Description

Technical Field

[0001] This invention relates to the field of cross-river tower construction technology, and in particular to a multifunctional platform for cross-river tower construction in rivers. Background Technology

[0002] In long-span power transmission line projects (such as crossing navigable rivers), the crossing towers are typically located in deep water areas in the middle of the river, characterized by long construction periods and complex hydrological and meteorological conditions. Currently, the construction of crossing towers in rivers mainly relies on the construction of temporary floating platforms. Long-span towers have extremely high requirements for verticality and axial deviation (at the millimeter level), thus necessitating the installation of monitoring instruments to measure the construction process. However, the measuring instruments installed on the construction platform are susceptible to interference from construction vibrations, causing fluctuations in measurement data and affecting the accuracy of tower erection.

[0003] Therefore, there is an urgent need for a multi-functional platform for the construction of cross-river towers to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional platform for the construction of a cross-river tower, which can ensure the stability and accuracy of the measurement data of the measuring instruments, thereby ensuring the accuracy of the tower body assembly.

[0005] To achieve this objective, the present invention adopts the following technical solution: A multi-functional platform for the construction of a cross-river tower includes a cross-river tower construction platform, an auxiliary platform, and an inclined ladder. The auxiliary platform includes a measuring platform, which is spaced apart from the cross-river tower construction platform. The measuring platform includes a first frame, a vibration damping support, and an instrument mounting platform. The vibration damping support is disposed on the first frame, and the instrument mounting platform is disposed on the vibration damping support. The instrument mounting platform is used to mount measuring instruments. One end of the inclined ladder is connected to the measuring platform, and the other end extends toward the construction platform of the crossing tower. A gap is provided between the end of the inclined ladder that is close to the construction platform of the crossing tower and the construction platform of the crossing tower.

The support frame is fixedly connected to the third frame, and the pull wire lug is connected to the support frame.

[0009] As an improvement to the above technical solution, the support frame includes a first longitudinal beam, a second longitudinal beam, and a crossbeam. The first longitudinal beam and the second longitudinal beam are spaced apart in the horizontal direction. One end of the crossbeam is fixedly connected to the middle of the first longitudinal beam in the length direction, and the other end is fixedly connected to the middle of the second longitudinal beam in the length direction.

The dock assembly includes a second straight ladder, the top of which is connected to the instrument installation platform, and the bottom of which extends towards the river surface.

[0014] As an improvement to the above technical solution, the wharf assembly also includes multiple buffer pads, and the buffer pads are fixedly installed on the side of the first frame, the third frame and the fourth frame away from the construction platform of the crossing tower.

[0022] like Figures 1-3 As shown, this embodiment provides a multi-functional platform for the construction of a cross-river tower, including a cross-river tower construction platform 1, an auxiliary platform 2, and an inclined ladder 3. The auxiliary platform 2 includes a measuring platform 21, which is spaced apart from the cross-river tower construction platform 1. The measuring platform 21 includes a first frame 211, a vibration damping support 212, and an instrument mounting platform 213. The vibration damping support 212 is mounted on the first frame 211, and the instrument mounting platform 213 is mounted on the vibration damping support 212. The instrument mounting platform 213 is used to mount measuring instruments. One end of the inclined ladder 3 is connected to the measuring platform 21, and the other end extends towards the cross-river tower construction platform 1. A gap is provided between the end of the inclined ladder 3 near the cross-river tower construction platform 1 and the cross-river tower construction platform 1.

[0023] The multi-functional platform provided in this embodiment for the construction of a cross-river tower includes an independent measuring platform 21 for installing measuring instruments. The measuring platform 21 and the cross-river tower construction platform 1 are connected by an inclined ladder 3, with a gap between the inclined ladder 3 and the cross-river tower construction platform 1 to avoid the adverse effects of construction vibrations on the measuring instrument data. In addition, a vibration damping support 212 is provided between the instrument mounting platform 213 and the first frame 211 of the measuring platform 21 to reduce the adverse effects of vibrations caused by water flow impacts on the first frame 211 on the measuring instrument data, ensuring stable and accurate measuring data, thereby ensuring the accuracy of the cross-river tower assembly.

[0024] In this embodiment, the first frame 211 includes multiple steel pipe piles spaced apart. The bottom ends of the steel pipe piles are all inserted below the riverbed surface 100. Adjacent steel pipe piles are connected by connecting rods. The top of the steel pipe piles is supported by No. 20 channel steel as a main beam. No. 18 channel steel is laid on top of the main beam as a secondary beam. The main beam and the secondary beam are welded together to increase stability.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the multi-functional platform for the construction of a river crossing tower provided in this embodiment also includes a second frame 4. The second frame 4 is located at the end of the inclined ladder 3 near the construction platform 1 of the crossing tower. The inclined ladder 3 is fixedly connected to the second frame 4, which supports the end of the inclined ladder 3 near the construction platform 1 of the crossing tower, ensuring the safety of the inclined ladder 3 when the end of the inclined ladder 3 near the construction platform 1 of the crossing tower is not connected to the construction platform 1 of the crossing tower. In this embodiment, the second frame 4 includes multiple spaced steel pipe piles, the bottom ends of which are inserted below the riverbed surface 100. Adjacent steel pipe piles are connected by connecting rods, and the inclined ladder 3 is fixedly connected to the steel pipe piles of the second frame 4.

[0026] Furthermore, the vibration damping support 212 includes a vibration isolation pad and a damper. The vibration isolation pad is disposed on the first frame 211, the damper is disposed on the vibration isolation pad, and the instrument mounting platform 213 is disposed on the damper. The damper and the vibration isolation pad work together to reduce the vibration of the instrument mounting platform 213. In this embodiment, the vibration isolation pad is a rubber vibration isolation pad. Both the damper and the rubber vibration isolation pad are existing devices in the art, and their further structure and principle will not be described here.

