Description

Technical Field

[0001] This application relates to the field of bridge construction, and in particular to a prefabricated steel tower assembly frame system. Background Technology

[0002] Due to the aesthetic appeal of steel arch cable-stayed bridges, their design and application are becoming increasingly widespread. However, due to the unique structural design and limitations of on-site construction conditions, the installation of steel arch towers may not be possible using conventional hoisting methods. Generally, the steel arch towers are first assembled on the bridge deck and then rotated to their designed location. Two common rotation methods are used: one is using the tower's vertical lifting mechanism for rotation, and the other is using a tripod lifting platform for rotation. Both methods allow for good control over the forming accuracy of the steel arch tower during vertical rotation; most of the steel arch tower structure can be welded on the ground before construction, facilitating on-site welding and quality inspection; high-altitude work is avoided, and investment is reduced.

[0003] During the vertical rotation of the steel arch tower, the supporting frame needs to be pre-assembled on the bridge's steel box girder. Multiple parallel supporting frames support the steel tower horizontally. During the assembly process, a crane is used to lift each section of the steel tower, and steel pads are used to fine-tune the overall height of the supporting frame to ensure that the top of the supporting frame is on the same straight line, thus ensuring the assembly quality of the steel tower.

[0004] Regarding the aforementioned technologies, the inventors believe that the adjustable height of the steel pad depends on the manufacturing thickness of the steel pad. During the process of adjusting the height of the jig, it is difficult to quickly select a steel pad of suitable thickness. Therefore, it is necessary to repeatedly measure the height of the jig, which makes the adjustment process between the jig and the steel tower cumbersome and results in low support accuracy of the jig for the steel tower. Summary of the Invention

[0005] To reduce the number of height measurements required for the jig, simplify the adjustment process between the jig and the steel tower, and improve the support accuracy of the jig for the steel tower, this application provides a prefabricated steel tower assembly jig system.

[0006] The prefabricated steel tower assembly frame system provided in this application adopts the following technical solution:

[0007] A prefabricated steel tower assembly frame system includes multiple frame bodies for supporting the steel tower. Each frame body includes at least two sets of fixed frames arranged side by side and an adjusting frame for adjusting the distance between the fixed frames and the steel tower. Multiple connecting components for connecting the fixed frames and the adjusting frames are provided between the adjusting frames and the fixed frames. A support frame for connecting the top ends of the multiple adjusting frames is provided between the multiple adjusting frames. The support frame abuts against the surface of the steel tower through the adjusting frames.

[0008] By adopting the above technical solution, the retractable adjustment frame can be used to adjust the position according to the actual standard position when there is an error between the top of the jig body and the steel tower assembly position. The retractable adjustment frame is more precise in adjusting the height, thus providing more stable support for the steel tower, reducing the number of height measurements of the jig, simplifying the adjustment process between the jig and the steel tower, and improving the support accuracy of the jig for the steel tower.

[0009] Optionally, the adjusting frame includes an upper frame and a lower frame that are slidably connected together. The upper frame is provided with a plurality of sliding rods, which are inserted into and slidably connected to the lower frame. A first telescopic push-pull device is provided between the upper frame and the lower frame. The distance between the upper frame and the lower frame is adjusted by the first telescopic push-pull device. Each sliding rod is also provided with a locking component, and the relative positions between the upper frame and the lower frame are locked together by the locking component.

[0010] By adopting the above technical solution, the telescopic push-pull device has a large load capacity, can effectively make dynamic adjustments between the upper and lower frames, and can stably support the steel tower during the assembly process. At the same time, the stepless adjustment of the telescopic push-pull device can improve the accuracy of the overall height of the jig body and improve the support effect on the steel tower. In addition, the locking component can transfer part of the load borne by the telescopic push-pull device between the upper and lower frames, thereby increasing the stability of the connection between the upper and lower frames.

[0011] Optionally, the locking assembly includes multiple locking blocks for fixing the upper frame to the lower frame, a drive screw for sliding the locking blocks, and a drive component for rotating the drive screw. The inner wall of the lower frame has multiple first locking teeth arranged circumferentially along the lower frame. The side wall of the locking block has multiple second locking teeth that match the first locking teeth. A drive ring is threaded onto the drive screw. A connecting rod is rotatably arranged between the drive ring and each locking block. The locking block moves away from the drive screw via the connecting rod and engages the first locking teeth with the second locking teeth.

[0012] By adopting the above technical solution, the upper and lower frames are locked by using a drive screw to push the locking blocks. The overall installation space is smaller, and the drive screw has stronger synchronization in driving multiple locking blocks, which can better support the upper and lower frames. At the same time, the first and second locking teeth can limit the relative position between the upper and lower frames, and the first and second locking teeth can support the upper frame, reducing the settlement of the upper frame.

