Definitions

  • the invention relates to connecting rods between the load hook and the elevator of a drill pipe with eyes provided at each end of the rod.
  • Such connecting rods are used in pairs on the load hooks in drilling towers for suspending the "elevators” as so-called “elevator brackets”.
  • the connecting rods are subject to severe wear, which mainly occurs in the eye area. This damage can be remedied by grinding out and build-up welding and tempering the connecting rods again, however a reduction in lifting capacity may be unavoidable. If there are major signs of wear, the connecting rods must be scrapped for safety reasons.
  • the previously known connecting rods are made in one piece in a cast or Sch deie construction or from a combination of both manufacturing processes
  • the invention has for its object to reduce the amount of connecting rods to be stored as spare parts.
  • the couplings can be designed using joints, threads, clamps, bolts, brackets, etc.
  • the stock of the reserve rods can additionally be reduced if the load hook eye is also interchangeably attached to the shaft. Worn load hook and elevator eyes are then easily exchangeable.
  • the connecting rods By dividing the connecting rods into several parts, different materials can be used. For example, the cast iron or the eyes and the shaft is made of rolled material. This will reduce! the manufacturing cost. If the hook eye is not to be coupled to the shaft, a welded connection is also conceivable.
  • damping devices can be provided in the connecting rods via, for example, Fer hydraulics, which enable a reduction in the shock effect when the load is taken up, as a result of which it is conceivable to use inexpensive, ie undamped load hook types.
  • Fer hydraulics which enable a reduction in the shock effect when the load is taken up, as a result of which it is conceivable to use inexpensive, ie undamped load hook types.
  • FIG. 1 shows an elevator 5 of a drill rod, also not shown, suspended on the load hook 4 of a hoist (not shown) with the aid of connecting rods 3.
  • Each of the connecting rods 3 consists of two flat iron strips 6, which are detachably connected to the upper hook eye 1 and the lower elevator eye 2 by means of a bolt, screw or plug connection 16.
  • Fig. 2 shows between the load hook 4 and the elevator 5 i
  • Attachment to the eyes 1 'and 2' consists of a bolt, screw or plug connection 17.
  • 3 shows connecting rods 3 "in rod shape 9.
  • the detachable connection with eyes 1" and 2 " is shown using the example of the elevator eye 2" in FIGS. 3a to 3e and the example of the lifting hook eye 1 "in FIG. 3f.
  • Fig. 3c shows two cuts perpendicular to each other through a two-part, e.g. screws 12 (not shown) held in holes 11a of the flanges 11 coupling 12 Rectangular or round heads of the parts 2 "and 3" detachable and, if necessary, non-rotatably connected
  • 3d shows a detachable connection of the parts 2 "and 3" produced by flat overlaps 13 by means of screws 13a.
  • Fig. 3e shows a similar overlap '14 as shown in FIG. 3d, but with a shear surface 15 for relief of the bolt 14a in tension.
  • __c: 3f shows a connection of the parts 1 "and 3" by welding. This connection is released by a flame or saw cut along line 18 and the connection is restored by welding the machined cut surfaces of parts 1 "and 3" again.

Abstract

Entre le crochet de levage (4) et l'elevateur (5) d'un dispositif de levage d'une tige de forage sont interposees des tringles de liaison (3) presentant au moins des anneaux interchangeables (2) d'accrochage de l'elevateur. La liaison (16) entre les tringles et les anneaux de l'elevateur peut etre formee d'une liaison a cheville, a vis ou d'un accouplement a fiches. Dans ce cas les tringles de liaison (3) peuvent etre constituees chacune de deux barres de fer (6) ou d'un tuyau (7). On peut egalement utiliser des tiges (9) comme tringles, la liaison avec les anneaux d'accrochage de l'elevateur pouvant alors etre realisee a l'aide de coussinets, de brides, par chevauchement ou vissage. L'anneau d'accrochage (1) au crochet de levage peut aussi etre fixe aux tringles (3) de maniere amovible. De cette maniere il est possible d'echanger aisement les anneaux uses de l'elevateur et eventuellement aussi les anneaux d'accrochage au crochet de levage.
