Description

Technical Field

[0001] This invention relates to the field of steel component technology, specifically a positioning device for assembling steel structure components. Background Technology

[0002] Steel components refer to composite steel structural members that can bear and transmit loads, made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams cold-bent or welded and connected by connectors. Steel components are widely used, and steel structure factory buildings mainly refer to factory buildings whose main load-bearing components are made of steel, including steel columns, steel beams, steel structural foundations, steel roof trusses, and steel roofs.

[0003] However, steel structure workshops are prone to quality problems such as loosening of component connections during construction, mainly due to insufficient strength in handling special and important processes. Special processes include welding and painting, while important processes include material cutting and assembly. Among these, welding is a concealed project and one of the processes most prone to quality problems. Defects in welds can be classified as slag inclusions, incomplete fusion, and porosity. The connection structure between the roof panel and the ridge of existing steel structure workshops has a certain slope. If the connection strength of the weld cannot be guaranteed, the compressive strength of the roof panel will be weakened. Based on this, the present invention designs a positioning device for assembling steel structure components to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning device for assembling steel structure components, so as to solve the problem mentioned above that the connection strength and welding quality of the roof panels and ridges of existing steel structure workshops need to be improved.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning device for assembling steel structure components includes a movable support assembly for supporting and moving the positioning device. The movable support assembly has a rechargeable power supply installed inside. A vertical height adjustment assembly is connected to the top of the movable support assembly to adjust the overall vertical height of the positioning device, thereby adapting the vertical height adjustment assembly to the installation height of the factory roof panel. A roof panel end-clamping assembly is connected to the top of the vertical height adjustment assembly via a positioning block. This assembly is used to install and position the roof panel at an angle along the roof's inclined surface, facilitating the clamping and positioning of the roof panel to be welded at its welding position on the factory roof ridge. This facilitates alignment of the weld between the roof panel and the ridge, improving both the ease of welding between the roof panel and the ridge and enhancing the weld quality. The roof panel end-clamping assembly includes a limiting groove and an adjusting cylinder connected within the limiting groove via a wedge-shaped seat. The set consists of an adjusting cylinder assembly. The top of the adjusting cylinder assembly is connected to a retaining rod via a cylinder telescopic rod. Both ends of the retaining rod pass through a limiting frame. The lower end of the limiting frame is connected to a limiting groove bearing via a round rod. The adjusting cylinder assembly adjusts the rotation angle of the limiting frame around the round rod via the cylinder telescopic rod, thereby adjusting the tilt angle of the top surface of the connecting rod. When the limiting frame rotates in the vertical direction, the retaining rod slides inside the limiting frame. The limiting frame limits the movement distance of the retaining rod. The top of the limiting frame is connected to a snap-fit ​​plate via a connecting rod bolt. One end of the snap-fit ​​plate is equipped with an alignment component, which is used to align the welding positions of the roof panel and the ridge, improving the welding accuracy at the weld between the roof panel and the ridge. By strengthening the contact area between the roof panel and the ridge and reducing the distance between them through the alignment component, slag inclusions, incomplete fusion, and porosity defects at the weld can be reduced.The roof panel bottom support assembly includes a drive motor mounted on the side of the limiting groove. The input end of the drive motor is electrically connected to an external power source. When the drive motor is started, it drives a driven wheel through its output end, which meshes with a driven wheel. A driven shaft passes through the inside of the driven wheel. A limiting rod is fixed to the inner wall of the limiting groove. A movable seat is connected to the surfaces of the driven shaft and the limiting rod. The top of the movable seat is connected to a suction cup assembly via a force-applying hydraulic cylinder and an adjusting hydraulic cylinder. In use, the roof panel to be welded is placed on the ridge of the factory building to be installed. The positioning device is moved to the tail end of the roof panel by moving the support assembly. The distance of the positioning device below the roof panel installation is aligned using a distance marked by an external reference object. By activating the adjusting cylinder group, the top of the cylinder extension rod moves upward and applies a supporting force to the limiting frame through the retaining rod, thereby driving the limiting... The frame rotates around a round rod as an axis, adjusting the tilt angle of the clamping plate to fit the roof panel to be welded. The clamping plate engages with the bottom end of the roof panel, bringing one end of the roof panel into contact with the pressure sensor on the clamping plate. The pressure data collected by the pressure sensor is displayed on a screen, confirming whether the tail end of the roof panel is flush. Indicator lights, whether on or off or colored, indicate alignment, providing a quick assessment of the tail end's alignment. The height of the electromagnetic adsorption plate is adjusted by activating the hydraulic cylinder, while the transition frame and T-shaped traction rod at the top of the hydraulic cylinder pull the electromagnetic adsorption plate until it is parallel to the top surface of the clamping plate. Activating the electromagnetic adsorption plate applies attraction to the bottom of the roof panel, preventing displacement during welding and improving the welding quality between the roof panel and the ridge.

