Detailed Description
The utility model will now be described in detail with reference to the drawings and specific examples.
The set of rack consists of a main rack 1 and a small supporting platform 9. The overall size of the main body stage 1 is about 7700mm (length) ×5700mm (width) ×18100mm (height), and the overall size of the small support stage 9 is about 1750mm (length) ×3858mm (width) ×3310mm (height). The main body bench 1 is of a vertical structure and is provided with 4 layers of working platforms 3. Each layer of working platform 3 is connected with the vertical upright posts 4 through high-strength bolts, and the inclined upright posts 2 are additionally arranged between the working platform 3 and each vertical upright post 4 for reinforcement and stabilization. In order to meet the height requirement of the crane, the side surface of each working platform 3 is provided with a U-shaped groove, equipment can translate into the main body rack 1 through the U-shaped groove, and rotation conditions are provided for the single body test of the crane. The third layer working platform 3 of the main body rack 1 is provided with a vertical supporting seat, an inclined supporting seat 8, a turning-over flange 6 and a rotary hinge 7, wherein the vertical supporting seat and the inclined supporting seat 8 are of split detachable structures. The vertical supporting seat is a supporting element during equipment assembly, the inclined supporting seat 8 is a supporting element which is rotationally fixed after equipment assembly is completed, and the inclined supporting seat 8 is a first supporting fixed point in a rotating and inclining state of the elevator. Because the weight of the elevator is concentrated on the upper part, the gravity center is deviated, the elevator is kept fixed after rotating to a specified position, a top fixing frame 5 is arranged on a fourth layer of platform 3 on the main body rack and used as a second supporting fixed point, and the top fixing frame 5 is fixedly connected with the upper part of the elevator through bolts.
The small supporting platform is provided with a set of bottom inclined fixing device which is used as a third supporting fixing point in the rotating inclined state of the elevator.
