Definitions

  • This invention relates to rigging components and locking pins therefor, for example, shackle assemblies and locking pins for locking the shackle pins in place in the shackles.
  • the invention has particular application to components for heavy lifting equipment as well as components for draglines such as drag links and lift cables, and components for other earthmoving and mining equipment, and accordingly reference will be made to such applications. While shackle assemblies in particular will be described it will be appreciated that the invention may have use in other applications. In particular some components may be used in applications without other components .
  • Shackle assemblies of the type to which the invention relates typically include a U-shaped shackle with two opposed legs defining a mouth and a shackle pin extending between the two legs and releasably engaged therewith to close the mouth.
  • the present invention is aimed at providing a shackle assembly and a locking pin for releasably locking the shackle pin in the engaged or operative position.
  • the invention is also aimed at providing a locking pin which can be used to lock pins other than shackle pins in an operative position.

  • said locking member being adapted for engagement in a recess in said one leg upon being expanded so as to secure said shank in said locking pin passage.
  • said locking pin includes forcing means for forcing the locking member outwards into engagement in the recess.
  • the forcing means includes a plate or a washer or similar device which cooperates with the upper face of the locking pin head to crush the locking member therebetween in the direction of the longitudinal axis of the locking pin so as to force it to expand laterally.
  • the forcing means be arranged to selectively maintain a crushing force on the locking member and that the locking member be formed of a resilient material adapted to contract upon the crushing force being removed.
  • the forcing means includes a bolt arranged to screwthreadedly engage in a complementary screwthreaded bore in the pin head and/or the shank of the locking pin such that upon screwing the bolt into the bore a force is applied to the locking member to force it to expand laterally.

  • a shackle pin 17 is slidably mounted in the passages 14 and 16 for securing the shackle assembly to a cable or other rigging component.
  • the shackle pin 17 is secured in the shackle pin passages by a locking pin 18 which is fitted into locking pin passage 15 provided in shackle leg 13 as will be described in more detail later.
  • the shackle pin 17 has a generally cylindrical head 19 at one end having opposed flat side faces 21 and 22 which are arranged to engage with complementary flat faces 23 and 24 at the outer entry to shackle pin passage 14, and a semi-cylindrical slot 26 that resembles a keyway extending laterally across the shank 17 near the other end of the pin.
  • the locking pin or locking pin assembly 18 has an elongate shank 31 of constant generally "D" shaped cross section with a semi-cylindrical portion 32 contiguous with a rectangular portion 33 having three flat sides 34, 35 and 36 with a longitudinal axis 37.
  • the shank has a cylindrical head 38 at one end coaxial with the longitudinal axis while the other end is free.
  • a cylindrical recess 39 is formed centrally in the head 38 coaxial with the longitudinal axis 37 of the pin for receiving therein the spigot of a spigot washer as will be described later and a threaded bore 40 contiguous with the recess extends further into the head and is coaxial with the longitudinal axis 37 for receiving a bolt as will also be described later.
  • the locking pin includes a washer assembly 41 which is mounted to the outer face of the head 38 and is secured thereto by a hex flanged bolt 42 having a hex head 43, a flange 44 and a threaded shank 45 adapted to screw into threaded bore 46 in the pin head 41.
  • the washer assembly includes a metal spigot washer 47 with a flat rubber washer 48 mounted on the spigot 49 and as can be seen in Fig. 6, the bolt flange 44 is adapted to engage the outer face of the spigot washer.
  • FIG. 5 shows the locking pin mounted in a cup shaped insert 51, the insert is fitted into a complementary recess formed in the leg 13 and welded therein before the locking pin is fitted to the insert.
  • Figs. 5 and 6 show the insert removed from the shackle leg and the pin fitted thereto only for clarity.
  • the insert is generally frustoconical in form with a tapered side wall 52 and a bottom or inner wall 53 having a generally D shaped hole therethrough coaxial with the longitudinal axis 37 of the locking pin shank 31.
  • an annular recess 56 is provided in the wall 52 of the insert of generally semi-circular cross section as can be seen in Figs. 8 and 10 for a purpose which will be described later.
  • a locking pin passage 61 extends through shackle leg 13 orthogonal to aligned shackle pin passages 14 and 16 and partly intersects the shackle pin passage 16 through its upper portion so that it can fully engage the slot 26 in the shackle pin 17. It will be appreciated that the flat sides 34 and 36 engage the opposed lateral faces defining the slot 26 while flat 35 engages the flat side 55 defining one side of hole 54 thereby providing an increased area of contact over a round pin and preventing rotation of the locking pin in the locking pin passage 61.
  • the locking pin 18 is inserted into the locking pin passage 61 through the D shaped hole 54 in the insert and through the slot 26 in the shackle pin to lock the shackle pin in the closed or engaged position as shown in Fig. 1 and once so positioned, the locking pin itself is locked into position by tightening the bolt 42 in the threaded bore 46 so as to force the spigot washer to squeeze the rubber washer 48 between the spigot washer and the upper face of the locking pin head 38 causing it to expand radially outwards. As can be seen in Figs. 8 and 10, radial expansion of the rubber washer causes it to engage in the annular recess 56 in the insert thereby securing the locking pin in the locking pin passage.
  • the locking pin 18 can be removed by simply unscrewing the bolt 42 and allowing the rubber to shrink radially or by removing the bolt 42 and the spigot washer 47 and then levering the rubber washer out of the insert whereupon the locking pin can be removed. In some cases, the pin can be driven against the rubber washer to remove it once the bolt 42 has been removed.
  • the locking pin assembly 118 illustrated in Fig. 19 is similar to the locking pin assembly 18 illustrated in Fig. 5 with the insert 52 assembled therewith for explanatory purposes only. In that respect, the insert is fitted to the shackle and welded therein and the locking pin is then also fitted to the shackle and locks to the insert.
  • the same reference numbers are used herein to refer to corresponding components or features where possible except prefaced by a "1". Further, where corresponding components or features have been referenced with such corresponding numbers but are not specifically described such features can generally be assumed to have the same function .
  • the locking pin includes a washer assembly 141 which carries out the same function as washer assembly 41 but in a slightly different manner.
  • flexible and resilient flat washer 148 is mounted on the spigot 149 of spigot washer 147 prior to assembly and then it becomes largely mounted on the spigot portion 150 of the locking pin head 138.
  • the arrangement allows for a greater length of thread to be provided in the head and shank 131 for the bolt 142 while at the same time providing further protection for the head of bolt 142 in the cup 147a formed by the insert 147.
  • cup wall 147b of the spigot washer provides a significantly stronger washer for engaging with the outer face of the flexible washer whereby a greater force can be applied by bolt 142 without detrimental deformation.
  • recess 156 is substantially rectangular in cross section rather than substantially semicircular as in the case of recess 56 thereby allowing the flexible and resilient washer 148 more space to retract to a lesser diameter when the force applied by bolt 142 is removed by removal of the bolt. Further, as can be seen more clearly in Fig.
