Description

Technical Field

[0001] The utility model relates to the technical field of angle steel detection for iron towers, in particular to a qualified measuring platform for angle steel for iron towers. Background Art

[0002] In the manufacturing and construction of steel towers, angle steel is an essential component of the tower structure. The dimensional accuracy and angular precision of angle steel directly impact the stability and safety of the tower. Traditional angle steel inspection methods rely primarily on manual measurement, which is not only inefficient but also difficult to ensure accurate and consistent measurement results due to human factors.

[0003] Poor versatility: Many measuring devices can only measure angle steels of specific specifications. Different measuring tools or devices need to be replaced for angle steels of different specifications, which lacks flexibility and versatility.

[0004] Complex operation: Some automated measurement equipment is complex to operate and requires professional technicians to operate, which increases the usage threshold and training costs.

[0005] Limited measurement range: Some measuring devices can only measure a single parameter of angle steel, such as side length or angle, and cannot meet multiple measurement needs at the same time.

[0006] To address the aforementioned issues of poor versatility, complex operation, and limited measurement range, a search revealed CN204269028U (hereinafter referred to as "the solution"), which discloses a quick-check ruler for angle steel used in towers. This ruler features a main plate and a secondary plate mounted on either side of the main body, with a partition forming a stepped inspection pool in between to match the side lengths of angle steels of varying specifications. A test slot is located at the front of the ruler for measuring the edge thickness of the angle steel. This design aims to quickly and accurately verify angle steel dimensions, reduce labor costs, and improve inspection efficiency.

[0007] In this method, the inspection process involves inserting the tower angle steel into a correspondingly sized inspection well. If the angle steel's side length exactly matches the standard dimensions, it will not fit into the inspection well. Conversely, if the angle steel's side length is smaller than the standard dimensions, meaning it exhibits a negative deviation, it will fit. However, this inspection ruler design has obvious limitations; this method cannot measure angle steel with positive deviations in length. Utility Model Content

[0033] A qualified measuring platform for angle steel used in iron towers, comprising:

[0035] There is a length fixing ruler 11 on the front side of the base plate 1, and a first sliding device 8 is provided next to the length fixing ruler 11.

[0036] In the specific implementation process, Figure 1 、 Figure 4 、 Figure 5 As shown, the first sliding device 8 is equipped with a first sliding rail 83, which passes through the first sliding plate 81 and is embedded in the first sliding groove 14 on the base plate 1, and both ends of the first sliding rail 83 extend out of the base plate 1, and first gaskets 85 are respectively installed at the extensions of both ends.

[0037] In the specific implementation process, Figure 4 、 Figure 5 As shown, the first sliding device 8 is also equipped with a first screw rod 82, which passes through the first sliding plate 81 and the base plate 1. The smooth side of the first screw rod 82 is fixedly connected to the first knob 84. The first screw rod 82 is provided with a first screw rod thread 821, which is threadedly connected to the first sliding plate 81. The first screw rod passes through two first washers 85. The end of the first screw rod 82 is equipped with a first screw rod nut 87 to fix the first screw rod 82 on the base plate 1.

[0038] In the specific implementation process, Figure 4 As shown, the radius of the first screw rod 82 portion from the first knob 84 to the first gasket 85 is greater than the radius of the through hole of the first gasket 85 .

[0039] In the specific implementation process, Figure 1 , Figure 2 As shown, the substrate 1 is provided with a testing slot 6 , and a second sliding device 9 is provided on one side of the testing slot 6 .

[0040] In the specific implementation process, Figure 6As shown, the second sliding device 9 is equipped with a second slide rail 92. The second slide rail 92 passes through the second sliding plate 61 and is embedded in the second slide groove 15 on the base plate 1. The second sliding plate 61 points to the scale of the thickness fixed ruler 12. The two ends of the second slide rail 92 extend beyond the base plate 1 and the fixed plate 16, and second gaskets 96 are respectively installed at the extension points of the two ends. The second slide rail 92 has threads at both ends, and the second nut 85 is tightened on these threads. The second sliding device 9 is fixed in the second slide groove 15 of the base plate 1 through the second gaskets 96 on both sides.

[0041] In the specific implementation process, Figure 6 As shown, the second sliding device 9 is also equipped with a second screw rod 91, which passes through the second sliding plate 61 and the base plate 1. The smooth side of the second screw rod 91 is fixedly connected to a second knob 94. The second screw rod 91 is provided with a second screw rod thread 93, which is threadedly connected to the second sliding plate 61. The second screw rod passes through two second washers 96. The end of the second screw rod 91 is equipped with a second screw rod nut 97 to fix the second screw rod 91 on the base plate 1.

[0042] In the specific implementation process, Figure 6 As shown, the radius of the second screw rod 91 from the second knob 94 to the second gasket 96 is greater than the radius of the through hole of the second gasket 96 .

