[0022] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0023] Please refer to Figures 1-3, the hanger rod replacement device 1 for the hanger rod 21 of the arch bridge of the present utility model includes a support assembly 11, a moving assembly 12 and a hoisting assembly 13. The support assembly 11 includes a support cable 111 and at least two pairs of support beams 112 arranged in pairs. The support beams 112 arranged in pairs are symmetrically arranged on both sides of the arch rib 2, and at least two groups of the support beams 112 are fixedly arranged on the arch rib 2 in an array. The support cable 111 is arranged on the support beams 112 and is fixedly connected to both ends of the arch rib 2 at both ends. The moving assembly 12 includes a driving wheel 121 and a connecting frame 122. The driving wheel 121 is installed on the connecting frame 122 to drive the connecting frame 122 to move along the arch rib 2. Connecting rings 123 slidably connected to the support cable 111 are arranged on both sides of the connecting frame 122. The hoisting assembly 13 includes a conversion beam 131, a first hoisting rope 132, a second hoisting rope 133 and a hoisting driving member 134. The hoisting driving member 134 is installed on the connecting frame 122. The first hoisting ropes 132 are symmetrically arranged on both sides of the hoisting driving member 134. One ends of the first hoisting ropes 132 on both sides are wound around the hoisting driving member 134, and the other ends are connected to the conversion beam 131. The second hoisting ropes 133 are symmetrically arranged on both sides of the hoisting plate. One ends of the second hoisting ropes 133 on both sides are fixedly connected to the conversion beam 131, and the other ends are detachably connected to the steel beam at the bottom of the bridge deck.

[0024] Before performing the operation of replacing the hanger rod 21, first fixedly arrange the support beams 112 in an array on the arch rib 2, and fixedly connect both ends of the support cable 111 to both ends of the arch rib 2. At the same time, arrange the support cable 111 on the support beams 112 on both sides of the arch rib 2, so that the support cable 111 and the arch rib 2 provide support for the moving assembly 12 at the same time. That is, the arch rib 2 provides support for the driving wheel 121, and the support cable 111 provides support for the connecting frame 122. Thus, when the driving wheel 121 moves along the arch rib 2, the support cable 111 always provides support for the connecting frame 122 to keep the connecting frame 122 balanced. Among them, both ends of the arch rib 2 are Figure 1 both sides in the X-axis direction in Figure 1 both sides in the Y-axis direction in.

[0025] Install the hoisting driving member 134 on the connecting frame 122, and wind one end of the first hoisting rope 132 around both sides of the hoisting driving member 134, and the other end is fixedly connected to the conversion beam 131, so that the conversion beam 131 can be driven to lift under the drive of the hoisting driving member 134. Fix one end of the second hoisting rope 133 on both sides of the conversion beam 131, and the other end is connected to the steel beam. After the hoisting driving member 134 winds up the first hoisting rope 132 and makes the first hoisting rope 132 and the second hoisting rope 133 taut, the tension of the suspender 21 on the bridge deck can be transferred to the first hoisting rope 132 and the second hoisting rope 133, and then it is convenient for the operators to disassemble and replace the suspender 21.

[0026] When performing the replacement operation of the suspender 21, control the driving wheel 121 to move along the arch rib 2, so that the driving wheel 121 drives the connecting frame 122 to move to the position corresponding to the suspender 21 and then stop moving. At this time, control the hoisting driving member 134 to wind up the first hoisting rope 132 to tighten the first hoisting rope 132 and the second hoisting rope 133, so that the tension of the suspender 21 on the bridge deck is transferred to the first hoisting rope 132 and the second hoisting rope 133, which is convenient for the operators to replace the suspender 21 and improves the efficiency of replacing the suspender 21.

[0027] During the process of replacing the suspender 21, the connecting ring 123 is slidably connected to the support cable 111 to provide balanced support for the connecting frame 122 under the action of the connecting ring 123. When the balance of the connecting frame 122 is offset, one side of the support cable 111 can support the connecting ring 123, and at the same time, the connecting ring 123 on the other side pulls the support cable 111, so that the forces on both sides of the support cable 111 are balanced, and finally the connecting frame 122 is kept balanced.

