Description

Technical Field

[0001] This utility model belongs to the field of transmission line tower erection construction, and mainly relates to a tower segment connection node and segmented tower assembly. Background Technology

[0002] Erection of transmission line towers is a crucial step in power grid construction, characterized by its large workload, high construction difficulty, and numerous technical aspects. Using mobile cranes for transmission line tower erection is a widely applied technique in plains and hilly areas. Crane-based tower erection using docking devices is a relatively new method. This method involves installing docking devices at the docking points of tower sections to achieve automatic aerial docking. Theodolites are used to monitor the center position of the tower section being lifted and ensure proper docking. Workers then climb the tower to connect the sections and disassemble the docking devices, manually detaching the crane's main hook from the section being lifted. Afterward, the workers descend the tower and return to the ground, and the crane begins lifting the next section. Once positioned, workers climb the tower again to connect the sections, disassemble the docking devices, and release the main hook, until all sections are lifted. The main problems with existing crane-based tower erection methods using docking devices include:

[0003] (1) For tower erection construction with many tower sections, construction workers need to climb up and down the tower multiple times, resulting in high labor intensity for high-altitude operations.

[0004] (2) After each tower section is connected, construction workers need to climb to the position where the main hook is attached to the rope of the tower section being lifted to manually unhook the hook. The construction workers have a high workload and high safety risks.

[0005] (3) The relative position of the tower section to be lifted and the tower section already in place needs to be observed by the observer using a theodolite. The observer and the crane operator communicate with each other and the observer assists the crane operator in aligning the tower section to be lifted and the tower section already in place. This results in low construction efficiency. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems that construction workers need to repeatedly climb up and down the tower, and that the tower section needs the assistance of observers to position the suspended tower section, resulting in high labor intensity for construction workers and low efficiency of docking construction. This utility model provides a tower section connection node and segmented tower assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, this utility model provides a tower segment connection node, including an upper tower segment main material and a lower tower segment main material. The upper tower segment main material is equipped with a plurality of rangefinders and a plurality of cameras, both of which are pointed at the lower tower segment main material. Both the rangefinders and cameras are connected to a display.

[0009] A further improvement of this utility model is that a magnet is provided on the side of the rangefinder, and the rangefinder is fixed to the main material of the upper tower section by the magnet.

[0010] A further improvement of this invention is that a magnet is provided on the side of the camera, and the camera is fixed to the main material of the upper tower section by the magnet.

[0011] A further improvement of this utility model is that an auxiliary support platform for the lower tower section is provided on the main material, and the rangefinder and camera are both pointed at the auxiliary support platform for the tower section.

[0012] A further improvement of this utility model is that a tower section connector is provided on the main material of the lower tower section, and a number of bolt holes are opened on the tower section connector. A number of bolt holes corresponding to the bolt holes on the tower section connector are opened on the main material of the upper tower section. The bolt holes on the tower section connector and the bolt holes on the main material of the upper tower section are connected by bolts.

[0013] A further improvement of this invention is that the rangefinder uses an infrared laser rangefinder.

[0014] A further improvement of this invention is that the display has several display areas, each of which is used to display the images captured by the corresponding camera and the data collected by the rangefinder.

[0015] Secondly, this utility model provides a segmented tower assembly, including a tower segment already in place and a tower segment to be hoisted. Several rangefinders and several cameras are fixed on the tower segment to be hoisted. The rangefinders and cameras are all pointed at the tower segment already in place, and the rangefinders and cameras are all connected to a display.

[0016] A further improvement of this utility model is that an auxiliary support platform is provided on the tower section that has been positioned, and the rangefinder and camera on the tower section being hoisted are both pointed at the auxiliary support platform.

[0017] A further improvement of this invention is that the tower section to be lifted is hoisted by a crane, the crane is connected to a lifting rope, and the lifting rope is fixed to the top of the tower section to be lifted.

[0018] A further improvement of this invention is that a release device is provided on the lifting rope.

[0019] A further improvement of this utility model is that the display includes a first display area and a second display area. The first display area includes several display units, each of which is used to display the image captured by the corresponding camera and the data collected by the rangefinder. The second display area is used to display the hook status of the unhooking device.

