Electric guide rail 2 is fixed on the side of vertical plate 12. Auxiliary lifting assembly 3 is installed on the side of the sliding block of electric guide rail 2. Detection assembly 4 is installed on the lifting end of auxiliary lifting assembly 3. Electric guide rail 2 can drive auxiliary lifting assembly 3 and detection assembly 4 to lift, and workers can realize the detection of steel structure by pushing mounting frame 1, so that workers do not need to bend for a long time or climb, reducing the labor intensity of workers. The side of the upper surface of bottom plate 11 away from electric guide rail 2 is fixed with a containing box 5. Through holes are formed in the opposite sides of containing box 5, and multiple bearing blocks 6 are contained in containing box 5. Bearing blocks 6 can balance the weight of electric guide rail 2, auxiliary lifting assembly 3 and detection assembly 4, improving the stability of mounting frame 1. Four universal wheels 13 are provided, and the four universal wheels 13 are respectively installed at the four corners of the bottom surface of bottom plate 11. The provision of universal wheels 13 facilitates the pushing of mounting frame 1 by workers.

[0032] Refer to Figure 1 And Figure 2 Auxiliary lifting assembly 3 includes first mounting plate 31, screw 32, motor 33, guide rod 34 and lifting block 35. First mounting plate 31 is a door-shaped plate, and the opening of first mounting plate 31 faces away from electric guide rail 2. The bottom end of the side of first mounting plate 31 is fixed with the sliding block of electric guide rail 2. Screw 32 is vertically arranged, and screw 32 is rotatably connected between the top surface and the bottom surface of first mounting plate 31. Motor 33 is fixed on the outer top surface of first mounting plate 31, and the output end of motor 33 is fixedly connected with screw 32. Guide rod 34 is vertically arranged, and guide rod 34 is fixed between the top surface and the bottom surface of first mounting plate 31. Lifting block 35 is threadedly connected on one side of screw 32, and slidingly connected on the other side of guide rod 34. Detection assembly 4 is installed on the side of lifting block 35. When the height of the steel structure to be detected is too high, first mounting plate 31 can extend out of electric guide rail 2, facilitating the detection of high steel structure, and when the space at the position of the steel structure to be detected is relatively low, first mounting plate 31 can be accommodated in electric guide rail 2, facilitating the detection of low space steel structure.

[0033] Refer to Figure 1 And Figure 2The detection component 4 includes a second mounting plate 41, side plates 42, hydraulic cylinders 43, a first paint thickness measuring instrument 44, limit bolts 45, a second paint thickness measuring instrument 46, and a pad 47. The second mounting plate 41 is rotatably mounted on the side of the lifting block 35 facing away from the electric guide rail 2 via a rotating shaft. Two limit holes are circumferentially formed on the side of the lifting block 35 with the axis of the rotating shaft as the center. The lines connecting the two limit holes and the axis of the rotating shaft are perpendicular to each other. The limit bolts 45 are threaded onto the mounting plate.

Inserting the limiting bolt 45 into one of the limiting holes and pushing the mounting bracket 1 allows for measurement of the two opposite sides of the vertical steel pipe. When measuring the horizontal steel pipe, rotating the second mounting plate 41 aligns the two first paint thickness measuring instruments 44 vertically.

This design minimizes the collision between the hydraulic cylinders 43 and the outer steel plate when the two hydraulic cylinders 43 are horizontally arranged, thus better protecting the hydraulic cylinders 43. When measuring the outer side of the steel plate, the second paint thickness measuring instrument 46 can be used, expanding the applicability of the device.
