Definitions
- the invention relates to a ring lift crane according to the preamble of Claim 1.
- a well-known ring lift crane is in the Mannesmann Demag construction machinery company brochure "Ring lift Granes" CC 2000 RL; CC 4000 RL, edition 11/82.
- This Ring lift crane has a ring that can be erected and a circular lane on, which consists of several interconnectable segments.
- Within the Ringes is an undercarriage and one that is rotatably connected and several winches having superstructure arranged.
- the superstructure is included in both end areas each connected to an adapter, which is arranged on the adapters via Swinging interconnected roller sets on the circular track of the ring support rolling.
- the center of the ring or undercarriage is the center of this the axis of rotation.
- One adapter is for holding a counterweight and one other adapter as a support element for one articulated at the free end of the adapter arrangable boom designed.
- the rotary movement of the ring lift crane is by means of a ring gear arranged on the inside of the ring and therein engaging pinion mounted on rockers.
- To stabilize the Overall construction is the undercarriage with different reinforcement struts Sections of the ring connected.
- This Ring lift crane consists of a stand-up ring that forms a circular track and a construction within the ring with a kingpin and one Platform which is provided with a sleeve for receiving the kingpin.
- the platform is connected to an adapter in each of the two end areas Support roller sets arranged on the adapters by rolling on the ring, whereby the center of the ring forms the axis of rotation for the platform.
- the one-piece ring is secant and within the Stiffened ring struts.
- two parallel struts each have a piston-cylinder unit arranged on their a support leg can be arranged at the free end.
- the caterpillar can be locked with the support element. In this way, the ring lift crane is considered The whole can be moved.
- a disadvantage of the latter construction is that the size of the Ring diameter and thus the maximum load capacity is limited. Besides, is the type of connection of the ring lift crane with the transport unit cumbersome. Furthermore, the undivided ring requires a lot of space when moving the ring lift crane depending on the local conditions at the place of use is not always available.
- a generic ring lift crane is known from US-PS 4,196,816. This consists of a stand-up, a circular lane and several ring having interconnectable segments, within which a Undercarriage is arranged, one rotatably connected and several Superstructure with winches and two at a parallel distance from each other has lying bridge girders, which are in two opposite one another Provide end areas with an adapter and the crossbar with the The uppercarriage can be connected and unlocked.
- the adapters are supported by arranged rollers unrolling on the circular lane of the ring, the The center of the ring or the undercarriage forms the axis of rotation.
- One adapter is to hold a counterweight and the other adapter to hold one articulated boom.
- To generate the rotary movement of the Ringliftkranes is a sprocket arranged, its rotary motion on the two Bridge girder is transmitted.
- the undercarriage is attached with stiffening struts different sections of the ring connected.
- the disadvantage here is that the components of the crane when swiveling and driving are supported on the ring and thus on the undercarriage. Because of too little The drive power of the crawlers must first be for driving and swiveling Counterweight reductions are made. Because the counterweight is not can be moved, further disassemblies are required to balance the crane (e.g. Boom parts) required. So that the crane can swing or drive, it must on Ring are supported and the support plates are either to be removed completely or turn them all up individually.
- the crane e.g. Boom parts
- the object of the invention is to provide a ring lift crane of the generic type, which is space-saving in a simple manner and without counterweight reductions and without Partial disassembly can be pivoted and moved.
- many components can be used as modules for different ring lift classes.
- the bridge girders can be lifted in and in relation to the basic device are non-positively connectable to the cross members, in which Starting position, the positive connection between the bridge girders and the cross members has a predetermined play and several for the rotary movement Identical two axles and wheels attached to them Ring wagons are provided, on the one hand with the bridge girders and on the other hand are positively connectable to the ring or a ring segment. At least an axis of the arranged under the boom or under the counterweight Ring carriage can be driven.
- the previously customary ring gear and the elaborate pinion drive is eliminated.
- each cross girder arranged standing bolt having a stop.
- the stop works together with a bearing block that surrounds the bolt Bridge girder is attached.
- the distance between the top of the cross member and the plate of the bolt on the one hand and the distance between the base plate of the bearing block to stop the bolt on the other hand can by on the top of the Cross-member sliding spacer plates partially or almost completely filled become.
- the spacer plates can be bolted and deblocked using driver pins.
- each bridge support consists of the normal one Road transport suitable sections that can be bolted and deblocked.
- Each bridge girder is preferably on each end face an elbow attached at its free end to the piston-cylinder unit is connectable.
- the ring in a known manner from several interconnectable segments consists of several segments in a space-saving manner before the process of Cranes can be dismantled. Two opposing segments are with the Bridge girders can be locked via the ring trolleys and can be moved along. The tangential extent of these lockable segments corresponds at most the width extension of the counterweight.
