Problems solved by technology

At present, the commonly used α-type hoist for hanging baskets has a long pressure roller mechanism lever, a large spring rigidity, and a small pressure roller. When the hanging basket is in normal operation, the wire rope will have a slight jump, which is easy to damage the pressure roller and cause the rope to enter. The position of the port and the position of the output force hole are not in a straight line, slightly eccentric, which is not conducive to power transmission

Abstract

The invention relates to an operating mechanism of a hoisting device, in particular to an operating mechanism of a hoisting machine for nacelles, and the mechanism comprises a case having an upper edge with a rope inlet, and is characterized in that a rope pulley is installed inside the case, the excircle of the rope pulley is provided with a V-shaped groove, and the upper part has an L-shaped compacting wheel mechanism. An end of a lever close to the rope inlet is provided with a compacting wheel, and the other end is provided with a pull rod. The pull rod is provided with a spring. One end of the spring is against a spring base, and the other end is sealed on the pull rod by a pull rod cover and a pin roll. A lateral face of the case is provided with a rope outlet. The other side corresponding to the compacting wheel and a rope division block is matched with an arc retainer ring on the excircle of the rope pulley. The operating mechanism of a hoisting machine for nacelles has stable and reliable work, simple structure, small volume, low manufacture cost and long service life.

Description

technical field [0001] The invention relates to a working mechanism of a lifting device, in particular to a working mechanism of a hoist for a hanging basket. Background technique [0002] As a kind of electric lifting decoration machine, the hanging platform for high-altitude operation is widely used in the exterior wall construction and decoration and decoration engineering of high-rise and multi-storey buildings. The hoist is the power device of the gondola for working at heights and plays a vital role. At present, the commonly used α-type hoist for hanging baskets has a long pressure roller mechanism lever, a large spring rigidity, and a small pressure roller. When the hanging basket is in normal operation, the wire rope will have a slight jump, which is easy to damage the pressure roller and cause the rope to enter. The position of the port and the position of the output force hole are not in a straight line, and are slightly off-center, which is not conducive to power...