[0020] A further improvement of this invention is that the rangefinder uses an infrared laser rangefinder.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention utilizes a rangefinder and camera installed on the upper tower section's main structure to monitor and provide real-time feedback on the lower tower section's main structure. Construction workers can view the tower's status on a monitor, reducing the need for repeated climbing and descending of the tower, thus decreasing workload and physical exertion. By reducing repetitive operations and time spent working at height, construction efficiency is significantly improved. The real-time monitoring and feedback system makes the construction process smoother and more continuous, thereby accelerating the construction progress. The rangefinder and camera in this invention provide remote monitoring and measurement functions, eliminating the need for construction workers to perform high-risk operations under the loaded boom, thus improving construction safety.

[0023] This utility model uses a rangefinder and camera to align the positioned tower section and the tower section to be lifted from a high altitude. By combining distance measurement and video, it determines whether the tower section to be lifted has been properly positioned. This eliminates the need for construction personnel to climb to the lifting point to manually unhook the tower, avoiding the construction risks caused by incomplete unhooking during boom movement. It effectively reduces the labor intensity of construction personnel, reduces the safety risks of tower assembly construction, and improves the level of intelligence in tower assembly construction.

[0024] Furthermore, this invention includes a release device that can be controlled based on data from a rangefinder and camera, and provides feedback on the completion of the opening and closing of the hook. This effectively improves tower erection efficiency, reduces safety risks during tower erection, and enhances the level of intelligence in tower erection. Attached Figure Description

[0029] To further understand the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of the invention.

[0030] The assembly of the bottom tower section includes ground assembly of the tower section and installation and assembly of the auxiliary support platform for the bottom tower section. During the ground assembly stage, all tower sections are assembled using a small-tonnage crane. When the tower has two sections, the lower section is the bottom tower section, and the upper section is the top tower section. When the tower has three or more sections, the lowermost section is the bottom tower section, the uppermost section is the top tower section, and the remaining sections are intermediate tower sections. After all tower sections are assembled, the auxiliary support platform, the lower tower section main material, and the tower section connectors are installed at the upper ends of the main members at the four corners of the bottom tower section using the connecting bolt holes. A schematic diagram of the installation of a single main member is shown below. Figure 1 As shown. Then, the bottom tower section was assembled.

[0031] Example 1:

[0032] See Figure 1 A tower segment connection node includes an upper tower segment main member 1 and a lower tower segment main member 5. The upper tower segment main member 1 is equipped with several rangefinders 2 and several cameras 6, both of which are connected to a display 12. The lower tower segment main member 5 is equipped with a tower segment auxiliary support platform 4, and both the rangefinders 2 and cameras 6 are pointed towards the tower segment auxiliary support platform 4.

[0033] The lower tower section main material 5 is provided with a tower section connector 3, which has several bolt holes. The upper tower section main material 1 has several bolt holes corresponding to the bolt holes on the tower section connector 3. The bolt holes on the tower section connector 3 and the bolt holes on the upper tower section main material 1 are connected by bolts.

[0034] Preferably, a magnet is provided on the side of the rangefinder 2, and the rangefinder 2 is fixed to the main material 1 of the upper tower section by the magnet. A magnet is provided on the side of the camera 6, and the camera 6 is fixed to the main material 1 of the upper tower section by the magnet.

[0035] Preferably, the rangefinder 2 is an infrared laser rangefinder.

[0036] Preferably, the display 12 has several display areas, each display area being used to display the images captured by the corresponding camera 6 and the data collected by the rangefinder 2.

[0037] During operation, several rangefinders 2 and several cameras 6 are installed on the upper tower section main member 1. The rangefinders 2 and cameras 6 are fixed to the upper tower section main member 1 by magnets on their sides. The rangefinders 2 and cameras 6 are adjusted so that they all point towards the tower section auxiliary support platform 4 on the lower tower section main member 5. The rangefinders 2 and cameras 6 are then connected to a monitor 12. The monitor 12 has several display areas, each displaying the images captured by the corresponding camera 6 and the data collected by the rangefinders 2. By observing the images and data collected by the cameras 6 and rangefinders 2, the operator can assist in achieving precise docking of the tower sections. The position of the upper tower section main member 1 can be adjusted in real time to align it with the lower tower section main member 5. The lower tower section main member 5 is equipped with a tower section connector 3, which has several bolt holes. The upper tower section main member 1 has bolt holes corresponding to the bolt holes in the tower section connector 3. The operator connects the upper tower section main member 1 to the tower section connector 3 using bolts.

