Definitions

• the present invention relates to a remotely manageable vibration measuring device according to the preamble of claim 1, which is particularly suitable for use in places that are difficult to access.
• vibration measurements are required at a number of points, for example on the coolant inlet and outlet lines, which must be carried out before commissioning and therefore not subject to radiation, but nevertheless with the system fully assembled.
• the measuring locations selected for the measurement and prepared, for example, by the installation of suitable contact surfaces for the measuring devices can often only be reached with the aid of so-called measuring lances, in the head of which the measuring devices are arranged and which are passed through corresponding channels, gaps or the like
• the application of the invention is not limited to this use, which is given as an example.
• the object of the present invention is a remotely manageable device for vibration measurement, which can be positioned securely and whose resonating mass is kept as low as possible. As a result, the spring force required for pressing the measuring device is kept very low at high frequencies.
• non-rigid connections are primarily cables for the supply of energy to the measuring devices and the derivation of the measurement data obtained from display devices, memories, etc., which take into account the desired minimization of the resonating mass of the
• Measuring device can be arranged separately from this. This mass is reduced to the lowest possible level by the fact that the handling device is decoupled from the actual measuring device in terms of vibration for the duration of the measuring process.
• the means proposed in the third claim are used to make the installation and removal of the measuring devices at the measuring location easy to perform remotely.
• the individual measuring devices are set up to absorb vibrations in different directions, for example three Devices in the X, Y and Z directions.
• Figure 2 shows the upper part of an axial longitudinal section
• Figure 3 shows a cross section along the line I - II.
• the vibration behavior is to be examined, for. B. created a cylindrical channel 2, in which, as shown here, a corresponding measuring device can be inserted.
• This consists of two measuring devices 3, each consisting of one
• the measuring devices 3 are brought by means of a tubular measuring lance 8 of greater length, which is provided transversely to its longitudinal axis with two openings 81 through which the clamping pieces 31 pass outwards the outline of the measuring probe 8 can step out and, as shown here, adjoining opposite sides of the channel 2 bracing each other so that the measuring devices 3 also remain in their position without further attachment when their connection to the measuring probe 8 is released.
• the clamping device 6 consists in particular of two claws 61 which press on the abutments 71 on the outside and which are articulated on a flange 64 in the interior of the measuring lance 8; likewise articulately engage a lever 62 on the claws 61, which are hinged at their other end to a pull rod 63 which is guided upwards in the measuring lance 8.
• an adjusting nut 65 can be turned, for example if it is turned clockwise, the pull rod 63 is pulled upwards and the levers 62 are deflected in such a way that they engage the claws 61 the abutment 71 press and so compress the spring 7.
