Description
Technical Field
[0001] This utility model belongs to the technical field of power steel pipe tower production equipment, and in particular, it is a power steel pipe tower steel plate bending and pushing device. Background Technology
[0002] Power transmission steel pipe tower steel plates are steel plates with specific properties and specifications, mainly used in the manufacture of steel pipe towers for power transmission lines. As an important supporting structure for overhead transmission lines, steel pipe towers need to possess sufficient strength, stability, and durability to withstand the weight of conductors, ground wires, and external forces such as wind and ice loads. Traditional power transmission steel pipe tower steel plate bending and pushing devices can meet basic usage requirements, but their self-adaptive pushing ability is weak, and increased manual intervention causes uneven forces on the steel plates during bending, resulting in quality defects such as surface scratches, wrinkles, and even cracks, reducing product quality and service life.
[0003] A search revealed Chinese patent document (authorization announcement number CN210816829U), indicating that this utility model is a steel plate bending device, mainly used for processing transition arc flange plates in steel structures with H-beams as members. It solves the problem of a lack of processing devices for transition arc flange plates. The hydraulic jack continues to move upwards, causing the flat steel plate to bend and deform, forming a transition arc that matches the arc-shaped cylindrical surface of the module's lower surface. The use of this steel plate bending device can accelerate construction progress and reduce the frequency of hazardous operations. This utility model features a simple and reasonable structure, flexible operation, ease of use, and fast workpiece processing speed. While the device can meet basic usage requirements, its self-adaptive pushing ability is weak, increasing the need for manual intervention. This leads to uneven force on the steel plate during bending, resulting in surface scratches, wrinkles, and even cracks, reducing product quality and service life. Utility Model Content
[0004] The purpose of this utility model is to provide a bending and pushing device for steel plates of power steel pipe towers to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a power steel pipe tower steel plate bending and pushing device, comprising a base for supporting the power steel pipe tower steel plate bending and pushing process, a support frame installed on the top of the base, and an adaptive box provided between the base and the support frame;
[0006] The adaptive box has a sliding cross groove inside, and a rigid spring and a buffer spring are connected inside the cross groove. One end of the rigid spring and the buffer spring is connected to a cross post. The end of the cross post is slidably disposed inside the cross groove. A position sensor for early warning is installed on the inner top wall of the adaptive box, and a receiver for use with the position sensor is installed on one end of the cross post.
[0007] Preferably, a protective plate is installed at the other end of the cross post, and a motor is installed on the side of the protective plate.
[0008] Preferably, the output shaft of the motor is connected to a bending wheel for bending and pushing the steel plate of the power steel pipe tower via a coupling, and the bending wheel is rotatably disposed inside the protective plate.
[0009] Preferably, a fixing seat is installed on the top of the base, and a bending seat for bending the steel plate of the power steel pipe tower is installed on the top of the fixing seat. A rotating shaft is rotatably connected inside the fixing seat.
[0010] Preferably, the outer periphery of the rotating shaft is equipped with a pusher wheel for assisting in pushing the steel plate of the power steel pipe tower, and the groove of the fixed seat is provided with a strip hole for the pusher wheel to make contact with the steel plate of the power steel pipe tower during bending and pushing.
[0011] Preferably, a hydraulic cylinder for providing extrusion and bending force is mounted on the top of the support frame, and a movable rod is mounted on the movable part of the hydraulic cylinder, the end of which is mounted to the top of the adaptive box.
[0012] Preferably, four guide rods for limiting the position are welded to the top of the base.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This power steel pipe tower steel plate bending and pushing device benefits from the adaptive box structure. When the bending wheel contacts the power steel pipe tower steel plate, the steel plate squeezes the bending wheel. The bending wheel drives the protective plate and cross column to squeeze the rigid spring and buffer spring. The cross column drives the receiver to move closer to the position sensor. The position sensor processes the position signal of the receiver and reminds the operator whether the bending force is overloaded, thus protecting the equipment from damage. Compared with the traditional power steel pipe tower steel plate bending and pushing device with weak adaptive pushing ability, this structure increases the adaptive pushing ability, reduces manual intervention, and prevents the steel plate from being subjected to uneven force during bending, thereby producing quality defects such as surface scratches, wrinkles, or even cracks, improving product quality and service life.
[0015] This power steel pipe tower steel plate bending and pushing device benefits from the structure of the bending wheel and the pushing wheel. The motor drives the bending wheel to rotate slowly, and the bending wheel drives the power steel pipe tower steel plate to move. The rotation of the pushing wheel facilitates the movement of the power steel pipe tower steel plate. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0026] like Figures 1 to 5 The power steel pipe tower steel plate bending and pushing device shown includes a base 1 for supporting the power steel pipe tower steel plate bending and pushing process, a support frame 101 is installed on the top of the base 1, and an adaptive box 2 is provided between the base 1 and the support frame 101.
