[0060] See attached Figure 1 To Attachment Fig.11 The steel cage welding equipment and welding method of the embodiment of the present invention will be explained in the following description, wherein the fixed assembly component 40 and the movable assembly component 50 rotate synchronously, and the movable assembly component 50 rotates while moving along the guide rail 60, so that the first tendon and the second tendon form an intersection at the welding position, and then the welding device installed on the fixed assembly component 40 is used to energize and weld the intersection, fix the first tendon and the second tendon, and weld the first tendon and the second tendon to form a steel cage, thereby improving the welding efficiency of the steel cage, and the welding device performs high-quality welding on the intersection, so that the quality of the steel cage is higher.

[0061] As attached Figure 1 and attached Figure 2 As shown, the present invention designs a steel cage welding device, comprising:

[0062] The first rib 1 assembly part is used to fix the first rib 1, including a fixed assembly component 40 and a movable assembly component 50 for the first rib 1 to pass through in sequence, and the fixed assembly component 40 and the movable assembly component 50 are respectively provided with corresponding first through holes 44 and second through holes 54;

[0063] A welding device, disposed on the fixed assembly component 40, for welding the first tendon 1 and the second tendon 2 to form a steel cage, comprising a first electrode 10 and a second electrode 20;

[0064] The guide rail 60 is used to install the mobile assembly component 50, and the mobile assembly component 50 approaches or moves away from the fixed assembly component 40 along the guide rail 60;

[0065] Among them, the fixed assembly component 40 and the movable assembly component 50 include a rotating component that drives the first tendon 1 to rotate synchronously, and the welding position 3 is the intersection 4 of the first tendon 1 and the second tendon 2; the first electrode 10, the second electrode 20 and the intersection 4 of the first tendon 1 and the second tendon 2 constitute a conductive circuit to weld and fix the second tendon 2 to the first tendon 1.

[0066] The welding device in the present invention is mainly used to weld the intersection 4 of the first tendon 1 and the second tendon 2. The first tendon 1 and the second tendon 2 are both made of metal materials. The intersection 4 of the first tendon 1 and the second tendon 2 is used as the welding position 3, and the first tendon 1 and the second tendon 2 intersect on the second electrode conductor 22, and are located between the first electrode conductor 12 and the second electrode conductor 22. The first electrode conductor 12 approaches the welding position 3 along with the first electrode moving part 11 and contacts the intersection 4. When the first electrode conductor 12 is at the welding position 3, it has a state of applying force to the intersection 4 and energizing it, and the second electrode conductor 22 is also in an energized pile. The first electrode conductor 12, the second electrode conductor 22 and the intersection 4 form a loop, and the intersection 4 is heated and softened, and is squeezed and then welded together. There are many forms of the first electrode conductor 12 applying force to the intersection 4, which are illustrated by examples below.

[0067] Embodiment 1

[0068] When welding starts, the first electrode conductor 12, driven by the first electrode moving part 11, approaches the welding position 3, and then reaches the welding position 3. At this time, the first electrode conductor 12 continues to move under the action of the first electrode moving part 11, thereby squeezing and applying force to the intersection 4. The first electrode conductor 12 is in a powered state, and forms a loop with the intersection 4 and the second electrode conductor 22. The intersection 4 is heated and heated, and is squeezed and applied force, so that the first tendon 1 and the second tendon 2 are welded at the intersection 4; then, the first electrode conductor 12 leaves the welding position 3 under the action of the first electrode moving part 11, and does not contact the first tendon 1 and the second tendon 2. The first tendon 1 and the second tendon 2 move relative to each other, and form the next intersection 4 on the second electrode conductor 22. The first electrode conductor 12 approaches the welding position 3 again under the action of the first electrode moving part 11, and the above process continues until the welding is completed. In this process, the first electrode conductor 12 continues to reciprocate relative to the welding position 3, and squeezes and applies force to the intersection 4 under the action of the first electrode moving part 11. In this embodiment, the first electrode conductor 12 can remain conductive throughout the welding process, or it can be energized only when it contacts the intersection 4. The energization state of the first electrode conductor 12 is controlled by the control system.

[0069] Embodiment 2

[0070] When welding starts, the first electrode conductor 12 is driven by the first electrode moving part 11 to approach the welding position 3, and then reaches the welding position 3, and stays at the welding position 3 under the action of the first electrode moving part 11. When the first tendon 1 and the second tendon 2 meet at the welding position 3 to form an intersection 4, the first electrode conductor 12 stays at the welding position 3 and keeps in contact with the intersection 4. The first electrode conductor 12 can be kept in position by the first electrode moving part 11, but the intersection 4 is squeezed and applied. The first electrode conductor 12 is in a energized state and forms a circuit with the intersection 4 and the second electrode conductor 22. The intersection 4 is heated and squeezed, so that the first tendon 1 and the second tendon 2 are connected. The first electrode conductor 12 is welded at the intersection 4; then, the force applied by the first electrode moving part 11 to the first electrode conductor 12 is cancelled. Although the first electrode conductor 12 stays at the welding position 3, it only keeps in contact with the first tendon 1 or the second tendon 2, and does not apply force to the first tendon 1 and the second tendon 2, so as to prevent the first tendon 1 or the second tendon 2 from being deformed by force during movement. At this time, the first electrode conductor 12 is controlled by the control system and is in a non-powered state, which has less influence on the first tendon 1 and the second tendon 2; the first tendon 1 and the second tendon 2 move relative to each other to form the next intersection 4, the first electrode conductor 12 is powered on again, and the force is applied to the intersection 4 under the action of the first electrode moving part 11, and the above process is continued until the welding is completed. In this process, the first electrode conductor 12 is stationary relative to the welding position 3, and the force is applied to the intersection 4 by the first electrode moving part 11 or other additional mechanisms. When the welding is completed, the first electrode conductor 12 leaves the welding position 3 under the action of the first electrode moving part 11, so as to facilitate the removal of the welded steel cage from the welding equipment. In this embodiment, the first electrode moving part 11 includes a spring or a cylinder, which can apply a squeezing force to the intersection 4, so that the first electrode conductor 12 applies a squeezing force to the intersection 4, and the first tendon 1 and the second tendon 2 are firmly welded.

