Definitions

the invention relates to a control device for the pivoting movement of a guide rail of an elevator formed from a plurality of guide rails, on the guide rails of which a load-lifting means which is pulled by a hydraulic drive can be moved and at least one guide rail can be pivoted relative to an adjacent guide rail by means of a pivoting device.
Such elevators are generally used in the construction and auxiliary construction industries for the transport of loads to and from the roof, which are generally telescopic inclined elevators, ie elevators on whose telescopic guide rails a load suspension device can be moved. It has become known that to design the upper or second uppermost rail so that it can lay on the roof and adapt to the roof pitch.
the upper guide rail cannot be telescoped relative to the one below it, but can be swiveled so far that it can be swiveled down to a position parallel to the underlying guide rail and can be fixed here in a stowed position.
This is particularly advantageous because the road traffic regulations in various European countries only allow a maximum length of the elevator when transporting it with the telescopic rails retracted; since the telescoping requires a certain overlap, the length of the elevator in the transport position inevitably increases with an increasing number of telescopic rails.
the last guide rail was designed to be angled by more than 180 ° against the penultimate guide rail.
the object of the invention is to remedy this, i.e. to find a control system in which rope breakdowns are prevented in both directions of movement of the pivotable guide rail by keeping the so-called sled rope (load rope) sufficiently tensioned.
the known elevators have several control slides combined in a control block, one of which is assigned to the load winch drive, a second to the telescopic rail drive and a third to the drive of the inclination adjusting cylinder. It is therefore an additional object of the invention to integrate the control for keeping the load rope taut during the swiveling movement of the swiveling rail into the known control using largely existing hydraulic elements.
a control slide designed as a 4/3-way valve which controls the liquid flow coming from the pump when the swiveling guide rail is erected from the stowed position into the use position (for example: system on the roof ) feeds a control line, which opens a releasable check valve located in the closed circuit of the load winch motor, so that the motor, as it were on the output side, can suck the liquid through a bypass into a closed circuit.
the winch assigned to the load winch motor releases rope.
In the bypass line is a bias valve opening towards the output side of the engine is switched on, its Vor tension is such that the rope is always kept taut.
the hydraulic fluid coming from the pump is supplied to the input side of the motor via a pressure reducing valve, so that it catches up with a low torque via the associated cable winch.
This swivel device can in principle be of any design; it can be accomplished, for example, by an electrically driven servomotor. Preferably, however, a hydraulic cylinder is used for this, as is characterized in the subclaims.
Fig. 1 denotes an inclined elevator, which essentially consists of a chassis 2 on which the telescopic guide rails 3, 4 and 5 are supported.
a wheel support 13 is arranged at the upper end of the telescopic guide rail 5.
a further pivotable guide rail 6 is articulated, which can be moved from the stowed position 20 via the position (shown for example at 6) into a use position (contact position 21), so that after telescoping the telescopic guide rails 3, 4 and 5 in the direction of arrow 22 the roof of a building 12 can be created.
the item number 7 denotes a load suspension device (slide) on which a load rope 8 engages.
the load rope is a roller 9 at the upper end of the schwenkba Ren guide rail 6, further via a roller 10 approximately in the bend area and finally guided to the load winch drive 11. From Fig. 1 it can be seen that during the pivoting movement in the direction of arrow 19, the load rope 8 must be extended (ie, the load winch drive 11 must deliver rope), while contrary to the arrow direction 19, the load rope 8 must be shortened (ie, the load winch drive 11 must Get rope.
the building (not shown) is located in the image plane on the right, so that the wheel support 13 can be supported on it.
the hydraulic cylinder 14 is actuated in the sense of "retracting the piston rod"
the pivotable guide rail 6 will pivot in the left-hand sense in the image plane until it abuts approximately the telescopic guide rail 5. It arrives in the stowed position 20 shown in FIG. 1.
the control according to the application can be seen in FIG. 3. It can be seen that four 4/3-way valves are combined in a control block 40, of which the 4/3-way valve 41 is used to control the load winch drive (the associated load winch has been designated 44 and the associated brake release cylinder 45), the 4th / 3-way valve 42 is assigned to the telescopic rail drive and the associated 4/3-way valve 43 to the action of the hydraulic cylinder 46 for the inclination adjustment.
the additional control slide 27 serves to control the hydraulic cylinder 14 and the slack rope protection of the load winch motor 32 of the load winch drive 11.
the pressure fluid supplied by the hydraulic pump 25 via the pump line 26 arrives in the switching position a of the control slide 27 in the section of the pump line 26 behind it, so that the piston chamber 35 of the hydraulic cylinder 14 and the control line 28 are acted upon at the same time.
the unlockable check valve 50 is opened via the control line 47, so that the pressure fluid can flow out of the annular space 36 via the line 37.
the hydraulically unlockable check valve 29 is opened via the control line 28.
the load winch motor 32 can suck hydraulic fluid from the bypass line 31 while overcoming the preload of the preload valve 30 and press the liquid into a closed circuit via the lowering brake valve 49, which allows free flow, in the sense of “releasing rope”.
the pretensioning of the pretensioning valve 30 ensures that the rope is held taut. With the erection movement described above (swiveling the pivotable guide rail 20 in the direction of arrow 19) the slack rope protection is thus ensured.
the assignment of the pressure reducing valve 33 ensures that the full pressure is present in front of the pressure reducing valve 33 under the piston ring surface 36, which is necessary for raising the pivotable guide rail (e.g. from the roof to the vertical position).
