Description

Technical Field

[0001] This invention relates to the field of steel truss construction technology, specifically to a device and method for assembling and adjusting steel truss segments. Background Technology

[0002] Steel truss beams are a common type of steel structure beam, frequently used in construction projects such as buildings, bridges, and utility tunnels. The assembly process is a crucial step in the construction of steel truss beams. Proper assembly techniques can maximize the quality and stability of the steel truss beams, minimizing the occurrence of accidents. Steel truss beams can be erected using various methods depending on the actual terrain, offering flexibility in construction methods. Commonly used construction methods for steel truss beams include the scaffolding method, cantilever assembly method, jacking method, towing method, floating towing method, floating transport method, whole-span hoisting method, and rotation method.

[0003] Traditional steel truss segments still have some problems during assembly: the structure is relatively simple and effective assembly and adjustment are not possible. To address these issues, we propose an assembly and adjustment device and method for steel truss segments. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly and adjustment device and method for steel truss girder segments to solve the problems mentioned in the background art.

[0006] As a preferred embodiment of the present invention, the transfer mechanism includes two symmetrically distributed sets of U-shaped frames and two symmetrically distributed first T-shaped roller rails. The first T-shaped roller rails are fixedly installed on both sides of the top end of the first steel truss segment by bolts. A first connecting frame is fixedly installed at the top end of each set of U-shaped frames. A drive shaft is rotatably installed on both sides of the bottom of the two sets of U-shaped frames. A first concave roller that cooperates with the first T-shaped roller rail is fixedly installed on each drive shaft. The first concave roller is rolled and engaged on the corresponding first T-shaped roller rail. A U-shaped frame is fixedly installed at the opposite ends of the two first T-shaped roller rails. The U-shaped frame is fixedly installed on the first steel truss segment by bolts. A transfer gear is fixedly installed on the side of the drive shaft near the U-shaped frame. A transfer rack that cooperates with the transfer gear is fixedly engaged in the U-shaped frame. The transfer gear and the corresponding transfer rack are meshed and connected.

[0007] As a preferred embodiment of the present invention, the stabilizing mechanism includes a stabilizing crossbeam and an L-shaped bracket. The stabilizing crossbeam has multiple components corresponding to the first connecting frame. The stabilizing crossbeam is fixedly installed on two sets of U-shaped frames horizontally between the first connecting frames. The L-shaped bracket has multiple evenly distributed sets. Each set of L-shaped brackets is fixedly installed on the opposite side of the corresponding first T-shaped roller rail. Rotating frames are fixedly installed on both sides of the bottom end of the stabilizing crossbeam. An auxiliary shaft is rotatably installed on the bottom of each rotating frame. A second T-shaped roller rail is fixedly installed on the top end of each set of L-shaped brackets. A second concave roller is fixedly installed on the end of each auxiliary shaft. The second concave roller is rolled and engaged on the corresponding second T-shaped roller rail.

[0008] As a preferred embodiment of the present invention, the extension member includes two symmetrically distributed extension frames, the extension frames having a rhomboid structure, and a uniformly distributed second connecting frame fixedly installed between the two extension frames, and a mounting base fixedly installed at the bottom end of each extension frame.

[0009] As a preferred embodiment of the present invention, the mounting base is provided with a plurality of first connecting frames, and the mounting base is fixedly mounted on the top of the corresponding first connecting frame by bolts.

[0010] As a preferred embodiment of the present invention, the feeding assembly includes two symmetrically distributed mounting crossbeams. The mounting crossbeams are fixedly installed on the side of the extension frame away from the mounting base. A U-shaped longitudinal frame is fixedly installed at the bottom of each mounting crossbeam. The bottom of the U-shaped longitudinal frame passes through the extension frame. Two symmetrically distributed feeding machines are fixedly installed on opposite sides of the bottom of the two U-shaped longitudinal frames. A feeding crossbeam is fixedly installed at the feeding rope end of each feeding machine. A material fixing component is fixedly installed on both sides of the top of each feeding crossbeam.

[0011] As a preferred embodiment of the present invention, the second steel truss segment can be detachably installed on multiple fixed components.

[0012] As a preferred embodiment of the present invention, the adjustment mechanism includes a connecting auxiliary frame, which has four symmetrically distributed sets. The connecting auxiliary frame is fixedly installed at both ends of the opposite side of the corresponding U-shaped longitudinal frame. An auxiliary crossbar is fixedly installed at the end of the connecting auxiliary frame away from the U-shaped longitudinal frame. A linear electric rail is fixedly installed at the bottom end of each auxiliary crossbar. An electric lifting rod is fixedly installed at the drive end of each linear electric rail. A clamping component is fixedly installed at the drive end of each electric lifting rod.

