Description

Technical Field

[0001] The present invention relates to the technical field of crossbeam assembly, and particularly relates to a high-altitude crossbeam assembly support device and a usage method thereof. Background Art

[0002] A crossbeam is a beam body horizontally arranged in a bridge span structure, perpendicular to the main piers (longitudinal beams), and plays a role in connecting the main piers to each other, dispersing loads, and enhancing the overall stiffness of the bridge. With the development of transportation construction in China, large bridges have sprung up, with the tower columns getting taller and the crossbeams getting longer. When constructing crossbeams in complex urban environments or at high altitudes, using traditional cast-in-place construction for crossbeams often faces problems such as difficult scaffold erection, large traffic impact, cumbersome construction processes, and high safety risks. While prefabricated crossbeam structures can significantly improve construction efficiency, reduce construction risks, and enable rapid installation.

[0003] Meanwhile, when installing prefabricated crossbeams in complex urban environments or at high altitudes, there are still some difficult problems: 1. Crossbeams are usually hoisted to above the main piers by lifting devices such as crawler cranes and truck cranes, and the position of the crossbeam is adjusted by adjusting the position of the crawler crane and the staff towing the cable to assist in adjusting the position of the crossbeam to achieve precise docking between the crossbeam and the main pier. The connection between the crossbeam and the main pier is usually a sleeve - threaded steel bar structure, and the general requirement for docking accuracy is less than 2 mm. Using the existing methods to adjust the alignment, the construction efficiency is low, the difficulty is high, the traffic impact is large, and there is a certain safety risk.

[0004] Therefore, it is necessary to provide a new high-altitude crossbeam assembly support device to solve the above technical problems. Summary of the Invention

[0015] The present invention also provides a usage method of an aerial beam assembly support device. This device is used in the assembly of an assembled beam erected at high altitude and a main pier. The assembled beam and the main pier are perpendicular to each other. This device is installed at the connection part between the main pier and the assembled beam and is used to support and adjust the assembly of the assembled beam. The specific usage of this device includes the following steps:

[0016] S1. Before the construction of the main pier casting is completed and before the assembled beam is installed, first fixedly install the support template in the support device on the outer wall of the template built during the main pier casting through bolts, and then fixedly install the positioning component and the supporting component on the top of the support template in sequence;

[0017] S2. Connect the assembled beam with an external lifting device; After the assembly of the device is completed, electrically connect the electrical components in the device with the controller of the terminal;

[0018] S3. Control the lifting device to hoist the assembled beam to the assembly position of the main pier, and the assembled beam is located above the supporting component;

[0019] S4. After the preliminary positioning of the assembled beam is completed, control the lateral positioning plate in the positioning component to move, so that the lateral positioning blocks the trajectory of the beam during later movement, and the assembled beam is moved to the required position according to needs;

[0020] S5. After the adjustment of the positioning component is completed, control the lifting device to pull the assembled beam, so that the assembled beam moves horizontally in the corresponding direction, and is supported and guided by the supporting component during the movement;

[0021] S6. During the movement of the assembled beam, the pressure sensor in the positioning component detects the pressure value of the lateral positioning plate to accurately control the movement position of the beam;

[0022] S7. After monitoring the position of the beam is completed, control the lifting hydraulic cylinder in the supporting component to contract, so that the beam moves downward until the assembled beam is erected on the top of the main pier, and the assembly of the beam can be completed.

[0023] A preferred technical solution of the present invention: In the step S1, a support frame is fixedly installed on the top of the prefabricated cross beam, and a projection spotlight is installed on the support frame. In the step S6, after the horizontal movement of the prefabricated cross beam is completed, the projection spotlight is controlled to irradiate, and further detect the alignment state of the cross beam.

[0024] In the step S4, when the supporting component supports and guides the prefabricated cross beam, according to the need, the longitudinal guiding roller or the transverse guiding roller in the supporting component is controlled to abut against the bottom of the cross beam, so as to support and guide the moving cross beam and improve the moving stability of the cross beam.

