Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of power equipment, and particularly relates to a power line support. Background Art
[0002] A power line support (also called a power overhead line support) is a structure used to support power lines and equipment, ensuring that the power lines can be firmly erected in the air and preventing the power lines from loosening or breaking due to factors such as wind and weather. The power line support is the core load-bearing structure in the power transmission system, mainly used to support transmission conductors, ground wires and auxiliary equipment. Since the large-scale development of the power system at the end of the 19th century, the power line support has experienced iterative evolution from wooden poles, reinforced concrete poles to modern steel structures and composite towers. Its design standards have covered the full voltage levels from 10 kV to ±1100 kV, and the structural forms include single poles, portal poles, suspension towers, steel pipe towers and other diverse forms.
[0003] Concrete poles are the most common type of power line support, mainly used in medium and low voltage transmission lines. They have the advantages of strong wind resistance, corrosion resistance and low maintenance costs, and are widely used in suburban and rural areas. The overall structure of concrete poles is relatively simple, mainly consisting of a pole body cast with concrete and structures such as crossarm supports erected in the air. Although the structure of concrete poles is simple, the entire erection process is relatively complex. After the pole is buried, generally, workers need to carry the crossarm and other aerial components of the line support from the ground to the erection position at the top of the pole one by one, or workers lift them to the erection position through guy ropes, and then assemble them in the air one by one. The whole process is not only time-consuming and laborious, but also the frequent handling of heavy objects for high-altitude operations greatly increases the overall construction risk and there are relatively large safety hazards. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a power line support.
[0005] The technical solution adopted to solve the above technical problem is: a power line support, including an installation and positioning component preset on a pole, a quick hanging component is hung on the installation and positioning component, and upper crossarm components are fixedly installed at both ends of the quick hanging component; Bottoms of the two groups of upper crossarm components are fixedly installed with crossarm support components, and bottoms of the two groups of crossarm support components are clamped to the outer wall of the pole. At one end of the two groups of upper crossarm components away from the quick hanging component, suspension tie rods are installed. Bottoms of the two groups of suspension tie rods are suspended with lower crossarm components, and at one end of the two groups of lower crossarm components away from the suspension tie rods, they are clamped to the outer wall of the pole; Two insulators are installed on each of the two upper cross-arm assemblies and the lower cross-arm assemblies, and an automatic lifting assembly for lifting the entire line support is also clamped on the outer wall of the utility pole.
[0006] Furthermore, the installation and positioning assembly includes a positioning ring fixed to the utility pole. A plurality of uniformly distributed hanging holes are provided on the circumferential side of the positioning ring. A hanging groove is provided inside each of the hanging holes. A limiting skirt is also provided on the outer side of the positioning ring to guide the quick hanging assembly to accurately insert into the corresponding hanging hole.
[0007] Through the above technical solution, the installation and positioning assembly is a preset assembly that can cooperate with the quick hanging assembly. It can pre-fix the positioning ring to a position near the top of the utility pole by integral casting or screw fixation. The positioning ring is provided with multiple groups of hanging holes and corresponding hanging grooves. During the subsequent erection process, the quick hanging assembly can be hung in the corresponding hanging holes, thereby realizing the hanging and fixation of the entire line support. In addition, a limiting skirt is provided on the outer side of the positioning ring. By designing the limiting skirt, during the process of the automatic lifting assembly lifting the entire line support, it can play a guiding and limiting role for multiple hanging columns on the quick hanging assembly to ensure that each hanging column can accurately insert into the corresponding hanging hole to complete the entire hanging work.
[0008] Furthermore, the quick hanging assembly includes a first clamping ring and a second clamping ring. Two positioning columns are fixedly connected to the inner sides of the first clamping ring and the second clamping ring. A return spring is installed inside the positioning column. A hanging column is inserted into the inner end of the positioning column. One end of the hanging column is fixedly connected with a limiting block, and the limiting block abuts against the return spring.
