Bridge cantilever construction hanging basket walking system and operation method

Abstract

The invention discloses a bridge cantilever construction hanging basket walking system and an operation method. The system comprises a hanging basket device, a jacking structure, an oil jack structure and a walking system. The walking system comprises a winch set and a wheel set. The wheel set is integrated on the hanging basket device, and the hanging basket device is driven by the winch set to move in the length direction of the bridge. According to the walking system, the multiple winches serve as power mechanisms, fulcrum and overall movement of the hanging basket device is achieved step by step under the guiding effect of the corresponding fixed pulleys, the structure is novel, the automation degree is high, and construction operation is convenient; a mechanical automation principle is adopted on the whole, the construction efficiency and the construction quality are improved, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of bridge rigid frame cantilever construction, in particular to a walking system and an operation method for a hanging basket device for bridge cantilever construction. Background technique [0002] During the construction operation process of bridge rigid structure (continuous beam) cantilever construction tool-hanging basket, the traditional ones are manual operations. Due to space constraints, it is very inconvenient and unsafe. When the hanging basket is moved forward, the front and rear fulcrum positions must be jacked up one by one, and then the forward movement can be unified; the forward movement is operated by a manual chain hoist, which is time-consuming and laborious, and it can also be pushed by a jack, but the speed is too slow.

Problems solved by technology

[0002] During the construction operation process of bridge rigid structure (continuous beam) cantilever construction tool-hanging basket, the traditional ones are manual operations. Due to space constraints, it is very inconvenient and unsafe

When the hanging basket is moved forward, the front and rear fulcrum positions must be lifted one by one, and then the forward movement can be unified; the forward movement is operated by a manual chain hoist, which is time-consuming and laborious, and it can also be pushed by a jack, but the speed is too slow

Due to the uncertainty of the design and construction of the construction hanging basket, one hanging basket is used for one project, and there is no turnover, resulting in great waste

[0003] At the same time, the movement of the hanging basket device in the prior art mainly adopts manual or jack propulsion, which makes the construction difficult and the accuracy cannot be guaranteed.
