Definitions

  • the invention relates to an open clamping ring referred to in the preamble of claim 1. Art.
  • clamping rings For the connection of end flanges having pipes or for attaching lids to containers or drums and to determine other round equipment components clamping rings are often used, whereby a variety of Versehraubitch is avoided.
  • Such clamping rings have according to the flanges of the tubes, containers or equipment components different cross-sectional profile shapes and ensure the contraction and sealing of the components together.
  • the open clamping rings are provided with one or more turnbuckles, which connect the free ends of the clamping rings together and pull them together when closing or press apart when opening.
  • a particularly simple lock design consists of a running in the circumferential direction of the clamping ring screw which passes as a flap at right angles bent ends of the clamping ring, and a seated on the screw or on one of the lobes nut.
  • This screw and nut turnbuckle can be operated with a screwdriver or a wrench.
  • Turnbuckle Bolts or rollers are provided which are rotatably mounted in these corresponding retaining lugs provided at the ends of the clamping ring and which are passed through by the tensioning screw. be set.
  • Such screw locks are known from DE 197 28 655 Al.
  • lever locks are provided in particular in frequently operated clamping rings, in which the clamping screw is replaced by a toggle lever or the like lever.
  • the lever since the lever always allows only the same closing path, such a clamping ring is unsuitable when using device components with varying circumference.
  • this To adapt the clamping path, this must be adjustable, for example, with an additional clamping screw.
  • Such a structure is expensive because of the significantly higher production costs.
  • such a cam lock must be secured with additional measures against self-opening.
  • Another disadvantage is that an adjustable cam lock after repeated closing and opening in a time-consuming manner must be readjusted to maintain the correct voltage.
  • the invention is therefore an object of the invention for a particularly suitable for such applications clamping ring - ie a clamping ring of larger diameter with long clamping paths with limited accessibility - to create that can be quickly and safely closed or opened.
  • a double spindle is provided as a clamping screw, the ends of which are provided with opposing threads, ie a right-hand thread and a left-hand thread, which threaded plates and threaded rollers are assigned with corresponding internal threads in the attached to the clamping ring end bearing blocks to a parallel To the clamping ring axis extending axis are pivotally mounted.
  • the threaded ends are each equipped with internal multiple edge, preferably hexagonal edge, in which Allen key or similar tools can be used.
  • the middle part of the double spindle located between the ends is furthermore designed as a multiple edge, preferably a hexagon.
  • the closing or opening speed is doubled.
  • tools namely open-end wrench for the middle part and Allen key for the provided at the ends of the inner multiple edges or open-end wrench for the middle part.
  • the clamping ring can be easily and quickly assemble or disassemble even with limited accessibility.
  • the very stable and largely unbreakable trained screw lock is inexpensive to produce.
  • End position is located, apart. When using electric or pneumatic screwdrivers this can happen very easily.
  • the left-hand thread can hardly be visually distinguished from the right-hand thread, it is proposed according to claim 3 to color the threaded plates or the thread rolls differently. So you can, for example, the left-handed threaded plate or Thread roll in the surface treatment colored, preferably red, mark.
  • a still safe solution is proposed according to claim 4, according to which at least at one end of the double spindle, a stop, preferably a threaded ring, is provided, which is firmly connected to the double spindle, preferably glued.
  • a screw lock designed according to the invention is provided in which threaded rollers are provided instead of the threaded plates.
  • the bearing blocks can be dimensioned such that even in the fully closed state, the circumferentially protruding ringenen- are largely covered.
  • FIG. 4 shows a perspective and partially broken view of a screw lock connected to the clamping ring with the clamping ring open
  • FIG. 8 is a side view of a bearing block according to a second modification
  • FIG. 10 is a perspective view of a bearing block according to a second embodiment of the threaded roller of FIG. 9,
  • FIG. 11 perspective view of a double spindle with trained in the form of a cylinder middle part
  • FIG. 12 perspective view of a half of a clamping ring connected to the screw lock according to a further embodiment. Identical parts are denoted by the same numerals, modified parts by numbers with dash indices.
  • the double spindle 1 which is important for the invention, as shown in FIG. 1, has a right-hand thread 2 on the right-hand side in FIG. 1 and a left-hand thread 3 on the opposite side.
