Description

Technical Field

[0001] This invention relates to the field of steel pipe construction technology for arch bridges, specifically to a steel pipe pier positioning support structure for the installation of steel box arch bridges. Background Technology

[0002] An arch bridge is a bridge in a vertical plane that uses an arch as the main load-bearing structural component. The vertical load on an arch bridge is transferred to the arch platform through the curved arch. Originally, it was not used for landscaping, but for the purpose of flood discharge and navigation under the bridge in engineering. Because its bridge body is curved, it was often called a curved bridge in ancient times.

[0003] With the continuous development of urbanization, more and more large bridges are being built. Arch bridges not only have a large span capacity and can meet the load-bearing requirements, but they are also very beautiful in appearance. When conditions permit, building arch bridges is often an economical and reasonable choice. In the construction of arch bridges, the installation and positioning of steel arches is quite complex. The installation accuracy of steel beams and steel arches has a great impact on the structural stress and service life of the bridge. Therefore, the installation and positioning of steel arch bridges needs to be given special attention.

[0004] The traditional positioning and installation method involves directly setting up supports on the bracket, using cranes or other equipment to coarsely adjust the steel arch or beam segments, then setting up pads, and finally using heavy-duty jacks to finely adjust the height. This method involves a lot of high-altitude work due to the use of cranes for coarse adjustment, and is difficult to adjust due to the influence of high-altitude swaying. To ensure accuracy, a lot of manpower and resources are required, which can easily affect the construction schedule. Therefore, the existing positioning method is still inconvenient in practical use and needs to be improved in terms of efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a steel pipe pier positioning support structure for the installation of steel box arch bridges, which improves the positioning and installation efficiency and accuracy of steel beams and arches, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel pipe pier positioning support structure for steel box arch bridge installation, comprising a support body, wherein two sets of positioning components are provided on the support body;

A fixed shaft is rotatably connected to the inner wall of the U-shaped plate. Two fixed gears are fixedly connected to the shaft arms of the fixed shaft. The teeth of the two fixed gears mesh with the teeth of the two internal gear plates. A spur gear cylinder is fixedly connected to the shaft arms of the fixed shaft. A rack is vertically slidably connected to the inner wall of the base plate. The teeth of the rack mesh with the teeth of the spur gear cylinder. A synchronizing rod is fixedly connected to the inner wall of the U-shaped plate. A groove is provided on the inner wall of the rack for the synchronizing rod to pass through and slidably connect with it.

[0015] Each of the fixed-axis arms is rotatably connected to a push rod, and the ends of both push rods are vertically slidably connected to the side wall of the positioning plate.

[0016] Optionally, the auxiliary component includes:

[0017] Box 2 is fixedly connected to the surface of the base plate. A drive shaft is rotatably connected to the inner wall of box 2. Two discs are fixedly connected to the shaft arm of the drive shaft. Sliding rods are slidably connected to the inner walls of the two discs. Springs are fixedly connected to the ends of the two sliding rods. The ends of the two springs are fixedly connected to the inner walls of the two discs respectively. Arc-shaped blocks are fixedly connected to the ends of the two sliding rods. The two arc-shaped blocks are respectively connected to the shaft arms of the two main shafts through pulley assemblies.

[0018] Optionally, both ends of the drive shaft are fixedly connected to a rotating wheel, and the surfaces of both rotating wheels are provided with anti-slip textures.

[0023] Optionally, the end of the movable threaded rod is provided with a knob, and the surface of the knob is provided with anti-slip texture.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] I. This invention, through the setting of the support body and two positioning components, enables the equipment to simultaneously meet the positioning and installation of steel beams and steel arches. The setting of the positioning components greatly shortens the installation cycle and achieves the effect of improving installation efficiency.

[0026] Second, this invention, through the cooperation of the main shaft, the moving threaded rod and the fixed gear, enables the positioning plate to drive the steel pipe fittings to be positioned and supported, first at a certain speed until they slightly exceed the position of the adjacent steel pipe segments, and then slowly reset until the positioning calibration of the adjacent segments is completed. This can greatly improve the accuracy and practicality of the positioning process and improve the efficiency of engineering construction.

