Abstract

The invention relates to a design method for using gold tool in electrified railroad contact net which is a method for designing binaural cradle of hanging clue in electrified railroad contact net system. The character is that the binaural cradle adopts metallic die forging. The binaural cradle body is symmetrical body, and both ends have bending double-hook; elongated slot is opened on the left and right inner side of double-hook and has a distance to the bottom of plate; two holes are arranged on the top and bottom of elongated slot; the overhead is arranged on the upper part of binaural cradle body, while its lower part has inderbeam of binaural cradle body; overhead two-layer trenching adopts milling craft; a hole is arranged on overhead along center line which through the left and right layers of overhead. The diameter of the hole is Phi 18, the width of overhead is 40mm, and the thickness is 30mm, the distance of left and right layers of overhead is 18mm.

Description

The method of designing of Double handle saddle

Affiliated technical field:

The present invention relates to the method for designing of the gold utensil that uses in a kind of railway contact line, be applicable to the method for designing that hangs the Double handle saddle of 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 method of designing that the purpose of this invention is to provide a kind of Double handle saddle, its design-calculated Double handle saddle intensity height can satisfy the influence that thread tension force increases behind the speed increase in vehicle.

The object of the present invention is achieved like this, and a kind of method of designing of Double handle saddle is provided, and it is characterized in that: the Double handle saddle body adopts the metal paattern forging.

Described 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; Be the upper beam of Double handle saddle above the Double handle saddle body, at the underbeam of the lower foot Double handle saddle of Double handle saddle body, the upper beam bilayer is opened shelves and is adopted a turnning and milling processes, 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 porose along design on the line of centers.

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

The invention will be further described below in conjunction with the embodiment accompanying drawing:

Description of drawings:

Fig. 1 is an embodiment of the invention master TV structure scheme drawing;

Fig. 2 is an embodiment of the invention side-looking 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.
