[0003] In current technology, before assembling the arch ribs, workers need to install steel partition column supports. These supports are located at both ends of each steel arch rib segment, along with the arch feet. During construction, a crane is used to lift the steel arch ribs above the steel partition column supports. The arch ribs and arch feet are then positioned and supported by the supports. The arch ribs and arch feet are then installed, and the arch ribs are assembled sequentially. Finally, the arch ribs are joined together in the middle, thus completing the arch rib assembly.

[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.

[0030] Specific implementation examples are given below.

[0031] Please see Figure 1-3As shown, a steel arch rib assembly and adjustment device includes a lifting hydraulic cylinder 11; the output end of the lifting hydraulic cylinder 11 is fixedly connected to a base 12; a support seat 14 is slidably connected to the top side of the base 12 via a slide rail; lateral hydraulic cylinders 13 are fixedly connected to both sides of the base 12; the output end of the lateral hydraulic cylinder 13 is fixedly connected to the side wall of the support seat 14; an adjustment plate 15 is provided in the middle of the support seat 14; an adjustment seat 16 is fixedly connected to the middle of the adjustment plate 15; a drive wheel 17 is rotatably connected to the top of the adjustment seat 16; a reduction motor 18 is fixedly connected to the top of the adjustment seat 16; the output end of the reduction motor 18 is fixedly connected to the drive wheel 17; before construction, the lifting hydraulic cylinder 11 is installed and fixed on the top of the steel partition column support. In this embodiment of the invention, during construction, the workers hoist the steel arch rib above the two steel partition column supports, and then hoist it to the top of the drive wheel 17. The drive wheels 17 at the top of the frame support both ends of the steel arch rib. Then, by controlling the lifting hydraulic cylinders 11, the steel arch rib is moved upwards to adjust its height. The lateral hydraulic cylinders 13 move the support base 14 to adjust the steel arch rib laterally. Simultaneously, by controlling the different extension heights of the two lifting hydraulic cylinders 11, the steel arch rib can be tilted to adjust its tilt angle. After adjustment, the reduction motor 18 is controlled, driving the drive wheels 17 to rotate. The rotating drive wheels 17 push the steel arch rib to align with the already installed steel arch rib, thus completing the splicing of the steel arch rib. Based on the above setup, the steel arch rib is placed on the drive wheels 17, and adjusted by the lifting hydraulic cylinders 11 and lateral hydraulic cylinders 13. This reduces the impact of external wind on the splicing of the steel arch rib, facilitating the splicing process.

[0032] Furthermore, such as Figure 1-3As shown, a sliding groove is formed in the middle of the support base 14; the adjusting plate 15 is slidably connected to the sliding groove; the cross-section of the adjusting plate 15 is designed with a fan-shaped annular structure; multiple racks 22 are fixedly connected to the side of the adjusting plate 15 away from the adjusting base 16; a servo motor 23 is fixedly connected to the rear side of the support base 14; a rotating shaft 21 is fixedly connected to the output end of the servo motor 23; the rotating shaft 21 is rotatably connected to the support base 14; gears are fixedly connected to the surface of the rotating shaft 21 at positions corresponding to the racks 22; the gears mesh with the racks 22; a fixing component is provided on the adjusting plate 15; the fixing component is used for... The steel arch ribs are fixed. During construction, some types of steel arch ribs are inclined. Therefore, during the splicing and installation of the steel arch ribs, it is necessary to change the steel arch ribs from a vertical state to an inclined state. In this embodiment of the invention, the servo motor 23 is controlled. The servo motor 23 is equipped with a reducer. Then, the servo motor 23 drives the rotating shaft 21 and the gear to rotate, thereby driving the rack 22 and the adjusting plate 15 to slide in the slide groove, thereby causing the steel arch rib on the drive wheel 17 to tilt. The fixing component fixes the steel arch rib, thereby adjusting the posture of the steel arch rib, thus improving the scope of application and applicability.

