Description

Technical Field

[0001] This utility model relates to the field of earthquake-resistant foundation structure technology, specifically an earthquake-resistant foundation structure for high-voltage transmission towers. Background Technology

[0002] High-voltage transmission towers are tower-like structures used to support and secure high-voltage transmission lines. They are typically made of steel and possess high mechanical strength and stability. Their primary function is to ensure the efficient and safe transmission of electrical energy to its destinations. Due to their considerable height, existing high-voltage transmission towers typically improve stability by increasing the volume of their foundation. However, this method requires more materials and time. To simplify construction and provide better seismic stability support for high-voltage transmission towers, a seismic-resistant foundation structure for high-voltage transmission towers is proposed.

[0003] For example, the earthquake-resistant foundation structure for a high-voltage transmission tower disclosed in the authorization announcement number CN221442255U includes an earthquake-resistant mechanism, a base mechanism is provided on the surface of the earthquake-resistant mechanism, a transmission tower mechanism is provided on the surface of the earthquake-resistant mechanism, the earthquake-resistant mechanism is located above the base mechanism, the transmission tower mechanism is located above the earthquake-resistant mechanism, and the earthquake-resistant mechanism includes a fixed outer shell.

[0004] Although it achieves the sliding connection of the main hydraulic rod and the auxiliary hydraulic rod inside the hydraulic base, which can buffer the longitudinal force of the device, the hydraulic base is snapped with the fixed shell, and the inner wall of the fixed shell is equipped with a buffer pad, which can absorb and consume the lateral force and vibration to a certain extent, and also reduce the wear between the devices. The setting of the limit groove and the locking block restricts the range of motion of the device, thereby reducing the vibration amplitude of the transmission tower and improving the seismic resistance and stability of the device.

[0005] However, this does not solve the problem that existing seismic-resistant foundation structures are not conducive to flexible adjustment and adaptation to construction pits of different widths during use, nor to the offsetting and buffering of vibrations in different directions, thus affecting the seismic resistance effect. Utility Model Content

[0006] The purpose of this utility model is to provide a seismic-resistant foundation structure for high-voltage transmission towers, in order to solve the problem mentioned in the background art that the seismic-resistant foundation structure is not convenient to flexibly adjust and adapt to construction pits of different widths, is not conducive to offsetting and buffering vibrations in different directions, and affects the seismic resistance effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant foundation structure for a high-voltage transmission tower, comprising a foundation pit frame and a fixing layer. The fixing layer is disposed inside the foundation pit frame, and a mounting base is disposed above the fixing layer. Multiple sets of connecting seats are disposed at equal intervals on the outer wall of the mounting base. A sleeve is movably installed inside each connecting seat, and a sliding rod is slidably installed inside each sleeve. A locking pin is disposed on the side wall of each sleeve, extending through the sleeve to the surface of the sliding rod, and the locking pin is threadedly connected to the sleeve. Each sleeve has a support arm inside the connecting seat on one side. Each support arm has a hinge shaft at the end near the connecting seat, and the support arm is movably connected to the connecting seat through the hinge shaft. Each slide rod has a pin at the end near the support arm, and the slide rod is movably connected to the support arm through the pin. Each support arm has a connecting arm at the end away from the connecting seat. Each connecting arm has a connecting bolt at the top, and the connecting arm is movably connected to the support arm through the connecting bolt. Each connecting arm has a screw symmetrically arranged at the bottom end, and the screw can extend into the interior of the fixed layer.

[0008] Preferably, the top of the foundation pit frame is provided with multiple sets of L-shaped frames at equal intervals, and the L-shaped frames are fixedly connected to the foundation pit frame.

[0009] Preferably, hydraulic cylinders are provided on the side walls of the L-shaped frame, and the hydraulic cylinders are fixedly connected to the L-shaped frame.

[0010] Preferably, each of the hydraulic cylinders is provided with a push arm at its output end, and an arc-shaped block is provided at the end of the push arm away from the hydraulic cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the earthquake-resistant foundation structure not only realizes flexible adjustment to adapt to construction pits of different widths, which facilitates the offsetting and buffering of vibrations in different directions, but also improves the earthquake resistance effect.

[0012] When installing high-voltage transmission towers, a foundation pit frame of the corresponding size is excavated, placed inside the pit, and concrete is poured into the frame to form a fixing layer. The angle of the support arm is then adjusted according to the different pit widths. The adjustment method is as follows: Loosen the locking pin to separate the sliding rod from the sleeve. Move the sliding rod, allowing it to slide inside the sleeve. The sliding rod, via a pin, drives the support arm to rotate around the hinge axis. The support arm then drives the connecting arm and screw to rotate, adjusting the angle of the support arm so that multiple sets of support arms can adapt to pits of different widths. Then, tighten the locking pin to connect the sliding rod to the sleeve, maintaining the support arm in its current position. Next, rotate the connecting arm, which rotates around the connecting bolt. The connecting arm drives the screw to rotate, making the screw perpendicular to the fixing layer. Finally, tighten the connecting bolt to fix the connecting arm to the support arm. Drill holes at the corresponding positions on the fixing layer and... Insert expansion bolts and drive the screws into the expansion bolts to fix the support arm to the fixed layer. Multiple sets of support arms provide support to the mounting base through connecting seats. Insert the connecting feet of the high-voltage transmission tower into the mounting base, then open the hydraulic cylinder. The hydraulic cylinder drives the push arm to move, which in turn drives the arc blocks to move, so that multiple sets of arc blocks contact the feet and clamp and fix them. Since the vibration is divided into lateral vibration and longitudinal vibration, when subjected to lateral vibration, the feet can disperse the lateral vibration to multiple sets of arc blocks and cancel it out. When subjected to vertical vibration, the feet can disperse the vibration to multiple sets of support arms and cancel it out, thereby providing more stable seismic support for the high-voltage transmission tower. This allows for flexible adjustment and adaptation to construction pits of different widths, facilitates the cancellation and buffering of vibrations in different directions, provides stable support for the high-voltage transmission tower, and improves the seismic resistance.

