The current power lifting equipment of the climbing frame is mainly electric hoist lifting, hydraulic lifting, reducer lengthened screw lifting. Climbing frame, the form of external protective frame, is unique and exclusive to China, and can be lifted and lifted in accordance with the requirements of the specifications when the external wall is decorated. The electric hoist used in the climbing frame project is the DHP climbing frame electric hoist. The three basic forms of the climbing frame electric hoist used in the climbing frame project are as follows: 1. The climbing frame electric hoist is hung on the frame body: The climbing frame electric hoist is hung on Inside the frame body, a pulley and a long enough steel wire rope need to be installed at the bottom of the frame body, and the strength of the hanging point of the frame body needs to be increased. Because this method forms a single row of force on the frame body, it is easy to cause deformation of the frame rail. The steel wire rope pulls the lifting frame body, and the steel wire rope and the pulley constantly rub and bend. It is necessary for the staff of the electric hoist climbing frame to constantly check the status of the steel wire rope, which adds labor and instability.
Second, the climbing frame electric hoist is hanging: this situation requires the use of a climbing frame hoist. This state of using the climbing frame electric hoist requires the frame body to move the climbing frame electric hoist one floor high after each lift, and To extend the chain, it requires three or more workers to work together at the same time, each of which takes 15 minutes for smoothness, and the labor intensity of the workers increases. At the same time, because the load control system used is a tension sensor, it is easy to move the electric hoist during the climbing frame. Damage the signal wire of the tension sensor. 3. Electric hoist for climbing frame upside down : In this case, an electric hoist for climbing frame needs to be used. The electric chain hoist of the climbing frame must increase the length of the chain, and it must also have a mechanism to adjust the tension of the chain. After the chain of the electric chain hoist is tensioned, it is necessary to ensure that the three hanging points of the upper, lower and supporting walls are in a straight line. In the course of use, once dirt enters the sprocket and chain joint, it will cause the phenomenon of stuck chains and bite chains, causing the chain to break, resulting in hidden safety hazards.
