The operators are in the hoisting area for a long time, and the operation efficiency is low. It is quite difficult to align all the bolts and the threaded holes of the anchor at the same time in a short period of time, which requires the operators to stay in the hoisting area for a long time, increasing the safety risk of the operation.

[0035] Large towers, such as distillation towers and absorption towers in the petrochemical industry, are important equipment for mass transfer and heat transfer between gas and liquid or liquid and liquid. They are usually composed of a cylinder, a head (or cover) and a support. The design and manufacture of towers must meet specific process requirements and are widely used in chemical, petrochemical and oil refining production. With the continuous expansion of the production capacity of petrochemical plants, the application of large towers in fields such as oil refining and coal chemical industry is increasing. In the petrochemical industry, tower equipment is becoming increasingly large and unconventional, which puts higher requirements on equipment installation. Large towers usually refer to towers with an inner diameter of ≥3600mm. Due to the high height and large diameter of large towers, there are more factors to consider, and the installation difficulty is much greater than that of ordinary towers.

[0036] The diameter and weight of tower equipment in the current integrated project are getting bigger and bigger, and the number of anchor bolts is also increasing, which brings many problems to the equipment installation. Affected by the crosswind, the time required to align the threaded holes on the tower with the anchor bolts is extended, and a large number of people are required to assist in positioning the equipment. The operators are in the hoisting area for a long time, and the operation efficiency is low. It is quite difficult to align all the bolts and the threaded holes of the anchor at the same time in a short period of time, which requires the operators to stay in the hoisting area for a long time, increasing the safety risk of the operation.

[0037] In order to solve the above technical problems, the present invention proposes a tower auxiliary installation device, which aims to provide a tower auxiliary installation device that consumes less manpower and is easier to position and install. Figures 1 to 4 The present invention provides a schematic structural diagram of an embodiment of a tower auxiliary installation device.

[0038] Please refer to Figures 1 to 4 The present invention proposes a tower auxiliary installation device 100, which is used for the installation of heavy towers, including multiple auxiliary rotating components 1, which are evenly spaced and arranged in a ring around the circumference of the tower. Each auxiliary rotating component 1 includes a roadbed box 11 and an electric hoist 12. The fixed end of the electric hoist 12 is arranged on the roadbed box 11, and the movable end of the electric hoist 12 is used to connect with the tower to drive the tower to rotate along the axial direction of the tower.

[0039] The tower installation device further includes an electric control component 2 , which is electrically connected to the multiple electric hoists 12 , and the electric control component 2 is used to synchronize the movements of the multiple electric hoists 12 .

[0040] The technical solution of the present invention proposes a tower auxiliary installation device 100 for installation of a heavy tower and a tower positioning and installation method for the tower auxiliary installation device 100. The tower auxiliary installation device 100 includes a plurality of auxiliary rotating components 1, which are evenly spaced and arranged in a ring around the circumference of the tower. The auxiliary rotating component 1 includes a roadbed box 11 and an electric hoist 12. The fixed end of the electric hoist 12 is arranged on the roadbed box 11, and the movable end of the electric hoist 12 is used to connect with the tower to drive the tower to rotate along the axial direction of the tower. The roadbed box 11 can serve as an anchor point of the electric hoist 12 due to its large mass and large contact area with the ground. The electric hoist 12 is gradually tightened by the electric control component 2 so that the tower moves and rotates in the radial direction, so that each threaded hole 220 at the bottom of the tower is aligned with a foundation bolt 310 of the tower base 300, thereby realizing auxiliary installation positioning. The tower auxiliary installation device 100 can greatly reduce the number of operators, improve the installation efficiency and reduce safety hazards.

