Abstract
The utility model relates to a simple contact elastic hanging unit which is used for hangings in low clearance tunnels of electric railway section. The simple contact elastic hanging unit adopts a movable wheel which is provided with notches around as hangers, and a shaft line of the movable wheel is perpendicular to a plane which is formed by a sling and a contact line. The utility model with the advantages of simple structure, flexible operation, small frictional resistance, small occupation of headroom, improved hanging elastic, good conditions of fetching streams of electric locomotives can meet the requirement of air-insulation clearance of 300 mm.
Description
The utility model belongs to a kind of chevron pointing contact suspension device, is used for the suspension gear in the building (for example overline bridge, overpass bridge etc.), particularly is used in the simple contact suspension device of elasticity in the railway electrification section low headroom tunnel.
The simple contact suspension device of low clearance adopts the sliding tube mode both at home and abroad at present.For example " threefold ring+sliding tube " adopted in section electrified railway in treasured-sky; Phoenix-wide section farming family ditch adopts " removing metal plate+sliding tube " in the tunnel; Stone-Tai line adopts " trapezoidal metal plate+sliding tube ".Because parts are cliding friction modes, the friction drag of parts is big.Whole in addition parts weight is big, influences the compensation of contact wire tension force.Therefore, all exist and hang poor flexibility, the contact wire abrasion are serious, and shortcomings such as stream condition difference are got in electric locomotive.The tramway type suspension equip ment device that has (as precious day section) still can not satisfy the requirement of air insulation clearance (for example 300mm).
Existing foreign technology, a kind of " the chevron pointing stringing spring loaded hanger device " narrated as Japanese documentation (clear 59-5455) be by triangle hang metal plate, draw metal plate, several parts such as armature of spring strut, pull bar, clamping pull bar link and work.This spring loaded hanger device complex structure, it is bigger to take headroom, and difficulty is installed, easy-maintaining not, cost height.
In view of the problem that above-mentioned prior art exists, task of the present utility model is that design is a kind of new simple in structure, can satisfy that to take clear headroom little, and the friction drag of parts is little, and raising suspension elasticity is improved the needs that the stream condition is got in electric locomotive.
Its solution is: the suspension element of apparatus of the present invention is to adopt the reeded fixed pulley of peripheral band, imbedding rod member by one is fixed on fixed pulley on the building, hoist cable is connected with the insulator of both sides respectively by fixed pulley, is connected with contact wire with the hoist cable wire clamp in the end of two insulators.
Now in conjunction with the accompanying drawings embodiments of the invention are described in detail as follows:
Accompanying drawing 1 is the simple contact suspension schematic representation of apparatus of a kind of elasticity.
Among the figure: 1 is that hoist cable wire clamp 4 is fixed pulley
2 is that insulator 5 is for imbedding rod member
3 is that hoist cable 6 is contact wire
The member that main points of the present utility model are to hang employing is to consist of by imbedding the reeded fixed pulley of peripheral band (4) that rod member (5) is fixed on the building by one. This axis of taking turns is perpendicular to hoist cable (3) and contact wire (6) formed plane. Two side slings (3) of fixed pulley (4) are distinguished connecting insulator (2) and are fixedly connected with contact wire (6) by suspending cable clamp (1) in its end.
Dotted portion has represented clear in the utility model working condition accompanying drawing 1.
The utility model is compared with prior art simple in structure, and is easy for installation, uses flexibly, hangs good springiness, and hard spot is few, and frictional resistance is little, is subjected to the stream condition good. It is little to take head room, satisfies the requirement of air insulation clearance.
Claims (3)
1, a kind of simple contact suspension device of being made up of suspension element, hoist cable, insulator, hoist cable wire clamp of elasticity, the suspension element that it is characterized in that this device are to imbed the reeded fixed pulley of peripheral band (4) that rod member (5) is fixed on the building by one to constitute.
2, suspension gear according to claim 1 is characterized in that fixed pulley (4)
Its axis normal is in hoist cable (3) and contact wire (6) formed plane.
3, suspension gear according to claim 1, two side slings (3) that it is characterized in that fixed pulley (4) are connected with insulator (2) respectively and are fixedly connected by hoist cable wire clamp (1) and contact wire (6) in its end.
