Description

Technical Field

[0001] This invention belongs to the technical field of welding auxiliary equipment, and specifically relates to a welding auxiliary device for prefabricated components. Background Technology

[0002] With the continuous improvement of domestic industrialization, the span and width of buildings are constantly increasing, and high-rise and super high-rise buildings are emerging one after another. However, on-site fabrication of large components is not only time-consuming and inefficient, but also easily causes environmental pollution. Therefore, prefabricated component technology is developing rapidly. Compared with traditional on-site fabrication, prefabricated component technology can not only reduce construction time and labor costs and improve project efficiency, but its standardized design and construction process can also reduce construction errors and waste, thereby reducing the overall construction cost. In prefabricated component technology, the assembly of prefabricated components inevitably involves overhead and downward welding, which brings great construction difficulties to the workers. Furthermore, the sizes and shapes of prefabricated components are diverse, and the existing splicing equipment is not very versatile and cannot meet the positioning requirements of most prefabricated components of various shapes and sizes. At the same time, the existing splicing equipment is inconvenient to assemble and disassemble and is not convenient to transport. Summary of the Invention

[0003] In view of the above-mentioned problems in the prior art, the technical problem to be solved by the present invention is to provide a prefabricated component welding auxiliary device to meet the positioning of prefabricated components of different shapes and sizes.

[0004] Technical Solution: To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A precast component welding auxiliary device includes a lift, a drive device mounted on the lift, and an annular rotating plate movably connected to the drive device. The inner surface of the annular rotating plate has two or more telescopic components, each connected to a clamping component for clamping the precast component. Each telescopic component includes a first body, a second body fitted inside the first body, and a third body fitted inside the second body. The first body contains a first motor and a first screw connected to the first motor. The second body has a first screw hole corresponding to the first screw. Two pulleys are movably connected to the side walls of the second body, and a transmission belt is fitted between the two pulleys. A first fixing block connected to the transmission belt is located on the inner wall of the first body, and a second fixing block connected to the transmission belt is located on the outer wall of the third body.

[0006] Preferably, the clamping assembly includes a driving component, a support platform connected to the driving component, and a pad disposed on the support platform. The driving component includes two symmetrically arranged support plates, a first drive motor disposed on the support plate, a drive shaft connected to the first drive motor, and a first conical tooth disposed on the drive shaft. The support platform is provided with a support column, and the support column is provided with a second conical tooth corresponding to the first conical tooth. A swing crank is sleeved on the support column, and the swing crank is movably connected to the drive shaft.

[0007] Preferably, the driving component further includes a second driving motor disposed on the support plate, the second driving motor being connected to the swing crank, and the second driving motor driving the support platform to swing left and right through the swing crank.

[0008] Preferably, two pads are symmetrically arranged, and the two pads are hinged to form a straight line or a V-shape. The pads are movably connected to the support platform through a first telescopic rod.

[0009] Preferably, four telescopic components are provided, and the four telescopic components are arranged symmetrically.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0015] 1. By setting up a lifting platform, a drive device, and a circular rotating plate, the precast components can be positioned well, avoiding overhead welding and improving welding efficiency;

[0016] 2. Multiple lifting platforms can adjust the height and tilt angle of precast components. The telescopic components on the ring rotating plate can use a small height to drive the clamping components to extend and retract over a large range, adapting to precast components of different sizes.

[0025] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] like Figure 1 and Figure 2 As shown, a welding auxiliary device for precast components includes a lifting platform 1, a driving device 2, an annular rotating plate 3, and a guide rail plate 7. The guide rail plate 7 includes a first plate 71 and a second plate 72, which are symmetrically arranged with the first plate 71 and hinged together. The first plate 71 and the second plate 72 are respectively provided with sliding grooves. Four lifting platforms 1 are provided, and their bottoms are slidably connected to the guide rail plate 7 via sliding grooves to adjust the distance between them. The lifting platform 1 adopts an existing scissor lift, including a base 11, a support rod assembly 12 mounted on the base, and a platform 13 mounted on the support rod assembly 12. The support rod assembly 12 includes a hydraulic cylinder, and the height of the platform 13 is adjusted by the action of the hydraulic cylinder.