[0025] Compared with the related technology, the high-altitude cross beam assembly support device provided by the present invention has the following beneficial effects:

[0026] (1) Through the setting of the positioning component in the present invention, during the assembly process of the cross beam, the lateral positioning plate in the positioning component will limit and control the outer wall of the hoisted cross beam. When the side wall of the cross beam coincides with the lateral positioning plate, the positioning of the cross beam can be realized. At this time, the cross beam is vertically lowered to accurately install the cross beam on the top of the main pier, which can realize the precise docking of the cross beam assembly, reduce the fine adjustment difficulty, improve the construction efficiency, and avoid the safety risks brought by the need for personnel to assist in construction in the traditional process.

[0027] (2) Through the setting of the supporting component in the present invention, when the cross beam is horizontally moved during the assembly process, the longitudinally arranged longitudinal guiding roller and the transversely arranged transverse guiding roller in the supporting component can support and guide the horizontally moving cross beam. Compared with the simple hoisting and moving, the problem that the cross beam is easy to shake and not easy to accurately position and adjust during the suspension construction can be solved, and it can ensure that the horizontal movement and adjustment of the cross beam are faster and more stable during the assembly process.

[0028] (3) By installing a projection spotlight on the top of the cross beam in the present invention, after the positioning of the cross beam is completed, the alignment angle of the cross beam can be further determined by detecting the light of the projection spotlight, and further, the influence of the deviation of the cross beam after positioning on the subsequent insertion and assembly can be reduced.

Detailed implementation manners

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0041] Please refer to Figures 1 to 9, a high-altitude beam assembly support device provided by an embodiment of the present invention is used for the assembly of a prefabricated beam 7 erected at high altitude and a main pier 6. The support device is installed at the connection part between the main pier 6 and the prefabricated beam 7 and is used for supporting the prefabricated beam 7. The support device includes a support formwork 1 and a positioning assembly 2. There are two support formworks 1, which are symmetrically distributed. Installation holes 9 matching the main pier casting formwork 8 are provided at the butt joint part of the two support formworks 1. There are multiple groups of positioning assemblies, which are dispersedly arranged on the outer sides of the tops of the two support formworks 1 and are used for blocking the horizontal position of the prefabricated beam 7 during beam assembly. The positioning assembly 2 includes a lateral support frame 21, a horizontal adjustment hydraulic cylinder 23 and a lateral positioning plate 25. The lower end of the lateral support frame 21 is fixed on the support formwork 1, and the upper end extends upward. A lateral support plate 22 is fixed at the top end of the lateral support frame 21. The horizontal adjustment hydraulic cylinder 23 is fixedly installed inside the lateral support plate 22 and is parallel to the support formwork 1. A transfer plate 24 is fixedly installed at the output end of the horizontal adjustment hydraulic cylinder 23. Guide rods 221 that are slidably connected are inserted on both sides inside the lateral support plate 22. The end of the guide rod 221 is fixedly connected to the transfer plate 24. The lateral positioning plate 25 is fixed on the side of the transfer plate 24 away from the lateral support plate 22. A pressure sensor 241 is fixedly installed on the side wall of the transfer plate 24 adjacent to the lateral positioning plate 25. The force-receiving end of the pressure sensor 241 is fixedly connected to the lateral positioning plate 25;