[0013] Optionally, the side wall of the connecting rod is provided with a guide portion for guiding the locking block to move toward the side wall of the lower frame.

[0014] By adopting the above technical solution, the guide part can make the movement direction of the locking block more precise, and at the same time provide a certain support effect for the locking block, so that the locking block and the upper frame can withstand more loads and improve the connection strength between the upper frame and the lower frame.

[0015] By adopting the above technical solution, a sensor group for detecting the top position of the two frames is provided between the two upper frames of the two sets of frame bodies located on both sides of the bridge. The sensor group includes a transmitter for transmitting signals and a receiver for receiving signals, and the transmitter and the receiver are respectively located on the two frame bodies.

[0016] By adopting the above technical solution, the sensor groups on the two sets of upper frame can detect the error between the two sets of jigs of the same height, thereby reducing the error between the two sets of jig bodies, thereby reducing the deformation of the two steel tower arms due to the different heights during the steel tower assembly process, and thus improving the steel tower assembly accuracy.

[0017] Optionally, the fixing frame includes multiple separately arranged frame segments, each frame segment including multiple uprights and multiple diagonal braces, and the uprights on two adjacent frame segments are connected end to end by the connecting component.

[0018] By adopting the above technical solution, the fixture frame can be divided into multiple sections by using multiple separately set fixture frames, which facilitates the transportation of the fixture frame body. At the same time, the connection components can simplify the connection method between two fixture frames, making the fixture frame easier to assemble and disassemble.

[0019] Optionally, a connecting plate is fixedly connected to the end face of the column. The diameter of the connecting plate is larger than the diameter of the column. The connecting assembly includes a connecting block and a connecting groove that matches the connecting plate at both ends of the connecting block. The connecting plate can extend into the connecting groove and be connected to the connecting block by a threaded connector.

[0020] By adopting the above technical solution and using a connecting block with a connecting groove, the side wall of the connecting groove provides a certain degree of bending resistance to the connecting plate after it enters the connecting block. This ensures the strength of the vertical connection while enhancing the bending strength of the frame body and improving the support stability of the frame body.

[0021] Optionally, the connecting groove is provided with a plurality of positioning protrusions, and the connecting plate is provided with positioning grooves that match the positioning protrusions.

[0022] By adopting the above technical solution, the positioning protrusion can reduce the change in angle between the connecting block and the connecting plate during the assembly process, thereby facilitating the connection of the connecting plate and the connecting block using threaded fasteners, reducing errors and safety hazards caused by manual alignment.

[0023] Optionally, one end of the support frame along its length is rotatably connected to the upper frame. An adjustment assembly for adjusting the angle of the support frame is provided between the adjustment frame and the support frame. The adjustment assembly includes a second telescopic push-pull device for pushing the support frame to rotate and multiple support plates for limiting the rotation of the adjustment frame to a horizontal position. The multiple support plates are arranged side by side, and one end of each support plate is rotatably connected to the adjustment frame. A transversely arranged support beam is provided on the support frame. Multiple locking slots are provided on the support plates to engage with the support beams. The support beams are engaged into the locking slots at different positions to limit the rotation of the support plates. An angle detection device for detecting the angle between the support frame and the horizontal plane is provided on the support frame.

[0024] By adopting the above technical solution, the rotation angle of the support frame can be detected using an angle detection device, thereby making the support angle of multiple adjustment components in the same group more accurate, reducing the time for manual measurement using instruments, improving adjustment efficiency and accuracy. The second telescopic push-pull device can drive the support frame to rotate while providing stable support force, thus providing stable support for the steel tower. The rotatable support frame can support the steel tower whether it is horizontally or inclined, thereby improving the versatility of the frame. At the same time, the support plate and support beam can support the angular position of the support frame, thereby reducing the workload of the second telescopic push-pull device and improving the stability of the support frame.

[0025] Optionally, the support frame is provided with another set of sensors for detecting the straightness of the support frame on two adjacent jig bodies along the tilt direction of the steel tower.

[0026] By adopting the above technical solution, the sensor group can detect the degree of collinearity of the tilt direction of two adjacent jig bodies in the same group, so that the top end faces of multiple jig bodies in each group can be kept at the same tilt height as much as possible, thereby reducing the uneven support force on the steel tower due to different heights.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The telescopic adjustment frame allows for real-time adjustment based on the actual standard position when there is an error between the top of the jig body and the steel tower assembly position. Furthermore, the telescopic adjustment frame provides more precise height adjustment, thereby providing more stable support for the steel tower. This reduces the number of times the jig height needs to be measured, simplifies the adjustment process between the jig and the steel tower, and improves the support accuracy of the jig for the steel tower.

