[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the mobile walking system moves the guardrail on the bridge. When the guardrail moves to the side wall of the bridge, the mounting frame and the supporting frame are constructed so that the supporting frame is located at the outer edge of the side wall of the bridge. The operator can walk on the mounting frame and the supporting frame to reach the position of the side wall of the bridge where the guardrail needs to be installed. The guardrail to be installed is then hoisted by the established hoisting system and hoisted onto the placement table. The position of the guardrail is then adjusted by the personnel on the supporting frame to install the guardrail.

[0013] When the lifting device is installed at a suitable position, the lifting device can be used to lift the guardrail and adjust the height of the guardrail so that the lifting device can move up and down, and the lifting device can be used to lift the guardrail and adjust the height of the guardrail so that the lifting device can be used to lift the guardrail and adjust the height of the guardrail.

[0014] In the present invention, when the guardrail is hoisted by the hoisting system and moves toward the support frame where the operator is located, the guardrail is above the placement table, and the operator holds the guardrail to move it down along the side plate frame on the placement table, and the bottom of the guardrail will contact the carrying plates on the two groups of clamping seats, and the downward pressure of the guardrail causes the carrying plates to gradually drive the load-bearing rods to gradually move downward in the clamping seats, and when the load-bearing rods move downward, they will drive the two groups of hinged clamping frames to move downward, and in the process of the clamping frames moving downward, the arc grooves on the clamping frames contact the limit blocks, and under the restriction of the limit blocks, the two groups of clamping frames are deflected toward the outer wall of the guardrail, and the deflected clamping frames can clamp and limit the bottom of the guardrail, and at this time, the bottom of the guardrail is fixed by the two groups of clamping mechanisms to fix the guardrail in the shaking process, so that the guardrail can move stably during the installation process, which is convenient for the installation of the guardrail.

[0015] In the present invention, when the guardrail is not in contact with the surface of the mounting plate, the tension spring arranged between the wedge-shaped clamping rod and the clamping seat causes one end of the wedge-shaped clamping rod to move toward the side wall of the placement table. At this time, the fixing rod on the wedge-shaped clamping rod is clamped with the clamping interface on the placement table. At this time, under the restriction of the wedge-shaped clamping rod, the clamping mechanism and the placement table can be in a connected state, so that the guardrail can be stably placed when placed on the mounting plate. After the guardrail contacts the mounting plate, the mounting plate is compressed to drive the load-bearing rod to move downward, and the load-bearing rod moves downward to move the wedge-shaped clamping groove arranged at its bottom, and then under the drive of the wedge-shaped clamping groove, the wedge-shaped clamping rod can move toward the end away from the placement seat. At this time, the wedge-shaped clamping rod is directly separated from the placement table, so that the clamping seat placed on the placement table can slide. At this time, the clamping seat and the placement table are no longer in a limited state, so that the subsequent movement of the clamping seat to adjust the position of the guardrail can be convenient.

[0016] In the present invention, when the bottom of the guardrail contacts the surface of the carrying plate and the wedge-shaped clamping rod extends outward, the annular clamping joint provided at the end of the wedge-shaped clamping rod abuts against the sleeve on the bracket. At this time, after the wedge-shaped clamping rod and the bracket are locked and connected, the operator can drive the mobile frame to slide on the placement table through the handle provided on the outer wall of the mobile frame. Because a connecting spring is provided between the mobile frame and the transmission frame, and one of the clamping wheels on the transmission frame abuts against the limiting groove on the mobile frame, the mobile frame can synchronously drive the transmission frame to move during the movement. The movement of the transmission frame will drive the clamping seat to slide on the placement table, so that the guardrail on the clamping seat can be stably pushed toward the outer wall of the bridge, so that the bridge gradually approaches the outer wall of the bridge. When the guardrail reaches the installation position close to the bridge, another set of clamping wheels on the transmission frame will engage with the interference grooves on the clamping plate. At this time, the operator can no longer drive the transmission frame to move under the restriction of the clamping plate when pushing the moving frame, so that the transmission frame can be locked to the clamping plate, restricting the guardrail to the specified installation position, thereby facilitating the operator to install the guardrail on the outer wall of the bridge.