[0071] In order to realize the on and off of the second electrode conductor 22, the second electrode 20 includes a second electrode moving part 21, a conductive plate 23 and a second electrode base 24; the second electrode conductor 22 is arranged on the second electrode base 24 and is arranged opposite to the first electrode conductor 12; the conductive plate 23 has a state of rising and falling under the action of the second electrode moving part 21 and maintaining electrical contact with the second electrode conductor 22. Figure 6As shown, the conductive disk 23 and the second electrode moving part 21 are arranged above the second electrode conductor 22 and the second electrode substrate 24, the conductive disk 23 is electrically connected to one pole of the power supply, the conductive disk 23 is connected to the second electrode moving part 21, and contacts and separates with the second electrode conductor 22 under the action of the second electrode moving part 21, so as to control the power on and off of the second electrode conductor 22. The second electrode conductor 22 in this structure is not directly connected to the electrode of the power supply, so as to avoid the second electrode conductor 22 transmitting vibration to the connection structure with the power supply during the welding process, which affects the stability of the connection structure. The conductive disk 23 is energized by contact with the second electrode conductor 22. As long as the position of the conductive disk 23 is controlled, the power on and off of the second electrode conductor 22 can be guaranteed. When the welding device is not working, the second electrode moving part 21 takes the conductive disk 23 away from the second electrode conductor 22, and the second electrode conductor 22 is naturally powered off, and no loop is generated with the first electrode conductor 12, thereby ensuring storage safety and personnel safety.

[0072] As attached Figure 6 As shown, the second electrode conductor 22 is arranged on the second electrode substrate 24. To fix the second electrode conductor 22, the second electrode substrate 24 includes a first rib fixing block 241 and a substrate 242 connected to the first rib fixing block 241. The substrate 242 and the first rib fixing block 241 are fixedly connected by screws. The first rib fixing block 241 is provided with a first rib through hole 243. The first rib 1 passes through the first rib fixing block 241 through the first rib through hole 243. The second electrode conductor 22 is arranged on the substrate 242. In order to make the connection between the substrate 242 and the first rib fixing block 241 more firmly, it is necessary to increase the contact area between the substrate 242 and the first rib fixing block 241. Preferably, the substrate 242 is an L-shaped substrate 242, the longer side is used to carry the second electrode conductor 22, and the shorter side is used to be fixedly connected to the first rib fixing block 241, so that the second electrode conductor 22 is installed more stably and is not easy to shake during the welding process, which affects the normal welding.

[0073] After the first rib 1 to be welded passes through the first rib fixing block 241, it is located between the first electrode conductor 12 and the second electrode conductor 22. In order to limit the first rib 1 and prevent it from being displaced and causing the intersection point 4 to be offset, the second electrode conductor 22 includes a mounting block 221 and a first rib conductive block 222. The mounting block 221 is arranged on the base 242. The upper surface of the mounting block 221 is provided with a placement groove 223 for placing the first rib 1. The first rib 1 is located in the placement groove 223. The placement groove 223 is adapted to the shape of the first rib 1, and a portion of the first rib 1 is exposed from the placement groove 223, so that the first rib 1 and the second rib 2 can intersect, and the intersection point 4 is located on the second electrode conductor 22, between the first electrode conductor 12 and the second electrode conductor 22. The first rib conductive block 222 is used to contact the conductive disk 23, and the conductive disk 23 is located above the conductive block of the second electrode 20. Therefore, the first rib conductive block 222 is covered on one end of the mounting block 221 close to the fixed turntable 41, and forms a through groove 224 with the placement groove 223 for the first rib 1 to pass through. The first rib 1 passes through the through groove 224 and is partially placed in the placement groove 223. In order to allow the first electrode conductor 12 located above the mounting block 221 to contact the intersection 4, a vacancy corresponding to the welding position 3 is provided on the mounting block 221. The placement groove 223 can be semicircular or inverted trapezoidal. The mounting block 221 is a square structure, and chamfers are provided on both sides to prevent the second main rib spanning the first main rib and the mounting block 221 from colliding with the mounting block 221.

[0074] When the welding device is applied in the welding equipment of the present embodiment, the second electrode 20 is arranged on the fixed assembly component 40, the second electrode conductor 22 and the second electrode substrate 24 are correspondingly circumferentially arranged on the fixed turntable 41, and need to rotate with the fixed turntable 41, and the conductive disk 23 and the second electrode moving part 21 are fixed on the fixed assembly component 40, the second electrode conductor 22 and the second electrode substrate 24 rotate relative to the conductive disk 23, and the conductive disk 23 needs to contact the first rib conductive block 222 of each second electrode conductor 22 in turn, so that the second electrode conductor 22 is energized when it is in the welding position 3, therefore, the first rib conductive block 222 has a circumferential friction force on the conductive disk 23, and in order to avoid excessive wear of the first rib conductive block 222 and the conductive disk 23, as shown in the attached Figure 7 As shown, the top surface of the first rib conductive block 222 is an arc surface, and the conductive disk 23 is a disk. The conductive disk 23 is in point contact or line contact with the top surface of the first rib conductive block 222 under the action of the second electrode moving part 21. At the same time, the conductive disk 23 is rotatably arranged on the second electrode moving part 21, and rotates with the first rib conductive block 222 during the contact process, thereby reducing friction and wear.

