Description

The present invention relates to devices for winding and unwinding a flexible cable that feeds self-propelled machines, and differs from known similar devices in that for creating a constant tension of the cable, the rope is connected with a polyspast fitted with spring tension, and necks for placement of a rope made conical.

FIG. I depicts a device-general view, on phage. 2nd side view.

The drum / cable locator has three sections: an average 2-for cable and two extreme 3-for rope. The necks of the outer sections of the drum are made conical with threading for the rope. The drum rotates freely in supports located in brackets 4, which are attached to two vertical pipes 5. Inside each pipe there is a cylindrical spring 6, the lower end of which is fixed and the pulley is attached to the upper end of the spring. eight.

On the arms 9, mounted on vertical pipes 5, a vertical floor axis 10 is attached with a self-adjusting roller 11 for cable J2, which passes through the roller //, a hollow axis 10 and falls on the drum /, where it is fixed and exits through a horizontal hollow axis drum out.

When unwinding the cable from the drum with the ropes 13, winding on the tapered cheeks of the drum, with the help of the chain hoist 7, the springs 6 are stretched.

The extended springs 6, compressed, rotate the drum / with the help of the pulley 7 and the ropes, and the cable is wound up.

The taper of the cable drum puck is designed so that a constant torque of the cable section of the drum and, consequently, a constant cable tension, is ensured.
