Description

Technical Field

[0001] The utility model relates to the field of steel cage pouring, in particular to a lifting height control device for underwater pouring of steel cages. Background Art

[0002] For underwater apron steel cage pouring, the steel cage needs to be lowered first. When hoisting and placing the steel cage, a truck crane is usually used. However, the existing use of a truck crane brings many inconveniences. The truck crane needs to maintain a safe use distance of 15 m from the wharf front. The time span from leveling the underwater apron steel cage to pouring is several days. The truck crane occupies the land lane behind the wharf, affecting the riding experience of passengers crossing the sea by car and the operation order of the wharf. The seabed topography fluctuates, and the elevation of the wharf front is scoured by the wake of the ship and is also uneven. In order to ensure the elevation accuracy of the underwater reinforced concrete apron pouring, the elevation of the steel cage lowering needs to be controlled. Using a truck crane to control the lowering height by divers going underwater is time-consuming and laborious, and it is difficult to meet the elevation control requirements by using a truck crane and divers. Therefore, we propose a lifting height control device for underwater pouring of steel cages to solve the above problems. Content of the Utility Model

[0003] The utility model provides a lifting height control device for underwater pouring of steel cages, which solves the problems that a truck crane is usually required for the hoisting and placing operation of the steel cage, the truck crane occupies the land lane behind the wharf, affecting the riding experience of passengers crossing the sea by car and the operation order of the wharf, and at the same time, it is difficult to meet the elevation control requirements by using a truck crane, which is time-consuming and laborious.
