Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0032] As Figures 1 to 4 shown, a steel bar welding device for pier construction according to an embodiment of the present invention includes a welding machine 1 and a fixed shell 2. A motion adjusting assembly for positioning during the welding of the steel bar cage is arranged inside the fixed shell 2. A rotating shell 4 is rotatably connected inside the fixed shell 2, and a fixed frame 6 is fixedly connected inside the rotating shell 4;

[0033] The adjusting assembly includes a protective shell 7. A motor 701 is fixedly connected inside the protective shell 7. The output end of the motor 701 is fixedly connected with a transmission shaft 702. A worm 703 is fixedly connected to the surface of the transmission shaft 702. A worm gear 704 is meshed with the surface of the worm 703. A rotating rod 705 is fixedly connected to one side of the worm gear 704. An adjusting disc 8 is fixedly connected to the surface of the rotating rod 705. An arc groove is formed inside the adjusting disc 8. A sliding rod 802 is slidably connected inside the adjusting disc 8. A moving plate 9 is fixedly connected to the surface of the sliding rod 802. An installation cylinder 10 is fixedly communicated with the surface of the moving plate 9.

[0034] During operation, when it is necessary to weld and form the steel bar cage used for pier construction, first, the adjusting assembly moves so that the sliding rod 802 is located at the bottom of the arc groove formed inside the adjusting disc 8, so that multiple installation cylinders 10 are concentrated near the axis of the adjusting disc 8. Then, the staff inserts the main steel bars used for welding the steel bar cage into the installation cylinders 10 that penetrate through the moving plate 9. It should be noted that when welding steel bar cages with different diameters, the insertion positions of the main steel bars will be located outside the adjusting disc 8, which can effectively save the time when the main steel bars need to be inserted into the outer circle in sequence during the production of large-diameter steel bar cages, effectively improving the welding efficiency of the steel bar cage and the construction efficiency;

[0035] It should be further noted that when welding steel reinforcement cages with different diameters, the motor 701 is started to rotate forward to drive the transmission shaft 702 to rotate. The rotation of the transmission shaft 702 drives the worm 703 to rotate forward. The rotation of the worm 703 can drive the worm wheel 704 to rotate inside the protective shell 7 through meshing transmission. The rotation of the worm wheel 704 can drive the adjustment disk 8 to rotate through the rotating rod 705. Since an arc groove is provided inside the adjustment disk 8, when the adjustment disk 8 rotates, it can drive the sliding rod 802 to move away from the axis of the adjustment disk 8 by relying on the guiding force of the arc groove. At this time, the movement of the sliding rod 802 can drive multiple groups of moving plates 9 to move. Since the installation cylinder 10 is fixedly connected to the moving plate 9, the moving plate 9 can drive multiple groups of main reinforcement bars to move outward. When the multiple groups of installation cylinders 10 drive the main reinforcement bars to move to the diameter required for the production of the steel reinforcement cage, the motor 701 is stopped at this time to stop the rotation of the adjustment disk 8 and no longer drive the multiple groups of moving plates 9 to move, which is convenient for welding steel reinforcement cages with different diameters, enables multiple main reinforcement bars to be inserted centrally, improves work efficiency, reduces the labor intensity of workers, and because the worm 703 and the worm wheel 704 itself have self-locking properties, when the worm 703 stops rotating, relying on the self-locking properties of the two, not only can the main reinforcement bars inserted into the installation cylinder 10 be smoothly adjusted in diameter, but also it can be avoided that due to the gravity of the steel bars after adjustment, the worm 703 and the worm wheel 704 are affected by gravity and affect the stability of the welding diameter of the steel reinforcement cage, which can effectively improve the stability of the steel reinforcement cage welding during pier construction, perform precise positioning work on it, have high welding quality. When the diameter of the steel reinforcement cage to be welded is determined, the welding machine 1 is started at this time to perform the steel bar welding work on the main reinforcement bars to form the steel reinforcement cage.

[0036] As Figures 4 to 5 shown, one side of the fixing frame 6 is fixedly connected with a mating disk 801. A mating groove 803 is provided inside the mating disk 801. One end of the sliding rod 802 slides inside the mating groove 803. The moving plate 9 slides inside the fixing frame 6, and the moving plate 9 is fan-shaped. One end of the rotating rod 705 is rotatably connected to the mating disk 801.

