[0026] The following is combined with the attached Figure 1 - attachedFigure 3 A further detailed description of the present utility model will be given below.

[0027] An embodiment of the present utility model discloses a device for installing anchor bolts of equipment. Referring to Figure 1 , the device for installing anchor bolts of equipment is used to finely adjust the position of the anchor bolt 1 after the anchor bolt 1 is pre-buried. The upper part of the anchor bolt 1 is wrapped with adhesive tape. The installation device includes a corrugated pipe 2, which is a steel corrugated pipe. It is pre-buried in the concrete of the primary structural layer and its top protrudes 20 mm above the elevation of the primary structural surface. The corrugated pipe 2 is sleeved outside the rod part of the anchor bolt 1 and is coaxially arranged with the anchor bolt 1. An adjustment hole 20 is formed in the corrugated pipe 2, and the adjustment hole 20 provides an operating space for adjusting the positioning of the anchor bolt 1 before equipment installation.

[0028] Referring to Figure 1 and Figure 2 , a steel upper cover 3 is threadedly installed at the top of the corrugated pipe 2. The upper cover 3 is used to prevent concrete from entering the corrugated pipe 2 during concrete pouring due to improper operation, resulting in blockage of the adjustment hole 20. A steel lower cover 4 is threadedly installed at the bottom of the corrugated pipe 2. The lower cover 4 is used to prevent concrete from entering the corrugated pipe 2 due to the gravity of the height difference of the concrete itself during concrete pouring, resulting in blockage of the adjustment hole 20. Holes for the anchor bolt 1 to pass through are respectively formed at the central positions of the upper cover 3 and the lower cover 4.

[0029] Referring to Figure 3 , the corrugated pipe 2 is matched with a split ultra-thin jack 5. When it is necessary to adjust the anchor bolt 1, the construction worker first removes the upper cover 3, heats the root of the anchor bolt 1 with a flame heater, and then uses the split ultra-thin jack 5 in the adjustment hole 20 to adjust the position of the anchor bolt 1 from the root, so as to ensure that the equipment hole can be accurately installed on the anchor bolt 1 and improve the construction efficiency.

[0030] Referring to Figure 1 , a secondary grouting layer 6 with a thickness of 50 mm is constructed on the top of the primary structural layer. The secondary grouting layer 6 completely covers the corrugated pipe 2, and the adjustment hole 20 of the corrugated pipe 2 is simultaneously filled with slurry to fix the anchor bolt 1. An equipment base 7 is placed on the top of the secondary grouting layer 6. The equipment base 7 is installed on the anchor bolt 1, and then the gasket 8 and the nut 9 are installed on the top of the anchor bolt 1 to fix the equipment base 7.

[0031] The implementation principle of the equipment anchor bolt installation device in the embodiment of the present utility model is as follows: The construction workers first embed the anchor bolt 1 and the corrugated pipe 2 with the upper cover 3 and the lower cover 4 into the concrete of the primary structure layer. If the position of the anchor bolt 1 needs to be adjusted, the construction worker removes the upper cover 3, heats the root of the anchor bolt 1 with a flame, and uses the separating ultra-thin jack 5 to push the anchor bolt 1 to achieve the purpose of fine adjustment. Subsequently, the secondary grouting layer 6 is poured, the slurry fills the adjustment hole 20, and finally, the gasket 8 and the nut 9 are used to cooperate with the anchor bolt 1 to fix the equipment base 7.

[0032] By measuring in advance the positioning dimensions of the formed foundation anchor bolt 1 and using this device to adjust the anchor bolt 1 with construction errors, it is ensured that the equipment hole can be installed on the anchor bolt 1 at one time, reducing the construction process of re-milling the hole, ensuring the construction period, and improving the efficiency of equipment installation; The adjustable equipment anchor bolt installation device combines innovation and practicality, providing an excellent solution and is applicable to the construction of large equipment foundation bolt groups in the engineering field.

[0033] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
