Generally speaking, electric climbing frame technology is widely used in current building construction technology. Its characteristic is to use climbing frame electric hoist as the lifting machine equipment, so that the steel pipe scaffold can climb up along the building wall or column as a whole. It should be noted here that the climbing frame electric hoist is a key process in the overall climbing frame lifting procedure. Next, let's talk about the explanation of the five implementation schemes.
Implementation plan 1: Check whether the electric hoist is safe and whether the lifting beam is installed firmly. When starting the climbing frame electric hoist, tighten the transmission chain to check the hoist, so that the hoist is at the same height and is under normal force and is ready for operation.
Implementation plan 2: Observe the live load and sufficient load on the support after the template is removed. Loosen the fixed tie point between the formwork support and the building. Loosen the bolts and diagonal support rods connecting the bearing support to the building, and observe the stability of the iron frame. Check whether there is any collision or release between the climbing frame and the building. At this time, the climbing frame is only connected or touched with the building by the electric hoist, guide rod, guide wheel and raising steel beam.
Implementation plan 3: When working, the overall climbing frame staff should perform their duties, and the commander-in-chief sends out the raising instruction, and the management control room starts the electric hoist to raise the overall outer frame at a rate of 100mm/min. Pay attention to the elevation of the steel pipe scaffolding. When there is a skew or the elevation of each hoist drive chain is different, a signal will be sent to terminate the hoist, and some hoists of different hoists will be jog solution, and the same level will be maintained before continuing to increase simultaneously.
Implementation scheme four: when the overall climbing frame is raised in place, the bearing support rods and the bearing support are reliably fixed to the building embedded parts or the wall support rods, and at the same time, the outer frame and the building are connected with steel pipe fasteners. The support and tie are firm, and the guide member moves up a layer of ice and is fixed accordingly.
Implementation scheme five: After the overall climbing frame is in place, check the position and support condition of each established support rod separately, and the guides are fixed and stable. Release the pressure on the climbing frame electric hoist, and use the emergency bracelet hoist to lift the heavy machinery and equipment to the upper layer and fix it in place, waiting for the next lift. Normally, the drive chain of the electric hoist is slack.
