Description
Technical Field
The utility model belongs to the technical field of railway line concrete sleeper connecting parts, and particularly relates to a line concrete sleeper integral casting type rail supporting cushion plate assembly.
Background
Because metallurgical enterprise railway operation's vehicle is more and more heavy, the ordinary concrete sleeper that does not set up the backing plate can't satisfy heavy-duty vehicle's operation demand, and railway line concrete sleeper III type bullet strip backing plate is adopted by many metallurgical enterprise railways, has also reduced a lot of maintenance man-hours when guaranteeing driving safety, but because this kind of design itself has certain defect so the popularization scope is limited. To summarize, the design mainly has the following three problems:
1. the design is only suitable for the straight line segment and the curve segment. The weak link of the railway is just curve and switch, that is to say that the railway has trouble and all is in curve and switch region, and the straightway does not basically have, if strengthened the straightway, but the curve that goes wrong most easily can not be strengthened, though can reduce certain maintenance work load after the straight line sets up the backing plate, but originally invert, can't guarantee the railway operation safety.
2. There is a problem that the gauge cannot be adjusted. Because the design utilizes original circuit concrete sleeper, place a slice rubber blotter in the rail bearing groove, then fix the backing plate in the rail bearing groove with two concrete sleeper bolts that the anchor is good, fix the rail with III type bullet strip finally, its two rail gauge of rail after the rail is fixed is exactly 1435mm +6 to-2 within ranges, but the rail rolls the back for a long time through the wheel, because the impact of train wheel pair, the gauge can take place certain change, most commonly the rail inboard can produce fat limit, lead to the gauge reduction of two rails, exceed-2 ranges, but this design is unable to be adjusted, cause and take the measure of changing the rail to solve and can cause the waste, rail polishes can waste a large amount of man-hours, do not solve the dilemma that the gauge exceeds standard again.
3. The same as other circuit concrete sleepers, the concrete sleeper bolt anchoring and concrete sleeper bolt maintenance oiling operation also exist. The line concrete sleeper always adopts the mode of job site anchor, and the operation of bolt anchor just needs to be carried out at first in the operation of changing the concrete sleeper on site, simultaneously in order to prevent the problem of nut and bolt corrosion, carries out bolt oiling operation once at least every year, wastes a large amount of operation man-hours.
