Description

Technical Field

[0001] This invention relates to the field of tower crane processing equipment, and more specifically to an automatic welding mechanism for a tower base climbing frame. Background Technology

[0002] Currently, if workers are climbing inside a tower crane, a climbing frame needs to be installed within the standard section to facilitate their ascent. The current climbing machine primarily involves workers cutting the pole into multiple sections and then placing these sections onto a welding mold for welding. This process is relatively inefficient (requiring manual cutting and placement of the cut sections on the welding mold), requiring a large workforce and resulting in low efficiency, which contradicts the current trend of transitioning from traditional manual manufacturing to intelligent manufacturing. Summary of the Invention

[0020] The invention will now be further described with reference to the accompanying drawings.

[0021] like Figure 1-7As shown, an automatic welding mechanism 3 for a tower base climbing frame includes a cutting mechanism 1, a swaying mechanism 2, and a welding mechanism 3. The cutting mechanism 1 and the welding mechanism 3 are arranged side by side from bottom to top. The swaying mechanism 2 is set between the cutting mechanism 1 and the welding mechanism 3, that is, the welding mechanism 3 is located above the cutting mechanism 1. The cut rods are swayed on the welding mechanism 3 through the swaying mechanism 2 for welding. The cutting mechanism 1 includes a support frame cutting assembly 1.1, a pedal frame cutting assembly 1.7, and a transfer assembly 1.12. There are two sets of support frame cutting assemblies 1.1, and the two sets of support frame cutting assemblies 1.1 are parallel to each other (that is, the two sets of support frame cutting assemblies 1.1 are longitudinally parallel). The support frame cutting assembly 1.1 includes a rotating cylinder 1. 2. The clamping slot 1.4 and the first saw blade 1.5, and the rotating cylinder 1.2 are driven by a motor (both ends of the rotating cylinder 1.2 are mounted on the column via bearings, and the left end of the rotating cylinder 1.2 is welded to the output shaft of the stepper motor to achieve rotation). Multiple clamping slots 1.4 arranged in a circular array are opened on the outer circumference of the rotating cylinder 1.2. The rod extends into the clamping slot 1.4 for clamping. A baffle 1.6 is welded to the left end of the rotating cylinder 1.2, and the left end of the rod abuts against the baffle 1.6 for limiting its position. A conveying track 4 (which consists of multiple rollers arranged side-by-side and driven by a motor) is connected to the right side of the rotating cylinder 1.2 away from the baffle 1.6. The rotating cylinder 1.2 rotates, and the rod is placed on the roller for conveying. The roller conveys the rod into the clamping slot 1.4. The long rod is conveyed into the clamping slot 1.4 via the conveying track 4. A first saw blade 1.5, which can swing, is installed between the rotating cylinder 1.2 and the conveying track 4. The saw blade cuts the rod. (The first saw blade 1.5 is driven to rotate by a motor. A hydraulic cylinder for lifting is fixed between the motor of the first saw blade 1.5 and the ground by bolts. The extension and retraction of the hydraulic cylinder realizes the raising and lowering of the first saw blade 1.5. When the first saw blade 1.5 rises, it cuts the rod. The rotating cylinder 1.2 then rotates, and the rod extends into the next clamping slot 1.4.) The rod is clamped and cut above the first saw blade 1.5 when it rests against the baffle 1.6. A transfer assembly 1.12 (transfer assembly 1.12 is arranged horizontally) is set between the two sets of support frame cutting assemblies 1.1. A pedal frame cutting assembly 1.7 is set on the right end of the transfer assembly 1.12. The pedal cutting assembly cuts the rod into multiple pedal segments. The transfer assembly 1.12 installs the cut pedal segments between the two support frame cutting assemblies 1.1. The pedal cutting assembly includes a second saw blade 1.8, a limiting plate 1.9, and a pressing assembly 1.10. A swingable second saw blade 1.8 (two blades 1.8) is set on the right side of the transfer assembly 1.12.8. The shaft is fixed and rotates synchronously. Both ends of the shaft are mounted on the swing arm via bearings, and the other end of the swing arm is hinged to the ground. A hydraulic cylinder is installed between the ground and the swing arm via the hinge. The swing arm is swung by the hydraulic cylinder, thus allowing the second saw blade 1.8 to move closer to or closer to the main shaft. A conveyor track 4 for conveying the main shaft onto the second saw blade 1.8 is fixed to the ground in front of the second saw blade 1.8 by bolts. A limit plate 1.9 is fixed to the side of the second saw blade 1.8 away from the conveyor track 4 (on the rear side of the ground) by bolts. The rear end of the pedal abuts against the limit plate 1.9. Two sets of pressing components 1.10 are provided between the limit plate 1.9 and the second saw blade 1.8. Component 1.10 presses the rod (the pressing component 1.10 consists of upper and lower pulleys, with a hydraulic cylinder mounted on the sliding surface via bolts. The lifting and retraction of the hydraulic cylinder presses and releases the pedal. An annular groove is cut into the pulley, and the pedal is engaged within the groove for transport, preventing pedal misalignment during cutting). The transfer component 1.12 attracts the rod cut by the second saw blade 1.8, moving the rod between the second saw blades 1.8. The transfer component 1.12 then attracts and transports the pedal to the left. After the pedal is cut, it moves away via the transfer component 1.12, placing the pedal between the two support frames, thus enabling the pedal and support rod to swing and connect. A swing mechanism 2 is provided between the support frame cutting assembly 1.12 and the support frame cutting assembly 1.1. The swing mechanism 2 