[0043] In the specific implementation process, Figure 2 As shown, if the inspection slot 6 does not have a notch with a size corresponding to the thickness of the angle steel edge of the tower,

[0044] In the specific implementation process, Figure 1 , Figure 3 As shown, the protractor 7 is installed on one side of the substrate 1. The substrate 1 on the upper side of the protractor 7 is provided with a width fixed ruler 13. A rotating ruler 71 is provided with the center of the protractor 7 as the rotation axis. The rotating ruler 71 is marked with a scale 72 and is used in conjunction with the protractor 7.

[0045] The working principle of this embodiment is as follows: when measuring the length of the angle steel, the operator inserts the angle steel into the inspection pool 5 of corresponding size composed of the main board 2 and the partition 4 for inspection. Because the size of each inspection pool 5 matches the standard size of the side length of angle steels of different specifications, if the negative deviation size of the side length of the angle steel meets the standard, the angle steel cannot be inserted into the inspection pool 5. If the negative deviation size of the side length of the angle steel is not standard, that is, the side length of the angle steel is smaller than the standard side length, the angle steel can be inserted into the inspection pool 5. If the precise length of the angle steel is to be measured, the angle steel is inserted into the angle steel length inspection pool formed by the first sliding plate 81 and the main board 2. By rotating the knob 84 clockwise to move the first sliding plate 81 to the left to fit the angle steel, the scale on the length fixing ruler 11 pointed to by the first sliding plate 81 is the precise length of the angle steel. If you want to measure whether the edge thickness of the angle steel meets the standards, insert the angle steel into the inspection slot 6 of the corresponding size. Because the width of each inspection slot 6 matches the standard size of the edge thickness of the angle steel, if the edge thickness of the angle steel is standard, the angle steel cannot be inserted into the inspection slot 6. If the edge thickness of the angle steel is not standard, the edge thickness of the angle steel is less than the standard edge thickness, the angle steel used for the tower can be inserted into the inspection slot 6; if you want to measure the precise thickness of the two angle steels, insert the edge of the angle steel into the angle steel thickness inspection pool formed by the second sliding plate 61 and the fixed plate 16, and move the second sliding plate 61 forward to fit the angle steel by rotating the knob 94 counterclockwise. The scale on the thickness fixing ruler 12 pointed to by the second sliding plate 61 is the precise thickness of the angle steel. If you want to measure the side width and external angle of the angle steel, place the angle steel at the angle between the base plate 1 and the rotating ruler 71, adjust the rotating ruler 71 to fit the angle steel, and the degree of the rotating ruler 71 fitting the protractor 7 is the external angle of the angle steel. At this time, the width fixed ruler 13 and the fixed ruler scale 72 correspond to the width of the two sides of the angle steel.

[0046] The utility model is used to inspect the side length and side thickness of the angle steel for the tower with deviations and the external angle of the angle steel. When used, it is first required that the angle steel for the tower to be inspected is in a normal state without abnormal phenomena such as bending deformation or notches. If the side length of the angle steel for the tower is measured to be qualified, the requirements for the angle steel for the tower are relatively high during use. This also requires the manufacturers of the angle steel for the tower to reduce the deformation amount during the production and transportation of the angle steel for the tower and improve the product qualification rate. This is a strict requirement for steel and also a strict requirement for the production of towers.

[0047] According to actual needs, the above-mentioned quick inspection ruler for qualified angle steel for iron tower can be further optimized and / or improved: as shown in Figure 1, the inspection ruler body 1, main plate 2, sub-plate 3 and partition 4 are all made of steel plates to ensure that the present invention will not be deformed or inaccurate due to large force, large number, and large number of inspections during use.

[0048] The utility model can not only be used for measuring the side length, side thickness and side width of angle steel for iron towers, but also can be used for measuring the side length and side thickness of any angle steel.

[0049] The present invention adopts a precise screw and slide rail structure to accurately adjust the position of the sliding plate. By setting the main board 1 and the partition 4, the length of the angle steel can be quickly measured, solving the problem of complicated operation. By setting the first sliding device 8 and the length fixing ruler 11, the length of the angle steel can be accurately measured. By setting the inspection groove 6, the thickness of the angle steel can be quickly measured, solving the problem of poor versatility. By setting the second sliding device 9 and the thickness fixing ruler 12, the thickness of the angle steel can be accurately measured, improving the measurement accuracy of the present invention. By cooperating with the width fixing ruler 13, the protractor 7 and the rotating fixing ruler 71, the side width and external angle of the angle steel can be measured. It can accurately measure the side length, side width, side thickness and external angle of the angle steel used for the iron tower, solving the problem of limited measurement range, improving the versatility of the present invention, effectively reducing the measurement error range, and improving the accuracy of measurement.

[0050] This utility model is highly versatile and suitable for angle steels of various specifications. It is easy to operate, reducing reliance on specialized personnel and lowering labor costs. Its compact and durable structure improves work efficiency and tower stability, while also facilitating calibration and maintenance. This improves the efficiency and accuracy of angle steel measurement while reducing operational difficulty and costs. The relatively high measurement accuracy prevents angle steel length deviations and enhances the stability of angle steels when used on towers.

[0051] The remaining parts not described in this utility model are existing or well-known technologies.
