Description

Technical Field

[0001] The invention relates to the technical field of steel bar cage weaving, in particular to rigid frame forming equipment for construction. Background Art

[0002] The rigid frame roll welding machine is a machine that spirally wraps stirrups around multiple main bars and welds the two. The rigid frame roll welding machine can connect multiple main bars into a rigid frame through stirrups, and the frame can be further poured with concrete to form a reinforced concrete structure, which is widely used in the construction field.

[0003] The welding equipment of the rigid frame rolling welding machine mainly includes an electrode disk in the shape of a cross-section of a steel frame, a welding arm rotating around the electrode disk, and a conductive device. The electrode disk has a plurality of grooves for accommodating main bars, and the welding arm has grooves for accommodating stirrups. The main bars and stirrups are brought into contact and welded together by pressing the welding arm against the electrode disk to form a steel frame.

[0004] The main reinforcement has good plasticity and toughness, and the groove of the electrode disk that accommodates the main reinforcement has the same diameter as the main part of the main reinforcement. During the reinforcement insertion process, the main reinforcement is easily bent due to its own weight, resulting in the main reinforcement being unable to be smoothly inserted longitudinally into the groove of the electrode disk. It is usually necessary to manually place the main reinforcement into the groove of the electrode disk. The rigid skeleton has a large number of main reinforcements and is heavy, so manual reinforcement insertion requires a lot of manpower. Summary of the invention

[0005] The purpose of the present invention is to provide a rigid frame forming device for construction, so as to solve the problem that manual reinforcing bar threading requires a lot of manpower.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the main reinforcement is placed on the frame and the main reinforcement can be moved longitudinally under the drive of the reinforcement moving device. The main reinforcement is moved longitudinally under the drive of the reinforcement moving device to pass over the movable electrode plate and be placed on the electrode plate. During welding, the outer electrode drives the stirrup to press against the main reinforcement, so that an effective weld is formed between the main reinforcement and the stirrup to form a rigid skeleton. During the welding process, the reinforcement moving device still drives the main reinforcement to move longitudinally, so that the stirrup can be continuously welded to the main reinforcement along the longitudinal direction of the main reinforcement, and the degree of automation is high. In detail, before the main reinforcement is sent to the movable electrode plate, the first distance adjustment component drives the movable electrode plate to move closer to each other to avoid the main reinforcement from sagging at the end under the action of its own gravity during the transfer process, causing interference between the main reinforcement and the movable electrode plate, thereby causing the main reinforcement to be unable to pass over the movable electrode plate.

[0057] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0059] The length direction of the rigid frame is the longitudinal direction, the width direction of the rigid frame is the transverse direction, and the height direction of the rigid frame is the vertical direction. The ends of the main reinforcement are upset to form a pier head for clamping the main reinforcement nut.

[0060] Embodiment 1

[0061] like Figure 1 , 8 As shown in FIGS. 9, 15 and 16, this embodiment provides a rigid frame forming device for construction, comprising a frame 1, a reinforcement moving device for driving a plurality of main reinforcements to move synchronously along the longitudinal direction of the frame 1, and a welding device arranged on the longitudinal moving path of the main reinforcements for welding the main reinforcements and stirrups;

[0062] The welding device comprises a welding frame 2, a central electrode 6 mounted on the welding frame 2, and an outer electrode 3;

[0063] The central electrode 6 includes two movable electrode plates 61 , and each movable electrode plate 61 is driven by the first distance adjustment component to move closer to or farther from each other.

[0064] Specifically, the main reinforcement is placed on the frame 1 and the main reinforcement can be moved longitudinally under the drive of the reinforcement moving device. The main reinforcement is moved longitudinally under the drive of the reinforcement moving device to pass through the active electrode plate 61 and is placed on the electrode plate 61. During welding, the outer electrode 3 drives the stirrup to press against the main reinforcement, so that an effective weld is formed between the main reinforcement and the stirrup to form a rigid skeleton. During the welding process, the reinforcement moving device still drives the main reinforcement to move longitudinally, so that the stirrup can be continuously welded to the main reinforcement along the longitudinal direction of the main reinforcement, and the degree of automation is high. In detail, before the main reinforcement is sent to the active electrode plate 61, the first distance adjustment component drives the active electrode plate 61 to move closer to each other to avoid the main reinforcement from sagging at the end under the action of its own gravity during the transfer process, causing interference between the main reinforcement and the active electrode plate 61, thereby causing the main reinforcement to be unable to pass over the active electrode plate 61. The present invention can ensure that all main reinforcements can pass over the active electrode plate 61 of the center electrode 6, so that all main reinforcements can be welded with the stirrup to form a rigid skeleton, and there is no need to manually thread the main reinforcement, which is efficient and greatly reduces labor costs.

