Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary tooling for measuring steel structure installation. Background Technology

[0002] Measurement is a crucial step in steel structure installation. Traditional measurement methods often require two experienced surveyors, and the process is susceptible to external interference. For example, wind and temperature affect the spatial position and interaction forces of the columns, and varying tensions in the guy ropes lead to different stresses on the anchor bolts after installation, causing deflection when the guy ropes are loosened. Constant monitoring by the surveyors is labor-intensive, and inconsistencies in experience among personnel can introduce errors in the measurement and monitoring results, impacting the overall construction quality of the steel structure. Therefore, there is an urgent need in the market for an auxiliary tool that can automatically and in real-time monitor the positional changes of steel structural components to improve monitoring efficiency and reduce monitoring difficulty. Summary of the Invention

[0003] The present invention aims to solve the above problems, thereby providing a steel structure installation measurement auxiliary tooling that reduces the difficulty of inspection.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0005] A steel structure installation measurement auxiliary tooling includes a positioning frame, a guide mechanism symmetrically arranged on one side of the positioning frame, a drive mechanism connected to the guide mechanisms, a support mechanism connected to the guide mechanism, and an adjustable centering detection unit on the side of the positioning frame away from the guide mechanism.

[0006] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0007] When installing H-beam steel columns with pre-embedded steel plates in the base, two fixtures are prepared. One fixture is placed between the flanges of the column, and the drive mechanism moves the support mechanism along the guide mechanism towards the flange side. Then, the support mechanism supports the entire fixture on the column. The other fixture is installed between the two pre-embedded steel plates in the base as a reference point, and the installation principle is the same as for the column. Then, the position of the column is detected during the installation process by the centering detection unit. When erecting a crossbeam that is inclined opposite to the column, one fixture is installed on the column as a reference point, and the centering detection unit is moved to the standard angle. The other fixture is similarly installed on the crossbeam, and the position of the crossbeam is detected during the installation process by the centering detection unit. Improved monitoring accuracy and efficiency: Through the cooperation of two centering detection units, real-time monitoring of the steel structure installation process is realized, avoiding human error and significantly improving measurement accuracy. Automated monitoring reduces the need for surveyors, improves work efficiency, enhances fixture stability, and allows for flexible adjustment of the detection unit position according to the included angle between steel structural components, ensuring the applicability of measurement in various complex steel structure installation scenarios.

[0008] As a preferred embodiment, a further technical solution of the present invention is:

[0009] Furthermore, the guiding mechanism includes symmetrically opened guide slots on the positioning frame. The two guide slots are equipped with coaxial lead screws with opposite threads. The reverse thread design allows the two support mechanisms to move inward or outward simultaneously, improving adjustment efficiency and adapting to the spacing of H-shaped steel flanges of different sizes.

[0010] Furthermore, the drive mechanism includes a movable slot formed between the guide slots, a gearbox is installed in the movable slot, the lead screw has a smooth rod structure on the side near the gearbox and extends into the gearbox, a driven bevel gear is fitted 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 is movably passed through the gearbox, the driving shaft is perpendicular to the driven shaft and one end extends to the top of the positioning frame, the driving shaft and the driven shaft are connected by a worm gear, the worm gear transmission structure has a self-locking characteristic, which can prevent the lead screw from rotating in the opposite direction under load, ensuring that the support mechanism remains stable after positioning, the bevel gear set realizes the conversion of power direction, so that a single shaft input can drive the synchronous movement of the two lead screws, simplifying the operation process.

[0011] Furthermore, an adjustment knob is provided on the end of the drive shaft located outside the gearbox. The adjustment knob provides a manual operation interface, which makes it easy for construction personnel to precisely control the movement distance of the support mechanism and adapt to the needs of different installation precision.

[0012] Furthermore, the support mechanism includes connecting rods screwed to the lead screw, and two connecting rods are provided with first hydraulic cylinders with output ends facing away from the lead screw at their ends. The arrangement of the first hydraulic cylinders facing away from each other can form a symmetrical clamping force to ensure stable contact between the tooling and the steel structure.

[0013] Furthermore, it also includes an input hydraulic cylinder fixed on the positioning frame. The piston of the input hydraulic cylinder is provided with a threaded structure, and the cylinder body of the input hydraulic cylinder is provided with an internal threaded hole that mates with the piston. The rodless chamber of the input hydraulic cylinder is connected to the rodless chambers of the two first hydraulic cylinders through a flow divider and combiner valve. The flow divider and combiner valve ensures that the two hydraulic cylinders operate synchronously, avoiding the support mechanism from tilting due to uneven pressure. The threaded piston design allows the hydraulic pressure to be adjusted by rotating the input hydraulic cylinder, thereby achieving precise control of the support force.