[0017] In the present invention, when the guardrail is restricted to the specified position of the placement table and the two ends of the guardrail cannot contact the outer wall of the bridge, the operator can drive the moving frame to continue to push it. At this time, the moving frame is pushed. Because the transmission frame and the limiting plate are limited, the moving frame will move and will gradually separate from the transmission frame. The transmission gear on the moving frame will rotate under the restriction of the fixed gear. The rotation of the transmission gear will drive the moving rack to push toward the direction of the bridge. After the moving rack is pushed in the direction of the bridge, the measuring teeth set on the top of the moving rack will contact the outer wall of the bridge, and then the distance between the bridge and the guardrail can be determined by the measuring teeth. Subsequently, the entire equipment is driven to move in the direction of the bridge by the mobile walking system, thereby ensuring the safety of the guardrail during installation. Even if the guardrail cannot fit tightly against the bridge after reaching the specified position, its position can be accurately adjusted while ensuring safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a guardrail installation trolley for construction, comprising a mobile walking system 1, a hoisting system 11 is set up on the top of the mobile walking system 1, a supporting device 2 is set up on the top of the mobile walking system 1 and located next to the hoisting system 11, and the supporting device 2 comprises a mounting frame 21 connected to the top of the mobile walking system 1, and a support frame 22 is also hingedly set on the mounting frame 21; A support plate 23 is fixedly connected to the inner wall of the support frame 22, and oppositely arranged support members 3 are arranged on the top of the support plate 23, and a placement platform 38 is fixedly connected to the top of the two groups of support members 3, and a side baffle 39 is fixedly arranged on the placement platform 38, and a clamping mechanism 4 is respectively arranged on both sides of the side baffle 39 on the top of the placement platform 38; The top of the placing platform 38 is also provided with a relatively sliding moving mechanism 5, and two sets of moving mechanisms 5 are respectively located beside the clamping mechanism 4; Driven by the mobile walking system 1, it moves on the bridge. When it moves to the side wall of the bridge, the mounting frame 21 and the support frame 22 are constructed so that the support frame 22 is located at the outer edge of the side wall of the bridge. The operator can walk on the mounting frame 21 and the support frame 22 to reach the position of the bridge side wall where the guardrail needs to be installed, and then the guardrail to be installed is hoisted by the established hoisting system 11, and the guardrail is hoisted onto the placement table 38. Then, the position of the guardrail is adjusted by the personnel located on the support frame 22, and the guardrail is installed.

[0022] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the two groups of support members 3 opposite to each other at the top of the support plate 23 include a base 31 fixedly arranged on the top of the support plate 23, a support rod 32 is slidably arranged in the base 31, a load-bearing spring 33 is arranged between the support rod 32 and the inner bottom of the base 31, a limiting groove 34 is provided on the outer wall of the base 31, and a limiting frame 35 is extended outward from the outer wall of the support rod 32 to the limit groove 34, and the limiting frame 35 is slidably matched with the limiting groove 34, and an elastic telescopic clamping block 36 is arranged on the limiting frame 35, and the upper end face of the clamping block 36 is an inclined surface and the lower end face is a plane, and a limiting plate is also fixedly arranged on the base 31, and a plurality of clamping grooves 37 are arranged on the limiting plate at equal intervals in the longitudinal direction, and the clamping block 36 abuts against the clamping groove 37, and the placing table 38 is fixedly arranged on the top of the two groups of support rods 32; The initial position of the clamping block 36 on the limiting frame 35 is at the bottom of the clamping groove 37 on the limiting plate. After the guardrail is clamped by the clamping device, the clamping device limits the guardrail on the placement table 38, and the guardrail is driven upward by the hoisting system 11. When the appropriate installation position is adjusted, the hoisting system 11 drives the guardrail upward and simultaneously drives the placement table 38 upward due to the clamping work of the clamping device. When the placement table 38 moves upward, the support rod 32 set at the bottom of the placement table 38 will move upward on the base 31, and the clamping block 36 set on the limiting frame 35 will The clamping groove 37 on the limit plate interferes with the clamping block 36. Since the upper end surface of the clamping block 36 is an inclined structure, when the clamping block 36 contacts the clamping groove 37 during the upward movement, it will drive the clamping block 36 to shrink in the limit frame 35, which will not affect the upward movement of the clamping block 36. After the lifting system 11 adjusts the height installation position of the guardrail, the bottom of the clamping block 36 is a flat structure that can effectively abut against the clamping groove 37, thereby maintaining the position of the placement platform 38 stable, and avoiding the placement platform 38 from shaking when the lateral position of the guardrail is subsequently adjusted, which affects the installation and use of the guardrail.

