DETAILED DESCRIPTION

[0031] The embodiment of the present application discloses a three-dimensional fine-tuning device for the cable guide tube of a cable-stayed bridge. Through the setting of the angle adjustment component 2 and the movement of the adjustment slide 203, the adjustment arm 204 is gradually inclined to a vertical state, so that the connection end of the hosting platform 301 and the adjustment arm 204 can rise, and then the hosting platform 301 can be tilted upward, so that the cable guide tube 7 clamped by the fixed pipe structure 3 can be tilted and adjusted in angle, so that it can be flexibly applied at the construction site and the installation accuracy of the cable guide tube 7 is improved.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 , a three-dimensional fine-tuning device for a cable-stayed bridge cable guide disclosed in an embodiment of the present application includes: an angle adjustment component 2, the angle adjustment component 2 is arranged on one side of the top of a lifting and adjusting platform 1, the angle adjustment component 2 is used to adjust the use angle of the fixed pipe structure 3, the angle adjustment component 2 includes an adjusting screw rod 202, the outer side of the adjusting screw rod 202 is threadedly connected to an adjusting slide 203, the top of the adjusting slide 203 is rotatably provided with an adjusting arm 204, and the two ends of the adjusting screw rod 202 are rotatably provided with a fixed seat sliding shell 201, the fixed seat sliding shell 201 is fixedly provided on the top of the lifting and adjusting platform 1, and the rotation of the adjusting screw rod 202 is used to drive the adjusting slide 203 to move, which is suitable for adjusting the angle between the adjusting arm 204 and the lifting and adjusting platform 1 by moving the adjusting slide 203.

[0035] By rotating the adjusting screw 202 in the angle adjustment assembly 2, the adjusting slide 203 slides on the inner side of the fixed seat sliding shell 201, thereby changing the angle between the adjusting connecting arm 204 and the fixed seat sliding shell 201. The larger the angle, the greater the inclination angle of the cable guide tube 7, thereby achieving the effect of adjusting the installation angle of the cable guide tube 7, so that it can be flexibly used at the construction site.

[0036] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , also includes a fixed pipe structure 3, the fixed pipe structure 3 is arranged at the top of the lifting and adjusting platform 1, the fixed pipe structure 3 is used to clamp the fixed rope guide tube 7, the fixed pipe structure 3 includes a hosting platform 301, the hosting platform 301 is rotatably connected to the adjusting arm 204, the hosting platform 301 is rotatably arranged on the other side of the top of the lifting and adjusting platform 1, the top of the hosting platform 301 is provided with a receiving groove 3011, the inner side of the receiving groove 3011 is symmetrically fixed with a fixed sliding shell 3012, the inner side of the receiving groove 3011 is slidingly provided with a taking over platform 302, the taking over platform 302 is provided with a slide rail at the position of the fixed sliding shell 3012, and the top of the hosting platform 301 and the taking over platform 302 are arranged with an arc surface.

[0037] Among them, when the taking over platform 302 descends and rises, it slides with the fixed sliding shell 3012 through the sliding rail, so that the taking over platform 302 can only move in the vertical direction, and the top of the hosting platform 301 and the taking over platform 302 are set as arc surfaces, which makes it convenient for the cable guide tube 7 to be always located in the middle of the top of the hosting platform 301, thereby improving the accuracy of the installation of the cable guide tube 7.

[0038] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The bottom end of the takeover platform 302 is symmetrically rotatably provided with a driving pressure connecting plate 303, and the other end of the driving pressure connecting plate 303 is rotatably provided with a driving gear plate 304, and the top of the driving gear plate 304 is meshed with a connecting gear 305, and a connecting pressure plate 306 is fixedly provided on the outer side of the connecting gear 305, and the other end of the connecting pressure plate 306 is rotatably provided with a pipe clamping arc plate 307, and the side of the pipe clamping arc plates 307 close to each other is an arc surface, and the side of the pipe clamping arc plates 307 close to each other is provided with anti-slip grooves, and the two ends of the connecting pressure plate 306 are rotatably provided with side brackets 308, and the bottom end of the driving gear plate 304 is slidably provided with a side connecting platform 309, and the side bracket 308 is fixedly provided on the top of the side connecting platform 309, and the side connecting platform 309 is fixedly provided at the bottom end of the hosting platform 301;

[0039] The gravity of the cable guide tube 7 causes the connecting platform 302 to be pressed down. The downward pressure of the connecting platform 302 will gradually increase the angle between the two driving and pressure connecting plates 303, so that the driving gear plate 304 will be driven to move by the change of the driving and pressure connecting plate 303. The movement of the driving gear plate 304 drives the connecting gear 305 to rotate, and the rotation of the connecting gear 305 drives the connecting pressure plate 306 to move. The angle between the connecting pressure plate 306 and the driving gear plate 304 will gradually decrease, and the pipe clamping arc plate 307 set at the other end of the connecting pressure plate 306 will fit the outer side of the cable guide tube 7, so that the two pipe clamping arc plates 307 form a clamping force to fix the cable guide tube 7, which is more stable when adjusting the cable guide tube 7 and reduces the use of external lifting equipment.

