Pit chairlift

The innovation concerns a pit chairlift with at least a motor-driven traction device to which the chair is assigned are, with rollers arranged in holders for guiding the traction device debris, the rollers assigned to the debris are arranged in separate roll holders.

Such a pit chairlift is by "mallets and irons" 1965, No. 1, pp. 17 to 20, previously known. This pit chairlift has the disadvantage that, especially in the case of zigzag running rope debris, which are used to drive the individual chairs, the risk of the rope jumping out of the to guide the rope trunks serving roles. This danger is also when driving through hollows, saddles and Curves given. While trying to adjust the rope guides in the previously known pit chairlifts so that the rope fragments If possible, do not come out of the roller guides. However, this means laborious and labor-intensive adjustment work is necessary, either constantly or at certain time intervals have to be repeated, as the work in the rock also shifts the pit lining, e.g. deforms it is, whereby the associated bracing for the arrangement of the roll holder also their position in change the route. Since these mountain movements are not always noticed immediately, it can happen that between two Adjustment work by shifting the mountains the arrangement the pulley changes and the rope jumps out of the pulleys,

which can lead to accidents.

Another disadvantage of the previously known pit chairlifts can be seen in the fact that these require a fixed transverse distance of the back and forth strand of the traction device. This requires at least for the manufacturer the production of reel holders with different transverse distances for guiding the rope sections.

With these pulley holders, which are fixed at a certain transverse distance between the rope sections, there is also the risk of that they are bent in rough underground mining operations by being dropped, especially during assembly and disassembly or at least the individual roller bearings are adjusted so that that a safe guidance of the rope fragments is no longer guaranteed.

Finally, the well-known pit chairlifts are also up a certain type is defined, i.e. there are pit chairlifts, in which the armchairs are firmly attached to the traction mechanism, and there are pit chairlifts in which the armchairs are non-positive be carried away by the rope debris. In the latter version, the armchairs can be removed from the rope by hand and e.g.

DE-OS 24 00 127 is a roller block for guiding the Pull rope of a railroad, in particular an overhead monorail in underground mine operation with for guiding the Last dreams of the pull rope serving roles previously known, which are suspended in a roller support frame that is attached to a with respect to the running rail of the rail track fixed support bracket is attached and is in a through the length the pull rope attachment arms of the railroad vehicles are located at the specified distance on the side of the running rail,

wherein the roller support frame is movable on the support bracket is attached and from the area specified by the length of the pull rope stop arms of the vehicles of the railroad can be moved out. In one construction, the roller support frame is to be attached to the support bracket in a laterally displaceable manner The support bracket is designed as a guide track extending transversely to the longitudinal direction of the running rail, in which a carriage carrying the roller support frame can be displaced.

Starting from a pit chairlift in the generic term of the type required for protection claim 1 is the innovation the object is to achieve a significant improvement in that an accurate alignment of the individual roll holder - even after mountain movements - is not necessary or is no longer necessary to the extent previously required and is the pit chairlift at least essentially accordingly the resulting rope forces adjusts itself with a variable center-to-center distance (transverse distance) of the tension sections, with a conversion with little effort from fixed to non-positive on the rope debris arranged armchairs to accomplish easily should be.

Starting from a pit chairlift "with at least e η em motor-driven traction means to which the chair is assigned are, with rollers arranged in brackets for guiding the traction device chunks, whereby the rolls assigned to the rubble are arranged in separate roll holders, this object is achieved according to the innovation in that the Roll holder adjustable in height and with regard to their storage are also articulated on all sides, the center distance of the roll holder being continuously adjustable.

In the case of a pit chairlift, align according to the innovation the roles provided for the pulling and return strand are bz \ i /. Reel seat always adjusts according to the resulting rope force and therefore adjust automatically according to the respective Circumstances. Therefore, with such a pit chairlift, there is often only one approximate alignment of the rollers bzvi /. the roll holder required while the almost constantly changes in the Roll holder and thus also the roles in the room automatically balance themselves during the operation of such a system. This is particularly advantageous when the rope is zigzag is guided and / or runs through curves, saddles or hollows. Previously known pit chairlifts, on the other hand, had particular difficulties with so-called zigzag ropes, since it was feared that the rope fragments would run out of the roller guides. This is not the case with a modern pit chair lift more possible, as all reel holders in the room adjust automatically according to the resulting rope force.

Due to the individual suspension of the roll holders, there is the possibility of to arrange all roll holders in "space" independently of the other roll holders, e.g. in relation to an imaginary one Longitudinal central axis, beyond which the back and forth strands are arranged is.

In this way the additional advantage is achieved that you no longer - as before - are bound to a fixed center-to-center distance (transverse distance) of the guides for the rope sections. Rather, the reel holders and thus also the pulleys themselves can be located within the generously dimensioned area set up different transverse distances (center distances), because for this purpose, e.g. the roll holders are only arranged to be transversely displaceable on their suspension and in the desired position Need to be locked in position. In this way, the system can adapt to the prevailing operating conditions

to be set up. There is therefore no need to design and ground different types of pit chairlifts.

Another advantage is that, as a result of the Individual suspension of the cable guides bzvi /. of the roles possible is, a pit chairlift from e.g. a facility in which the armchairs are firmly attached to a traction device, to be converted to a pit chairlift, in which the armchairs can be removed from the traction means by hand and can be carried along by the traction means in a non-positive manner. To do this, you need the rollers on the roller holders only to be exchanged. The individual roll holders can also be attached just as easily because of the individual suspension exchange with their roles.

Finally, the possibility is opened up of the individual roll holders and thus the center-to-center spacing of the rolls to adjust to the prevailing operating conditions without affecting the respective adjacent roller holder in any way solved or influenced in any other way.

Another embodiment is characterized by that the roller holders, each hanging on a bearing part, e.g. on a rail, to the direction of movement of the rope fragments are transversely displaceable. This allows the roll holders to be attached to a rail, e.g. non-positively, in particular frictionally, lock.

According to a further feature, the innovation is characterized by that the adjustment of the roll holder to maintain a minimum distance by one on the bearing part and / or an wsn ". at least one of the opposite Roller holder arranged spacer is limited.

Protection claim 4 describes an embodiment in which the storage of each roll holder as a cross or cardan joint
