Description

EXEMPLARY EMBODIMENT

(1) An exemplary embodiment of the invention is represented in the drawing and is explained in more detail below with reference to the figures, of which.

(2) FIG. 1 schematically shows in section a hydraulic unit of a climbing device according to the invention for adjusting and/or climbing a scaffolding and/or a formwork and/or a platform,

(3) FIG. 2 schematically shows a perspective view of the hydraulic unit according to the invention in FIG. 1,

(4) FIG. 3 schematically shows a hydraulic unit on a climbing rail in two different operating states of a climbing device according to the invention for adjusting and/or climbing a scaffolding and/or a formwork and/or a platform and

(5) FIG. 4 schematically shows a topology or interconnection of multiple hydraulic units as represented by n and a separate central unit of a climbing device according to the invention.

(6) FIG. 1 schematically represents a hydraulic unit 1 of a climbing device for adjusting and/or climbing a scaffolding not shown in further detail, and/or a formwork and/or a platform according to the invention. The hydraulic unit 1 comprises a hydraulic cylinder 2, an electric motor a hydraulic pump 4 and a hydraulic tank 5 for storing hydraulic fluid/oil. The electric motor-powered pump 4 furthermore comprises a control block 6.

(7) In addition the hydraulic unit 1 comprises an electronics unit 7 or control unit, particularly for controlling/regulating and monitoring the electric motor 3 and/or a sensor 11 and/or a display/signal light 9. The sensor 11 preferably takes the form of a position sensor 11 and is arranged in the hydraulic cylinder 2 or in the cylinder housing 12, in order to detect an adjustment or an extension/retraction of a piston 10 and to transmit signals/data, among other things to the electronics 7.

(8) The hydraulic unit 1 furthermore comprises a housing 13, in which the aforementioned components are arranged and protected. In this case it is embodied as a closed housing shell, so that the components/elements arranged/integrated herein are protected from dirt and/or damage etc. The hydraulic unit 1 can therefore be carried as an integral module by one person, preferably by means of two carrying handles 17.

(9) However, a hydraulic unit 1 or hydraulic units 1 when more than one hydraulic unit is deployed according to the invention is/are of comparatively large and heavy dimensions can also be designed/used as integral modules, which are two heavy for one person, so that these large/heavy hydraulic units 1 preferably have to be transported by a lifting device such as an elevator, lifting platform, crane or the like, particularly between the construction sections, floors of the building, platforms of the scaffolding, etc.

(10) The hydraulic unit 1 therefore comprises hydraulic components/actuators/sensors on the one hand and electrical/electronic components/actuators/sensors on the other, so that here the hydraulic unit 1 may also be referred to as a hybrid cylinder. This means that in the hydraulic unit 1 according to the invention two technologies are combined with one another, that is to say here the hydraulics and the electrics/electronics.

(11) The hydraulic unit 1 furthermore comprises multiple electrical plugs or connectors 8 or plug-and-socket connectors 4 8a, which ensure the electrical power supply to the hydraulic unit 1. For example, multiple connectors 8 are provided, on the one hand for the power supply of the electric motor 3 and/or the electronics 7 and on the other for relaying power to a second hydraulic unit 1 (cf. FIG. 4).

(12) In addition, separate electrical connectors or the like may also be provided in order to form an electrical/electronic network or a digital bus system/network. This interlinking of multiple hydraulic units 1 may accordingly comprise any number of hydraulic units 1 as represented schematically in FIG. 4. The hydraulic units 1 here may be connected to one another/interconnected by means of electrical connecting cables 20 for the power supply and/or for the data/information transmission and/or connected to a separate, central control unit 19. The data/information transmission in particular may also be achieved wirelessly or by means of transmitters and receivers.

(13) Climbing scaffoldings or rail climbing systems have long been used, so that a comprehensive representation and description of the climbing device according to the invention with all components and their operating principles or interaction/operating sequences are largely dispensed with, since the principles of these are known to the person skilled in the art.

(14) Here only one hydraulic unit 1 according to the invention and its arrangement in FIG. 3 is illustrated in a first operative state 1a (FIG. 3a) and a second operative state 1b (FIG. 3b) as will be described in somewhat more detail. FIG. 3 represents two climbing shoes 15, 16, which are coupled to a climbing rail 14 in a known manner. The climbing shoes 15, 16 can be displaced/moved along the climbing rail 14, so that the hydraulic unit 1 is guided on/by the climbing rail 14. The climbing shoe 15, 16 has a detent system known to the person skilled in the art, by which its direction of movement is predefined. A travel/displacement in the opposite direction is not possible without influencing the climbing shoes 15, 16.

(15) A support shoe 17 couples a scaffolding/platform, not further defined, or the like to the climbing rail 14. The climbing operation is illustrated by comparing the two FIGS. 3a) and 3b). In FIG. 3a) a rod side of a cylinder 2 (see FIG. 1) is supplied with hydraulic fluid/oil or pressurized by way of the hydraulic unit 1. The climbing shoe 15 prevents a downward movement, and therefore the climbing shoe 16 traverses in the direction of the cylinder 2.

(16) In FIG. 3b) a bottom side of the cylinder 2 is supplied with oil by way of the hydraulic unit 1. The climbing shoe 16 prevents a downward movement, and therefore the climbing shoe 15 and the support shoe 17 traverse around the cylinder length. A climbing step is therefore completed. The operating states according to FIGS. 3a) and 3b) are repeated until the desired position the of the platform or the like, not further represented, is reached.

(17) In general terms the following may be highlighted as particular advantages of the hydraulic unit 1 according to the invention:

(18) 1. Each hybrid cylinder or hydraulic unit 1 is a self-contained working unit.

(19) 2. Each hybrid cylinder or hydraulic unit 1 has a so-called oil filling for life.

(20) 3. No opening of the (closed) hydraulic circuit of the hydraulic unit 1 is necessary.

(21) 4. No aging and replacement of hydraulic hoses (service life max. 6 years).

(22) 5. Travel measurement in the hybrid cylinder or hydraulic unit 1 allows an absolute synchronization of all hydraulic units 1 or hybrid cylinders.

(23) 6. No calibration necessary (offset and/or staggered travel possible in the synchronization)

(24) 7. Individual hybrid cylinders or hydraulic units 1 or in the complete network can be run with synchronization.

(25) 8. Any number of hybrid cylinders or hydraulic units 1 can be coupled (if necessary by multiple central units 19), for example 16-32-64 items or hydraulic units 1

(26) 9. Odd numbers of hybrid cylinders also possible for example 1-3-5-7 items or hydraulic units 1.

(27) 10. No power loss of the thrust force due to hydraulic flow resistances, for example through flow dividers, flow regulators etc.

(28) 11. No power loss of the thrust force due to long hose lines.

(29) 12. Negotiation of ramps (soft starting, variations in steepness/length etc.) possible.

(30) 13. Interconnection of the hybrid cylinders or hydraulic units 1 only by electrical cables.

(31) 14. (Sense/electronic/electrical) cut-off in the event of Overload.

(32) 15. Overload control electrically adjustable.

(33) 16. Diagnostic facilities and display of the system status for example by Interlink.
