The utility model is characterized in that it is composed of a pedestal, a rod insulator, a positioning tube, a height limiter, a positioning ring, a positioning tube arresting device, adjustable hangers and a connected bolt, wherein, the pedestal is composed of two long angle-bars, four double-ears and a short adjusting bolt; the pedestal is a hinge structure, and one end of two adjustable hangers is fixed on the water level wrist-arm by the positioning tube arresting device, the other of which is connected with the carrier cable; the positioning device adopts the height limiter whose one end is fixed on the contact wires location and other end is connected with the positioning ring by the hook ring. The end of the positioning device is provided with adjustable screws for adjusting the contact wires lifting amount, and the positioning ring is fixed on the water level wrist-arm by four bolts. The single line tunnel integral positioning device is provided with height limiting function, is able to improve bow net relationship and enhances engines operation speed.

Description

The whole registration device in single line tunnel

Affiliated technical field:

The utility model relates to a kind of gold utensil that uses in the electrified railway tunnels contact system, and it can be used for contact wire location in the single line tunnel overhead contact system, is the whole registration device in a kind of single line tunnel.

Background technology:

Well whether contacting between contact wire and the motorcycle pantograph in the single line tunnel overhead contact system is a key factor of decision motor supply shop vehicle speed; And contact wire location does not have and anti-ly raises function in original tunnel, and contact wire contact effect with pantograph bad, cause that the locomotive supply regular power becomes the time break when continuing, make electric locomotive get stream condition variation, influenced road speed.Under the overall background of present train speed raising, be badly in need of a kind of anti-contact wire registration device of raising performance that has, to improve pantograph contact line relation, make locomotive get the stream condition and improve, running velocity is accelerated.

Summary of the invention:

The purpose of this utility model just provides the whole registration device in a kind of single line tunnel, and this device has to be prevented raising function, can improve pantograph contact line relation, and locomotive running speed is improved.

The purpose of this utility model is to realize like this, design the whole registration device in a kind of single line tunnel, it is characterized in that: it by base, strut insulator, registration arm, anti-ly raise steady arm, steady ring, registration arm clamp, adjustable integral hanger and tie bolt and form; Base is by two angle steel that length is the same, and the adjustable bolt of four ears and a weak point connects and composes; Base is an articulated structure, and two adjustable integral hanger one ends are fixed on the horizontal bracket by the registration arm clamp, and the other end links to each other with catenary; Steady arm adopts to be prevented raising steady arm, and an end is the contact wire position fixedly, and the other end is connected by shackle with steady ring, and the steady arm end has adjustable jackscrew, and steady ring is bolted on the horizontal bracket by four.

Four ears are arranged on the described base, and two ears are welded on the base angle steel, and two ears weld togethers are connected with the ears that are welded in base angle steel top by bolt in addition.

Described two adjustable integral hangers that are suspended on the catenary constitute " V " word shape.

It is described that anti-to raise steady arm be the aluminum alloy steady arm,

It is described that anti-to raise steady arm be the steel steady arm.

The utility model has the advantages that: the base of the whole registration device in single line tunnel is the hinge junction structure, is applicable to the tunnel arm of different degree of dip, and it all can make with strut insulator bonded assembly ears and be the level of state.Horizontal bracket is suspended on the catenary by V-type, has alleviated dead weight.Steady arm adopts to be prevented raising steady arm, has improved pantograph contact line relation, and locomotive speed is improved.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Description of drawings:

Fig. 1 is the utility model example structure scheme drawing;

Among the figure, 1, base; 2, angle steel; 3, following ears; 4, adjustable bolt; 5, go up ears; 6, vertical ears 7, flat ears 8, strut insulator 9, horizontal bracket; 10, registration arm clamp; 11, adjustable integral hanger 12, contact wire 13, steady arm; 14, steady ring; 15, pipe cap; 16, steady ring anchor ear 17, catenary.

The specific embodiment: embodiment as shown in Figure 1, its base 1 by the same angle steel 2 of two length, down ears 3, go up ears 5, flat ears 7, vertically ears 6, adjustable bolts 4 are formed; Two angle steel 2 are fixed on the tunnel wall by expansion bolt or chemical bolt; Following ears 3, last ears 5 are welded between two angle steel 2; Flat ears 7, vertical ears 6 weld togethers; Following ears 3 are connected by adjustable bolt 4 with vertical ears 6; Adjustable bolt 4 works to support flat ears 7 and scalable length; Flat ears 7 one ends are connected with last ears 5 by bolt, and the other end is by bolted connection strut insulator 8; Horizontal bracket 9 one ends insert within the strut insulator 8 and by bolt, end has pipe cap 15; Two registration arm clamps 10 are fixed on the horizontal bracket, and certain distance is left in the centre; Two adjustable integral hanger 11 1 ends are connected with registration arm clamp 10, and the other end is suspended on the catenary 17; Steady ring 14 and steady ring anchor ear 16 are by being bolted on the horizontal bracket 9; Steady arm 13 is that aluminum alloy is prevented raising steady arm, and its end is contact wire 12 positions fixedly, and the other end is connected with steady ring 14 by shackle, and steady arm 13 ends have adjustable jackscrew, are used to adjust the contact wire amount of raising.
