Technical Field
[0001] The present invention relates to the technical field of electric tower installation, and particularly to an installation component for a transmission tower. Background Art
[0002] A cylindrical high-voltage wire tower is a support structure for power transmission, usually made of materials such as steel or concrete. Its shape is similar to a cylinder and is usually composed of one or more cylinders. Cylindrical high-voltage wire towers are usually used to transmit high-voltage electricity because they can withstand the impact of high voltage and large current.
[0003] Among them, the tower pole of a metal high-voltage wire tower is usually prefabricated in a factory and then transported to the installation site by means of transportation tools (such as trucks, shipping, etc.). At the site, the assembly work of the tower pole needs to be carried out, and large lifting equipment is required for hoisting.
[0004] In the prior art, the tower pole of a metal high-voltage wire tower is composed of multiple prefabricated tower poles. During assembly, after the foundation piles are installed at the designated location, the tower pole at the bottom is installed by the cooperation of a crane and workers. Then, the second tower pole is hoisted by the crane, and the second tower pole is moved directly above the bottom tower pole. Then, the workers manually align the tower poles. However, since the workers are on the tower pole on the ground, the workers do not have a normal force application point and are working at high altitude. There is not only a risk of falling, but also because the force application points are few, it increases the difficulty of manually dragging the tower pole for alignment, reduces the installation efficiency, and the tower pole hoisted by the crane may also fall due to an accident, thus hitting the workers, resulting in injury or even death of the workers. In order to improve the installation efficiency and the safety of the workers, an installation component for a transmission tower is designed herein. Summary of the Invention
[0005] The present invention is proposed to solve the problem that the installation efficiency and the safety of workers need to be improved in the prior art, and provides an installation component for a transmission tower.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] For the convenience of quick alignment, further, the guiding plug includes a cylindrical platform fixedly connected to the second mounting head and a tapered platform integrally formed with the cylindrical platform. The tapered platform is inserted into the tapered groove, and the cylindrical platform is inserted into the cylindrical groove.
[0010] To further improve the alignment effect, furthermore, a triangular insertion plate is fixedly connected to the tapered platform. Above the triangular insertion plate, a limiting plate integrally formed with a rectangular cross-section is provided. A triangular insertion slot is provided in the cylindrical groove, and a limiting slot with a rectangular cross-section is provided above the triangular insertion slot. The triangular insertion plate is inserted into the triangular insertion slot, and the limiting plate is inserted into the limiting slot.
[0011] Preferably, a limiting hole is provided in the fixing bolt.
[0012] To fix the fixing bolt, preferably, a first mounting cavity is provided in the first mounting head. A first piston plate is slidably connected in the first mounting cavity. A fixing rod is fixedly connected to the first piston plate. The fixing rod extends out of the first mounting cavity and is inserted into the limiting hole. A fixing hole is provided in the first mounting head. After the fixing rod completely extends out, it extends into the fixing hole.
[0013] Preferably, a magnet is fixedly connected in the first mounting cavity. When the fixing rod completely extends out, the first piston plate is in contact with and attracted to the magnet.
[0014] For the convenience of driving the fixing rod to slide, preferably, a second mounting cavity is provided in the first mounting head. A second piston plate is slidably connected in the second mounting cavity. A pressing rod is fixedly connected to the second piston plate. The top of the pressing rod extends above the first mounting head. A first spring is provided in the second mounting cavity. Two ends of the first spring respectively abut against the second piston plate and the bottom wall of the second mounting cavity. The second mounting cavity is filled with hydraulic oil. A temporary storage part for storing hydraulic oil is provided in the first mounting head.
[0015] For the convenience of temporarily storing hydraulic oil, preferably, the temporary storage part includes being provided in the first mounting head and opened in the third mounting cavity. A third piston plate is slidably connected in the third mounting cavity. A second spring is fixedly connected in the third mounting cavity. The second spring is fixedly connected to the bottom of the third piston plate. A first transmission hole for communicating the second mounting cavity and the third mounting cavity is provided in the first mounting head. A second transmission hole for communicating the third mounting cavity and the first mounting cavity is provided in the first mounting head. The orifice of the second transmission hole communicating with the first mounting cavity is smaller than the orifice of the second transmission hole communicating with the third mounting cavity.
[0016] To reduce the frictional force during insertion, preferably, the cavity at the bottom of the third piston plate in the third installation cavity is filled with lubricating oil. A third transmission hole is provided in the first installation head, and the output end of the third transmission hole communicates with the triangular slot. A sealing mold is arranged in the third transmission hole.
