Description

Technical Field

[0001] This invention relates to the field of steel strand processing, and in particular to a wire feeding device for processing prestressed steel strands. Background Technology

[0002] Steel strand is a high-strength flexible steel material made by twisting multiple high-strength, high-carbon steel wires together and undergoing stress-relieving and stabilizing treatment. Its core purpose is for prestressed tensioning and load-bearing. Steel strand processing requires wire laying, which involves the use of wire laying devices.

[0003] The existing technology patent number CN111137744A discloses a constant tension wire feeding frame, which adopts a magnetic powder tension control design. By setting a voltage to the magnetic powder tension control device, the magnetic powder meshes with the gear to drive the wire feeding roller. The tension will not change without human intervention, and the wire feeding tension is kept constant, which solves the problem of the wavy appearance of the product caused by the unstable tension of the traditional wire feeding frame.

[0004] However, before actual wire feeding, due to the large size and heavy weight of the wire feeding roller, it is quite laborious to move the wire feeding roller on the wire feeding frame for installation or removal by manual operation, which also reduces work efficiency. Therefore, there are areas for improvement. Summary of the Invention

[0056] See Figures 1-3 The lifting structure includes: a fixed plate 8 fixedly sleeved on the bracket 4; a motor 5 mounted on the support frame 1; a screw 6 connected to the top of the output shaft of the motor 5; and a lifting plate 7 movably sleeved on the bracket 4. The lifting plate 7 has a threaded groove for the screw 6 to pass through. An L-shaped plate 9 is connected to the middle of one side of the lifting plate 7, and a lifting plate 10 is mounted on the top of the L-shaped plate 9. The guiding structure includes: two guide plates 11 connected to the front of the connecting plate 2; an inclined guide portion is provided at the front end of the guide plate 11; the connecting plate 2 and the guide plates 11 together form a guide frame; and a supporting and tightening structure. The structure includes: a vertical plate 23 fixedly sleeved on a bracket 4; a rotating column 42 rotatably passes through the left vertical plate 23; one end of the rotating column 42 is fixedly connected to a first support column 14; a first abutment plate 12 is fixedly sleeved on the first support column 14; a turntable 13 rotatably passes through the right vertical plate 23; a rotating cylinder 16 is connected to one side of the turntable 13; a movable column 17 is movably inserted into the rotating cylinder 16; one end of the movable column 17 is fixedly connected to a second support column 19; a second abutment plate 18 is fixedly sleeved on the second support column 19; an electric push rod 15 is installed on the turntable 13; one end of the output shaft of the electric push rod 15 is connected to the movable column 17.

[0057] The drive structure includes: a mounting plate 20 fastened to the left vertical plate 23 by bolts; a magnetic powder tension control device 21 is installed on the mounting plate 20; a controller 22 is installed on the side of the mounting plate 20; and two second gears that mesh with each other are sleeved on the rotating shaft connected to the output end of the magnetic powder tension control device 21 and the rotating column 42.

[0058] Guided by the two guide plates 11, the wire feeding roller 3 is pushed between the two guide plates 11 on the ground, and the connecting plate 2 limits the wire feeding roller 3. At this time, the wire feeding roller 3 is in the lifting position. Then, the motor 5 on the support frame 1 drives the screw 6 to rotate. The lifting plate 7 moves upward on the rotating screw 6, driving the lifting plate 10 at one end of the L-shaped plate 9 to move upward and lift it to both ends of the wire feeding roller 3. As the lifting plate 7 continues to move, the wire feeding roller 3 automatically moves upward to the wire feeding position. Then, the screw 6 stops, and the electric push rod 15 is started to drive the moving column 17 in the rotating drum 16. The moving column 17 drives the second support column 19 to insert into the wire feeding roller 3. The second abutment plate 18 on the moving column 17 moves and presses against the wire feeding roller 3. As the moving column 17 continues to move, the second abutment plate 18 pushes the wire feeding roller 3 to move on the lifting plate 10 and fit onto the first support column 14. The other end of the wire feeding roller 3 presses against the first abutment plate 12. Finally, the magnetic powder tension control device 21 drives the rotating column 42 to rotate. The static friction generated between the first abutment plate 12, the wire feeding roller 3 and the second abutment plate 18 drives the wire feeding roller 3 to rotate, thus performing automatic wire feeding.

