Manual cable bending machine

Abstract

The invention relates to a manual cable bending machine. The manual cable bending machine is characterized by comprising a body, a bending mechanism, a feeding mechanism and driving mechanisms, wherein the bending mechanism is arranged on the body and is fixedly connected with the body, the feeding mechanism is arranged on the body and on a side surface of the bending mechanism, a bottom surface of the feeding mechanism is fixedly connected with the body, an end is fixedly connected with the bending mechanism, the driving mechanisms are arranged on the body and at two sides of the feeding mechanism, a bottom surface of each driving mechanism is fixedly connected with the body, and a middle part of each driving mechanism is in contact with the feeding mechanism. The application method comprises the steps of calculating minimum bending diameter of a cable, placing fixed rollers in through holes at appropriate positions of the body, fixedly connecting the fixed rollers, placing the cablein the bending mechanism, locking the driving mechanism, simultaneously rotating handles of the driving mechanisms by two hands, driving a gear to rotate by the driving assembly, driving a rack and apush plate to move by the gear, wherein the push plate moves relative to the two fixed roller so that the cable is bent and is plastically deformed to achieve cable bending.

Description

technical field [0001] The invention relates to power supply engineering equipment, in particular to a power cable construction tool, which is a manual cable bending machine. Background technique [0002] At present, in the construction of power cables, in order to realize the effective connection with power supply equipment such as overhead lines, switch cabinets and metering facilities, it is necessary to use external forces to bend the power cables into a certain arc, so that the direction of the power cables can be effectively changed. It is called power cable bending. With the acceleration of the industrialization of small towns and the continuous advancement of the electrification of new rural areas, power supply companies and power customers have higher and higher standards for the design, construction, and maintenance of power facilities, and the awareness of safe power supply and use has gradually increased. Power cables The use has gradually gained popularity. Wi...

Problems solved by technology

In the traditional bending of power cables, the operator often estimates the bending length and the radian of the curve in advance, and uses his hands and other parts of the body, or two or more people to forcefully bend the cable into a certain curvature, which is very laborious and inefficient. The cable section reaches 95-120mm 2 , the bending work must be completed with the cooperation of two or more people at the same time, and the bending time is longer, and when the cable cross section reaches 120mm 2 When it is more than that, it is extremely difficult for the operator to complete it manually. It is necessary to fix one end of the cable with a foreign object and then force the other end to complete the bending. This will cause certain difficulties in the construction and maintenance of the power cable and the process is not standardized. , and it is very easy to cause damage to the outer skin of the power cable, and the labor intensity is high and the efficiency is low, which cannot meet the needs of power cable construction