[0017] Compared with the prior art, the present invention provides a transmission tower installation component, which has the following
[0018] Beneficial effects:
[0019] 1. For this transmission tower installation component, by inserting the conical platform of the guiding plug into the guiding groove, and then under the guidance of the arc-shaped hypotenuse of the triangular plug plate with a wider top and a narrower bottom and the arc-shaped hypotenuse of the arc-shaped slot with a wider top and a narrower bottom, the alignment between the transmission tower installation component and the bottom tower pole is automatically completed;
[0020] 2. For this transmission tower installation component, when the bottom of the second installation head applies pressure to the pressing rod, during the continuous descent, the pressure applied to the pressing rod drives the second piston plate to descend, and the hydraulic oil inside the second installation cavity is squeezed into the third installation cavity. At the same time, the internal pressure of the space above the third piston plate in the third installation cavity increases, squeezing the second spring. At the same time, the lubricating oil at the bottom of the third piston plate is pressed into the third transmission hole. And as the pressure in the third transmission hole increases, the lubricating oil squeezes and breaks the sealing mold and is discharged through the orifice of the third transmission hole, spraying into the guiding groove, reducing the frictional force between the guiding plug and the guiding groove, reducing the insertion resistance, and providing convenience for assembly;
[0021] 3. For this transmission tower installation component, when the second spring rebounds, it drives the third piston plate to rise, squeezing the hydraulic oil inside the third installation cavity into the first installation cavity, driving the first piston plate to slide. The first piston plate drives the fixing rod to pass through the limiting hole and insert into the fixing hole, automatically completing the fixation of the first installation head and the second installation head, so that there is no need for workers to work at heights, further improving the assembly efficiency and safety.
[0022] Parts not involved in this device are the same as those in the prior art or can be implemented using the prior art. The present invention completes the positioning and installation remotely by the crane operator. After the crane operator completes the alignment and installation, the worker then installs and fixes the plug screw to fix the abutting first installation head and second installation head. On the one hand, it avoids the collision between the transmission tower installation component and the worker due to accidental accidents, while improving the safety of the worker's life. On the other hand, it reduces the alignment difficulty between the transmission tower installation components, improving the alignment efficiency and alignment accuracy. Description of the Drawings

Specific embodiments
[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0032] Embodiment 1:
[0033] Refer to Figures 1-6, a transmission tower installation component, including a hollow column 1, a first mounting head 2 fixedly connected to the top of the hollow column 1, and a second mounting head 3 fixedly connected to the bottom of the hollow column 1. It further includes: a fixing bolt 5 arranged at the bottom of the second mounting head 3, and a jack 4 for the fixing bolt 5 to insert is opened on the first mounting head 2; a limiting portion for locking the fixing bolt 5 is arranged on the first mounting head 2; a guiding plug 9 fixedly connected to the bottom of the second mounting head 3; a guiding groove 7 opened on the first mounting head 2; the guiding groove 7 includes a tapered groove with a narrow upper part and a wide lower part and a cylindrical groove arranged above the tapered groove; the guiding plug 9 includes a cylindrical platform fixedly connected to the second mounting head 3 and a tapered platform integrally formed with the cylindrical platform, the tapered platform is inserted into the tapered groove, and the cylindrical platform is inserted into the cylindrical groove; a triangular insertion plate 10 is fixedly connected to the tapered platform, a limiting plate integrally formed and with a rectangular cross-section is arranged above the triangular insertion plate 10, a triangular insertion slot 8 is opened in the cylindrical groove, and a limiting slot with a rectangular cross-section is arranged above the triangular insertion slot 8, and the triangular insertion plate 10 is inserted into the triangular insertion slot 8, and the limiting plate is inserted into the limiting slot.
[0034] During installation, first complete the basic construction work, including excavating the foundation pit, pouring concrete, installing steel bars, etc. After the basic steps are completed, install the bottom tower pole on the concrete foundation pile. It should be noted that the bottom tower pole is basically the same as the above-mentioned transmission tower installation component, but there is no fixing bolt 5 and guiding plug 9 at the bottom, and the same holes as those on the first mounting head 2 are opened on the second mounting head 3 of the bottom tower pole.
