The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.

As shown in Fig. 1 to Fig. 7, chip jacking stock described in the utility model, comprises polylith slice structure; Every slice structure is flats and is welded by steel structure parts; On every slice structure, be provided with connecting joint 2, polylith slice structure is tightened up and is connected and surround enclosed construction by connecting joint 2 detouchables.

So-called slice structure, is the integrative-structure being connected into by welding manner by various steel structure parts, and the whole one-tenth of slice structure flats; Steel structure parts wherein can comprise one or more in main string 3, cross bar 4, brace 5, fixed link 6, and its concrete kind and quantity are selected according to the actual conditions of whole jacking stock and chip mechanism connection location.Connecting joint 2 are that as shown in FIG., connecting joint 2 are generally some connecting panels, are provided with some bolts hole on connecting panel for the interconnective connection structure of slice structure; Or connecting joint 2 can be also the structure similar to flange; When two slice structure assemblings, corresponding connecting joint 2 pairings, then can realize detouchable by bolt and/or bearing pin etc. and tighten up connection.

Jacking stock is to be centered around pylon 7 surroundings in tower crane, so chip jacking stock specifically need to use several slice structures, is mainly that the contour structures by the pylon 7 of tower crane determines; The contour structures of pylon 7 is different, and the quantity of corresponding slice structure can be different, and if pylon 7 is from being vertically seen as triangular structure, when namely the cross-sectional plane of pylon 7 is triangle, corresponding chip jacking stock needs three slice structures; And when the cross-sectional plane of pylon 7 is quadrangle, corresponding chip jacking stock needs four slice structures; In theory, if the cross-sectional plane of pylon 7 is N limit shape, corresponding chip jacking stock needs N piece slice structure.
