Definitions

  • the present invention relates to a device intended to permit the transport of material up and down along a guide, said device consisting of a frame operated by a power plant together with bearing devices between the frame and the guide.
  • a problem is frequently encountered in conjunction with the design of a device for transporting the pipes and planks required for the erection of scaffolding. It is usual for scaffolding, which consists of vertical pipes and horizontal connecting pipes, to be erected without the help of a hoist.
  • the present.invention relates to a device intended for the transport of material up and down along a guide of such a nature that it has succeeded in solving the problems referred to above, said device consisting of a frame operated by a power plant together with bearing devices or bearing surfaces between the frame and the guide.
  • the present invention proposes that the frame shall exhibit at its lower end a first set of attachment arrangements intended to operate in conjunction with an attachment arrangement located in a support area for the load, and at its upper end a second set of attachment arrangements intended to operate in conjunction with one end of a supporting arm of which the other end carries an attachment arrangement intended for suspended loads.
  • the first- attachment arrangement may be in the form of holes passing through a hollow metal section, with sockets (of hollow metal.section) located in the support area also having holes, said sockets being so dimensioned as to fit inside or over the hollow metal section on the frame, and that a pin may be inserted through both the holes in the hollow metal section and the holes in the sockets.
  • the second attachment arrangement is in the form of a U-shaped groove with a hole extending vertically so that one end of the arm may be inserted into the U-shaped groove, said hole being fitted with a pin which acts as a shaft enabling the arm to pivot.
  • the attachment arrangement for suspended loads is in the form of a load hook, preferably attached to the other end of the arm so that it is free to rotate.
  • the upper end of the frame also has a third attachment arrangement intended to operate in conjunction with an attachment arrangement provided on a component forming an upward extension -of the frame.
  • the attachment arrangements formed on the component of the frame consist of holes through a length of hollow metal section, with sockets which form part of the component of the frame so dimensioned as to fit inside or over the length of hollow metal section on the frame and also provided with holes, and with a pin capable of being inserted through the holes.
  • the component of the frame is in the form of a frame with elements which may be folded up and down, and a control organ which is free to rotate is attached to the upper end of the component of the frame and is intended when folded down to serve mainly as a support for pipes and when folded up to permit the transport of planks resting against the support area.
  • the principal technical advantages which may be regarded as being associated with a device in accordance with the present invention are that the device has been designed in such a way that it may be converted by simple means from being used for the transport of material up and down along a guide re-sting on a support area to a device enabling the transport of material up and down suspended from an attachment arrangement.
  • Fig. 1 shows a device intended for the transport of material up and down along a guide.
  • the device consists of said guides 1 rigidly attached to a base plate 2 and secured partly by stays 3 and partly by clamps 4 attached to horizontal pipes 5 t forming part of a scaffolding 5 with vertical pipes 5" and with planks 7 arranged between the pipes 5' .
  • the pipes 5' and 5 11 are attached to each other by means of clamps 8.
  • the base 2 rests on the ground 9, as does the scaffolding 5 .
  • the guide 1 may best consist of a number of interconnected component parts enabling the guide 1 to be erected upwards or dismantled easily, depending on whether the height of the scaffolding is to be increased or decreased.
  • the device intended for the transport of material up and down along a guide consists of a frame 11 operated by a power plant 10 , of which the displacement is controlled by a cable 12 which runs from the power plant 10. upwards and over a guide pulley 13 and then downwards, as shown by the reference designation 12a , with the end of the cable which is not shown being attached to the upper part 11b of the frame 11 .
  • the frame 11 has at its lower end 11a a first attachment arrangement 130 as illustrated in Fig. 8 intended to operate in conjunction with an attachment arrangement 131 located in a support area 13 for a load.
  • a second attachment arrangement 14 as illustrated in Fig. 9 intended to operate in conjunction with one end of a supporting arm 15 , shown in Fig. 6, of which the other end carries an attachment arrangement 16 intended for suspended loads.
  • Fig. 8 indicates that the first attachment arrangement 130 consists of two holes 132 , each of which passes through a hollow metal section 17 attached to the frame .11 , and two holes 131 in two hollow sections 18 , said hollow metal sections being dimensioned so as to fit either inside or over each other, together with two pins, each pin 19 being capable of being inserted through both the hole 131 in the hollow metal section 18 and the hole 132 in the section 17 .