[0033] Furthermore, such as Figure 1-2 As shown in Figure 4, the fixing assembly includes a fixing frame 31; a pair of fixing frames 31 are fixedly connected to the top of the adjusting plate 15; a fixing hydraulic cylinder 32 is fixedly connected to the top of the fixing frame 31; a first piston cylinder 34 is fixedly connected to the output end of the fixing hydraulic cylinder 32; a fixing cover 33 is fixedly connected to the end of the first piston cylinder 34 away from the fixing hydraulic cylinder 32; during construction, after the steel arch rib is placed on the drive wheel 17, the fixing hydraulic cylinder 32 is activated. The initial state of the fixing hydraulic cylinder 32 is the retracted state. The fixing hydraulic cylinder 32 pushes the fixing cover 33 to contact the surface of the steel arch rib. The fixing hydraulic cylinders 32 on both sides fix the steel arch rib from both sides, thereby reducing the movement of the steel arch rib during the adjustment of the position of the steel arch rib. At the same time, it is convenient to fix the steel arch rib with a vertically elongated cross section, thus improving the applicability.

[0034] Furthermore, such as Figure 1-2As shown in Figure 4, a piston rod 41 is slidably connected to the middle of the first piston cylinder 34; a wheel frame 42 is rotatably connected to one end of the piston rod 41 outside the first piston cylinder 34; a torsion spring is installed at the rotatable connection between the wheel frame 42 and the piston rod 41; the wheel frame 42 is located inside the fixed cover 33; a guide wheel is rotatably connected to the wheel frame 42; a through hole is opened in the middle of the piston rod 41; a sealing rod 43 is slidably connected to the middle of the through hole; the sealing rod 43 is rotatably connected to the inner wall of the first piston cylinder 34; the wheel frame 42 is fixedly connected to the end of the sealing rod 43; and an opening is provided on the sealing rod 43. A first through groove 44 is provided; a second through groove 45 is provided at the corresponding position of the through hole and the first through groove 44; a return spring is provided in the rodless chamber of the first piston cylinder 34; during the process of fixing the steel arch rib by the fixing cover 33, the guide wheel will first contact the steel arch rib, and then under the squeezing action, the guide wheel, wheel frame 42 and piston rod 41 will move towards the first piston cylinder 34, the return spring will be compressed, the first piston cylinder 34 will be filled with hydraulic oil, and then the hydraulic oil in the rodless chamber of the first piston cylinder 34 will enter the rod chamber of the first piston cylinder 34 from the first through groove 44 and the second through groove 45. When the drive wheel 17 drives the steel arch ribs for splicing, it is necessary to first control the fixed hydraulic cylinder 32 to separate the fixed cover 33 from the steel arch ribs. Then, the return spring continuously pushes out the piston rod 41, and the guide wheel remains in contact with the surface of the steel arch ribs. In the prior art, an anti-rotation mechanism is installed between the hydraulic cylinder and the piston rod 41. In this embodiment of the invention, an anti-rotation mechanism is installed between the first piston cylinder 34 and the piston rod 41, making it difficult for the piston rod 41 to rotate with the first piston cylinder 34. The guide wheel is kept vertical by the torsion spring by default. During the process of the drive wheel 17 pushing the steel arch ribs for splicing, friction is used to keep the guide wheel in a vertical position. The guide wheel drives the wheel frame 42 to deflect, which in turn drives the sealing rod 43 to deflect, thus preventing the first through groove 44 and the second through groove 45 from connecting, thereby preventing the hydraulic oil from flowing. This fixes the piston rod 41, the wheel frame 42, and the guide wheel. By setting the guide wheel to contact the steel arch rib, the steel arch rib can be guided from both sides during the process, reducing the swaying of the steel arch rib during movement and improving the positioning and splicing accuracy. After the splicing is completed, the fixed hydraulic cylinder 32 retracts, causing the guide wheel to reset and separate from the steel arch rib. Then, the wheel frame 42 rotates and resets under the action of the torsion spring.