[0009] Through the above technical solution, the quick hanging assembly is mainly used to cooperate with the installation and positioning assembly to complete the quick hanging and fixation of the entire line support. During the erection process, the first clamping ring and the second clamping ring are clamped on the outer wall of the utility pole and then fixed by a plurality of bolts. At this time, the inner end faces of the multiple hanging columns are closely attached to the outer wall of the utility pole and drive the corresponding limiting blocks to inwardly compress the return spring. When the automatic lifting assembly drives it to rise as a whole, the inner end faces of the multiple hanging columns will also slide along the outer wall of the utility pole. When the hanging columns rise to the outside of the positioning ring, under the guiding action of the limiting skirt, the multiple hanging columns will accurately move to the top positions of the corresponding hanging holes. When moving to the designated position, under the elastic reaction force of the return spring, the head of the hanging column will insert into the hanging hole. At this time, the automatic lifting assembly will move downward for a certain distance and complete the separation from the cross-arm support assembly. At this time, under the action of the self-weight of the entire line support, it will automatically move downward. At this time, the multiple hanging columns will be stably hung in the corresponding hanging grooves, thereby completing the entire automatic erection work.
[0010] Further, the upper cross arm assembly includes an upper splicing cross arm fixed to one side of the quick hanging assembly. Two first adjustment holes and one first mounting hole are respectively formed in the upper splicing cross arm.
[0011] Through the above technical solution, the upper cross arm assembly mainly serves as a support structure for installing insulators. Two first adjustment holes are formed in the upper splicing cross arm, enabling the installation position of the insulators to be appropriately adjusted to meet different requirements. A first mounting hole is also formed in the upper splicing cross arm for installing a suspension tie rod. The bottom end of the installed suspension tie rod can penetrate the first mounting hole and then be connected to the lower cross arm assembly below, thereby forming an integral structure.
[0012] Further, the cross arm support assembly includes a support frame fixed to the bottom of the upper cross arm assembly. A first hoop ring is fixedly connected to the bottom of the support frame. Two first limiting protrusions are provided inside the first hoop ring. The inner sides of the first limiting protrusions are in contact with the surface of the electric pole. Semi-circular jacking positioning grooves are formed at the front and rear ends of the bottom of the first hoop ring.
[0013] Through the above technical solution, the cross arm support assembly is mainly used for the auxiliary support of the upper cross arm assembly. Cooperating with the upper cross arm assembly, a more stable triangular support structure can be formed. Since the two first hoop rings are clamped around the outer wall of the electric pole, the entire line rack can be in a stable state during the lifting process without shaking, thereby ensuring the stability during the hanging process. In addition, by designing the cross arm support assembly, the stability of the line rack can be better guaranteed, and it will not shake even in windy and rainy weather.
[0014] Further, the suspension tie rod is of a straight tie rod structure.
[0015] Through the above technical solution, the suspension tie rod is mainly used for the installation and fixation of the lower cross arm assembly. When two or more groups of wires need to be vertically wired in the same direction, the lower cross arm assembly can be fixed by the suspension tie rod of the straight tie rod structure at this time, so that the lower cross arm assembly can be quickly installed and fixed, and at the same time, the upper and lower cross arms can form an integral stable structure.
[0016] Further, the suspension tie rod is of an inclined tie rod structure.
[0017] Through the above technical solution, when two or more groups of wires need to be vertically arranged on the electric pole, multiple groups of cross arms need to be set on the electric pole. At the same time, the wiring directions of multiple groups of wires are often different, that is to say, the fixing angles of the vertically arranged cross arms are also different. Therefore, by setting the suspension tie rod of the inclined tie rod structure, on the one hand, the connection and fixation between the upper and lower groups of cross arms can be realized to form an integral stable structure, and at the same time, the angle of the lower cross arm assembly can be quickly fixed, so as to meet the wiring requirements of wires in different directions.
