Abstract

The invention relates to the technical field of expansion joint detection devices, in particular to an expansion joint tensile test device which comprises a mounting base. An expansion joint is arranged at the upper end of the mounting base, pipe openings are fixedly connected to the left end and the right end of the expansion joint, and frame bodies are fixedly connected to the left end and the right end of the mounting base. A mounting plate is fixedly connected between the two frame bodies, a slotted hole is dug in the upper end of the mounting plate, elastic pieces are fixedly connected tothe inner walls of the ends, close to each other, of the two frame bodies, rectangular plates are fixedly connected to the ends, close to the expansion joint, of the elastic pieces, and clamping plates are fixedly connected to the rectangular plates. The clamping plates are matched with the pipe openings in shape, side rods are hinged to the upper ends of the rectangular plates through second hinges, the two side rods are rotationally connected through first hinges, sliding rods are fixedly connected to the upper ends of the first hinges, and the sliding rods are connected with the slotted holes in a sliding mode.

Description

Technical field[0001]The invention relates to the technical field of expansion joint detection devices, in particular to an expansion joint tensile test device.Background technique[0002]Introduction: Expansion joint refers to a flexible element that can effectively compensate for axial deformation. It is composed of bellows (a kind of elastic element) and accessories such as end pipes, brackets, flanges, and conduits that constitute the main body of the work. It belongs to a kind of compensation element. For example, the expansion joint welded to the shell of the fixed tube-plate heat exchanger has large axial flexibility and is easy to deform. It can compensate for the difference in thermal expansion between the tube and the shell due to the difference in wall temperature and reduce their axial Load, thereby reducing the temperature difference stress of the tube, tube sheet and shell, avoiding strength damage, instability damage and tube pull-off damage. There are many types of exp...
