Abstract

In a shaft conveyor system with several conveying means or cages which are designed as a frame with supporting floors or a skip with or without at least one supporting floor and which partly fill the shaft cross-section and have a perpendicular gap which runs in the running plane of a rope drive which is driven by one or more driving pulleys and is formed by head and tail ropes which consist of one or more individual ropes, a gap of the cage located in the lowest position accommodating at least part of the tail-rope sag and a gap of a cage located in the highest position accommodating part of the rope return, preferably that of the driving pulleys, as well as the abutment from rope attachment to the relevant cage, the arrangement is made in such a way that, with the objective of a comparatively lightweight design of a conveying means or cages and/or a shortening of the shaft head and the sump, the gap and the rope running plane lie between the inner longitudinal walls (24, 25), adjacent to one another of the conveying means (7, 8) which are connected by the abutment (10) for the rope attachment (20) to form a unit to which a counterweight (23) or conveying means are allocated in the rope drive, in which arrangement, in combination with these features and also independently of them, two cages (224, 227; 223, 228) each, horizontally aligned with one another in a cageway (203, 204), have a common rope attachment and are connected by bars to form a unit (232, 233) which is allocated with a further unit to a common driving pulley (209), the bindings (213; 234, 229) of the rope (212, 230) as well as the respective tail-rope sag (231) in the deepest position of the relevant unit (233) being accommodated in a gap (240) enclosed by the rear sides of the cages (223, 228). <IMAGE>

Description

The invention relates to a shaft conveyor system with a plurality of conveying means or trays designed as racks with supporting floors or a vessel, optionally with at least one supporting floor, which partially fill the shaft disk and have a vertical gap which runs in the running plane of a cable drive driven by one or more traction sheaves , which is formed by upper and lower ropes, which consist of one or more individual ropes, with the gap in the lowest position conveyor bowl located at least a part of the lower cable sag and the gap of the conveyor shell standing in the highest position receives a part of the cable deflection, preferably that of the friction disk and the abutment of the cable fastenings on the relevant conveyor.

With such shaft hoisting systems, the overdriving paths are shortened because the deflection of the ropes can be accommodated at least partially in the gap described, thereby achieving a substantial reduction in the overall height above the shaft and of the shaft sump located under the part of the shaft being used. There is also the possibility of shortening the height of the conveying means consisting of conveying vessels or baskets by combining two baskets or vessels to form one of the conveying means by means of bolts. This includes the possibility of a significant increase in the performance of the conveyor system. - The invention offers these possibilities.

A patent application (P 29 44 515.5) belonging to the patent seeker, which is also directed to the shaft conveyor system described at the beginning, is not part of the prior art. In the shaft conveyor system described there, the rope running plane is oriented transversely to the longitudinal direction of the conveying means if the direction in which the conveying means partially fill the shaft disk is identified as the longitudinal direction. The gap is therefore delimited on its narrow side by bars which hold together the conveyor shell halves interrupted by the gap. The loading of these conveyor shell halves with trolleys can either from the end face of the conveyor bowl through the openings located there, or it must be made through openings in the outer longitudinal walls.

For various reasons, in practice, however, there is a requirement to implement a so-called push-through operation when conveying the frame or when conveying with vessels that have at least one support base. For this purpose, the funding must be designed and arranged so that when one or more carriages, e.g. Conveyor trolleys, on a supporting floor from one side of the shaft, the trolleys standing on the supporting floor on the other side of the shaft run through the opposite opening of the conveyor tray. Depending on the design of the escapement device, which is located behind the shaft or on the supporting floor, the directions of movement of the carriages in the filling location and on the hanging bench are the same or are opposite to each other. The special position of the gap prevents the push-through operation in the older proposal.

