[0002] The hoisting of building steel structures refers to the process of hoisting steel structure components from the ground or other places by hoisting equipment and installing them in the predetermined positions. It usually involves the use of tools such as cranes, slings, pulleys, etc. to ensure the precise positioning and safe installation of the components.

[0003] The Chinese patent application with the publication number CN117416865A discloses a steel structure hoisting device for building construction. It uses a pulley structure to connect with the steel structure and cooperates with devices such as a boom to adjust the steel structure at different angles such as front-back, left-right, up-down rotation, etc. And the adjustment of the angle is generally manually assisted for fine adjustment after hoisting onto the steel frame. During the fine adjustment process, the staff needs to work at high altitude, which is not only inconvenient for adjustment but also has a certain degree of danger. Therefore, further improvement is needed. Summary of the Invention

[0007] The light emitted by the upper indicating laser lamp is set as B1, the vertical line between the upper indicating laser lamp and the ground is set as B2, and the connection line between one end of B1 and B2 is set as B3.

[0008] The connection points on the steel frame are transferred to the ground in the form of light spots through the upper indicating laser lamp and the lower indicating laser lamp, enabling the alignment of the connection points of the steel structure on the ground.

The connection points on the steel frame are transferred to the ground in the form of light spots through the upper indicating laser lamp and the lower indicating laser lamp, enabling the alignment of the connection points of the steel structure on the ground.

[0025] The following will describe in detail the two embodiments of the present application with reference to the accompanying drawings.

[0026] The first embodiment:

[0027] Figures 1-5Disclosed is a hoisting device for the construction of a long-span steel structure building, including a base 1. A swivel base 2 is installed at the top end of the base 1. One end of the swivel base 2 is installed with a boom 3, and the boom 3 is used for hoisting steel structures. The top end of the base 1 is fixedly connected with an upper seat 4, and the upper seat 4 covers the outside of the swivel base 2. The top end of the upper seat 4 is fixedly connected with a cylinder 5. The center point of the cylinder 5 and the center point of the axis of the swivel base 2 are on the same straight line. Three mounting frames 501 are fixedly connected to the cylinder 5. An upper adjuster, a middle adjuster and a lower adjuster are respectively fixedly connected inside the three mounting frames 501. The upper adjuster, the middle adjuster and the lower adjuster all include a housing 6. A swivel motor 601 is fixedly connected to the inner wall of the housing 6. The output end of the swivel motor 601 is fixedly connected with a swing head 602. A rotating rod 603 is rotatably connected between the inner walls at both ends of the swing head 602. A vertical rotation motor 604 is fixedly connected to the outer wall at one end of the swing head 602. The output end of the vertical rotation motor 604 is fixedly connected with one end of the rotating rod 603. It also includes a distance sensor 7, an upper indicating laser lamp 8 and a lower indicating laser lamp 9. The distance sensor 7, the upper indicating laser lamp 8 and the lower indicating laser lamp 9 are respectively fixedly connected to the rotating rod 603 on the upper adjuster, the middle adjuster and the lower adjuster. It also includes a first calibration rod 11 and a second calibration rod 12.

[0028] When starting the upper adjuster and aligning the distance sensor 7 with the first calibration rod 11, the connection line between the distance sensor 7 and the first calibration rod 11 is set as A1, the vertical line of the first calibration rod 11 is set as A2, and the perpendicular line between the distance sensor 7 and A2 is set as A3. A right triangle is formed among A1, A2 and A3. Given the length of A1 and the included angle between A1 and A3, the length of A3 can be calculated.

[0029] The light ray emitted by the upper indicating laser lamp 8 is set as B1, the vertical line of the upper indicating laser lamp 8 is set as B2, and the perpendicular line adjacent to B2 is set as B3, and B3 is equal to A3. Given the lengths of B3 and B2, the length of B1 can be calculated, and then the included angle between B1 and B2 can be calculated. Adjust the irradiation angle of the upper indicating laser lamp 8 to make it equal to the included angle between B1 and B2. At this time, the connection point between B1 and B3 is set as C1.

[0030] Similarly, when the distance sensor 7 is aligned with the second calibration rod 12, C2 can be calculated.

[0031] The connection points of the steel structure are set to two. After obtaining C1 and C2, align the two connection points of the steel structure with C1 and C2 respectively.

[0032] Before hoisting, the first calibration rod 11 and the second calibration rod 12 need to be fixed on the steel frame, and the first calibration rod 11 and the second calibration rod 12 are perpendicular to the ground.

[0033] Through the above settings, the vertical line from C1 to the axis of rotation of the turntable 2 is equal to the vertical line from the first base point to the axis of rotation of the turntable 2, and the vertical line from C2 to the axis of rotation of the turntable 2 is equal to the vertical line from the first base point to the axis of rotation of the turntable 2. In this way, when the lifting arm 3 hoists the steel structure, only the lifting and rotating actions of the steel structure need to be completed, and the steel structure can be hoisted onto the steel frame without the assistance of other devices, improving the hoisting accuracy.

