detailed description

As shown in Figures 1 to 2, a lifting platform device for shaft construction includes a platform truss 1, a fence 2 installed around the platform truss 1 and a panel 3 installed on the platform truss 1, and multiple A guide pulley 4 and a top support mechanism 5, the platform truss 1 is symmetrically installed with multiple working lugs 11, the working lugs 11 can be connected with the embedded parts in the shaft, the platform truss 1 is symmetrically installed with multiple lifting lugs 12, the lifting lugs Ears 12 are used for the movement of the lifting platform. The fence 2 is welded by circular steel pipes according to the boundary of the platform truss 1 to protect construction personnel.

In a preferred solution, the platform truss 1 is spliced by double-channel steel in a well shape, and the double-channel steel is connected by bolts and nuts. Channel steel can also be welded on the double-channel steel well-shaped structure to achieve structural reinforcement. Compared with the frame structure, the structure is lighter, the processing is simple, and the stability of the platform can be guaranteed, which greatly saves the profile.

There are 8 working lugs 11 in total, 6 of which are symmetrically distributed on the periphery of the platform truss, and 2 are symmetrically installed on the web of the double channel steel. There are 4 lifting lugs 12 in total, which are symmetrically installed in the connecting gap of the double channel steel. Correspondingly, the panel 3 is provided with holes corresponding to the working lugs 11 and lifting lugs 12 .

The preferred solution is as shown in Fig. 2, the supporting mechanism 5 is installed along the radial direction of the center of the platform, and the supporting mechanism 5 includes a supporting base 51, a supporting sleeve 52, a screw rod 53, a nut 54 and a bracket 55, and the bracket 55 Fixed on the platform truss 1 , the supporting base 51 is connected to one end of a screw rod 53 through a supporting sleeve 52 , and the screw rod 53 is connected to a bracket 55 through a nut 54 . After the nut 54 is loosened, the distance that the screw rod 53 protrudes can be adjusted so that the supporting base 51 is in contact with the shaft wall.

The guide pulley 4 is welded along the radial direction of the platform center, the sliding direction of the guide pulley 4 extends along the shaft direction, and the number of the guide pulley 4 is selected as 8.
