Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 to Figure 3, for the tripod operation platform structure of last furnace shell, comprise tripod 1, earphone plate 2, springboard 3 and cylindrical shell 4; Described A-frame 1 comprises base plate 12, gripper shoe 13, junction plate 14, described base plate 12 is arranged on gripper shoe 13 and junction plate 14, described base plate 12, gripper shoe 13, junction plate 14 are interconnected to form triangle between two, described base plate 12 is provided with railing 11 away from one end of junction plate 14, and described junction plate 14 upper ends are provided with hangers 141; Described earphone plate 2 centre positions are recessed to form projection 21 to a side, described earphone plate 2 is all welded on external surface or the inner surface of cylindrical shell 4, and level height is identical, described hangers 141 is arranged in the gap forming between the external surface of projection 21 on earphone plate 2 and cylindrical shell 4 or inner surface; Described springboard 3 is set up on the base plate 12 of adjacent two A-frames 1.
Described earphone plate 2 is welded on cylindrical shell 4, and forms the gap that articulates of A-frame 1 with cylindrical shell 4.Gripper shoe 13 support baseboards 12 on described A-frame 1 and connection junction plate 14, be provided with hangers 141 and be connected with cylindrical shell 4 by hangers 141 on described junction plate 14.A-frame 1 is fixed on cylindrical shell 4, on the base plate 12 of adjacent two A-frames 1, sets up springboard 3.Described base plate 12 mainly plays the effect of supporting springboard 3.
Set up A-frame operation platform on cylindrical shell 4 time, first earphone plate 2 is welded on cylindrical shell 4, and the level height of described each earphone plate 2 is identical, between earphone plate 2 and cylindrical shell 4, forms and articulate gap.Then the hangers on A-frame 1 141 is hung as in this gap.A-frame 1 is arranged on cylindrical shell 4.Finally on the base plate 12 of adjacent two A-frames 1, set up springboard 3, complete the overlap joint of operation platform.
Adopt the tripod operation platform structure for last furnace shell described in this utility model, can reduce construction volume, overlap joint easily and fast.Thereby reduce the cost of erection construction platform on cylindrical shell 4; Fitting operation is easy, is conducive to Fast Installation, saves the engineering time, increases work efficiency, and has reduced cost.While dismounting, only springboard 3 and A-frame 1 need be hung out from top simultaneously, dismantle easy.
As shown in Figure 1 and Figure 2, in order to make to improve its stability after the tripod operation platform structure installation for last furnace shell, the lower end of described junction plate 14 is provided with backplate 142, and described backplate 142 and hangers 141 are positioned at the homonymy of junction plate 14, and described backplate 142 contacts with cylindrical shell 4.Owing to being provided with backplate 142 in the lower end of junction plate 14, backplate 142 contacts with cylindrical shell 4.Therefore a weight part for whole A-frame 1 acts on cylindrical shell 4 by backplate 142, has shared the gravity acting on hangers 141.Thereby make structure more stable, improved the stability of this structure.
As shown in Figure 1 and Figure 2, in order to improve the safety for the tripod operation platform structure of last furnace shell.The lower end of described railing 11 is connected with base plate 12, and upper end is provided with through wires hole 111.By put on safety rope in through wires hole 111; can in the time of unexpected freeing, play a protective role; can make the balance of total better by safety rope simultaneously, be conducive to structure and keep stable, improve the safety for the tripod operation platform structure of last furnace shell.
Firm in order to make for tripod operation platform structure Stability Analysis of Structures in the time bearing larger load of last furnace shell, be not prone to distortion.Described base plate 12, gripper shoe 13, junction plate 14 connection are between any two welding.Described base plate 12, gripper shoe 13, junction plate 14 connection between any two can be bolted.Because the large requirement of strength to bolt with bolts of the active force between described base plate 12, gripper shoe 13, junction plate 14 is higher.With boltsly also need to punch at base plate 12, gripper shoe 13, junction plate 14, complicated operation.Adopt welding not only can ensure bonding strength, simultaneously easy and simple to handle, convenience quick for installation.
Application examples one
First the position that will set up platform when construction on the cylindrical shells 4 such as blast furnace, hot-blast stove, the gravitational precipitator earphone plate 2 of burn-oning.
The low 100mm of the aspect ratio blast furnace podium level left and right of earphone plate 2, the spacing between adjacent earphone plate 2 is determined according to the diameter of the length of springboard 3 and cylindrical shell 4.Such as springboard, the barrel diameter of length 2m are 10m, earphone plate 2 general interval 1.5m between adjacent two earphone plates 2 while being arranged on cylindrical shell 4 external surface, earphone plate 2 general interval 1.8m between adjacent two earphone plates 2 while being arranged on cylindrical shell 4 inner surface.
After earphone plate 2 is welded, in the gap that the projection 21 that the hangers of A-frame 1 141 is arranged on to earphone plate 2 and cylindrical shell 4 form, and on the base plate 12 of adjacent two A-frames 1, spread double springboard 3, in through wires hole 11, put on safety rope.
When dismounting, A-frame 1 is from the hook pull-out for top of cylindrical shell 4, and earphone plate 2 is stayed on cylindrical shell 4 and do not affected the appearance.
By the application on last furnace shell by the tripod operation platform structure for last furnace shell described in the utility model, thus less on last furnace shell the construction volume of building platform, saved cost; Rapid and convenient is installed simultaneously, has improved operating efficiency.