[0042] It should be noted that: through the setting of the positioning assembly 2, during the beam assembly process, when the prefabricated beam 7 is placed on the supporting assembly 3 by an external lifting device, the horizontal adjustment hydraulic cylinder 23 in the positioning assembly 2 can be controlled to work as needed, so as to drive the lateral positioning plate 25 at the corresponding end to move. When the lateral positioning plate 25 is adjusted to the required position, it can block and limit the outer wall of the lifted beam. Thus, when the side wall of the moving beam abuts against the adjusted lateral positioning plate 25 during assembly, the pressure sensor 241 will monitor the acting force when the lateral positioning plate 25 abuts against the beam. At this time, the controller at the terminal, while detecting the change in the value of the pressure sensor 241, controls the alarm at the terminal to give an alarm prompt. At this time, the driver of the lifting device can stop controlling the lifting device, so that the beam is stable on the supporting assembly 3, and thus the horizontal position of the beam can be positioned. Then, the remaining horizontal adjustment hydraulic cylinders 23 in the positioning assembly 2 can be controlled to drive the corresponding lateral positioning plates 25 to move, so that multiple lateral positioning plates 25 can block and limit multiple side walls of the beam. Therefore, the beam can be blocked and limited in the horizontal direction, and the phenomenon that the adjusted beam moves randomly in the horizontal plane can be avoided.

[0043] In the embodiment of the present invention, please refer to Figures 1 to 8, a supporting component 3 for supporting the assembly crossbeam is provided at the top of the supporting template 1. The supporting component 3 includes a jacking hydraulic cylinder 31 and a supporting plate 32. A plurality of jacking hydraulic cylinders 31 are provided and evenly distributed above the supporting template 1. The supporting plate 32 is fixedly installed at the tops of the plurality of jacking hydraulic cylinders 31, and an assembly hole 10 is opened at the position of the supporting plate 32 corresponding to the installation hole 9. The jacking hydraulic cylinders 31 are symmetrically distributed on both sides of the assembly hole 10. Symmetrically distributed mounting frames 321 are fixedly erected on both sides of the top of the supporting plate 32. A plurality of longitudinally guiding rollers 322 that are evenly distributed and rotatably connected are erected inside the mounting frames 321, and the outer walls of the longitudinally guiding rollers 322 are located above the tops of the mounting frames 321. A transfer frame 33 is fixedly installed on the top of the supporting plate 32. Vertically adjusting hydraulic cylinders 331 are fixedly installed on both sides of the top of the transfer frame 33. The tops of the plurality of vertically adjusting hydraulic cylinders 331 are installed with a top frame 332 fixedly connected therewith. A plurality of horizontally guiding rollers 333 that are evenly distributed and rotatably connected are erected inside the top frame 332, and the outer walls of the horizontally guiding rollers 333 are located above the tops of the top frame 332. A plurality of mounting frames 321 are evenly distributed between two adjacent horizontally guiding rollers 333, and the distance between two adjacent horizontally guiding rollers 333 is greater than the outer wall specification of the mounting frame 321.

[0044] It should be noted that: by erecting the mounting frame 321 between two adjacent horizontally guiding rollers 333, during the use of the support, when the vertical adjusting cylinder works, the top frame 332 and the horizontally guiding rollers 333 can move smoothly along the outer walls of the longitudinally guiding rollers 322 and the mounting frame 321, so that the horizontally guiding rollers 333 or the longitudinally guiding rollers 322 can be adjusted to abut against the bottom of the crossbeam as required. Furthermore, during the use process, when the external lifting device pulls the crossbeam horizontally or longitudinally, the crossbeam can move more stably on the supporting component 3.

[0045] Therefore, when using this device to assemble the prefabricated crossbeam, compared with simply lifting and moving, the phenomenon that the suspended crossbeam moves randomly in the horizontal plane can be reduced, and thus the movement of the crossbeam in the horizontal direction can be more stable during the assembly process.

[0046] In the embodiment of the present invention, please refer to Figures 1 to 8 , the support frame 4 is fixedly installed on the top of the crossbeam by bolts. A projection spotlight 41 is fixedly installed on the inner top of the support frame 4, and a lifting hanging ring 42 is fixedly installed on the top of the support frame 4. Mounting plates 5 fixedly connected are installed on the tops of both supporting plates 32, and cameras 51 fixedly connected are installed on the opposite surfaces of both mounting plates 5.

