Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to an auxiliary tooling for steel structure installation measurement. Background Art

[0002] During the installation of steel structures, measurement is one of the key links. Traditional measurement methods often require the cooperation of two experienced surveyors, and the measurement process is easily interfered by external factors. For example, wind force and temperature affect the spatial position and mutual acting force of columns. Different tensions of each guy wire result in different stresses of each bolt after the anchor bolts are installed. After loosening the guy wires to form deflection, the surveyors need to monitor constantly, which consumes a lot of labor. Moreover, due to different experiences of different personnel, the measurement and monitoring results have errors, affecting the overall construction quality of steel structure buildings. Therefore, there is an urgent need in the market for an auxiliary tooling that can automatically and real-time monitor the position changes of steel structure components to improve the monitoring efficiency and reduce the monitoring difficulty. Summary of the Invention

[0003] The present invention aims to solve the above problems, and thus provides an auxiliary tooling for steel structure installation measurement that reduces the detection difficulty.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: An auxiliary tooling for steel structure installation measurement includes a positioning frame. On one side of the positioning frame, guiding mechanisms are symmetrically arranged. A driving mechanism is commonly connected between the guiding mechanisms. A supporting mechanism is connected to the guiding mechanisms. On the side of the positioning frame away from the guiding mechanisms, a centering detection unit with adjustable position is provided.

[0005] The present invention adopting the above technical solution, compared with the prior art, has the following prominent features: When installing the H-shaped steel column and the steel plate embedded in the foundation, prepare two toolings. Place one tooling between the flange plates of the column. The driving mechanism drives the supporting mechanism to move along the guiding mechanism towards the flange plate side, and then the supporting mechanism supports the whole tooling on the column. Install the other tooling between the two steel plates embedded in the foundation as a reference point. The installation principle is the same as that of the column. Then, detect the position during the installation of the column through the centering detection unit. When erecting the cross beam inclined relative to the column, install one tooling on the column as a reference point and move the centering detection unit to the standard angle. Install the other tooling on the cross beam in the same way. Then, detect the position during the installation of the cross beam through the centering detection unit; improve the monitoring accuracy and efficiency: through the cooperation of the two centering detection units, real-time monitoring during the steel structure installation process is achieved, avoiding human operation errors and significantly improving the measurement accuracy; automated monitoring reduces the need for surveyors and improves work efficiency; enhance the stability of the tooling, and the position of the detection unit can be flexibly adjusted according to the included angle between steel structure components, ensuring the applicability of measurement in various complex steel structure installation scenarios.

[0006] Preferably, a further technical solution of the present invention is as follows: Furthermore, the guiding mechanism includes guiding grooves symmetrically formed on the positioning frame. Two guiding grooves are provided with coaxial lead screws with opposite threads. The reverse thread design enables the two side support mechanisms to move inward or outward simultaneously, improving the adjustment efficiency and adapting to the H-beam flange spacing of different sizes.

[0007] Furthermore, the driving mechanism includes a movable groove formed between the guiding grooves. A gearbox is arranged in the movable groove. One side of the lead screw close to the gearbox is a smooth rod structure and extends into the gearbox. A driven bevel gear is sleeved on the end of the lead screw on one side of the gearbox. A driving bevel gear meshes between the two driven bevel gears. A driven shaft connected to the driving bevel gear is rotatably connected in the gearbox. A driving shaft movably penetrates through the gearbox. The driving shaft is perpendicular to the driven shaft and one end extends above the positioning frame. The driving shaft and the driven shaft are connected by a worm and worm gear. The worm and worm gear transmission structure has a self-locking characteristic, which can prevent the lead screw from rotating reversely under the action of load, ensuring the stability of the support mechanism after positioning. The bevel gear set realizes the conversion of the power direction, enabling single-axis input to drive the double lead screws to move synchronously and simplifying the operation process.

[0008] Furthermore, an adjustment knob is provided on the end of the driving shaft outside the gearbox. The adjustment knob provides a manual operation interface, facilitating the construction personnel to precisely control the moving distance of the support mechanism and adapting to the requirements of different installation precisions.

[0009] Furthermore, the support mechanism includes a connecting rod screwed to the lead screw. At the ends of the two connecting rods away from the lead screw, first hydraulic cylinders with opposite output ends are arranged. The arrangement of the first hydraulic cylinders with opposite directions can form a symmetrical clamping force, ensuring stable contact between the tooling and the steel structure.

[0010] Furthermore, it further includes an input hydraulic cylinder fixed on the positioning frame. A threaded structure is provided on the piston of the input hydraulic cylinder. An internal threaded hole matching the piston is provided on the cylinder body of the input hydraulic cylinder. The rodless cavity of the input hydraulic cylinder is connected to the rodless cavities of the two first hydraulic cylinders through a flow dividing and collecting valve. The flow dividing and collecting valve ensures the synchronous action of the two hydraulic cylinders, avoiding the deviation of the support mechanism caused by uneven pressure. The piston design with threaded fit allows the adjustment of the hydraulic pressure by rotating the input hydraulic cylinder, realizing the precise control of the supporting force.