[0013] As a preferred embodiment of the present invention, the clamping member and the feeding crossbar are used in cooperation with each other.

[0014] A method for assembling and adjusting steel truss girder segments includes the following steps:

[0015] Step 1: Secure the first T-shaped roller rail to each steel truss segment with bolts. Then, install two sets of U-shaped frames, first concave rollers, and transfer gears on the assembled steel truss segments. The transfer gears mesh with the corresponding transfer racks and are connected to an external drive mechanism at the end of one of the drive shafts. Also install a stabilizing mechanism and extension parts. The first concave rollers are rolled and engaged at the top of the corresponding first T-shaped roller rails, and the second concave rollers are rolled and engaged at the bottom of the corresponding second T-shaped roller rails. The first T-shaped roller rails and the second concave rollers are used to position the two sets of U-shaped frames on the assembled steel truss segments using rollers to prevent the U-shaped frames from detaching.

[0016] Step 2: When a new steel truss segment needs to be assembled, the external drive mechanism is activated, driving one of the drive shafts to rotate, which in turn drives the corresponding transfer gear to rotate. Since the transfer gear and the corresponding transfer rack are meshed, the transfer rack drives the transfer gear and the corresponding drive shaft to move, thereby driving the corresponding first concave roller to be positioned and rolled on the corresponding first T-shaped roller rail. This drives the U-shaped frame to move parallel on the assembled steel truss segment, and the second concave roller rolls on the corresponding second T-shaped roller rail, driving the extension piece, the feeding assembly, and the adjustment mechanism to move automatically in parallel until the extension piece, the feeding assembly, and the adjustment mechanism move to the end position of the assembled steel truss segment. Since the extension frame has a diamond-shaped structure, the feeding assembly and the adjustment mechanism extend beyond the end position of the assembled steel truss segment.

[0017] Step 3: Install the steel truss girder segment onto multiple fixed parts, turn on the feeding machine to drive the feeding crossbeam, multiple fixed parts and steel truss girder segment to rise, and automatically feed the steel truss girder segment until the horizontal position of the steel truss girder segment corresponds to that of the installed steel truss girder segment.

[0018] Step 4: During automatic feeding, control the activation of the linear electric rail to drive the clamping component to move parallel, and control the activation of the electric lifting rod to drive the clamping component to move up and down until the feeding crossbeam is clamped on the clamping component. Control the use of the clamping component to assist in clamping and positioning the feeding crossbeam. Subsequently, control the activation of the linear electric rail to drive the clamping component to move parallel, thereby assisting in driving the feeding crossbeam and the steel truss segment to be installed to move parallel, and then assisting in automatically adjusting the position of the steel truss segment so that the position of the installed steel truss segment corresponds to the installation position of the steel truss segment after installation. Then, drive the U-shaped frame to move parallel in the opposite direction on the installed steel truss segment, driving the installed steel truss segment to move parallel in the opposite direction to the position of the installed steel truss segment, which facilitates the positioning and installation between the steel truss segments.

[0019] Step 5: After the steel truss segment is assembled, the drive U-shaped frame is moved parallel to the assembled steel truss segment again, and then moved to the end position of the assembled steel truss segment to facilitate the assembly of the next steel truss segment.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By setting up a transfer drive mechanism, and using extension parts, feeding components and adjustment mechanisms, the steel truss girder segments are automatically fed and the position of the steel truss girder segments is automatically adjusted. At the same time, the installed steel truss girder segments are moved in the opposite parallel direction to the position of the installed steel truss girder segments, which facilitates the positioning and installation between steel truss girder segments, improves the assembly efficiency and quality of steel truss girder segments, and facilitates the assembly of multiple steel truss girder segments in the future.

[0022] 2. By setting up a stabilizing mechanism, the first concave roller is rolled and engaged at the top of the corresponding first T-shaped roller rail, and the second concave roller is rolled and engaged at the bottom of the corresponding second T-shaped roller rail. The first T-shaped roller rail and the second concave roller are used to perform roller-type positioning of the two sets of U-shaped frames on the first steel truss segment, preventing the U-shaped frame from falling off, improving the stability of the extension parts, feeding components and adjustment mechanisms when they move, and improving the stability of the steel truss segment assembly.

[0033] 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.

[0034] Example: Figure 1-8 As shown, the present invention provides an assembly and adjustment device for steel truss girder segments, including a first steel truss girder segment 1, an extension 2 at the top of the first steel truss girder segment 1, a transfer mechanism 3 between the bottom end of the extension 2 and the top end of the first steel truss girder segment 1, a stabilizing mechanism 4 on the transfer mechanism 3, a feeding assembly 5 on the extension 2, an adjustment mechanism 6 on the feeding assembly 5, and a second steel truss girder segment 7 detachably installed at the bottom end of the feeding assembly 5.