[0014] Furthermore, a slide rod is movably inserted into the piston end of the first hydraulic cylinder. The inner end of the slide rod is equipped with a locking block, and the outer end of the slide rod is equipped with a magnetic sheet. The magnetic sheet can be quickly adsorbed onto the surface of the steel structure to achieve pre-fixation of the tooling, which facilitates subsequent mechanical locking operations. The locking block prevents the slide rod from disengaging from the piston.

[0015] Furthermore, a telescopic rod is installed on the central axis of one side of the positioning frame. First, the center line is drawn on the steel structure, and then the telescopic rod is used to support the center line to improve the accuracy of centering detection.

[0016] Furthermore, the side of the positioning frame away from the guide mechanism is arc-shaped with a groove along its edge. A slider is engaged and slidably connected to the groove, and a locking bolt is provided on the slider that abuts against the groove. The centering detection unit is located on the slider. The arc-shaped groove allows the centering detection unit to be adjusted at multiple angles to meet the measurement needs of beams with different tilt angles. The locking bolt adopts a friction anti-loosening design to ensure that the slider will not be displaced due to external force after adjustment.

[0017] Furthermore, the centering detection unit is a laser collimator or a target. The combination of the laser collimator and the target can realize non-contact measurement, reduce errors caused by human intervention, and can be switched to the reference end or the detection end as needed, improving the flexibility of use.

[0024] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0025] A steel structure installation measurement auxiliary tooling includes a positioning frame 1, a guide mechanism symmetrically arranged on one side of the positioning frame 1, a drive mechanism connected to the guide mechanisms, a support mechanism connected to the guide mechanism, and an adjustable centering detection unit 13 provided on the side of the positioning frame 1 away from the guide mechanism.

[0026] Furthermore, the guiding mechanism includes guide slots symmetrically opened on the positioning frame 1. The two guide slots are equipped with coaxial lead screws 2 with opposite threads. The reverse thread design allows the two support mechanisms to move inward or outward simultaneously, improving adjustment efficiency and adapting to the spacing of H-shaped steel flanges of different sizes.

[0027] Furthermore, the drive mechanism includes a movable slot formed between the guide slots, and a gearbox 3 is provided in the movable slot. The lead screw 2 has a smooth rod structure on the side near the gearbox 3 and extends into the gearbox 3. A driven bevel gear 4 is mounted on the end of the lead screw 2 located on one side of the gearbox 3. A driving bevel gear 5 meshes between the two driven bevel gears 4. A driven shaft connected to the driving bevel gear 5 is rotatably connected inside the gearbox 3. A driving shaft is movably passed 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 gear. The worm gear transmission structure has a self-locking characteristic, which can prevent the lead screw 2 from rotating in the opposite direction under load, ensuring that the support mechanism remains stable after positioning. The bevel gear set realizes the conversion of the power direction, so that a single shaft input can drive the two lead screws 2 to move synchronously, simplifying the operation process.

[0028] Furthermore, an adjustment knob 6 is provided on the end of the drive shaft located outside the gearbox 3. The adjustment knob 6 provides a manual operation interface, which makes it easy for construction personnel to precisely control the movement distance of the support mechanism and adapt to the needs of different installation precision.

[0029] Furthermore, the support mechanism includes connecting rods 7 screwed to lead screw 2. The connecting rods 7 are limited by both sides of the guide groove and move along the guide groove. The two connecting rods 7 are provided with first hydraulic cylinders 8 with opposite output ends on the ends away from lead screw 2. The opposite arrangement of the first hydraulic cylinders 8 can form a symmetrical clamping force to ensure stable contact between the tooling and the steel structure.

[0030] Furthermore, it also includes an input hydraulic cylinder 9 fixed on the positioning frame 1. 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 chamber of the input hydraulic cylinder 9 is connected to the rodless chambers of the two first hydraulic cylinders 8 through a flow divider and combiner valve. The piston cross section of the input hydraulic cylinder 9 is larger than that of the piston cross section of the first hydraulic cylinder 8. The flow divider and combiner valve ensures that the two hydraulic cylinders operate synchronously, avoiding the skew of the support mechanism due to uneven pressure. The threaded piston design allows the hydraulic pressure to be adjusted by rotating the input hydraulic cylinder 9, so as to achieve precise control of the support force.