[0023] In this embodiment, Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the two groups of clamping mechanisms 4 both include a clamping seat 41 placed on the surface of the placing table 38, a cavity 42 is provided inside the clamping seat 41, a bearing rod 43 is provided in the cavity 42, a carrying plate 44 is provided on the top of the bearing rod 43, a pressure spring 45 is provided between the bearing rod 43 and the cavity 42, and relatively arranged limit blocks 46 are provided on the inner wall of the clamping seat 41, and clamping frames 47 are hingedly provided on the outer wall of the bearing rod 43 in the direction of the two groups of limit blocks 46, and arc grooves 48 are provided on the surfaces of the two groups of clamping frames 47, and the limit blocks 46 on the clamping seat 41 are located in the arc grooves 48 in the clamping frames 47, and the carrying plate 44 is located between the two groups of clamping frames 47; When the guardrail is hoisted by the hoisting system 11 and moves toward the support frame 22 where the operator is located, the guardrail is above the placement table 38, and the operator holds the guardrail to move it down along the side plate frame on the placement table 38, and the bottom of the guardrail will contact the carrying plate 44 on the two groups of clamping seats 41. The downward pressure of the guardrail causes the carrying plate 44 to gradually drive the load-bearing rod 43 to gradually move downward in the clamping seat 41. When the load-bearing rod 43 moves downward, it will drive the two groups of hinged clamping frames 47 to move downward. During the downward movement of the clamping frames 47, the arc grooves 48 on the clamping frames 47 contact the limit blocks 46. Under the restriction of the limit blocks 46, the two groups of clamping frames 47 are deflected toward the outer wall of the guardrail. The deflected clamping frames 47 can clamp and limit the bottom of the guardrail. At this time, the bottom of the guardrail is fixed by the two groups of clamping mechanisms 4 to fix the guardrail in the shaking process, so that the guardrail can move stably during the installation process, which is convenient for the installation of the guardrail.

[0024] In this embodiment, Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the clamping mechanism 4 further includes a wedge-shaped clamping rod 49 slidably disposed on the clamping seat 41, a tension spring 401 is disposed between the wedge-shaped clamping rod 49 and the clamping seat 41, a telescopic fixing rod 402 is disposed at one end of the wedge-shaped clamping rod 49, and a clamping interface that is clamped with the fixing rod 402 is disposed on the side wall of the placement platform 38; The lower end of the load-bearing rod 43 is also provided with a wedge-shaped slot 403, and the wedge-shaped clamping rod 49 slides on the clamping seat 41 and extends to the other end of the clamping seat 41 through the wedge-shaped slot 403, and the wedge-shaped clamping rod 49 contacts the wedge-shaped slot 403 on the load-bearing rod 43, so that it can extend toward the outside of the clamping seat 41 under the drive of the wedge-shaped slot 403; when the guardrail is not in contact with the surface of the carrying plate 44, the tension spring 401 arranged between the wedge-shaped clamping rod 49 and the clamping seat 41 causes one end of the wedge-shaped clamping rod 49 to move toward the side wall of the placement table 38, and at this time, the fixing rod 402 on the wedge-shaped clamping rod 49 is clamped with the clamping interface on the placement table 38, and at this time, under the restriction of the wedge-shaped clamping rod 49, The clamping mechanism 4 is connected to the placement table 38, so that the guardrail can be stably placed on the mounting plate 44. After the guardrail contacts the mounting plate 44, the mounting plate 44 is pressed to drive the load-bearing rod 43 downward, and the load-bearing rod 43 moves downward to move the wedge-shaped slot 403 arranged at the bottom thereof, and then driven by the wedge-shaped slot 403, the wedge-shaped clamping rod 49 can move toward the end away from the placement seat. At this time, the wedge-shaped clamping rod 49 is directly separated from the placement table 38, so that the clamping seat 41 placed on the placement table 38 can slide. At this time, the clamping seat 41 and the placement table 38 are no longer in a limited state, so that the subsequent movement of the clamping seat 41 can facilitate the adjustment of the position of the guardrail.

