(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ДЛИНЫ ПЕРИМЕТРА ОБЪЕКТА(54) DEVICE FOR MEASURING THE LENGTH OF THE OBJECT PERIMETER

1one

Устройство относитс к области технических измерений, а именно к опреде-пению длины периметра в поперечном сечении различных объектов.The device relates to the field of technical measurements, namely, to determine the length of the perimeter in the cross section of various objects.

Известно устройство дл измерени I длины периметра объекта, содержащееA device for measuring the perimeter length I of an object is known, comprising

основание, гибкий нераст жимый элемент, образующий петлю и установленный на основании с возможностью изменени дгашы петли привод изменени дгашы гибкого элемента, выполненный в виде барабана , установленного на основании, и отсчетный узел.a base, a flexible non-expandable element forming a loop and mounted on the base with the possibility of changing the loop loop drive, a change in the arc of the flexible member, made in the form of a drum mounted on the base, and a reading unit.

Недостатком известного устройства вл еас сложность проведени замеров ,5 в воде при наличии течений иэ-за потери гибким элементом формы петли.A disadvantage of the known device is the difficulty of measuring, 5 in water in the presence of currents, due to the loss of a flexible element in the form of a loop.

Цель изобретени - удобство проведени замеров в воде.The purpose of the invention is the convenience of measuring in water.

Указа1ша цель достигаетс тем,20The goal is achieved by the fact 20

что оно. снабжено установленными на основашш с возк{ожногтью перемещени вдоль него и фиксации в крайних положени х каретками-кольцами, через которые пропущен гибкий элемент, и грузами , установленными на элементе с возможностью перемещени вдоль него и фиксации в требуемом положении.what is it. equipped with a carrier installed on the base with the possibility of moving along it and fixing in extreme positions the carriages-rings through which the flexible element passes, and weights installed on the element with the possibility of moving along it and fixing in the required position.

На фиг. 1 показана конструктивна схема устройства; на фиг. 2 - то же, в процессе измерени .FIG. 1 shows a structural diagram of the device; in fig. 2 is the same in the measurement process.

Устройство содержит основание, выполненное в виде направл ющей штанги 1, состо щей из двух полых труб, шарнирно присоединенных к трубке-ручке 2 с возможностью складывани прт транспортировке каретки-кольца 3, установленные на направл ющей штанге 1 с возможностью перемещени вдоль нее и фиксации в крайних положени х подпружиненными упорами 4. Подпруж1шенные . упоры 4 тросиком 5 св заны с управл ющим рычагом 6, установленным в трубк&-ручке 2.The device comprises a base made in the form of a guide rod 1 consisting of two hollow tubes pivotally attached to the handle tube 2 with the possibility of folding the conveyor ring 3 to be transported, mounted on the guide rod 1 with the possibility of moving along it and fixing it in extreme positions with spring-loaded stops 4. Springs. the stops 4 with a cable 5 are connected to a control lever 6 installed in the tube of & handle 2.

Claims

The device also contains a flexible non-extensible element 7, passed through the carriage-ring 3 and connected to the method of changing its length. In a top-notch view of the drum 8, and the reference node 9, it is possible to determine the flexible element 7, which forms a loop. On the flexible element 7 installed cargo 10, which, if necessary, can be mixed along the latter and fixed in the desired position. The measurement of the perimeter length of the object is as follows. The device in the assembled form is transferred to a timber bundle, the second perimeter must be measured. Directly on the beam, the device is brought to the standby position for measurement, for this purpose the tubes of the guide rod 1 are unfolded from the drum 8, the flexible non-extensible element 7 is completely collapsed, the carriage rings 3 are mixed to the extreme positions on the directions of the rod 1 and fixed there spring-loaded lugs 4. In the presence of loads 1O fixed in the required places on the flexible element 7, the latter takes the form of a rectangular loop, which winds under the beam from the torn to the middle section. Then, when the control rod is operated, the stops 4 are released, and the ring carriages 3 can be freely mixed along the guide rod. Rotating the drum 8, the flexible element 7 is wound on it until the loop is finished with a bundle of timber, after which the readings are taken from the slid knot. The proposed device allows for convenient and quick measurements of the length of the perimeter and of the floating in the water of the timber bundles. The invention The device for measuring the perimeter length of an object, comprising a base, a flexible non-expandable element, forming a loop and mounted on the base with the possibility of changing the loop length, a drive of varying the length of the flexible element, performed in the form of a drum mounted on the base, and a reference node characterized by that, for the purpose of convenience of measurements in water, it is equipped with carriages-rings installed on the base with the possibility of movement along HIM and fixation in extreme positions, through which a flexible element was started up, and with loads mounted on the flexible element with the possibility of moving along it and fixing it in the required position.