[0040] Among them, the latch assembly includes a connecting round block 313, which is fixedly arranged at the other end of the lower guide rod 312, and a receiving groove 3131 is symmetrically provided on the outer side of the connecting round block 313, and a return spring 3141 is fixedly provided on the inner side of the receiving groove 3131, and a locking block 314 is fixedly provided on the other end of the return spring 3141, and the locking block 314 is slidably provided on the inner side of the receiving groove 3131, and the side of the locking blocks 314 away from each other is an inclined surface setting, and a fixed cylindrical shell 315 is fixedly provided at the bottom end of the bottom cover shell 311, and a sliding groove 3151 is symmetrically provided on the outer side of the fixed cylindrical shell 315, and a fixing ring 316 is fixedly provided on the inner side of the fixed cylindrical shell 315, and the fixing ring 316 is located at the top of the locking block 314.

[0041] When the locking block 314 is in contact with the fixing ring 316, the locking block 314 enters the receiving groove 3131 through the inclined surface set on the side of the locking block 314 away from each other, and the return spring 3141 is compressed. When the locking block 314 enters between the fixing ring 316 and the movable ring plate 317, the elastic force of the return spring 3141 allows the locking block 314 to be released, thereby preventing the lower guide rod 312 from being pulled upward, thereby forming a locked state, making the pipe clamping arc plate 307 more stable when clamping.

[0042] Specifically, a movable ring plate 317 is provided at the bottom end of the locking block 314, and the movable ring plate 317 is slidably provided on the inner side of the fixed cylinder shell 315. An extension plate is symmetrically provided on the outer side of the movable ring plate 317, and the extension plate is slidably provided on the inner side of the slide groove 3151. A guide rod 318 is fixedly provided at the bottom end of the extension plate, and a bottom connecting plate is fixedly provided at the other end of the guide connecting rod 318. A return plate spring 319 is fixedly provided at the top end of the bottom connecting plate, and the return plate spring 319 is fixedly provided at the bottom end of the fixed cylinder shell 315.

[0043] After the cable guide tube 7 is installed and fixed, it is necessary to separate the fixed tube structure 3 from the cable guide tube 7. The bottom connecting plate can be pushed upward so that the guide rod 318 can drive the movable ring plate 317 to move upward and the locking block 314 can enter the receiving groove 3131. At this time, the angle of the hosting platform 301 is slowly adjusted through the angle adjustment component 2 to reduce the angle between the hosting platform 301 and the lifting adjustment platform 1, and the connecting platform 302 and the lower guide rod 312 will gradually rise due to the elastic force of the return spring 310, so that the pipe clamping arc plate 307 releases the cable guide tube 7, so that the device can be disassembled.

[0044] Example 2:

[0045] Reference Figure 1 and Figure 7 The bottom end of the lifting and adjusting platform 1 is provided with a height adjustment structure 4, which includes a sliding platform 401. The top of the sliding platform 401 is symmetrically rotated with a first expansion connecting plate 402, and a second expansion connecting plate 403 is provided above the first expansion connecting plate 402. A connecting frame 405 is rotatably provided at the same end of the first expansion connecting plate 402 and the second expansion connecting plate 403. A double-threaded rod 406 is passed through and threadedly connected to one side of the connecting frame 405, and a symmetrical thread line is provided on the outer side of the double-threaded rod 406. A hanging plate 404 is rotatably provided on both sides of the second expansion connecting plate 403, and the connecting frame 405 is fixedly provided at the bottom end of the lifting and adjusting platform 1.

[0046] When it is necessary to adjust the installation height of the cable guide tube 7, directly rotate the double-threaded rod 406 in the height adjustment structure 4 to lengthen the distance between the connecting frames 405, thereby driving the first expansion connecting plate 402 and the second expansion connecting plate 403 to open under the movement of the connecting frame 405, and the angle between the first expansion connecting plate 402 and the second expansion connecting plate 403 becomes larger, thereby increasing the height of the lifting adjustment platform 1, so that the height of the fixed pipe structure 3 and the cable guide tube 7 clamped by it can be adjusted, so as to match the adjusted angle of the cable guide tube 7, making the cable guide tube 7 more accurate during installation.

[0047] Reference Figure 1 、 Figure 7 and Figure 8 The bottom end of the sliding platform 401 is slidably provided with an upper connecting platform 5, the bottom end of the sliding platform 401 is threadedly connected to a first screw rod 501, and the first screw rod 501 is rotatably provided on both sides of the top of the upper connecting platform 5, and the bottom end of the upper connecting platform 5 is slidably provided with a lower connecting platform 6, the bottom end of the upper connecting platform 5 is threadedly connected to a second screw rod 601, and the second screw rod 601 is rotatably provided on both sides of the top of the lower connecting platform 6, and the lower connecting platform 6 is fixed around the embedded installation position of the cable guide tube 7 by bolts.