[0028] By setting the second hoisting rope 133 to be detachably connected to the steel beam, it is convenient to disassemble the second hoisting rope 133 from the steel beam after replacing the current suspender 21. At the same time, make the hoisting driving member 134 wind up the first hoisting rope 132, and the driving wheel 121 moves along the arch rib 2 to drive the connecting frame 122 to move to the next suspender 21, and at the same time, the conversion beam 131 is transported to the next suspender 21. Subsequently, let the hoisting driving member 134 unwind the first hoisting rope 132, so that it is convenient for the operators to fix the second hoisting rope 133 on the steel beam, which is convenient for the hoisting driving member 134 to wind up the first hoisting rope 132 and tighten the second hoisting rope 133 through the conversion beam 131, and then transfer the tension of the suspender 21 on the bridge deck to the first hoisting rope 132 and the second hoisting rope 133. At this time, it is convenient for the operators to perform the replacement operation of the suspender 21.

[0029] In the above embodiments, hooks are provided on the steel beam, and spring buckles are provided on the second lifting rope 133. When connecting the second lifting rope 133 to the steel beam, by pulling the spring buckle and engaging the spring buckle with the hook, the connection between the second lifting rope 133 and the steel beam is realized. Furthermore, the hoisting driving member 134 can wind up the first hoisting rope 132, causing the conversion beam 131 to rise along with the first hoisting rope and pulling the second hoisting rope 133 taut, so as to transfer the tension of the suspender 21 on the bridge deck to the hoisting assembly. At this time, the suspender 21 at the first hoisting rope 132 can be replaced. After completing the replacement operation of the current suspender 21, the spring buckle can be removed from the hook, so that when the driving wheel 121 drives the second hoisting rope 133 to move to the position of the next suspender 21, the spring buckle can be engaged with the steel beam hook corresponding to the suspender 21 again.

[0030] In an embodiment of the present utility model, the driving wheel 121 is a motor wheel and is equipped with an electronic brake, so as to drive the connecting frame 122 to move along the arch rib 2 under the rotation of the motor wheel, and keep the connecting frame 122 balanced during the movement under the supporting action of the supporting cable 111 on the connecting frame 122. When the motor wheel moves to the position corresponding to the suspender 21, the electronic brake transmits a braking signal and controls the motor wheel to brake, so as to keep the position of the motor wheel fixed and prevent the moving assembly 12 from displacing during the replacement operation of the suspender 21.

[0031] In the above embodiments, the hoisting driving member 134 is any one of an electric hoist and a crane, so as to wind up the first hoisting rope 132. There are two first hoisting ropes 132, and the two first hoisting ropes 132 are respectively wound around both sides of the hoisting driving member 134, and the other ends of the two first hoisting ropes 132 are fixed on both sides of the conversion beam 131, so that when the hoisting driving member 134 works, it can drive the two first hoisting ropes 132 to wind up and unwind simultaneously, and keep the force on the conversion beam 131 balanced during the winding and unwinding process.

[0032] In the above embodiments, the detachable connection mode between the second hoisting rope 133 and the steel beam adopts hook connection, which is convenient for the operator to quickly disassemble the second hoisting rope 133 and improves the operation efficiency.

[0033] In the above embodiments, the conversion beam 131 includes a first conversion beam, a second conversion beam and a plugging rod. The plugging rod is fixedly connected to the side surface of the first conversion beam, and a jack for inserting the plugging rod is provided on the side surface of the second conversion beam, so that after the plugging rod is inserted into the second conversion beam, the first conversion beam and the second conversion beam are spliced into a complete plate surface. Through holes are provided on the mutually contacting surfaces of the first conversion beam and the second conversion beam, so as to enclose the suspender 21 in the through holes after the plugging rod is inserted into the second conversion beam, which is convenient for subsequent replacement of the suspender 21.

[0034] In the above embodiments, the first conversion beam and the second conversion beam are both made of steel beams, and the insertion rod is a square steel insertion rod to enhance the structural strength after the splicing of the first conversion beam and the second conversion beam, and to prevent the structural strength of the conversion beam 131 from being insufficient, resulting in the inability of the first hoisting rope 132 and the second hoisting rope 133 to withstand the tension on the bridge deck after being straightened, and further causing the conversion beam 131 to be damaged and a safety accident to occur.