[0075] Based on the above embodiment, preferably, the first electrode conductor 12 is connected to the first electrode moving part 11 through the stress adjustment part 13 to relieve the impact force between the first electrode conductor 12 and the intersection 4. The first tendon 1 and the second tendon 2 overlap each other to form the intersection 4, and the first tendon 1 and the second tendon 2 have a certain thickness, so a higher protrusion is formed at the intersection 4. If the second tendon 2 spans over the first tendon 1, and the first electrode conductor 12 is in contact and squeezed at the intersection 4, it is impacted by the protrusion of the intersection 4. After long-term use, the first electrode conductor 12 and the connection part 123 between the first electrode moving part 11 and the first electrode conductor 12 will be impacted and damaged, thereby causing damage to the first electrode conductor 12.

[0076] To install the first electrode conductor 12, the stress adjustment part 13 includes a fixing part 131, and the first electrode conductor 12 is connected to the fixing part 131. In some embodiments, the first tendon 1 and the second tendon 2 are respectively the main tendon and the stirrup in the steel cage, and during the welding process of the steel cage, the main tendon will drive the stirrup to rotate, and the main tendon and the stirrup have circumferential impact force and radial impact force on the first electrode conductor 12, therefore, the stress adjustment part 13 also includes a circumferential force buffer component, which is located between the fixing part 131 and the first electrode moving part 11; and the stress adjustment part 13 also includes a radial force buffer component, which is located between the fixing part 131 and the first electrode moving part 11. In other embodiments, the impact force of the first rib 1 and the second rib 2 on the first electrode conductor 12 is only a circumferential impact force, and the stress adjustment part 13 further includes a circumferential force buffering component, which is located between the fixing part 131 and the first electrode moving part 11; in other embodiments, the impact force of the first rib 1 and the second rib 2 on the first electrode conductor 12 is only a radial impact force, and the stress adjustment part 13 further includes a radial force buffering component, which is located between the fixing part 131 and the first electrode moving part 11. The radial force buffering component may include a radial buffer spring or a radial buffer cylinder, which is compressed when the first electrode conductor 12 is subjected to a radial force, which can not only buffer and protect the first electrode conductor 12, but also make the first electrode conductor 12 more closely contact with the intersection 4, apply a greater extrusion force to the intersection 4, and make the welding of the first rib 1 and the second rib 2 more firmly. The radial buffer spring or the radial buffer cylinder is arranged in the radial extension direction of the intersection 4 of the first electrode conductor 12.

[0077] More specifically, as attached Figure 7As shown, the circumferential force buffer assembly includes a receiving groove 132, a slide bar 133 and an elastic member 134. The fixing member 131 is located in the receiving groove 132 and is sleeved on the slide bar 133. The elastic member 134 is sleeved on the slide bar 133, with one end abutting against the inner wall of the receiving groove 132 and the other end abutting against the fixing member 131. Due to the contractibility of the elastic member 134, the fixing member 131 can be properly moved on the slide bar 133. When the stirrup is uneven, the first electrode conductor 12 contacts the intersection 4 and a circumferential displacement occurs. The fixing member 131 can be properly moved along the force direction. Due to the presence of the elastic member 134, the displacement of the first electrode conductor 12 is limited, so that it does not deviate from the welding position 3. It can also avoid the first electrode conductor 12 from a hard collision with the intersection 4, thereby effectively protecting the first electrode conductor 12. The fixing member 131 , the sliding rod 133 and the elastic member 134 are located in the receiving groove 132 , which can protect these components and is also beneficial to reducing the volume of the circumferential force buffer assembly, thereby reducing the volume of the entire first electrode 10 .

[0078] The first electrode 10 and the second electrode 20 are respectively connected to a power source (not shown), such as two poles of a transformer, and the transformer is controlled by a control system to realize the on and off of the first electrode 10 and the second electrode 20. In some embodiments, the first electrode moving part 11 and the second electrode moving part 21 contain metal conductive materials, so it is necessary to set an insulating member between the first electrode conductor 12 and the first electrode moving part 11, and set an insulating member between the conductive disk 23 and the second electrode moving part 21.

[0079] As attached Figure 7 As shown, the first electrode conductor 12 includes a welding conductive plate 121 and a power-connecting conductive plate 122; the power-connecting conductive plate 122 is provided with a connecting portion 123 for electrically connecting to one pole of a power source; the welding conductive plate 121 is mechanically and electrically connected to the power-connecting conductive plate 122, and is used to directly contact the intersection 4. The main purpose of dividing the first electrode conductor 12 into the welding conductive plate 121 and the power-connecting conductive plate 122 is to facilitate the connection and power supply of the first electrode conductor 12 to a transformer, etc., and at the same time, avoid direct collision with the intersection 4 to affect the connection structure of the first electrode conductor 12 and the transformer, and ensure the connection stability of the first electrode conductor 12 and the power source.

[0080] Since the welding conductive plate 121 will exert force on the intersection 4 during use and rub against the intersection 4, if the welding method in the first embodiment is used, the impact force of the welding conductive plate 121 will be greater, which will cause the welding conductive plate 121 to deform and wear, and eventually cause the welding conductive plate 121 to deviate from the welding position 3, resulting in insufficient welding force or misalignment. Preferably, the welding conductive plate 121 includes at least one replaceable conductor. When the welding conductive plate 121 is damaged, the conductor in contact with the intersection 4 is removed and replaced with a new conductor to ensure that there is no deviation in the welding. Such a structure does not require the entire first electrode conductor 12 to be replaced, which is conducive to reducing the cost of use. The conductors are fixed to each other by screws, and the welding conductive plate 121 and the power-connecting conductive plate 122 can also be fixedly connected by screws.

[0081] As attached Figure 7 As shown, an extension portion (not shown) is provided at one end of the power-connecting conductive plate 122, and the extension portion extends toward the power source and is used to install a power-connecting copper plate (not shown), which is used to achieve electrical connection between the first electrode conductor 12 and one pole of the power source.

