[0082] 3. Install anchor plate

[0083] The anchor plate is anchored with bolts. When anchoring, ensure that the anchor plate and the wall, the bolt gasket and the steel anchor plate must be tightly pressed together without leaving any gaps. Ensure that after tightening the bolts, the gasket can evenly transfer the load to the anchor plate, and the anchor plate evenly transfers the load to the shear wall.

[0084] 4. Install the upper power structure

[0085] According to the design requirements, the upper structure design is mainly that this equipment is the lifting part installed in the elevator shaft, using a 2T electric hoist as the power device, tracks are set on both sides of the inner wall of the elevator shaft, the top longitudinal beam is made of 16# I-steel, and the ends of the two longitudinal beams are anchored on the reinforced concrete shear wall, on which a steel cross beam is set, and the cross section is also 16# I-steel.

[0086] 5. Install the lower loading device

[0087] The lifting part of this equipment adopts lattice beams composed of square steel pipes, which are welded to steel anchor plates on the surface. Channel steels are welded on both sides of the bottom support plate as vertical supports, and the top is welded with channel steels as the lifting and hoisting parts. At the same time, two metal wheels are set on both sides of the bottom support plate, and the metal wheels are placed in the track to avoid large displacement during the operation of the equipment. At the same time, protective fences are set around the support plate, and outward-opening protective doors are set on each layer. During the operation of the equipment, personnel are not allowed to approach, let alone carry people.

[0088] 6. Test run equipment

[0089] After the upper and lower structures of the equipment are installed, test run the equipment to observe whether the equipment travel limit is working normally. The total weight of the hoisted materials is controlled below 600kg. Post a notice board, prohibiting people from getting on the equipment during operation, and set inward-opening protective doors between floors to ensure that the inter-layer protection of the elevator shaft meets the requirements when the equipment is not in operation.