[0031] Furthermore, a slide rod is movably inserted into the piston end of the first hydraulic cylinder 8. A locking 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 onto the surface of the steel structure to achieve pre-fixation of the tooling, which facilitates subsequent mechanical locking operations. The locking block prevents the slide rod from disengaging from the piston.

[0032] Furthermore, a telescopic rod 11 is provided on the central axis of one side of the positioning frame 1. The telescopic rod 11 is located on the same side as the guide mechanism. First, the center line is drawn on the steel structure, and then the telescopic rod 11 is used to press against the center line to improve the accuracy of centering detection.

[0033] Furthermore, the side of the positioning frame 1 away from the guide mechanism is arc-shaped and has a sliding groove along its edge. The sliding groove is T-shaped, and a slider 12 is snapped and slidably connected to it. A locking bolt is provided on the slider 12, which abuts against the sliding groove. The slider 12 also has a threaded hole that mates with the locking bolt. The locking bolt passes through the threaded hole and abuts against the sliding groove for limiting its position. The centering detection unit 13 is mounted on the slider 12. The arc-shaped sliding groove allows the centering detection unit 13 to be adjusted at multiple angles to meet the installation and measurement requirements of the crossbeam 15 with different tilt angles. The locking bolt adopts a friction anti-loosening design to ensure that the slider 12 will not be displaced due to external force after adjustment.

[0034] Furthermore, the centering detection unit 13 is a laser collimator or a target. The combination of the laser collimator and the target can realize non-contact measurement, reduce errors caused by human intervention, and can be switched to the reference end or the detection end as needed, improving the flexibility of use.

[0035] During the installation of the H-beam column 14, the reference fixture is first deployed by driving the support mechanism through the reverse threaded screw 2 in its symmetrically arranged guide mechanism. The hydraulic pressure is adjusted by the threaded piston of the input hydraulic cylinder 9, so that the first hydraulic cylinder 8, which is arranged opposite to each other, abuts against the pre-embedded steel plates of the base, and the slider 12 is fixed in the middle of the arc-shaped slide groove to form a reference point. Then, the inspection fixture is installed between the wing plates of the column 14, and the column 14 is positioned by pressing the telescopic rod 11 against the center line of the column 14. The operation of the adjustment knob 6 drives the bevel gear set through the worm gear transmission, so that the double screws 2 move synchronously and move the support mechanism towards the wing plate side. The magnetic plate 10 first drives the slide rod to be attracted to the surface of the wing plate to achieve pre-positioning. The hydraulic pressure is adjusted by the threaded piston of the input hydraulic cylinder 9. Pressure causes the first hydraulic cylinder 8, arranged in opposite directions, to abut against the wing plates of the column 14, fixing the slider 12 in the middle of the arc-shaped groove. The laser collimator and the target form a real-time monitoring system. After the column 14 is connected, multiple guy ropes restrict the swaying of the column 14. Then, the anchor bolts are installed. The spatial position of the column 14 and the base is monitored in real time by the collimator and the target to avoid the spatial position of the column 14 after the anchor bolts are installed due to different tensions of the guy ropes or strong winds on site. When installing the inclined beam 15, a working tool is installed on the column 14 as a reference point. The position of the slider 12 is adjusted to make the target angle aligned with the installation position of the beam 15. Another tool is installed on the beam 15 as a detection end.

[0036] The system employs a reverse-threaded lead screw 2 and a worm gear self-locking transmission mechanism, combined with a bevel gear set to achieve synchronous drive of the two lead screws 2. This ensures both the symmetry and stability of the support mechanism adjustment and adapts to the installation requirements of H-beams of different sizes. The hydraulic system ensures synchronous operation of the two cylinders through a flow divider and collector valve, and achieves precise control of the support force by combining the input hydraulic cylinder 9 with threaded adjustment, effectively solving the installation deviation problem caused by uneven tension of traditional guy ropes. The modularly designed centering detection unit 13 can flexibly switch between a laser collimator and a target, and with a multi-angle adjustable arc-shaped slide, it can adapt to the measurement needs of various installation scenarios such as columns 14 and beams 15. This tooling significantly reduces the reliance on professional surveyors during construction. By combining magnetic pre-fixation, telescopic rod 11 positioning, and optical precision measurement, it improves both measurement accuracy and work efficiency, providing reliable installation quality assurance for complex steel structure projects.
