Description

Technical Field

[0001] The present invention relates to the technical field of installation auxiliary devices for special-shaped inclined column steel structures, in particular to an installation auxiliary device for special-shaped inclined column steel structures and a precision control process. Background Art

[0002] During the construction of steel structures, in addition to the conventional horizontal and vertical erection work, there are also a small number of special-shaped installation requirements such as inclined installation. The installation process of such special-shaped inclined installation requirements of steel columns is completed by crane hoisting and auxiliary installation equipment.

[0003] According to the existing Chinese patent CN205777600U, an auxiliary support device for installing an inclined column includes a support device respectively arranged on the upper part of the inclined column and a stabilizing device arranged on the lower part of the inclined column. The support device includes a clamp I that can be tightened on the inclined column, and a support column is provided below the clamp I. The top of the support column is hingedly connected to the clamp I, and the bottom of the support column can abut against the ground. The stabilizing device includes a clamp II that can be tightened on the inclined column, and a pull rope is provided on the left and right sides of the clamp II. One end of the pull rope is fixedly connected to the clamp II, and the other end of the pull rope can be fixedly connected to the ground. The utility model has a simple structure and is easy to use. During the installation process, the inclined column is no longer restricted by the support device, and the tilt angle can be adjusted, which shortens the construction period and improves construction efficiency.

[0004] According to the existing Chinese patent CN219060948U, a device for installing an inclined column of a steel structure includes a first support, a second support, a jack, and a supporting manipulator. The first support is provided with an inclined column rotating connector and a first wall connector, and the second support is provided with a second wall connector, which are arranged in sequence with the first support along the inclined direction of the inclined column from top to bottom. The jack is installed on the second support, and the supporting manipulator is installed on the jack. The device facilitates adjustment and calibration of the inclined direction and installation inclined angle position of the inclined column, is conducive to the implementation of the installation and construction of the inclined column of the steel structure, simplifies the construction process, facilitates installation and construction, improves construction efficiency, construction quality and construction safety, and reduces construction costs. It reduces the requirements for the construction operation surface of the inclined column installation and is suitable for the installation of steel structure inclined columns on existing concrete or masonry walls of prefabricated buildings such as steel structure factories, stadiums, and steel structure public buildings.

[0005] As for the auxiliary installation equipment for inclined columns provided in the above two comparative documents, the existing technologies all adopt similar technologies. An inclined installation position is formed by adjusting the installation device. The steel column is adjusted to the formed inclined installation position under the action of a crane and clamped and fixed with a clamp or the like, and then the fixing work is performed. However, it is well known that on the outer surface of the steel structure, in order to achieve the effect of corrosion and rust prevention, a protective layer will be applied on the steel structure. When clamping and fixing with a clamp, the protective layer is very easy to be damaged due to the hard contact between the external structure and the protective layer, thereby damaging the steel structure and increasing the probability of corrosion after installation. The traditional clamping work for the structure to be protected usually adopts the form of padding a rubber sheet at the clamping position. However, due to the elasticity of the rubber sheet, it will deform during the installation process of the inclined steel column, resulting in difficulty in controlling the installation position and insufficient accuracy. In addition, the overall weight of the steel column is large, and contact and extrusion and friction with the rubber gasket are still easy to damage the protective layer. Therefore, traditional passive protection will still damage the coating on the outer surface of the steel column.

[0006] Therefore, it is necessary to provide an installation auxiliary device and a precision control process for special-shaped inclined column steel structures to solve the above technical problems. Summary of the Invention

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figures 1 to 9 This embodiment provides a technical solution: an installation auxiliary device for a special-shaped inclined column steel structure, comprising a frame 1, two telescopic rod assemblies 2 being symmetrically fixed to the top of the frame 1, a bearing assembly 3 being rotatably mounted on the upper end of the telescopic rod assembly 2, a V-shaped recess being formed in the middle of the upper end of the bearing assembly 3, and the bearing assembly 3 being composed of a V-shaped plate 4 rotatably connected to the upper end of the telescopic rod assembly 2, an outer frame 9 fixed to the outer wall of the V-shaped plate 4, a clamping assembly 5 for clamping the inclined column arranged on the V-shaped plate 4, a first spray protection mechanism 6 installed on the clamping mechanism 5, and a second spray protection mechanism 7 arranged on the V-shaped plate 4, the first spray protection mechanism 6 and the second spray protection mechanism 7 automatically perform spray protection on the clamped part of the inclined column.

[0041] After the installation is completed, the clamping assembly 5 is released and the first spray protection mechanism 6 is driven to spray the clamping position of the steel column, so that the spray liquid covers the clamped position of the outer wall of the steel column, thereby achieving the protective effect. At the same time, when the telescopic rod assembly 2 is retracted and the bearing assembly 3 is separated from the steel column, the second spray protection mechanism 7 is driven to spray the protective liquid on the position where the steel column contacts the inner wall of the V-shaped plate 4.

