Abstract

The invention relates to a slip based on improvement in the alignment effect. The slip comprises a first slip part and a second slip part, wherein first fixing blocks are arranged on the first slip part, second fixing blocks are arranged on the second slip part, the first fixing blocks and the second fixing blocks are provided with through holes for threaded rods to pass through, the first slip part and the second slip part form the fastening slip through matching between the threaded rods and nuts, a through groove is formed in the side wall of each first fixing block, a fixing rod is arranged at the bottom of each through groove, two fixing pieces are arranged on each fixing rod, a connecting plate is arranged between the two fixing pieces on each fixing rod, a through hole is formed in each connecting plate, two connecting rods are hinged to the lower end of each connecting plate, a clamping plate is arranged between the movable ends of every two corresponding connecting rods, a spring is arranged between every two corresponding connecting rods, a groove is formed in each second fixing block, and a clamping groove matched with the corresponding clamping plate is formed in the side wall of the corresponding groove. The slip solves the problem that an existing slip is prone to inaccurate alignment in the matching process of the first slip part and the second slip part.

Description

technical field [0001] The invention relates to the field of auxiliary devices for petroleum pipelines, in particular to a slip based on improving the alignment effect. Background technique [0002] During the transportation of extracted oil, due to the long transportation route, the oil pipelines used for transportation usually use multi-section pipelines for transportation, and multi-section pipelines are connected by multi-section pipelines. In the process of pipeline connection, slips are usually used as the fastening device for pipeline connection. [0003] Slips generally include first slips and second slips forming fastening slips, and the two slips are fixed by bolts. [0004] The existing slips easily lead to inaccurate alignment between the first slip and the second slip during the mating process. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a slip based on improving the alignment effect, so as to ...