[0035] Furthermore, such as Figure 3 and 5As shown, multiple sets of second piston cylinders 51 are fixedly connected to the upper part of the drive wheel 17; the multiple sets of second piston cylinders 51 are arranged in a circular array on the drive wheel 17; a guide rod 52 is slidably connected to the middle of the second piston cylinder 51; an elastic plate 53 is fixedly connected to one end of the guide rod 52 away from the drive wheel 17; a buffer spring is fixedly connected between the second piston cylinder 51 and the guide rod 52; during use, when the steel arch rib is lowered into the drive wheel 17, the elastic plate 53 is pressed under the steel arch rib, causing it to bend and deform to fit against the steel arch rib, and then the guide rod 52 slides into the second piston cylinder 51, and the other elastic plates 53 in contact with the steel arch rib will also bend and deform accordingly. By relying on the above arrangement, the contact area between the drive wheel 17 and the lower surface of the steel arch rib can be increased, thereby improving the fixing effect of the steel arch rib and reducing the possibility of the steel arch rib slipping off the drive wheel 17, so that the drive wheel 17 can stably control the splicing of the steel arch rib, and at the same time reduce the possibility of the steel arch rib sliding under its own weight and causing collisions between the steel arch ribs.

[0036] Furthermore, such as Figure 5 and 7As shown in Figure -8, a piston plate 61 is fixedly connected to the guide rod 52; the piston plate 61 is slidably connected to the second piston cylinder 51; multiple oil holes 63 are arranged in a circular array on the piston plate 61; a sealing ring 62 is slidably connected to the guide rod 52; the sealing ring 62 is located on the side of the piston plate 61 away from the elastic plate 53; a sealing spring is fixedly connected between the sealing ring 62 and the end of the guide rod 52 located in the second piston cylinder 51; multiple grooves 64 are formed on the sealing ring 62 at positions corresponding to the oil holes 63; during use, when the steel arch rib is lowered, the guide rod 52 slides into the second piston cylinder 51, thereby driving the piston plate 61 to slide. The hydraulic oil in the rodless chamber of the second piston cylinder 51 is injected into the rod chamber through the oil holes 63. With the cooperation of the buffer spring, the kinetic energy of the falling steel arch rib is absorbed, playing a role in buffering and shock absorption. At the same time, when the buffer spring drives the guide rod 52 to reset, the hydraulic oil in the rod chamber of the second piston cylinder 51... The oil hole 63 pushes the sealing ring 62, causing the sealing ring 62 to separate from the piston plate 61. In the initial state, under the action of the sealing spring, the sealing ring 62 is in contact with the surface of the piston plate 61, blocking part of the oil hole 63. At the same time, multiple grooves 64 are opened on the sealing ring 62 to prevent it from blocking all the oil holes 63. During the reset process of the guide rod 52, the hydraulic oil pushes the sealing ring 62 to open all the oil holes 63, thereby increasing the reset speed of the piston plate 61 and the guide rod 52. When the guide rod 52 falls, the excess oil holes 63 are closed, reducing the downward movement speed of the guide rod 52 and playing a buffering and damping role. With the above settings, during the rotation of the drive wheel 17, the guide rod 52 located directly above is compressed to the maximum length in the second piston cylinder 51. As the drive wheel 17 continues to rotate, the guide rod 52 will continuously extend out of the second piston cylinder 51. With the above settings, the extension speed of the guide rod 52 can be accelerated to facilitate stable contact with the steel arch rib.

[0037] Furthermore, such as Figure 1-2 As shown in Figures 5-6, a waterproof cover 71 is fixedly connected between the two fixed frames 31; the waterproof cover 71 is located on the side of the drive wheel 17; a water-absorbing cotton tube 72 is fixedly connected to the middle of the waterproof cover 71; the surface of the water-absorbing cotton tube 72 is in contact with the surface of the elastic plate 53; during construction, the steel arch rib bridge is built on the riverbank, where the air humidity is high, causing the surface of the metal elastic plate 53 to easily condense water. In this embodiment of the invention, before construction, the reduction motor 18 drives the drive wheel 17 to rotate once, and then the water-absorbing cotton tube 72 can be used to wipe the surface of the elastic plate 53 to remove the surface dew, thereby increasing the friction with the surface of the elastic plate 53, so as to facilitate driving and fixing the heavy steel arch rib. The waterproof cover 71 covers the surface of the water-absorbing cotton tube 72, thereby reducing the adhesion of dew and moisture to the surface of the water-absorbing cotton tube 72, and making it easier for the water-absorbing cotton tube 72 to stay dry.

