Description

SPECIFICATION Tunnel etc. lining setting machine This invention relates to a lining setting machine for use in gallery driving in underground working or tunnelling operations in conjunction with a section cutting machine, having a lifting and lowering cutting arm, the lining setting machine comprising a transporting and working scaffolding and a lining setting device, in which the transporting and working stage travel on an overhead track and is used for the transporting and manipulation of lining sections, such as mine arches, the lining setting device being used to set the lining section in place with force.

(The above is restricted to gallery driving in underground workings or tunnelling operations using a section cutting machine. However, a section cutting machine can also be replaced by an impact-head machine for example. Accordingly, all the following statements referring to a section cutting machine remain valid when an impact-head machine is used instead of a section cutting machine.) Section cutting machines have been used for a long time for gallery driving in underground workings or tunnelling operations, and there are many known embodiments (see for example articles in "Gluckauf", viol.11 9, no.

4, p. 144 and no. 14, pp. 666-667, both published in 1983). Lining operations following cutting operations at the working face are particularly important, because lining takes three to five times as long as cutting.

In order to facilitate the lining of galleries driven in underground workings and tunnels by means of section cutting machines, and more particularly to complete the operations in a shorter time, lining setting machines of the type initially defined have been developed. However, the design of these lining setting machines has not yet been optimised.

In particular, there is not always any functionally apt interaction between the transporting and working scaffolding on the one hand and the lining setting device on the other, and/or collisions can occur between the section cutting machine and the lining setting machine.

There are moreover known lining setting machines (cf. for example EP-OS 0 037 807) which are mounted entirely on the section cutting machine. On the one hand, these lining setting machines are not mobile to the extent of the lining setting machines to which the invention relates, while on the other hand they colide frequently and particularly heavily with the transporting and working scaffolding.

Accordingly, the object of the invention is to provide an improved lining setting machine of the type initially described, with respect on the one hand to a functionally apt interaction with a section cutting machine and on the other hand to the functionally apt interaction of the transporting and working scaffolding with the lining setting device.

According to the present invention the transporting and working scaffolding on the one hand and the lining setting device on the other hand together form a structural unit arranged to be supported on the cutting arm of the section cutting machine when that arm has been lowered.

There is no permanent connection-which is often a disadvantage-between the transporting and working scaffolding is the lining setting machine and the section cutting machine.

In other words, the transporting and working scaffolding can still, as previously, move relative to the section cutting machine. Consequently, the transporting and working scaffolding can be used to transfer lining sections stored well behind the section cutting machine over the section cutting machine and into the working face area. Thus the invention recognises that the lining setting device of a lining setting machine can interact with a section cutting machine because the lining setting device of a lining setting machine is only required to operate when the cutting arm of the section cutting machine has been operating immediately previously. Thus, in accordance with the invention, a functionally apt iteraction between the lining setting machine and a section cutting machine is ensured.

Provision is thus also made for the functionally apt interaction of the tranpsorting and working scaffolding with the lining setting device. Since the transporting and working scaffolding on the one hand and the lining setting device an the other hand together form a structural unit, better provision is made for the functionally apt interaction of the transporting and working scaffolding with the lining setting device in the lining setting machine of the invention than could be otherwise achieved.

There are various possibilities for further modifying and improving the lining setting machine of the invention in detail, as will be shown below by reference to non-restrictive examples.

Firstly, the transporting and working scaffolding has a recess, preferably open towards the working face, the lining setting device being liftable and lowerable out of or into, or through, the recess in the transporting and working scaffolding. This provides a particularly compact emodiment of the lining setting machine of the invention, which can in this case be readily advanced over the section cutting machine, even when the gallery driven by the section cutting machine is not particularly high.

It is further preferred to provide the transporting and working scaffolding with a seating, preferably having a plurality of seating grooves, for the lining sections, so they they can be set up ready for use on the transport ing and working scaffolding.

The galleries in which operations are to be carried out with the aid of the lining setting machine of the invention can obviously vary in breadth. In order to accommodate this variation the transporting and working scaffolding preferably has laterally extensible widening members (cf. DE-OS 31 09 1 59 and DE-OS 31 09 163, the disclosures in which are hereby expressly quoted as part of the present disclosures).

It might be thought that in principle the height at which the transporting and working scaffolding in the lining setting machine of the invention is set should be specified and invariable. However, it is much more practical to arrange for the transporting and working scaffolding to be raised and lowered hydraulically.

Thus, the transporting and working scaffolding can at one time be lowered behind the section cutting machine sufficiently far to be easily stocked with lining sections and at another time be raised in the area between the working face and the section cutting machine to a height corresponding to optimum operating conditions depending on the height of the gallery.

It is inherent to the lining setting machine of the invention that the transporting and working stage can travel on one or more single-rail overhead tracks. In detail, this can be brought about by having the transporting and working scaffolding attached to a travel slide on the overhead track by a hinged parallelogram mechanism having two longitudinal links disposed side by side in a vertical plane. It is particularly easy to provide hydraulic lifting and lowering means for the transporting and working scaffolding by providing at least one lifting cylinder between the hinged parallelogram mechanism and the travel slide.

It normally suffices for the transporting and working scaffolding to be permanently horizontal. However, it can be useful to incline it under certain circumstances, for example for stocking it with lining sections. With the arrangement just described, which is provided with a hinged parallelogram mechanism having two longitudinal links disposed side by side in a vertical plane, this inclination can be brought about by at least one setting cylinder provided inside the hinged parallelogram mechanism.

