Description

Technical Field

[0001] This invention relates to the field of welding technology for the reinforcing steel skeleton of cement utility poles, and in particular to a welding device for producing the internal reinforcing steel skeleton of cement utility poles. Background Technology

[0002] Current cement utility poles are typically made of a steel reinforcement frame and poured concrete. This is achieved by welding multiple steel bars into a steel reinforcement frame, then pouring the steel reinforcement frame and concrete into a cavity used to form the utility pole. After the concrete hardens, it encases the steel reinforcement frame, thus increasing the structural strength of the utility pole.

[0003] Patent CN110936491B, entitled "A Manufacturing Process for Precast Cement Utility Poles," discloses a precast cement utility pole reinforcement cage fixing device. This device includes a base, which is horizontally fixed. The bottom of the base is supported by support legs. The top of the base has a first support frame and a second support frame with identical structures. The first support frame is vertically fixed to the top of the base, and the second support frame is vertically installed on the top of the base, with the first and second support frames facing each other at the top of the base. The bottom of the second support frame has a slider. The top of the base, near the right side wall, has a groove. The slider is inserted into the groove through a sliding fit. A threaded hole is provided in the middle of the slider. A motor is installed on the right side wall of the base, and a lead screw is connected to the output shaft of the motor. The other end of the lead screw passes through the threaded hole in the middle of the slider. However, the steel reinforcement cage fixing device in this patent requires manual loading of the steel reinforcements onto the first and second support frames in sequence during the processing of the cage. Then, the stirrups are arranged manually to the inside of the steel reinforcements, and then the stirrups are welded manually between adjacent steel reinforcements using a welding gun. Therefore, the process is very cumbersome and the welding efficiency is low. It is impossible to achieve automatic feeding and welding of steel reinforcements. Now, it is necessary to design a welding device for the production of internal steel reinforcement cages for cement utility poles. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding device for producing the internal steel reinforcement skeleton of cement utility poles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] As a further improvement of the present invention, the driving mechanism includes a rotating shaft disposed inside the mounting groove, both ends of which are rotatably connected to the inner wall of the mounting groove. A stepper motor is mounted on the outer wall of the mounting frame, and the output end of the stepper motor passes through the mounting frame and is fixedly connected to the end of the rotating shaft. A first gear is fixedly sleeved on the rotating shaft. A gear ring is fixedly sleeved on the side wall of the mounting plate, and the gear ring meshes with the first gear.

A fourth hydraulic cylinder is mounted on the inner wall of the mounting groove. A moving rod is fixedly connected to the telescopic end of the fourth hydraulic cylinder.

A moving plate is fixedly sleeved on the moving rod, and a pressure switch is mounted on the lower end of the moving plate.

[0012] As a further improvement of the present invention, a feeding groove communicating with the feeding groove is provided on the side wall of the base, and a feeding guide plate corresponding to the position of the feeding groove is fixedly connected to the side wall of the base.

[0013] As a further improvement of the present invention, the locking rod is a rectangular rod.

[0014] As a further improvement of the present invention, a connecting post is fixedly connected between the two mounting disks.

[0015] The beneficial effects of this invention are:

[0016] 1. By setting up a feeding mechanism and starting the extension of the first hydraulic cylinder, the feeding pallet can be driven to move upward. The feeding pallet lifts the steel bars upward and moves both ends of the steel bars into the clamping slots on the two mounting plates respectively. When the feeding pallet descends, the steel bars automatically enter the feeding trough through the feeding trough under the action of gravity and fall onto the feeding pallet, which can realize the automatic feeding of steel bars by the feeding pallet.

[0017] 2. By setting up a feeding guide plate, the steel bars can be arranged in the feeding guide plate and automatically enter the feeding trough under the action of gravity, thus realizing automatic feeding of steel bars.

