Definitions

  • the present invention relates to pole climbing irons' intended primarily to be used for climbing tapering poles.
  • the climbing iron comprises a shoe-support plate provided with a pole-abutment member, a gripping arm, and a connecting arm interconnecting the pole-abutment member and the gripping arm.
  • Pole climbing irons of-this type are in general use in construction and repair works on electric or telegraphic cables. When cables extend across rough country where it is impossible to use vehicles equipped with ladders or elevator platforms, pole climbing irons are the only practically useful tool at the linesman's disposal to reach the top of the pole.
  • Modern power-line poles have a standard length of 22 meters and are often made from concrete, since wooden poles of.this length and of acceptable quality are scarce today and consequently expensive. Wooden as well as concrete poles of any considerable length usually taper towards the top. This pole design combines considerable strength with comparatively lom meight.
  • the diameter of concrete poles having a length of 22 meters varies from appr. 510 millimeters at the base to appr. 180 millimeters at the top.
  • Conventional pole climbing irons cannot be used to climb poles showing such a considerable difference in diameters.
  • pole climbing irons which are intended to be used for climbing conical poles.
  • the iron extends upwards along the leg of the user to the level of his knee, at which point are positioned a support and a gripping arm which are interconnected by an adjustment mechanism.
  • the latter thus being positioned at knee--level, is manually operable by the user to adjust the climbing iron to the changes in diameter vertically along the pole.
  • this kind of climbing iron is heavy and clumsy and for this reason is not extensively used. Because the points of support of the climbing iron against the pole are positioned at knee-level where the user's range of movements relative to the pole is limited, this type of climbing iron is uncomfortable and inconvenient to use.
  • the pole climbing iron in accordance with the subject invention is intended to allow climbing of conically tapering poles with the same safety and agility as with conventional pole climbing irons used to climb poles having the same diameter throughout.
  • the climbing iron in accordance with the subject invention makes it possible to climb poles that are taller than the ones referred to above, e.g. about 45 meters,a pole height required for the 400 kU lines now being planned.
  • the climbing irons in accordance with the present invention are characterised in that the shoe-support plate to which is attached the pole-abutment member is connected with the connecting arm via a ratchet mechanism by means of which the shoe-support plate can be displaced relative to the connecting arm for adjustment to the gradually diminishing circumference of tapering poles.
  • the climbing iron shown in Fig. 1 comprises a shoe--support plate 1 with a pole-abutment member 2 thereon, a connecting arm 3, and a pole-gripping arm 4.
  • the shoe--support plate 1 is provided with the connecting arm 3 via a ratchet mechanism 5.
  • the pole abutment member 2 and the pole-gripping arm 4 abut against opposite sides of a cylindrical concrete pole 6 which tapers upwards from a maximum circumference (width) 7 to a minimum circumference (width) 8 at the top 9 of the pole.
  • Fig. 2 shows the climbing iron in a view from the side with a boot 10 secured to the shoe-support plate 1 with the aid of straps 1a.
  • the connecting arm 3 consists of two racks 11 and 12, the teeth of which are arranged in vertically facing relationship.
  • the racks 11 and 12 are rigidly interconnected at their ends by means of end pieces 13, the forward one, as seen in the toe direction, forming an attachment member on which the gripping arm 4 is mounted.
  • the ratchet mechanism 5 is provided with a shaft 14 (see Figs. 4 and 8) on which the shoe-support plate 1 is pivotally mounted.
  • a support arm 15 is rigidly connected at one of its ends to the mounting block 16 of the ratchet mechanism 5 while the opposite arm end serves to limit pivotment of the shoe-support plate 1 past a horizontal plane in alignment with the connecting arm 3.
  • the supporting end of the support arm 15 is connected to the shoe--support plate 1 by means of a spring means 17 in the form of a helical spring arranged to urge the shoe-support plate away from the support arm over a certain angular distance.
  • the pivotal movement of the shoe-support plate relative to the rest of the climbing iron appears from Fig. 3, showing the support plate with the boot thereon in the position at a maximum angle relative to the support arm.
  • the pivotal movement of the support plate 1 brings about a corresponding rotation of the shaft 14.
  • the shaft extends through the mounting block 16 which is formed with an upper channel 18 in which is mounted the upper rack 11, and with a lower channel 19 in which is mounted the lower rack 12.
  • the shaft 14 and its points 1b of attachment to the support plate 1 and mounting in the mounting block 16 appear from Fig. 4.