[0027] The adaptive box 2 has a sliding cross groove 201 inside, and a rigid spring 202 and a buffer spring 203 are connected inside the cross groove 201. The outer periphery of the spring is damped. One end of the rigid spring 202 and the buffer spring 203 is connected to a cross post 206. The end of the cross post 206 is slidably disposed inside the cross groove 201. A position sensor 204 for early warning is installed on the inner top wall of the adaptive box 2. A receiver 205 for use with the position sensor 204 is installed on one end of the cross post 206. A bending wheel 302 and a bending wheel 305 are also installed inside the cross post 206. The bending seat 403 bends the steel plate of the power steel pipe tower. When the bending wheel 302 contacts the steel plate, the steel plate compresses the bending wheel 302. The bending wheel 302 drives the protective plate 3 and the cross post 206 to compress the rigid spring 202 and the buffer spring 203. The cross post 206 drives the receiver 205 to move closer to the position sensor 204. The position sensor 204 processes the position signal from the receiver 205. After converting the detected position information into electrical signals, the position sensor 204 transmits these signals to the receiver 205. The receiver 205 is a module with signal processing function. It receives the electrical signals from the position sensor 204 and further processes and analyzes them to remind the operator whether the bending force is overloaded, thereby protecting the equipment from damage.
[0028] At the other end of the cross post 206, a protective plate 3 is installed for protection. A motor 301 is installed on the side of the protective plate 3. The output shaft of the motor 301 is connected to a bending wheel 302 for pushing the steel plate of the power steel pipe tower through a coupling. The bending wheel 302 is a cylindrical metal wheel with a specially treated surface, which has high hardness and wear resistance. The rim is usually designed with a specific shape and size to accommodate the bending requirements of steel plates of different thicknesses and widths. For example, the rim may be a V-shaped or U-shaped groove, and the angle and depth of the groove are designed according to common bending angles and steel plate thicknesses. By contacting the surface of the steel plate, the bending wheel 302 applies pressure and bending moment to the steel plate using its rotational motion and the shape of the rim, causing the steel plate to gradually bend to the required angle. The bending wheel 302 is rotatably positioned inside the protective plate 3.
[0029] A fixed seat 4 is installed on the top of the base 1. A bending seat 403 for bending the steel plate of the power steel pipe tower is installed on the top of the fixed seat 4. A rotating shaft 401 is rotatably connected inside the fixed seat 4. A pushing wheel 402 for assisting in pushing the steel plate of the power steel pipe tower is installed on the outer periphery of the rotating shaft 401. A strip hole is provided in the groove of the fixed seat 4 for the pushing wheel 402 to contact the bending and pushing of the steel plate of the power steel pipe tower. When the motor 301 is turned on, the motor 301 drives the bending wheel 302 to rotate slowly. The bending wheel 302 drives the steel plate of the power steel pipe tower to push. The rotation of the pushing wheel 402 facilitates the movement of the steel plate of the power steel pipe tower.
[0030] A hydraulic cylinder 102, which provides the bending force, is mounted on the top of the support frame 101. The hydraulic cylinder 102 operates based on Pascal's principle. When hydraulic oil enters one chamber of the cylinder through the oil port, the oil pushes the piston under pressure, and the piston, through the piston rod, moves the external load. Simultaneously, oil in the other chamber is discharged through the oil port. By controlling the flow rate and pressure of the hydraulic oil, the movement speed and output force of the piston rod can be precisely controlled, thereby achieving precise control of the steel plate bending and pushing process. For example, when bending a steel plate, the pressure and stroke of the hydraulic cylinder 102 can be adjusted to precisely control the pressure and bending angle applied to the steel plate by the bending wheel. The movable part of the hydraulic cylinder 102 is equipped with a movable rod 103, the end of which is installed on the top of the adaptive box 2. Four guide rods 104 for limiting are welded to the top of the base 1. The steel plate of the power steel pipe tower to be bent is placed on the V-groove of the bending seat 403. The movable part of the hydraulic cylinder 102 extends, driving the movable rod 103 and the adaptive box 2 to move downward. The adaptive box 2 drives the protective plate 3 to move downward, and the protective plate 3 drives the bending wheel 302 to contact the steel plate of the power steel pipe tower.
[0031] Working principle
[0032] In use, the power steel pipe tower steel plate bending and pushing device first places the power steel pipe tower steel plate to be bent on the V-groove of the bending seat 403. The movable part of the hydraulic cylinder 102 extends, driving the movable rod 103 and the adaptive box 2 to move downwards. The adaptive box 2 drives the protective plate 3 to move downwards, and the protective plate 3 drives the bending wheel 302 to contact the power steel pipe tower steel plate. Finally, the bending wheel 302 and the bending seat 403 bend the power steel pipe tower steel plate. When the bending wheel 302 contacts the power steel pipe tower steel plate, the power steel pipe tower steel plate squeezes the bending wheel 302. The bending wheel 302 drives the protective plate 3 and the cross column 206 to compress the rigid spring 202 and the buffer spring 203. The cross column 206 drives the receiver 205 to move closer to the position sensor 204. The position sensor 204 processes the position signal of the receiver 205 to remind the operator whether the bending force is overloaded, thereby protecting the equipment from damage. The motor 301 is turned on, and the motor 301 drives the bending wheel 302 to rotate slowly. The bending wheel 302 pushes the steel plate of the power steel pipe tower. The pushing wheel 402 rotates, which facilitates the movement of the steel plate of the power steel pipe tower.