[0029] The upper and lower frames are locked by using a drive screw to push the locking blocks, which reduces the overall installation space. At the same time, the drive screw has stronger synchronization in driving multiple locking blocks, which can better support the upper and lower frames. The first and second locking teeth can limit the relative position between the upper and lower frames and support the upper frame, reducing the settlement of the upper frame.

[0030] An angle detection device can detect the rotation angle of the support frame, thereby making the support angle of multiple adjustment components in the same group more accurate, reducing the time spent on manual measurement with instruments, and improving adjustment efficiency and accuracy. The second telescopic push-pull device can drive the support frame to rotate while providing stable support force, thus providing stable support for the steel tower. The rotatable support frame can support the steel tower whether it is horizontal or inclined, thereby improving the versatility of the frame. At the same time, the support plate and support beam can support the angular position of the support frame, thereby reducing the workload of the second telescopic push-pull device and improving the stability of the support frame.

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] Example 1:

[0041] This application discloses a prefabricated steel tower assembly frame system.

[0042] Reference Figure 1 A prefabricated steel tower assembly frame system includes multiple frame bodies 1 that are anchored and fixedly connected to the surface of the steel tower. The multiple frame bodies 1 are divided into two groups, and the two groups of frame bodies 1 are respectively fixedly connected to both sides of the steel tower. The frame bodies 1 in each group are arranged along the length of the bridge deck and support the steel tower.

[0043] refer to Figure 2 The frame body 1 includes at least two sets of fixed frames 2 connected to the steel tower and an adjusting frame 3 for adjusting the overall height of the frame body 1. A connecting component 4 is provided between the adjusting frame 3 and the fixed frame 2, and the adjusting frame 3 is detachably connected to the top of the fixed frame 2 through the connecting component 4. The tops of multiple adjusting frames 3 are simultaneously fixedly connected to support frames 11 for directly supporting the steel tower. The support frames 11 are simultaneously fixedly connected to the tops of multiple adjusting frames 3, so that the support frames 11 can be raised or lowered through multiple adjusting frames 3, thereby changing the overall height of the frame body 1.

[0044] refer to Figure 2 The fixed frame 2 includes multiple frame segments 21 spliced ​​together in a vertical direction, and adjacent frame segments 21 are connected together by connecting components 4. The support height of the frame body 1 on the steel tower is adjusted by the number of frame segments 21 and the height of the adjusting frame 3.

[0045] refer to Figure 2 , Figure 3The frame section 21 includes multiple vertically arranged columns 211. In this embodiment, four columns 211 are used as an example, arranged side by side to form a rectangle. Diagonal braces 212 are welded and fixed between adjacent columns 211 to improve the strength of the frame section 21. Connecting plates 213 are welded and fixed to both ends of each column 211 along its length. The connecting assembly 4 fixes the two frame sections 21 together through the connecting plates 213 on the two frame sections 21. Multiple identical connecting plates 213 are fixedly connected to the bottom end of the adjusting frame 3. The adjusting frame 3 is detachably connected to the uppermost frame section 21 and to the two frame sections 21 through the connecting assembly 4.

[0046] refer to Figure 2 , Figure 3 The connecting component 4 includes a connecting block 41 and multiple fixing bolts 42. The cross-sectional area of ​​the connecting block 41 is larger than that of the connecting plate 213. Both the top and bottom faces of the connecting block 41 have connecting grooves 411 that match the connecting plate 213. The connecting plates 213 on two adjacent frame sections 21 can be inserted into the connecting block 41 through the connecting grooves 411. The fixing bolts 42 pass through both the connecting block 41 and the two connecting plates 213, thus fixing the two connecting plates 213 to the connecting block 41 together.

[0047] refer to Figure 2 , Figure 3 Multiple positioning protrusions 43 are integrally formed on the end face of the connecting groove 411, and multiple positioning grooves 2131 matching the positioning protrusions 43 are formed on the end face of the connecting plate 213 facing the connecting block 41. When the connecting plate 213 enters the connecting groove 411, the positioning protrusions 43 can extend into the positioning grooves 2131, so that the two adjacent jig sections 21 and the connecting block 41 can be quickly aligned with the accurate installation position.

