Description

Technical Field

[0001] This invention relates to the field of correction clamp technology, and more particularly to correction clamps for the main material of iron tower angle steel. Background Technology

[0002] Angle steel is a type of steel with a wide range of applications, serving as a primary material in structures such as communication towers, power transmission line towers, and steel trusses. Power transmission towers are mainly used to construct high-voltage transmission towers. The transmission line towers we commonly see are truss structures composed of single equilateral angle steel bars or composite angle steel bars, hence the name "angle steel towers." Angle steel towers are susceptible to slippage, tilting, settlement, and cracking under the following conditions: 1. Long-term directional swaying causing uneven stress on the tower; 2. Natural geological disasters such as earthquakes and landslides; 3. Construction around the tower; 4. Subsidence and slippage in coal mining areas. Under these natural environmental and external conditions, the foundations of power grid towers and communication towers often experience slippage, tilting, settlement, and cracking, leading to tower deformation or tilting, insufficient electrical safety distances, and affecting the normal operation of the line. Specialized clamps are needed to correct tilted towers.

[0003] Currently, the clamping structures used for correcting the tilt of iron towers are relatively simple. They involve fixing mounting plates to the tilted angle steel of the tower, and then fixing multiple mounting plates to different positions on the angle steel at varying slopes. While this method can prevent the angle steel from falling, it presents other problems in practical use. For example, it lacks an adaptive adjustment function, meaning it cannot move appropriately as the iron frame is gradually lifted and corrected after the tower is positioned, thus hindering the correction process and posing a significant safety hazard. Furthermore, it lacks a quick, no-drill assembly / disassembly function. To connect the clamps to the angle steel on the tower, bolts are drilled or temporary welding is used, which is time-consuming and labor-intensive, leaving holes at the fixing points on the tower and angle steel that require subsequent repair, thus reducing its practicality.

[0004] This invention was made to address common problems encountered in the use of clamps in this field. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of current clamps by proposing a clamp for correcting the alignment of the main material of the angle steel for iron towers.

[0006] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0007] A straightening fixture for the main material of steel tower angle steel includes a guide rail. A sliding connecting column is slidably connected through the top of the guide rail. A sliding groove for cooperating with the sliding connecting column is formed on the top of the guide rail. A connecting base plate is welded to the top of the sliding connecting column. A connecting top plate is provided on the top of the connecting base plate. Four fixed bases are equidistantly welded to the bottom of the connecting top plate. Two rotating sleeves are rotatably connected between the four fixed bases via rotating shafts. A supporting screw is welded to the bottom of the rotating sleeve. The other end of the supporting screw passes through and extends to the bottom of the connecting base plate. The connecting base plate has a limiting through hole inside for use with the support screw. The surface of the support screw and the top of the connecting base plate are threaded with a fixing nut. The bottom of the guide rail is welded with a mounting plate. A U-shaped fixing plate is welded to one side of the connecting top plate. The U-shaped fixing plate has a positioning clamping plate inside. One side of the positioning clamping plate is rotatably connected to a fixing screw through a bearing. The other end of the fixing screw passes through and extends to the outside of the U-shaped fixing plate. The surface of the U-shaped fixing plate has a threaded groove for use with the fixing screw.

[0008] Optionally, a guide block is welded to the bottom of the sliding connecting column. The volume of the guide block is larger than the volume of the sliding groove, and the shape of the guide block is rectangular.

[0009] Optionally, the guide rail is provided with a fixing baffle on both the front and back sides. The bottom of the fixing baffle is welded to the top of the mounting plate, and the height of the fixing baffle is higher than that of the guide block.

[0010] Optionally, limit guide rods are symmetrically welded to one side of the positioning clamping plate. The two limit guide rods are located on the front and back of the fixing screw, respectively, and the other end of the limit guide rods passes through and extends to the outside of the U-shaped fixing plate.

[0011] Optionally, a fixing handle is welded to the other end of the fixing screw. The fixing handle is made of aluminum alloy and its diameter is larger than that of the fixing screw.

