Definitions
- the present invention relates generally to a crane boom for a mobile crane and in particular to a mobile crane boom with an independent energy supply arranged thereon for generating hydraulic energy, with which various arranged hydraulic consumers can be fed to the mobile crane boom.
- the present invention relates to a crane boom extension with a self-sufficient energy supply and a hydraulic supply to a hydraulic consumer arranged on a mobile crane boom.
- the hydraulic supply of all hydraulic consumers arranged on a mobile crane is usually provided with a single hydraulic pump arranged centrally on the superstructure of the mobile crane, which is driven by a diesel engine also arranged on the superstructure. With the help of this very powerful hydraulic unit consisting of hydraulic pump and diesel engine, all hydraulic consumers arranged on the mobile crane are fed.
- the hydraulic unit which is centrally located on the uppercarriage, primarily supplies the luffing gear, which is also located on the uppercarriage, with hydraulic energy.
- the telescopic sections that can be telescoped into and out of the main boom of the main boom, for example, are mounted in the base box arranged, hydraulically operated telescopic and locking device retracted and extended.
- the locking and telescopic device is connected to the hydraulic unit arranged on the superstructure via hydraulic hoses which are wound up on a hose drum.
- hydraulically luffing main boom extensions are actuated with the hydraulic unit centrally located on the superstructure.
- the luffing cylinder required to rock the main boom extension up and down is supplied with energy centrally by the hydraulic unit arranged on the superstructure via corresponding hydraulic hoses. So that safe management of the
- Hydraulic hoses can be ensured, the hoses are wound on a driven or spring-loaded hose reel, from which they are unwound during the telescopic process.
- a mobile crane boom with an autonomous hydraulic unit arranged thereon for feeding at least one hydraulic consumers arranged on the crane boom are provided with hydraulic energy.
- the hydraulic unit is arranged above the first third of the boom - measured from the articulation of the boom on the superstructure.
- the boom is a telescopic crane boom, the arrangement of the
- a mobile crane boom is provided with a first boom section comprising a main boom and an autonomous hydraulic unit which is suitable for supplying hydraulic energy to at least one hydraulic consumer arranged on the crane boom.
- the hydraulic unit is arranged either on the head of the first boom section or on a second boom section that can be attached to it.
- the hydraulic consumer arranged either on the head of the first boom section or on a second boom section that can be attached to it can be, for example, a first piston-cylinder unit that is suitable, for example, for rocking up and down on the second boom section, which is rocked on the first boom section.
- the invention is therefore based on the idea of not supplying the hydraulic consumers arranged on the mobile crane boom with the aid of a hydraulic unit, for example centrally arranged on the superstructure of the crane, which provides the hydraulic energy to the respective hydraulic consumers via hoses, but rather the supply of the hydraulic consumers Hydraulic consumers with the help of a decentrally arranged
- hydraulic unit which is arranged in the vicinity of the respective hydraulic consumer and in particular in the upper region of the mobile crane boom or in the region of the linkage of a possibly existing second boom section and is thus in the vicinity of the piston-cylinder units to be supplied there.
- the section of the mobile crane boom referred to here as the first boom section can be, for example, a telescopic main boom of a telescopic crane or also the main boom of a mobile crane with a lattice boom, whereby, of course, the respective first boom section, ie the telescopic one Main boom or the lattice boom, can be extended at its end with at least one intermediate piece.
- a second boom section can then in turn be arranged, which can be rocked with the aid of a hydraulic unit arranged on the first or on the second boom section.
- Hydraulic unit are required. Due to the arrangement of a hydraulic unit at a great height proposed here, these lines can be dispensed with, so that this is an autonomous energy supply for feeding a piston-cylinder unit arranged at a great height or any hydraulic consumer such as a hydraulic motor.
- the hydraulic unit itself can be, for example, a hydraulic pump operated by an internal combustion engine, such as a diesel engine, for example, an electric motor could also be used to operate the hydraulic pump, but this would then again require a cable connection to the superstructure.
- an internal combustion engine such as a diesel engine
- an electric motor could also be used to operate the hydraulic pump, but this would then again require a cable connection to the superstructure.