[0011] Furthermore, a sliding rod is movably inserted into the end of the piston of the first hydraulic cylinder. A clamping block is provided at the inner end of the sliding rod, and a magnetic sheet is provided at the outer end of the sliding rod. The magnetic sheet can be quickly adsorbed on the surface of the steel structure to realize the pre-fixation of the tooling, facilitating the subsequent mechanical locking operation. The clamping block prevents the sliding rod from detaching from the piston.

[0012] Furthermore, a telescopic rod is provided on the central axis on one side of the positioning frame. First, draw the center line on the steel structure and use the telescopic rod to top against the center line to improve the accuracy of centering detection.

[0013] Furthermore, the side of the positioning frame away from the guiding mechanism is arc-shaped and a sliding groove is provided on the edge. A slider is clamped and slidably connected on the sliding groove, and a locking bolt that abuts against the sliding groove is arranged on the slider. The centering detection unit is arranged on the slider. The arc-shaped sliding groove allows the centering detection unit to be adjusted at multiple angles to adapt to the measurement requirements for installing beams with different inclination angles. The locking bolt adopts a friction anti-loosening design to ensure that the slider will not be displaced due to external forces after adjustment.

[0014] Furthermore, the centering detection unit is a laser collimator or a target. The cooperation of the laser collimator and the target can achieve non-contact measurement, reduce the errors caused by human intervention, and can be switched to the reference end or the detection end according to needs, improving the flexibility of use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further illustrates the present invention with reference to embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0017] An auxiliary tooling for steel structure installation measurement includes a positioning frame 1. Guiding mechanisms are symmetrically arranged on one side of the positioning frame 1. A driving mechanism is commonly connected between the guiding mechanisms. A supporting mechanism is connected to the guiding mechanisms. A centering detection unit 13 with adjustable position is arranged on the side of the positioning frame 1 away from the guiding mechanism.

[0018] Furthermore, the guiding mechanism includes guiding grooves symmetrically formed on the positioning frame 1. Two guiding grooves are provided with lead screws 2 that are coaxial and have opposite threads. The reverse thread design enables the two side support mechanisms to move inward or outward simultaneously, improving the adjustment efficiency and adapting to the spacing between the flanges of H-shaped steel with different sizes.

[0019] Furthermore, the driving mechanism includes a movable groove formed between the guiding grooves. A gearbox 3 is provided in the movable groove. One side of the lead screw 2 close to the gearbox 3 is a smooth rod structure and extends into the gearbox 3. A driven bevel gear 4 is sleeved on the end of the lead screw 2 on one side of the gearbox 3. A driving bevel gear 5 is meshed between the two driven bevel gears 4. A driven shaft connected to the driving bevel gear 5 is rotatably connected in the gearbox 3. A driving shaft movably penetrates through the gearbox 3. The driving shaft is perpendicular to the driven shaft and one end extends above the positioning frame 1. The driving shaft and the driven shaft are connected by a worm and worm gear. The worm and worm gear transmission structure has a self-locking characteristic, which can prevent the lead screw 2 from rotating reversely under the action of load, ensuring the stability of the support mechanism after positioning. The bevel gear set realizes the conversion of the power direction, enabling single-axis input to drive the two lead screws 2 to move synchronously, simplifying the operation process.

[0020] Furthermore, an adjustment knob 6 is provided on the end of the driving shaft outside the gearbox 3. The adjustment knob 6 provides a manual operation interface, facilitating the construction personnel to precisely control the moving distance of the support mechanism and adapting to the requirements of different installation precisions.

[0021] Furthermore, the support mechanism includes a connecting rod 7 screwed to the lead screw 2. The connecting rod 7 is limited by both sides of the guiding groove and thus moves along the guiding groove. At the ends of the two connecting rods 7 away from the lead screw 2, first hydraulic cylinders 8 with opposite output ends are provided. The arrangement of the first hydraulic cylinders 8 with opposite directions can form a symmetric clamping force, ensuring stable contact between the tooling and the steel structure.

[0022] Furthermore, an input hydraulic cylinder 9 fixed on the positioning frame 1 is also included. The piston of the input hydraulic cylinder 9 is provided with a threaded structure, and the cylinder body of the input hydraulic cylinder 9 is provided with an internal threaded hole that cooperates with the piston. The rodless cavity of the input hydraulic cylinder 9 is connected to the rodless cavities of the two first hydraulic cylinders 8 through a flow dividing and collecting valve. The piston cross-section of the input hydraulic cylinder 9 is larger than that of the first hydraulic cylinder 8. The flow dividing and collecting valve ensures the synchronous action of the two hydraulic cylinders, avoiding the deviation of the support mechanism caused by uneven pressure. The piston design with threaded cooperation allows the hydraulic pressure to be adjusted by rotating the input hydraulic cylinder 9, realizing precise control of the supporting force.