[0037] During operation, when the adjustment disk 8 rotates to drive the moving plate 9 on the surface of the sliding rod 802 to slide upward inside the fixing frame 6 to adjust the welding diameter of the steel reinforcement cage, the sliding rod 802 is limited by the arc groove provided on the surface of the adjustment disk 8 and the mating groove 803 provided on the surface of the mating disk 801 at the same time. Since the mating groove 803 is rectangularly provided inside the mating disk 801, when the sliding rod 802 moves, it will be limited by the mating groove 803 to move in a straight line, which can avoid the deviation of the position of the main reinforcement bar when it moves away from the axis position of the adjustment disk 8 due to the excessive weight of the main reinforcement bar, and can further improve the stability of the main reinforcement bar when adjusting its position;

[0038] It should be further noted that since the moving plate 9 is fan-shaped, when the moving plate 9 spreads outwards inside the fixed frame 6, the two sides of multiple moving plates 9 will gradually separate from the contact with the fixed frame 6. At this time, the frictional force generated when contacting the fixed frame 6 will be reduced, thereby reducing the moving load of the worm 703 and the worm wheel 704 and improving the moving efficiency of the moving plate 9.

[0039] As Figure 4 shown, the inside of the rotating shell 4 is configured with a matching component for cooperating with the adjusting component. The matching component includes a fixing plate 11. An inclined slot is opened inside the fixing plate 11. A connecting rod 1101 is slidably connected inside the fixing plate 11. One end of the connecting rod 1101 is fixedly connected with a pressing plate 1102. A sliding slot is opened at the position of the fixing frame 6 where the pressing plate 1102 is located, and the pressing plate 1102 slides inside the sliding slot. A groove is opened inside the moving plate 9.

[0040] During operation, when a large-diameter steel cage needs to be fabricated during pier construction, the adjusting disc 8 needs to be rotated by a large angle at this time, so that the moving plate 9 drives the main bars inside the mounting cylinder 10 to spread to a certain diameter. However, due to the increase in the diameter of the steel cage, main bars need to be added to ensure the stability after the steel cage is welded. At this time, when the moving plate 9 drives multiple main bars to perform a spreading movement through the mounting cylinder 10, the movement of the moving plate 9 will drive the fixing plate 11 to move. When the fixing plate 11 moves, it will drive the connecting rod 1101 to slide inside it through the inclined slot. At this time, the connecting rod 1101 can drive the pressing plate 1102 to slide inside the sliding slot opened in the fixing frame 6, so that the pressing plate 1102 approaches the two sides of the moving plate 9. It should be noted that when fabricating a steel cage with a small diameter, the distance that the moving plate 9 drives the mounting cylinder 10 to move outwards is small. Therefore, even when the moving plate 9 drives the fixing plate 11 to move, the moving distance is short, and it will not cause the fixing plate 11 to drive the pressing plate 1102 to move a long distance inside the fixing frame 6 through the connecting rod 1101, so that the pressing plate 1102 contacts the two sides of the moving plate 9, increasing the contact between the two, generating a frictional force on the movement of the moving plate 9, and the number of main bars is small, the load on the worm 703 and the worm wheel 704 is small. After reducing the contact between the two sides of the moving plate 9 and the inner side of the fixing frame 6 and one side of the pressing plate 1102, the stability of the main bars during welding with the stirrups can be effectively improved when welding and forming a steel cage with a small diameter;

[0041] It should be further noted that when fabricating a steel reinforcement cage with a relatively large diameter, at this time, due to the increase in the number of main reinforcement bars, when multiple groups of pressing plates 1102 approach both sides of the moving plate 9, since the number of main reinforcement bars inside the installation cylinder 10 becomes larger, the contact between the pressing plates 1102 and both sides of the moving plate 9 can ensure the stability of the moving plate 9 during its movement inside the fixing frame 6, avoiding the deviation of the moving plate 9 during the movement of the main reinforcement bars over a relatively long distance, thus affecting the diameter of the fabricated steel reinforcement cage, and the stability is relatively high;

[0042] It should be further noted that since the moving plate 9 will drive the fixing plate 11 to move a long distance inside the fixing frame 6, at this time, the greater the moving distance of the moving plate 9, the greater the gap generated between it and the fixing frame 6. When the pressing plates 1102 approach both sides of the moving plate 9, it can not only play a guiding role for the moving plate 9 to avoid deviation during movement, but also fill the gap generated between the moving plate 9 and the fixing frame 6, improving the stability of the moving plate 9 during movement.

