Description

Technical Field

[0001] The present invention relates to the technical field of steel cage processing equipment, and particularly relates to a welding device for the main reinforcement bars of a steel cage. Background Art

[0002] With the development of the country's construction cause, great progress has been made in the construction field and road construction. During the foundation construction of projects, steel cages are more and more widely used. When constructing bridges, culverts or high-rise buildings, pile driving is carried out according to requirements. After the hole depth reaches the requirements, the steel cage is lowered into the pile hole, and then the conduit is inserted for concrete pouring. The steel cage plays a role in restraining the pile body concrete, enabling it to bear a certain axial tensile force.

[0003] The steel cage mainly includes three parts: main reinforcement bars, stirrups and spiral reinforcement bars. The main reinforcement bars are arranged in parallel at intervals and surround the stirrups. The main reinforcement bars and the stirrups are connected by welding. In the prior art, manual welding is usually used for welding the main reinforcement bars and the stirrups. Due to the large number of welding points, the labor intensity is relatively high. If the worker is slightly negligent, problems such as insecure welding points and burning of the main reinforcement bars will occur. The welding quality is unstable and the welding efficiency is not high. There are also some that use steel cage processing equipment for welding, but the degree of automation is not high, and automatic welding at the intersection of the main reinforcement bars and the stirrups cannot be achieved. Summary of the Invention

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0048] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", and "left" are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] The steel reinforcement cage is a commonly used building material in bridge and culvert or high-rise building construction, mainly composed of multiple annular reinforcing bars and multiple straight main bars. During processing, the annular reinforcing bars are first fixed at intervals, then the main bars are transported to the positions of the reinforcing bars, and then the main bars and the reinforcing bars are welded and connected.

[0050] Such as Figure 1 and Figure 2As shown in the figure, in order to achieve rapid welding of the main reinforcement bars 500 and the reinforcing bars 600, the present embodiment provides a welding device for the main reinforcement bars of a steel reinforcement cage, which includes a material receiving mechanism 100, an alignment mechanism 200, and a welding mechanism 300. Multiple sets of the material receiving mechanism 100 are provided and arranged at intervals, and multiple sets of the material receiving mechanism 100 jointly receive a main reinforcement bar 500. The alignment mechanism 200 is arranged outside the multiple sets of the material receiving mechanism 100 and can align the ends of multiple main reinforcement bars 500. Multiple sets of the welding mechanism 300 are provided, and the multiple sets of the welding mechanism 300 are arranged at intervals with the material receiving mechanism 100. The welding mechanism 300 includes a clamping component 310 and a welding component 320. The clamping component 310 can move along the first direction and the second direction perpendicular to each other. The clamping component 310 can receive and clamp the main reinforcement bar 500 on the material receiving mechanism 100, and can move the main reinforcement bar 500 to the position of the reinforcing bar 600, and form an intersection point between the main reinforcement bar 500 and the reinforcing bar 600. The welding component 320 can detect the intersection point and weld the intersection point.

[0051] In this embodiment, as Figure 1 shown, six sets of the welding mechanism 300 are provided. A set of the material receiving mechanism 100 is arranged on the right side of each set of the welding mechanism 300. The alignment mechanism 200 is arranged on the right side of the rightmost material receiving mechanism 100. The six sets of the material receiving mechanism 100 are arranged at intervals to jointly support the main reinforcement bar 500. The main reinforcement bar 500 is placed on the material receiving mechanism 100 manually or by an automated device. The ends of the main reinforcement bar 500 are aligned by the alignment mechanism 200. The clamping component 310 of the welding mechanism 300 moves to the position of the main reinforcement bar 500. As Figure 2 shown, the clamping component 310 clamps the main reinforcement bar 500, moves the main reinforcement bar 500 to the position of the reinforcing bar 600 and forms an intersection point with the main reinforcement bar 500. After the welding component 320 detects the intersection point, it welds the intersection point, thereby achieving rapid and precise welding of the main reinforcement bar 500 and the reinforcing bar 600. The degree of automation is high, manual operation is not required, the welding efficiency is high, and it is beneficial to ensure the stability of the welding quality. In actual production, the number of sets of the welding mechanism 300 and the material receiving mechanism 100 can be reasonably set according to the length of the main reinforcement bar 500. It can be more or less than six sets, as long as the stable reception and rapid welding of the entire main reinforcement bar 500 can be achieved, and no limitation is made here.

