Landing anti-swing system and method for concrete material tank of dam construction cable crane

Abstract

Landing anti-sway system for concrete tank of dam construction cable crane, including feeding positioning mechanism and traction speed regulating mechanism; on the feeding platform of the feeding positioning mechanism, two fixed pulleys are fixed inside the fort and the wheels are parallel to the ground , and install a double-barrel hoist in the horizontal direction of the fixed pulley, the first rope and the fixed pulley together form a four-line track, so that the material tank can move back and forth under the traction of the hoist, and can be positioned accurately and quickly; the traction speed regulating mechanism includes an assembly speed sensor The hook of the cable crane and the upstream cable-stayed positioning hoist connected to the adaptive speed regulator can quickly position the material tank at the dam position to be poured and prevent collision accidents when the material tank of the cable machine enters the warehouse. It greatly improves the time efficiency and safety of the cable crane for lifting heavy objects.

Description

technical field [0001] The invention relates to the field of dam construction, in particular to a landing anti-sway system and method for a concrete material tank of a dam construction cable crane. Background technique [0002] As an important means of vertical and horizontal transportation for dam concrete pouring, the cable crane has the characteristics of one-time construction and full construction period income. Due to the high cost of large mobile cable cranes, small fixed cable cranes are often used in small arch dam projects to save construction costs. However, the small fixed cable crane cannot cover the whole warehouse of the translational cable crane, and cannot locate the hanging tank in the concrete warehouse, so that the concrete pouring cannot be carried out continuously and evenly, and cold construction is easy to occur, which affects the quality and progress of the project. [0003] In addition, the dam is used as the material receiving end. When the cable c...

AI Technical Summary

Problems solved by technology

However, the small fixed cable crane cannot realize the full warehouse coverage of the translational cable crane, and cannot position the hanging tank in the concrete warehouse, so that the concrete pouring cannot be carried out continuously and evenly, and construction cold joints are easily generated, which affects the quality and progress of the project.

[0003] In addition, the dam is used as the material receiving end. When the cable crane encounters strong winds and uneven speed control when lifting the material tank, it is difficult for the cable machine to accurately position the material tank at the fixed position of the dam, and the process of adjusting the material tank is time-consuming. It also prevents the continuous and balanced pouring of concrete, which affects the quality and progress of the project.
