Description

Technical Field

[0001] This invention relates to the field of building construction engineering, and in particular to an integrated device for multi-drive type steel column anti-fall installation and omnidirectional correction. Background Technology

[0002] In modern construction engineering, steel structures are widely used in industrial plants, high-rise buildings, bridges, and stadiums due to their advantages such as high strength, lightweight, excellent seismic performance, and short construction period. However, steel column installation, as a crucial step in steel structure construction, has high technical requirements, and the installation result directly affects the structural safety and durability. Traditional human-machine collaborative installation methods mainly rely on workers cooperating with lifting equipment for adjustment, which suffers from problems such as high labor intensity, low efficiency, and difficulty in guaranteeing positional accuracy, making it difficult to meet the high precision and high efficiency requirements of modern large-scale and complex steel structure projects. Therefore, installation accuracy and construction efficiency have become important technical indicators in current steel structure installation technology. To overcome these bottlenecks, various steel column installation and automatic correction devices have emerged.

[0003] The existing steel column installation, fixing, and correction devices have revealed a series of limitations in practical applications, mainly in the following aspects: First, the work tasks are relatively simple and limited, usually confined to a single function of installation, fixing, or correction, failing to achieve an organic combination between the two, resulting in a lack of continuity in the overall construction process; Second, the correction accuracy is relatively low, relying on manual calculation of the steel column coordinates for adjustment, which is easily affected by the subjective factors of workers and difficult to achieve high precision requirements; Third, safety hazards during construction are not fully considered, ignoring potential risks such as steel column falls, which may lead to safety accidents in engineering practice; Fourth, the devices are highly dependent on the working environment and lack versatility, being only applicable to specific steel column shapes, with adjustment dimensions limited to two dimensions, unable to meet three-dimensional correction and adjustment requirements, and having obvious applicability limitations; Fifth, the device structure and component design are too complex, making it difficult to achieve large-scale promotion and maintenance. The device design involves the coupling of multiple systems such as mechanics, electricity, and hydraulics, including sensors, electrical components, and hydraulic components in addition to mechanical parts, making system integration difficult and increasing manufacturing and maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the current steel column installation and fixing correction devices, and to provide a steel column anti-fall installation and omnidirectional correction device and method.

[0005] The objective of this invention can be achieved through the following technical solutions: As a first aspect of the present invention, a multi-drive type steel column installation and omnidirectional correction device is provided, including a device base with a hollow structure, wherein the hollow structure inside the device base is used to accommodate the steel column connecting plate, and is provided with a vertical correction adjustment unit and a horizontal correction adjustment unit. The vertical correction adjustment unit includes a pressure threaded plate, a pressure cam, a pressure wedge plate, a pressure rotating shaft, and a pressure screw. The pressure threaded plate is fixedly installed to the device base via the pressure rotating shaft. The pressure cam is arranged along the length of the device base; one side of the pressure cam is fixed to the pressure threaded plate by bolts to form a rotating pair, so that the pressure cam can swing relative to the pressure threaded plate; the cam shaft of the pressure cam abuts against the pressure wedge plate; the pressure screw is installed on the side of the pressure threaded plate opposite to the pressure cam by threaded connection, and passes through the pressure threaded plate to contact the other side of the pressure cam. The horizontal correction adjustment unit includes an adjusting nut, which is semi-fixed to the device base by a trapezoidal screw and a guide rod. The adjusting nut has a groove for clamping the steel column connecting plate on the side near the steel column installation working surface and moves along the length direction perpendicular to the device base. Rotary shaft bushings and adapters are installed at both ends of the trapezoidal screw for loading and fixing. After the device and the steel column are initially fixed, the pressure wedge is inserted between the pressure cam and the steel column connecting plate held by the adjusting nut.

[0006] As a preferred technical solution, an upper lifting ring is provided at one end of the device base near the horizontal correction and adjustment unit, and the upper lifting ring is detachably and movablely connected to the device base through a lifting shackle.

[0007] As a preferred technical solution, set screws are provided on both sides of the device base between the lifting shackle and the vertical correction adjustment unit, in a direction perpendicular to the steel column connecting plate.

[0008] As a preferred technical solution, the trapezoidal lead screw is mounted on the device base via a rotating shaft bushing, and conversion joints are installed at the ends of both sides of the trapezoidal lead screw; the guide rod is inserted into the through hole on the device base for installation. The adjusting nut has a threaded hole that matches the trapezoidal lead screw and a through hole that matches the guide rod; the adjusting nut is partially fixed to the device base via the trapezoidal lead screw and the guide rod.

