Definitions

  • the present invention relates to a system and apparatus for moving objects.
  • a Tyrolean traverse is performed by connecting a main line between two remote locations, and placing a carriage on the main line.
  • the carriage has a plurality of sheaves or other low-friction devices that allow it to travel along the main line.
  • Control lines are connected to the carriage to control its movement along the main line.
  • the carriage also has connection points to which a load can be connected. As the control lines are used to move the carriage along the main line, it is possible to move a load connected to the carriage between the remote locations.
  • This arrangement has a variety of applications, including movement of inanimate objects, such as timber from a cut-down tree, or transport of people, either to cross a void, or to rescue an incapacitated person.
  • the present invention provides a trolley for lifting and/or moving a load on one or more lines comprising:
  • lines can be introduced into or removed from a space between the plates to come into contact with the fixed sheaves. Once the removable sheave components are connected to the plates, such lines can make rolling contact with the sheaves and sheave components, but cannot be removed from between the plates (other than by allowing an end of the line to pass between the plates).
  • a typical trolley includes two or more removable sheave components.
  • One or more of the removable sheave components may be constituted by a pulley wheel that is part of a pulley assembly that includes the shaft.
  • the pulley assembly typically includes a body upon or within which the pulley wheel is carried for rotation. Most typically, in such cases, part of the body is disposed between the plates to enable it to be connected to the plates.
  • the body may have an eye, and securing pin may be passed through the eye and apertures in the plates to secure the body to the plates.
  • one or more sheave component typically rotates about a respective axis that is adjacent to the plates and one or more sheave component may be wholly or partly external to the plates.
  • One or more of the removable sheave components may be constituted by a sheave that includes a rim that is carried on a hub.
  • the hub typically includes a bearing to permit free rotation of the rim about an axis passing through the hub.
  • the sheave may be connected to the plates for use by a removable securing pin that passes through the hub and through apertures in the plates to secure the hub to the plates and to constitute the shaft about which the sheave component rotates.
  • the pin is typically centred on the axis of rotation of the rim.
  • one or more sheave component typically rotates about a respective axis that passes through the plates and one or more sheave component may be wholly or partly disposed between the plates.
  • each plate includes a void that is constituted by a recess formed into an edge of the plate.
  • the void can receive a device for connection with a load, such as a pulley, when the trolley is in use, which helps to reduce the extent to which a load suspended from the trolley can swing when it is being moved.
  • this invention provides an installation for lifting and/or moving a load that includes a trolley embodying the first aspect of the invention, a main line that extends between two fixed anchorages, and which, in use, passes between the plates of the trolley, whereby the main line makes contact with one or more sheave or sheave component of the trolley whereby the trolley can be suspended from and travel along the main line; and a control line that is connected to the trolley whereby the trolley can be drawn along the main line.
  • a typical installation further includes a lifting line that passes between the plates of the trolley and over two or more sheaves or sheave components of the trolley, the lifting line carrying, between the sheaves or sheave components, a device such as a pulley for connection with a load.
  • this invention provides a method of installing an installation according to the second aspect of the invention comprising:
  • a basic assembly being part of apparatus for moving objects comprises similar first and second planar metal plates 10, 12.
  • Each plate 10, 12 is symmetrical about a median plane M.
  • the plates 10, 12 are parallel and spaced in a direction normal to the plane of each plate.
  • the surfaces of each plate 10, 12 that face one another will be referred to as the inner surfaces and the opposite surfaces, which face away from one another will be referred to as the outer surfaces.
  • the peripheries of the plates 10, 12 are coincident when projected in a direction normal to their planes.
  • Each plate 10, 12 is shaped generally as an inverted "U", with two leg regions interconnected by a bridge region, the bridge region extending across the median plane M.
  • a plurality of apertures extend through the plates 10, 12, the similarity and symmetry of the plates meaning that each aperture in the first plate 10 is paired with and aligned with a corresponding aperture in the second plate 12.
  • a void 14 is defined between the leg regions, the void 14 being a recess that extends from an edge of the plate 10, 12.
  • Each leg region includes a circular sheave axle aperture 20 (making a total of four sheave axle apertures 20, two in each plate, each having a corresponding paired aperture in the other plate).
  • a sheave axle is carried by each pair of sheave axle apertures 20.
  • the sheave axle has a head 22 from which a shaft 24 extends.
  • the shaft 24 is a close fit within the sheave axle apertures 20 and passes through both of the sheave axle apertures 20 in the pair.
  • the head 22 is of a size that it cannot pass through the sheave axle aperture 20 and is in abutment with the outer surface of the first plate 10.
  • a threaded spigot 28 extends from the shaft 24 to project beyond the outer surface of the second plate 12.
  • a nut 26 is applied to the spigot and tightened against the outer surface of the second plate 12 to retain the sheave axle in place and to substantially prevent any movement of the sheave axle within its apertures.
  • Each sheave axle carries a respective fixed sheave 30 upon its shaft 24 between the plates 10, 12.
  • Each sheave 30 includes a rope-bearing rim 32 with a central hub within which a rolling-element bearing 34 is contained, an inner race of the rolling element bearing 34 being carried on the shaft 24 whereby the sheave 30 can rotate about an axis normal to the plates 10, 12.