[0082] Preferably, in order to enhance the conductivity of the first electrode conductor 12 and to better guide the current to form a current loop at the intersection 4, the connecting conductive plate 122 and the welding conductive plate 121 are both made of conductive copper material.

[0083] The first electrode conductor 12 is prone to generate a large amount of heat during the power-on and welding process. In order to protect the first electrode conductor 12 and avoid overheating, a cooling structure is provided on the first electrode conductor 12. The cooling structure includes a coolant inlet 124, a cooling channel (not shown) and a coolant outlet (not shown). The cooling channel is located inside the first electrode conductor 12, and the coolant inlet 124 and the coolant outlet are connected to the cooling channel.

[0084] Based on the above embodiment, the cooling structure can be set in the power-connecting conductive plate 122, and can also be set in any conductor in the welding conductive plate 121. The power-connecting conductive plate 122 and the welding conductive plate 121 are both made of metal materials with good thermal conductivity. Therefore, the coolant of the cooling structure can act on other conductors without a cooling structure.

[0085] In some embodiments, in order to install the first electrode moving part 11 and the second electrode moving part 21, the welding device also includes an electrode holder 30, and the electrode holder 30 includes a first electrode support frame 31, a second electrode support frame 32, a first electrode connecting plate 33 and a first electrode connecting plate 33; the first electrode conductor 12 is connected to the first electrode connecting plate 33, the first electrode moving part 11 is connected to the first electrode support frame 31, and drives the first electrode conductor 12 and the first electrode connecting plate 33 to move along the first guide groove on the first electrode support frame 31; the second electrode conductor 22 is connected to the second electrode connecting plate 34, the second electrode moving part 21 is connected to the second electrode support frame 32, and drives the second electrode conductor 22 and the second electrode connecting plate 34 to move along the second guide groove on the second electrode support frame 32; the first electrode support frame 31 and the second electrode support frame 32 are arranged side by side.

[0086] More specifically, as attached Figure 6 and attached Figure 7 As shown, the first electrode support frame 31 includes a first side plate 314 and a first mounting plate, the first mounting plate includes a first positioning plate 311 connected to the first side plate 314, a first top plate 312 and a first guide plate 313 for mounting the first movable cylinder 111, the first positioning plate 311, the first top plate 312 and the first guide plate 313 are perpendicular to each other, the first top plate 312 is provided with a first guide hole, the movable rod of the first movable cylinder 111 passes through the first guide hole and is connected to the first electrode connecting plate 33 thereunder, a guide rail 35 is installed on the first guide plate 313, the first electrode connecting plate 33 is slidably matched with the guide rail 35, and moves along the guide rail 35 under the action of the movable rod of the first movable cylinder 111, the first electrode conductor 12 is arranged at the bottom of the first electrode connecting plate 33 through a circumferential force buffer assembly, and can move along the guide rail 35 following the first electrode connecting plate 33. The first moving cylinder 111 may be a hydraulic cylinder or a pneumatic cylinder, which may be used as a force applying device for the first electrode conductor 12 to the intersection 4, or may be used as a radial buffer structure to control the electrode conductor to move slightly.

[0087] The second electrode support frame 32 includes a second side plate 321 and a second mounting plate. The second mounting plate includes a second positioning plate 322 connected to the second side plate 321, a second top plate 323 for mounting the second movable cylinder 211, and a second guide plate 324. The second positioning plate 322, the second top plate 323, and the second guide plate 324 are perpendicular to each other. A second guide hole is provided on the second top plate 323. The movable rod of the second movable cylinder 211 passes through the second guide hole and is connected to the second electrode connecting plate 34 below it. A guide rail 35 is installed on the second guide plate 324. The second electrode connecting plate 34 slides with the guide rail 35 and moves along the guide rail 35 under the action of the movable rod of the second movable cylinder 211. The conductive plate 23 is arranged at the lower half of the second electrode connecting plate 34 and can be connected to the guide rail 35 and move along the guide rail 35 following the second electrode 20. Preferably, in some embodiments, a rotating shaft mounting seat is provided at the lower half of the second electrode connecting plate 34, a rotating shaft hole or a rotating shaft is provided at the center of the conductive plate 23, and the conductive plate 23 is rotatably connected to the rotating shaft mounting seat through the rotating shaft. The first guide groove and the second guide groove are respectively disposed on the guide rails 35 on the first guide plate 313 and the second guide plate 324 .

[0088] To facilitate processing and installation, the first electrode support frame 31 and the second electrode support frame 32 are arranged on the same fixed plate, and adjustment grooves corresponding to the first electrode support frame 31 and the second electrode support frame 32 are respectively provided on the fixed plate to fine-tune the relative positions of the first electrode support frame 31 and the second electrode support frame 32 and the fixed turntable 41.

[0089] The welding device of the present invention can be arranged on the top, left and right sides or bottom of the fixed assembly component 40, and the positional relationship between the electrode conductor and the electrode moving part in the welding device will change with the assembly position. For example, if the welding device is arranged on the top of the fixed assembly component 40, the electrode moving part is located above the electrode conductor, driving the electrode conductor to move up and down; if the welding device is arranged on both sides of the fixed assembly component 40, the electrode moving part is located on the outside of the electrode conductor, driving the electrode conductor to move left and right; if the welding device is arranged at the bottom of the fixed assembly component 40, the electrode moving part is located below the electrode conductor, driving the electrode conductor to move left and right. For the convenience of description, the present invention uses the orientation in the accompanying drawings to express the positional relationship, which cannot be understood as limiting the specific protection scope of the present invention and does not affect its positional relationship during actual use. As shown in the attached figure Figure 2 and attached Figure 6 In the specific example shown in FIG. 4 , the welding device is located at the upper part of the fixed assembly component 40 .

