Description

Sealed type combined unit equipment for control desk of railway station

The utility model relates to the improvement of the station control desk in the railway station letter collection closed system, particularly relates to the closed type card assembled unit device of railway station control desk.

The railway station control desk is to improve driving efficient, the requisite basic equipment of guarantee driving safety, but now the station use or producing mostly be five, the approved product in the sixties, to be example at the TD3 type unit control table of producing and use at present in the prior art, following shortcoming is arranged:

1, expenditure of energy is big, and the luminescent device of existing unit adopts filament bulb, and electric current big (the about 200MA electric current of each bulb), efficient are low, power consumption height and life-span weak point.

2, high material consumption, big (43mm * the 43mm * 60mm) of volume, except the short covering unit, the simplest cell type also will be made up of glass seat, glass bar, heat radiation joint (aluminium), contact joint (copper, silver), dottle pin (rubber), cylinder manifold (copper), optically focused joint (bakelite) or the like 21 parts, the most complicated then will form up to 67 parts, consume metal and non-metallic materials such as a large amount of copper, aluminium, silver, and when assembling is time-consuming, difficulty is big.

3, button is clumsy, operation inconvenience, and maintenance load is big.

4, unit blowing-by, the easy dust stratification of unit block, corrosion, maintenance load is big, the fault rate height.

5, light belt is discontinuous, even now the light belt of existing some control desk adopts the LED plane luminescence device, but the straight thigh of track switch still is two independently display units with curved strand, therefore still has interrupted section when the side line route light shows.

Because the problem that existing unit block exists, railway interests has in use felt very big inconvenience, and for development and on-the-spot the pressing for that adapts to modern science and technology, we develop this new closed type does not have maintenance light belt cell arrangement.

Main purpose of the present utility model is, overcome the drawback of prior art, and provide a kind of closed type card assembled unit device of railway station control desk, make it all adopt the mould mass production, can simplify production program, have simple in structure, easy, easy to maintenance, the energy savings of combination, economical with materials, and have the effect of not having interrupted section when light belt shows.

The purpose of this utility model is realized by following technical scheme:

A kind of closed type card assembled unit device of railway station control desk, the control desk card is made up of with the elementary cell of various operations and demonstration grid-like dish seat, it is characterized in that:

The dovetail of the A type unit of card and the dovetail furrow of Type B unit are chimeric mutually, to constitute grid-like dish seat, the big I of dish seat is made up of any a plurality of unit, each elementary cell is by cell cube, back shroud assembly, wire size capping, and constitute by light belt and printed circuit-board assembly, and directly be inserted in dish seat by various dissimilar elementary cells, constitute the card of station control desk.

The purpose of this utility model can also further be realized by following technical scheme.

The closed type card assembled unit device of aforesaid railway station control desk is characterized in that: the front that described A type unit, Type B unit, elementary cell show is a square or rectangular.

The closed type card assembled unit device of aforesaid railway station control desk, it is characterized in that: described light belt type shape is respectively: A, left track switch light belt, B, right track switch light belt, C, triangle branch-cut bridge track switch light belt, D, V-arrangement branch-cut bridge track switch light belt, E, trapezoidal light belt, F, half direct light band, G, direct light band, various track switch light belts are a complete integral body, do not occur interrupted section when arbitrary route shows.

The closed type card assembled unit device of aforesaid railway station control desk is characterized in that: the position on described wire size envelope covering position and the back shroud assembly is for corresponding one by one.

The utility model compared with prior art has following advantage:

1, whole molds, production is simple, batch is big, cost is low.

2, combination is simple, and new unit is made up of five kinds of fire-retardant ABS engineering plastics bare bones, seven kinds of LED light emitting diode light tape cells and resistance, button, and 58 kinds of elementary cells of one-tenth capable of being combined satisfy the needs of field, station, any big or small station of railway fully.

3, owing to adopt overall plastic of flame retardant type, insulating power and fire resistance are good.

4, adopt LED lumination of light emitting diode device, then consume energy low (every Guan Ruiyue 5-20MA), the life-span long (about 10 ⁷Hour) various track switches band is an integral body, do not have interrupted section when the track switch light belt is shown.

5, adopt nothing maintenance soft-touch type micro-switch, life-span long (5 * 10 ⁶Inferior) do not have and keep in repair.

6, consider that from block construction the front is that display surface is a square or rectangular, volume is little, hermetically sealed, and it is simple to change the unit, the anxiety of no dust and corrosion infringement.

7, owing to adopted the wire size capping, bonding wire, maintenance all can really can be accurate, also make distribution salubrious, attractive in appearance.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