[0027] In this embodiment, multiple vibration damping supports 212 are provided, and the multiple vibration damping supports 212 are spaced apart and jointly support the instrument mounting platform 213.

[0028] Optionally, Figures 1-3As shown, the auxiliary platform 2 also includes an anchor platform 22, which comprises a third frame 221, a support frame 222, and a guy wire lug 223. The support frame 222 is fixedly connected to the third frame 221, and the guy wire lug 223 is connected to the support frame 222. For cross-towers, the tower erection typically employs the internal or external guy wire gantry method. The gantry requires significant lifting force and a stable rear anchor point during the lifting process. Existing general-purpose construction platforms do not have dedicated anchor point structures for lifting poles. During construction, it is often necessary to temporarily weld reinforcing ribs or use the tower material itself as a stress point. This not only carries high operational risks and can easily cause local instability or deformation of the tower material, but also lacks standardized stress calculation basis, resulting in significant safety hazards. In this embodiment, a dedicated anchor point platform 22 is set up, with a guy wire lug 223 with strip-shaped holes as a stress point. The guy wire lug 223 is firmly connected to the third frame 221 through a support frame 222. The guy wire lug 223 and the support frame 222 are designed and installed according to stress calculation data to ensure construction safety.

[0029] Furthermore, Figure 3 As shown, the support frame 222 includes a first longitudinal beam 2221, a second longitudinal beam 2222, and a crossbeam 2223. The first longitudinal beam 2221 and the second longitudinal beam 2222 are spaced apart in the horizontal direction. One end of the crossbeam 2223 is fixedly connected to the middle of the first longitudinal beam 2221 along its length, and the other end is fixedly connected to the middle of the second longitudinal beam 2222 along its length. A guy wire lug 223 is fixedly connected to the middle of the crossbeam 2223 along its length. Both ends of the first longitudinal beam 2221 and both ends of the second longitudinal beam 2222 along its length are fixedly connected to the third frame 221 by pre-embedded anchor bolts. In this embodiment, the third frame 221 includes multiple spaced steel pipe piles. The bottom ends of the steel pipe piles are all inserted below the riverbed surface 100, and adjacent steel pipe piles are connected by connecting rods. The pre-embedded anchor bolts are composed of multiple Q235 steel plates, which are welded to the inner wall of the steel pipe pile. The upper ends extend out of the steel pipe pile and are locked to the first longitudinal beam 2221 and the second longitudinal beam 2222 through special fasteners. The guy wire lug 223 is welded to the top of the crossbeam 2223.

[0030] Optionally, Figures 1-3As shown, the auxiliary platform 2 also includes a lookout platform 23, which is located on one side of the crossing tower construction platform 1 and spaced apart from it. The lookout platform 23 includes a fourth frame 231 and a walking platform 232 mounted on top of the fourth frame 231. The construction area in the river is busy and requires 24-hour navigation monitoring. When severe weather occurs or the monitoring vessel is withdrawn for any reason, existing construction platforms often lack built-in lookout functions and emergency shelter space, making it difficult to respond quickly in case of emergencies. Therefore, this embodiment sets up a lookout platform 23, with the walking platform 232 positioned at the highest point of the auxiliary platform 2 as a fixed waterborne lookout post. The walking platform 232 is equipped with an audible and visual alarm device and an emergency supplies storage cabinet. In this embodiment, the fourth frame 231 includes multiple steel pipe piles spaced apart. The bottom ends of the steel pipe piles are all inserted below the riverbed surface 100. Adjacent steel pipe piles are connected by connecting rods. The top of the steel pipe piles is supported by No. 20 channel steel as a main beam. No. 18 channel steel is laid on top of the main beam as a secondary beam. The main beam and the secondary beam are welded together to increase stability.

[0031] Furthermore, Figure 1 and Figure 2 As shown, the auxiliary platform 2 also includes a first vertical ladder 24, which connects the walking platform 232 and the instrument installation platform 213, and serves as an emergency evacuation passage.

[0032] Furthermore, Figure 1 and Figure 3 As shown, the lookout platform 23, the measurement platform 21, and the anchor point platform 22 are all located on the same side of the cross-tower construction platform 1 to facilitate passage and coordination between the platforms.

[0033] Optionally, Figure 1 As shown, the auxiliary platform 2 also includes a dock component 25, which is located on the side of the auxiliary platform 2 away from the construction platform 1 of the crossing tower. The dock component 25 includes a second straight ladder 251, the top of which is connected to the instrument installation platform 213, and the bottom of which extends towards the river surface. Existing construction platforms often require separate floating boats or auxiliary facilities for measurement control and personnel and material transfer during foundation construction. This leads to frequent disassembly and assembly, increasing project costs and extending the construction period. In this embodiment, the dock component 25 is set on the side of the auxiliary platform 2 away from the construction platform 1 of the crossing tower as a temporary dock, eliminating the need for frequent disassembly and assembly and facilitating the transfer of personnel and materials. The second straight ladder 251 serves as a passage between the temporary dock and the instrument installation platform 213.

[0034] Furthermore, Figure 1As shown, the dock assembly 25 also includes multiple buffer pads 252. Buffer pads 252 are fixedly installed on the side of the first frame 211, the third frame 221, and the fourth frame 231 away from the construction platform 1 of the crossing tower. The buffer pads 252 are located on the outside of the steel pipe piles of each frame. When a ship berths, the buffer pads 252 can buffer the impact force between the ship and each frame, reducing damage to the ship and each frame during the berthing process. In addition, the dock assembly 25 also includes lifting ropes to facilitate the hoisting of cargo.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
