Problems solved by technology
[0006] The object of the present invention is to provide a locomotive sand spreading control system and control method for the problem that sanding has a poor effect on improving the adhesion between wheel and rail when there are sundries on the rail surface or when the rail surface is wet. Or when the rail surface is wet, it can improve the effect of sanding on the adhesion performance between the wheel and rail

Embodiment Construction
[0034] Taking the sand control of a six-axle locomotive as an example, such as figure 2 As shown, the locomotive sanding control system includes a total air source 22, a set of end forward sand spreaders 5, 6 (installed at the wheel set of the first shaft), a set of end backward sand spreaders 11, 12 (installed at the wheel set of the 6th axle), a set of non-end forward sand spreaders 7, 8 (installed at the wheel set of the 4th axle), a set of non-end backward sand spreaders 9, 10 (Installed at the wheel set of the third shaft), end forward sand spreaders 5, 6, end backward sand spreaders 11, 12, non-end forward sand spreaders 7, 8, non-end forward sand spreaders Back sand spreader 9,10 all can be communicated with total wind source 22; Wherein:
[0035] The end forward sand spreaders 5, 6 and the non-end forward sand spreaders 7, 8 are used to communicate with the main wind source 22 and spread sand when the locomotive has a demand for sand forward.
[0036] The end sand s...

The invention discloses a locomotive sand spreading control system and a control method, wherein the sand spreading control system includes a total air source, a set of end forward sand spreaders, a set of end backward sand spreaders, at least one set of non-end sand spreaders Part forward sander, at least one set of non-end rearward sander, end forward sander, end rearward sander, non-end forward sander, non-end rearward The sanders can be connected with the total wind source; also include the first blowing branch connected in parallel with each non-end forward sanding device, and the second blowing branch connected in parallel with each non-end backward sanding device; the first The blowing branch is used to communicate with the main air source and blow on the rail surface when the locomotive needs to sprinkle sand backwards; the second blowing branch is used to communicate with the main air source and blow to the rail surface when the locomotive needs to sprinkle sand forward Hair. The invention can improve the effect of sand spreading on the wheel-rail adhesion performance.
Description
technical field [0001] The invention belongs to the field of rail traffic braking control, and in particular relates to a locomotive sand spreading control system and a control method. Background technique [0002] In the field of rail transportation technology, the adhesion between the wheel and rail of a locomotive plays a crucial role in its operation. Depending on the operating environment, oil stains, water stains, dust and other sundries tend to accumulate between the wheels and rails, resulting in a decrease in the adhesion between the wheels and rails, which can easily cause the locomotive to idling and slip. [0003] At present, the method commonly used by locomotives to improve the adhesion between wheel and rail is to sprinkle sand. The sand-sprinkling technology is to spray sand with a certain size on the rail surface, and the sand-sprinkling direction is opposite to the forward direction of the locomotive. [0004] Take the six-axle locomotive as an example, s...
