Description

Conveying and transport system for tunnel structures

The invention relates to a conveying and transport system for tunnel structures according to the features in the preamble of claim 1.

Tunnel structures are generally referred to as mountain passages with a developed tunnel tube, which are laid out for traffic routes such as railways, roads or shipping tunnels and manufactured using mining methods. Tunneling is one of the most demanding and difficult tasks in the construction sector. A large number of tunnel construction equipment is used to construct the tunnel structures. These include tunnel boring machines for demolition of the rock, devices for loading and discharging the rock, as well as equipment for concreting or removal of the tunnel tube as well as equipment for supply and transport. An essential component in the manufacture of a tunnel construction is therefore the conveying and transport system. A method for producing a tunnel is described in DE 102 42 574 A1. The overburden and / or material required in the tunnel is conveyed by means of a monorail.

A frequently used in tunneling means of transport are monorails. A monorail conveyor is a device for transporting material in containers or bundles. These are guided by trolleys on a suspended rail track and usually pulled by self-propelled. Also possible is a drive through Häspel with ropes. Even people can be transported in special transport cabins with monorails.

The advantage of monorail conveyors or generally of first-bound conveyor and transport systems is their insensitivity to sole lifting, since on the sole of a route no planum must be made, but the rails are suspended from the roof. Also, the first-bound conveying and transport systems are characterized by their high flexibility, which makes it possible to extend or shorten the rail travel within a short time.

In addition to the monorail monorail systems widely used in mining, double-decker monorail systems are also known. A two-rail monorail, referred to therein as a double-rail track, belongs to the state of the art through EP 1 085 128 B1. Such monorails have two parallel juxtaposed rail tracks of rails, which are suspended via a support structure to the roof of the tunnel. On the rail tracks are guided by carriages on drives.

The conveying and transport system contributes significantly to the efficiency of tunneling. This applies in particular to tunnel structures that are provided with segmental lining. As tubbing components of the outer shell of the tunnel are called. This is a prefabricated concrete segment. Several such concrete segments then form a complete ring. The tunnel or the tunnel tube is composed in the longitudinal direction of a plurality of rings. Correspondingly many segments are required as the length of a tunnel structure progresses. A single tubbing often weighs more than 10 tons. The conveyor and transport system must be correspondingly efficient. The requirements for the conveyor and transport system for the manufacture of tunnel structures are therefore becoming increasingly complex.

The invention is based on the prior art based on the object to improve a conveyor and transport system for tunnel structures plant or system technology and to increase the performance.

The solution to this problem consists in a conveying and transport system for tunnel structures according to the features of claim 1.

Advantageous embodiment and further developments of the conveying and transport system according to the invention are the subject of the dependent claims 2 to 10.

The conveyor and transport system according to the invention has a firstgebunden roadway with two parallel juxtaposed rail tracks of rails. The rails are hung on a support structure on the roof. On the rail tracks are guided by carriages on drives. Usually, a composite of carriage is used.

According to the invention, at least one support carriage on a hoist. In practice, have a number of support carriages, ie several carriage, especially the majority of the carriage, own hoist. It is furthermore essential to the invention that at least one carrier carriage, in particular a plurality of carrier carriages, has a gripping device, in particular a tubbing gripper. With gripping devices in The shape of tubbing grippers is a recording and lowering of tubbing. Such gripping devices are designed like tongs.

The special construction of the tubbing gripper enables the secure transport of tubbing stacks at high speed of the carriages.

In an advantageous embodiment of the conveying and transport system according to the invention, the support structure on transverse sleepers arranged longitudinal beams and suspension means, wherein the rails are fixed on the longitudinal beams. This configuration makes it possible to increase the buoyancy and thus the performance of the two-rail monorail of the conveyor and transport system.

One aspect provides that the longitudinal beams are formed by box sections.

Each suspension means has a staple which can be fixed to a transverse sleeper and a suspension means, in particular a chain or a rope.

Another essential aspect of the invention, which contributes to both the system and system improvement of the conveyor and transport system as well as to increase the performance, is that the support carriages are each self-propelled.

A particularly advantageous embodiment of the conveying and transport system according to the invention provides that an escape route is integrated into the roadway. This escape route allows two trains to pass each other. So a shuttle or a shuttle transport is possible.