[0059] See Figures 4-6 The lifting and moving structure includes: a fixed frame 25 set on the front and rear sides of the support frame 1, with guide grooves 27 on both inner walls of the fixed frame 25, guide blocks 26 slidably set in the guide grooves 27, and a through plate 28 connected between each group of two guide blocks 26, the through plate 28 movably passing through the fixed frame 25; a through groove 29 for the through plate 28 to be inserted into the support frame 1, two protrusions 30 set below the through plate 28, and rollers 31 installed on the protrusions 30; the driving structure includes: a fixed block 32 connected to the support frame 1, a hydraulic cylinder 33 installed on the fixed block 32, a through rod 34 installed at one end of the output shaft of the hydraulic cylinder 33, an extrusion groove 35 opened on the through plate 28, and one end of the through rod 34 movably passing through the extrusion groove 35; the tilting support structure includes: a tilting rod 36 rotatably passing through the bracket 4 near the bottom end, with rotating handles 37 fixedly sleeved near both ends of the tilting rod 36, and a support plate 38 installed at one end of each group of two rotating handles 37; the transmission structure includes:

[0060] A first gear 41 is fixedly sleeved on both ends of the flipping rod 36; a sleeve plate 39 is fixedly sleeved on both ends of the through rod 34, and a moving bar 40 is connected to the top of the sleeve plate 39. The moving bar 40 is provided with teeth that mesh with the first gear 41. When the wire feeding frame is moved to the wire feeding position by the rolling of the roller 31, the hydraulic cylinder 33 on the fixed block 32 is activated, which drives the through rod 34 to move in the extrusion groove 35. By the extrusion of one end of the through rod 34 against the groove wall of the extrusion groove 35, the through plate 28 is pushed up on the fixed frame 25. When the roller 31 is gradually disengaged, the support frame 1 is smoothly supported on the ground. At the same time, the movement of the through rod 34 drives the sleeve plate 39 and the moving bar 40 to move as a whole. The first gear 41 drives the flipping rod 36 and the rotating handle 37 to rotate. The rotating handle 37 drives the support plate 38 to flip and support on the ground, increasing the support area of ​​the wire feeding frame on the ground and improving the support stability during wire feeding.

[0061] The implementation principle of a wire feeding device for prestressed steel strand processing according to an embodiment of the present invention is as follows: First, when the device is moved to the wire feeding position by the rolling of the roller 31, the hydraulic cylinder 33 on the fixed block 32 is activated, which drives the through rod 34 to move in the extrusion groove 35. By using the extrusion of one end of the through rod 34 against the groove wall of the extrusion groove 35, the through plate 28 is pushed upward on the fixed frame 25. When the roller 31 is gradually disengaged, the support frame 1 is smoothly supported on the ground. At the same time, the movement of the through rod 34 drives the sleeve plate 39 and the moving bar 40 to move as a whole. The first gear 41 drives the flipping rod 36 and the rotating handle 37 to rotate. The rotating handle 37 drives the support plate 38 to flip and support on the ground, increasing the support area of ​​the wire feeding frame on the ground and improving the support stability during wire feeding. Then, under the guidance of the two guide plates 11, the wire feeding roller 3 is pushed between the two guide plates 11 on the ground, and the connecting plate 2 limits the wire feeding roller 3. At this time, the wire feeding roller... 3. When in the lifting position, the motor 5 on the support frame 1 drives the screw 6 to rotate. The lifting plate 7 moves upward on the rotating screw 6, causing the lifting plate 10 at one end of the L-shaped plate 9 to move upward and lift it to both ends of the wire feeding roller 3. As the lifting plate 7 continues to move, the wire feeding roller 3 automatically moves upward to the wire feeding position. Then, the screw 6 stops, and the electric push rod 15 is activated to drive the moving column 17 to move in the rotating drum 16. The moving column 17 drives the second support column 19 to insert into the wire feeding roller 3. The second abutment plate 18 moves and presses against the wire feeding roller 3. As the moving column 17 continues to move, the second abutment plate 18 pushes the wire feeding roller 3 to move on the lifting plate 10 and onto the first support column 14. The other end of the wire feeding roller 3 presses against the first abutment plate 12. Finally, the magnetic powder tension control device 21 drives the rotating column 42 to rotate. The static friction generated between the first abutment plate 12, the wire feeding roller 3 and the second abutment plate 18 drives the wire feeding roller 3 to rotate, thus performing automatic wire feeding.

[0062] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