[0018] Further, the lower cross-arm assembly includes a second hoop ring. Two second limiting protrusions are fixedly connected to the inner side of the second hoop ring. The inner sides of the two second limiting protrusions are attached to the surface of the electric pole. One side of the second hoop ring is fixedly connected to a lower splicing cross-arm. Two second adjustment holes and one second installation hole are respectively formed in the lower splicing cross-arm.
[0019] Through the above technical solution, the lower cross-arm assembly has the same function as the upper cross-arm assembly. It also serves as a support structure for installing insulators and using the insulators to fix the wires. The two lower cross-arm assemblies are also held together by two second hoop rings to sleeved on the outer wall of the electric pole. And the ends of the two lower cross-arm assemblies are also suspended and fixed below the upper cross-arm assembly by suspension tie rods, so as to form a stable integral structure between the upper and lower cross-arms, thereby enhancing the strength of the entire power line pole and the ability to resist bad weather to a certain extent. In addition, it should be noted that the lower cross-arm assembly is not an essential part of the line pole and can be assembled or not according to actual wiring requirements.
[0020] Further, the automatic lifting assembly includes a first rotating frame and a second rotating frame that are held on the outer wall of the electric pole. A locking knob for locking and fixing with the second rotating frame is threadedly connected to the side of the first rotating frame away from the hinge end. Motor brackets are installed on both the first rotating frame and the second rotating frame. A traveling wheel is rotatably connected to the inner side of the motor bracket. A transmission bevel gear is installed at one end of the traveling wheel. A reduction motor is installed on the outer side of the motor bracket. A driving bevel gear meshing with the transmission bevel gear is installed at the output end of the reduction motor. A protective cover for protecting the reduction motor is also installed on the motor bracket. Electric telescopic rods are installed on both the first rotating frame and the second rotating frame. A rubber anti-slip push block is fixedly connected to the telescopic end of the electric telescopic rod. A jacking socket and a support block are respectively fixedly connected to the tops of the first rotating frame and the second rotating frame.
[0021] Through the above technical solution, the automatic lifting assembly is mainly used for the automatic lifting of the entire line rack to ensure that the line rack can be automatically installed in place. Specifically, when the entire line rack is assembled, the first rotating rack and the second rotating rack can be held together on the outer wall of the electric pole, and then locked and fixed through the locking knob. At this time, it should be noted that the automatic lifting assembly needs to be located directly below the cross-arm support assembly, and it is necessary to ensure that the lifting socket is inserted into the corresponding lifting positioning groove to ensure the stability and accuracy during the subsequent lifting process, and prevent the line rack from deflecting or displacing during the lifting process. When the preparation is completed, two reduction motors are started simultaneously. When the reduction motor works, it will drive the driving bevel gear to rotate synchronously through its output shaft. When the driving bevel gear rotates, it will drive the driven bevel gear meshing with it to rotate. When the driven bevel gear rotates, it can drive the traveling wheels to rotate. Since the traveling wheels are in close contact with the outer wall of the electric pole, the traveling wheels will drive the entire line rack to lift upward through friction during the upward movement process, and then the line rack can be automatically lifted to the specified installation position on the electric pole. In addition, a set of electric telescopic rods and rubber anti-slip push blocks are installed on both the first rotating rack and the second rotating rack. During the lifting process, the piston rod of the electric telescopic rod will drive the rubber anti-slip push block to extend inward, so that the inner bottom of the rubber anti-slip push block is in contact with the outer wall of the electric pole. At this time, the two are only in contact. When the reduction motor stops working or suddenly stops working due to a fault, the electric telescopic rod will push the rubber anti-slip push block closer to the electric pole, thereby realizing the anti-slip and locking function, preventing the automatic lifting assembly and the entire line rack from suddenly falling, and further improving the safety of the automatic lifting assembly during the working process.
[0022] Further, during the working process, the two lifting sockets are inserted into the corresponding lifting positioning grooves.
