Definitions
- the invention relates to a receiving and weighing device on the support frame of a transport device for ladles, with a horizontal one each on the supporting frame Axis pivoted levers with inclined Supports and guide surfaces for the Pan support elements.
- a Holding device with weighing elements on the support frame a transport device for ladles, regarding design, manufacture and maintenance is very expensive. Because the weighing elements in this Execution should not be exposed to horizontal loads are allowed, the weighing elements are replaced by a variety of horizontal supports intercepted by special Medium, for example threaded pieces with a fine thread and lock nuts are adjusted so that they as free of play as possible, but also not tense. So that these agents wear out as little as possible they are made of high quality materials and carefully protected against pollution.
- AT-36 73 30 is a weighing device for metallurgical vessels, especially in a continuous caster known with a load suspension device equipped like the pan support arm of a rotating tower with at least two on the load suspension device each around a horizontal axis pivoted levers on which the metallurgical vessel is supported.
- a pressure measuring device between the Load suspension device and the the metallurgical Vessel-carrying levers arranged, being on outside end of each one-armed lever at its A combined load bearing surface is provided on the top is.
- the pressure measuring device is in the vertical direction of force flow arranged and opposite the load suspension device supported vertically.
- Each lever is a single pressure measuring device assigned in the vertical central plane of the lever.
- the lever itself is trough-shaped in cross section designed, the middle trough part of the lever the spherical load bearing surface carries and the higher set lateral ends of the lever at one Load cell are supported.
- DE 35 35 935 is a holding device for Pouring ladles known in which the support frame for rough guidance of the pan support elements arranged laterally Horns with sloping guide surfaces.
- pan support elements are guided through Lateral embellishments reached on the ends a recording bar below the aforementioned Guide surfaces are arranged.
- This support bar is based on the weighing elements from.
- the weighing elements (load cells) are on as fixed bearings on one side and as a floating bearing on the other Side mounted on the support frame.
- a disadvantage of the designs according to both of the aforementioned Property rights is that while putting on strong horizontal and vertical impacts on the pan the levers pivotably mounted on the support frame or on the mounting beams and the lower side Centerings and thus transferred to the weighing elements that are a multiple of the nominal load can.
- the object of the invention is a To create cradle that has the disadvantages of Avoid prior art and a bumpless Put on the ladle support elements of the ladle the support of the weighing device allows.
- the inclination of the surfaces forming the centering is flatter than that of the lower side surfaces of the support elements the ladle and the lower width of the support trough is wider than the maximum possible width of the lower contact surface of the support elements of the ladle.
- the support elements of the ladle in the Support trough not be pinched laterally and the vertical central axis of the ladle or its supporting elements can do little of the vertical central axis the support trough.
- the two levers are with bearings in pedestals stored, which are part of the support frame. Camps can be used as plain bearings or rolling bearings, e.g. B. roles or Needle roller bearings, run so that you Return moment, which is the weighing accuracy could influence, is negligible.
- the bearing centers and the lower edge of the support trough lie on the same horizontal axis, so that horizontal force components that may occur have no influence on the weighing result.
- the two levers are supported in the loaded condition with their support feet on the Contact surfaces of the weighing beam, which in turn turns into known way on the weighing elements or load cells supports.
- Load cells and weighing beams also form the weighing device here for the ladle.
- the arrangement of the weighing beam on the weighing elements or load cells is appropriate, but not essential necessary.
- the levers can also directly on the Place weighing elements or load cells.
- the levers are unloaded by springs superscript.
- the centering is slightly flatter than the side surface of the support elements of the ladle.
- the support trough is slightly wider at the top than that Bottom edge of the support elements of the ladle.
- Both levers are based on the bearings and the return springs on the other hand on damping cylinders from operated with a hydraulic fluid will. When a compressive force acts on the Damping cylinder flows through the hydraulic fluid one or more channels with nozzles or orifices are equipped, from the lower to the upper chamber of the damping cylinder.
- the levers are therefore delayed and slow, i.e. not abruptly on the contact surfaces of the Weighing beam off. Without this damping, short-term Load peaks occur on the weighing elements that be several times the weight of the ladle can. Weighing elements that are dimensioned for necessarily have lower accuracy than those whose maximum load is only slightly higher than the nominal resilience.
- the levers As soon as the lever settles on the weighing beam have and are no longer pushed together can, i.e. no more hydraulic fluid the nozzles or orifices are flowing, the levers also practice no longer exert pressure and thus influence not even the weighing result.
- the force of between the support frame and levers arranged return springs should be in the raised Condition of the lever to be little larger than the force with which is the dead weight of the levers and the frictional torque of the Bearing is lifted in the pedestals.
- the Spring force in the lowered state and the weight of the Weighing device and the empty pan is at Tare the weighing device into account so that only the weight of the ladle or that of the liquid Steel is determined in the ladle.
- the return springs can be inside the Damping cylinders are placed where they are best are protected or outside the cylinder.
- the bearing blocks are parts of the weighing beam.
- the levers sit up in the unloaded state Support frames that are part of the support frame. Impact forces when the pan is placed against the Centering surfaces act largely on the Trestles directed onto the support frame. The pan is resting after touchdown only on the Weighing device.
- Fig. 1 shows the recording device according to the invention with levers (1) raised in the unloaded state.
- the hinged levers (1) are in pedestals (2) attached to the support arm (15).
- the levers (1) rest on the bearing (3) Return springs (6) and on damping cylinders (4) and point to the one opposite the bearing (3) Side an inclined centering surface (14) and one Support foot (1a) on the support surface (12) of the weighing beam (11) of the weighing device (16) with the Load cells (17) in the loaded state.
- the two bearings (3) are in a common one horizontal axis (9).
- the receiving device can, for example, in one Ladle turret of a continuous caster, in one Ladle transport trolley u. a. where the liquid metal is weighed during the casting.
- the inclination of the centering surfaces (14) is somewhat flatter as the lower side (7) of the pan support elements (19) and the width of the support trough (10) by the Support feet (1a) the lever (1) is formed is something wider than the bearing surfaces (7, 7a) Pan support elements (19).
- the levers (1) are therefore delayed and slow, d. H. not suddenly, on the bearing surfaces (12) of the Weighing beam (11).
- Fig. 3 shows an embodiment where the bearing blocks (2) for the levers (1) are part of the weighing beam (11) and where the lever (1) in the unloaded state (dashed version) on the trestles (20) deposit that are part of the support frame (15).
- the levers (1) are superscripted in the unloaded state, that the overall focus of the lever (1) each is outside its camp, i.e. each on the Center axis (8) facing away from the bearing (3).
- the support feet (1a) lie in the lowered state the bearing surface (12) of the weighing beam (11) on and are directly in the middle above the weighing elements or Load cells (17) arranged.
- Fig. 4 shows a plan view of the on the support frame (15) a turret of a continuous caster arranged receiving and weighing device, in which the Bearing blocks (2) for the lever (1) part of the weighing beam (11) are.
- the pan (18) is supported by the pan support elements (19) on both sides of the support frame (15).