[0043] As Figures 6 to 9 shown, a rack 1103 is fixedly connected to the lower part of the pressing plate 1102. A gear 1104 is meshed with one side of the rack 1103. A transmission rod 1105 is fixedly connected to one side of the gear 1104. A clamping plate 1106 is fixedly connected to the surface of the transmission rod 1105. A semi-circular groove is formed on the surface of the clamping plate 1106. A spring plate 1107 is slidably connected inside the clamping plate 1106. A return spring is arranged at the sliding position of the spring plate 1107 and the clamping plate 1106. An arc plate 1108 is in sliding contact with the outside of the clamping plate 1106.

[0044] During operation, when welding a steel reinforcement cage with a relatively large diameter, the extrusion plate 1102 will move inside the fixed frame 6 at this time. When the extrusion plate 1102 moves, it will drive the rack 1103 to move. The movement of the rack 1103 meshes and drives the gear 1104 to rotate. The rotation of the gear 1104 can drive the transmission rod 1105 to rotate. The rotation of the transmission rod 1105 drives the clamping plate 1106 and the spring plate 1107 inside it to rotate. It should be noted that since the extrusion plate 1102 moves a relatively large distance, the rotation angle of the clamping plate 1106 is also relatively large. And grooves are provided on both sides of the moving plate 9. When the clamping plate 1106 rotates a certain angle, one side of it will be inserted into the grooves provided on both sides of the moving plate 9. When the moving plate 9 moves again, the clamping plate 1106 will continue to rotate. And due to the provision of the grooves inside the moving plate 9, it will not affect the rotation of the clamping plate 1106. At this time, the clamping plate 1106 can continuously drive the spring plate 1107 to contact the main reinforcement inserted into the mounting cylinder 10 during the movement of the moving plate 9, so that the main reinforcement is intermittently located in the semi-circular groove provided on the surface of the clamping plate 1106, and the spring plate 1107 continuously contacts the main reinforcement. When the main reinforcement moves to the specified position, the clamping plate 1106 will not rotate again. At this time, the position of the spring plate 1107 will be perpendicular to the main reinforcement. And since multiple groups of semi-circular grooves are provided on the surface of the clamping plate 1106, when the clamping plate 1106 is perpendicular to the main reinforcement, the main reinforcement will be located in the semi-circular grooves provided on both sides, and the main reinforcement will not contact the clamping plate 1106, thereby preventing the main reinforcement from shifting during subsequent rotation and effectively improving the stability of the main reinforcement during rotational welding.

[0045] It should be further noted that when the clamping plate 1106 rotates, both sides will contact the arc plate 1108. Since the arc plate 1108 is arc-shaped, it can play a guiding role in the rotation of the clamping plate 1106, avoiding instability during the rotation of the clamping plate 1106, so that interference occurs between the clamping plate 1106 and the moving plate 9 and affects the efficiency of the diffusion movement of the moving plate 9.

[0046] As Figure 6 and Figure 9 shown, a spring column 1109 is provided between the extrusion plate 1102 and the fixed frame 6. A through groove 601 is provided inside the fixed frame 6. The extrusion plate 1102 is located outside the through groove 601. The fixing plate 11 is fixedly installed above the moving plate 9. The inclined grooves provided on the fixing plate 11 are symmetrically arranged on its surface.

[0047] During operation, when the moving plate 9 drives the main reinforcement inside the mounting cylinder 10 to adjust the distance, at this time, the fixed plate 11 moves to drive the two connecting rods 1101 to move through the two inclined slots, enabling the two pressing plates 1102 to limit the two sides of the moving plate 9. It should be noted that since the pressing plate 1102 is arranged outside the through slot 601, the length of the pressing plate 1102 at this time is not the sum of the lengths of the moving plate 9 and the fixed plate 11. Therefore, when welding a steel reinforcement cage with a smaller diameter, the pressing plate 1102 will not contact the two sides of the moving plate 9, thus causing resistance to the movement of the moving plate 9, effectively improving the smoothness of the movement of the moving plate 9 and reducing the movement load of the worm 703 and the worm gear 704. Only when welding and forming a steel reinforcement cage with a large diameter, at this time, the two pressing plates 1102 will contact the two sides of the moving plate 9 with a longer movement distance. At this time, since the worm 703 and the worm gear 704 will be affected by gravity and generate a large load themselves, the limitation of the two pressing plates 1102 will not affect them, and the steel reinforcement cage can be welded and formed effectively and quickly, with high working efficiency and stability.

[0048] As Figures 6 to 9 shown, the arc plates 1108 are arranged in a mirror image on both sides of the transmission rod 1105. The arc plates 1108 are fixedly connected in the through slot 601 opened inside the fixed frame 6. The transmission rod 1105 is rotatably connected to the fixed frame 6, and the rack 1103 is slidably connected to the fixed frame 6.