[0035] The displacement mechanism 3 includes two symmetrically distributed sets of U-shaped frames 31 and two symmetrically distributed first T-shaped roller rails 32. The first T-shaped roller rails 32 are fixedly installed on both sides of the top of the first steel truss segment 1 by bolts. A first connecting frame 311 is fixedly installed at the top of each set of U-shaped frames 31. A drive shaft 33 is rotatably installed on both sides of the bottom of the two sets of U-shaped frames 31. A first concave roller 34 that cooperates with the first T-shaped roller rail 32 is fixedly installed on each drive shaft 33. The first concave roller 34 rolls and engages with the corresponding first T-shaped roller rail 32. By setting the first concave roller 34 and cooperating with the first T-shaped roller rail 32, the first concave roller 34 can be positioned and rolled on the corresponding first T-shaped roller rail 32. U-shaped roller rails 32 are fixedly installed on opposite ends of the two first T-shaped roller rails 32. The U-shaped frame 35 is bolted to the first steel truss segment 1. A transfer gear 36 is fixedly installed on the side of each drive shaft 33 near the U-shaped frame 35. A transfer rack 361, which works in conjunction with the transfer gear 36, is fixedly inserted into each U-shaped frame 35. The transfer gear 36 and the corresponding transfer rack 361 mesh with each other. In practical use, one end of one drive shaft 33 can be connected to an external drive mechanism to control and activate the external drive mechanism, driving one drive shaft 33 to rotate, which in turn drives the corresponding transfer gear 36 to rotate. Since the transfer gear 36 and the corresponding transfer rack 361 mesh with each other, the transfer rack 361 drives the transfer gear 36 and the corresponding drive shaft 33 to move, thereby causing the corresponding first concave roller 34 to be positioned and rolled on the corresponding first T-shaped roller rail 32, driving a set of U-shaped frames 31 to move parallel on the first steel truss segment 1.

[0036] The stabilizing mechanism 4 includes a stabilizing crossbeam 41 and L-shaped brackets 42. The stabilizing crossbeam 41 has multiple components corresponding to the first connecting frame 311. The stabilizing crossbeam 41 is fixedly installed horizontally between two sets of U-shaped frames 31, corresponding to the first connecting frame 311. By setting the stabilizing crossbeam 41, the two sets of U-shaped frames 31 are fixedly installed together. Driving one set of U-shaped frames 31 to move parallel on the first steel truss segment 1 drives the other set of U-shaped frames 31 to move parallel on the first steel truss segment 1. The L-shaped brackets 42 have multiple evenly distributed sets. Each set of L-shaped brackets 42 is fixedly installed on the opposite side of the corresponding first T-shaped roller rail 32. Rotating frames 43 are fixedly installed on both sides of the bottom end of the stabilizing crossbeam 41. Auxiliary shafts 44 are rotatably installed at the bottom of each rotating frame 43. 44 can rotate at the bottom of the rotating frame 43. A second T-shaped roller rail 46 is fixedly installed at the top of each set of L-shaped brackets 42. A second concave roller 45 is fixedly installed at the end of each auxiliary shaft 44. The second concave roller 45 is rolled and engaged on the corresponding second T-shaped roller rail 46. After specific installation, the first concave roller 34 is rolled and engaged at the top of the corresponding first T-shaped roller rail 32, and the second concave roller 45 is rolled and engaged at the bottom of the corresponding second T-shaped roller rail 46. The first T-shaped roller rail 32 and the second concave roller 45 are used to perform roller-type positioning of the two sets of U-shaped frames 31 on the first steel truss segment 1 to prevent the U-shaped frame 31 from falling off. When the U-shaped frame 31 moves parallel on the first steel truss segment 1, the second concave roller 45 rolls on the corresponding second T-shaped roller rail 46.

[0037] The extension component 2 includes two symmetrically distributed extension frames 21, each with a rhomboid structure. A uniformly distributed second connecting frame 22 is fixedly installed between the two extension frames 21. Multiple second connecting frames 22 are used to connect and fix the two extension frames 21. A mounting base 23 is fixedly installed at the bottom of each extension frame 21. Multiple mounting bases 23 are provided, each corresponding to a first connecting frame 311. The mounting base 23 is fixedly installed on the top of the corresponding first connecting frame 311 by bolts, thus fixing the extension component 2 and the transfer mechanism 3. The U-shaped frame 31 moves parallel to the first steel truss segment 1, driving the extension component 2 to move automatically in parallel.