[0052] Preferably, as Figure 1As shown, the bottoms of the above-mentioned welding mechanism 300, alignment mechanism 200, and material receiving mechanism 100 are fixed to the bottom beam 400. The bottom beam 400 is a flat plate-like structure, providing a reference plane for the installation of the welding mechanism 300, alignment mechanism 200, and material receiving mechanism 100. The installation is relatively convenient, and the overall position can be adjusted, making it more flexible during actual work. Preferably, the welding mechanism 300, alignment mechanism 200, and material receiving mechanism 100 are bolted to the bottom beam 400, which is relatively convenient for disassembly and assembly. It can be understood that other connection methods such as welding can also be used to firmly connect the welding mechanism 300, alignment mechanism 200, and material receiving mechanism 100 to the bottom beam 400, and the connection method is not limited here.

[0053] The following will describe the specific structure of the material receiving mechanism 100 in conjunction with Figure 3 the following.

[0054] As Figure 3 shown, the material receiving mechanism 100 includes a support frame 110 and a material receiving part 120. The material receiving part 120 is arranged on the upper side of the support frame 110. A groove 121 is provided on the material receiving part 120. The main reinforcement 500 is limited within the groove 121 to prevent the main reinforcement 500 from sliding and disengaging from the material receiving mechanism 100, thereby ensuring the stability of the material receiving mechanism 100 in carrying the main reinforcement 500.

[0055] Preferably, as Figure 3 shown, one side wall of the groove 121 is higher than the other side. During installation, the lower side wall is oriented towards the stiffener 600. The clamping assembly 310 can slightly lift upwards to move the main reinforcement 500 out of the groove 121, which is beneficial for quickly moving the main reinforcement 500 to the position of the stiffener 600.

[0056] Furthermore, after the main reinforcement 500 is placed on the material receiving mechanism 100, it is necessary to move the main reinforcement 500 to align the ends of the main reinforcement 500. To facilitate the movement of the main reinforcement 500, as Figure 3As shown, the material receiving mechanism 100 further includes a bearing 130 and a guide wheel 140. The bearing 130 is arranged on the upper side of the support frame 110 and is located on one side of the material receiving portion 120 along the extending direction of the main reinforcement 500. Both ends of the guide wheel 140 are rotatably connected to the bearing 130. A guide groove 141 is arranged along the circumferential direction of the guide wheel 140. The guide groove 141 and the groove 121 on the material receiving portion 120 are located on the same straight line, and the bottom height of the guide groove 141 is slightly higher than the bottom height of the groove 121 on the material receiving portion 120. The main reinforcement 500 is limited within the guide groove 141, and the bottom of the main reinforcement 500 is in direct contact with the bottom of the guide groove 141. When the main reinforcement 500 is pulled, the guide wheel 140 rotates under force, which is equivalent to the rolling movement of the main reinforcement 500 and is relatively labor-saving. Preferably, the bearing 130 is a pedestal bearing, and the bearing pedestal is connected to the support frame 110. In this embodiment, the bearing pedestal and the support frame 110 are connected by welding, which can save installation space; in other embodiments, bolt connection can also be used, which is convenient for disassembly and assembly. The connection method can be reasonably selected according to the installation environment without limitation.

[0057] The cross-section of the support frame 110 can be cylindrical or rectangular, as long as it can realize the stable installation of the material receiving portion 120 and the bearing 130 and the stable bearing of the main reinforcement 500, and there is no limitation here.