[0049] During operation, when the rack 1103 drives the gear 1104 to rotate, when welding a steel reinforcement cage with a smaller diameter, at this time, the clamping plate 1106 rotates at a smaller angle and will not intermittently insert into the groove opened inside the moving plate 9. When welding a steel reinforcement cage with a larger diameter, at this time, due to the longer movement distance of the moving plate 9, the pressing plate 1102 also moves a longer distance inside the fixed frame 6. Therefore, the clamping plate 1106 can be rotated at a larger angle, enabling the spring plate 1107 to continuously contact the main reinforcement. After the main reinforcement reaches the specified position, the spring plate 1107 will abut against the surface of the main reinforcement, and the main reinforcement will be located in the semi-circular groove opened on the surface of the clamping plate 1106 at this time, which can improve the stability of the main reinforcement during subsequent welding work.

[0050] As Figures 1 to 2 shown, a regulating seat 3 is slidably connected below the fixed shell 2. A moving component for adjusting the distance between the two fixed shells 2 is arranged inside the regulating seat 3. A limiting rod 5 is arranged between the rotating shell 4 and the mounting cylinder 10. The limiting rod 5 is made of a high-strength material.

[0051] During operation, before welding the steel reinforcement cage, first control the two fixed shells 2 to approach each other through the moving component, which facilitates the staff to insert the main reinforcement. After the main reinforcement is inserted, fix one end of the main reinforcement inside the mounting cylinder 10 on one set of fixed shells 2, and then start this set of fixed shells 2 to move away from the other set of fixed shells 2 until the welding length of the steel reinforcement cage is determined, which can facilitate the staff to operate, improve the working efficiency of welding the steel reinforcement cage, and through the setting of multiple sets of limiting rods 5, when the mounting cylinder 10 drives the main reinforcement to spread, the mounting cylinder 10 will be limited by the limiting rods 5 to maintain stability, which can further improve the stability of the main reinforcement during rotational welding, and the safety is relatively high.

[0052] As Figures 1 to 2 shown, one end of the limiting rod 5 is fixedly connected to the fixing plate 11. The limiting rods 5 are arranged at the front and rear ends of the rotating shell 4, and one end of the limiting rod 5 is slidably connected to the rotating shell 4.

[0053] During operation, when the fixing plate 11 moves along with the moving plate 9, at this time, the fixing plate 11 will drive one end of the limiting rod 5 to move outward and spread. Since the mounting cylinder 10 is fixedly connected to the moving plate 9, when welding the steel reinforcement cage, the distance between the fixing plate 11 and the mounting cylinder 10 that penetrates the inside of the moving plate 9 can always be ensured, which can effectively avoid the large centrifugal force generated by the weight of the main reinforcement itself during rotation and cause damage to the moving plate 9 and the mounting cylinder 10, and can further improve the stability of welding the main reinforcement and the stirrup.

[0054] As Figures 4 to 5 shown, the adjusting disc 8 is rotatably connected to the fixing frame 6, and both ends of the sliding rod 802 are inserted into the inside of the matching disc 801 and the adjusting disc 8 respectively.

[0055] During operation, when the adjusting disc 8 rotates to push the sliding rod 802 to move through the arc groove, since the groove opened inside the matching disc 801 has a different shape from the arc groove opened inside the adjusting disc 8, when the adjusting disc 8 rotates, the sliding rod 802 can be made to spread out parallelly. And since the adjusting disc 8 and the sliding rod 802 are respectively arranged on the front and rear sides of the fixing frame 6, when the sliding rod 802 moves, it will be subject to a uniform limiting force, and the sliding rod 802 will not be unevenly stressed during movement, which can effectively improve the stability of the movement of the moving plate 9.

[0056] As Figures 7 to 9 shown, the semi-circular groove opened on the surface of the clamping plate 1106 is larger than the diameter of the main reinforcement, and the spring plate 1107 is arranged at the position of the semi-circular groove opened on the clamping plate 1106.

[0057] During operation, when welding the main bars and stirrups of a relatively large-diameter steel reinforcement cage, the rotation of the clamping plate 1106 and the spring plate 1107 will cause the spring plate 1107 to intermittently contact the main bars, which can prevent the position of the semi-circular groove of the clamping plate 1106 from continuously contacting the main bars, thereby causing interference to the movement of the moving plate 9, improving the smoothness of the movement of the moving plate 9, and having relatively high stability.
