[0002] Currently, steel structures involve numerous connection and mounting holes, with the majority occurring at the ends of steel beam webs. Because the size and relative positioning of these holes can impact the success of on-site assembly, workshop staff and quality inspectors rely on squares and tape measures to measure the hole diameters and spacing. However, manual measurement can lead to significant measurement errors due to operational uncertainty. Furthermore, residual material inevitably remains within newly machined holes, which can become trapped within the holes and significantly impact measurement results.

[0003] Therefore, we propose a steel structure steel beam hole inspection device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 3 , including a workbench 1 and a U-shaped support rod 11 fixedly installed on the upper end of the workbench 1, a motor 12 fixedly installed on the lower end of the U-shaped support rod 11, a telescopic cylinder 13 fixedly installed on the output end of the motor 12, a mounting plate 14 fixedly installed on the side wall of the U-shaped support rod 11, a steel beam 15 placed on the upper end of the mounting plate 14, a hole 16 is opened on the steel beam 15, a display screen 5 is fixedly installed on the side wall of the U-shaped support rod 11, and a distance measuring component 2 for measuring the distance between the two holes 16 is provided at the telescopic end of the telescopic cylinder 13. The distance component 2 includes a cross measuring caliper 21 fixedly mounted on the telescopic end of the telescopic cylinder 13, and four telescopic rods 22 are fixedly mounted on the side wall of the cross measuring caliper 21. The four telescopic rods 22 are each provided with a circular limiting hole 24, and the telescopic ends of the four telescopic rods 22 are each provided with a plurality of mounting grooves 25. Circular blocks 26 are slidably mounted in the plurality of mounting grooves 25, and a spring 23 is provided between the circular block 26 and the mounting groove 25. A cleaning component 3 for cleaning the remaining residue in the hole 16 is provided on the side wall of the telescopic rod 22.

[0021] The cleaning assembly 3 includes a support sleeve 31 fixedly mounted on the telescopic end of the telescopic rod 22, a fixing groove 32 is provided on the support sleeve 31, a support rod 33 is slidably mounted on the fixing groove 32, two springs 34 are arranged between the support rod 33 and the fixing groove 32, a cylinder 35 is fixedly mounted on the inner wall of the support sleeve 31, and two semicircular rubber blocks 36 are fixedly mounted on the ends of the cylinder 35. The semicircular rubber blocks 36 have good adsorption and expansion properties. When the semicircular rubber blocks 36 leave the support sleeve 31, the semicircular rubber blocks 36 will expand to both sides. A hole measuring assembly 4 for measuring the aperture is provided in the support sleeve 31.

[0022] The size of the support rod 33 is larger than the hole 16 on the steel beam 15, so that the support rod 33 will fall on the steel beam 15, and the steel beam 15 will squeeze the support rod 33, causing the support rod 33 to shrink.

[0023] In this embodiment: first, the steel beam 15 is placed on the mounting plate 14, and the circular block 26 is squeezed to squeeze the spring 1 23, thereby adjusting the length of the telescopic end of the telescopic rod 22, and then the scale on the cross measuring caliper 21 is observed to calculate and verify the spacing between the two holes 16. After the spacing is verified, the lengths of the four telescopic rods 22 are all adjusted to the verified size. Through this operation, the spacing between the two holes 16 can be verified to ensure that the spacing between the two holes 16 meets the requirements. At this time, the telescopic cylinder 13 is started to make the telescopic cylinder 1 The telescopic end of 3 drives the cross measuring caliper 21 to move downward, thereby causing the telescopic rod 22 to drive the support sleeve 31 to move downward. When the support rod 33 contacts the steel beam 15 and then moves downward, the steel beam 15 will squeeze the support rod 33, so that the support rod 33 is squeezed into the fixing groove 32 by the spring 2 34. At this time, the semicircular rubber block 36 breaks away from the support sleeve 31 and enters the hole 16. The expanded semicircular rubber block 36 wipes and cleans the side wall of the hole 16, cleaning the residue in the drilling process to prevent the residue from affecting the measurement of the hole 16.

[0024] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 2 and Figure 4 The hole measuring assembly 4 includes an operating column 41 fixedly installed on the inner wall of the supporting sleeve 31. Two limiting grooves 42 are provided on the operating column 41. Laser diameter gauges 43 are slidably installed on the two limiting grooves 42. The model of the laser diameter gauge 43 is CDM25A. A spring 44 is arranged between the laser diameter gauge 43 and the limiting groove 42.

[0025] The two limiting grooves 42 are on the same horizontal plane, and the distance between the two limiting grooves 42 is known. The diameter of the hole 16 can be accurately transmitted to the display screen 5 through the laser caliper 43 .

[0026] The head of the laser caliper 43 is arc-shaped. After the detection is completed, due to the arc-shaped head, the laser caliper 43 can smoothly enter the limiting groove 42 through the spring three 44 when the operating column 41 moves upward.

[0027] In this embodiment: the telescopic cylinder 13 is displaced upward, causing the cleaning assembly 3 to leave the hole 16, and the motor 12 is started to rotate the cross measuring caliper 21 90 degrees. At this time, the hole measuring assembly 4 is located directly above the hole 16, causing the telescopic cylinder 13 to be displaced downward, driving the support sleeve 31 to move downward, and the steel beam 15 will squeeze the support rod 33, so that the support rod 33 is squeezed into the fixing groove 32 through the spring two 34. At this time, the operating column 41 is separated from the support sleeve 31, and the laser caliper 43 contacts the inner diameter of the hole 16 through the spring three 44, and the data on the laser caliper 43 is transmitted to the display screen 5, thereby inspecting the inner diameter of the hole 16.
