Abstract
The utility model discloses a hydraulic jacking device of the inner steel cylinder of a chimney, which comprises a piston ring, wherein the piston ring is connected with a tensioning device; the tensioning device is connected with one end of a radial jack; the other end of the radial jack is arranged on a channel steel bracket; and a vertical jack is arranged below the piston ring. Compared with the air jacking inverted installation construction, the device is characterized in that the center of gravity of the chimney is still on the lower part. The hydraulic jacking device has the characteristics of high equipment installing speed, high and stable jacking speed and the like, is convenient to operate, is convenient to disassemble equipment and can be reused time after time. During construction, the device has the advantages of more reasonable technical flow and high work efficiency, engineering quality and construction safety are easy to control, engineering cost is effectively lowered, energy is saved, and the environment is protected.
Description
Technical field
The utility model relates to a kind of chimney construction device, is specifically related to the lift-up device of using in a kind of inner core hydraulic lifting method.
Background technology
The construction of large thermal power plant chimney titanium steel inner core is that thermal power plant builds emphasis and the difficult point in the construction.Available technology adopting be air-rise invert method, as application number be " 93114578.3 ", that name is called the patent of invention of " fan-shaped cellular-type steel stack such as full circle and air-rise upside-down construction method thereof " is said.Center of gravity is on chimney top in the construction in this method, and the plant equipment of requirement is more, and installation rate is slow, dangerous high.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of chimney steel inner cylinder hydraulic jacking device is provided, and its installation rate is fast, handling safety.
The technical scheme of the utility model realizes in the following manner: a kind of chimney steel inner cylinder hydraulic jacking device; Comprise piston ring, piston ring links to each other with swelling device, and swelling device links to each other with jack one end radially; Radially the jack other end is located on the channel-section steel support, and the piston ring below is provided with vertical jack.
The piston ring top is welded with limited slip block.
Said radially jack is ten, and said vertical jack is ten.
The construction of this device and air-rise invert method is compared the chimney center of gravity all the time in the bottom, have that the equipment installation rate is fast, jacking speed is fast and steadily, be convenient to operation, equipment convenient disassembly, characteristics such as can repeatedly utilize.So technological process is more reasonable during the construction of this device, work efficiency height, workmanship and construction safety are controlled easily, reduce engineering cost, energy-conserving and environment-protective effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model user mode sketch map.
Fig. 3 is the structural representation of the utility model embodiment 2.
The specific embodiment
As depicted in figs. 1 and 2, a kind of chimney steel inner cylinder hydraulic jacking device comprises piston ring 3; Piston ring 3 links to each other with swelling device 7; Swelling device 7 links to each other with jack 1 one ends radially, and radially jack 1 other end is located on the channel-section steel support 2, and piston ring 3 belows are provided with vertical jack 5.Described piston ring 3 is high-strength rubber pads.
Described in the present embodiment radially jack can be 6 ~ 10 with vertical jack, preferably be 10.
The utility model use is following; Piston ring 3 links to each other with swelling device 7 through bolt, with hydraulic radial jack 1 piston ring is held out against, and piston ring 3 dependence frictional force and steel inner cylinder cylindrical shell 4 fuse; 10 vertical hydraulic jack 5 of piston ring 3 below symmetrical placement; When promoting steel inner cylinder cylindrical shell 4,, steel inner cylinder cylindrical shell 4 is risen thereupon get final product with vertical hydraulic jack 5 jacking piston rings 3.After rising finished, hydraulic radial jack 1 unclamped and can make piston ring 3 break away from steel inner cylinder cylindrical shells 4.
As shown in Figure 3, piston ring 3 tops are welded with limited slip block 6.Add after the limited slip block 6, can further strengthen the safety of operating.
