Abstract
The utility model discloses a method for hanging a fixed contact net by utilizing a beam string structure. Single-lug connectors are respectively mounted at the two ends and middle of the beam string structure, wherein the single-lug connectors at the two ends are respectively connected with inclined cables through pre-stranding strain clamps; the external end of each of the inclined cables is connected with one end of a suspension-type combined insulator; the other end of each suspension-type combined insulator is connected with a first angle end of a triangular connecting plate; a second angle end of each triangular connecting plate is connected with an inclined positioning tube; the suspension-type combined insulator is connected between third angle ends of the two triangular connecting plates; and the single-lug connector in the middle of the beam string structure is connected with an insulator connecting rod through a pipe. According to the method for hanging the fixed contact net by utilizing the beam string structure provided by the utility model, reasonable span and pulling value matching are utilized to realize the hanging and positioning of the contact net; a running function of a vehicle is achieved; the mounting height of a rope above a station is greatly increased; and not only can the requirement for a railway electrifying function be met, but also the social benefit and the economic benefit are excellent.
Description
Technical field
The utility model relates to electrification railway contact net, is specifically related to the fixedly mode of overhead contact line of tension string beam structure (like no platform post awning).
Background technology
Existing tension string beam structure (like no platform post awning) overhead contact line mode down mainly contains two kinds: the one, adopt the headspan suspension scheme, and need headspan wire and upper and lower part positioning rope etc., vertically cross over zone, whole station, location difficulty; Its shortcoming is that lines are more and owing to lead the high 5300mm of surpassing, and bottom positioning rope setting height(from bottom) is lower, makes that the passenger feels to constrain with dangerous on the platform.The 2nd, adopt the davit scheme, its shortcoming is that davit is oversize high headroom building (like no platform post awning) under, and the need reinforcing is processed loaded down with trivial detailsly, and labour intensity is big.
Summary of the invention
The purpose of the utility model provides a kind of stability of structure that both guaranteed, can utilize node and the principle of design of the tension string beam structure that the station public building generally adopts to be applied to solve fixing, the simple fixedly mode of overhead contact line of tension string beam structure that adopts of well coordinating, construct with view of the gentle rope suspension of contact system again dexterously.
For realizing above-mentioned purpose; A kind of tension string beam structure of the utility model design-calculated is overhead contact line fixedly; Its scheme is to be separately installed with the monaural attaching parts at the two ends and the middle part of tension string beam structure, wherein; The monaural attaching parts at two ends is connected with suspension cable through the preformed armor rods strain clamp respectively; The outer end of every skew cables connects suspension type composite insulator one end, and the other end of every suspension type composite insulator connects first jiao of end that triangle is won in succession, and second jiao of end that triangle is won in succession is connected with oblique registration arm; Be connected with the suspension type composite insulator between the triangle end that said two triangles are won in succession, the monaural attaching parts at tension string beam structure middle part is connected with the insulator pitman through a tubing.
In technique scheme, tiltedly on the registration arm suspension pulley is being installed.
In technique scheme, tiltedly on the registration arm registration arm and steady arm device are being installed also.
The utlity model has following advantage:
1, according to horizontal force, the vertical power of hitch point, select the installation site and the angle thereof of suspension cable, both guaranteed stability of structure, again can lifting platform place setting height(from bottom);
2, adopt the preformed armor rods strain clamp to make the junction structure small and exquisite, tight short;
3, the composite insulator pitman realizes that the uplink and downlink contact system is independently-powered, and guarantees that charged spacing looked into 1600mm;
4, the tubing cross section of middle part support is little, can improve stability of structure, can guarantee middle part metal piece reliable ground again.
Description of drawings
Fig. 1 be the utility model tension string beam structure fixedly overhead contact line just locating scheme drawing;
Fig. 2 is an A place structure for amplifying scheme drawing among Fig. 1;
Fig. 3 is a fixedly overhead contact line push off mode scheme drawing of the utility model tension string beam structure;
Among the figure: 1-tension string beam structure (like no platform post awning), 2-monaural attaching parts, the 3-suspension cable, 4-suspension type composite insulator, the 5-triangle is won in succession, the oblique registration arm of 6-, 7-insulator pitman.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:
Like the fixing positive and negative location structure scheme drawing of overhead contact line of Fig. 1, Fig. 2 and tension string beam structure (like no platform post awning) shown in Figure 3; Two ends and middle part at tension string beam structure 1 are separately installed with monaural attaching parts 2; Wherein, The monaural attaching parts 2 at two ends is connected with suspension cable 3 through the preformed armor rods strain clamp respectively, and the outer end of every skew cables 3 connects suspension type composite insulator 4 one ends, and the other end of every suspension type composite insulator 4 connects win in succession first jiao of end of 5 of a triangle; Win in succession second jiao of end of 5 of triangle is connected with oblique registration arm 6; Two triangles are won in succession and are connected with suspension type composite insulator 4 between 5 the triangle end, and the monaural attaching parts 2 at tension string beam structure 1 middle part is connected with insulator pitman 7 through a tubing, tiltedly on the registration arm 6 miscellaneous parts such as suspension pulley, registration arm and steady arm is being installed.
Suspension and location that the utility model is realized contact system through rational span, stagger coupling; Satisfy the locomotive operation function; And the rope setting height(from bottom) of platform top is promoted greatly; Not only satisfy the railway electrification functional requirement, can reduce investment outlay again, have good social benefit and economic benefit.