[0035] After the installation of the bottom tower body is completed, lift the above-mentioned transmission tower installation component by a crane, with the first mounting head 2 facing up and the second mounting head 3 facing down. It should be noted that a camera can be installed in the inner hole of the hollow column 1, and this camera can be disassembled, and the picture is transmitted to the display screen in the crane through wireless signals, which is convenient for the crane personnel to align the general position, and is also convenient for the crane operator to align the bottom of the guiding plug 9 with the upper end part of the guiding groove 7, that is, to make the position of the tapered platform above the cylindrical groove. Then, drive the hoisted transmission tower installation component to descend by the crane, insert the tapered platform of the guiding plug 9 into the guiding groove 7, and then under the guidance of the arc-shaped hypotenuse of the upper-wide and lower-narrow triangular insertion plate 10 and the arc-shaped hypotenuse of the upper-wide and lower-narrow triangular insertion slot 8, automatically complete the alignment between the transmission tower installation component and the bottom tower pole. Then, manually fix the adjacent first mounting head 2 and second mounting head 3 with the fixing bolt 5, so as to quickly complete the connection between the bottom tower pole and the transmission tower installation component. The installation of the remaining transmission tower installation components is completed by the same method.
[0036] In summary, the transmission tower installation component can be positioned and installed remotely by the crane operator. After the crane operator completes the alignment and installation, the staff can install and fix the plug to fix the mutually attached first installation head 2 and second installation head 3. On the one hand, it avoids the collision between the transmission tower installation component and the staff due to accidental accidents, while improving the safety of the staff's lives. On the other hand, it reduces the alignment difficulty between the transmission tower installation components, and improves the alignment efficiency and alignment accuracy.
[0037] Referring to Figure 1 , it should be noted that a hole corresponding to the jack 4 can be opened on the second installation head 3. When the fixing bolt 5 is detachable, the hole can be aligned with the jack 4, and then the fixing bolt 5 can be inserted into the two holes, and then fixed with two nuts.
[0038] Embodiment 2:
[0039] Referring to Figures 2-6 , a transmission tower installation component includes a hollow column 1. A first installation head 2 is fixedly connected to the top of the hollow column 1, and a second installation head 3 is fixedly connected to the bottom of the hollow column 1. It further includes: a fixing bolt 5 arranged at the bottom of the second installation head 3, and a jack 4 for inserting the fixing bolt 5 is opened on the first installation head 2; a limiting part for locking the fixing bolt 5 is arranged on the first installation head 2; a guiding plug 9 fixedly connected to the bottom of the second installation head 3; a guiding groove 7 opened on the first installation head 2; the guiding groove 7 includes a tapered groove with a narrow upper part and a wide lower part and a cylindrical groove arranged above the tapered groove; the guiding plug 9 includes a cylindrical platform fixedly connected to the second installation head 3 and a tapered platform integrally formed with the cylindrical platform, the tapered platform is inserted into the tapered groove, and the cylindrical platform is inserted into the cylindrical groove; a triangular plug plate 10 is fixedly connected to the tapered platform, a limiting plate integrally formed and with a rectangular cross-section is arranged above the triangular plug plate 10, a triangular slot 8 is opened in the cylindrical groove, and a limiting slot with a rectangular cross-section is arranged above the triangular slot 8, and the triangular plug plate 10 is inserted into the triangular slot 8, and the limiting plate is inserted into the limiting slot.
[0040] After the installation of the bottom tower body is completed, the above-mentioned transmission tower installation component is lifted by a crane, with the first installation head 2 facing upward and the second installation head 3 facing downward. It should be noted that a camera can be installed in the inner hole of the hollow column 1. This camera is detachable and transmits the image to the display screen in the crane via wireless signal, facilitating the crane operator to align the approximate position and enabling the crane operator to align the bottom of the guiding plug 9 with the upper end of the guiding groove 7, i.e., making the position of the conical platform above the cylindrical groove. Then, the crane is driven to lower the hoisted transmission tower installation component, inserting the conical platform of the guiding plug 9 into the guiding groove 7. Then, under the guidance of the arc-shaped hypotenuse of the triangular plug plate 10 with a wider upper part and a narrower lower part and the arc-shaped hypotenuse of the triangular slot 8 with a wider upper part and a narrower lower part, the alignment between the transmission tower installation component and the bottom tower pole is automatically completed. Then, the worker fixes the adjacent first installation head 2 and second installation head 3 with the fixing bolt 5, thus quickly completing the connection between the bottom tower pole and the transmission tower installation component. The remaining transmission tower installation components are installed using the same method.
[0041] In summary, the transmission tower installation component can be positioned and installed remotely by the crane operator. After the alignment installation is completed by the crane operator, the worker installs and fixes the fixing plug to fix the adjacent first installation head 2 and second installation head 3. On the one hand, it avoids the collision between the transmission tower installation component and the worker due to accidental accidents, while improving the safety of the worker's life. On the other hand, it reduces the alignment difficulty between the transmission tower installation components, improving the alignment efficiency and alignment accuracy.
