Description

Technical Field

[0001] This application relates to the field of arch bridge construction equipment, and in particular to an auxiliary installation device for the pull-down and hanging of the suspenders of a tie-rod arch bridge. Background Technology

[0002] In the construction of a tied arch bridge, the bridge deck frame is laid first, and then the arch ribs are installed on both sides of the bridge deck. During the installation of the arch ribs, wind braces are simultaneously installed between the two arch ribs. Finally, hangers are installed between the arch ribs and the bridge deck.

[0003] During the installation of the arch ribs, the bridge deck was unobstructed, facilitating the use of floating cranes to install the wind braces and arch ribs onto the deck. Later, during the installation of the suspenders, the arch ribs obstructed the view, requiring workers to use a crane to install the suspenders between the arch ribs and the bridge deck. At the time of suspender installation, the bridge deck was still just a frame, preventing the crane from traveling on it. Therefore, workers first needed to install steel plates on the bridge deck to allow the crane to move. Then, workers used the crane to install the suspenders between the arch ribs and the bridge deck. After the suspenders were installed, the steel plates were removed, increasing the difficulty of the suspender installation. Summary of the Invention

[0004] To facilitate the installation of the suspenders, this application provides an auxiliary installation device for the pull-down and hanging of the suspenders of a tie-rod arch bridge.

[0005] This application provides an auxiliary installation device for the pull-down and hanging-up of the suspenders of a tie-rod arch bridge, which adopts the following technical solution:

[0006] A bottom-bearing tied arch bridge gantry lowering and upper hanging auxiliary installation device includes a suspended basket body. Two rotating rods are rotatably mounted on the suspended basket body. A winding reel is fixedly mounted at both ends of each rotating rod. A rotating mechanism is installed between the rotating rods and the suspended basket body. The rotating mechanism drives the rotating rods to rotate. A lifting rope is provided on the winding reel. One end of the lifting rope is connected to the winding reel, and the other end of the lifting rope is equipped with a clamping mechanism for clamping the arch rib. A balancing mechanism is installed on the suspended basket body to keep the suspended basket body balanced.

[0007] By adopting the above technical solution, construction workers, inside the suspended platform body, then clamp the clamping mechanisms at both ends of the first rotating rod to the arch rib, thus suspending the suspended platform on the arch rib. When it is necessary to move the suspended platform body, the clamping mechanisms at both ends of the second rotating rod are clamped onto the arch rib. Then, the rotating mechanism is activated to drive the second rotating rod to rotate, causing the winding reel to wind up the hoisting rope. When the suspended platform body moves below the clamping mechanism corresponding to the second rotating rod, the rotating mechanism stops driving the second rotating rod to rotate. Then, the clamping mechanisms at both ends of the first rotating rod are removed from the arch rib. By alternately clamping the arch rib with the clamping mechanisms on the first and second rotating rods, it is convenient for the suspended platform body to move on the arch rib to the position where the hoisting rod is installed.

[0008] As the suspended platform is moved to the location for installing the booms, workers on the bridge deck erect the booms for installation by those on the suspended platform. After installing one boom, the suspended platform is moved again to another boom installation location. This movement of the suspended platform along the arch ribs assists workers in installing the booms between the arch ribs and the bridge deck, eliminating the need to lay and dismantle steel plates on the bridge deck, thus facilitating boom installation.

[0009] The clamping mechanisms at both ends of the rotating rod are separated from each other. When encountering the wind brace between the two arch ribs, the clamping mechanism can avoid the wind brace, thereby reducing the occurrence of the wind brace hindering the movement of the falling body.

[0010] Optionally, the clamping mechanism includes a sliding rod, an upper clamping plate, a lower clamping plate, and a sliding assembly. One end of the sliding rod is fixedly connected to the end of the lifting rope away from the winding reel, and the other end of the sliding rod is fixedly connected to one side of the upper clamping plate. The lower clamping plate has a through hole for the sliding rod to pass through. The sliding assembly is installed between the sliding rod and the lower clamping plate, and the sliding assembly is used to drive the lower clamping plate to slide along the length direction of the sliding rod.