[0038] Example 2:

[0039] See Figure 2 A segmented tower assembly includes a pre-positioned tower segment 10 and a tower segment 4 to be lifted. Several rangefinders 2 and several cameras 6 are fixed to the tower segment 4, and both the rangefinders 2 and cameras 6 are connected to a display 12. An auxiliary support platform 4 is provided on the pre-positioned tower segment 10, and the rangefinders 2 and cameras 6 on the tower segment 4 are all pointed towards the auxiliary support platform 4. The tower segment 4 is lifted by a crane 11, which is connected to a lifting rope 13, which is fixed to the top of the tower segment 4. A release device 8 is provided on the lifting rope 13. The display 12 includes a first display area and a second display area. The first display area includes several display units, each display unit displaying the images captured by the corresponding camera 6 and the data collected by the rangefinders 2. The second display area displays the hook status of the release device 8.

[0040] Preferably, the rangefinder 2 is an infrared laser rangefinder.

[0041] After assembling the bottom tower section, if there are intermediate tower sections, assemble those sections. First, install the rangefinder 2, camera 6, and auxiliary support platform 4 for the intermediate tower section. Using the connecting bolt holes at the four upper corners of the upper tower section main member 1, install the auxiliary support platform 4, the lower tower section main member 5, and the tower section connectors. Then, install the rangefinder 2 and camera 6 using magnetic bases at a distance of 300mm from the lower end face on both sides of the main member.

[0042] After the above installation is completed, the lifting rope 13 is used to lift the intermediate tower section 9 via the crane's main hook 7. Then, the operator uses the crane 11 to lift the tower section 9 above the already positioned tower section 10. The camera 6 on the tower section 9 captures the image, and the operator can view the real-time video information on the monitor 12 in the cab. The integrated monitor's functional areas include... Figure 3 As shown, with the help of video information, the operator uses the crane to align the hoisted tower section 9 with the already positioned tower section 10. Then, the crane is lowered slowly, and during the descent, the distance measuring device 2 measures the distance between the crane and the upper surface of the auxiliary support platform 4 of the positioned tower section 10 in real time. The operator monitors the distances of different groups in real time through the display 12. When all distance values ​​are stable and unchanged, it indicates that the hoisted tower section 9 is properly aligned. At this point, the unhooking device 8 begins the hook-opening action. After the hook-opening action is completed, the hook triggers the mechanical limit switch to release the signal, and the hook status on the display 12 shows "hook open". The operator then operates the crane to remove the boom, completing the erection of the first intermediate tower section. If there is more than one intermediate tower section, the above process is followed to complete the erection of all intermediate tower sections.

[0043] Finally, the construction workers climbed the tower and completed the bolt connection of each tower section from bottom to top, disassembled the auxiliary support platform 4, rangefinder 2 and camera 6 of the tower section, and retrieved the lifting ropes at the top of each tower section to complete the tower erection construction.

[0044] This invention acquires video information of the tower segment docking position via camera 6. The crane operator can monitor the docking position in real time via display 12 from the cab to understand the relative position of the tower segment 9 to be lifted and the already positioned tower segment 10, eliminating the need for an observer. By installing auxiliary support platforms 4 at the upper ends of the four corner main members of the already positioned tower segment 10 and rangefinders 2 at the lower ends of the four corner main members of the tower segment to be lifted, automatic aerial docking and accurate measurement and feedback of the positioning position of the tower segment to be lifted are achieved. The unhooking device 8 automatically disconnects the crane's main hook 7 from the tower segment to be lifted and provides feedback on the hook's open and closed status. Therefore, it effectively avoids the need for construction personnel to repeatedly climb up and down the tower and manually disconnect the crane's main hook 7, significantly reducing the intensity of high-altitude work for construction personnel, improving the efficiency of tower erection construction, and enhancing the level of intelligence in tower erection construction.
