Driving anti-falling device for lifting of building climbing frame and lifting system of driving anti-falling device

Abstract

The invention relates to a driving anti-falling device for lifting of a building climbing frame and a lifting system.The driving anti-falling device comprises a rack, a climbing device and an anti-falling assembly, the rack is vertically installed on a wall, the outer side of the climbing device is connected with the building climbing frame, and the inner side of the climbing device is meshed with the rack and moves up and down along the rack; the anti-falling assembly comprises a limiting stop block, an anti-falling block, a first gear and a second gear, the anti-falling block is installed on the climbing device through a first pin shaft and can rotate around the first pin shaft, the first gear and the second gear are installed on the climbing device through a second pin shaft, the first gear is meshed with the rack, the second gear is located at the lower end of the anti-falling block, and the limiting stop block is located between the second gear and the anti-falling block. The anti-falling block is provided with anti-falling teeth matched with the second gear, and the anti-falling teeth incline in the direction away from the first pin shaft. When the building climbing frame falls, the anti-falling teeth are clamped on the second gear, the second gear stops rotating, the first gear coaxial with the second gear is clamped on the rack, the climbing frame stops falling, and the safety requirement for falling of the building climbing frame is met.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a driving anti-falling device for lifting and lowering a building climbing frame and a lifting system thereof. Background technique [0002] The climbing frame is a scaffold that can be lifted as a whole. After the climbing frame is built, it can rise or fall along the building as a whole. It has the advantages of less investment, convenient use and strong practicability. Therefore, it is favored by the construction of high-rise buildings. It is the construction process. commonly used construction equipment. In the prior art, one end of the electric hoist is generally fixed on the building, the other end is connected to the climbing frame through a chain, and the whole climbing frame is raised or lowered through the forward or reverse rotation of the electric hoist. Due to the unbalanced weight of the load or when the load exceeds the load of the electric hoist, th...

Problems solved by technology

Due to the unbalanced load weight or when the load exceeds the load of the electric hoist, it is easy to cause a safety accident that the climbing frame falls

In order to avoid the falling failure of the climbing frame, it is necessary to install an anti-falling device on the climbing frame. The existing anti-falling device has a complex structure and a slow response speed. The slippage when the climbing frame falls is generally 120mm-150mm, which cannot meet the requirements of the climbing frame. The safety requirement that the sliding distance of falling should not be greater than 80mm, therefore, an anti-falling device with simple structure and small falling sliding distance of the climbing frame is needed
