Problems solved by technology

Although large and medium-sized sieve cleaners have advantages for long-distance overhaul and sieve cleaning operations, they also have limitations. For example, their operating width is at least 4m, which greatly limits the operating environment and puts forward high requirements for the operating space of the operating road section. ;Due to the long size, it is easy to run off, so it is necessary to check the operation of each conveyor belt frequently and adjust it in time; it is necessary to check the fastening of each supporting part frequently to avoid accidents such as breakage; it is necessary to clean the screen every 30 minutes It is necessary to inject lubricating grease to the corner rollers of the guide groove; the volume is large, there are many parts, it is difficult to troubleshoot, it is not easy to repair, the cost of mechanical maintenance and the probability of repair are high, and it is a waste of time. It is not suitable for short-distance and limited-time ballast cleaning operations.
For road sections with narrow working space, short distance, and limited cleaning requirements of the railway department, such as cleaning and backfilling of ballast on one-sided mountain or single-fork road sections, the existing large and medium-sized cleaning machines cannot meet the requirements. Ballast cleaning work is still dominated by manpower and manual tools
Especially in areas with serious compaction, ballast cleaning operation is labor-intensive and labor-intensive

Embodiment 1

[0040] When the present invention is used for ballast cleaning work on main line railway sections without turnouts, after the small-scale railway ballast cleaner described in the present invention is transported to the work site, the ballast cleaning mechanism 4 and the track in the initial installation area of ​​the ditching plow group 2 are firstly removed. The ballast is cleaned up, and then the furrowing plow group 2 is installed on the car body 1. As the car body 1 advances on the rail 6, the furrowing plow group 2 opens a groove 23 on one side of the sleeper 5 where the ballast conveying mechanism 3 can be installed. Return the vehicle body 1 to the initial area, install the ballast conveying mechanism 3, the ballast cleaning mechanism 4 and the ballast cleaning mechanism support 7 according to the predetermined position and assembly method, and then start the ballast cleaning operation. During the operation, as the ditching plow group 2 clears the road, the ballast clea...

Embodiment 2

[0043] For the main line railway with complex working environment, the obstacles on the side of the railway track are sometimes distributed on the left side and sometimes on the right side, which hinders the continuous operation of the small railway ballast cleaner. can be prepared as figure 2 and Figure 7 One set of furrowing plow groups 2 are shown. According to the working environment, it is determined that the furrowing plow group 2 and the ballast conveying mechanism 3 are installed on the left or right side of the car body 1. After the installation position is determined, at the designated initial position Clear out a certain installation space and assemble the furrowing plow group 2, then determine the ballast discharge direction of the ballast conveying mechanism 3, correctly install the lateral slide plate 323 and the adjustable support rod 36, and complete the assembly of each module of the small railway ballast cleaner Afterwards, carry out ballast cleaning work ...

Embodiment 3

[0046] The single turnout area is composed of two tracks (such as A track and B track). Two small-scale railway ballast cleaners described in the present invention are used to perform ballast cleaning operations on the single turnout area. as attached Figure 8 As shown, S1 and S2 are used in pairs as attached Figure 1-3 For the two right-side ballast cleaning small-scale railway ballast cleaners shown, the preparation area I and the preparation area II are the operation start areas of S1 and S2 respectively. Firstly, S1 and S2 are transported to respective preparatory areas respectively, and the installation spaces of ballast cleaning mechanism 4 and furrowing plow group 2 on S1 and S2 are cleared in preparatory area I and preparatory area II. Then the furrowing plow group 2 is installed on the vehicle body 1 . As the vehicle body 1 travels on the rail 6, the furrowing plow group 2 drives the furrow 23. Return the car body 1 to the initial area, install the ballast conve...

Abstract

The invention relates to a small railway ballast clearing machine suitable for main track bed and single turnout area ballast clearing operation. The railway ballast clearing machine is composed of avehicle body (1), a gutter plough group (2), a raked ballast conveying mechanism (3) and a ballast clearing mechanism (4). The small railway ballast clearing machine can be flexibly assembled according to mechanisms and modules, thereby being convenient to mount and demount, easy to transport and simple and convenient for maintenance. Multiple small railway ballast clearing machines can be used for cooperation, so that working efficiency can be further improved, mounting and demounting time can be saved, and needs of local small-range construction can be met better.

Description

technical field [0001] The invention relates to a small-sized railway ballast cleaning machine suitable for ballast cleaning operations in track beds and single turnout areas. Background technique [0002] The ballast bed is a ballast (stone ballast) cushion layer laid on the roadbed surface. Its main function is to support the sleeper, maintain the position of the sleeper, prevent the sleeper from moving longitudinally or laterally, transmit the pressure on the upper part of the sleeper to the roadbed evenly, and drain the ground rainwater. , so that the track has enough elasticity to ease the impact of rolling stock on the rail. The soil brought into the ballast bed by wind and water, or the ballast powder often fills the gaps in the ballast bed, making the ballast bed an impermeable layer and poor drainage, which eventually leads to hardening of the ballast bed, decreased elasticity, and poor shock absorption effect. Thereby affecting driving safety. As a result, railro...
