Description

Technical Field

[0001] This utility model relates to the field of pole fixing devices, specifically a fixing device for prestressed concrete poles. Background Technology

[0002] Prestressed concrete poles are cement-based poles whose performance is enhanced through pre-stressing technology. They are widely used in power, communications, and other fields. During the manufacturing process, the internal steel reinforcement is pre-stretched before the concrete is poured. This tension is released after the concrete hardens, placing the concrete under compression. Advantages of prestressed concrete poles include improved crack resistance, bending strength that is 1.5-2 times that of ordinary poles, and corrosion resistance exceeding 50 years as shown in salt spray tests. The fixing device for prestressed concrete poles refers to the device used to securely install electrical equipment on the poles.

[0003] In existing technology, the fixing device for prestressed concrete poles typically consists of a crossarm with a flange at one end. The flange has pre-drilled through holes. During installation, screw holes are drilled on the surface of the prestressed concrete pole, with the screw holes corresponding to the through holes. Screws are then passed through the through holes and tightened into the screw holes, thus installing the crossarm onto the pole. Similarly, through holes are pre-drilled on the crossarm and electrical equipment. By passing bolts through the through holes on the crossarm and electrical equipment and tightening nuts, the electrical equipment can be fixed to the prestressed concrete pole. This fixing method is simple in structure and provides a stable installation.

[0004] However, the existing fixing devices for prestressed concrete poles require drilling screw holes in the pole for installation between the crossarm and the pole. This damages the surface structure of the pole, reduces its strength, and shortens its service life. Utility Model Content

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: a fixing device for a prestressed concrete pole, comprising: a mounting plate 1, wherein the mounting plate 1 is provided in several groups, and the several groups of mounting plates 1 are installed together by connecting rods 3, wherein the top of the uppermost group of mounting plates 1 is provided with a top rod 2, and a cross arm 4 is fixed on the surface of the mounting plate 1, and an equipment mounting hole 5 is provided on the surface of the cross arm 4.

[0023] In actual use, the two sets of top rods 2 are assembled together, and a set of mounting plates 1 is installed at the bottom of the top rods 2. Then, as needed, multiple sets of mounting plates 1 can be hoisted below the top set of mounting plates 1 using multiple sets of connecting rods 3. A cross arm 4 is fixed on the surface of the mounting plate 1, and equipment mounting holes 5 are opened on the surface of the cross arm 4. Electrical equipment can be installed on the cross arm 4 by the cooperation of bolts and nuts and equipment mounting holes 5. This achieves the fixed installation between the electrical equipment and the prestressed concrete pole without the need to drill holes in the pole, ensuring the strength of the pole and extending its service life.

[0024] Example 2: Based on Example 1, in order to realize the assembly of mounting plate 1 and top rod 2 and the hoisting between multiple sets of mounting plates 1, mounting plate 1 includes: a first arc-shaped plate 6 and a second arc-shaped plate 7, both of which are semi-circular annular plate structures; the top rod 2 has a "Z"-shaped plate structure; the connecting rod 3 has a "C"-shaped plate structure; two sets of top rods 2 are provided; splicing installation holes 8 are opened on the surfaces of the two sets of top rods 2 that are close to each other, as well as on the surfaces of the first arc-shaped plate 6 and the second arc-shaped plate 7; the splicing installation holes 8 are provided in... The device is equipped with a movable splicing installation bolt 9. A splicing installation nut 10 is installed on the surface of the splicing installation bolt 9 by means of a thread. Mounting seats 13 are fixed on the surfaces of the first arc plate 6 and the second arc plate 7. The mounting seats 13 are rectangular block structures. Threaded grooves 14 are opened at both the upper and lower ends of the mounting seats 13. Screws 16 are rotatably connected to the upper and lower ends of the connecting rod 3 and one end of the top rod 2. The screws 16 are installed in the threaded grooves 14 by means of a thread. Bolt anti-loosening washers 12 are fitted on the rod body of the splicing installation bolt 9.

[0025] During installation, one set of push rods 2 is installed onto the mounting base 13 fixed to the surface of a first arc-shaped plate 6 using screws 16 and threaded grooves 14. The other set of push rods 2 is installed onto the mounting base 13 fixed to the surface of a second arc-shaped plate 7. Then, the first arc-shaped plate 6 and the second arc-shaped plate 7 are joined together, aligning the two sets of splicing mounting holes 8 on the surface of the first arc-shaped plate 6 with the two sets of splicing mounting holes 8 on the surface of the second arc-shaped plate 7. After alignment, the first arc-shaped plate 6, the second arc-shaped plate 7, and the two sets of push rods 2 are assembled using splicing mounting bolts 9 and splicing mounting nuts 10, thus assembling the first arc-shaped plate 6, the second arc-shaped plate 7, and the two sets of push rods 2. Plate 6 and the second arc-shaped plate 7 form mounting plate 1 and are installed on the pole. Then, by using the screw 16 and threaded groove 14 at the top of the connecting rod 3, the two sets of connecting rods 3 are installed below the already installed mounting plate 1. By using the screw 16 and threaded groove 14 at the bottom of the connecting rod 3, the other set of first arc-shaped plates 6 and second arc-shaped plates 7 are installed below the connecting rod 3 respectively. Then, the first arc-shaped plates 6 and second arc-shaped plates 7 are assembled to form a new set of mounting plates 1, so that the other set of mounting plates 1 can be hoisted below the previous set of mounting plates 1. By repeating the above operation, multiple sets of mounting plates 1 can be hoisted as needed.

