Portion arranges suspension bracket by hook activity.
The lifting stage apparatus of above-mentioned chimney derrick, the derrick pull bar is the steel wire rope of diameter 15mm, pacifies on steel wire rope
Dress bottle gouard moved by hands.
The lifting stage apparatus of above-mentioned chimney derrick, the suspension bracket is divided into inside and outside two groups, and internal hanger and outer suspension bracket are pacified respectively
It is mounted in the inside and outside both sides of chimney wall；Every group of suspension bracket is made up of upper and lower two-layer, and between per layer of adjacent suspension bracket scaffold board is laid.
The lifting stage apparatus of above-mentioned chimney derrick, the outside of the outer suspension bracket arranges safety net.
This utility model adopts above-mentioned technical proposal, and by the circular lift frame being suspended on derrick, inside outer lifting, pours
Note chimney wall, as stack shell is stepped up, derrick and hoisting frame are also stepped up, it is not necessary to build the cunning of scaffold and complexity
Mould, saves the material that artificial operation and steel pipe etc. build scaffold, saves man-hour, reduces building cost.There is operation simultaneously
Simply, working security is high, the characteristics of chimney structure quality is good.The vertical lifting equipment of derrick lifts hopper using hoist engine,
It is simple to operation.

Specific embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, this utility model includes derrick 1, derrick pull bar 2, chimney wall 3 and hoisting frame.The derrick 1 is
The foursquare column steel frame construction being welded by angle steel, wherein the foursquare length of side is 1.25m, the specification of angle steel is 80*
8.The inside of derrick is provided for conveying the hopper 6 of material, and the hoist engine of crown lifts hopper by pull rope.Derrick 1
Some groups of derrick pull bars 2 are uniformly arranged in every one side at side wall four sides, derrick pull bar is symmetrical centered on derrick.The well
Frame pull bar is the steel wire rope of Ф 15 (diameter 15mm), and bottle gouard moved by hands 10 is installed on steel wire rope.Every group of derrick pull bar inclines including two
The first different derrick pull bar of rake angle and the second derrick pull bar, the first derrick pull bar and the second derrick pull bar upper end are fixed on well
Frame same position, lower end is connected respectively with hoisting frame.50 ° -90 ° of the scope of derrick pull bar and horizontal direction angle.Wherein with water
Flat angular separation it is big for the first derrick pull bar, angle it is little for the second derrick pull bar.The friendship of the first derrick pull bar and hoisting frame
Joint of the meeting point away from derrick center 0.625m, the second derrick pull bar and hoisting frame by derrick pull bar, is carried away from derrick center 4.7m
The triangular structure for rising frame and derrick composition ensures that hoisting frame stress is steady, safe and reliable.
As shown in Fig. 2 the hoisting frame includes radiation beam 7, annular girder 12, gripper shoe 13 and suspension bracket 8.The radiation beam 7
It is some channel-section steels radially distributed centered on derrick, 16,20 or 24 radiation beams is typically set, it is uniform due to radiating beam
Distribution, makes hoisting frame uniform force.Derrick pull bar 2 is fixed on radiation beam 7.The circle that annular girder 12 is increased successively by three loop diameters
Ring is constituted, and annulus is made up of channel-section steel.Annular girder 12 welds integral with radiation beam 7, radiates the surface laying shape of gripper shoe 13 of beam
Into hoisting frame.The bottom of each radiation beam arranges suspension bracket 8 by hook activity, and 8 points of suspension bracket is inside and outside two groups, internal hanger with
Outer suspension bracket is separately mounted to the inside and outside both sides of chimney wall.Every group of suspension bracket is made up of upper and lower two-layer, the adjacent suspension bracket of upper and lower layer
Between lay scaffold board 9 respectively, operator construct on scaffold board.Suspension bracket 8 is made up of the round steel of Ф 20, and round steel upper end is curved
Into inverted U-shaped hook formation, suspension bracket is set to be hooked on radiation beam and can move along radiation beam.The outside of outer suspension bracket arranges safety net
11, to the safety for guaranteeing operator.
The course of work of the present utility model is described further below：
Reinforcing bar, concrete perfusion are laid on chimney raft 5, funnel base is built.The center of pedestal sets up derrick
1.The radial upper surface for being welded on annular girder of beam 7 is radiated by 24, between radiation beam gripper shoe 13 is laid, make lifting
Frame.Derrick pull bar 2 is installed on derrick, and is connected with hoisting frame.It is responsible for holding and is carried by 16 groups of (per four groups of side) derrick pull bar
Rise the balance of frame.Manually calabash 10 manually pulls upwards hoisting frame during construction.In the bottom mounting suspension of hoisting frame.Operation
Work attaches inside and outside two-layer template on chimney wall, is fixed by anchor ear between template.Concrete is poured into a mould between template, chimney is formed
Barrel 3.With the increase of chimney shaft, diameter is gradually reduced, and the hook of suspension bracket 8 is moved along radiation beam 7 to center, to adapt to cylinder
The change of body.
When needing lift headframe pull bar, per group of the first derrick pull bar is moved up along derrick, the second derrick pull bar is used
To stablize hoisting frame；After first derrick draw rod positions are fixed, the second derrick pull bar is moved upwards up to the first derrick and draws along derrick again
The position of bar.By the alternating movement of two derrick pull bars, the rising of hoisting frame is realized.