[0065] In this embodiment, the cross-sectional shape of the rigid frame is a rectangle and main ribs are arranged on two long sides of the rectangle. There are two movable electrode plates 61 , which respectively correspond to the main ribs on the long sides of the rectangular rigid frame.

[0066] like Figure 1 , 3As shown in 4-7, further, the reinforcement moving device includes a reinforcement conveying mechanism 7 for conveying the main reinforcement; the reinforcement conveying mechanism 7 includes a frame 71, a translation assembly installed on the frame 71, a second distance adjustment assembly installed on the translation assembly, and a reinforcement clamping plate 108 installed on the second distance adjustment assembly. The reinforcement clamping plate 108 is provided with a clamping claw 104 for clamping the main reinforcement, and the clamping claw 104 is connected to a clamping claw drive for driving the clamping claw 104 to clamp the main reinforcement. The main reinforcement is clamped by the reinforcement clamping plate 108 and the clamping claw 104 provided on the reinforcement clamping plate 108. The translation assembly drives the clamped main reinforcement to move longitudinally to realize the conveying of the main reinforcement, thereby realizing the automatic conveying of the main reinforcement, avoiding manual conveying, improving the conveying efficiency of the main reinforcement, and thus improving the manufacturing efficiency of the rigid skeleton. During the transportation of the main reinforcement, the position of the main reinforcement can be adjusted by the second distance adjustment component, which is convenient for producing rigid skeletons of different sizes; at the same time, when the main reinforcement is arranged in the horizontal direction and transported to the frame 1 in the horizontal direction, the position of the clamping plate 108 is adjusted by setting the second distance adjustment component to avoid interference with the transportation of the main reinforcement, that is, when the main reinforcement is transported to the frame 1, the clamping plate 108 rises, and after the main reinforcement is transported, the clamping plate 108 drops, and the main reinforcement is limited and clamped, and after the main reinforcement is limited and clamped, the clamping plate 108 is driven to rise and then the main reinforcement is longitudinally transported. In detail, the clamping jaw drives the clamping jaw 104 to rotate and clamp the main reinforcement to the clamping plate 108. Further, in order to improve the efficiency of reinforcement delivery, multiple clamping jaws 104 are arranged at equal intervals on the clamping plate 108, and multiple main reinforcements are clamped by multiple clamping jaws 104 at the same time, so that multiple main reinforcements can be delivered at the same time. Furthermore, when the clamping plate 108 clamps multiple main bars at the same time, in order to improve the synchronization of the clamping action, the same drive is used to drive multiple clamping jaws 104 to move. Specifically, the clamping jaw drive includes a driving plate 102, a clamping driving member 106 and a plurality of traction members 103. The driving plate 102 is slidably mounted on the clamping plate 108. The clamping driving member 106 is mounted on the driving plate 102 and the driving end is connected to the clamping plate 108. Preferably, the clamping plate 108 is provided with a fixed column 105 connected to the output end of the clamping driving member 106. A plurality of traction members 103 are installed on the driving plate 102 at intervals in the lateral direction. The traction members 103 correspond to and are connected to the clamping jaws 104. The clamping driving member 106 can drive the driving plate 102 to move horizontally to drive the traction member 103 to move horizontally, thereby driving the clamping surface of the clamping jaw 104 to rotate in a direction close to or away from the clamping plate 108. Among them, when clamping the main reinforcement, the clamping drive 106 drives the driving plate 102 to move horizontally to drive the traction member 103 to move horizontally, thereby driving the clamping surface of the clamping jaw 104 to rotate toward the direction close to the clamping plate 108; when releasing the main reinforcement, the clamping drive 106 drives the driving plate 102 to move horizontally to drive the traction member 103 to move horizontally, thereby driving the clamping surface of the clamping jaw 104 to rotate toward the direction away from the clamping plate 108; the clamping drive 106 can be one of a pneumatic cylinder, an oil cylinder, and an electronic telescopic rod.Preferably, in order to prevent the clamping drive member 106 from being damaged by force, the two ends of the clamping drive member 106 are respectively hinged to the drive plate 102 and the clamping plate 108; preferably, the clamping jaw 104 has a connecting portion, which is adapted to the end of the corresponding traction member 103 away from the drive plate 102, and the connecting portion can be a connecting groove or a connecting hole or other connecting structure, which is not specifically limited, as long as the connection between the traction member 103 and the clamping jaw 104 can be achieved and the rotation of the clamping jaw 104 is not affected. It can be understood that the clamping jaw 104 can also be driven by other structures, such as a rotary motor, and the output end of the rotary motor can be connected to one or more clamping jaws 104.