[0012] Optionally, the guide rail, sliding connecting column, connecting base plate, connecting top plate, fixed base, rotating sleeve, mounting fixing plate, U-shaped fixing plate and positioning clamping plate are all made of stainless steel, and the guide rail, sliding connecting column, connecting base plate, connecting top plate, fixed base, rotating sleeve, mounting fixing plate, U-shaped fixing plate and positioning clamping plate are all heat treated.

[0013] Optionally, the support screw, fixing nut, and fixing screw are all made of titanium alloy, and the surfaces of the support screw, fixing nut, and fixing screw are treated with a galvanizing process.

[0014] The beneficial effects achieved by this invention are:

[0015] 1. By welding the mounting plate to the bottom of the guide rail, if the tower angle steel is tilted left or right during installation, the U-shaped mounting plate is clamped on the front and rear sides of the tower angle steel, so that the angle steel is inside the U-shaped mounting plate. After the U-shaped mounting plate is in place, hold the fixing handle and rotate it. When the fixing handle is rotated, the fixing screw will move downward through the cooperation of the U-shaped mounting plate and the threaded groove. When the fixing screw moves inward, it will cause the bottom of the positioning clamping plate to fit tightly with the inside of the angle steel through the cooperation of the threaded groove and the limit guide rod. Then, tighten it inward with a tool. After one U-shaped mounting plate is tightened, the other U-shaped mounting plates can be installed in the same way. It has the function of quick installation and removal without drilling, simple and labor-saving operation, and can be fixed on tower angle steel of different specifications and sizes. It avoids the damage to the tower and foundation caused by frequent drilling, reduces the burden of subsequent hole repair, and has high practicality.

[0016] 2. By welding a connecting base plate to the top of the sliding connecting column, the connecting top plate, after being fixed, will tilt along with the tilt of the tower. In the tilted state, the connecting top plate, through the cooperation of the fixed base, rotating sleeve, and rotating shaft, will cause the support screw to move vertically downward a certain distance. Then, the tool will drive the fixing nut to rotate downward until the bottom of the fixing nut is in contact with the top of the connecting base plate. When the tower angle steel is corrected, it will cause the connecting top plate to tilt upward. As the angle steel changes, the connecting top plate will cause the support screw to move upward and maintain the connection with the connecting base plate. When the angle of the connecting top plate changes, its force will cause the sliding connecting column to move in the sliding groove. With the cooperation of the guide block and the sliding groove, the bottom end of the sliding connecting column can be prevented from falling off the guide rail. It has an adaptive adjustment function, so that the clamp can automatically adjust its position as the angle steel is gradually corrected, without the need for disassembly in the middle, and has high safety.

Limiting guide rods 16 are symmetrically welded to one side of the positioning clamping plate 13. The two limiting guide rods 16 are located on the front and back of the fixing screw 14, respectively. The other end of the limiting guide rod 16 passes through and extends to the outside of the U-shaped fixing plate 12. A fixing handle 17 is welded to the other end of the fixing screw 14. The fixing handle 17 is made of aluminum alloy, and its diameter is larger than that of the fixing screw 14. The guide rail 1, sliding connecting column 2, connecting base plate 4, connecting top plate 5, fixed base 6, rotating sleeve 7, mounting fixing plate 11, U-shaped fixing plate 12, and positioning clamping plate 13 are all made of stainless steel. All components are heat-treated. The support screw 8, fixing nut 10, and fixing screw 14 are made of titanium alloy, and their surfaces are galvanized.

