Definitions
- the present invention generally relates to equipping an auxiliary hoist on a mobile crane.
- it is concerned with a mobile crane auxiliary hoist setting system and a method of setting up a mobile crane auxiliary hoist;
- a foot support for a mobile crane auxiliary hoist is disclosed.
- auxiliary hoists to complement or support the main hoists is known in mobile crane construction.
- auxiliary hoists are provided for specific purposes as separate units to equip and deploy them on the crane when needed.
- hoists on Hinstbefest Trenten which are usually arranged on their frame parts and serve to attach the Hilfsshubtechnikes on the crane.
- the object of the present invention to provide a set-up system and a method for setting up a mobile crane auxiliary hoist, which improves the set-up of such an auxiliary hoist Shape the way.
- the setup should be possible with a manageable work, time and attention.
- the setup system according to the present invention having auxiliary hoist truss attachments associated with the auxiliary hoist frame and for attachment of the auxiliary hoist to the crane has a scaffolding which can place the auxiliary hoist frame and / or the setup fixtures in a set-up position.
- the set-up system according to the present invention is provided with its own mounting equipment which is capable of moving the necessary parts of the auxiliary hoist or the auxiliary hoist itself or to bring into a position that allows the execution of the set-up process or makes possible.
- the scaffolding could be considered in this sense as a movement or adjusting device for the Hilfsshubwerkrahmen or the Hinstbefest Trenten.
- the scaffolding according to the invention supports the setup process in such a way that it can be performed much less expensive and labor-intensive, in many cases even automatically or semi-automatically.
- the counterbalance lifting system no longer has to be misused for the auxiliary hoist setup or adapted for this task.
- the auxiliary hoist set-up operation can be carried out quickly, and because that, in particular automatic or semi-automatic, retrofittable, will always perform the same, correct actions, also in a very safe manner.
- the setup position may be a mounting position on the crane superstructure, in which an engagement between the auxiliary hoist setup fixtures and countermounts takes place, which are arranged on the crane uppercarriage, in particular on the main lifting gear.
- the setup position at any suitable location on the mobile crane, where it makes sense depending on the crane design to fix the auxiliary hoist.
- the scaffolding can work in different ways and direction, or act, for example, move the auxiliary hoist frame and / or the setup fixtures in the setup position, move or offset, in particular up, down, obliquely up or down or sideways ,
- various drive or actuation types are conceivable, namely, for example, electrically, hydraulically, pneumatically or in a combination
- mechanical drives in each of the mentioned drive forms play a role or can be used separately or alone.
- manually operated mechanical drives such as, for example, crank drives or toothed gears can also be used. It is important that the set-up process always takes place in a comprehensible manner in a reproducible manner, as is in particular also expressed by the term "armor".
- the scaffolding includes a hydraulic lifting cylinder device that raises or lifts the auxiliary hoist frame from a substructure.
- a sub-element may be part of the auxiliary hoist unit.
- the auxiliary hoist and its armor advantageously form one unit, i. a separate or individual or separable component.
- the substructure element is a supporting base or base plate, which is assigned to the frame, in particular via the scaffolding or the lifting cylinder device, from which the frame can be lifted away into the set-up position by means of the scaffolding or the lifting cylinder device.
- the sub-element may be the part that comes to rest on the corresponding crane part and is designed to fit while the scaffolding lifts the rest of the auxiliary hoist away from that substructure into the setup position.
- the armor or the Lifting cylinder device flameproof, especially tensile and pressure resistant, to connect to the support base or base plate. In the latter case (tensile and pressure-resistant), the frame can not only be pushed away from the substructure, but can also be pulled back to the frame after the setup process, the substructure, so that the auxiliary hoist is free of its mounting position.
- a plurality of feet are arranged on the underside or the side facing away from the frame of the support base or base plate, in particular positionally adjustable and / or position-compensating feet.
