Abstract

Verbohrvorrichtung for threshold mounting with a Geraetetraeger that runs on a loesbar mounted on the threshold rail piece with recesses introduced in defined distances, brought in certain positions together with a drag pawl and a Verspannteiles and locked there. For the production of solid surface wells intended for threshold mounting, a rotary impact drilling machine required for these conditions, which is mounted on a pivoting boom, is brought into the respective drilling position at the end of the sleeper. Fig. 1

Description

vertical borehole is made, which creates the condition in the solid ground that a bolt that passes through the threshold into the borehole, can be used. Thereafter, the drill arm is moved 180 ° against the other stop, where the drill at the other end of the threshold also produces the required hole.

When this is done, the tow pawl is lifted, the body of the device is moved until the tow pawl again reaches a recess and engages in it. After appropriate forward movement of the equipment carrier parts of the rail piece, which belongs to the device, solved at one end of the set thresholds and implemented to the other end. The wheels located on the equipment carrier are laterally offset from each other, so that they can pass over the recesses undisturbed.

embodiment

The invention will be explained in more detail below by way of example. In the accompanying drawing mean:

Fig. 1: lateral view of the device in the driving position; Fig. 2: lateral view of the device in drilling position; Fig. 3: view of the device in drilling position;

On the footwall 1 sleepers 2 are placed, which are set in a predetermined position and therefore at the ends

Have holes 3. .

At the thresholds 2, a rail piece 4 is releasably attached. On both rails of the rail section 4 recesses 5 of 0.03 m in length are introduced at intervals of 1.4m from each other. The distances correspond to the distances of the holes 3 in the sleepers 2 from each other. They are offset from the point where the holes 3 are present by 0.50 m.

The rail section 4 consists of individual segments which are releasably connected to each other and with respect to length and arrangement of the recesses 5 are uniform. As required, each segment is released at the end of the thresholds and other segments and fastened again in the direction of travel.

The mobile working part of the device consists of a device carrier?, On the side of each two wheels 8 are mounted.

The right in the direction of running wheels 8 are offset from the two left wheels 8 by 0.08 m laterally. The running wheels 8 of the equipment carrier 7 run on the rails 4 and are guided on it. At the rear portion of the equipment carrier 7, a tow pawl 9 is mounted with snap mechanism on a rotatable attachment 10 which grinds on forward movement of the device carrier 7 on the upper edge of the rail section 4 until appropriately sized hooks (0.03 m length of the latch member), the next Recesses 5 reaches and engage in this. As soon as this is done, sets a Verspannteil 11, which engages under the rail 4a, the device carrier 7 on the rail section 4 firmly. In this position is a perpendicular to the equipment carrier? arranged drill column 12 with its center from the end of the tow pawl 9 as far away as the recess 5 of the bore 3 in the threshold 2, namely 0.50 m. On the drill column 12, a boom 13 is rotatably mounted, which can be pivoted on both sides in the horizontal plane from a central starting position, that stops 19, which mark the middle of the drill column 12 laterally, and stops 20 on the boom 13 meet, whereby the pivoting movement is terminated at this point. When this is done, the drill bit 18 is from drill pipe 17 input to a rotary impact driller 16 which abuts a drill carriage 15 vertically carried in a drill mount 14 attached to the boom 13, each just above a point which is to produce a borehole 21 in the lying 1 through a hole 3 in a threshold 2.

In the driving position shown in Fig. 1, the tow pawl 9 grinds on the surface of the rail head 4c, and the front staggered wheels 8 pass over the corresponding recesses 5. The tow pawl 9 then reaches the next recesses 5, when the drill column 12 comes into place where boreholes 21 are to be bored laterally into the horizontal 1 through the bores 3 in the ends of the thresholds. The drill column 12 with the necessary drilling equipment on the boom 13 is mounted centrally on the equipment carrier 7, whereby the mobile working part of the device has good stability in the driving movement.

Once the tow pawl 9 is engaged in the recesses 5, the Verspannteil 11 performs the locking of the device carrier 7 and connects the rail section 4 and equipment rack 7 to form a unit that represents the entire device.

Thereafter, the boom 13 pivots outwardly until the stop 20 strikes one of the stops 19 on the drill column 12. In this position, the drill 16 performs a drilling operation in which a borehole 21 is made, the depth of which is determined by a stop 22 on the drill mount 14.

After returning the drill 16 to the initial position of the boom 13 is pivoted by 180 ° and performs at the other end of the threshold 2 another drilling operation. Thereafter, the device is returned to the driving position.

For this 3 pages drawings Field of application of the invention The invention is intended to provide conditions that rails for rails can be secured at predetermined locations on high-strength ground, secured against lateral displacement. Characteristic of the known technical solutions The preparation for a threshold fastening on high-strength ground was previously hit by hand-held rotary impact drills. At predetermined locations, short holes were drilled in the vertical direction in the solid ground: In the subsequent laying of the rail track, the thresholds were given a position in which holes in the sleepers coincided with the holes in the deck. By inserting bolts, the thresholds were fixed with the rails attached to them. The processing was done so far only in this way, the disadvantages of which are justified by the fact that the specifications of the starting points for the holes to be introduced should be done with high accuracy and the holes were finally produced successively by hand-held drills. The use of technical means, as they are available from the prior art, was not possible. For example, numerical controls for the execution of drilling programs on their technical complexity and the high degree of sensitivity in use under the specific conditions of the application. The Verbohrvorrichtung known in DE-OS 3017212 has drilling tools arranged on both sides, which can be obtained by twists or displacements of the device a more accurate setting. The arrangement of two similar drilling tools is in addition to the disadvantage of the complexity and complexity of technical training also connected with the requirement to bring both tools as synchronously as possible to use. In addition, the device has in no way a training for automatic entry and detection at certain sites. Object of the invention The aim of the invention is to ensure that to be executed for the attachment of the thresholds at predetermined locations boreholes in high-strength ground when reaching a high accuracy with little time and to a large extent trouble-free. Explanation of the essence of the invention The object of the invention is to provide a device which automatically assumes the necessary for the performance of the necessary Verbohrarbeiten position and executes the corresponding activities when using the required for the given application area rotationally rotating drilling. According to the invention runs on a specially trained, belonging to the device rail piece, which is detachably mounted on the thresholds to be fastened, a mobile equipment carrier on which a rotary percussion drill is mounted centrally on a to both sides against stops by 90 ° pivotable drill arm. On one or both rails of the rail piece recesses are provided at certain intervals, which ensure that when a rotatably mounted on the equipment rack tow pawl with latching mechanism that grinds on forward movement on the upper edge of the rail piece, it engages in them, the equipment rack occupies a predetermined position and is locked in this, in the case of lateral pivoting of the drill arm on reaching the respective deflection a directional vertical or approximately