  • the middle part 4 is formed as a solid, short hexagonal profile, which, as indicated by Fig. 5, is easily operable with a wrench 23 formed as a wrench.
  • the threaded sections 2 and 3 of the double spindle 1 are associated threaded plates with matching right-handed or left-handed internal thread.
  • These threaded plates 6 and 10 are equipped on both sides with round cross-section axes of rotation 9, which are closed at the end with cuboid end plates 9a, 9 grooves 8 are formed between the threaded plate 6 and the end plates.
  • the threaded plates 6 and 10 are pivotable about an axis parallel to the clamping ring axis.
  • the threaded portion 10 associated with the threaded portion 3 of the spindle 1, as shown in Figures 4 and 5, is identical, but provided with a left-handed internal thread 11.
  • the bearing block 12 formed from the side walls 15 and connecting them central web 18 has a substantially U-shaped cross-section.
  • the side walls have slot-like design
  • Breakthroughs 16 which are dimensioned such that the rotated by 90 ° threaded plates 6 and 10 can be inserted into this.
  • the areas facing the clamping ring 13, namely the tension sides of the apertures 16 are formed semicircular, so that the axes of rotation 9 of the threaded plates 6 and 10 can create these form-fit and non-positive and rotatable.
  • the side walls 15 are to be dimensioned so that they are not deformed even at the highest possible load by the tensile force of the double spindle 1.
  • the to be connected to the clamping ring 14 center web 18 and the side walls 15 are curved so that they are adapted to the clamping ring outer diameter.
  • Fig. 4 the clamping ring 14 is shown with the inventively designed screw lock in the open state.
  • the two ends 13 of the clamping ring 14 are equipped with bearing blocks 12 according to Figure 3, which are connected to the top of the clamping rings 14 by latching, welding, riveting or the like.
  • the threaded plates 6 and 10 are used in the manner described with reference to FIG. 3, whereupon the ends of the double spindle 1 having right and left-hand threads 2, 3 are screwed into their internal threads 7 and 11 so that only a few Threads in the limited by the side walls 15 interior of the bearing blocks 12 protrude.
  • Ends 13 of the clamping ring 14 are frontally adjacent to each other.
  • the threaded portions 2 and 3 of the double spindle 1 are completely screwed into the threaded plates 6 and 10, however, are still largely protected in the limited by the side walls 15 Interior of the bearing blocks 12.
  • Their protruding ends are marked with the double arrow 24, which simultaneously the maximum Clamping path illustrated. If longer clamping distances are required, longer double spindles 1 should be used accordingly.
  • the operation of the screw lock are simple hand tools, namely alternatively a fork wrench 23, which is to be attached to the formed as a hexagon center part 4, or Allen key 22, which are alternatively used in the hexagonal edge 5 on the right in Fig. 5 and left side of the double spindle 1.
  • the screw lock can be operated even in the most unfavorable mounting situations, namely from three sides.
  • a very fast operation is possible by means of the Allen key 22, which are advantageously clamped in the form of so-called bits in an electric or pneumatic screwdriver.
  • the auf dichote from the front fork wrench 23 may also find particular application when, for example, rusty locks extremely high torques are required.
  • Another advantage of the screw lock according to the invention is that it allows double closing and opening speed because of the provided with right and left-hand thread 2 and 3 double spindle 1. This is especially important for long closing distances, especially when the closing drive is done manually.
  • the screw ends 19 do not protrude as far as in the closed state, as is the case with screw locks with single-spindle screws. In general, the ends 19 are located between the side walls 15 of the bearing blocks 12 protected, which leads to the reduction of the security risk.
  • the threaded rollers 21 also have axes of rotation 9 'at both ends, which are bounded at the end by end plates 9a', so that they form an annular groove 8 '.
  • the most universal screw lock according to the present invention has a double spindle with a center part designed in the manner of a hexagon.
  • FIG. 11 illustrates a double spindle 1 'shown in FIG. 11 which has a cylindrical central part 25.
  • FIG. 12 illustrates a measure for securing the double spindle 1 '. This has at its left end a stop ring 26 which is screwed onto the outermost end and fixedly connected to this, preferably glued. This ring, which rests on the outside of the threaded plate 10 in the end position of the opened screw lock, prevents the double spindle 1 'from being completely unscrewed from the threaded plates and thus the screw lock decoupling into its individual parts.