[0047] It should be noted that: through the setting of the projection spotlight 41, during the assembly process, after the positioning of the cross beam is completed, the projection spotlight 41 can be turned on, and then the light at the projection position of the projection spotlight 41 can be observed through the camera 51. When the position of the cross beam is aligned with the position of the main pier, the light at the projection position can smoothly be located at the top of the docking rod on the top of the main pier, so as to realize the monitoring and positioning of the position of the adjusted main pier; and through the setting of the lifting loop 42, after the use of the projection spotlight 41 is completed, an external lifting device can be connected to the lifting loop 42, and then it is convenient to disassemble the support frame 4 from the cross beam.

[0048] In an embodiment of the present invention, please refer to Figures 1 to 8 , extension plates 11 are fixedly installed at the tops of both support templates 1, and through holes having the same size and shape as the mounting holes 9 are provided at the positions of the two extension plates 11 corresponding to the mounting holes 9; multiple groups of positioning components are evenly dispersed outside the extension plates 11, the bottom of each lateral support frame 21 is fixedly connected to the extension plate 11 by bolts, and multiple lateral support frames 21 are all inclined outward; the bottoms of the jacking hydraulic cylinders 31 are all fixed on the top surface of the extension plate 11. Alignment grooves 12 are provided inside the support templates 1, and the two support templates 1 are fixedly installed on the outer wall of the main pier casting form 8 by bolts.

[0049] It should be noted that: through the setting of the extension plate 11, during the use process, the extension plate 11 can increase the area of the support template 1, and then the support template 1 can smoothly support the positioning component 2. And by providing the alignment groove 12 on the inner wall of the support template 1, during the installation process, when the support template 1 is sleeved and installed towards the outer wall of the main pier, the inner wall of the alignment groove 12 can smoothly abut against the outer wall of the reinforcing rib on the outer wall of the main pier casting form, so that the support template 1 can smoothly be sleeved on the outer wall of the main pier casting form, and then the support template 1 can smoothly support structures such as the positioning component 2 and the supporting component 3 in the later stage.

[0050] The working principle of the high-altitude beam assembly support device provided by the present invention is as follows: When using this device, the support template 1 in this device can be installed on the outer wall of the casting formwork during the casting of the main pier. Then, according to needs, the positioning component 2 and the supporting component 3 can be installed on the extension plate 11 at the top of the support template 1. Next, the installation frame 321 can be installed on the top of the assembled beam 7. Furthermore, during assembly, an external hoisting device can be connected to the top of the assembled beam 7. Then, through the hoisting device, the assembled beam 7 can be lifted and moved towards the top of the main pier 6. When the assembled beam 7 moves above the main pier 6 and the bottom of the assembled beam 7 abuts against the lateral guide roller 333 in the supporting component 3, the placed assembled beam 7 will shift towards one side at the top of the main pier 6. During this process, the horizontal adjustment hydraulic cylinder 23 in the positioning component 2 that is far from the side wall of the assembled beam 7 can be controlled to work, so that the corresponding lateral positioning plate 25 can be moved to the position required for beam alignment. After the adjustment of the lateral positioning plate 25 is completed, the hoisting device can be controlled to pull the assembled beam 7. At this time, the beam that abuts against the lateral guide roller 333 or the longitudinal guide roller 322 will move towards the corresponding lateral positioning plate 25 on the lateral guide roller 333 or the longitudinal guide roller 322. During this process, the lateral guide roller 333 or the longitudinal guide roller 322 can make the movement of the beam more stable and convenient. Therefore, through the support of the lateral guide roller 333 or the longitudinal guide roller 322, the random displacement of the beam in the horizontal direction when the hoisting device directly hoists and moves the beam can be reduced, and thus the adjustment drive of the hoisting device for the beam can be made more stable.

