Abstract
A tunneling or extraction machine includes cutting tools that are movable over the heading face and are arranged on the boom, and a platform that is movable in the longitudinal direction of the machine and carries roof support devices. The roof support devices include a support manipulator or a supporting device and an anchor-boring and anchor setting device. The anchor-boring and anchor setting device are fastened to the moving platform in a pivotable manner between a parked position and an operating position. The support manipulator or the supporting device has a telescopic arm that is fastened to the movable platform in a vertically pivotable manner, wherein the support manipulator or the supporting device and the anchor-boring and anchor setting device are fastened to the movable platform at a pre-defined, fixed distance apart from one another and are displaceable together with the moving platform between a retracted position and a forwardly displaced position.
Description
- The present invention relates to a tunnelling or extraction machine comprising cutting tools, which are movable over the heading face and are arranged on a boom, and a platform which is movable in the longitudinal direction of the machine and carries roadway support devices.
- Such a tunnelling or extraction machine was known from AT 507495 A1.
- When securing and supporting a tunnelled roadway, usually various types of securing and roadway support devices are provided, wherein, depending on the structure of the rock, in addition to anchor-boring and anchor-setting devices shotcrete manipulators or devices for manipulating and positioning support frames or arches are also required. Conventional tunnelling or extraction machines do not fully meet these requirements, since the different types of roadway support devices cannot be provided at the same time and at a suitable position in a space-saving manner. For example, manipulation devices for support elements, such as support frames or support arches, have been proposed which are separate from the tunnelling or extraction machine. The effort required for roadway securing and support measures is, however, considerably increased by providing separate devices, wherein, due to the constricted available space in the supported roadway, difficulties arise with respect to carrying out the support measures also at a position directly behind the heading face.
- An anchor-boring and anchor-setting device arranged on a sliding track is known from AT 502 047 A4, in which an additional manipulator for lifting and for mounting covering mats is fastened to a rollover of the anchor-boring and anchor-setting device. An embodiment of a support device having two anchor-boring and anchor-setting devices which are pivotably supported on an anchor platform which is movable in the longitudinal direction of the machine is the subject matter of AT 413230 B.
-
DE 29 34 625 A1 discloses a combination of a tunnelling machine with support devices, in which a support manipulator is fixed onto a sliding track, so that pre-assembled support arches can be conveyed along the tunnelling machine and positioned in the roadway in the front area of the tunnelling machine. - In contrast, in the case of the subject matter in
DE 34 13 261 A1, a revolving crane is used which is fixed onto the rear side of the tunnelling machine for lifting up the pre-assembled support arches and for transferring to a support manipulator which can be moved on the sliding track. - A further example for a support manipulator which can be moved on a sliding track can be learned from
DE 29 08 452 A1. - Therefore, on the one hand, the described embodiments relate to the providing of individual roadway support devices in connection with a tunnelling machine, whereby although a specific operation within the scope of the roadway support process can be mechanised and efficiently designed, manual operations are still necessary. On the other hand, the described embodiments relate to multi-functional solutions (e.g. AT 507495 A1), which although they are versatile in their use, in individual cases modifications have to be made, which makes a mechanised method of operation difficult.
- The invention therefore aims to develop a tunnelling machine with integrated roadway support devices further, to the effect that the degree of mechanisation can be considerably increased for a combined roadway support process. At the same time, the individual support devices should be able to be positioned on the tunnelling machine such that the lowest possible headway can be achieved.
- In order to achieve this object, the invention essentially makes provision for the roadway support devices to comprise a support manipulator and an anchor-boring and anchor-setting device, wherein the anchor-boring and anchor-setting device is fastened to the movable platform in a pivotable manner between a parked position and an operating position and the support manipulator has a telescopic arm which is fastened to the movable platform in a vertically pivotable manner and which carries a gripping device for temporarily taking at least one support element, in particular a support arch, wherein the support manipulator and the anchor-boring and anchor-setting device are fastened to the movable platform at a predefined, fixed distance apart from one another and are displaceable together with the movable platform between a retracted position and a forwardly displaced position.
