FIELD AN~ BACKGROUN~ F THE INVENTION
This invention is directed to a cable hoist or puller device with drive motor, clutch, transmission and cable drive pulley.
Motor-driven small-sized hoists are known which serve mainly for vertical movement of ~oads and which conse~uently are only o~ limited use. This also is true of electric hoists or winches and elevating mechanisms with a e5 j r ~
cable drum and pocaibly ~n additional brake.
jl The known motor-driven elevating mechinisms are ~requently built so as to occupy a great deal of space and are , di~ficult to handle because o~ their heavy weight.
I Combined use, for instance as an elevating mechanism o~ a cable drive and a drum drive is impossible.
This, the invention attempts to rQmedy.
:, .
., The present disclosure is of A portable cable hoist of the type described above, ¦ which is distinguished by compact construc~ion and low weight. Furthermore, the new hoist has a high tractive ~orce, high cable speeds is easily handied and can be used as a hoisting mechanism, as well as a cable drive or cable railway drive and drum drive.
~ 36~iS~ , The cable hoist described uses a clutch designed as a manually operable multiple disk clutch or disk brake and a planetary gear train transmission.The disk clutch i~ arranged on the output sha~t of the driven planetery gear train, and a drive pinion for the cable drive pulley is connected on the output side o~
the disX~clutch between the planetary gear train and the multiple disk clutch. The cable drive pulley is cantiliver supported and has a 'I ring gear meshing with the drive pin'ion. In , a preferred embodiment o~ the invention, a multiple braXe is ¦¦ actuated by means o~ a hand crank as a regulatable lowering bra~e with disengageable contact pressure ¦ eleme~ts, ~or instance cup springs.
i!
Il I
, These fieatures o~ the invention permit loads to be B lowered with the cable hoist under their ~ weight and ~~
regulated braking ~orce. ~n especially accurately regulatable braking sy~tem is realized with the mUltipls disk brakeis, sinae the load can be lowered or li~ted in a sensitiVe and acaurate manner so that ~or instance the insertion o~ bolts and screws, machine partS or the like can be accomplished with the precision o~
millimeters. I~ the drive motor is such that it cannotexert ¦ any braking effect (gasoline, compressed air) the fs~a~tel ¦ carrierwith the incorporated blocking latohc_ serve as a ~ //~i~
reversingblockage, which ~ff~ rotary motion only when the hoistis lifting. As soon as the power output shaft 12~6~5~
of the planetary gear train moves in the opposite direction, the pawls snap into a hollow wheel in a positively locking manner and block the drive system, which for lowering purposes can then only be released in effect by the multiple disk clutch. The p1anetary gear train achieves a very high step-down or velocity ratio. This applies particularly if, the drive motor drives the planetary gear train drive through a V-belt reduction unit, if desired also with interposition of a reducer gear unit. An internal combustion engine is preferred as the drive motor, however, the use of a compressed air motor or an electEic motor is also possible. The over-all step-down or velocity ratio can amount to approximately 1 to 600. The combination of the planetary gear train, which is light in weight, with the multiple disk clutch assures high efficiency with minimal frictional resistance, so that the cable hoist can operate trouble free, with high tractive power, high cable speed and low overall weight even at considerable altitudes above sea level.
Consequently, the invention is particularly suited for cable railroad-steel construction and use by avalanche control personnel. The cantilever supported cable drive pulley allows for the use of an endless spliced cable and consequently use of the hoist not only as an elevating mechanism, but also as a cable or cable railway drive. In practice, an endless spliced cable can be connected at an arbitrary position onto the cable drive pulley, without the cable having to be thinned, the cable ends having to be threaded into the drum or the cable hoist B
~665~
having to be disassembled. Furthermore, a particularly compact construction is achieved by the arrangement of the planetary gear train, multip]e disk clutch and cable drive pulley, which can be further optimized by supporting a hollow shaft with the drive pinion for the cable drive pulley and connected to the output side of the multiple disk clutch on the drive shaft of the planetary gear train. A cable guide roller and a pivotably supported cable contact pressure roller engaging into the cable groove of the cable drive pulley can also be used with the cable drive pulley, which contact pressure roller operates --proportionally to the traction or tension in the cable. This simultaneously achieves a secure transmission of the drive or tractive force to the cable.