The prior art also includes a previously known proposal according to which the conveying means consisting of the conveying bowl is inserted into a loop which is formed by an upper rope, the rope ends of the rope loop being arranged on both sides of the conveying run in the uppermost sole stop and / or Traction sheaves are deflected. Such a conveyor system also allows the construction heights above the shaft and below the shaft in the swamp to be shortened. You can enable the push-through operation described on such a conveyor system, by orienting the rope loop transversely to the longitudinal direction of the conveyor bowl. In all cases, however, one has to accept the considerable difficulties that arise when taking up the loads and the lower cable weight in the conveyor frame and when transferring them to the cable loop. Because these loads occur in the conveyor frame as compressive forces and can therefore only be removed with a very heavy construction, which significantly reduces the payload. In addition, the position of the conveying means is unstable due to the introduction of rope force at the lower end, which has an unfavorable effect on the conveying means.

The invention is therefore based on the object in the above-described shaft conveyor system, in which in any case the loads occurring under the articulation of the ropes in the supporting floor or in the vessel can be absorbed and transmitted as tensile forces, so that the funding is comparatively light, to create the prerequisites for the push-through operation explained. The lighter design is particularly effective at large depths because the lower cable weights are not guided through the construction of the conveyor.

According to a first solution to the problem, the invention provides that the gap and the rope running plane lie between the adjacent inner longitudinal walls of the conveyor shells, which are connected by the abutment for the rope fastening to form a unit which is assigned a counterweight in the rope drive.

This solution according to the invention can be found in a manhole Realize the system, each containing a conveyor bowl with the associated counterweight in two adjacent conveying strands, but it is appropriate, that is, with regard to the higher conveying capacity, perform with a single funding from a funding and the relevant counterweight. Given the width of the trolleys, it is then possible, under certain circumstances, to provide each support floor with a plurality of parallel tracks on which the trolleys stand side by side.

Expediently, the shaft disk is divided in both cases so that the counterweight is accommodated in the shaft disk on one end face of the conveyor bowl and the conveyor bowl is housed in a conveyor strand circumscribed by the shaft cylinder with a polygonal cross-section, the guides of the conveyor being arranged on the long sides .

According to a further solution to the stated problem, the invention provides that the gap is delimited by an average partial length of the adjacent inner longitudinal walls of the conveyor shells and the running plane is oriented perpendicular to the longitudinal walls of the conveyor shells, and that at least between the longitudinal wall parts delimiting the gap and the outer longitudinal walls a continuous support floor is formed.

With this solution, a relatively narrow supporting floor is obtained, on which the push-through operation is possible, but in addition, in two halves of the conveying means, there is still space next to the rope gap, which can be used for other purposes. The exploitation can take place in particular by that tracks are laid on the partial surfaces delimited by the gap and the continuous part of the supporting floor, which run parallel to the tracks on the continuous supporting floor. These additional tracks then also serve to set up carriages, for example trolleys, which are each pulled off before other carriages are pushed on.

Preferably and according to a further feature of the invention, the guides are arranged on the emission sides of the funding means in the latter solution.

According to further features of the invention, this also relates to a shaft conveyor system with a plurality of conveying shells designed as baskets or vessels, which are connected to one another via at least one lower rope and at least one upper rope running over a traction sheave, the traction sheave being arranged above the shaft and securing against overdriving of the conveying shells is provided.

The invention is particularly applicable to conveying systems in open shafts, but can also be used in blind shaft conveying. In particular, the invention is suitable for higher production capacities in shafts with large depths, as have recently been planned in underground mining and currently in hard coal mining. are around 1300 m. In this sense, there are shafts with depths that can no longer be equipped with continuous conveyors, for example with the belt straps that can be used in tonne-long shafts, or with which such conveyors have considerable problems, inter alia due to the dead weight of the conveying body or the technical outlay would kick.