[0025] In this embodiment, Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the two groups of moving mechanisms 5 both include a moving frame 51 slidably arranged on the placement table 38, a moving groove 52 is opened on the outer wall of the placement table 38, a handle 53 is extended from the outer wall of the moving frame 51 to the outside of the moving groove 52, and the moving frame 51 and the moving groove 52 are slidably matched, and a transmission frame 54 is also slidably arranged on the moving frame 51, a connecting rod 55 is fixedly arranged on the transmission frame 54, a connecting spring 56 is sleeved on the connecting rod 55, and the two ends of the connecting spring 56 are respectively connected to the transmission frame 54 and the moving frame 51, and a card shaft 57 is rotatably arranged on the outer wall of the transmission frame 54, and a torsion spring is arranged on the card shaft 57. A card plate 58 is also fixedly provided, and two groups of card wheels 59 are arranged opposite to each other on the card plate 58. A limiting groove 501 is arranged on the inner wall of the movable frame 51, which is in contact with one of the card wheels 59 on the card plate 58. A limiting plate 502 is fixedly connected to the inner wall of the placing table 38 at one end away from the side baffle plate 39, and a positioning groove 503 is arranged on the limiting plate 502 to be in contact with the other card wheel 59 on the card plate 58. A bracket 504 is extended from the outer wall of the transmission frame 54 toward the clamping seat 41, and an annular card joint 404 is arranged at one end of the wedge-shaped card rod 49, and a sleeve 505 is arranged on the bracket 504 to be sleeved with the annular card joint 404. The movable frame 51 is also provided with a receiving groove, in which a transmission gear 506 is rotatably arranged, a fixed rack 507 is fixedly arranged on the inner wall of the transmission frame 54, and a movable rack 508 is also slidably arranged on the movable frame 51, and the movable rack 508 and the fixed rack 507 are both meshed with the transmission gear 506, and a telescopic measuring tooth 509 is arranged at the end of the movable rack 508; When the bottom of the guardrail contacts the surface of the mounting plate 44, the wedge-shaped clamping rod 49 extends outward, and the annular clamping joint 404 provided at the end of the wedge-shaped clamping rod 49 abuts against the sleeve 505 on the bracket 504. At this time, after the wedge-shaped clamping rod 49 and the bracket 504 are locked and connected, the operator can drive the mobile frame 51 to slide on the placement table 38 through the handle 53 provided on the outer wall of the mobile frame 51. Because a connecting spring 56 is provided between the mobile frame 51 and the transmission frame 54, and one of the clamping wheels 59 on the transmission frame 54 abuts against the limiting groove 501 on the mobile frame 51, the mobile frame 51 can be synchronously driven during the movement. The transmission frame 54 is moved, and the movement of the transmission frame 54 will drive the clamping seat 41 to slide on the placement table 38, so that the guardrail on the clamping seat 41 can be stably pushed toward the outer wall of the bridge, so that the bridge gradually approaches the outer wall of the bridge. When the guardrail reaches the installation position close to the bridge, another set of card wheels 59 on the transmission frame 54 will be engaged with the abutment grooves on the card plate 58. At this time, the operator pushes the moving frame 51 and can no longer drive the transmission frame 54 to move under the restriction of the card plate 58, so that the transmission frame 54 can be locked to the card plate 58, and the guardrail is restricted to the specified installation position, so that it is convenient for the operator to install the guardrail on the outer wall of the bridge; When the guardrail is restricted to the specified position of the placement table 38 and the two ends of the guardrail cannot contact the outer wall of the bridge, the operator can drive the moving frame 51 to continue to push. At this time, the moving frame 51 is pushed. Because the transmission frame 54 and the limiting plate 502 are limited, the moving frame 51 will move and will gradually separate from the transmission frame 54. The transmission gear 506 on the moving frame 51 will rotate under the restriction of the fixed gear. The rotation of the transmission gear 506 will drive the moving rack 508 to push in the direction of the bridge. After the moving rack 508 is pushed in the direction of the bridge, the measuring tooth 509 set on the top of the moving rack 508 will contact the outer wall of the bridge, and then the distance between the bridge and the guardrail can be determined by the measuring tooth 509. Subsequently, the mobile walking system 1 is used to drive the entire equipment to move in the direction of the bridge, thereby ensuring the safety of the guardrail during installation. Even if the guardrail cannot fit tightly against the bridge after reaching the specified position, its position can be accurately adjusted while ensuring safety.

