Further, described carriage assembly also include cross bar 1-4, described cross bar be laterally fixedly arranged on the first support bar 1-2 with
Between second support bar 1-3, make bracing frame more stable.
Further, the end being positioned proximate to described support bar that described cross bar and the first support bar, the second support bar connect
End.
Further, described carriage assembly also includes the column 1-7 being vertically arranged crossbeam middle position.
The connection of device support body all uses Q235B level H profile steel to be welded and fixed.
Embodiment two
When suspension centre stress is more than 10T, crossbeam can be set up between device support body, increase suspension centre, reduce single suspension centre
Load-bearing, as used embodiments of the invention two devices, as in figure 2 it is shown, the entire lowering Bailey bracket of the present embodiment two, section steel platform
Group hoist device, including crossbeam 2-1；Chain block 2-6 is installed on crossbeam 2-1, solid by chain block 2-6 cable wire
Fixed component to be lifted.
Further, described carriage assembly includes the first support bar 2-2, the second support bar 2-3 and the 3rd support bar 2-4,
Described carriage assembly bottom arranges backing plate 2-5, described first support bar 2-2 and is vertically arranged, the second support bar 2-3, the 3rd support
Bar 2-4 is symmetricly set in the first support bar both sides and is formed with an angle with the first support bar.
The connection of device support body all uses Q235B level H profile steel to be welded and fixed.
During actually used, in this device, suspension centre must is fulfilled for lift heavy requirement, and often suspension centre across Bailey bracket must not lack
In 3, it is simple to adjustment at any time, it is to avoid single suspension centre declines too fast, causes whole platform inclination.
During practice of construction, according to lattice column, the distribution situation of bracket, determine lifting elements, according to lifting elements internal loading
Distribution situation, determines suspension centre, and by checking the load of entire lowering, selected optimal group hangs scheme, it is ensured that being subject to of each suspension centre
Power is respectively less than 10T.
Entire lowering Bailey bracket described in embodiment one, the construction method of group's hoist device of section steel platform, including with
Lower step:
A. the making of steel bracket: support physical dimension 2510mm (wide) * 6460mm (length) * 3320mm (high), its middle cross beam
The second support bar 1-3 that 1-1 is formed with an angle with vertically disposed first support bar 1-2 and the first support bar 1-2 is welded into
Support, support bottom is fixedly installed backing plate 1-5 (backing plate is 300*300*20), and support uses Q235B level H profile steel, and steel bracket should
In altitude range, chain block 1-6 (10T) can be fixed, and guarantee operation height；Close on described first support bar 1-2, second
Being welded with a cross bar 1-4 at the bottom position of strut 1-3, its middle cross beam uses the specification of HW300*200*8*12, strut and horizontal stroke
Bar uses the specification of HW150*150*7*10.
B. suspension centre determines and support is installed: according to each structure post, the distribution situation of bracket, determine lifting elements, according to lifting
Unit internal loading distribution situation, determines suspension centre, and by checking the load of entire lowering, selected optimal group hangs scheme, it is ensured that every
The stress of individual suspension centre is respectively less than 10T.When suspension centre stress is more than 10T, crossbeam can be set up between support, increase suspension centre, reduce
The load-bearing of single suspension centre, support is arranged on often across Bailey bracket two ends, when Bailey bracket span is bigger, on the crossbeam between support
Increase suspension centre；

Sling, after Bailey bracket is separated with bracket, remove bracket, it is ensured that when platform declines, bottom clear.In order to not destroy shellfish thunder
Frame, each suspension centre bottom uses H profile steel stress；After bracket is removed, Bailey bracket, section steel platform pass through group's hoist, are suspended in sky
In, for guaranteeing each suspension centre uniform descent, pull each calabash chain simultaneously, and level monitoring point is set on hoist lifting hook, often
Decline 100mm, carry out leveling；
D. platform removal: after Bailey bracket, section steel platform drop to safe location, arranges steel track, track at platform upper
Ride upon on lattice column, utilize pulley suspension hook to be sling by shaped steel, guarantee pulley jib by rail transport to material hoisting port, material
Hook free-running operation, can lay hoist engine as power in track one end.
Embodiments of the invention are in work progress:
1) high-altitude working safety hidden danger is solved
Inverse when making structure, putting up platform position, high-altitude on lattice column, group's hoist by each lifting elements slowly,
Drop to safe location smoothly, it is to avoid the security risk of high-altitude dismantling.Whole decline process, operator are positioned at initial layer structure
Floor top, it is ensured that personnel's job safety.
2) solve structure to close, heavy component handling difficult point
Inverse after structure construction completes, the heavy component of Bailey bracket, section steel platform combination, affected by superstructure closing,
Large-scale Hoisting equipment, direct handling can not be used, use pulley guide rails to move heavy component to material hoisting port, implement to hang
Fortune, solves structure and closes, heavy component handling difficult point.
