Description

Technical Field

[0001] This utility model belongs to the field of wooden pole testing technology, specifically relating to a testing device for anti-corrosion wooden poles. Background Technology

[0002] Oiled wooden poles typically refer to wooden utility poles that have been impregnated with preservative oils such as coal tar or creosote. They are mainly used to support power and communication lines. The wood is injected with preservative oil under high temperature and pressure, filling the wood pores and significantly improving its resistance to decay, insects, and moisture, thus extending its service life and making it suitable for harsh outdoor environments. The penetration depth of the preservative oil has a significant impact on the anti-corrosion effect of the wooden pole. Therefore, it is necessary to test the penetration depth of the preservative oil on the wooden pole. During the test, a cross-sectional disc is cut from the end of the wooden pole, and the wood is then treated with a coloring process. By measuring the vertical distance from the outer surface of the wood to the center coloring boundary, and taking the center value from multiple directions, the penetration depth of the preservative oil can be measured. However, since the shape of the cut disc is not necessarily a perfect circle, the center point can easily be inaccurate. If the center point is deviated during the measurement process, it will affect the accuracy of the test results. Utility Model Content

Detailed Implementation

[0018] Please see Figures 1-4The present invention provides the following technical solution: it includes a movable block 1, on the outer side of the movable block 1 are two springs 14 and two springs 15 in opposite positions, on the outer side of the movable block 1 are two measuring rulers 2 and two measuring rulers 3 in opposite positions, one end of the measuring rulers 2 and 3 is respectively provided with a movable plate 21 and a movable plate 31, the end of the springs 14 away from the movable block 1 is fixedly connected to the movable plate 21, the end of the springs 15 away from the movable block 1 is fixedly connected to the movable plate 31, and the ends of the measuring rulers 2 and 3 are respectively rotatably connected to a limiting block 22 and a limiting block 32.

[0019] This embodiment includes a movable block 1. Two opposing springs 14 and two opposing springs 15 are located on the outer side of the movable block 1. The two springs 14 and two springs 15 are on the same straight line. One end of each spring is fixedly connected to the movable block 1. Two opposing measuring rulers 2 and two opposing measuring rulers 3 are also located on the outer side of the movable block 1. The two measuring rulers 2 and two measuring rulers 3 are on the same straight line. The measuring rulers 2 and 3 are perpendicular to each other and have the same size. Both measuring rulers 2 and 3 are made of transparent material. When the measuring rulers 2 and 3 are located on a cross-sectional disc, light passes through them. Measuring rulers 1-2 and 2-3 allow observation of the color boundary on the disc. The distance between the outer surface of the disc and the color boundary can be measured using the scales on measuring rulers 1-2 and 2-3, thus determining the penetration depth of the preservative oil. Using two measuring rulers 1-2 and 2-3 allows for measurements of the wood from different directions, improving data validity. One end of each measuring ruler is equipped with a movable plate 1-21 and a movable plate 2-31, respectively. Movable plate 1-21 is fixedly connected to measuring ruler 1-2, and movable plate 2-31 is fixedly connected to measuring ruler 2-3. Movable plates 1-21 and 2-31 are of the same size. The end of spring 1-14 furthest from movable block 1 is fixedly connected to movable plate 1-21. When the two measuring rulers 1-2... When moving in opposite directions, since the two springs 14 have the same spring constant and natural length, and their fixed points are symmetrical, the movable block 1 will move towards the midpoint between the two measuring rulers 2. The end of the spring 2 15 away from the movable block 1 is fixedly connected to the movable plate 31. The two springs 2 15 have the same spring constant and natural length, and their fixed points are symmetrical. When the two measuring rulers 2 3 move in opposite directions, the movable block 1 will move towards the midpoint between the two measuring rulers 2 3. The ends of the measuring rulers 1 2 and 2 3 are respectively rotatably connected to limit blocks 1 22 and 2 32. Limit blocks 1 22 and 2 32 have the same size. By rotating limit blocks 1 22 or 2 32, the limit blocks 1 22 can be adjusted. The height of limit block 22 and limit block 32 is such that when limit block 22 or limit block 32 rotates downward, the two limit blocks 22 or limit blocks 32 can be clamped on the outside of the disk, and limit blocks 22 and limit blocks 32 correspond to the zero marks of measuring ruler 2 and measuring ruler 3, respectively. When limit blocks 22 and limit blocks 32 are in close contact with the outside of the disk, movable block 1 will be located at the center of the disk, and measuring ruler 2 and measuring ruler 3 will point to the center of the disk, so that measuring ruler 2 and measuring ruler 3 can measure the distance between the outside of the disk and the color development boundary. The two springs 14 and 15 facilitate the positioning of the center point of the disk, so that measuring ruler 2 and measuring ruler 3 point to the center point of the disk.The vertical distance from the outer surface of the wood to the center color boundary can be measured using measuring rulers 1-2 and 2-3, thus allowing for the determination of the preservative oil penetration depth on the wooden rod and improving the accuracy of the test results.