  • the sheave 30 is selected to be of width such that there is minimal clearance between it and each plate 10, 12.
  • the sheave axle apertures 20 are positioned such that the sheaves 30 closely approach but do not enter into the void 14.
  • a plate joiner aperture 40 is formed through each leg region.
  • Each plate joiner aperture 40 is formed as an arcuate slot that is centred approximately on the nearby sheave axle aperture 20.
  • a plate joiner is carried by each pair of plate joiner apertures 40.
  • the plate joiner has a head 42 from which a shaft 44 extends. The head 42 is of a size that it cannot pass through the plate joiner aperture 40 and is in abutment with the outer surface of the first plate 10.
  • a threaded spigot 50 extends from the shaft 44 to project beyond the outer surface of the second plate 12.
  • a nut 46 is applied to the spigot 50 and tightened against the shaft 44 such that it is not tight against the second plate 12. The nut 46 retains the plate joiner in place while allowing it to slide along the arcuate length of the plate joiner apertures 40.
  • the basic assembly described so far is a permanent or semi-permanent assembly - that is to say, its components are assembled during manufacture and are subsequently disassemble (if at all) only during a repair procedure and not when the apparatus is in use.
  • Each securing pin 46 has a head from which a cylindrical shaft extends.
  • a plurality of projections extend radially from the shaft in a locking condition (the normal state of the securing pins).
  • a control button on the head can be depressed to cause or to allow withdrawal of the projections into the shaft.
  • Each securing pin 46 cooperates with a pair of circular apertures through which the shaft is a close sliding fit. When the securing pin 46 is manually grasped by its head and the control button is depressed, the shaft can slide freely within the apertures.
  • the securing pins 46 are chosen to have a length that is slightly greater than the distance between the outer surfaces of the plates 10, 12, such that when inserted through a pair of apertures, while in the locking condition minimal axial movement is possible. Simpler fasteners, such as nuts and bolts may provide an alternative to the quick-release pins.
  • the apparatus further includes a plurality of pulleys 48, which are also of conventional design, and many readily available pulleys are suitable for use. These constitute removable sheaves.
  • the significant features of a suitable pulley is that it has a pulley wheel carried for free rotation between plates, and that there is an eye extending through the plates parallel to the axis of rotation of the pulley wheel.
  • the pulleys must also be dimensioned to operate properly with the lines to be used. It is preferable, but not essential, that the pulleys are of a type that can be installed on a line without the requirement to feed an end of the line through the pulley - for example, it may have plates that can be mutually rotated to an open position allow it to be installed upon a line.
  • an installation for performing a Tyrolean traverse includes several lines of rope or cable.
  • a main line 60 is fixed when the installation is in use and extends between fixed locations at opposite ends of a space to be traversed.
  • a lifting line 62 also spans the space to be traversed, but can be lengthened or shortened at one or both of its ends, for example by being secured to a winch.
  • a control line 64 extends from one end of the traverse to the trolley.
  • An object to be moved (not shown) is carried on a load line 66 which is secured to the eye of the lifting pulley 48C.
  • the height of the load can be controlled by shortening or lengthening the lifting line 62 to raise or lower the load, respectively.
  • the position of the trolley on the main line 60 can be controlled by drawing in or letting out the control line 64. Shortening of the lifting line 62 causes the lifting pulley 48C to rise from a lowered position, as shown in Figure 11 , until it enters into the void 14 within the plates 10, 12, as shown in Figure 12 . This minimises the amount by which the load hanging from the lifting pulley 48C can swing as it travels along the main line 60.
  • a single control line 64 will suffice, as shown in Figure 3 , the trolley being pulled in one direction along the main line 60 using the control line, and returning in the opposite direction under the influence of gravity.
  • a second control line 68 is shown, which allows the trolley to be pulled in either direction on the main line 60. This could be connected directly opposite the first control line 64, or alternatively, as shown in Figure 11 , to a securing pin 46 inserted through apertures 74 located further from the main line 60.
  • the opeanble pulleys 48 described above are replaced with pulleys 80 that have a fixed frame that cannot be opened, as shown in Figure 13 .
  • the sequence of assembling the installation described above must be varied to ensure that the suspension pulleys 80A, 80B and the lifting pulley 80C are installed on their respective lines 60, 62 before the ends of the lines are secured. The construction and operation is otherwise as described above.
  • suspension pulleys 48A, 48B are replaced by removable sheaves 86A, 86B, as shown in Fig 14 .
  • Each sheave 86 comprises a rope-engaging rim 88 carried on a roller bearing 90, as shown in Figure 15 .
  • Each sheave is carried on the shaft of a respective securing pin 46 that is passed through the locating apertures 70.
  • securing pins 46 may be inserted into apertures even if no external component is to be connected, for example as shown in Figures 11 , 13 and 16 . This can help to prevent the plates 10, 12 spreading.
  • a tubular cylindrical spacer (92) may be carried on the shaft of one or more securing pin 46A to prevent the space between plates 10, 12 from closing. In this example, a spacer is installed using apertures 76 at the centre of the bridge region.
