Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The invention is used for testing the sealing performance of the sealing member with various deviations such as axis deviation and uneven compression during installation.

[0016] see figure 1 and figure 2 The structure diagram of the present invention shows that the shield butt joint sealing performance test device includes a front base 1, a plurality of frame beams 2, a plurality of pull rods 12, a rear base 11, a pressure chamber assembly, a top plate 9, a jacking oil cylinder group 10, an eccentric eccentric Angle adjustment screw group 7, attitude locking screw group 13 and load cell 14.

[0017] The front base 1 is a steel plate structure for connecting and fixing other components, and it is connected with the rear base 11 through a frame beam 2 and a tie rod 12, which are arranged around the pressure chamber assembly. In this embodimen...

Abstract

The invention discloses a device for testing abutting and sealing performance of a shield machine. The device comprises a front base, multiple frame beams, multiple pull rods, a rear base, a pressure bin assembly, a top board, a jacking oil cylinder set, an eccentric and deflecting adjusting screw set, a posture locking screw set and a force transducer. The pressure bin assembly is fixed between the front base and the top board, the front base is connected with the rear base through the frame beams and the pull rods. The frame beams and the pull rods are arranged on the periphery of the pressure bin assembly, the posture locking screw set is arranged on the pull rods, and a groove is formed in the top board and connected with the posture locking screw set. The eccentric and deflecting adjusting screw set is fixed on the frame beams and abuts against the pressure bin assembly, and the jacking oil cylinder set is fixed on the rear base and abuts against the top board. The force transducer is arranged on the pull rods between the posture locking screw set and the top board in a sleeved mode. The device can simulate states of axis excursion and uneven compression of a sealing ring in practical application, tests of sealing performance under various conditions are finished, and therefore use reliability of the sealing ring in a special working environment is improved.

Description

technical field [0001] The invention relates to a large-diameter sealing ring performance test device, in particular to a shield butt joint sealing performance test device with adjustable compaction amount and compaction angle. Background technique [0002] In some special working environments, such as in the process of docking equipment underwater, it is necessary to use large-sized sealing rings for equipment docking. In this case, due to the limitation of docking accuracy, it is difficult to ensure concentricity between the two docking devices and Fully perpendicular to the seal. For this reason, it is necessary to conduct a performance test on the sealing ring used before the official construction to ensure its reliability. At home and abroad, there have been many studies on sealing test devices, such as "Sealing Tester" (Chinese Patent No. The sealing test device is mainly used under the condition that the installation accuracy of the rotating parts and the sealing ri...