[0035] In an embodiment of the present utility model, a jack 135 is provided on the conversion beam 131. The output end of the jack 135 passes through the conversion beam 131 and can abut against the bridge deck to tension the second hoisting rope 133, thereby realizing the adjustment of the tension of the second hoisting rope 133, so as to reduce the distance between the steel beam and the arch bridge deck, and transfer the tension of the suspender 21 on the bridge deck to the second hoisting rope 133, which is convenient for the operator to replace the suspender 21. Among them, by adjusting the tension of the jack 135 in batches, the tension of the second hoisting rope 133 on the steel beam can be adjusted, which is convenient for the operator to accurately adjust the tension of the second hoisting rope 133, so as to facilitate the replacement of the suspender 21.

[0036] In an embodiment of the present utility model, the connecting frame 122 is in an n shape, the driving wheel 121 is installed at the middle position of the connecting frame 122, protruding horizontal ear plates 1221 are provided on both sides of the connecting frame 122, the connecting ring 123 is installed on the horizontal ear plates 1221, and reinforcing ribs are provided between the horizontal ear plates 1221 and the connecting frame 122.

[0037] By designing the connecting frame 122 in an n shape, it is convenient for the driving wheel 121 to be installed at the middle position of the connecting frame 122, so that when the driving wheel 121 moves on the arch rib 2, it drives the connecting frame 122 to move synchronously. The connecting ring 123 is installed on the horizontal ear plates 1221 on both sides of the connecting frame 122 to provide support for the connecting frame 122 in cooperation with the support cable 111, and to enhance the stability when the driving wheel 121 moves. By providing reinforcing ribs between the horizontal ear plates 1221 and the connecting frame 122, the structural strength and load-bearing capacity of the connecting frame 122 are improved, ensuring the stability and safety during the replacement of the suspender 21.

[0038] In an embodiment of the present utility model, the connecting ring 123 includes a connecting end and a limiting end. The connecting end is a screw rod, the limiting end is a circular ring, the connecting end passes through the horizontal ear plate 1221 and is connected by a nut, and the limiting end is sleeved on the support cable 111.

[0039] The connecting end is passed through the horizontal ear plate 1221 and then connected by a nut to fix the connecting ring 123 on the horizontal ear plate 1221. Thus, before fixing the support cable 111 at both ends of the arch rib 2, the support cable 111 can be passed through the limiting end first, so that the limiting end provides support for the connecting frame 122, and when the driving wheel 121 moves, the connecting ring 123 can slide on the support cable 111. At the same time, it can also prevent the connecting ring 123 and the support cable 111 from disengaging, improving the safety and reliability during the replacement process of the suspender 21.

[0040] The connecting end and the horizontal ear plate 1221 are set to be connected by a nut, so that when the wear of the limiting end is relatively large, the connecting ring 123 can be disassembled from the horizontal ear plate 1221 for replacement to reduce potential safety hazards.

[0041] In an embodiment of the present invention, at least two rollers 1222 are provided at the bottom of the connecting frame 122, and an arch surface is provided on the surface of the support beam 112. When the driving wheel 121 moves on the arch rib 2, it can drive the rollers 1222 to fit with the arch surface, so that when the driving wheel 121 moves to the support beam 112, the rollers 1222 roll on the arch surface, reducing the friction force and support force of the support cable 111 on the connecting ring 123, ensuring the balance and stable movement of the entire connecting frame 122. At the same time, it reduces the possible wear of the connecting ring 123 and the support cable 111 due to friction, prolonging the service life of the connecting ring 123 and the support cable 111. At the same time, when the rolling wheel 1222 moves to the second support end 1122, the second support end 1122 can prevent the moving component 12 from sliding down from the support component 11, improving the stability of the moving component 12 on the support component 11.

[0042] In an embodiment of the present invention, the support beam 112 is Z-shaped and includes a first support end 1121, a second support end 1122, and a third support end 1123. The first support end 1121 and the third support end 1123 are in a vertical state. The surface of the first support end 1121 is fixedly connected to the side surface of the arch rib 2. A limiting groove adapted to the support cable 111 is provided at the top of the third support end 1123. The second support end 1122 is in a horizontal state and is fixedly connected to the first support end 1121 and the third support end 1123 on both sides respectively. A reinforcing rib is provided between the first support end 1121 and the second support end 1122.

[0043] By setting the support beam 112 in a Z - shape, the first support end 1121 is fixedly connected to the side surface of the arch rib 2. A limit groove is formed in the third support end 1123 to provide support and limit for the support cable 111 under the action of the limit groove. Then, the support cable 111 provides support for the connecting frame 122 and keeps the connecting frame 122 balanced. By connecting the second support end 1122 between the first support end 1121 and the third support end 1123 and arranging a reinforcing rib between the first support end 1121 and the second support end 1122, the structural stability of the support beam 112 is enhanced, and the bearing capacity and anti - deformation ability of the support beam 112 are improved.

