Device and method for installing liquid cargo tank maintenance system module

Abstract

The invention relates to a device and method for installing a liquid cargo tank maintenance system module. The device comprises a spider clamping rod, two short connecting rods, a long connecting rod, a rotating connector installed at one end of the spider clamping rod and a threaded connector installed at the other end of the spider clamping rod. A limiting check ring for limiting during installation of the short connecting rod and the long connecting rod is further arranged at the end, close to the rotating connector, of the spider clamping rod, and the long connecting rod and the short connecting rod are separated through the limiting check ring. The length of the long connecting rod is smaller than that of the short connecting rod. One end of the long connecting rod and one end of the short connecting rod are arranged outside the spider clamping rod in a sleeving mode, and the other end of the long connecting rod and the other end of the short connecting rod are respectively provided with a supporting leg. During use, the threaded connector is connected to a base, and the rotating connector is rotated to enable the supporting legs to tightly press the liquid cargo tank maintenance system module. Compared with the traditional technology, the device is easier to operate, can be quickly mounted by being matched with an electric tool and a pneumatic tool, and has particularly outstanding beneficial effects for a large number of operations.

Description

technical field [0001] The invention relates to the field of installation of insulating layers of liquid cargo tanks, in particular to a device and method for installing modules of a liquid cargo tank maintenance system. Background technique [0002] The ship containment system consists of two layers of insulation and two layers of film. The secondary insulation assembly work is one of the most arduous tasks in the construction of the cargo tank containment system. The whole ship consists of 24,000 secondary level boxes and 23,788 main level boxes, each 4 installers lift the box to the corresponding position, fix it to the liquid cargo bulkhead through spider clips and connecting rods, then adjust the box to the quality control range, and remove the spider clips on the box the next day. Replace the special insulation box connection sleeve. [0003] The prior art, such as the invention patent with the application number CN200710172097.4, discloses a spider clamp and an insul...

Problems solved by technology

[0005] However, each spider leg (support rod and support base) in the existing spider clips and temporary fixing devices needs to be fixed separately, which is cumbersome and inefficient to operate.