[0011] By adopting the above technical solution, when it is necessary to clamp the clamping mechanism onto the arch rib, the sliding rod is first hung on the arch rib via the upper clamping plate. Then, the sliding assembly is activated, causing the lower clamping plate to move towards the upper clamping plate, thereby clamping the arch rib between the upper and lower clamping plates. Since the arch rib is arc-shaped, clamping it with the upper and lower clamping plates reduces the likelihood of the suspended platform body automatically sliding on the arch rib.

[0012] Optionally, the sliding assembly includes a support tube, a screw, a slider, a first push block, and a second push block. One end of the support tube is fixedly connected to the body of the sliding rod. The support tube is located on the side of the lower clamping plate away from the upper clamping plate. The screw is threaded through the support tube. The body of the support tube has a sliding opening for the slider to slide. The slider abuts against the end of the screw near the sliding rod. The first push block is fixedly installed on the side of the lower clamping plate away from the upper clamping plate. The second push block is fixedly connected to the slider. The bottom side of the first push block and the top side of the second push block are both inclined.

[0013] By adopting the above technical solution, the rotating screw moves towards the sliding rod, and the screw pushes the slider to move towards the sliding rod. The slider drives the second push block to press against the first push block. Through the inclination of the first and second push blocks, the force is divided, thereby pushing the lower clamping plate to move towards the upper clamping plate, thus facilitating the driving of the upper and lower clamping plates to clamp the arch rib.

[0014] Rotating the screw moves it away from the sliding rod, releasing the slider. The weight of the lower clamping plate causes the first push block to move downwards, pressing against the second push block, thus pushing the second push block away from the sliding rod. After the second push block moves away from the sliding rod, the lower and upper clamping plates release the arch rib, making it easier to remove the clamping mechanism from the arch rib.

[0015] Optionally, a drive block is fixedly installed at the end of the screw away from the sliding rod, and a telescopic rod is provided between the screws at both ends of the same rotating rod. Both ends of the telescopic rod are provided with grooves for the drive block to be inserted into the damping mechanism.

[0016] By adopting the above technical solution, the drive block damping is inserted into the groove, and then the length of the telescopic rod is adjusted, so that the two sliding rods can easily abut against the side wall of the arch rib. Then, the telescopic rod is rotated, and the telescopic rod is engaged with the groove through the drive block, thereby driving the screws located at both ends of the rotating rod to rotate together, which in turn facilitates the adjustment of the clamping mechanisms located at both ends of the rotating rod to loosen or clamp the arch rib together.

[0017] Optionally, the balancing mechanism includes balancing components disposed on opposite sides of the suspended platform body. The balancing components include a lifting sleeve and a first push rod. The lifting sleeve is fixedly installed on the outer side wall of the suspended platform body, and the first push rod is threaded through the lifting sleeve and is vertically arranged.

[0018] By adopting the above technical solution, when the suspended platform body moves to the position where the suspension rods are installed, the suspended platform body is suspended by the suspension ropes on both sides, thereby reducing the possibility of the suspended platform body tilting towards the side where the suspension ropes are located. Then, the first jacking rod is rotated so that it is pressed tightly against the bottom side of the arch rib, thereby reducing the possibility of the suspended platform body tilting towards the side where the first jacking rod is located.

[0019] When the suspended platform needs to move along the arch rib, the first jacking rod is rotated, causing it to move downwards and creating space between it and the arch rib. This space reduces the likelihood of the jacking rod obstructing the movement of the suspended platform along the arch rib.

[0020] Optionally, a second top rod is hinged to the top of the first top rod. The first top rod is provided with a limiting sleeve. The limiting sleeve is slidably sleeved on the first top rod and the second top rod. A lifting assembly is installed between the limiting sleeve and the first top rod. The lifting assembly is used to drive the limiting sleeve to rise and fall.

