SU1511793A1 - Device for winding/unwinding cable from drum - Google Patents

Abstract

The invention relates to the mechanization of work related to the winding of cables, cables, ropes and similar elements on the drums and their unwinding. The purpose of the invention is to increase labor productivity while ensuring the safety of service personnel. The device comprises a support frame consisting of two parallel parts in which guides are made. On the frame there are two pairs of coaxially arranged rolling rollers, with one pair of rollers connected by a telescopic shaft driven by an electric motor. Another pair of rolls is connected with the transfer screw-nut and lever and forms an ejector mechanism, with the rolls being mounted with the possibility of longitudinal movement along the guides. 1 hp ff, 6 ill.

The device for unwinding and winding the cable onto the drum consists of the following nodes; The rack I consisting of the base 2, the walls 3 and the guides 4, made of sectional steel, has holes 5 (FIG. 2) for installing the adjustable ejector mechanisms 6. Between the walls of the rack 1, the roll 7c is mounted with bearing supports. a shaft 8 terminated in a half coupling 9. The device also comprises a rack 10 (Fig. 6) with a gearbox II () housing, which is a welding structure similar to that of the rack 1. Between the walls 2 of the rack 10 is mounted coaxially with the roll 7, a similar raskatochny roll 13 with bearing supports. The shaft 14 of the roll 13 on one side ends with a coupling half 15, on the other - gear D

The second wheel 16, which is included in reducer 11 o. Reducer is a two-stage axle. A flanged four-speed electric motor 17 is mounted on the gearbox wall, on which shaft there is a fixed gear wheel 18 ". A switch of 19 poles (fig.6) for switching motor speeds is mounted on the upper part of the reducer. In addition, two coaxially disposed (ejected) are also included in the device kit roll 20 mounted in a rack 21. On the wall of the stand, in its lower part, rollers 22 are mounted (Fig. 43) to move the push roller 20 along guide 4. Roll 20 together with the stop 23 (Fig. 2 ), the pusher screw 24 (Fig. 5), the nut 25, which is connected to the rotational movement by means of the lever 26 with the ratchet mechanism 27, forms a adjustable push-out mechanism 6 "

The device works as follows

The guides 4 are installed between the flanges of the cable drum 28 (fig. 6) until the flange stops against the rolls 7 and 13 of the uprights 1 and 10. When the telescopic shaft 8 is moved, the coupling half 9 and 5o are engaged. After turning and displacing the telescopic shaft, it is fixed by fixing 29 (FIGHT).

The 4 pillars 1 and 10 are mounted on the coaxially pushing rollers 20 and the pusher screws 24. As the nuts 25 are rotated, the pusher screws 24 move along the 4 guides and work through the pushing rollers. 20 on the flanges of the cable drum 28 and, as if squeezed, lift it. The multi-speed motor 17 through the gearbox 11 moves and transmits the rotation to the shaft 14 of the unrolling roll 13 in the rack with the gearbox and through the coupling 15 to the telescopic shaft B and the unrolling roll 7 in the rack 1. The cable drum 28 rests on the rollers 7, 13, 20, which, rotating cuddle, carry the drum around and spin it.

The proposed device for unwinding and winding the cable on the drum

four

It has a number of advantages over the well-known analogous purpose, namely, it provides for the complete mechanization of the processes of lifting, rotating, and braking drums with a cable when pro-. masonry, lifting cable reels of any diameter (dimension); allows winding the cable onto the drum in field conditions, in the ToCh, when dismantling the cable lines; provides rotation and braking of the rotating cable reel In addition, the device is simple to manufacture, safe and secure in operation due to the lack of the need to install an axis, hanging the actuator with the support bracket due to the transfer of reactive torque directly to the base frame of the device resting on the base surface .