- feet can also be placed directly on the lower part of the framework, e.g. in the case where there is no support base or base plate under the scaffolding.
- foot counter-bearings are provided on the substructure, in particular on the counterweight rest or on the mounting frame, complementary to the feet of the support base or base plate, in particular foot retainers.
- feet or a footrest for a mobile crane auxiliary hoist have already been addressed in some places.
- a foot support is disclosed herein individually, that is, as a device that establishes an inventive unit individually, but it may also form part of a set-up system or a set-up system, as they do will be described in detail above and in particular later.
- the foot support has a downwardly projecting foot bearing element which is arranged in a limited mobility and / or adjustable in at least one direction relative to the auxiliary hoist.
- Such relative to the auxiliary hoist there are already increased possible tolerances for this direction, both during production and during installation of the auxiliary hoist on its substructure.
- a movable arrangement in this sense comprises both one-way adjustability and movability, which can be achieved by design measures but also by material choice.
- the coupled largerelement be configured elastically deformable, in particular perpendicular to its longitudinal axis or transversely to its attachment, so that a mobility is given in two axes perpendicular to the longitudinal axis.
- Another or additional possibility is to equip the the contemplatlagerelement the auxiliary hoist or on its support base or base plate with an adjustable along the feasibleelement longitudinal axis or in the direction of its attachment, lockable storage, which can be a lockable screw-threaded connection.
- Such a connection makes a simple height adjustment possible.
- a mobility or adjustability of the contemplatlagerelements can reduce manufacturing costs, because the tolerances to be complied with for the components can be increased.
- the cutting work is reduced.
- Even for adjacent components large manufacturing tolerances can be compensated, for example, when using Gussplatten-receiving holes and in particular during the setup process in the event that a cast plate (substructure) is not stored centrally. Because the recording points can be made larger and are more visible to the crane operator, the set-up can be done faster, and with sufficient space can auxiliary support structures partially or completely omitted, such as the above-mentioned Spitzdornkonstruktionen.
- auxiliary hoist In the inventive method for equipping a mobile crane auxiliary hoist with auxiliary hoist attachment, which are associated with the framework of the auxiliary hoist and serve to attach the auxiliary hoist on the crane, the auxiliary hoist or its auxiliary hoist frame and / or the Jostbefest toen be moved to a set-up, proceed or offset.
- the movement, the process or the offset by a mounted on the auxiliary hoist scaffolding which brings the Hilfssubtechnik frame and / or the Studstbefest onlyen in the setup position.
- the method according to the invention again has those advantages and optional features which have already been described above with reference to the set-up system or the setup system.
- a set-up system, a set-up installation or a foot storage can be used or used, as described above or in detail later.
- FIGS. 1 to 4 An embodiment of a mobile crane auxiliary hoist, which is configured according to the invention with a framework, is in the FIGS. 1 to 4 to see.
- the FIG. 1 shows an oblique, perspective view from top left, the FIG. 2 a top view that FIG. 3 a side view and the FIG. 4 a front view.
- the auxiliary hoist 10 has a steel frame 14 in which a winch 12 is rotatably mounted.
- a winch 12 is rotatably mounted on a front page, in the FIG. 4 serves as a view page, the connection piece 36 protrudes for the winch 12 out of the frame 14.
- the auxiliary hoist 10 also includes three other assemblies, namely the assembly of the setup fixtures, the assembly of the framework and the predominantly largerungs assembly.
- the setup fixtures With the setup fixtures, the auxiliary hoist on the crane superstructure, e.g. attached to the main hitch, while the framework can bring in the frame with the setup fixtures in a setup position.
- the auxiliary hoist itself, only its frame, or even just the set-up fixtures, can be moved with the scaffolding so that the set-up position is achieved. But it can also be a combination of these components are moved, as is the case in the present example.