[0026] In this embodiment, Figure 1 and Figure 2As shown, the support device 2 also includes two groups of driving electric cylinders 24 fixedly arranged on the top of the mobile walking system 1, the bottoms of the two groups of driving electric rods are hingedly matched with the top of the mobile walking system 1, and a fixing plate 25 is fixedly arranged on the mounting frame 21, and the fixing plate 25 is hingedly matched with the telescopic ends of the two groups of driving electric cylinders 24. The mounting frame 21 is also hingedly provided with a push electric cylinder 26 arranged oppositely, and the telescopic ends of the two groups of push electric cylinders 26 are respectively hingedly matched with the two sides of the support frame 22, and the support frame 22 and the mounting frame 21 are connected. A damping rod 27 is also hingedly arranged in the middle; the driving electric cylinder 24 can drive the mounting frame 21 to be lifted and lowered on the top of the mobile walking system 1, so that the mounting frame 21 and the support frame 22 will not cause obstacles when moving in normal road sections, and the pushing electric cylinder 26 on the mounting frame 21 can drive the support frame 22 to be lifted, which can prevent the support frame 22 from causing congestion on the road. The damping rod 27 can make the support frame 22 move slowly downward when it reaches the outer wall of the bridge to ensure the safety performance of the guardrail installation.

[0027] The use method and advantages of the present invention: The use method of the guardrail installation trolley for construction, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown: the mobile walking system 1 is driven to move on the bridge. When it moves to the side wall of the bridge, the mounting frame 21 and the supporting frame 22 are constructed so that the supporting frame 22 is located at the outer edge of the side wall of the bridge. The operator can walk on the mounting frame 21 and the supporting frame 22 to reach the position of the side wall of the bridge where the guardrail needs to be installed, and then the guardrail to be installed is hoisted by the established hoisting system 11, and the guardrail is hoisted onto the placement table 38. Then, the position of the guardrail is adjusted by the personnel located on the supporting frame 22, and then the guardrail is installed; The initial position of the clamping block 36 on the limiting frame 35 is at the bottom of the clamping groove 37 on the limiting plate. After the guardrail is clamped by the clamping device, the clamping device limits the guardrail on the placement table 38, and the guardrail is driven upward by the hoisting system 11. When the appropriate installation position is adjusted, the hoisting system 11 drives the guardrail upward and simultaneously drives the placement table 38 upward due to the clamping work of the clamping device. When the placement table 38 moves upward, the support rod 32 set at the bottom of the placement table 38 will move upward on the base 31, and the clamping block 36 set on the limiting frame 35 will The clamping groove 37 on the limit plate abuts against the clamping block 36. Since the upper end surface of the clamping block 36 is in an inclined structure, when the clamping block 36 contacts the clamping groove 37 during the upward movement, the clamping block 36 will be driven to shrink in the limit frame 35, which will not affect the upward movement of the clamping block 36. After the hoisting system 11 adjusts the height installation position of the guardrail, the bottom of the clamping block 36 is a flat structure that can effectively abut against the clamping groove 37, thereby maintaining the position of the placement platform 38 stable, avoiding the subsequent shaking of the placement platform 38 when the lateral position of the guardrail is adjusted, which affects the installation and use of the guardrail. When the guardrail is hoisted by the hoisting system 11 and moves toward the support frame 22 where the operator is located, the guardrail is above the placement table 38, and the operator holds the guardrail to make it move down along the side plate frame on the placement table 38, and the bottom of the guardrail will contact the carrying plates 44 on the two groups of clamping seats 41. The downward pressure of the guardrail causes the carrying plates 44 to gradually drive the load-bearing rods 43 to gradually move down in the clamping seats 41. When the load-bearing rods 43 move down, it will drive the two groups of hinged clamping frames 47 to move downward. During the downward movement of the clamping frames 47, the arc grooves 48 on the clamping frames 47 contact the limit blocks 46. Under the restriction of the limit blocks 46, the two groups of clamping