SU390232A1 - FAILURE, MOUNTED ON THE WAILER UNIT - Google Patents

Description

one

The invention retracts to the electrical measuring instrument, which is useful in the field of control.

Known casters, which are motivated on a pile-driving unit, are made with a registered unit. Odlax these failure measures do not provide sufficient accuracy.

In order to improve the measurement accuracy, the proposed failure of the measures is made with a displacement-number converter of pulses in the form of a comb strip mounted on the guide boom of a pile-driving unit, interacting with a movable contact mounted on the left-movable part of the hammer and controlled by pulses A counting count and is connected to the recording digitizer.

FIG. 1 shows a block diagram of the proposed refusal; in fig. 2 - transducer displacement-number of pulses; in fig. 3 shows the placement of the converter on the pile-driving unit.

The fault meter consists of a transducer transducer-the number of pulses / performed by p. the form of a fixed co-tact 2 with a comb strip made of hcc-iodic material attached to the guide boom of the pile-driving unit and connected to the power ground, at the contact contact 3, attached to the ijenod Bijio part 4 of the hammer, and guides 5; the driver 6 pulses, the counter 7. yugpulsoz, the control unit 8 and the register diffractor unit 9.

Failure. Measure works as follows.

When the pile is immersed, the movable contact of the converter slides along the protrusions “the single contact of the first contact. The pulses of the measured sequence (the number of pulses per proportional to the amount of movement of the pile) from the output of the transducer through the shaper 6 arrive at the input of the counter 7, which integrates the input pulses for a period of ten frequency / V periods. -facTOTa is the frequency of the hammer or the frequency of impacts. Consequently, impulses are sent to the input of block 8Pravlen.ch, each of which corresponds to one working stroke of the hammer. These impulses can be formed, for example, with the help of a steam distribution device in vapor-air hammers and by adding additional devices in diesel hammers. Counter K counts the number of pulses received at its input during the execution of ten working strokes of the hammer, i.e. during the execution of ten strokes. Consequently, the ravlepi block should contain a divisor by ten, the signal from the output of which will often form in the formation of print and reset pulses. Printing and dumping are carried out until the end of the next bail in ten hammer blows until the next blow is taken. Moreover, the printing of the information on the paper tape of the device 9 is first performed in the counter, and then the counter is set to its initial state, i.e., it is prepared for the next measurement. The accuracy of the measurement is directly proportional to the pitch h of the location of the protrusions on the comb strip. If to use the accepted designations; / e-pulse sequence at the output of the converter; y is the frequency of hammer strikes, the number of pulses N, which is fed to the counter input during the execution of ten strikes, can be determined by formula No. 10 can be a certain deterministic failure by the formula The invention Failure meter, mounted on an aggregate, including A recording unit, characterized in that, in order to improve accuracy, it yen out with a displacement transducer-the number of impulses in the ground fixed on the guide boom of the pile-driving aggregate of a comb-plate interacting with the moving part of the hammer with a movable contact, connected with the pulse shaper, which through a controlled counter is connected to the registering digital printing unit.
