Abstract

The utility model relates to a part-rolling sliding soleplate, which is composed of a rolling part (21) and a sliding part (15), wherein the rolling part (21) is composed of a roller (17), a detachable axle bed (3) and a fixing axle bed (18), and the sliding part (15) is composed of a sliding panel (19) and a support (20). When the railroad switches, the movement of tongue rails is performed in the mixed friction with a minimal friction coefficient and the mixed friction combines the rolling friction and the sliding friction. The utility model has the advantages that the sensitivity and the service life of the equipment are improved, the convenient maintenance is provided, a large amount of the power supply and the lubrication oil are economized and the utility model has an objective long safe economic benefit.

Description

The slide plate that can partly roll

The slide plate that a kind of railway switch of technical field is used, particularly a kind of slide plate that can partly roll.

The background technology railway switch is realized turn-out track for mobile tongue swimmingly, for these years, all is to use flat slide plate, by apply lubrication oil regularly, comes the holding plate face smooth.But this method is the high sliding friction of a kind of friction factor after all, and will wastes a large amount of lubrication oil; The employing of heavy rail requires goat that bigger power performance is arranged, if also adopt traditional slide plate, not only takes electricity, also easily motor is produced infringement.

The summary of the invention the purpose of this utility model will provide a kind of process that moves at tongue exactly, before no arrival is not pressed close to stock rail, moves to stock rail in the mode of rolling friction; Also in the mode of rolling friction to the slide plate that can partly roll that breaks away from the motion of stock rail direction.

The utility model is achieved like this: the slide plate that can partly roll is made up of roll part and slipper.These two parts get together, and are fixed on the base plate that is fixed on the sleeper.Like this, will make tongue after the part of rolling rolls across trippingly, just slide into through very short sliding distance again and lean against on the stock rail.Slipper is made of slidable panels and support.The part of rolling is made of the removable axle bed of roller, backing roll, fixed axle bed.Have several sleeve blocks the contour number such as equidistant of the upright medial surface of removable axle bed and fixed axle bed, vertically have oily wire casing above; The oil wire casing is drilled with oil seepage hole downwards over against the sleeve block place; Oil has in the wire casing inhales the oily line that oozes lubrication oil, makes of cotton thread; There is a slice to be pressed in the oil-hole cover that blocks dust on the oily line under the oil filler point on the oily wire casing cover plate; Fixed axle bed solid welding is on base plate; Removable axle bed by with the buck plate of its one, be fixed on the base plate with the assembling screw; Axle sleeve is fitted in the sleeve block, the oil seepage hole of the axle sleeve oil seepage hole on it on the oily wire casing; The roll shaft of roller inserts in the axle sleeve; During installation, roller and slidable panels are kept at grade.

Because the lubricated oil of oily line fully soaks into, lubrication oil oozes between axle sleeve and axle by oil seepage hole and infiltrates, and the axle of roller can be rotated in axle sleeve neatly.Removable axle bed is for more roll change and axle sleeve provide convenience.When tongue was on roller, very little action current will make the frog motion.The slide plate complex structure that the utility model structure is more traditional is a little, but the safe and reliable flexibility of action is greatly improved, and has reduced the starting current and the action current of goat widely, and not only economize on electricity has also prolonged life-span of motor; Simultaneously, the lubricating system that does not promptly fully have waste again also can be saved a large amount of lubrication oil; Structure makes daily maintenance more convenient cleverly.Therefore, the utlity model has long-range security reliability and economic benefit.

It is front views that description of drawings the utility model has three accompanying drawing: Fig. 1, Fig. 2 be the A-A of Fig. 1 to sectional view, Fig. 3 is that the B-B of Fig. 2 is to sectional view.

Embodiment describes the utility model below in conjunction with accompanying drawing: the utility model is made up of roll part (21) and slipper (15).These two parts get together, and being fixed on one has on the base plate that can pass the screw hole (2) that is fixed on the screw rod on the sleeper; Slipper (15) is by slidable panels (19) and support (20) formation; The part (21) of rolling (scope that encloses with chain-dotted line) is made of roller (17), removable axle bed (3), fixed axle bed (18); Have several axle bed covers (12) the contour number such as equidistant of the upright medial surface (22) of removable axle bed (3) and fixed axle bed (18), vertically have oily wire casing (10) above; Oil wire casing (10) locates to be drilled with oil seepage hole (14) downwards over against sleeve block (12); Fill in oil wire casing (10) make of cotton thread, in order to receive the oily line (7) of lubrication oil; Pressing a slice to block the oil-hole cover of dust (10) on the oily line (7) that oil filler point (9) on oily wire casing cover plate (5) is located; Fixed axle bed (3) solid welding is on base plate (1); Removable axle bed (3) by with the buck plate (4) of its one, be fixed on the base plate (1) with assembling screw (6); Axle sleeve (13) is fitted in the sleeve block (12), and the axle sleeve oil seepage hole (14) on it is over against the oil seepage hole (11) of oily wire casing (10); The roll shaft (16) of roller (17) inserts in the axle sleeve (12); During installation, roller (17) and slidable panels (19) are kept at grade.Tumbling-type friction and sufficient lubricating greatly reduce the starting current and the action current of goat, the safe and reliable sensitivity and the life-span of having improved equipment; Convenient, flexible compact structure is that maintaining is provided convenience, and can save a large amount of lubrication oil.So the utility model has considerable long-range safety economy benefit.
