Description

It is a kind of double to hold double overhead contact lines of leading and cast anchor specific purpose tool

Technical field

It is the utility model relates to a kind of specific purpose tool, in particular to a kind of double to hold double overhead contact lines of leading and cast anchor special tool Tool.

Background technique

Existing contact net pair holds double lead and casts anchor mainly when falling anchor using the equalizer pulley of a set of φ=200mm and one The Line tool is grabbed in the wirerope connection of φ 14mm long 3m, and the tension that casts anchor of two branch lines is tightened to specified by manual stringing tool Power completion falls anchor work, and equalizer pulley main function is to be used cooperatively wirerope in stringing tool stringing and grab the Line tool, leads to It crosses and reaches balanced in the tension that equalizer pulley freely adjusts two branch lines after wirerope stress and ensure quality of casting anchor later.

There are problems:

1., that the formal connecting component of casting anchor influences two lines when the playback of carrier cable back skating is contour；

2., contact wire lower anchoring turns face cannot freely go to normal condition；

3., freely back skating period of the day from 11 p.m. to 1 a.m resistance is greater than that equalizer pulley, cast anchor interconnecting piece to connecting component of formally casting anchor after balanced tension Part is without freely turning face device.

Utility model content

It holds double overhead contact lines of leading the purpose of this utility model is to provide a kind of double and casts anchor specific purpose tool, it is above-mentioned to solve The contact wire lower anchoring proposed in background technique turn face cannot freely go to normal condition, the problem of.

To achieve the above object, the utility model provides the following technical solutions: a kind of double hold double lead overhead contact line and casts anchor Specific purpose tool, including mounting ring, U-shaped strap and equalizer pulley, one end of the mounting ring through pin shaft rotation by connecting It is connected to U-shaped strap, the inside of the U-shaped strap is equipped with equalizer pulley, runs through at the center of the equalizer pulley and set There is jackshaft, the two sides of the U-shaped strap are fixed with protecting box, and the outer cover of the equalizer pulley is equipped with rope, The both ends of the rope are mounted on rotator, and one end of the rotator is connected with terminal clamp by connection sheet.

As a kind of optimal technical scheme of the utility model, the both ends of the jackshaft extend through two protecting box Sidewall thread is connected with clamping screw.

As a kind of optimal technical scheme of the utility model, the side on the protecting box top offers fuel feed hole, institute The bottom for stating fuel feed hole is fixed with oil guide pipe, and the top of the fuel feed hole is connected together and has blanking cover.

As a kind of optimal technical scheme of the utility model, one end of the terminal clamp and one end of connection sheet are run through Equipped with connecting shaft, the both ends of the connecting shaft are threaded with fixing bolt.

As a kind of optimal technical scheme of the utility model, the model SXL-5 of the rotator.

Compared with prior art, the utility model has the beneficial effects that the utility model a kind of pair is held double net-faults that connect and hanged Extension casts anchor specific purpose tool, and after so that carrier cable erection is finished the playback of back skating, two lines are naturally contour, are especially embodied in curve on gram The problem of two supporting force ropes at curve are not contour and height difference is greater than hardness standard 5mm is taken, stringing precision is improved, reduces into Product error, in addition to carrier cable because caused by artificial unwrapping wire clue reverse the problem of cannot diffusing from slew after a few and also be had The solution of effect；After contact line erection finishes the sub- mounting and positioning device of back skating, contact line line face rapid and natural can be made straight to just Normal state especially can return back to normal condition before plasticity variation occurs for contact line in one across inoperative branch line face of place of casting anchor, Ensure that ratchet compensating device stabilizer is unbiased；In addition two contact line working faces and rail plane line at curve are effectively solved Not parallel and reversed double the problem of propping up not contour phenomenon, (i.e. since both threads rope receiving tension is unequal, cause two clues to work The line of point is not parallel with rail plane line and reversely intersects, to make pantograph and the unbalanced mill of double branch contact line working faces Consumption), more preferably two-wire provides balancing tension guarantee.
