Detailed Description

The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the lifting device comprises a supporting unit, a lifting unit and a vertical transportation platform 1, wherein the supporting unit consists of a plurality of vertical first supporting masts 2 and a plurality of top beams 3, the plurality of top beams 3 are erected at the upper ends of the plurality of first supporting masts 2, the plurality of top beams 3 are built according to the outline of a building, a plurality of groups of trussed vehicle tracks 4 are installed on the top beams 3, and each group of trussed vehicle tracks 4 comprises two trussed vehicle tracks which are arranged side by side; the lifting unit comprises a truss car 5 and a crane 6 arranged on the truss car 5, and the truss cars 5 can run on each group of truss car tracks 4; the vertical transportation platform 1 is arranged on the first supporting mast 2 and can climb upwards; arc-shaped conversion tracks 7 are arranged among the plurality of groups of truss car tracks 4, two ends of each conversion track 7 are respectively connected with the two groups of truss car tracks 4, and the truss cars 5 can be converted among the truss car tracks 4 through the conversion tracks 7.

The outer side of each conversion track 7 is fixed with a support frame 8, two ends of each support frame 8 are respectively provided with a second support mast 9 fixed on the top beam 3, and two ends of each support frame 8 are respectively lapped on the corresponding second support mast 9 and can climb upwards; support frame 8 is used for supporting conversion track 7 and guarantees conversion track 7's stability, and support frame 8 upwards climbs when conversion track 7 does not use and makes conversion track 7 rise to back timber 3 top to not influence the normal construction on construction layer, when the purlin car 5 need change between two sets of purlin car tracks 4, thereby corresponding support frame 8 moves down and makes conversion track 7 connect two sets of purlin car tracks 4 in two sets of purlin car tracks 4 parallel and levels.

One end of each group of the truss car tracks 4 connected with the conversion track 7 is provided with a transition track 10, and the truss car tracks 4 are smoothly connected with the conversion track 7 through the transition tracks 10.

The first supporting mast 2 and the top beam 3 are assembled in a modularized mode and can be built flexibly according to the building shape.

The first supporting mast 2, the top beam 3, the second supporting mast 9 and the supporting frame 8 are all steel structures.

The climbing device for the vertical transportation platform 1 and the support frame 8 is the prior art, and is not described in detail in the application.

The working process of the invention is described below by taking a Y-shaped building as an example: during construction, a supporting unit is built according to the building outline, the truss car tracks 4 on the top beam 3 are divided into three groups, namely an upper group, a lower group and a lower group, the conversion tracks 7 are arranged in three groups, and can also be arranged according to the actual condition, if the truss cars 5 only need to be converted on the two groups of truss car tracks 4 at the lower left and the lower right, only a group of conversion tracks 7 for connecting the lower left and the lower right are required to be arranged.

During normal construction, conversion track 7 upwards climbs along second support mast 9, avoid influencing the normal construction on construction layer, perpendicular transport platform 1 promotes the material to construction layer, purlin car 5 and loop wheel machine 6 carry out the handling material on purlin car track 4, when purlin car 5 needs to transport between different group purlin car track 4, for example purlin car 5 need follow the lower right transfer to the lower left purlin car track 4 on, make and connect the lower right and lower left conversion track 7 and descend to with purlin car track 4 parallel and level, connect lower left and lower right purlin car track 4, purlin car 5 can follow conversion track 7 and transfer to lower left purlin car track 4 from lower right purlin car track 4 this moment, make after the transfer completion conversion track 7 climb.
