Definitions

  • the invention relates to a crane silo for the transport of pourable building materials, such as concrete, gravel, sand or the like., With a top loadable through a filling container, which has an openable by means of lever mechanism flap closure for emptying at the lower end and for parking on a frame is attached.
  • the US 2'713'507 A describes a concrete bucket for the transport of free-flowing building materials, with a container having evenly sloping sloping inner walls and a rectangular container bottom outlet with parallel longitudinal edges, wherein the outlet opening formed by a larger cross section than the cross section arranged above the container end and arranged below the bottom outlet a flap closure is.
  • the US 2,713,507 shows the subject of the preamble of claim 1.
  • the object of the present invention is to provide suitable functionality and a relatively low weight with optimum absorption capacity. That is, it is to create a crane silo, which has in unfavorable environmental conditions, when it is to be operated by a person, for example, from narrow booths, a high ease of use and excellent functional insert properties.
  • This goal can be achieved by the container shell at its height from a circular feed opening into an approximately oval or elliptical Outlet opening is progressively deformed, so that a large outlet opening can arise on the container.
  • angular edges are to be avoided, which would not least be stressed by the mass to be emptied, with a high coefficient of friction acting on the outlet opening to heavy wear on the container inner wall ,
  • the outlet opening resp. Edge adapted to the rectangular outlet opening of the flap closure, formed with rounded edges.
  • the outlet opening of the container should have, according to the movement of the flap bottom, at least approximately straight intermediate sections on the longitudinal and / or narrow side.
  • An excellent outlet opening of the container can be achieved if the transition from the longitudinal to the narrow side of the outlet opening is in each case designed as a curved section, so that an optimal seal can be created by the flap closure at the outlet opening of the container 3.
  • the jacket plate thickness of the container 1.25 to 1.75 mm, preferably 1.5 mm, which contributes to the optimization against wear, for a high reliability and a favorable dead weight and allows the use of commercially available metal sheet.
  • the container may be provided on the outer circumference with a reinforcing ring between the feed and outlet opening, which is able to absorb the relatively high Leibungstik without noticeable self-weight gain.
  • the filling opening of the container is formed by a bead-like edge damage can be avoided when hitting the crane silo on solid objects and the container greater rigidity and stability can be taught.
  • the bead-like edge may be formed in a simple manner by a pipe connected to the container jacket by welding.
  • the jacket parts are welded to form a container, it is favorable if the former have overlapping tabs along at least one edge region along a jacket part.
  • the partially double-wall forming flaps may be formed at the upper end of the container for attachment of a suspension of the silo, for example by suspension eyes. If above the outlet opening of the container at the periphery of a sleeve is applied by welding, then this can help the stability of the container beyond this range.
  • the outlet opening of the container forms a sealing lip opposite the flap closure, which will simultaneously serve as a reinforcement of the edge region against wear.
  • the flap closure with arranged on the frame by means of operating lever (s) operable lever drives drive connected, the one resp. facilitates the operability of the flap closure due to reduction ratios.
  • the frame to which the container is attached viewed in plan view, preferably has a rectangular shape whose longitudinal side extends approximately parallel to the pivot axis of two flap closure elements forming the flap closure; that is, the container is protected at its height against impact damage, on the one hand by the bead-like upper edge of the filling opening and on the other hand by the frame below. Nevertheless, the frame does not survive the container laterally.
  • a shaft is provided for actuating the two flap closure elements at the lateral ends of the flap closure along the longitudinal side of the frame and this twice stored, which the lever mechanism combines.
  • the operation of the flap closure is suitably set so that the flap closure elements for opening against a closing force can be pivoted, whereby the amount of building material to be taken is easily metered.
  • displaceable chute be attached to the frame which is attached to pivotable about a horizontal axis arms and from an upright operating position side of the container in a sloping operating position is pivotally.
  • the Fig. 1 to 4 show a crane silo 1 for the transport of pourable building materials such as concrete, gravel, sand or the like.
  • container 3 which has a lever mechanism 31, 32 openable flap closure 4 for emptying at the lower end and is attached to a rack 5 for parking on the ground or a scaffold, etc.
  • the container 3 has a circular filling opening 2, to which a container casing 6 adjoins and ends at the lower container end with an approximately oval or elliptical outlet opening 7.
