Description

Technical Field

[0001] The utility model relates to the technical field of ballast backfilling, in particular to a ballast backfilling device with multi-stage control of ballast flow. Background Art

[0002] The ballasted track of railways and urban rail transit consists of rails, fasteners, sleepers, roadbed, and roadbed from top to bottom. It is the main track structure form of current conventional railways and heavy-haul railways, and also has a certain proportion in special sections of high-speed railways and urban rail transit.

[0003] The roadbed is composed of ballast, which is a granular structure. After forming the roadbed, its functions are as follows:

[0004] 1. The train load and track load are diffused through the ballast and then transferred to the roadbed, thereby reducing the load pressure on the roadbed surface and protecting the top surface of the roadbed;

[0005] 2. Provide longitudinal and transverse resistance to the track, and play a role in maintaining the geometric stability of the track;

[0006] 3. The elasticity and damping of the track bed can absorb the impact vibration between the wheel and rail;

[0007] Fourth, the loose nature of ballast makes it easy to break and deform, but also easy to work with, and convenient to repair and adjust;

[0008] After long-term use, the railway track becomes dirty, the ballast is broken, and the track loses its elasticity and drainage performance, which in turn causes the entire track to become "hardened", which is not conducive to railway transportation. Therefore, when the degree of track dirtiness exceeds 25% by weight, it must be screened to separate the dirt from the clean ballast. The ballast that meets the specifications is then returned to the track along the return mechanism.

[0009] The existing screening machines are all single-stage ballast flow control mechanisms, which can only control the total flow of backfill ballast, and cannot simultaneously control the ballast backfill flow of the left and right strands of the line and the inner and outer sides of a single strand. The adjustment capacity is limited and there is a situation where the adjustment is not timely, and accurate backfill control cannot be achieved. In addition, the flow direction of the backfill ballast is difficult to take into account the super-high sections of the curve at the same time, and the adaptability of the line operation is not strong. At the same time, the existing backfill device does not have a ballast storage function. In the event of an emergency stop during the operation of the screening vehicle, it is difficult to stop the backfill ballast in time, resulting in ballast accumulation on the line, affecting driving safety.
