Definitions

  • the invention relates to a load cross member, which has at least two clamping brackets, preferably arranged in the end regions of the cross member, beneath a central suspension link serving for hanging in a lifting device.
  • two-leg chain slings with clamping brackets for example tensioning clamps or lever clamps
  • clamping brackets for example tensioning clamps or lever clamps
  • the chain slings require a lot of space, so that their use is excluded wherever low construction heights and tight space conditions are available, such as in particular in mine pit extensions.
  • a crossbeam used for this purpose has, in addition to a central suspension link (eyelet), fastening elements arranged at both ends of the crossbeam, i. H. Clamping brackets, which are also designed with eyelets and surround the crossbeam penetrating bearing bolts. With the middle eyelet, the traverse is hooked into the hook of a transport vehicle, for example a trolley, while the outer eyelets are equipped with lever clamps.
  • eyelet central suspension link
  • Clamping brackets which are also designed with eyelets and surround the crossbeam penetrating bearing bolts.
  • the invention has for its object to design a load beam with end-side, self-clamping fasteners so that a compact unit is present, even in confined spaces, in particular can be used in underground construction, and for the safe transport, in particular also for long-distance transports of heavy goods, for example tank conveyor troughs required in mining, the weight of the goods to be transported as well as influences such as braking decelerations with simple mechanical effects
  • this object is achieved by a force transmission and tension element which is exposed to the load-related forces and which couples the clamping brackets to one another and which is preferably designed as a link chain.
  • this allows the lifting force to be divided, and on the other hand, vibrations and / or braking decelerations lead to an effect which directly influences the holding force of the clamping brackets, the contact pressure of the clamps adapts accordingly, namely increases;
  • This effect is mainly due to the fact that the clamp brackets are directly coupled to one another depending on the movement.
  • load-related forces are to be understood here, in particular the forces acting during acceleration and deceleration.
  • the middle suspension link of the load crossmember can be designed as a loose element with a guide for the link chain, the chain looping around the guide like a loop and its two chain strands thus formed being deflected by deflecting pieces into a horizontal plane and the ends of each being connected to a clamping lever of the clamp brackets are attached; the clamping brackets advantageously have a pivotable clamping lever and a counter surface for the lever.
  • the opposing deflection of the chain strands into the horizontal favors the compact design of the load beam, so that despite the common coupling link there is a lower overall height than conventional devices.
  • the distance of the loose, middle suspension link from the crossmember can then be reduced to a minimum if the deflection pieces are arranged one behind the other and are mounted on a common axis.
  • a sufficiently low construction can also be achieved by means of separate, parallel, spaced axes for each deflection piece.
  • the guide of the middle suspension link and the deflection pieces are designed as preferably loosely mounted chain nuts, which bring about a secure chain guide. Due to the loose chain nuts, an automatic length compensation of the chain strands can be achieved, for example with different thicknesses of the transported goods at the clamping points.
  • a rope can also be used as a force transmission link, in which case the chain nuts are advantageously replaced by bolts with spiral grooves as guide and deflection elements (play winch principle).
  • protective housings can also be prevent the chain from jumping out of the deflection pieces, ie the chain nuts, under extreme conditions.
  • the pivotable levers are preferably mounted on transverse bolts between longitudinal walls which are rigidly connected to one another to form a frame, and the counter surfaces for the pivotable levers are formed on the end faces of the frame.
  • the longitudinal walls thus protect the operator and also protect the moving components against external influences.
  • the front side of the frame still - usually referred to as "counter-strikes" - counter surfaces for the pivotable levers, so that the cross-member at the same time as a base frame for the integrated clamping elements, i. H. Clamping brackets.
  • the safety of the operating personnel can be further increased by a housing encapsulating the guiding of the middle receiving link, since the chain run is shielded in this way.
  • pre-tensioned eccentrics acting on the pivotable levers of the clamping brackets can be arranged in the frame of the load crossbar.
  • the eccentrics which are pretensioned to approx. 50 Kp by means of springs, press the clamping brackets firmly onto the goods to be transported, even before the load is lifted, which ensures secure holding from the start. If the goods to be transported are no longer under the influence of the load-related changing forces stands, the eccentrics act on the transported goods until the pretension is released manually.
  • the horizontal conveyance of the goods to be transported in particular also on rising and falling routes, can be supported by strips fastened on the inside opposite one another on the longitudinal walls, each of which has a plurality of recesses spaced apart from one another.
  • the attachment point of the truss frame can then be changed by moving the axis carrying the chain nuts until the transported goods are in balance.
  • the cargo can also be picked up to the side of the attachment point.
  • a load beam with a frame that is adjustable in width for example in the case of two-part longitudinal walls coupled by a plug connection, can be variably adapted to goods of different widths.
  • the load beam 1 consists of two longitudinal walls 2 connected to one another in a rigid frame, of which green which the front longitudinal wall has been omitted for clarity in the drawing.
  • the crossmember 1 has a central, in the operating position shown, that is to say when the load is suspended, a loose suspension link 3 lifted from the longitudinal walls 2 and, as an integrated component, clamping brackets 4 on the end faces.
  • These are each composed of a pivotally mounted clamping lever 6 on a bolt 5 and cooperating counter surfaces 7.
  • the counter surfaces 7 are designed as so-called clamping mushrooms which can be pivoted about an axis; they adapt automatically to different inclinations of the profile of the goods to be transported, and are received by end projections of the interconnected longitudinal walls 2.
  • the clamp brackets 4 hold a tank conveyor trough 8 with sigma-shaped outer walls; Such channels are used in particular in mining to extract and mine coal.
  • the pivotable levers 6 of the clamping brackets 4 and the middle suspension link 3 are coupled to one another by a link chain 9.
  • the chain 9 wraps around a guide 11 encapsulated by a housing 10 and runs from there in two chain strands.
  • Each chain strand is assigned a deflection piece 12, 13, which are arranged coaxially one behind the other and are loosely supported on an axis 14 bridging the distance between the longitudinal walls 2.
  • Both the guide 11 of the master link 3 and the deflection pieces 12, 13 are designed as chain nuts.
  • the chain strands each wrap around the guide 11 and the associated deflection pieces 12, 13 and are fixed with their end links 15 to the pivotable levers 6, so that they are in a horizontal position after the wrapping around the deflection pieces 12, 13 Level.
  • Chain guides 16 arranged below the deflection pieces 12, 13 prevent the chain from unintentionally jumping out of the deflection pieces 12, 13.
  • each pivotable lever 6 is assigned an eccentric 20, for example preloaded by means of a spring 19, as shown for the lever 6 on the left in FIG. 1, with which the lever can be clamped or opened against the transported goods.
  • the eccentric 20 is pivoted when a handle 21 is actuated and the adjustment is transmitted via a linkage 22 to the lever 6; the clamping lever 6 is either fixed or opened against the bias by the spring 19.
  • two leaf springs 23 are arranged which act constantly against the axle with the deflection pieces and which are depressed to move the axle 14 into another recess 18 and moved in a guide into the new position will.
