(54) DEVICE FOR THE DAY OF WEIGHING CARGO IN LOADING

TROLLEY

I

The invention relates to the field of v weighing equipment, in particular to devices for weighing vehicles.

 Devices for weighing materials are known, nepeMentaeNbix by foundry loading trolleys, containing a weighing hopper mounted on the chassis of the balance and connected to a force-measuring transducer Co.

A disadvantage of the known devices is the complexity of their design and the difficulty of transmitting the readings of the weight meter.

The closest in technical essence to the present invention is a device for weighing a load in a loading carriage containing a cargo load. receiving tray, hinged on brackets mounted on the ho: common part of a trolley mounted on rails I.

The disadvantage of the device is. The accuracy of measuring the weight of the load is low, due to the placement of the weight-measuring mechanism on the trolley, working. melting in an area with variable temperature gradients and design complexity.

The purpose of the invention is to improve the measurement accuracy and simplify the design.

This goal is achieved by the introduction of guide beams,

10 mounted parallel to the rails, the load receiving tray being provided with wheels, and mounted on the brackets with the possibility of vertical movement, moreover in guide beams

IS mounted tweezers for interacting with the wheels of the load-receiving tray.

30 of FIG. one; nd FIG. 3, 4, 5 and 6, variants of the device; in fig. 7 is a diagram illustrating the operation of the device. The device contains a wheelhouse 1, a load receiving tray 2, which can rotate around axis 3 using a remotely controlled lifting mechanism (not shown), weight sensors 4-7, the number of which may be four or three. They can be made in the form of elastic elements equipped with displacement transducers into an electrical signal, or in the form of transistors, or magnetoelastic transducers, etc. The holes in 8 sleeves 9 of both chassis brackets 10 are elongated. Tray 2 is equipped with olors P, on which wheels 12 are fixed, the number of which may be four or three. Along the base of the rail 13 there are beams guide 14, having bevels 15 along the edges, sensors 4-7 weights are placed in guide beams 14 Wheels 12 can be placed outside of the tray 2, while beams 14 are placed respectively outside main rail track trolley (Fig. H). Wheels 12 and beams 14 can be placed inside the main gauge of those beds (Fig. 4). Two wheels of the tray, for example, rear wheels (Fig. 5) or front wheels (Fig. 6), can be placed outside the main gauge, and the third wheel inside this gauge . The device works as follows. In the initial state, the cart is in position A (Fig. 7), with this wheels I2 of tray 2 resting on weight sensors 4-7 embedded in beams 14. In this position, tray 2 is immersed with charge materials, for example, using bridge grab the crane. After loading, the massatr is determined along with the tray. At the same time, the mass of the trolley part with the engine does not affect the measurement result. After that, the cart is set in motion, with the wheels 12 of the chute 2 moving down along the guide rails 14 and hanging freely in the spirit. In this state, the carriage approaches the position B, in which it is unloaded by lifting tray 2 (Fig. 1) approximately on an axis of about 30-40. At the same time, the load of the tray 2 is poured into the receiver 16. Next, the cart is moved to its original position A, at the approach to which the wheels 12 of the tray 2 enter the respective beams guide 14. The stopping position of the cart is determined by the location of the limit switch (not shown) of the cart engine . Next, tray 2 is loaded with a new load and the process is repeated. The described construction of the device increases reliability due to the prolonged life of the weight sensors placed at a large distance from the furnace. On the other hand, the accuracy of determining the mass of the cargo compared with the platform scales, which the carriage enters, increases, since the mass of the undercarriage of the carriage including the engine does not affect the measurement result. Claims An apparatus for weighing a load in a loading trolley, comprising a load receiving tray, hinged on brackets, mounted on the undercarriage of a trolley mounted on rails, characterized in that, in order to improve the accuracy and simplify the design, beams guide mounted parallel to the rails, with the load receiving tray: provided with wheels, and mounted on the brackets with the possibility of vertical movement, and in the beams, guides mounted sensors; weight to interact with the wheels of the cargo intake tray.
