The tower anchor bolts are important components connecting the tower and the foundation, and need to bear the weight of the tower and loads such as wind pressure. The tower anchor bolts are mainly made of four round steels welded into a square column through several connecting cross bars. Its structure is as follows Figure 7 Currently, during the tower bolt welding process, to ensure that the four round steel bars can form a square column, the steel plate needs to be cut into a square steel plate fixture that matches the anchor bolts.

DETAILED DESCRIPTION

[0028] To deepen the understanding of the present invention, the present invention will be further described below in conjunction with implementation examples and accompanying drawings. The present invention can be implemented in the following ways:

[0029] Reference Figure 1-6 , a positioning device for welding tower anchor bolts, comprising a support frame 1, a positioning plate 2 is provided on one side above the support frame 1, and the positioning plate 2 is square. The size of the positioning plate 2 in this embodiment is 520mm×520mm×8mm. At least one group of square positioning hole groups 21 is provided on the positioning plate 2, and the number of square positioning hole groups 21 in this embodiment is two groups. Each group of square positioning hole groups 21 includes an origin positioning hole 211, a row of X-axis positioning holes 212, a column of Y-axis positioning holes 213 and a row of diagonal positioning holes 214. The origin positioning hole 211 and any diagonal positioning hole 214, the X-axis positioning hole 212 and the Y-axis positioning hole 213 corresponding to the diagonal positioning hole 214 just form a square, such as Figure 4 This design can meet the needs of fixing and welding tower anchor bolts 6 of different sizes, has a wide range of applications, and saves a lot of tooling and labor costs.

[0030] Four positioning molds 3 for inserting one end of the round steel 61 of the anchor bolt 6 are detachably mounted on the square positioning hole group 21. The four positioning molds 3 are distributed in a square shape. The positioning mold 3 includes a positioning sleeve 31 for inserting one end of the round steel 61. The positioning sleeve 31 is a circular sleeve with an opening. The inner diameter of the circular sleeve is larger than the outer diameter of the round steel 61 of the anchor bolt 6, which facilitates the insertion of the end of the round steel 61 of the anchor bolt 6. The positioning sleeve 31 is provided with a bolt assembly 32 at the other end relative to the round steel 61 for detachably mounting the positioning sleeve 31 on the square positioning hole group 21. The bolt assembly 32 includes a screw 321 fixedly connected to the positioning sleeve 31 and a nut 322 adapted to the screw 321. During installation, the screw 321 of the positioning sleeve 31 is inserted into the positioning hole on the positioning plate 2, and then tightened with the nut 322. When the diameter of the round steel 61 of the anchor bolt 6 does not match the inner diameter of the positioning mold 3, it is only necessary to replace the fixed mold with a size corresponding to the round steel 61, which is easy and quick to operate.

[0031] To ensure more accurate welding of the four round steel bars 61 of the anchor bolts 6, two round steel bars 61 are provided on the other side of the support frame 1, parallel to the support bar 4 of the support frame 1, so that the anchor bolts 6 are close to the support frame 1. Limit blocks 41 are provided on both sides of the top of the support bar 4 to prevent the round steel bars 61 from falling during the welding process.

[0032] In order to ensure that the positioning plate 2 is subjected to balanced force during operation, the positioning plate 2 is provided with a plurality of supporting diagonal rods 5 on the other side of the supporting bar 4. In this embodiment, four supporting diagonal rods 5 are provided. One end of the supporting diagonal rod 5 is fixedly connected to the positioning plate 2, and the other end is fixedly connected to the support frame 1, so that a stable triangle is formed between the positioning plate 2, the support frame 1 and the supporting diagonal rods 5. When one end of the four round steel bars 61 of the anchor bolts 6 is inserted into the four positioning molds 3 of the positioning plate 2, the supporting diagonal rods 5 can prevent the positioning plate 2 from collapsing due to excessive force on one side of the round steel bars 61.

[0033] In order to make the support frame 1 more secure, the support frame 1 includes two symmetrically arranged channel steels 11, and the two channel steels 11 are fixedly connected by a plurality of connecting rods 12. A plurality of supporting feet 13 are provided at the bottom of the support frame 1. The supporting feet 13 are perpendicular to the two channel steels 11, and the two ends of the supporting feet 13 protrude outside the two channel steels 11. The cross-section of the supporting feet 13 is triangular, which can improve the stability of the support frame 1. The bottom of the positioning plate 2 is provided with a mounting groove 14 for fixing the positioning plate 2 on the top of the two channel steels 11. The mounting groove 14 is perpendicular to the two channel steels 11.

[0034] Instructions for use: According to the size of the anchor bolts 6 to be welded, insert one end of the round steel 61 with the threaded head that constitutes the tower anchor bolt 6 into the four positioning molds 3, and then weld and fix the supporting steel bars 62 on the round steel 61 according to a certain size to finalize the shape. After completing the preliminary assembly and finalization, remove it and subsequent personnel will perform most of the reinforcement welding.

[0035] When welding anchor bolts 6 of different sizes, simple adjustments are required. If only the heel opening size changes and the size of the round steel 61 remains unchanged, it is only necessary to move and adjust the three positioning dies 3 on the positioning plate 2, except for the origin positioning hole 211, to align them with the heel opening size of the anchor bolt 6. If the heel opening size of the anchor bolt 6 and the diameter of the round steel 61 are different, the four positioning dies 3 corresponding to the diameter of the round steel 61 can be replaced and installed on the positioning plate 2, and the spacing can be adjusted to align with the required heel opening.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