[0067] Furthermore, a guide member is provided between the driving plate 102 and the clamping plate 108, and the guide member includes a slide rail (not shown) provided on one of the driving plate 102 and the clamping plate 108, and a slider (not shown) provided on the other of the driving plate 102 and the clamping plate 108. By providing the guide member, the driving plate 102 and the traction member 103 can be guided to move along a preset direction.

[0068] For further information, see Figure 4 The translation assembly includes a translation drive 72 and a translation member 75 connected to the output end of the translation drive 72. The translation member 75 is connected to the second distance adjusting assembly and drives the second distance adjusting assembly to move longitudinally. Preferably, the translation drive 72 is a motor and the translation member 75 is a rack installed on the second distance adjusting assembly. The output end of the translation drive 72 is provided with a gear adapted to the rack. The translation drive 72 drives the gear to rotate, thereby driving the translation member 75 and the second distance adjusting assembly to move longitudinally. More preferably, a guide member is provided between the frame 71 and the second distance adjusting assembly. The guide member includes a fifth slide rail 74 installed on one of the frame 71 and the second distance adjusting assembly, and a fifth slider 73 installed on the other of the frame 71 and the second distance adjusting assembly and adapted to the fifth slide rail 74. The stability of the longitudinal movement of the second distance adjusting assembly is ensured by the guide member.

[0069] For further information, see Figure 7 The second pitch adjusting component includes a pitch adjusting mounting frame 79 and a second pitch adjusting drive 710 mounted on the pitch adjusting mounting frame 79. The output end of the second pitch adjusting drive 710 is connected to the clamping plate 108. The pitch adjusting mounting frame 79 can be slidably arranged on the frame body 71 along the longitudinal direction. The translation member 75 is arranged on the pitch adjusting mounting frame 79. The second pitch adjusting drive 710 is one or a combination of hydraulic cylinders, air cylinders, and screw lifts. Preferably, the second pitch adjusting drive 710 is a air cylinder.

[0070] For further information, see Figure 4 , 5A guide member is provided between the distance adjusting mounting frame 79 and the clamping plate 108, and the guide member includes a fourth slide rail 76 installed on one of the distance adjusting mounting frame 79 and the clamping plate 108, and a fourth slider 77 installed on the other of the distance adjusting mounting frame 79 and the clamping plate 108 and adapted to the fourth slide rail 76. The stability of the clamping plate 108 along the vertical movement is ensured by the guide member.

[0071] like Figure 1 , 10 -12, further, the reinforcement moving device also includes a reinforcement stretching mechanism 4, the reinforcement stretching mechanism 4 includes a reinforcement connecting assembly 43 connected to the main reinforcement, and a reinforcement stretching assembly 42 connected to and driving the reinforcement connecting assembly 43 to move longitudinally; the reinforcement stretching mechanism 4 is located on the side of the movable electrode plate 61 away from the frame 1, and the reinforcement feeding mechanism 7 is located on the side of the movable electrode plate 61 facing the frame 1. The reinforcement feeding mechanism 7 needs to drive the main reinforcement on the frame 1 to pass over the movable electrode plate 61. During the rolling welding process, the reinforcement feeding mechanism 7 will interfere with the external electrode 3. The main reinforcement first passes over the movable electrode plate 61 and is sent to the reinforcement stretching mechanism 4 under the drive of the reinforcement feeding mechanism 7, and then the reinforcement feeding mechanism 7 releases the main reinforcement, and the reinforcement stretching mechanism 4 limits and clamps the main reinforcement. During the welding process, the main reinforcement is driven to move longitudinally by the reinforcement stretching mechanism 4, thereby avoiding the reinforcement feeding mechanism 7 from interfering with the external electrode 3.

[0072] For details, see Figure 1 The reinforcement assembly 42 includes a track 41 and a reinforcement trolley connected to the reinforcement assembly 43. The reinforcement trolley moves along the track 41 to increase stability during reinforcement. Of course, other reinforcement methods can also be used, such as connecting the reinforcement assembly 43 with a wire rope or a cylinder or an oil cylinder, and the reinforcement assembly 43 is driven to move by the wire rope or the cylinder or the oil cylinder. There is no specific limitation here, and it only needs to be able to drive the reinforcement assembly 43 to move.