[0018] 3. By setting up a clamping mechanism, after both ends of the steel bar enter the clamping groove, the slide plate continues to move upward, which can push the extrusion block upward through the top rod. The extrusion block squeezes the two clamping blocks, which can make the two clamping blocks approach synchronously and clamp and fix the two ends of the steel bar. Thus, the steel bar can be automatically fed and automatically clamped on the installation plate.

[0019] 4. By setting a locking mechanism, when the locking rod is engaged in the locking hole on the extrusion block, the extrusion block can be locked, thereby maintaining the clamping state of the clamping block on the reinforcing bar and ensuring the stability of the reinforcing bar clamping.

[0020] 5. By setting up a pressure switch, a protrusion, and a welding mechanism, the guide rod can lay out and position the steel wire to contact the outside of the rebar. When the protrusion rotates to contact the pressure switch, it can trigger the pressure switch and start the extension of the electric telescopic rod. The electric telescopic rod can then drive the welding torch to the contact point between the rebar and the steel wire to complete the welding. Furthermore, the rotation of the threaded rod can drive the translation plate to move, thereby automatically laying out the steel wire along the radial direction of the rebar, which greatly improves the efficiency of laying the steel wire on the outside of the rebar.

[0021] 6. By setting up a drive mechanism, a stepper motor drives the rotating shaft to rotate, which in turn drives the first gear to rotate. The first gear drives the gear ring to rotate, which in turn drives the mounting plate to rotate. This allows multiple steel bars to be clamped sequentially inside the clamping slot, making the loading and clamping of steel bars more efficient. After the steel bars are clamped, the fourth hydraulic cylinder is activated to extend, driving the moving rod to move. The movement of the moving rod drives the second gear to mesh with the first gear through the shift fork. The moving rod then drives the moving plate to move above the protrusion, so that the rotation of the steel bars and the laying of the steel wire are linked. This allows the steel wire to be quickly wrapped and laid on the outside of the steel bars. By adjusting the position of the second gear and the pressure switch, the loading and clamping of steel bars and the laying and welding of steel wire can be prevented from interfering with each other.

[0022] This invention enables automatic feeding of reinforcing bars onto a feeding pallet and automatic clamping of the reinforcing bars onto an installation plate. By linking the rotation of the reinforcing bars with the laying and welding of the steel wire, the steel wire can be quickly wound and welded to the outside of the reinforcing bars, thereby greatly improving the efficiency of welding the steel wire to the outside of the reinforcing bars.

One end of the second spring 33 is connected to the inner top wall of the mounting hole 32, and the other end of the second spring 33 is connected to the pressing block 30.

[0036] The specific locking mechanism includes a pull plate 27. A third hydraulic cylinder 17 is installed on the side wall of the mounting bracket 15. The telescopic end of the third hydraulic cylinder 17 is rotatably connected to the center of the side wall of the pull plate 27. The side wall of the pull plate 27 is provided with six locking elements evenly distributed along its circumference. The locking elements include a locking rod 28 that passes through the pull plate 27. The locking rod 28 is slidably connected to the pull plate 27. One end of the locking rod 28 passes through the side wall of the mounting plate 16 and extends into the interior of the movable groove 31. The side wall of the pressing block 30 is provided with a locking hole that cooperates with the locking rod 28. The locking rod 28 is a rectangular rod. A tension spring 29 is fitted on the side wall of the locking rod 28. One end of the tension spring 29 is connected to the pull plate 27, and the other end of the tension spring 29 is connected to the mounting plate 16.