[0021] By adopting the above technical solution, when the suspended platform moves along the arch rib, the lifting assembly slides the limiting sleeve downwards, separating the limiting sleeve from the second top rod. Then, as the second top rod presses against the bottom side of the arch rib, it rotates. After the suspended platform completes its movement, the height of the first top rod is adjusted, and then the lifting assembly pushes the limiting sleeve upwards. The limiting sleeve pushes the second top rod to rotate vertically, and then the limiting sleeve fits onto the second top rod. The second sleeve, fitted onto both the first and second top rods, restricts the rotation of the second top rod. The second top rod then presses tightly against the bottom side of the arch rib, thus helping to maintain the balance of the suspended platform.

[0022] Optionally, the lifting assembly includes a first support ring, a second support ring, and a spring. The first support ring is fixedly sleeved on the first top rod, the second support ring is fixedly sleeved on the second top rod, the sliding sleeve is located between the first support ring and the second support ring, the spring is fixedly installed between the first support ring and the sliding sleeve, the spring is used to drive the sliding sleeve to abut against the second support ring, and the spring is loosely sleeved on the first top rod.

[0023] By adopting the above technical solution, the limiting sleeve is pulled downwards and moves closer to the first support ring. The limiting sleeve compresses the spring and separates from the second push rod, thus facilitating the rotation of the second push rod and reducing the possibility of the second push rod getting stuck with the arch rib, which would affect the movement of the suspended platform. When it is necessary for the second push rod to be pressed tightly against the bottom side of the arch rib to keep the suspended platform balanced, the first push rod is adjusted for raising or lowering. Then, the spring drives the limiting sleeve to move upwards and press against the second support ring, thus facilitating the second push rod to remain vertical and pressed tightly against the bottom side of the arch rib, thereby maintaining the balance of the suspended platform.

[0024] Optionally, the rotating rod and the winding reel are both located on the bottom side of the suspended basket body. The end of the lifting rope away from the winding reel passes through the bottom side of the suspended basket body and is connected to the clamping mechanism. The rotating mechanism includes a motor, a first pulley, a second pulley, and a transmission belt. The motor body is fixedly installed on the bottom side of the suspended basket body. The first pulley is fixedly sleeved on the rotating shaft of the motor. The second pulley is fixedly sleeved on the rotating rod. The transmission belt is sleeved on the first pulley and the second pulley. The motor can rotate in the forward or reverse direction.

[0025] By adopting the above technical solution, the motor drives the rotating rod to rotate via the first pulley, the second pulley, and the transmission belt. The forward or reverse rotation of the motor causes the rotating rod to rotate accordingly, thus facilitating the winding reel to wind or unwind the suspension rope.

[0026] Optionally, a shield is fixedly installed on the bottom side of the suspended basket body, and the rotating rod, rotating mechanism and winding reel are all located inside the shield. A caster wheel is fixedly installed on the bottom side of the shield.

[0027] By adopting the above technical solution, the shield protects the rotating rod, rotating mechanism, and reel, thereby reducing the likelihood of damage to these components. The casters facilitate the transport of the suspended platform to the arch bridge.

[0028] Optionally, the shield is equipped with a plurality of counterweights, the top side of which is connected to the bottom side of the suspended basket body, and the bottom side of which is connected to the inner bottom wall of the shield.

[0029] By adopting the above technical solution, the counterweight is used to increase the weight of the suspended platform, thereby helping to maintain its balance. At the same time, the counterweight supports the shield, thereby reducing the possibility of the shield collapsing.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The clamping mechanisms at both ends of the first rotating rod clamp the arch rib. Then, the clamping mechanisms at both ends of the second rotating rod extend in the direction that the suspended platform body needs to move and clamp the arch rib. After that, the rotating mechanism is started to drive the second rotating rod to rotate. The second rotating rod drives the winding reel to rotate and wind up the suspension rope, thereby moving the suspended platform body to below the clamping mechanisms at both ends of the second rotating rod. Then, the clamping mechanisms at both ends of the first rotating rod release the arch rib. The clamping mechanisms on the two rotating rods alternately clamp the arch rib, thereby moving the suspended platform body along the arch rib. The suspended platform body moves on the arch rib to the position where the suspension rod needs to be installed. After the construction personnel install the suspension rod, they continue to move to the next position where the suspension rod needs to be installed. This eliminates the need to lay steel plates on the bridge deck, thus facilitating the installation of the suspension rod.