[0009] As a preferred technical solution, an adjusting bolt is provided at the end of the device base near the horizontal correction and adjustment unit along the length direction of the device base. The adjusting bolt passes through the device base and is used to fix the steel column connecting plate located inside the device base.

[0010] As a second aspect of the present invention, a method for installing and correcting a multi-drive steel column is provided. The method employs one or more of the multi-drive steel column installation and omnidirectional correction devices described above to install and correct a steel column with connecting plates distributed around its perimeter. The steps are as follows: The steel column is installed and positioned using the steel column installation and omnidirectional correction device via a connecting plate; The steel column is horizontally adjusted using the device's horizontal adjustment unit. The vertical correction adjustment unit of the device is used to adjust the verticality of the steel column; After completing the positioning and adjustment, disassemble the steel column installation and omnidirectional correction device.

[0011] As a preferred technical solution, the installation and positioning of the steel column is specifically as follows: Hook the lifting lugs of the upper connecting plate of the steel column into the hollow position of the device base; install the lifting shackle into the lifting hole of the upper connecting plate, and connect the upper connecting plate to the device through the upper lifting ring and the lifting shackle; adjust the set screw to make the upper connecting plate centered and securely connected. The swing steel column installation and omnidirectional correction device is used to insert the lower connecting plate of the steel column into the groove of the adjusting nut of the horizontal correction adjustment unit; the pressure wedge is inserted between the pressure cam and the lower connecting plate; the adjusting nut is tightened to lock the lower connecting plate.

[0012] As a preferred technical solution, the vertical correction and adjustment process is as follows: by screwing in the pressure screw, the pressure screw presses the pressure cam to generate relative oscillation, and by changing the insertion depth and gap of the pressure wedge plate, the vertical direction adjustment of the upper steel column is achieved.

[0013] As a preferred technical solution, the horizontal correction and adjustment process is as follows: the adapter is turned clockwise / counterclockwise to make the trapezoidal lead screw rotate clockwise / counterclockwise, and then the adjusting nut is driven to move horizontally through the thread transmission; the adjusting nut drives the lower connecting plate held to move horizontally in the corresponding direction.

[0014] As a preferred technical solution, the disassembly of the steel column installation and omnidirectional correction device is specifically as follows: unscrew the set screws and adjusting screws on the upper and lower sides of the device base respectively, remove the lifting shackle from the lifting hole at the same time, remove the upper lifting ring, and remove the entire steel column installation and omnidirectional correction device from the lifting lug to complete the operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1) The present invention features a stable structure and high calibration accuracy. The device employs a lever principle in its design. In the vertical direction, the contact between the bolt and the cam converts the bolt's tightening into the cam's oscillation, which is then adjusted by inserting a pressure wedge plate to achieve stepless adjustment during the calibration process. In the horizontal direction, a lead screw is introduced in conjunction with a grooved adjusting nut for transmission. This provides self-locking performance while enabling higher precision calibration and fine-tuning, ensuring smooth movement. Furthermore, the symmetrical installation design allows for bidirectional input during calibration, effectively improving calibration accuracy.

[0016] 2) This invention offers strong safety during operation. The device incorporates a special anti-fall design. During operation, it is installed via the upper lifting ring, lifting shackle, and lifting holes at the lifting lugs on the device base and steel column. The upper set bolts further secure the device, ensuring it is firmly "hung" on the steel column. The adjusting bolts at the bottom "lock" the steel column in place, preventing it from tipping over and falling. These two mechanisms work together to significantly improve stability and safety during operation, greatly reducing the risk of falls. Therefore, this invention offers strong safety during operation.

[0017] 3) This invention enables omnidirectional fixed correction and exhibits strong adaptability to various working scenarios. The device achieves omnidirectional three-dimensional correction along the X, Y, and Z axes through horizontal and vertical adjustments and the coordinated operation of multiple devices installed on multiple mounting surfaces. Considering the adjustment offsets of multiple devices on multiple working surfaces and the comprehensive errors from welding of connecting plates, the design employs large tolerances or reserved clearances to ensure the coordinated operation of multiple devices and achieve omnidirectional correction and adjustment of steel columns of different specifications and shapes. Therefore, this invention achieves omnidirectional fixed correction while also demonstrating strong adaptability to different working scenarios. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solution of the present invention, providing detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0027] Example 1 This invention provides an integrated device for multi-drive steel column anti-fall installation and omnidirectional correction during construction, such as... Figure 1 As shown, it includes an upper lifting ring 1, a lifting shackle 2, a device base 15, a set screw 3, a vertical adjustment unit, a horizontal adjustment unit, and adjusting screws 8. The device base 15 is a hollow cubic frame. The upper lifting ring 1, lifting shackle 2, set screw 3, vertical adjustment unit, horizontal adjustment unit, and adjusting screws 8 are as follows: Figure 1 The components are installed collinearly from left to right within the device base 15. During operation, the device base 15 is mounted on the working surface, which in this embodiment is the surface on which the steel column is installed. The set screw 3 is responsible for fixing the upper connecting plate 16 horizontally, and the adjusting screw 8 is responsible for fixing the lower connecting plate 17 vertically.

