Description

TECHNICAL FIELD

[0001] The present application relates to the field of hoisting and transportation technology, and in particular to a multifunctional combined gantry crane system and its installation and use method. BACKGROUND

[0002] Hoisting equipment refers to electromechanical equipment used for carrying or moving heavy objects. Most hoisting equipment starts vertical or vertical and horizontal work travel after taking materials, unloads after reaching the destination, and then returns to the material taking point to complete a work cycle, and then performs the second lifting or carrying. Generally, hoisting equipment works in sequence of taking materials, moving and unloading, and the work of each corresponding mechanism is intermittent.

[0003] Hoisting equipment is widely used in various industries, and can be divided into several categories such as small and light hoisting equipment, elevators, cranes and overhead monorail systems according to different structures. Among them, the cranes used for hoisting large equipment mainly include crawler cranes and bridge cranes (including gantry cranes), but these two types of hoisting equipment require a larger operating site and are limited in some applications.

[0004] At present, the single hoisting weight of large rolling mill portal has exceeded 500 tons, and the height has exceeded 16 meters, which is super high and super heavy for the crane in the rolling mill workshop. Therefore, other hoisting equipment must be used to lift and slide into place before installation. Hoisting equipment often adopts the combination of gantry and hydraulic lifting device.

[0005] A Chinese invention patent with the authorized announcement number CN 106517009 B discloses a "hoisting tool for large portal and its construction method". The hoisting tool includes a frame support, a bearing beam and a lifting module. The top of the frame support is provided with a horizontal bearing beam. The lifting module includes a lifting oil cylinder, a lifting tool and a steel cable. The lifting oil cylinder is connected with the lifting tool by a steel cable. The lifting tool includes an upper lifting frame, a connecting plate, a rotating frame and an upper rotating shaft. The lifting hydraulic oil cylinder of the lifting module is vertically fixed on the bearing beam. A rotating support is arranged between the rotating frame and the connecting beam. The hoisting tool adopts a process combining steel cable hydraulic synchronous lifting device and rotating balance, which integrates pushing, lifting and rotating.

[0006] Chinese patent application publication number CN115924707A discloses a "large-scale rolling mill frame hoisting method," comprising: 1) installing a ground-level sliding device and a hydraulic lifting and sliding device; 2) hoisting the transmission-side frame onto the ground-level sliding device, installing a hoisting fixture and a center-of-gravity adjustment device; 3) hoisting the transmission-side frame above the installation location using the hydraulic lifting and sliding device as the primary lifting mechanism, with the workshop crane assisting with the tail lift; 4) completing the installation of the transmission-side frame; 5) installing the operating-side frame onto the rolling mill base in the same manner as steps 2) to 4); and 6) installing the rolling mill crossbeam. This method is suitable for working conditions where the workshop crane cannot meet the lifting capacity and lifting height requirements. It utilizes a "ground-level sliding + vertical lifting followed by aerial sliding + aerial flipping" method to achieve horizontal transportation and vertical hoisting of the rolling mill frame. The hydraulic lifting and sliding device it adopts is composed of an operating side column, a transmission side column, a main sliding track beam, a main sliding beam, a main sliding hydraulic jacking device, a transverse support beam, a longitudinal support beam and a hydraulic lifting device; the two main sliding track beams are arranged in parallel, and the two ends of each main sliding track beam are supported by a transmission side column and an operating side column respectively. The transmission side column is correspondingly arranged on the transmission side of the rolling mill, and the operating side column is correspondingly arranged on the operating side of the rolling mill; the top of the main sliding track beam is respectively provided with a main sliding beam, and the main sliding beam can move along the main sliding track beam under the drive of the main sliding hydraulic jacking device; the two transverse support beams and the two longitudinal support beams are staggered in a crisscross shape on the top of the main sliding beam, and a group of hydraulic lifting devices are respectively provided in the middle of the two longitudinal support beams, and a rigging is provided at the bottom end of the steel hinge wire in the hydraulic lifting device.

[0007] While lifting equipment combining a gantry and hydraulic lift can meet the needs of hoisting large rolling mill arches, it suffers from large dimensions and difficult transportation. Most equipment is fabricated and installed on-site, making it difficult to reuse the equipment after mill installation. This results in low equipment turnover and high construction costs. Furthermore, the lifting equipment's relatively fixed dimensions make it difficult to adapt to different mill models. Summary of the Invention