[0090] The second tendon 2 can be a stirrup, and the unused portion is stored in a stirrup shelf (not shown). In order to reduce the footprint, the stirrups are generally wound on the stirrup shelf, and the diameter of the wound stirrups is small, which is inconsistent with the diameter of the steel cage to be manufactured. Therefore, in some embodiments, the steel cage welding device also includes a second tendon reinforcement assembly 70, and the second tendon reinforcement assembly 70 includes a second tendon straightening assembly 71, which is used to properly straighten the second tendon 2 so that the second tendon 2 is more closely fitted to the first tendon 1 and it is easier to form an intersection 4.

[0091] To guide the second tendon 2 to intersect with the first tendon 1, as shown in the attached Figure 1 As shown, the second tendon straightening component 71 is arranged on one side of the fixed assembly component 40; preferably, the second tendon reinforcement component 70 also includes a second tendon guide portion 72; the second tendon guide portion 72 is located on the side of the first electrode 10 or the side of the fixed assembly component 40, and is used to guide the second tendon 2 to between the first electrode 10 and the second electrode 20, and overlap with the first tendon 1.

[0092] In some embodiments, the second tendon straightening assembly 71 is set on the support frame 63 of the fixed assembly assembly 40 through a bracket, and includes a straightening wheel group 711 and an introduction hole.

[0093] In other embodiments, the second tendon straightening assembly 71 includes a straightening wheel set 711, an angle adjustment assembly 712 and an introduction hole. The angle adjustment assembly 712 is used to cope with welding positions 3 and second tendons 2 of different heights to meet the overlap requirements of the second tendon 2 and the first tendon 1. The straightening wheel set 711 is arranged on the angle adjustment assembly 712, and the angle with the welding position 3 is adjusted by the angle adjustment assembly 712. The straightening wheel set 711 includes a first wheel set and a second wheel set. The distance between the first wheel set and the second wheel set is adjustable to adapt to second tendons 2 of different diameters, so as to achieve a better straightening effect. In order to better introduce the second tendon 2, the introduction hole is located on one side of the straightening wheel set 711, and is arranged corresponding to the gap between the first wheel set and the second wheel set. The first wheel set and the second wheel set include at least one wheel body. As shown in the attached Figure 6 As shown, the number of wheel bodies in the first wheel group is one, and the number of wheel bodies in the second wheel group is one.

[0094] As attached Figure 1 As shown, in some embodiments, in order to facilitate the unloading of the welded steel cage, the welding equipment also includes a unloading device 80.

[0095] The material unloading device 80 includes a material receiving platform 81 and a material receiving frame 82 . The material receiving platform 81 is movably arranged on the material receiving frame 82 . The material receiving frame 82 is provided with a plurality of mounting positions, and the material receiving platform 81 is installed in the mounting positions of the material receiving frame 82 .

[0096] The material receiving platform 81 includes a material receiving component 811 and a moving component 812 . The material receiving component 811 is disposed on the moving component 812 . The moving component 812 drives the material receiving component 811 to move closer to or farther from the first rib body 1 assembly portion to supplement the length of the material receiving component 811 .

[0097] The material receiving assembly 811 includes a material receiving rod 813, a first guide groove 814 and a first pushing component 815. The first pushing component 815 drives the material receiving rod 813 to move along the first guide groove 814; the material receiving rod 813 contacts or separates from the lower surface of the steel cage under the action of the pushing component.

Adjacent guide rail units are spliced ​​with each other to form a guide rail 60 of appropriate length, and the connection is ensured to be flat to meet the use requirements of the welding machine. There are many ways of splicing. In some embodiments, in order to ensure the use strength requirements of the guide rail 60, the guide rail 60 is made of steel, and the adjacent guide rail units are connected to each other by welding; in other embodiments, a detachable splicing structure is provided at both ends of the guide rail unit, so that the guide rail unit is more flexible to use, and the length of the entire guide rail 60 can be quickly changed to meet the welding requirements, and the welding equipment can be more conveniently transferred to the workplace, reducing the footprint of the entire welding equipment and facilitating transportation.

[0100] The structural design of the guide rail unit itself, more specifically, the movement needs to move on the guide rail 60, so each guide rail unit needs to meet the movement requirements of the mobile assembly component 50, as shown in the attached Figure 1As shown, the guide rail unit includes a rail and a support frame 63. The rail and the support frame 63 overlap each other. The two rails are arranged parallel to each other, used to carry the moving assembly component 50 and enable the moving assembly component 50 to move smoothly thereon. The support frame 63 is used to enhance the mechanical strength of the rail and ensure a constant distance between the two rails; as shown in the appendix Figure 2 and the appendix Figure 3 As shown, the docking part is arranged on the rail. The docking part mainly plays a role in connecting with the welding machine. In some embodiments, the welding machine includes a fixed assembly component 40 and a moving assembly component 50. When both the fixed assembly component 40 and the moving assembly component 50 are arranged on the guide rail 60, the guide rail 60 needs to have docking parts corresponding to the fixed assembly component 40 and the moving assembly component 50 respectively. And when only the moving assembly component 50 is arranged on the guide rail 60, the docking part may only include a structure for docking with the moving assembly component 50.

[0101] More specifically, when the moving assembly component 50 is arranged on the guide rail 60, the docking part includes a transmission component arranged inside the rail. The moving assembly component 50 in the welding machine is in transmission connection with the transmission component and moves along the guide rail 60; when the fixed assembly component 40 is also arranged on the guide rail 60, the docking part includes a mounting plane 66 arranged on the rail for mounting the fixed assembly component 40 in the welding machine, as shown in the appendix Figure 3 As shown, the fixed assembly component 40 can be welded or fixed to the rail by screws.