[0058] Next, in conjunction with Figure 4 the specific structure of the alignment mechanism 200 will be described.

[0059] After the main reinforcement 500 is placed on the material receiving mechanism 100, according to the production requirements of the steel cage, the ends of the main reinforcement 500 need to be aligned as a whole or staggered and then welded.

[0060] As Figure 4 shown, the alignment mechanism 200 includes a chassis 210, an alignment baffle 220 and a sliding plate 230. The alignment baffle 220 is arranged on the upper side of the chassis 210 along the direction perpendicular to the main reinforcement 500 on the material receiving mechanism 100. One end of the main reinforcement 500 can abut against the alignment baffle 220. The sliding plate 230 and the alignment baffle 220 are arranged on the chassis 210 at intervals. The sliding plate 230 is arranged between the alignment baffle 220 and the material receiving mechanism 100. The sliding plate 230 can slide along the first direction so that the main reinforcement 500 can abut against the sliding plate 230 or the sliding plate 230 can avoid the main reinforcement 500. The distance between the sliding plate 230 and the alignment baffle 220 is determined according to the distance that the ends of the adjacent main reinforcements 500 of the steel cage need to be staggered. For example, if the distance that the ends of the adjacent main reinforcements 500 of the steel cage need to be staggered is a, then the distance between the sliding plate 230 and the alignment baffle 220 is also set to a.

[0061] Preferably, the alignment baffle 220 is an inverted T shape, and bolt holes are arranged on the lower plate and are connected to the chassis 210 by bolts.

[0062] When the ends of all the main reinforcement bars 500 need to be aligned integrally, all the main reinforcement bars 500 can be made to abut against the sliding plate 230 or the alignment baffle 220 one by one so as to align the ends of the main reinforcement bars 500. When adjusting the alignment of the main reinforcement bars 500 through the alignment baffle 220, the sliding plate 230 is made to slide downward so that the main reinforcement bars 500 can pass through the position where the sliding plate 230 is located and reach the alignment baffle 220. When the ends of the main reinforcement bars 500 need to be stagger-aligned, for example, if the ends of adjacent main reinforcement bars 500 are staggered by a distance a in the length direction of the main reinforcement bars 500, at this time, the distance between the sliding plate 230 and the alignment baffle 220 is set to be a. First, the sliding plate 230 is slid downward, and the main reinforcement bar 500 is pulled to make it abut against the alignment baffle 220. After the welding of this main reinforcement bar 500 is completed, the next main reinforcement bar 500 abuts against the sliding plate 230 for alignment. At this time, the sliding plate 230 is slid upward, and the main reinforcement bar 500 is pulled to make it abut against the sliding plate 230. In this way, the welding of all the main reinforcement bars 500 is completed in a cycle.

[0063] Furthermore, as Figure 4 shown, the alignment mechanism 200 further includes an alignment cylinder 240. The alignment cylinder 240 is arranged on the lower side of the chassis 210. The sliding plate 230 is connected to the output end of the alignment cylinder 240, and the alignment cylinder 240 can drive the sliding plate 230 to slide in the first direction. The cylinder has a simple structure and stable operation, and can drive the sliding plate 230 to slide stably. In this embodiment, the alignment cylinder 240 is connected to the chassis 210 through bolts.

[0064] Preferably, as Figure 4 shown, a chute seat 250 is sleeved outside the sliding plate 230. The bottom of the chute seat 250 is welded to the chassis 210, and the chute seat 250 makes the sliding of the sliding plate 230 more stable.

[0065] Next, the specific structure of the welding mechanism 300 will be described in conjunction with Figure 5 and Figure 6 .

[0066] As Figure 5 and Figure 6 shown, the welding mechanism 300 includes a clamping assembly 310 and a welding assembly 320. The clamping assembly 310 includes a supporting member 311 and a clamping member 312. The supporting member 311 is used to support the main reinforcement bar 500, and the clamping member 312 can clamp and fix the main reinforcement bar 500 on the supporting member 311. The front end of the supporting member 311 is bent upward. When clamping the main reinforcement bar 500, the clamping member 312 presses the main reinforcement bar 500 against the upwardly bent part of the supporting member 311 to form a clamping force to fix the main reinforcement bar 500.

