Description

Technical Field

[0001] This invention belongs to the field of overhead transmission line foundation construction technology, specifically relating to a foundation pouring device for transmission line construction. Background Technology

[0002] Overhead transmission lines mainly refer to exposed overhead lines, erected above the ground. They are transmission lines that use insulators to fix the transmission conductors to towers standing upright on the ground to transmit electrical energy. They are relatively easy to erect and maintain, and have lower costs. However, they are susceptible to weather and environmental factors (such as strong winds, lightning strikes, pollution, and snow), which can cause faults. Furthermore, the entire transmission corridor occupies a large area of ​​land and can easily cause electromagnetic interference to the surrounding environment. The foundation structure of overhead transmission lines is constructed using a casting device, which consists of a storage tank and a casting mechanism.

[0003] Currently, existing foundation pouring equipment for power transmission line construction experiences vibrations during operation due to uneven ground. These vibrations cause the equipment to move on the ground, preventing proper pouring. Furthermore, existing pouring equipment relies mainly on manual adjustment of the pouring position. When the pouring pipe is too high above the bottom of the pit, the air content in the foundation increases, thus reducing the foundation's quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a foundation pouring device for power transmission line construction.

[0005] The technical problem solved by this invention is achieved through the following technical solution: A foundation pouring device for power transmission line construction includes a tank, a mounting frame, support legs, and pulleys. The support legs are fixedly installed at the four corners of the mounting frame, and the pulleys are installed at the bottom of the support legs. The tank is mounted on the mounting frame, and a pouring pipe is slidably connected to the bottom of the tank. A transmission pipe is fixedly installed at the bottom of the mounting frame, and a transmission mechanism fixedly installed on the surface of the transmission pipe and fixedly installed with the pouring pipe. A first motor is fixedly installed at one end of the transmission mechanism. Four fixing rods are fixedly installed at the bottom of the mounting frame, and the bottoms of the four fixing rods are connected to a fixing frame. An installation plate communicating with the bottom of the pouring pipe is fixedly installed at the bottom of the pouring pipe, and an installation plate is fixedly installed inside the installation plate. A float switch connected to the first motor is fixedly installed at the bottom of the installation plate. The tank body is rotatably connected to a feeding screw rod, the top of which extends to the top of the tank body and is fixedly installed with a second motor. The top of the tank body is fixedly installed with a feeding hole. The bottom of the mounting bracket is fixedly mounted with a fixing tube that is slidably connected to the surface of the fixing rod. The upper end of the surface of the fixing tube is threaded with a fastening screw, and the fastening screw is threadedly connected to the upper part of the fixing tube.

[0006] Furthermore, the mounting bracket moves to the top of the casting module by sliding pulleys on the ground via support legs. Then, the first motor is started, which drives the transmission mechanism to rotate. The transmission mechanism drives the casting pipe to move inside the transmission pipe, so that the casting pipe moves into the casting module, and the mounting plate moves to the bottom of the casting module. The second motor is then started, which drives the feeding screw to rotate. The feeding screw drives the casting liquid inside the tank to rotate, so that the casting liquid moves into the casting pipe. When the bottom of the casting pipe is being poured or the casting liquid is close to the bottom, the float switch triggers the first motor, thereby moving the casting pipe to achieve automatic casting in the casting module.

[0007] The advantages and beneficial effects of this invention are as follows: 1. The present invention has a fixed rod and a fixed frame. The fixed rod drives the fixed frame to extend into the interior of the casting module, so that the mounting frame and the casting module are fixed, thereby preventing the mounting frame from shaking during the casting process and preventing the mounting frame from shifting on the ground, thus helping to ensure the normal casting of the device.

[0008] 2. This invention is equipped with an installation plate, a mounting plate, and a float switch. Utilizing the principle that the float switch floats when it comes into contact with liquid, the float switch triggers the first motor when the bottom of the pouring pipe is being poured or when the pouring liquid approaches, thereby driving the pouring pipe to move. This achieves automated control of the pouring position of the pouring equipment, thus replacing the manual operation process and helping to reduce the workload of workers.

[0009] 3. This invention has been applied in five projects, including the Xinjiang Tieganlik-Ruoqiang 750 kV transmission line project, the Jinshang-Hubei ±800 kV UHVDC transmission line project, the Gansu-Zhejiang ±800 kV UHVDC transmission line project, and the Datong-Tianjin South 1000 kV UHVAC transmission line project. The average time for adjusting the pouring position and vibration during the excavation foundation pouring process was reduced by 21.3%. Attached Figure Description

[0012] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.

