CN2381712Y - Bamboo adhered composite bottom plate for adjusting height of rail - Google Patents

Abstract

The utility model relates to a composite pad plate which is suitable for adjusting the height of rails. The utility model is manufactured by that a rubber or bamboo gluing plane panel is compounded on a rubber plane bottom plate, the middle between the rubber or bamboo gluing plane panel and the rubber plane bottom plate is coated with adhesive, and the rubber or bamboo gluing plane panel and the rubber plane bottom plate are hot pressed. The length of the utility model is from 131 to 190 mm, the width is from 112 to 155 mm, and the thickness is from 4 to 10 mm. The thickness of the bamboo or wooden panel is from 2 to 5 mm. The ratio of the thickness of the rubber bottom plate to the thickness of the bamboo or wooden panel is from 1: 1 to 1.5: 1.

Description

A kind of track is heightened bamboo adhered composite bottom plate

The utility model is that a kind of railroad track maintenance that is applicable to that is formed by rubber and bamboo scutum or wood based panel hot binding is encased inside the bamboo adhered composite bottom plate that the flange of rail is heightened rail level, belongs to railway maintenance operation technique field.

At present, railway track under train gravity percussion, makes track produce the irregularity disease all the year round, causes driving not steady, and train pitches or rolls, and not only the passenger is uncomfortable, and makes vehicle and orbital facilities produce directly harm.When solving the big accent amount irregularity disease of long distance, generally adopt, the method of track lining is justified suitable to circuit, straightening or leveling operation, and when the little daily line maintenance operation of the rail amount of heightening, accepted practice is to be encased inside the level that the flange of rail is adjusted rail with certain thickness bamboo matter or wood based panel, this backing plate loses its elastic deformation very soon through long-time extruding, under the effect of train vibration power and deviate from the flange of rail, what have soaks rotten down rotting at rainwater, lose the effect of bed hedgehopping rail, fragment after rolling then firmly sticks to the flange of rail, make and change very difficulty of backing plate, directly influence line maintenance quality and operating efficiency, under train " heavy duty " " speed-raising " situation, this problem is more outstanding.

The purpose of this utility model is: a kind of good springiness that is integrated by rubber and bamboo matter or wood based panel sinter is provided, is difficult for brokenly, do not heighten bamboo adhered composite bottom plate with flange of rail bonding and the track that is difficult for deviating from the flange of rail.

The purpose of this utility model is achieved in that with extraordinary industrial rubber makes plane bottom plate, a compound in the above flat panel of making by bamboo plywood or wooden plywood, the centre scribbles cementing agent, be composited through the heating pressurization, its length a and following used sleeper width are complementary, and are generally 131 to 190mm, and width b and the top rail flange of rail width of placing are complementary, be generally 112 to 155mm, thickness h is 4 to 10mm.Panel is processed into rectangular flat plate by horizontal, the uniform bamboo matter of endwise tensile strength or wooden plywood's material by design size, and its length and width are consistent with the length and the width of the compound backing plate of this kind, and its thickness C is 2 to 5mm.Base plate is formed by extraordinary industrial rubber compacting, and its length and width are consistent with the length and the width of the compound backing plate of this kind, and its thickness d is 1: 1 to 1.5: 1 with the ratio of the thickness C of panel.

The utility model has the advantages that:

1, owing to the overall structure that adopts rubber to combine with veneer, its adhesion factor strengthens, and is difficult for deviating from the flange of rail under the effect of train impact endurance test shock, and has good water proofing property, and anti-rolling property increases the service life.

2, under long term high temperature, high-pressure work state, be difficult for broken or with flange of rail bonding, change easily, increase work efficiency.

3, model is complete, selects for use conveniently

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a D structure schematic diagram of the present utility model.

Among the figure: 1-rubber bottom plate, 2-bamboo matter gummed panel, 3-cementing agent.

On the rectangular planes rubber bottom plate (1) that extraordinary industrial rubber is made, the plane bamboo matter gummed panel (2) of the same area of compound lastblock and rubber bottom plate (1), cementing agent (3) is coated in the centre, becoming length a through hot pressing is 131 to 190mm, width b is 112 to 155mm, thickness h is that 4 to 10mm whole track is heightened bamboo adhered composite bottom plate, the thickness C of bamboo matter gummed panel (2) is 2 to 5mm, and rubber bottom plate (1) thickness d is 1: 1 to 1.5: 1 with the ratio that bamboo matter is glued together the thickness C of panel (2).

Claims (2)

1, a kind of by rubber bottom plate, scribble the track that cementing agent makes in the middle of bamboo matter or the wooden gummed panel and heighten bamboo adhered composite bottom plate, it is characterized in that: this kind backing plate is by the rubber plane bottom plate, the flat panel that a compound in the above bamboo plywood or wooden plywood make, the centre scribbles cementing agent, and through the plane cuboid that hot pressing forms, length is 131 to 190mm, width is 112 to 155mm, and thickness is 4 to 10mm.

2, bamboo adhered composite bottom plate according to claim 1, it is characterized in that: length and width that the length of bamboo matter or wooden gummed panel and rubber bottom plate and width are equal to this kind backing plate, bamboo matter or wooden gummed plate thickness are 2 to 5mm, and the thickness of rubber bottom plate is 1: 1 to 1.5: 1 with the ratio of the thickness of bamboo matter or wooden gummed panel.
