Overload limiting equipment for tower crane

Abstract

The invention discloses overload limiting equipment for a tower crane. The overload limiting equipment comprises a device body, a case and an installing frame, wherein the case is fixedly arranged onthe outer surface of the device body; the installing frame is fixedly arranged under the case; an information processor is arranged inside the case and is fixedly arranged in the case; batteries are arranged at the two sides of the information processor; the batteries and the information processor are in parallel arrangement; an A / D converter is arranged right under the information processor, andis fixedly arranged in the case. The overload limiting equipment for the tower crane is provided with a plurality of warning lamps and an amplitude increaser; the plurality of warning lamps are arranged at equal intervals; when the crane is used for conveying other equipment, and the overload of the crane occurs, the warning lamps can automatically illuminate according to the conditions; construction personnel can perform secondary monitoring on the overload problem of the equipment according to the observation result on the illumination condition of the warning lamps; the amplitude increasercan enhance information sent from the gravity sensor, so that the work efficiency of the crane is ensured.

Description

technical field [0001] The invention relates to the technical field of overload limiting equipment, in particular to overload limiting equipment for tower cranes. Background technique [0002] At present, the height limit of cranes generally uses mechanical contact elements to control the height. It is generally composed of a body, a connecting rod and a rolling joint. There are tension springs, contacts, and terminals inside the body. It is widely used in various constructions. The use of various devices has also increased. [0003] However, during the use of existing tower cranes, the safety of the equipment itself is often easily overlooked. As a result, when the crane is transporting other equipment, the overweight of the crane itself cannot be detected in time, resulting in accidents of the crane, resulting in casualties and economic losses. loss. Contents of the invention [0004] The object of the present invention is to provide an overload limiting device for a t...