[0042] Refer to Figures 2-6, furthermore, a limiting hole 6 is formed in the fixing bolt 5, and the fixing bolt 5 is fixedly connected to the bottom of the second mounting head 3. A first mounting cavity 12 is formed in the first mounting head 2. A first piston plate 14 is slidably connected in the first mounting cavity 12. A fixing rod 13 is fixedly connected to the first piston plate 14. The fixing rod 13 extends out of the first mounting cavity 12 and is inserted into the limiting hole 6. A fixing hole 11 is formed in the first mounting head 2. After the fixing rod 13 completely extends out, it extends into the fixing hole 11. A second mounting cavity 16 is formed in the first mounting head 2. A second piston plate 17 is slidably connected in the second mounting cavity 16. A pressing rod 18 is fixedly connected to the second piston plate 17. The top of the pressing rod 18 extends above the first mounting head 2. A first spring 19 is arranged in the second mounting cavity 16. Two ends of the first spring 19 respectively abut against the second piston plate 17 and the bottom wall of the second mounting cavity 16. The second mounting cavity 16 is filled with hydraulic oil. A temporary storage part for storing hydraulic oil is arranged in the first mounting head 2. The temporary storage part includes a part formed in the first mounting head 2 in a third mounting cavity 20. A third piston plate 22 is slidably connected in the third mounting cavity 20. A second spring 21 is fixedly connected in the third mounting cavity 20. The second spring 21 is fixedly connected to the bottom of the third piston plate 22. A first transmission hole 23 for communicating the second mounting cavity 16 and the third mounting cavity 20 is formed in the first mounting head 2. A second transmission hole 24 for communicating the third mounting cavity 20 and the first mounting cavity 12 is formed in the first mounting head 2. The orifice of the second transmission hole 24 communicating with the first mounting cavity 12 is smaller than the orifice of the second transmission hole 24 communicating with the third mounting cavity 20. The cavity in the third mounting cavity 20 located at the bottom of the third piston plate 22 is filled with lubricating oil. A third transmission hole 25 is formed in the first mounting head 2. The output end of the third transmission hole 25 communicates with the triangular slot 8. A mold seal is arranged in the third transmission hole 25.
[0043] When the limit plate is inserted into the limit groove, the fixing bolt 5 first inserts into the jack 4. After the fixing bolt 5 inserts into the limit hole 6, the fixing bolt 5 abuts against the fixing rod 13. After the fixing bolt 5 abuts against the fixing rod 13, the bottom of the second mounting head 3 applies pressure to the pressing rod 18. During the continuous descent, the pressure applied to the pressing rod 18 drives the second piston plate 17 to descend. The descent of the second piston plate 17 causes the first spring 19 to contract and squeezes the hydraulic oil inside the second mounting cavity 16 into the third mounting cavity 20. At the same time, the internal pressure of the space inside the third mounting cavity 20 and above the third piston plate 22 increases, squeezing the second spring 21. At the same time, the lubricating oil at the bottom of the third piston plate 22 is pressed into the third transmission hole 25. As the pressure in the third transmission hole 25 increases, the lubricating oil breaks the mold seal and is discharged through the orifice of the third transmission hole 25, spraying into the guiding groove 7, reducing the friction between the guiding plug 9 and the guiding groove 7, reducing the insertion resistance, and providing convenience for assembly. When the first mounting head 2 and the second mounting head 3 are in contact, the limit hole 6 is aligned with the fixing hole 11. At this time, the second spring 21 rebounds, driving the third piston plate 22 to rise, squeezing the hydraulic oil inside the third mounting cavity 20 into the first mounting cavity 12, driving the first piston plate 14 to slide, and the first piston plate 14 driving the fixing rod 13 to pass through the limit hole 6 and insert into the fixing hole 11, automatically completing the fixation of the first mounting head 2 and the second mounting head 3, thus eliminating the need for workers to work at heights.
[0044] Refer to Figure 6 , a magnet 15 is fixedly connected inside the first mounting cavity 12. When the fixing rod 13 completely extends out, the first piston plate 14 abuts against and attracts the magnet 15. When the first piston plate 14 abuts against the magnet 15, the magnet 15 attracts the first piston plate 14, thereby preventing the first piston plate 14 from moving and further improving the stability of the fixing rod 13.
[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
