Definitions
- the present invention relates to a cable lifting apparatus, which provides essential novelty characteristics and notable advantages over known systems and used for the same purposes in the current state of the art.
- the invention refers to a cable lifting apparatus comprising one or more drive pulleys and one or several continuous cables
- the field of application of the invention is obviously within the industrial sector dedicated to the design, manufacture and assembly of lifting devices, in general both for lifting loads and for lifting people.
- the present invention is intended for the realization of a cable lifting apparatus in which the pressure exerted on the cable depends, as in the case cited in the last document, on the load to be lifted, but with the
- SUBSTITUTE SHEET (RULE 26) particularity that is affected by two differentiated factors.
- the first factor is provided directly by the load to be lifted, while the second factor is derived from the tangential reaction of the drive pinion mounted at the outlet of the reducer, which meshes with a crown integral with the traction sheave.
- the effect of tightening the rollers on the suspension cable is achieved thanks to the provision of a rotating box containing the gears and the drive pulley.
- Figure 1 is a schematic view comprising two representations (a) and (b) illustrative of the principle of operation of the lifting apparatus of the present invention
- Figure 2 illustrates a top plan view of an embodiment of the apparatus of the invention, in its version of a single drive pulley and a respective suspension cable;
- FIG 3 illustrates a side elevation view of the same apparatus shown in Figure 2
- Figure 4 is an illustrative schematic representation of an exemplary embodiment of a hoisting apparatus according to the invention, in its slotted pulley version and use of two suspension cables.
- SUBSTITUTE SHEET (RULE 26) illustrative of the operating principles of the apparatus of the invention.
- an extended suspension cable 1 is seen so that it passes through the peripheral throat made in a drive pulley 2 that incorporates a wheel 3 joined to a lateral surface thereof, in relation to concentric with respect to the axis of rotation of said pulley 2.
- a pinion 6 is engaged with said cogwheel 3, being maintained in its operative position by means of a connecting rod 5 that extends between the axis of rotation 8 common for said pulley 2 and wheel associated toothed 3, and the axis of rotation of the pinion 6 keeping its relative distance constant, this assembly being pivotable with respect to the axis of the pinion.
- the last axis of rotation mentioned that is, the axis on which said pinion 6 is mounted, is the same on which the driving group consisting of a motor, a brake, a centrifugal brake and a reducer is mounted.
- the cable tightening roller assembly has been schematized by a wheel 4, and the arrow Fi materializes the pressure exerted by said tightening rollers 4 on the portion of the suspension cable 1 that is housed in the peripheral throat of the pulley 2 and whose suspension is exercised according to arrow F 2 , while the section of loose cable is represented behind the position of the rollers 4 and has been indicated with the numerical reference la.
- SUBSTITUTE SHEET desired by virtue of the contact between said pulley 2 and the cable 1, as expressed graphically by the arrows F 3 shown only by way of illustration in the same Figure 1, representation (b). It is evident that the balance of forces requires that the normal force created between rollers and cable be a function of the total load (cable tension) and of the distances to the pivot point of the pivoting assembly. In this way it is achieved that the radial load on the cable is proportional to the total load to be lifted.
- the force exerted by the pressure rollers can be modulated, adjusting it with great precision to its optimum value both from the point of view of unwanted absence of sliding, and from the point of view of a greater longevity of the cable.
- the pulley 2 can be made so as to incorporate several grooves or throats, a set of independent pressure rollers 4 being arranged for each of the cables associated with each of the respective throats. Consequently, this modified version of the apparatus described above consists solely of repeating the execution for a cable already presented, as many times as cables it is desired to use.
- SUBSTITUTE SHEET (RULE 26) similar, the assembly being made such that said elastic elements are such that they ensure that the radial forces originating on the different cables 1 'are exactly the same in order to ensure a proper distribution of forces.
- the radial forces being equal, it follows that the tensile forces transmitted by each of the cables will be equal, provided that the surface finish characteristics of the pulley throats are equivalent, and with that the respective coefficients of friction.
