Description

Technical Field

[0001] The utility model relates to an absorption tower installation construction device, in particular to a hydraulic jacking support frame for a variable diameter section of an absorption tower. Background Art

[0002] With the continuous progress of social science and technology, the absorption tower body installation industry has also undergone rapid changes. At present, the installation of the absorption tower body mostly adopts the hydraulic jack reverse installation construction process, but there is a rather difficult technical problem in the construction process, which is the jacking method for the variable diameter section. The variable diameter section is a key structural part where the small diameter cylinder section of the absorption tower body transitions to the large diameter cylinder section. The difference in the upper and lower radii of this part is relatively large. However, the protruding length of the jack tongue of the hydraulic jack is only about 200 millimeters. When encountering the installation of the conical section, the construction team must move the jack twice to realize the jacking of the variable diameter section and the large diameter cylinder section of the tower body. Moreover, when moving the jack, it is necessary to open holes in the variable diameter section so that the hydraulic jack can be close to the large diameter cylinder section of the tower body for jacking installation. If the jack is not moved, when installing the variable diameter belt, a false cylinder is made to lift the cylinder body. This method uses a lot of temporary materials, and the installation and removal of the false cylinder are both time-consuming and laborious. Summary of the Invention

[0003] In view of the above problems, the utility model provides a jacking support frame. By setting a hydraulic support frame in the variable diameter section of the absorption tower, adding reinforcement measures, and jacking in sections, the middle variable diameter section and the lower large diameter cylinder section are installed in a reverse manner, reducing the tediousness of moving the jack twice and avoiding the damage to the tower body caused by jacking and opening holes, thereby improving the operation efficiency and reducing the construction cost.

[0004] The purpose of the utility model is achieved as follows. A hydraulic jacking support frame for a variable diameter section of an absorption tower includes vertical support rods and hydraulic jacks. The two sides of the vertical support rods are connected to adjacent vertical support rods through cross beams in sections from top to bottom. Horizontally support rods are connected to the inner sides of the vertical support rods in sections from top to bottom. Diagonal support rods are connected above the horizontally support rods. The outer ends of the horizontally support rods and the diagonal support rods are connected to the variable diameter conical wall plate and the lower straight cylinder wall plate in sections from top to bottom. The hydraulic lifting rod slider arranged inside the hydraulic jack is connected to the bottom of the lower vertical support rod.

[0005] Further, the vertical support rod is of a U-shaped column structure, with a top plate arranged at its upper end and a bottom plate arranged at its lower end. Inner reinforcing ribs are fixedly arranged inside the U-shaped column on the upper surface of the bottom plate. One side of the lower end of the inner reinforcing rib is fixedly provided with a bottom side reinforcing plate. The bottom end of the bottom side reinforcing plate is connected to the upper plane of the bottom plate. The inner side edge of the bottom side reinforcing plate is fixedly connected to the inner surface of the U-shaped column. A cross baffle is arranged outside the lower section of the U-shaped column. The top end of the inner reinforcing rib is fixedly provided with a top reinforcing plate.

[0006] Further, the outer ends of the horizontal support rod and the inclined support rod are respectively and correspondingly connected to the inner side surfaces of the variable-diameter conical wall plate and the lower straight cylinder wall plate.

[0007] Further, the included angle between the inclined support rod and the horizontal support rod is 30 degrees.

[0008] Further, the model of the hydraulic jack is: SQD-350-100S.F type loose clamp type.

[0009] Further, the vertical support rod may be an H-shaped steel structure.

[0010] The utility model saves the materials for the reverse installation of the variable-diameter absorption tower, and can be reused after disassembly, greatly reducing the installation cost. It is simple to manufacture, convenient and safe to disassemble, and stable and reliable. It solves the problems such as the inability to disassemble the whole after the false cylinder is manufactured and installed, and at the same time completely solves the problem that the overall structure position of the hydraulic lifting device may be changed due to the variable diameter during installation, can greatly improve the operation efficiency, and effectively ensures the construction period and quality.

The outer ends of the horizontal support rod 4 and the inclined support rod 8 are connected to the variable-diameter conical wall plate 2 and the lower straight cylinder wall plate 3 in sections from top to bottom in sequence; the hydraulic lifting rod slider 9 inside the hydraulic jack 5 is connected to the bottom of the vertical support rod 6 at the lower end. The vertical support rod 6 is of a U-shaped column structure (as Figure 3 and Figure 4 shown). A top plate is arranged at its upper end, and a bottom plate 61 is arranged at its lower end. Inner reinforcing ribs 64 are fixedly arranged inside the U-shaped column on the upper surface of the bottom plate 61. A bottom side reinforcing plate 62 is fixedly arranged on one side at the lower end of the inner reinforcing rib 64. The bottom end of the bottom side reinforcing plate 62 is connected to the upper plane of the bottom plate 61. The inner side edge of the bottom side reinforcing plate 62 is fixedly connected to the inner surface of the U-shaped column. A cross baffle 63 is arranged outside the lower section of the U-shaped column. A top reinforcing plate 65 is fixedly arranged at the top end of the inner reinforcing rib 64.