[0038] Furthermore, such as Figure 2-3As shown in Figures 5-6, a drying trough is provided on the side of the waterproof cover 71 away from the drive wheel 17; multiple fixed shafts 82 are rotatably connected to both sides of the drying trough near the fixed frame 31; a rubber wheel 83 is fixedly connected to one end of the fixed shaft 82 near the fixed frame 31; an arc-shaped baffle 81 is fixedly connected to the other end of the fixed shaft 82 away from the fixed frame 31; connecting shafts 85 are rotatably connected to both sides of the waterproof cover 71; friction wheels 84 are fixedly connected to the connecting shafts 85; the friction wheels 84 are in contact with the surface of the rubber wheels 83; a belt is installed between the connecting shafts 85 and the drive wheel 17; on sunny days, the drying trough allows for the drying of people... The operator can control the reduction motor 18 to drive the drive wheel 17 to rotate to a certain extent, and then drive the connecting shaft 85 and the friction wheel 84 to rotate under the action of the belt. The friction wheel 84 uses friction to make the rubber wheel 83, the fixed shaft 82 and the arc-shaped baffle 81 rotate, thereby opening the arc-shaped baffle 81, which facilitates the drying of the absorbent cotton tube 72 and keeps the absorbent cotton tube 72 dry. After drying, the operator controls the servo motor 23 to drive the drive wheel 17 to rotate in the opposite direction, thereby closing the arc-shaped baffle 81 and reducing the moisture of the absorbent cotton tube 72 inside the waterproof cover 71.

[0039] Furthermore, such as Figure 6 As shown, an arc-shaped rubber pad 91 is fixedly connected to the side of the arc-shaped baffle 81 near the fixed shaft 82; a reflective strip 93 is fixedly connected to the side of the arc-shaped baffle 81 near the absorbent cotton tube 72; and a sealing strip 92 is fixedly connected to the side of the waterproof cover 71 near the drive wheel 17. In use, the arc-shaped rubber pad 91 is used to improve the fit between the waterproof cover 71 and the elastic plate 53, thereby reducing the inflow of water vapor and rainwater from the gap between the elastic plate 53 and the waterproof cover 71, which could cause the absorbent cotton tube 72 to become damp. The sealing strip 92 is used to improve the sealing effect between the arc-shaped baffle 81 and the reflective strip 93 can reflect sunlight on the arc-shaped baffle 81, thereby facilitating sunlight to enter the interior of the waterproof cover 71 and keeping the absorbent cotton tube 72 dry.

[0040] Furthermore, such as Figure 2 As shown, a plurality of first pulleys 101 are rotatably connected to the side of the slide away from the drive wheel 17; a plurality of second pulleys 102 are rotatably connected to the bottom of the support base 14; in use, by setting the first pulleys 101, the friction of the adjusting plate 15 sliding in the slide can be reduced, thereby facilitating the servo motor 23 to control the adjusting plate 15 to rotate; by setting the second pulleys 102, the friction of the sliding between the support base 14 and the base 12 can be reduced, facilitating the pushing and adjustment by the lateral hydraulic cylinder 13.

