Abstract
The invention provides a novel terminal-anchoring wire clamp for contact wires, which consists of a double-ear bolt (1), a sleeve (2), a wedge sleeve (3) and a wedge (4), wherein the bottom of the sleeve (2) is provided with a wire hole (7); an inner thread is arranged on the inner wall of the upper end of the sleeve (2); the wedge sleeve (3) is positioned on the lower part of the sleeve (2); the wedge (4) is inserted in the wedge sleeve (3); the wedge (4) and the wedge sleeve (3) fit each other through a conical surface; the lower end of the double-ear bolt (1) is axially provided with a through hole (9) and is screwed at the upper end of the sleeve (2) through an outer thread on the lower end of the double-ear bolt (1); the upper end of the double-ear bolt (1) is provided with a connection hole (8); a pin (5) is inserted on the connection hole (8); and a cotter pin (6) is arranged on the pin (5). The wire clamp has the advantages of meeting application requirements of high-speed high-tension heavy-load wires, greatly improving the safety and reliability of anchoring installation and breaking connection and ensuring more superior safety performance of a whole electrified contact net, along with simple structure, short manufacturing cycle, convenient installation, debugging and maintenance.
Description
Technical field
The present invention relates to a kind of novel terminal-anchoring wire clamp for contact wires, belong to contact nets in electrified railways Parts manufacturing technology field.
Background technology
The contact wire of contact nets in electrified railways in use all needs segmentation to cast anchor inevitably or disjunction connects, termination fitting for contact wire is exactly to be used for the strength member that the contact wire termination connects with other parts, and how the performance of terminal anchoring clamp directly has influence on the safety of whole electrified contacting nets.With the immediate prior art of the present invention is to bore tube (ears) bolt type terminal anchoring clamp and template ears taper sleeve type terminal anchoring clamp.Awl tube (ears) bolt type terminal anchoring clamp complex structure, install inconvenient, manufacturing cost is high, compatible with environment is poor; Though template ears taper sleeve type terminal anchoring clamp is produced, installation, convenient, be not suitable for the clue operating needs of hightension, heavy lift.
Summary of the invention
The technical matters that the present invention solves: design a kind of novel terminal-anchoring wire clamp for contact wires, not only simple in structure, manufacturing cycle is short, installation, debugging and easy to maintenance, and can satisfy the operating needs of high speed, hightension, heavy lift clue, having improved the safety and the reliability of cast anchor installation and disjunction connection, having made the safety performance of whole electrified contacting nets more superior.
Technical solution of the present invention: a kind of novel terminal-anchoring wire clamp for contact wires, constitute by ears bolt (1), sleeve (2), cover of wedge (3) and chock (4), the bottom of sleeve (2) is shaped on line hole (7), be shaped on negative thread on the inwall of sleeve (2) upper end, cover of wedge (3) is positioned at the bottom of sleeve (2), chock (4) is inserted in the cover of wedge (3), passes through cone match between the two; The lower end of ears bolt (1) axially is shaped on through hole (9), and is contained in the upper end of sleeve (2) by the external thread rotary on it, and the upper end of ears bolt (1) is shaped on connecting bore (8), is fitted with pin (5) on the connecting bore (8).
Be shaped on outer six side's boss (10) on the outer wall of described sleeve (2).Described ears bolt (1), sleeve (2) adopt behind the copper alloy forging forming machine to add and form, and cover of wedge (3), chock (4) adopt copper alloy bar to process.
The present invention is compared with prior art not only simple in structure, manufacturing cycle is short, installation, debugging and easy to maintenance, and can satisfy the operating needs of high speed, hightension, heavy lift clue, having improved the safety and the reliability of cast anchor installation and disjunction connection, having made the safety performance of whole electrified contacting nets more superior.In addition, the lower surface of ears bolt withstands on the large end face of chock can prevent that chock from withdrawing from, and has further improved catenary and has casted anchor and install and the safety and the reliability of disjunction connection.

The specific embodiment
1,2,3,4,5 a kind of embodiment of the present invention is described in conjunction with the accompanying drawings.
A kind of novel terminal-anchoring wire clamp for contact wires, constitute by ears bolt (1), sleeve (2), cover of wedge (3) and chock (4), the bottom of sleeve (2) is shaped on line hole (7), be shaped on negative thread on the inwall of sleeve (2) upper end, cover of wedge (3) is positioned at the bottom of sleeve (2), taper chock (4) is inserted in the internal taper hole on the cover of wedge (3), passes through cone match between the two; The lower end of ears bolt (1) axially is shaped on through hole (9), and the lower end of ears bolt (1) is contained in the upper end of sleeve (2) by the external thread rotary on it, the upper end of ears bolt (1) is shaped on connecting bore (8), is fitted with pin (5) on the connecting bore (8), and spring cotter (6) is housed on the pin (5).
Be shaped on outer six side's boss (10) on the outer wall of sleeve (2).Ears bolt (1), sleeve (2) adopt behind the copper alloy forging forming machine to add and form, and cover of wedge (3), chock (4) adopt copper alloy bar to process.Have anti-skidding screw thread on the inwall of taper chock (4), axially be evenly equipped with 4 tiny flutings (12), chock (4) can resilient radial be shunk.
Using method: after contact wire (11) passes the bottom outlet of the line hole (7) of sleeve (2) bottom and cover of wedge (3), pass chock (4) and pass from its big end, then the lower end of ears bolt (1) is screwed in the upper end of sleeve (2), and make contact wire (11) pass the through hole (9) of ears bolt.Screw the ears bolt and withstand chock it is moved vertically, cover of wedge (3) is carved urgent chock (4) radial shrinkage that makes with the conical surface of chock (4) and is stepped up contact wire.Go up plug-in mounting pin (5) at connecting bore (8) at last, on pin (5), put on spring cotter (6), the present invention is connected with other parts by pin (5).