[0044] In the embodiment of the present utility model, the arch surface is arranged on the surface of the second support end 1122. An arc segment 1124 is arranged at the top of the third support end 1123. The limit groove is formed on the arc segment 1124. The radian of the arc segment 1124 is adapted to the radian of the arch surface, and the arc segment 1124 is detachably connected to the third support end 1123.

[0045] By setting the second support end 1122 as an arch surface and arranging an arc segment 1124 with a radian adapted to the arch surface on the third support segment, the support cable 111 can be supported and limited in the limit groove on the arc segment 1124. When the driving wheel 121 moves onto the support beam 112, the roller 1222 contacts the arch surface and raises the height of the connecting frame 122. At the same time, the radian of the arc segment 1124 is coordinated to reduce the friction between the connecting ring 123 and the limit groove, facilitating the connecting ring 123 to cross the arc segment 1124, so that the driving wheel 121 drives the connecting frame 122 to move to the position of the next suspension rod 21. At the same time, when the rolling wheel 1222 moves onto the second support end 1122, the second support end 1122 can prevent the moving component 12 from slipping on the support component 11, improving the stability of the moving component 12 on the support component 11.

[0046] By setting the arc segment 1124 to be detachably connected to the third support end 1123, it is convenient to replace the arc segment 1124 when the wear of the limit groove is large, improving the maintenance portability and repair efficiency of the support beam 112. The detachable connection method between the arc segment 1124 and the third support end 1123 adopts plug - in connection, that is, a slider is arranged on the arc segment 1124 and a chute is arranged on the third support end 1123, so that the slider is slidably inserted into the chute, thereby realizing the detachable connection between the arc segment 1124 and the third support end 1123.

[0047] In an embodiment of the present utility model, the number of the support cables 111 is set to four. Two rows of the connecting rings 123 are connected side by side on a single horizontal ear plate 1221, and the two rows of the connecting rings 123 are respectively sleeved on two of the support cables 111.

[0048] By connecting four support cables 111 to four rows of connecting rings 123, the support stability of the support cables 111 for the connecting frame 122 is increased, ensuring that the connecting frame 122 remains balanced during movement.

[0049] In an embodiment of the present utility model, the width of the driving wheel 121 is adapted to the thickness of the arch rib 2, and a groove adapted to the arch rib 2 is formed on the circumferential surface of the driving wheel 121.

[0050] By precisely adapting the width of the driving wheel 121 to the thickness of the arch rib 2, it is ensured that the driving wheel 121 can fit on the surface of the arch rib 2. A groove adapted to the shape of the arch rib 2 is formed on the driving wheel 121 to increase the contact area between the driving wheel 121 and the arch rib 2, improve the grip of the driving wheel 121, and at the same time reduce the risk of the driving wheel 121 slipping, improving the use safety of the hanger rod 21 replacement device 1.

[0051] To solve the problems in the prior art, the present utility model further provides a hanger rod 21 replacement system for the arch rib 2 of the hanger rod 21, which is applied to the above-mentioned hanger rod 21 replacement device 1. The hanger rod 21 replacement system includes a movement control module and a hoisting control module. The movement control module is electrically connected to the driving wheel 121 to control the rotation of the driving wheel 121, and the hoisting control module is electrically connected to the hoisting driving member 134 to control the hoisting of the hoisting driving member 134.

[0052] By respectively controlling the rotation of the driving wheel 121 and the hoisting operation of the hoisting driving member 134 through the movement control module and the hoisting control module, it is convenient for the operator to control the driving wheel 121 and the hoisting driving member 134 on the bridge deck, and further convenient for the operators to carry out division of labor operations to realize the replacement operation of the hanger rod 21.

[0053] Before performing the replacement operation of the hanger rod 21, first fix the support beams 112 in an array on the arch rib 2, fix the two ends of the support cables 111 to the two ends of the arch rib 2, and at the same time make the support cables 111 span on the support beams 112 on both sides of the arch rib 2, so that the support cables 111 and the arch rib 2 simultaneously provide support for the moving assembly 12. That is, the arch rib 2 provides support for the driving wheel 121, and the support cables 111 provide support for the connecting frame 122, so that the support cables 111 always provide support for the connecting frame 122 when the driving wheel 121 moves along the arch rib 2, so that the connecting frame 122 remains balanced. Among them, the two ends of the arch rib 2 are Figure 1On both sides in the X-axis direction, both sides of the arch rib 2 are sufficient. Figure 1 On both sides in the Y-axis direction.

