Abstract

The invention relates to lifting devices, namely, winches with an axially movable drum. The purpose of the invention is to expand the technological capabilities of the winch. The winch includes a drum 1, a rope 2, a rope guide block 3, a drum 1 platform consisting of two parts 4 and 5 connected by a bridge and fasteners and supported by frames 8 on the winch 9 guides. The drum 1 is supported on the platform by bearings 10, 11, and 12. The mechanism for moving the drum 1 consists of a stop 13 connected to the shell of the drum 1 and a two-way screw 15 connected to the guides 9. The movement of the drum is communicated by a worm wheel 17 and a worm 18.6 or .

Description

The invention relates to lifting devices, namely, winches with an axially movable drum.

The purpose of the invention is to expand the technological capabilities of the winch.

Figure 1 shows a winch cut; figure 2 - block and limiter of the rope, top view; on fig.Z - fastening the stop on the side of the drum; Fig. 4 shows a winch, a slit, with a view of the support rollers and guides; figure 5 - connection of the telescopic part of the drum with the end of the worm wheel; in fig. 6 - use of the winch b1 as a jack.

The winch includes a drum 1, a rope 2, a rope guide block 3. The drum platform, consisting of two parts 4 and 5, connected by a jumper 6 and fastener 7, is supported by rollers 8 on the winch body 9. The drum 1 is supported on the platform by bearings 10, 11, and 12 (sliding bearings, for example, grefitof-toroplast). Movement mechanism

The drum consists of a stop 13, connected by fastener 14 to the shell of drum 1, and a two-way screw 15, connected by fastener 16 to guides 9. The movement of the drum is communicated by a worm gear 17 and a worm 18. The worm wheel is set relative to the sidewall 19 on one radial 20 and two axle bearings 21 and 22. The drum is telescopically connected through the slots of the shell 23 and the protrusions 24 of the drive shaft - the worm gear 17. Some cylindrical rod 25 can pass through the winch along the axis of the drum. The rope guide block can be rotated on the turntable 26 and secured with fastener 27. The winch body consists of sidewalls 28, fastened with fasteners 29.

To use the winch as a jack it is necessary to pass a cylindrical rod 25 through the hole in the center of the winch and attach the rope 2 in

the top of the rod 25 or to the bracket 30 in the wall. Rotating the handle 31 through the bracket 30, the winch raises the machine or item 32 (fig.b).

The winch works as follows. Rotation from the screw 18 is transmitted to the worm wheel 17, containing protrusions 24, through which the telescopic part of the drum 23 passes. At the other end of the drum shell, there is a stop 13, which carries the reciprocating movement of the drum 1 from the screw 15c to the left and right-hand thread, the pitch of which is equal to the step of winding the rope 2. The drum 1 rotates relative to the platform consisting of parts 4 and 5 in bearings 10, 11 and 12. The platform is supported by means of rollers 8 on the guides 9. Thanks to the reciprocating Moving block 3 is possible achivat turntable 26 through 360 ° in either direction.

Claims (1)

Invention Formula A winch containing a rope drum mounted in a housing axially guided along axially guides, is kinematically connected to the hull by means of a two-way screw and stop, and driven telescopically by means of protrusions on the drive shaft and slots on the drum side, characterized in that the purpose of expanding the technological capabilities of the winch, the drum is provided with a platform with bearings covering the drum shell and rollers in contact with the said guides fixed in the housing in which The aforementioned two-way screw is also fastened, and the stop is mounted on the drum side, with a through hole in the housing, the drum and the drive shaft of the winch. 17 14.
