Tunneling machine.

In the British coal mining industry these days they are used for propulsion the stretches usually running at the ends of a mining front as the mining front progresses, pushing tools or Impact breakers are used, which, in contrast to others, break open the local impact by pushing or hitting Machines developed for this purpose, which tipped with chisels Carry cutting or prebeads. Both tunneling methods represent alternatives to traditional blasting, in which the Rock is detonated by explosives filled into boreholes.

For loading the debris from the floor of the route onto a conveyor that transports the debris into a corresponding offset space hydraulically driven shovel loaders are often used, However, as an additional machine, they narrow the already cramped space underground even more or with a device according to GB-PS 1 377 899 (DT application P 24 593.44.0) the exchange a shock breaker against a loading shovel and consequently an interruption of the actual propulsion work is necessary do. TJm this constant change from shock breaker to shovel loader and then again from shovel loader to shock breaker off for further dismantling, was in the GB-PS 1 482 375 proposed a shock breaker constantly on a Bucket, but in certain cases the constant presence of the shock breaker can make the bucket work effectively hinder.

The invention has therefore set itself the task of providing a road tunneling machine to create, by means of which the local impact in route or tunnel construction essentially without work interruption broken loose and the accumulated pile can be loaded without affecting the performance of the impact crusher or the Loader bucket is affected.

A tunneling machine according to the invention is identified for breaking loose the local impact in road construction or tunnel construction and for loading the accumulated debris with one on a boom arranged and by means of the same rotatable about its longitudinal axis and with a shock breaker mountable on the shovel essentially in that the shock breaker is in operation

remains on the shovel during loading and from a Working position, in which it points forward parallel to the longitudinal axis of the boom, can be pivoted to the side into a rest position is.

This is how it is with a drifting machine according to the invention possible that the shock breaker is effectively "parked" in a rest or inoperative position in which any Impairment of the operation of the loading shovel is impossible.

The impact breaker is preferably permanently connected to the shovel via an articulated connection and around this articulated connection can be pivoted from the working position to the rest position or vice versa, with a further detachable connection being provided by which the shock breaker can be locked in the working position with the shovel and unlocked for the purpose of pivoting in the rest position is. The shock breaker can either manually or, for example, a hydraulic power drive around its articulated connection be pivoted. If manual operation is desirable, a lock may be required provide through which the shock breaker can be locked in its rest position while the loading shovel is working. Such a one Arrangement may consist of a bolt connection to the loading shovel. When using a hydraulic pressure block this would have to be double-acting and the hydraulic circuit should be designed in such a way that both sides of the pressure block are lockable. The articulated connection and the releasable lock are preferably located at right angles to the longitudinal axis the line running through the shock breaker.

In use, the boom is preferably mounted on an articulated support, as described for example in GB-PS 1 377 809, whereby the impact breaker can come into engagement over the entire surface of the local impact, while the loading shovel preferably around the longitudinal axis of the boom an angle of 360 ⁰ is rotatable.

The articulated support preferably consists of a base, a tower arranged pivotably on the same, and a device to rotate the tower in relation to the base, articulated supports between part of the tower and part of the boom, at least one pressure block hinged to another part of the tower and another part of the boom and one Device for pivoting the articulated supports around their articulated connection with the tower. The boom preferably has a rear part, which is partially rotatable about the longitudinal axis of the boom, a device causing this rotation and one with one end on this rotatable part and with the other end on the loading shovel or a holder thereof attached front part, wherein a pressure block is articulated between this front part of the boom and the tool.

The joint supports preferably consist of two on opposite sides Sides of the tower and the boom hinged supports, while the tower by at least one on him and on Substructure articulated pressure block can be rotated. Preferably, however, two such pressure blocks are provided, which attack both sides of the tower. Preferably there are also two pressure blocks between the tower and the boom

provided, which are also on both sides of the tower and attack the boom.

A pressure bracket is preferably used to pivot the joint supports intended. This pressure block is expediently mounted on the tower. To rotate the rotatable part of the boom A hydraulic motor or another rotary drive such as a rack and pinion drive actuated by a pressure bracket can be provided will. If a hydraulic motor is provided, it can be mounted coaxially with the axis of rotation of the rotatable part of the boom will. Regardless of whether a hydraulic motor or a rack and pinion drive is used, this rotary drive is located at the rear end of the arranged rear part of the boom, i.e. the part that points away from the loading shovel.

Preferably at each end of the rear part of the boom, i.e. next to the rotary drive and next to the rear end of the front boom part, a bearing for the rotatable part intended. In this way, the rear part of the boom can have a circular cross-section, while the front Part of the boom may have a rectangular cross-section.

As a result of the articulated connection of the loading shovel on the front part of the boom and the pressure block connection between the loading shovel and the front part of the boom, the loading shovel can be adjusted to the longitudinal axis of the boom via a Swivel the sector by about 90 °. Due to the adjustability of the pressure blocks, which run between the tower and the boom, can the boom be rotated parallel to the base (if a joint parallelogram is formed) when the joint supports are pivoted

push or through, suitable adjustment of these pressure blocks the position of the boom and thus the loading shovel seated on it in a vertical plane or depending on the angular position of the boom can also be adjusted in other planes. These adjustment options together with the rotatability results high maneuverability for the loading shovel as well as for the shock breaker, so that the corners of a route or a tunnel, which are usually worst to work out can be worked out relatively easily.

This also results for the shock breaker if the pressure block lying between the tower and the boom is set in this way is that this pressure block runs parallel to the joint support, a joint parallelogram, so that when the joint support in the Operation is moved towards or away from the surface to be processed, the angle at which the impact breaker on this Surface attacks, always remains the same.

For the loading shovel, the support according to the invention results in the Possibility to unload the pile to the front, to the side or to the rear.

When the limit of the reach of the articulated support is reached, the substructure must naturally be advanced.

The base can in turn be mounted on a substructure that sits on the bottom of a route or a tunnel can and is advanceable. This substructure can be designed to be self-treading by, for example, this Provides substructure with a known walking mechanism or caterpillar chains.