[0048] refer to Figure 2 , Figure 4The adjusting frame 3 includes a separate upper frame 31 and a lower frame 32. Multiple sliding rods 33 are fixedly connected to the bottom end face of the upper frame 31. One end of each sliding rod 33 is fixedly connected to the upper frame 31, and the other end extends into the lower frame 32, thus allowing the upper frame 31 to slide together with the lower frame 32 via the sliding rods 33. Multiple first telescopic push-pull devices 34, which are hydraulic cylinders, are fixedly connected to the upper frame 31 and the lower frame 32. The bottom end of each first telescopic push-pull device 34 is fixedly connected to the lower frame 32, and the top end is fixedly connected to the upper frame 31. When the first telescopic push-pull device 34 extends, it moves the upper frame 31 away from the lower frame 32, thereby increasing the height of the adjusting frame 3. The sliding rod 33 is equipped with a locking component 35. When the upper frame 31 moves to the desired position, the relative positions of the upper frame 31 and the lower frame 32 are locked together by the locking component 35.

[0049] refer to Figure 4 , Figure 5 The locking assembly 35 includes multiple locking blocks 351 for abutting against the lower frame 32, a drive screw 352 for pressing the locking blocks 351 together, and a drive motor 353 for rotating the drive screw 352. The multiple locking blocks 351 are slidably connected inside the sliding rod 33, and are arranged circumferentially at intervals along the axis of the sliding rod 33, and in multiple sets at intervals along the axial direction of the sliding rod 33. In this embodiment, two sets of locking blocks 351 are used as an example. A locking hole 331 is provided at the position opposite to each locking block 351 on the sliding rod 33, allowing the locking block 351 to extend out of the locking hole 331 and abut against the lower frame 32.

[0050] refer to Figure 4 , Figure 5 Guide portions 332 are fixedly connected to the four corners of the locking hole 331. The length direction of the guide portions 332 is perpendicular to the side wall of the sliding rod 33. The guide portions 332 are arranged in a cross-sectional shape extending along the end corner of the locking hole 331, so that the four guide portions 332 form a channel that surrounds the locking block 351, allowing the locking block 351 to slide between the multiple guide portions 332 along the length direction of the guide portions 332.

[0051] Multiple first locking teeth 321 are provided on the side wall of the inner hole of the lower frame 32. The length direction of the first locking teeth 321 is arranged along the circumference of the inner hole of the lower frame 32, and the multiple first locking teeth 321 are spaced apart along the axial direction of the inner hole of the lower frame 32. Multiple second locking teeth 3511 are fixedly connected to the side wall of the locking block 351 facing the first locking teeth 321. When the locking block 351 is close to the first locking teeth 321, the first locking teeth 321 and the second locking teeth 3511 can mesh with each other, thereby restricting the movement of the upper frame 31 along the axial direction of the lower frame 32.

[0052] refer to Figure 4 , Figure 5 The drive screw 352 is rotatably connected inside the sliding rod 33, and the length direction of the drive screw 352 is the same as the length direction of the sliding rod 33. The housing of the drive motor 353 is fixedly connected to the sliding rod 33, and the output end of the drive motor 353 is coaxially fixed to the drive screw 352.

[0053] refer to Figure 4 , Figure 5 Multiple drive rings 354 are threaded onto the drive screw 352. The number of drive rings 354 is the same as the number of sets of locking blocks 351, and they are one-to-one. In each set of multiple locking blocks 351, each locking block 351 is rotatably connected to a drive ring 354 by a connecting rod 355. One end of the connecting rod 355 is hinged to the locking block 351, and the other end of the connecting rod 355 is hinged to the side wall of the drive ring 354. When the drive motor 353 drives the drive screw 352 to rotate, the drive screw 352 drives the drive rings 354 to move along the axis of the drive screw 352, and drives the connecting rod 355 to push the locking blocks 351 toward the side wall of the lower frame 32, so that the locking blocks 351 press against the side wall of the lower frame 32, and lock the upper frame 31 and the lower frame 32 together by friction.

[0054] The implementation principle of the prefabricated steel tower assembly frame system in this application embodiment is as follows: During the horizontal assembly of the steel tower, multiple frame segments 21 are first connected together on the box girder of the bridge using connecting components 4, and the adjusting frame 3 is fixed to the top of the fixed frame 2 through the connecting components 4. Then, the first telescopic push-pull device 34 is adjusted so that the adjusting frame 3 is extended or shortened to the required height, thereby using the support frame 11 to support the steel tower, thus completing the installation of the frame system.

[0055] Example 2:

[0056] This application discloses a prefabricated steel tower assembly frame system.

[0057] The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 6 , Figure 7An adjustment assembly 5 is provided between the upper frame 31 and the support frame 11, and the support frame 11 is hinged to the top of the adjustment frame 3 via the adjustment assembly 5. The height of the multiple jig bodies 1 gradually increases along the tilt direction of the steel tower, so that when the steel tower is assembled at an incline, the support frame 11 can support the steel tower according to the assembly angle required for the construction of the steel tower.

