DE2365598A1 - Air shaft maintenance lift cage - has emergency cage with separate winch using its rope as guide - Google Patents

Abstract

The cage is particularly for use in maintenance work in mine shafts, being raised and lowered by a winch on a platform to the side of the shaft, and from which the rope is reeved to the cage via guide pulleys. One or more of the winch ropes acts as a guide for an emergency cage, whose rope is reeved via pulleys on a frame or a travelling crab to an emergency winch. Where working platforms unfold from the main cage, the emergency one can be used to ferry materials and/or personnel to and from it while it is locked in a particular position.

"Device for driving into an air shaft or the like"

Eliminated from P 23 64 280 * 0-22

The invention relates to a device for driving through an air shaft or the like, - with access cage, cable arrangement and winch, with the winch on a platform at the side above of the air shaft mouth is set up and the driving cable arrangement guided over pulleys and connected to the access cage Has driving ropes. - The term air shaft also includes similar

borrowed shafts that are used in underground operations or underground structures, are common; in the following there is always only one air shaft spoken.

In a device of the type mentioned known from practice, by means of which for the purpose of inspection or for implementation various repair work from the access cage Air shaft walls to be inspected or operated are special Measures for emergencies with blocked access cage are not intended.

The invention is based on the object of further developing a device of the type mentioned at the beginning using simple means in such a way that that the air shaft is easily accessible when the transport cage is blocked above the same.

The invention consists in that at least one of the driving ropes is used as a guide rope for an emergency cage and that the emergency travel cage with at least one emergency travel rope via others arranged on a frame or on a pulley carriage Pulleys are connected to an emergency winch.

The advantages achieved by the invention can be seen in the fact that in a structurally very simple and reliable manner Driving into the air shaft above the blocked access cage is made possible. If the access cage has, as preferred, one In particular, the fold-out work platform, the emergency cage can be used for material, but also for the transport of people will.

In the following the invention is based on only one embodiment

Leadership example illustrated drawing explained in more detail. It show in a schematic representation

Fig. 1 is a vertical section through an air shaft with the device according to the invention,

2 shows a section in the direction A-B through the object according to FIGS. 1 and

3 shows a section in the direction C-D through the object according to FIG. 1.

The device shown in the figures is used to drive through an air shaft 1. It is equipped with an access cage 2, which is provided with a working platform 3, a driving cable arrangement 4 and a winch 5. The winch 5 is located on a stage 6 laterally above the air shaft mouth 7. The driving cable arrangement 4 has pulleys 8, 9 guided Driving ropes 10. These are connected to the access cage 2. In particular from Fig. 1 it can be seen that above the air shaft mouth 7, a framework 11 with running rails 12 crossing the duct mouth 7 is arranged. The distance between the rails 12 of the air shaft mouth 7 corresponds at least to the height of the access cage 2. On the rails 12, a pulley carriage 13 is guided with the pulleys 8, of which the Guide the driving ropes 10 to the access cage 2. In the embodiment, two driving ropes 10 are provided for the purpose of connection of the access cage 2 are guided in a loop, one end being firmly attached to the pulley carriage 13, while the other is guided to the winch 5 via one of the pulleys 8 already mentioned. The access cage 2 thus hangs on, as it were

Deflection roller carriage 13 and can be moved with this over the cross section of the air shaft 1, which is through a vertical and more or less diametrical partition 14 is divided into two air ducts 15, 16, one for the fresh air supply in the direction of arrow 17, another for the exhaust air discharge in the direction of the arrow 18. So for the purpose of the procedure above the air shaft 1, the access cage 2 must be raised so high, that the movement is not hindered by this partition 14. This has been indicated in FIG. In addition, the access cage 2 must be introduced into the air shaft 1 or into one of the air ducts 15, 16 Deflection vanes 19 for the air deflection initially to the side be driven, including special rails 20 and of course Appropriate actuation devices are also provided ο

The frame 11 has, above the winch stationarily arranged guide rollers 21, so that a particularly clear and simple cable guide is possible "to the move the Umlenkrollenwagen 13 of the winch 5 remote side, is on the framework 11 on the the stationarily arranged guide rollers a mooring winch 22 is arranged on the opposite side. The backward movement into the position shown happens easily because the driving ropes 10 exert a force component on the pulley carriage 13, which moves it back

According to the invention, one of the driving ropes 10 is now provided with an emergency cage 24 equipped, which is attached to the associated driving rope 10

is led. The emergency travel cage 24 is provided with an emergency travel rope 25, which over further deflection rollers 26 on the steering roller carriage 13, for example, “connected to an emergency winch 27 on the frame 11 is.

The operation of the device according to the invention is very simple ,, the recognizable in FIG _o 1 bay doors 28 are mounted, then can be released for the driving cables 10 of the Befahrkorb 2 with its working platform 3 in the corresponding air ducts 15 and 16 by means of the two winches 5 . Once the Befahrkorb is retracted into the air shaft 1 2, the platform 3 can zn a stage platform to be extended 30 and zw & z, the one a segments 29 which initially formed the walls of the Befahrkorbes 2, by means of hand winches or the like are lowered. The platform 3 then has an almost semicircular cross-section, so that the entire. Shaft wall - can be checked by the operating personnel without risk. During this work, the required material can be transported with the hot drive cage 24, the operating personnel can also be brought to and from the work platform 3 ο When the work is finished, the segments 29 of the stage platform 30 are folded up again on the lift cage 2 and < ä®E access cage 2 is sucked up to obea »Then access cage 2 can be placed over the.
