Definitions

• the invention relates to an articulated butt joint for suspension rails of monorails with vehicle wheels running on the lower flanges, in which connecting means are provided between the upper flanges, which serve to suspend the rails in the region of the rail joint and are guided in a circular arc so that they are a pivoting of the rails in the vertical longitudinal center plane to allow a joint in the area of the lower flanges and to transfer vertical and horizontal transverse forces from one rail end to the other, the joint in the area of the lower flanges being tensile in the longitudinal direction of the rail against vertical and horizontal transverse forces is, however, flexible.
• the connecting means consist in the region of the upper flanges
• connection between the lower flanges which is flexible against transverse forces, has the advantage that wear due to transverse forces in the area mm of the lower flange connection cannot occur, but assumes that the connection in the area of the upper flanges is designed such that they all Can absorb lateral forces, in particular the vertical transverse forces caused by the weight of the vehicles.
• the curved guide pin alone has to transmit the entire transverse forces caused by the vehicle weight.
• the impact forces which inevitably occur when crossing the impact gap act on the curved guide pin and its guidance via a relatively long lever arm.
• an articulated butt joint for suspension rails of monorail overhead conveyors is also known, in which below the lower flanges a bolt joint absorbing the transverse forces with an articulated bolt extending transversely to the longitudinal direction of the rail and between the upper parts flanges are provided one another in rail longitudinal direction überlap ⁇ pende Auf technicalbleche which are provided in the overlap- pungs Scheme with flared in the rail longitudinal direction elongated holes which serve for receiving an up • hang bolt.
• the connection formed in this way between the upper flanges has the disadvantage that it can only be used in combination with connecting means absorbing the transverse forces between the lower flanges. Otherwise there is a risk that if one of the rails bends in the vertical longitudinal plane, there will be a height offset between the abutting rails.
• the invention proposes, starting from an articulated butt connection according to the preamble of claim 1, that the connecting means between the upper flanges consist of suspension plates attached to the upper flanges, which overlap in the longitudinal direction of the rail and in the overlap area with overlapping elongated circular holes are provided, which serve to receive a suspension bolt, the center of the two arcs being in the middle of the joint gap and at the height of the running surfaces on the top of the lower flanges of the rails.
• the butt joint according to the invention initially has the advantage that both suspension brackets are connected directly to the suspension bolt, so that the transverse forces caused by the vehicle weight do not need to be transmitted from one rail end to the other. Rather, these transverse forces are transmitted directly from each rail end via the associated suspension plates
• the arrangement of the center points of the arcs of the elongated holes in the middle of the butt gap and at the height of the treads on the top of the lower flanges has the advantage that the butt gap to be traversed by the vehicle wheels is vertical in all possible angular positions of the rail Swivel plane remains minimally narrow and that the reaction forces generated by the embrasures of the two elongated holes are directed to the center of the gap at the height of the treads, * ie exactly to the point from which the impact forces generated when crossing the gap originate.
• a particularly preferred embodiment of the butt connection according to the invention provides that the suspension plates are arranged at one end of the rail on one side of the vertical longitudinal center plane of the rail and at the other end on the opposite side of the vertical longitudinal center plane of the rail .
• the rails at both ends of the rails have a completely identical configuration reversed by 180 °, so that the rails do not have to be turned over during installation, regardless of how they were transported. This is particularly so
• each individual rail can be laterally removed and replaced from the tensioned rail track.
• the hanging bolt is conveniently carried by a shackle that encompasses the two hanging plates.
• the two suspension plates are guided in a particularly simple manner against lateral transverse forces.
• other suitable guide means can also be provided against such horizontal transverse forces.
• suspension bolt In order to keep the specific surface pressure between the suspension bolt and the perforations of the elongated holes as low as possible, provision is further made for the suspension bolt to be flattened on its upward-facing side, the flattening being adapted to the curve radius of the perforation of the elongated holes.
• the suspension forces are distributed over a relatively large area, so that deformations on the surface of the bolt and / or on the perforations of the elongated holes are not to be feared, even with large loads.

• the rails are I-beams, the web of which is arranged vertically, so that the upward-facing surfaces of the lower flanges form the running surfaces 3 for the vehicle wheels of the monorail overhead conveyor.
• the butt joint consists of a joint arranged in the area of the lower flanges, which is designated in its entirety with reference number 4, and the connecting means arranged in the area of the upper flanges, which are referred to in their entirety with reference number 5.
• the joint in the area of the lower flanges has two fastening blocks 6, which are welded under the lower flanges of the rail sections 1 and 2, respectively.
