Hole splitter for stone wall drilling

The invention relates to a hole spacing device for drilling a row of holes in a stone wall, such as concrete, rock, stone or the like, by drilling a plurality of successive holes, the hole spacing device being arranged in a drilling apparatus comprising a body supporting the drilling device. a guide in the arrangement to be moved by means of transfer means and at certain intervals in said direction to be locked in position by means of locking means, the drilling taking place in periodic successive The hole spacing distributor 20 according to the invention is particularly suitable for use in high-precision drilling, such as row drilling, groove drilling or the like.

:. ·. The distance between the holes to be drilled is determined. 25 in many ways: visually, by measurement or by a mechanical or numerically controlled distributor.

Of the above methods, the visual method is inaccurate, as is the measurement method, which is also difficult to apply in practice. Devices based on numerical::: control are expensive and also require special expertise from both service and operating personnel. In addition, such devices are. When used in demanding conditions, their reliability is questionable, for example due to fine rock dust. Since the majority of quarries still use pneumatic drilling rigs that do not otherwise use significant electronics or numerical control, a mechanical solution is usually the only practical option.

5 Existing mechanical solutions are based on the so-called for the use of a long busbar, which is expensive and cumbersome to install. Such a distribution rail comprises a guide rail mounted longitudinally on the body of the drilling rig, with successive holes into which the drilling rig is locked in successive drilling positions. The disadvantage of such a dividing rail is also that when changing the hole spacing, the entire rail has to be changed. Thus, such devices are mainly intended for drilling in a certain hole spacing, whereby changing the hole spacing is both technically and economically disadvantageous.

On the other hand, U.S. Pat. No. 3,313,355 discloses an apparatus different from the subject matter of the present invention, i.e. stone wall drilling, in which, however, there are certain structural similarities with the present invention. The apparatus disclosed in the publication comprises a body supporting the actuator, in which the working device is arranged to move in a unidirectional guide arrangement by means of transfer members. In addition, the implement is arranged at certain intervals in said direction to be stopped in successive positions by the co-operation of the positioning members (sprocket) and the transmission members (transmission chain). However, no locking means connected to the positioning means have been used for positioning successive working positions, which at the same time cause the locking of the implement to be immobilized at the time of stopping, which is necessary for the present invention due to its intended use.

The purpose of the hole splitter according to the present invention is to provide a decisive improvement over the above-mentioned drawbacks and thus to substantially increase the state of the art in the art. To achieve this purpose, the hole splitter according to the invention is mainly characterized in that the locking means are arranged at least in a data-transmitting connection with the hole splitter, whereby the drilling device locks at the same time when it stops in the drilling positions.

The most important advantages of the hole splitter according to the invention are simplicity, reliability and accuracy, which are especially important in a demanding work environment. In this case, the hole splitting device according to the invention is advantageous both in terms of its manufacture and installation, whereby it is also possible to vary the spacing of the holes to be drilled.

Other dependent claims disclose preferred embodiments of the hole splitter 20 according to the invention.

In the following description, the invention will be illustrated in detail with reference to the accompanying drawing, which shows a preferred embodiment of a hole splitter according to the invention.

The hole spacing divider is intended for drilling a row of holes 2 in a stone wall 1, such as concrete, rock, stone 30 or the like, by drilling several successive holes therein. The hole spacing distributor 9 is arranged in a drilling apparatus comprising a drilling device 5. · ': a supporting body in which the drilling device 5 moves in a guide arrangement 6 in the SI direction by means of transfer members 7 35, the drilling device 5 locking at certain intervals in the SI direction by locking means 8. Drilling takes place in the drilling device 5 in successive drilling positions by means of a pressure-mediated, electric power plant, electric power supply, etc. The hole spacing distributor 9 operates by means of transfer members 7, whereby the locking members 8 lock the drilling device 5 in the drilling positions.

In the embodiment shown, the bore gap distributor 5 according to the invention has a guide placed in the arrangement 6 on a movable carriage 5a, which moves by means of transmission members 7 10 consisting of a sprocket arrangement 7a acting as a transmission arrangement and a motor acting as a power member. The bore spacing distributor 9 comprises mechanical members 11 operating in connection with the transmission arrangement 7a, following the movement 15 in the transmission arrangement 7a, comprising a wheel 11a acting as a moving member in connection with the transmission arrangement 7a and two holes 11b acting on the side surface of the wheel.

20

The locking members 8 comprise a locking arm 8a in connection with the wheel 11a, which is fastened in the first freedom direction by means of fastening means 10 to the carriage 5a. The fastening members 10 comprise a spring acting as a load element acting in the respective freedom direction, by means of which the pin 8al in the locking arm 8a is in the drilling position of the drilling device 5 in one of the holes 11b of the wheel 11a, the chain 7a and the wheel 11a. After drilling the hole in the drilling position, the pin 8al of the locking arm 8a is removed from the hole 11b in the wheel 11a, after which the movement of the chain 7a can continue and the carriage 5a can move. Locking takes place again in the so-called. automatically at a certain distance 35, in the next drilling position, whereby the locking arm 8a locks the wheel 11a again.

.: q ς 7 c 5 0 - · '^ In practice, the hole gap divider 9 shown as a preferred embodiment is also suitable for use when drilling a row of holes 2 in two stages. In this case, the first holes 3, 5 are first drilled in the direction S1, after which the second holes 4 are drilled between the first holes 3. The mechanical members 11 following the movement in the transmission arrangement 7a comprise a mechanical control member 11c arranged in connection with the wheel 11a. 4 in the direction SI with respect to the first holes 3.

In this case, the mechanical adjusting member 11c connected to the wheel 11a operates in such a way that it changes the mutual locking position of the chain 7a of the wheel 11a and 15. The mechanical adjusting member 11c is formed so that the locking arm 8a can be locked in, for example, two positions relative to the carriage 5a. In this case, for example, in the position of the locking arm 8a according to the drawing, the first holes 20 3 are drilled, after which the washer 11c, to which the locking arm 8a is fixed to rotate freely, is turned 180 °, whereby the locking arm 8a is tilted in the other direction. With this arrangement, the second holes 4 are arranged, for example, centrally between the first holes 3.

In its simplicity, the hole spacing distributor 9 according to the invention operates in such a way that the holes 11b in the wheel 11a interlock with the locking arm locking pin 8a in certain drilling positions on the carriage 5a in the chain 7a, whereby the locking pin 8a After drilling 35, the locking is removed by removing the locking pin 8a from the hole 11b, after which, when the wheel 11a rotates with the chain 7a, locking takes place again in the so-called automatically on the next wheel 11a at hole llb.

Thus, the hole splitter according to the invention makes it possible to easily change the hole spacing, since it can be realized, for example, by changing the wheel 5 11a to another wheel in which one or more holes 11b have different diameters. Of course, the hole spacing can also be changed by adding or removing holes 11b.

The hole splitter according to the invention is particularly suitable for use, for example, in a drilling apparatus according to the applicant's parallel patent application, entitled "Method and drilling apparatus for drilling a row of holes".

15

It is clear that the invention is not limited to the presented application, but can be considerably modified within the framework of the basic idea. Of course, it is possible to simply arrange the operation of the locking elements 20 for automatic treatment or for operation with electrical and optical actuators, in which case, however, the use and maintenance of the device in practice requires greater professionalism. In this case, however, it is not possible to implement a device corresponding to the application shown, for example, from the point of view of overall consistency, which is substantially cheaper in terms of manufacturing costs than the current solutions.
