Roll-on roll-off ship fixed ramp type value measuring tool

Abstract

The invention relates to a roll-on roll-off ship fixed ramp type value measuring tool, which is characterized in that a vertical rod is provided with a sliding fixed platform capable of sliding and being locked along the vertical rod, and the sliding fixed platform is connected with one end of a horizontal rod with scales and enables the horizontal rod with the scales to be perpendicular to the vertical rod; a cable pulley assembly capable of sliding along the horizontal rod with the scales and being locked is arranged on the horizontal rod with the scales, a laser range finder is fixedly arranged on the lower portion of the cable pulley assembly, and the emission direction of the laser range finder is parallel to the vertical rod; and a permanent magnet is arranged at the other end of thehorizontal rod with the scales and used for being attracted and fixed to a roll-on roll-off ship fixed ramp. According to the roll-on roll-off ship fixed ramp type value measuring tool, the head andtail end type values of the ramp can be rapidly measured by a single person and are rapidly compared with standard type values, and whether a specified vehicle model is collided when passing through the ramp is effectively pre-judged, so that local maintenance reinforcement suggestions are provided for the fixed ramp which cannot meet the specified vehicle passing requirement, and economic lossesin the vehicle loading and unloading process of a shipholder are avoided.

Description

technical field [0001] The invention relates to an auxiliary measuring device in the maintenance process of a ship, in particular, it is a measuring tool for the type value of a fixed ramp of a roll-on-roll-off ship. Background technique [0002] Car ro-ro ships are a major means of transportation for cars. As the market's demand for cars rises, its manufacturing volume is also increasing. The fixed ramp of the ro-ro ship is a necessary car loading and unloading structure in the ro-ro ship, and its type value is a necessary parameter for the ship owner to ensure the safety of car transportation. The type value is a mathematical expression of the set of points distributed in the three-dimensional space of the product structure in the shipbuilding field, which can clearly reflect the shape of the product in the three-dimensional space. [0003] The type value of the fixed ramp of the ro-ro ship will be made according to the designed type value during the ship production. How...

Problems solved by technology

However, when the ro-ro ship floats on the water surface, there is a trim angle on the horizontal plane, and the general measurement method is difficult to correct the trim of the ship, so the measurement is difficult, and there is no good solution in the existing technology
