Description

TECHNICAL FIELD

[0001] The utility model relates to cement pole technical field, concretely is a cement pole perpendicularity tester. BACKGROUND

[0002] In the power line erection, the cement pole is the commonly used support structure. The perpendicularity of the cement pole is very important for the safe operation of the power line. If the inclination of the pole exceeds the allowable range, it may cause the conductor sagging, uneven stress on the fittings, and even serious accidents such as pole collapse.

[0003] At present, in the prior art, the methods for detecting the perpendicularity of the cement pole mainly include the traditional hanging line plummet method and the use of total station and other measuring instruments. The hanging line plummet method is simple to operate, but the precision is low, and it needs to be tested from the circumference of the cement pole several times, which reduces the speed and accuracy of the detection, and is greatly affected by environmental factors, such as wind, which will make the line plummet swing, resulting in increased measurement error. The total station has high measurement accuracy, but the equipment is expensive and the operation is complex, which requires professional personnel to operate.

[0004] A cement pole perpendicularity detection device is disclosed in the Chinese utility model patent application publication CN202321002195.4, which comprises a base, a lifting assembly is fixedly connected to one side of the upper surface of the base, a measuring assembly is fixedly connected to the other side of the upper surface of the base, and a positioning assembly is fixedly connected to the front of the lifting assembly. Although the cement pole perpendicularity detection device can accurately measure the vertical angle of the cement pole and avoid errors, the cement pole perpendicularity detection device has the disadvantage of being too large to be used in some complex terrain or inconvenient transportation areas.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 6This utility model provides a technical solution: a cement pole verticality tester, comprising a first fixed shell 1 and a second fixed shell 2, wherein connecting rods 4 are fixedly connected to the sides of two support columns 3, and through holes adapted to the connecting rods 4 are opened inside the other two support columns 3. The connecting rods 4 are threaded on the outside and threaded with nuts. First racks 5 are slidably connected inside both the first fixed shell 1 and the second fixed shell 2. Two first racks 5 are slidably connected inside the second fixed shell 2, and one first rack 5 is slidably connected inside the first fixed shell 1. A positioning post 6 is fixedly connected to one end of the first rack 5, and the side of the first rack 5 is provided with... Gear 7 meshes with and connects to the first rack 5. Multiple gears 7 are rotatably connected to the first fixed housing 1 and the second fixed housing 2. Both the first fixed housing 1 and the second fixed housing 2 have annular grooves inside and are rotatably connected to gear rings 8. Gear rings 8 mesh with and connect to gear 7. Annular slide rails 9 are fixedly connected to the tops of both the first fixed housing 1 and the second fixed housing 2. Moving blocks 10 are slidably connected to the tops of the annular slide rails 9. Linear slide rails 23 are fixedly connected to the sides of both the first fixed plate 11 and the second fixed plate 12. Lifting blocks 15 are slidably connected to the sides of the linear slide rails 23. Multiple telescopic rods 17 are fixedly connected to the sides of the lifting blocks 15. A push plate 18 is fixedly connected to the end of the lifting block 15 away from the lifting block 15. A rotating frame 20 is rotatably connected to the side of the push plate 18. A roller 21 is rotatably connected inside the rotating frame 20. Pulleys 13 are rotatably connected to the sides of the first fixed plate 11 and the second fixed plate 12. A pull rope 14 is connected between the two pulleys 13. The lifting block 15 is fixedly connected to the pull rope 14. A spring 19 is sleeved on the outside of the multi-section telescopic rod 17. The two ends of the spring 19 are fixedly connected to the lifting block 15 and the push plate 18, respectively. A scale 22 is fixedly connected to the side of the push plate 18. The scale 22 is slidably connected to the lifting block 15. The lifting block 15 is connected through the first fixed shell 1, the second fixed shell 2, and the gear. The arrangement of wheel 7, toothed ring 8, positioning column 6, rack 5, pulley 13, pull rope 14, multi-section telescopic rod 17, push plate 18, spring 19, rotating frame 20, roller 21, and scale 22 enables the device to center the cement pole before use, avoiding significant positional differences between the testing device and the cement pole that could lead to testing errors. Furthermore, the device can perform both circular and vertical testing of the cement pole during use, thereby reducing testing errors and accurately determining the tilt direction and angle of the cement pole. Moreover, the device requires only mechanical components, without the need for sophisticated electronic components, to test the tilt angle of the cement pole.

