CS264214B1 - Device for capturing the force reaction for metrological control of balances - Google Patents

Abstract

This is the capture of the force response during metrological control of the balance by a special device. The principle is that the device can only be attached to open steel profiles of the base frame and is adjustable so that the vertical axis of the load element can be adjusted vertically in both planes. The solution will be used wherever metrological control of metrological inspection of instruments will be carried out, for base frame scales of open profiles that do not have a lever mechanism in the housing.

Description

The invention solves the problem of capturing the reaction of the force exerted for the purposes of metrological control of weights by the loading elements of the metrological control device whose base frame is made of U-profiles and the lever system is not placed in the housing.

At present weights of weight are used for metrological control of weights. Before carrying out the check by means of a weight standard, it is necessary either to weigh the balance, which in particular does not have a simple load surface; or often dismantling downstream technology, which results in high downtime in production and considerable dismantling and assembly costs, with a high risk of injury and hygienically harmful work.

The weight of the standards to be placed on the scale is about 1.5—41, which in technical terms brings a number of problems that often reduce the accuracy of metrological verification at work.

For metrological balancing we use a new instrument for metrological balancing. For its operation, this device requires the use of a force reaction capture device, the type of which is governed by the design of the controlled weight.

Without special types of these devices for the individual design of the balance, the use of the metrological check device is impossible.

The aforementioned drawbacks are eliminated by the device for capturing the force reaction during the metrological check of the balance. It is based on the fact that the reaction of the force used to check the scales is absorbed by the open steel profile scales at the scales where the lever system is not located in the housing.

The advantages of a force response capture device for metrological weight control are that it primarily allows the use of metrology control devices

A force response capture device for metrological weighing control characterized in that attachments (5A, 5B) with lever pins (3) on which the weighing devices are rotatable are attached to the weighing base frame (2). Without this device, this method of inspection is not possible with scales whose base frame is made of U-profiles and the lever system is not placed in the housing. Furthermore, it is possible to eliminate the laborious work of metrological inspection of the scales with weight standards, eventually difficult dismantling and re-assembly of the interfering technological equipment.

The device allows to align the axis of the applied force of the loading element with the axis of the force acting in the normal state of weighing the dosed material (outside the metrological control process).

The device is portable and can be moved to another location with the same type of scale after performing metrological inspection.

The advantage is also the saving of material compared to the stable design, which would have to be attached to each scale separately.

The device according to the invention is shown by way of example in the accompanying drawing, in which Fig. 1 is a side view of the scale and Fig. 2 is a plan view.

During the metrological inspection of the balance, attachments 5A, 5B are attached to the steel profiles of the base frame 2 of the balance. On the handles 5A, 5B, longitudinally adjustable levers are mounted movably by pins 3

4. The two other ends of the levers 4 are in an articulated connection 8 connected to each other and to one end of the load element 7, the other end of which is movably fastened in the support bracket 6 of the weighing device 1.

By moving the handles 5A, 5B over the open profiles of the base frame 2 and simultaneously adjusting the length of the adjustable levers 4, the vertical position of the force axis exerted by the load elements 7 acting on the load device 1 is adjusted. Thus it is possible to carry out the load of the balance for the purposes of metrological control by the load elements 7 instead of the weight standard.

Claims (1)

Adjustable levers (4) are provided, which are connected in a hinged connection (8) to the load elements (7), which are movably mounted in support brackets (6) on the load device (1) of the balance.