[0054] Install the hoisting driving member 134 on the connecting frame 122, and wind one end of the first hoisting rope 132 around both sides of the hoisting driving member 134, and fix the other end to the conversion beam 131. Thus, the conversion beam 131 can be driven to lift and lower under the drive of the hoisting driving member 134. Fix one end of the second hoisting rope 133 on both sides of the conversion beam 131, and connect the other end to the steel beam. Thus, after the hoisting driving member 134 winds up the first hoisting rope 132 and makes the first hoisting rope 132 and the second hoisting rope 133 taut, the tension of the suspender 21 on the bridge deck can be transferred to the first hoisting rope 132 and the second hoisting rope 133, and then it is convenient for the operators to disassemble and replace the suspender 21.

[0055] When performing the replacement operation of the suspender 21, control the driving wheel 121 to move along the arch rib 2, so that the driving wheel 121 drives the connecting frame 122 to move to the position corresponding to the suspender 21 and then stop moving. At this time, control the hoisting driving member 134 to wind up the first hoisting rope 132 to tighten the first hoisting rope 132 and the second hoisting rope 133, so that the tension of the suspender 21 on the bridge deck is transferred to the first hoisting rope 132 and the second hoisting rope 133, which is convenient for the operators to replace the suspender 21 and improves the efficiency of replacing the suspender 21.

[0056] During the replacement operation of the suspender 21, the connecting ring 123 is slidably connected to the support cable 111 to provide a balanced support for the connecting frame 122 under the action of the connecting ring 123. When the balance of the connecting frame 122 is offset, one side of the support cable 111 can support the connecting ring 123, and at the same time, the other side of the connecting ring 123 pulls the support cable 111, so that the forces on both sides of the support cable 111 are balanced, and finally the connecting frame 122 is kept balanced.

[0057] By setting the second hoisting rope 133 to be detachably connected to the steel beam, it is convenient to disassemble the second hoisting rope 133 from the steel beam after the replacement of the current suspender 21 is completed. At the same time, make the hoisting driving member 134 wind up the first hoisting rope 132, and the driving wheel 121 moves along the arch rib 2 to drive the connecting frame 122 to move to the next suspender 21, and at the same time, the conversion beam 131 is transported to the next suspender 21. Subsequently, release the first hoisting rope 132 by the hoisting driving member 134, so that it is convenient for the operators to fix the second hoisting rope 133 on the steel beam, and it is convenient for the hoisting driving member 134 to wind up the first hoisting rope 132 and tighten the second hoisting rope 133 through the conversion beam 131, and then transfer the tension of the suspender 21 on the bridge deck to the first hoisting rope 132 and the second hoisting rope 133. At this time, it is convenient for the operators to perform the replacement operation of the suspender 21.

[0058] In an embodiment of the present utility model, the driving wheel 121 is a motor wheel and is equipped with an electronic brake. Under the rotation of the motor wheel, the connecting frame 122 is driven to move along the arch rib 2, and under the supporting action of the supporting cable 111 on the connecting frame 122, the connecting frame 122 is kept balanced during the movement. When the motor wheel moves to the position corresponding to the suspender 21, the electronic brake transmits a braking signal and controls the motor wheel to brake, so that the position of the motor wheel is fixed, avoiding the displacement of the moving assembly 12 during the replacement operation of the suspender 21.

[0059] In the above embodiment, the hoisting driving member 134 is any one of an electric hoist and a crane to wind up the first hoisting rope 132. There are two first hoisting ropes 132, and the two first hoisting ropes 132 are respectively wound around both sides of the hoisting driving member 134, and the other ends of the two first hoisting ropes 132 are fixed to both sides of the conversion beam 131. When the hoisting driving member 134 works, the two first hoisting ropes 132 are simultaneously wound up and unwound, and the conversion beam 131 is kept balanced in the process of winding up and unwinding.

[0060] In the above embodiment, the detachable connection mode between the second hoisting rope 133 and the steel beam is hook connection, which is convenient for the operator to quickly disassemble the second hoisting rope 133 and improve the operation efficiency.

