Description

one

The invention relates to the field of load measuring technology and can be used to measure the axial pressure of layers of multilayer winding of a rope, cable, etc., on the drum lobovina.

The known devices for measuring the pressure force of the rope on the drum head, made on the basis of strain gauge O (B, glued on the outside of the head, or mesdoses installed in the body of the head 1, 2, do not provide the required accuracy of measuring the axial pressure of the layers of wire winding on the head of the drum.

The closest in technical essence is a device comprising a case with resilient elements arranged in it, made in the form of cantilever beams with strain gages of equal resistance and installed in a polygonal case at right angles to each other, lids-plates and load-receiving contacts mounted on elastic elements, the contact surface of which is flush with the outer surface of the lids 3. However, it also does not provide the required accuracy of measuring the axial pressure of the layers wound n rope on lobovinu drum.

To increase the accuracy of measuring the axial pressure of each layer (winding and revealing the law of distribution of axial pressure

on the front side of all wound rope layers, in the proposed device, containing elastic elements, the contacting surface of which is flush with the front surface, and gauges, the elastic elements are made in the form of elastic fluid-filled reservoirs with sets of splinter-balls, which are installed in the front frame's grooves n connected with gauges.

FIG. 1 shows the described device; in fig. 2 - the same, section along A-A in FIG. one; in fig. 3 and 4 - od, ma insert. The device contains a lobovina 1 with slots 2, in which elastic elements are installed, made in the form of filled l: liquid 3 elastic reservoirs 4 with sets of beams 5, which form flush with the surface of lobovina 1 elastic bands on its wall perceiving axial loads, and gauges 6 associated with the spring-loaded tanks 4.

The device works as follows. On the extreme turn of the layer (not shown), the latter presses on the lobovina 1 and part of the insert on the bulkhead inserts 5. The liners, like the beams on two supports, bend and compress the elastic reservoirs 4, the volume of the tanks is smaller, and the level

fluid 3 in meter 6 is increased. By changing the level of measure 6, the pressure of the winding layer on the lobovi 1 is determined, and only those inserts that are affected by the extreme turn are flexed, and the curvature does not bend on the magnitude of the inserts. Naviva alternate layers, measuring fluid levels, find the pressure of each layer of fluid on the head. The invention of the device for measuring the pressure force of the layers of winding of a rope on a lobovia drum containing its elastic elements, contacting the surface of which is flush with the surface (lobina surface, and gauges, in order to improve the accuracy of measuring axial pressure with each layer of the law of distribution of axial pressures: on the front of all wound layers, in it elastic elements are made in the form of elastic tanks filled with liquid with sets of liners-beams installed in Azov loboviny and associated with gauges.