[0020] The bottom of the movable block 1 is provided with several connecting grooves 11, and the inside of the connecting grooves 11 is provided with balls 12; the several connecting grooves 11 are centrally symmetrical, and when the balls 12 are in contact with the disc, the influence of friction on the movement of the movable block 1 can be avoided by the several balls 12.

[0021] Two guide rods 13 are provided on the outer side of each movable block 1. Measuring ruler 1 2 and measuring ruler 2 3 are located between the two guide rods 13. The guide rods 13 are fixedly connected to the movable block 1, and the distance between the two guide rods 13 on the same side matches the width between measuring ruler 1 2 and measuring ruler 2 3.

[0022] Measuring ruler 2 is perpendicular to measuring ruler 3, and guide groove 131 is provided on guide rod 13; the disc can be measured in different directions by measuring ruler 2 and measuring ruler 3, and guide groove 131 is parallel to guide rod 13.

[0023] Both sides of the movable plate 21 and the movable plate 31 are provided with sliders 211, which are slidably connected to the guide groove 131. The sliders 211 are fixedly connected to the movable plate 21 or the movable plate 31. The sliders 211 and the guide groove 131 are matched in size. The movable plate 21 or the movable plate 31 can be guided by the connection between the sliders 211 and the guide groove 131.

[0024] The bottom of the movable plate 21 has several connecting grooves 212, and the inner side of the connecting grooves 212 is provided with ball bearings 213. The dimensions of the connecting grooves 212 and the ball bearings 213 are matched, and the ball bearings 213 can avoid the influence of friction on the movable plate 21 during movement.

[0025] Spring 14 and Spring 25 are both located inside the two guide rods 13, and movable plate 121 and movable plate 231 are both located between the two guide rods 13. Spring 14 and Spring 25 do not contact the guide rods 13. Spring 14 and Spring 25 can drive measuring ruler 12 and measuring ruler 23 to reset after use.

[0026] The working principle and usage process of this utility model are as follows: First, rotate the two limiting blocks 22 downwards. Then, pull the two measuring rulers 2 in opposite directions, clamping the two limiting blocks 22 onto the outside of the disc. Since the two springs 14 have the same stiffness coefficient, the same natural length, and symmetrical fixing points, the movable block 1 will move towards the midpoint between the two measuring rulers 2. Then, pull the two measuring rulers 3 in opposite directions. Since the two springs 15 have the same stiffness coefficient, the same natural length, and symmetrical fixing points, the movable block 1 will move towards the midpoint between the two measuring rulers 3. Through bidirectional positioning, the movable block 1 is aligned with the center point of the disc, and the measuring rulers 2 and 3 will point towards the center point of the disc. The zero mark of the measuring rulers 2 and 3 will then align with the outside of the disc, allowing the measuring rulers 2 and 3 to measure the distance between the outside of the disc and the coloring boundary, thereby achieving the penetration depth of the anti-corrosion oil on the wooden rod.