[0102] As shown in the appendix Figure 5 As shown, the transmission component includes a rack 611. The moving assembly component 50 includes a gear assembly meshing with the rack 611. More specifically, the rail includes an inner rail 61 and an outer rail 62 arranged in parallel. The rack 611 is arranged laterally on the inner rail 61, and there is a groove 65 between the inner rail 61 and the outer rail 62. A transmission gear (not shown) is arranged at the bottom of the moving assembly component 50. The transmission gear meshes with the rack 611. The moving assembly component 50 includes a moving motor 552 connected to the transmission gear. The moving motor 552 drives the transmission gear to rotate and drives the moving assembly component 50 to move along the rack 611. The moving assembly component 50 further includes a limiting structure. The limiting structure includes a first limiting block 553. The first limiting block 553 is clamped with the groove 65, so as to ensure the tight meshing between the transmission gear and the rack 611; in another embodiment, a guide bar 64 is arranged on the outer side of the outer rail 62. The guide bar 64 is arranged horizontally. The limiting structure includes a second limiting block 554. The second limiting block 554 is in a "C" shape. One end is connected to the bottom plate 678 of the moving assembly component 50, and the other end is clamped with the guide bar 64 to prevent the moving assembly component 50 from detaching from the guide rail 60. Preferably, the number of the second limiting blocks 554 is 4, which are respectively arranged at the four corners of the bottom plate 678 and are all clamped with the guide bar 64.

[0103] In order to improve the degree of automation of the welding equipment, the guide rail unit also includes an electronic component (not shown), which is mainly used to detect the position of the mobile assembly component 50 and feed back to the control system to control the welding progress. In order to ensure smooth transmission of electrical signals of the entire guide rail 60, the splicing structure includes an electrical connection component (not shown), and adjacent guide rail units realize mechanical and electrical connection of the electronic component through the electrical connection component. The electrical connection component can be an electrical plug connector and an electrical socket. Preferably, the electronic component includes a sensor, which is used to sense the position of the material and send an electrical signal to the lifting device 67 to control the lifting device 67 to support the steel cage between the mobile assembly component 50 and the fixed assembly component 40.

[0104] In some embodiments, as shown in the attached Figure 3 As shown, the guide rail unit also includes a lifting device 67 for lifting materials. The lifting device 67 is directly combined with the guide rail unit to form a modular component. The guide rail unit and the lifting device 67 are correspondingly arranged and can be used directly after splicing without the need to install the lifting device 67 separately, thereby further improving the production installation efficiency.

[0105] More specifically, as attached Figure 8 and attached Fig. 9 As shown, the lifting device 67 includes a lifting support assembly and a lifting platform. The lifting support assembly includes a power mechanism 671 and a connecting rod assembly 672. The power mechanism 671 is connected to one end of the connecting rod assembly 672 and drives the connecting rod assembly 672 to rise and fall; the lifting platform is arranged at the other end of the connecting rod assembly 672 and follows the rising and falling of the connecting rod assembly 672; the power mechanism 671 includes a power cylinder 673, an angle gear 674 and a transmission rack 675. The angle gear 674 is arranged at one end of the connecting rod assembly 672, and the transmission rack 675 is arranged on the top rod of the power cylinder 673. The transmission rack 675 is meshed with the angle gear 674, and the angle gear 674 is driven to rotate under the action of the top rod, thereby driving the connecting rod to rise and fall.

[0106] The power assembly controls the moving distance of the transmission rack 675, thereby controlling the rotation angle of the angle gear 674, and controlling the rotation angle and lifting height of the connecting rod assembly 672. The transmission rack 675 and the angle gear 674 cooperate stably, so that the connecting rod assembly 672 will no longer move after reaching the set height, and the steel cage can be lifted more stably. The moving distance of the transmission rack 675 is more controllable, and the height of the connecting rod assembly 672 can be adjusted more conveniently, which is suitable for steel cages of different sizes.

[0107] In some embodiments, to ensure stable installation of the lifting assembly, the lifting assembly also includes a mounting plate 676, and the lifting support structure is arranged on the mounting plate 676; a support plate is provided on the mounting plate 676, and one end of the connecting rod assembly 672 is rotatably connected to the support plate.

[0108] In some embodiments, a limiting groove 677 is provided on the mounting plate 676, and the transmission rack 675 is movably arranged in the limiting groove 677 to ensure that the transmission rack 675 moves straight, so that the lifting height of the connecting rod assembly 672 can be controlled by controlling the moving distance of the transmission rack 675; the limiting groove 677 can be a groove 65 on the mounting plate 676. In some embodiments, the limiting groove 677 can also be two limiting plates arranged on the mounting plate 676, and the two limiting plates are arranged relatively spaced to form the limiting groove 677; the transmission rack 675 is located between the two limiting plates, which is convenient for processing, so that the transmission rack 675 can be more easily connected to the power device.

[0109] Preferably, the power device is a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, and the power device is connected to the transmission rack 675 and drives the transmission rack 675 to move.

[0111] More specifically, to ensure parallel lifting of the lifting platform and better support of the steel cage, as shown in the attached Fig. 9 As shown, the connecting rod assembly 672 adopts a four-link structure, including a first connecting rod 6721 and a second connecting rod 6722, and the first connecting rod 6721 and the second connecting rod 6722 are arranged in parallel; one end of the first connecting rod 6721 is rotatably set on the mounting plate 676, and the other end is rotatably connected to the base plate 678, and one end of the second connecting rod 6722 is rotatably set on the mounting plate 676, and the other end is rotatably connected to the base plate 678; a second support plate is provided at the bottom of the base plate 678, and the first connecting rod 6721 and the second connecting rod 6722 are rotatably connected to the second support plate.