[0007] As a further aspect of the present invention: the mobile support component includes a support plate, with movable wheels installed at both ends of the support plate and a protective frame installed on the top of the support plate. The movable wheels are used to move the positioning device, and the protective frame serves to protect the positioning device on the one hand, and facilitates the application of pushing and pulling forces to the positioning device on the other hand.

[0008] As a further aspect of the present invention: the vertical height adjustment assembly includes a support hydraulic rod connected to the support plate and rod A and rod B interlaced and connected by a positioning shaft. A push plate is welded to the top of the support hydraulic rod, and the top of the push plate is fixed to rod A. The vertical height adjustment assembly can increase the overall height of the positioning device by increasing the angle between rod A and rod B.

[0009] As a further aspect of the present invention: the adjusting cylinder assembly includes at least two symmetrical cylinders, the top surface of the wedge seat is a slope with an inclination angle not exceeding 60°, used to maintain the support inclination angle of the cylinder extension rod, and the wedge seat is used to maintain the angle between the adjusting cylinder assembly and the horizontal plane.

[0010] As a further aspect of the present invention: the alignment assembly includes pressure sensors, a display screen, and indicator lights installed at both ends of the snap-fit ​​plate. The pressure sensors are used to detect the pressure applied by the roof panel to both ends of the snap-fit ​​plate. A stabilizing rod is movably connected to one end of the snap-fit ​​plate. The pressure sensors are used to detect the pressure at both ends of the roof panel snapping into the snap-fit ​​plate. When the pressure values ​​detected by the two pressure sensors are within the allowable range, it indicates that the alignment degree of the tail end of the roof panel has reached the expected level. When the tail end of the roof panel is aligned, the bulb in the indicator light that indicates alignment is lit. If the alignment accuracy does not reach the expected level, the indicator light is off or the bulb that indicates misalignment is lit.

[0011] As a further aspect of the present invention: the adjusting hydraulic cylinder includes a hydraulic cylinder and a transition frame connected to the top of the hydraulic cylinder. A T-shaped traction rod is welded to the top of the transition frame. The top of the T-shaped traction rod passes through a limit frame. The transition frame is used to connect the force-applying hydraulic cylinder and the T-shaped traction rod. The T-shaped traction rod applies a supporting force or a pulling force to the limit frame to adjust the rise or fall of the electromagnetic adsorption plate.

[0012] As a further aspect of the present invention: the bottom of the force-applying hydraulic cylinder and the adjusting hydraulic cylinder are respectively welded with a base plate with threaded holes. The base plate is detachably connected to the movable seat. The bottom of the force-applying hydraulic cylinder and the adjusting hydraulic cylinder are disassembled and installed by bolts, which facilitates the maintenance and replacement of the force-applying hydraulic cylinder and the adjusting hydraulic cylinder.

[0013] As a further aspect of the present invention: rectangular openings are respectively provided on both sides of the limiting frame, and the two ends of the T-shaped traction rod pass through the rectangular openings respectively. The rectangular openings limit the T-shaped traction rod and improve the adjustment stability of the positioning device.