  • a circular outlet opening would have the consequence that, on the one hand, the emptying opening of the flap closure could not be optimally utilized and, on the other hand, a rectangular outlet opening would have insufficient strength.
  • the outlet opening is designed deviating from a circular or rectangular shape, such that it probably comes closest to an oval or an ellipse.
  • this does not mean that the outlet opening 7 considered in plan view has a pure oval or elliptical shape, in order to meet the invention.
  • a circular curved steel tube 8 which is welded to the container shell 6.
  • Fig. 2 shows from the bird's eye an outlet opening 7 of the container 3 on the longitudinal and the narrow side formed by at least approximately straight intermediate sections 9, 10 which are part of a rectangular shape. Both sections 9, 10 can also be canceled by irregular curvatures, so that the outlet opening 7 is similar to an Elipse.
  • the illustrated generatrices of the container shell 6 are outwardly acting edges 11 which stiffen the container shell 6; The arrangement of the edges 11 and the course lead to the apparent outlet opening 7.
  • the funnel-shaped container 3 could also have a frustoconical jacket without edges.
  • the container casing 6 has due to the outlet opening 7 on different levels of generatrices on the circumference, which, however, do not deviate more than 15 ° from a vertical.
  • the wall thickness of the container 3 is 1.25 to 1.75 mm, preferably 1.5 mm, with corresponding differences in the design of a lightweight crane silo correspondingly noticeable.
  • the at the filling opening 2 a bead-like edge forming steel tube 8 is welded to the container shell 6, preferably so that the weld seam passes smoothly to the inner or outer circumferential surface of the steel tube 8.
  • the container casing 6 consists of two at least approximately uniform shell parts 12, 13, which are subsequently formed on a surface line in an edge region by a tab 54, which is welded overlapping with the edge region of the abutting shell part 13, 12.
  • the outlet opening 7 is attached to the container 3 enclosing this cuff 18, preferably welded to the container shell 6.
  • the sleeve 18 is at the lower end, at least in partial areas on the circumference, designed by a vertical portion 19, which gives the expiring materials in the edge region a vertical direction of movement, ie, that the container 3 in front of the outlet opening 7 has a vertical portion which at the decisive container shape, however, does not change anything.
  • the sleeve 18 is formed to stiffen the wall on these longer sections cramped outwards (see Fig. 6 ).
  • the outlet opening 7, whether with or without a vertical outlet section 19 on the sleeve 18, has at its lower end a sealing lip 20 acting opposite the flap closure 4.
  • the flap closure 4 consists of two oppositely pivotable, cooperating flap closure elements 21, 22, each one after the Swivel radius bent bottom plate 23, 24 which move along the sealing lip 20 when opening and closing the flap closure 4.
  • the flap closure 4 and the flap closure elements 21, 22 are each mounted on opposite transverse struts 25, 26 of the rectangular frame 5 viewed in plan view about a horizontal axis 27, 28 pivotally.
  • lever-like drive elements 29, 30 are provided on the flap closure elements 21, 22, which are drive-connected to a respective lever mechanism 31, 32.
  • lever mechanisms 31, 32 which are each associated with a lateral flap closure end, have two-armed (extended) levers 33, 34 which are fastened to a shaft 35 and whose lever arms 38, 39 are each connected to a handlebar 36, 37 with the flap closure elements 21, 22 are connected.
  • the shaft in turn is mounted at the longitudinal ends of the frame 5 in bearing blocks 40 and has both ends a fixedly arranged operating lever 41, with which the flap closure 4 can be opened and closed.
  • the longitudinal sides of the frame 5 run at least approximately parallel to the pivot axis of the flap closure 4. The opening of the flap closure 4 takes place against a closing force, to which a spring 53 connected to the two-armed (extended) lever 33, 34 and the frame 5 is arranged.
  • the lever mechanism 31, 32 are protected by a housing 42 against external influences.
  • the crane silo 1 is provided with a displaceable below the discharge opening of the flap closure 4 in an operating position discharge chute 43 which is attached to pivotable about a horizontal axis arms 44, 45 and from an upright operating position next to the container 3 -wie in the Fig. 1 and 4 shown in a sloping operating position is pivotable.
  • a gas spring 55 is provided in each case, with the ends on the one hand attached to the frame 5 and on the other hand connected to an arm 44, 45, such that the outlet chute 43 is held in a pivoting movement of the gas spring 55 in the operating position.
