An intelligent crimping platform for high-voltage transmission wires

Abstract

The invention discloses an intelligent pressure welding platform suitable to high voltage power transmission lines and belongs to the field of power delivery line construction devices. The platform includes a guide rail pressure welding carriage, a horizontal moving oil cylinder, a pressing jaw trolley, a pressing jaw, a displacement sensor, a gasoline engine hydraulic pump and a programmable controller. The guide rail pressure welding carriage includes a pedestal and a line clamp. The horizontal moving oil cylinder is arranged on the guide rail pressure welding carriage. The horizontal moving oil cylinder is connected to the gasoline engine hydraulic pump through a hydraulic pipe. The pressing jaw trolley is fixed on the horizontal moving oil cylinder. The pressing jaw is installed on the pressing jaw trolley and is connected to the gasoline engine hydraulic pump. The displacement sensor is disposed on the guide rail pressure welding carriage and is in separate connection to the pressing jaw trolley and the programmable controller. The programmable controller is connected to the gasoline hydraulic pump. Compared with prior art, the platform can use the programmable controller to realize digital control in the process of pressure welding, and a pressure sensor acquires pressure signals to achieve accurate control in the process of pressure welding. The platform increases construction efficiency, safety and reliability.

Description

technical field [0001] The invention belongs to the field of power transmission line construction equipment, and in particular relates to an intelligent crimping platform suitable for high-voltage transmission wires. Background technique [0002] The national key project Lingzhou-Shaoxing ±800 kV HVDC transmission line project used JL1 / G3A-1250 / 70, L1 / G2A-1250 / 100 and other large cross-section ACSR for the first time. The wire has the characteristics of many layers of aluminum strands, a large ratio of aluminum to steel, and a high percentage of the tensile force of the aluminum wire to the calculated breaking force of the wire. It can greatly increase the transmission power of the power line when used in power transmission, reduce the loss of the line, and reduce the loss of the transmission line. Surface field strength, radio interference, audible noise, and project cost. However, due to the large cross-section of the wire used, higher requirements are placed on the crimp...