[0032] 2. By inserting the drive block of the same rotating rod into the groove, and then rotating the telescopic rod, the screw moves towards the sliding rod, so that the first push block and the second push block press against each other and drive the lower clamping plate closer to the upper clamping plate, thereby facilitating the clamping of the arch rib by the upper and lower clamping plates.

[0033] 3. By increasing the weight of the suspended platform body through counterweights, the likelihood of the platform body swaying due to movement of the workers is reduced. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0044] This application discloses an auxiliary installation device for the pull-down and hanging of the suspenders of a tie-rod arch bridge.

[0045] Reference Figure 1 , Figure 2 A bottom-bearing tied arch bridge suspender lowering and upper hanging auxiliary installation device includes a suspended basket body 1. A shield 2 is fixedly installed on the bottom side of the suspended basket body 1, and casters 3 are installed at the four corners of the outer bottom wall of the shield 2. The casters 3 facilitate the movement of the suspended basket body 1 on the ground, thereby facilitating the transportation of the suspended basket body 1 to the arch bridge.

[0046] Reference Figure 2 , Figure 3 The shield 2 has multiple counterweights 4 inside, which are fixedly installed on the inner bottom wall of the shield 2, with the top side of the counterweights 4 abutting against the outer bottom wall of the suspended platform body 1. The counterweights 4 increase the weight of the suspended platform body 1, thus facilitating stability when suspended from the arch rib 20 and reducing swaying. Simultaneously, the counterweights 4 support the shield 2, thereby reducing the likelihood of denting or deformation when the shield 2 is subjected to pressure.

[0047] Reference Figure 3 The shield 2 has two rotating rods 5 inside. The rods 5 are rotatably connected to the outer bottom wall of the suspended basket body 1. Each rotating rod 5 is equipped with a rotating mechanism 6. The rotating mechanism 6 includes a motor 61, a first pulley 62, a second pulley 63, and a conveyor belt 64.

[0048] Reference Figure 3 The motor 61 can rotate in either direction, and its body is fixedly installed on the outer bottom wall of the suspended platform body 1. The first pulley 62 is fixedly sleeved on the rotating shaft of the motor 61, and the second pulley 63 is fixedly sleeved on the rotating rod 5. The conveyor belt 64 is sleeved on the first pulley 62 and the second pulley 63.

[0049] When the motor 61 is started, it drives the rotating rod 5 to rotate via the first pulley 62, the second pulley 63, and the transmission belt 64. The rotation of the motor 61 in either the forward or reverse direction facilitates the rotation of the rotating rod 5 in either direction.

[0050] Reference Figure 2 , Figure 3 Both ends of the rotating rod 5 are fixedly installed with a winding reel 7, and the winding reel 7 is equipped with a lifting rope 8. The rotating rod 5 drives the winding reel 7 to rotate, thereby facilitating the winding reel 7 to wind or unwind the lifting rope 8.

[0051] Reference Figure 2 The end of the lifting rope 8 away from the reel 7 passes through the bottom side of the basket body 1 and is connected to a clamping mechanism 9. The lifting rope 8 clamps the arch rib 20 through the clamping mechanism 9. The clamping mechanisms 9 at both ends of the rotating rod 5 clamp the arch rib 20 from both sides, thus facilitating the suspension of the basket body 1 on the arch rib 20. At the same time, when the lifting rope 8 passes through the bottom side of the basket body 1, the basket body 1 limits the movement of the lifting rope 8, thereby reducing the possibility of the lifting rope 8 moving during the winding and unwinding of the reel 7.