[0041] It should be noted that in the actual construction process, adaptive adjustments can be made according to the weight and diameter of the tower. When the tower has a large size and a large mass, an electric hoist 12 is generally used for construction. The benefits of using an electric hoist 12 for auxiliary tower installation include improving work efficiency, reducing manpower requirements, and reducing operational safety risks. The electric hoist 12 is driven by electricity and can control the movement of heavy objects more quickly and accurately. Compared with a hand-pulled hoist, it reduces the need for manual operation, thereby reducing the labor intensity of the operator and shortening the operation time. In addition, the electric hoist 12 can be synchronously controlled by the electronic control component 2 to ensure that multiple hoists work in coordination, further improving the efficiency and safety of the installation process. These advantages of the electric hoist 12 make it very useful in the installation of heavy towers, especially when it is necessary to quickly and accurately align the threaded holes and the anchor bolts 310. The electric hoist 12 in the tower auxiliary installation device 100 can also be replaced by a hand chain hoist. When the hand chain hoist is used to replace the electric hoist 12, at least four staff members need to be arranged to be located at the 0°, 90°, 180° and 270° positions of the tower respectively, and the hand chain hoist is pulled by manpower to move the tower radially. In this way, since the hand chain hoist in each direction needs to be equipped with two staff members, compared with the electric hoist 12 driving method, although eight more labors are added, compared with the previous method of more than ten or even twenty manual auxiliary positioning, it can still achieve the effect of saving labor. The advantages of using a hand chain hoist for tower auxiliary installation include simple operation, convenient maintenance, high mechanical efficiency, small hand chain tension, excellent overall strength, and high transmission efficiency, especially in open-air and power-free working occasions. The hand chain hoist is small in size, light in weight, easy to carry and operate, and is particularly suitable for radial adjustment of medium-sized towers. At this time, the tower is in a suspended state, and only a small radial force needs to be applied to make the tower rotate around the central axis or move radially. In addition, the hand chain hoist is safe, reliable and easy to maintain. It shows its superiority in open-air and power-free working environments.

[0042] In addition, the number of auxiliary rotating components 1 can also be adaptively adjusted according to the size and quality of the tower. Four or more even-numbered auxiliary rotating components 1 can be set, so that it can be ensured that the opposite side of each auxiliary rotating component 1 has another auxiliary rotating component 1 that is balanced with it. The two oppositely arranged auxiliary rotating components 1 are retracted and released to ensure the smooth movement of the equipment. However, when arranging the auxiliary rotating components 1, it is necessary to ensure that the angles of each adjacent auxiliary rotating component 1 around the tower are equal, that is, they are evenly arranged. In one embodiment of the present invention, the tower auxiliary installation device 100 is provided with a total of four auxiliary rotating components 1. For details, please refer to Figure 1, four auxiliary rotating components 1 are arranged around the tower and spaced apart from the tower. The four auxiliary rotating components 1 are respectively located at 0°, 90°, 180° and 270° positions of the tower. When laying out the auxiliary rotating components 1, the roadbed box 11 should be laid out first, and the roadbed box 11 weighing several tons is lifted to the four positions of the tower by a lifting machinery. Then, an electric hoist 12 is installed on the side of the roadbed box 11 facing the tower. The electric hoist 12 is fixed with the roadbed box 11 as an anchor point, and the movable end of the electric hoist 12 is connected to the lifting lug around the tower. When the electric hoist 12 starts to pull the tower, the roadbed box 11 relies on the huge friction generated by its own weight to ensure that it does not move, so that the tower can be radially adjusted.

[0043] Based on the above embodiments, if an electric hoist 12 is used to pull the tower, it is necessary to ensure that every two relative electric hoists 12 work synchronously to ensure that the tower is installed correctly. In view of this, this solution respectively controls two groups of auxiliary rotating components 1 by setting a first electric control module 21 and a second electric control module 22. The first electric control module 21 connects the two electric hoists 12 at the 0° and 180° positions through a first control signal line 211, and the second electric control module 22 connects the two electric hoists at the 90° and 270° positions through a second control signal line 221, so as to achieve synchronous operation of the two auxiliary rotating components 1 of each group.

[0044] Since there are many anchor bolts 310 in a large tower, in order to align each anchor bolt 310 with the threaded hole 220 on the ring plate 210, the tower auxiliary installation device 100 further includes a guide member 3. For details, please refer to Figure 2 and Figure 3One end of the guide member 3 is tapered as a whole and has a guide cone surface 31, and the guide cone surface 31 is arranged facing the bottom of the tower. A mounting hole 32 is arranged at the bottom of the guide member 3. First, the guide member 3 is sleeved on the anchor bolt 310, and can be adaptively adjusted according to the actual diameter of the tower. In this embodiment, two anchor bolts 310 are spaced between every two adjacent guide members 3. The radial movement of the tower is adjusted by the electric hoist 12 so that the top of the guide cone surface 31 is exposed at the threaded hole 220. Then, the lifting machinery is controlled to lower the tower so that the guide inclined surface of the guide member 3 abuts against the inner wall of the threaded hole 220. Under the action of the gravity of the tower, the threaded hole 220 is immediately in the guide cone. The anchor bolt 310 is inserted under the guiding action of the surface 31. The diameter of the mounting hole 32 of the guide member 3 is slightly larger than the outer diameter of the anchor bolt 310, so that the guide member 3 can be easily mounted on the anchor bolt 310. The hole depth of the mounting hole 32 is between 120 mm and 150 mm. Specifically, it can be adjusted according to the specifications of the anchor bolt 310. After the tower pipeline is installed on the surface of some tower devices, the center of gravity of the equipment may change, which will cause the bottom surface of the ring plate 210 to be non-parallel to the surface of the tower base 300 after the equipment is lifted. In this way, guide members of different depths can adjust the distance between the top of the guide member and the bottom surface of the ring plate 210 to be consistent, thereby ensuring the stability of its installation.

