Abstract

The invention relates to an electro-hydraulic grab bucket mechanism for a portal crane, in particular to a mechanism applied to a portal crane an dused for grabbing bulk cargoes such as steel scrap, garbage, medicinal materials and the like, and belongs to the technical field of hoisting and handling equipment. The electro-hydraulic grab bucket mechanism mainly comprises an operating platform, a lifting mechanism, a pulley mechanism, a cable, a base support, a cable take-up basket, a hook and a grab bucket, wherein, the base support is positioned at the top end of the portal crane; the operating platform and the lifting mechanism are positioned on the base support; the pulley mechanism is positioned on the upper surface of the head part of the base support; the hook is connected with the lower end of the pulley mechanism through a steel wire rope; the cable take-up basket is positioned on the cable; the upper end of the cable is connected in the operating platform, and the lower end of the cable is connected with the grab bucket; and the grab bucket is positioned at the lower end of the hook. The electro-hydraulic grab bucket mechanism has the advantage of simple, compact and reasonable structure, and is very easy in maintenance, overhaul and replacement; and as the electro-hydraulic grab bucket mechanism can efficiently and safely grab the special bulk cargoes such as the steel scrap, the garbage, herbal medicines and the like, the working application range of the portal crane is enlarged, the cost is lowered and the output value is increased.

Description

technical field [0001] The invention relates to an electro-hydraulic grab mechanism for a gantry crane, specifically for grabbing scrap steel, rubbish, medicinal materials and other bulk goods on the gantry crane, and belongs to the technical field of lifting and unloading equipment. Background technique [0002] In the prior art, the gantry cranes all use mechanical grabs. When the mechanical grabs are used to grab the goods, because the force of the grabs to grab the goods cannot be controlled, the controllability of the grabs is not strong, and the efficiency is low. low. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned weak point, thereby provides a kind of electro-hydraulic grab mechanism for gantry crane; The scope of application of the gantry crane has reduced the cost and increased the output value. [0004] According to the technical solution provided by the present invention, the electro-hydraulic grab mechan...
