Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a positioning device for the installation of a straight-angle steel tower foundation. Background Technology

[0002] In the construction of power transmission, communication base stations and other projects, straight angle steel towers have become widely used infrastructure due to their advantages such as structural stability and strong load-bearing capacity. The installation and positioning of the foundation of straight angle steel towers is a key link to ensure the stability and safety of the tower body. Its accuracy and efficiency directly affect the project quality and construction progress.

[0003] Traditional straight angle steel tower foundation installation and positioning mainly rely on bolt connections for fixing. This method has many problems in actual operation. On the one hand, there is no auxiliary equipment for positioning during the bolt connection installation process, so a large number of bolts need to be tightened one by one, which is cumbersome and time-consuming. Especially in large-scale construction scenarios, it seriously affects construction efficiency. On the other hand, because the tightness of the bolts is difficult to control precisely, it is easy to cause positioning deviation of the angle steel tower foundation, making it difficult to achieve high-precision installation, and thus affecting the stability and safety of the tower.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figure 1-6 This utility model provides a technical solution: a positioning device for the installation of a straight-angle steel tower foundation, comprising:

[0026] The tower body 1 has a fixing device 2 welded to its outer wall. The inner wall of the fixing device 2 is threaded with an auxiliary device 3. The auxiliary device 3 fixes the tower body 1 by sliding, welding the tower body 1 and the fixing device 2 together. Then, the auxiliary device 3 fixes and quickly positions the tower body 1 together.

[0027] The fixing device 2 includes a positioning frame 20, the bottom end of which contacts a base 21. A limiting groove 22 is formed on the inner wall of the base 21, and the limiting grooves 22 are arranged in a circumferential array along the central axis of the base 21. A sliding groove 23 is symmetrically formed on the inner wall of the limiting groove 22, and the inner wall of the sliding groove 23 is slidably connected to the auxiliary device 3. The inner wall of the positioning frame 20 is welded to the outer wall of the tower body 1, and the sliding groove 23 is formed on the inner wall of the base 21. First, the positioning frame 20 is welded to the outer wall of the tower body 1 to ensure a firm connection. Then, the positioning frame 20 is placed on the base. On 21, they are brought into contact with each other. During the positioning process of the fixing device 2, the rotating rod 30 in the auxiliary device 3 is rotatably connected to the inner wall of the positioning frame 20 and the base 21, and the bottom end is fixedly connected to the cam 32. The cam 32 restricts the rotating rod 30 to the inner wall of the base 21, and the threaded groove 31 area at its top end is slidably connected to the inner wall of the positioning frame 20. During the process of the positioning frame 20 and the base 21 in contact, the positioning frame 20 can be positioned through the threaded groove 31 area at the top end of the rotating rod 30. After the positioning frame 20 is initially positioned, the subsequent installation can be carried out.

[0028] The auxiliary device 3 includes a rotating rod 30, the outer wall of which is provided with a threaded groove 31. A cam 32 is fixedly connected to the bottom end of the rotating rod 30. The outer wall of the rotating rod 30 is symmetrically and rotatably connected to the inner wall of the positioning frame 20 and the base 21. The outer wall of the threaded groove 31 is fixedly connected to the outer wall of the positioning frame 20 through a nut, and the outer wall of the nut contacts the outer wall of the positioning frame 20. The outer wall of the cam 32 is rotatably connected to the inner wall of the limiting groove 22. When it is necessary to install and position the tower body 1, the bolt 35 is placed in the inner wall of the base 21 and the positioning frame 20, and then the rotating rod 30 is rotated. The rotation of the rotating rod 30 will drive the cam 32 to rotate in the limiting groove 22. Since the outer wall of the cam 32 is symmetrically and slidably connected with a locking block 33, and the outer wall of the locking block 33 is slidably connected to the inner wall of the sliding groove 23.

[0029] A locking block 33 is symmetrically slidably connected to the outer wall of the cam 32. An I-beam 34 is slidably connected to the outer wall of the locking block 33. A bolt 35 is fixedly connected to the top of the I-beam 34. The outer wall of the locking block 33 is slidably connected to the inner wall of the sliding groove 23. The outer wall of the I-beam 34 is slidably connected to the inner wall of the positioning frame 20 and the base 21. The outer wall of the bolt 35 is threadedly connected to the inner wall of the positioning frame 20 and the base 21. As the cam 32 rotates, its contour shape will push the locking block 33 to slide in the sliding groove 23. Since the top of the I-beam 34 is fixedly connected to the bolt 35, when the outer wall of the locking block 33 matches the outer wall of the I-beam 34, the movement of the bolt 35 can be restricted, and the tower body 1 can be accurately positioned. Then, the nut is threaded along the outer wall of the threaded groove 31 to contact the outer wall of the positioning frame 20 until the nut stops rotating, so that the positioning frame 20 and the base 21 are further reinforced.

[0030] In use, the tower body 1 is welded together with the fixing device 2, and then fixed and quickly positioned together by the auxiliary device 3;

[0031] First, weld the positioning frame 20 to the outer wall of the tower body 1 to ensure a firm connection between the two. Then, place the positioning frame 20 on the base 21 so that they are in contact with each other.

[0032] During the positioning process of the fixing device 2, the rotating rod 30 in the auxiliary device 3 is rotatably connected to the inner wall of the positioning frame 20 and the base 21, and the bottom end is fixedly connected to the cam 32. The cam 32 restricts the rotating rod 30 to the inner wall of the base 21, and the threaded groove 31 area at its top end is slidably connected to the inner wall of the positioning frame 20. During the process of the positioning frame 20 and the base 21 in contact, the positioning frame 20 can be positioned through the threaded groove 31 area at the top end of the rotating rod 30. After the positioning frame 20 is initially positioned, the subsequent installation can be carried out.

[0033] When it is necessary to install and position the tower body 1, place the bolt 35 in the inner wall of the base 21 and the positioning frame 20, and then rotate the rotating rod 30. The rotation of the rotating rod 30 will drive the cam 32 to rotate in the limiting groove 22. Since the outer wall of the cam 32 is symmetrically slidably connected with the locking block 33, and the outer wall of the locking block 33 is slidably connected with the inner wall of the sliding groove 23.

[0034] As the cam 32 rotates, its contour shape pushes the locking block 33 to slide in the sliding groove 23. Since the top of the I-beam 34 is fixedly connected to the bolt 35, when the outer wall of the locking block 33 matches the outer wall of the I-beam 34, the movement of the bolt 35 can be restricted, thus achieving precise positioning of the tower body 1. Then, the nut is threaded along the outer wall of the threaded groove 31 to contact the outer wall of the positioning frame 20 until the nut stops rotating, further reinforcing the positioning frame 20 and the base 21.