[0045] The guide member 3 is generally made of metal. In this embodiment, a high-strength steel material is selected to improve its durability and enable it to be recycled for multiple uses. The guide member 3 can accurately align the anchor bolts 310 of the large tower with the threaded holes 220 on the ring plate 210, thereby improving installation efficiency and accuracy. Through the tapered guide surface and adaptive adjustment, the guide member 3 ensures the stability and safety of the tower during the hoisting process, reduces the adjustment time and labor intensity during the installation process, and avoids damage to the external threads of the anchor bolts 310 caused by improper alignment, thereby ensuring the long-term stable operation of the tower.

[0046] A circle of protective structure can also be set on the inner wall of the installation hole 32. Flexible materials such as silicone, rubber, etc. can be used as the protective structure. The flexible buffer layer is placed on the inner wall of the installation hole by bonding. In this way, after the guide member is installed, the inner wall of the installation hole of the guide member 3 can be prevented from contacting with the external thread of the anchor bolt 310 to cause scratches and damage to the thread. The buffer layer can effectively solve this problem. It should be noted that the process of installing the guide member 3 can be installed by automated equipment or manually. The present invention does not limit this. In one embodiment of the present invention, the guide member 3 is installed manually, and the number of guide members 3 can also be adjusted according to the actual size of the tower.

[0047] Based on the above-mentioned tower auxiliary installation device 100, the present invention also proposes a tower positioning and installation method applied to the above-mentioned tower auxiliary installation device, including the following steps: S1: determine the installation reference point with the center of the tower base 300 as the reference, and arrange the roadbed box 11 at the 0° position, 90° position, 180° position and 270° position of the installation reference point with the installation reference point as the center of the circle; S2: set an electric hoist 12 on the side of the roadbed box 11 facing the tower base 300 with the roadbed box 11 as the anchor point, and connect the movable end of the electric hoist 12 to the lifting ear of the tower circumference; S3: control each group of two relatively arranged electric hoists 12 to work synchronously, drive the tower to rotate so that the vertex of each guide cone surface 31 is exposed in the threaded hole 220 at the bottom of the tower; S4: control the lifting machinery to hook back so that the tower base is set on the tower base 300, and each anchor bolt 310 on the tower base 300 is penetrated through a threaded hole 220. It can be understood that in step S2, the movable end of the electric hoist 12 can be connected to the lifting ear on the circumference of the tower, or it can be directly connected to the threaded hole 220 on the tower ring plate 210, and the connection position is confirmed at the 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock directions of the tower, so as to ensure that the interval angle of each connection is the same.

[0048] Furthermore, in one embodiment, in order to ensure high-precision alignment of the tower and the tower base 300, this solution is equipped with four auxiliary positioners at the four electric hoist 12 positions, that is, the four positions of the tower, which can ensure the safety of equipment and personnel in response to special circumstances in some operations. When encountering a large crosswind, the module operator can make an emergency stop, which further improves the safety of the tower equipment hoisting operation. When constructing under the tower, since the tower is in an unstable state before it is successfully installed, it is easy to cause safety accidents. In order to further improve the safety of the operation, this solution controls the distance between the electric hoist 12 and the tower to 6m, and reasonably arranges the roadbed box 11 based on the 6m safety distance.

[0049] When the tower is successfully positioned, the guide member 3 on the anchor bolt 310 needs to be removed. This process is carried out by manual disassembly. After all the guide members 3 are removed, a nut needs to be installed on each anchor bolt 310. Usually, a wrench is used to tighten the nut to ensure that the nut is in close contact with the ring plate 210 at the bottom of the tower, thereby completing the fixing of the tower and ensuring the stability and safety of the tower during operation.

[0050] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
