The barrier-striding type supporting leg 1.3 automatically rebounds after contacting the lower part of the wall-striding attaching bracket 6.1, recovers after striding over the wall-striding attaching bracket 6.1, can be placed on the wall-striding attaching bracket 6.1, and is fixed through the locking bolt 8. The front end of the lower part of the wall-attached bracket 6.1 (namely the position contacted with the barrier-striding type supporting leg 1.3) is provided with a roller 10 for buffering, and hard contact is reduced.
In order to install the truss structure 2, the bottom platform 1 is correspondingly provided with a butt joint sleeve 7, the butt joint sleeve 7 is welded on the bottom platform 1 in advance, and a triangular stiffening plate is welded to increase rigidity. The gap between the bottom platform 1 and the side wall of the elevator shaft is sealed by a movable turning plate 1.4, and the movable turning plate is connected with the bottom platform 1 by a hinge 1.5. When the movable turning plate is in the preparation stage before lifting, the movable turning plate 1.4 is erected, and after the movable turning plate climbs to the right position, the movable turning plate 1.4 is lowered.
The truss structure 2 comprises a horizontal truss 2.1, a vertical truss 2.2, an operating platform 2.3, a cross brace 2.4, a pedestrian ladder 2.5 and the like. In order to ensure the stability of the frame body, the horizontal truss 2.1 and the vertical truss 2.2 are hinged to form an outer frame and inner frame truss stable structure system, and the hinged form is screw connection. The truss structure 2 is twice the story height, considers that actual site operation needs the cooperation construction of lower floor, sets up operation platform 2.3 on corresponding operation layer. In order to facilitate the up-and-down circulation of personnel, a group of pedestrian climbing stands 2.5 are arranged in the inner frame system to serve as an up-and-down channel, and the pedestrian climbing stands 2.5 are provided with protective rings at intervals. The two opposite sides of the truss structure 2 are vertically provided with guide rails 2.6, and the guide rails 2.6 are uniformly hinged with the truss structure 2. The guide rail 2.6 is formed by splicing section steels, a sealing plate 2.7 is arranged on the inner side, and a plurality of uniformly distributed anti-falling pin shafts 2.8 are symmetrically arranged on the outer side.
The electric lifting system 3 comprises electric lifting means 3.1 and lifting slings 3.2, the electric lifting means 3.1 being suspended from lifting brackets 3.3 on the top platform 2.9. The electric lifting device 3.1 adopts an electric hoist. The lifting support 3.3 is provided with a hook 9, and the hook 9 and the lifting support 3.3 are fixed by bolts. One end of a lifting sling 3.2 is arranged on the electric lifting device 3.1, the other end of the lifting sling 3.2 bypasses a fixed pulley 3.4 on the bottom platform 1 and is fixed on a lifting hanging seat 6.2, and the lifting hanging seat 6.2 is fixed on the side wall of a shaft of an elevator shaft and is at the same height with the top platform 2.9.

And the wall-attached anti-falling system 4 is arranged along the symmetrical direction of the elevator shaft. The wall-attached anti-falling system 4 consists of a rigid support 4.1, a guide wheel 4.2, an anti-falling unloading supporting device 4.3 and a linkage anti-falling device 4.4. When the working platform climbs, the guide wheels 4.2 limit the left and right deviation of the guide rails 2.6 but do not limit the up and down lifting. The anti-falling unloading jacking device 4.3 utilizes the spring to preset an inclination angle and freely approaches the anti-falling pin shaft 2.8 in the guide rail 2.6, so that the friction force between the anti-falling unloading jacking device and the anti-falling pin shaft 2.8 is reduced, and the anti-falling unloading jacking device can move more smoothly. When the guide rail 2.6 moves upwards, the anti-falling pin shaft 2.8 pushes the anti-falling unloading supporting and ejecting device 4.3 to move along the preset inclination angle and pushes the linkage anti-falling device 4.4 to rotate. When the guide rail 2.6 moves downwards, the groove opening of the anti-falling unloading supporting device 4.3 supports against the anti-falling pin shaft 2.8 in the guide rail 2.6, and simultaneously the linked anti-falling device switch is triggered to limit the guide rail 2.6 to fall.
In order to ensure that the lifting speed of the electric lifting device 3.1 at the corresponding position in the lifting process is consistent and the operation is normal, the working platform is controlled in real time by an intelligent synchronous control system, a main control cabinet and a sub-control box are respectively arranged, namely, the sub-control box is arranged beside the electric lifting device 3.1 and can monitor the lifting speed, the lifting moment and the lifting state in real time. The main control cabinet is provided with a remote controller, so that the remote control can be operated remotely, and the support body can climb without climbing. Protective railings are arranged on the middle operating platform and the top operating platform of the tool type truss and used as edge protection.
Before the operation platform is lifted, the operation platform is lifted by 30mm in advance, the locking bolt 8 on the barrier-striding type supporting leg 1.3 is taken out after the operation platform is stabilized, the operation platform is in a state of waiting to rotate, and meanwhile, the anti-falling unloading supporting jack 4.3 is loosened and then lifted by the electric lifting device 3.1. The anti-falling unloading jack 4.3 can not be separated from the anti-falling pin shaft on the guide rail when being lifted. The wall-attached bracket 6.1 and the wall-attached anti-falling system 4 on the upper layer are pre-buried and positioned before lifting. After the operation platform is lifted, after the obstacle-crossing type supporting leg 1.3 reaches a preset position of the wall-attached bracket 6.1 of the lifting layer, the locking bolt 8 is adopted to lock the lifting layer, and the anti-falling unloading supporting device 4.3 of the lifting layer props against the anti-falling pin shaft 2.8 to complete the lifting. And repeating the steps and climbing until the construction of the elevator shaft is completed.
