Description

Technical Field

[0001] This utility model belongs to the field of processing technology of multi-faceted steel pipe towers, and in particular relates to a straightening and processing device for multi-faceted steel pipe towers. Background Technology

[0002] A polygonal steel pipe tower is a special type of steel pipe tower with a unique structure. It uses polygonal steel pipes as its main components, connected by plug-in joints to form a lattice-like tower frame. The main body of the tower is made of steel pipe, while other components may be combined with structural steel sections or guy wires to form a space truss structure. Due to its lightweight structure, convenient construction, and excellent wind resistance, the polygonal steel pipe tower is mainly used for overhead transmission lines. It supports conductors, lightning protection wires, and resists wind loads and other external forces, ensuring a safe distance between the conductors and the ground. It is widely used in various fields.

[0003] Comparing with Chinese Patent No. CN222695681U, a straightening and processing device for multi-faceted steel pipe towers is disclosed, including a ring frame. A first guide groove is formed through the right side of the ring frame, and a support platform is set in the first guide groove. Bearing wheels are evenly arranged at the bottom of the support platform. Two sets of fixed seats are evenly arranged on the left and right sides of the ring frame, respectively. A first sliding groove is formed on the top of the support platform and the inner side wall of the ring frame. The first sliding groove on the top of the support platform extends through the left and right sides of the support platform. Notches are formed on the front and rear sides of the inner side wall of the ring frame. The support platform can be moved left and right stably by guide blocks and by bearing wheels, thereby driving the multi-faceted steel pipe tower on the support platform to move left and right synchronously, so as to straighten the leftmost or rightmost end of the outer wall of the multi-faceted steel pipe tower.

[0004] However, the aforementioned patent can only move to various intermediate points to straighten the multi-faceted steel pipe tower, and lacks overall centering and positioning of the multi-faceted steel pipe tower. It is difficult to ensure that the surface of the multi-faceted steel pipe tower is uniformly stressed, and it cannot effectively eliminate deformation, thus reducing the straightening accuracy. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a straightening and processing device for multi-faceted steel pipe towers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A straightening and processing device for multi-faceted steel pipe towers includes a frame assembly for supporting the feed, and positioning components installed at both ends of the frame assembly for clamping, positioning, and rotating the multi-faceted steel pipe tower. A forming component for symmetrically rolling and straightening the multi-faceted steel pipe tower is disposed in the middle of the frame assembly. The frame assembly includes a frame body, with a rear wall body at the rear of the frame body. A feed mechanism for reciprocating feed is disposed on the rear wall body. The positioning component includes two symmetrically arranged clamping mechanisms, one of which has a drive mechanism at its outer end for providing rotational power. The forming component includes a movable frame, with first hydraulic cylinders symmetrically mounted vertically on the movable frame. A lifting frame is mounted on the telescopic end of each of the first hydraulic cylinders, and a pressure roller is rotatably mounted in the middle of the lifting frame.

[0007] Furthermore: the feeding mechanism includes two symmetrically arranged limiting slide grooves on the rear wall, a slide frame is slidably installed in the limiting slide groove, a connecting frame is installed behind the slide frame, a lead screw is installed in the middle of the connecting frame, and a first motor is provided at one end of the lead screw.

[0008] Furthermore, the rear wall body and the frame body are perpendicular and integrally formed.

[0009] Furthermore: the clamping mechanism includes a rotating seat connected to the end bearing of the frame body, two second hydraulic cylinders are symmetrically mounted on the rotating seat, and clamping plates are mounted on the telescopic ends of the second hydraulic cylinders; the driving mechanism includes a passive pulley mounted on the outer end of the rotating seat, an active pulley is arranged below the passive pulley, a transmission belt is installed between the active pulley and the passive pulley, and a second motor is arranged in the middle of the active pulley.

[0010] Furthermore: the clamping plate adopts a multi-faceted contour structure, and the transmission belt adopts a toothed belt.

[0011] Furthermore: the movable frame is a vertical rectangular frame with an open front end, and the movable frame and the slide are bolted together.

[0012] Furthermore, each of the lifting frames is symmetrically equipped with two of the first hydraulic cylinders.

[0013] Compared with existing technologies, the beneficial effects are: The automatic feeding, rolling, straightening, and face-changing operations of the multi-faceted steel pipe tower are achieved through a motor-driven lead screw feeding mechanism (first motor + lead screw + slide) and a rotary face-changing mechanism (second motor + pulley drive), which greatly reduces manual intervention and improves processing efficiency. The symmetrically arranged pressure roller assembly (first hydraulic cylinder + lifting frame + pressure roller) applies pressure synchronously in both directions, so that the upper and lower surfaces of the multi-faceted steel pipe tower are evenly stressed, effectively eliminating deformation and improving straightening accuracy. The multi-faceted contour clamping plate, in conjunction with two second hydraulic cylinders, ensures the stable clamping of the multi-faceted steel pipe tower end, preventing deviation during the straightening process; the rotating seat design supports precise face changing, ensuring consistent straightening of each facet. It can handle steel pipe towers with various numbers of edges, and adapt to different sizes through contour clamping plates and adjustable pressure rollers to meet diverse production needs; the whole process is mechanized (cylinder clamping, motor-driven face changing and feeding), reducing the intensity of manual operation and safety risks, and is especially suitable for batch processing scenarios.

The second motor 207; the clamping plate 203 adopts a multi-faceted contour structure, and the transmission belt 206 adopts a toothed belt; the two ends of the multi-faceted steel pipe tower are respectively inserted into the rotating seats 201 at both ends of the frame body 101. The rotating seats 201 support the extension of the second hydraulic cylinder 202 to push the clamping plate 203 to clamp and fix the ends of the multi-faceted steel pipe tower from the top and bottom. After the upper and lower surfaces are straightened, the second motor 207 drives the active pulley 205 to drive the passive pulley 204 to rotate through the transmission belt 206, so that the passive pulley 204 drives the rotating seat 201 to rotate and change the multi-faceted steel pipe tower until all the surfaces of the multi-faceted steel pipe tower are straightened. Then the multi-faceted steel pipe tower can be removed. In this embodiment: the forming component includes a movable frame 301, on which first hydraulic cylinders 302 are symmetrically mounted vertically.

The slide 104 drives the pressure roller 304 to move through the movable frame 301, and at the same time rolls the upper and lower surfaces of the multi-faceted steel pipe tower to straighten it.

[0019] Working principle: First, the two ends of the multi-faceted steel pipe tower are inserted into the rotating seats 201 at both ends of the frame body 101.

The limiting slide 103 on the body 102 moves, and the slide 104 drives the pressure roller 304 to move through the movable frame 301. At the same time, the upper and lower surfaces of the multi-faceted steel pipe tower are rolled and straightened. After completion, it is reset.

The passive pulley 204 drives the rotating seat 201 to rotate the multi-faceted steel pipe tower to change its surface. Then, the above steps are repeated until all surfaces of the multi-faceted steel pipe tower are straightened. After that, the multi-faceted steel pipe tower can be removed.
