Abstract
The utility model relates to a railway traffic management device, particularly a rust prevention device for screw bolts of railway sleepers. The utility model aims to solve the problems of easy rust, increase of repair and servicing periods and waste of labor, time and material resources of the bolts. On the basis of a fixed structure of the existing railway sleeper, an oil storage sleeve pipe is additionally arranged on the external side of a bolt, the existing nut is changed into an oil cup nut, and grease or oil mixture of grease and engine oil is respectively loaded in the oil storage sleeve pipe and an inner cavity of the oil cup nut. Thus, the bolt of the railway sleepers has the advantages of long service life and reduction of repair and servicing periods, and is favorable for the safe running of trains.
Description
The utility model relates to railway traffic management apparatus, especially is a kind of railroad sleeper antirust screw erosion device that is used to guarantee railway traffic safety.
At present, railroad sleeper at the fixing means on the railway is: all section rail is arranged on several sleepers, sleeper mostly is the reinforced concrete goods, the top, two ends of its goods is respectively equipped with the hole of passing for bolt, its bolt bottom is provided with drag hook, drag hook can hook draw ring, can put on metal bar in the draw ring, and draw ring, metal bar are all in the bottom of sleeper.Sleeper top is provided with buckle, and buckle top is provided with the hole that bolt passes, and buckle top is provided with qi shape spring, and bolt passes buckle, and qi shape spring, plain cushion are used nut check.
The effect of railroad sleeper bolt: sleeper bolt is to be fixed on the concrete sleeper two ends, by the fastening rail of buckle, spring and nut, plays rail and the even solid effect together of concrete sleeper.
The easily broken analysis of causes of railroad sleeper bolt and present anti-breaking measure:
The analysis of causes: the sleeper bolt material is a high-quality structural steel, can not prevent the corrosion of oxidation and acid, alkali thing, sleeper bolt in the use is in the natural environment of hot and cold, Exposure to Sunlight, salt, buck on wind, rain, passing car wash away, bolt will soon whole corrosion, and that bolt goes out concrete sleeper 20mm place's corrosion is the most serious, in case the cross section at serious place is little does not reach when requiring and will rupture to tension, shearing resistance in corrosion.
Anti-corrosion measure at present: prevent that at present the sleeper bolt corrosion from being to make miscella through stirring with butter and machine oil, per a year and a half is applied in the whole surface of sleeper bolt once, make sleeper bolt surface form one deck oil film, air-isolation and acid, alkali thing and play the anti-corrosion effect.
The oiling effect:
(1), advantage: the sleeper bolt after the oiling plays the anti-corrosion effect on the great achievement degree very much, has more effectively prolonged the application life of sleeper bolt.
(2), weak point: be exposed under the open-air atmosphere because the sleeper bolt after the oiling is still, the salt, the buck that fall through wind, rain and vehicular traffic wash away, and oiling can not remain on the surface of sleeper bolt for a long time.Year in and year out, in case oil is washed away, the sleeper bolt surface will soon corrosion, and the garden week corrosion that special bolt exposes cement pillow 20mm position is the fastest.
The purpose of this utility model is to overcome the weak point in the above prior art, and provide a kind of can guarantee railroad sleeper bolt long service life, that structure is not numerous and diverse, maintain easily railroad sleeper antirust screw erosion device.
The purpose of this utility model is achieved in that
On the basis of existing railroad sleeper bolt structure, nut is changed into the lubricating cup nut, a corrosion resistant nylon sleeve is set up in bolt outside below the plain cushion of nut bottom, and: between the external surface of sleeper bolt and the lubricating cup nut and coat or be equipped with an amount of miscella (butter, machine oil mix together) between the nylon sleeve.Its concrete condition is: the lubricating cup nut is fused by lubricating cup and plain nut, and wherein lubricating cup is the punching press of 1.5mm steel plate, colds pressing with the processing back nut, spot welding is one, repaiies through mill and makes after spraying paint.The oil storage sleeve pipe is φ 33 * 1.5 nylon tubes.
Using method: floating rust in the clean sleeper bolt of cleaning earlier surface and surface, concrete sleeper bolt place lime-ash, an amount of butter will be added again in sleeve pipe and the lubricating cup, the casing pipe sleeve that will contain butter then is at the sleeper bolt root, adorn buckle, qi shape spring, plain cushion, lubricating cup nut at last successively, and its nut is screwed.
The utility model further specifies middle in conjunction with the accompanying drawings embodiment:
Fig. 1 is the structure chart of railroad sleeper antirust screw erosion device,
Fig. 2 is part, the parts sketch among Fig. 1,
Component and position sequence number thereof in the diagram:
1, railroad sleeper bolt, 2, the lubricating cup nut, 3, plain cushion, 4, qi shape spring, 5, the oil storage sleeve pipe, 6, the railway track flange of rail, 7, rail bed, 8, buckle, 8-1, the hole, 9, the miscella of butter or butter and machine oil, 10, sleeper, 11, drag hook, 12, draw ring, 13, metal bar.
This railroad sleeper antirust screw erosion device mainly is made of the nut of railroad sleeper [10], railroad sleeper bolt [1], drag hook [11], draw ring [12], metal bar [13], buckle [8], qi shape spring [4], plain cushion [3], fastening bolt [1] usefulness.Concrete condition has an oil storage sleeve pipe [5] for the outer setting at the railroad sleeper bolt [1] of plain cushion [3] bottom; Be provided with special bolt [1] corrosion is used a, confession that prevents on railroad sleeper bolt [1] top on plain cushion [3] top and lock the lubricating cup nut [2] of usefulness; Between the outside and sleeve pipe [5] of railroad sleeper bolt [1], and the inner chamber of lubricating cup nut [2] between be respectively equipped with the miscella [9] of butter or butter and machine oil.
Good effect of the present utility model:
(1), the lubricating cup nut substitutes the nut use on the former sleeper bolt.
(2), all scribble the miscella of butter or butter and machine oil in lubricating cup nut and the oil storage sleeve pipe, can in the use Keep sleeper bolt integral body to be closed by oil sealing, and oil can be not excessive. Sleeper spiral shell in the situation that oil remains unchanged Bolt can use for a long time.
(3), can effectively prevent the corrosion of sleeper bolt surface integral, keep sleeper bolt bear external force tension, Shearing resistance is constant, thereby effectively prevents the fracture of sleeper bolt, can greatly prolong the use longevity of sleeper bolt Life guarantees the train safety traffic.
(4), can save a large amount of oilings and recruitment work time cost. The present oilconsumption that is coated with is 40Kg/ Km, the cycle is a year and a half, every kilometer amount of labour used is that 92 work days, (the present actual amount of labour used was greater than 92 Individual), increase corrosion preventing device after, the oiling cycle, comparable present oiling mode prolonged more than 2 times, save Oiling expense and recruitment work time cost approximately will be very considerable.
(5), increase the anti-corrosion device after, make rail track look neat appearance.
