Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below by the technical side to the present invention
Case is described in detail.Obviously, described embodiment is only a part of embodiment of the present invention, and not
It it is whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making wound
Other embodiments all obtained by the premise of the property made work, broadly fall into the scope that the present invention is protected.
A kind of elevator combination type entirety lifting operation platform, as shown in Figure 1, this platform include framework 1,
Panel 2, supporting leg 3, crosshead 4, as shown in Figure 2, described framework 1 include an auxiliary support 13, a pair
Isometric stull 11 and a pair isometric perpendicular support 12, described stull 11 and described perpendicular support 12 are welded into a square
Shape frame, described auxiliary support 13 is welded on the middle part of described rectangle frame, and parallel with described perpendicular support 12;Described
Plate 2 is welded on above described framework 1;Described supporting leg 3 has four, and described stull 11 is a hollow, institute
State supporting leg 3 to can be inserted in described stull 11;Described crosshead 4 is arranged on panel 2, some steel pipes lead to
Cross pipe fitting connection to build.
Described stull 11 is a rectangular steel tube, and described rectangular steel tube is formed by two isometric channel-section steel butt welding.Institute
State perpendicular support 12 to be made by I-steel.Described panel 2 is made up of checkered steel plate, and the thickness of checkered steel plate is
4mm.Four suspension ring 6 it are additionally provided with, for the lifting of platform on described platform.Arrange on described supporting leg 3
There is anti-sideslip part 31, be positioned at the lower surface of supporting leg 3.
Embodiment one
A kind of elevator combination type entirety lifting operation platform, described perpendicular support 12 is made up of 2 I16 I-steel,
Described stull 11 is right by twoChannel-section steel is made, and described auxiliary support 13 is by 1Channel-section steel, described panel 2 by
4mm checkered steel plate is made, and described supporting leg 3 has 4, uses 900mm long I14 I-steel, described supporting leg
3 with hoistway inwall at lower end use L100*8, long 100mm angle bar firm welding, the girder that prevents from encorbelmenting breaks away.
Described crosshead 4 uses Φ 48mm × 3.0mm steel pipe.
First, determining platform size according to lift shaft dimensions, platform is 100mm away from the borehole wall.By 4Groove
Steel divides two groups to carry out butt welding, and formation 160mm*128mm rectangular opening is easy to I14 I-steel supporting leg 3 and is inserted.
Then 2 I16 I-steel are existed respectivelyThe welding of channel-section steel two ends forms rectangle frame.In the middle of platform framework 1
Weld one parallel with I16 I-steelChannel-section steel, as auxiliary support 13, strengthens platform and bears from upper shelf
The ability of body load.Fix with steel plate full weld in the range of commissure anomaly edge of table 500mm of channel-section steel butt welding.
Panel 2 uses 4mm thickness checkered steel plate firm with platform framework 1 full weld.By clear for the steel platform surface made
Reason is clean, brush red lead anti-corrosive paint twice.
Installing and using of platform, during use, it is ensured that periphery beam slab concrete strength reaches certain intensity.By tower
Hang steel platform Integral lifting (by the lifting of 6 four, suspension ring) to construction of lift well position liftoff 500mm,
Then steadily fall after penetrating I14 I-steel supporting leg 3, it is ensured that what I14 I-steel supporting leg 3 was firm is shelved on week
On side bar plate.Setting up crosshead 4 on steel platform, support body uses Φ 48mm × 3.0mm steel pipe to set up.Take