The cable drive pulley can incorporate plug-in bores for the blocking bolts and a plug-in clutch for driving any other desired apparatus or installation. The thus driven appliances or installation can be blocked when stationary, or can be made to draw against their load by increasing the torque transmitted by the multiple disk clutch or can be released in the direction of the load by reducing the torque transmitted by the clutch. In this manner the cable hoist can be used, for instance, as a bobbin- or reel-drive or drum drive, because the drum involved can be driven by a drive chain through a sprocket wheel at the plug-in clutch. The drum can be provided with an appropriate ring gear for this purpose. The new cable hoist enables direct drive of large bobbins, reels or drums or with 3fi65~
the interposition of an additional chain drive, while the cable hoist has a dead weight of less than 30 kg. As a result, the function as a reel- or bobbin-drive is also combined with the function as an elevating mechanism and cable or cable railroad drive.
The planetary gear train, the multiple disk clutch and the cable drive pulley are supported in a housing. A housing cover for the cable drive pulley is supported on the clutch housing so as to be axially displaceable. The housing can thus be easily opened for placing an endless cable on the cable drive pulley. The housing cover can be designed as a cable derailment guard and thus to incorporate on its inside guides, sliding blocks and rollers for instance of plastics material, distributed across a partial circumference of the cable drive pulley, so that the cable cannot leave or jump out of the cable groove in the pulley.
In a modified embodiment of the invention it is possible to dispense with the multiple disk clutch if an electric motor with a magnetic brake is used as the drive motor. In that instance no hand crank is required, since the electric motor operates in both rotational directions. The lowering of the lifting of a 1~665~
load then occurs electrically by reversing the direction of the motor. Finally a single point suspension or anchor is provided in the new cable hoist, so that it can operate in any position. Because of the single point anchoring the machine adju~ts itself automatically to the direction of the force exerted.
A cable hoist is therefore realized which can be used as a portable appliance because of its low weight and easy handling. Nevertheless, the transmission of high tractiv~ ~orces at high cable speeds is assured.
Equally~ accurate lowering and raising of loads is made possiblQ. In addition a universal drive for cables, cable reels, rope reels and other appliances to be driven, is realized. ~hus, thQ cable hoist can, for instance, be used in high rise construction as well as in tho construction of cable railways or masts, in reinforced concrete construction, bridge construction and in all elevating and -tractive operations. Utilization o~ the cable hoist is also conceivable in life~saving operations and in forestry (hoisting of individuals and loads, raising of capsized vehicles, removal of trees, trunks and pieces of rock, etc.). The same applies for the construction of protective structuresagainst avalanches and for engineering types of construction. Even in the construction of cable channels or trenches, the cable hoist described is suitable for laying lines, cables, pipe elements, etc. Finally, the ~ 2~665~
novel cable hoist functions as a retrieval winch for instance for heavy duty vehicles or as an assembly appliance for military engineering units.
More particularly, in accordance with the invention there is provided a cable hoist comprising:
a housing;
a drive motor mountecl to said ~ousing and having a motor output:
a planetary gear train having an input connected to said motor output, and a planetary gear train output;
hand operated multiple disk clutch means having an.input connected to said planetary gear txain output,.and a clutch means output:
a drive pinion connected to said clutch means output and positioned between said planetary gear train and said clutch means; and a cable drive pulley mounted for rotation in cantilever fashion to said housing, said cable drive pulley having a ring g¢ar mashed with said drive pinion for rotation of said cable drive pulley with operation of said drive motor through said planetary gear train and said hand operated multiple disk clutch means.

The multiple disk clutch 3 is actuated by means of a hand crank 10 as a regulatable lowering brake for the suspended load with interposition of unloadable contact pressure elements 9, for instance cup springs. The suspended load can conversely also be lifted. The drive motor 2 drives the planetary gear train 4 through a V-belt step-down unit 11 and,if desired, with interposition of a ~.2~6~5~
reduction gear 12. The overa:L1 s-tep down ratio can amount to approxlmately 1 to 600.