[0014] As a further aspect of the present invention: the suction cup assembly includes an electromagnetic adsorption plate, the top of which has a plurality of equally spaced suction holes for adsorbing the bottom surface of the roof panel and preventing the roof panel from shifting.

[0015] As a further aspect of the present invention: both the electromagnetic adsorption plate and the snap-fit ​​plate are inclined structures, and the snap-fit ​​surfaces of the electromagnetic adsorption plate and the snap-fit ​​plate are coplanar, thereby ensuring the positioning strength of the roof panel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, an alignment component is installed at one end of the snap-fit ​​plate to align the welding positions of the roof panel and the ridge. The alignment component strengthens the contact area between the roof panel and the ridge and reduces the distance between them, which can reduce slag inclusions, incomplete fusion and porosity defects at the weld and improve the welding accuracy of the weld between the roof panel and the ridge.

[0018] 2. In this invention, by activating the electromagnetic adsorption disk to apply an attractive force to the bottom of the roof panel, displacement of the roof panel during welding is prevented, thereby improving the welding quality between the roof panel and the ridge weld.

[0019] 3. In this invention, by setting a movable support component, it can be used to support and move the positioning device. The top of the movable support component is equipped with a vertical height adjustment component, which facilitates the adjustment of the overall vertical height of the positioning device, thereby adapting the vertical height adjustment component to the installation height of the factory roof panel.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0030] Please see Figures 1-8In this embodiment of the invention, a positioning device for assembling steel structure components includes a movable support component 1 for supporting and moving the positioning device. A rechargeable power supply is installed inside the movable support component 1. A vertical height adjustment component 2 is connected to the top of the movable support component 1 for adjusting the overall vertical height of the positioning device, thereby adapting the vertical height adjustment component 2 to the installation height of the factory roof panel. A roof panel end-clamping component 3 is connected to the top of the vertical height adjustment component 2 via a positioning block 301, for angle clamping and positioning of the roof panel along the roof's inclined surface, and for facilitating the clamping and positioning of the roof panel to be welded at the welding position on the factory roof ridge, thus facilitating alignment of the roof panel with the roof. The welding joint between the roof ridges improves the ease of welding between the roof panels and the ridges while also enhancing the welding quality at the weld seams. The roof panel end clamping assembly 3 includes a limiting groove 302 and an adjusting cylinder assembly 304 connected within the limiting groove 302 via a wedge-shaped seat 303. The top of the adjusting cylinder assembly 304 is connected to a retaining rod 306 via a cylinder telescopic rod 305. Both ends of the retaining rod 306 pass through a limiting frame 307. The lower end of the limiting frame 307 is connected to the limiting groove 302 via a round rod 309 and a bearing. The adjusting cylinder assembly 304 adjusts the rotation angle of the limiting frame 307 around the round rod 309 via the cylinder telescopic rod 305, thereby further adjusting the rotation angle of the limiting frame 307. The tilt angle of the top surface of the connecting rod 308 allows the retaining rod 306 to slide inside the limiting frame 307 during vertical rotation. The limiting frame 307 limits the movement distance of the retaining rod 306. A snap-fit ​​plate 601 is bolted to the top of the limiting frame 307 via the connecting rod 308. One end of the snap-fit ​​plate 601 is equipped with an alignment component 6 for aligning the welding positions of the roof panel and the ridge, improving the welding accuracy at the roof panel and ridge weld. By strengthening the contact area between the roof panel and the ridge and reducing the distance between them through the alignment component 6, slag inclusions, incomplete fusion, and porosity defects at the weld can be reduced. The alignment component 6 includes components installed on the snap-fit ​​plate 308. The connector plate 601 includes pressure sensors 605, a display screen 603, and indicator lights 604 at both ends. Pressure sensors 605 detect the pressure applied by the roof panel to both ends