Pulley type positive hanging hoist installing structure for climbing frame lifting

Abstract

The invention discloses a pulley type positive hanging hoist installing structure for climbing frame lifting. An upper hoisting point is installed at a high position of a climbing frame, and a positive hanging hoist and an upper chain wheel are installed on the upper hoisting point; a middle hoisting point is installed at a middle position of the climbing frame, and the middle hoisting point is fixed to a building wall; a hoisting wheel is further arranged at the middle position of the climbing frame in a suspended mode, and the upper part of the hoisting wheel is provided with an upper supporting point; the lower part of the hoisting wheel is provided with a lower supporting point; a lower hoisting point is installed at a lower position of the climbing frame, and a pulley is installed onthe lower hoisting point in a pivot-joint mode; and one end of a chain is fixed to the upper supporting point of the hoisting wheel, after the upper chain wheel is passed through upwards firstly, thehoisting wheel is passed through downwards, and finally, the other end of the chain passes through the positive hanging hoist; one end of a steel wire rope is fixed to the lower supporting point of the hoisting wheel, and the steel wire rope passes through the pulley; and the other end of the steel wire rope is fixed to the middle hoisting point. According to the pulley type positive hanging hoistinstalling structure for the climbing frame lifting, the structure is simple, the installing cost is low, the lifting operation and the lowering operation of the climbing frame are smooth, the reliability is improved, and the potential safety hazards are eliminated.

Description

technical field [0001] The invention belongs to the technical field of climbing frame lifting systems, and in particular relates to a pulley-type hanging hoist installation structure for climbing frame lifting. Background technique [0002] The climbing frame, also called the lifting frame, is a new type of scaffolding system developed in recent years, mainly used in high-rise shear wall buildings. It can climb up or down the building. This system completely changes the scaffolding technology: first, there is no need to turn over the shelf; second, it eliminates the disassembly and assembly process of the scaffold (it is used after one assembly until the construction is completed), and it is not limited by the height of the building, which greatly saves manpower. and materials. And from the perspective of safety, it has greatly improved the traditional scaffolding. It has great development advantages in high-rise buildings. [0003] The climbing frame hoist is a kind of ...

Problems solved by technology

[0004] In the prior art, the hoist used for lifting the climbing frame is generally installed upside down. When it is installed on the construction site, the cement, mortar, and dust are flying on the construction site. During operation and use, there must be a special person responsible for irregular cleaning and maintenance. However, even so, there are still premature damages to the upside-down hoist, and the reliability of the system performance is poor, which affects the construction work.

[0005] Later, some operators developed the installation method of front hanging hoist. However, chains are used, and the guide wheels matched with the chains are all sprockets. It is easy to accumulate dust, especially if there is too much dust between the chain and the sprocket at the hanging point, the friction will increase, the energy consumption will increase, the operation will not be smooth, the reliability will be reduced, and there will be safety hazards