Entrance and exit side of the escape route is provided a turnout system. In the context of the invention, it is provided that the points system has a rail unit arranged in a swivel frame, wherein the swivel frame is pivotally connected at one end to a rotary unit and at the other end to a swivel traverse supported. The turntable comprises a turntable and / or a turntable. Turntable and / or turntable are equipped with rail sections, especially curved rails. By turning or pivoting of turntable and / or turntable, the connection between the rail tracks of the road and the escape route or the rail unit can be made in the swing frame. The turntable or the turntable and the pivot arm can be operated simultaneously or sequentially. The drive is either electric or hydraulic by means of hydraulic cylinder, winch or sprocket.

A further advantageous aspect provides that the rail tracks in the area of the avoidance path are lowered in relation to the rail tracks in a main section in the height level. As a result, the tunnel cross-section can be used to pass the tracks. In the lowered height level, a larger tunnel width is available, in particular for round tunnel cross sections.

A further measure which advantageously improves the conveying and transport system provides that a continuous conveyor, in particular a belt conveyor, is arranged above the transverse sleepers. In particular, the rock resulting from tunneling can be transported away via the belt conveyor. An advantage is that the wheels of the carriage, which roll on the rails, are arranged next to the continuous conveyor. This also makes it possible to make the best possible use of the available height.

Overall, the invention provides a plant and system technology improved conveyor and transport system for tunnel structures with high performance. The conveyor and transport system uses the upper half of the tunnel cross-section as working plane. As a result, the spatial relationships of the tunnel cross-section can be exploited optimized. Tunneling can work in parallel and effectively on both levels, ie the upper working level and the lower working level. This is a Parallelization of otherwise time-delayed operations possible. In particular, the conveying and transport system is characterized by its high carrying capacity. Due to the compact, load-bearing design of the supporting structure and the design of a two-rail monorail system according to the invention, the driving or conveying / transporting speed can also be increased considerably. This also contributes to increasing the performance of the conveyor and transport system.

With reference to the figures 1 to 19, an inventive conveying and transport system is explained in total. The drawings are partially schematized and / or technically simplified.

The conveyor and transport system has a suspended on the ridge F of a tunnel structure, so first-bound lane 1. The roadway 1 comprises two parallel arranged rail tracks 2, 3 of rails 4. The rails 4 are suspended on a support structure 5 (see also Figures 7 to 10).

The structure of the transport system is based on that of a two-rail monorail. At the rail tracks 2, 3 are 6 drives 7 run over drives. Several carriage 7 form a train 8, as shown in Figure 2. There a total of seven trolleys 7 are shown. The three support carriages 7a shown on the left in the image plane form the rear part of the train 8 and are equipped with tubbing segments 9. This carriage 7a are also referred to as heavy-duty hoist. Furthermore, a support carriage 7b is equipped with units 10 for energy supply and distribution. A carriage 7c is equipped with a crew cab 1 1. The right in the image plane front support carriage 7d carries a cab 12th

FIG. 1 shows the installation situation of the conveying and transport system in the tunnel cross section. It can be seen that the conveying and transport system is arranged in the upper half of the tunnel cross-section. With 13 a ventilation channel is designated. This is arranged next to the supporting structure 5 of the conveying and transport system. The sole S is concreted and forms the substructure for a later to be laid track.

Reference to the figures 7 to 10, the support structure 5 is described in detail. The support structure 5 has arranged on transverse sleepers 14 longitudinal beams 15. The longitudinal beams 15 are formed by box sections. The box profiles have a rectangular cross section with a length a and a width b, wherein the length a is greater than the width b. The sleepers 14 are fixed or suspended by suspension means 16 on the ridge F of the tunnel structure. A suspension means 16 in each case comprises a clamp 17 fixable on a transverse sleeper 14 and at least one suspension element 18 in the form of a chain. The support means 18 are determined on the first side on tubbing construction, preferably by means of anchor technology. For this purpose, in particular adhesive anchors can be used. On the longitudinal beams 15, the rails 4 of the lane 1 are laid. In principle, each support carriage 7 can be self-propelled. Of course, it is possible that 8 non-powered carriage or hoists are integrated in the train.