Shaft hoists of the training mentioned at the outset are known. Depending on the division of the manhole panes, they have e.g. four side-by-side dreams, each for a conveyor bowl, to which a traction sheave and thus also a conveyor machine are associated with another conveyor bowl arranged thereon. In the case of open shafts, the traction sheave and carrier are set up on a tower so that the traction sheave can be arranged above the run. This division results in narrow distances between the rope centers in the runs and the need to increase the length of the conveying trays for larger conveying capacities. Lengths of approx. 21.5 m have become known from vessel conveying, which in any case bring about a corresponding fall height of the conveyed material during the filling process.

In order to compensate for the cable center distances at a given wrap angle of the traction sheave, rope steering pulleys are provided in most cases under such traction sheaves. The overdrive protection then generally consists of an end section of the basket guide forming an overdrive path, to which a track slat thickening and / or one or more bounce supports adjoin. This leads to the need for a "free bell" provided over the uppermost stops of the conveying trays in an extended shaft head, in which a catch device for the conveying trays and optionally devices for monitoring the upper ropes are also usually provided.

In the shaft conveyor systems assumed to be known, the necessary weight compensation of the upper ropes by the lower ropes results in a correspondingly long lower rope slack which must be accommodated in a shaft sump arranged under the bottom stop of the conveyor trays. The length of this shaft section increases with increasing length of the conveying trays, because the part of the conveying vessel or basket which protrudes downward beyond the lowest stop into the shaft is also accommodated in it.

The invention has for its object to provide a shaft conveyor system of the type described and given or increased performance so that there is a shortening of the shaft head and the sump with the same or a disproportionate length of the conveyor shells.

According to the invention, this object is achieved in that two conveying trays horizontally aligned with one another in a conveying strand have a common cable fastening and are connected with bolts to form a unit which is associated with a further unit of a common traction sheave, the covers of the cables and the each lower cable sag in the lowest position of the unit in question is accommodated in a gap enclosed by the rear sides of the conveyor shells, which is open on its sides facing the traction sheave and the lower cable bay.

By connecting several conveyor bowls into one unit, the horizonta is enlarged len length of the dreams of the units without increasing their size compared to the conveying bowls combined in the unit. The increase in horizontal length that occurs can be compensated for by a widening, which also increases the cable center distances, so that one usually does not deflect the upper cable below the traction sheave by one or more cable pulleys. Then there is the possibility of arranging strips above the top rope bindings that create a rope slide between the traction sheave lining and the rope on the traction sheave.

By leaving the gap at least one side open as described between the conveyor shells in the units thus created, the units can be moved as far as the traction sheave as planned and in any case accommodate a considerable length of the cable sag between the conveyor shells, thus shortening the shaft sump accordingly. This shortening of the tower and shaft sections described saves considerable investment costs at large depths and high conveying capacities, protects the material to be conveyed due to the reduced headroom and has other advantages. By folding the top ropes together, magnetic-inductive rope monitoring with an appropriate sensor is made possible, which results in a higher degree of rationalization of the conveyor operation.

If the invention is used to combine two shaft conveying systems of a shaft in this shaft, then the times that are necessary for shortening the rope and examining the rope ends as a whole are reduced accordingly speaking.

According to the embodiment of FIGS. 1 and 2, the hanging bench is on the sole designated 1. On the base 1 a shaft structure 2 is erected, the supports of which are designated 3 and 3 '. The shaft denoted by 4 in FIG. 1 is shown in cross section in the top view of FIG. 2. The shaft disk is divided in such a way that a polygonal conveyor run 5 and a counterweight run 6 result. In the funding run runs a unit that is created by the merger of two funds 7 and 8 and is designated 9. The connection takes place essentially via bolts and a cross member 10 (FIG. 1), which is used for articulating the conveyor cables forming the cable drive, generally designated 11. This includes the upper cable 12, which is deflected via two adjacent cable pulley guides 13 and 14 as shown in FIG. 1 to the right in the upper part of the conveyor frame 2, so that it can run over a traction sheave 15, which has a gear 16 and a motor 17 sits on a shaft. According to the darge illustrated embodiment, the upper rope consists of two individual ropes 18, 19, for which adjacent rope grooves are provided on the traction sheave 15. The upper rope 12 is attached to the cross member 10 with a special thimble 20. Its other end is articulated to a counterweight 23 via a thimble 21 at 22.

