A miniature trolley used for installation and inspection of asphalt cargo tank adjustment pads

Abstract

The invention relates to the technical field of installation inspection of asphalt ship cargo tanks, and discloses a mini vehicle for inspecting installation of adjusting pads of asphalt ship cargo tanks. The mini vehicle includes a vehicle body. At that upper part of the vehicle body, a general gauge and a floating stop gauge are arranged. The top height of the general gauge is equal to the minimum value of the height between the bottom plane of the cargo tank and the adjusting pad before the cargo tank falls. The floating stop gauge comprises an upright lifting lever, the lifting lever is lifted upward by a spring, the upper end of the lifting lever is provided with a roller, and the lifting lever is connected with a first metal contact piece. An upper part of that vehicle body is provided with an insulating block. A second metal contact piece is arranged on the insulating block. When the first metal contact piece and the second metal contact piece just contact, the height of the uppermost end of the roller wheel is equal to the maximum value of the height between the bottom plane of the cargo tank and the adjusting pad before the cargo tank falls. The rear part of the vehicle body is connected with a handle through a hinge shaft, and the handle is provided with a battery and a signal lamp. The mini vehicle can improve detection efficiency and has good convenience.

Description

technical field [0001] The invention relates to the technical field of installation inspection of asphalt cargo tanks, in particular to a miniature trolley used for installation inspection of asphalt cargo tank adjustment pads. Background technique [0002] The cargo tank support in a large asphalt ship is an effective carrier for the cargo tank to bear the load and reduce the structural deformation caused by heat transfer. The effective contact surface between the steel adjustment block in the tank support and the cargo tank is an important part that affects the load bearing of the liquid cargo tank (the contact of all the tank pads must be greater than 70%, and the contact area of ​​each block needs to be more than 35%) . According to the installation process requirements of the cargo tank of the asphalt ship, the installation of the cargo tank adjustment block is completed. When the ship is not loaded, adjust the steel pad and the fixed steel pad at the bottom of the car...

AI Technical Summary

Problems solved by technology

[0006] Since the installation of cargo tanks of large asphalt ships needs to be submitted to the shipowner for inspection in important installation links (after the installation of the adjustment pads and before the cargo tanks are placed), if the inspection is submitted to the shipowner, manual measurement and verification by craftsmen is still required. It not only wastes the valuable time of the shipowner, but also affects the installation cycle of the cargo tank, which in turn affects the progress of a series of cargo tank piping systems, oil stringing, etc.