[0048] When adjusting the lateral position of the cable guide tube 7, the first screw rod 501 is rotated, and the rotation of the first screw rod 501 can drive the sliding platform 401 to move. When adjusting the longitudinal position of the cable guide tube 7, the second screw rod 601 is rotated, and the rotation of the second screw rod 601 can drive the upper connecting platform 5 to move, thereby adjusting the longitudinal and transverse positions of the cable guide tube 7, further improving the installation accuracy of the cable guide tube 7.

[0049] Working principle: The device is installed around the pre-buried installation position of the cable guide tube 7 through the lower connecting platform 6. The cable guide tube 7 is placed on the top of the hosting platform 301. The longer end of the cable guide tube 7 is the end that is obliquely inserted into the bridge structure. When the cable guide tube 7 contacts the connecting platform 302 and the gravity of the cable guide tube 7 causes the connecting platform 302 to be pressed down, the downward pressure of the connecting platform 302 will gradually increase the angle between the two driving pressure connecting plates 303, so that the driving gear plate 304 will be driven to move by the change of the driving pressure connecting plate 303. The movement of the driving gear plate 304 drives the connecting gear 305 to rotate, and the rotation of the connecting gear 305 drives the connecting pressure plate 306 to move. The angle between the connecting pressure plate 306 and the driving gear plate 304 will gradually decrease, and the pipe clamping arc plate 307 provided at the other end of the connecting pressure plate 306 will fit the outer side of the cable guide tube 7. Thus, the two pipe clamping arc plates 307 form a clamping force to fix the cable guide tube 7, which is more stable when adjusting the cable guide tube 7 and reduces the use of external lifting equipment, making the installation of the cable guide tube 7 easier.

[0050] The take-over platform 302 is slidably engaged with the fixed sliding housing 3012 via a slide rail, so that the take-over platform 302 can only move in the vertical direction. The tops of the take-over platform 301 and the take-over platform 302 are curved surfaces, which facilitates the cable guide 7 to always be located in the middle of the top of the take-over platform 301, thereby improving the accuracy of the cable guide 7 during installation.

[0051] When the locking block 314 is in contact with the fixing ring 316, the locking block 314 enters the receiving groove 3131 through the inclined surface provided on the side of the locking block 314 moving away from each other, and the return spring 3141 is compressed. When the locking block 314 enters between the fixing ring 316 and the movable ring plate 317, the elastic force of the return spring 3141 releases the locking block 314, thereby preventing the lower guide rod 312 from being pulled upward, thereby forming a locked state, making the pipe clamping arc plate 307 more stable when clamping;

[0052] When adjusting the installation angle of the cable guide tube 7, the adjusting screw 202 in the angle adjustment assembly 2 is rotated to make the adjusting slide 203 slide inside the fixed seat sliding housing 201, thereby changing the angle between the adjusting connecting arm 204 and the fixed seat sliding housing 201. The larger the angle, the greater the inclination angle of the cable guide tube 7, thereby achieving the effect of adjusting the installation angle of the cable guide tube 7, and allowing for flexible application at the construction site;

[0053] After the cable guide tube 7 is adjusted and fixed to the bridge structure, the bottom connecting plate is pushed upward, so that the guide rod 318 can drive the movable ring plate 317 to move upward, and the locking block 314 enters the receiving groove 3131. At this time, the angle of the hosting platform 301 is slowly adjusted by the angle adjustment component 2, so that the angle between the hosting platform 301 and the lifting adjustment platform 1 becomes smaller, and the connecting platform 302 and the lower guide rod 312 are gradually raised by the elastic force of the return spring 310, so that the clamping arc plate 307 releases the cable guide tube 7, so that the device can be disassembled;

[0054] Furthermore, when it is necessary to adjust the installation height of the cable guide tube 7, the double-threaded screw rod 406 in the height adjustment structure 4 is directly rotated to lengthen the distance between the connecting frames 405, thereby driving the first expansion connecting plate 402 and the second expansion connecting plate 403 to open under the movement of the connecting frame 405, and the angle between the first expansion connecting plate 402 and the second expansion connecting plate 403 becomes larger, thereby increasing the height of the lifting adjustment platform 1, so that the height of the fixed pipe structure 3 and the cable guide tube 7 clamped therein can be adjusted. When adjusting the lateral position of the cable guide tube 7, the first screw rod 501 is rotated, and the rotation of the first screw rod 501 can drive the sliding platform 401 to move. When adjusting the longitudinal position of the cable guide tube 7, the second screw rod 601 is rotated, and the rotation of the second screw rod 601 can drive the upper connecting platform 5 to move, thereby adjusting the longitudinal and transverse positions of the cable guide tube 7, thereby further improving the installation accuracy of the cable guide tube 7.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