[0027] like Figure 3As shown, the four lifting platforms 1 are connected by a six-bar linkage 6. The six-bar linkage 6 includes two symmetrically arranged side bars 61. Each side bar 61 is movably connected to two long bars 62. The long bars 62 on each side bar 61 are hinged to the corresponding long bars 62 on the other side bar 61 through hinge shafts 64. Short bars 63 are connected to the two hinge shafts 64. The other end of the short bars 63 is movably connected to the adjacent long bars 62. In use, the side bars 61 are connected to the lifting platform 1. The six-bar linkage 6 can restrict the movement of the lifting platform 1 to prevent it from slipping, thereby improving the stability of the lifting platform 1 when it moves.

[0028] like Figure 1 and Figure 4 As shown, the drive device 2 includes a housing and a second motor 21, a drive shaft 22, a drive gear 23, and a roller 24 mounted on the housing. The second motor 21 drives the drive shaft 22 to rotate. The drive gear 23 is located in the middle of the drive shaft 22 and rotates under the drive of the drive shaft 22. The roller 24 is movably connected to the drive shaft 22 to support the annular rotating plate 3. Multiple second motors 21 and drive shafts 22 are provided, and multiple drive gears 23 work synchronously. A ring of toothed grooves 31 is provided on the outer surface of the annular rotating plate 3, and the toothed grooves 31 correspond to the drive gears 23. The annular rotating plate 3 rotates under the drive of the drive gears 23.

[0029] like Figure 1 and Figure 5As shown, four telescopic components 4 are provided on the inner surface of the annular rotating plate 3. The four telescopic components 4 are symmetrically arranged. Each telescopic component 4 includes a first body 41, a second body 42, and a third body 43. The first body 41 contains a first motor 44 and a first screw 45. The first screw 45 is connected to the first motor 44 and rotates under the drive of the first motor 44. The second body 42 is fitted inside the first body 41. The bottom of the second body 42 has a first screw hole 46 corresponding to the first screw 45. When the first screw 45 rotates forward and reverses, it can drive the second body 42 to rise or fall. The third body 43 is fitted inside the second body 42. 2. Two pulleys 47 are connected to each of the two side walls. The two pulleys 47 are arranged vertically, one near the top of the second body 42 and the other near the bottom of the second body 42. The pulleys 47 are movably connected to the side walls of the second body 42 through an intermediate shaft. A transmission belt 48 is sleeved between the two pulleys 47. The transmission belt 48 is movably connected to the two pulleys 47. A first fixing block 411 is provided on the inner wall of the first body 41 near the upper pulley 47. The first fixing block 411 is fixedly connected to the transmission belt 48. A second fixing block 431 is provided on the outer wall of the third body 43 near the lower pulley 47. The second fixing block 431 is fixedly connected to the transmission belt 48. When the second body 42 moves upward under the drive of the first screw 45, the two pulleys 47 are positioned upward, while the first fixed block 411 remains stationary. Since the pulleys 47 are movably connected to the side wall of the second body 42, the pulleys 47 will rotate when the second body 42 moves upward. The transmission belt 48 at the fixed end of the first fixed block 411 moves downward relative to the first fixed block 411, and thus the transmission belt 48 at the fixed end of the second fixed block 431 moves upward relative to the second fixed block 431. As a result, the second fixed block 431 drives the third body 43 to move upward, achieving the purpose of synchronous lifting and lowering with the second body 42.

