train platform from empty platforms with a specially equipped portal for laying and securing the crane boom during transportation.

Due to the distinctive features of the proposed method and device for its implementation, the volume of unloading and loading of goods at the railway track increases during the allocated technological "window" and

the efficiency of using the technological “window” time increases.

The implementation of the method of unloading and loading of goods during emergency recovery work of the railway using the inventive device is illustrated by the schemes shown in figure 1-4.

Figure 1 schematically shows a device for unloading goods on the side of the road, slope or territory near the railway track; figure 2 shows the device in action; figure 3 shows a top view of the platform of the train, equipped with mechanisms for moving container units with cargo; figure 4 - tare unit; figure 5 is a view aa in figure 4.

A device for implementing the method of unloading and loading of goods during emergency recovery and repair and construction works of the railway track comprises a jib crane 1, on one side of which a train platform 2 is attached, on which loaded container units 3 are placed, for example pallets, and on the other is empty train 4 for storing unloaded container units 3 or loading return cargo.

The packaging units 3 are equipped with guide elements 5, for example, skis, for moving along the live rolls 6 of the platforms of compositions 2, 4. The guide elements 5 can be made, for example, of metal, plastic, etc., with a cross-sectional profile corresponding to the profile of the roller table 6. there was no longitudinal and transverse tipping of the tare units 3, their length should be a multiple of the length of the platform of the compositions 2, 4, and the length of the guide elements 5 should be at least three times the longitudinal distance between the rollers of the roller table 6.

The packaging units 3, equipped with loops 7 for slinging the load gripping means 8 of the jib crane 1, are additionally equipped with couplers 9 for interconnecting and for securing the traction ropes 10 of the winches 11 mounted on the platforms of the trains 2, 4 coupled to the jib crane 1.

The method of unloading and loading of goods during emergency recovery and repair and construction works of the railway track is as follows: on the rolling tables of 6 railway platforms along the entire length of the train 2 located on one side of the jib crane 1, tare units 3 are installed with the load and connect them together couplings 9, with the exception of the platform located in the area of operation of the jib crane 1. The jib crane 1 unloads cargo from the packaging units 3 to the curb, slope or territory near the railway track from the platforms s located in his work area. There are two possible options: the load is removed from the container unit 3 or the container unit 3 is removed from the platform together with the cargo, from which it is then released in the right place in the vicinity of the railway track. Then, for the hitch 9 of the tare unit 3 located on the next platform of composition 2, the traction rope 10 is attached, with a winch 11, all coupled tare units 3 are moved by the length of the platform. After this, the couplings 9 are disconnected between the tare units 3 located in the zone of operation of the crane, and the unloading process is repeated until the entire composition 2 is completely unloaded.

After releasing from the delivered cargo, the tare units 3 are transferred by a jib crane 1 to the nearest empty platform of the train 4 and stacked on top of each other, forming stack 12. Since the first platform from the crane of the train 4 serves as a cover platform, it is specially equipped equipped portal 13 for laying and securing the crane boom during transportation. The height of the portal is a multiple of the height of the packaging units in the stack. After filling the nearest platform of composition 4, in the crane operating area, with unloaded container units 3, the lower container units 3 of the stacks 12 are connected to each other by hooks 9. Then, by the coupling 9 of the lower container unit 3 in the stack 12, the traction rope 10 is attached, and all coupled are moved with a winch 11 stacks of packaging units 12 to the end of the convoy 4. Then, as the platform of convoy 4, which is within the radius of the crane, is filled with empty containers 3, the process is repeated until all empty containers 3 are fully loaded.

In the presence of return cargo, for example, loose cargo scattered during an accident, damaged sleepers, etc., they are loaded into tare units 3 and released into the operating area of the jib crane 1, which transfers them to the empty train platform nearest to it 4. After filling the nearest platform of structure 4, in the zone of operation of the jib crane 1, the tare units 3 loaded with return cargo are connected by the couplers 9. Then, the tow rope 10 is fastened to the hitch 9 of the tare unit 3. and winch 11 move all the coupled container units 3 to the next platform of composition 4. Then, as the platform of composition 4, which is within the radius of operation of the jib crane 1, is filled with new loaded container units 3, the process is repeated until all platforms of composition 4 are fully loaded.

Thus, the inventive method of unloading and loading of goods during emergency recovery and repair and construction work of the railway track and a device for its implementation can increase the volume of unloading and loading of goods at the railway track during the allocated technological "window", reduce the time of the technological "window" for work and thereby solve the technical problem.