There is a gap between the two funding halves 7 and 8, which runs in the rope running plane and is delimited by the inner longitudinal walls 24, 25 of the two funding halves.

As can be seen in particular in FIG. 1, this gap enables an upper position 26 ′, represented by dashed lines, of the unit 9 consisting of the conveyor halves 7 and 8, in which the cable deflection 13 consisting of the rollers is located on the lower part thereof in the gap. This also applies to a part of the lower cable sag, which, however, is not shown in the illustration of FIGS. 1 and 2 when the unit is in its lower position.

A safe braking of the unit in the event that an overdriving occurs is achieved on the one hand by the fact that several safety cushions 29, 29 'arranged one above the other are fastened in the conveyor frame 2 below the impact carriers shown at 26-28. On the other hand, at a corresponding distance above the thimble 20, there is a bar 20 'on each of the two ropes 18 and 19, which causes a rope slide on the traction sheave in the traction sheave lining when exaggerated. Instead of a bar, too a slide chain can be provided.

Since the articulation of the two upper ropes, which is shown in the top view of FIG. 2 at 30 and 31, is below the center of gravity of the unit 9, the position of the unit is essentially stable even at higher conveying speeds, so that the loading of the shaft guides is be kept within the permissible range. These requirements are met in all embodiments of the invention.

1 and 2 lie on the outer longitudinal sides 34, 35 of the unit 9 and the two conveyor halves 7 and 8 forming them. There are the usual guide shoes 36, 37 for the track slats 38, 39 laid vertically in the shaft attached. The guide of the counterweight 23, which is rectangular in cross section, lies on its narrow sides 40, 41 and in turn consists of corresponding track slats and guide shoes.

As indicated by the arrows with B and E in the funding halves 7 and 8, a so-called push-through operation is possible on the hanging bench and in the filling location. Here, trolleys or material-transporting trolleys are pushed on in the direction of arrow B and push the trolleys already standing on the conveyor halves 7 and 8 in the direction of arrows E, which run in this direction.

When the unit 9 is designed as a frame conveyor, it is provided with a plurality of trays, which is known per se and therefore only in the simplified representation of FIGS. 1 and 2 is reproduced with two trays.

The exemplary embodiment according to FIGS. 3 and 4 differs from the exemplary embodiment according to FIGS. 1 and 2 only by the deflection of the upper cable 12 on a deflection pulley 43 or 44, which produce the predetermined wrap angle of the upper cable 12 on the traction sheave 15. In this case too, the rope slide is brought about with the aid of the strips 32 in the traction sheave linings and the ropes 18 and 19 when exaggerating.

In the exemplary embodiment according to FIG. 5, an unloading station of a double-shaft shaft conveyor system with combined conveying means 50, 51 is realized. There is therefore no counterweight. The conveyor shells 50 and 51 each have on their end faces 52, 53 a track slat guide 54, 55 of the type which has been described above in connection with the exemplary embodiment according to FIGS. 1 and 2. The inner longitudinal walls 56 and 57 of the two conveyor shells 50 and 51 are adjacent to one another and delimit the gap designated 60 with short sections 58, 59. This gap is again in the rope running level, however, in contrast to the embodiment according to FIGS. 1 and 2 or 3 and 4, the trays are oriented transversely to the rope running level. The gap in each conveyor 50 and 51 is limited by the transverse walls 61, 62. These transverse walls run parallel to the outer transverse walls 65, 66 of the conveyor.

As can be seen in FIG. 4, the distance between the partial longitudinal walls 58, 59 from the outer longitudinal walls 67, 68 of each conveyor 50, 51 results in one or more continuous ones _T ragböden 69, 70 on each conveyor. If the trays are arranged on the conveyor head, the divided spaces 71, 72, which are delimited on the inside by the inner transverse walls 61 and 62 and on the outside by the outer transverse walls 65 and 66, can be used as further trays. These support floor halves can be loaded in the direction of the cross arrows 74, 75, while the continuous support floors 69, 70 can be loaded in the direction of the arrows 76, 77 in the push-through mode.

