Detailed description of the invention
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation, some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that not departing from spirit and scope of the present utility model, can revise described embodiment by various mode.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
Large-scale chimney construction stage apparatus, comprise that diameter is less than the operation platform frame of chimney minimum diameter, as shown in Figure 1, described operation platform frame is circular disc type template operation platform frame, comprise and be the main stress bar 11 that groined type is fixed together, described main stress bar 11 adopts larger cross-section shaped steel, between described main stress bar 11, be connected with the connecting rod 12 that is net distribution, described connecting rod 12 adopts small cross sections shaped steel, and the outer of described main stress bar 11 and described connecting rod 12 is fixedly connected with circular connecting ring 13.
On described operation platform frame, be equipped with frame plate as working face (not shown); On the chimney outer tube wall 5 at the top end opening place of chimney, day beam 2 is installed, between described sky beam 2 and described operation platform frame, lifting device is installed, as shown in Figure 2, described lifting device comprises wire rope 31 and is arranged on described day two fixed pulleys 32 on beam 2, on described wire rope 31, movable pulley 33 is installed, one end of described wire rope 31 is fixedly connected with described day beam 2, the other end of described wire rope 31 is walked around successively described movable pulley 33 with two described fixed pulleys 32 and is connected with power set, and power set can adopt hoist engine; On described movable pulley 33, suspension hook 34 is installed; The main stress point of described operation platform frame is provided with hanger (not shown), and described hanger is connected with suspension hook 34 by wire rope 31.
Certainly, operation platform frame described in the utility model also can adopt truss-like operation platform frame, as shown in Figure 3, comprise the two-layer main backstop be arrangeding in parallel up and down 41, between two-layer described main backstop 41, be fixedly connected with some connecting rods 12, the Extension support 42 extending is laterally installed between the outer of two-layer described main backstop 41, and the upper surface of described Extension support 42 flushes with upper strata main backstop 41.
When construction, construction platform device is installed on day beam 2 by lifting device, and the vertical position of construction platform device can regulate according to construction requirement; The utility model does necessary loading test before use, after pass the test, just can come into operation.The utility model is made simple, less with material, is used to complete rear material and can has enough to meet the need use; Easy to use, auxiliary hoist engine can reach use function; Set up operation side, ensure construction safety, accelerating construction progress.The utility model compactness rational in infrastructure, flexible adjustment, builds conveniently, has shortened the construction period, has improved efficiency of construction.
Description of the present utility model provides for example with for the purpose of describing, and is not exhaustively or by the utility model to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the utility model design to be suitable for the various embodiment with various amendments of special-purpose.
