Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt groups, in particular to an installation and fixing bracket for an iron tower pre-embedded anchor bolt group. Background Art

[0002] The pre-buried anchor bolt group of the tower is a key component in the construction of the tower foundation. It is mainly composed of multiple anchor bolts. These bolts are made of high-strength alloy steel and have excellent tensile and shear resistance. Their specifications and lengths vary according to the type, height and load factors of the tower. The anchor bolt group is distributed in an array and is pre-buried in the concrete foundation. One end has a threaded part for fastening to the connecting parts at the bottom of the tower, just like a strong root system, fixing the tower on the foundation. During installation, its position accuracy and verticality are very high to ensure that the tower can safely withstand the external force of wind load and equipment weight during long-term use.

[0003] After searching, the Chinese patent announcement number is: CN202611258U, which discloses a large-diameter anchor bolt mounting bracket, including four columns arranged in a rectangular shape, two layers of cross beams located at the upper and middle parts of each column are welded between each two columns, and the cross beams are provided with a first long bolt hole. A steel belt for fixing the anchor bolts is laid between the opposite sets of cross beams of each layer, and a second long bolt hole for connecting with the first long bolt hole through an adjustment bolt is provided at both ends of the steel belt. The utility model is simple to manufacture, light in weight, and can be made of nearby materials, and is also very convenient to adjust, which is convenient for pouring concrete. The anchor bolts are adjusted at various stages during the construction process and before pouring to ensure the installation accuracy of the anchor bolts, and a large amount of construction workload and construction costs can be saved. However, in actual use, although the anchor bolts of the above device are adjusted in parallel through steel belts to adapt to various working environments, the height of the anchor bolts cannot be adjusted, causing the angles of multiple anchor bolts to deviate. When used for large-scale connecting equipment, the installation deviation will affect the verticality of the entire device. If the verticality of the connecting device does not meet the standard, it will cause uneven force when subjected to wind force, increasing the risk of tilting and collapse of the connecting device.

During this process, due to the action of the rotating block and the restriction of the limit block, the adjusting foot will not rotate but will only move up and down in the vertical direction. By adjusting the rotating rods at the four corners separately, the horizontal angle of the fixed bracket can be accurately adjusted before pouring concrete, allowing the fixed bracket to adapt to different installation site conditions.

[0030] 2. In the utility model, the bidirectional threaded tube is rotatably connected to the top of the fixing rod, and the top of its inner wall is rotatably connected to the bolt rod. By rotating the bidirectional threaded tube, the fixing rod and the bolt rod move relative to each other due to the bidirectional thread structure of the inner wall, so that the bolt rod can be extended and retracted.

[0044] Specifically, the top of the adjusting foot 4 is adapted to the guide hole 3, the adjusting foot 4 can slide on the inner wall of the guide hole 3 and will not fall off the guide hole 3, the rotating block 18 is connected between the adjusting foot 4 and the rotating rod 7, and its outer wall is consistent with the inner wall of the threaded block 6. The function of the two-way threaded tube 201 is to connect and control the bolt rod 202 and the fixing rod 9. The threaded groove 12 opened on the top of the bolt rod 202 is used to connect the fixing nut 13. When the fixing nut 13 is installed on the top, the fixing function with the iron tower can be realized. After the device is installed, the connecting block 11 on the outer wall of the bolt rod 202 is in a position horizontal to the ground, and the fixing nut 13 is used to firmly fix the top of the bolt rod 202 and the connection with the iron tower to ensure the stability of the entire device and the firmness of the connection.

[0045] Reference Figure 1 、 Figure 4 and Figure 5 A spring washer 14 is provided at the bottom of the fixing nut 13, and the bottom of the spring washer 14 fits with the top of the connecting block 11.

[0047] Working principle: The guide holes 3 at the four corners of the fixed base plate 1 provide sliding space for the adjusting foot 4, and the adjusting foot 4 can slide up and down on the inner wall of the guide hole 3, and the multiple limit blocks 5 on the top of the outer wall of the adjusting foot 4 can prevent the adjusting foot 4 from slipping out of the guide hole 3 during the up and down sliding process, and limit the rotation of the adjusting foot 4, so that the movement trajectory of the adjusting foot 4 is limited to the vertical direction. The threaded blocks 6 at the four corners of the top of the fixed base plate 1 are connected to the rotating rod 7 through threads. When the rotating rod 7 rotates, due to the action of the threads, the rotating rod 7 can move up and down on the inner wall of the threaded block 6. The force-bearing rod 8 on the top of the rotating rod 7 facilitates the construction workers to apply the rotational torque. The rotating rod 7 is connected to the bottom of the rotating rod 7. The moving block 18 is connected to the adjusting foot 4, so that the rotational movement of the rotating rod 7 can be converted into the up and down linear movement of the adjusting foot 4, and in this process, due to the action of the rotating block 18 and the restriction of the limit block 5, the adjusting foot 4 will not rotate, but will only move up and down in the vertical direction. By adjusting the rotating rods 7 at the four corners respectively, the horizontal position of the fixed bracket can be accurately changed to adapt to different installation site conditions. The multiple fixing rods 9 connected to the top of the outer wall of the fixed base plate 1 and the reinforcement arms 10 fixedly connected to the outer walls of the fixing rods 9, the reinforcement arms 10 connect the various fixing rods 9 into a whole, so that the fixing rods 9 can remain stable when subjected to external forces and will not be easily deformed or damaged;

When a rotational force is applied to the two-way threaded tube 201, due to the two-way thread structure of its inner wall, the fixing rod 9 and the bolt rod 202 located at the upper and lower ends of the inner wall of the two-way threaded tube 201 will produce relative movement, that is, away from and close to each other, thereby realizing the telescopic function of the bolt rod 202. The multiple sliding grooves 205 opened in the middle of the outer wall of the bolt rod 202 cooperate with the sliding frame 204 to limit the sliding frame 204. When the bolt rod 202 moves up and down, due to the two-way threaded structure opened at the four corners of the sliding frame 204 The circular hole is slidably connected to the slide groove 205, so the sliding frame 204 can slide up and down in the slide groove 205 without detaching from the outer wall of the bolt rod 202, so that the bolt rod 202 will not be hindered by the sliding frame 204 during the up and down movement, thereby ensuring the flexibility of the telescopic action. At the same time, the sliding frame 204 not only does not interfere with the telescopic movement of the bolt rod 202, but also enhances the connection stability between multiple bolt rods 202. During the telescopic process, the sliding frame 204 connects each bolt rod 202 together, so that the telescopic action of the bolt rod 202 is stable. When installing the fixed bracket, the height of the bolt rod 202 can be adjusted according to the construction situation to adapt to more usage scenarios.
