Multi-arm hydraulic type bearing beam and travelling crane combined lifting device and lifting method thereof

Abstract

The invention discloses a multi-arm hydraulic type bearing beam and travelling crane combined lifting device and a lifting method thereof. The device comprises a lifting trolley and a bearing bracket which are arranged on a crane rail, wherein the bearing bracket comprises a bearing beam which is slidably arranged on the crane rail and a steel strand lifting jack which is vertically arranged on the upper side of the bearing beam; multiple end beams which horizontally extend outwards along the width direction are symmetrically arranged on two sides of the bearing beam; the lifting trolley is fixedly connected with the end beams; a through hole which penetrates through the upper side surface and lower side surface of the bearing beam is vertically formed in a position, which is positioned under the steel strand, of the bearing beam; the steel strand of the steel strand lifting jack passes through the through hole to extend to the lower part of the bearing beam, and the steel strand is in clearance fit with the through hole; and lifting hooks are respectively arranged at the lower part of the lifting trolley and on the steel strand positioned below the bearing beam. The device disclosed by the invention is simple in structure and high in bearing force, and the bearing capacity of the traditional lifting device and the safety in the lifting process are improved.

Description

technical field [0001] The invention relates to the technical field of electric installation lifting devices, in particular to a combined hoisting device of a multi-arm hydraulic load-bearing beam and a crane and a hoisting method thereof. Background technique [0002] With the rapid development of the national economy, the demand for electricity in all walks of life is increasing, and the quality and safety requirements for the power supply provided by the power supply department are also getting higher and higher. Therefore, the functional requirements for power supply equipment in the power industry It is particularly important; in order to meet the power supply demand, the existing power supply equipment has shown a trend of large-scale, heavy-duty collectivization and modularization. Such as the installation of generator sets, because the design of the lifting capacity of a single crane in the mechanical room of the generator set can only lift a single piece of eq...

AI Technical Summary

Problems solved by technology

Such as the installation of generator sets, because the design of the lifting capacity of a single crane in the mechanical room of the generator set can only lift a single piece of equipment, so in many cases it is necessary to use two cranes to lift synchronously; but in this case, the two cranes The total weight of the hoist cannot reach the weight of the installed equipment, resulting in a serious lifting capacity of the main workshop, and the limit of the hoisting height of the crane hook head is insufficient, which may easily cause problems in the safety of equipment installation.