[0023] Through the above technical solution, by means of plug-in positioning, the stability of the entire line rack during the rising process can be ensured, and no angular deflection or displacement will occur, thereby ensuring the stability and reliability during the entire installation process.
[0024] The beneficial effects of the present invention are as follows: (1) By designing a simple installation positioning component and a quick hanging component, after the automatic lifting component lifts the entire line rack to the designated position, the line rack can quickly complete the assembly and positioning work by itself without manual operation, which not only saves time and effort but also greatly reduces the risks during the construction process; (2) By arranging a limiting skirt on the outer side of the positioning ring, during the process of lifting and erecting the entire line rack by the automatic lifting component, it can play a guiding and limiting role for multiple hanging columns on the quick hanging component to ensure that each hanging column can accurately insert into the corresponding hanging hole to complete the entire hanging work; (3) By designing an automatic lifting component, workers only need to complete the assembly of the line rack main body on the ground, and then it can replace manual labor to complete the automatic lifting of the entire line rack and ensure that the line rack main body can be automatically installed in place. Its entire installation and disassembly are also very convenient, and the work efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0028] Embodiment 1: As Figure 1 - Figure 2 And Figure 5 - Figure 16As shown in the figure, a kind of power line frame in this embodiment includes an installation and positioning component 1 preset on a telegraph pole 9. The installation and positioning component 1 includes a positioning ring 101 fixed on the telegraph pole 9. A plurality of evenly distributed hanging holes 102 are formed on the circumferential side of the positioning ring 101. A hanging groove 103 is formed on the inner side of each hanging hole 102. An outer side of the positioning ring 101 is further provided with a limiting skirt 104 for guiding the quick hanging component 2 to accurately insert into the corresponding hanging hole 102. The installation and positioning component 1 is a preset component that can cooperate with the quick hanging component 2. The positioning ring 101 can be pre-fixed on the telegraph pole 9 near the top by integral casting or screw fixation. Multiple groups of hanging holes 102 and corresponding hanging grooves 103 are provided on the positioning ring 101. During subsequent erection, the quick hanging component 2 can be hung in the corresponding hanging holes 102, so as to realize the hanging and fixation of the entire line frame. In addition, the outer side of the positioning ring 101 is provided with a limiting skirt 104. By designing the limiting skirt 104, during the process of the automatic lifting component 8 lifting and erecting the entire line frame, it can play a guiding and limiting role for multiple groups of hanging columns 205 on the quick hanging component 2, so as to ensure that each hanging column 205 can accurately insert into the corresponding hanging hole 102 to complete the entire hanging work.
[0029] Regarding the quick hanging component 2, refer to Figure 6 - Figure 11, a quick hanging component 2 is hung on the installation positioning component 1. The quick hanging component 2 includes a first clamping ring 201 and a second clamping ring 202. Two positioning columns 203 are fixedly connected to the inner sides of the first clamping ring 201 and the second clamping ring 202. A return spring 204 is installed in the positioning column 203. A hanging column 205 is inserted into the inner end of the positioning column 203. One end of the hanging column 205 is fixedly connected with a limiting block 206, and the limiting block 206 abuts against the return spring 204. The quick hanging component 2 is mainly used to cooperate with the installation positioning component 1 to complete the quick hanging and fixing of the entire line rack. During the erection process, the first clamping ring 201 and the second clamping ring 202 are held against the outer wall of the electric pole 9, and then fixed by a plurality of bolts. At this time, the inner end faces of the plurality of hanging columns 205 are closely attached to the outer wall of the electric pole 9 and drive the corresponding limiting blocks 206 to inwardly press the return spring 204. When the automatic lifting component 8 drives its whole body to rise, the inner end faces of the plurality of hanging columns 205 will also slide along the outer wall of the electric pole 9. When the hanging column 205 rises to the outside of the positioning ring 101, under the guiding action of the limiting skirt 104, the plurality of hanging columns 205 will accurately move to the top positions of the corresponding hanging holes 102. When moving to the designated position, under the elastic reaction force of the return spring 204, the head of the hanging column 205 will be inserted into the hanging hole 102. At this time, the automatic lifting component 8 will move downward for a certain distance and be separated from the cross arm support component 4. At this time, under the action of the self-gravity of the entire line rack, it will automatically move downward. At this time, the plurality of hanging columns 205 will be firmly hung in the corresponding hanging grooves 103, thus completing the entire automatic erection work.
