Abstract

A new adjustable whole hanger is provided. The utility model comprises a catenary wire clamp (1) which takes the shape of an inverse U structure, and two flanges (4) along the circumferential direction of the upper edge of the outer wall, a groove bolt (5) that is arranged below the catenary wire clamp (1), and a hanger line (2) which is fixed on a contact wire clamp (3) with the lower end, while the upper end of the hanger line (2) is positioned between two flanges (4) by winding through the catenary wire clamp (1) and is also blocked in a truncking (6) on the groove bolt (5) at the two sides of the catenary wire clamp (1), as well as a screw nut (7) which is sleeved on one side of the remaining head of the hanger line. The utility model, by directly winding the hanger line on the catenary wire clamp body, and the regulating bolt and fastening bolt adopt the same bolt, realizes the regulation and installation. Thus the utility model has the advantages of simple and novel structure and convenient mounting, debugging and maintenance. Moreover, the lower end of the hanger line is directly connected on the contact wire clamp through a suspension ring, in doing so a transition component and the materials are saved, and the cost reduction is lowered as well.

Description

The new type of adjustable dropper

Technical field

The utility model relates to a kind of new type of adjustable dropper.

Background technology

The dropper device is to be widely used in indispensable important component part in the electrified contacting nets suspension in recent years.The dropper device that adopts is divided into two kinds basically at present: whole compression joint type and whole adjustable.Whole adjustable dropper device is owing to reduced difficulty of construction and good adjustable is widely used especially.The mode of operation of existing whole adjustable dropper device is, hanger ear utilizes bolted to be installed on catenary or the contact wire, the dropper line hung on wire clamp annex-suspension ring on thimble with being connected all of two end terminals, the length of adjustment dropper line is undertaken by the adjustable bolt of independent setting, part is more, installs, debugs and the maintenance inconvenience.

Summary of the invention

The technical matters that the utility model solves: design a kind of new type of adjustable dropper, the dropper line is directly on the Horizontal messenger wire clamp body, adjustable bolt and binding bolt merge bolt of employing, realize simultaneously adjusting and installing a position, simple in structure, novel, installation, debugging and easy to maintenance.In addition, the lower end of dropper line on the contact wire wire clamp, has been saved a transition part by the suspension ring direct connection, has saved material, has reduced cost.

Technical solution of the present utility model: a kind of new type of adjustable dropper, comprise Horizontal messenger wire clamp (1), dropper line (2) and contact wire wire clamp (3), Horizontal messenger wire clamp (1) is down " U " structure, the outer wall upper edge circumferentially is shaped on two flanges (4), fluting bolt (5) is installed in the lower end of Horizontal messenger wire clamp (1), dropper line (2) lower end is fixed on the contact wire wire clamp (3), the upper end is walked around Horizontal messenger wire clamp (1) and is positioned at location between two flanges (4), and in the both sides of Horizontal messenger wire clamp (1) were stuck in wire casing (6) on fluting bolt (5), remainder one side was set with nut (7).

Along laterally being shaped on flange (8) and (9), and flange (8) and (9) are positioned at down the bottom of " U " structure arc section, catenary (10) are installed on the arc section of Horizontal messenger wire clamp (1) on the inwall of Horizontal messenger wire clamp (1) both sides.Also be pressed with fixedly fixture block (11) in the wire casing (6) of remainder one side of fluting bolt (5), and fixedly fixture block (11) is positioned at the inboard of nut (7).

The lower end of dropper line (2) is fixed on the suspension ring (12), contact wire wire clamp (3) is down " U " structure, and the upper end inwall (13) of contact wire wire clamp (3) is along laterally making the circular arc that matches with suspension ring (12), and suspension ring (12) directly are sleeved on the upper end of contact wire wire clamp (3).

Advantage that the utility model compared with prior art has and effect:

1, directly on the Horizontal messenger wire clamp body, dropper adjustable bolt and Horizontal messenger wire clamp binding bolt merge bolt of employing to the dropper line, realize simultaneously a position adjusting and installing, and be simple in structure, novel, installation, debugging and easy to maintenance.

2, the lower end of dropper line on the contact wire wire clamp, has been saved a transition part by the suspension ring direct connection, has saved material, has reduced cost.

3, adjusts and to adopt the fixedly fixture block of band locking plate to fix between side dropper line and the nut, not only can prevent slot interior receipts, line ball, and the locking plate that can break off with the fingers and thumb after fastening on the fixing fixture block prevents nut loosening that reliability is higher.

Fig. 3 is the structural representation of the utility model fluting bolt.

The specific embodiment

1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.

A kind of new type of adjustable dropper, its Horizontal messenger wire clamp (1) is down " U " structure, and the outer wall upper edge circumferentially is shaped on two flanges (4), and fluting bolt (5) is installed in the lower end of Horizontal messenger wire clamp (1).The lower end of dropper line (2) is fixed on the suspension ring (12), contact wire wire clamp (3) is down " U " structure, and the upper end inwall (13) of contact wire wire clamp (3) is along laterally making the circular arc that matches with suspension ring (12), and suspension ring (12) directly are sleeved on the upper end of contact wire wire clamp (3).The upper end of dropper line (2) is walked around Horizontal messenger wire clamp (1) and is positioned between two flanges (4) location, and in the both sides of Horizontal messenger wire clamp (1) were stuck in wire casing (6) on the fluting bolt (5), remainder one side was set with nut (7).

Using method: contact wire wire clamp (3) is clamped on the contact wire (14), and Horizontal messenger wire clamp (1) is clamped on the catenary (10).When regulating the dropper line length, unclamp nut (7), the dropper line (2) of twitching Horizontal messenger wire clamp (1) both sides is to appropriate size, straining dropper line (2) then makes it tightly on Horizontal messenger wire clamp (1) outer wall, and be positioned at location between two flanges (4), fastening nut (7) clamps Horizontal messenger wire clamp (1), catenary (10) is installed on the arc section of Horizontal messenger wire clamp (1) by the flange (8) on the inwall of Horizontal messenger wire clamp (1) both sides and (9).Having broken locking plate on the fixing fixture block (11) at last off with the fingers and thumb prevents that nut (7) is loosening and gets final product.