[0027] Third, through the cooperation of structures such as disc, sliding rod group and spring group, the present invention enables the positioning plate to drive the steel pipe component to be positioned and supported in the initial positioning process, and the displacement speed will be continuously reduced. In this way, the accuracy can be further improved in the initial positioning process, and the steel pipe component to be positioned and supported will not exceed the position of the workpiece on the adjacent segment by too much, making the overall practicality stronger.

[0028] This method also allows installers to simply rotate the wheel from a fixed position, further enhancing ease of use.

[0029] Fourth, through the cooperation of the offset rod, the anti-offset threaded rod, and the motor, the present invention allows the installer to rotate the offset rod and, in conjunction with the motor, place the hoisted workpiece stably on the support plate when positioning and installing the steel arch. This further increases efficiency and makes the device more practical. Attached Figure Description

[0040] 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.

[0041] Example 1:

[0042] Please see Figures 1 to 9 The present invention provides a technical solution: a steel pipe pier positioning support structure for steel box arch bridge installation, including a support body 1, on which two sets of positioning components are provided;

[0043] The positioning assembly includes a base plate 2, which is fixedly connected to the bracket body 1. A positioning plate 3 is slidably connected to the surface of the base plate 2, and a support plate 4 is rotatably connected to the surface of the positioning plate 3. A control component is provided inside the positioning plate 3.

[0044] The positioning component also includes a moving part, which is set on the base plate 2. The moving part enables the positioning plate 3 to move horizontally, and the speed changes accordingly with the direction of displacement.

[0045] The positioning assembly also includes auxiliary components, which are connected to the moving components via a transmission mechanism. By providing these auxiliary components, the positioning plate 3 can also exhibit speed variation when moving horizontally without changing its direction.

[0046] Both positioning components are equipped with mating parts, and the upper positioning component is also equipped with two sets of anti-displacement parts.

[0047] More specifically, in this embodiment: First, the support body 1 is erected under the arch bridge. According to the design drawings, two sets of positioning components are respectively set at the required installation positions of the steel beam and the steel arch. When installing the steel beam, it is transported along the construction axis of the arch bridge so that it is positioned on the matching support plate 4. When installing the steel arch, it is hoisted and placed on the matching support plate 4 to complete the initial position control. After the steel pipe structure is placed, the control component is activated. Through the setting of the control component, the support plate 4 is deflected so that the adjacent segments are on the same horizontal line. Then, the positioning component is controlled. By driving the auxiliary component, the positioning plate 3 is moved horizontally, and the speed is gradually reduced during the movement. This maintains a certain accuracy in the initial positioning of the steel pipes of the adjacent segments. Then, by controlling the moving component, the positioning plate 3 is moved in the opposite direction at a slower speed in the horizontal direction to accurately align it. In this way, efficiency is improved, operation is facilitated, and the accuracy of installation is guaranteed, achieving the purpose of precise positioning.

[0048] Example 2, based on the above examples:

[0049] Please see Figure 1 , Figure 2 and Figure 8 The control component in Embodiment 1 is disclosed as follows: the control component includes two hydraulic rods 5, both of which are fixedly connected to the inner wall of the positioning plate 3, and the hydraulic heads of both hydraulic rods 5 are rotatably connected to the bottom surface of the support plate 4.

[0050] More specifically, in this embodiment: by manipulating the two hydraulic rods 5, the support plate 4 can be deflected, thereby causing the steel pipe material placed above to deflect, so that it can be kept on the same horizontal line as the installation material of the adjacent segment.

[0051] Example 3, based on the above examples:

[0052] Please see Figures 3 to 6The moving component in Embodiment 1 is disclosed as follows: the moving component includes a housing 6, which is slidably connected to the surface of the base plate 2. Two main shafts 7 are rotatably connected to the inner wall of the housing 6. Internal gear plates 8 are fixedly connected to the shaft arms of both main shafts 7. Gears 9 are fixedly connected to the inner walls of both internal gear plates 8. A movable threaded rod 10 is threadedly connected to the inner wall of the housing 6. A U-shaped plate 11 is rotatably connected to the arm of the movable threaded rod 10. A fixed shaft is rotatably connected to the inner wall of the U-shaped plate 11. 12. The shaft arm of the fixed shaft 12 is fixedly connected to two fixed gears 13. The teeth of the two fixed gears 13 mesh with the teeth of the two internal gear plates 8 respectively. The shaft arm of the fixed shaft 12 is fixedly connected to a straight tooth cylinder 14. The inner wall of the base plate 2 is vertically slidably connected to a rack row 15. The teeth of the rack row 15 mesh with the teeth of the straight tooth cylinder 14. The inner wall of the U-shaped plate 11 is fixedly connected to a synchronizing rod 16. The inner wall of the rack row 15 is provided with a groove 34 for the synchronizing rod 16 to pass through and slide with it.

