Definitions

  • the present invention relates to a chassis with support arm on the ground for a hoist, in particular for a tower crane. Still more particularly, this invention is concerned with a frame provided with a plurality of ground support arms, generally four like-to-one support arms, articulated about vertical axes on a fixed central structure of this chassis. The invention is more specifically focused on achieving the articulated connection between each support arm on the ground and the fixed central structure of the frame.
  • the most common ground support system consists of several support arms, usually four support arms, articulated to the central structure of the frame around vertical axes, and thus made deployable for the use of the crane and foldable against the central structure to allow the transport of the crane in a minimum footprint.
  • the patent French FR 1494349 illustrates such a tower crane fixed frame provided with two folding support arms.
  • the patent French FR 2846955 or its equivalent the patent application European EP 1418151 A , describes a tower crane fixed frame with four folding support arms.
  • the articulation device of a support arm on the central structure of the frame, about a vertical axis is here of the clevis-tenon type: the clevis is constituted by an angle of one upper horizontal sheet and a lower horizontal sheet of the central structure of the frame, and the pin, taking place between these two superposed sheets, is constituted by an end of the support arm.
  • the connection between the support arm and the central structure of the frame comprises a massive hinge pin with enlarged lower head, the head being positioned at the bottom plate of the central structure of the frame.
  • the current devices for articulating a support arm to the central structure of the frame are specific to each support arm, and must in particular be adapted to its height. , especially with regard to the dimensioning of the hinge axis.
  • the present invention aims to avoid all of the previously mentioned disadvantages, and is therefore intended to facilitate the mounting of the frame and in particular the support arms, eliminating the need for the flipping of the frame and a precise alignment of the arms while limiting the bracing phenomena, the proposed solution also creating a connection of the support arms with the central structure of the frame which is, without modification, usable for support arms of different heights , with a view to streamlining manufacturing.
  • each support arm is equipped with a lower end which comprises a connecting plate with the rest of the support arm, and a trunnion protruding under the lower face. of the connecting plate
  • the upper part of each support arm is equipped with an upper end which comprises a connecting plate with the rest of the support arm, and a trunnion projecting on the upper face of the plate link.
  • each support arm has a cleat secured to the connecting plate and eccentric relative to the upper journal, the cleat being provided to abut under the upper half-clevis in the extended working position of the support arm.
  • the cleat thus allows, in the working position, to completely eliminate the undesirable phenomenon of bracing, transmitting the shear force to the central structure of the frame.
  • These bores can be three in number, thus providing a choice immobilization of the support arm in the extended working position, or in the folded transport position, or in an intermediate position of mounting.
  • the upper half-clevis may be pierced with fixing holes, provided for the removable attachment, by means of screws, the bearing plate with cylindrical bore.
  • Figure 1 shows the fixed frame of a tower crane, which is composed of a central structure 2 and four support arms 3, deployable in a cross for the working position of the crane, and foldable against the central structure 2 for the transport of the crane.
  • the central structure 2 of generally square shape, comprises a lower horizontal plate 4 and an upper horizontal plate 5, connected by vertical welded walls 6.
  • a hinge device 7, of circular shape, is provided in the central zone of the structure 2, for mounting a crown and a rotating frame (not shown) above which usually rises the mast of the crane, which itself carries the boom of the crane.
  • Each support arm 3, itself consisting of welded sheets is articulated at one end about a vertical virtual axis 8 to the central structure 2 of the frame, in one of the four corner regions of this central structure 2
  • the other end of the support arm 3 carries an adjustable foot 9 of support to the ground.
  • each support arm 3 on the central structure 2 is particularly visible in Figure 2 and also shown in more detail in Figures 3 to 5, which is referred to below.
  • This articulation device comprises, inter alia, a lower nozzle 10 shown alone in FIG. 4, which takes place substantially in the horizontal plane of the lower plate 11 of the support arm 3.
  • the lower end 10 comprises a plate 12 connecting with the rest of the support arm 3, the plate 12 having a trunnion 13 of relatively large diameter normally projecting under its lower face ( Figure 3 showing the lower end 10 in the inverted position) .
  • the connecting plate 12 is also provided with a bore 14 of relatively small diameter, eccentric with respect to the axis of the pin 13. This connecting plate 12 is welded to the lower plate 11 of the support arm 3, as well as 'to its side plates.
  • the hinge device also comprises an upper nozzle 15, shown alone in FIG. 5, which takes place substantially in the horizontal plane of the upper plate 16 of the support arm 3, above the mouthpiece lower 10.
  • the upper end 15 comprises a plate 17 connecting with the rest of the support arm 3, the plate 17 having a trunnion 18 of relatively large diameter, coaxial with the trunnion 13 of the lower end piece 10 and protruding on the upper face of the plate 17.
  • the upper end piece 15 further comprises a cleat 19 of square or rectangular section, integral with the plate 17 and eccentric with respect to the axis of the trunnion 18.
  • the connecting plate 17 is welded to the upper plate 16 of the support arm 3 and to its side plates.
  • the hinge device On the side of the central structure 2 of the frame, and for each support arm 3, the hinge device comprises a lower half-yoke 20, constituted by the corresponding angle zone of the bottom plate 4 of said central structure 2
  • the lower half-clevis 20 is pierced with a cylindrical bore 21 of relatively large diameter, corresponding to the diameter of the pin 13 of the lower nozzle 10.
  • This lower half-yoke 20 is also pierced with three bores 22, 23 and 24 relatively small diameter, arranged on the same circle centered on the axis of the cylindrical bore 21 mentioned above.
  • the hinge device further comprises an upper half-yoke 25, of truncated shape, which is pierced with a cylindrical half-bore 26 relatively large diameter, corresponding to the diameter of the pin 18 of the upper nozzle 15.
  • the upper half-yoke 25 is also pierced with two fixing holes 27 for a support plate (see below).
  • the upper half-clevis 25 is completed by a support plate 28, pierced with a cylindrical bore 29 of relatively large diameter which forms the complement of the half-bore 26. Two screws 30 are provided for the attachment of the plate. support 28 on the corresponding upper half-cleft 25, through the holes 27 above.
  • the hinge device comprises a removable pin 31, of diameter corresponding to that of the bores 14, 22, 23 and 24, provided for the immobilization in position of the support arm 3 (see Figures 1 and 2).
  • the support arm 3 is first placed parallel to one of the sides of the central structure 2 of the frame, initially devoid of its support plates 28 so as to disengage all the upper half-covers 25.
  • the support arm 3 is then lowered to introduce the lower pin 13 of its lower pin 10 into the bore 21 of the lower half-clevis 20.
  • the upper pin 18 of the upper pin 15 is thus positioned in the half-bore 26 of the upper half-cap 25.
  • the same hinge device consisting of the two lower and upper ends 10 and 15, respectively, and the two half-yokes respectively lower and upper 25, the latter being completed by the plate support 28, can be used without modification for support arms 3 of different heights H. It is also understood that this hinge device is applicable to both support arms 3 of "monobloc" structure and therefore of invariable length, such as shown, that support arms of telescopic structure, in which case the device concerned serves for the articulated mounting of the rear element of each telescopic support arm.
