Description

Technical Field

[0001] This invention relates to the field of angle iron drilling technology, specifically to an angle iron drilling device for processing power transmission tower components. Background Technology

[0002] Transmission towers are the core supporting components of high-voltage, ultra-high-voltage, and extra-high-voltage power transmission networks, directly determining the operational stability, load-bearing safety, and service life of transmission lines. Transmission towers adopt a spatial truss structure, primarily assembled from equilateral angle steel and composite angle steel of different specifications using bolts and fasteners. The quality of bolt hole processing for angle steel components is a crucial process for ensuring the tower's assembly accuracy, structural strength, and overall load-bearing capacity. With the increasing scale and standardization of domestic power grid construction, and the continuously rising requirements for the precision and consistency of tower components in high-voltage transmission projects, the processing precision, structural stability, automation level, and adaptability of angle steel hole-making equipment have become core factors restricting the production quality and processing efficiency of tower components.

[0003] Currently, the mainstream hole-making processes for angle steel in power transmission towers are punching and drilling. Punching is faster and less expensive, but when processing Q345 high-strength, thick-walled angle steel and large-diameter installation holes, it easily causes defects such as edge extrusion deformation, micro-cracks inside the steel, and severe burrs on the hole wall, significantly reducing the load-bearing capacity of the angle steel structure and failing to meet the high safety standards of high-voltage power transmission towers. Therefore, for high-strength, thick-walled, and high-precision tower load-bearing angle steel components, the industry generally uses drilling instead of punching to ensure hole wall smoothness, hole diameter accuracy, and overall structural strength. However, currently used drilling equipment easily generates flying debris during drilling, affecting the construction environment and posing safety hazards. Furthermore, the drilling angle and position are inconvenient to adjust, and the switching speed between fixed and moving workpiece states is slow. Summary of the Invention

[0016] The suspension gripper is attached to the top of the rotating disk. A telescopic push rod is fixedly connected to the top of the suspension gripper. The rotating disk can be removed from the suspension gripper by the suspension gripper, which facilitates the maintenance of the mechanism on the rotating disk.

[0017] Preferably, the top of the telescopic push rod is fixedly connected to the inner wall of the drilling bracket, and two sets of fixing devices are provided and symmetrically distributed on both sides of the rotating disk.

[0018] Preferably, the fixing device includes:

[0019] The arc-shaped base is concentric with the rotating disk in the shape of an arc. Arc-shaped slides are provided on both sides of the arc-shaped base, and telescopic holes are provided on the convex side of the arc-shaped base.

[0020] A movable slide plate is provided with an arc shape that is adapted to the arc-shaped slide track. The movable slide plate is disposed inside the arc-shaped slide track. Friction pads are fixedly connected to both sides of the movable slide plate, which can increase the friction between the movable slide plate and the inner wall of the arc-shaped slide track.

[0021] A movable plate is set on one side of an arc-shaped base. An elastic telescopic rod is fixedly connected to one side of the movable plate. The end of the elastic telescopic rod away from the movable plate is fixedly connected to a movable sliding piece.

[0022] An extrusion block is provided with chamfered edges on both sides. The extrusion block is disposed inside the telescopic hole and is slidably connected to the inner wall of the telescopic hole. An extrusion push rod is fixedly connected to one side of the extrusion block. The end of the extrusion push rod away from the extrusion block extends to the outside of the telescopic hole and is fixedly connected to the arc-shaped base.

[0023] Preferably, the side of the arc-shaped base away from the telescopic hole is fixedly connected to the side of the rotating disk via a connecting bracket, and the side of the movable plate away from the elastic telescopic rod is fixedly connected to the side of the electronic slide via a connecting bracket.

[0024] Preferably, the positioning device includes a support frame, a feeding track fixedly connected to the top of the support frame, a positioning base fixedly connected to the inner wall of the feeding track, a positioning groove opened on the top of the positioning base, a sliding ball rotatably connected to the inner wall of the positioning groove, a support sleeve slidably connected to the side of the sliding ball, a support spring fixedly connected to the inner wall of the support sleeve, one end of the support spring extending to the outside of the support sleeve and fixedly connected to the bottom of the inner wall of the positioning groove, one end of the support sleeve extending to the outside of the positioning groove and fixedly connected to a support roller via a bracket, positioning brackets fixedly connected to both ends of the top of the feeding track, a hydraulic push rod fixedly connected to the positioning bracket, a pressing head fixedly connected to the bottom of the hydraulic push rod, and a support block fixedly connected to the portion of the top of the feeding track below the hydraulic push rod.