[0042] The V-shaped plate 4 also includes a connecting plate 41 formed at a lower middle position thereof, a rotating shaft 42 fixed to the lower end of the connecting plate 41, and a first motor 43 fixed to the end of the rotating shaft 42. The first motor 43 is a reduction motor. The lower end of the connecting plate 41 extends through the outer frame 9 to the outside of the outer frame 9. The rotating shaft 42 is located on the outside of the outer frame 9. The rotating shaft 42 is rotatably connected to the upper end of the telescopic rod assembly 2 through a bearing. The first motor 43 is fixed to the outer wall of the telescopic rod assembly 2. When adjusting the angle of the load-bearing assembly 3, by driving the first motor 43 to rotate, the rotating shaft 42 is driven to rotate, thereby driving the connecting plate 41 to rotate, thereby adjusting the angle of the entire load-bearing assembly 3. In conjunction with adjusting the telescopic rod assembly 2 to the appropriate installation height, it is ensured that the entire installation auxiliary device can be adjusted to the required appropriate height and angle, so that the steel column is at the final required installation angle and height after being placed on the load-bearing assembly 3, achieving the effect of accurately controlling the installation angle and height. The telescopic rod assembly 2 is a prior art. Its specific structural principle has been disclosed in existing patents and actual products, so it will not be described in detail here.

[0043] The clamping assembly 5 includes a bidirectional screw 51, a clamping block 52 and a driving gear 55. The middle part of the upper end of the connecting plate 41 is rotatably connected to the bidirectional screw 51 through a bearing. The two ends of the bidirectional screw 51 are symmetrically threadedly connected to the clamping blocks 52 through threaded holes. The clamping block 52 is L-shaped, and the upper end of the clamping block 52 is slidably connected to the V-shaped plate 4 through a first sliding hole. The upper end of the clamping block 52 passes through the V-shaped plate 4 and extends to the inner side of the V-shaped plate 4. The end of the clamping block 52 located on the inner side of the V-shaped plate 4 is inclined. A driven gear 53 is fixed to one end of the bidirectional screw 51, and a second motor 54 is fixed to the upper end of the connecting plate 41. The second motor 54 is a reduction motor, and a driving gear 55 is fixed to the output end of the second motor 54. The driving gear 55 is meshed with the driven gear 53. When driving the clamp, the second motor 54 is driven to rotate, which drives the driving gear 55 to rotate and the driven gear 53 to rotate, thereby driving the bidirectional screw 51 to rotate, so that the two clamping blocks 52 on both sides slide in the direction of approaching each other. During the clamping process, the first spray protection mechanism 6 will be driven to perform the first protective liquid spraying work before clamping, so that the steel column can be pre-sprayed before being clamped, and then it is clamped and fixed. When releasing the clamp, the second motor 54 can be driven to rotate in the opposite direction, so that the two clamping blocks 52 are separated from each other, thereby releasing the clamping. At the same time, the first spray protection mechanism 6 performs the second spraying work, and the second spraying work is performed on the clamping position of the steel column.

[0044] The first spray protection mechanism 6 includes a first nozzle 61, a first liquid infusion pipe 62 and a second gear 611. The first nozzle 61 is fixed on the side where the two clamping blocks 52 are close to each other. The liquid inlet end of the first nozzle 61 is fixed with the first liquid infusion pipe 62, and the first liquid infusion pipe 62 is fixed to the clamping block 52. The first liquid infusion pipe 62 is a soft pipe. The two clamping blocks 52 are fixed on the side away from each other. A first discharge one-way valve 64 is fixed on the side wall of the lower end of the first storage tank 63. The end of the first liquid infusion pipe 62 is fixed to the liquid outlet end of the first discharge one-way valve 64. The inner side of the first storage tank 63 is slidably connected with a first slider 65. The protective liquid is stored in the space enclosed by the first slider 65 and the first storage tank 63. A first air inlet one-way valve 66 is fixed on the first slider 65, and a first Spring 67, the top of the first spring 67 is fixed to the inner wall of the first storage tank 63, the upper end of the first slider 65 is fixed with a push rod 68, the upper end of the push rod 68 is slidably connected to the first storage tank 63 through the second sliding hole, the top of the first storage tank 63 is rotatably connected to the transmission shaft 69 through a bearing, the middle part of the transmission shaft 69 is fixed with a cam 610, the top of the push rod 68 is in squeeze contact with the outer wall of the cam 610, and the two ends of the push rod 68 are symmetrically fixed with a second gear 611, and the two outer walls of the V-shaped plate 4 close to the second gear 611 are symmetrically fixed with racks 612, and the rack 612 is meshed with the second gear 611. A square sleeve 8 is also formed on the outer wall of the V-shaped plate 4, and the end of the rack 612 is fixed to the inner wall of the square sleeve 8. The square sleeve 8 improves the strength of the connection between the rack 612 and the outer wall of the V-shaped plate 4;