- the present invention is intended, inter alia, to create a possibility of arranging at a great height
- bolting cylinders are provided at the foot of the main boom extension, which can be activated or deactivated with the aid of the hydraulic unit, in order to release or produce the bolts between the main boom extension and the main boom.
- the hydraulic unit is arranged on the second boom section, such as a luffing main boom extension.
- the arrangement of the hydraulic unit on the second boom section proves to be advantageous if one or more intermediate pieces are connected between the head of the main boom and a main boom extension, that even at the highest point of the first boom section, which in this case is at the head of the last intermediate piece ends, there is always a self-sufficient energy supply.
- the hydraulic unit does not have to be removed from the head of the main boom and then be reassembled on one of the intermediate pieces, but is always in the desired position due to the arrangement of the main boom extension.
- the hydraulic unit arranged on the main boom extension operates correctly when the main boom extension is rocking up and down, it is rotatably mounted about at least one axis so that it is in a substantially constant position relative to the ground during the entire rocking process.
- the pump of the hydraulic unit can run dry, which was already described as problematic at the beginning of the present application.
- a hydraulically actuable main boom extension which has an autonomous energy supply, such as a hydraulic unit.
- the main boom extension according to the invention with a hydraulic unit arranged thereon proves to be advantageous in that, since the main boom extension has its own power supply, no additional power supply lines have to be led from the superstructure of a crane to the main boom extension.
- the saving of these supply lines, which are usually to be provided, proves to be particularly advantageous if the main boom extension is not arranged directly on the main boom of a crane, but if one or more intermediate pieces are connected between the main boom extension and the main boom.
- the hydraulic lines normally to be provided in the area of the intermediate pieces can be omitted here, which enables the crane to be set up more quickly.
- main boom extension with its own self-sufficient energy supply is much more versatile and quick to use, since no additional lines for the hydraulic supply need to be laid to actuate the main boom extension, that is to say to move up and down.
- the main boom extension according to the invention can be set up very quickly on any main boom or on intermediate pieces arranged on it and can be tipped up and down immediately without additional hydraulic lines having to be laid.
- Fig. 1 is a view of a telescopic crane, with the crane boom shown in a lowered and in an erected position;
- FIG. 2 is a detailed view of the section Z marked in FIG. 1;
- FIG. 3 is a further detailed view of section Z of FIG. 1;
- FIG. 4 is a view corresponding to FIG. 1 of a telescopic crane with two intermediate pieces interposed between the main boom extension and the main boom;
- 5 a is a view of a mobile crawler crane with a two-part lattice boom
- Fig. 5b is a detailed view of the coupling area of the two lattice boom sections of Fig. 5a;
- 5c, 5d are further views of the mobile crawler crane of FIG. 5a;
- Fig. 6 shows a circuit diagram of the hydraulic supply.
- the main boom 1 shows a mobile crane, the jib 1, 2 of the mobile crane being shown in two different positions: a first stored position I and a second position II erected with the aid of a piston-cylinder unit 26.
- a first stored position I In the erected position II there is the telescopic main boom 1 in its fully telescoped state.
- the main boom 1 consists of a basic box 10 and a further six telescopic sections 5 through 9 that can be telescoped therein and telescoped.
- the main boom formed from the basic box 10 and the telescopic sections 4 through 9 is also used as the first boom section 1 referred to, but the first boom section 1 can also be the main boom of a lattice boom crane, as will be explained later.
- a main boom extension 2 is articulated on the head of the first boom section.
- the main boom extension 2 consists of a first box tip 14 and a lattice boom 15 which is articulated at the foot to the head of the first boom section 1.
- the main boom extension 2 consisting of the box tip 14 and the lattice boom 15, is also referred to as the second boom section 2.
- the second boom section 2 can of course also consist only of the lattice boom 15, for example.
- a lattice mast top can of course also be used.
- the second boom section 2 can be pivoted about the articulation point A in the luffing plane.
- the lifting cable 18 in a rocked-off position of the second boom section, it is guided from the superstructure 11 of the mobile crane to the tip of the second boom section 2 via a cable pulley 17 that can be folded up and down hydraulically.
- this cable pulley 17 can be dispensed with, since in the extended position the cable 18 runs straight from the superstructure 11 to the tip of the second boom section, without the need for deflection points.