[0112] As attached Fig. 9 As shown, the first connecting rod 6721 or the second connecting rod 6722 includes two relatively arranged long rods and a short rod located between the two long rods, so as to enhance the mechanical strength of the first connecting rod 6721 and the second connecting rod 6722. One end of the long rod is rotatably connected to the mounting plate 676, and the other end is rotatably connected to the base plate 678. A plurality of short rods are arranged between the long rods at intervals, wherein the first short rod is located between the rotating connection point between the long rod and the mounting plate 676. Preferably, the angle gear 674 is arranged on the first short rod, so that the rotation of the angle gear 674 can be more accurately transmitted to the connecting rod assembly 672, thereby more accurately controlling the smooth lifting and lowering of the lifting platform.

[0113] In order to realize automatic control and improve the accuracy of the lifting support, the lifting assembly also includes a detection module (not shown), which is arranged corresponding to the transmission rack 675 and is used to detect the moving distance of the transmission rack 675, so as to calculate the lifting height of the lifting platform. Preferably, the detection module includes a displacement sensor arranged on the mounting plate 676, and the displacement sensor is arranged on one side of the transmission rack 675. In other embodiments, a distance sensor can also be arranged at the bottom of the lifting platform to directly detect the lifting height of the lifting platform.

[0114] In some embodiments, the first rib 1 passes through the fixed assembly component 40 and the movable assembly component 50 in sequence and is fixedly connected to the movable assembly component 50; the fixed assembly component 40 includes a fixed turntable 41, a first support component 42 and a first rotating component 43, the first rotating component 43 and the fixed turntable 41 are arranged on the first support component 42, and the fixed turntable 41 rotates under the action of the first rotating component 43; the movable assembly component 50 includes a movable turntable 51, a second support component 52 and a second rotating component 53, and the movable turntable 51 rotates under the action of the second rotating component 53, and the control system is respectively connected to the first rotating component 43 and the second rotating component 53, and controls the first rotating component 43 and the second rotating component 53 to make the rotation speeds of the fixed turntable 41 and the movable turntable 51 consistent.

[0115] More specifically, as attached Figure 3 As shown, the first rotating component 43 and the second rotating component 53 both include a rotating motor 431, a rotating gear plate 432 and a stabilizing component. The rotating gear plate 432 is transmission-connected to the rotating motor 431. The stabilizing component is connected to the rotating gear plate 432 and rotates with the rotating gear plate 432. The stabilizing component is used to position the movable turntable 51 or the fixed turntable 41 and drive the movable turntable 51 or the fixed turntable 41 to rotate.

[0116] The stabilizing component should ensure that the movable turntable 51 or the fixed turntable 41 can rotate stably while positioning the movable turntable 51 or the fixed turntable 41. Therefore, the stabilizing component includes a plurality of rollers 433, a rotating ring 434 and a ring bracket 435.

The rotating toothed disc 432 can be meshed with the gear on the output shaft of the rotating motor 431 to transmit power. The position of the rotating toothed disc 432 follows the position of the rotating motor 431. Preferably, in order to avoid the rotating toothed disc 432 interfering with the fixed rotating disc 41 and the ribs thereon, as shown in the attached Figure 4 As shown, the rotating gear plate 432 is arranged outside the annular portion 436.

[0117] As attached Figure 3 As shown, the fixed turntable 41 includes a first fixed disk 411, a tendon guide portion 412 and a first tendon fixing block 241.

After the tendon passes through the tendon guide portion 412, it passes out from the first tendon fixing block 241. In order to be suitable for steel cages of different sizes, a first positioning block 414 is connected to the first tendon fixing block 241, and the first tendon fixing block 241 is embedded and moved on the first size adjustment slot 413 through the first positioning block 414.

[0118] As attached Figure 5As shown, correspondingly, in order to cope with steel cages of different diameters, the movable turntable 51 includes a second fixed disk 511, a locking structure 512, and a second tendon fixing block 513. A plurality of second size adjustment grooves 514 are circumferentially arranged on the second fixed disk, and the second tendon fixing block 513 can be adjusted and arranged in the second size adjustment groove 514; the locking structure 512 is used to penetrate the second tendon fixing block 513 and fix the tendon.

When the first fixed disk 411 and the second fixed disk adjust the positions of the first positioning block 414 and the second positioning block 515, the first through hole 44 and the second through hole 54 on the first tendon fixing block 241 and the second tendon fixing block 513 are controlled to align, so as to ensure that the diameter of the steel cage is consistent.

[0119] The mobile assembly component 50 not only drives the steel cage to rotate, but also drives the steel cage to move. During the movement process, the stability of the mobile assembly component 50 is particularly important. Therefore, the mobile assembly component 50 also includes a mobile platform 55, and the mobile platform 55 includes a mobile body 551 and a transmission structure; the second support component 52, the mobile turntable 51 and the second rotating component 53 are arranged on the mobile body 551; the mobile body 551 is mounted on the guide rail 60 and moves along the guide rail 60; the transmission structure includes a mobile motor 552 and a transmission component, the transmission component is arranged on the mobile body 551, and includes a transmission gear (not drawn), the mobile motor 552 drives the transmission component to rotate, and the mobile body 551 is driven to move through the engagement of the transmission component with the rack 611 on the guide rail 60; the mobile platform 55 also includes a limiting structure, which is a limiting block arranged on the mobile body 551, and the limiting block is engaged with the guide rail 60 to enable the mobile platform 55 to move along the guide rail 60.

[0120] The first rotating assembly 43 and the second rotating assembly 53 are controlled by a control system to achieve a uniform rotation speed. However, due to the heavy weight of the steel cage, the pressure on the fixed turntable 41 and the movable turntable 51 increases during the welding process, which can easily cause the rotation speeds of the fixed turntable 41 and the movable turntable 51 to change. Therefore, the first reinforcement body 1 assembly part also includes a sensor (not shown), and the sensor includes a position sensor and a distance sensor; the position sensor is arranged on the movable turntable 51 and the fixed turntable 41, and is used to monitor the rotation synchronization of the movable turntable 51 and the fixed turntable 41; the distance sensor is arranged on the guide rail 60, and is used to detect the position of the movable assembly assembly 50.