[0053] The shaft arms of the fixed shaft 12 are rotatably connected to push rods 17, and the ends of the two push rods 17 are vertically slidably connected to the side wall of the positioning plate 3.

[0054] More specifically, in this embodiment: by rotating the main shaft 7, the connected internal gear plate 8 is rotated. The rotation of the internal gear plate 8 causes the meshing fixed gear 13 to rotate, which in turn causes the fixed shaft 12 to rotate. The rotation of the fixed shaft 12 causes the spur gear cylinder 14 to rotate. Through the transmission of the spur gear cylinder 14, it engages with the rack and pinion 15 and moves closer to the positioning plate 3. The horizontal displacement of the fixed shaft 12, through the transmission of the two push rods 17, pushes the positioning plate 3 to move, so that the mounting part moves horizontally until it slightly exceeds the required positioning position.

[0055] Subsequently, by rotating the movable threaded rod 10, the U-shaped plate 11 moves vertically upward. This vertical movement of the U-shaped plate 11, through the transmission of the fixed shaft 12, causes the two fixed gears 13 to move vertically upward. Taking a single fixed gear 13 as an example, this disengages the teeth of the internal gear plate 8 from the teeth of the fixed gear 13, while the teeth of the fixed gear 13 engage with the teeth of the gear 9. Continuing to rotate the main shaft 7 in the same direction, through the transmission of the gear 9, causes the fixed gear 13 to rotate in the opposite direction. This, through the transmission of the two push rods 17, allows the positioning... Plate 3 moves horizontally in the opposite direction. At the same time, due to the different transmission ratios of the internal gear plate 8 and gear 9 to the fixed gear 13, the rotational speed of the fixed gear 13 will be greatly reduced. That is, the positioning plate 3 will move horizontally in the opposite direction at a slower speed. In this way, the steel pipe fittings that need to be positioned and supported can be driven by the positioning plate 3 to be positioned at a certain speed first, and then slowly reset to complete the positioning calibration. This operation process makes it more convenient for workers to operate in practice. Compared with the traditional method, there is no need to check whether the positioning is completed multiple times. The accuracy and practicality of positioning are greatly improved.

[0056] It is worth noting that during this process, the box 6 slides along the surface of the base plate 2.

[0057] Example 4, based on the above examples:

[0058] Please see Figures 3 to 7 The auxiliary components in Embodiment 1 are disclosed as follows: the auxiliary components include: a second housing 18, which is fixedly connected to the surface of the base plate 2. A drive shaft 19 is rotatably connected to the inner wall of the second housing 18. Two discs 20 are fixedly connected to the shaft arm of the drive shaft 19. A sliding rod assembly 21 is slidably connected to the inner wall of each of the two discs 20. A spring assembly 22 is fixedly connected to the end of each of the two sliding rod assemblies 21. The ends of the two spring assemblies 22 are respectively fixedly connected to the inner wall of the two discs 20. An arc-shaped block assembly 23 is fixedly connected to the end of each of the two sliding rod assemblies 21. The two arc-shaped block assemblies 23 are respectively connected to the shaft arm of the two main shafts 7 through a pulley assembly 24.

[0059] More specifically, in this embodiment: In actual use, the worker can rotate the drive shaft 19 to synchronously drive the disc 20 to rotate. Thus, through the rotation of the disc 20, the slide bar assembly 21 makes circumferential displacement around the drive shaft 19. At this time, through the transmission of the pulley assembly 24, the main shaft 7 can be rotated. As the main shaft 7 rotates and its distance from the disc 20 increases, the slide bar assembly 21 will slide along the inner wall of the disc 20, causing the spring assembly 22 to be compressed. That is, through the setting of the spring assembly 22, the pulley assembly 24 is always kept in a tensioned state.

[0060] Meanwhile, as the distance between the main shaft 7 and the disk 20 increases, the transmission ratio between the main shaft 7 and the drive shaft 19 changes synchronously. At this time, while the drive shaft 19 maintains a certain speed, the speed of the main shaft 7 will continuously decrease. That is, during this process, the speed at which the positioning plate 3 moves will continuously decrease.