[0038] The feeding assembly 5 includes two symmetrically distributed mounting crossbeams 51. The mounting crossbeams 51 are fixedly installed on the side of the extension frame 21 away from the mounting base 23. A U-shaped longitudinal frame 52 is fixedly installed at the bottom of each mounting crossbeam 51. The bottom of the U-shaped longitudinal frame 52 passes through the extension frame 21. Two symmetrically distributed feeding machines 53 are fixedly installed on opposite sides of the bottom of the two U-shaped longitudinal frames 52. A feeding crossbeam 54 is fixedly installed at the feeding rope end of each feeding machine 53. Fixed material components 55 are fixedly installed on both sides of the top of each feeding crossbeam 54. The second steel truss segment 7 can be detachably installed on multiple fixed material components 55. When subsequent steel truss segments need to be spliced ​​and installed, the steel truss segment is installed on multiple fixed material components 55, the feeding machine 53 is turned on, and the feeding crossbeam 54, multiple fixed material components 55 and steel truss segment are raised to automatically feed the steel truss segment until the horizontal position of the steel truss segment corresponds to that of the installed steel truss segment.

[0039] The adjustment mechanism 6 includes a connecting auxiliary frame 61, which has four symmetrically distributed sets. The connecting auxiliary frame 61 is fixedly installed at both ends of the opposite side of the corresponding U-shaped longitudinal frame 52. An auxiliary cross frame 62 is fixedly installed at the end of the connecting auxiliary frame 61 away from the U-shaped longitudinal frame 52. A linear electric rail 63 is fixedly installed at the bottom end of each auxiliary cross frame 62. An electric lifting rod 64 is fixedly installed at the drive end of each linear electric rail 63. A clamping member 65 is fixedly installed at the drive end of each electric lifting rod 64. The clamping member 65 and the feeding cross frame 54 cooperate with each other. During automatic feeding, the linear electric rail 63 is activated to drive the clamping member 65 to move parallel, and the electric lifting rod 64 is activated to drive the clamping member 65 to move up and down. The process continues until the loading crossbeam 54 is secured to the clamping member 65. The clamping member 65 is then used to assist in clamping and positioning the loading crossbeam 54. Subsequently, the linear electric rail 63 is activated again to drive the clamping member 65 to move parallel, thereby assisting in the parallel movement of the loading crossbeam 54 and the steel truss segment to be installed. This helps to automatically adjust the position of the steel truss segment, ensuring that the position of the installed steel truss segment corresponds to the installation position of the steel truss segment after installation. Then, the U-shaped frame 31 is driven to move in the opposite parallel direction on the first steel truss segment 1, causing the installed steel truss segment to move in the opposite parallel direction towards the position of the steel truss segment after installation. This facilitates the positioning and installation between steel truss segments, improving the assembly efficiency and quality of the steel truss segments.

[0040] A method for assembling and adjusting steel truss girder segments includes the following steps:

[0041] Step 1: First T-shaped roller rail 32 is fixedly installed on each steel truss segment with bolts. Then, two sets of U-shaped frames 31, first concave rollers 34, and transfer gears 36 are installed on the assembled steel truss segments. The transfer gears 36 and corresponding transfer racks 361 are meshed and connected. The end of one of the drive shafts 33 is connected to the external drive mechanism. The stabilizing mechanism 4 and the extension 2 are also installed. The first concave roller 34 is rolled and engaged on the top of the corresponding first T-shaped roller rail 32, and the second concave roller 45 is rolled and engaged on the bottom of the corresponding second T-shaped roller rail 46. The first T-shaped roller rail 32 and the second concave roller 45 are used to position the two sets of U-shaped frames 31 on the assembled steel truss segments by rollers to prevent the U-shaped frames 31 from falling off.

[0042] Step 2: When a new steel truss segment needs to be assembled, the external drive mechanism is activated, driving one of the drive shafts 33 to rotate, which in turn drives the corresponding transfer gear 36 to rotate. Since the transfer gear 36 and the corresponding transfer rack 361 are meshed, the transfer rack 361 drives the transfer gear 36 and the corresponding drive shaft 33 to move, thereby driving the corresponding first concave roller 34 to be positioned and rolled on the corresponding first T-shaped roller rail 32, driving the U-shaped frame 31 to move parallel on the assembled steel truss segment, and the second concave roller 45 to roll on the corresponding second T-shaped roller rail 46, driving the extension 2, the feeding assembly 5 and the adjustment mechanism 6 to move automatically in parallel until the extension 2, the feeding assembly 5 and the adjustment mechanism 6 move to the end position of the assembled steel truss segment. Since the extension frame 21 has a rhomboid structure, the feeding assembly 5 and the adjustment mechanism 6 extend beyond the end position of the assembled steel truss segment.

