[0002] It is known that in the construction of power plants, there are more and more track-type equipment foundations. With the improvement of the level of equipment automation, track installation has higher requirements on the accuracy of the pre-embedded positioning of U-bolts on the foundation, so the accuracy of the pre-embedded positioning of U-bolts is closely related to the precise installation of the track. At present, the tracks of most equipment foundations are fixed by pre-embedded U-bolts, and the pre-embedded U-bolts need to be cast in the concrete foundation. Among them, the conventional construction practice is to position each U-bolt separately by hanging wires, hanging plumbs, etc.

[0003] However, in actual use, since the embedded positioning and fixation of the U-bolts are carried out on the already tied foundation steel bars, it is inconvenient to adjust the embedded size of the U-bolts, which is easy to change, resulting in large errors; and during the construction process, especially during the concrete pouring process, the pouring and vibration of the concrete disturb the steel bars, which can easily cause the installed U-bolts to move with the steel bars, thereby changing their position and affecting the accuracy of the actual installation.

[0004] Therefore, in order to solve the problems of: limited by operating conditions and process, cumbersome and repetitive positioning process of embedded bolts, low operating efficiency, large amount of manpower and material resources required, and difficulty in ensuring the position accuracy of embedded bolts during installation, which affects the installation of equipment tracks, a U-bolt embedded fixing device for power equipment tracks is proposed as a further improvement, so that the U-bolt embedded installation operation is simple and the positioning is accurate.

[0044] The length of the first rectangular frame 11 is smaller than that of the second rectangular frame 21 , and the width of the first rectangular frame 11 is the same as that of the second rectangular frame 21 .

[0045] Among them, since the power equipment track is divided into multiple sections, the utility model can not only perform positioning correction in a single section, but also perform positioning correction on the embedded U-bolts across sections; and after the embedded U-bolts are installed and positioned, the first adjustment bracket 1 and the second adjustment bracket 2 are used as references to fix the U-bolts in the adjustment section to maintain the straightness and spacing between the multiple U-bolts; the details are as follows:

[0046] Since the first oblong through hole 13 and the second oblong through hole 23 are provided with scale lines in the length direction, the spacing between the U-shaped bolts can be accurately adjusted; and the first oblong through hole 13 provided on the first adjustment bracket 1 can be used to position and correct the three groups of pre-embedded U-shaped bolts; and the second oblong through hole 23 provided on the second adjustment bracket 2 can also position and correct the three groups of pre-embedded U-shaped bolts; and the scale of the tape measure 31 of the telescopic device 3 is used to position and correct the pre-embedded U-shaped bolts covered by the tape measure 31;

[0076] In a preferred embodiment, as shown in the attached Figure 1-3 As shown, the distance between the two mutually parallel first oblong through holes 13 and the distance between the two mutually parallel second oblong through holes 23 are equal, so that both ends of a plurality of U-shaped bolts can enter the first oblong through holes 13 and the second oblong through holes 23 unimpeded.

[0077] Working principle of this utility model:

[0078] When in use, if positioning correction is required on a separate section, three sets of U-shaped bolts in the section pass through the first oblong through holes 13 on the first adjustment bracket 1, and the height to be exposed of the U-shaped bolts is adjusted by the limit plate 4;

[0079] Then, the scale on the first oblong through hole 13 is used to ensure the accuracy of the spacing between the U-shaped bolts; the position of the extension rod 5 is freely adjusted by the bolts, and the whole is fixed after the extended height of the embedded U-shaped bolts meets the design requirement value; then, the tape measure 31 is stretched so that multiple U-shaped bolts enter the area divided by the tape measure 31;

[0080] Then, three sets of U-shaped bolts are passed through the second oblong through hole 23 on the second adjustment bracket 2, and the height of the U-shaped bolts to be exposed is still adjusted by the limit plate 4; then, the scale on the second oblong through hole 23 is used to ensure the accuracy of the spacing between the U-shaped bolts; the extension distance of the extension rod 5 is freely adjusted by the bolts, and the whole is fixed after the height of the pre-embedded U-shaped bolts meets the required design value;

[0081] Subsequently, the multiple embedded U-bolts covered by the tape measure 31 are positioned and corrected, that is, the spacing is adjusted and fixed according to the scale on the tape measure 31; at the same time, the influence of the dumping and vibration of concrete on the disturbance of the U-bolts during the concrete pouring process can be monitored, and after the concrete pouring is completed, the U-bolt embedded fixing device can be removed and recycled to the next separate equipment track section for positioning and correcting the U-bolts;

[0082] If it is necessary to position and correct the embedded U-bolts across sections, the first adjustment bracket 1 and the second adjustment bracket 2 are positioned and corrected in the two sections respectively, so that the two sections can be aligned and positioned using the tape measure 31 of the telescopic device 3, ensuring the straightness of the U-bolts of the cast foundation and the U-bolts being positioned.

[0083] The utility model is not only suitable for embedding U-bolts in power equipment tracks, but also for positioning and installing other high-precision embedded bolts. The utility model meets the embedding requirements of different types of bolts. During construction, since the track is divided into multiple sections and the U-bolts in different sections are positioned and fixed, the construction efficiency can be greatly improved, the manpower and material resources required for positioning the embedded bolts can be reduced, and the position accuracy of the embedded bolts can be easily guaranteed, the overall construction efficiency and construction quality can be improved, and the construction period can be shortened.
