Description

For reproducing force values with great accuracy in metrology, installations with direct loading of model weights on a cargo rod are used.

The described device is more perfect in comparison with the known devices of this kind, since it allows to dry out, load and unload the loading bar according to any program.

This is ensured by the fact that the device employs a pair of annular cross-arms movable in the vertical direction and equipped with gates, of which the upper one serves to support the overhead, their weights, and the lower one lowers the lower weights onto the pallet of the cargo rod.

The drawing shows a schematic diagram of the device.

It contains two annular traverses I and 2, of which the upper serves to support the overlying weights 3, and the lower one to lower the lower weights 4 onto the pallet 5 of the load rod 6.

The traverses can be stirred in the vertical direction along the guide screws 7 suspended from the top plate 8. In each traverse there are retractable gate valves 9 that can enter the pockets 10 of each weight.

In the center of the weights there is a hole for the passage of the cargo rod.

In the initial position, all the weights lie on the gates of both traverses. In this case, the top load is pressed against the stop 11 and the cargo rod is free from load.

Pushing in and out of the gates and moving the cross arms along the spindle screws is carried out with the help of an electric motor.

In the device, several groups of exemplary weights can be applied, of which each is serviced by a pair of ring beams. Pallets for each group of weights are mounted on a common cargo bar passing through all the weights.