[0051] When the side wall of the moving beam abuts against the adjusted lateral positioning plate 25, the pressure sensor 241 will monitor the force when the lateral positioning plate 25 abuts against the beam. At this time, the terminal controller detects the value change of the pressure sensor 241 and controls the terminal alarm to give an alarm prompt. At this time, the driver of the lifting device can stop operating the lifting device to stabilize the assembled beam 7 on the supporting component 3, and then control the remaining horizontal adjustment hydraulic cylinders 23 in the positioning component 2 to drive the corresponding lateral positioning plate 25 to move, so that the lateral positioning can be completed. The outer wall of the assembled crossbeam 7 is shielded and positioned; after the horizontal position of the assembled crossbeam 7 is adjusted, the projection spotlight 41 at the top of the support frame 4 can be controlled to work, and the working projection spotlight 41 will pass through the assembled crossbeam 7 to project toward the top of the main pier 6. During this process, the staff can watch the position of the projection light at the top of the main pier 6 through the camera 51. When the projection light passes through the docking hole in the crossbeam and shines on the top of the docking rod at the top of the main pier 6, the docking hole in the surface crossbeam and the docking rod in the main pier are in the same vertical plane, thereby ensuring the accuracy of the crossbeam position adjustment. At this point, the staff can control the jacking hydraulic cylinder 31 to shrink, and the shrinking jacking hydraulic cylinder 31 can drive the crossbeam to fall in the vertical direction until the alignment rod at the top of the main pier 6 is inserted into the alignment hole in the assembled crossbeam 7, and the assembly of the assembled crossbeam 7 can be completed.

[0052] The embodiment provides a method for using a high-altitude crossbeam assembly support device, which is used in the assembly of a prefabricated crossbeam 7 and a main pier 6 erected at high altitude. The prefabricated crossbeam 7 and the main pier 6 are perpendicular to each other. The device is installed at the connection between the main pier 6 and the prefabricated crossbeam 7, and is used to support and adjust the assembly of the prefabricated crossbeam 7. The specific use of the device includes the following steps:

[0053] S1. After the main pier 6 is cast and before the assembled crossbeam 7 is installed, the support formwork 1 in the support device is first fixed on the outer wall of the formwork built during the casting of the main pier by bolts;

[0054] S2, then fix the positioning component 2 and the supporting component 3 on the top of the supporting template 1 in sequence;

[0055] S3, then the support frame 4 can be fixedly installed on the top of the beam to be assembled, and the assembled beam 7 can be connected to the external lifting device;

[0056] S4. After the device is assembled, the electrical components in the device can be electrically connected to the controller of the terminal;

[0057] S5, at this time the staff can control the lifting device to move the assembled beam 7 to the supporting assembly 3;

[0058] After the preliminary positioning of the prefabricated cross beam 7 is completed, the lateral positioning plate 25 in the positioning assembly 2 can be controlled as needed, so that the lateral positioning can block the trajectory of the laterally moving prefabricated cross beam 7, enabling the prefabricated cross beam 7 to move to the required position as needed;

[0059] After the adjustment of the positioning assembly 2 is completed, the lifting device can be controlled to pull the cross beam, so that the prefabricated cross beam 7 moves horizontally in the corresponding direction. During this process, the longitudinal guide roller 322 or the transverse guide roller 333 in the supporting assembly 3 can be controlled to abut against the bottom of the cross beam as needed, so as to support and guide the moving cross beam and improve the moving stability of the cross beam;

[0060] During the movement of the cross beam, the pressure sensor 241 in the positioning assembly 2 can accurately control the moving position of the prefabricated cross beam 7 by detecting the pressure value of the lateral positioning plate 25;

[0061] After the horizontal movement of the position of the prefabricated cross beam 7 is completed, the projection spotlight 41 can be controlled to irradiate to further detect the alignment state of the prefabricated cross beam 7;

[0062] After monitoring the position of the prefabricated cross beam 7 is completed, the jacking hydraulic cylinder 31 in the supporting assembly 3 can be controlled to contract, so that the prefabricated cross beam 7 moves downward until the prefabricated cross beam 7 is erected on the top of the main pier, and the assembly process of the prefabricated cross beam 7 can be completed.

[0063] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
