Description

BALLAST CUTTER

The utility model relates to railway transport and relates to track machines and mechanisms ensuring the maintenance of the current track maintenance in terms of cutting off the contaminated asbestos ballast layer and removing weeds from under the rail sole in areas of intense clogging

Known trimmer ballast system Ishchenko / 1 /. All mechanisms of this trimmer are mounted on a platform. The working body is a block of four welded impellers. Using air cylinders, blocks mounted two on each side are lowered from the transport position to the working position on the rail and, as it were, clasp it. When the fan cutter moves, the impellers smoothly step over the sleepers, raking out the ballast from the sole of the rails outward and inward of the track. The disadvantage of this trimmer is that it often spoils sleepers, knocks down anti-theft and also that it takes over.

The operation of removing weeds from under the sole of the rail is also performed by a machine of the type ROM-3/2 /. Rail-cleaning machine ROM-3

consists of a self-propelled biaxial unit with an electric drive-HOUSE of both axes and a four-axis tank weighing 60 m. The unit has a 200 kW diesel generator unit, a control cabin and two trolleys with working bodies / idromonitors /. The disadvantage of the ROM-3 machine is that it requires a large water flow rate / 32 m / h /, and if the dirt in the rail space is located above the bottom of the rails, then the GM-2 snow blower must first pass. The ROM-3 machine requires technological windows for its operation. takes the stage.

and curved lonati. The disadvantage of this lever device is low productivity, due to the fact that it is a kind of hand tool. According to the calculations, this device increases the productivity of manual trimming in 1.6 shza

It often happens that the use of the above machines is impossible. In these cases, the trimming operation is performed manually using shovels of picks, crowbars. Experience shows that 10-15 percent of trimming work is performed manually, and at some distances up to 100 percent

Due to the fact that the analogs of the ballast trimmer is not unarmed, the prototype is the ballast trimmer of the Ischenko system / 1 /.

The purpose of the utility model is to facilitate the work of the track fitters, increase their productivity, reduce the cost of the current track maintenance, ensure the quality characteristics of the ballast head, without taking the stage

This goal is achieved by the fact that the ballast cutter is equipped with a working unit with a bin motor or electric motor and a working body such as a chain bar bearing pasioft, made of metal profiles and equipped with wheels, a rail clip, which allows fastening the entire structure to the rail for 3-5 seconds il1y off the rail

Figure 1 shows a ballast trimmer. Frontal projection; in Fig.2 is a side view; in FIG. 3 - top view

The ballast trimmer contains a frame 9 with wheels 10, a working body 1, an engine 12, a gearbox 11, a flexible shaft 13, a feed mechanism for a working body 4 with a feed control drive 7, a rail clip 8 with a feed mechanism 5 and a control handle 3.

The working body 1 is driven into rotation from the engine 12 through a friction clutch, gearbox and flexible shaft 13,

f

when loosening or cutting the soil, the effort of the worker’s hands is applied to the control handle of the drive for feeding the working tool 7. For loosening or cutting under the sole of the rail, the trimmer is fixed to the sole of the rail using the rail clamp 6 with handle 3, the engine is started and the working body 1 is rotated. Further through the feeding mechanisms 4, the working body is brought down: under the sole of the rail

The movement of the cutter in the direction parallel to the rail is carried out by applying the efforts of the hands of the worker to the handle 2 with the pressed rail clip 6.

To skip the train, the handles 2 and 3 are removed as they are equipped with quick-release fasteners. The remaining mechanisms of the trimmer are located outside the size of the rolling stock T and do not interfere with the passage of the train.

Technical result, t, e. the removal of contaminants from under the sole of the rail and the cutting of the upper ballast layer is achieved very quickly due to the fact that the design makes it possible to apply the maximum feed rate of the working body to the rim zone. Processing one sleeper box takes 3-5 seconds. The design capacity of this machine is 150 m / h. This is 7 times higher than the performance when manually performing this operation.