[0041] Working principle: Before construction, the lifting hydraulic cylinder 11 is installed and fixed on the top of the steel partition column support. In this embodiment of the invention, during construction, the worker hoists the steel arch rib above the two steel partition column supports, and then places it on top of the drive wheel 17. The drive wheel 17 on the top of the two steel partition column supports supports the two ends of the steel arch rib respectively. Then, by controlling the lifting hydraulic cylinder 11, the lifting hydraulic cylinder 11 drives the steel arch rib to move upward, thereby adjusting the height of the steel arch rib. The lateral hydraulic cylinder 13 drives the support seat 14 to move, thereby adjusting the lateral side of the steel arch rib. At the same time, by controlling the different extension heights of the two lifting hydraulic cylinders 11, the steel arch rib can be tilted, adjusting the tilt angle of the steel arch rib. After adjustment, the system is controlled... A geared motor 18 drives a drive wheel 17 to rotate, pushing the steel arch rib to align with the already installed steel arch rib, thus completing the splicing of the steel arch rib. Based on this setup, the steel arch rib is placed on the drive wheel 17, and adjusted by the lifting hydraulic cylinder 11 and the lateral hydraulic cylinder 13. This reduces the impact of external wind on the splicing of the steel arch rib, facilitating the splicing process. Some types of steel arch ribs are inclined; therefore, during the splicing and installation process, the steel arch rib needs to be changed from a vertical to an inclined state. In this embodiment, the servo motor 23, equipped with a gearbox, is controlled to drive the rotating shaft 21 and gears to rotate, thereby driving... The rack 22 and adjusting plate 15 slide within the groove, causing the steel arch rib on the drive wheel 17 to tilt. The fixing assembly secures the steel arch rib, thereby adjusting its posture and improving its applicability. After the steel arch rib is placed on the drive wheel 17, the fixing hydraulic cylinder 32 is activated. Initially in a retracted state, the fixing hydraulic cylinder 32 pushes the fixing cover 33 into contact with the surface of the steel arch rib. The fixing hydraulic cylinders 32 on both sides secure the steel arch rib from both sides, reducing movement of the steel arch rib during position adjustment. This also facilitates the fixing of steel arch ribs with a vertically elongated cross-section, further improving its applicability. During the fixing process of the fixing cover 33, the guide wheel first contacts the steel arch rib. The arch ribs come into contact, and under the pressure, the guide wheel, wheel frame 42, and piston rod 41 move towards the first piston cylinder 34. The return spring is compressed, and the first piston cylinder 34 is filled with hydraulic oil. Then, the hydraulic oil in the rodless chamber of the first piston cylinder 34 enters the rod chamber of the first piston cylinder 34 from the first through groove 44 and the second through groove 45. When the drive wheel 17 drives the steel arch ribs to splice, it is necessary to first control the fixing hydraulic cylinder 32 to separate the fixing cover 33 from the steel arch ribs. Then, the return spring continuously pushes out the piston rod 41, and the guide wheel remains in contact with the surface of the steel arch ribs. In the prior art, an anti-rotation mechanism is installed between the hydraulic cylinder and the piston rod 41. In this embodiment of the invention, an anti-rotation mechanism is installed between the first piston cylinder 34 and the piston rod 41.The piston rod 41 and the first piston cylinder 34 are not easily rotated. The guide wheel is kept vertical by a torsion spring by default. During the splicing process of the drive wheel 17 pushing the steel arch rib, the guide wheel drives the wheel frame 42 to deflect due to friction, which in turn drives the sealing rod 43 to deflect, thus preventing the first through groove 44 and the second through groove 45 from communicating, thereby preventing the hydraulic oil from flowing. This fixes the piston rod 41, the wheel frame 42, and the guide wheel. By setting the guide wheel to contact the steel arch rib, the steel arch rib can be guided from both sides during the splicing process, reducing the swaying of the steel arch rib during movement and improving the positioning and splicing accuracy. After the splicing is completed, the fixed hydraulic cylinder 32 retracts, causing the guide wheel to reset and separate from the steel arch rib. Then, the wheel frame 42 rotates and resets under the action of the torsion spring. During the process of lowering the steel arch rib to the drive wheel 17, the elastic plate 53 under the steel arch rib is pressed, causing