[0017] Embodiment: A preferred embodiment of the present invention is introduced below. The absorption tower of a certain project is a variable-diameter tower. When installing the variable-diameter conical wall plate 2 (variable-diameter section cone) in the middle of the tower body, in the past, when using the hydraulic lifting device (hydraulic jack 5) of the upper tower body, the height of the variable-diameter section is 3.38 m, and the lifting height of the hydraulic lifting device (hydraulic jack 5) is 2.6 m, which cannot meet the requirement of lifting the height of two layers of variable-diameter cones. Then, the first layer of the conical wall plate of the variable-diameter conical wall plate 2 (variable-diameter section cone) is installed first, and then the process of lengthening the jacking support column is adopted to install the subsequent second layer of the conical wall plate and the lower wall plate.

[0018] In the present invention, when lifting the second layer of the conical wall plate of the variable-diameter section (variable-diameter conical wall plate 2) and the lower straight cylinder wall plate 3 section, an H-shaped steel (HN250*125) is used as the vertical support rod 6, and its upper end is fixedly welded to the upper straight cylinder wall plate 1 of the tower body, and the welding length is not less than 200 mm. The hydraulic jack 5 adopts an SQD-350-100S.F type loose clamp jack, and a hydraulic lifting rod slider 9 is arranged inside it. The bottom end of the vertical support rod 6 is placed on the hydraulic lifting rod slider 9. Horizontal support rods 4 are arranged at the middle part of the vertical support rod 6 and fixed to the variable-diameter conical wall plate 2 and the lower straight cylinder wall plate 3. Each is fixed to the inner walls of the variable-diameter conical wall plate 2 and the lower straight cylinder wall plate 3 by two horizontal support rods 4 (HM150*100). Each vertical support rod 6 is connected and fixed by a cross beam rod 7 (as Figure 2 shown). The cross beam rod 7 is made of angle steel (∠100×100×10).

[0019] During construction, when lifting, H-shaped steel (HN250*125) is used as the vertical support rod 6. Its upper end is welded and fixed at the intersection of the lower end of the upper straight cylinder wall plate 1 and the upper end of the variable-diameter conical wall plate 2, and the welding length is not less than 200 mm. The lower end is supported on the hydraulic lifting rod slider 9. A horizontal support rod 4 is arranged in the middle part of the vertical support rod 6 and fixed to the inner walls of the variable-diameter conical wall plate 2 and the lower straight cylinder wall plate 3. Two H-shaped steels (HM150*100) are used as the horizontal support rod 4 to fix each one to the tower body. Angle steel (∠100×100×10) is used as the cross beam rod 7 to connect and fix between each vertical support rod 6.

[0020] When the tower body is inverted to the variable-diameter section (see Figure 1 the variable-diameter conical wall plate 2 in the figure), a certain distance has been generated between the hydraulic lifting device (hydraulic jack 5) and the wall plate after the diameter change. The vertical support rod 6 is required to complete the inversion. The vertical support rod 6 is made of H-shaped steel. A support system (vertical support rod 6) needs to be set at the intersection of the upper straight cylinder wall plate 1 (upper straight section) and the lower straight cylinder wall plate 3 (transition section) of this variable-diameter transition section cone (i.e., the variable-diameter conical wall plate 2) for inversion. When installing the variable-diameter conical wall plate 2 in the middle of the tower body, the hydraulic lifting device (hydraulic jack 5) used for the upper tower body is adopted. First, install the first layer of conical wall plate (variable-diameter conical wall plate 2), and then adopt the process of lengthening the vertical support rod 6 to install the subsequent second layer of conical wall plate and the lower straight cylinder wall plate.

[0021] The vertical support rod 6 in the present utility model adopts a U-shaped column structure (as shown in Figure 3 and Figure 4 ). It is provided with a top plate at its upper end and a bottom plate 61 at its lower end. Inner strengthening ribs 64 are fixedly arranged in the U-shaped channel steel on the upper surface of the bottom plate 61. One side of the lower end of the inner strengthening ribs 64 is fixedly provided with a bottom side strengthening plate 62. The bottom end of the bottom side strengthening plate 62 is connected to the upper plane of the bottom plate 61. The inner side edge of the bottom side strengthening plate 62 is fixedly connected to the inner surface of the U-shaped channel steel. A cross baffle 63 is arranged outside the lower section of the H-shaped steel. A top strengthening plate 65 is fixedly arranged at the top end of the inner strengthening ribs 64. The bottom side strengthening plate 62, the cross baffle 63, the inner strengthening ribs 64 and the top strengthening plate 65 arranged on the vertical support rod 6 are all used to enhance its structural strength and ensure the safety and reliability of the construction facilities.
