Abstract
The utility model relates to a central anchor joint cable clamp of carrier cables, wherein an unthreaded hole (6) is made on the left side of an upper clamping plate (1) of the clamp, a stop threadedhole (7) is made on the right side, an unthreaded hole (8) is made on the left side of a middle clamping plate (2), linking threaded holes (9) are made on two sides of the lower clamping plate (3), the middle clamping plate (2) is located on the left half portion between the upper clamping plate (1) and the middle clamping plate (2), a long screw bolt (5) orderly penetrates through the unthreadedhole (6) on the left side of the upper clamping plate (1) and the unthreaded hole (8) on the left side of the middle clamping palter (2), and is screwed on the linking threaded holes (9) on the left side of the lower clamping plate (3), and a neck down bolt (4) is screwed on the stop threaded hole (7) on the right side of the upper clamping plate (1) and the linking threaded holes (9) on the rightside of the lower clamping plate (3). The clamp can be installed on a cable without taking off the screw bolt, the installation is convenient, and the construction efficiency is greatly improved. Theneck down bolt can not deviate from the whole assembly during installation, and can not drop and hurt people or be lost, thereby the safety property of parts is improved.
Description
Technical field
The utility model relates to a kind of Mid-point clamp for messenger wire, belongs to contact nets in electrified railways Parts manufacturing technology field.
Background technology
The middle part of contact nets in electrified railways chain type hanging all will add mid point anchor, and is moving to anchor Duan Yiduan string when preventing to compensate, and also can dwindle the accident scope when the broken string accident takes place.Mid-point clamp for messenger wire is exactly fixing the tie knots strength member of clue of catenary and anchor in mid point anchor place that is used in each anchor section, and how the performance of Mid-point clamp for messenger wire directly has influence on the safety of whole contact nets in electrified railways.At present the Mid-point clamp for messenger wire of contact nets in electrified railways adopts three clamping plate in four straight bolted connection upper, middle and lower, four bolts need be withdrawed from from three clamping plate fully during installation, installs complicatedly, and operating efficiency is low.
Summary of the invention
The technical matters that the utility model solves: design a kind of Mid-point clamp for messenger wire, need not during installation bolt is taken off, easy for installation, operating efficiency improves greatly.
Technical solution of the present utility model: a kind of Mid-point clamp for messenger wire, comprise train wheel bridge, middle clamp plate and lower plate, the left side of train wheel bridge is shaped on unthreaded hole, and the right side is shaped on the retaining tapped bore, the left side of middle clamp plate is shaped on unthreaded hole, and the both sides of lower plate all are shaped on the connection tapped bore; The left side of middle clamp plate between train wheel bridge and middle clamp plate, overbolt passes the unthreaded hole spinning in the unthreaded hole in train wheel bridge left side and middle clamp plate left side successively on the connection tapped bore in lower plate left side, and necking down bolt spinning is on the connection tapped bore on the retaining tapped bore on train wheel bridge right side and lower plate right side.
Described train wheel bridge left side is shaped on two unthreaded holes, and the right side is shaped on two retaining tapped bore; The left side of middle clamp plate is shaped on two unthreaded holes, and the both sides of lower plate all are shaped on two and connect tapped bore.
Described train wheel bridge, middle clamp plate and lower plate all adopt Cu alloy material to make.
Advantage that the utility model compared with prior art has and effect:
Need not bolt is just taken off and can install on clue when 1, the utility model is installed, easy for installation, operating efficiency improves greatly.
Necking down bolt when 2, the utility model is installed can not cause dropping and hurt sb.'s feelings or lose because not the stopping of retaining screw thread on the train wheel bridge can break away from whole assembly, has improved the safety performance of part.
3, the utility model adopts the phenomenon that the tapped bore of copper alloy body can avoid stainless steel bolt to kill.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings:
A kind of Mid-point clamp for messenger wire comprises train wheel bridge 1, middle clamp plate 2 and lower plate 3, and train wheel bridge 1 and inboard, lower plate 3 middle part all are shaped on wire casing 10, and middle clamp plate 2 right-hand members all are shaped on wire casing 11 in both sides up and down; The left side of train wheel bridge 1 is shaped on two unthreaded holes 6, and the right side is shaped on two retaining tapped bore 7, and the left side of middle clamp plate 2 is shaped on two unthreaded holes 8, and the both sides of lower plate 3 all are shaped on two and connect tapped bore 9; The left side of middle clamp plate 2 between train wheel bridge 1 and middle clamp plate 2, overbolt 5 passes unthreaded hole 8 spinnings in the unthreaded hole 6 in train wheel bridge 1 left side and middle clamp plate 2 left sides successively on the connection tapped bore 9 in lower plate 3 left sides, and necking down bolt 4 spinnings are on the connection tapped bore 9 on the retaining tapped bore 7 on train wheel bridge 1 right side and lower plate 3 right sides.Train wheel bridge 1, middle clamp plate 2 and lower plate 3 all adopt Cu alloy material to make.
Installation and application: unclamp overbolt 5 during installation, necking down bolt 4 whiz lower plates 3, overbolt 5 unclamps enough distances but keeps three ply wood still to connect together, and necking down this moment bolt can not cause dropping and hurt sb.'s feelings or lose because not the stopping of retaining screw thread on the train wheel bridge 1 can break away from whole assembly.Then middle clamp plate 2 and lower plate 3 are drawn back successively along overbolt 5 axis, fixing catenary 12 is sticked into the wire casing 11 of the wire casing 10 of train wheel bridge 1 inboard and middle clamp plate 2 upsides from necking down bolt 4 one sides, the anchor clue 13 of tiing knots sticks into the wire casing 11 of the wire casing 10 of lower plate 3 inboards and middle clamp plate 2 downsides from necking down bolt 4 one sides, tighten successively overbolt 5 and necking down bolt 4 fixedly catenary 12 and the anchor clue 13 anchors knot of tiing knots be in the same place.