- the cable pulley 17 can therefore be placed on the boom 1, 2.
- FIG. 2 shows the detail designated “Z” in FIG. 1 in the region of the articulation of the second boom section 2 at the head of the first boom section.
- the lattice boom 15 of the second boom section 2 is articulated to the head of the first boom section at position "A" with a hydraulically actuated bolting cylinder 28a.
- the lattice boom 15 is connected at a second point to the head of the first boom section, which is symmetrical to the luffing plane of the boom at the depth of the drawing plane.
- the two bolts can thus be located, for example, in the extension of the two lower chords at the foot of the second boom section. This bolting means that the second boom section 2 can be pivoted about the axis A, which is defined by these two bolting points.
- both boom sections 1, 2 can also be bolted to one another at point C with a hydraulically actuated bolting cylinder 28b.
- the hydraulic unit 19 is arranged inside the lattice boom.
- the hydraulic unit 19 can be of course also be arranged 'on the first boom section 1 and here in particular the head of the innermost telescopic section.
- Another space-saving possibility for arranging the hydraulic unit 19 can be, for example, to place the unit 19 in the innermost telescopic section 4.
- the hydraulic unit 19 is rotatably mounted about the axis "B".
- the hydraulic unit 19 could, for example, be a diesel unit with an associated hydraulic pump, it also being possible, of course, to use an electric motor instead of the diesel engine.
- the hydraulic unit 19 is connected to two piston-cylinder units 16 via a hydraulic line 22, only one piston-cylinder unit 16 being visible due to the view of the arrangement shown here.
- the second hydraulic line which is required to move the piston-cylinder unit in the opposite direction, is also not shown here.
- the head of the first boom section 1 is kinematically coupled to the foot of the second boom section 2 or the foot of the lattice boom 15 via the two piston-cylinder units 16.
- the cylinder of the respective piston-cylinder unit 16 is articulated on the upper side of the lattice boom 15 and the respectively associated cylinder on the head of the first boom section 1.
- a cable pulley 17 is arranged on the top of the lattice boom 15, which via a further piston-cylinder unit 21 by actuating the Hydraulic unit 19 can be applied to the top of the lattice boom 15.
- the hydraulic unit 19 serves primarily to actuate the first piston-cylinder units 16 in order to rock the second boom section 2 by extending the piston-cylinder units 16, as shown in FIG. 3. Furthermore, with the aid of the hydraulic unit 19, the second piston-cylinder unit 21 can be actuated via the hydraulic line 23 in order to put the foldable cable pulley 17 against the second boom section 2 or to fold it away therefrom.
- the second hydraulic line which is required for moving the piston-cylinder unit in the opposite direction, is also not shown here.
- the first boom section 1 is connected to the second boom section 2 via the hydraulically actuated bolting cylinders 28a, 28b.
- the bolting cylinders 28a, 28b are likewise supplied with the hydraulic unit 19, which provides the required hydraulic energy to the respective bolting cylinders via respective hydraulic hoses 29a to 29d.
- the second boom section 2 can of course also be folded out of the seesaw plane.
- Boom section 2 is produced in the axis A, so that the second boom section 2 can be rocked by actuating the piston-cylinder units 16 with the hydraulic unit.
- FIG. 4 shows a mobile crane which essentially corresponds to the mobile crane shown in FIG. 1, but two intermediate pieces 24, 25 bolted to one another are attached to the head of the innermost telescopic section 4 via a bolt connection.
- the intermediate pieces 24, 25 are two auxiliary boom parts manufactured in a lattice construction, which of course can also be produced in a box construction.
- a main boom extension 2 is articulated analogously to FIG. 1.
- the main boom extension 2 also consists of a first box tip 14 and a lattice boom 15, which is articulated at the foot to the head of the first boom section 1, which ends at the head of the second intermediate piece 25.
- FIG. 4 shows a mobile crane which essentially corresponds to the mobile crane shown in FIG. 1, but two intermediate pieces 24, 25 bolted to one another are attached to the head of the innermost telescopic section 4 via a bolt connection.
