Abstract

The utility model discloses a contact net carrier cable string hanging wire clamp. A main board 1 is connected with an elastic ring 4 which is provided with a hanging hook 6. A main shaft 8 of a support ear 2 is connected with a pressing handle 13 which is provided with a long hole 5. A back hanging hook is matched with an opening 12 of a locking buckle 11, wherein, a catenary 14 is fastened by the back hanging hook, and a bulge 9 which is matched with the main shaft is arranged on the locking buckle.

Description

Contact system catenary hanger ear

The utility model relates to a kind of hanger ear of electrification railway contact net catenary, belongs to railway power supply equipment scope.

For many years, the hanger ear between electrification railway contact net catenary and contact wire is to continue to use the bolt-tightened type clamping plate always, and its structure is respectively to establish half arc groove at two metal splint inner faces, and a screw is respectively arranged on the clamping plate.During use with two clamping plate relatively and clamp behind the catenary again by bolted.The wire clamp of this structure brings very big inconvenience to aloft work, and speed of application is slow; In train operation, can cause the wire clamp loose or dislocation sometimes or damage the exocuticle of catenary because of play; Also because of this wire clamp is exposed in the air all the year round, dust and sleet are easy to cause the corrosion of wire clamp and bolt to become rusty extremely, cause difficulty to maintenance.

The purpose of this utility model is exactly for solving existing defective in the above-mentioned background technology, and provides a kind of non-bolt to connect, and can improve construction and maintenance work efficient, easily adorn hanger ear readily removable, dependable performance.

To achieve these goals, the utility model proposes the corresponding techniques solution:

This contact system catenary hanger ear is that mainly the resilient ring that has hook is connected with mainboard, opening on the snap close cooperates with hook, snap close is provided with the projection that cooperates with main shaft, and has a slotted hole on the main shaft bonded assembly pressure handle, and main shaft is supported by the journal stirrup on the mainboard.Be positioned at the slotted hole of pressure handle with the two ends of the friction tight little axle of snap close.Pressure handle is connected on the main shaft, is provided with flanging on journal stirrup.The radius of curvature and the catenary of resilient ring and flanging match.

Fig. 1: structural representation of the present utility model.

Fig. 2: with the constitution diagram after catenary cooperates.

Now reach embodiment in conjunction with the accompanying drawings the utility model is done a detailed description.

As shown in Figure 1, this wire clamp mainly is by mainboard 1, resilient ring 4, snap close 11, pressure handle 13, main shaft 8 and little axle 10 several component set-ups.Wherein, on mainboard 1, be provided with two journal stirrups 2, have inside flanging 3 on the journal stirrup 2.Resilient ring 4 as shown in the figure is connected with mainboard 1 by groove 7, and an end of resilient ring 4 is provided with a hook 6.Main shaft 8 flexibly connects with journal stirrup 2, and pressure handle 13 is connected on the main shaft 8.Little axle 10 is interference fit with the snap close 11 that has opening 12, and the two ends of little axle 10 lay respectively in the slotted hole 5 of pressure handle 13.On mainboard 1 and pressure handle 13, also respectively establish a through hole that can pass pin.The radius of curvature and the catenary of resilient ring 4 and flanging 3 match, and the design of flanging 3 is the damages that can avoid the edging of journal stirrup 2 that catenary is caused, have also strengthened the contact surface of this wire clamp and catenary simultaneously, have improved its contact performance.

This wire clamp in use, only need catenary 14 is placed between resilient ring 4 and the flanging 3, depress resilient ring 4 and make hook 6 be articulated in opening 12 places of snap close 11, depress pressure handle 13 then and promptly finish installation (referring to Fig. 2) by pin cross-under mainboard 1, dropper 15 and pressure handle 13.In the process of depressing pressure handle 13, the projection 9 on the snap close 11 buckles self-locking with main shaft 8, and the stroke of its projection 9 is satisfied by the size of slotted hole 5 just.Because the pressure of resilient ring 4 exists, behind projection 9 and main shaft 8 flush fits, just can not occur again getting loose, unless just pull out pin with instrument prize can make behind the pressure handle 13 this wire clamp again row open.

The utility model compared with prior art has the following advantages: 1, connect without bolt, install Dismantle efficient and conveniently, can increase work efficiency. 2, compression joint area is big, clamping force is strong, and is in service Can get loose phenomenon. 3, can to carrier cable exocuticle injury, not prolong carrier cable and use the longevity Life, saving substantial contribution. 4, simple in structure, easy manufacturing is fit on the electrification railway contact net The a large amount of use.