- In a further embodiment of this invention, provision is essentially made for the roadway support devices to comprise an anchor-boring and anchor-setting device and a supporting device assigned to it for the roof, wherein the anchor-boring and anchor-setting device is fastened to the movable platform in a pivotable manner between a parked position and an operating position and the supporting device has a telescopic arm which is fastened to the movable platform in a vertically pivotable manner, wherein the supporting device and the anchor-boring and anchor-setting device are fastened to the movable platform at a predefined, fixed distance apart from one another and are displaceable together with the movable platform between a retracted position and a forwardly displaced position.
- As a result of the anchor-boring and anchor-setting device being pivotably arranged between a parked position and an operating position, the anchor-boring and anchor-setting device can be placed out of the way during heading to save space without hampering the cutting process. In the parked position, the anchor-boring and anchor-setting device is preferably folded-up flat on the movable platform. As a result of the support manipulator or the supporting device having a telescopic arm which is fastened to the movable platform in a vertically pivotable manner, for heading, the support manipulator or the supporting device can be pivoted downwards onto the movable platform, in order to thereby minimise the space taken up. The telescopic vertically pivotable arm of the support manipulator, according to the invention has a gripping device, by which the individual segments or already screwed together multiple segments of the support elements, in particular support arches, are held and brought into the installation position.
- Due to the pivotable and telescopic design of the arm, the gripping device along with the support element temporarily held in the gripping device can be precisely positioned. After the gripping device has brought the at least one support element to the intended position, the support element is mounted as a rule from the bottom up, wherein firstly the props are positioned and the support arch is connected to the previous support arch via spacer bars.
- As a result of the support manipulator or the support device and the anchor-boring and anchor-setting device being fastened to the movable platform at a predefined, fixed distance apart from one another, it is not necessary to set the mutual positions of the two support devices, so that manipulation is made simpler and mechanisation can be improved. The operating position of the anchor-boring and anchor-setting device relative to the support manipulator is in particular chosen such that anchors can be set in the area of the vertical plane defined by the support element positioned by the gripping element. In the case of the supporting device, the operating position of the anchor-boring and anchor-setting device relative to the supporting device is chosen such that anchors can be set in the area of the roof supported by the supporting device.
- In this connection, a preferred further embodiment makes provision for the supporting device to have a supporting plate which can be pressed against the roof.
- In this connection, a preferred further embodiment makes provision for the operating position to be chosen such that the anchor-boring and anchor-setting device and the supporting device in the operating position become effective in an area of the roof located in front of the cutting tools.
- According to a preferred further embodiment, the mechanisation of the roadway support process can be further improved by the roadway support devices further comprising a lifting crane which has a telescopic jib rotatable about a horizontal rotational axis. Here, the lifting crane is preferably fastened to the movable platform at a predefined, fixed distance from the support manipulator or supporting device. Overall, the movable platform carries all essential roadway support devices required for the roadway support process, namely the lifting crane, the support manipulator or the supporting device and the anchor-boring and anchor-setting device. The roadway support process is preferably carried out in such a way that the lifting crane in the retracted position of the platform firstly grips at least one roadway support element, lifts it up, conveys it forwards by pivoting the crane jib and deposits it in a holding device of the gripping device. Then, the movable platform is forwardly displaced and the at least one support element is pressed onto the roof by means of the telescopic arm of the support manipulator.
- In this connection, a preferred further embodiment makes provision for the gripping device to comprise at least one, preferably two, holding pocket(s) for a support element in each case, in particular for a support arch. In the case of one embodiment with two holding pockets, two support elements, in particular support arches, can consequently be brought into the assembly positions at the same time, so that the speed of the roadway support process can be increased. Furthermore, at the same time, the desired distance between two consecutive support elements is predefined by the distance between the two holding pockets.
- If, according to a preferred further embodiment, the gripping device comprises a carrying device, which in particular is arch-like, for temporarily taking a covering mat, at the same time, a covering mat can be positioned by the gripping device or the support elements pressing onto the roof, so that immediately after that the anchor-setting process can be begun.
- In order to increase the stability of the platform, provision is preferably made for the platform to be supported in the upwardly displaced position on a support arranged on the boom.