[0052] Reference Figure 4 , Figure 5 When the clamping mechanisms 9 at both ends of the first rotating rod 5 clamp the arch rib 20, the clamping mechanisms 9 at both ends of the second rotating rod 5 extend obliquely from the basket and clamp the arch rib 20. Then, the rotating mechanism 6 drives the second rotating rod 5 to rotate, allowing the winding reel 7 located on the second rotating rod 5 to wind up the hoisting rope 8, thereby moving the basket body 1 below the clamping mechanisms 9 at both ends of the second rotating rod 5. Then, the clamping mechanisms 9 at both ends of the first rotating rod 5 are removed from the arch rib 20, and then obliquely extend the clamping mechanisms 9 at both ends of the first rotating rod 5 out of the basket body 1 and clamp the arch rib 20. By alternately clamping the arch rib 20 with the clamping mechanisms 9 located on the two rotating rods 5, and then by rotating mechanism 6 driving winding reel 7 to wind and unwind, the basket body 1 moves on the arch rib 20 to the position where the suspender rod 22 needs to be installed. The basket body 1 provides a platform for construction workers to stand and install the suspender rod 22, thus eliminating the need to lay steel plates on the bridge deck 19, thereby facilitating the installation of the suspender rod 22.

[0053] Reference Figure 4 , Figure 5 The arch rib 20 and the wind brace 21 are heavy, so when installing the arch rib 20, a floating crane is needed to install the wind brace 21 together with the arch rib 20. The clamping mechanism 9 located at both ends of the rotating rod 5 separates the arch rib 20, so that when the basket body 1 moves past the wind brace 21, the clamping mechanism 9 passes around the wind brace 21 and clamps the arch rib 20.

[0054] Reference Figure 6 , Figure 7 The clamping mechanism 9 includes a sliding rod 91, an upper clamping plate 92, a lower clamping plate 93, and a sliding assembly 94. One end of the sliding rod 91 is fixedly connected to the end of the lifting rope 8 away from the winding reel 7, and the other end of the sliding rod 91 is fixedly connected to one side of the upper clamping plate 92. The lower clamping plate 93 has a through hole 10 for the sliding rod 91 to slide through.

[0055] Reference Figure 6 , Figure 7The sliding assembly 94 includes a support tube 941, a screw 942, a slider 943, a first push block 944, and a second push block 945. One end of the support tube 941 is fixedly connected to the body of the sliding rod 91, and the support tube 941 is located on the side of the lower clamping plate 93 away from the upper clamping plate 92. The screw 942 is threaded through the support tube 941, and the body of the support tube 941 has a sliding opening 11 for the slider 943 to slide. The slider 943 abuts against the end of the screw 942 near the sliding rod 91. The first push block 944 is fixedly installed on the side of the lower clamping plate 93 away from the upper clamping plate 92, and the bottom side of the second push block 945 is fixedly connected to the slider 943. The bottom side of the first push block 944 and the top side of the second push block 945 are both inclined and abut against each other.

[0056] Rotate screw 942 to push slider 943 towards sliding rod 91. Slider 943 drives second push block 945 towards sliding rod 91. By tilting the bottom side of first push block 944 and the top side of second push block 945, first push block 944 pushes lower clamping plate 93 towards upper clamping plate 92, thus facilitating the clamping of arch rib 20 by upper clamping plate 92 and lower clamping plate 93.

[0057] Rotate screw 942 to move it away from slider 943. Lower clamping plate 93 drives first push block 944 to press second push block 945 downward, thereby moving second push block 945 away from sliding rod 91. Then upper clamping plate 92 and lower clamping plate 93 release arch rib 20, making it easier to remove clamping mechanism 9 from arch rib 20.

[0058] Reference Figure 6 , Figure 7 A drive block 12 is fixedly installed at the end of the screw 942 away from the sliding rod 91, and a telescopic rod 13 is provided between the screws 942 at both ends of the same rotating rod 5. Both ends of the telescopic rod 13 are provided with grooves 14 for the drive block 12 to be inserted into for damping.

