Definitions

the subject invention relates to a device for application a spring tension on one with a rigid jaw and with a movable jaw designed clamping body for coupling of a hanger on a traction or conveyor rope, consisting of a pot-like housing in which spring elements, in particular disc springs, are arranged and with a protruding from this housing Pipe socket, which with a first external thread in a with a Internal thread trained bore of the sprag is screwed and which between the housing and the first external thread a second external thread is formed, on which a lock nut is screwable.
the clamping bodies of known rope clips are with a longitudinal bore formed in which the actuating plunger for the movable Jaw is guided. This hole is provided with an internal thread, into which the actuator is screwed.
Acquaintances with Actuators designed actuators consist of a pot-like Housing in which a set of disc springs is arranged. Of this housing protrudes with a pipe socket formed with an external thread which is screwed into the clamping body. From the disc springs another plunger goes off, which passes through the pipe socket and which interacts with the plunger located in the clamping body. Furthermore, the pipe socket is also outside of the sprag an external thread on which there is a lock nut, which can be screwed to the clamping body.
this known actuating device therefore does not correspond to technical requirements, since the pipe socket protrudes from the housing in the area which is outside the clamping body and located outside the locknut, high changing bending loads exposed, making it very fragile in this area.
the object of the invention is therefore based on the task to improve such device so that this the known State of the art disadvantage is avoided.
this will achieved according to the invention in that the wall thickness of the second Screw-threaded section of the pipe socket at least 1.2 times the amount of the wall thickness of the screwed into the clamping body Has section of the pipe socket.
the wall thickness preferably has that with the second external thread Provided section of the pipe socket about twice the amount Wall thickness of the section provided with the first external thread of the pipe socket. Furthermore, the length of the section is preferred with the second external thread about 0.5 times to 0.8 times the length of the section with the first external thread.
FIG. 1 shows a rope clamp with a tensioning device according to the invention.
the cable clamp 1 shown in Fig. 1 consists of a clamping body 11, which with a rigid jaw 12 and one opposite Clamping body 11 displaceable jaw 13 is formed. Means this jaws 12 and 13 is the cable clamp 1 to a train or Conveyor rope 10 of a drag lift system can be clamped.
the clamp body 11 is formed with a longitudinal bore 14 in which a plunger 15 is guided is, the right end cooperates with the movable jaw 13. At its end facing away from the jaws 12 and 13 is the bore 14 of the clamping body 11 with an internal thread 16 educated.
a hanger 20 is attached to the clamping body 1.
the clamping body 1 is assigned an actuating device 2, which a Has pot-shaped housing 21, in which there are disc springs 22. From the housing 21 protrudes a raw connector 23, which on its Housing 21 remote end formed with an external thread 26 is, whereby the adjusting device 2 in the internal thread 16 of the clamping body 11 can be screwed in. Inside the pipe section 23 is another Tappet 25 is provided, which is located in its housing 21 End is formed with a disc 24 to which the set of disc springs 22 comes to rest and its other end face on the plunger 15 is present. By the plate springs 22 is on the plunger 25 and Ram 15 on the movable jaw 13 the required force applied to attach the cable clamp 1 to the cable 10.
the pipe socket 23 projecting from the housing 21 is divided into two areas, which with the external thread 26 and with a further external thread 27 are formed.
the section at the free end with the first external thread 26 has an external diameter, which corresponds to the inner diameter of the bore 14.
the section located outside the clamping body 11 with the external thread 27 formed with a much larger diameter, wherein the wall thickness of this second section of the pipe socket 23 approximately is twice the wall thickness of the first section.
a lock nut 28 is screwed on. By the lock nut 28 are on the pipe socket 23 in the area of the lock nut 28 so high tensile forces exerted that the acting on them changing bending forces can not cause breaks of the same.
the pipe socket 23 is therefore not at risk of breakage, because he has a wall thickness approximately twice that of the one Section which is screwed into the clamping body 11.
the housing 21 is also formed with a hexagon 29 through which it is rotatable relative to the clamping body 11. Through the Rotational position of the housing 21 relative to the clamping body 11 is the Tension of the plate springs 22 or thereby the clamping force of the cable clamp 1 set.
a tension bolt 29 is firmly connected to the plunger 25, which penetrates the plate springs 22, which lie on the pipe socket 23 Side protrudes from the housing 21 and at its free end a pull plate 30 is arranged. If the cable clamp 1 is loosened is the tension bolt 29 by means of a hydraulic press tool adjusted against the action of the plate springs 22, which on the movable jaw 13 clamping force is lifted. This can the cable clamp 1 can be adjusted along the traction cable 10 without this complex assembly work is required.
