(54) DEVICE FOR WEIGHING

one

The device relates to weighing technology, etc. | It is intended to determine the mass of liquid and solid cargoes both on ships and in stationary conditions.

Scales for weighing on ships are known, containing two quadrants, a load receptor and a cam-belt mechanism fl3.

However, these scales do not provide high precision weighing.

The closest in technical essence to the invention is a device for weighing, which contains a system of levers with a load-carrying bowl mounted on it, a weight and damper control HFcjM and a display unit with switches 121.

However, this device also does not provide high precision weighing on ships and is unsuitable for weighing liquid products, such as canned food before rolling.

The purpose of the invention is to improve the accuracy of weighing in pitching conditions.

The goal is achieved by the fact that the device is equipped with a container with a liquid and installed in it in a vertical position with a gimbal suspension with a cargo compensator.

at the lower end, with the indicated system of levers with a bowl, a control weight and dampers installed at the upper end of the stem.

FIG. 1 shows the device, a general view; in fig. 2 shows a section A-A in FIG.

The weighing device comprises a rod 1 mounted in a support 2,

0 carrying a cargo-receiving bowl 3, a control load 4 and dampers 5, placed in a container b with a liquid, the lower end of the rod 1 being equipped with a roll-up cargo compensator 7, and an inking unit 8. The rod 1 is mounted in the form of a yoke and is rigidly fixed on the movable support 2 (Fig. 2). The movable support 2 is made in the form of a gimbal mounted on a stationary frame 9. The platform 10 and two two-arm levers 11 and 12 parallel to each other are fixed perpendicular to it on the upper arm of the rocker arm. Arm ends leverage

11 and 12 are interconnected on the one hand by a rack 13, on which the load-receiving bowl 3 is fixed, on the other hand, one hundred - on 14, on which the control plate-4 is hung (I’m

0 required mass). In order to avoid vibration of the load-carrying bowl 3 when a weighed load is applied to the nba, padlocks 5 are mounted on the platform 10, the rods of which are attached to the lever 12. turning relative to the stand 13, which allows to reduce the dimensions of the device, as well as to turn the bowl in the right direction depending on the desired location of the bowl in the line. To determine the deviation of the weighed cargo from the control one, a magnetic arrow 16 is mounted on the lever 12, and non-contact switches 17 are attached to the platform 10 3s1, to which a shield with electric lamps of the display unit 8 is connected.

The device works as follows.

A weighing load, for example, a filled can, is placed on the cargo receiving bowl 3, a control load 4 is hung on the load 14. The cargo receiving bowl 3 is lowered or raised, depending on the size of the weighed cargo, in a strictly horizontal position regardless of the roll of the vessel, as it is fixed through the rack 13 and the levers 11 and 12 on the rod 1. Magnetic arrow 16 also lowers or rises, closing the lower or upper proximity switch 8, the light bulb lights up

or little. If the arrow 16 is between the upper and lower switches 8, the distance between which is calculated for the upper and lower permissible limits of the weighed cargo lights up; light bulb with the inscription Norma.

The device provides weighing of liquid and solid materials under sea conditions with great precision.
