Road 2, car stop 3, weight shift unit 4, fixed anchor plate 5, hydraulic lifting jack 6, prestress wire 7.
Support steel beam 1 is box type structure girder, and totally two, the cylinder head in chimney concrete outer tube wall is arranged by left and right horizontal
（Or chimney top dust stratification platform）It top surface and is mutually parallel, level of the support steel beam horizontal axis perpendicular to the main girder steel of chimney platform
Axis；Flange plate is provided with vertically communicated strip hole to every support steel beam up and down, and the length satisfaction of strip hole is not small
In the distance for waiting for that hoisting steel beam needs horizontal sliding.
1 top surface of support steel beam is disposed with two U-shaped horizontal slides 2 made of channel steel, and two horizontal slides 2 are along support
The 8 both sides horizontal parallel arrangement of strip hole of 1 top flange plate of girder steel, 2 two ends of slideway are equipped with car stop 3.
6 bottom of hydraulic lifting jack is fixedly connected with 5 top surface of fixed anchor plate, if 5 bottom of fixed anchor plate is equipped with
Dry weight shifter 4, weight shift unit 4 is placed in U-shaped slideway 2.
The length of prestress wire 7 should meet maximum lifting height, and the radical of prestress wire 7 should meet maximum and hang
Fill the promotion requirement of load；7 upper end of prestress wire passes vertically through the strip hole 8 and hydraulic pressure of track support steel beam 1
Lifting jack 6 is connected, and 7 lower end of prestress wire passes through bottom anchorage and girder steel end top flange plate phase to be lifted
Even.
Overturn-preventing hook 10 is used for overturn-preventing；One layer of polyfluortetraethylene plate 9 of elongated paving in U-shaped slideway, for reducing cunning
Horizontal frictional resistance during shifting between the idler wheel and slideway of weight shifter.
As shown in figure 4, chimney steel beam hydraulic, which promotes high-altitude integral sliding construction method, specifically includes following steps：
Step 1, assembling hydraulic pressure lift high-altitude integral slipping hanging apparatus.
It is in the venue that support steel beam 1, slideway 2, car stop 3 is assembled integral according to design drawing, it is lifted by crane and is pacified with hoist engine
It is attached to the first top of chimney concrete outer tube wall cylinder, or is arranged in the dust stratification platform girder steel top surface of top inside chimney.By hydraulic pressure
After lifting jack 6, fixed anchor plate 5,4 three of weight shifter assemble in the venue, pacified with hoist engine integral lifting
It is attached on the U-shaped slideway 2 of track support steel beam top surface two.Track is passed through to support from bottom to top 7 upper end of prestress wire
The strip hole 8 of girder steel 1 is attached with hydraulic lifting jack 6.Hydraulic lifting jack 6 passes through hydraulic oil pipe and hydraulic pressure
Driving pumping plant is attached.
Step 2, prestress wire lower end is connect with hoisting steel beam is waited for.
By zero meter face inside girder steel horizontal transport to be lifted to chimney, by the lower end of the two groups of prestress wires in left and right
Head is connect with the hoisting point position of hoisting steel beam two ends is waited for respectively by bottom anchorage.
Step 3, vertical lifting girder steel.
Start hydraulic power unit driving hydraulic lifting jack work, it is flat that chimney to be lifted is promoted by prestress wire
Platform girder steel slowly rises, until girder steel bottom surface absolute altitude is higher by concrete chimney outer barrel wall circular bracket top surface at design installed height mark
When 30 ~ 50mm of absolute altitude, stops girder steel and promoted.
Step 4, high-altitude integral level slides girder steel.
With two chain blocks（Or hoist engine）Synchronize the hold-down support of horizontal drag hydraulic lifting jack in the same direction bottom
Plate, to drive slideway horizontal sliding of the weight shifter along support steel beam top surface.In slipping, weight shifter support solid
Determine support plate and hydraulic lifting jack, hydraulic lifting jack proposes girder steel integral level displacement by prestress wire,
Up to girder steel horizontal sliding to design position.
Step 5, steel girder erection is in place.
Hydraulic power unit drives hydraulic lifting jack oil cylinder flexible, drive prestress wire carry girder steel decline 30 ~
50mm, until girder steel is in place on the annular bracket built-in fitting of installation site.
Step 6, the reversed horizontal sliding of hanging apparatus is resetted.
Wait for that steel girder erection is in place, after the fully relaxed unloading of steel strand wires, by prestress wire lower end and girder steel junction
Disintegrate and detach, drives the flexible drive prestress wire of hydraulic lifting jack oil cylinder to decline falling by hydraulic power unit and reset；
Reversed Level Promoting hydraulic lifting jack, makes hanging apparatus（Including：Weight shifter, fixed anchor plate, hydraulic pressure lift are very heavy
Top and steel strand wires）Horizontal slide reverse shuffle along support steel beam top surface is to initial starting slip locations.
Step 7, action of the step 2 to step 6 is repeated, lower layers platform steel is successively lifted by top-down sequence
Beam.
Repeat the above steps 2 to step 6 action, by top-down sequence successively by remaining each same axis of layer platform
The girder steel sliding and lifting installation of position is in place.For the girder steel of lighter in weight, also can allow to lift by crane within the scope of load, by lower layer
More girders of platform are connected by steel wire rope while being lifted by crane, slide installation up and down, to accelerate to lift speed, improve construction work
Effect.
Step 8, sliding and lifting device is removed, next engineering is remained and re-uses.
After the completion of steel beam lifting, prestress wire, hydraulic lifting jack, hold-down support are removed successively with hoist engine
Plate, weight shifter, support steel beam, keep the slide device of dismantling, remain next engineering and re-use.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements and retouch, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
