Gantry crane with adjustable span height

Abstract

The invention discloses a gantry crane with the adjustable span height. The gantry crane comprises a transverse moving mechanism and hydraulic lifting devices. One end of an I-shaped cross beam is fixedly connected with one hydraulic lifting device, the other end of the I-shaped cross beam is in sliding connection with the transverse moving mechanism, the transverse moving mechanism is fixedly connected with the other hydraulic lifting device, the transverse moving mechanism is used for transverse movement, and the hydraulic lifting devices are used for adjusting the height of the I-shaped cross beam. The height of the gantry crane is adjusted by designing the hydraulic lifting devices, the problem that the lifting height of a traditional gantry crane cannot be adjusted is solved, and the height applicability of the gantry crane is guaranteed; and furthermore, the single-side transverse free movement of the gantry crane is realized by designing the transverse moving mechanism, the problem that the span of a traditional gantry crane cannot be adjusted is solved, the stability and the span applicability of the gantry crane are ensured, the gantry crane with the adjustable span and height can be adjusted according to different lifting objects, height and span can be freely adjusted, and the application range is wide.

Description

technical field [0001] The invention relates to a gantry crane with adjustable span height, belonging to the technical field of hoisting. Background technique [0002] In mechanical processing and manufacturing workshops, warehouses, ports, laboratories and other places, a large number of heavy objects need to be moved every day, and hoisting equipment is required to complete the lifting and handling work. The application of gantry cranes has been popularized in various fields. At present, most of the existing traditional gantry cranes use a fixed frame structure. The lifting height and the width of the lifting parts are limited by their own frame size and are often not adjustable. Since the size of the lifting object is not uniform, if the size Larger gantry cranes are cumbersome and cumbersome to operate, which makes the gantry cranes inconvenient to move, time-consuming and labor-intensive; if a smaller gantry crane is used, it cannot be used for lifting objects of specia...

Problems solved by technology

At present, most of the existing traditional gantry cranes use a fixed frame structure. The lifting height and the width of the lifting parts are limited by their own frame size and are often not adjustable. Since the size of the lifting object is not uniform, if the size Larger gantry cranes are cumbersome and cumbersome to operate, which makes the gantry cranes inconvenient to move, time-consuming and labor-intensive; if a smaller gantry crane is used, it cannot be used for lifting objects of special sizes, and the lifting strength is low and the carrying capacity is low. Poor; the existing common elevating gantry cranes are limited to the lifting method. When lifting heavy objects and moving, they are completely supported by the elevating mechanism, which not only reduces the service life of the elevating mechanism but also reduces the safety and stability of the gantry crane.
