Description

Technical Field

[0001] This utility model belongs to the technical field of rebar cage winding equipment, and specifically relates to a spiral rebar winding equipment for utility pole rebar cages. Background Technology

[0002] The processing of rebar cages is completed in the rebar cage forming area. While mature rebar processing equipment such as fixed-length cutting machines and fully automatic coiling machines are available on the market, the rebar cage winding process remains manual and cannot be automated. Traditional rebar cage fabrication uses electric hoists for tensioning. The operation involves fixing one end of the rebar cage to a steel frame column and connecting the other end to the electric hoist hook. The hoist is manually operated to tighten the rebar cage to a tension deemed appropriate by the operator. Then, manual marking and arrangement of the spiral reinforcement are required. A roll of spiral reinforcement is then unrolled and tied at the manually measured intervals. Because this process relies on manual labor, problems such as uneven spiral reinforcement spacing, inaccurate winding counts, high worker workload, and impact on the mechanical properties of the pole are common. Furthermore, the entire tensioning process lacks tension force monitoring, relying entirely on worker experience. Fluctuations in tension force during production result in loose and uneven winding of the spiral reinforcement, compromising quality. Additionally, excessive tensioning pressure from the electric hoist poses a safety hazard.

[0003] Currently available steel cage winding machines have simple structures and controls, low levels of automation, and do not meet quality and safety requirements. Therefore, there is an urgent need to develop a high-efficiency and safe spiral winding equipment for utility pole steel cages. Utility Model Content

[0031] Example

[0032] like Figs. 1 to 4As shown, a spiral reinforcement winding device for a utility pole reinforcement cage includes a main reinforcement straightening device 200 for driven rotation and tensioning of one end of the reinforcement cage 100. The other end of the reinforcement cage 100 is mounted on an active rotation force measuring device 300. The active rotation force measuring device 300 serves as the active fixed end, and the main reinforcement straightening device 200, which serves as the driven end, tightens (stretches) the reinforcement cage 100 to ensure uniform winding of the spiral reinforcement and improve the production quality of the reinforcement cage 100.

[0033] Furthermore, a spiral bar winding device 400 for winding spiral bars on the side of the reinforcing cage 100 is also provided. The spiral bar winding device 400 moves slowly along the axial direction of the reinforcing cage 100 and conveys the spiral bar. Under the synchronous rotation of the main reinforcing bar straightening device 200 and the active rotation force measuring device 300, the tightened reinforcing cage 100 rotates at a uniform speed so that the spiral bar can be evenly wound on the reinforcing cage 100.

[0034] Preferably, the main reinforcement straightening device 200 includes a mounting base 210, a tensioning drive mechanism 220, a tensioning screw protection mechanism 230, a guide rail base 240, and a rotary tensioning mechanism 250. The mounting base 210 is erected in the working area. The tensioning drive mechanism 220 is mounted on the mounting base 210, and its output end is connected to the rotary tensioning mechanism 250. The guide rail base 240 is installed in front of the mounting base 210, and the rotary tensioning mechanism 250 is slidably mounted on the guide rail base 240. Driving the tensioning drive mechanism 220 causes the rotary tensioning mechanism 250 to slide on the guide rail base 240 to tighten the reinforcement cage 100. The tensioning screw protection mechanism 230 is located behind the mounting base 210 and is used to protect the tensioning drive mechanism 220. During the fabrication of the reinforcing cage, the reinforcing cage 100 can rotate while its tension is measured by the active rotation force measuring device 300 to ensure constant tension. It is worth mentioning that the maximum tension that the main reinforcing bar straightening device 200 can output is 20T.

[0035] Furthermore, it also includes a control system. The active rotating force measuring device 300, the spiral bar winding device 400, the tensioning drive mechanism 220, and the rotating tensioning mechanism 250 are all electrically connected to the control system. Through the control of the control system, the smooth and coordinated operation of the active rotating force measuring device 300, the spiral bar winding device 400, the tensioning drive mechanism 220, and the rotating tensioning mechanism 250 is ensured. It is worth mentioning that the control system uses a PLC.

[0036] Furthermore, the active rotation force measuring device 300 is equipped with a tension force detection mechanism, which can detect the tension force on the rebar cage 100 in real time while the main reinforcement straightening device 200 pulls the rebar cage 100. This avoids excessive tension force on the rebar cage 100, which could lead to safety accidents, and also prevents insufficient tension force on the rebar cage 100, which could affect the production quality of the rebar cage 100. When the tension force on the rebar cage 100 reaches a limit value (set value), the control system controls the main reinforcement straightening device 200 to stop pulling the rebar cage 100.