[0121] The present invention also provides a steel cage welding method, which uses the steel cage welding device in the above embodiment and includes the following steps:

[0122] The step of loading the first tendon 1: pass the first tendon 1 through the first through hole 44 and the second through hole 54 on the fixed assembly component 40 and the movable assembly component 50 in sequence, one end of the first tendon 1 is detachably fixedly connected to the movable assembly component 50, and the first tendon 1 is movably connected to the first through hole 44 of the fixed assembly component 40, so that the first tendon 1 can move relative to the first through hole 44; in this step, the first tendon 1 can be loaded manually or automatically by an automatic loading device.

[0123] The first rib body 1 moving step: starting the moving assembly component 50, so that the moving assembly component 50 drives the first rib body 1 to move in a direction away from the fixed assembly component 40, and the first rib body 1 passes through the first through hole 44 on the fixed assembly component 40;

[0124] The first muscle body 1 rotation step: in the process of the movable assembly component 50 driving the first muscle body 1 to move, the movable assembly component 50 and the fixed assembly component 40 rotate synchronously and drive the first muscle body 1 to rotate;

[0125] Welding steps: the second electrode 20 is powered, the first tendon 1 passes through the second electrode conductor 22 and contacts the second electrode conductor 22, and the second tendon 2 is guided to cross over the first tendon 1, so that the second tendon 2 overlaps with the first tendon 1 to form an intersection 4, and the intersection 4 is located between the first electrode conductor 12 and the second electrode conductor 22; the powered first electrode conductor 12 is close to the welding position 3 under the action of the first electrode moving part 11, and the intersection 4 is applied with force and energized, and the first electrode 10, the second electrode 20 and the intersection 4 of the first tendon 1 and the second tendon 2 form a conductive loop to weld and fix the second tendon 2 with an intersection 4 of the first tendon 1; the first tendon 1 continuously rotates under the action of the fixed turntable 41 and the movable turntable 51, pulling the second tendon 2, so that the second tendon 2 forms a new intersection 4 with the first tendon 1 below the first electrode conductor 12; the first electrode conductor 12 applies force and energizes the intersection 4 until the welding is completed.

[0126] Preferably, the second electrode 20 can be connected to electricity in the following manner: the conductive disk 23 is connected to electricity and electrically contacts the second electrode conductor 22 under the action of the second electrode moving part 21, and the second electrode conductor 22 is energized. Correspondingly, the second electrode 20 is disconnected from electricity in the following manner: the second electrode conductor 22 rises under the action of the second electrode moving part 21 and is separated from the second electrode conductor 22.

[0127] The second electrode conductor 22 is not directly connected to the electrode of the power source, so as to prevent the second electrode conductor 22 from transmitting vibration to the connection structure with the power source during the welding process, thereby affecting the stability of the connection structure. The second electrode conductor 22 is powered by the contact between the conductive disk 23 and the second electrode conductor 22. As long as the position of the conductive disk 23 is properly controlled, the power on and off of the second electrode conductor 22 can be ensured. When the welding device is not working, the second electrode moving part 21 takes the conductive disk 23 away from the second electrode conductor 22, and the second electrode conductor 22 is naturally powered off, and no loop is generated with the first electrode conductor 12, thereby ensuring storage safety and personnel safety.

[0128] Based on the structure of the first electrode conductor 12 in the first embodiment, the welding method adopted can be: the first electrode conductor 12 approaches the welding position 3 under the action of the first electrode moving part 11, and applies force to the intersection 4 for welding.

At the same time, the first electrode conductor 12 approaches the welding position 3 again under the action of the first electrode moving part 11, and applies force to the intersection 4 for welding, and repeats this process until the welding is completed.

[0129] Based on the structure of the first electrode conductor 12 in the second embodiment, the welding method adopted can be: the first electrode conductor 12 approaches the welding position 3 under the action of the first electrode moving part 11, and applies force to the intersection 4 for welding. After completing the welding of one intersection 4, the first electrode conductor 12 stays at the welding position 3 and stops applying force and conducting electricity to the first tendon 1 and the second tendon 2. The next intersection 4 is formed and located between the first electrode conductor 12 and the second conductor. The first electrode conductor 12 applies force to the intersection 4 again for welding, and repeats this process until the welding is completed.

[0131] Preferably, in some embodiments, in order to support the partially welded steel cage, a steel cage supporting step is also included: when the mobile assembly component 50 moves along the guide rail 60, the partially welded steel cage is driven to move. At the same time, a lifting device 67 arranged on the guide rail 60 and located below the steel cage controls the lifting platform to be lifted under the action of the lifting support structure after detecting the passage of the mobile assembly component 50, and contacts the lower surface of the steel cage and supports the steel cage to prevent the steel cage from sagging and deforming due to its own gravity.

[0132] Preferably, in some embodiments, the steel cage unloading steps are: the lifting device 67 supports the steel cage until welding is completed, the mobile assembly component 50 drives the steel cage to continue to move until one end of the first tendon 1 is separated from the fixed assembly component 40, and then the connection between the mobile assembly component 50 and the first tendon 1 is released, and the mobile assembly component 50 continues to move forward until the other end of the first tendon 1 is separated from the mobile assembly component 50; the material receiving component 811 approaches the steel cage under the action of the mobile component 812, and the material receiving rod 813 contacts the lower surface of the steel cage under the action of the first pushing component 815, the lifting device 67 descends, and the steel cage is placed on the material receiving rod 813, and rolls along the material receiving rod 813 to the material receiving machine frame 82, and rolls along the inclined surface of the material receiving machine frame 82 to the placement position, realizing automatic unloading, effectively improving the unloading efficiency, and avoiding damage to the steel cage due to human handling.
