Abstract

The invention discloses a chimney avoiding device of a crane. The chimney avoiding device comprises a cylinder and a rotating table, wherein the rotating table is positioned on the cylinder; a crane jib and a jib lubbing mechanism for controlling the amplitude of the crane jib are arranged on the rotating table; a fan-shaped plate is arranged on the cylinder; a limiting switch I is arranged between the fan-shaped plate and the rotating table; the limiting switch I is a roller type limiting switch; the roller of the limiting switch I is matched with the fan-shaped plate to achieve rotary limiting of the crane jib; a collision block, a limiting switch II and a limiting switch III are arranged at the rear part of the crane jib; and the limiting switch II and the limiting switch III are matched with the collision block to limit the height of the crane jib. Due to combination of a limiting device and the fan-shaped plate, the crane arm of the crane can be automatically stopped without observation if the crane arm rotates back near an obstacle in the operation process, if the amplitude exceeds the height of the obstacle, the crane arm can be automatically rotated again, then possibility of mal-operation is avoided, and working safety and reliably of the crane can be ensured.

Description

technical field [0001] The invention relates to the technical field of crane safety control, and is mainly used in the case that there is an obstacle in the hoisting range of the crane. When the boom moves to the vicinity of the object, it is guaranteed to work normally after crossing the object, and specifically relates to a crane avoidance chimney installation. Background technique [0002] At present, cranes are widely used in docks, storage yards and other places to lift sand, gravel, ore, etc., but when the existing cranes are in operation, the operator generally controls the rotation, amplitude and The start and stop of lifting is therefore very inconvenient and not safe. Contents of the invention [0003] The object of the present invention is: aiming at the above-mentioned technical problems existing in the prior art, the present invention provides a crane avoidance chimney device, which can ensure the safety and reliability of the crane through the limit device a...