[0073] See also Fig.11 , 12The connecting bar assembly 43 includes a mounting seat 208 connected to the tension bar assembly 42, two or more clamping plates 433 mounted on the mounting seat 208 and movable toward or away from the center line of the connecting bar assembly 43, and a third distance adjustment assembly connected to and driving the clamping plates 433 to move toward or away from each other. The clamping plates 433 are provided with a clamping jaw 104 for clamping the main bar at one end away from the center line of the connecting bar assembly 43, and the clamping jaw 104 is connected to a clamping jaw 104 driving the clamping jaw 104 to clamp the main bar. In this embodiment, the number of the clamping plates 433 of the connecting bar assembly 43 is two, corresponding to the main bars on the two long sides of the rectangular rigid frame. Specifically, the main reinforcement can be moved longitudinally under the drive of the reinforcement delivery mechanism 7. The main reinforcement first passes over the movable electrode plate 61 and the second reinforcement plate 433 of the reinforcement connecting assembly 43 in sequence under the drive of the reinforcement delivery mechanism 7. Then the second reinforcement plate 433 of the reinforcement delivery mechanism 7 releases the main reinforcement and the reinforcement connecting assembly 43 clamps the main reinforcement. During the welding process, the reinforcement tensioning mechanism 4 drives the main reinforcement to move so that the stirrups can be continuously welded to the main reinforcement. In detail, before the main reinforcement is delivered to the second reinforcement plate 433 of the reinforcement connecting assembly 43, the third distance adjustment assembly drives the second reinforcement plates 433 of the two reinforcement connecting assemblies 43 to move closer to each other, so as to avoid the main reinforcement from sagging at the end under the action of its own gravity during the transfer process, resulting in interference between the main reinforcement and the second reinforcement plate 433 of the reinforcement connecting assembly 43, thereby causing the main reinforcement to be unable to pass over the second reinforcement plate 433 of the reinforcement connecting assembly 43. It is ensured that all main bars can pass through the second clamping plate 433 of the connecting bar assembly 43, and after passing through, they are limitedly clamped by the connecting bar assembly 43, and the main bars move longitudinally under the drive of the tensioning mechanism 4 to complete the welding process. Further, the clamping jaws 104 and the clamping jaw drive in the connecting bar assembly 43 are the same as the clamping jaws 104 and the clamping jaw drive structure in the feeding mechanism 7, of course, they can also be different, without specific restrictions, as long as the clamping jaws 104 can limit the clamping or release of the main bars.

[0074] Further, such as Fig.10 As shown, a guide member is arranged between the driving plate 102 of the connecting bar assembly 43 and the second clamping plate 433, and the guide member includes a third slide rail 107 arranged on one of the driving plate 102 and the second clamping plate 433, and a third slider 101 arranged on the other of the driving plate 102 and the second clamping plate 433. By setting the guide member, the driving plate 102 and the traction member 103 can be guided to move along a preset direction.

[0075] like Figure 15-17As shown, further, the first distance adjustment component includes an adjustment member 206 connected to the movable electrode plate 61 at one end, a guide member arranged between the movable electrode plate 61 and the welding frame 2, and a first distance adjustment drive connected and driving the other end of the adjustment member 206 to deflect so as to drive the movable electrode plate 61 to move along the guide member, and the adjustment member 206 is connected to the first distance adjustment drive at one end and is movably connected to the welding frame 2. Among the two movable electrode plates 61, one movable electrode plate 61 corresponds to one first distance adjustment component, and a mounting seat 208 for mounting two first distance adjustment components is arranged on the welding frame 2, and the two movable electrode plates 61 are movably mounted on the mounting seat 208, and a guide member is arranged between the two movable electrode plates 61 and the mounting seat 208, and the guide member includes a second slide rail 207 installed on one of the movable electrode plate 61 and the mounting seat 208, and a second slider 203 installed on the other of the movable electrode plate 61 and the mounting seat 208 and adapted to the second slide rail 207, and the movable electrode plate 61 can be guided to move along a preset direction by arranging the guide member. The first distance-adjusting drive 201 is a driving member that can output linear motion, such as a cylinder, a hydraulic cylinder, an electric cylinder, an electric push rod, etc., but is not limited to the above examples. The output end of the first distance-adjusting drive 201 is hinged to the adjusting member 206 through the connecting column 202. The output end of the first distance-adjusting drive 201 is extended or retracted by a certain distance to cause the adjusting member 206 to swing, thereby driving the movable electrode plates 61 to approach or move away from each other, that is, one movable electrode plate 61 moves a certain distance in the direction of approaching or moving away from another movable electrode plate 61. Among them, since the adjusting member 206 is connected to the first distance-adjusting drive at one end and is movably connected to the welding frame 2, the adjusting member 206 can not only adjust the position of the movable electrode plate 61, but also support the movable electrode plate 61 during welding, which is helpful to prevent the movable electrode plate 61 from deviating from the preset position under the pressure of the external electrode 3 during the rolling welding process.