[0061] In the above embodiment, the conversion beam 131 includes a first conversion beam, a second conversion beam and a plugging rod. The first plugging plate is fixedly connected to the side surface of the first conversion beam, and a jack for inserting the plugging rod is provided on the side surface of the second conversion beam, so that after the plugging rod is inserted into the second conversion beam, the first conversion beam and the second conversion beam are spliced into a complete plate surface. Through holes are provided on the mutually attached surfaces of the first conversion beam and the second conversion beam to enclose the suspender 21 in the through holes after the plugging rod is inserted into the second conversion beam, which is convenient for subsequent replacement of the suspender 21.

[0062] In the above embodiment, both the first conversion beam and the second conversion beam are made of steel plates, and the plugging rod is a square steel plugging rod to enhance the structural strength after the first conversion beam and the second conversion beam are spliced, avoiding that the structural strength of the conversion beam 131 is insufficient, resulting in the first hoisting rope 132 and the second hoisting rope 133 being unable to bear the tension on the bridge deck after being straightened, and further causing the conversion beam 131 to be damaged and resulting in a safety accident.

[0063] Please refer to Figure 4 , in order to solve the problems in the prior art, the present utility model also provides a method for replacing the suspender 21 of an arch bridge with a suspender 21, which is applied to the above-mentioned suspender 21 replacement device 1. The method for replacing the suspender 21 includes the following steps

[0064] S1: Control the hoisting drive 134 to move to a position corresponding to the position of the suspension rod 21.

[0065] S2: Fix and connect the second hoisting rope 133 to the steel beam at the bottom of the bridge deck.

[0066] S3: Control the hoisting drive 134 to wind up the first hoisting rope 132 and drive the conversion beam 131 to tighten the second hoisting rope 133.

[0067] S4: Dismantle the suspension rod 21 and install a new suspension rod 21 between the arch rib 2 and the steel beam.

[0068] S5: Dismantle the second hoisting rope 133, and control the hoisting drive 134 to move to a position corresponding to the position of the next suspension rod 21.

[0069] S6: Repeat steps S2 - S5 until all the suspension rods 21 are replaced.

[0070] Before carrying out the operation of replacing the suspension rod 21, first fix the support beams 112 in an array on the arch rib 2, fix both ends of the support cable 111 to both ends of the arch rib 2, and at the same time make the support cable 111 span on the support beams 112 on both sides of the arch rib 2, so that the support cable 111 and the arch rib 2 provide support for the moving assembly 12 at the same time. That is, the arch rib 2 provides support for the driving wheel 121, and the support cable 111 provides support for the connecting frame 122, so that the support cable 111 always provides support for the connecting frame 122 when the driving wheel 121 moves along the arch rib 2, so as to keep the connecting frame 122 balanced. Among them, both ends of the arch rib 2 are Figure 1 both sides in the X - axis direction in Figure 1 both sides in the Y - axis direction in.

[0071] Install the hoisting drive 134 on the connecting frame 122, and wind one end of the first hoisting rope 132 around both sides of the hoisting drive 134, and fix the other end to the conversion beam 131, so that the conversion beam 131 can be driven to lift and lower under the drive of the hoisting drive 134. Fix one end of the second hoisting rope 133 on both sides of the conversion beam 131, and connect the other end to the steel beam. Thus, after the hoisting drive 134 winds up the first hoisting rope 132 and makes the first hoisting rope 132 and the second hoisting rope 133 tightened, the tension of the suspension rod 21 on the bridge deck can be transferred to the first hoisting rope 132 and the second hoisting rope 133, and then it is convenient for the operators to carry out the dismantling and replacement operations of the suspension rod 21.

[0072] When performing the replacement operation of the suspender 21, by controlling the driving wheel 121 to move along the arch rib 2, the driving wheel 121 drives the connecting frame 122 to move to the position corresponding to the suspender 21 and then stops moving. At this time, by controlling the hoisting driving member 134 to wind up the first hoisting rope 132, the first hoisting rope 132 and the second hoisting rope 133 are tightened, so that the tension of the suspender 21 on the bridge deck is transferred to the first hoisting rope 132 and the second hoisting rope 133, facilitating the operators to replace the suspender 21 and improving the efficiency of replacing the suspender 21.