- the intermediate pieces 24, 25 are two auxiliary boom parts manufactured in a lattice construction, which of course can also be produced in a box construction
- a hydraulic unit 19 is arranged according to the invention, which has a first piston-cylinder unit 16, which is arranged between the head of the first boom section 1 and the foot of the second boom section 2, with hydraulic Feeds energy.
- the second boom section 2 can also be pivoted about the axis A by actuating the hydraulic unit 19. 1 to 3, the hydraulic unit is also shown as being arranged on the second boom section, but this can also be done here
- Hydraulic unit 19 can of course be arranged at the end of the first boom section 2, for example at the head of the second intermediate piece 25.
- the arrangement of the hydraulic unit 19 on the second boom section 2 proves to be advantageous, however, since this can reduce the set-up effort in order to convert the mobile crane shown in FIG. 1 to the one shown in FIG. 2 by installing two intermediate pieces 24, 25.
- the hydraulic unit 19 is arranged on the second boom section, only the second boom section including the cob cylinder unit 16 has to be removed for the conversion, the intermediate pieces 24, 25 have to be attached and then the second boom section including the cob cylinder unit 16 has to be articulated again.
- a separate dismantling of the hydraulic unit 19 from the head of the innermost telescopic section 4 and subsequent reassembly at the head of the second intermediate piece 25 can thus be omitted.
- 5a to 5d show various positions of a crawler crane with a two-part lattice boom 1, 2, the two boom sections 1, 2 of which are kinematically coupled to one another using a hydraulic unit 19 and a piston-cylinder unit 16.
- the entire two-part lattice boom of the crawler crane is in one on the ground stored position.
- the second boom section 2 is first erected by actuating the piston-cylinder unit by the hydraulic unit 19.
- Cantilever section 1 in an axis A on the upper chord of the two cantilever sections 1, 2 bolted.
- a first piston-cylinder unit 16 is arranged between the two lower chords of the two boom sections 1, 2, the piston of which is articulated on the first boom section and the associated cylinder of which is articulated on the second boom section.
- a hydraulic unit 19 is attached to the head of the first boom section in an articulated manner and is suitable for supplying the first piston-cylinder unit 16 with hydraulic energy.
- the hydraulic unit 19 is shown arranged on the first boom section in FIG. 5b, the hydraulic unit 19 can of course also be arranged on the foot of the second boom section. This would even prove to be more advantageous in the present case, since it could make the length of the hydraulic hose 22 for feeding the piston-cylinder unit 16 of the piston-cylinder unit 16 shorter.
- the second boom section 2 was moved with the aid of the hydraulic unit 19 and the piston-cylinder unit 16 from the position on the ground shown in FIG. 5a to the almost vertical position shown here.
- the first boom section 1 is erected over the neck cable 27, as can be seen in FIG. 5d.
- the second boom section 2 is lowered again relative to the first boom section 1, so that in the end position the head of the first boom section 1 can ultimately be bolted to the foot of the second boom section 2.
- the hydraulic unit 19 can of course also be used here to actuate the corresponding bolting cylinders for bolting the two boom sections 1, 2.
- FIG. 6 finally shows an example of a possible hydraulic system which schematically shows the supply to the hydraulic consumers 16, 19, 28a to 28d.
- the hydraulic system shown has a neutral circulation, which means that the hydraulic unit 19 conveys the hydraulic fluid to the tank 33 almost without pressure when the valves 30 and 34 are not actuated.
- the connection to the tank 33 is interrupted, so that, depending on the switching position of the valves 30, 34, the hydraulic consumers 16, 21 or 28a-28d are supplied with hydraulic fluid on the bottom or rod side of the cylinders ,
- the resulting pressure depends on the load on the respective consumers 16, 21 or 28. However, at most only a pressure can be set which corresponds to the pressure set at the pressure limiting valve 31.
- the hydraulic consumers 16, 21 are equipped with load holding valves 32 which serve to secure the position of the hydraulic consumers 16, 21 even when the system is switched off or in the event of a line break.
- the load holding valves 32 can be unlocked hydraulically, which can be done, for example, by direct control via the valve 34 or by a separate control oil line 35.
- FIG. 6 Only one possible hydraulic system is shown in FIG. 6, the usual comfort and safety devices, such as variable throttles or filtering, for simplification, which the person skilled in the art knows how to implement accordingly, are not shown.