[0076] Preferably, see Fig.17 A guide member is provided between the connecting column 202 and the mounting seat 208, and the guide member includes a first slide rail 204 installed on one of the connecting column 202 and the mounting seat 208, and a first slider 205 installed on the other of the connecting column 202 and the mounting seat 208 and adapted to the first slide rail 204. The adjusting member 206 is connected to the first distance adjusting drive and one end is movably connected to the mounting seat 208 through the above-mentioned guide member. One end of the adjusting member 206 is hinged to the connecting column 202, and the other end is hinged to a movable electrode plate 61. By arranging the first slide rail 204 and the first slider 205, the output end of the first distance adjusting drive 201 is prevented from directly bearing the vertical force, which is beneficial to improving the service life of the first distance adjusting drive 201.

[0077] For further information, see Fig.15 , 16The two movable electrode plates 61 are respectively provided with a guiding protrusion at at least one end in the lateral direction. The two guiding protrusions are located on the same side of the two movable electrode plates 61 and are staggered. The guiding protrusions play a role in guiding the movement of the movable electrode plates 61.

[0078] For further information, see Fig.15 , 16 The welding frame 2 is provided with a buffer 64 and a buffer mounting seat 63 between the two movable electrode plates 61. The buffer 64 can prevent the two electrode plates from having a hard collision during the movement. Preferably, the buffer 64 is made of polyurethane.

[0079] For further information, see Fig.17 The welding frame 2 is provided with a limit bolt 210 for limiting the swing amplitude of the adjusting member 206 and a mounting block 209 for mounting the limit bolt 210 on the side of the adjusting member 206 away from the first distance adjustment drive 201. The limit bolt 210 can prevent the adjusting member 206 from swinging too much, causing the two movable electrode plates 61 to deviate from the preset position or collide.

[0080] Further, such as Fig.11 , 12 As shown, the third distance adjustment assembly includes an adjustment member 206 with one end rotatably connected to a second clamping plate 433, a guide member arranged between the second clamping plate 433 and the mounting seat 208, and a third distance adjustment drive connected to and driving the other end of the adjustment member 206 to deflect to drive the second clamping plate 433 to move along the guide member, and the adjustment member 206 is connected to the third distance adjustment drive and one end is movably connected to the mounting seat 208. The structure of the third distance adjusting assembly of the second clamping plate 433 connected to the reinforcement assembly 43 is the same as the structure of the first distance adjusting assembly connected to the movable electrode plate 61. One end of the adjusting member 206 of the third distance adjusting assembly is hinged to the output end of the first distance adjusting drive 201, and the other end is hinged to the second clamping plate 433 of the reinforcement assembly 43, thereby driving the second clamping plate 433 of the reinforcement assembly 43 to move closer to or away from each other, that is, to move in the direction of approaching or moving away from the second clamping plate 433 of another reinforcement assembly 43, wherein the reinforcement mechanism 4 includes a mounting seat 208 for installing two third distance adjusting assemblies, and the reinforcement vehicle is connected to the mounting seat 208 to drive the reinforcement assembly 43 to move longitudinally, and a guide member for guiding the movement of the second clamping plate 433 of the reinforcement assembly 43 is also provided between the second clamping plate 433 of the reinforcement assembly 43 and the mounting seat 208. Of course, the structure of the third distance adjusting component may be different from that of the first distance adjusting component. There is no limitation on the specific structure of the third distance adjusting component and the first distance adjusting component, as long as it can drive the two movable electrode plates 61 or the two rib connecting assemblies 43 to move toward and away from each other.

