A loading test bench for clamping components of submarine pipelines

Abstract

The invention provides a loading test stand for a submarine pipeline clamping component. The loading test stand comprises a base, a first hydraulic cylinder, a second hydraulic cylinder, a third hydraulic cylinder, a fourth hydraulic cylinder, a four-bar mechanism and a horizontal force loading pressure plate. A first base guide rail and a second base guide rail are arranged on the two sides of the base respectively, the four-bar mechanism comprises a support, a lower connecting rod, an upper connecting rod and a pressing rod, the support is installed on the base, the lower connecting rod is connected with the upper connecting rod, the upper connecting rod is connected with the pressing rod, the middle of the pressing rod is installed on the support, a sliding guide rail is arranged on the base and provided with a pressure plate movable support, a piston rod of the first hydraulic cylinder is connected with the pressure plate movable support, the horizontal force loading pressure plate is installed on the pressure plate movable support, a piston rod of the second hydraulic cylinder is connected with a rack pull rod, the lower connecting rod is provided with a gear, the rack pull rod is matched with the gear, a pipeline test piece is installed between the base and an upper beam plate, and a piston rod of the third hydraulic cylinder and a piston rod of the fourth hydraulic cylinder are connected with the upper beam plate. The loading test stand is high in precision, compact in structure, easy to operate and large in loading range.

Description

technical field [0001] The invention relates to a test bench, in particular to a test bench for simulating the impact force of ocean currents on a pipeline clamping member. Background technique [0002] The development of offshore oil and gas resources is of great strategic significance to the development of various countries. However, as we all know, the internal environment of the ocean is very different from the land environment. And construction has brought great difficulties. Especially at present, the development of offshore oil and gas resources has gradually moved from shallow sea to deep sea. The influence of waves on the stability of seabed components considered in the previous design is gradually weakening, while ocean currents have become one of the key marine environmental loads to consider. In such a deep-sea environment, the design cost of underwater operation equipment is high and the risk is high. Once a problem occurs, the loss is very serious, and sometim...
