Definitions
- the invention relates to a quick-change device for earthmoving vehicles for replacing work tools, which are releasably connected to the boom of the earthmoving machine about a horizontal axis with this adapter, which is designed as fixed claws and is mounted as a displaceable locking bolt, with coupling elements that correspond to them on Appliances are assigned, of which the one coupling member has an opening for the entry of the sliding coupling members locking plate and the other coupling member forms a coupling axis at least partially encompassed by the claws, the bracing between the adapter and the implement taking place via the abutment surfaces of the coupling members.
- EP-A 0 273 828 shows such a fixed and displaceable coupling member quick change device. Since space is required for pivoting and pivoting the adapter into the implement relative to the locking plate, this is correspondingly far away from the coupling axis to be gripped by the claws, so that when coupling only the claws with the coupling axis and the bolts with the openings in the locking plate are clamped. Due to this design of the coupling members, only a uniaxial bracing between the implement and the adapter on the boom takes place via the abutment surfaces of the coupling members. However, such a connection is not sufficiently rigid for heavy earthmoving operations.
- the coupling members fixed to the housing have a coupling axis on the implement and these partially comprehensive receiving claws on the boom
- the displaceably mounted coupling element being a spring-loaded wedge which interacts with the fixed coupling element arranged on the implement in the form of a hook
- the wedge can be locked outside the active position by a locking device which is triggered during the coupling process between the boom and the implement, so that for the purpose of locking the wedge slides under the hook under the action of the spring; see AT-B 389 906.
- displaceable coupling members as locking bolts which can be inserted into associated bores in a support plate of the implement via a lever mechanism; see DE-B 1 784 323.
- these quick-change devices also have in common the complex training and the susceptibility to faults, taking into account the rough use in earthmoving work. Also, with these quick-change devices, the goal of carrying out a change of work equipment by the driver of the earth-moving machine without additional help personnel alone cannot be achieved.
- the object of the invention is to further develop it in such a way that using fewer and also taking into account the unavoidable wear over long operating times, reliable components reliably lock the implement and boom of an earth moving machine alone from the driver.
- the one abutment surface of the coupling members of the adapter is designed as a cylindrical jacket-shaped abutment surface delimited on both sides by the claws for the purpose of support on the lateral surface of the coupling axis of the implement, while the other abutment surface is flat and forms an imaginary plane connecting the two abutment surfaces is arranged at an incline that the locking plate has an abutment surface facing the adapter and corresponds to the abutment surface and corresponds to the full surface in the locked state, and that the abutment surfaces with the surfaces of the displaceable coupling elements and the openings in the locking plate corresponding to them slide and tighten form mutually facing abutment surfaces of the adapter and the implement force wedge gear.
- the coupling surfaces of the displaceably mounted coupling members of the adapter and the coupling members of the implement are designed and assigned to one another in such a way that they form a wedge gear that clamps the adapter housing and the adapter plate together.
- the coupling surfaces of the displaceable coupling members and the coupling surfaces of the associated coupling members of the locking plate are designed as conical lateral surfaces which correspond to one another over a circumferential angle of approximately 180 °, the circumferential partial surfaces of the coupling elements assigned to the locking plate being complementary to 360 ° and having the associated Include a predetermined bearing clearance circumferential surface areas of the sliding coupling members.
- the inventive design of the locking components of the quick-change device has the advantage that during the locking process, the locking bolts essentially have a supporting function in the upper lateral surface half of the truncated cone-shaped area and the oblique clamping surface of the adapter housing slides over the entire surface onto the oblique clamping surface of the locking plate, so that with a multiaxial bracing of adapter and implement takes place simultaneously with the initiation of the control process.
- the adapter housing is pressed forward against the coupling axis, and the preferably elliptical space between the locking bolts and openings in the locking plate ensures that the locking bolts continuously adjust, that is to say can move into the locking position.
- the locking bolts which are under spring tension, thus assume a low-tension function, whereby the contact claws on the coupling axis create a surface pressure between the above-mentioned inclined surfaces.
- centering elements By means of the centering elements, a pre-centering is achieved when lowering the adapter housing onto the adapter plate assigned to the implement, which not only facilitates the locking process and significantly reduces wear due to canting between the adapter housing and implement, but also makes it possible to change implements without instructions.
- the switching shaft of the locking device can be driven both mechanically and hydraulically, in the mechanical embodiment, an articulated lever mechanism with locking via dead center, and in the hydraulic embodiment, the locking bolts are articulated via an oscillating pressure compensation bridge and a hydraulic cylinder.
- a quick-change device designated as a whole in FIG. 1 with the reference number 10 comprises an adapter, consisting of adapter housing 30 and adapter plate 12, of which the housing 30 is associated with an extension arm, not shown here, of an earthmoving machine, also not shown, and the adapter plate 12 is associated with the implement, also not shown so they are firmly connected.
- the adapter plate 12 comprises a base plate 14 on which a locking plate 16 is welded at one end and a coupling axis 19 is welded at the opposite end by means of fastening tabs 17.
- the locking plate 16 has on the side facing the coupling axis a clamping surface 20 which is inclined to the vertical surface 20 'by 3 ° to 35 °, preferably by 5 ° to 15 °.
- the locking plate 16 is furthermore, as can be seen in particular from FIG. 3, provided with two openings 21 and 22 which are arranged at a distance a from one another and have a conical cross section.
- the cone angle of the openings delimited by conical surface areas is dimensioned accordingly and is 5 ° to 15 ° in the exemplary embodiment shown.
- the approximately cuboidal adapter housing 30 has a receiving claw 31 on its side faces, which in the retracted state - see FIG. 2 - encompass the coupling axis 19.
- the end face of the housing 30 located between the receiving claws 31 merges into an abutment surface 32 in the form of a cylindrical jacket, which — as also shown in FIG. 2 — is supported on the cylindrical jacket surface of the coupling axis 19 in the retracted state.
- the opposite end face 34 is inclined by 3 ° to 35 °, preferably by 5 ° to 15 °, with respect to the vertical - corresponding to the clamping surface 20 of the locking plate 16 - and also has two openings 35 through which one in the housing 30 is mounted so as to be longitudinally displaceable Latch bolt 36 can pass through.
- Each locking bolt 36 has a spring 38 which is arranged in a blind bore 37 and which is supported with its free end on a spring plate 39 to which the end face of an angle lever 41 is assigned.
- the angle lever 41 is articulated by means of a connecting bolt 42 on a switching cam 43 which is fixedly connected to a switching shaft 44.
- the facing arm of the angle lever 41 is connected in an articulated manner to the locking bolt 36 by means of a connecting bolt 45 which extends through an elongated hole 46 at the facing end of the locking bolt 36.
- the parts described above form a known toggle lever mechanism, which is driven via the selector shaft 44 and moves beyond the dead center position - imaginary connecting line of the center points of the selector shaft 44 and connecting bolt 45 - when moving from the rest position shown in FIG. 1 into the working position shown in FIG and locked with it. In this way, automatic release of the extended locking bolts 36 from the locking position shown in FIG. 2 is prevented.
- the opposite ends 50 of the locking bolts 36 are frustoconical in shape with a cone angle of 5 ° to 15 ° and correspond to the openings 21, 22 in the locking plate 16, as can also be clearly seen from FIG. 2.
- centering members are provided, of which the centering members assigned to the adapter housing 30 are designed as cylindrical pins 52 (FIG. 1) which lie in the flat end face 34 on both sides of the displaceable locking bolts 36.
- the centering members assigned to the locking plate 16 are inclined surfaces 51 (FIG. 3) lying in the lowering path of the adapter housing 30.