of the connector plate 601. A stabilizing rod 602 is movably connected to one end of the connector plate 601. Pressure sensors 605 detect the pressure at both ends of the roof panel when it is snapped into the connector plate 601. When the pressure values ​​detected by the two pressure sensors 605 are within the allowable range, it indicates that the alignment of the tail end of the roof panel has reached the expected level. When the tail end of the roof panel is aligned, the bulb in the indicator light 604 that indicates alignment is lit. If the alignment accuracy does not reach the expected level, the indicator light 604 is off or the bulb that indicates misalignment is lit.The roof panel bottom support assembly 4 includes a drive motor 401 installed on the side of the limiting groove 302. The input end of the drive motor 401 is electrically connected to an external power source. When the drive motor 401 is started, it drives a driven wheel 403 through its output end to mesh with a driven wheel 403. A driven shaft 404 passes through the interior of the driven wheel 403. A limiting rod 405 is fixed to the inner wall of the limiting groove 302. A movable seat 406 is connected to the surfaces of the driven shaft 404 and the limiting rod 405. The top of the movable seat 406 is connected to the suction cup assembly 5 through a force-applying hydraulic cylinder 409 and an adjusting hydraulic cylinder 408. The adjusting hydraulic cylinder includes a hydraulic cylinder and a transition frame 502 connected to the top of the hydraulic cylinder. A T-shaped traction rod 501 is welded to the top of the transition frame 502. The top of the T-shaped traction rod 501 passes through the limiting frame 503. The transition frame 502 is used to connect the force-applying hydraulic cylinder 409 and the T-shaped traction rod 501. The T-shaped traction rod 501 applies a supporting force or pulling force to the limiting frame 503 to adjust the rise or fall of the electromagnetic adsorption plate 505. Rectangular openings 504 are respectively opened on both sides of the limiting frame 503. The two ends of the T-shaped traction rod 501 pass through the rectangular openings 504 respectively. The rectangular openings 504 limit the T-shaped traction rod 501 and improve the stability of the positioning device adjustment. The bottom of the force-applying hydraulic cylinder 409 and the adjusting hydraulic cylinder 408 are respectively welded with a base plate 407 with threaded holes. The base plate 407 is detachably connected to the moving seat 406. The bottom of the force-applying hydraulic cylinder 409 and the adjusting hydraulic cylinder 408 are connected to the bottom of the moving seat 406. The bolt-on disassembly and installation facilitates the maintenance and replacement of the hydraulic cylinder 409 and the adjusting hydraulic cylinder 408. During use, the roof panel to be welded is placed on the ridge of the factory building to be installed. The positioning device is moved to the tail end of the roof panel by moving the support assembly 1. The distance between the positioning device and the roof panel installation is aligned using an external reference mark. By activating the adjusting cylinder assembly 304, the top of the cylinder extension rod 305 moves upward and applies support force to the limiting frame 307 through the retaining rod 306, thereby causing the limiting frame 307 to rotate around the round rod 309 as an axis. The tilt angle of the snap-fit ​​plate 601 is adjusted and adapted to the roof panel to be welded. The snap-fit ​​plate 601 is engaged with the bottom end of the roof panel, so that one end of the roof panel is aligned with the snap-fit ​​plate 601. The pressure sensor 605 contacts the roof panel, and the pressure data collected by the pressure sensor 605 is displayed on the display screen 603. This allows confirmation of whether the tail end of the roof panel is flush. The alignment of the roof panel is indicated by the on / off state or the color of the indicator light 604, thus quickly assessing the alignment degree of the roof panel tail end. The working height of the electromagnetic adsorption plate 505 is adjusted by activating the force-applying hydraulic cylinder 409. Simultaneously, the transition frame 502 at the top of the hydraulic cylinder 408 and the T-shaped traction rod 501 are adjusted to pull the electromagnetic adsorption plate 505 to rotate until it is parallel to the top surface of the snap-fit ​​plate 601. Activating the electromagnetic adsorption plate 505 applies a gravitational pull to the bottom of the roof panel, thereby preventing the roof panel from shifting during welding and improving the welding quality between the roof panel and the ridge weld.

