Description

Technical Field

[0001] This utility model relates to the field of power transmission line crossing construction technology, and in particular to a temporary protective support for power transmission line crossing construction. Background Technology

[0002] Crossing highways, railways, rivers, or other facilities is a common construction scenario during power transmission line construction. Traditional crossing frames are mostly constructed using steel pipes or bamboo, which, while low-cost and using readily available materials, have several significant drawbacks: 1. Long construction period: The traditional scaffolding erection usually takes 3-5 days, which seriously affects the progress of the project, especially during emergency repairs or construction, where the problem of low efficiency is particularly prominent. 2. Road closures required: To ensure construction safety, it is usually necessary to close roads that cross the area, causing traffic disruptions and affecting public travel and transportation efficiency; 3. Poor terrain adaptability: Traditional structures have limited adaptability to changes in terrain. When encountering large elevation differences, steep slopes, or water obstacles, the difficulty of construction increases dramatically, and it may even be impossible to carry out the project. To address this issue, we propose a temporary protective support system for power transmission line crossing construction. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a temporary protective support for power transmission line crossing construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A temporary protective support for power transmission line crossing construction includes multiple support columns that are threaded together. The lower end of the bottom support column is fixed with a reinforcement mechanism, and the upper end of the top support column is fixed with a fixing plate. A hydraulic telescopic mechanism is installed on the fixing plate, and a moving mechanism is connected to the upper end of the hydraulic telescopic mechanism. An extension structure is connected to the moving mechanism, and a support plate is detachably installed on the upper end of the extension structure. Fixing platforms are fixed on both sides of the upper end of the support plate, and multiple slots are evenly spaced on the fixing platforms.

[0005] Preferably, the reinforcement mechanism includes a base plate fixed to the lower end of one of the support columns, and ground nails are fixed to both sides of the lower end of the base plate.

[0006] Preferably, the hydraulic telescopic mechanism includes a hydraulic cylinder fixed to one side of the upper end of the fixed plate, with a movable ring sleeved on one of the support columns, and the piston rod end of the hydraulic cylinder fixed to the lower end of the movable ring.

[0007] Preferably, the moving mechanism includes four connecting rods rotatably connected to the moving ring.

[0008] Preferably, the extended structure includes a mounting block fixed to the upper end of one of the support columns, and four support rods are rotatably connected at equal intervals around the circumference of the mounting block, with one end of a connecting rod on the same side rotatably connected to the lower end of a support rod on the same side.

[0009] Preferably, four insert rods and one limiting rod are fixed at equal intervals at the lower end of the support plate, a limiting hole is provided at the upper end of the mounting block, an insertion hole is provided on one side of the upper end of the support rod, one insert rod on the same side is inserted into one insertion hole on the same side, and the limiting rod is inserted into the limiting hole.

[0010] In this utility model, during use: 1. Ground preparation and support column assembly According to the terrain and elevation of the site, the engineers connected multiple support columns with threads and adjusted them to the required height. The bottom was fixed with a base plate and ground nails to ensure the stability of the foundation. 2. Hydraulic system start-up and deployment The hydraulic cylinder is activated, pushing the moving ring upwards. The moving ring causes the four connecting rods to unfold outwards, which in turn pushes the support rods open, forming an umbrella-shaped frame structure; 3. Installation and locking of the support plate The support plate is hoisted to the top and locked by inserting the rod into the hole. The limit rod is inserted into the limit hole to ensure that the platform is stable and does not shake. 4. Erection of power transmission lines The power transmission lines are fixed to the mounting platforms on both sides of the support plate via slots, achieving safe and stable installation. 5. Recycling and Storage The hydraulic cylinder reverses its movement, retracting the moving ring and causing the entire frame to retract. After the support plate is removed, the overall structural volume is reduced by 70%, making it easier to transport and use next time.

[0011] This utility model has the following advantages: 1. Driven by a hydraulic system, it can be deployed or retracted within 30 minutes, which is more than 80% more efficient than traditional cross-pass frames. It does not require road closures and can achieve "construction while maintaining traffic flow", greatly reducing the disruption to traffic caused by construction. 2. The support columns adopt modular threaded connections, which can be flexibly adjusted according to the site terrain, making them suitable for various complex terrains such as mountains, hills, and rivers, thus improving construction adaptability; 3. Each component is detachable and replaceable, with a high degree of standardization, making it easy to maintain and reuse. It has a small volume when stored, resulting in low transportation costs and making it suitable for use in multiple locations. 4. Compared with traditional bamboo / steel pipe crossing frames, this device has low material consumption, reduces timber felling and metal waste, and automated operation reduces reliance on manpower and lowers construction difficulty; In summary, this utility model can flexibly adjust its height according to the site terrain, making it suitable for various complex terrains such as mountains, hills, and rivers, thus improving construction adaptability. All components are detachable and replaceable, with a high degree of standardization, facilitating maintenance and reuse. It has a small volume after storage, resulting in low transportation costs and suitability for use in multiple locations. Compared with traditional crossing frames, it improves efficiency by more than 80%, eliminates the need for road closures, and automates operation to reduce reliance on manpower and lower construction difficulty.

The reinforcement mechanism includes a base plate 6 fixed to the lower end of one of the support columns 5. Both sides of the lower end of the base plate 6 are fixed with ground nails 7.

The hydraulic cylinder 8 adopts a high-precision servo hydraulic system with pressure feedback and displacement control functions, which can realize intelligent adjustment of the unfolding speed and angle. The moving mechanism includes four connecting rods 3 rotatably connected to the moving ring 9. The moving ring 9 is linked with the support rod 2 through the four connecting rods 3 to form an "umbrella-like" unfolding mechanism. The rotating shaft of the support rod 2 adopts a self-lubricating spherical bearing to reduce wear, extend service life, and has good symmetry and force balance to ensure a smooth unfolding process. The extended structure includes a mounting block 16 fixed to the upper end of one of the support columns 5. Four support rods 2 are rotatably connected to the circumference of the mounting block 16 at equal intervals. One end of a connecting rod 3 on the same side is rotatably connected to the lower end of a support rod 2 on the same side. The hydraulic cylinder 8 operates automatically under the control of PLC, and the position of the moving ring 9 is fed back in real time by the displacement sensor to ensure that the unfolding angle and speed are consistent. The unfolding process can be completed within 30 minutes, which is far more efficient than the traditional manual assembly method.

The bottom was fixed to the ground nails 7 with the base plate 6 to ensure the foundation was stable. 2. Hydraulic system start-up and deployment Hydraulic cylinder 8 is activated, pushing the moving ring 9 upward.

After the support plate is removed, the overall structural volume is reduced by 70%, making it easier to transport and use next time.

[0016] The entire device adopts an umbrella-shaped folding frame system, which forms a stable support platform when unfolded and reduces the volume by 70% when folded. It can automatically unfold / fold within 30 minutes, while the traditional method takes 4 hours, greatly improving efficiency and speed.
