Arrangement for parking a drill carriage movable on rails in a pit of little profile

The invention relates to an arrangement for parking a drill carriage that can be moved on rails for the purpose of release of the working area in pits with a small profile, the drilling trolley with the drilling rig on a two pairs with wheels provided pivot arms supporting chassis is attached and the chassis has a horizontally pivoting cross member has, one end of which is firmly connected to the jacket of a telescopic Spreizsäulo.

Drill jigs with parking arrangements currently in use have a number of disadvantages. It is that their taxes are cumbersome and tedious

Interventions are used. Drilling equipment currently in use and arranged on this car allowed only a short, ineffective intervention to drill funnel openings in narrow passageway profiles. Placing such cars from the track could be mechanized only partially, not all conditions for w protect the operator were met.

The invention is based on the object of designing an arrangement of the type mentioned at the outset in such a way that it a highly mechanized parking, the use of modern drill arms for drilling parallel boreholes and Enables increased operational safety when transporting the drill carriage on a narrow track.

This object is achieved according to the invention in that the chassis as a more rigid horizontal to its Center rotatable carrier is formed, over which also if rotatably a vertical frame is mounted on one side at least one drill and on the other side one end of the horizontally pivotable cross member carries, the pivotable cross member and one parallel thereto, on the one hand from a console of the vertical frame and on the other hand, carried by a vertical guide rod held by holders of the expansion column Form parts of a parallelogram »

The pivotable cross member is preferred according to the invention rotatably coupled to the vertical frame by means of a hydraulic adjusting cylinder, and the like

is the vertical frame with the rigid support means a hydraulic rotary cylinder coupled die swiveling Arms of the chassis are preferred according to the invention controlled by arms hinged to two pairs of tie rods, which in turn are attached to each other opposite ends of parts of a hydraulic cylinder that move in opposite directions, which is mounted freely in the space between the two axes of rotation of the pivotable arms, are articulated.

The main advantage of the arrangement according to the invention is a good interaction of all operations carried out by such an arrangement for parking a drill carriage movable on tracks are required.

The new vertical frame enables the use of modern drill arms for drilling parallel drill holes with effective deep intervention. The new arrangement of a chassis with a combination of swiveling wheels with a cross member guarantees the safety of the operator when transporting the drilling rig, even on narrow tracks and when the center of gravity of the arrangement is high · By mechanizing everything associated with parking the drill rig Functions are eliminated, manual labor and security and a substantial shortening of this operation achieved.

The drawing shows an exemplary embodiment and the individual phases in which the arrangement according to the invention is used shown for parking the drill carriage} includes:

The arrangement for parking a drilling carriage according to FIGS. 1 and 2 consists of a horizontal rigid support 1 which is supported during transport by two pairs of pivotable arms 2 provided with wheels 3. Provided on the rigid support 1 is a vertical frame k which can be horizontally rotated about its center and on which, on one side, for example, two drilling devices 5 for drilling known parallel boreholes can be rotated about a horizontal axis

are attached. At one end of the upper part of the vertical frame h , a horizontally pivotable cross member 8 is mounted by means of a vertical pin 7 carried by two brackets 6, and to the other end of the cross member 8 a vertical jacket 9 of a known expanding column 10 is attached. This expansion column 10 can be telescopically extended by means of a piston rod 11 (FIG. 3). A bracket 12 is attached to the vertical frame k at the level of the cross member, to which a pull rod 14 pivotable about the Aohse is articulated, which at the other end carries a sleeve 15 for the purpose of slidable guidance on a guide rod 16, which at both ends by on the expansion column 10 attached holder 17 is carried. The longitudinal axis of the pivotable cross member 8 and the tie rod Ik form a parallelogram with the pivot points of the axis 13 »of the sleeve 15» of the pin 7 and the Ve.rtikalaohse of the expansion column 10, which is controlled by the hydraulic adjusting cylinder 18 (Fig # 2), for which it is attached with its piston rod to the fixed bracket 19 of the vertical frame h and with the cylinder end to the pivotable cross member 8 via the bracket 20 »

Set direction movable working elements, that is, on the cylinder and on the piston rod, pivotable Pair of tie rods 25 »26 with fixed arms 27, 28 is attached. Both ends of the rigid beam 1 are hydraulic Lifters 29 are provided with support plates (Fig. 2),

In the transport position (Fig. 1 and 2) the pivotable cross member 8 is parallel to the longitudinal axis of the track, as is the one or more drilling devices 5 * The horizontal rigid carrier 1 remains in its transverse position, with the spreader column 10 being raised and the hydraulic ones of course Lifter 29 with the support plates are retracted. Upon arrival of the drill carriage at the work place the entire assembly by means of the hydraulic jacks 29 and the Spreizsäule is lifted above the track 10, whereupon duroh means of the hydraulic ZylindBrs Zh within the rigid support 1, the pivotal arms 2 with the wheels 3, the pair of tie rods 25 be rotated parallel to the rigid support 1, that is, outside of the track in the position 2, 3 »26 with the arms 27 28 (Fig. 2) _e After completion of the Bohrabeiten the pivotal arms 2 with the wheels 3 are reversed work of hydrauliaohen cylinder Zh brought over the track and lowered the ganae arrangement by pulling in the hydraulic jack and the spreader column 10 on the track. The entire arrangement is moved to a selected safe place and parked from the track to the side of the aisle for the purpose of clearing the work space as follows (Fig. 5) Spreizaäul · 10 is spread between the sole and the Deoke, into which a pre-

drilled opening an anchor support 3 ^ was inserted, and fixed in this position by means of an expansion sleeve. Then the whole assembly is lifted by supplying a pressure medium into the vertical wall 9 of the Spreizsäule 10 'the swingable arms 2 with the wheels 3 are in the above described manner in the position 2', adjusted 3 ^f and the rigid support 1 by means of the hydraulic Cylinder 21 rotated by 90 °. The arrangement prepared in this way is now parked by means of the hydraulic parking cylinder 18 to the side of the aisle (Fig. 4), the parallelogram t pivoting carrier 8 - holder 17 - axis 13 of vertical pin 7 during this movement the drilling device 5 on the vertical frame k always in a position parallel to the track axis and thus also to the corresponding aisle wall.