  • the support area 13 is fitted with upward-facing sides with the reference designations 13a,13b and 13c.
  • the second attachment arrangement 14 shown in Fig. 9, consists of a U-shaped groove 14a with a hole 14b which extends vertically, and one end 15a of the arm 15 which is also provided with a hole may be inserted into the U-shaped groove 14a .
  • a pin 20 passes through all the holes and acts as a shaft enabling the arm 15 to pivot. (The attachment of the arm is not shown in Fig. 9).
  • the attachment arrangement intended for suspended loads consists of a load hook 16 , preferably attached to the other end 15b of the arm so that it is free to rotate.
  • the pivoting shaft formed by the pin 20 enables the arm 15 to move to a variety of positions, with the solid arm shown in Fig. 6 illustrating the position used for the transport of material up and down along the guide 1 , whilst the arms shown with dotted lines in Fig. 6 illustrate the manner in which the load may be swung over so that it may be lowered onto planks 7 forming part of the scaffolding.
  • the upper end 11b of the frame also has a third attachment arrangement 21 intended to operate in conjunction with two attachment arrangements 23 formed on a component 22 forming an upward extension of the frame.
  • the attachment arrangements 23 provided on the component of the frame 22 consist of two holes, each of which passes through one of the hollow metal sections 24 , with sockets forming part of the component of the frame being so dimensioned as to fit either inside or over lengths of hollow metal section 25 on the upper end 11b of the frame.
  • Each length of hollow metal section 25 is provided with a hole 26 , and a pin 27 may be inserted into the holes 26 , 23 which operate in conjunction with each other.
  • the component of the frame 22 consists of a frame with three vertical.elements 28 , 29 and 30 and with horizontal elements 31 , 32 , 33 and 34 .
  • One frame element 35 is attached to the element 30 at point 35a in such a way that it is free to move and is provided with a locking arrangement so that it may adopt the position indicated in Fig. 1.
  • One frame element 36 is attached to the element 29 at point 36a in such a way that it is free to move and is so arranged that it may be locked in the position shown in Fig. 1.
  • frame elements 37 and 38 Frame elements 35 , 36 , 37 and 38 may be moved into a folded-up position.
  • Fig. 2 shows how the frame elements .36 and 38 have been moved to the folded-up position, thereby opening the component of the frame enabling a number of pipes 5" to rest against the support area 13 , and how they are held in position by a control organ 39 attached to the upper end 22b of the component of the frame 22 so that it is free to move.
  • the position of the control organ 39 in Fig. 2 shows that the pipes 5" may simply be positioned parallel to each other.
  • the control organ is free to move and is able to adopt the position shown in Fig. 1 or the position shown in Fig. 2.
  • Fig. 3 illustrates how the control organ 39 is able to.adopt an outward-facing position (similar to Fig. 1), enabling the planks 7 to be loaded and to rest against the support area 13 and a frame element 40 , at the same time as the frame elements 38 and 36 are in a folded-up position.
  • Fig. 4 shows that the support area 13 has been removed from the lowest part of the frame and that the component of the frame 22 has been removed from the upper part 11b of the frame 11 and that a supporting arm 15 has been attached to the second attachment arrangement 14 .
  • Fig. 4 shows a number of bricks 42 loaded on a trolley 41 suspended from the load hook 16 , representing a load -suspended from the attachment arrangement 16 .
  • Fig. 5 shows a wheelbarrow 43 filled with mortar representing a load suspended from the load hook 16 .
  • the arm 15 may be pivoted about one of its ends 15a and about the pivoting shaft 20 , enabling the wheelbarrow 43 to be swung across and positioned directly over the planks 7 supporting the person 44 .
  • Fig. 7 shows a section through a guide profile, from which section it may be seen that the dimensions of the flat surfaces should be 50 mm in a preferred embodiment.
  • the space 45 is intended for clamps or securing devices 4 between the guide 1 and the pipes 5' , whilst the channels 45a and 45b are intended to accommodate connecting unions between two adjacent guide elements.
  • the space 45c may also serve as a guide track and bearing surface for the frame 11 as this is displaced up and down along the guide.
