Full-automatic anti-tipping device of crane

Abstract

The invention discloses a full-automatic anti-tipping device of a crane. The full-automatic anti-tipping device comprises supporting legs, hydraulic rods, a supporting mechanism, a fixing rod, a sliding rod, a telescopic spring, a fixing shaft, a clamping block, a rubber block, an abutting spring and an abutting mechanism. The full-automatic anti-tipping device has the advantages that the four supporting legs are detachably and fixedly connected with the four corners of the crane, under cooperation of the four hydraulic rods, the crane can be supported and stabilized, and the crane is prevented from rolling over; meanwhile, by pulling the sliding rod, the bottom of the sliding rod is clamped with the clamping block on the bottom side of the hydraulic rod, and under the action of the fixingshaft and the rubber block, the sliding rod is tightly clamped and is not prone to loosening, then under the action of the abutting mechanism, the sliding rod and the inside of the fixing rod cannotslide, and the supporting and reinforcing effects between the hydraulic rods and the supporting legs are achieved; and when the fixing rod is not used, the abutting mechanism is driven to store the sliding rod, then the fixing rod is rotated, and the fixing rod and the sliding rod are stored.

Description

technical field [0001] The invention relates to a crane, in particular to a fully automatic anti-overturning device for a crane, which belongs to the technical field of crane protection. Background technique [0002] Crane is a kind of lifting and handling equipment widely used in ports, construction sites, workshops and other places. It is the unified title of lifting machinery. In various fields and places, the most common ones are truck cranes and crawler cranes, which are important equipment for construction sites. In addition, cranes such as wharf cranes, tower cranes, and gantry cranes are also widely used. [0003] During the use of the crane, in order to prevent the crane from tipping over when lifting, it is necessary to install fully automatic support feet and hydraulic rods on both sides of the crane for support and protection. However, the traditional support feet have a single structure and poor compression resistance. When pressed, it will cause deformation be...

[0003] During the use of the crane, in order to prevent the crane from tipping over when lifting, it is necessary to install fully automatic support feet and hydraulic rods on both sides of the crane for support and protection. However, the traditional support feet have a single structure and poor compression resistance. When pressed, it will cause deformation between the support foot and the hydraulic rod, which will cause the crane to tip over