[0028] like Figure 2 , 3 As shown in Figure 5, the vertical correction adjustment unit includes a pressure threaded plate 4, a pressure cam 5, a pressure wedge plate 12, a pressure shaft 13, and a pressure screw 14. The pressure threaded plate 4 and the pressure cam 5 are mounted on the device base 15 via the pressure shaft 13. The pressure threaded plate 4 and the pressure cam 5 are semi-fixed as a rotating pair. Bolts are used to connect the pressure cam 5 to the pressure threaded plate 4. The pressure screw 14 is installed on the pressure threaded plate 4 via a threaded connection. The pressure wedge plate 12 is clamped between the front pressure cam 5 and the rear adjusting nut 6 by the squeezing action of the front and rear pressure wedge plates 5.

[0029] like Figure 4 , 6As shown, the horizontal correction adjustment unit includes an adjusting nut 6, a trapezoidal lead screw 10, an adapter 7, a rotating shaft bushing 9, and a guide rod 11. The guide rod 11 is inserted into a through hole on the device base 15. The trapezoidal lead screw 10 is connected to the device base 15 via a threaded connection. The adjusting nut 6 is semi-fixed to the trapezoidal lead screw 10 via a threaded connection. The rotating shaft bushing 9 is threaded to the trapezoidal lead screw 10. The adapter 7 is installed on the trapezoidal lead screw 10. The adjusting nut 6 has a groove on the side near the working surface for clamping the steel column connecting plate.

[0030] In this embodiment, the upper lifting ring 1 and the lifting shackle 2 mainly provide fixing and installation functions; the device base 15 serves to accommodate functional components and provide support; the pressure screw 14 contacts the pressure cam 5 through the pressure threaded plate 4, and screwing in the pressure screw 14 causes the pressure cam 5 to swing relative to each other, causing the pressure wedge plate 12 to move up and down; the adjusting nut 6 slides left and right as the trapezoidal screw 10 is turned, driven by the screw. This embodiment can effectively improve and enhance the accuracy of alignment and correction of steel structure columns during construction projects.

[0031] In addition, in this embodiment, the required working load for horizontal correction adjustment is set to 15kN, the selected trapezoidal lead screw 10 has a tooth profile angle of 30° and a pitch P=3mm; the required working load for vertical correction adjustment is 50kN, and the M24 pressure screw 14 used has a nominal thread diameter d=24mm and a pitch P=3mm.

[0032] The working principle of this embodiment is as follows: At the beginning of the steel column installation, connecting plates are distributed around the steel column, with lifting holes for hoisting and transportation. After preliminary rough alignment, the initial installation and positioning of the steel column is carried out. The device proposed in this invention is "hung" on the lifting lug of the steel column through the hollow part of the device base 15. The upper connecting plate 16 of the steel column is connected to the device of this invention through the upper lifting ring 1 and the lifting shackle 2. The adjusting bolt 8 and the set screw 3 are tightened to further achieve a locking effect and prevent the steel column from falling during the operation. Then, ensure that the upper connecting plate 16 can be inserted into the upper part of the device base 15 in the center and that the lower connecting plate 17 can be inserted into the groove of the adjusting nut 6 without gaps. At this time, the initial installation and positioning of the steel column is completed.

[0033] After installation and positioning, horizontal correction and adjustment are performed. A screw-nut helical drive system is used, and power is manually input to the hexagonal input end of the adapter 7 mounted on the screw using a high-torque wrench. Precise adjustment of the nut's left and right displacement is achieved by controlling the forward and reverse screwing amount. Considering the complexity of the working conditions and space constraints in actual engineering, input connectors are symmetrically installed at both ends of the trapezoidal screw 10 along the device base 15. Both ends can be used as input ends for bidirectional input, allowing normal operation even when space is limited on one side. Initially, the horizontal offset is relatively large. During this initial correction phase, the screw is driven to move the adjusting nut 6 to the current offset position, causing the connecting plate to enter the nut slot. The horizontal correction is achieved by controlling the translation of the nut through the helical drive on both sides.