[0081] like Fig.13 , 14As shown in Figures 18, further, the rigid frame forming equipment for construction also includes a limiting device 8 arranged on the welding frame 2 near the active electrode plate 61, and the limiting device 8 includes two rib limiting plates 81 installed on the welding frame 2. The outer side of the rib limiting plate 81 is provided with a limiting member 82 for limiting the approximate position of the main rib, and the limiting member 82 is connected to a limiting drive for driving the limiting member to limit the main rib. The limiting device 8 limits the radial position of the main rib, and the main rib can pass through the limiting device longitudinally. In this embodiment, the number of the rib limiting plates 81 is two, corresponding to the main ribs on the two long sides of the rectangular rigid frame respectively. During the welding process, the rib limiting plate 81 and the limiting member 82 jointly form a limiting space for limiting the main rib, and the limiting space corresponds to the groove on the active electrode plate 61 for accommodating the main rib in the longitudinal direction. The main rib is limited by the above-mentioned limiting space to prevent the main rib from being separated from the groove on the active electrode plate 61 for accommodating it during the welding process, ensuring that all the main ribs can form a good weld with the stirrups, thereby improving the qualified rate of the formed rigid frame. Furthermore, the limit member 82 has the same structure as the clamp 104, and the limit drive is the same as the clamp drive structure of the reinforcement feeding mechanism 7. Of course, they can also be different, without specific restrictions, as long as the limit clamping or loosening of the main reinforcement can be achieved. The limit device 8 is installed on the welding frame 2 and there is a certain length of interval between the frame 1. At this time, the cross-sectional size of the limit space formed by the reinforcement plate 81 and the limit member 82 is larger than the cross-sectional area of ​​the main reinforcement. Preferably, the cross-sectional size of the limit space is 4 times the cross-sectional area of ​​the main reinforcement. At this time, the end of the main reinforcement can smoothly pass through the limit plate 81 even if it bends under the influence of its own weight. Alternatively, the limit device 8 is similar in structure to the clamp assembly 43, that is, the limit plate 81 can be retracted to the center of the limit device 8 to avoid the main reinforcement. The avoidance structure has been described in detail in the clamp assembly 43, and the avoidance structure of the limit device 8 is not described in detail here. Preferably, the limiting device 8 is installed on the welding frame 2 and there is a certain length of interval between the frame 1, and the cross-sectional area of ​​the limiting space is 4 times the cross-sectional area of ​​the main reinforcement.

[0082] like Figure 5-7As shown in 10-14 and 18, further, the rib plate 1 and / or the rib plate 2 433 and / or the rib limiting plate 81 are provided with a plurality of first grooves for placing the main ribs; the clamping jaws 104 and the first grooves form a limited clamping for the main ribs, and the first grooves can form a preliminary limit for the main ribs to prevent the main ribs from shifting and escaping from the limited clamping range during the clamping process, thereby improving the clamping effect. There are two specific situations for the clamping jaws 104 and the first grooves of the rib plate 2 433 or the rib plate 2 433 to cooperate with the main ribs to clamp the main ribs: first, the clamping jaws 104 and the first grooves can clamp the outer wall of the main ribs; second, the clamping jaws 104 and the first grooves cooperate to limit the main ribs between the two, and the two can slide relative to the main ribs and abut against the swaging head or sleeve. Of course, other limited clamping methods can also be used. There is no specific limitation on the specific method of the clamping jaws 104 and the first grooves cooperating to clamp the main ribs, and it is sufficient to achieve the main ribs following the movement after limited clamping. The first groove may be in an arc shape, a triangle shape, a trapezoid shape, etc., and the specific shape of the first groove is not limited here.

[0083] Preferably, see Fig.13 Limiting members 82 are provided on both longitudinal sides of the rib limiting plate 81, and the limiting members 82 on the same side are driven together by the limiting drive of that side. The limiting members 82 on both sides of the rib limiting plate 81 and the first groove on the rib limiting plate 81 jointly form a limiting space for the main rib. The first groove can form a preliminary limiting position for the main rib, thereby preventing the main rib from shifting and escaping from the limiting space during the limiting process, thereby improving the limiting effect.

[0084] Further, such as Figure 1 , 2 As shown, a discharging assembly is provided on the frame 1, and the discharging assembly includes a discharging rod 11 rotatably mounted on the frame 1, a discharging drive 12 driving the discharging rod 11 to rotate, and the discharging assembly also includes a buffer rod 13 and a buffer drive 14 driving the buffer rod 13 to rise; the outer circumference of the discharging rod 11 and / or the buffer rod 13 are provided with spiral wings, and the main bars are transported to the discharging rod 11 from one side in the lateral direction one by one. The discharging rod 11 rotates under the action of the discharging drive 12, thereby driving the main bars thereon to move in the lateral direction on the discharging rod 11 to realize the discharging of the main bars. In this embodiment, the discharging rod 11 is provided with two rows, corresponding to the main bars on the two long sides of the rectangular rigid frame. Furthermore, a cache rod 13 is provided at one end of the discharge rod 11 away from the main reinforcement loading station. After the main reinforcements are fully loaded on the discharge rod 11, the cache rod 13 can rise under the action of the cache drive 14 to leave a certain area at one end of the discharge rod 11 away from the main reinforcement loading station, so that the discharge rod 11 can continue to discharge the main reinforcements, thereby improving work efficiency.