[0026] Example 2: This example should be understood as including at least all the features of any of the foregoing examples, and further improving upon them. Specifically, it provides a straightening fixture for the main material of the angle steel of a steel tower, including a guide rail 1. A sliding connecting column 2 is slidably connected through the top of the guide rail 1. A sliding groove for cooperating with the sliding connecting column 2 is opened on the top of the guide rail 1. A connecting base plate 4 is welded to the top of the sliding connecting column 2. A connecting top plate 5 is provided on the top of the connecting base plate 4. Four fixed bases 6 are equidistantly welded to the bottom of the connecting top plate 5. Two rotating sleeves 7 are rotatably connected between the four fixed bases 6 through a rotating shaft. A supporting screw 8 is welded to the bottom of the rotating sleeve 7. The other end of the supporting screw 8 passes through and extends to the connecting base plate 4. At the bottom, the connecting base plate 4 has a limiting through hole 9 inside that mates with the support screw 8. A fixing nut 10 is threaded onto the surface of the support screw 8 and located at the top of the connecting base plate 4. A mounting fixing plate 11 is welded to the bottom of the guide rail 1. A U-shaped fixing plate 12 is welded to one side of the connecting top plate 5. A positioning clamping plate 13 is provided inside the U-shaped fixing plate 12. A fixing screw 14 is rotatably connected to one side of the positioning clamping plate 13 via a bearing. The other end of the fixing screw 14 passes through and extends to the outside of the U-shaped fixing plate 12. A threaded groove mates with the fixing screw 14 on the surface of the U-shaped fixing plate 12. Specifically, the mounting fixing plate 11 is welded to the bottom of the guide rail 1. During installation, if iron... The tower angle steel is tilted left and right. The U-shaped fixing plate 12 is then placed on the front and rear sides of the angle steel, positioning it inside the U-shaped fixing plate 12. After the U-shaped fixing plate 12 is in place, the fixing handle 17 is rotated. As the handle rotates, the fixing screw 14 moves downwards through the interaction of the U-shaped fixing plate 12 and the threaded groove. As the screw 14 moves inwards, the bottom of the positioning clamping plate 13 fits tightly against the inside of the angle steel through the interaction of the threaded groove and the limiting guide rod 16. Then, it is tightened inwards using a tool. Once one U-shaped fixing plate 12 is tightened, the remaining U-shaped fixing plates 12 are installed in the same way. This system features quick, no-drill installation and removal, is simple and labor-saving, and can be used to fix various sizes of angle steel. On small tower angle steel, frequent drilling is avoided, which can damage the tower and foundation. This reduces the burden of subsequent hole repairs and is highly practical. Simultaneously, by welding the connecting base plate 4 to the top of the sliding connecting column 2, the connecting top plate 5, after being fixed, tilts with the tower. In the tilted state, the connecting top plate 5, through the cooperation of the fixed base 6, rotating sleeve 7, and rotating shaft, causes the support screw 8 to move vertically downwards a certain distance. Then, a tool drives the fixing nut 10 to rotate downwards until the bottom of the fixing nut 10 is in contact with the top of the connecting base plate 4. When the tower angle steel is corrected, it causes the connecting top plate 5 to tilt upwards. As the angle steel changes, the connecting top plate 5 moves the support screw 8 upwards, maintaining the connection with the connecting base plate 4.When the angle of the connecting top plate 5 changes, the force it exerts causes the sliding connecting column 2 to move within the sliding groove. With the cooperation of the guide block 3 and the sliding groove, the bottom end of the sliding connecting column 2 is prevented from detaching from the guide rail 1. This provides adaptive adjustment, allowing the clamp to automatically adjust its position as the angle steel is gradually corrected, eliminating the need for disassembly midway and ensuring high safety.

[0027] A guide block 3 is welded to the bottom of the sliding connecting column 2. The volume of the guide block 3 is larger than that of the sliding groove. The guide block 3 is rectangular in shape. Specifically, by setting the guide block 3, the sliding connecting column 2 can be limited, which not only improves the smoothness of the sliding connecting column 2 sliding back and forth in the guide rail 1, but also prevents the connecting top plate 5 from moving the sliding connecting column 2 up with the sliding groove when it moves upward.

