Description

Technical Field

[0001] This utility model relates to the field of drilling and processing technology for iron tower angle steel, and specifically to a positioning and conveying fixture for iron tower angle steel. Background Technology

[0002] In the manufacturing process of steel structures such as power transmission towers and communication towers, angle steel is one of the most important load-bearing components. These angle steels need to undergo multiple processing steps such as cutting and punching.

[0003] However, due to the L / V-shaped cross-section of angle steel, regardless of which side of the angle steel is placed downwards on the conveyor table or raceway, its center of gravity is unlikely to fall within the supporting surface, resulting in an unstable equilibrium. This instability makes the angle steel prone to rolling, tipping over, or tilting during conveying. This not only affects the smoothness of the conveying process, requiring frequent manual intervention to straighten it, but also poses significant safety hazards, easily causing injury to equipment or operators. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning and conveying fixture for iron tower angle steel, so as to solve the problem that iron tower angle steel is prone to rolling, tipping over or tilting during the conveying process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The positioning and conveying fixture for the angle steel of the iron tower includes: Base; A support base is disposed on the base and includes a first support body and a second support body arranged at an angle, wherein an opening is formed between the first support body and the second support body, and the opening is V-shaped away from the base. The first conveying mechanism includes a plurality of rollers near the top of the opening, which are rotatably mounted on the first support and the second support, and support the angle steel of the tower. The second conveying mechanism includes a slider, an upper clamping arm, and a lower clamping arm. The slider is slidably disposed at the bottom of the opening. The upper clamping arm and the lower clamping arm are both disposed on the slider, and one of them can move relative to the other to form a clamping point for clamping the inner and outer end faces of the tower angle steel.

[0006] Furthermore, the number of rollers provided on the first support body and the second support body is the same, and they are arranged in a one-to-one correspondence.

[0007] Furthermore, the number of rollers provided on the first support and the second support are different, and they are arranged in an alternating manner.

[0008] Furthermore, a groove is provided at the bottom of the opening, and the slider is slidably disposed in the groove.

[0009] Furthermore, the upper clamping arm is movably disposed on the slider, and the lower clamping arm is fixed to the slider.

[0010] Furthermore, the upper clamping arm includes a movable part and a clamping part connected to each other. The movable part is rotatably disposed on the slider to move the clamping part closer to or away from the lower clamping arm.

[0011] Furthermore, the slider is movably provided with a pull rod, which is connected to the movable part and is used to pull or push the movable part to rotate in both directions.

[0012] Furthermore, the pull rod is equipped with a self-locking structure to allow it to be suspended at any position.

[0013] Furthermore, the clamping part is provided with a V-shaped protrusion.

[0014] Furthermore, the lower clamping arm is provided with a V-shaped groove.

[0015] Compared with the prior art, this utility model has the following beneficial effects: the angle steel of the tower is initially positioned by the opening formed between the first support body and the second support body to adapt to its cross-sectional shape; at the same time, the roller in the opening can change the sliding friction of the angle steel of the tower during the conveying process to rolling friction, so that the slider can push the angle steel of the tower more easily; furthermore, the upper and lower clamping arms set at the slider can clamp the inner and outer end faces of the angle steel of the tower to reposition it, thereby avoiding the unstable conveying situation caused by its cross-sectional shape, and transforming the unbalanced state of easy rolling and tipping into a stable state, eliminating safety hazards in the conveying process.

[0018] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the positioning and conveying fixture for the tower angle steel includes: a base 2, a support 3, a first conveying mechanism, and a second conveying mechanism; the support 3 is disposed on the base 2 and includes a first support body 301 and a second support body 302 arranged at an angle, with an opening 303 formed between the first support body 301 and the second support body 302, the opening 303 being V-shaped away from the base 2; the first conveying mechanism includes a plurality of rollers 4 near the top of the opening 303, which are rotatably disposed on the first support body 301 and the second support body 302 and support the tower angle steel 1; the second conveying mechanism includes a slider 5, an upper clamping arm 6, and a lower clamping arm 7, the slider 5 being slidably disposed at the bottom of the opening 303, the upper clamping arm 6 and the lower clamping arm 7 being disposed on the slider 5, and one of them being movable relative to the other to form a clamping point for clamping the inner and outer end faces of the tower angle steel 1.