[0067] Furthermore, as Figure 5As shown in the figure, the welding mechanism 300 further includes a mounting frame assembly 330, a lifting cylinder 340, a power structure 350, and a sliding assembly 360. The lifting cylinder 340 is disposed on the mounting frame assembly 330. One end of the power structure 350 is connected to the output end of the lifting cylinder 340, and the lifting cylinder 340 can drive the power structure 350 to move in the first direction. The sliding assembly 360 is slidably disposed on the power structure 350, and the power structure 350 can drive the sliding assembly 360 to slide in the second direction. The supporting member 311 is disposed on the sliding assembly 360. The lifting cylinder 340 and the power structure 350 drive the supporting member 311 to move in the first direction and the second direction, so that the supporting member 311 can move to the position of the material receiving mechanism 100, thereby moving the main reinforcement 500 from the material receiving mechanism 100 to the supporting member 311.

[0068] Specifically, as Figure 5 shown, the mounting frame assembly 330 includes a mounting base 331. The bottom of the mounting base 331 is fixed to the bottom beam 400 by bolts. The mounting base 331 has a receiving space, and the lifting cylinder 340 is disposed in the receiving space. A through hole is provided on the upper end surface of the mounting base 331, and the lifting cylinder 340 can pass through the through hole. A cylinder fixing plate 332 is connected above the mounting base 331. After passing through the through hole, the lifting cylinder 340 is fixed to the cylinder fixing plate 332. A through hole is also provided on the cylinder fixing plate 332, and the output end of the cylinder passes through the through hole.

[0069] Further, as Figure 5 shown, the mounting frame assembly 330 further includes two guide posts 333 and a gland 334. The two guide posts 333 are arranged on the cylinder fixing plate 332 at intervals in the second direction. The upper ends of the two guide posts 333 are connected by the gland 334. Corresponding through holes are provided on the gland 334. The gland 334 is sleeved on the guide posts 333 through the through holes and fastened by bolts. The setting of the gland 334 connects the two guide posts 333, making the structure of the guide posts 333 more stable.

[0070] Further, as Figure 5 shown, guide bushings 335 are sleeved on the outer sides of the two guide posts 333. The guide bushings 335 can slide up and down along the guide posts 333. A rib plate 336 is provided between the two guide bushings 335. Both ends of the rib plate 336 are welded to the two guide posts 333, and the connection is relatively firm. Preferably, two rib plates 336 are provided, and the two rib plates 336 are arranged at intervals between the two guide posts 333. The lower rib plate 336 is connected to the output end of the lifting cylinder 340, and the lifting cylinder 340 can drive the rib plate 336 to move in the first direction.

[0071] Further, as Figure 5As shown, the mounting bracket assembly 330 further includes two vertical plates 337. The two vertical plates 337 are respectively arranged on both sides of the rib plate 336 along the second direction. The vertical plates 337 are connected to the rib plate 336 by bolts, which is relatively convenient for connection and facilitates disassembly and assembly. Of course, welding can also be used for connection, making the connection more stable.

[0072] Further, as Figure 5 shown, the upper end of the vertical plate 337 is connected to the power structure 350 by bolts. When the lifting cylinder 340 drives the rib plate 336 to move along the first direction, it will drive the vertical plate 337 to move, thereby driving the power structure 350 to move along the first direction.

[0073] Further, as Figure 5 shown, the welding mechanism 300 further includes a first moving cylinder 371. The first moving cylinder 371 is arranged on the sliding assembly 360. The clamping member 312 is connected to the output end of the first moving cylinder 371. The first moving cylinder 371 can drive the clamping member 312 to move along the second direction so that the clamping member 312 clamps the main rib 500 on the supporting member 311.