[0085] Further, such as Figure 1 , 3As shown in , 9, the outer electrode 3 includes a rotating plate 36 rotatably installed on the welding frame 2, a welding drive 31 for driving the rotating plate 36 to rotate, a welding arm 38 rotatably installed on the rotating plate 36, and a clamping drive 39 installed on the rotating plate 36. A welding wheel 37 is provided at one end of the welding arm 38, and the other end of the welding arm 38 is hinged to the output end of the clamping drive 39. The welding wheel 37 is provided with a second groove for the main reinforcement to pass through. During the welding process, the welding drive 31 drives the rotating plate 36 to rotate. Preferably, the welding drive 31 drives the rotating plate 36 to rotate through the first chain 32, and the output end of the clamping drive 39 extends to rotate the welding arm 38, so that the welding wheel 37 on the welding arm 38 is pressed against the movable electrode plate 61. The welding wheel 37 is provided with a second groove for the stirrup to pass through. Under the action of the welding wheel 37, the stirrup is pressed against the main reinforcement on the movable electrode plate 61, so that an effective welding is formed between the main reinforcement and the stirrup.

[0086] Further, such as Figure 8 , 9 As shown, the outer electrode 3 also includes an arc-shaped conductive plate 33 mounted on the welding frame 2, a plurality of mounting members 35 spaced apart on the arc-shaped conductive plate 33, a carbon brush 34 mounted on the mounting member 35, and a copper ring 311 mounted on the rotating plate 36 and abutting against the carbon brush 34. An elastic member 313 is arranged between the mounting member 35 and the carbon brush 34. The carbon brush 34 is connected to the arc-shaped conductive plate 33 through a conductive member. A copper block 312 is installed on the copper ring 311, and the copper block 312 is electrically connected to the welding wheel 37. The external current is introduced from the arc-shaped conductive plate 33 and flows through The carbon brush 34 is used to transfer the current to the copper ring 311. The elastic member 313 makes the carbon brush 34 abut against the copper ring 311 to ensure that the current can be transferred from the carbon brush 34 to the copper ring 311. The copper ring 311 rotates synchronously with the welding arm 38. The copper ring 311 is electrically connected to the copper block 312, and the copper block 312 is connected to the welding wheel 37 through a braided wire, so that the current is transferred to the welding wheel 37. By arranging the arc-shaped conductive plate 33, a plurality of mounting parts 35 and the carbon brush 34, it is ensured that during the rotation of the welding arm 38, the welding wheel 37 can always be energized uninterruptedly.

[0087] Further, such as Fig. 9As shown, the welding arm 38 is provided with a rotating shaft 310, and a fourth distance adjustment component installed on the rotating plate 36 is provided at one end of the rotating shaft 310 close to the rotating plate 36, and the rotating plate 36 is provided with a fifth distance adjustment component, and the pressing drive 39 is installed on the rotating plate 36 through the fifth distance adjustment component. In order to make the movement trajectory of the welding wheel 37 adapt to the change of the outer contour shape formed by the two or more movable electrode plates 61, the position of the rotating shaft 310 of the welding arm 38 is adjusted by the fourth distance adjustment component to change the turning radius of the welding wheel 37 to adapt to the outer contour shape of the movable electrode plate 61. After the fourth distance adjustment component adjusts the position of the rotating shaft 310 of the welding arm 38, further, in order to make the movement trajectory of the welding wheel 37 change adaptively with the change of the outer contour shape of the rigid frame, the pressing drive 39 can still apply a constant pressure to the welding arm 38, and the fifth distance adjustment component adjusts the position of the pressing drive 39 to adapt to the welding arm 38 with the position of the rotating shaft 310 adjusted. The fourth distance adjustment component and the fifth distance adjustment component can achieve the change of the position of the rotating shaft 310 or the pressing drive 39 of the driving welding arm 38, and the specific structure thereof is not limited. Here, a preferred structure of the fourth distance adjustment component is provided, the fourth distance adjustment component includes an adjustment box, an adjustment block movably arranged in the adjustment box, the adjustment box is provided with a guide rod penetrating the adjustment block, and a fourth adjustment drive driving the adjustment block to move, the rotating shaft 310 is arranged in the adjustment block, and the fourth adjustment drive can be one or a combination of a cylinder, a hydraulic cylinder, and an electric push rod. Of course, the fourth adjustment drive can also be a power source for outputting a rotating force. When the fourth adjustment drive is a power source for outputting a rotating force, the guide rod is provided with an external thread, and the adjustment block is provided with an internal thread adapted to the external thread of the guide rod. The structure of the fifth distance adjustment component is the same as that of the fourth adjustment drive. Of course, the structures of the fifth distance adjustment component and the fourth distance adjustment component may also be different. The specific structures of the fifth distance adjustment component and the fourth distance adjustment component are not limited, as long as the rotating shaft 310 or the pressing drive 39 of the driving welding wall can be driven to move.

