Description

Cable support on marine low temperature liquid cargo storage tank Technical Field The utility model relates to a cable bracket on a marine low-temperature liquid cargo storage tank. Background The surface of the low-temperature liquid cargo storage tank on the liquid cargo (LPG, LNG, CO 2) transport ship can be coated with an insulating layer for isolating the external normal temperature state so as to ensure the constant state of the low temperature inside the tank body. The heat-insulating layer of the liquid cargo storage tank is generally provided with an internal heat-insulating foam spraying layer and a heat-insulating hardening layer on the surface. At this time, it is necessary to install temperature sensors at a plurality of positions on the outer surface of the tank for monitoring the actual state of the liquid cargo in the tank. How to lay the sensor cable on the surface of the tank through the cable support is one of the problems to be solved. The cable support comprises at least two support foundations arranged at intervals and a laying channel which is arranged between the two support foundations through two screws, and cables are laid on the laying channel. The support foundation in the current cable support is embedded in the heat-insulating hardening layer on the surface of the tank body, the support foundation consists of an upper disc, a lower disc and round steel coaxially connected between the upper disc and the lower disc, the diameter of the lower disc is larger than that of the upper disc, and the lower disc is embedded in the insulating hardening layer, so that the purpose of stabilizing the support foundation on the surface of the tank body is achieved. The upper disc and the lower disc of the support bottom need iron plate nesting, are welded with round steel into a whole after cutting, are provided with internal threaded holes in the centers of the upper disc and the lower disc and the center of the round steel, have complex whole structure processing, contain round steel and steel plate materials, need finish machining processes such as cutting steel plates, turning internal threads and the like in sequence, have overhigh cost, and have limited quantity of cables (supporting plates) which can be born. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a cable laying device on a marine low-temperature liquid cargo storage tank, which can improve the stability of a cable bracket on an insulating layer of the storage tank, simplify the manufacturing and processing modes and reduce the cost.
