A Positionable Scaffold

Abstract

The invention relates to a positionable scaffold, which comprises planks, chains, and positioners; first air tubes are arranged in the planks, both ends of each plank are provided with mounting sockets, and the centers of the mounting sockets are provided with shaft holes; both ends of each chain are fastened in lifting eyes of the neighboring plank; each positioner comprises a positioning sleeve,a positioning pile, and a gear assembly, the positioning sleeves are arranged on the bottoms of both ends of the planks, and the sidewall of the positioning sleeve is provided with a slot; the positioning pile is hollow, the outer wall of the middle portion of the positioning pile is sunk to form a platform, the platform is provided with convex teeth, and the teeth are located in the slot of thepositioning sleeve; the gear assembly comprises a driving gear, a limit ring, and a handwheel, the driving gear, the limit ring and the handwheel are sequentially fixed on the same rotary shaft, the rotary shaft is mounted in the shaft hole of the mounting socket, and the handwheel can be rotated to drive the positioning pile to extend or retract in the positioning sleeve. The scaffold disclosed by the case can be sucked on the side of a ship, and can be effectively prevented from shaking, guaranteeing the safety of high-altitude operation; the first air tubes are arranged inside, the first air tubes, the positioning piles and an exhaust fan are connected through connectors, and thereby the positionable scaffold is more convenient to assemble.

Description

technical field [0001] The invention relates to a scaffold, in particular to a positionable scaffold. Background technique [0002] Traditional vertical scaffolding is often used on construction sites. It is built layer by layer from the ground to provide pedals for workers to work in the air. Traditional vertical scaffolding is usually built with bamboo, steel pipes or synthetic materials. Scaffolds made of steel pipes or synthetic materials Fasteners are usually used for connection, which has strong versatility and is currently the most widely used form of scaffolding. [0003] In the previous domestic shipbuilding industry, most of the above-mentioned traditional vertical scaffolds were used for aerial work, and these steel pipe scaffolds were dismantled after the construction was completed. There are many defects in this method, such as low efficiency, danger, long construction period, and large floor space when steel structure components are stored, which reduces the u...

Problems solved by technology

However, this kind of suspended scaffold for ships also has certain safety hazards, especially when the wind is strong, the springboards connected by cables and chains cannot be fixed, and they shake a lot, which cannot guarantee the safety of aerial workers.