Fig. 6 shows that the outer part of the slot between the conveyor halves can be used for the transport of long material, material and for cable travel. In Fig. 6 a total of five trays are mounted in the slot, which are designated 69a-69e. The trays can be pivoted upward about horizontal axes in the direction of the arrows, so that long material can be accommodated in the conveyor slot.

The embodiment also shows the arrangement of the traction sheave 80 for the upper rope system 81, which in turn consists of one or more ropes, on a support 82 bridging the shaft, so that part of the rope deflection on the traction sheave 80 can be accommodated in the gap 60 in the uppermost position of the double conveyor . As a safety device, a cushion 83 is in turn mounted in the shaft conveyor frame above the traction sheave 80.

For the embodiments according to the invention according to FIGS. 1 and 2 or 3 and 4, an embodiment is shown in FIGS. 7a and b, which as a vessel with two one above the other lying support floor levels 85, 86 is formed. The two supporting floor levels 85 and 86 are realized in each of the two conveying means 7 and 8 joined together to form a unit by the cross member 10. As shown by the arrows 87 and 88 in FIG. 7b, the trays can be folded upwards and in this position enable the conveying vessels 89, 90 to be loaded from above in the direction of the arrows 91, 92. The lateral openings in the connection carrier height However, 10 must then be closed. The vessels are emptied from the side. The flap locks 91 are automatically opened via a control cam and a control rod 92 in the uppermost position of the unit.

8 and 9 in a practical embodiment of the invention, the thimble 93 is designed in such a way that it is as narrow as possible perpendicular to its side plates 94, 95 on the one hand with a view to reducing the cable gap width and on the other hand avoids the plane of the side plates protruding parts. The clamp thimble can therefore advantageously also be applied to shaft conveyor systems other than those designed according to the invention.

Essentially, a common main thimble heart 98 is provided for all of the six ropes 104-109 of the upper rope system according to the exemplary embodiment, so that there are two congruent side shields 94, 95 of relatively great thickness which rest on the outer surfaces of the thimble heart 98. The relatively large thickness of the side shields in turn allows them, inter alia, to brace the side shields with the head thimble screws 99 on one side and screws 100 on the opposite side in the side shields so that there are no protruding parts on the outside of the side shields. This also applies to other organs of the thimble, for example a tensioning device of the main thimble heart 98, not shown, the joint bolt 114 of a universal joint, which can be attached to the thimble and is explained in more detail below, and the screws 102, 103 of a clamping device 103 ', which is used to attach the cable slide 32 which is assigned to each conveyor cable.

The six round ropes 104-109 are routed behind the main thimble heart 98 around a secondary thimble heart 98 '. They are assigned to individual terminals 104a-190a in the thimble heart, which allow different lengths of the individual cables to be compensated for. A common terminal block 110 is assigned to all the ropes 104-109.

The secondary thimble heart 98 'sits on an axis 120, which in turn does not project outward beyond the outer surfaces of the side shields. It is used to fasten a bracket 121 which is movable in the direction of the double arrow according to FIG. 8 between two extreme positions, one of which is shown in dashed lines. In the other position shown in solid lines, the ropes are fixed and the secondary thimble heart 98 'assumes the dot-dash position shown in FIG. 8.

If the ropes are to be re-tensioned, the first is Terminal block 110 removed. With the help of a crane or a block and tackle, which is attached to the bracket 121, the bracket is tightened and thereby pivoted clockwise. Then he takes the end position shown in dashed lines. This creates a slack rope, which makes it possible to loosen the thimble heart 98. This happens, among other things, with devices known per se, which are therefore not shown.