[0013] This invention relates to a foundation pouring device for power transmission line construction. Its innovation lies in the following: it includes a tank 1, with a mounting frame 2 fixedly installed at the bottom of the tank 1. A pouring pipe 3 is slidably connected to the lower part of the tank 1. A transmission pipe 4 is fixedly installed at the bottom of the mounting frame 2. A transmission mechanism, fixedly installed with the pouring pipe 3, is fixedly installed on the surface of the transmission pipe 4. A first motor 5 is fixedly installed at one end of the transmission mechanism. Four fixing rods 6 are fixedly installed at the bottom of the mounting frame 2. A fixing frame 7 is fixedly installed at the bottom of the four fixing rods 6. A mounting plate 8, communicating with the bottom of the pouring pipe 3, is fixedly installed at the bottom of the mounting plate 8. A mounting plate 9 is fixedly installed inside the mounting plate 8. A float switch 10, electrically connected to the first motor 5, is fixedly installed at the bottom of the mounting plate 9. By setting the fixing rods 6 and the fixing frame 7, the fixing rods 6 drive the fixing frame 7 to extend to the pouring pipe 3. The internal structure of the pouring module secures the mounting frame 2 and the pouring module, preventing the mounting frame 2 from shaking during pouring and thus preventing displacement on the ground, ensuring normal pouring operation. The system includes a pouring pipe 3, a transmission pipe 4, a transmission mechanism, and a first motor 5. The first motor 5 drives the transmission mechanism to rotate, which in turn moves the transmission pipe 4 within the pouring pipe 3, changing the height of the pouring pipe 3 within the pouring module. The system also includes a mounting plate 8, a mounting plate 9, and a float switch 10. Utilizing the principle that the float switch 10 floats when it comes into contact with liquid, the float switch 10 triggers the first motor 5 when the bottom of the pouring pipe 3 is being poured or when the liquid approaches, thus moving the pouring pipe 3. This achieves automated control of the pouring position, replacing manual operation and reducing the workload of workers.

[0014] Regarding the structure of tank 1, a feeding screw 11 is rotatably connected inside tank 1. The top of the feeding screw 11 extends to the top of tank 1 and a second motor 12 is fixedly installed thereon. A feeding hole 13 is fixedly installed on the top of tank 1. By setting up the feeding screw 11, the second motor 12 and the feeding hole 13, the second motor 12 drives the feeding screw 11 to rotate, thereby driving the pouring liquid inside tank 1 to rotate and discharge it into the pouring pipe 3 through the feeding hole 13.

[0015] For the structure of mounting bracket 2, a fixing tube 14 is fixedly installed at the bottom of mounting bracket 2 and slidably connected to the surface of fixing rod 6. A fastening screw 15 is threadedly connected to the upper end of the surface of fixing tube 14. The fastening screw 15 is threadedly connected to the upper part of fixing rod 6. By setting fixing tube 14 and fastening screw 15, fixing rod 6 slides in fixing tube 14, driving fixing bracket 7 to move, thereby changing the height of fixing bracket 7. The fastening screw 15 is threadedly connected to fixing rod 6, thereby fixing fixing bracket 7 to fixing tube 14.

[0016] For the structure of mounting frame 2, support legs 16 are fixedly installed at the four corners of the bottom of mounting frame 2. By setting support legs 16, the bottom of mounting frame 2 is higher than the ground, which makes it easier for the equipment to be placed at the bottom of mounting frame 2.

[0017] For the structure of the support legs 16, pulleys 17 are fixedly installed at the bottom of each of the four support legs 16. By setting the pulleys 17, the support legs 16 can slide on the ground.

[0018] The specific implementation process of this invention is as follows: First, the mounting frame 2 is pushed, and the mounting frame 2 slides on the ground via the support leg 16 and pulley 17, so that the mounting frame 2 moves above the casting module. Then, the first motor 5 is started, and the first motor 5 drives the transmission mechanism to rotate. The transmission mechanism drives the casting pipe 3 to move inside the transmission pipe 4, so that the casting pipe 3 moves into the casting module, and the mounting plate 8 moves to the bottom above the casting module. Then, the second motor 12 is started, and the second motor 12 drives the feeding screw 11 to rotate. The feeding screw 11 drives the casting liquid inside the tank 1 to rotate, so that the casting liquid moves into the casting pipe 3 and enters the casting pipe 3. When the bottom of the casting pipe 3 is being poured or the casting liquid is close, the float switch 10 will trigger the first motor 5, thereby driving the casting pipe 3 to move, realizing automatic casting in the casting module.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
