FR2811945A1 - Catenary cable bracket for mast supporting overhead electrical lines used for trams or trolley buses, has bracket mounted on mast with tooth and rack adjustment for bracket position - Google Patents

Abstract

The catenary cable bracket has height adjustment and indexing positional adjustment for the anchor between the bracket, the mast and an insulator (1) at the end of the bracket. The adjustment can include a rack (3) mounted longitudinally on the mast (2) cooperating with teeth (21,22) on the bracket base.

Description

The present invention relates to a new device for fixing a

overhead console on a mast.

  The invention relates more precisely to the system for fixing the console pad to a mast supporting one or more suspended electric lines, called catenary lines, used for the electric supply of trams or trolley buses. Generally such fastening systems are difficult to adjust in altitude. There is however a model, which is adjustable in altitude, by means of a strap or strapping. Its disadvantages are in particular the following - the modification of altitude is not possible without deterioration - its implementation requires specific tools - it includes undesirable projections - it does not include pre-indexed positions; - it does not allow the recovery of forces in the vertical direction; - it is unsightly; The object of the invention is to overcome these drawbacks by using elements which are easy to set up and which allow the altitude of the altitude to be easily adjusted.

  console with simple tools, while offering acceptable aesthetics.

  This object is achieved by the invention which consists of a device for fixing o a catenary line console on a mast supporting said line, characterized in that it comprises, in combination, height adjustment and indexing means according to a plurality of determined positions and an element called console shoe

  serving as an interface between the mast and a console end isolator.

  More particularly the device consists of a system comprising at least one rack provided longitudinally on the mast cooperating with at least

  toothing provided on the console shoe.

  According to a first variant, it consists of a blind front rack with central groove for the installation of two strips on which the

  flat console shoe secured to the insulator by an intermediate bracket.

  3o In a second variant it consists, on the one hand in two symmetrical longitudinal racks along the mast, and on the other hand in a console shoe in

  sleeve shape opening by a flap.

  According to the second variant, the two racks are offset by

  predetermined distance from the mast axis and are toothed racks.

  According to the second variant, the console shoe is formed of a fixed flap and

of an opening shutter.

  The invention will be better understood using the description below made in

  reference to the following appended figures: - Figure 1 'general view of a first fixing variant according to the invention - Figure 2: vertical section view of the variant of Figure 1; - Figure 3: exploded view of the variant of Figure 1; - Figure 4: side view of a second fixing variant according to the invention; - Figure 5: detail view of Figure 4; Figure 6: normal tilted top view relating to the variant of Figure 4;

  - Figure 7: sectional view along AA of Figure 4.

  According to the variant of FIGS. 1 to 3, the isolator (1) of a console end (not shown) is fixed to a mast (2) by a rack system comprising on the one hand a rack (3) provided longitudinally , in the frontal position, along the mast (2), on the other hand of a flat console shoe (4), with serrated underside, the toothing (22) of which is complementary to that of the rack so as to cooperate with

said rack (3).

  Preferably but not necessarily, the rack (3) is not a rack mounted on the mast, it is a blind rack molded in hollow

In this one.

  This arrangement has the advantage of avoiding protrusions on the mast, and of

  make a rainproof fastening.

  In addition, the rack (3) has a longitudinal central groove (7) for the installation of two strips (5) on which the console shoe is fixed by two screws (6). The console pad is secured to the insulator (1) for example by an intermediate stirrup (8) conventionally held by an axis (9), between two

skate ears (10) (4).

  The positioning of the console shoe in the chosen position is easy and

made without specific tools.

  The number of possible positions is determined by the pitch and the length of

  the rack and can be important.

  Reference is now made to FIGS. 4 to 7 of a second variant of

realization of the invention.

  The mast (2) has two side blind racks (20) arranged symmetrically along the mast, each cooperating with a toothing (21a, 21b)

  provided on a console pad, in the form of a sleeve opening in two parts.

  Preferably, the two racks (20) are offset by a distance (d) from the axis of the mast so as to allow the fitting of the sleeve without creating any

protrusions from the mast.

  This feature is visible in Figure 6 which shows that the curvature (11) of

  side walls of the sleeve is in the extension of the curvature (12) of the mast.

  This arrangement requires racks that are shallower than that of the

  first variant, hence the choice of racks with flat teeth (Figure 7).

  The console shoe (4) comprises a fixed flap (13) with an annular part (13a) for fixing the insulator and an opening flap (14) whose opening plane (15) passes through the longitudinal axis (16) of the mast, and has a positioning groove. The console shoe also has a flat upper face (18) and a rounded lower shape (19), on the one hand in the vertical plane perpendicular to the direction of the insulator, and on the other hand in the extension of the plane. opening (15)

  along a radius of curvature (R) (Figure 4).

  The console shoe is first opened, then its fixed toothing (21a) is fitted at the chosen height, then the opening flap (14) is positioned thanks to its removable toothing (21b) and to its positioning ribs (17) , finally we lock the pad

  console by means of a bolt (23) perpendicular to the opening plane (15).

  Among the advantages of these two alternative embodiments, it will be noted that the use of rack makes it possible to have a fixing adjustable in height and indexable according to predetermined positions without damaging any of the parts; - installation without special tools - recovery of vertical forces by racks with flat teeth, - absence of undesirable projections;

  o - significantly improved aesthetic appearance.