- the truss fixtures with which the auxiliary hoist of the FIGS. 1 to 4 is secured in its working position located on the side of the hoist 10, which in the FIGS. 1 and 3 can be seen from diagonally front or front. They are bilateral and mirror-inverted mounted at the edges and have a projection on top 18, which holds a bolt 16 from two sides. On the underside, in turn, a double projection 20 is formed, which forms a gap 22, in which a bolt 26 can retract from the piston-cylinder unit 24.
- the bolts 16 and 26 are, as already mentioned, the attachment of the auxiliary hoist frame 10 to the crane superstructure or to the main hoist, as will be explained in more detail later.
- the second, functionally essential assembly of the hoist 10 is the scaffolding, which is capable of lifting the hoist 10 on its frame 14 and bring in a set-up position in which the bolts 16 and 26 form a mounting engagement.
- the piston-cylinder unit which is arranged on each end face on the frame 10, wherein the cylinder has the reference numeral 32 and the piston has been given the reference numeral 40. While the cylinder is above the side plate 34 (FIG. FIG. 1 ) is attached to the frame 10, the piston 40 has via its end piece 38 an attachment to the base plate 28, which in the FIGS. 1 and 4 is clearly visible.
- the third assembly of Hilfshubwerks 10, in the FIGS. 1 to 4 becomes apparent, is the subjectlagerung, here with in the FIGS. 1, 3 and 4 apparent feet 30 is realized.
- the satisfiedlagerung and the feet 30 are also described in more detail; they have a downwardly conically tapered and made of an elastic material foot bearing element that can be particularly easily used in an abutment and thereby allows large tolerances and positioning inaccuracies or compensates.
- the feet 30 are disposed at the bottom of the (four) corners of the base plate 28; they are shown explicitly on the front page.
- auxiliary hoist is used in this example to prepare for the setup process on the in FIG. 5 apparent counterweight package 44 set up.
- the counterweight package 44 rests on the crane undercarriage 42 of a mobile crane, and the uppermost counterweight with the trained as a round, concave recesses foot receptacles 48 is used as a substructure for the setup process.
- FIG. 6 shows how an auxiliary hoist 10 has been placed on the top counterweight plate 46 in preparation for the set-up process so that the here barely visible feet have been introduced into the foot receptacles 48.
- the same state is in an oblique view from the opposite side in FIG. 7 represented, where the previously mentioned foot 30 is indicated in its footrest with a reference numeral.
- the direction "forward" relative to the crane undercarriage 42 goes in the FIG. 6 to the left and up in the FIG. 7 to the right diagonally downwards, so that it can be said that the auxiliary hoist 10 with its setup fastenings 16, 18, 20, 24 is parked on the crane forwardly aligned on the uppermost counterweight element 46.
- the further setup process is the FIG. 8 to withdraw, the view direction again that of Figures 5 and 6 equivalent.
- the auxiliary hoist 10 still on the top counterweight element 46 as it is in the FIGS. 6 and 7 has been shown. But it has the crane-superstructure 48 with the hoist bracket 50 to which the main lift 52 is attached, screwed backwards so that it is straight forward and backward over the crane undercarriage 42 is.
- the Haupthubwerk 52 comes in one Position in which the auxiliary lifting counter-attachments 54 and 56 attached to it just come to rest freely above the set-up fixtures 16, 18, and 20.
- the counter-attachments 54 and 56 include upper hook members 54 mounted on both sides and attached on both sides catching and centering tabs 56.
- the piston-cylinder unit with the cylinder 32, so the scaffolding, still fully retracted, so that the frame 10 sits tightly over the plate 28.
- the skeleton is operated to perform attachment of the auxiliary hoist 10 to the main hoist 52, and the state after this step is in the FIG. 9 shown.
- the piston 40 of the framework has been extended out of the cylinder 32 and has raised the frame of the auxiliary hoist 10 from the base plate 28 upwards.