it to bend and deform to fit against the steel arch rib. Then, the guide rod 52 slides into the second piston cylinder 51. The other elastic plates 53 in contact with the steel arch rib will also deform accordingly. By relying on the above settings, the contact area between the drive wheel 17 and the lower surface of the steel arch rib can be increased, thereby improving the fixing effect of the steel arch rib and reducing the possibility of the steel arch rib slipping off the drive wheel 17. This allows the drive wheel 17 to stably control the splicing of the steel arch rib and reduce the possibility of the steel arch rib sliding under its own weight, which could lead to collisions between the steel arch ribs. During the lowering of the steel arch rib, the guide rod 52 will slide into the second piston cylinder 51, thereby bringing... As the piston plate 61 slides, hydraulic oil in the rodless chamber of the second piston cylinder 51 is injected into the rod chamber through oil hole 63. This, in conjunction with the buffer spring, absorbs the kinetic energy of the falling steel arch rib, providing cushioning and shock absorption. Simultaneously, when the buffer spring drives the guide rod 52 to reset, the hydraulic oil in the rod chamber of the second piston cylinder 51 pushes the sealing ring 62 through oil hole 63, causing the sealing ring 62 to separate from the piston plate 61. Initially, under the action of the sealing spring, the sealing ring 62 is in contact with the surface of the piston plate 61, blocking part of the oil hole 63. Multiple grooves 64 are also provided on the sealing ring 62 to prevent it from blocking all the oil holes 63. During the reset process of the guide rod 52, the hydraulic oil pushes open the sealing ring 62, opening all the oil holes 63. This can improve the reset speed of the piston plate 61 and the guide rod 52. When the guide rod 52 falls, the excess oil hole 63 is closed, reducing the downward movement speed of the guide rod 52 and playing a buffering and damping role. With the above settings, during the rotation of the drive wheel 17, the guide rod 52 located directly above is compressed to the maximum length inside the second piston cylinder 51. As the drive wheel 17 continues to rotate, the guide rod 52 will continuously extend out of the second piston cylinder 51. With the above settings, the extension speed of the guide rod 52 can be accelerated to facilitate stable contact with the steel arch rib. During construction, the steel arch rib bridge is built on the riverbank, where the air humidity is high, causing condensation to easily form on the surface of the metal elastic plate 53. In this embodiment of the invention, before construction, the reduction motor 18 is controlled to drive the drive wheel 17 to rotate one revolution.Afterwards, the surface of the elastic plate 53 can be wiped with the absorbent cotton tube 72 to remove surface dew, thereby increasing the friction with the surface of the elastic plate 53 to facilitate driving and fixation of the heavy steel arch ribs. The waterproof cover 71 covers the surface of the absorbent cotton tube 72, thereby reducing the adhesion of dew and moisture to the surface of the absorbent cotton tube 72, making it easier to keep the absorbent cotton tube 72 dry. On sunny days, the drying personnel can control the reduction motor 18 to drive the drive wheel 17 to rotate to a certain extent, and then drive the connecting shaft 85 and the friction wheel 84 to rotate under the action of the belt. The friction wheel 84 uses friction to make the rubber wheel 83, the fixed shaft 82 and the arc-shaped baffle 81 rotate, thereby opening the arc-shaped baffle 81, which facilitates the drying of the absorbent cotton tube 72, thus keeping the absorbent cotton tube 72 dry. After drying, the servo motor 23 is controlled to drive the drive wheel 17 to rotate in the opposite direction, thereby making the arc-shaped baffle 81 enter the dry state. The waterproof cover 71 is closed to reduce moisture absorption of the absorbent cotton tube 72 inside. An arc-shaped rubber pad 91 improves the fit between the waterproof cover 71 and the elastic plate 53, reducing the inflow of moisture and rainwater through the gap between them, thus preventing the absorbent cotton tube 72 from becoming damp. A sealing strip 92 enhances the sealing effect between the arc-shaped baffles 81. A reflective strip 93 reflects sunlight off the arc-shaped baffles 81, allowing sunlight to penetrate the interior of the waterproof cover 71 and keeping the absorbent cotton tube 72 dry. A first pulley 101 reduces friction as the adjusting plate 15 slides in the groove, facilitating rotation by the servo motor 23. A second pulley 102 reduces friction between the support base 14 and the base 12, facilitating adjustment by the lateral hydraulic cylinder 13.