[0034] After horizontal correction and adjustment, vertical correction and adjustment are performed. High-precision stepless adjustment is achieved through the contact cooperation between bolts and cams, and cams and wedges. Utilizing the lever principle, the "bolt-cam" mechanism functions as a "jack." A high-torque wrench is used to manually tighten the pressure screw 14. The pressure screw 14 compresses the pressure cam 5, causing relative oscillation and lifting the upper connecting plate. The height of the cam's lifting is adjusted by regulating the insertion gap of the pressure wedge 12, thus converting the bolt's tightening amount into the vertical lifting and lowering of the steel column. Furthermore, considering the joint adjustment of multiple work surfaces and the welding errors in the connecting plates, the device employs large tolerances or pre-reserved clearance margins in both horizontal and vertical adjustable offsets.

[0035] The process of positioning correction and adjustment using the device proposed in this invention is as follows: Figure 7 As shown.

[0036] Figure 7 a) Installation and positioning stage of the device: a. The lifting lugs of the upper connecting plate 16 are attached to the hollow position of the device base 15; b. The upper connecting plate 16 and the device are connected by the upper lifting ring 1 and the lifting shackle 2; c. By adjusting and tightening the set screw 3 appropriately, the upper connecting plate 16 is centered and the connection is secure; d. The swing device is used to insert the lower connecting plate 17 into the groove of the adjusting nut 6 of the device's horizontal correction adjustment unit; e. The pressure wedge 12 is inserted and placed between the pressure cam 5 and the lower connecting plate 17; f. The adjusting nut 8 is tightened to ensure that the lower connecting plate 17 is locked.

[0037] Figure 7b is the process of vertical correction adjustment: a. Screw in the pressure screw 14; b. The pressure cam 5 swings relative to the pressure screw 14; c. Adjust the position of the pressure wedge plate 12 to achieve vertical adjustment of the upper steel column. The pressure screw 14, pressure cam 5, and upper connecting plate 16 form a lever. Therefore, by adjusting the insertion position of the pressure wedge plate, the vertical height of the upper connecting plate 16 lifted by the pressure cam 5 can be adjusted to achieve high-precision vertical correction adjustment.

[0038] Figure 7 c represents the horizontal correction and adjustment process: a. Turn the adapter 7 clockwise / counterclockwise to make the lead screw rotate clockwise / counterclockwise; b. The adjusting nut 6 moves horizontally through the threaded transmission; c. The lower connecting plate is clamped by the adjusting nut 6 and undergoes horizontal displacement in the corresponding direction.

[0039] Figure 7 d is the disassembly process of the device: a. Unscrew the set screw 3 above the device base 15; b. Unscrew the adjusting bolt 8 below the device base 15; c. Remove the lifting shackle 2 and the upper lifting ring 1, and at the same time remove the device from the steel column.

[0040] Example 2 As another embodiment of the present invention, the device of the present invention can not only be used alone, but also complete in-plane correction and adjustment in both horizontal and vertical directions. Alternatively, multiple devices can work together to extend the working dimension to the entire workspace. By installing the proposed device on the lifting lugs around the steel column according to the principle described in Example 1, and then adjusting and correcting the horizontal and vertical directions of the mounting surface of each device according to the principle described in Example 1, the three-dimensional adjustment and correction of the entire steel column in all directions can be completed.

[0041] After all the devices have been corrected, adjusted and fixed in the horizontal and vertical directions, and the required accuracy has been ensured, the set screws 3 and adjusting screws 8 on the upper and lower sides of the device base 15 are unscrewed respectively. The lifting shackle 2 is removed from the lifting hole and the upper lifting ring 1 is removed at the same time. Finally, the entire device is removed from the lifting lug to complete the operation.

[0042] Specifically, Figure 8 This is a schematic diagram illustrating the working process of multiple devices working together. Figure 8 'a' represents the installation process. Figure 8 b is a diagram illustrating the anti-tipping and anti-fall fastening measures. Figure 8 c is a schematic diagram of omnidirectional correction. Figure 8 The installation process for a involves installing multiple devices as shown in Example 1. Figure 8b represents a steel column that may fall and is at risk of tipping to one side. In this case, the adjusting bolt at the bottom of the device is tightened to lock it. This operation, together with the set screw 3 screwed in during installation, locks the upper and lower connecting plates respectively, fixing the freedom of the steel column to move up and down, thus providing a fall prevention function. Figure 8 Figure c shows the collaborative omnidirectional correction process. As shown in the figure, there are gaps in the horizontal and vertical directions between the steel columns. Omnidirectional correction and adjustment are achieved by screwing in the pressure screws 14 and adjusting nuts 6 of all devices.

[0043] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
