Annexation between turn table of the present utility model and supporting device 2 thereof and revolution trailer coupling 5 contained each parts, all identical with aforementioned " the full circle swinging balance crane of band Lifting basket ", annexation between load lifting limiter 11 contained each parts is identical with aforementioned " self-chambering jack up balance crane ", the annexation that hoists between volume machine 6 contained each parts is a known technology, so be not described in detail.
The utility model with said structure is when concrete the use, start the winch 6 that hoists, its hoist rope 65 drives suspension hook 14 can lift by crane weights such as building object, when hoisting capacity is overweight, remaining load lifting limiter 11 plays a role, the braking motor stall of the feasible winch 6 that hoists is to prevent the accident of rushing to summit.The principle of work of revolution trailer coupling 5 of the present utility model and turn table and supporting mechanism 2 thereof is identical with aforementioned " the full circle swinging balance crane of band Lifting basket ", start revolution trailer coupling 5 during work, two revolution hauling ropes 56 are drawing-in motion in the opposite direction, and drawing tension drives revolution upper bracket 201, turn table 202 and service platform 4 and their above complete machine parts are done 360 ° of revolutions around ring-shaped guide rail 206 together.Limit switch 208 on being connected in turn table 202 rotates when spacing collision block 102 on the annular roof plate 101 that is connected in underframe 1 contacts in cw or inhour, make this limit switch 208 that is connected in revolution trailer coupling 2 control circuits disconnect, control circuit being cut off and makes revolution trailer coupling 2 stop drawing-in motion immediately, thus with the turning down motion limits of this machine in 360 ° of scopes.
The self-chambering supernumerary segment of the utility model before the above-mentioned work of formal input is used, the main little gin pole assembly 8 of band lifting stock that relies on is realized.At installation phase, the power of little gin pole assembly 8 is to take from hoist rope 65, it passes in the pipe of gin pole seat 88 and little gin pole 810, and below with top sheave 84 and the last sheave 85 walked around down respectively, the end of hoist rope 65 inserts little suspension hook 87, and with wire clips 86 with hoist rope 65 tail end card jails, catch on column standard knot 3 members such as grade with little suspension hook 87 then, start the winch 6 that hoists, column is increased step by step.Whenever after increasing a column standard knot 3, oneself also will the climb height of a column standard knot 3 of little gin pole assembly 8.Figure 13 represents the process of climbing of little gin pole assembly 8 oneself: little suspension hook 87 is hooked on the cover ear on the little gin pole 810, make hoist rope 65 from descending sheave 84 around coming up, walk around again and hang over the auxiliary movable pulley 811 of joint column standard knot 3 a tops placement topmost, start the winch 6 that hoists then, just can drive little gin pole assembly 8 promotes, during lifting, four root posts that eight rollers 82 of cover support body 81 are pasting column standard knot 3 slide.Owing to the little gin pole assembly 8 that has only of lifting here, so cover support body 81 can be done very lightly, hoisting power is very little.
Install column and arrive after the desired height, lift by crane and install upper frame 9, load lifting limiter 11, equilibrium arm 10, arm of derrick 13 etc. by little gin pole assembly 8 again.Because upper frame 9 arranged, just no longer need the column cap, and the interlock of being convenient to equilibrium arm 10 and arm of derrick 13 works and pulls.Referring to Figure 14, before equilibrium arm 10 is installed, earlier an end of equilibrium arm drag-line 7 and arm of derrick drag-line 12 is contained in the top of equilibrium arm 10, after arm of derrick 13 root hinge pins and equilibrium arm 10 root hinge pins have been adorned, at this moment arm of derrick 13 sagging reversals of the natural order of things can connect the other end and arm of derrick 13 tops of arm of derrick drag-line 12, again the lower end of two balance drag-lines 7 are one and pull stull 16, so that hang bottle gouard moved by hands 15, bottle gouard moved by hands 15 lower ends are connected with service platform 4.Constantly tighten up the drag-line of bottle gouard moved by hands 15, just can get up equilibrium arm 10 and arm of derrick 13 plates gradually.By the time when the lower end of equilibrium arm drag-line 7 can install on the corresponding bearing pin of service platform 4 fixedly, refill two bearing pins, unclamp slack-free bottle gouard moved by hands 15 at last, just install and finished at last.After the installation, just hoist rope 65 can be taken off from little gin pole assembly 8, and be connected to normal mode of operation.
The utility model combines self-chambering supernumerary segment technology and turning down pattern, all transmission devices and counterbalanced weight needn't be promoted, thereby alleviated the weight of climbing greatly, simplified the lifting stock, make that complete machine structure is compacter, weight is lighter, maintenance is convenient, cost is lower, its safety is good, and is strong to the workyard comformability, and samll cities and towns popularize in an all-round way and use in being suitable for very much.Its self-chambering supernumerary segment, the main little gin pole of band lifting stock that relies on is realized, has avoided using expensive hydraulic lifting or whole rising to pull device, this also is the key character that the utility model is different from other downside rotation type electro loop wheel machine.