[0025] Preferably, the support frame is mounted on the workbench and fixedly connected to the workbench, both sides of the support roller are set as arcs, multiple sets of positioning bases are provided, and multiple sets of sliding balls are provided and evenly distributed on the inner wall of the positioning groove.

[0026] It has the following beneficial effects:

[0027] 1. The angle iron drilling equipment for processing power transmission tower components features an arc-shaped protective cover fitted over the drilling device. This effectively blocks flying debris during drilling, preventing it from splashing onto other parts of the equipment and affecting the processing environment. It also prevents debris from injuring workshop workers. In addition, it is equipped with an adapter slot and a shielding strip. The shielding strip inside the adapter slot partially shields the area between the workpiece and the inner wall of the adapter slot, providing better protection. During use, the workpiece is inserted into the arc-shaped cover through the adapter slot. Areas without workpieces can hang down naturally for shielding. When a workpiece is pushed or lifted, the adjacent counterweights can be easily bent, preventing the shielding strip from being separated by the workpiece and creating large gaps, thus improving the shielding effect.

[0028] 2. The angle iron drilling equipment for processing power transmission tower components uses an electronic slider inside the electronic slide rail to move the fixed base and electric drill bit toward the workpiece, allowing drilling operations to be performed on the workpiece. Because the electronic slide rails on both sides of the rotating disk are crisscrossed, drilling can be performed on both sides of the workpiece simultaneously. Furthermore, the angles of the two sets of electric drill bits can be adjusted independently, enabling the equipment to maintain high processing efficiency while adapting to workpieces of different shapes and specifications. It offers good drilling flexibility and is also equipped with suspension grippers, allowing the rotating disk to be directly removed from the suspension grippers. In case of equipment failure, the rotating disk and its mechanism can be removed together for inspection and maintenance, facilitating maintenance.

[0029] 3. The angle iron drilling equipment for processing power transmission tower components can support the electric drill bit through the friction between the moving slide and the inner wall of the arc-shaped slide, making the electric drill bit more stable and also sharing the pressure borne by the rotating motor. Furthermore, the moving slide is fixed by the extrusion block, which can fix the moving slide in any position, allowing the electric drill bit to obtain greater adjustment freedom and making it more convenient to use.

[0030] 4. The angle iron drilling equipment for processing transmission tower components can fix the workpiece by the cooperation of the extrusion head and the support block. When it is necessary to move the workpiece, the hydraulic push rod drives the extrusion head to move upward, so that the workpiece moves upward and gets off the support block under the elastic force of the support spring. When the workpiece is completely reset, it can be moved by the feeding trolley. The workpiece is clamped by the cooperation of the extrusion head and the support block. The fixing operation is simple and efficient. In addition, since the support sleeve can move up and down inside the positioning groove, the extrusion force on the support roller is small during the clamping process. Therefore, the rolling parts of the support roller are less damaged during the drilling process, which also helps to reduce the use and maintenance costs. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] For the first embodiment, please refer to... Figures 1-3This invention provides a technical solution: a drilling device for angle iron in the processing of power transmission tower components. By setting a protective cover 4, during the drilling process of the drilling device 3, the arc-shaped cover 41 inside the protective cover 4 is fitted over the outside of the drilling device 3, which can block the flying debris during drilling, preventing debris from flying from the equipment to other places and affecting the processing environment. It also prevents debris from injuring workshop workers. In addition, an adapter slot 42 and a shielding strip 43 are provided. The workpiece to be processed can pass through the adapter slot 42 and be placed inside the arc-shaped cover 41, so that the arc-shaped cover 41 can completely cover the processing part. Furthermore, the shielding strip 43 inside the adapter groove 42 can also shield the part between the workpiece and the inner wall of the adapter groove 42, resulting in better protection. Multiple sets of counterweights 44 are set on the shielding strip 43, and the adjacent counterweights 44 are spaced apart, so that the shielding strip 43 can be bent and folded better. During use, the workpiece is inserted into the arc-shaped cover 41 through the adapter groove 42. Where there is no workpiece, it can hang down naturally for shielding. When the workpiece pushes or lifts the workpiece, the position between the adjacent counterweights 44 can be bent relatively easily, which can prevent the shielding strip from being separated by the workpiece and causing a large gap, thus making the shielding effect better.

