Abstract

The utility model relates to an anchor positioning clamp; the upper end surface of a clamp body is V-shaped, and U-shaped bolts are fixed on both ends of the V-shaped surface and arranged above; a pin is fixed on the lower end of the clamp body; the pin is hinged with a lower splint; the lower splint is connected with an upper splint through a straight bolt; and the inner side of the lower splint and the inner side of the upper splint are provided with symmetric circular arc-shaped wire ducts. The anchor positioning clamp has high overall structural strength, bears large load, fixes a contact line particularly by adopting a full-wrapping structure and can well prevent the contact line from slipping off from the clamp, so that the running safety is greatly improved, so as to fully meet the design and the operation requirements of a high-speed electrified railway in structure and performance.

Description

Anchor props up positioning checkpoint

Technical field

The utility model relates to a kind of anchor and props up positioning checkpoint, belongs to electrification railway contact net Parts manufacturing technology field.

Background technology

In the electrification railway contact net, need registration device to realize the fixing of contact wire at transition mast inoperative locating point place.Anchor props up positioning checkpoint and belongs to key components and parts in the registration device, its effect is by the fixing contact wire of wire clamp, makes contact wire be transformed into control position from anchorage, therefore, anchor prop up positioning checkpoint bear contact wire in the horizontal direction with the tension force component of vertical direction, stressed bigger.The high-speed electric railway thread tension force is far above general circuit, and along with continuous impact more speed, the tension force that casts anchor is more and more higher, and anchor props up loading that positioning checkpoint bears also in continuous increase.It is less that anchor of the prior art props up positioning checkpoint work loading, be difficult to satisfy the requirement of high-speed electric railway, the fixing contact wire of the groove of the wire clamp on it by the clamping contact wire particularly, the contact surface of wire clamp and contact wire is little, easily slippage from wire clamp of contact wire threatens traffic safety.

Summary of the invention

The technical matters that the utility model solves: design a kind of anchor and prop up positioning checkpoint, the overall construction intensity height, the loading of carrying is big, particularly adopt fixedly contact wire of full package structure, can better prevent contact wire slippage from wire clamp, travel safety improves greatly, can satisfy the design and running requirement of high-speed electric railway on structure and the performance fully.

The technical solution adopted in the utility model: a kind of anchor props up positioning checkpoint, comprise clamp body, U-bolt, V-shaped of the upper surface of clamp body, U-bolt is fixed on the two ends of " V " profile and is positioned at its top, the lower end of clamp body is fixed with pin, be hinged with lower plate on the pin, by straight bolted connection train wheel bridge arranged on the lower plate, and the inboard of lower plate and train wheel bridge is shaped on symmetrical circular arc wire casing.

The lower end of described pin is shaped on circular groove, the upper end of lower plate is shaped on vertical connecting bore, the upper end level of lower plate is shaped on two pin holes, and two pin holes connect with the inwall of connecting bore respectively, pin is inserted in the connecting bore, the open end of U type set pin is inserted on two pin holes and is arranged in circular groove, and lower plate is hinged on the pin.

The left end of described lower plate is horizontally hinged on pin, and right-hand member tilts, and is shaped on anti-slop serrations on the circular arc wire casing of lower plate and train wheel bridge inboard.

Described circular arc wire casing is positioned at the top of straight bolt.

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

1, the utility model clamp body adopts aluminium alloy casting to make, and train wheel bridge and lower plate are forged by Cu alloy material and form, the intensity height, and the loading of carrying is big, and reasonable integral structure, and Installation and Debugging are convenient, can satisfy the requirement of high-speed electric railway fully.

2, the utility model adopts fixedly contact wire of full package structure, can better prevent clue slippage from wire clamp, has further improved the overall work loading, and travel safety is improved greatly.

3, the utility model line train wheel bridge and lower plate material are copper alloy, and be identical with the contact wire material, can avoid the unlike material potential corrosion.

The specific embodiment

1,2,3 and 4 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.

A kind of anchor props up positioning checkpoint, comprises clamp body 1, U-bolt 2, V-shaped 3 of the upper surface of clamp body 1, and U-bolt 2 is fixed on the two ends of V-type face 3 and is positioned at its top, and the lower end riveted joint of clamp body 1 has pin 4.The lower end of pin 4 is shaped on circular groove 9, the upper end of lower plate 5 is shaped on vertical connecting bore 10, the upper end level of lower plate 5 is shaped on two pin holes 11, and two pin holes 11 connect with the inwall of connecting bore 10 respectively, pin 4 is inserted in the connecting bore 10, the open end of U type set pin 12 is inserted on two pin holes 11 and is arranged in circular groove 9, and the left end of lower plate 5 is horizontally hinged on pin 4, make lower plate 5 can around pin 4 carry out 360 the degree rotations and can be from slippage on the pin 4.The right-hand member of lower plate 5 tilts, and is connected with train wheel bridge 7 by straight bolt 6, and the inboard of lower plate 5 and train wheel bridge 7 is shaped on symmetrical circular arc wire casing 8.Circular arc wire casing 8 is positioned at the top of straight bolt 6.Be shaped on anti-slop serrations 16 on the circular arc wire casing 8.

Clamp body 1 adopts aluminium alloy casting to make; Train wheel bridge 5 is forged by Cu alloy material with lower plate 7 and forms; U type set pin 12 adopts stainless steel precision to be processed into.

Installation and application: at first clamp body 1 is connected on the registration arm 13 by U-bolt 2, U-bolt 2 does not apply predetermincd tension at this moment, then contact wire 14 is placed circular arc wire casing 8, straight bolt 6 passes in the screw of through hole 15 spinnings on train wheel bridge 7 on the lower plate 5 train wheel bridge 7 is fixing with lower plate 5, contact wire 14 is wrapped in the circular arc wire casing 8 entirely, adjust the stagger of contact wire 14 simultaneously, last fastening U-bolt 2 gets final product to the specified tightening force square.