frames 47 are deflected toward the outer wall of the guardrail. The deflected clamping frames 47 can clamp and limit the bottom of the guardrail. At this time, the bottom of the guardrail is fixed by the two groups of clamping mechanisms 4 to fix the guardrail in the shaking process, so that the guardrail can move stably during the installation process, which is convenient for the installation of the guardrail. When the guardrail is not in contact with the surface of the mounting plate 44, the tension spring 401 arranged between the wedge-shaped clamping rod 49 and the clamping seat 41 causes one end of the wedge-shaped clamping rod 49 to move toward the side wall of the placement table 38. At this time, the fixing rod 402 on the wedge-shaped clamping rod 49 is engaged with the clamping interface on the placement table 38. At this time, under the restriction of the wedge-shaped clamping rod 49, the clamping mechanism 4 and the placement table 38 can be in a connected state, so that the guardrail can be placed stably on the mounting plate 44. After the guardrail contacts the mounting plate 44, After the carrying plate 44 is pressed and drives the bearing rod 43 to move downward, the bearing rod 43 moves downward to move the wedge-shaped slot 403 arranged at the bottom thereof, and then driven by the wedge-shaped slot 403, the wedge-shaped clamping rod 49 can move toward the end away from the placement seat, at this time, the wedge-shaped clamping rod 49 is directly separated from the placement table 38, so that the clamping seat 41 placed on the placement table 38 can slide, and at this time, the clamping seat 41 and the placement table 38 are no longer in a limited position state, so that the subsequent movement of the clamping seat 41 to adjust the position of the guardrail can be facilitated; When the bottom of the guardrail contacts the surface of the mounting plate 44, the wedge-shaped clamping rod 49 extends outward, and the annular clamping joint 404 provided at the end of the wedge-shaped clamping rod 49 abuts against the sleeve 505 on the bracket 504. At this time, after the wedge-shaped clamping rod 49 and the bracket 504 are locked and connected, the operator can drive the mobile frame 51 to slide on the placement table 38 through the handle 53 provided on the outer wall of the mobile frame 51. Because a connecting spring 56 is provided between the mobile frame 51 and the transmission frame 54, and one of the clamping wheels 59 on the transmission frame 54 abuts against the limiting groove 501 on the mobile frame 51, the mobile frame 51 can be synchronously driven during the movement. The transmission frame 54 is moved, and the movement of the transmission frame 54 will drive the clamping seat 41 to slide on the placement table 38, so that the guardrail on the clamping seat 41 can be stably pushed toward the outer wall of the bridge, so that the bridge gradually approaches the outer wall of the bridge. When the guardrail reaches the installation position close to the bridge, another set of card wheels 59 on the transmission frame 54 will be engaged with the abutment grooves on the card plate 58. At this time, the operator pushes the moving frame 51 and can no longer drive the transmission frame 54 to move under the restriction of the card plate 58, so that the transmission frame 54 can be locked to the card plate 58, and the guardrail is restricted to the specified installation position, so that it is convenient for the operator to install the guardrail on the outer wall of the bridge; When the guardrail is restricted to the specified position of the placement table 38 and the two ends of the guardrail cannot contact the outer wall of the bridge, the operator can drive the moving frame 51 to continue to push. At this time, the moving frame 51 is pushed. Because the transmission frame 54 and the limiting plate 502 are limited, the moving frame 51 will move and will gradually separate from the transmission frame 54. The transmission gear 506 on the moving frame 51 will rotate under the restriction of the fixed gear. The rotation of the transmission gear 506 will drive the moving rack 508 to push in the direction of the bridge. After the moving rack 508 is pushed in the direction of the bridge, the measuring tooth 509 set on the top of the moving rack 508 will contact the outer wall of the bridge, and then the distance between the bridge and the guardrail can be determined by the measuring tooth 509. Subsequently, the mobile walking system 1 is used to drive the entire equipment to move in the direction of the bridge, thereby ensuring the safety of the guardrail during installation. Even if the guardrail cannot fit tightly against the bridge after reaching the specified position, its position can be accurately adjusted while ensuring safety.