[0030] In use, the first fixing shell 1 and the second fixing shell 2 are placed on both sides of the cement pole. Then, the first fixing shell 1 and the second fixing shell 2 are combined. After the combination, the ends of the two connecting rods 4 away from two of the support pillars 3 enter the interior of the other two support pillars 3. Then, the nuts are threaded onto the outer secondary of the connecting rods 4, thereby limiting and fixing the first fixing shell 1 and the second fixing shell 2. Then, one of the racks 5 is pushed, causing one of the gears 7 to rotate. After the gear 7 rotates, one of the gear rings 8 rotates. Then, after the gear ring 8 rotates, it pushes another gear ring 8. Then, the two gear rings 8 cause all three gears 7 to rotate together, thereby moving the three racks 5. After the racks 5 move, they contact the cement pole, so that the user can adjust the overall position of the device so that the three positioning posts 6 contact the cement pole together. At this time, the spring 19 pushes the push plate 18 to move, and the push plate 18 causes the roller 21 to contact the cement pole. At this time, the roller 21 is parallel to the ground. Then, the moving block 10 can be pushed to make The movable block 10 moves around the circular slide rail 9. During movement, the spring 19 continuously pushes the push plate 18 to make the roller 21 fit against the cement pole. Then, the user can observe the position of the scale 22 on the lifting block 15 and infer the tilt direction of the cement pole. The user then moves the movable block 10 to the position of the cement pole's tilt direction, rotates the rotating frame 20 to make the roller 21 vertical, and then pulls the pull rope 14 to raise the lifting block 15. After the lifting block 15 rises, the roller 21 moves on the surface of the cement pole. The user can then infer the tilt angle of the cement pole by observing the movement of the scale 22. This avoids large discrepancies between the position of the testing device and the cement pole, which could lead to testing errors. The device can perform both circular and vertical tests on the cement pole, thereby reducing testing errors and accurately finding the tilt direction and angle of the cement pole. Furthermore, the device does not require sophisticated electronic components; only mechanical components are needed to test the tilt angle of the cement pole.

[0031] Example 2

[0032] Please see Figure 2 , 36. This utility model provides a technical solution: a cement pole verticality tester, wherein two support columns 3 are fixedly connected to the bottom of the first fixed shell 1 and the bottom of the second fixed shell 2, a first fixed plate 11 is rotatably connected to the top of the moving block 10, and a second fixed plate 12 is rotatably connected to the top of the first fixed plate 11. Threaded holes are opened inside the moving block 10 and inside the first fixed plate 11, and bolts are threadedly connected to them. A limiting plate 16 is rotatably connected to the side of the second fixed plate 12. Through the arrangement of the first fixed shell 1, the second fixed shell 2, the support columns 3, the connecting rod 4, and the limiting plate 16, the device can be folded when not in use, thereby reducing the space occupied by the device and making it convenient to carry. This solves the problem that the testing device is too large and inconvenient to use in areas with complex terrain or inconvenient transportation.

[0033] When the device needs to be transported, rotate the limiting plate 16, and then rotate the second fixing plate 12 to rotate the second fixing plate 12 backward, so that the first fixing plate 11 and the second fixing plate 12 fit together. Then rotate the bolt on the outside of the moving block 10 to disengage the bolt from the first fixing plate 11, thereby removing the limitation on the first fixing plate 11. Then rotate the first fixing plate 11 to merge the first fixing plate 11 with the first fixing shell 1, thereby reducing the height of the device. Then, during transportation, the nut on the outside of the connecting rod 4 can be rotated to separate the first fixing shell 1 and the second fixing shell 2, which facilitates the transportation of the device and solves the problem that the test device is too large to be used in areas with complex terrain or inconvenient transportation.