[0019] Specifically, in this embodiment of the invention, the base 2 has a length direction, and a support 3 is provided along its length direction. The support 3 includes a first support body 301 and a second support body 302 arranged at an angle. Thus, a V-shaped opening 303 can be formed between the first support body 301 and the second support body 302. When the tower angle steel 1 (hereinafter referred to as "angle steel") is placed at the opening 303, it can fit with the cross-section of the angle steel, allowing the angle steel to be naturally embedded and located in the opening 303. During the conveying of the angle steel, the angle steel can be initially positioned due to the constraint of the two supports, preventing it from rolling or tipping over significantly. At the same time, the design of the opening 303 can also accommodate angle steel of different sizes, improving the versatility of this tooling.

[0020] In this embodiment of the invention, multiple rollers 4 are provided on the opposite inner walls of the opening 303, that is, both the first support 301 and the second support 302 are provided with rollers 4, so that the angle steel is supported by multiple rollers 4. At the same time, during the conveying process of the angle steel, the rollers 4 can be used to transform the original sliding friction into rolling friction, so that the angle steel can move smoothly.

[0021] In this embodiment of the invention, a second conveying mechanism is provided at the bottom of the opening 303 to push the angle steel towards the drilling station. This second conveying mechanism includes a slider 5 that can slide within the opening 303, and an upper clamping arm 6 and a lower clamping arm 7 disposed on the slider 5. Thus, the upper clamping arm 6 and the lower clamping arm 7 jointly clamp the inner and outer surfaces (or upper and lower surfaces) of the angle steel, and the slider 5 allows the angle steel to move along with it, thereby ensuring that the angle steel maintains the same posture during conveying and preventing deviation. Furthermore, the coordinated action of the first and second conveying mechanisms enables smooth and continuous conveying of the angle steel in a precisely positioned state, eliminating the problem of frequent manual intervention during production. Figure 2 As shown, the second conveying mechanism is located at one end of the angle steel; in other embodiments, two second conveying mechanisms can also be provided, located at both ends of the angle steel respectively, for clamping both ends of the angle steel and jointly conveying the angle steel to the designated position, thereby further improving the stability of the angle steel during the conveying process.

[0022] In this embodiment, the V-shaped opening 303 is adapted to the angle steel section to form a positioning reference, and the roller 4 can be used to achieve initial positioning. At the same time, the roller 4, slider 5, upper clamping arm 6 and lower clamping arm 7 can work together to change the angle steel from an unbalanced state that is prone to rolling and tipping over to a stable state. This not only eliminates safety hazards and ensures the safety of personnel and equipment, but also realizes continuous and stable conveying without manual intervention, which greatly improves production efficiency.

[0023] like Figure 1 , Figure 2 As shown, in one embodiment, the number of rollers 4 disposed on the first support 301 and the second support 302 is the same, and they are arranged in a one-to-one correspondence. Specifically, in order to improve the stability of the angle steel during the conveying process, this embodiment uses eight rollers 4, arranged in pairs, and disposed in a one-to-one correspondence at the first support 301 and the second support 302. In this way, the symmetrical layout ensures that the two flanges of the angle steel can obtain equal support points at the same time. During the conveying process, the weight and force of the angle steel can be evenly distributed to the rollers 4, effectively avoiding tilting or jamming of the angle steel due to uneven force, thereby achieving smooth and stable movement.

[0024] In other embodiments, the number of rollers 4 provided on the first support 301 and the second support 302 are different, and they are arranged in an alternating manner. In this way, the alternating arrangement of rollers 4 forms an asymmetrical, alternating constraint point on both sides of the angle steel, which can continuously and alternately fine-tune the running trajectory of the angle steel.

