[0002] The power transmission tower is referred to as the power tower. Its various tower types with structural characteristics are all space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as the tower foot are welded from several steel plates into an assembly.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , a tower foot welding positioning device of a power transmission and transformation iron tower of the present invention comprises a processing table 1, a supporting steel plate 2 and a reinforcing steel plate 3, wherein the reinforcing steel plate 3 is placed on both sides of the supporting steel plate 2, and the supporting steel plate 2 and the reinforcing steel plate 3 are both placed on the upper end of the processing table 1, two fixing components are symmetrically arranged on the processing table 1, and the reinforcing steel plate 3 is placed between the two fixing components, and the fixing component comprises two bases 5 and a first slide groove 4 which are symmetrically arranged on the left and right sides, and the supporting steel plate 2 is placed between the two bases 5, and the lower end of the base 5 is provided with a first sliding block 6 which is slidably matched with the first slide groove 4, and the lower ends of the two first sliding blocks 6 are connected by a bottom rod 7, and two fixing frames 8 are fixedly arranged at the lower end of the processing table 1, and a first rotating shaft 9 is rotatably arranged on the fixing frame 8, and two first screws 10 of positive and negative tooth structures are symmetrically arranged on the first rotating shaft 9, and the two first screws 10 respectively penetrate the two bottom rods 7, and the inner side of the base 5 is provided with a first clamping block 11 for clamping the supporting steel plate 2;

[0028] Two clamping assemblies for clamping the reinforcing steel plate 3 are symmetrically arranged at the upper end of the processing table 1, and the clamping assembly includes a support plate 15 and a clamping plate 16. The bottom end of the support plate 15 is provided with a bottom plate 23 that can slide on the processing table 1, and both ends of the bottom plate 23 are provided with limit rods 25. The clamping plate 16 is located on one side of the limit rod 25. A fixed seat 22 is fixedly arranged on one side of the clamping plate 16, and a limit plate 19 and a second clamping block 20 are arranged on the other side of the clamping plate 16. The second clamping block 20 can slide on the clamping plate 16, and a fourth screw 21 that penetrates the limit plate 19 is rotatably arranged on the second clamping block 20;

[0029] In this embodiment, the support steel plate 2 is first placed vertically on the upper end of the processing table 1, and then the first rotating shaft 9 is rotated. Through the action of the reverse thread structure, the two bottom rods 7 can slide synchronously in opposite directions along the two first screw rods 10, so that the multiple first clamping blocks 11 can clamp and fix the support steel plate 2 on the processing table 1;

[0030] Further, the reinforcing steel plate 3 is placed on both sides of the supporting steel plate 2, so that the reinforcing steel plate 3 is in vertical contact with the supporting steel plate 2, and the reinforcing steel plate 3 is placed between the second clamping block 20 and the fixing seat 22, and then the fourth screw 21 is rotated, and the second clamping block 20 can be moved through the action of the thread structure, so that the second clamping block 20 and the fixing seat 22 clamp and fix the reinforcing steel plate 3, so that the two reinforcing steel plates 3 can be vertically positioned on both sides of the supporting steel plate 2;

[0031] Since the bottom plate 23 is slidably docked with the processing table 1, pushing the support plate 15 at this time can make the support plate 15 drive the clamping plate 16 to slide, so that the clamping plate 16 can drive the reinforcing steel plate 3 to move on both sides of the support plate 15, which is convenient for temporarily adjusting the placement position of the reinforcing steel plate 3. Finally, the limit rod 25 is rotated. Since the limit rod 25 is threadedly connected to the bottom plate 23, the bottom end of the limit rod 25 can contact the processing table 1. The friction between the limit rod 25 and the processing table 1 can limit the bottom plate 23, so that the position of the support plate 15 and the clamping plate 16 can be fixed.

[0032] The position of the first clamping block 11 is not easy to adjust temporarily, which makes the present structure inconvenient to apply to support steel plates 2 of different lengths. A second slide groove 12 is provided on the inner side of the base 5, and a second slider 14 is provided at the bottom of the first clamping block 11 to slide with the second slide groove 12. A second rotating shaft 13 is arranged for rotation inside the second slide groove 12, and a second screw rod passing through the second slider 14 is arranged on the second rotating shaft 13. The second screw rod is threadedly engaged with the second slider 14, and the second rotating shaft 13 is rotated. The second slider 14 can slide in the second slide groove 12 through the threaded engagement of the second screw rod and the second slider 14, so that the first clamping block 11 can slide on one side of the base 5, which is convenient for temporarily adjusting the position of the first clamping block 11, so that the present structure can be conveniently applied to support steel plates 2 of different lengths, and has low limitations during use.

[0033] In this embodiment, a third screw 18 penetrating the support plate 15 is rotatably provided on the clamping plate 16, and a plurality of guide rods 17 penetrating the support plate 15 are provided at the four corners of the clamping plate 16. By rotating the third screw 18, the third screw 18 can be moved on the support plate 15 through the action of the threaded structure, thereby moving the position of the clamping plate 16. In this process, the plurality of guide rods 17 can improve the stability of the clamping plate 16 during movement, and the second clamping block 20 and the fixing seat 22 can be conveniently used to clamp the reinforcing steel plates 3 of different lengths, with low limitations during use.

[0034] In this embodiment, two third slide grooves 24 are symmetrically arranged at the upper end of the processing table 1, and a third sliding block slidably matched with the third slide groove 24 is arranged at the lower end of the base plate 23. When the position of the support plate 15 needs to be adjusted, the limit rod 25 is loosened to allow the base plate 23 to slide on the processing table 1. When the position of the base plate 23 is adjusted, the limit rod 25 is rotated to allow the bottom end of the limit rod 25 to be inserted into the inside of the third slide groove 24 and contact the bottom of the third slide groove 24.

[0035] In this embodiment, the cross-sections of the second slide groove 12 and the third slide groove 24 are both T-shaped, which can improve the stability of the second slider 14 and the third slider when sliding, making it difficult for the second slider 14 to disengage from the second slide groove 12 and the third slider to disengage from the third slide groove 24.

[0036] In this embodiment, the clamping surfaces of the first clamping block 11, the second clamping block 20 and the fixing seat 22 are all provided with anti-slip grooves, which can increase the friction between the first clamping block 11, the second clamping block 20 and the fixing seat 22 and the supporting steel plate 2 and the reinforcing steel plate 3.

[0037] In this embodiment, the first rotating shaft 9, the second rotating shaft 13, the fourth screw rod 21 and the third screw rod 18 are all provided with a toggle block, which can facilitate the operation of the first rotating shaft 9, the second rotating shaft 13, the fourth screw rod 21 and the third screw rod 18.
