[0022] Specifically, the supporting and fixing device 2 includes an outer sleeve 21, a fixing component 22, a screw 23, an inner cylinder 24, an outer frame 25 and a threaded hole 26. The outer sleeves 21 are installed on both sides adjacent to each other between the two fixing frames 1, the inner sides of the two outer sleeves 21 are provided with inner cylinders 24, the top of the outer sleeves 21 is provided with screws 23 through threads, and the top of the inner cylinder 24 is provided with multiple threaded holes 26, the outer frame 25 is provided on the outside of the two outer sleeves 21 and above the steel rope 4, and the fixing components 22 are installed on the top and bottom of the outer frame 25 and on one side of the steel rope 4.

[0023] By adopting the above technical solution, the staff can adjust the moving range of the steel rope 4 to a certain extent through the cooperation of the outer sleeve 21 and the inner column 24 and other structures when necessary, so as to better meet the working needs in different situations.

[0024] Specifically, the fixing assembly 22 includes a rubber extrusion block 221, a first knob 222 and a first screw 223. The first screw 223 is threadedly installed on the top and bottom of the outer frame 25 and on one side of the steel rope 4. The rubber extrusion block 221 is installed on the side of the first screw 223 close to the outer sleeve 21 and on the inner side of the outer frame 25 through a bearing, and the first knob 222 is installed on the side of the first screw 223 away from the rubber extrusion block 221.

[0025] By adopting the above technical solution, the staff can prevent the steel rope 4 from moving when necessary through the cooperation of the first screw rod 223 and the rubber extrusion block 221 and other structures, thereby better meeting the work needs in different situations.

[0026] Specifically, the inner width of the outer frame 25 is equal to the outer width of the rubber extrusion block 221 .

[0027] By adopting the above technical solution, the tooling can ensure that the inner side of the outer frame 25 and the outer side of the rubber extrusion block 221 can be in close contact with each other, thereby preventing the rubber extrusion block 221 from deviating during the movement.

[0028] When this embodiment is used, when the work of the bridge-building machine requires the use of tooling, the staff screws the two screws 23 in the supporting fixing device 2 to disengage it from the threaded hole 26 on the inner cylinder 24, and then the staff pulls the two outer sleeves 21 to move, thereby adjusting the overall length of the two outer sleeves 21 and the inner cylinder 24, and then adjusting the movable range of the steel rope 4, and then the staff reversely rotates the two screws 23 to connect them with the corresponding threaded holes 26, and then the staff clamps the two fixing frames 1 on the protective wall, and then rotates the two rotating plates 8 respectively, thereby driving the two second screws 7 to rotate respectively, the second screw 7 is threadedly connected to the fixing frame 1, the second screw 7 is bearing-connected to the clamping plate 6, and the outer top surface of the clamping plate 6 is tightly attached to the inner top surface of the fixing frame 1, so the two second screws 7 respectively drive the two clamping plates 6 to move, and then cooperate with the two fixing frames 1 to move the protective wall The two fixing frames 1 are clamped to fix the positions of the two fixing frames 1. The staff members wear the safety belts 3 and then use them to prevent the staff members from accidentally falling when working at high altitudes. When it is necessary to prevent the steel rope 4, the outer frame 25 and other structures from moving outside the two outer sleeves 21 and the inner column 24, the staff members before work or other staff members during work respectively turn the first knobs 222 in the two fixing assemblies 22, thereby driving the two first screw rods 223 to rotate. The first screw rod 223 is threadedly connected to the outer frame 25, and the first screw rod 223 is bearing-connected to the rubber extrusion block 221. Therefore, the two first screw rods 223 drive the two rubber extrusion blocks 221 to move, thereby clamping the outer sleeve 21 or the inner column 24, thereby fixing the position of the outer frame 25, thereby preventing the steel rope 4, the outer frame 25 and other structures from moving outside the two outer sleeves 21 and the inner column 24.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the storage and adjustment device 5 includes a storage box 51, a second knob 52, a screw rod 53 and a clamping frame 54. The storage box 51 is installed below the outer frame 25 and at a position outside the top of the steel rope 4. The screw rod 53 is installed on both sides of the storage box 51 through bearings. The second knob 52 is installed on the side of the screw rod 53 away from the storage box 51, and the clamping frame 54 is installed on the outside of the screw rod 53 through threads.