[0037] In some preferred embodiments, the tensioning drive mechanism 220 includes a T-shaped nut, a tensioning elongation T-shaped screw 221, a tensioning elongation motor 222, a drive gear, and a driven gear. The T-shaped nut is rotatably mounted on the mounting base 210 via a matching bearing. The tensioning elongation motor 222 is fixedly mounted on the mounting base 210. The drive gear is provided on the output end of the tensioning elongation motor 222. The driven gear is sleeved on the T-shaped nut and can rotate coaxially and synchronously with the T-shaped nut. The tensioning elongation T-shaped screw 221 is threadedly connected to the T-shaped nut. The drive gear meshes with the driven gear. The tensioning elongation motor 222 drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby driving the T-shaped nut to rotate and drive the tensioning elongation T-shaped screw 221 to reciprocate along the axis of the T-shaped nut. The tensioning elongation motor 222 is electrically connected to the control system. The tensioning telescopic T-shaped lead screw 221 is connected to the rotary tensioning mechanism 250, thereby driving the rotary tensioning mechanism 250 to reciprocate.

[0038] In some preferred embodiments, the tensioning screw protection mechanism 230 includes a protective cover support frame 231 and a T-shaped screw cover 232. The T-shaped screw cover 232 is mounted on the protective cover support frame 231 and covers the portion of the tensioning elongated T-shaped screw 221 extending into the tensioning screw protection mechanism 230. The T-shaped screw cover 232 prevents the tensioning elongated T-shaped screw 221 from being contaminated by environmental factors such as dust and debris during use. This prevents the accumulation of dirt in the thread grooves of the tensioning elongated T-shaped screw 221, which could affect the pulling effect on the reinforcing cage 100 or cause jamming during the pulling process.

[0039] In some preferred embodiments, the guide rail base 240 includes a mounting base plate 241 and a slide rail 242, with the slide rail 242 mounted on the mounting base plate 241. The rotary tensioning mechanism 250 includes a sliding mounting plate 251, a slider 252, a mounting base 253, a bearing, a rotating shaft 254, a servo motor 255, a drive pulley, a synchronous pulley, a synchronous belt, a tensioning disc mounting bracket 256, and a tensioning head 257. The sliding mounting plate 251 is slidably mounted on the slide rail 242 via the slider 252. The mounting base 253 is mounted on the sliding mounting plate 251. The bearing is mounted on the mounting base 253. The servo motor 255 is mounted on the sliding mounting plate 251. The drive pulley is located at the output end of the servo motor 255. The rotating shaft 254 is rotatably mounted on the bearing. The synchronous pulley is mounted on the rotating shaft 254. The synchronous belt is sleeved on the drive pulley and the synchronous pulley. The tensioning disc mounting bracket 255... 6. The tensioning head 257 is mounted on the tensioning plate mounting bracket 256 and installed on the rotating shaft 254. In practice, one end of the reinforcing cage 100 is mounted on the tensioning head 257. The servo motor 255 drives the pulley to rotate, thereby driving the synchronous pulley to rotate. This causes the rotating shaft 254 and the tensioning plate mounting bracket 256 on it to rotate, which in turn drives the tensioning head 257 to rotate. At the same time, the tensioning elongation T-shaped screw 221 extending to one side of the rotating tensioning mechanism 250 is rotatably connected to the mounting base 253. The tensioning elongation motor 222 drives the rotating tensioning mechanism 250 to slide on the slide rail 242 to tighten the reinforcing cage 100, thereby achieving the operation of tightening (stretching) the reinforcing cage 100. The servo motor 255 is electrically connected to the control system.