[0028] Fixed baffles 15 are provided on both the front and back of the guide rail 1. The bottom of the fixed baffle 15 is welded to the top of the mounting fixed plate 11. The height of the fixed baffle 15 is higher than that of the guide block 3. Specifically, by setting the fixed baffle 15, the guide block 3 can be limited to prevent the guide block 3 from separating from the guide rail 1 from the opening during the back and forth sliding process.

[0029] One side of the positioning clamping plate 13 is symmetrically welded with limiting guide rods 16. The two limiting guide rods 16 are located on the front and back of the fixing screw 14, respectively. The other end of the limiting guide rod 16 passes through and extends to the outside of the U-shaped fixing plate 12. Specifically, the setting of the limiting guide rod 16 can limit the positioning clamping plate 13, prevent the positioning clamping plate 13 from flipping and rotating during the up and down movement, and improve the stability of the positioning clamping plate 13 when it moves up and down.

[0030] The other end of the fixing screw 14 is welded with a fixing handle 17, which is made of aluminum alloy. The diameter of the fixing handle 17 is larger than that of the fixing screw 14. Specifically, the fixing handle 17 makes it easier for the operator to rotate the fixing screw 14.

[0031] The guide rail 1, sliding connecting column 2, connecting base plate 4, connecting top plate 5, fixed base 6, rotating sleeve 7, mounting fixing plate 11, U-shaped fixing plate 12, and positioning clamping plate 13 are all made of stainless steel. All of these components undergo heat treatment. Specifically, the guide rail 1, sliding connecting column 2, connecting base plate 4, connecting top plate 5, fixed base 6, rotating sleeve 7, mounting fixing plate 11, U-shaped fixing plate 12, and positioning clamping plate 13 have the characteristics of high strength, low density, and excellent corrosion resistance.

[0032] The support screw 8, the fixing nut 10, and the fixing screw 14 are all made of titanium alloy. The surfaces of the support screw 8, the fixing nut 10, and the fixing screw 14 are treated with galvanizing. Specifically, the support screw 8, the fixing nut 10, and the fixing screw 14 have the characteristics of high specific strength, excellent tensile strength, good plasticity, and easy processing.

[0033] In summary, the main material straightening clamp for the tower angle steel of the present invention uses a mounting plate 11 welded to the bottom of the guide rail 1. During installation, if the tower angle steel is tilted left or right, the U-shaped fixing plate 12 is clamped on the front and rear sides of the tower angle steel, so that the angle steel is inside the U-shaped fixing plate 12. After the U-shaped fixing plate 12 is in place, the fixing handle 17 is rotated by hand. When the fixing handle 17 rotates, it drives the fixing screw 14 downward through the cooperation of the U-shaped fixing plate 12 and the threaded groove. When the fixing screw 14 moves inward, it drives the bottom of the positioning clamping plate 13 to fit tightly against the inside of the angle steel through the cooperation of the threaded groove and the limiting guide rod 16. Then, it is tightened inward with a tool. After one U-shaped fixing plate 12 is tightened, the remaining U-shaped fixing plates 12 are installed in the same way. Simultaneously, by using… The connecting base plate 4 is welded to the top of the sliding connecting column 2. After being fixed, the connecting top plate 5 will tilt with the tilt of the tower. When tilted, the connecting top plate 5 will move the support screw 8 vertically downward a certain distance through the cooperation of the fixed base 6, the rotating sleeve 7 and the rotating shaft. Then, the fixing nut 10 will be rotated downward by the tool until the bottom of the fixing nut 10 is in contact with the top of the connecting base plate 4. When the tower angle steel is corrected, it will cause the connecting top plate 5 to tilt upward. As the angle steel changes, the connecting top plate 5 will cause the support screw 8 to move upward and maintain the connection with the connecting base plate 4. When the angle of the connecting top plate 5 changes, its force will cause the sliding connecting column 2 to move in the sliding groove. With the cooperation of the guide block 3 and the sliding groove, the bottom end of the sliding connecting column 2 can be prevented from falling out of the guide rail 1.