It has already been shown that the transporting and working scaffolding in the lining setting machine of the invention can be attached to a travel slide by a hinged parallelogram mechanism having two longitudinal links disposed side by side. Alternatively or additionally thereto, however, the transporting and working scaffolding can be attached to a travel slide on the overhead track by a hinged parallelogram mechanism having two longitudinal links disposed side by side in a horizontal plane.

One means of accommodating to galleries of different breadths has already been described, viz., by equipping the transporting and working stage with laterally extensible widening members. Another embodiment offering the means of accommodation to galleries of different breadths is for the transporting and working scaffolding to be movable across the width of the gallery. This is particularly easily brought about when the transporting and working stage is attached to a travel slide by a hinged parallelogram mechanism having two longitudinal links disposed side by side in a horizontal plane, by means of at least one setting cylinder provided inside the hinged parallelogram mechanism.

The lining setting device in the lining setting machine of the invention is preferably provided with a seating, preferably having a plurality of seating grooves, for the lining sections, so that the latter, which are preferably already set up ready for use on the transporting and working scaffolding, can also be transferred in a ready-for-use alignment on the lining setting device.

It is preferred to provide the lining setting device with a hinged parallelogram mechanism having two longitudinal links disposed side by side in a vertical plane, together with an attachment to the transporting and working scaffolding, and to connect the seating for the lining sections to the hinged parallelogram mechanism and the hinged parallelogram mechanism to the attachment. With this arrangement, the functionally necessary vertical adjustment of the lining setting device, i.e., the seating for the lining sections, can be effected particularly easily by means of at least one lifting cylinder provided inside the hinged parallelogram mechanism of the lining setting device.

Finally, it is preferable for a support bracket to be provided on the transporting and working scaffolding and/or the lining setting device, and a cooperating support pad is provided on the cutting arm of the section cutting machine. Thus, the support brackets may be conveniently part of the attachment for the transporting and working scaffolding to a travel slide on the overhead track by a hinged parallelogram mechanism having two longitudinal links disposed side by side in a vertical plant. The support bracket may be provided with an arcuate supporting face, and a complementary arcuate supporting face is provided on the support pad and on the cutting arm of the section cutting machine, whereby adequate support is ensured for the unit comprising the transporting and working scaffolding on the one hand and the lining setting device on the other hand, even if the line of application of the force through the lining setting device is not vertical.

An embodiment of the invention will not be described by way of example only, with reference to the accompanying drawings, in which Figure 1 is a side elevation of a lining setting machine in accordance with the invention, in conjunction with a section cutting machine driving a gallery in an underground working or a tunnel, the lining setting device being shown lowered and without lining arches being carried thereon; Figure 2 corresponds to Fig. 1, but with the lining setting device shown raised and carrying lining arches; Figure 3 is a plan view of the machines of Figs. 1 and 2; Figure 4 is a fragmentary elevation from the left hand end of Fig. 1 including lining arches; and Figure 5 is a more detailed elevation from the left hand end of Fig. 2.

The lining setting machine 1 shown in the drawings is intended for lining a gallery 2 in underground workings (or a tunnel) driven using a section cutting machine 3; it basically comprises a transporting and working scaffolding 4 with a lining setting device 5 which travel on a single-rail overhead track 6 and is used for the transporting and manipulation of lining sections, such as mine arches 7, the lining setting device 5 being used to set the lining arches 7 in place with force.

As Figures show, the transporting and working scaffolding 4 on the one hand and the lining setting device 5 on the other hand together form a structural unit arranged to be supported on the cutting arm 8 of the section cutting machine 3, when that arm has been lowered.

The transporting and working scaffolding 4 has a recess 10 open towards the working face 9, and the lining setting device 5 can be lifted and lowered out of or into, or through, the recess 10.

The transporting and working scaffolding 4 is also provided with a seating 11 having a plurality of seating grooves 1 2 for lining arches 7, and with laterally extensible widening members 1 3.

The transporting and working scaffolding 4 can be raised and lowered hydraulically, being attached to a travel slide 1 6 on the track 6 by a hinged parallelogram mechanism 14 having two longitudinal links 1 5 disposed side by side in a vertical plane, and a lifting cylinder 1 7 being provided between the hinged parallelogram mechanism 14 and the travel slide 16.

It can be seen particularly clearly from Figs.

1 to 3 that the lining setting device 5 has a seating 1 8 with a plurality of seating grooves 1 9 for the lining arches 7. The lining setting device 5 also has a hinged parallelogram mechanism 20 having two longitudinal links 21 disposed side by side in a vertical plane, together with a pivotal attachment 22 to the transporting and working scaffolding 4, the seating 1 8 for the lining arches 7 being attached to the hinged parallelogram mechanism 20 and the hinged parallelogram mechanism 20 to the attachment 22. A lifting cylinder 23 is provided inside the hinged parallelogram mechanism 20 of the lining setting device 5 so that it can be raised or lowered hydraulically.

Figs. 1 and 2 show a support bracket 24 attached to the transporting and working stage 4 and the lining setting device 5, and also a support pad 25 on the cutting arm 8 of the section cutting machine 3, which bracket 24 rests on the pad 25 when the cutting arm 8 is lowered, the transporting and working scaffolding 4 is lowered, and the lining setting device 5 is raised to set the lining arches 7 in place with force, as shown in Fig. 2.
