Abstract
Utility model relates to a central anchoring structure of a bearing cable for suspending an electrified railway contact net, which belongs to the field of special railway devices. A fixing plate of a bearing cable of the device is connected with one end of a plurality of insulating draw rods through pins, and the other end of the insulating draw rods is movably connected with an adjusting fixing plate. The fixing plate of the bearing cable is connected with the other end of an insulator, and the upper end of the insulator is movably connected with an anchor bolt. The adjusting fixing plate forms an L-shaped plate, and a connecting through hole is arranged between the two plates. One end of each of the insulating draw rods is provided with a draw rod adjusting bolt. The device has simple construction and convenient installation, and does not need disconnecting and remaking a joint when the bearing cable is fixed. The electric part does not need adding other attachments, the reliability is high, the request for the pure height in a tunnel is greatly reduced, and the central anchoring structure can be used in the tunnel which can not use the original structure.
Description
Technical field: the utility model is a kind of mid point anchor structure that is used to hang the electrification railway contact net catenary, belongs to railway specialized equipment field.
Background technology: the mid point anchor mode that the electrification railway contact net catenary is installed in the tunnel at present is at the tunnel top inwall anchor arm to be installed, and catenary will cut-off herein, and two string suspended isolators connect at the anchor arm two ends respectively, and open circuited catenary is fixed on the anchor arm.Its main deficiency is very high to tunnel free height requirement, the catenary at anchor arm place disconnects diaphragm, must install additional and electrically connect, at catenary current-carrying section, because the current-carrying capacity deficiency of contact wire also must install transition additional and electrically connect between catenary, increased difficulty of construction, and also can reduce herein contact wire service life, increase operating cost.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned technical deficiency, invent a kind of catenary fixedly the time, need not disconnect but directly pass through, electric part does not need to increase other accessory device reliability height, catenary mid point anchor structure in the electrification railway contact net tunnel that can use in the low tunnel of free height.
Order of the present utility model has like this to be finished: catenary mid point anchor structure in the electrification railway contact net tunnel, it is characterized in that the catenary adapter plate is connected with several insulated tension pole one ends by pin, and the insulated tension pole other end flexibly connects with the adjustment adapter plate; The catenary adapter plate is connected with the insulator other end, and the insulator upper end flexibly connects with crab-bolt; Adjusting adapter plate is the L plate-like shape, has connecting through hole in the two boards; Insulated tension pole one end is equipped with pull bar regulates bolt.
During use, construction location is managed 2-4 screw rod in advance in the tunnel vault, constitute crab-bolt (1), insulator (2) upper end mounting hole is contained on the pre embedded bolt, insulator (2) lower end mounting hole flexibly connects by bolt and catenary adapter plate (3), insulated tension pole (4) has the 2-4 root, and every eradication edge pull bar (4) links by pin and catenary adapter plate (3), connecting rod adjusting bolt (5), adjusts adapter plate (6) and is fixed on the tunnel inwall by cast-in fixing bolt (1).The catenary of electrification railway contact net passes the space in the fixed pulley in the catenary adapter plate (3).The utility model mid point anchor structure can be born the horizontal pull behind the catenary broken string.Insulator (2), insulated tension pole (4) separate charged part and the earth, and bear the pressure that insulated tension pole produces, catenary adapter plate (3) is fixed on catenary on the insulator (2), other end tension force when bearing the catenary broken string simultaneously with insulated tension pole (4), reduce the demand of installation, realize goal of the invention spatial altitude.Where necessary, the utility model mid point anchor structure shouldn't insulator (2), directly thoroughly does away with fixedly catenary adapter plate (3) of edge pull bar (4) with 2-4.
It is simple, easy for installation that the utility model mid point anchor structure has construction, at catenary fixedly the time, do not need to disconnect the joint of reforming, electric part need not increase other accessory device, the reliability height, reducing the requirement to free height in the tunnel greatly, can use in the unsve tunnel of original design, is catenary mid point anchor structure in a kind of novel suitable electrification railway contact net tunnel.
Description of drawings: below in conjunction with accompanying drawing illustrated embodiment structural representation, be described further with regard to the utility model mid point anchor structure, but protection domain is not limited to embodiment.
Fig. 1 is the scheme drawing of catenary mid point anchor structure in the utility model electrification railway contact net tunnel.Wherein insulated tension pole (4) is four.

Fig. 3 is the another kind of structural representation of catenary mid point anchor structure in the utility model electrification railway contact net tunnel.Wherein insulated tension pole (4) is two.
Fig. 4 is a catenary mid point anchor structure birds-eye view in the electrification railway contact net shown in Figure 3 tunnel.
Fig. 5 is the another kind of structural representation of catenary mid point anchor structure in the utility model electrification railway contact net tunnel.Wherein the mid point anchor structure does not have insulator (1).
Fig. 6 is a catenary mid point anchor structure birds-eye view in the electrification railway contact net shown in Figure 5 tunnel.
The specific embodiment: as shown in Figure 1, pre-buried 4 screw rods of the direct hole knockout of vault inwall design attitude are installed crab-bolt in the tunnel, each insulator (2) height just determines according to this electrified railway line contact system voltage, make by producer, insulator (2) is fixed on the tunnel vault by 2 cast-in fixing bolts (1).Catenary adapter plate (3) is bolted to below the insulator (2) by 2.Insulated tension pole (4) links by pin and catenary adapter plate (3) and connecting rod adjusting bolt (6).Pull bar is regulated bolt (5) and is linked by bolt with adjusting adapter plate (6), adjusts adapter plate (6) and is fixed on the wall of hole, tunnel by 2 cast-in fixing bolts.The contact system catenary passes in the space of the fixed pulley centre in the catenary adapter plate (3), need not disconnect the recast joint, but directly connect from catenary adapter plate (3) middle straight.Insulator (2), insulated tension pole (4) separate the charged part of contact system with the earth, electric part need not increase other accessory device; Horizontal pull when insulated tension pole (4) bears the catenary disconnection simultaneously.
1-crab-bolt; 2-insulator; 3-carrier cable fixed head; 4-insulated tension pole; 5-pull bar adjusting bolt; 6-adjustment fixed head.
