A simple hoisting support frame for safe hoisting of gantry cranes

Abstract

The purpose of the present invention is to solve the problem that the existing gantry cranes are difficult to hoist in batches, and discloses a simple hoisting support frame for safe hoisting of gantry cranes, including a first set of boxes, a support frame, a mounting rod, a second A motor, the first rack, the first turntable, fastening screws, sliders, guide grooves, connecting rods, clamps, screws, splints, anti-slip layers, switches, support plates, hanging ropes, connecting frames, sliding rods, stoppers block, the second rack, the second box, the positioning plate, the frame, the second motor, the second turntable, the rotating shaft, the wire, the guide cylinder, the first through slot and the second through slot; the present invention rationally utilizes the second motor The lifting of the support plate is controlled, and the front and rear movement of the support plate is controlled by the first motor, thereby helping to realize the batch lifting of goods, and the design is reasonable, the operation is convenient, safe and reliable.

Description

technical field [0001] The invention relates to the field of gantry cranes, in particular to a simple hoisting support frame used for safe hoisting of gantry cranes. 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] However, the existing gantry cranes are generally hoisted in a single piece when hoisting, and the efficiency is low when hoisting. Sometimes it is not easy to carry out batch lifting, and it is necessary t...

Problems solved by technology

[0003] However, the existing gantry cranes are generally hoisted in a single piece when hoisting, and the efficiency is low when hoisting. It is necessary to make the hook of the gantry repeatedly slide along the guide rail of the gantry. It is not easy to lift in batches, and it is troublesome to use a trolley to carry it. Therefore, it is urgent to design a simple lifting support frame for the safe lifting of the gantry crane to solve the deficiencies in the prior art.
