0.75 Ton Hydraulic Winch Type Cable Puller Tensioner In Overhead Transmission
Brief Introduction
A transmission line tension stringing and aerial cableway erection job tension of the tension machine. The liner is fixed round groove of the main driven wheels arranged in parallel composition, and a diameter of the driven wheel driving wheel diameter 0.6 to 0.95, the master, the driven wheel two further fixed wheel and two or more groove substrate. When the wire is rotated by external traction rounds, only the large diameter drive wheel braking force that is applied. Selection round slot liner material of different coefficient of friction the wire by force, to avoid wire lantern, to protect the wire and release the tension wheel uniform wire. While the whole weight, smaller in size and lower cost.
Principle
Tension machine tension control mechanism by a mechanical drive mechanism and hydraulic control system, in exhibition put the cable (or wire), the additional tension cable (wire) on the mechanism by actinomycetes, sprockets growth mechanism, the spread on the motor so that rotation of the motor acts as a pump, motor outlet received a direct-acting relief valve acts as a regulator, the implementation of remote control. By adjusting the pressure relief valve, the pressure generated moment of resistance and the role of oil, oil pressure forming torque equilibrium. In this case, the size of the outlet pressure of the hydraulic motor can be continuously adjusted regulator from small to large, proportional to the tension of the cable machine actinomycetes agencies (wire) on the tension. After the regulator of pressure settings, not put off tension affect line speed.
Application
It is for the development of passive tension machine is put self-supporting aerial cables and small tension wires specially designed ground. It has a simple structure, easy operation and stable.
Structure
Mainly by the growth of tension sprocket wheel, hydraulic control system, braking mechanism, frame and other components. The hydraulic control system mainly consists of low speed high torque motor,, direct-acting relief valve and sucked back into the oil filter.