- the ring car be supported on two concentric rings leave so that the Hertzian pressure for the in contact with the ring surface stationary wheels remain below the permissible maximum value.
- the Split the total load in half onto two rings.
- Around the ring carriage in the circumferential direction To be able to move the two rings are two opposite each other Carriage connected to each other via a link arm.
- Two on the inside Ring and two carriages arranged on the outer ring form a unit and form the minimum car population.
- Such a unit can be combined with another similar unit can be connected to each other via a bridge element.
- the Linking the car with each other is designed as a plug-in connection.
- the maximum number of ring carriages that can be arranged on a ring is equal to or less than the arc length of the individual ring segment divided by the length of the ring carriage.
- the angular section of the ring segment is preferably 60 degrees.
- the Ring trolleys are constructed identically and are suitable for a ring with a small one Diameter, e.g. B. 21 meters and for a ring with a large diameter, e.g. B. 32 meters. This is realized in such a way that the through the intersecting Center lines of the two axes result in included angles of the mean is between the angle for the smallest and the angle for the largest Ring diameter.
- the resulting impairments in the rolling behavior of the Ring carriages with a ring diameter deviating from the mean value become aware accepted.
- the different rolling path of the on the outer area of the Ring rolling wheel compared to the rolling on the inner area Wheel is balanced by a different diameter. So that Ring wagons, however, continue to lie horizontally, the ring track becomes an exterior and an exterior Inner track divided with an intermediate step, the height of which is half Wheel diameter difference corresponds.
- the positive connection between Ring trolley and ring or ring segment is arranged on the ring trolley Support plates that are provided with a hook roller at the end. These are among the Upper chord of the ring and thus limit lifting of the ring carriage.
- the center of gravity of the ring lift crane is, among other things, essentially determined by the Positioning of the counterweight in relation to the basic device is determined. to A change in this focus is therefore proposed under the platform for the counterweight to arrange counterweight car, whose wheels on the Unroll the top of the bridge girders. In the same sense will continue suggested lying in the area of the counterweight end of the two Bridge girder an extension of the bridge girder projecting beyond the ring to arrange. Both measures have the following advantages: The counterweight can be moved from the position of the normal working position to the counterweight car Towards the center of rotation. This will optimize the focus for moving the ring lift crane on site.
- the Ring lift crane has a modular structure and as many standardized components as possible be used. This starts with the undercarriage and superstructure, the components of a standard crane. This continues through the boom used and the Winches, as well as the crane cab.
- the boom can be used as a single or as so-called double boom can be formed.
- the latter construction has the Advantage that the individual elements of a lower sick class assembled double boom are easier to transport and a can transmit a higher load torque than that from a larger crane class single boom used.
- the multi-section Bridge supports can be used for a single ring as well as for a double ring.
- the Ring wagons are typed and depending on the load to be transferred the number of Ring wagon increased or decreased and linked accordingly. To the To simplify assembly and disassembly, wherever possible, with Plug connections worked so that individual components by means of an auxiliary crane can be raised and inserted.

Description
- Schwenkverriegelung Da das Grundgerät bei den hohen Auflasten nicht mehr auf der Stelle in eine andere Fahrrichtung schwenken kann, wird das vorgeschlagene Verriegelungssystem als Hilfsmittel genutzt. Der Grundkran und der Ring werden mit Hilfe der an den Enden der Brückenträger befestigten Kolben-Zylinder-Einheiten angehoben, wobei zuvor zwischen den Querträgern und den Brückenträgern mittels verschiebbarer Distanzplatten eine kraftschlüssige Verbindung hergestellt worden ist, so daß die Querträger und damit der Oberwagen mit angehoben werden. Dann wird mit Hilfe des Drehwerkes am Oberwagen der Unterwagen zusammen mit dem Ring in die gewünschte Fahrtrichtung geschwenkt.
- Fahrverriegelung Bei dieser Art der Verriegelung werden die Brückenträger und der Ring mittels der vier an den Enden der Brückenträger befestigten Kolben-Zylinder-Einheiten angehoben und nach kraftschlüssiger Verbindung zwischen den nicht angehobenen Querträgern und den Brückenträgern mittels einschiebbarer Distanzplatten kann der Unterwagen geradeaus fahren - und zwar vorwärts als auch rückwärts.
- Arbeitsverriegelung Durch das Verriegelungssystem ist es möglich, den Ring, die Brückenträger und das Grundgerät bei der Kranarbeit als zusätzliches Gegengewicht einzusetzen. Das erspart unter Umständen ca. 10% des Gegengewichtes und den dazugehörigen Transport.