[0045] When the two clamping blocks 52 approach each other for clamping work, the clamping blocks 52 drive the transmission shaft 69 and the second gear 611 to move together. The second gear 611 is rotated by the rack 612 and drives the cam 610 to rotate. In the middle period when the two clamping blocks 52 approach each other, the cam 610 rotates 180 degrees to push the push rod 68 to slide downward, so that the first slider 65 slides downward in the first storage tank 63 and stretches the first spring 67. During this process, the first air inlet check valve 66 is closed, and the first discharge check valve 64 is opened. The material enters the first liquid infusion pipe 62 from the first storage tank 63 through the first discharge check valve 64 and is then sprayed from the first nozzle 61 to the outside of the steel column. When the wall is in the clamped position, after spraying is completed, the clamping block 52 continues to approach until it is clamped against the outer wall of the steel column, and then the rear section of the clamping block 52 approaches and clamps the gap, and the cam 610 continues to be rotated 180 degrees until the rear cam 610 completes a 360-degree rotation after clamping, and the first spring 67 resets in the latter period of time to stretch the first slider 65 to slide upward. During this process, the first discharge one-way valve 64 is closed, and the first air inlet one-way valve 66 is opened to draw outside air into the first storage tank 63. In the process of the two clamping blocks 52 releasing the clamping and moving away from each other, as described above, the spraying operation can be repeated, and the protective layer of the steel column whose clamping position is damaged can be further sprayed for protection.

[0046] Example 2

[0047] See also Figure 10 The remaining structures of this embodiment are the same as those of the first embodiment, except that the top of the push rod 68 is semicircular, which makes it easier for the cam 610 to push the push rod 68 when the cam 610 rotates, and makes it easier for the protruding part of the cam 610 to slide to the top of the push rod 68.

[0048] Example 3

[0049] See also Figures 1 to 9This embodiment provides a technical solution. The second spray protection mechanism 7 includes a second storage tank 71, a second slider 72, a push column 73 and a second nozzle 79. The second storage tank 71 is fixed to the outer wall of the connecting plate 41. The second slider 72 is slidably connected to the inner wall of the lower end of the second storage tank 71. The protection liquid is stored in the space surrounded by the second slider 72 and the second storage tank 71. A push column 73 is fixed on the top surface of the second slider 72. The push column 73 is slidably connected to the second storage tank 71 through a sliding seal. The push column 73 passes through the V-shaped plate 4 and extends to the inner side of the V-shaped plate 4. The outer side of the push column 73 is sleeved with a second spring 74. One end of the second spring 74 is fixed to the outer wall of the push column 73, and the other end of the second spring 74 is fixed to the outer wall of the second storage tank 71.

The third liquid infusion pipe 78 is a hard pipe. The upper end of the third liquid infusion pipe 78 extends to the inner side of the V-shaped plate 4 and is fixed with two second nozzles 79.

[0050] After the lifting of the second air inlet check valve 75, the air inlet check valve 75 is opened, and the air inlet check valve 75 is opened, so that the air in the second air inlet check valve 75 is opened, and the air in the second air inlet check valve 75 is opened.

[0054] S2. Determine the installation height and adjust the lengths of the two telescopic rod assemblies 2 so that the height of the bearing assembly 3 matches the installation height of the inclined column. At the same time, the lengths of the two telescopic rod assemblies 2 must be different according to the installation inclination angle of the inclined column to match the installation inclination angle of the inclined column.

[0055] S3. After adjusting the length of the telescopic rod assembly 2, adjust the angle of the bearing assembly so that the V-shaped recesses on the two bearing assemblies 3 correspond to each other and their inclination angles match the installation angle of the inclined column. After the height and angle adjustments are completed, assembly work is carried out.

[0056] The present application provides a first spray protection mechanism 6 and a second spray protection mechanism 7, which can spray the clamping part of the steel column with protective liquid during the installation process, so that the damaged coating of the steel column can be repaired, thereby ensuring the corrosion resistance of the steel column after installation, ensuring its service life, and reducing the impact of the installation on the service life of the steel column. Moreover, since the protection work of the spray liquid is mechanically linked to the installation work of the steel column, there is no need for separate control, which ensures the timeliness of the spraying and reduces the probability of spraying delay.