[0073] During the process of performing the replacement operation of the suspender 21, the connecting ring 123 is slidably connected with the support cable 111, so as to provide balanced support for the connecting frame 122 under the action of the connecting ring 123. When the balance of the connecting frame 122 is offset, one side of the support cable 111 can support the connecting ring 123, and at the same time, the connecting ring 123 on the other side pulls the support cable 111, so that the forces on both sides of the support cable 111 are kept balanced, and finally the connecting frame 122 is kept balanced.

[0074] By making the second hoisting rope 133 detachably connected with the steel beam, it is convenient to detach the second hoisting rope 133 from the steel beam after the replacement of the current suspender 21 is completed. At the same time, the hoisting driving member 134 winds up the first hoisting rope 132, and the driving wheel 121 moves along the arch rib 2 to drive the connecting frame 122 to move to the next suspender 21, and at the same time, the transfer beam 131 is transported to the next suspender 21. Subsequently, by unwinding the first hoisting rope 132 through the hoisting driving member 134, it is convenient for the operators to fix the second hoisting rope 133 on the steel beam, facilitating the hoisting driving member 134 to wind up the first hoisting rope 132 and tighten the second hoisting rope 133 through the transfer beam 131, and then transferring the tension of the suspender 21 on the bridge deck to the first hoisting rope 132 and the second hoisting rope 133. At this time, it is convenient for the operators to perform the replacement operation of the suspender 21.

[0075] In the embodiment of the present utility model, the driving wheel 121 is an electric wheel and is equipped with an electronic brake, so as to drive the connecting frame 122 to move along the arch rib 2 under the rotation of the electric wheel, and keep the connecting frame 122 balanced during the movement under the support of the support cable 111 on the connecting frame 122. When the electric wheel moves to the position corresponding to the suspender 21, the electronic brake transmits a brake signal and controls the electric wheel to brake, so as to keep the position of the electric wheel fixed and avoid the displacement of the moving assembly 12 during the replacement operation of the suspender 21.

[0076] In the above embodiment, the hoisting driving member 134 is any one of an electric hoist and a crane, which is used to wind the first hoisting rope 132. There are two first hoisting ropes 132, and the two first hoisting ropes 132 are respectively wound around both sides of the hoisting driving member 134, and the other ends of the two first hoisting ropes 132 are fixed to both sides of the conversion beam 131, so that when the hoisting driving member 134 works, the two first hoisting ropes 132 are simultaneously wound and unwound, and the force on the conversion beam 131 is kept balanced during the winding and unwinding process.

[0077] In the above embodiment, the detachable connection mode between the second hoisting rope 133 and the steel beam adopts hook connection, which is convenient for the operator to quickly disassemble the second hoisting rope 133 and improve the operation efficiency.

[0078] In the above embodiment, the conversion beam 131 includes a first conversion beam, a second conversion beam and a plugging rod. The first plugging plate is fixedly connected to the side surface of the first conversion beam, and a jacking hole for the plugging rod to insert is formed on the side surface of the second conversion beam, so that after the plugging rod is inserted into the second conversion beam, the first conversion beam and the second conversion beam are spliced into a complete plate surface. Through holes are formed on the mutually attached surfaces of the first conversion beam and the second conversion beam, so that after the plugging rod is inserted into the second conversion beam, the suspender 21 is enclosed in the through holes, which is convenient for subsequent replacement of the suspender 21.

[0079] In the above embodiment, both the first conversion beam and the second conversion beam are made of steel plates, and the plugging rod is a square steel plugging rod, so as to strengthen the structural strength after the first conversion beam and the second conversion beam are spliced, and avoid the situation that the structural strength of the conversion beam 131 is insufficient, resulting in the inability of the first hoisting rope 132 and the second hoisting rope 133 to bear the tension on the bridge deck after being straightened, and further causing the conversion beam 131 to be damaged and a safety accident to occur.

[0080] In the embodiment of the present utility model, a jack 135 is arranged on the conversion beam 131. The output end of the jack 135 passes through the conversion beam 131 and can abut against the bridge deck to tension the second hoisting rope 133, so as to realize the adjustment of the tension of the second hoisting rope 133, reduce the distance between the steel beam and the arch bridge deck, and transfer the tension of the suspender 21 on the bridge deck to the second hoisting rope 133, which is convenient for the operator to replace the suspender 21. Among them, by adjusting the tension of the jack 135 in batches, the tension of the second hoisting rope 133 on the steel beam can be adjusted, which is convenient for the operator to accurately adjust the tension of the second hoisting rope 133, so as to facilitate the replacement of the suspender 21.
