High-stability portal crane

Abstract

The invention discloses a high-stability portal crane. The high-stability portal crane comprises a base plane, a warehouse, a left supporting leg and a right supporting leg; a warehouse door is formedin the left side of the warehouse, the base plane is butted with an entrance and exit of the warehouse door and installed, the right supporting leg and the left supporting leg are located above the base plane, and rail bodies are welded to the left side and the right side of the upper surface of the base plane; a grooved wheel body is installed at the left notch and the right notch of each rail body, and the two sets of grooved wheel bodies are connected with wheel body installation bases through bearings. According to the high-stability portal crane, connecting rods are welded to positions,close to the upper portions, of the two sets of homodromous double rods and used for supporting a butt-joint plate, and after the angle of the left supporting leg and the angle of the right supportingleg are well adjusted, a supporting bone rod connected to the middle of the left supporting leg and the middle of the right supporting leg are in a transverse state, the left supporting leg and the right supporting leg are supported and positioned, so that the left supporting leg and the right supporting leg are stable, and meanwhile, a transverse tool installed on the upper surface of the supporting bone rod is used for lifting and displacing an object.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a high-stability gantry crane. Background technique [0002] Gantry crane is a deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargoes, and bulk cargoes. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. [0003] The application aims to improve the existing technology. Most of the gantry cranes in the prior art are single-axis lifting when lifting objects. , and the existing gantry cranes still have defects in the installation of the lifting frame. For example, af...

Problems solved by technology

[0003] The application aims to improve the existing technology. Most of the gantry cranes in the prior art are single-axis lifting when lifting objects. , and the existing gantry cranes still have defects in the installation of the lifting frame. For example, after installation, most of the frames are welded. The lifting frame and the supporting frame are connected through nuts, which is prone to increase the installation and disassembly time. Secondly, the nuts The installation part is covered, and there is a certain risk factor for personnel when the nut is installed on the transverse surface of the lifting frame.