[0030] like Figure 1 , Figure 5 and Figure 6As shown, a clamping assembly 5 is movably connected to the telescopic assembly 4. The telescopic assembly 4 can adjust the height of the clamping assembly 5. The clamping assembly 5 includes a driving component, a support platform 57, and two pads 59. The driving component includes a support plate 51, a first drive motor 53, a drive shaft, a first conical tooth 54, and a second drive motor 52. The support plate 51 is an L-shaped plate and two are symmetrically arranged. The support plate 51 is connected to the inner wall of the third body 43. The first drive motor 53 is mounted on one of the support plates 51, and the second drive motor 52 is mounted on the other support plate 51. The drive shaft is connected to the first drive motor 53. The first conical tooth 54 is mounted on the drive shaft. The first drive motor 53 drives the first conical tooth 54 to rotate. The support platform 57 is a circular platform. A support column 571 is provided on the back of the support platform 57. The support column 571 is provided with a second conical tooth 55. The second conical tooth 55 is set perpendicular to the first conical tooth 54. When the first conical tooth 54 rotates, it drives the second conical tooth 55 to rotate, thereby driving the support platform 57 to rotate. A swing crank 56 is sleeved on the support column 571. The two ends of the swing crank 56 are movably connected to the drive shaft. The second drive motor 52 is connected to one end of the swing crank 56, thereby driving the swing crank 56 to swing left and right. When the swing crank 56 swings, it drives the support platform 57 to swing. The drive component and the support platform 57 are both set in the third body 43. The swing angle of the support platform 57 is relatively small. The two pads 59 are hinged together, forming a straight line or a V-shape. The back of the pads 59 is movably connected to the support platform 57 via the first telescopic rod 58. The angle between the two pads 59 can be adjusted by the movement of the two first telescopic rods 58. When the two pads 59 are in a straight line, they can rest on a flat surface, which is suitable for rectangular components. When they are in a V-shape, they can rest on an arc surface, which is suitable for column components of different diameters. Since the support platform 57 can rotate, the position of the two pads 59 can be adjusted, and the support platform 57 can swing within a small range. The two pads 59 can adapt to the tilt of the precast components.

[0031] like Figure 1 As shown, the annular rotating plate 3 is a circular plate. The annular rotating plate 3 includes a first arc plate 301 and a second arc plate 302. The first arc plate 301 is a minor arc plate, and the second arc plate 302 is a major arc plate. Three of the four telescopic components 4 are set on the second arc plate 302. The first arc plate 301 is detachably connected to the second arc plate 302 at the bottom by bolts.

[0032] The steps for using this device are as follows:

[0033] 1) Estimate the dimensions of the prefabricated components and the weld dimensions in advance to determine the distance between the two middle elevators 1, and then place them at the designated points;

[0034] 2) After determining the length of the precast component, slide the other two elevators 1 to the predetermined position;

[0035] 3) Adjust the height of the two pads 59 on the clamping assembly 5 and the angle of the V-shape according to the size of the precast component.

[0036] 4) Then, using a crane, the precast component is hoisted onto the bottom clamping assembly 5 of the second arc plate 302. The clamping assemblies 5 on both sides of the inner ring of the annular rotating plate 3 are adjusted to fix the precast component.

[0037] 5) Connect the first arc plate 301 to the second arc plate 302, adjust the clamping component 5 on the first arc plate 301 to a suitable position, and fix the prefabricated component from above;

[0038] 6) After placing the precast components, slowly raise the elevators 1 on both sides. When they are raised to the predetermined height and angle, the precast components are fixed by the pads 59 on the clamping assembly 5.

[0039] 7) After the ends of the precast components that need to be welded are aligned, the welding gun of the automatic welding device is aligned with the weld seam; during welding, the drive device 2 drives the annular rotating plate 3 to rotate together, thereby driving the precast components to rotate the unwelded parts to the position of the welding gun, and continue welding; after the weld seam is completed and solidified, the annular rotating plate 3 is rotated back to the initial position, and then the first arc plate 301 is disassembled to lift the assembled precast components away.

[0040] It is evident that using this device for automated welding of precast components is convenient and easy to operate, greatly saving manpower and avoiding overhead welding, thus improving welding quality. Furthermore, the device is suitable for assembling steel components of different sizes, cross-sections, and angles, making it widely applicable. In addition, the device is easy to disassemble, greatly improving its portability for transportation.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
