Abstract

The equipment consists of several sets of hydraulic power cylinders (8) with counter plates (9), guide tubes (10) and extension rods (11). The sets of hydraulic power cylinders are applicable on suitable places of the crusher walls. In these places suitable design provisions are made on the walls to fix the particular power cylinder to the outside of the wall. By applying hydraulic pressure it is possible to push out from its place the fixing wedge (6) as well as the jawplates (4, 5). When jawplates (4, 5) are removed, also side plate (7) can be removed in a similar manner by applying the power cylinder through the side wall of the crusher.

Description

Ausbauvorrichtung für verschlissene Brechplatten Removal device for worn crushing plates

in Backenbrechern Die Erfindung betrifft eine Vorrichtung zum Ausbau von verschlissenen Brechplatten in Backenbrechern mit festen oder/und beweglichen Brechwänden. in jaw crushers The invention relates to a device for dismantling of worn crushing plates in jaw crushers with fixed and / or movable ones Crushing walls.

In Backenbrechern werden die festen oder/und beweglichen Brechwände mit Brechplatten aus hochfestem und verschleißfestem Material, meistens Manganhartstah), versehen. Die Befestigung dieser Brechplatten erfolgt auf den beweglichen Brechwänden meist durch Befestigungskeile, die durch Halteschrauben gegen die Brechwände gezogen werden, dagegen auf den festen Brechwänden durch die Seitenkeile, die gleichzeitig als Schleißbleche für die Seitenwände dienen. Es ist dabei Sorge zu tragen, daß die Brechplatten bzw. ihre Versteifungsrippen satt auf den Brechwänden aufliegen, damit Verbiegungen der Brechplatten durch den Brechdruck mit Sicherheit vermieden werden.The fixed and / or movable crushing walls are used in jaw crushers with crushing plates made of high-strength and wear-resistant material, mostly manganese hard steel), Mistake. These crushing plates are attached to the movable crushing walls mostly by fastening wedges, which are pulled against the crushing walls by retaining screws be, however, on the solid crushing walls by the side wedges, which at the same time serve as wear plates for the side walls. Care must be taken that the crushing plates or their stiffening ribs lie snugly on the crushing walls, so that bending of the crushing plates due to the crushing pressure is definitely avoided will.

Durch die erheblichen Brechdrücke, die beim Brechvorgang auftreten, arbeitet sich im Laufe der Zeit eine Brechplatte in ihre Brechwand mehr oder weniger stark ein.Due to the considerable crushing pressures that occur during the crushing process, In the course of time, a crushing plate works its way more or less into its crushing wall strong one.

Außerdem wird durch die Brechdrücke die Brechplatte gequetscht und infolgedessen weicht das Material in Längsrichtung der Brechplatte aus. Die Brechplatte wird sozusagen ausgewalzt bzw.In addition, the crushing plate is squeezed and crushed by the crushing pressures As a result, the material gives way in the longitudinal direction of the crushing plate. The crushing plate is, so to speak, rolled out or

ausgelängt. Dadurch verspannt sich die Brechplatte zwischen ihren Halterungen.elongated. As a result, the crushing plate is braced between their Brackets.

Es bereitet infolgedessen große Schwierigkeiten und erfordert einen erheblichen Zeitaufwand, die Brechplatten mit ihren Verkeilungen auszubauen, wenn sie aus Verschleißgründen ausgewechselt werden müssen. Meistens müssen die Befestigungskeile und die Brechplatten durch Brennen stückweise entfernt werden.As a result, it causes great difficulty and requires one considerable expenditure of time, the crushing plates with their wedges to expand if they have to be replaced due to wear and tear. Most of the time they have to Fixing wedges and the breaker plates are removed piece by piece by burning.

Es ist Aufgabe der Erfindung, eine Lösung dafür zu finden, daß der Ausbau der Brechplatten in kürzerer Zeit und ohne Brennarbeiten und für das Bedienungspersonal einfacher und arbeitsentlastend erfolgen kann.It is the object of the invention to find a solution that the Removal of the crushing plates in less time and without burning work and for the operating personnel can be done more easily and relieves the workload.

