Device for positioning load cells of vertical storage systems

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a device for positioning load sensors of hoppers of vertical bulk material storage systems, which is useful in the field of bulk material storage.

BACKGROUND OF THE INVENTION

Devices are known to be placed on hoppers or on their supports or suspensions for sensing loads of whole vertical bulk material storage systems.

A disadvantage of the above solution is that the device senses the total load of the bulk material storage system. This does not make it possible to determine the load ratio of the hopper and the vertical part of the storage system.

Another disadvantage of the above-mentioned solution is the inability to sense any location of the hopper, which does not allow to determine the location of the maximum load of the hopper.

SUMMARY OF THE INVENTION

These disadvantages are solved by the device for positioning the load cells of the bulk material storage systems of the present invention. The device consists of a stable base frame, at least three extendable supports or at least three extendable hinges, a swivel frame, swivel-mount brackets and hopper load sensors. Advantageously, a hopper wall deformation sensor and / or a displacement sensor of the measuring element and / or a pressure sensor on the hopper wall can be used as a hopper load sensor.

It is an object of the present invention that the stable base frame has the possibility of uniform lifting in the direction of the main vertical axis of the device within the range given by the lifting device of the pull-out supports or pull-out hinges. Preferably, a mechanical, pneumatic or hydraulic element can be used as the lifting device.

SUMMARY OF THE INVENTION The present invention provides a symmetrical location of at least three rotatable load cell holders on a rotatable frame by means of which rotatable load cell holders can be rotated about a major vertical axis of the device by an angle of 0 to 360 degrees to provide load sensing. all selected hopper points, the pivoting frame being supported on a stable base frame.

SUMMARY OF THE INVENTION The object of the present invention is to place at least three rotatable load cell holders on a rotatable frame such that individual displacement of each rotatable load cell holder with a definable distance along the horizontal axis of the rotary slider can be provided for sensing loads of hoppers of different sizes and shapes.

The object of the present invention is to place at least three rotary-sliding holders with load cells on a rotating frame so that each rotary-sliding holder can be individually rotated with a thrust frame.

EXAMPLE Embodiments of the invention

The device for positioning the load hopper load detectors of the vertical bulk material storage systems 1 according to an exemplary embodiment consists of a stable base frame 2, three extendable supports 31, 32, 33 or three extendable hinges 34, 35, 36, rotary frame 4, three rotatable slide holders 51, 52, 53 and hopper load sensors 61, 62, 63. The uniform support stroke of the stable base frame 2 in the direction of the main vertical axis "D" of the device 1 is provided by pull-out supports 31, 32, 33 or pull-out hinges 34, 35, 36 within the range given by the lifting device. Advantageously, a mechanical, pneumatic or hydraulic element may be used as the lifting device. A rotatable frame 4 is mounted on a stable base frame 2, which is allowed to rotate about the main vertical axis "D" of the device 1 by an angle δ within the range of ⁵ ° to 360 °. The rotatable slide holders 51, 52, 53 with hopper load sensors 61, 62, 63 are evenly mounted on the rotary frame 4 so that the rotatable slide holder 51 with load sensor 61 has the ability to rotate about the axis "α" by an angle α of 0. up to 360 °, further the rotary-slide holder 52 with load sensor 62 has the ability to rotate about axis "b" by an angle β in the range 0 to 360 ° and the rotary-slide holder 53 with load sensor 63 has the ability to rotate about axis "c" χ in the range of 0 to 360 °. The rotary slide holders 51, 52, 53 are disposed uniformly on the pivot frame 4 with the hopper load sensors 61, 62, 63 so that they can be individually moved in the direction of the horizontal axis of the rotary slide holders 51, 52, 53.

The device for positioning the load cell load sensors of the vertical bulk material storage systems 1 is positioned below the circular dump 7 or below the rectangular dump 8 so that the load cell load sensors 61, 62, 63 are horizontally and vertically aligned to the sensing points of the circular dump 7 or rectangular dump. Vertical adjustment of the hopper load sensors 61, 62, 63 is carried out by means of extendable supports 31, 32, 33 or retractable hinges 34, 35, 36. Horizontal adjustment of the hopper load sensors 61, 62, 63 is performed by rotatable slide holders 51, 52, 53 depending on the shape and size of the circular hopper 7 or the rectangular hopper 8. Thereafter, the load sensing sequence of the released circular hopper 7 or the rectangular hopper 8 is performed under various operating conditions using the hopper load sensors 61, 62, 63.
