(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ НАПРЯЖЕНИЙ БУРИЛЬНОЙ ТРУБЫ(54) DEVICE FOR MEASUREMENT OF DRILL PIPE STRESS

1one

Изобретение касаетс  средств контрол  напр жений , испытываемых бурильной трубой.The invention relates to means for controlling the stresses experienced by the drill pipe.

Р1звестно устройство дл  измерени  напр жений , испытываемых бурильной трубой, содержащее корпус и чувствительный элемент, соединенный с бурильной трубой.A device for measuring the stresses being tested by the drill pipe is known, comprising a housing and a sensing element connected to the drill pipe.

Описываемое устройство позвол ет повысить точность измерени  и надежность работы .The described device allows for improved measurement accuracy and reliability.

Дл  этого оно снабжено защитной втулкой, св занной с чувствительным элементом с помощью соединительного элемента, установленного с зазором. Соединительный элемент выполнен в виде шпонки или резьбы квадратного сечени .For this, it is provided with a protective sleeve associated with the sensing element by means of a connecting element mounted with a gap. The connecting element is designed as a key or square thread.

На фиг. 1 изображено описываемое устройство , общий вид (соединительный элемент выполнен в виде шпонки); на фиг. 2 - то же, соединительный элемент вынолнен в виде резьбы квадратного сечени .FIG. 1 shows the described device, a general view (the connecting element is designed as a key); in fig. 2 - the same, the connecting element is made in the form of a thread of square section.

Устройство содержит корпус 1, чувствительный элемент 2, выполненный в виде муфт и соединенный с бурильной трубой 3, защитную втулку 4, соединенную с чувствительным элементом 2 соединительным элементом, вьшолненным в виде шпонок 5, 6 и 7. Диаметр шпоночного отверсти  8 в чувствительном элементе 2 больше диаметра шпонки и разность между этими диаметрами определ ет величину деформации чувствительного элемента.The device includes a housing 1, a sensing element 2, made in the form of couplings and connected to the drill pipe 3, a protective sleeve 4 connected to the sensitive element 2 by a connecting element made in the form of pins 5, 6 and 7. The diameter of the key hole 8 in the sensitive element 2 larger key diameter and the difference between these diameters determines the amount of deformation of the sensitive element.

Чувствительный элемент 2 под действием напр жений, испытываемых бурильной трубой , деформируетс  и, достига  определенной предельно заданной величины деформации, передает часть усилий через соединительный элемент на защитную втулку 4. В случае разрыва чувствительного элемента защитна  втулка полностью воспринимает на себ  все усили .The sensing element 2 under the action of the stresses experienced by the drill pipe is deformed and, reaching a certain extremely predetermined amount of deformation, transfers part of the force through the connecting element to the protective sleeve 4. In the event of a rupture of the sensitive element, the protective sleeve completely takes all the effort.

На фиг. 2 изображен соединительный элемент , выполненный в виде резьбы 9 квадратного сечени .FIG. 2 shows a connecting element made in the form of a thread 9 of square section.