[0061] The above process can further improve the accuracy during the initial positioning process, and the steel pipe fittings required for positioning support will not exceed the position of the workpiece on the adjacent segment by too much, making the overall practicality stronger.

[0062] Meanwhile, in actual use, the above process requires two installers to work together, with one rotating the drive shaft 19 from a fixed position while the other assists, greatly improving ease of use.

[0063] Example 5, based on the above examples:

[0064] Please see Figure 3 and Figure 5 Both ends of the drive shaft 19 are fixedly connected to a rotating wheel 25, and the surfaces of the two rotating wheels 25 are provided with anti-slip textures.

[0065] With the rotating wheel 25, the installer can rotate the drive shaft 19 by rotating the wheel 25. The anti-slip texture prevents the installer from slipping during this operation.

[0066] Please see Figure 2 and Figure 9 The anti-deviation component includes: a first deviation rod 26, the end of which is rotatably connected to the surface of the base plate 2, a sliding plate 27 slidably connected to the inner wall of the first deviation rod 26, a motor 28 fixedly connected to the surface of the sliding plate 27, an anti-deviation threaded rod 29 fixedly connected to the output end of the motor 28, the arm of the anti-deviation threaded rod 29 being threadedly connected to the inner wall of the first deviation rod 26, a second deviation rod 30 fixedly connected to the end of the anti-deviation threaded rod 29, and a rubber block 31 provided at the end of the second deviation rod 30.

[0067] During the installation of steel pipes in the steel arch segment, the supporting workpiece is prone to swaying in the air due to the hoisting and conveying method. The installer can rotate the offset rod 26 to align its end with the workpiece, and then start the motor 28 to rotate the anti-offset threaded rod 29. This rotation, through the transmission of the sliding plate 27, causes the motor 28 and the anti-offset threaded rod 29 to move synchronously, causing the offset rod 30 to extend until the rubber block 31 contacts the workpiece. At this point, the hoisted workpiece is constrained, and the installer can then control the offset rod 26 and the motor 28 to place it stably on the support plate 4. This further improves the ease of use and makes the device more practical.

[0068] Please see Figure 3 and Figure 4 The cooperating components include: two signal display groups 32, which are respectively fixedly connected to both sides of the support plate 4.

[0069] By setting up the signal display group 32, the support component can cooperate with the signal display group 32 on the adjacent steel pipe section after complete positioning and calibration. When the signal is aligned, the positioning can be regarded as successful. The working principle of the signal display group 32 can be the same as that of the laser transmitter and receiver.

[0070] Furthermore, please refer to Figures 3 to 5 The end of the movable threaded rod 10 is provided with a knob 33. The surface of the knob 33 is provided with anti-slip texture. By turning the knob 33, the worker can make the movable threaded rod 10 rotate.

[0071] Working principle: When using the steel pipe pier positioning support structure for the steel box arch bridge, the support body 1 is first erected under the arch bridge. According to the design drawings, the two sets of positioning components are set at the required installation positions of the steel beam and the steel arch. When installing the steel beam, it is transported along the construction axis of the arch bridge so that it is positioned on the matching support plate 4. When installing the steel arch, it is hoisted and placed on the matching support plate 4 to complete the initial position control.

[0072] Workers can rotate the rotating wheel 25, which will drive the disc 20 to rotate synchronously through the drive shaft 19. At this time, the main shaft 7 will rotate through the transmission of the slide bar group 21 and the pulley assembly 24, which will cause the support plate 4 on the positioning plate 3 to move horizontally with decreasing speed. During this process, the pulley assembly 24 will always be kept taut through the spring group 22 until the installed steel pipe is driven to exceed the position of the adjacent section.

[0073] Then, rotating the movable threaded rod 10 causes the U-shaped plate 11 to move vertically upwards, thereby disengaging the teeth of the internal gear plate 8 from the teeth of the fixed gear 13. The teeth of the fixed gear 13 then engage with the teeth of the gear 9, causing the positioning plate 3 to move horizontally in the opposite direction at a relatively slow speed. This drives the steel pipe component that needs to be positioned and supported to first be positioned at a certain speed, and then slowly reset until the positioning calibration is completed. In this way, the positioning and installation of a section of steel pipe can be completed.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