- the bolt 16 (between its bearings 18) retracted into the hook 54 on the upper rear side of the Haupthubtechniks 52, on the other hand, the projection 20 with initially not triggered bolt 26 in the catching and centering tab 56 on the lower side captured on both sides.
- the bolt 26 can then be retracted by means of the piston / cylinder unit 24 in the intermediate space 22 (see, eg FIG. 1 ), and a centered, fixed bolt connection has been achieved on the underside between main lift 52 and auxiliary hoist 10.
- the fasteners 16, 18 and 54 ensure on the top of both sides for the tilting safety.
- FIG. 11 If it is necessary to attach the counterweight to the crane superstructure, still how to fix the FIG. 11 can take the piston-cylinder unit 58 are used, which engages with its attachment 60 in the counterweight package and raise it altogether. In this case, the auxiliary hoist 10 comes to rest in its foot storage and the entire counterweight package can be transported with the hoists on the superstructure.
- FIGS. 12 to 14 Another embodiment of the present invention is shown in FIGS. 12 to 14 shown.
- the auxiliary hoist 10 should be placed at a certain height on the crane undercarriage 42, so that the main lift 52 moved up and the auxiliary hoist can be moved by lifting it with the scaffolding in its coupled setup position.
- the height of the parking was the height of the top counterweight element, but there may be cases where fewer or no counterweights are prepared.
- a mounting frame can be provided as shown in FIG FIG. 12 has been shown and provided with the reference numeral 64.
- the mounting frame 64 rests with its two columns 66 on the counterweight tray 62, and it carries the frame 68, in the above four foot receptacles 70 are introduced, which are similar in arrangement and design of the foot 48, the example in the FIG. 5 you can see.
- FIG. 13 shows how a Hilfssubtechnik 10 can be placed on the mounting frame 46 accordingly, and thus already the preparation for the setup process is done, which then takes place in a corresponding embodiment exactly as in the FIGS. 8 to 10 is shown, wherein the mounting frame 64 takes over the function of the uppermost counterweight plate 46 as a footprint for the Hilfsshubwerk 10.
- the embodiment with the mounting frame not only works without counterweights, but also when a number of counterweights 72 are prepared, these counterweights have recesses 74 for the passage of the column 66.
- FIG. 15 shows here a quarter-cut view of a broadband source, while a half-cut view of the FIG. 16 is removable.
- the foot 30 is fixed to a corner of the base plate 28, wherein its providedlagerelement 92 comes to lie in the recess or foot 48 of a counterweight plate 46.
- the subjectlagerelement 92 is made of an elastically deformable material, and this can be compensated for relatively large manufacturing tolerances, and it takes place at the onset of automatic centering when the convex cone-shaped Withlagerelement 92 enters the concave, correspondingly reverse foot receptacle 48. Because of the relatively large diameter of the consideredlagerelements 92 and the foot 48 shots the setup process or the erection of the auxiliary hoist can be done quickly, also because the mounting points for the crane operator are clearly visible.
- the satisfiedlagerelement 92 which can be configured as a special rubber spring element, ensures in the horizontal direction for an automatic compensation of positioning inaccuracies and for a radial play compensation.
- the aforesaid horizontal adjustability resulting from the elasticity of the foot support member 92 acts mainly perpendicular to the longitudinal axis of the foot attachment defined by the bolt 82.
- the bolt 82 is a bolt which is centered with its head centered over a disk 84 in a bushing consisting of an upper half 86 and a lower half 88 and comprising the base plate 28 on both sides. Below the lower sleeve half 88, the bolt 82 passes through another washer 90 into the foot support member 92, thereby holding it in threaded engagement.
- the disc 90 is fixedly connected to the elastic material of the contemplatlagerelements 92 - it is made of a metallic material and carries an internal thread, which engages with the external thread of the bolt 82 in the lower region.
- twisting the bolt 82 causes the distance between the foot support member 92 and the base plate 28 to increase or decrease such that the foot 30 can be lowered or raised as viewed from the base plate 28.
