Abstract

The invention relates to a lifting and transport machinery industry and is intended for use in lifting devices for pressing a rope against a winch drum when winding and uncoiling a rope. . The purpose of the invention is to improve the reliability of the winch. On a common axis 9, levers 3 with roller 1 and levers 4 with roller 2 are installed in pairs. Levers 3 and 4 are pairwise connected by springs 5, while levers 3 are spring-loaded to the base by springs 6. The pressure roller deflects depending on the tension or weakening of the rope 1 with levers 3, and a moment is created relative to axis 9, which allows the levers 4 to turn and press roller 2 to the winch rope. 2 Il. from $ 00/00 00

Description

The invention relates to a lifting machinery industry and is intended for use in lifting devices to clamp 1 rope to the winch drum when winding and unwinding.

The purpose of the invention is to increase the reliability of the winch.

Fig, 1 shows a schematic of the clamping device, a general view; in fig. 2 - the same, in working condition.

Clamping rollers 1 and 2 are mounted at the ends of the articulated upper 3 and lower 4 levers. gi 3 and A are interconnected by a spring 5. The upper lever 3 is also connected to the base by a spring 6. The roller 1 is pressed against the rope 7 winding on the drum 8. The levers

3 and A are pairwise connected by a common axis.

9, mounted on the uprights 10 with the supports It, which serve to hold the levers 4. To one of the levers 3,

4 connected limit switch 12.

When the rope 7 is tensioned, the roller 1 with the rims 3 is in the initial position, f the spring 5 pulls the reel 4 away from the drum 8 with the roller 2 to the stop 11. When the rope 7 is loosened, the levers 3 under the action of the springs 6 tend to deflect the roller 1 to the drum 8 .Turning levers 3 relatively common

Axis 9 causes a change in the direction of action of the moment M generated by the springs 5.

Under the action of the moment M, the levers 4 with the rollers 2 turn over toward the drum 8 until the rope 7 is pressed against it. This prevents the rope from coming off the Oaraban thread, sagging and looping.

As a result of changing the position of the levers 3 and 4, limit switches 1 and 2 interlocked with the winch drive are turned on and off.

formula of invention

A winch rope pressing device comprising a pressure roller, the length of which is equal to the length of the drum, and this roller is mounted on two deflecting levers, which are spring-loaded relative to the base, so that winch, it contains two additional levers with an additional pressure roller mounted between them, both pairs of levers being pivotally connected by a common axis, and the levers are pairwise connected by a spring with the possibility of turning these levers relative to their common axis and so forth zhati additional roller to the winch rope.
