Description

The invention relates to a device for introducing expansion parts, in particular expansion arches in underground mining stretches, with two parts to be hung up on already standing parts, Advance deposit rails that can be advanced in the direction of advance and extend over several construction distances for placing the new expansion parts to be introduced and with at the front ends of the Rope pulleys arranged in advance of pawning rails, over which a two-strand rope pull with attached grippers for the newly installed expansion parts laid out on the floor. Devices of this type are known (German Auslegeschrift 704 and British Patent Specification 1 093 288).

In the known devices, the two pre-pledging rails are on the extension parts that are already in place suspended by means of a plurality of pre-pledging hooks and in these pre-pledging hooks independently of each other, each can be advanced and clamped for itself. Due to the lack of it from cross connections between the two pre-pledging rails to inevitably common feed movements the parallelism of the rails during and at the end of their feed movement is not guaranteed. Furthermore, it is not guaranteed that that both rails are advanced equally far. It is therefore to be expected that after the Clamping the respectively advanced pre-pledging rails their ends and those arranged on them Pulleys one of theirs on a case-by-case basis

All of this is in the first place of a single roof arch when it is raised safe heaving up and placing of the new level to be added around its suspension point in a position bringing expansion parts could level out at the ends of the two 5, in which he of the Oreüern ae Pre-pledging rails detrimental. The disadvantage of the lifting device for lifting the unknown Devices are also provided in the second stage, not even components the leadership of the two pre-pledging rails in the would be recorded. Otherwise this is ^ well-known individual pre-pledging hooks.

17 two rollers 22 are mounted, which protrude over the two of the one 25 on the carriage 16 directly and the one on the longitudinal sides of the carriage 16. This roller 26 indirectly projects into the profile chambers of the I-shaped 25 ger2 of the pre-pawn frame via a guide roller 1 of the pre-pawn frame 1, 2 and 27 engages in it. The front ends of the Vorpfändehaben between the upper and lower inner flange rails 1 are attached parts 28, in which see the I-shaped frame side member 1 such a continuous axis 29 is mounted, the large play that between the Vorpfandrahmen 1, on the outside of the rail ends protrude-2 and the carriage 16 a possibility of movement 30 the ends of rope pulleys 30 sit. There is also a vertical direction over the pulleys. At an already 30, a two-strand cable pull 31 is guided, to which the stationary extension arches B clamped slide grippers 32 for the extension parts B laid ready on the lying, newly inserted and lowered opposite it, from which extension parts B are attached. The gripper building arches B detached pre-pledging frames 1, 2 according to 32 are designed as hooks that correspond to the profile of FIG. 1 and 3, the pre- pledging frame with the built-in parts B is adapted and by means of a spacer 33 connecting its longitudinal members 1 to the rollers at a distance from one another 22 of the carriage 16, so that it is held on the rollers 22 on the other, which can be moved forward slightly in accordance with the spacing of the grooves. If, on the other hand, the pulleys 30 at the end of the pre-pledging rails 1 according to FIG. 4 corresponds to the existing expansion arches B. The cable strands 31 are clamped by the ropes pre-pledging frames 1,2 and the carriage 16 released from 40 rolls 30 on the outer sides of the pre-pledges B in a position lowered along it rails 1 across further cable pulleys 34, so the carriage 16 sits at the rear led to a winch.

The add-on parts 28, which are in front of the slide 16 opposite the Vorpfänderah- 45 rail ends, can be easily moved in men 1, 2. The guide surfaces 22 of the slide 16, which rise at an incline in the direction of the cable pull, are made of a synthetic material for the forwarding of the high-strength material to the cable pulleys 30, so that the longitudinally moving gripper hooks 32 and extension parts B can act on the movements, be it the Carriage 16 or the front ends of the rails 1 of the pre-pledge frame.

The cable 31 could also be longitudinally displaceable in the slots 9 with regard to several gripper hooks 32 at intervals one behind the other in their mutual position of the respective structural spacing, so that several can be adapted to the lying beden. The ability to adapt, newly introduced extension parts, at the same time the possibility of the device being heaved under extension arches and on the pre-pledging rails 1 in different radii, is ensured by the fact that 65 desired structural distance from one another is placed on the slide longitudinal profiles 17 - as in FIG.