[0040] In some preferred embodiments, a tensioning plate support frame 260 is further included, disposed on the sliding mounting plate 251, for supporting the tensioning head 257; wherein, the tensioning plate support frame 260 includes an arc-shaped support plate 261, an electric telescopic push rod 262, a mounting block 263, a guide seat 264, and a guide rod 265. The guide seat 264 is mounted on the sliding mounting plate 251, the guide rod 265 is slidably disposed on the guide seat 264 and vertically arranged, the top of the guide rod 265 is connected to the lower surface of the mounting block 263, the arc-shaped support plate 261 is mounted on the upper surface of the mounting block 263, and the arc-shaped support plate 261 is concave downwards. Rod 262 is mounted on the sliding mounting plate 251. The output end of the electric telescopic push rod 262 is connected to the mounting block 263. The electric telescopic push rod 262 is electrically connected to the control system. Through the telescopic drive of the electric telescopic push rod 262, the arc-shaped support plate 261 is raised upward until it abuts against the tensioning head 257. By supporting the tensioning head 257 with the arc-shaped support plate 261, the tilting or tilting of the main reinforcement straightening device 200 of the steel cage 100 due to excessive mass can be effectively avoided, thus preventing the coaxiality of the steel cage 100 during rotation and also preventing the quality of spiral reinforcement winding from being affected.

[0041] Preferably, the spiral reinforcement winding device 400 includes a mounting slide rail 410, a rack 420, a limiting block 430, a traveling mechanism 440, a spiral reinforcement feeding mechanism 450, and an anti-knotting feeding mechanism 460. The mounting slide rail 410 is laid in the working area, and the limiting block 430 is provided on both ends of the mounting slide rail 410. The rack 420 is disposed on the inner side of the mounting slide rail 410 and extends in the same direction as the mounting slide rail 410. The traveling mechanism 440 is mounted on the mounting slide rail 410 and can slide along the mounting slide rail 410. The spiral reinforcement feeding mechanism 450 and the anti-knotting feeding mechanism 460 are mounted on the traveling mechanism 440. The spiral reinforcement output from the spiral reinforcement feeding mechanism 450 passes through the anti-knotting feeding mechanism 460 and is evenly wound on the reinforcing cage 100.

[0042] In some preferred embodiments, the traveling mechanism 440 includes a small wheel 442 mounted on the traveling trolley frame 441, a traveling trolley servo motor 443, a trolley correction wheel 444, and a trolley anti-rollover limiting plate 445. The small wheel 442 is rolled on the mounting rail 410, and the trolley anti-rollover limiting plate 445 is slidably fastened to the edge of the mounting rail 410. The trolley correction wheel 444 makes rolling contact with the edge surface of the mounting rail 410. Through the setting of the trolley correction wheel 444 and the trolley anti-rollover limiting plate 445, it can be ensured that the traveling mechanism 440 can travel stably along the mounting rail 410 without deviation or tilting during travel. The output end of the traveling trolley servo motor 443 is provided with a traveling drive gear 446, which meshes with the rack 420. The servo motor 443 provides the power for the traveling mechanism 440 to move. The servo motor 443 drives the traveling gear 446 to rotate, thereby driving the traveling mechanism 440 to move on the mounting slide rail 410 under the action of the rack 420. The travel range of the traveling mechanism 440 is limited by the limiting block 430. It is worth mentioning that the limiting block 430 is equipped with a proximity switch. When the traveling mechanism 440 moves to the limiting block 430 and touches the limiting block 430, the traveling mechanism 440 stops moving, and the servo motor 443 is electrically connected to the control system.

[0043] In some preferred embodiments, the spiral rib feeding mechanism 450 includes a rotary shaft servo motor 451, a rotary shaft 452, a spiral rib feeding disc 453, a rotary drive gear, a rotary driven gear, and a synchronous gear chain.

The rotary driven gear is mounted on the rotary shaft 452, and the synchronous gear chain is sleeved on the rotary drive gear and the rotary driven gear. The spiral rib feeding disc 453 is used to carry spiral rib bundles. The rotary shaft servo motor 451 drives the rotary drive gear, which in turn drives the rotary shaft 452 to rotate, thereby rotating the spiral rib feeding disc 453 and releasing the spiral rib ribs. The rotary shaft servo motor 451 is electrically connected to the control system.

[0044] In some preferred embodiments, the anti-knotting wire feeding mechanism 460 includes a mounting rod 461, a support plate 462, a correction wheel 463, an anti-knotting force measuring part 464, and a straightening wheel set 465. The mounting rod 461 is mounted on the traveling trolley frame 441, the support plate 462 is mounted on the mounting rod 461, and the correction wheel 463, the anti-knotting force measuring part 464, and the straightening wheel set 465 are all mounted on the support plate 462. The reinforcing wires drawn from the spiral wire feeding disc 453 are sequentially threaded through... The spiral reinforcement wires are wound onto the reinforcing cage 100 via the straightening wheel 463, the anti-knotting force measuring part 464, and the straightening wheel set 465. Through the coordinated operation of the straightening wheel 463, the anti-knotting force measuring part 464, and the straightening wheel set 465, it is ensured that the output spiral reinforcement wires can be accurately wound onto the reinforcing cage 100. During the transportation process, the spiral reinforcement wires are straightened and corrected by the straightening wheel set 465. The anti-knotting force measuring part 464 controls the speed of the output spiral reinforcement wires to ensure that the spiral reinforcement wires can be tightly wound onto the reinforcing cage 100.

