Definitions
- the invention relates to a method for mounting a crushing cone on the cone carrier of a cone crusher, wherein the crushing cone is braced against the conical seat of the cone carrier with the aid of a hydraulic tensioning device by means of a screwed nut on the cone carrier.
- the invention also relates to the corresponding method for dismantling the crushing cone.
- the invention relates to a cone crusher with a cone carrier and on the conical seat of the cone carrier can be placed crushing cone, wherein the crushing cone can be clamped by means of a screwed onto a cone carrier pin of the cone carrier clamping nut against the cone carrier.
- the tip of the cone carrier runs out of the cylindrical cone carrier pin, which is provided with an external thread.
- the thread is used to screw on a clamping nut, which rests with its lower end face on the upper edge of the crushing cone or on the clamping cone acting on the clamping ring. If the clamping nut is tightened, it presses the crushing cone at least in the lower area against the conical seat of the cone carrier, so that the surfaces "wedged" via a lever path and the crushing cone is thus frictionally held on the cone carrier requires the use of heavy tools, such as a striking wrench and / or a heavy hammer, which is not only associated with the risk of accidents, but may result in damage to machine parts if handled improperly.
- the object of the present invention is now to propose an alternative method for assembling and disassembling a crushing cone on the cone carrier of a cone crusher with the aid of hydraulic forces, which is practicable, which can be implemented inexpensively with simple technical means, and with comfortable handling a high tension created between the crushing cone and the conical seat. It is also an object to provide a simple and inexpensive to implement system that ensures a comfortable and safe assembly and disassembly of the crushing cone and ensures the reliable operation of a cone crusher with high performance.
- the essential aspect of the invention is to equip the cone crusher so that for the purpose of assembly and disassembly of the crushing cone, a hydraulic tensioning device can be mounted with simple means on the cone carrier, with the assembly and disassembly in view of the strong Bracing between crushing cone and cone carrier is supported.
- this hydraulic tensioning device is removed before commissioning the cone crusher with a few simple steps.
- the main advantage of the procedure according to the invention is that the hydraulic tensioning device is not exposed to the destructive forces which prevail during operation of the cone crusher and therefore functions reliably.
- Another significant advantage is that commercially available clamping devices can be used in particular in the form of hydraulic nuts. For the use of commercial hydraulic nuts only a few changes to the cone carrier are required.
- the use of the clamping devices according to the invention in the form of hydraulic nuts and corresponding clamping plates makes it possible to convert existing cone crushers in a simple manner for their use of such a hydraulic tensioning device.
- both the hydraulic pressure device and the clamping nut at any time for any repairs accessible.
- the screwed nut is first manually or by means of a clamping ring manually or with ease of use Subsequently, the hydraulic tensioning device is detachably mounted on the cone carrier and actuated With the extension of the hydraulically driven piston, the crushing cone is pressed directly or by means of the clamping ring against the conical seat of the cone carrier while the tensioning device acts on the crushing cone in such a manner, the applied, but now relieved, tensioning nut can be retightened by the path of the tensioning, finally the tensioning device is relaxed and removed from the cone carrier.
- hydraulic nut is used as a clamping device.
- Such hydraulic nuts are used for the assembly and disassembly of rolling bearings.
- the hydraulic nut is screwed by screwing the clamping nut coaxially to this on a located at the top of the cone carrier cone carrier pin.
- the cone carrier journal surrounds a first external thread for screwing on the clamping nut and a second external thread lying behind it in relation to the crushing cone for screwing on the hydraulic nut.
- the diameter of the second external thread is smaller than the diameter of the first external thread and smaller than the internal thread of the clamping nut, so that the clamping nut can be easily guided over the second external thread.
- a clamping plate which acts on the extending annular piston of the hydraulic nut and which is provided as a force and individually adapted to the structural geometry of the cone crusher component. It is advantageous to equip the clamping plate for effective loading by the annular piston with a flat ceiling flange on which the annular piston can create. With regard to a simple structure, it is also advantageous if the ceiling flange to a Clamping nut overlapping pressure ring connects, which acts directly or by means of the clamping ring on the crushing cone. In order to operate the clamping ring surrounded by the pressure ring breakthroughs are provided in the periphery of the pressure ring through which rotary lever can be inserted into corresponding receptacles in the clamping nut.
- the invention can also be used to disassemble the means of the clamping nut screwed on the cone carrier and clamped against the conical seat of the cone carrier crushing cone.
