Device for fastening a flexible tread elongated articles on a column of tubing in the region of the coupling connecting the column pipe

摘要

The invention relates to drilling equipment. The technical result is to increase the area of ​​abutment of the body casing to the pipe surface, which increases the reliability of fixing of the flexible elongated articles on a column of tubing in the region of their union joint; a deletion at the notch under the clutch housing while retaining the ability to bypass the housing of the coupling, which simplifies the device fabrication technology and its application; in enhancing the bond strength of metal strips the locking elements from the device housing. The apparatus comprises a housing 1 and connected with the housing locking members 2, 3 designed to secure the device on the pipes in the coupling region. The housing 1 is made of a lengthy rigid metal structure formed by forming the conjugated five cylinders 4, 5, 6, 7, 8. All the cylinders of the housing 1 have the same guides, each of which represents a figure including arc 13 and with the ends of two conjugate 14 and 15 of the arc segment 16 and 17. In this case, each segment 16 and 17 is arranged so that it forms an external obtuse angle with the notional straight segment 18, which is a chord of the arc 13. 1 bp f-ly; 6 yl.
