Description
Technical field
The utility model relates to a kind of job platform support, mainly is applicable to higher steel work cylindrical shell installation, and the most typical structure is that blast furnace diffuses chimney, and is suitable for the steel cylinder building of other any similar structures.
Background technology
At present, the cylindrical shell steel structure body is installed and is adopted scaffolding, placement platform plate on the scaffold; Scaffold is normally taken cylindrical shell steel work top from ground, and the number of components that constitutes scaffold is bigger, and transportation, loading and unloading are very not square more.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, coal gas diffusion chimney removable job platform support flexibly.
To achieve these goals, the technical solution of the utility model is: coal gas diffusion chimney removable job platform support, it is characterized in that it comprises upper boom, crossbeam, first bolt, hound, second bolt, lower beam, fixedlying connected with the bottom of upper boom in the right part of crossbeam, fixedlys connected with the upper end of lower beam in the left part of crossbeam; The right part of crossbeam, the upper end of hound are provided with first bolt hole respectively, and the bottom of lower beam, the bottom of hound are provided with second bolt hole respectively; Crossbeam passes first bolt hole with hound by first bolt and is connected, and lower beam passes second bolt hole with hound by second bolt and is connected.
The beneficial effects of the utility model are:
1, parts are few, and are simple in structure.
2, applied widely.Be not only applicable to steel stack, the cylindrical shell steel structure body of similar chimney all can adopt.
3, utilize height, effect by force.No matter the how high covering device of cylindrical shell (being made of a pack support and landing slab) gets final product, utilization rate 100% has the powerful superiority of installation exercise and security protection dual characteristics.
4, easy to use, flexibility good.Very easy to use, and can dismantle whenever and wherever possible and install according to user's needs, need not Aided Machine and just can finish by hand.
5, cost is low, income is high.Support is that common shaped steel is welded, but the simplicity of design field fabrication.Adopt this support then to need not to weld again other temporary fixed supports, avoided the waste of interim material.The dual characteristics of operation and security protection also greatly reduces the safety measure expense.

The specific embodiment
As shown in Figure 1 and Figure 2, coal gas diffusion chimney removable job platform support, it comprises upper boom 2, crossbeam 3, first bolt 5, hound 6, second bolt 8, lower beam 9, (as adopting welding) fixedlyed connected in the right part of crossbeam 3, and (left side among Fig. 1 is a left end with the bottom of upper boom 2, the right is a right-hand member), fixedly connected with the upper end of lower beam 9 (as adopting welding) in the left part of crossbeam 3; The upper end of the right part of crossbeam 3, hound 6 is provided with first bolt hole respectively, and the bottom of the bottom of lower beam 9, hound 6 is provided with second bolt hole respectively; Crossbeam 3 passes first bolt hole with hound 6 by first bolt 5 and is connected (bolt screws on nut); Lower beam 9 passes second bolt hole with hound 6 by second bolt 8 and is connected (bolt screws on nut).The upper end of described upper boom 2 is provided with annular safety chain 1.
First fixed head 7, second fixed head 10 respectively with the welding of the outer wall of steel work cylindrical shell 11, constitute first jack between the outer wall of first fixed head 7 and steel work cylindrical shell, constitute second jack between the outer wall of second fixed head 10 and steel work cylindrical shell, first fixed head 7 is positioned at the top of second fixed head 10, and the center line of the center line of first jack and second jack is positioned on the same vertical line.Lower beam 9 inserts in first jack, second jack.
Use (erection sequence and method): step 1: prepare the coal gas diffusion chimney removable job platform support 12 (be called for short support 12, present embodiment adopts 12, below describes by 12 supports 12) more than at least 8; The upper boom 2 of each support 12, crossbeam 3, lower beam 9 be welding fabrication (but field Welding moulding); Step 2: sustained height is along circumference welding 12 first fixed heads 7 (uniform) on the outer wall of steel work cylindrical shell, sustained height is along circumference welding 12 second fixed heads 10 (uniform) on the outer wall of steel work cylindrical shell, last bottom plate respectively keeps sustained height, and three weld all arounds are adopted in fixed head and cylinder body outer wall welding; Step 3: the lower beam 9 of 12 supports 12 is inserted in second jack of first jack, second fixed head 10 of corresponding separately first fixed head 7, by first bolt 5, second bolt 8 hound 6 is connected locking with upper boom 2, lower beam 9 respectively then; Step 4: on the crossbeam 3 of 12 supports 12, lay landing slab 4; Need that all colligation is firm at a certain distance with landing slab and landing slab and crossbeam with iron wire; Step 5: wear annular safety chain 1, pin two and tension with flower basket bolt after the chain closure.Can form a firm overall operation platform after the installation.Wherein landing slab, support (safe chain) are knockdown pieces (first fixed head 7, second fixed head 10 can not pulled down, and weld first fixed head 7, second fixed head 10 up again; First fixed head 7, second fixed head 10 also can cut down respectively), along with the continuous rising of setting height(from bottom) and the change of installation site, this support can be disassembled, install once more at assigned address according to customer requirements, realize job platform automatic lifting, follow one's inclinations mobile, safe and reliable.