Each connecting arm 10 is provided with a screw 11 symmetrically at the bottom end. The screw 11 can extend into the interior of the fixing layer 6.

[0021] The top of the foundation pit frame 1 is provided with multiple sets of L-shaped frames 2 at equal intervals, and the L-shaped frames 2 are fixedly connected to the foundation pit frame 1.

[0022] Hydraulic cylinders 3 are installed on the side walls of L-shaped frame 2. The hydraulic cylinders 3 serve as power drives and are fixedly connected to L-shaped frame 2.

[0023] Each hydraulic cylinder 3 is equipped with a push arm 4 at its output end, and an arc-shaped block 5 is provided at the end of the push arm 4 away from the hydraulic cylinder 3.

[0024] When installing a high-voltage transmission tower, firstly, excavate the corresponding sized foundation pit frame 1, place the foundation pit frame 1 inside the foundation pit, and inject concrete into the foundation pit frame 1 to form a fixing layer 6. Then, adjust the angle of the support arm 9 according to the different foundation pit widths. The adjustment method is as follows: loosen the locking pin 14 to separate the sliding rod 15 from the sleeve 13, move the sliding rod 15, and the sliding rod 15 slides inside the sleeve 13. The sliding rod 15 drives the support arm 9 to rotate around the hinge shaft 12 through the pin 16. The support arm 9 drives the connecting arm 10 and the screw 11 to rotate, thereby adjusting the angle of the support arm 9 so that multiple sets of support arms 9 can adapt to foundation pits of different widths. Then, the locking pin 14 is tightened to connect the slide rod 15 to the sleeve 13, keeping the support arm 9 in its current state. After that, the connecting arm 10 is rotated, and the connecting arm 10 rotates around the connecting bolt 17. The connecting arm 10 drives the screw 11 to rotate and make the screw 11 perpendicular to the fixed layer 6. Finally, the connecting bolt 17 is tightened to connect the connecting arm 10 to the support. The support arm 9 is fixedly connected. Holes are drilled at corresponding positions on the fixed layer 6 and expansion bolts are inserted. The screw 11 is driven into the expansion bolts to fix the support arm 9 to the fixed layer 6. Multiple sets of support arms 9 provide support to the mounting base 7 through the connecting seat 8. The connecting foot of the high-voltage transmission tower is inserted into the mounting base 7. Then, the hydraulic cylinder 3 is opened, which drives the push arm 4 to move. The push arm 4 drives the arc block 5 to move, so that multiple sets of arc blocks 5 contact the foot and clamp and fix it. Since the vibration is divided into lateral vibration and longitudinal vibration, when subjected to lateral vibration, the lateral vibration can be dispersed to multiple sets of arc blocks 5 through the foot and canceled out. When subjected to vertical vibration, the vibration can be dispersed to multiple sets of support arms 9 through the foot and canceled out. This provides more stable seismic support for the high-voltage transmission tower, realizes flexible adjustment to adapt to construction pits of different widths, facilitates the cancellation and buffering of vibrations in different directions, facilitates stable support for the high-voltage transmission tower, and improves the seismic effect.

[0025] Working principle: Concrete is injected into the foundation pit frame 1 to form a fixed layer 6. Then, the angle of the support arm 9 is adjusted according to different foundation pit widths. The adjustment method is as follows: Loosen the locking pin 14 to separate the slide rod 15 from the sleeve 13. Move the slide rod 15, which drives the support arm 9 to rotate around the hinge shaft 12 via the pin 16. The support arm 9 drives the connecting arm 10 and the screw 11 to rotate, thereby adjusting the angle of the support arm 9 so that multiple sets of support arms 9 can adapt to foundation pits of different widths. Then, lock the locking pin 14 to connect the slide rod 15 to the sleeve 13, keeping the support arm 9 in its current state. Then, rotate the connecting arm 10, which rotates around the connecting bolt 17. The connecting arm 10 drives the screw 11 to rotate and make the screw 11 perpendicular to the fixed layer 6. Finally, lock the connecting bolt 17 to make the connecting arm 10 rotate. The support arm 9 is fixedly connected to the support arm 9. Holes are drilled at the corresponding positions on the fixed layer 6 and expansion bolts are inserted. The screw 11 is driven into the expansion bolts to fix the support arm 9 to the fixed layer 6. Multiple sets of support arms 9 provide support to the mounting base 7 through the connecting seat 8. The connecting foot of the high-voltage transmission tower is inserted into the mounting base 7. Then, the hydraulic cylinder 3 is opened, and the hydraulic cylinder 3 drives the push arm 4 to move. The push arm 4 drives the arc block 5 to move, so that multiple sets of arc blocks 5 contact the foot and clamp and fix it. Since the vibration is divided into lateral vibration and longitudinal vibration, when subjected to lateral vibration, the lateral vibration can be dispersed to multiple sets of arc blocks 5 and canceled out by the foot. When subjected to vertical vibration, the vibration can be dispersed to multiple sets of support arms 9 and canceled out by the foot, thereby providing more stable seismic support for the high-voltage transmission tower.