[0031] Preferred, such as Figure 1 As shown, the mobile support assembly 1 includes a support plate 101, with moving wheels 102 installed at both ends of the support plate 101 and a protective frame 103 installed on the top of the support plate 101. The moving wheels 102 are used to move the positioning device, and the protective frame 103 is used to protect the positioning device on the one hand, and on the other hand, the protective frame 103 facilitates the application of pushing and pulling forces to the positioning device.

[0032] Preferred, such as Figure 1 As shown, the vertical height adjustment assembly 2 includes a support hydraulic rod 201 connected to the support plate 101 and rod A 203 and rod B 205 interlaced and connected by a positioning shaft 204. A push plate 202 is welded to the top of the support hydraulic rod 201, and the top of the push plate 202 is fixed to rod A 203. The vertical height adjustment assembly 2 can increase the overall height of the positioning device by increasing the angle between rod A 203 and rod B 205.

[0033] Preferred, such as Figure 3 As shown, the adjusting cylinder assembly 304 includes at least two symmetrical cylinders. The top surface of the wedge seat 303 is a slope with an inclination angle not exceeding 60°, which is used to maintain the support inclination angle of the cylinder extension rod 305. The wedge seat 303 is used to maintain the angle between the adjusting cylinder assembly 304 and the horizontal plane.

[0034] Preferred, such as Figure 1 and Figure 2 As shown, the suction cup assembly 5 includes an electromagnetic adsorption plate 505. The top of the electromagnetic adsorption plate 505 has multiple equally spaced suction holes for adsorbing the bottom surface of the roof panel and preventing the roof panel from shifting.

[0035] Preferred, such as Figure 1 and Figure 5 As shown, both the electromagnetic adsorption plate 505 and the snap-fit ​​plate 601 are inclined structures, and the snap-fit ​​surfaces of the electromagnetic adsorption plate 505 and the snap-fit ​​plate 601 are coplanar, thereby ensuring the positioning strength of the roof panel.

[0036] The working principle of this invention is as follows: In use, the input end of the drive motor 401 is electrically connected to an external power source. The roof panel to be welded is placed on the ridge of the factory building to be installed. The positioning device is moved to the tail end of the roof panel by moving the support assembly 1. The distance of the positioning device below the roof panel is aligned by using the distance marked by an external reference object. A push plate 202 is welded to the top of the supporting hydraulic rod 201. The top of the push plate 202 is fixed to the first rod 203. The vertical height adjustment assembly 2 can increase the overall height of the positioning device by increasing the angle between the first rod 203 and the second rod 205. By activating the adjusting cylinder group 304, the top of the cylinder extension rod 305 moves upward and applies a supporting force to the limiting frame 307 through the holding rod 306, thereby driving the limiting frame 307 to rotate around the round rod 309 as the axis. The tilt angle of the snap-fit ​​plate 601 is adjusted and adapted to the roof panel to be welded. The snap-fit ​​plate 601 is connected to the roof. The bottom end of the plate is fitted with a snap-fit, so that one end of the roof panel contacts the pressure sensor 605 at one end of the snap-fit ​​plate 601. The pressure sensor 605 is used to detect the pressure at both ends of the roof panel when it is snapped into the snap-fit ​​plate 601. When the pressure values ​​detected by the two pressure sensors 605 are within the allowable range, it means that the alignment of the tail end of the roof panel has reached the expected level. When the tail end of the roof panel is aligned, the bulb in the indicator light 604 that indicates alignment lights up. If the alignment accuracy does not reach the expected level, the indicator light 604 is off or the bulb that indicates misalignment lights up. The working height of the electromagnetic adsorption plate 505 is adjusted by activating the force-applying hydraulic cylinder 409. At the same time, the electromagnetic adsorption plate 505 is rotated to be parallel to the top surface of the snap-fit ​​plate 601 by adjusting the transition frame 502 at the top of the hydraulic cylinder 408. The electromagnetic adsorption plate 505 is activated to apply an attractive force to the bottom of the roof panel, thereby preventing the roof panel from shifting during welding.
