Description

Es sind Anzeichnungsgeräte für Rund- und Hohlkörper bekannt, die aus einem Stativ mit Auflageschenkeln sowie aus einer Winkelmeßvorrichtung und einer Markierungsvorrichtung bestehen, z. B. einem Anreißlineal oder einer Ankörnvorrichtung. Mit der Winkelmeßvorrichtung ist zumeist eine Wasserwaage Qder ein Lot so kombiniert, daß mit Hilfe derselben die Abweichung der Einstellung des Gerätes gegen die Horizontale oder die Vertikale ermittelt und abgelesen werden kann. Die Vorrichtungen zum Anzeichnen, wie Schlagdorne od. dgl., ermöglichen die Fixierung der ermittelten oder eingestellten Stellung des Gerätes am Rund- oder Hohlkörper. Insbesondere kennt man eine derartige Vorrichtung, bei der ein Winkel mit einem fixen Winkelmesser verbunden ist, dessen Scheibe einstellbar ist und an dem außerdem ein unter Schwerkraftwirkung in vertikaler Stellung sich einstellender Zeiger angebracht ist. Auch hat man bei derartigen Geräten den Zeiger durch eine Wasserwaage ersetzt, wobei jedoch die Funktionsweise im Prinzip nicht geändert wird.There are marking devices for round and hollow bodies known that consist of a tripod with support legs and consist of an angle measuring device and a marking device, e.g. B. a Marking ruler or a center punching device. The angle measuring device is usually a spirit level Qder combines a plumb bob in such a way that with the help of the same the deviation of the setting of the device against the Horizontal or the vertical can be determined and read. The devices for marking how Percussion spikes or the like, enable the determined or set position of the device to be fixed on the Round or hollow bodies. In particular, such a device is known in which an angle with a fixed protractor is connected, the disc is adjustable and on which also a gravity in a vertical position adjusting pointer is attached. One also has with such Devices replaced the pointer by a spirit level, but the mode of operation did not change in principle will.

Die bekannten Anzeichnungsgeräte für Rund- und Hohlkörper sind in der Handhabung kompliziert; so ist es erforderlich, bei der Anzeichnung eines gewissen vorgegebenen Winkels an einem Rund- oder Hohlkörper zunächst den Ausgangspunkt festzulegen, dann das Gerät einzustellen, indem die Winkelteilscheibe verstellt wird, dann das Gerät neu anzusetzen, und zwar durch umständliches Probieren so anzusetzen, bis der durch Schwerkraftwirkung eingestellte Zeiger oder die Wasserwaage die vorgegebene Stellung anzeigt. Derartige Manipulationen sind umständlich und beeinflussen auch die Meßgenauigkeit. Darüber hinaus besteht bei den bekannten Geräten ein wesentlicher Nachteil darin, daß die Anordnung stets so getroffen werden muß, daß der Schwenkkraftzeiger oder die Wasserwaage arbeitet, d. h., die Rohrleitungen müssen genau waagerecht oder genau vertikal verlaufen und die Geräte entsprechend aufgesetzt sein.The known marking devices for round and hollow bodies are complicated to use; so it is necessary when marking a certain predetermined angle on a round or hollow body first set the starting point, then set the device by adjusting the angle dividing disk is, then to set up the device again, namely through cumbersome trial and error, until the Pointers adjusted by gravity or the spirit level shows the preset position. Such manipulations are cumbersome and also affect the measurement accuracy. Furthermore there is a significant disadvantage in the known devices that the arrangement is always made in this way must be that the slewing force pointer or the spirit level works, d. i.e., the piping must run exactly horizontally or exactly vertically and the devices must be put on accordingly.

Die Erfindung hat sich die Aufgabe gestellt, ein Gerät zu entwickeln, das eine einfache Handhabung zur Anzeichnung eines Winkels an beliebig verlegten Rohren, vor allem auch an schräg verlegten Rohren, zuläßt dabei sollen bekannte Anzeichnungsgeräte für Rund- und Hohlkörper baulich und in bezug auf ihre Handhabung wesentlich vereinfacht werden.The invention has the task of developing a device that is easy to use Marking of an angle on any pipes laid, especially on pipes laid at an angle, allows known marking devices for round and hollow bodies structurally and in be significantly simplified with respect to their handling.

Die Erfindung betrifft ein Anzeichnungsgerät für Rund- und Hohlkörper aus einem Stativ mit Auflageschenkeln und/oder Führungsschenkeln sowie Winkelmeßvorrichtung und Markierungsvorrichtung.The invention relates to a marking device for round and hollow bodies from a stand with support legs and / or guide legs as well as angle measuring device and marking device.

