Problems solved by technology

However, switching between the drilling position and the bolt setting position is only cumbersomely possible, and other disadvantages related to the size of the components also arise
The components for bolt setting must therefore have correspondingly large dimensions, in which the use of such devices is problematic with regard to manufacturing and operating costs and also to the narrow site conditions

Embodiment Construction

[0036] figure 1 A device 1 for setting rock bolts is shown together with units and components related to the invention. These are above all the trolley support means 2 which function to receive the drilling trolley 3 and the bolt setting trolley 5 . It can be clearly seen that the drilling jumbo 3 is designed to be much bulkier than the bolting jumbo 5 . The two rigs are set at a 90° offset from each other so that the drilling rig 3 is figure 1 In the shown position it lies in the drilling axis 14 , while the bolt setting carriage 5 is positioned laterally to the drilling carriage 3 . The pivot mechanism 7 with the hydraulic cylinder not visible here is in the retracted position. If the drilling slide 4 of the drilling jumbo 3 is moved in the form of a rotary and / or percussion unit in the direction of the front end 15 of the device 1 , the correspondingly high forces necessary to form the borehole can be applied. The guide 12 at the front end 15 of the device 1 and the bac...

Abstract

The invention relates to a device (1) for setting a rock bolt, comprising a drilling carriage (3) that is located on a carriage support (2). The device (1) is equipped with a pivoting mechanism (7) between an upper part (23) and a lower part (22) of the carriage support (2), by means of which mechanism the carriage support (2) can be moved between a drilling and a bolt setting position. The carriage support (2) is also equipped with a separately driven bolt setting carriage (5) that is smaller in size and is offset by approximately 90° in relation to the drilling carriage (3).

Description

technical field [0001] The invention relates to a device for setting rock bolts (Felsanker), which has a support device arranged on a trolley Drilling jumbo (Bohrlafette). Background technique [0002] Such devices are used in safety structures in tunnels, mining or underground works (Tiefbau). The anchors here take on multiple functions such as tension elements to hold the structural arch in place. Improve the supporting role of mountains or prevent lateral movement of stones in the environment. The usual form is anchoring in one step or in three steps (das Ankern). With one-step anchoring, self-drilling bolts filled with adhesive are placed in rock in only one operating step. A disadvantage of such self-drilling bolts, apart from the high price, is that percussion drilling is not possible with this technique. In the three-step method, the boreholes are first formed individually. The adhesive is then manually pushed into the borehole; finally, the bolt is manually p...