[0074] Specifically, as Figure 5 shown, the output end of the first moving cylinder 371 is connected with a top plate 380. The clamping member 312 is fixed on the top plate 380. The clamping member 312 is connected to the top plate 380 by welding or bolts. The clamping member 312 includes a connecting plate 3121 and two clamping plates 3122. The connecting plate 3121 is attached to the top plate 380. The two clamping plates 3122 are arranged at both ends of the connecting plate 3121. The clamping plates 3122 extend perpendicular to the connecting plate 3121 along the second direction. The first moving cylinder 371 drives the top plate 380 to move, driving the clamping plates 3122 to approach the supporting member 311, thereby clamping and fixing the main rib 500.

[0075] Further, as Figure 6 shown, the output end of the first moving cylinder 371 is further provided with a second moving cylinder 372. The second moving cylinder 372 expands and contracts along the third direction, and the third direction is perpendicular to the first direction and the second direction. The output end of the second moving cylinder 372 is provided with a detection plate 321. The second moving cylinder 372 can drive the detection plate 321 to move along the third direction to detect the position of the reinforcing rib 600. The front end of the detection plate 321 is longer than the clamping plate 3122 (refer to Figure 5 ), to ensure that the detection plate 321 can contact the reinforcing rib 600.

[0076] Specifically, as Figure 6 shown, the two ends of the connecting plate 3121 are provided with second cylinder fixing plates 390. The second moving cylinder 372 is arranged on the second cylinder fixing plates 390.

[0078] Specifically, as Figure 5 and Figure 6 shown, the rotating shaft seat 322 is provided at one end of the detection board 321 close to the first moving cylinder 371. A horizontally placed first plate 325 is provided on the upper side of the rotating shaft seat 322, and the first plate 325 is welded to the rotating shaft seat 322. The adjustment seat 323 includes a vertical adjustment seat 3231 and a horizontal adjustment seat 3232.

A second plate 326 is provided on the lower side of the vertical adjustment seat 3231, and the vertical adjustment seat 3231 is welded to the second plate 326. The second plate 326 has the same shape as the first plate 325 and is connected together by bolts.

[0079] Working process:

[0080] During operation, in the previous process, the main reinforcement bars 500 are fed to the receiving mechanism 100, and then the main reinforcement bars 500 are manually dragged to the alignment mechanism 200. According to the processing requirements of the steel cage, it is usually required that the ends of adjacent main reinforcement bars 500 are staggered by 1 m. At this time, the alignment cylinder 240 is retracted, and the first main reinforcement bar 500 abuts against the alignment baffle 220. When aligning the next main reinforcement bar 500, the alignment cylinder 240 is extended in advance, and the main reinforcement bar 500 abuts against the sliding plate 230. According to the processing requirements of the steel cage, when it is necessary to align the ends of all the main reinforcement bars 500, the alignment cylinder 240 can be extended, and all the main reinforcement bars 500 abut against the sliding plate 230; or the alignment cylinder 240 can be retracted, and all the main reinforcement bars 500 abut against the alignment baffle 220. Then, the lifting cylinder 340 in the welding mechanism 300 extends, driving the clamping assembly 310 to rise to the required position. At this time, the first moving cylinder 371 extends, and the main reinforcement bar 500 on the receiving mechanism 100 is clamped by the clamping member 312 and the supporting member 311. The power structure 350 is started, driving the sliding assembly 360, the main reinforcement bar 500 and the welding assembly 320 to move forward together. When the main reinforcement bar 500 contacts the stirrup 600, the power structure 350 stops, and the second moving cylinder 372 drives the welding assembly 320 to move. When the detection plate 321 touches the stirrup 600, the welding torch 324 starts automatic welding. During the welding process, the position of the welding torch 324 can be adjusted by the adjustment seat 323 and the rotating shaft seat 322. After welding is completed, the entire mechanism returns to its original position to continue welding the next main reinforcement bar 500.
