[0023] This embodiment discloses a pre-embedded bolt assembly and welding device. Figure 1 The specific structure of the pre-embedded bolt assembly and welding device is shown; Figures 2 to 4 The planar structures of the first steel plate, the second steel plate, and the third steel plate involved in the pre-embedded bolt assembly and welding device are shown respectively. Figure 5 The specific structure of the adjusting bolt involved in the pre-embedded bolt assembly welding device is shown.

[0024] Please refer to Figures 1 to 5 The pre-embedded bolt assembly and welding device of this utility model includes a screw rod and a reserved thread. The device includes: a first steel plate 1, a second steel plate 2, and a fixing connector 4 for connecting the first steel plate 1 and the second steel plate 2. The first steel plate 1 and the second steel plate 2 are arranged vertically. Both the first steel plate 1 and the second steel plate 2 are provided with pre-made holes 5 that are compatible with the pre-embedded bolts. The pre-embedded bolts are positioned through the pre-made holes 5. The line connecting the pre-made holes 5 on the first steel plate 1 and the compatible pre-made holes 5 on the second steel plate 2 is perpendicular to the first steel plate 1 and the second steel plate 2. The screw rod of the pre-embedded bolt passes through the pre-made holes 5 on the second steel plate 2 and the first steel plate 1 in one go. The verticality of the pre-embedded bolt is controlled by the pre-made holes 5 distributed vertically. During construction, the opening diameter and position of the precast hole 5 are confirmed according to the requirements of the construction design drawings. The pre-embedded bolts are inserted into the precast hole 5 according to the position of the precast hole 5, which can meet the needs of construction, better control the verticality of the pre-embedded bolts, and more accurately position the pre-embedded bolts. During repeated assembly, there is no need to monitor at all times, which speeds up the assembly speed and ensures the assembly quality of the pre-embedded bolts.

[0025] Specifically, a third steel plate 3 is provided below the second steel plate 2. Both the third steel plate 3 and the second steel plate 2 have pre-drilled openings 6. Adjusting bolts 7, compatible with the pre-drilled openings 6, pass through these openings sequentially. The adjusting bolts 7 are used to adjust the distance between the second steel plate 2 and the third steel plate 3 to control the length of the pre-drilled thread. The thread length is an important parameter in mechanical design, affecting the safety and stability of the device. During the adjustment process, a measuring tape is used to measure the distance between the second steel plate 2 and the third steel plate 3 to ensure the designed pre-drilled length is met. Furthermore, a stop plate 71 is provided on the adjusting bolt 7 to effectively prevent it from falling off, thus increasing the practicality of this invention.

[0026] Furthermore, a rotating device 8 is provided on the lower end face of the third steel plate 3. The rotating device 8 is used to drive the first steel plate 1, the second steel plate 2, and the third steel plate 3 to rotate. The rotating device 8 includes: a bearing 81, a fixing rod 82 connected to the bearing 81, and a base 83. The bearing 81 is fixed at the center position of the lower end face of the third steel plate 3 and connected to one end of the fixing rod 82. The other end of the fixing rod 82 is fixed to the base 83 by welding. Alternatively, the bearing 81 is fixed at the center position of the base 83 and connected to one end of the fixing rod 82. The other end of the fixing rod 82 is fixed to the center position of the lower end face of the third steel plate 3 by welding. When assembling the embedded bolts, the bearing 81 rotates the third steel plate 3, which in turn drives the second steel plate 2 to rotate. The rotation of the second steel plate 2 drives the first steel plate 1 to rotate. By rotating the first steel plate 1, it is convenient for construction personnel to weld the embedded bolts at different positions, effectively avoiding the welding difficulties caused by limited operating space.

[0027] In this embodiment, the fixing connector 4 is made of round steel, the thickness of the first steel plate 1 is 6mm, and the thickness of the second steel plate 2 and the third steel plate 3 is 10mm. The fixing connector 4 is perpendicular to the first steel plate 1 and the second steel plate 2, and is welded to the middle of each side of the first steel plate 1 and the second steel plate 2; while the reserved openings 6 are evenly distributed at each corner of the second steel plate 2 and the third steel plate 3. In this embodiment, the first steel plate 1, the second steel plate 2, and the third steel plate 3 are all square. By placing the fixing connector 4 at the middle of each side and placing the reserved openings 6 at each corner, the stability of the device can be enhanced, which is beneficial to the normal progress of construction.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