Figures 3 to 6 show a support carriage 7 or 7a, a so-called heavy-duty Hubfahrwerk. The drive 6 comprises a total of eight wheels 19. In each case two wheels 19 are mounted on a longitudinal rocker 20. The drive of two wheels via an electric motor 21st The longitudinal rocker 20 also consists of a box section. In the interior of the box sections, a swinging distributor transmission, not shown here, is arranged, via which the torque distribution to the wheels 19 takes place. The longitudinal rocker 20 itself is suspended on a vertical strut 22 at a pivot point 23 swinging. On the vertical struts 22, a support frame 24 of longitudinal profiles 25 and transverse profiles 26 is attached. The support frame 24 carries a winch 27. This is driven by at least one - in the embodiment shown here - by two electric motors 28. On the support frame 24, a hoist 29 via pulleys 30 and the total of four cables 31 of the winch 27 can be raised and lowered suspended. The lifting mechanism 29 comprises vertical supports 32 and longitudinal members 33 and bottom-side supporting beams 34 with an integrated gripping device 35. The gripping device 35 comprises displaceable gripper arms 36 for receiving and fixing the segments of segments 9 within the supporting beams 34.

Above the sleepers 14, a continuous conveyor 37 in the form of a belt conveyor on the support structure 5 is arranged. 1, the continuous conveyor 37 rests on the sleepers 14 of the support structure 5 between the suspension means 16. The height level of the continuous conveyor 37 is substantially at the height level of the wheels 19 of the carrier carriages 7 rolling on the rails 4.

In the lane 1 is an alternative route AS integrated with two parallel side by side guided road sections 1A and 1 B. About the avoidance route AS can two train assemblies 8 and two Traglaufwagen 7th Pass each other and pass each other. FIG. 13 shows the situation in the avoidance route AS in which two train assemblies 8 pass each other.

As shown particularly in FIGS. 11 and 12, a turnout system 38 is provided on the entry side of the escape route AS. The same applies to the situation on the exit side. The supporting structures 5 of the rail tracks 2, 3 in the area of the escape route AS are lowered in relation to the rail tracks 2, 3 of the carriageway 1 in the main line section in the height level. This can be seen in particular in Figures 12 and 13. In this way, the width in the central region of the tunnel cross-section for the escape route AS with two parallel juxtaposed rail tracks 2, 3 are exploited.

The points system 38 includes a pivot frame 39. The pivot frame 39 can be seen in particular in Figures 14 and 15 and 18 and 19. In the swing frame 39, a rail unit 40 is arranged, which can be pivoted together with the swing frame 39. By pivoting each of the connection to the rail tracks 2, 3 of the roadway 1A and the roadway 1 B can be made in the escape route AS.

The swing frame 39 is hinged at one end 41 to a rotary unit 42 pivotally. At its other end 43, the swing frame 39 is supported on a pivoting traverse 44.

The rotary unit 42 is connected to the entry or exit side connecting section 45 of the supporting structure 5 of the roadway 1.

The rotary unit 42 has a support frame 46. About the support frame 46, the rotary unit 42 is suspended from the ridge F in the tubbing 9. In the support frame 46, a central rotary tube 47 is arranged. The rotary tube 47 has an upper at its upper frame side end Support plate unit 48 on. About the upper support plate unit 48, the rotary tube 47 is fixed to struts 49 of the support frame 46.

At our end of the rotary tube 47, a lower support plate unit 50 is connected to the rotary tube 47. On the lower support plate unit 50, a turntable 52 for the swing frame 39 and a turntable 53 is rotatably or pivotally mounted by incorporating a slide bearing 51. On the turntable 53 cam rails 54 are arranged.

The swing frame 39 has upper longitudinal members 55, which are connected to each other via cross braces 56. From the longitudinal beam 55 go vertical struts 57, which carry the rail unit 40.

The upper connection of the swing frame 39 to the rotary unit 42 is made via an upper pivot frame connection 58. The swivel frame connection 58 has a bearing plate 59, which is rotatably or pivotably mounted with the inclusion of an upper slide bearing 60 relative to the rotary tube 47.

Above the bearing plate 59, a drive ring 61 is arranged and fixedly connected to the bearing plate 59. By operating the drive unit 62, the drive ring 61 and with this the swing frame 39 can be pivoted so as to make depending on the passage direction of the train 8 the connection to the lane 1A or the lane 1 B in the escape route AS. When pivoting the turntable 53 and the turntable 52 are locked together by a lock, not shown here.

Figure 14 as well as Figure 18 show the swing frame 39 in a pivotal position to the right, whereas Figure 15 and Figure 19 show the swing frame 39 in a pivotal position to the left.

In the area of the avoidance path AS, the continuous conveyor 37 is guided on a portal 63 (see FIG. 13). The portal 63 is supported on both sides of the respective support structure 5 of the roadway section 1A and the carriageway section 1 B from.