[0023] Furthermore, a slide rod is movably inserted at the end of the piston of the first hydraulic cylinder 8. A clamping block is provided at the inner end of the slide rod, and a magnetic sheet 10 is provided at the outer end of the slide rod. The magnetic sheet 10 can be quickly adsorbed on the surface of the steel structure to realize the pre-fixation of the tooling, facilitating subsequent mechanical locking operations. The clamping block prevents the slide rod from detaching from the piston.

[0024] Further, a telescopic rod 11 is provided on the central axis of one side of the positioning frame 1. The telescopic rod 11 and the guiding mechanism are on the same side. First, draw the center line on the steel structure, and use the telescopic rod 11 to top against the center line to improve the accuracy of centering detection.

[0025] Further, the side of the positioning frame 1 away from the guiding mechanism is arc-shaped and a chute is provided on the edge. The chute is T-shaped. A slider 12 is clamped and slidably connected to the chute. A locking bolt that abuts against the chute is provided on the slider 12. A threaded hole that cooperates with the locking bolt is provided on the slider 12. The locking bolt passes through the threaded hole and abuts against the chute for limiting. The centering detection unit 13 is arranged on the slider 12. The arc-shaped chute allows the centering detection unit 13 to be adjusted at multiple angles to adapt to the installation and measurement requirements of the cross beam 15 at different inclination angles. The locking bolt adopts a friction anti-loosening design to ensure that the slider 12 will not be displaced due to external forces after adjustment.

[0026] Further, the centering detection unit 13 is a laser collimator or a target. The cooperation of the laser collimator and the target can realize non-contact measurement, reduce the errors caused by human intervention, and can be switched to the reference end or the detection end according to needs, improving the flexibility of use.

[0027] When installing the H-shaped steel column 14, first drive the support mechanism to expand through the reverse threaded lead screw 2 in the symmetrically arranged guiding mechanism of the reference tooling. Adjust the hydraulic pressure through the threaded piston of the hydraulic cylinder 9 so that the oppositely arranged first hydraulic cylinders 8 abut between the base embedded steel plates, and fix the slider 12 in the middle of the arc-shaped chute to form a reference point; then install the detection tooling between the flanges of the column 14, and position it by pressing the telescopic rod 11 against the center line of the column 14. Operate the adjustment knob 6 to drive the bevel gear set through the worm and worm drive, so that the double lead screw 2 moves synchronously to move the support mechanism towards the flange side. The magnetic sheet 10 preferentially drives the slide bar to adsorb on the surface of the flange to achieve pre-positioning. Adjust the hydraulic pressure through the threaded piston of the hydraulic cylinder 9 so that the oppositely arranged first hydraulic cylinders 8 abut between the flanges of the column 14, and fix the slider 12 in the middle of the arc-shaped chute. The laser collimator and the target form a real-time monitoring system. After the column 14 is docked, limit the sway of the column 14 through multiple guy ropes. Then install the anchor bolts, and monitor the spatial position of the column 14 and the base in real time through the cooperation of the collimator and the target to avoid the spatial position of the column 14 after the installation of the anchor bolts being affected by factors such as different tensions of each guy rope or strong winds on site; when installing the inclined cross beam 15, install a tooling on the column 14 as a reference point, adjust the position of the slider 12 to align the angle of the target with the installation position of the cross beam 15, and install another tooling on the cross beam 15 as the detection end.

[0028] The reverse-threaded lead screw 2 and the worm and worm gear self-locking transmission mechanism are adopted, and the bevel gear set is used to realize the synchronous drive of the double lead screws 2, which not only ensures the symmetry and stability of the adjustment of the support mechanism, but also can meet the installation requirements of H-shaped steel of different sizes; the hydraulic system ensures the synchronous action of the double cylinders through the flow dividing and collecting valve, and combines with the input hydraulic cylinder 9 with thread adjustment to realize the precise control of the support force, effectively solving the installation deviation problem caused by uneven tension of the traditional guy ropes; the modularized centering detection unit 13 can be flexibly switched between the laser collimator and the target, and in cooperation with the arc-shaped sliding groove that can be adjusted at multiple angles, it can meet the measurement requirements of various installation scenarios such as the column 14 and the cross beam 15. This tooling significantly reduces the dependence on professional surveyors during construction. By combining magnetic pre-fixation, positioning of the telescopic rod 11 and optical precise measurement, it improves the measurement accuracy while enhancing the work efficiency, providing reliable installation quality guarantee for complex steel structure projects.