- the crushing cone is first pressed onto the conical seat by means of a hydraulic tensioning device mounted on the cone carrier.
- the clamping nut is then released so far that the later relaxing crushing cone can expand without again bump against the clamping nut.
- the clamping device and with it the crushing cone can be relaxed and disassembled.
- the nut is completely unscrewed and lifted the crushing cone.
- Figure 2 shows the cone carrier pin with mounted hydraulic pressing device
- Figure 3 is a hydraulic nut.
- FIG. 1 shows first a section through the head of the cone crusher according to the invention.
- the crusher abandoned the crusher crushed between the fixed crushing ring 1 of the upper housing part 2 and the seated on a conical seat 13.2 at the foot of the trunnion 4 crushing cone 3.
- the cone carrier 4 is driven over the Exzenterbuchse 5 offset in a tumbling motion, whereby the crushing gap 6 between crushing ring 1 and crushing cone 3 changes continuously circulating.
- the crushed material is crushed by squeezing and impact effect until it can leave the cone crusher through the crushing gap 6.
- the driven eccentric bush 5 rotates in a radial guide about an axis 7, which is firmly clamped in the lower housing part 8.
- the cylinder piston 9 is integrated into the axis 7 and allows the axial displacement of the cone support 4 and thus of the crushing cone.
- the crushing cone 3 is mounted in the above-mentioned procedure on the cone carrier 4 or disassembled from the cone carrier 4, while a hydraulic tensioning device 14 presses the crushing cone 3 with high clamping force into the conical seat 13.2 of the cone carrier 4.
- the support according to the invention is that the crushing cone 3 on the clamping ring 1 1 with the Clamping device 14 is biased before the clamping nut 16 is screwed tight.
- the hydraulic tensioning device 14 has a hydraulic nut 15 and a clamping plate 17 (FIG. 3), wherein the hydraulic nut 15 acts on the cone carrier 4 via the tensioning plate 17.
- the clamping plate 17 is detachably mounted on the cone carrier pin 12 and engages in the plugged state, the clamping nut 16.
- the clamping nut 16 also acts on the clamping plate 17, the crushing cone 3 by means of the clamping ring 1 first
- the clamping plate 17 has an acted upon by the hydraulic nut 15 ceiling flange 23 and the crushing cone 3 by means of the clamping ring 1 1 acted upon pressure ring 24 which includes the clamping nut 16.
- the clamping ring 1 1 thus also provides the pressure ring 24 a plant.
- openings are provided, through which the clamping nut 16 is accessible for plug-in rotary lever 18.
- the rotary lever 18 are temporarily inserted for rotation of the clamping nut 16 in corresponding holes which are arranged in the circumference of the clamping nut 16.
- the cone carrier pin 12 has for screwing the clamping nut 16, a first external thread 25 and a respect to the crushing cone 3 behind, respectively over lying second external thread 26 for screwing the hydraulic nut 15.
- the diameter of the second external thread 26 is smaller than that of the first external thread 25 and smaller than the internal thread of the clamping nut 16.
- FIG. 3 shows a hydraulic nut 15 having an annular body 27 with internal thread and an annular groove in the side surface. In the annular groove an annular piston 28 is inserted. Two sealing rings 29 seal the annular piston 28 in the annular groove. The annular piston 28 is actuated by hydraulic oil, which is pumped into the pressure chamber 30. For the connection of oil lines threaded holes 31 are provided with screwed adapter pieces 32. In a threaded hole, a pressure gauge 33 can be screwed.
- the clamping ring 1 1 is placed centrally over the cone carrier pin 12 on the crushing cone 3.
- the clamping nut 16 is "hand-tight" screwed onto the cone carrier 4, so that the clamping ring 1 1 and the crushing cone 3 rest on the cone carrier 4.
- the hydraulic nut 15 is screwed and operated, so that the crushing cone 3 is clamped hydraulically on the conical seat 13.2 of the cone carrier 4.
- the clamping nut 16 is screwed by means of the inserted rotary lever 18.
- the disassembly of the crushing cone takes place according to the following steps: The impact helmet 22 is removed.
- the thread protector 19 is unscrewed.
- the clamping plate 17 is placed and the hydraulic nut 15 is mounted.
- the clamping nut 16 is unscrewed and the clamping ring 1 1 lifted.
