Description

Technical Field

[0001] The utility model relates to the technical field of power transmission towers, in particular to a bending device for iron accessories of power transmission towers. Background Art

[0002] When assembling and constructing power transmission towers, many iron accessories are required. Some of these iron accessories are used for component connection, some for assisting climbing, and some for installing signs and markings. They have various functions and shapes. Some of the iron accessories are formed by bending iron plates. Since the thickness of the iron accessories is generally small, the hardness of the iron plates used for the iron accessories is not high, and the requirement for dimensional accuracy is relatively low. Therefore, large hydraulic equipment is not needed for bending, nor is it necessary to prepare special molds. Thus, a bending device with low cost, simple structure, and capable of quickly bending has extremely high practicality. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a bending device for iron accessories of power transmission towers, which has low cost, simple structure, can quickly bend, and has high practicality.

[0004] A bending device for iron accessories of power transmission towers of the utility model includes a platform, multiple legs, two backing plates, a pressing plate, a hardening plate, a pushing plate, a hydraulic cylinder, and a shaft rod. A square slot is provided at the right part of the platform. Multiple legs are installed on the lower end surface of the platform. Two backing plates are respectively and parallelly installed at the left part of the upper end surface of the platform. The two ends of the pressing plate are respectively connected to the right ends of the two backing plates. The hardening plate is installed on the right side wall of the pressing plate. The left end of the pushing plate is rotationally installed at the left end of the square slot of the platform. The upper end surface of the pushing plate is flush with the upper end surface of the platform. The moving end of the hydraulic cylinder is rotationally connected to the lower end surface of the pushing plate. The fixed end of the hydraulic cylinder is rotationally connected to the shaft rod. The two ends of the shaft rod are respectively connected to the two legs. The hydraulic cylinder is connected to an external hydraulic system. Place the iron plate of the iron accessory between the two backing plates. There is a small gap between the lower end surfaces of the pressing plate and the hardening plate and the upper end surface of the iron plate. Extend a certain length of the right end of the iron plate from under the pressing plate. Operate the hydraulic system to make the hydraulic cylinder extend. The moving end of the hydraulic cylinder pushes the pushing plate to turn up. The pushing plate pushes the right end of the iron plate to stand up. The lower right edge of the hardening plate blocks the iron plate, so that the iron plate is bent along the lower right edge of the hardening plate. When the upper end surface of the iron plate is completely in contact with the right side wall of the hardening plate, the bending is completed. Retract the hydraulic cylinder and remove the bent iron plate. It has low cost, simple structure, can quickly bend, and has high practicality.

[0005] Preferably, it further includes two height-adjusting plates, multiple pressing bolts, a thickness-adjusting plate and multiple high-strength bolts. The two height-adjusting plates are respectively installed between the pressing plate and the two backing plates. The multiple pressing bolts fasten the two ends of the pressing plate and the two height-adjusting plates to the two backing plates respectively. The thickness-adjusting plate is installed between the pressing plate and the hardening plate. The multiple high-strength bolts fasten the hardening plate and the thickness-adjusting plate to the right side wall of the pressing plate. According to the thickness of the plate, select two height-adjusting plates and a thickness-adjusting plate with appropriate thicknesses, and install the two height-adjusting plates and the thickness-adjusting plate between the pressing plate and the two backing plates and between the pressing plate and the hardening plate respectively through the multiple pressing bolts and the multiple high-strength bolts, so as to change the distance between the lower end surfaces of the pressing plate and the hardening plate and the upper end surface of the platform, and at the same time change the distance between the right end surface of the hardening plate and the upper end surface of the pushing plate when erected, enabling the device to bend iron plates with different thicknesses and improving the versatility of the device.
