Abstract

The utility model relates to a double handle saddle belonging to the fittings used for suspending the wires in the electrified railway contact system. The utility model is characterized in that the double handle saddle main body is a symmetrical body; the left and the right ends of the main body are provided with curved double hook. The left and right inside of the double hook are provided with two opposite elongated slots by a center line. The elongated slots have a distance from the bottom of the board. The top and the bottom of the elongated slots are respectively provided with a hole. The top of the double handle saddle main body is provided with an upper beam of the double handle saddle. The bottom of the double handle saddle main body is provided with a lower beam of the double handle saddle. The upper beam is in the double-layer structure and is provided with a hole along the center line. The hole penetrates through the left and right layers of the upper beam. The hole diameter of the upper beam along the center line is phi 18. The upper beam is 40mm wide and 30mm thick. The distance between the left and right layers of the upper beam is 18mm. The double handle saddle has high intensity, and can adapt to the influence of the increased tension of the back wire after the locomotive speeding up.

Description

Double handle saddle

Affiliated technical field:

The utility model relates to the gold utensil that uses in a kind of railway contact line, is applicable to the Double handle saddle that hangs clue in the electrifing railway contacting net system.

Background technology:

Whether the Double handle saddle that hangs clue in the electrification railway contact net is solid and reliable, directly affect the safe in operation of electrified railway, adopt foundry technique at existing Double handle saddle owing to it, there are various foundry defects unavoidably in the Double handle saddle body, safe in utilization and life-span is affected, particularly along with the speed-raising of railway line, originally be subjected to the increase of thread tension force by the Double handle saddle body of foundry technique processing, problem often takes place in its intensity.

Summary of the invention:

The purpose of this utility model provides a kind of Double handle saddle, and its intensity height can satisfy the influence that thread tension force increases behind the speed increase in vehicle.

The purpose of this utility model is achieved in that a kind of Double handle saddle, it is characterized in that: the Double handle saddle body is a symmetric body, and there is crooked double hook at left and right two ends; About double hook inboard and with line of centers to having elongated slot, elongated slot has distance at the bottom of plate, elongated slot respectively has a hole up and down; Being the upper beam of Double handle saddle above the Double handle saddle body, is the underbeam of Double handle saddle below the Double handle saddle body, and putting the beams in place is double-decker, put the beams in place along porose on the line of centers, the hole pass upper beam about layer.

Described upper beam is Φ 18 along the aperture on the line of centers, last deck-siding 40mm, and thick 30mm, layer distance is 18mm about upper beam.

Two elongated slots inboard and that split with line of centers are apart from being 40mm about described double hook, and elongated slot two pitch-rows are 31mm.

Described perforate distance along the upper and lower beam on the line of centers is 95mm.

The underbeam of described Double handle saddle is along porose on the line of centers.

Described Double handle saddle body is the metal paattern forging.

Characteristics of the present utility model are: because whole metal die forging and the turnning and milling technology of adopting strengthens Double handle saddle body intensity greatly, not can owing to the existence of foundry technique to Effect on Performance.

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 embodiment front view structural representation;

Fig. 2 is the utility model embodiment lateral plan structural representation.

Among the figure, 1, the saddle body; 2, double hook; 3, put the beams in place; 4, line of centers; 5, go up the hole; 6; Elongated slot 7, following hole; 8, underbeam; 9, layer about.

The specific embodiment:

As shown in Figure 1, forge and press out an ears saddle body 1 by the metal paattern forging process, Double handle saddle body 1 is a symmetric body, and there is crooked double hook 2 at left and right two ends; Double hook about 2 is inboard to have elongated slot 6 with 4 pairs of line of centerss, and elongated slot 6 has distance to plate at the bottom of, and inboard and are 40mm with two elongated slots distances that line of centers is split about double hook, elongated slot two pitch-rows are 31mm.Elongated slot 6 respectively has a hole up and down; Being the upper beam 3 of Double handle saddle above Double handle saddle body 1, is the underbeam 8 of Double handle saddle below the Double handle saddle body.

As shown in Figure 2, upper beam 3 is double-deck, puts the beams in place 3 along porose on the line of centers, layer 9 about the hole is passed; Putting the beams in place 3 is Φ 18 along the aperture on the line of centers, last deck-siding 40mm, thick 30mm, at the underbeam 8 of Double handle saddle along also porose on the line of centers.Along the perforate of the upper and lower beam of line of centers 4 apart from being 95mm.3 the bilayer of putting the beams in place adopts turnning and milling technology, goes out wide 18mm groove from 3 the top turnning and milling of putting the beams in place, and bottom land is the semicircle of 9mm.