Then, if necessary, all ropes, but also only individual ropes can be retensioned, for which purpose the pulley is attached to each of the ropes that are to be tightened. After the ropes have been tightened, the main thimble heart 98 is tightened again by pivoting the secondary thimble heart 98 counterclockwise over the bracket 121 and thereby returning it to the position shown in solid lines in FIG. 8.

The two side shields each have an extension 111 or 112 beyond the thimble heart 98. The two extensions 111 and 112 serve as a bushing for a joint, the joint axis 113 of which is realized with a bolt 114. The joint serves to support a joint body 115 with a joint axis which is 116 and which runs perpendicular to the geometric axis 113 of the joint bolt 114. The geometric axis 116 is assigned to a hinge pin 117. The overall arrangement forms a universal joint, which is connected via the hinge pin 117 to a socket, which in turn is attached to the cross member 110. 10-12, the shaft disk 200 is circular and is therefore provided with a ring structure 202. It has two conveyor strings 203 and 204, respectively. Above the shaft, in the direction of one of the main axes of the disk, there is a stage support 205 on which the double-mounted traction sheave shaft 206 is mounted. Between the two bearings 207 and 208 there is a traction sheave 209 with a plurality of cable grooves 210 for an upper cable 212 consisting of several individual cables. The upper cables are attached with a cover 213 and a cable fastening 214 on the upper side 215 of an intermediate floor 216. The traction sheave shaft 206 is coupled at 211 to the drive shaft 217 of a transmission 218, the drive shaft 219 of which is driven by a motor 220.

In each run there is a guide 221, 222 for a conveyor bowl 223, 224; Corresponding guides 225, 226 for conveyor trays 227, 228 are provided on the opposite shaft joints. The conveyor trays Kings _- nen be formed as skips or cages.

As can be seen in particular from the illustration in FIG. 10, two conveyor trays 224, 227 and 223, 228 are horizontally aligned with one another in a conveyor run 203, 204. They have a common cable attachment to the intermediate floor 216 described, which is provided for the conveying trays 224, 227; In contrast, the conveying trays 223 and 228 which are combined with one another are assigned an intermediate floor 237 which corresponds to the floor 216. Accordingly, both the bottom 216 and the bottom 237 have fastenings for the cover 228 and 229 of a lower rope 230 on their respective underside 238. The sub rope 230 has a slack 231, which is always present and serves to balance the weight of the top ropes.

The two conveyor bowls 224, 227 and 223, 228, which are aligned with one another in a conveyor strand, in turn form units which are designated by 232 and 233. Bars 235, 236 (FIG. 11) are used for the connection. The two units 232, 233 are driven together by the traction sheave 209. The bars are otherwise attached so that gaps 239, 240 arise between the conveyor shells 224, 227 and 223, 228. In these columns, as can be seen from FIGS. 11 and 12, the bindings 213 and 234 and 229 of the upper and lower ropes including their rope fastenings and the respective lower rope sag 231 are accommodated in the lowest position of the unit in question. Plastic strips 242 are attached above the covers of the upper rope, which, according to the illustration in FIG. 12, get between the traction sheave lining and the relevant ropes when exaggerated and produce a rope slide on the traction sheave there. This leads to the fact that further exaggeration of the units 232 and 233 is prevented.

Otherwise, the carrier 205 has pawls 245, which reach under the intermediate floors 237 and prevent the units 232, 233 from falling when the cable slide occurs.

A safety cushion 246 is arranged above the rope pulley 209 and serves as a buffer for the two units 232, 233. A safety cushion 247 corresponds to it in the lower area of the shaft.

Inductive rope monitoring is not shown, which detects the rope monitoring in cooperation with an appropriate sensor. However, it can be seen from the illustrations that rope deflection disks are not present. The conveyor trays 224, 227 and 223, 228, which form the units, can be loaded simultaneously at the various stops, so that the loading and unloading times are reduced correspondingly compared to conventional systems, which leads to an increase in the daily conveying capacity.