[0025] like Figure 1 , Figure 2 As shown, in one embodiment, a groove 304 is provided at the bottom of the opening 303, and the slider 5 is slidably disposed in the groove 304. Specifically, in order to enable the slider 5 to slide at the bottom of the opening 303, this embodiment provides a groove 304 at the bottom of the opening 303, which extends along the length direction of the base 2, allowing the slider 5 to slide back and forth in the groove 304, thereby enabling the sequential conveying of angle steel. The driving force of the slider 5 can come from an external motor (not shown).

[0026] like Figures 3-5 As shown, in one embodiment, the upper clamping arm 6 is movably disposed on the slider 5, and the lower clamping arm 7 is fixed to the slider 5. Specifically, in order to clamp or release the angle steel located between the upper clamping arm 6 and the lower clamping arm 7, this embodiment allows the upper clamping arm 6 to be movably disposed on the slider 5, and the lower clamping arm 7 to be fixed to the slider 5. This allows the upper clamping arm 6 to move relative to the lower clamping arm 7, thus giving the second conveying mechanism a clamping state and a releasing state. In the clamping state, the upper clamping arm 6 moves towards the lower clamping arm 7, reducing the distance between them, thereby clamping the angle steel between them to maintain a stable posture during transport. Conversely, in the releasing state, the upper clamping arm 6 moves away from the lower clamping arm 7, increasing the distance between them, thereby releasing the angle steel between them.

[0027] Furthermore, such as Figures 3-5 As shown, in one embodiment, the upper clamping arm 6 includes a movable part 601 and a clamping part 602 connected to each other. The movable part 601 is rotatably disposed on the slider 5 to move the clamping part 602 closer to or further away from the lower clamping arm 7. Specifically, in order to achieve the movable arrangement of the upper clamping arm 6 relative to the slider 5, this embodiment divides the upper clamping arm 6 into a movable part 601 and a clamping part 602. One end of the movable part 601 is rotatably disposed on the slider 5, and the other end is connected to the clamping part 602. Thus, when an external force is applied to the movable part 601, the movable part 601 can rotate in both directions, causing the clamping part 602 to move accordingly. This allows the clamping part 602 to press down and clamp the angle steel with the cooperation of the lower clamping arm 7, or to lift up and release the angle steel.

[0028] Furthermore, such as Figures 3-5As shown, in one embodiment, the slider 5 is movably equipped with a pull rod 8, which is connected to the movable part 601 and used to pull or push the movable part 601 to rotate forward and backward. Specifically, in order to enable the movable part 601 to rotate relative to the slider 5, this embodiment provides a pull rod 8 at the movable part 601; pulling or pushing the pull rod 8 can drive the movable part 601 to rotate forward and backward. Preferably, the pull rod 8 is provided with a self-locking structure to allow it to be suspended at any position. Figures 3-5 As shown, the self-locking structure is a threaded structure formed on the surface of the pull rod 8. In this embodiment, sleeves are provided at both the slider 5 and the movable part 601, allowing the pull rod 8 to extend into the sleeves sequentially. Rotating the pull rod 8 changes its length protruding from the slider 5, facilitating the pulling or pushing of the movable part 601 to rotate relative to the slider 5. Because the threaded structure has a self-locking effect, the movable part 601 can be fixed at any rotation angle using the pull rod 8, facilitating loading and unloading. Alternatively, the self-locking structure can be a hydraulic cylinder connected to the pull rod 8, using the self-locking force of the hydraulic cylinder to adjust the displacement of the pull rod.

[0029] like Figure 4 , Figure 5 As shown, the clamping part 602 is provided with a V-shaped protrusion 603 to fit the inner surface of the angle steel. The lower clamping arm 7 is provided with a V-shaped groove 701 to fit the outer surface of the angle steel.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