[0088] Further, such as Figure 1 , 3 As shown in , 15, 19-21, the outer electrode 3 also includes a feeding mechanism 5, which includes a material tray 52 rotatably mounted on the frame 1, a feeding drive 51 driving the material tray 52 to rotate, and a guide plate 54 mounted on the rotating plate 36. A plurality of guide rings 541 are arranged at intervals on the guide plate 54, and the guide rings 541 form a guide space for the stirrups to pass through; the feeding drive 51 drives the material tray 52 to rotate so as to rotate the stirrups out of the material tray 52. ​​Preferably, the feeding drive 51 drives the material tray 52 to rotate through the second chain 53. The stirrups are guided to extend through the guide ring 541 on the guide plate 54, and then extend between the welding wheel 37 and the movable electrode plate 61 after bypassing the second groove on the welding wheel 37, and contact with the main reinforcement to form a welding point. A conductive plate 62 is arranged on the movable electrode plate 61, and the conductive plate 62 is connected to an external power source through a braided wire to power the movable electrode plate 61.

[0089] Further, such as Fig. 9 As shown, the welding arm 38 is provided with a mounting frame, a guide wheel 314 rotatably provided on the mounting frame, and the guide wheel 314 is provided with a third groove for the stirrup to pass through. After the stirrup extends from the guide ring 541 on the guide plate 54, it passes through the third groove on the guide wheel 314 and then goes around to the second groove on the welding wheel 37, thereby improving the stability of the stirrup feeding.

[0090] Further, such as Figure 1 , 3 As shown in , 11 and 12, the welding frame 2 is provided with an air storage cylinder 21, an integrated control valve 432 is provided on the mounting seat 208 of the third pitch adjustment component, and an air pipe channel 431 through which the air supply pipe passes is provided on the mounting seat 208 of the third pitch adjustment component.

It can be understood that, in order to facilitate the arrangement of the air pipe, the air pipe channel 431 can be opened on each component of the equipment according to the actual working conditions, and the specific opening of the air pipe channel 431 is not limited here.

[0091] Embodiment 2

[0092] The same parts in this embodiment as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0093] Compared with the first embodiment, the rigid frame forming equipment for construction provided in this embodiment has the following different structural designs:

[0094] The number of the movable electrode plates 61 or the second rib plates 433 of the connecting rib assembly 43 can be three or more than four. The specific number and arrangement of the movable electrode plates 61 or the second rib plates 433 of the connecting rib assembly 43 can be selected according to the cross-sectional outer contour shape of the rigid skeleton. For example, more than three movable electrode plates 61 or the second rib plates 433 of the connecting rib assembly 43 are arranged in a polygonal or circular shape, etc., and there is no specific restriction. The number of the first distance adjustment assembly or the third distance adjustment assembly can also be selected according to actual needs. The first distance adjustment assembly can drive more than three movable electrode plates 61 to move at the same time, or each first distance adjustment assembly can drive one movable electrode plate 61 to move; the third distance adjustment assembly and the second rib plates 433 are the same, and can correspond to each other individually or in multiple to one. When there are multiple first distance adjustment assemblies or third distance adjustment assemblies, the structures of the multiple first distance adjustment assemblies or third distance adjustment assemblies can be exactly the same or different, depending on the actual situation.

[0095] Specifically, there must be gaps between the main bars of the rigid frame, and the gaps between the main bars of the rigid frame can provide retraction space for the movable electrode plate 61 or the second clamping plate 433 of the connecting bar assembly 43. Before the movable electrode plate 61 or the second clamping plate 433 of the connecting bar assembly 43 is required to clamp the main bar, each adjustment component controls the corresponding movable electrode plate 61 or the second clamping plate 433 of the connecting bar assembly 43 to move and shrink, that is, the range occupied by the central electrode 6 or the connecting bar assembly 43 is reduced to avoid the main bar, so as to avoid the main bar end from interfering with the movable electrode plate 61 or the second clamping plate 433 of the connecting bar assembly 43 and being unable to cross due to the bending of the main bar due to its own weight or the influence of the nut when the bar moving device moves the main bar to the traction device.

[0096] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