  • the shaft 14 is eccentrically mounted in the casing 16 in a cylindrical rotatable sleeve 20.
  • the sleeve bore in which the shaft 14 is mounted is positioned somewhat offset from the sleeve centre.
  • One of the points of attachment 1b is positioned at one of the outer ends of the shaft and the other one in a recess 21 formed in the sleeve 20.
  • the shaft 14 passes laterally through a double-rim cog wheel 22 which is mounted on the shaft via a hub 23 and is connected to the shaft by means of a free wheel 24 allowing the cog wheel 22 to run freely relative to the shaft in one rotational direction but blocking the cog wheel relative to the shaft in the opposite rotational direction.
  • a nut 25 locks the hub of the free wheel 24 relative to the shaft and a cap 26 protects the free-wheel interior from grit and dirt particles.
  • the inner gear rim 27 of the cog wheel 22 is in engagement with the upper rack 11 in the position illustrated in Fig. 4.
  • a locking arm 28 By pivoting a locking arm 28 over 180°, which arm is connected to the sleeve 20, it is possible to impart to the shaft a parallel movement inside the mounting block 16, whereby the gear rim 27 is moved to its position out of engagement with the upper rack 11 and into engagement with the lower rack 12.
  • a spring-loaded pawl 29 on the actuating lever 28 makes it possible to lock the latter in the two pivotal positions.
  • the free end of the shaft 14 is provided with an angular arm 30 which is arranged, upon pivotal movement of the shoe-support plate 1 to the upper end position thereof to actuate a pawl 31 engaging an outer gear rim 32 on the cog wheel 22 to bring said pawl out of engagement with the gear rim 32.
  • the pawl 31 is pivotally mounted on the mounting block 16 and its function appears from Figs. 5 and 6, which show the ratchet mechanism in a view from theside with the shoe-support plate 1, the racks 11 and 12 and the shaft 14 and the angular arm 30 associated therewith.
  • Fig.5 shows the shoe-support plate 1 in support position with the ratchet mechanism in the non-operative (release) position. Through the action of the a draw spring the pawl arm 31 is urged into engagement with the outer gear rim 32 by means of a toothed segment formed on the pawl.
  • the free wheel 24 is arranged to run freely when the support plate 1 is pivoted upwards. This pivotal movement therefore will result only in release of the ratchet mechanism.
  • the free wheel 24 will block movements of the shaft 14 relative to the cog wheel 22 and rotation of the latter will result in displacement of the mounting block 16 relative to the racks 11 and 12.
  • the operating lever 28 assumes its upper blocking position, as illustrated in Fig. 4, pivotal movement downwards of the support plate 1 will bring the pole abutment member 2 closer to the gripping arm 4.
  • the gradual narrowing-down of the spacing between the abutment member 2 and the gripping arm 4 may continue until the inner gear rim 27 reaches the forward end piece 13 of the racks, shown in Fig. 7.
  • the movements described occur when the linesman is climbing upwards along a pole.
  • the climbing iron in accordance with the invention is also provided with a locking means 36 by means of which it is possible to block the shoe-support plate 1 relative to the support arm 15.
  • a locking means 36 by means of which it is possible to block the shoe-support plate 1 relative to the support arm 15.
  • the locking means may be used in the following manner: after having climbed a slightly conical pole over some distance with the shoe--support plate in blocked position, the user releases the locking means 36, thus adjusting the spacing between the abutment member 2 and the gripping arm 4.
  • the climbing iron in accordance with the invention may be used in connection with all types of wooden or concrete poles, irrespecitve of the conicity of the latter.
  • the manner of climbing poles with the aid of climbing irons in accordance with the invention is not essentially distinguished from that used with conventional climbing irons.
  • it is necessary that the foot is tipped at a steeper angle forwards in order to releave the load on the abutment member and the gripping arm, thus allowing them to slide along the pole surface.
  • the teeth of the racks 11 and 12 could face away instead of towards one another.
  • the teeth could be directed horizontally instead of vertically.
  • the abutment member 2 and the gripping arm 4 could be differently designed and be provided with hard-metal spikes to improve the frictional grip on poles of wood or on ice-covered poles (in the winter).
  • the ratchet mechanism 5 may be constructed with e.g. one gear rim which is common to the racks and to the ratchet mechanism.
  • the locking device 36 is not essential to the functioning of the inventive object but increases the usefulness of the climbing iron.