[0034] The connection points on the steel frame are transferred to the ground in the form of light points through the upper indicating laser lamp 8 and the lower indicating laser lamp 9, enabling the alignment of the connection points of the steel structure on the ground. Compared with the adjustment operation on the steel frame, it not only improves the convenience of adjustment but also enhances the safety of the staff.

[0035] When the upper regulator, the middle regulator, and the lower regulator are working, when the slewing motor 601 starts, it can drive the swing head 602 to rotate along the horizontal direction. When the luffing motor 604 starts, it can drive the rotating rod 603 to rotate along the vertical direction, and then it can control the distance sensor 7, the upper indicating laser lamp 8, and the lower indicating laser lamp 9 to rotate at different angles.

[0036] The second embodiment:

[0037] Figure 1 and Figures 3-6 A hoisting device for the construction of a large-span steel structure building is shown. Different from the first embodiment, when the upper indicating laser lamp 8 and the lower indicating laser lamp 9 rotate, the emitted light rays can form an aperture, which are respectively set as C11 and C21. When the upper indicating laser lamp 8 and the lower indicating laser lamp 9 rotate, the slewing motor 601 is started to drive the upper indicating laser lamp 8 and the lower indicating laser lamp 9 to rotate at high speed, and any point of C11 and C21 can be aligned with the two connection points of the steel structure. Through the above settings, the convenience of aligning the connection points of the steel structure can be further increased, and the construction difficulty can be reduced.

[0038] The laser lights emitted by the upper indicating laser lamp 8 and the lower indicating laser lamp 9 have opposite colors, and a plurality of upper indicating laser lamps 8 and lower indicating laser lamps 9 are provided in total. Through the above settings, the two connection points of the steel structure can be distinguished by the different colors of the upper indicating laser lamp 8 and the lower indicating laser lamp 9, avoiding the situation where the connection points of the steel structure are opposite.

[0039] The vertical line of the connection point of the steel structure is set as D1, and the connection line between the upper indicating laser lamp 8 and the top of D1 is set as F1. Given the lengths of D1 and B1 and the included angle between D1 and B1, the included angle G1 between F1 and B1 can be calculated, and then the upper indicating laser lamp 8 is driven to rotate by G1. At this time, B1 coincides with F1.

[0040] The connection points of the steel structure are usually not flush with the ground, which causes the C1 irradiated on the connection points of the steel structure to be elevated, resulting in a certain error. Through the above settings, the light emitted by the upper indicating laser lamp 8 can be automatically calibrated according to the height of the connection points of the steel structure, so that the light emitted by the upper indicating laser lamp 8 irradiates on the connection points of the steel structure, further improving the convenience of positioning the connection points of the steel structure.

[0041] Similarly, the irradiation position of the lower indicating laser lamp 9 can be calculated and adjusted.

[0042] The upper regulator, middle regulator and lower regulator further include gyro sensors for obtaining the rotation angle of the rotating rod 603. The middle regulator and lower regulator further include height sensors for obtaining the vertical height of the rotating rod 603 from the ground. A lidar sensor is also fixedly connected to the top end of the cylinder 5 for positioning the first calibration rod 11 and the second calibration rod 12.

[0043] After the lidar sensor positions the first calibration rod 11 and the second calibration rod 12, the pitch angle and azimuth angle of the distance sensor 7 are calculated to provide a rotation angle for the distance sensor 7 to align with the first calibration rod 11 and the second calibration rod 12.

[0044] It further includes two laser receivers 13. A lifting rod 10 is fixedly connected between the upper seat 4 and the cylinder 5, and the output end of the lifting rod 10 is fixedly connected to the bottom end of the cylinder 5.

[0045] After the position of the steel structure is determined, the two laser receivers 13 can be respectively installed on two fixed points of the steel structure. At this time, when the upper indicating laser lamp 8 and the lower indicating laser lamp 9 irradiate on the laser receivers 13, during the hoisting process of the steel structure, the steel structure gradually rises. At this time, the lifting rod 10 is started to drive the cylinder 5 to rise synchronously. When the steel structure rotates, the upper indicating laser lamp 8 and the lower indicating laser lamp 9 rotate synchronously, so that the upper indicating laser lamp 8 and the lower indicating laser lamp 9 always irradiate on the lifting rod 10. If the lifting rod 10 does not receive the laser signal, it indicates that the connection point is offset, and adjustments can be made in time, so that the connection points of the steel structure can be monitored during the hoisting process of the steel structure, and the accuracy of the hoisting of the steel structure can be improved again.

[0046] Combined with the current actual requirements, the above implementation manner adopted by this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
