The invention relates to iodine removal devices, namely, winches, which provide a predetermined rope tension.

The aim of the invention is to increase productivity and ease of operation with automatic tensioning and leveling of winches ropes.

 FIG. 1 shows a diagram of an alternating load; a load by means of an assembly mechanism; on fi1. 2 gras () of the mechanical characteristics of the electron; 1 operators and 1 holding and holding winches.

When installing the pipe driver on the track with a temporary slope of the engine compartment, track beams I with pe.nijcaMH 2 are poured, but with which a coupling link is loaded onto the slide of the 3 supports 3. 1 win, about 5 with drum and 6 installed in the lower part of the track, holding winch 7 with drums 8 and ropes 9. "The winches are powered by electric motors (not shown).

The movement of cargo is carried out as follows (. 2).

The electric motor holding winch 7 includes an artificial x) actuation 10 under it. At this m, the choice is made from: 1) the cables of the rope to the specified tension, after which the electrode will remain braked 1m under current. Then, the electric motor of the winch 5 is switched on for the natural characteristic 1 1 nod s.ma, which creates enough (r-1 moment to link - load 4, 1) eodo,: ieB static moment. and force 13 VC. Poheyny engine holding winch 7, starting, down movement. The coefficient of this reduction decreases, and the link-load begins to slide downwards but the rails 2 are on a speed;

the motor of the holding winch 7 is moment 14, determined by sliding friction. The electric motor of the holding winch does not return to countercurrent mode and creates a holding moment sufficient for transporting the link - load 4 downwards at the design speed.

Since the frequency of rotation of the electric motor of the winch 5 is approximately constant, and the winding diameter of the rope 9 on the drums 6 and 8 is variable, the electric motor of the holding winch 7 has a variable frequency of turns 15 and 16 proportional to the current ratio of the winding diameter of the rope on drums.

Claims (1)

Invention Formula 0 five The method of moving goods on a highway with a variable inclination, including the non-load-1E of the load by means of an assembly mechanism consisting of a traction and holding winches with electric motors and drums, i.e. M11ogos, is a rope winding, characterized by the fact that The purpose of 1i) B1 is labor productivity and convenience of work by automatically tensioning and leveling the speeds of the ropes. The winches, by turning on the drive, hold the win- dieri of the winches and choose the rope core to the specified tension, and after stopping this winch By turning this tension on without turning it off, the traction winch is switched and the load is shifted, while the electric motor of the holding winch is in counter-current mode with a variable rotation frequency proportional to the current value of the ratio of the diameter of the rope winding on the drums. , af / fn H P 35