Dies wird erfindungsgemäß dadurch erreicht, daß an den Außenflächen der Brechwände Halterungen für ein oder mehrere versetzbare hydraulische Kraftgeräte mit Druckstempel, die durch Bohrungen in den Brecherwänden auf die auszubauende Brechplatte und ihre Verkeilung wirken können, angebracht sind und daß das/die versetzbaren Kraftgeräte jeweils mittels ihrer Druckstempel zunächst die Verkeilungen nach Ausbau ihrer Halteschrauben herausdrücken und anschließend die Brechplatte von ihrer Auflagefläche lösen bzw. abheben.This is achieved according to the invention in that on the outer surfaces of the crushing walls, brackets for one or more relocatable hydraulic power devices with plunger that is to be removed through holes in the crusher walls Breaking plate and its wedging can act, are attached and that the / the displaceable Power devices each by means of their pressure stamp initially the wedges after removal Push out its retaining screws and then remove the breaker plate from its support surface loosen or take off.

Da die hydraulischen Kraftgeräte entsprechend stark ausgelegt werden können, wird die Ausbauarbeit erheblich vereinfacht und erleichtert. Das hydraulische Kraftgerät wird so stark ausgelegt, daß es zunächst die Verkeilungen nach Ausbau der Verschraubung herausdrücken und anschließend die Brechplatte abschnittsweise von ihrer Auflagefläche auf der Brechwand lösen kann.Because the hydraulic power devices are designed to be correspondingly strong can, the expansion work is considerably simplified and facilitated. The hydraulic The strength machine is designed to be so strong that it initially wedges after removal the screw connection and then the breaker plate in sections can detach from their contact surface on the crushing wall.

Der Erfindungsgedanke ist in der beigefügten Darstellung eines Ausführungsbeispieles kurz erläutert.The idea of the invention is shown in the attached illustration of an exemplary embodiment briefly explained.

Es bedeuten 1 = Feststehende Brechwand (Kopfwand) 2 = Bewegliche Brechwand (Brechschwinge) 3 = Seitenwand 4 = Feststehende Brechbacke 5 = Bewegliche Brechbacke 6 = Befestigungskeil für die bewegliche Brechwand 7 = Seitenkeil (Seitenschleißbleche) 8 = Hydraulisches Kraftgerät 9 = Gegenhalter (Traverse) 10 = Führungsrohr 11 = Verlängerung für Kolbenstange = Druckstempel Die Ausbauvorrichtung, bestehend aus dem hydraulischen Kraftgerät 8, Gegenhalter 9, Führungsrohr 10 und Verlängerung 11, ist so konstruiert, daß sie an verschiedenen Stellen der Kopfwand 1 und der Brechschwinge 2 und erforderlichenfalls an den Seitenwänden zum Herausdrücken der Seitenkeile angesetzt werden kann. Es ist somit möglich, den Befestigungskeil 6 sowie die Brechbacken 4 und 5 herauszudrücken. Bei starker Verspannung war bisher nur durch langwieriges Freibrennen dieser Teile eine Demontage moglich. Die feste Brechwand 4 wird vom Seltenkeil 7 auf der Kopfwand 1 geholten. Ohne Ausbauvorrichtung ist auch diese Brechwand bei starker Verspannung nur durch Frei brennen zu demontieren.It means 1 = fixed crushing wall (top wall) 2 = movable crushing wall (Crusher rocker) 3 = side wall 4 = fixed crusher jaw 5 = movable crusher jaw 6 = fastening wedge for the movable crushing wall 7 = side wedge (side wear plates) 8 = hydraulic power device 9 = counter holder (cross member) 10 = guide tube 11 = extension for piston rod = plunger The removal device, consisting of the hydraulic Strength device 8, counter holder 9, guide tube 10 and extension 11 are designed in such a way that that they are at different points of the head wall 1 and the crushing rocker 2 and if necessary can be attached to the side walls to push out the side wedges. It it is thus possible to push out the fastening wedge 6 and the breaking jaws 4 and 5. In the case of strong tension, this was previously only possible through lengthy burning of these parts dismantling possible. The solid crushing wall 4 is from the rare wedge 7 on the head wall 1 fetched. Without a dismantling device, this crushing wall is also under strong tension can only be dismantled by burning free.