[0030] Regarding the upper cross arm component 3, refer to Figure 10 - Figure 11 , upper cross arm components 3 are fixedly installed at both ends of the quick hanging component 2; the upper cross arm component 3 includes an upper splicing cross arm 301 fixed to one side of the quick hanging component 2. Two first adjustment holes 302 and one first installation hole 303 are respectively opened on the upper splicing cross arm 301. The upper cross arm component 3 mainly serves as a support structure for installing the insulator 7. Two first adjustment holes 302 are opened on the upper splicing cross arm 301, so that the installation position of the insulator 7 can be appropriately adjusted to meet different requirements. A first installation hole 303 is also opened on the upper splicing cross arm 301 for installing the suspension tie rod 5. The bottom end of the installed suspension tie rod 5 can penetrate through the first installation hole 303 and then be connected to the lower cross arm component 6 below, so as to form an integral structure.
[0031] Regarding the cross arm support component 4, refer to Figure 10 - Figure 11, at the bottom of both groups of upper cross-arm assemblies 3, there are cross-arm support assemblies 4 fixedly installed, and the bottom ends of the two cross-arm support assemblies 4 are clamped to the outer wall of the utility pole 9. The cross-arm support assembly 4 includes a support frame 401 fixed to the bottom of the upper cross-arm assembly 3. At the bottom of the support frame 401, there is a first clamping ring 402 fixedly connected. Inside the first clamping ring 402, there are two first limiting protrusions 403. The inner sides of the first limiting protrusions 403 are in contact with the surface of the utility pole 9. At the front and rear ends of the bottom of the first clamping ring 402, there are semi-circular jacking positioning grooves 404. The cross-arm support assembly 4 is mainly used for the auxiliary support of the upper cross-arm assembly 3. Cooperating with the upper cross-arm assembly 3, it can form a more stable triangular support structure. Since the two first clamping rings 402 are clamped to the outer wall of the utility pole 9, the entire line rack can be in a stable state during the lifting process without shaking, thus ensuring the stability during the hanging process. In addition, by designing the cross-arm support assembly 4, the stability of the line rack can be better ensured, and it will not shake even in windy and rainy weather.
[0032] Regarding the suspension tie rod 5, refer to Figure 12 , at one end of both groups of upper cross-arm assemblies 3 away from the quick connection assembly 2, there are suspension tie rods 5 installed. The suspension tie rod 5 has a straight rod structure. The suspension tie rod 5 is mainly used for the installation and fixation of the lower cross-arm assembly 6. When two or more wires need to be vertically wired in the same direction, at this time, the lower cross-arm assembly 6 can be fixed by the straight rod structure suspension tie rod 5, so that the lower cross-arm assembly 6 can be quickly installed and fixed, and at the same time, the upper and lower cross-arms can form an integrated stable structure.