includes a movable pallet 2.1, limiting grooves 2.3, and a support frame clamping assembly 2.4. The bottom of the movable pallet 2.1 is provided with a translation assembly 2.2 (the translation assembly 2.2 is a horizontal linear motor 2.13, and the moving part sliding seat 3.6 of the linear motor 2.13 is bolted to the bottom of the movable pallet 2.1, enabling the left and right movement of the movable pallet 2.1). The movable pallet 2.1 is driven by the translation assembly 2.2. Multiple sets of limiting grooves 2.3 are provided on the movable pallet 2.1, and the limiting grooves 2.3 protrude from the top of the movable pallet 2.1 (there are multiple limiting grooves 2.3). .3 The horizontally arranged side by side limit grooves 2.3 correspond vertically to the pedals on the transfer assembly 1.12 (the pedals on the transfer assembly 1.12 are clamped in the limit grooves 2.3 for limiting). Support frame clamping assemblies 2.4 are provided on the front and rear sides of the movable push plate. The support frame clamping assemblies 2.4 are installed on the factory roof and clamp the support frames. A clamping assembly 2.8 is provided on the support frame clamping assembly 2.4 to clamp the two support frames together, thus clamping the pedals on the inside of the support frames. A pre-welded assembly 2.12 is provided on the support frame clamping assembly 2.4 and slides on it.4. The moving plate 2.1 moves to weld the top of the pedal and the support rod, thus achieving a preliminary welding and pre-connection between the support rod and the pedal. The pre-welding assembly 2.12 completes the initial welding of the support frame and the pedal. A flipping assembly 5 is located above the end of the moving plate 2.1. A clamping assembly 6 is located on the flipping assembly to clamp the climbing frame. When the moving plate 2.1 moves below the flipping assembly 5, the clamping assembly 6 on the flipping assembly 5 clamps and flips the pre-welded climbing frame, causing the climbing frame to rotate above the flipping assembly 5. Welding mechanisms 3 are located above both sides of the flipping assembly 5 to weld the climbing frame. The welding mechanism 3 includes... The assembly comprises a swing arm 3.1, a bottom welding assembly 3.3, and a side welding assembly 3.11. There are two swing arms 3.1 (two swing arms 3.1 are arranged horizontally, with both ends mounted on a cantilever via bearings, and the top of the cantilever mounted on the roof via bolts). The two swing arms 3.1 are distributed on the front and rear sides of the flip assembly 5. The swing arms 3.1 are rotated by a motor (one end of each swing arm 3.1 is welded to the motor's output shaft, and the motor drives the rotation of the swing arm 3.1). Multiple horizontally arranged mounting seats 3.2 are fixed to each swing arm 2.6 by bolts. Each mounting seat 3.2 has a [missing information - likely a design element or component]. A sliding assembly 3.4 is provided between the bottom welding assembly 3.3 and the side welding assembly 3.11, and between the ground welding assembly and the mounting base 3.2. The sliding assembly 3.4 enables the bottom welding assembly 3.3 to weld the bottom surface of the climbing frame. A lifting assembly 3.12 is provided between the side welding assembly 3.11 and the bottom of the mounting base 3.2. The lifting assembly 3.12 enables the side welding assembly 3.11 to be raised and lowered, thus welding the side of the pedal to the support frame. The lifting assembly 3.12 and the sliding assembly 3.4 are linked to achieve synchronous welding. During operation, the rod is conveyed into the clamping slot 1.4 of the rotating cylinder 1.2, and then... A saw blade 1.5 cuts the rod body, the rotating cylinder 1.2 rotates, and the rod body extends into another clamping slot 1.4. At the same time, the first saw blade 1.5 lifts and cuts the rod body. Simultaneously, the rod body of the pedal is conveyed and abuts against the limiting plate 1.9. The second saw blade 1.8 cuts the rod body to form the pedal. The pedal is conveyed to the top of the moving pallet 2.1 via the transfer assembly 1.12. In this way, the support frame and the pedal are assembled on the moving pallet 2.1. The assembled support frame and the top surface of the pedal are welded by the pre-welding assembly 2.12 to achieve the initial fixation of the two sets. The moving pallet 2.1 moves to the left and below the flipping assembly 5. The clamping assembly 6 on the flipping assembly 5 clamps the moving pallet 2.The climbing frame is clamped in position below the flipping assembly 5. The flipping assembly 5 rotates 180 degrees, flipping the climbing frame above the welding mechanism 3. With the unwelded bottom surface of the climbing frame facing upwards, welding is facilitated by the welding mechanism 3. During welding, while the bottom welding assembly 3.3 moves laterally, the side welding assembly 3.11 moves vertically downwards, allowing bottom and side welding to proceed simultaneously. The welding mechanism 3 then swings outwards via the swing rod 3.1, causing the flipping assembly 5 to rotate 180 degrees. Simultaneously, the clamping assembly 6 releases the climbing frame. Since the climbing frame is now below the flipping assembly 5, it falls off, completing the unloading process.

[0022] The bottom welding assembly 3.3 is the first welding head. The sliding assembly 3.4 includes a sliding groove 3.5, a sliding seat 3.6, and a rack 3.7.

A motor is fixed on the top of the mounting base 3.2 by bolts, and the output shaft of the motor passes through the mounting base 3.2 and is welded to the gear 3.8. The motor realizes the rotation of the gear 3.8, and the gear 3.8 meshes with the rack 3.7. The rotation of the gear 3.8 realizes the left and right translation of the rack 3.7. A vertically downward-pointing lead screw 3.9 is fixed to the bottom of component 8 by welding. A sliding sleeve 3.10, which is threadedly engaged with the lead screw 3.9, is fitted onto the lead screw 3.9. The side welding assembly 3.11 is the second welding head.