[0058] refer to Figure 7 The adjusting assembly 5 includes a second telescopic push-pull device 51 that drives the support frame 11 to rotate, and multiple support plates 52 that maintain the support frame 11 at a certain angle. The second telescopic push-pull device 51 is a hydraulic cylinder. One end of the support frame 11 along its length is hinged to the top end face of the upper frame 31 via a horizontal axis. The bottom end of the second telescopic push-pull device 51 is hinged to the upper frame 31, and the top end of the second telescopic push-pull device 51 is hinged to the support frame 11. When the second telescopic push-pull device 51 extends, the angle between the support frame 11 and the horizontal plane increases; when the second telescopic push-pull device 51 shortens, the angle between the support frame 11 and the horizontal plane decreases, thereby achieving adjustment of the tower support angle.

[0059] The surface of the support plate 52 is perpendicular to the support frame 11, and one end of the support plate 52 along its length is rotatably connected to the support frame 11. A horizontally arranged support beam is fixedly connected to the lower frame 32, and the length direction of the support beam is the same as the axis of rotation of the support frame 11. Multiple snap-fit ​​grooves 531 are provided on the side wall of the support plate 52. The snap-fit ​​grooves 531 are set at a certain angle to the side wall of the support plate 52, and multiple snap-fit ​​grooves 531 are arranged at intervals along the length direction of the support plate 52. When the second telescopic push-pull device 51 extends, the snap-fit ​​groove 531 rotates to be opposite to the support rod, the second telescopic push-pull device 51 shortens, and the snap-fit ​​groove 531 snaps onto the outside of the support beam, thereby fixing the support frame 11 by the angle of the snap-fit ​​groove 531.

[0060] An angle sensor 53 for detecting the rotation angle of the support frame 11 is fixedly installed on the support frame 11. During the rotation of the support frame 11 by the second telescopic push-pull device 51, the angle sensor 53 can be used to check whether the rotation angle of multiple support frames 11 meets the requirements.

[0061] refer to Figure 7A sensor group 6, which detects the straightness of two adjacent support frames 11, is fixedly installed on the support frame 11. The sensor group 6 uses a laser sensor. The sensor group 6 includes a transmitter 61 for transmitting signals and a receiver for receiving signals. The transmitter 61 and the receiver are respectively fixedly connected to both ends of the support frame 11 along its length, and the line connecting the transmitter 61 and the receiver is parallel to the length of the support frame 11. When one of the support frames 11 at the top of the frame body 1 rotates to the required angle and is adjusted to the required height using the adjusting frame 3, the support frames 11 on the adjacent frame body 1 on the same side of the bridge rotate to the same angle and are adjusted in height using the adjusting frame 3 until the receiver receives the signal from the transmitter 61 on the adjacent frame body 1, that is, the top faces of the two adjacent support frames 11 are on the same inclined straight line.

[0062] refer to Figure 7 In the two sets of frame bodies 1 located on both sides of the bridge, another set of sensor groups 6 is fixedly installed between the upper frame bodies 31 on the two frame bodies 1 at the same height. The transmitter 61 and receiver in the other set of sensor groups 6 are respectively fixedly connected to the opposite side walls of the two upper frame bodies 31. When one of the two frame bodies 1 is in the correct position, the upper frame body 31 at the top of the other frame body 1 is adjusted until the transmitter 61 is opposite to the receiver, so that the two opposing frame bodies 1 in the two sets of frame bodies 1 are at the same height.

[0063] The implementation principle of the prefabricated steel tower assembly jig system in this application embodiment is as follows: During the tilting assembly of the steel tower, firstly, the jig body 1 with the lowest height is fixedly connected to the steel tower. Multiple jig sections 21 are connected together using connecting components 4, and the adjusting frame 3 is fixed to the top of the fixed frame 2 through the connecting components 4. Then, the second telescopic push-pull device 51 is used to rotate the support frame 11 to the required angle. Next, the first telescopic push-pull device 34 is adjusted to extend or shorten the adjusting frame 3 to the required height. Next, the jig body 1 with the lowest height in another set of jig bodies 1 is installed using the same method, and the height between the two jig bodies 1 is adjusted using the sensor group 6 between the two jig bodies 1. Then, the jig body 1 with the higher height is installed according to the steel tower assembly progress, and the height between two adjacent jig bodies 1 is detected by the sensor group 6 on the support frame 11 and adjusted in real time, thereby completing the installation of the jig system and supporting the steel tower.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
