Изобретение относитс к весоизмерительной технике, в частности к точным большегрузным весам с автоматическим электросиловым уравновешиванием с нагрузками пор дка 100-1000 кг.The invention relates to a weighing technique, in particular to an accurate heavy load balance with automatic electric power balancing with loads of the order of 100-1000 kg.

Известны большегрузные атоматиче- ские весы, содержащие грузоприемную площадку, подвеску, измерительное коромысло , гиревой механизм, систему уравновешивани , основание и отсчетное устройство 1.Known heavy-duty automatic scales containing a loading platform, a suspension, a measuring beam, a weight-lifting mechanism, a balancing system, a base and a reading device 1.

Известные весы обладают недостаточной нагрузочной способностью, поскольку подвеска с грузоприемной чашкой могут получать перекосы при нецентральном наложении измер емых нагрузок предельной массы.Known scales have insufficient load capacity, since a suspension with a load-receiving cup can get skewed when the measured loads of the maximum mass are off-center.

Известны большегрузные весы, содержащие грузоприемную площадку, измерительную систему в виде пьезоэлектрических месдоз, отсчетное устройство и основаниеKnown heavy scales containing a load pad, a measuring system in the form of piezoelectric pulses, a reading device and a base

Известные весы имеют большую нагрузочную способность, однако их точность недостаточна из-за погрешностей пьезоэлектрических месдоз (утечек зар дов , повышенных давлений в точках контакта с пьезокристаллами и т. д.).Known scales have a large load capacity, however, their accuracy is insufficient due to errors of piezoelectric pulses (charge leaks, high pressures at points of contact with piezoelectric crystals, etc.).

Известные весы при большой нагрузочной способности обладают недостаточной точностью, определ емой предельной точностью последнего измерительного преобразовател типа пьезокристалла (не выше 0,05-0.1 %).Known scales with a large load capacity have insufficient accuracy, determined by the limiting accuracy of the last measuring transducer of the piezocrystal type (not higher than 0.05-0.1%).

Вследствие этого весы не могут использоватьс при точном измерении массы больших навесок, например полудрагоценных и драгоценных металлов, дорогосто щих радиоактивных компонентов и пр., где требуетс повысить результирующую точность до 0,01-0,02 %.As a result, the balance cannot be used to accurately measure the mass of large attachments, such as semi-precious and precious metals, expensive radioactive components, etc., where it is required to increase the resulting accuracy to 0.01-0.02%.

Все это вместе вз тое приводит к снижению достоверности стоимостной оценки сырь и материалов.All this taken together leads to a decrease in the reliability of the valuation of raw materials.

Целью предлагаемых большегрузных автоматических весов вл етс повышение точности измерени массы больших навесок .The aim of the proposed heavy duty automatic scales is to increase the accuracy of measuring the mass of large attachments.

Выходы 19 усилителей 13 электрически подключены через соответствующие катушки 17 компенсаторов 18 к общей точке 19 с суммирующим резистором 20 и с выходом 21 аналого-цифрового преобразовател (от- счетное устройство) 22, а выходы 23 усилителей 13 соединены с общей шиной (корпусом) 24 суммирующего резистора 20 и АЦП 22.The outputs 19 of the amplifiers 13 are electrically connected through the corresponding coils 17 of the compensators 18 to a common point 19 with a summing resistor 20 and with the output 21 of an analog-to-digital converter (counting device) 22, and the outputs 23 of the amplifiers 13 are connected to a common bus (case) 24 of the summing resistor 20 and ADC 22.

Масштабные резисторы 25 служат дл регулировани равенства посто нных компенсаторов 18.Scale resistors 25 serve to control the equality of the constant compensators 18.

Работа весов происходит следующим образом.The work of the scales is as follows.

На грузоприемную площадку 1 устанавливаетс измер емый груз 2 с весом Рх, который распредел етс через подп тники 3 на стойки 4, вызыва соответствующие дополнительные силовые реакции последних RI, причем в равновесном положении сумма всех реакций RI должна быть равна весу Рх груза 2, ZRi Рх, поскольку вес Ро площадки 1 уравновешен гайками 16.A load 2 is installed on the load pad 1 with a weight Рх, which is distributed through the thrust bearings 3 to the posts 4, causing the corresponding additional force reactions of the last RI, and in the equilibrium position the sum of all reactions RI must be equal to the weight Рх of the load 2, ZRi Рх since the weight of Po of platform 1 is balanced by nuts 16.

The purpose of the invention is to increase the reliability of tests by expanding the range of torsion angles by adjusting the neutral vibration with the possibility of stabilizing the neutral in any of the specified positions. The device comprises a control unit consisting of an asynchronous motor 1 with windings 2 and control 3 connected to the i source of alternating current 4 and 5 hours o f; f, respectively, polohenig sensor 5, Signal conditioner 7, revsivnu

The invention relates to testing equipment, namely, devices for testing cable products (cables, wires, cords, ropes, bundles, etc.) for multiple rewinds, and may find application in the electrical industry.

The invention solves the problem of improving the quality of testing cable products.

Devices 1, 2 and 3 are known for testing cable products for repeated bends, consisting of a pulley spirit for bending a product, a tension mechanism. Cyclical rotation of the pulleys is carried out from the engine by means of a kinematic movement pattern.