[0033] Regarding the lower cross-arm assembly 6, refer to Figure 12, the bottom ends of the two groups of suspension tie rods 5 are both suspended with lower cross-arm assemblies 6, and the ends of the two groups of lower cross-arm assemblies 6 away from the suspension tie rods 5 are clamped to the outer wall of the utility pole 9; the lower cross-arm assembly 6 includes a second clamping ring 601, and two second limiting protrusions 602 are fixedly connected to the inner side of the second clamping ring 601. The inner sides of the two second limiting protrusions 602 are in contact with the surface of the utility pole 9. One side of the second clamping ring 601 is fixedly connected with a lower splicing cross-arm 603. Two second adjustment holes 604 and one second installation hole 605 are respectively formed in the lower splicing cross-arm 603. The lower cross-arm assembly 6 has the same function as the upper cross-arm assembly 3. It is also used as a support structure for installing insulators 7 and for fixing electric wires by using the insulators 7. The two groups of lower cross-arm assemblies 6 are also clamped to each other through two second clamping rings 601 to be sleeved on the outer wall of the utility pole 9, and the ends of the two groups of lower cross-arm assemblies 6 are also suspended and fixed below the upper cross-arm assembly 3 through the suspension tie rods 5, so as to form a stable integral structure between the upper and lower cross-arms, thereby enhancing the strength of the entire power line support and its ability to resist bad weather to a certain extent; in addition, it should be noted that the lower cross-arm assembly 6 is not an essential part of the line support, and whether it is assembled can be determined according to actual wiring requirements.
[0034] Two insulators 7 are installed on both the two groups of upper cross-arm assemblies 3 and the lower cross-arm assemblies 6. The insulator 7 is an important electrical equipment in the line support. Its main function is to support the conductor. The insulator 7 can fix the power line (such as a cable, a conductor) on the cross-arm, maintain the stability and correct height of the conductor. At the same time, the insulating property of the insulator 7 can effectively isolate the current, prevent the current from flowing to the ground or other parts that should not be electrified through the support structure, so as to reduce the fault risk of the power system.
[0035] Regarding the automatic lifting assembly 8, refer to Figure 13 - Figure 16, an automatic lifting assembly 8 for lifting the entire line support is also clamped to the outer wall of the utility pole 9. The automatic lifting assembly 8 includes a first rotating frame 801 and a second rotating frame 802 clamped to the outer wall of the utility pole 9. A locking knob 803 for locking and fixing with the second rotating frame 802 is threadedly connected to one side of the first rotating frame 801 away from the hinged end. Motor brackets 804 are installed on both the first rotating frame 801 and the second rotating frame 802. A traveling wheel 805 is rotatably connected to the inner side of the motor bracket 804. A transmission bevel gear 806 is installed at one end of the traveling wheel 805. A reduction motor 807 is installed on the outer side of the motor bracket 804. A driving bevel gear 808 meshing with the transmission bevel gear 806 is installed at the output end of the reduction motor 807. A protective cover 809 for protecting the reduction motor 807 is also installed on the motor bracket 804. Electric telescopic rods 810 are installed on both the first rotating frame 801 and the second rotating frame 802. A rubber anti-slip push block 811 is fixedly connected to the telescopic end of the electric telescopic rod 810. A jacking socket 812 and a support block 813 are respectively fixedly connected to the tops of the first rotating frame 801 and the second rotating frame 802. The automatic lifting assembly 8 is mainly used for the automatic lifting of the entire line support to ensure that the line support can be automatically installed in place. Specifically, when the entire line support is assembled, the first rotating frame 801 and the second rotating frame 802 can be clamped to the outer wall of the utility pole 9 and then locked and fixed through the locking knob 803. At this time, it should be noted that the automatic lifting assembly 8 needs to be located directly below the cross-arm support assembly 4, and it is necessary to ensure that the jacking socket 812 is inserted into the corresponding jacking positioning groove 404 to ensure the stability and accuracy during the subsequent lifting process and prevent the line support from deflecting or displacing during the lifting process. When the preparation is completed, two reduction motors 807 are started simultaneously. When the reduction motor 807 is working, it will drive the driving bevel gear 808 to rotate synchronously through its output shaft. When the driving bevel gear 808 rotates, it will drive the meshing transmission bevel gear 806 to rotate. When the transmission bevel gear 806 rotates, it can drive the traveling wheel 805 to rotate. Since the traveling wheel 805 is in close contact with the outer wall of the utility pole 9, the traveling wheel 805 will drive the entire line support to lift upward through friction during the upward movement process, and then the line support can be automatically lifted to the designated installation position on the utility pole 9. In addition, a set of electric telescopic rods 810 and rubber anti-slip push blocks 811 are installed on both the first rotating frame 801 and the second rotating frame 802. During the lifting process, the piston rod of the electric telescopic rod 810 will drive the rubber anti-slip push block 811 to extend inward, so that the inner bottom of the rubber anti-slip push block 811 is in contact with the outer wall of the utility pole 9. At this time, the two are only in contact. When the reduction motor 807 stops working or suddenly stops working due to a fault, the electric telescopic rod 810 will push the rubber anti-slip push block 811 closer to the utility pole 9, thus realizing the anti-slip and locking function and preventing the automatic lifting assembly 8 and the entire line support from suddenly falling.Thereby further improving the safety of the automatic lifting assembly 8 during operation.
