Technical field
The present invention relates to the traffic technique field, relate in particular to a kind of soft location structure of small curve radius of tramway train contact system, and the construction method of the soft location structure of this small curve radius.
Background technology
Along with deepening continuously of urban construction, modern tramway train is with the obvious advantage as the vehicle, has development prospect preferably.Tramway train and arteries of communication are shared right of way will become one of important form of city intensive city space exploitation.
In the road overhead, its pillar will inevitably exert an influence to arteries of communication with the tramway train catenary erection.At tramway train turning crossing, its turn radius is little, hitch point is many, pillar is intensive, and is particularly thorny with arteries of communication.Satisfying under the condition of normal arteries of communication, can not set up pillar in road; And satisfying under the contact system normal operating conditions, needing to set up pillar in road or adopt complex structure and the large headspan suspension of quantities, the former has a strong impact on arteries of communication, and the latter makes a very bad impression to road and urban look.
As shown in Figure 1 and Figure 2, be headspan suspension in tramway train contact system sharp radius curve place contact system form commonly used at present, at intersection, many group columns 1 are set, and successively by bearing 2, steel strand 5, two B drag-line 51, drag-line 52 etc., form fixed sturcture, be used for hanging the overhead contact line 9 of tramway train.This technical scheme complex structure, thereby material and equipment consumption are large, reliability is lower.
Those skilled in the art are devoted to develop a kind of urban tram field of being applied in, and arteries of communication can be satisfied and the contact system service conditions can be satisfied again, and sharp radius curve place's contact system structure and construction method thereof simple in structure, that fiduciary level is high.
Summary of the invention
Because the defects of prior art, technical matters to be solved by this invention is to provide a kind of soft location structure of small curve radius of simple in structure, tramway train contact system that reliability is high.
For achieving the above object, the invention provides a kind of soft location structure of small curve radius of tramway train contact system, comprise pillar; Be provided with bearing on described pillar, insulator is connected with bearing by adjusting bolt, and described insulator is connected with contact wire by steel strand, steady ring, registration arm, wire clamp successively.
Preferably, described pillar is the welding steel column.
Preferably, described pillar apart from road axis greater than 20 meters.
The present invention also provides a kind of construction method of the soft location structure of small curve radius of tramway train contact system, and step 1 arranges pillar at road channelization island or road both sides; Step 2, assigned address erection support on described pillar; Step 3 is connected contact wire by registration device with bearing.
Preferably, described pillar is built up in the curve outside of described contact wire.
Preferably, the radius of described curve is less than 25 meters.
Preferably, the distance of described pillar and described contact wire is greater than 20 meters.
Preferably, described registration device comprises wire clamp, steady ring, registration arm, steel strand, insulator, adjusting bolt.
Preferably, the axis of described registration device is vertical with described contact wire.
The invention has the beneficial effects as follows:
Of the present invention by said method and structure design, solved the contradiction of urban tram catenary mast and arteries of communication, satisfy again the urban look requirement simultaneously, improved catenary property.Due to simple and reliable for structure, also make construction and maintenance cost reduce, have wide application.
Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand fully purpose of the present invention, feature and effect.

The specific embodiment
As shown in Figure 3, Figure 4, the soft location structure of a kind of small curve radius of tramway train contact system comprises the pillar 1 of contact system.Pillar 1 is built in road channelization island or the road both sides in the contact wire 9 curves outsides, makes pillar 1 not affect the surface road traffic.Pillar 1 is the welding steel column, in the present embodiment, apart from road axis greater than 20 meters.
Be provided with bearing 2 on pillar 1, bearing 2 is fixed on the desired location of pillar 1, determines angle, length and the position of bearing 2 on pillar 1 of steel strand 51 by Mechanics Calculation, according to the position erection support 2 that calculates.
One side of insulator 4 is connected with bearing 2 by adjusting bolt 3.The opposite side of insulator 4 is connected with contact wire 9 by steel strand 51, steady ring 6, registration arm 7, wire clamp 8 successively.
Said structure of the present invention is particularly useful for small curve radius, and (radius of curve can less than 25 meters) can satisfy the requirement of tramway train normal operation at the small curve radius place; Reduce curve hitch point place due to contact wire 9 tension variation that the temperature traverse effect causes, can increase the anchor segment length.
The present invention also provides a kind of construction method of the soft location structure of small curve radius of tramway train contact system:
Step 1 arranges pillar 1 at road channelization island or road both sides.Pillar 1 is built up in the curve outside of contact wire 9, and the radius of curve is less than 25 meters, and simultaneously, the distance of pillar 1 and contact wire 9 is greater than 20 meters.
Step 2, assigned address erection support 2 on pillar 1.According to the length intercepting steel strand 51 that calculate, and its left end is connected with steady ring 6, registration arm 7, wire clamp 8, contact wire 9 successively; Its right-hand member is connected with insulator 4, adjusting bolt 3 successively.
Step 3 is connected contact wire 9 by registration device with bearing 2.