[0026] Example 3: Based on Example 2, in order to prevent loosening of the threads between the splicing installation bolt 9 and the splicing installation nut 10, a sleeve plate 11 is fixed on the surface of the first arc plate 6 and one of the top rods 2. The nut of the splicing installation bolt 9 has a hexagonal prism structure, and the sleeve plate 11 has a ring structure. The inner ring of the sleeve plate 11 cooperates with the nut of the splicing installation bolt 9. A bolt anti-loosening washer 12 is sleeved on the rod body of the splicing installation bolt 9.

[0027] The nut of the splicing installation bolt 9 is inserted into the inner ring of the sleeve plate 11. The sleeve plate 11 is fixed on the surface of the first arc plate 6 or the top rod 2, thereby limiting the splicing installation bolt 9 circumferentially. A bolt anti-loosening washer 12 is fitted on the splicing installation bolt 9. After the splicing installation nut 10 is tightened onto the splicing installation bolt 9 through the threaded connection, the splicing installation nut 10 exerts a large pressure on the bolt anti-loosening washer 12, causing the bolt anti-loosening washer 12 to be compressed. Under its own elasticity, the bolt anti-loosening washer 12 generates a large reaction force on the splicing installation nut 10, thereby generating a large frictional force between the splicing installation nut 10 and the bolt anti-loosening washer 12. The frictional force provides circumferential limitation for the splicing installation nut 10.

[0028] Example 4: Based on Example 3, in order to reduce wear on the prestressed concrete pole, anti-slip pads 15 are fixed on the surfaces of the mounting plate 1, top rod 2 and connecting rod 3 near the prestressed concrete pole.

[0029] Anti-slip pads 15 are fixed on the surfaces of the mounting plate 1, top rod 2, and connecting rod 3 near the prestressed concrete pole, so that more wear occurs on the anti-slip pads 15, thereby reducing the wear of the prestressed concrete pole.

[0030] In actual use, two sets of top rods 2 are assembled together, and a set of mounting plates 1 is installed at the bottom of the top rods 2. Then, as needed, multiple sets of mounting plates 1 can be hoisted below the top set of mounting plates 1 using multiple sets of connecting rods 3. A cross arm 4 is fixed on the surface of the mounting plate 1, and equipment mounting holes 5 are opened on the surface of the cross arm 4. Electrical equipment can be installed on the cross arm 4 by cooperating with bolts and nuts and the equipment mounting holes 5, thus realizing the fixed installation between the electrical equipment and the prestressed concrete pole. There is no need to drill holes in the pole, which ensures the strength of the pole and extends its service life. During installation, one set of top rods 2 is installed on a first arc using the cooperation of screws 16 and threaded grooves 14. On the mounting base 13 fixed to the surface of the first arc plate 6, another set of top rods 2 are installed onto the mounting base 13 fixed to the surface of the second arc plate 7. Then, the first arc plate 6 and the second arc plate 7 are spliced ​​together, aligning the two sets of splicing mounting holes 8 on the surface of the first arc plate 6 with the two sets of splicing mounting holes 8 on the surface of the second arc plate 7. After alignment, the first arc plate 6, the second arc plate 7, and the two sets of top rods 2 are assembled using splicing mounting bolts 9 and splicing mounting nuts 10, so that the first arc plate 6 and the second arc plate 7 form a mounting plate 1 and are installed on the pole. Then, the two sets of connecting rods 3 are installed by the cooperation of the screw 16 and the threaded groove 14 at the top of the connecting rod 3. Below the already installed mounting plate 1, using the engagement of the screw 16 and threaded groove 14 at the bottom of the connecting rod 3, another set of first arc-shaped plates 6 and second arc-shaped plates 7 are respectively installed below the connecting rod 3. Then, these first arc-shaped plates 6 and second arc-shaped plates 7 are assembled to form a new set of mounting plates 1, allowing another set of mounting plates 1 to be hoisted below the previous set. Repeating the above operation allows for the hoisting of multiple sets of mounting plates 1 as needed. The nuts of the splicing mounting bolts 9 are inserted into the inner ring of the sleeve plate 11, which is fixed to the surface of the first arc-shaped plate 6 or the top rod 2, thereby circumferentially limiting the splicing mounting bolts 9. Bolt anti-loosening washers are then fitted onto the splicing mounting bolts 9. 12. After the splicing installation nut 10 is tightened onto the splicing installation bolt 9 via threaded connection, the splicing installation nut 10 exerts a large pressure on the bolt anti-loosening washer 12, causing the bolt anti-loosening washer 12 to be compressed. Under its own elasticity, the bolt anti-loosening washer 12 generates a large reaction force on the splicing installation nut 10, thereby generating a large frictional force between the splicing installation nut 10 and the bolt anti-loosening washer 12. The frictional force provides circumferential restraint to the splicing installation nut 10. Anti-slip pads 15 are fixed on the surfaces of the mounting plate 1, top rod 2, and connecting rod 3 near the prestressed concrete pole, so that more wear occurs on the anti-slip pads 15, thereby reducing the wear of the prestressed concrete pole.