[0042] For the second embodiment, please refer to... Figures 1-6 This invention provides a technical solution: During drilling, a rotating motor 32 drives an electronic slide rail 33 to rotate, which in turn drives a fixed base 34 to rotate. The fixed base 34 then drives an electric drill bit 35 to rotate. The rotation of the motor 32 causes the electric drill bit 35 to adjust its drilling angle to fit the shape of the workpiece. After adjusting the drilling angle, a telescopic push rod 37 drives a suspension gripper 36 to descend. The suspension gripper 36 then drives a rotating disk 31 to descend. The rotating disk 31, through the rotating motor 32 and the electronic slide rail 33, drives the fixed base 34 and the electric drill bit 35 to descend. When the electric drill bit 35 descends to the drilling position, the electric drill bit 35 passes through the interior of the electronic slide rail 33... The electronic slider moves the fixed base 34 and the electric drill bit 35 toward the workpiece, allowing drilling to be performed on the workpiece. Since the electronic slides 33 on both sides of the rotating disk 31 are crisscrossed, drilling can be performed on both sides of the workpiece simultaneously. The two sets of electric drill bits 35 can be independently and freely adjusted in angle, enabling the equipment to maintain high processing efficiency while adapting to workpieces of different shapes and specifications. The drilling flexibility is good. A suspension gripper 36 is also provided, and the rotating disk 31 can be directly removed from the suspension gripper 36. In case of equipment failure, the rotating disk 31 and its mechanism can be removed together for inspection and maintenance.

[0043] The drilling device 3 is also equipped with a fixing device 38. When the rotating motor 32 drives the electronic slide 33 to rotate, the electronic slide 33 drives the moving plate 384 to move, the moving plate 384 drives the elastic telescopic rod 385 to move, and the elastic telescopic rod 385 drives the moving slide 383 to move. When the electronic slide 33 rotates to a suitable angle, the extrusion push rod 388 drives the extrusion block 387 to move. During the movement of the extrusion block 387, it pushes the moving slide 383 to move to one side. During the movement of the moving slide 383, it compresses the elastic telescopic rod 385. The extrusion block 387 can then press the moving slide 383 against the inner wall of the arc-shaped slide 382. Thus, the moving slide 383 and the inner wall of the arc-shaped slide 382 can be pressed together. The friction between the movable slide plate 383 and the electric drill bit 35 fixes the movable slide plate 383 in place. Since the movable slide plate 383 is connected to the electronic slide rail 33 through the elastic telescopic rod 385 and the movable plate 384, the electronic slide rail 33, the fixed seat 34 and the electric drill bit 35 on it can be fixed. Thus, the electric drill bit 35 can be supported by the friction between the movable slide plate 383 and the inner wall of the arc-shaped slide rail 382, ​​making the electric drill bit 35 more stable and also sharing the pressure borne by the rotating motor 32. Furthermore, the movable slide plate 383 is fixed by the pressing block 387, which can fix the movable slide plate 383 in any position, allowing the electric drill bit 35 to obtain greater adjustment freedom and making it more convenient to use.

[0044] Third embodiment, please refer to Figures 1-8 This invention provides a technical solution: When fixing a workpiece, an external feeding trolley moves the workpiece to the feeding track 62 inside the positioning device 6. The workpiece is supported by support rollers 612 on the feeding track 62. The workpiece moves on the feeding track 62 via the support rollers 612. When the workpiece moves to the processing station, the hydraulic push rod 69 drives the extrusion head 610 to move downward. The extrusion head 610 extrudes the workpiece surface, pressing the workpiece down. After the workpiece is subjected to downward pressure, the downward pressure is transmitted to the support rollers 612. The downward movement of the support rollers 612 drives the support sleeve 66 to move downward. The support sleeve 66 slides inside the positioning groove 64, providing space for the workpiece to move downward. When the workpiece moves down to the position of the support rollers 612, the workpiece moves downward. When the workpiece is in contact with the support block 611, the workpiece can be fixed by the cooperation between the extrusion head 610 and the support block 611. When the workpiece needs to be moved, the hydraulic push rod 69 drives the extrusion head 610 to move upward, so that the workpiece moves upward and gets off the support block 611 under the elastic force of the support spring 67. When the workpiece is fully reset, the workpiece can be moved by the feeding carriage. The workpiece is clamped by the cooperation between the extrusion head 610 and the support block 611. The fixing operation is simple and efficient. In addition, since the support sleeve 66 can move up and down inside the positioning groove 64, the extrusion force on the support roller 612 is small during the clamping process. Therefore, the rolling parts of the support roller 612 are less damaged during the drilling process, which also helps to reduce the cost of use and maintenance.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