[0059] Insert the drive blocks 12 at both ends of the same rotating rod 5 into the grooves 14, and then adjust the length of the telescopic rod 13 so that the sliding rods 91 located at both ends of the same rotating rod 5 abut against the side wall of the arch rib 20. Then rotate the telescopic rod 13, which will drive the two drive blocks 12 to rotate together, thereby facilitating the two clamping mechanisms 9 to clamp the arch rib 20 together, or to release the arch rib 20.

[0060] After the clamping mechanism 9 clamps the arch rib 20, the telescopic rod 13 is shortened, and then the drive block 12 is pulled out from the groove 14, so that the telescopic rod 13 can be easily removed from between the two clamping mechanisms 9.

[0061] Reference Figure 3 , Figure 8The suspended platform body 1 is equipped with a balancing mechanism, which includes two balancing components 15. The suspension ropes 8 are located on opposite sides of the suspended platform body 1, and the two balancing components 15 are located on the other opposite sides of the suspended platform body 1.

[0062] Reference Figure 3 , Figure 8 The balancing assembly 15 includes a lifting sleeve 151 and a first push rod 152. The outer wall of the lifting sleeve 151 is fixedly installed on the outer wall of the suspended platform body 1. The first push rod 152 is threaded through the lifting sleeve 151 and is vertically arranged. A second push rod 16 is hinged to the bottom end of the first push rod 152. The first push rod 152 is provided with a limit sleeve 18 and a lifting assembly 17.

[0063] Reference Figure 3 , Figure 8 The lifting assembly 17 includes a first support ring 171, a second support ring 172, and a spring 173. The first support ring 171 is fixedly sleeved on the first top rod 152, and the second support ring 172 is fixedly sleeved on the second support ring 172. A limiting sleeve 18 is located between the first support ring 171 and the second support ring 172. The spring 173 is fixedly installed between the limiting sleeve 18 and the first support ring 171, and the spring 173 is used to drive the limiting sleeve 18 to press tightly against the second support ring 172.

[0064] Reference Figure 5 , Figure 8 When the suspended platform body 1 is suspended on the arch rib 20, the first jacking rod 152 is rotated so that the second jacking rod 16 is pressed tightly against the bottom side of the arch rib 20. When the construction workers move the suspended platform body 1, the second jacking rod 16 and the suspension rope 8 together restrict the suspended platform body 1 from tilting in all directions, thereby improving the balance of the suspended platform body 1.

[0065] As the suspended platform body 1 moves along the arch rib 20, the limiting sleeve 18 is pulled downwards. The second push rod 16 then rotates under the pressure of the bottom side of the arch rib 20, facilitating the movement of the suspended platform body 1. Afterwards, the limiting sleeve 18 is released, and the second push rod 16 bends under the pressure of the bottom side of the arch rib 20, preventing the spring 173 from driving the second push rod 16 to rotate vertically via the limiting sleeve 18. After the suspended platform body 1 stops moving, the first push rod 152 is rotated to provide sufficient space between the first push rod 152 and the bottom side of the arch rib 20 for the second push rod 16 to be vertical. The spring 173 then pushes the limiting sleeve 18 into the second push rod 16. The second push rod 16 then rests against the bottom side of the arch rib 20, balancing the suspended platform body 1.

[0066] The implementation principle of the auxiliary installation device for the suspender rod of the tie-rod arch bridge according to the embodiment of this application is as follows: the suspender body 1 is suspended from the arch rib 20 by the clamping mechanism 9, and then the construction personnel install the suspender rod 22 on the arch rib 20 inside the suspender body 1. Therefore, it is not necessary to lay steel plates on the bridge deck 19, and it is not necessary to remove the steel plates after the suspender rod 22 is installed, which facilitates the installation of the suspender rod 22.

[0067] The arch rib 20 is alternately clamped by the clamping mechanism 9 on the two rotating rods 5, which facilitates the movement of the suspended basket body 1 on the arch rib 20. By moving the suspended basket body 1 on the arch rib 20, the occurrence of the suspended basket body 1 repeatedly descending back to the bridge deck 19 is reduced, thereby facilitating the installation of the suspender rod 22.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