[0036] In this embodiment, further, during operation, the two lifting sockets 812 are inserted into the corresponding lifting positioning grooves 404. By means of plug-in positioning, the stability of the entire line rack during the rising process can be ensured, and no angular deflection or displacement will occur, thereby ensuring the stability and reliability during the entire installation process.
[0037] Embodiment 2: Refer to Figure 3 - Figure 4 , the difference between this embodiment and the first embodiment is that the suspension tie rod 5 is of an inclined tie rod structure. When two or more groups of electric wires need to be vertically arranged on the utility pole 9, multiple groups of cross arms need to be provided on the utility pole 9. At the same time, the wiring directions of multiple groups of electric wires are often different, that is to say, the fixed angles of the vertically arranged cross arms are also different. Therefore, by providing the suspension tie rod 5 of the inclined tie rod structure, on the one hand, the connection and fixation between the upper and lower groups of cross arms can be realized, so that an integral stable structure is formed, and at the same time, the angle of the lower cross arm assembly 6 can be quickly fixed, so as to meet the wiring requirements of electric wires in different directions.
[0038] The working principle is as follows. Before burying the pole, first pre-fix the installation positioning assembly 1 on the utility pole 9. When burying the utility pole 9, it is also necessary to determine the angle of the hanging hole 102 in advance to ensure that the installation angle of the entire line rack meets the requirements in the follow-up; After the utility pole 9 is buried, according to the design requirements, structures such as the quick hanging assembly 2, the upper cross arm assembly 3, and the cross arm support assembly 4 are pre-assembled manually at the ground position, so that the whole is sleeved outside the utility pole 9. Then, the first rotating frame 801 and the second rotating frame 802 are held together on the outer wall of the utility pole 9, and then locked and fixed through the locking knob 803, and it is necessary to ensure that the lifting socket 812 is inserted into the corresponding lifting positioning groove 404; Subsequently, the automatic lifting assembly 8 can be started, thereby lifting the entire line rack upward. When the hanging column 205 rises to the outside of the positioning ring 101, under the guiding action of the limiting skirt 104, multiple hanging columns 205 will accurately move to the top positions of the corresponding hanging holes 102. When moving to the specified position, under the elastic reverse pushing action of the return spring 204, the head of the hanging column 205 will be inserted into the hanging hole 102. At this time, the automatic lifting assembly 8 will move downward for a certain distance and disengage from the cross arm support assembly 4. At this time, under the action of the self-weight of the entire line rack, it will automatically move downward. At this time, multiple hanging columns 205 will be firmly hung in the corresponding hanging grooves 103, thereby completing the entire automatic erection work; In the case where the lower cross-arm assembly 6 is not installed on the line rack, the automatic lifting assembly 8 can be directly controlled to execute the return program, so that it automatically descends to the ground position, and then it can be disassembled manually; when the lower cross-arm assembly 6 is installed on the line rack, since the automatic lifting assembly 8 is located between the lower cross-arm assembly 6 and the cross-arm support assembly 4, at this time the automatic lifting assembly 8 cannot return automatically. It is necessary for workers to climb to the top of the electric pole 9 during subsequent wiring and bring it back to the ground by disassembling it after the wiring is completed.
[0039] As described above, it is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