[0045] Next, the working principle and operation process of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0046] S1: One end of the steel cage 100 to be produced is fixedly connected to the tensioning head 257 on the main reinforcement straightening device 200. Similarly, the other end of the steel cage 100 is installed on the tensioning head on the active rotating force measuring device 300. The steel cage 100 with the tensioning heads installed at both ends is placed on the corresponding rotating tensioning mechanism 250 and the tensioning installation assembly of the active rotating force measuring device 300 by hoisting or transportation. (During the installation process, the tensioning head is first disassembled and connected to the end of the steel cage 100, and then placed together with the steel cage 100 body on the devices located at the corresponding ends of the steel cage 100.)

[0047] S2: Under the control of the control system, the main reinforcement straightening device 200 and the active rotation force measuring device 300 are started simultaneously. The active rotation force measuring device 300, as the active fixed end, drives the main reinforcement 100 to rotate. The main reinforcement straightening device 200, as the driven end, also rotates synchronously with the rotation of the active rotation force measuring device 300, so as to ensure that the main reinforcement 100 can maintain a stable rotation state.

[0048] S3: During the rotation process, the main reinforcement straightening device 200 of the steel cage simultaneously tensions the main reinforcement of the steel cage 100. Under the combined action of the main reinforcement straightening device 200 and the active rotation force measuring device 300, the steel cage 100 is tightened (stretched). At this time, the steel cage 100 is in a state of rotation and tension.

[0049] S4: While the main reinforcement straightening device 200 tensions the main reinforcement cage 100, the reaction force of the tensioning will be transmitted along the tensioned main reinforcement cage 100 to the active rotation force measuring device 300 and detected by the active rotation force measuring device 300. The active rotation force measuring device 300 will feed back the real-time detected tension force value to the control system in the form of an electrical signal, and the control system will process and analyze it. When the tension force on the main reinforcement cage 100 reaches the limit value (set value), the control system will control the main reinforcement straightening device 200 to stop tensioning the main reinforcement cage 100 (the tensioning state is locked, and the main reinforcement cage 100 only rotates at this time).

[0050] S5: When the reinforcing cage 100 is in a stable rotating state, that is, when the reinforcing cage 100 is no longer tensioned and the tension is constant, the control system first stops the rotation of the reinforcing cage 100, pulls out the spiral bar from the spiral bar winding device 400, connects the pulled-out end of the spiral bar to the designated position on the reinforcing cage 100, and starts the spiral bar winding device 400. Under the control of the control system, the traveling speed of the trolley mechanism 440 is matched with the main shaft rotation speed of the active rotation force measuring device 300. By controlling the traveling speed of the trolley mechanism 440, the pitch of the spiral bar wound on the reinforcing cage 100 is controlled. The feeding speed of the spiral bar feeding mechanism 450 is matched with the main shaft rotation speed of the active rotation force measuring device 300. By controlling the feeding speed of the spiral bar feeding mechanism 450 and the traveling speed of the trolley mechanism 440, the number of turns of the spiral bar wound on the reinforcing cage 100 can be precisely controlled.

[0051] S6: Cut the completed spiral reinforcement bars to complete the construction of the steel cage.

[0052] In summary, this utility model provides a spiral reinforcement winding device for utility pole reinforcement cages. One end of the reinforcement cage is installed on a main reinforcement straightening device that acts as a driven rotation and tensioner, while the other end is installed on an active rotation force measuring device that acts as the active rotationer. The active rotation force measuring device serves as the active fixed end, and the reinforcement cage is tightened (stretched) by the driven main reinforcement straightening device. Under the synchronous rotation of the main reinforcement straightening device and the active rotation force measuring device, the tightened reinforcement cage rotates at a uniform speed. In conjunction with this, the spiral reinforcement winding device moves slowly along the axis of the reinforcement cage and delivers the spiral reinforcement, so that the spiral reinforcement is evenly wound on the reinforcement cage. This enables rapid production of reinforcement cages, improves production efficiency, and ensures product quality.