Device 1 and 2 do not allow double-sided deformation during bending of the article, where sections of the cable article undergo deformation of both compression and tension during one rewind cycle. In addition to tbgo, with such a movement system, the range of the angle of rotation is limited. All of these drawbacks make it impossible to test the products under conditions simulating operating conditions.

A vibratory electric drive is known with stabilization of the amplitude of oscillations of the shaft of the motor 4. However, such a device is an open-loop control system, has no position sensor and, therefore, cannot stabilize the neutral position of the shaft (neutral vibration). In addition, the device is not designed to operate in the range of vibration frequencies characteristic of the testing process of flexible products, i.e., in the area of infra-low frequencies.

A device is also known for controlling a two-phase asynchronous motor in the oscillatory mode of predominantly infra-low frequencies 5. However, such a device is also open in position and does not allow to regulate and stabilize the neutral oscillation.

A device with an electric drive of oscillatory motion is known, comprising a double-winding asynchronous motor, a phase shifter, an alternating current source, a current amplitude regulator, a unit amplitude-variable regulator 16, a master oscillator 17, a switch 18, an actuator for winding the winding of a cable article 19. 3 il.

neutral and a rotation direction sensor connected through the neutral bias unit to the control input of the current amplitude controller, the input of which is connected to the output of the phase shifter, the output to the control winding of the motor 6.

The disadvantages of such a device are, firstly, the low accuracy of speed control, neutral offset

fluctuations due to the lack of information about the position of the rotor at any time, since the feedback sensor present in the device only generates a signal of the direction of rotation of the motor shaft; secondly: the accuracy of stabilizing the neutral oscillation is low for the same reasons. As a result, such a device does not allow to regulate the neutral vibration

the ability to stabilize the neutral in any of the specified positions. This significantly degrades the performance of the drive, causing a versatile movement of the drums,

designed for winding and winding a flexible cable and does not allow the reels to rotate with great accuracy over a wide range of torsion angles.

The closest in technical essence is a device for testing flexible small-sized cables for resistance to multiple rewinds 7, consisting of a control unit kinematically connected to the main drive through gears, where from the rotation motor is transmitted to two black and white gears of the right and left-handed version, which provides the versatile rotation of two axes on which removable reels are worn to wind the cable from one of them to the other under the action of a tensile load.

The disadvantage of such a device is that the presence of electromagnetic relays and starters in the electrical circuit of the control unit reduces the reliability of the installation due to the low resource of these elements. Also reversing

The motor using magnetic starters leads to large dynamic loads at the time of its start-up, which affects the quality of the tests and leads to rapid wear of parts. The inability to stabilize the rotation of the drums during the reversal of the engine does not allow multiple rewinding of cable products in a wide range of torsion angles of the drums.

The aim of the invention is to increase the reliability of tests by expanding the range of torsion angles.

The goal is achieved in that the control unit is made in the form of series-connected signal conditioner, reversible pulse counter, digital storage sampler, digital-to-analog converter, comparator comparison unit, amplitude regulator and master oscillator, position controller, the output of which is connected to the second the input of the comparator, one-shot, the input of which is connected to the control output of the signal conditioner and to the control input of the reversible pulse counter, and the output to the gate input of the digital sampling and storage unit of the switch, the output of which is connected to the input of the preset of the reversible pulse counter, and the input is to the zero potential bus, the rectifier, the input of which is connected to the output of the comparison unit and to the input of the comparator, and the output to the control the input of the amplitude controller, the information input of which is connected to the output of the master oscillator, and the output with the control input of the amplitude controller, the information input of which is connected to the output of the master oscillator, and an output with a control input of the electric motor allowing the input of the amplitude regulator is connected to the input of a single-shot and to the control output of the signal conditioner.

Compared with the closest similar technical solution, the claimed technical solution has the following distinctive features:

the control unit is made in the form of series-connected signal former, reversible pulse counter, digital converter unit, comparator comparison unit, amplitude controller and master oscillator, position controller, the output of which is connected to the second input of the comparison unit, a one-shot, the input of which is connected to the control the output of the signal driver and to the control input of the reversible pulse counter, and the output

- to the gate input of the digital block of sampling and storage of the switch, the output of which is connected to the input of the preliminary installation of the reverse pulse counter, and the input is to the zero potential bus, the rectifier, the input of which is connected to the output of the comparison unit and to the input of the comparator, and the output is with the control input of the amplitude controller, the information input of which is connected to the output of the master oscillator, and the output with the control input of the electric motor, allowing the input of the amplitude controller

5 is connected to the input of a single-shot and to the control output of the signal driver.

Therefore, the claimed technical solution meets the criterion of novelty.

When implementing the invention, an extension of the range of the angle of rotation is achieved by adjusting the neutral vibration with the possibility of stabilization

5 neutral in any of the specified positions. When implementing the invention, the functionality of the device is expanded due to the ability of the device to provide a sample cable product

0 when testing for rewinding on rotating drums, various angles of its twisting, precise and convenient adjustment by stabilizing and adjusting the neutral vibration of the actuating motor

5 in any of the given positions.

Compared with the effect of the prototype, a new effect is obtained due to the fact that the control unit of the device is made in the form of a signal shaper that processes the signals of a position sensor located on the motor shaft and generates pulses of a given duration for a reversible counter of forward and reverse pulses