[0043] Step 3: Install the steel truss girder segment on multiple fixed parts 55, turn on the feeding machine 53, drive the feeding crossbeam 54, multiple fixed parts 55 and steel truss girder segment to rise, and automatically feed the steel truss girder segment until the horizontal position of the steel truss girder segment corresponds to that of the installed steel truss girder segment.

[0044] Step 4: During automatic feeding, control the activation of the linear electric rail 63 to drive the clamping component 65 to move parallel, and control the activation of the electric lifting rod 64 to drive the clamping component 65 to move up and down until the feeding crossbeam 54 is clamped on the clamping component 65. Control the use of the clamping component 65 to assist in clamping and positioning the feeding crossbeam 54. Subsequently, control the activation of the linear electric rail 63 again to drive the clamping component 65 to move parallel, thereby assisting in driving the feeding crossbeam 54 and the steel truss segment to be installed to move parallel, thereby assisting in automatically adjusting the position of the steel truss segment so that the position of the installed steel truss segment corresponds to the installation position of the installed steel truss segment. Then, drive the U-shaped frame 31 to move in the opposite parallel direction on the installed steel truss segment, driving the installed steel truss segment to move in the opposite parallel direction to the position of the installed steel truss segment, which facilitates the positioning and installation between the steel truss segments.

[0045] Step 5: After the steel truss segment is assembled, the drive U-shaped frame 31 is controlled to move parallel to the assembled steel truss segment again, and then moves to the end position of the assembled steel truss segment to facilitate the assembly of the next steel truss segment.

The first concave roller (34) is rolled and engaged on the top of the corresponding first T-shaped roller rail (32), and the second concave roller (45) is rolled and engaged on the bottom of the corresponding second T-shaped roller rail (46). The first T-shaped roller rail (32) and the second concave roller (45) are used to position the two sets of U-shaped frames (31) on the assembled steel truss segment by rollers to prevent the U-shaped frames (31) from falling off. Step 2: When a new steel truss segment needs to be assembled, the external drive mechanism is activated to drive one of the drive shafts (33) to rotate, which in turn drives the corresponding transfer gear (36) to rotate. Since the transfer gear (36) and the corresponding transfer rack (361) are meshed, the transfer rack (361) drives the transfer gear (36) and the corresponding drive shaft (33) to move, thereby driving the corresponding first concave roller (34) to perform positioning and rolling on the corresponding first T-shaped roller rail (32), driving the U-shaped frame (31). The second concave roller (45) moves parallel to the assembled steel truss segment, and the second T-shaped roller rail (46) rolls on the corresponding second T-shaped roller rail (46), driving the extension (2), the feeding assembly (5) and the adjustment mechanism (6) to move automatically in parallel until the extension (2), the feeding assembly (5) and the adjustment mechanism (6) move to the end position of the assembled steel truss segment. Since the extension frame (21) has a rhomboid structure, the feeding assembly (5) and the adjustment mechanism (6) extend out of the end position of the assembled steel truss segment. Step 3: Install the steel truss segment on multiple fixed parts (55), turn on the feeding machine (53), drive the feeding cross frame (54), multiple fixed parts (55) and steel truss segment to rise, and automatically feed the steel truss segment until the horizontal position of the steel truss segment corresponds to that of the installed steel truss segment. Step 4: During automatic feeding, control the opening of the linear electric rail (63) to drive the clamping component (65) to move in parallel, and control the opening of the electric lifting rod (64) to drive the clamping component (65) to move up and down until the feeding crossbeam (54) is stuck on the clamping component (65). Control the use of the clamping component (65) to assist in clamping and positioning the feeding crossbeam (54). Then, control the opening of the linear electric rail (63) again to drive the clamping component (65) to move in parallel, thereby assisting in driving the feeding crossbeam (54) and the steel truss segment to be installed to move in parallel, thereby assisting in automatically adjusting the position of the steel truss segment so that the position of the installed steel truss segment corresponds to the installation position of the installed steel truss segment. Then, drive the U-shaped frame (31) to move in the opposite parallel direction on the installed steel truss segment, thereby driving the installed steel truss segment to move in the opposite parallel direction to the position of the installed steel truss segment, which facilitates the positioning and installation between the steel truss segments. Step 5: After the steel truss segment is assembled, the drive U-shaped frame (31) is controlled to move parallel to the assembled steel truss segment again, and then moves to the end position of the assembled steel truss segment to facilitate the assembly of the next steel truss segment.