[0031] By adopting the above technical solution, the staff can store the excess part of the steel rope 4 when necessary through the cooperation of the storage box 51 and the clamping frame 54, so as to adjust the overall length of the steel rope 4 to a certain extent, so as to better meet the work needs in different situations.

[0032] Specifically, the storage and adjustment device 5 further includes a rubber strip 55 , and the rubber strips 55 are installed on both sides adjacent to each other between the two clamping frames 54 .

[0033] By adopting the above technical solution, the tooling can enhance the friction between the clamping frame 54 and the steel rope 4 through the rubber strip 55, thereby ensuring that the two clamping frames 54 can clamp the steel rope 4 normally and better meet the work needs.

[0034] When this embodiment is in use, when it is necessary to adjust the overall length of the steel rope 4, the staff puts the excess part of the steel rope 4 into the storage box 51 in the storage adjustment device 5, and then rotates the two second knobs 52 respectively, thereby driving the two screw rods 53 to rotate. The screw rods 53 are threadedly connected to the clamping frame 54, and the inner bottom surface of the clamping frame 54 and the outer bottom surface of the storage box 51 are tightly attached to each other, so the two screw rods 53 drive the two clamping frames 54 and the rubber strips 55 thereon to move, and then clamp the steel rope 4, preventing the part of the steel rope 4 in the storage box 51 from leaving the storage box 51, thereby adjusting the overall length of the steel rope 4 to better meet the work needs in different situations.

[0035] The working principle and use process of the utility model are as follows: when the work of the bridge erecting machine requires the use of a tool, the worker screws the two screws 23 in the supporting fixture 2 to disengage it from the threaded hole 26 on the inner column 24, and then the worker pulls the two outer sleeves 21 to move, thereby adjusting the overall length of the two outer sleeves 21 and the inner column 24, and then adjusting the movable range of the steel rope 4, and then the worker rotates the two screws 23 in the opposite direction to connect them with the corresponding threaded holes 26, and then the worker clamps the two fixing frames 1 on the protective wall, and then rotates the two rotating plates 8 respectively, thereby driving the two second The screw rod 7 rotates, the second screw rod 7 is threadedly connected to the fixing frame 1, the second screw rod 7 is bearing-connected to the clamping plate 6, and the outer top surface of the clamping plate 6 is in close contact with the inner top surface of the fixing frame 1, so the two second screw rods 7 respectively drive the two clamping plates 6 to move, and then cooperate with the two fixing frames 1 to clamp the protective wall, thereby fixing the positions of the two fixing frames 1. The staff can wear the safety belt 3 and then use it to prevent the staff from accidentally falling when working at high altitudes. When it is necessary to prevent the steel rope 4 and the outer frame 25 and other structures from moving outside the two outer sleeves 21 and the inner column 24, the staff should wear the safety belt 3 before work. The operator or other staff members rotate the first knobs 222 in the two fixing components 22 respectively during work, thereby driving the two first screws 223 to rotate. The first screws 223 are threadedly connected to the outer frame 25, and the first screws 223 are bearing-connected to the rubber extrusion blocks 221. Therefore, the two first screws 223 drive the two rubber extrusion blocks 221 to move, thereby clamping the outer sleeve 21 or the inner cylinder 24, thereby fixing the position of the outer frame 25, thereby preventing the steel rope 4 and the outer frame 25 from moving outside the two outer sleeves 21 and the inner cylinder 24; when it is necessary to adjust the steel rope 4 When the overall length is adjusted, the staff puts the excess part of the steel rope 4 into the storage box 51 in the storage adjustment device 5, and then rotates the two second knobs 52 respectively, thereby driving the two screw rods 53 to rotate. The screw rods 53 are threadedly connected to the clamping frame 54, and the inner bottom surface of the clamping frame 54 and the outer bottom surface of the storage box 51 are tightly attached to each other, so the two screw rods 53 drive the two clamping frames 54 and the rubber strips 55 thereon to move, and then clamp the steel rope 4, preventing the part of the steel rope 4 in the storage box 51 from leaving the storage box 51, thereby adjusting the overall length of the steel rope 4 to better meet the work needs in different situations.