Nach der Erfindung ist ein derartiges Anzeichnungsgerät gekennzeichnet durch eine mittels auf der Fläche des Rund- oder Hohlkörpers bei Schwenkung des Ge-Anzeichnungsgerät für Rund- und Hohlkörper According to the invention, such a marking device is characterized by a means on the surface of the round or hollow body when the Ge marking device for round and hollow bodies is pivoted

Die durch die Erfindung erreichten Vorteile sind darin zu sehen, daß es nicht mehr erforderlich ist, in umständlicher Weise am Gerät Einstellungen vorzunehmen und beispielsweise eine Wasserwaage abzulesen, um festzustellen, ob der vorgeschriebene Winkel erreicht oder ein zu messender Winkel genau eingestellt ist, sondern das Gerät nur auf Rund- oder Hohlkörper aufgesetzt zu werden braucht und dann nach einfacher Schwenkbewegung in Richtung eines Hohlkörperumfangskreises von der Ausgangsstellung am Gerät der Schwenkwinkel abzulesen ist.The advantages achieved by the invention can be seen in the fact that it is no longer necessary in laborious way to make settings on the device and read off a spirit level, for example, to determine whether the prescribed angle is reached or an angle to be measured is precisely set is, but the device only needs to be placed on round or hollow bodies and then after simple pivoting movement in the direction of a hollow body circumferential circle from the starting position on The swivel angle can be read off the device.

Um auf einfache Weise die erfindungsgemäße Vorrichtung verschiedenen Durchmessern der Rund- und Hohlkörper anpassen zu können, empfiehlt es sich, eine Dreipunktauflage für das Gerät vorzusehen, bei der beispielsweise die drei Auflagepunkte nach Aufsetzen auf einen Rund- oder Hohlkörper diesen längs eines Umfangskreises berühren. Durch die Dreipunktauflagerung, die bekanntlich jeweils einen einzigen Krümmungsradius genau festlegt, läßt sich das Gerät verschiedenen Durchmessern anpassen, so daß durch Verstellung der Dreipunktauflagerung bzw. Dreipunktführung zugleich und die Winkelmeß vorrichtung dem durch die Veränderung der Dreipunktauflage sich verändernden Krümmungsradius angepaßt werden kann. Beispielsweise kann eine Dreipunktauflagerung aus gespreizten Schenkeln und zweckmäßig mittig dazwischen angebrachtem, den dritten Auflagepunkt bildenden, höhenverstellbaren Antriebsrad für die Winkelmeßvorrichtung benutzt werden. Die Übertragung der Bewegung des Antriebsrades kann vorzugsweise über Kegelräder auf ein Reibradgetriebe erfolgen, wobei einem großen tellerartigen Reibrad ein von dem Antriebsrad angetriebenes, senkrecht gegen die Teller-To easily the device according to the invention different diameters of the round and To be able to adjust hollow bodies, it is advisable to provide a three-point support for the device for example, the three support points after placing it on a round or hollow body along this length touch a circumference. Due to the three-point support, each of which is known to be a single one Defines the radius of curvature precisely, the device can be adapted to different diameters, so that through Adjustment of the three-point support or three-point guide at the same time and the angle measuring device the changing the radius of curvature can be adapted by changing the three-point support. For example, a three-point support can consist of spread legs and expediently in the middle between them attached, the third support point forming, height-adjustable drive wheel for the angle measuring device to be used. The transmission of the movement of the drive wheel can preferably be via Bevel gears take place on a friction gear, a large plate-like friction wheel being one of the drive gear driven, vertically against the plate

surface of the first-mentioned friction wheel attached and assigned to rolling friction wheel, which can be adjusted in height together with the drive wheel, while the plate-like friction wheel is fixed in a receiving housing; the plate-like friction wheel, for its part, preferably drives a disc which is divided into 360 ° and on which the pivoting angle can be read. In this embodiment, the radius of curvature is increased by extending the distance between the drive wheel and the crossing point of the support leg, which is defined by the three points and which corresponds to the round or hollow body to be processed, on which the device is placed in three-point support. If the distance is shortened, the situation is reversed. All that is required is simple dimensions of the friction wheels rolling on one another in order to adapt the angle display to the change in the radius of curvature. The adjustment to different radii of curvature can also be made in that the expansion opening is adjustable in the case of a three-point support with spread support legs, whereby the device can be placed on round or hollow bodies of different diameters by adjusting the expansion openings. In all embodiments of the device according to the invention, it is advisable to ensure that after lifting the device or after completing a measurement, the angle measuring device automatically moves back into the middle position, which z. B. can be done by springs. Of course, the device is to be provided with marking devices, for example rulers or devices for punching in, such as firing pin devices, which do not need to be described in detail. The advantages achieved by the invention consist, in addition to those already mentioned, in the fact that a controllable adaptation to different diameters of round or hollow bodies is possible in a simple manner even when using a friction gear. In order to avoid measurement inaccuracies, the devices are designed so that they can only be used for a specific diameter range of the round or hollow body, for example from 200 to 500 mm or from 500 to 700 mm. The equipment also improves the accuracy of the assembly of pipelines, and it also saves manpower, e.g. B. otherwise have to go to the fitter to handle the marking device when laying pipelines.