[0037] The specific drive mechanism includes a rotating shaft 42 disposed inside the mounting groove 41, with both ends of the rotating shaft 42 rotatably connected to the inner wall of the mounting groove 41. A stepper motor 26 is mounted on the outer wall of the mounting bracket 15, and the output end of the stepper motor 26 passes through the mounting bracket 15 and is fixedly connected to the end of the rotating shaft 42. A first gear 40 is fixedly sleeved on the rotating shaft 42. A gear ring 39 is fixedly sleeved on the side wall of the mounting plate 16, and the gear ring 39 meshes with the first gear 40. A second gear 43 is slidably sleeved on the side wall of the threaded rod 19 located inside the mounting groove 41. The second gear 43 meshes with the first gear 40. A fourth hydraulic cylinder 45 is installed on the inner wall of the mounting groove 41. A moving rod 46 is fixedly connected to the telescopic end of the fourth hydraulic cylinder 45. A shift fork 44 is fixedly sleeved on the moving rod 46. The shift fork 44 is engaged with the outside of the second gear 43. A moving plate 47 is fixedly sleeved on the moving rod 46. A pressure switch 48 is installed at the lower end of the moving plate 47. Six protrusions 38 are fixedly connected to the peripheral wall of the mounting plate 16, which are evenly distributed along the circumference. The positions of the six protrusions 38 correspond one-to-one with the six clamping grooves 35.

[0038] When this invention is used, the reinforcing bars are arranged in the feeding guide plate 36, and the reinforcing bars can automatically be arranged into the feeding trough 11 under the action of gravity. The reinforcing bars enter the loading trough 2 through the feeding trough 11. The first hydraulic cylinder 4 is activated to extend, driving the slide plate 9 to move upward. The slide plate 9 drives the loading pallet 10 to move upward. The loading pallet 10 lifts the reinforcing bars upward, and the two ends of the reinforcing bars move into the clamping slots 35 on the two mounting plates 16 respectively. After the two ends of the reinforcing bars enter the clamping slots 35, the slide plate 9 continues to move upward, and the pressing block 30 is lifted upward by the top rod 8. The pressing block 30 presses the two clamping blocks 34, so that the two clamping blocks 34 move closer to each other and clamp and fix the two ends of the reinforcing bars. Thus, the reinforcing bars are automatically fed and automatically clamped on the mounting plate 16.

[0039] Then, the first hydraulic cylinder 4 is activated to retract, causing the slide plate 9 to move downward. When the feeding tray 10 descends, the steel bars automatically enter the feeding tray 2 through the feeding groove 11 under the action of gravity and fall onto the feeding tray 10, which can realize the automatic feeding of steel bars by the feeding tray 10. The first stepper motor 26 drives the rotating shaft 42 to rotate, which drives the first gear 40 to rotate. Since the first gear 40 meshes with the gear ring 39, it can drive the gear ring 39 to rotate, and drive the mounting plate 16 to rotate through the gear ring 39, thereby causing the next clamping slot 35 to rotate to the top of the feeding tray 2. Repeat the above process to automatically clamp the steel bars onto the mounting plate 16 in sequence.

[0040] After the rebar is clamped, the fourth hydraulic cylinder 45 is extended, which drives the moving rod 46 to move. The moving rod 46 can drive the second gear 43 to mesh with the first gear 40 through the shift fork 44. The moving rod 46 drives the moving plate 47 to move above the protrusion 38. At this time, when the stepper motor 26 drives the rotating shaft 42 to rotate, the rotating shaft 42 can drive the threaded rod 19 to rotate in conjunction. The guide rod 23 can lay and position the steel wire to contact the outside of the rebar. When the protrusion 38 rotates to contact the pressure switch 48, it can trigger the pressure switch 48 and start the extension of the electric telescopic rod 25. Then, the electric telescopic rod 25 can drive the welding torch 24 to move to the contact part between the rebar and the steel wire to complete the welding. The rotation of the threaded rod 19 can drive the translation plate 20 to translate, thereby automatically laying the steel wire along the radial direction of the rebar. This can realize the rapid winding of the steel wire to the outside of the rebar, which greatly improves the efficiency of laying and welding the steel wire to the outside of the rebar.

[0041] After welding is completed, the third hydraulic cylinder 17 is activated to retract, which moves the pull plate 27. The pull plate 27 pulls the locking rod 28 out of the locking hole on the extrusion block 30, thus releasing the clamping of the reinforcing bar. Then, the second hydraulic cylinder 13 is activated to retract, which moves the two support seats 14 away, releasing the support of the skeleton. The welded skeleton is then removed.

[0042] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
